Manufacturing process of anti-theft door adopting outer-aluminum inner-steel process

Abstract

The invention discloses a manufacturing process of an anti-theft door adopting an outer-aluminum inner-steel process. The manufacturing process comprises the following steps that S1, a door body and a door frame are cut; S2, a cut plate is subjected to numerical control automatic slotting; S3, the slotted plate is taken to a numerical control press to be machined and punched; S4, door surface bending is carried out; S5, the door face is bent and formed, and then welding is carried out; S6, front and rear plates of the door body are glued, the front and rear plates of the door body are brushed with a foaming agent and filled with fireproof rock wool, and the front and rear parts of the door body are leveled through a leveling machine; S7, the door body is subjected to paint treatment; S8, bending and corner cutting are carried out on the door frame, then electric welding forming is carried out, and then polishing and paint treatment are carried out; S9, an aluminum plate is selected, then edge milling treatment is carried out, and meanwhile auxiliary materials of the door are made; and S10, the door body and the door frame are combined together, a lock is installed, and finally debugging is completed. The manufacturing process is simple in structure and simpler and more convenient to assemble, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of anti-theft doors, in particular to a manufacturing process of an anti-theft door with an outer aluminum inner steel process. Background technique [0002] The full name of anti-theft door is "anti-theft safety door". It has both anti-theft and safety performance. According to the "General Technical Conditions for Anti-theft Safety Doors", a qualified anti-theft door cannot be pried open by ordinary hand tools such as chisels, screwdrivers, crowbars, and portable electric tools such as electric hand drills within 15 minutes or a 615 square millimeter hole can be opened on the door leaf. opening, or a 38 mm2 opening within a semicircle of 150 mm2 at the locking point. And the lock used on the security door must be the special lock for the security door with anti-drilling function after passing the test by the Testing Center of the Ministry of Public Security. Existing anti-theft door technology has follo...

AI Technical Summary

Problems solved by technology

[0003] First, there are generally two types of craft structures on the market: outer aluminum boards and inner wood boards and outer aluminum and inner aluminum. The inner structure is relatively simple, surrounded by existing aluminum profile clips, which are complicated to assemble and difficult to control in size Higher cost, longer construction period and relatively higher price;

[0004] Second, because the inner panel is made of wood veneer, the production process is relatively complicated, and many of them have to be processed externally, which prolongs the production period, increases the production cost, and the price is relatively high;

[0005] Third, due to technological limitations, many similar products on the market do not have anti-theft and fire protection functions
