Panel stamping and bending process of control cabinet

Abstract

The invention discloses a panel stamping and bending process of a control cabinet. The panel stamping and bending process comprises the following steps of: regulating a gap between an upper blade and a lower blade of a plate shearing machine according to the quality and the thickness of a plate material; cutting and blanking according to the length and the width of the designed plate material; programming according to an unfolded picture of an appearance of a product, drawing the unfolded picture of the appearance of the product and determining selected moulds by adopting a numerically controlled turret punch press; stamping according to the thickness, the quality and the length of the plate material; bending the plate material by a bending machine, selecting a crank arm type convex mould, enabling a sliding block to drive a clamping block and the sliding block to move longitudinally due to the connection of the clamping block and the sliding block so as to realize the bending movement of an upper mould; regulating the clamping block through a regulating mould to regulate a horizontal position of a lower mould and ensure that the lower mould and the upper mould are parallel; and correcting by a hammer planishing method. The principle of hammering parts of the plate material comprises the following steps of: hammering the circumference of the plate material if the middle part of the plate material is wrinkled, and hammering the middle part of the plate material if the circumference of the plate material is wrinkled. The invention has the advantages of mainly reducing a lineation working procedure and the labor strength, and also has the certain realistic significance to guide the enterprise production.

Description

technical field [0001] The invention relates to a stamping and bending process of sheet metal, in particular to a stamping and bending process of a control cabinet panel. Background technique [0002] At present, the production process of the panel of the electrical control cabinet is: blanking - scribing - common punch punching - bending - shaping. The disadvantages are that the scribing accuracy is low, and the scribing operation is labor-intensive; the four sides of the bent sheet often have edges that are not on a straight line, and the bending arcs at both ends of the panel are not on the same bending line. The curvature after bending is inconsistent, which makes it difficult for the subsequent fitter to correct the shape, and the gap between the box body and the assembly is inconsistent. Contents of the invention [0003] The purpose of the present invention is to provide a control cabinet panel stamping and bending process with less production steps and low labor i...
