Embodiment Construction

[0018] An automatic compensation method for the bottom dead point of a turret punch press, comprising the following steps:

[0019] C. When the turret punch program starts, the CMA program of the NC controller enters the information of different plates, and defines the wear amount Ⅰ of the mold core corresponding to the different plates, and transmits the wear amount Ⅰ as a variable Ⅰ to the PLC controller;

[0020] D. The PLC controller receives the variable Ⅰ, and the PLC controller judges the number of times the mold core is used, selects the wear amount II of the corresponding mold core, and judges whether automatic compensation of the bottom dead center position is required according to the wear amount II, and if compensation is not required When no variable is fed back to the NC controller, the bottom dead center is the original normal value; when compensation is required, the wear amount II is fed back to the NC controller as variable II, and the NC controller accepts th...

Abstract

The invention relates to an automatic compensation method of a bottom dead center of a turret punch press. The automatic compensation method comprises the following steps that different plate information is inputted by a CMA program, a variable I is transmitted to a PLC, the PLC selects corresponding abrasion loss II according to the variable I, and judges whether the position of the bottom dead center needs to be automatically compensated or not, and when compensation is needed, the abrasion loss II is used as a variable II to be fed back to an NC controller, and a new angle position of the bottom dead center is calculated by the CMA program. The using times of a die core is judged by the PLC to obtain corresponding abrasion loss of the die core, the new angle position of the bottom dead center is calculated by the CMA program for feeding the variable back to the NC controller, the problem that the in-die depth of the die core is not enough since the die core is worn is solved, the abrasion loss can be automatically compensated, and the enough in-die depth of the die core is ensured.

Description

technical field [0001] The invention relates to an automatic compensation method for the bottom dead point of a brick tower punching machine, which belongs to the technical field of brick tower punching machines. Background technique [0002] As we all know, the turret punch press belongs to the punching machine in the field of sheet metal processing. It is a special sheet metal forming processing machine. Its function is to use the mold to perform special functions such as stamping, forming, and rolling of the sheet metal. The realization of these functions is inseparable from the mold. The turret punching machine uses the mold to realize the processing of the plate. Since the processing of the plate by the mold is an extrusion process, what is indispensable is the wear of the mold core. The material of different plates, the length of service life of the mold, and the amount of wear on the core are also very different; the core is damaged, and the depth of the core into th...
