The electric shear wrench is mainly used to tighten the shear type high-strength bolt, and its purpose is to break the box head of the shear type high-strength bolt. The electric torque shear wrench is equipped with two sockets inside and outside. The outer sleeve is used to torque the nut, apply torque to the bolt, and the inner sleeve is used to torque the box head. The two torques are equal in size and opposite in direction. Unscrew the box head at the end and read the pre tension value. Here is the basic knowledge of electric shear wrench:

电动扭剪扳手的基本知识是什么？

What is the basic knowledge of electric shear wrench?

一．电动扭剪扳手的使用方法

1、 How to use the electric wrench

1.将扳手的内套筒完全插入螺栓末端的盒头中，同时向前推动扳手，内套筒向后移动，使外套筒完全盖住螺母。如果不能完全盖住螺母，请左右转动扳手并用力向前。

1. Insert the inner sleeve of the wrench fully into the box head at the end of the bolt, while pushing the wrench forward, the inner sleeve moves backward, so that the outer sleeve completely covers the nut. If the nut cannot be completely covered, turn the wrench left and right and force it forward.

2.转动扳手开关使其旋转。

2. Turn the wrench switch to rotate.

3.拧下梅花头，拧紧，然后扣动扳机弹出梅花头。

3. Screw off the plum blossom head, tighten it, and then pull the trigger to eject the plum blossom head.

二．如何更换电动扭剪扳手的内外套筒？

2、 How to replace the inner and outer sockets of the electric wrench?

在开始更换操作之前，检查弹射杆是否伸入内套筒。如果没有，操作顶出销伸出，然后更换。

Before starting the replacement operation, check whether the ejection rod extends into the inner sleeve. If not, operate the ejector pin to extend and replace it.

拆卸套筒时，拉动顶杆。当意外触碰弹射扳机时，它可能会突然弹出。

Pull the ejector rod when removing the sleeve. When the ejection trigger is accidentally touched, it may suddenly pop out.

1.每个套筒分为内部和外部零件，拆卸时，先取出外套筒，然后取出内套筒。

1. Each sleeve is divided into internal and external parts. When disassembling, take out the outer sleeve first, and then take out the inner sleeve.

2.准备并拧紧适合螺栓类型的内外套筒。

2. Prepare and tighten the inner and outer sleeves suitable for the bolt type.

3.套筒的拆卸：用力按压外套管，用六角螺丝刀拆下主体和外套管之间的连接，然后按压弹射杆，以防弹射造成伤害。

3. Dismantle the sleeve: press the outer sleeve with force, remove the connection between the main body and the outer sleeve with a hexagon screwdriver, and then press the ejection rod to prevent injury caused by ejection.

三．电动扭剪扳手的应用：产品可用于剪切型高强度螺栓的初始拧紧，拧紧需要使用剪切扳手，因此剪切扳手专门用于剪切型高强螺栓的拧紧。

3、 Application of electric shear wrench: the product can be used for the initial tightening of shear type high-strength bolts. Shear wrenches are required for tightening, so shear wrenches are specially used for tightening shear type high-strength bolts.

四．电动扭剪扳手的工作原理：电动扭力剪扳手有内外两个套筒。外套管扭转螺母，向螺栓施加扭矩。内套筒扭转盒头。两个扭矩大小相等，方向相反，直到拧下末端的箱头。然后拔出扳手并扳动扳机，弹出盒头，这就结束了工作。

4、 Working principle of electric torque shear wrench: the electric torque shear wrench has two sockets inside and outside. Twist the nut on the outer sleeve to apply torque to the bolt. Twist the box head of the inner sleeve. The two torques are equal in size and opposite in direction until the box head at the end is unscrewed. Then pull out the wrench and pull the trigger to eject the box head, which ends the work.

四．电动扭剪扳手的优点

4、 Advantages of Electric Twist Shear Wrench

1.体积小、重量轻、扭剪速度快，可提高施工效率。

1. Small size, light weight and fast torsional shear speed can improve the construction efficiency.

2.产品电机采用德国原装进口，比国产电机体积小、功率大。

2. The motor of the product is imported from Germany with original packaging, which is smaller in volume and higher in power than the domestic motor.

3.整机人性化设计，手柄采用人体工程力学原理，握持更舒服。

3. The whole machine is humanized design, and the handle adopts the principle of human engineering mechanics, making it more comfortable to hold.

4.电源线是一种由TPU材料制成的特殊电缆，通常用于恶劣的工作条件。它具有优异的耐磨性、抗弯性和抗滚动性。它的是同规格电缆的3倍多，但可以完全防止电缆断裂的问题

4. Power cord is a special cable made of TPU material, which is usually used in harsh working conditions. It has excellent wear resistance, bending resistance and rolling resistance. Its price is more than 3 times that of cables of the same specification, but it can completely prevent cable breakage

5.这个机器齿轮由超高强度钢制成，强度是普通钢的两倍

5. The machine gear is made of ultra-high strength steel, which is twice as strong as ordinary steel

6.电动扭剪扳手相对容易操作，降低了工人的劳动强度，提高了工作效率。现在市场上有很多电动扳手的制造商，所以选择一个好的产品制造商很重要。

6. The electric shear wrench is relatively easy to operate, reducing the labor intensity of workers and improving the work efficiency. There are many manufacturers of electric wrenches on the market, so it is important to choose a good manufacturer.
