Embodiment Construction
[0007] The metal billet is crushed by a roller, cold-rolled by a cold rolling mill to form a metal steel plate, the metal plate is annealed at a high temperature, and the leveler is leveled into a flat metal steel strip, and then the flat metal steel strip is opened by a belt unwinding machine. For the finished flat metal steel strip that needs width, punch out holes and openings of different shapes, sizes, and spacing required on the finished flat metal steel strip with a punching machine, and then gradually deform and shape it through the mold, weld it with a welding machine and grind it with a grinding machine It is a finished porous open circular tube, and then the finished porous open circular tube is extruded through a die to form a porous open square tube, a porous open rectangular tube or a porous open special-shaped tube.

Abstract
The multi perforated metal tube is made by crushing the metal blank, cold rolling and strap opening to form the metal plate, punching holes on the metal plate, welding perforated round tubes through mold locating, grinding the round tube to get the final product, and finally compressing the got round tube to multi perforated square tube, rectangular tube or shape tube through molds. It is easy in process, low in cost, high in efficiency, good in material quality, strong in structure, less in welding joint, high in material recovery rate, low in mold scrap and strong in repairing.
Description
technical field [0001] The invention relates to a preparation process of a metal pipe, in particular to a preparation process of a metal pipe with a porous opening. Background technique [0002] Metal pipes with porous openings are mostly used in daily life, and are often used in coffee tables, dining tables, beds, shoe racks, shelves, fitness equipment, stairs, guardrails, protective nets, doors, carports, grids and billboards, etc. At present, the production of metal pipes with porous openings is the secondary processing of finished round pipes, square pipes, rectangular pipes, and special-shaped pipes. The mouth is assembled and combined to form the pattern, and then welding, grinding, and surface treatment are completed to complete the finished metal pipe engineering product. The existing process of producing metal pipes with porous openings is to punch holes and punch holes on the pipes, so that the mold scrap rate is high and the repairing force is poor, which brings ...
