Automatic blanking die of sheet metal part

Abstract

The invention discloses an automatic blanking die of a sheet metal part, and belongs to the technical field of sheet metal part processing equipment. The automatic blanking die comprises a lower die plate with a female die, an upper die plate and guide columns, a control table is arranged on one side of the automatic blanking die, and a motor and an oil pressure gauge are arranged on the control table. A hydraulic oil cylinder is arranged on the upper surface of the upper die plate, and an oil inlet pipe and an oil outlet pipe are arranged on one side of the hydraulic oil cylinder. The hydraulic oil cylinder is connected with the motor and the oil pressure gauge through oil pipes. A male die is arranged on the upper die plate, the upper end of the male die is connected with the guide rod of the hydraulic oil cylinder, and the lower end face of the male die is conical. The conical male die is adopted in the automatic blanking die, and the sheet metal part can be blanked fast and effectively. In addition, the motor is adopted to drive the hydraulic oil cylinder to push the male die vertically, the phenomenon that output force is insufficient can be avoided, the operating motion of the oil cylinder is smoother than that of an air cylinder, and the quality of the sheet metal part can be better.

Description

technical field [0001] The invention belongs to the technical field of sheet metal parts processing equipment, in particular to an automatic punching die for sheet metal parts. Background technique [0002] Sheet metal parts are products processed by sheet metal technology. They have the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. Instruments and other fields have been widely used. For example, in computer cases, mobile phones, and MP3 players, sheet metal parts are an indispensable part. Sheet metal parts are fabricated by filament power winding, laser cutting, heavy machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, water jet cutting, precision welding . Among them, the cutting of sheet metal parts is especially common. [0003] In the prior art, the cutting of sheet metal parts ...

AI Technical Summary

Problems solved by technology

[0006] In view of the fact that the existing punching dies for sheet metal parts cannot achieve high-quality and high-efficiency punching, in addition, cylinders are generally used to realize the up and down movement of punches, but the cylinders have shortcomings such as insufficient output force and unstable movements, which will lead to sheet metal parts low quality or even scrapped parts, the present invention provides an automatic blanking die for sheet metal parts, which adopts a tapered punch, which can quickly and effectively realize the blanking of sheet metal parts, and uses a motor to drive a hydraulic cylinder to realize The up and down push of the punch can avoid the phenomenon of insufficient output force, and the operation of the oil cylinder is more stable than that of the cylinder, so that better quality sheet metal parts can be obtained
