扭矩电动扳手各种类型的使用

来源:http://fhgfx.com 日期:2020-11-04 发布人:admin

扭矩扳手又叫力矩扳手、扭力扳手,一般分为两类:定扭矩电动扳手和定扭矩手动扳手。

Torque wrench also known as torque wrench, torque wrench, generally divided into two categories: constant torque electric wrench and constant torque manual wrench.
定扭矩电动扳手又叫扭矩可调电动扳手,是电动扳手的一种,其更主要特征就是可以设定扭矩,并且扭矩可调。
Constant torque electric wrench, also known as torque adjustable electric wrench, is a kind of electric wrench. Its main feature is that the torque can be set and the torque can be adjusted.
二、应用
2、 Application
电动扳手主要应用于钢结构安装行业,专门安装钢结构高强螺栓,高强度螺栓是用来连接钢结构接点的,通常是用螺栓群的方式出现。
The electric wrench is mainly used in the steel structure installation industry, which is specially used to install the high-strength bolts of steel structure. The high-strength bolts are used to connect the joints of steel structures, usually in the form of bolt groups.
高强螺栓可分为扭剪型和大六角型两种,国标扭剪型高强螺栓为M16、M20、M22、M24四种,现在也有非国标的M27、M30两种;国标大六角高强螺栓为M16、M20、M22、M24、M27、M30等几种。一般的对于高强螺栓的紧固都要先初紧再终紧,而且每步都需要有严格的扭矩要求。大六角高强螺栓的初紧和终紧都必须使用定扭矩扳手。
High strength bolts can be divided into torsion shear type and large hexagon type. There are four kinds of national standard torsional shear high-strength bolts: M16, M20, M22, M24, and now there are also non-national M27 and M30; national standard large hexagon high-strength bolts are M16, M20, M22, M24, M27, M30, etc. Generally, the tightening of high-strength bolts should be first and then final tightening, and each step needs to have strict torque requirements. Constant torque wrench must be used for initial tightening and final tightening of large hexagon high strength bolts.
三、定扭矩电动扳手使用方法
3、 Usage of constant torque electric wrench
1、电源的连接
1. Connection of power supply
先将主机的三芯插头插入控制仪相应的插座上,然后将控制仪上的电源线接入电网。绿/黄双色芯线为接地线。
First, insert the three core plug of the host into the corresponding socket of the controller, and then connect the power line of the controller to the power grid. The green / yellow core wire is the grounding wire.
工作结束后,以相反方向拆卸。
After the work is finished, dismantle in the opposite direction.

2、螺栓的扭紧操作
2. Tightening operation of bolts
1)装上反力支架,并紧固螺钉。开动主机,使方头销孔与反力支架孔相对应,然后装入扳手套筒,插上销钉,并用橡胶圈固定。
1) Install the reaction support and tighten the screws. Start the main engine to make the square head pin hole correspond to the reaction support hole, then install the wrench socket, insert the pin, and fix it with rubber ring.
2)将控制仪的扭矩旋扭调到所需扭矩值,将主机正反开关拨到正转位置,把扳手套筒套在螺纹连接件的六方上。
2) Adjust the torque of the controller to the required torque value, turn the positive and negative switch of the host to the forward rotation position, and put the wrench socket on the hexagon of the threaded connector.
3)按下电源开关,扳手启动。当反力支架力臂靠牢支点时(支点可以是邻近的一只螺栓或其他可做支点的位置)螺栓开始拧紧。当螺栓扭矩达到预定扭矩时,扳手自动停止,紧固完成,放开电源开关,进行下一只螺栓的紧固工作。
3) Press the power switch to start the wrench. When the force arm of the reaction support is firmly against the fulcrum (the fulcrum can be a nearby bolt or other fulcrum position), the bolt begins to tighten. When the bolt torque reaches the predetermined torque, the wrench will stop automatically and the tightening is completed. Release the power switch to tighten the next bolt.
4)扳手自动停止后,靠反力支架的弹性形变力,使支架力臂自动脱离支点,取下扳手。如力臂不能脱离支点时,可拨动正反开关,点动电源开关,扳手即可取下。
4) After the wrench stops automatically, the arm of the bracket will automatically break away from the fulcrum by the elastic deformation force of the reaction support, and then the wrench can be removed. If the force arm can not be separated from the fulcrum, the positive and negative switch can be turned, and the power switch can be touched to remove the wrench.
3、螺栓的拆卸操作
3. Bolt removal
扳手在拆卸螺栓(反转)时,其操作方法与拧紧操作相同,只是将正反开关拨到反转位置,螺栓卸松后防开电源开关。
When the wrench is removing the bolt (reversing), the operation method is the same as that of tightening, but the positive and negative switch is turned to the reverse position, and the power switch is not opened after the bolt is loosened.
4、扭矩的选择与调节
4. Selection and adjustment of torque
1)用户可在100---3500Nm的范围内任意选择相应规格的电动扳手。
1) The user can choose the electric wrench of corresponding specifications in the range of 100-3500nm.
2)控制仪面板上有“扭矩调节”旋扭,刻有0—100刻度值,用以调节扭矩。
2) There is a "torque adjustment" knob on the panel of the controller, which is engraved with 0-100 scale value to adjust the torque.
3)调节方法:产品出厂带有扭矩测试数据卡片,供用户标定时参考,用户可根据所需扭矩选择某一刻度值,按照拧紧螺栓的操作方法,扭紧螺栓。用测力扳手或其他测力仪器测出螺栓的实际扭矩值,若扭矩值偏高,将旋扭向低刻度调节;若扭矩值偏低,则向高刻度值调节,反复几次既可达到所需精确扭矩值。
3) Adjustment method: the product is provided with torque test data card for users' reference during calibration. The user can select a calibration value according to the required torque and tighten the bolt according to the operation method of tightening the bolt. The actual torque value of the bolt is measured with a force measuring wrench or other force measuring instruments. If the torque value is too high, adjust the torque to the low scale; if the torque value is low, adjust it to the high scale value. Repeat several times to achieve the required accurate torque value.
