Anti-theft door formed by bending and stamping and preparation method thereof

Abstract

The invention discloses an anti-theft door formed by bending and stamping and a preparation method thereof, and belongs to the technical field of theft prevention. The anti-theft door comprises a front panel, a door core, a rear panel and a reinforced side door plate, wherein the door core comprises a front door core plate, a topological framework and a rear door core plate; the front door core plate and the rear door core plate adopt an integral forming process; and the topological framework is prepared by adopting a powder forming technique. The anti-theft door has the following advantages that (1) a finite element analysis technique is adopted, so that the strength is guaranteed, additionally, the volume and thickness of the framework is optimized, and the production difficulty and cost are reduced; (2) the framework is prepared by adopting a hot isostatic pressing technique, so that different powder can be selected as required so as to realize different strength effects; and (3) the front door core plate and the rear door core plate are prepared by adopting a bending and stamping forming technique, and the procedure of secondary processing is reduced and the timeliness of preparation is improved by utilizing the combination of a bending part and the framework.

Description

technical field [0001] The invention belongs to the field of anti-theft technology, in particular to a bending and stamping-formed anti-theft door and a preparation method thereof. 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 hand drills within 15 minutes or a 615 square centimeter 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. Anti-theft doors can be made of different materials, but only those do...
