Consider adding: Sunset Yellow Lemon Yellow as appropriate. (Not for now. After gaining experience, I feel like adjusting the color before making it.) The production steps are as follows:

高強螺栓作為鋼結(jié)構(gòu)節(jié)點連接中常用的部件,在鋼結(jié)構(gòu)中起到非常重要作用。高強螺栓主要由扭剪型高強螺栓和大六角螺栓之分。高強螺栓采用電動扳手來緊固。

High strength bolts, as commonly used components in steel structure node connections, play a very important role in steel structures. High strength bolts are mainly divided into torsion shear type high strength bolts and large hexagonal bolts. High strength bolts are tightened using an electric wrench.

認識螺栓

Understanding bolts

由頭部和螺桿(帶有外螺紋的圓柱體)兩部分組成的一類緊固件。

A type of fastener consisting of a head and a screw (a cylindrical body with external threads).

扭剪型高強螺栓

大六角螺栓

Large hexagonal bolt

螺栓的等級

Grade of bolts

性能等級分3.6、4.6、4.8、5.6、6.8、8.8、9.8、10.9、12.9等10余個等級。

The performance level is divided into more than 10 levels, including 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc.

①高強度螺栓:指的是性能等級為8.8級及以上的螺栓,其材質(zhì)為低碳合金鋼或中碳鋼并經(jīng)熱處理(淬火、回火)。

① High strength bolt: refers to a bolt with a performance grade of 8.8 or above, made of low-carbon alloy steel or medium carbon steel and subjected to heat treatment (quenching, tempering).

②普通螺栓:其余通稱普通螺栓,可分為精制螺栓(A、B級:5.6或8.8)和粗制螺栓(C級),性能等級一般為4.6或4.8。

② Ordinary bolts: commonly referred to as ordinary bolts, can be divided into refined bolts (A, B grade: 5.6 or 8.8) and rough bolts (C grade), with a performance level generally of 4.6 or 4.8.

螺栓的連接

Bolt connection

螺栓與螺母配合,用于緊固連接兩個帶有通孔的元件,屬于可拆卸連接。

The bolt and nut are used to tighten and connect two components with through holes, and belong to detachable connections.

螺栓連接的工作原理

Working principle of bolted connections

胡可定律:固體材料受力之后,材料中的應(yīng)力與應(yīng)變(單位變形量)之間成線性關(guān)系。

Hooke's Law: After a solid material is subjected to a force, there is a linear relationship between the stress and strain (unit deformation) in the material.

漢普電動扳手的應(yīng)用

The application of Hanpu electric wrench

電動扭剪扳手主要用于緊固高強度扭剪螺栓,并且在緊固完成后將剪斷的梅花頭保留在套筒內(nèi)部不掉落,隨后扣動扳機將梅花頭彈出。

The electric shear wrench is mainly used to tighten high-strength shear bolts, and after tightening, the cut plum blossom head is kept inside the sleeve without falling off, and then the trigger is pulled to pop the plum blossom head out.
