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:

電動(dòng)扭剪扳手的基本知識(shí)是什么？

What is the basic knowledge of electric shear wrench?

一．電動(dòng)扭剪扳手的使用方法

1、 How to use the electric wrench

1.將扳手的內(nèi)套筒完全插入螺栓末端的盒頭中，同時(shí)向前推動(dòng)扳手，內(nèi)套筒向后移動(dòng)，使外套筒完全蓋住螺母。如果不能完全蓋住螺母，請(qǐng)左右轉(zhuǎn)動(dòng)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.轉(zhuǎn)動(dòng)扳手開(kāi)關(guān)使其旋轉(zhuǎn)。

2. Turn the wrench switch to rotate.

3.擰下梅花頭，擰緊，然后扣動(dòng)扳機(jī)彈出梅花頭。

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

二．如何更換電動(dòng)扭剪扳手的內(nèi)外套筒？

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

在開(kāi)始更換操作之前，檢查彈射桿是否伸入內(nèi)套筒。如果沒(méi)有，操作頂出銷伸出，然后更換。

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.

拆卸套筒時(shí)，拉動(dòng)頂桿。當(dāng)意外觸碰彈射扳機(jī)時(shí)，它可能會(huì)突然彈出。

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

1.每個(gè)套筒分為內(nèi)部和外部零件，拆卸時(shí)，先取出外套筒，然后取出內(nèi)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.準(zhǔn)備并擰緊適合螺栓類型的內(nèi)外套筒。

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

3.套筒的拆卸：用力按壓外套管，用六角螺絲刀拆下主體和外套管之間的連接，然后按壓彈射桿，以防彈射造成傷害。

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．電動(dòng)扭剪扳手的應(yīng)用：產(chǎn)品可用于剪切型高強(qiáng)度螺栓的初始擰緊，擰緊需要使用剪切扳手，因此剪切扳手專門(mén)用于剪切型高強(qiáng)螺栓的擰緊。

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．電動(dòng)扭剪扳手的工作原理：電動(dòng)扭力剪扳手有內(nèi)外兩個(gè)套筒。外套管扭轉(zhuǎn)螺母，向螺栓施加扭矩。內(nèi)套筒扭轉(zhuǎn)盒頭。兩個(gè)扭矩大小相等，方向相反，直到擰下末端的箱頭。然后拔出扳手并扳動(dòng)扳機(jī)，彈出盒頭，這就結(jié)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．電動(dòng)扭剪扳手的優(yōu)點(diǎn)

4、 Advantages of Electric Twist Shear Wrench

1.體積小、重量輕、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.產(chǎn)品電機(jī)采用德國(guó)原裝進(jìn)口，比國(guó)產(chǎn)電機(jī)體積小、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.整機(jī)人性化設(shè)計(jì)，手柄采用人體工程力學(xué)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.電源線是一種由TPU材料制成的特殊電纜，通常用于惡劣的工作條件。它具有優(yōu)異的耐磨性、抗彎性和抗?jié)L動(dòng)性。它的是同規(guī)格電纜的3倍多，但可以完全防止電纜斷裂的問(wèn)題

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.這個(gè)機(jī)器齒輪由超高強(qiáng)度鋼制成，強(qiáng)度是普通鋼的兩倍

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

6.電動(dòng)扭剪扳手相對(duì)容易操作，降低了工人的勞動(dòng)強(qiáng)度，提高了工作效率?，F(xiàn)在市場(chǎng)上有很多電動(dòng)扳手的制造商，所以選擇一個(gè)好的產(chǎn)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.
