Pneumatic stamping device for hole machining of sheet metal part

Abstract

The invention discloses a pneumatic stamping device for hole machining of a sheet metal part. The pneumatic stamping device comprises a stamping working table, an upper die holder, a guide column, a lower die holder, a stamping drive block, a cylinder, a hydraulic pressure cylinder, a forming male die, a forming female die, a male die fixing block, a female die positioning block and a product pick-place mechanism. The lower die holder is arranged on the stamping working table. The position of the upper die holder and the position of the lower die holder are vertically corresponding to each other. The upper die holder and the lower die holder are connected through the guide column. The upper end of the stamping drive block is connected with the cylinder which is fixed to the upper die holder. The hydraulic pressure cylinder is arranged on the right side of the cylinder. The stamping working table is arranged on the lower die holder. The forming female die is fixed to the lower die holder through the female die positioning block. The product pick-place mechanism is placed on the right side of the lower die holder. The forming male die and the forming female die makes contact to complete hole piercing of the sheet metal part, machining is completed through one procedure, the machining size precision is high, and work efficiency is greatly improved; meanwhile, materials are automatically picked and placed through the product pick-place mechanism, and the potential safety hazards of manual material picking and placing can be avoided.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a pneumatic stamping device for hole processing of sheet metal parts. Background technique [0002] In the sheet metal parts production and processing industry, it is often necessary to perform stamping processing on sheet metal parts. Stamping processing uses the power of conventional or special stamping equipment to directly deform the sheet metal in the mold to obtain a certain shape. Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Due to the use of precision molds, the precision of the workpiece can reach micron level, and the repeatability is high and the specifications are consistent. , can punch out certain shapes such as holes, bosses, etc. However, most of the existing stamping devices first carry out bulging and punching processing on the workpiece, and then carry out the punching process aft...

[0002] In the sheet metal parts production and processing industry, it is often necessary to perform stamping processing on sheet metal parts. Stamping processing uses the power of conventional or special stamping equipment to directly deform the sheet metal in the mold to obtain a certain shape. Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Due to the use of precision molds, the precision of the workpiece can reach micron level, and the repeatability is high and the specifications are consistent. , can punch out certain shapes such as holes, bosses, etc. However, most of the existing stamping devices first carry out bulging and punching processing on the workpiece, and then carry out the punching process after the bulging, and the size of the punching process is easily swollen. The impact of the shape, resulting in unstable punching size
