Punching device applied to field of automobile manufacturing

The invention discloses a punching device applied to the field of automobile manufacturing. The punching device comprises a base, a mounting seat is fixedly mounted at the top of the base, a die block is fixedly mounted on the mounting seat, and a material frame and a fixing block are fixedly mounted on the mounting seat. A pushing plate is driven by an air cylinder to push a workpiece to the position above the lower die block, a hydraulic cylinder is started to stretch out a piston rod, a sliding block is driven to move downwards, a second connecting rod pushes a tipping bucket to rotate to leave a mounting base, an upper die block and the lower die block are closed to punch the workpiece, the hydraulic cylinder is started to retract the piston rod, negative pressure is introduced into a negative pressure pipe to suck the workpiece, the sliding block drives the upper die block to suck the workpiece to move upwards, the sliding block moves upwards to pull the second connecting rod to drive the tipping bucket to rotate to the position below the upper die block, normal pressure is introduced into the negative pressure pipe, the workpiece falls into the inclined tipping bucket under the action of gravity and then falls into a collecting box, a punching process is completed, material putting and discharging of the workpiece are achieved through a mechanical mechanism, operation is simple, and working efficiency is improved.
