The punching and forming device includes an upper mold, a hydraulic cylinder, a lower mold and a bracket fixed on the frame, and the hydraulic cylinder is fixed on the bracket. , the upper mold is set above the lower mold and is fixedly connected with the piston rod of the hydraulic cylinder. The rack is located at the lower part of the lower mold and is provided with a blanking hole. There is also a photoelectric sensor used to detect whether there is a pole piece falling from the blanking hole. The pole piece conveyor belt includes shaft rollers arranged at both ends and a material belt sleeved outside the two shaft rollers. The two shafts At least one shaft roller among the rollers is connected to the stepping motor B, and the stepping motor A, the photoelectric sensor, the hydraulic cylinder, and the stepping motor B are all connected to the controller.

A plurality of elastic guide columns are arranged between the upper mold and the lower mold, and the elastic guide columns include a sleeve arranged on the upper mold and a guide rod arranged on the lower mold, and the upper end of the guide rod is inserted into the In the sleeve, a spring is also arranged in the sleeve. One end of the spring presses against the bottom of the sleeve, and the other end of the spring presses against the end of the guide rod.

The bracket is also provided with a rod sleeve for guiding the piston rod of the hydraulic cylinder.

When working, the discharge guide roller drives the material belt to step forward. After each step of the material belt by a set length, the controller controls the hydraulic cylinder to drive the upper die to punch down once, and the finished pole piece falls from the blanking hole to the Conveyor belt, and the drop of the pole piece is detected by the photoelectric sensor, the controller controls the stepper motor B to step forward for a set length, and then the discharge guide roller moves again to start the next workpiece processing. In this way, the automatic processing is completed, and the finished pole pieces are neatly arranged on the conveyor belt.

The utility model has the following advantages:

The utility model realizes automatic forming and sorting of pole pieces, has high degree of automation, saves manpower, high processing efficiency, stable processing quality, and reduces production cost.
