Problems solved by technology

However, these methods have great deficiencies in terms of quality and benefit: the use of flower cutting bending, because only part of the cutting is used, resulting in no arc at right angles after the cutting part is bent, the overall bending style is not uniform, and the quality and craftsmanship are poor ;Using combined welding of steel plates, the entire step right angle has no arc after forming, and there are many edges and corners, so the quality of the steel ladder steps produced is defective; and the method of using lever knuckles or jack pressing, although generally can achieve the quality of the steel ladder steps. Requirements, but it requires a lot of manpower and labor intensity, resulting in low production efficiency

Embodiment

[0041] According to the following steps, the material plate 3 is bent to obtain an "N"-shaped steel ladder step, and the material plate 3 is a checkered steel plate.

[0042] A. Make two fixing plates and backing plate 4, the fixing plates include a first fixing plate 21 and a second fixing plate 22. The first fixing plate 21 and the second fixing plate 22 have the same fixing plate height h, and both adopt channel steel.

[0043] B. The first fixed plate 21 and the second fixed plate 22 are fixedly installed on the backing plate 4, there is a gap between the first fixed plate 21 and the second fixed plate 22; the first fixed plate 21 and the second fixed plate The two fixed plates 22 have the same fixed plate length L3, and the material plate 3 is installed in the gap between the first fixed plate 21 and the second fixed plate 22, and the material plate length L3 of the material plate 3≤fixed plate Length L2, one end of the material plate 3 in the gap is a folded edge 31, th...

Abstract

The invention discloses a method for a veneer reeling machine pressed-steel ladder rung. The method can improve the quality of the pressed-steel ladder rung and reduce corner angles of the pressed-steel ladder rung. The method includes the following steps that a first fixing plate and a second fixing plate are manufactured and installed on a base plate, a material plate is installed between the first fixing plate and the second fixing plate on the base plate, the position of the material plate is adjusted, an angle alpha is formed between the material plate and the base plate, then the material plate is sent into a veneer reeling machine, a bent edge of the material plate is bent for the angle alpha, the material plate is taken out, the bent edge is vertically installed between the first fixing plate and the second fixing plate, a blocking plate is added between the first fixing plate and the second fixing plate so as to enable the bent edge to be clamped through the first fixing plate and the second fixing plate, the material plate is sent into the veneer reeling machine once again to be bent for the second time to enable the bent edge to be vertical to the material plate, the material plate is taken out and serves as one end to be installed on the base plate, the steps are repeated, and thus an N-shaped pressed-steel ladder rung or a Z-shaped pressed-steel ladder rung is obtained. By the adoption of the method, labor investment can be reduced, work efficiency is improved, and production cost is saved.

Description

technical field [0001] The present invention relates to a plate rolling method, in particular to a method for pressing steel ladder steps by a plate rolling machine. Background technique [0002] Known: steel ladders for industrial buildings are generally produced and installed in large quantities on-site when the main body of the project is completed to the middle and late stages. Steel ladder steps are an important part of building steel ladders. According to the needs of various construction projects, steel ladder steps generally have two types: steel grating plate and checkered steel plate. The steps of the patterned steel ladder are in the shape of "Z" or "N", and the front and rear of the steps are composed of two right angles with arcs. Patterned steel ladder steps are generally made by bending on-site after blanking patterned steel plates. [0003] In the process of making patterned steel ladder steps, the traditional two right-angle bending and manufacturing meth...
