产品介绍 Product Introduction

1、标准液压螺母 Standard Hydraulic Nut

液压螺母原理、特点： Features of Hydraulic Nuts

① 主体② 驱动环③ 液压油腔④ 加压螺钉⑤ 加压扳手

① Body
② Drive ring
③ The hydraulic oil chamber
④ Tightening screw
⑤ Pressure wrench液压螺母是利用等静压膨胀原理的一款紧固螺母产品，工作时仅需拧紧其外圆上的加压螺钉，对内部液压介质进行压缩，液压介质产生巨大的压强作用于驱动环，使驱动环输出较大的轴向力。主要用于滚刀装夹、工件压紧等需轴向输出力的应用场合。
在使用液压螺母对滚刀杆进行锁紧的场景中，仅需手动将液压螺母旋至与垫圈贴合，然后使用T 型扳手拧紧加压螺钉，随即可输出较大的轴向力，压紧滚刀。

与普通锁紧螺母相比，具有如下优势：
1. 省力。
2. 滚刀装夹精度高。
3. 滚刀杆精度及寿命保持性好。
4. 锁紧可靠。

The hydraulic nut is a fastening product based on the isostatic pressure expansion principle. During operation, simply tighten the pressure screws on its outer circumference to compress the internal hydraulic medium. This generates tremendous pressure acting on the driving ring, which then outputs a significant axial force. Primary applications on hobbing cutter clamping, workpiece pressing and other scenarios requiring axial force output.

Operational examples on hob arbor, just manually thread the hydraulic nut until it contacts the washer, tighten the pressure screws with a T-handle wrench to instantly generate high axial force, securing the roller cutter.

1.Minimal manual torque required.
2.High clamping precision.
3.Preserves hob arbor integrity.
4.Reliable locking.

使用说明 Operating Instruction

该液压螺母内置有加压活塞, 能够提供强大的端面预紧力，使用前请认真、完整阅读以下使用说明及注意事项，避免不当使用造成产品的损坏。 This hydraulic nut features an integrated pressure piston that generates high axial preload force. Please read the following instructions and safety precautions carefully and completely before use to prevent product damage due to improper operation.

、产品结构 Product Structure

二、使用步骤 Operating Steps

加压螺钉至少退至螺纹挡圈下端面

The tightening screws must be retracted at least to the lower and face.

1. 先将两颗加压螺钉退出至上图位置或完全退出。
2. 将液压螺母连接到螺杆上，并旋紧至使驱动环端面与被压工件贴合，可根据使用工况通过手动预紧扳手孔进一步预紧螺母。
3. 液压螺母上刻有分别拧紧一颗加压螺钉和两颗加压螺钉时，液压螺母所能提供的端面压力，可根据实际使用需求拧紧加压螺钉的数量。 4. 拧紧加压螺钉后，可观察压力指示器中间圆柱上红线的露出数量，一般加压一颗螺钉露出1 条红线，加压两颗螺钉露出2 条红线（小规格产品 只露出一条红线），可根据此方法判断液压螺母是否起作用。
5. 拆卸螺母时应先松加压螺钉，再松螺母。
1.Fully retract or remove both tightening screws to the position shown in the diagram abave.
2.Thread the hydraulic nut onto the stud/bolt until the driving ring end face contacts the workpiece. For additional preload, use the manual wrench flats to further tighten the nut as needed.
3. The hydraulic nut is marked with pressure ratings for tightening one pressure screw and two pressure screws. Select the number of screws to tighten based on application requirements.
4. After tightening the screws, check the pressure indicator:
1 red line exposed \mathbf { \Sigma } = \mathbf { \Sigma } One screw tightened (standard preload)
2 red lines exposed \mathbf { \Sigma } = \mathbf { \Sigma } Two screws tightened (higher preload)
(Note: Smaller models may only show 1 line regardless of screw count.) This confirms whether the hydraulic nut is functioning correctly. 5. Always loosen the pressure screws first before unscrewing the nut.

三、注意事项 Precautions

以下注意事项对液压螺母的正确使用至关重要，请仔细阅读。

1. 如使用时发现液压螺母的压力不足（压力指示器无法正常显示）时，可能是在使用过程中导致驱动环露出螺母主体太多，可以先将加压螺钉完
全退出，再将液压螺母装入螺杆，用扳手拧手动预紧扳手孔，缩短驱动环相对螺母主体的露出量。
2. 液压螺母上的相关配件严禁拆卸，否则会造成液压油泄露。
3. 液压螺母在没有使用时，严禁拧紧液压螺母上的加压螺钉，否则会导致液压螺母上的端面驱动环脱落或无法复位，影响正常使用。
4. 对于非正常使用造成的液压螺母损坏，我司不负责维修。

The following precautions are critical for proper use of the hydraulic nut. Read carefully before operation.
1.If the hydraulic nut fails to generate adequate pressure (no visible indicator movement), the driving ring may be over-extended from the nut. Firstly, fully retract both pressure screws, then, reinstall the nut onto the stud/bolt, use a wrench on the manual preload flats to reduce the driving ring's protrusion.
2.Do not disassemble any components of the hydraulic nut. Risk: Hydraulic oil leakage, irreversible damage.
3.Never tighten the pressure screws when the nut is uninstalled (no axial load applied).Risks: driving ring may detach or fail to reset, and permanent functional impairment.
4.Warranty exclusion: damage caused by misuse, improper operation, or unauthorized modifications voids all maintenance liabilities.
