Edge turning forming process of stainless steel skirt guard panel of escalator

Abstract

The invention relates to an edge turning forming process of a stainless steel skirt guard panel of an escalator, and belongs to the technical field of elevator part manufacturing. The edge turning forming process includes the following steps of firstly, conducting panel shearing and punching, wherein a stainless steel panel is sheared and punched; secondly, conducting pressing and bending, wherein by means of a die plate of a hollow structure, one side of a profile is embedded in the hollow structure of the die plate, a hydraulic head conducts downward pressing so as to punch the other side of the skirt guard panel profile, and the skirt guard panel profile can form a protruding structure; thirdly, conducting bending, wherein the stainless steel skirt guard panel can be obtained by conducting cold bending operation on the protruding structure of the skirt guard plate panel on a bending machine. By means of the forming process, forming can be conducted in place at a time, the deformation amount is small, rigidity is high, and the work efficiency is high; no burr or rough selvedge is generated on the outer edge of an obtained product, and the risk that passengers and objects are scratched is avoided. The product obtained according to the process can be applied to medium and high-end market of escalators at home and abroad.

Description

technical field [0001] The invention relates to the technical field of elevator component manufacturing, and more specifically, the invention relates to a flanging forming process for an escalator stainless steel apron plate. Background technique [0002] The steps or treads of the escalator are equipped with an apron system on both sides to keep passengers and goods safe. The apron system is realized with many apron connections. The currently widely used apron board is a flat plate structure, which is weak in rigidity and requires more reinforcements to make up for it, and has burrs or burrs exposed outside, which pose a safety hazard to passengers and objects. The traditional stainless steel apron plate is mainly formed by single-roll pressing, which often has a small pressing pressure and cannot be formed at one time. big. Once a problem occurs, it will increase the cost and cause a lot of waste of manpower, material and financial resources. Contents of the invention...
