Servo punching machine punching strength adjusting mechanism and using method thereof

Abstract

The invention relates to the technical field of servo punching machines, in particular to a servo punching machine punching strength adjusting mechanism and a using method thereof. The servo punching machine punching strength adjusting mechanism comprises a punching machine body, wherein an upper punching block is arranged at the position, corresponding to the upper portion of a workbench, of the punching machine body, a blocking module is fixedly connected with the top face of the workbench of the punching machine body, and comprises a fixing plate, connecting grooves are formed in both sides of the top face of the fixing plate, and connecting rods are slidingly connected with the inner side faces of the connecting grooves. According to the servo punching machine punching strength adjusting mechanism and the using method thereof, a baffle is arranged through connecting rods, when the upper punching block drives an upper die to impact downwards, a driving rod can drive the baffle to move through the connecting rods, and meanwhile, a round block can slide along an arc-shaped rail, so that the baffle moves upwards to block the positions of the upper die and a lower die, the situation that a worker stretches hands into the punching machine body is avoided, meanwhile, when circuit failures occur, the worker can be blocked, the stability of the baffle is high, improvement of the safety coefficient of a punching machine is facilitated, and the personal safety of the worker can be guaranteed conveniently.

Description

technical field [0001] The invention relates to the technical field of servo punches, in particular to a punching strength adjustment mechanism of a servo punch and a method for using the same. Background technique [0002] Servo punch press is a stamping press driven and controlled by a servo motor. It is suitable for production lines such as stretching, punching, bending, cold forging, and embossing, as well as test die punching machines. The servo punching machine uses a servo motor as a direct power source. Through the screw, The driving force generated by the motor is converted into the linear motion of the slider by means of crank connecting rod and toggle rod, so as to stamp the workpiece. The stamping strength adjustment mechanism can buffer the upper die to adjust the impact strength of the upper die on the workpiece as required. [0003] When the punching strength adjustment mechanism of the existing servo punch press is in use, because the upper die of the servo ...

AI Technical Summary

Problems solved by technology

[0003] When the punching strength adjustment mechanism of the existing servo punch press is in use, because the upper die of the servo punch press has a relatively large impact force when it moves downward, it is dangerous for workers to use the servo punch press. The existing servo punch press is usually equipped with a light When the servo press is working, if the worker puts his hand into the servo press, the worker's hand can block the light curtain to stop the servo press, but the light curtain needs to be connected to the internal circuit of the servo press. If a circuit failure occurs, The light curtain does not stop the servo press, which is prone to danger and is not conducive to ensuring the personal safety of workers
