Stamping servo compensation system and working process thereof

Abstract

The invention relates to a stamping servo compensation system and a working process thereof. The stamping servo compensation system is composed of a human-computer interaction interface, a PLC motion controller, a hydraulic servo pump system, a servo proportional valve, a position sensor, pressure sensors, an electric control element, a hydraulic cylinder body and a stamping fixing template. One way of the PLC motion controller is connected with a servo pump drive which is connected with the servo pump. The servo pump is connected with the first pressure sensor. The other way of the PLC motion controller is connected to the servo proportional valve controlled by the PLC motion controller. The other way of the PLC motion controller is connected with the second pressure sensor and a displacement sensor. The displacement sensor is used for detecting the position of the stamping fixing mould plate. The stamping servo compensation system has the beneficial effects that by the utilization of the servo hydraulic drive and a position sensor feedback position closed-loop control system, high-precision pressure, position and synchronous control can be achieved; the servo pump driven by a servo motor is utilized, during standby, the motor does not rotate, and the energy-saving effect is remarkable; and torque and rotating speed of the servo motor are controlled precisely, and high-precision pressure and flow control is achieved.

Description

technical field [0001] The invention relates to a punching servo compensation system and its working process, which are applied in the technical field of powder metallurgy. Background technique [0002] In the molding process of powder metallurgy products, when using multi-layer die punching, the length of the die punches is different, but the pressure on the forming direction of the die punch forming section is the same. According to the elastic deformation relationship, the elastic deformation of the die punches is different. When the pressure is withdrawn on the return stroke of the upper punch, the lower die punch with large elastic deformation pushes the product away from the die punch with small elastic deformation, resulting in cracks due to the lack of effective support in some areas of the product during demoulding. In order to eliminate the impact of elastic deformation on the product during this process, it is necessary to set up an independent deformation compe...

Problems solved by technology

When the pressure is withdrawn on the return stroke of the upper punch, the lower die punch with large elastic deformation pushes the product away from the die punch with small elastic deformation, resulting in cracks when the product is demolded due to no effective support in some areas

In order to eliminate the impact of elastic deformation on the product during this process, it is necessary to set up an independent deformation compensation system on the fixed die plate with small deformation to improve this situation.
