Problems solved by technology

The punching shape of such a punching machine is determined by the template on the slider. Although the crankshaft drives the slider to punch out the hole, but such a punching machine does not have a lower die, and the accuracy of punching out the hole cannot be guaranteed.
In addition, when the profile to be punched is driven forward by the main machine, the existing punch is only suitable for the forward speed of the profile. If it is changed to another profile, when the forward speed changes during the punching process, The current punching machine cannot be applied

Abstract

The invention relates to a double-crank automatic fast punching machine. The upper die is provided with a first shaft hole, the lower die is provided with a second shaft hole, and the eccentric end of the upper crankshaft extends into the first shaft hole on the upper die. The center is close to the hole wall of the shaft hole, the eccentric end of the lower crankshaft extends into the second shaft hole on the lower mold and is close to the wall of the shaft hole, and the lower end surface of the upper mold is provided with a first stepped hole , the lower end surface of the lower mold is provided with a second step hole, and the guide plate is provided with a through hole, one end of the guide post extends into the step hole on the upper die, and the other end of the guide post extends through the through hole on the guide plate. into the step hole on the lower die, and the first spring and the second spring are sleeved on the guide post respectively. The present invention drives the upper mold and the lower mold to work synchronously in the way of double crankshafts, so that the punching precision is effectively guaranteed.

Description

technical field [0001] The invention relates to a punching device, in particular to a double-crank automatic fast punching machine and a control method thereof. Background technique [0002] Punch press is a common equipment in machining, which is used in many fields. The punching machine used for punching coiled plates in the prior art generally includes a driving mechanism, a stamping mechanism and a feeding mechanism. The driving mechanism is composed of a motor, a main shaft, a driving gear, a driven gear and a crankshaft. The main shaft and the crankshaft are fixed on the machine On the frame, the main shaft is driven by the motor, the driving gear and the driven gear are respectively connected to the main shaft and the crankshaft, and the slider in the stamping mechanism is connected to the crankshaft through a crankshaft connecting rod, which is connected to the middle part. The punching shape of such a punching machine is determined by the template on the slider. A...
