Note: The standard lifting door is equipped with a wire rope break anti fall device or a torsion spring

break protection device. When designing the torsion force of the torsion spring, more consideration must

be given. It is necessary to ensure that when the door body is opened to the top position normally, the

anti fall blade is prevented from getting stuck on the track and the winding disc does not rotate due to the

anti break wheel getting stuck on the torsion spring shaft.

If a wire rope breakage and fall protection device is installed, a buffer (door pusher) must be installed at

the rear end of the track.

Ndustrial Door Torsion Spring

During the up and down operation of an industrial door with a sliding track, the power to overcome the weight of

the door panel is mainly balanced by the torsion spring force of the balance system. The motor only plays a part of

the lifting force and limit function during the up and down operation traction. Therefore, the relationship between the

design load frequency, balance force, and weight of the door panel of the torsion spring is crucial for the normal and

safe operation of the door body. The industrial door torsion springs designed and manufactured by Fuxing Spring

Factory are designed according to the manual opening effect when on-site installation conditions allow. The door

body can be manually opened to any position and can remain balanced.

Design:

According to the size of the door body, the total weight of the door body, the number of working loads required by

the customer (i.e. the fatigue number of the torsion spring), the opening and lifting method, the model of wire wound

wheel is selected, and the surrounding installation conditions are used for the most scientific and safe design.

The safest and most cost-effective design principle: Design a balance system that is safe and balanced, easy

to open, uses the lightest material weight, has the lowest cost, and has the best effect according to customer

requirements.

texture of material:

60Si2MnA oil quenched and tempered steel wire, 65Mnoil quenched and tempered steel wire, or 82B high-strength

spring steel wire.

Due to the frequent opening of industrial doors, the total weight of the door body is large, the lifting method is special,

and the stress of the torsion spring changes frequently, so tensile strength is required for the material. High Elastic

Limit, good toughness, uniform continuity, good tempering stability, smooth surface, commonly used 60Si2MnA oil

quenched steel wire.

Heat treatment:

A 4-meter-long continuous conveyor mesh belt type electrically controlled tempering furnace adopts an imported

Omron temperature controller and automatic control system, with high temperature control accuracy. The hot air

mixing device ensures accurate and balanced furnace temperature, and the effect is good after heat treatment.

Rust prevention treatment:

According to the steel wire material and customer requirements, rust prevention treatment is carried out, including

water film replacement rust oil, hard film rust prevention oil, cold blue white zinc, yellow zinc, surface shot blasting,

electrophoresis, blackening, phosphating, painting, spraying, dacromet and other processes.

Torsion test:

There is a dedicated industrial door torsion spring testing device for torque testing.

Safety points for the use of industrial doors:

1、 Safe and reliable design of the balance system;

2、 Torsion spring fatigue fracture protection device;

3、 Wire rope fracture protection device;

4、 Lead aluminum alloy specialized steel rope buckle, stamping

processing;

5、 The diameter and length of zinc aluminum alloy winding wires are

symmetrical on both sides;

6、 Side mounted door opener, equipped with a buffered booster;

7、 The installation requirements for industrial door guide rails and support rails are parallel and vertical;

8、 Extra wide door body with external reinforcing ribs;

9、 Quenching treatment of industrial door rollers;

10、 On site installation requires that the torsion spring and steel wire rope can only be installed after all welding

processes are completed, in order to prevent the torsion spring and steel wire rope from breaking under force due to

contact with welding.

工业门提升方式分为上滑道提升、完全垂直提升和半垂直三种，其扭簧安装如下：

1、上滑道提升工业门：和上滑道车库门的扭簧安装方法相同。

2、完全垂直提升工业门：因为扭簧始终承受着相同重量的门体，只有靠改变轮径的大小，即改

变扭矩大小，才能使扭簧扭力和门重平衡，所以需要安装塔轮。

完全垂直提升工业门扭簧安装时需要预紧。钢丝绳的长度必须根据塔轮线盘来确定，要保证门体

开启到顶部时，钢丝绳在塔轮上从大圈到小圈全部绕满。

3、半垂直提升工业门：需要安装半塔轮才能使扭簧扭力和门重平衡，门垂直提升时用半塔轮的

塔轮部分，门上滑部分提升时用半塔轮的平轮部分。

半垂直提升工业门的扭簧安装时也需预紧。钢丝绳的缠绕方法为：垂直部分先从半塔轮的大圈绕

到小圈，且要绕满，然后上滑部分继续绕在半塔轮的平轮上，平轮上的圈数则根据门体上滑部分的提

Necessary Data Sheet for Industrial Door Torsion Spring Design

Door panel size (width x height) Door panel weight Weight of accessories Lifting method Required fatigue times

Installation method for industrial door torsion spring:

The lifting methods of industrial doors are divided into three types: upward slide lifting, fully vertical lifting, and semi vertical lifting. The

installation of the torsion spring is as follows:

1. Upslide lifting industrial door: the installation method of the torsion spring is the same as that of the Garage door on the upper slide.

2. Fully vertical lifting industrial door: Because the torsion spring always bears the same weight of the door body, only by changing the

size of the wheel diameter, that is, changing the torque size, can the torsion spring torque and the door weight be balanced, so tower

wheels need to be installed.

When installing the torsion spring of a fully vertical lifting industrial door, it needs to be pre tightened. The length of the steel wire rope

must be determined based on the tower wheel coil, ensuring that when the door body is opened to the top, the steel wire rope is fully

wound from the large circle to the small circle on the tower wheel.

3. Semi vertical lifting industrial door: It is necessary to install a half tower wheel to balance the torsion spring torque and door weight.

When lifting the door vertically, the tower wheel part of the half tower wheel is used, and when lifting the sliding part of the door, the flat

wheel part of the half tower wheel is used.

The torsion spring of the semi vertical lifting industrial door also needs to be pre tightened during installation. The winding method of

steel wire rope is as follows: the vertical part should first be wound from the large circle to the small circle of the half tower wheel, and

it should be fully wound. Then, the upper sliding part should continue to be wound on the flat wheel of the half tower wheel, and the

number of turns on the flat wheel should be determined based on the lifting height of the upper sliding part of the door body.

一、滑升门的几种提升方式及对应的钢丝绳轮

1、标准提升（90°翻板）：用直径不变的平轮。

2、垂直提升（包括斜提升）：用直径均匀变化的圆锥型塔轮。

3、高位提升（半垂直提升）：用塔轮与平轮相组合的半塔轮。

二、为什么标准提升一定要用直径不变的平轮？常用平轮有几种规格及适用范围？

标准提升门开闭过程是门体由水平轨向垂直轨运行，直至完全关闭。所产生门体的重量是

逐渐增加，最后完全由扭簧平衡系统承担，而在这个关闭过程中，扭簧的扭转圈数逐渐增多，

被扭转角度变大，所产生的扭力与门体关闭过程中增加的重力相对应成正比。所以根据材料力

学设计原理只要改变扭簧的扭转角度经过直径不变的平轮就能产生与门体重力相对应的扭力。

三、为什么垂直提升门一定要用直径变化的圆锥塔轮？

垂直提升门在开启关闭过程中，门体始终处于垂直状态，门的全部重量都需要扭簧平衡系

统来承担，由于上下运行过程中，门体重量是不变的，改变的只是扭簧的被扭转角度。为保证

扭簧在不同的被扭转角度下能产生与门体重量相同的平衡力，根据力学设计原理就需要均匀的

改变钢丝绳轮的直径。即门体关闭过程中，扭簧被扭转角度逐渐变大，钢丝绳轮的直径也逐渐

变大，呈正比关系，所产生的平衡力不变，所以垂直提升门一定要用直径均匀变化的塔轮。

四、为什么高位提升门一定要用塔轮与平轮相组合的半塔轮有几种规格适用范围？

根据标准提升门及垂直提升门的运行理论类推，高位提升门在垂直提升过程中钢丝绳应绕

在塔轮部位，才能保证扭簧的扭力与门体的重量平衡，门体运行到标准提升状态时钢丝绳处于

平轮部位，才能保证扭簧的扭力与门体重量平衡，所以一定要用半塔轮。

五、扭簧加工常用材料有哪几种？

72B 碳素弹簧钢丝：抗拉强度 1350-1550 之间，用于车库门扭簧

82B 高强度碳素弹簧钢丝：抗拉强度 1550-1650 之间，用于工业门扭簧

60Si2MnA 油淬火调直合金弹簧钢丝，抗拉强度 1550-1650 之间，用于工业门扭簧

六、滑升门扭簧常用的几种法兰？

车库门：1-3/4 寸，2 寸，2-5/8 寸 工业门：2-5/8 寸，3-3/4 寸，5-1/4 寸，6 寸

七、工业门扭簧中间为什么要放内衬？

放内衬是为了防止在安装过程中，扭簧中间部位因自重的原因产生弯曲现象。

Several lifting methods and corresponding steel wire rope wheels for sliding doors

1. Standard lift (90 ° flap): Use a flat wheel with constant diameter.

2. Vertical lifting (including inclined lifting): Use conical tower wheels with uniform diameter

changes.

3. High level lifting (semi vertical lifting): A semi tower wheel combined with a flat wheel.

Why is it necessary to use a flat wheel with the same diameter for standard elevation? What

are the specifications and application range of commonly used flat wheels?

The standard lifting door opening and closing process is when the door body runs from the horizontal

rail to the vertical rail until it is completely closed. The weight of the generated door body gradually

increases and is ultimately borne entirely by the torsion spring balance system. During this closing

process, the number of torsion coils of the torsion spring gradually increases, and the angle of torsion

increases. The torque generated is proportional to the increased gravity during the door body closing

process. Therefore, according to the design principle of Strength of materials, as long as the torsion

angle of the torsion spring is changed and passes through the flat wheel with the same diameter, the

torsion force corresponding to the gravity of the door body can be generated.

Why is it necessary to use conical tower wheels with varying diameters for vertical lift

doors?

During the opening and closing process of a vertical lifting door, the door body is always in a

vertical state, and all the weight of the door needs to be borne by the torsion spring balance system.

As the weight of the door body remains unchanged during the up and down operation, the only change

is the angle at which the torsion spring is twisted. To ensure that the torsion spring can produce a

balance force equal to the weight of the door body at different angles of torsion, it is necessary to

uniformly change the diameter of the steel wire rope wheel according to the principles of mechanical

design. During the closing process of the door body, the angle of torsion of the torsion spring gradually

increases, and the diameter of the steel wire rope wheel also gradually increases, in a proportional

relationship. The generated balance force remains unchanged, so it is necessary to use a tower wheel

with uniform diameter changes to vertically lift the door.

Why is it necessary to use a half tower wheel combined with a tower wheel and a flat wheel

for a high level lifting door? How many specifications are applicable?

According to the operation theory of standard lifting doors and vertical lifting doors, during the vertical

lifting process of high level lifting doors, the steel wire rope should be wound around the tower wheel to

ensure that the torque of the torsion spring is balanced with the weight of the door body. When the door

body runs to the standard lifting state, the steel wire rope is in the flat wheel position to ensure that the

torque of the torsion spring is balanced with the weight of the door body, so half tower wheels must be

used.

What are the commonly used materials for torsion spring processing?

72B carbon spring steel wire:tensile strength between 1350 and 1550, used for torsion spring of

Garage door

82B high-strength carbon spring steel wire: tensile strength between 1550-1650, used for

industrial door torsion springs

60Si2MnA oil quenched straightening alloy spring steel wire, with a tensile strength between 1550

and 1650, used for industrial door torsion springs

How many flanges are commonly used for sliding door torsion springs?

Garage door: 1-3/4 \", 2\", 2-5/8 \"Industrial door: 2-5/8\", 3-3/4 \", 5-1/4\", 6 \"

Why should a lining be placed in the middle of the industrial door torsion spring?

The lining is placed to prevent bending of the middle part of the torsion spring due to its own

weight during installation.

卷帘门、窗平衡系统 ROLLER SHUTTER AND WINDOW BALANCE

卷帘门、窗平衡系统

电动卷帘门、窗在停电时一般采用 3 种方式启用。

一、手遥杆：费力、启闭时间长，开门机限位容易跑位；

二、后备电源：蓄电池维护麻烦、寿命较短、成本高；

三、扭簧平衡系统：使用小功率电机既能启闭门体，手动开门比较方便、可靠。

卷帘门平衡系统并不能象上滑门平衡系统一样，能使门体在任意位置都能平衡停留，门体只

是在顶部与底部能轻松手动平衡，在中间需用力抬起。这是由于扭簧扭转变形后所产生的扭力与门

体开启的高度、重量不成正比所决定的。如果要使门体在中间部平衡，则安装时需要增加圈数。

增加圈数以后启闭效果：门体在顶部自动向上提升，向下关闭到底部时，需增加较大的外力

向下压，在中间能手动平衡。

卷帘门、窗平衡系统 ROLLER SHUTTER AND WINDOW BALANCE

Roller shutter and window balance system

Electric Roller shutter doors and windows are generally enabled in three ways in case of power failure.

1、 Hand remote lever: labor-intensive, long opening and closing time, easy to move the door opening machine limit;

2、 Backup power supply: Battery maintenance is troublesome, with a short lifespan and high cost;

3、 Torsion spring balance system: Using a low-power motor can open and close the door body, and manual opening

is more convenient and reliable.

The balance system of Roller shutter can not make the door stay balanced at any position like the balance system of

upper sliding door. The door can be easily balanced manually at the top and bottom, and it needs to be lifted forcefully

in the middle. This is determined by the fact that the torque generated by the torsion spring after torsion deformation

is not directly proportional to the height and weight of the door opening. If you want to balance the door body in the

middle, you need to increase the number of turns during installation.

After increasing the number of turns, the opening and closing effect: The door body automatically lifts upwards at

the top, and when closing downwards to the bottom, a large external force needs to be added to press downwards,

allowing for manual balance in the middle.
