Computer case punch forming device and using method thereof

Abstract

The invention discloses a computer case punch forming device and a using method thereof, relates to the technical field of punching devices, and aims to solve the problem that after punching of an upper die is finished, a case plate on a lower die is easily lifted up in the upward moving process. The device specifically comprises a mounting frame, a warning lamp is arranged on the outer wall of the top of the mounting frame, a hydraulic push rod is arranged on the inner wall of the top of the mounting frame, a stand column is arranged on the inner wall of the bottom of the mounting frame, and a control panel is arranged on the outer wall of one side of the stand column. The using method of the device specifically comprises the steps that a plate is placed on an electric conveying plate, and the electric conveying plate is controlled by the control panel to drive the plate to one side of a supporting table. An extrusion block, an air bag, a first air guide pipe, a second air valve and an adsorption plate are arranged, after the plate is punched, a pressing plate moves upwards through the hydraulic push rod to be reset, at the moment, a connecting rod pushes the extrusion block to move upwards, and therefore the air bag is stretched.

Description

technical field [0001] The invention relates to the technical field of punching devices, in particular to a punching forming device for a computer case and a method for using the same. Background technique [0002] Among the components of the computer, the computer case is a very important part of the computer accessories. Its main function is to place and fix various computer accessories, and play a role of support and protection. In addition, the computer case plays an important role in shielding electromagnetic radiation. The chassis generally includes a shell, a bracket, various switches on the panel, indicator lights, etc. The shell is made of steel plate and plastic, with high hardness, mainly to protect the internal components of the chassis. During the production process of the chassis, a stamping process is performed to process the holes on the surface of the chassis.
