Rack box bottom side beam, manufacturing method thereof and method for manufacturing rack box

Abstract

Disclosed are a rack box bottom side beam, a manufacturing method of the rack box bottom side beam and a method for manufacturing a rack box. The manufacturing method of the rack box bottom side beam comprises the steps that a web in a ripple shape in the longitudinal direction is manufactured; an upper wing plate, a lower wing plate and the web of the bottom side beam are placed on a supporting table, the web is placed between the upper wing plate and the lower wing plate for locating to form a bottom side beam primary blank, and the web, the upper wing plate and the lower wing plate are made to be in an H shape; a plurality of oil cylinders on the supporting table are fixed to abut against the lower wing plate, the bottom side beam primary blank is made to be bent towards the upper wing plate from the lower wing plate until the upper wing plate is tightly attached to a plurality of check blocks fixedly arranged on the supporting table, the check blocks are in a first preset camber, and therefore the bottom side beam primary blank is made to reach the first preset camber; the upper wing plate and the lower wing plate are respectively connected to the web, and therefore the rack box bottom side beam with a second preset camber is manufactured. The web is made to be of a ripple structure so as to increase the elasticity of the web, the bottom side beam primary blank is made to be bent to form the camber after the two sides of the bottom side beam primary blank are clamped, and therefore production efficiency and product quality are improved, and cost is lowered.

Description

technical field [0001] The invention relates to a container, in particular to a platform box bottom side beam and a manufacturing method thereof, and a manufacturing method of the platform box. Background technique [0002] In the field of containers, bench boxes are widely used because of their convenient loading and unloading and heavy load; bench boxes can generally be divided into folded-end bench boxes and fixed-end bench boxes. [0003] Such as figure 1 As shown, the components of a general folding container mainly include an underframe 2' and end walls 1' arranged at both ends of the underframe platform; figure 2 As shown, the underframe 2' includes bottom side beams 21' located on both sides thereof, a bottom cross beam 22' fixedly connected laterally between the two bottom side beams, and end beam bodies 23' arranged at both ends thereof. [0004] In the prior art, in order to increase loading capacity and durability, the bottom side beam is usually designed to h...

AI Technical Summary

Problems solved by technology

Therefore, there are more scraps produced in the production of webs, the efficiency of making webs is low, and the cost of web production is relatively high

In addition, because the upper and lower wings of the bottom side beam of the I-shaped section are thick and wide, and the web is thin, the structural stability of the bottom side beam section is poor, and the web is easy to lose stability and cause damage to the bottom side beam
