Embodiment 1

[0013] Example 1 as figure 1 As shown, it is a special-shaped channel steel, the wall thickness of flanges 1, 2 and web 3 is equal, the height of the flange is 1 / 2 of the length of the web, and the flange of the channel steel is straight.

Embodiment 2

[0014] Example 2 as figure 2 As shown, it is special-shaped channel steel with external bevel angle, the wall thickness of flange 1, 2 and web plate 3 is equal, the flange height is half of the length of the web plate, and the top outer side of the flange has an external bevel angle 4, so The outer bevel is smoothly transitioned to the top surface at 1 / 10 of the upper outer surface of the channel steel flange, and the angle of the outer bevel 4 is 20-40 degrees.

[0015] When the two-shaped steel is butted and used to make the axle tube of the trailer, there is no need to cut the welding incision, which reduces the processing procedure, effectively saves metal materials, and improves work efficiency.

[0016] The dimensions of the above two types of steel are:

[0017] Example 1: 150×75×16 for the production of 13-15t trailer axle tubes

[0018] Example 2 150×75×16×28 for the production of 13-15t trailer axle tubes

Abstract

A U-shaped steel used for the tubular axle of trailer is disclosed. Its manufacture technology includes such steps as providing raw material, heating, rolling, cooling, and finishing. It can improve the structure and strength of tubular axle.

Description

technical field [0001] The invention relates to a trailer shaft tubular steel and a processing method thereof, and belongs to the technical field of special steel profiles for vehicle manufacturing. Background technique [0002] The trailer shaft tube is the load-bearing structural part of the rear axle of the heavy-duty trailer. Its processing technology is to cut the steel plate, trim it, punch it, and grind it into a C-shaped shaft piece. Then two pieces of C-shaft pieces are cut into sections, polished and welded, and relatively fastened and welded to form a tubular trailer axle tube. The production process is complicated, the utilization rate of steel is not high, and bending stress is easily formed at the fillet during the stamping process, which is not conducive to the load bearing of the axle, and the cost of processing and manufacturing the axle tube is high. Contents of the invention [0003] In order to change the backward processing technology of the current h...
