Abstract

The invention relates to a punching method for a sheet metal part. According to the punching method for the sheet metal part, a punching head driven by a punching driving device, a clamping device driven by a turning motor and a supporting device driven by a pushing air cylinder are included; the punching driving device, the turning motor and the pushing air cylinder are all connected with a controller; and during punching, a machined part is controlled by the controller to turn, so that punching is achieved twice for both sides. The turning type punching method is adopted, punching of thick sheet metal parts is achieved, the punching resistance is small, and the quality of holes is high.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to a sheet metal punching machine. Background technique [0002] Existing punching devices or punching machines all include a frame, a bottom mold fixed on the frame, an upper template that moves up and down relative to the frame, and a punch corresponding to the bottom mold is fixed on the upper template. , the upper template is connected with the oil cylinder or cylinder that drives it to move up and down. Driven by the oil cylinder or air cylinder, the upper template drives the punch to move up and down relative to the bottom die, so as to punch out the required holes on the workpiece between the punch and the bottom die. The above-mentioned punching device or punching machine adopts a one-time punching method to punch holes, and its disadvantages are: only thin plates can be punched, and there are many burrs on the edge of the hole after punching, and the hole pr...
