Process for machining boundary beam of vehicle carrying plate

Abstract

The invention relates to a process for machining a boundary beam of a vehicle carrying plate. The process comprises the following machining steps of (1) shearing a galvanized steel sheet through a plate shearing machine, punching the sheared galvanized steel sheet through a turret punch press to obtain a workpiece, forming the end of the workpiece in a stamping mode to obtained the workpiece with the end subjected to stamping formation, and performing bending formation on the end of the workpiece with the end subjected to stamping formation through a bending machine to obtain a beam body; (2) shearing a cold-roll steel sheet through the plate shearing machine to obtain a welding connector and an inclined plate which are integrally formed, performing press formation on the welding connector and the inclined plate through a die by means of a pressing machine, performing welding, and spraying caution paint on the surfaces of the welding connector and the inclined plate to obtain an end head; (3) welding the end head to the beam body through a spot welding machine to obtain the boundary beam of the vehicle carrying plate. According to the process, the principle of electric resistance welding is adopted in the spot welding machine, electric resistance welding is completed instantly due to the small contact area of the workpiece and the spot welding machine, and the galvanized sheet can be welded while the galvanized surface is not damaged.

Description

technical field [0001] The invention relates to a process for processing a side beam of a vehicle-carrying plate. Background technique [0002] Lifting and traversing mechanical parking equipment is widely used in public parking places. The vehicle-carrying board responsible for parking vehicles in the equipment is an essential part, and the lintel of the vehicle-carrying board is an important part of the vehicle-carrying board. [0003] The traditional processing process of the side beam of the vehicle-carrying plate is: use cold-rolled steel plate blanking, folding forming, welding, galvanizing, and finished product. Among them, the galvanizing process is generally outsourced production, the general cycle is long, and the quality of the manufacturers varies, so the construction period and quality cannot be guaranteed well. In addition, this process also pollutes the environment. Since the galvanized sheet will destroy the galvanized surface during conventional welding and...

Among them, the galvanizing process is generally outsourced production, the general cycle is long, and the quality of manufacturers varies, so the construction period and quality cannot be well guaranteed. In addition, this process also pollutes the environment.

Since the galvanized sheet will destroy the galvanized surface during conventional welding and the surface will turn black, so the traditional processing technology of the side beam can only be galvanized after welding
