Its purpose through this kind of stability that sets up increase stamping device, and then the difficult condition of empting takes place at the in-process that punches a hole.

Further, a stabilizer bar is fixedly connected between the support plate and the fixing plate. The purpose is that the stability of the stamping device can be further increased by means of this arrangement.

Further, the top of terrace die is equipped with two horizontal through-holes, and equal threaded connection has the threaded rod in two through-holes, the threaded hole threaded connection of one end and the second division board of threaded rod, the other end and the screw hole fixed connection on the limiting plate. The purpose is to facilitate the mounting and dismounting of the male die by means of such an arrangement.

Furthermore, also be equipped with two horizontal through-holes on the die, equal threaded connection has the threaded rod in two through-holes too, the threaded rod's one end and the screw hole threaded connection of first division board, the other end and the screw hole fixed connection on the fixed plate. Its purpose is, through the installation of this kind of setting be convenient for install and dismantle the die.

Furthermore, every threaded rod connected with the fixed plate and the limiting plate in a threaded mode extends to the outside of the fixed plate and the outside of the limiting plate and is connected with a fixing cap in a threaded mode. Its purpose prevents through the locking cap that the threaded rod lateral shifting from, leads to terrace die or die to drop.

Further, the motor is fixedly connected to the top of the base, a cavity is reserved in the inner top of the base, an output shaft of the motor penetrates through the base and is located in the cavity, an avoiding opening for the rack to penetrate is formed in the base, a transmission gear is arranged between the driving gear and the rack and is rotatably connected into the cavity, and the gear ratio of the transmission gear to the driving gear is 4: 1. The purpose is that the requirement for the rotating strength of the motor during punching can be reduced through the arrangement.

Further, the motor is a servo motor. The motor can be immediately stopped to rotate when the motor is stopped through the arrangement, and the purpose of emergency danger avoidance can be achieved.
