Semi-integral safety box and manufacturing method thereof

Abstract

The invention discloses a semi-integral safety box and a manufacturing method thereof. The semi-integral safety box comprises a box body, a box door, a door lock component and a hinge component. The hinge component is arranged on one side edge of the box door, and the box door is connected with the box body through the hinge component. The door lock component is arranged on the box door and matched with a lockhole in the box body. The box body comprises a left side plate, a right side plate, an upper side plate and a lower side plate which are formed integrally in a punching mode. The box body further comprises a rear side plate which is connected with the left side plate, the right side plate, the upper side plate and the lower side plate in a press fit mode. The semi-integral safety box is high in mechanical strength and security. Continuous punch forming is adopted for the manufacturing method, so that production efficiency is greatly improved, production cost is reduced, and surface quality is good.

Description

technical field [0001] The invention relates to a safe and a manufacturing method thereof. In particular, it relates to a semi-integral safe and a manufacturing method thereof. Background technique [0002] Safes on the market are mainly divided into fire safes and theftproof safes, antimagnetic safes, fire antimagnetic safes and the fire theftproof safes and the fire theftproof safes and so on according to their functions. Such as figure 2 As shown, the general process of safe making in the prior art is as follows: [0003] Steel plate blanking—>sheet forming—>welding processing—>surface treatment—>assembly—>general inspection—>packaging—>warehousing. [0004] The first process is to cut the purchased large steel plate into the required small plates through the shearing machine, so as to facilitate the next process processing. [0005] Sheet metal forming: pass small plates through various punches, molds, bending machines and other machinery and equ...

AI Technical Summary

Problems solved by technology

[0011] Yet what the box body forming technology of existing safe adopts is that five steel plates are stamped and formed respectively, and then welded into the shape of the safe box body, its defect is: production efficiency is low, and because the side panel of the box body of safe box, The bottom panel, front panel, and rear panel are all welded to form the safe box body. There is a large welding stress during welding, which often leads to deformation of the safe box body and affects the appearance; moreover, there are often welding defects at the weld seam, which leads to the failure of the safe box. The overall strength of the cabinet is reduced, and the welds are also prone to corrosion, which affects the service life of the safe
