Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of blanking tool design, and particularly relates to a blanking tool for epoxy resin hard laminate insulating pad products. Background Art
[0002] Epoxy resin hard laminate insulating products (epoxy resin hard laminate insulating pad products) are as Figure 1 shown (where A and B are variable dimensions). The machining part of this product has two processes, including: Process 1, cutting blanks; Process 2, turning the outer shape. Currently, when cutting blanks in the first process, large sheets of raw materials need to be cut into square small blanks and holes are punched at the center position. During this process, operators use a manual shearing machine to cut the large sheets of raw materials multiple times to finally cut them into the required square blanks. This operation method not only has low efficiency, but also it is not easy to control the size of the square blanks in batch production manually. It is very easy to have inconsistent sizes on the four sides, and equal-distance cutting cannot be achieved. It is easy to have a poor consistency in the outer shape size of the blanks, which affects the processing efficiency of the outer shape turning process and wastes materials at the same time.

[0022] To make the purpose, content and advantages of the utility model clearer, the following further describes in detail the specific implementation manners of the utility model with reference to the drawings and embodiments.
[0023] The utility model provides a special tooling that can achieve rapid blanking, changes the original cutting method to a stamping method, and solves problems such as low processing efficiency, low material utilization rate, and poor quality consistency of insulating pad products. A special blanking tool for epoxy resin hard laminate insulating pad products is shown in Figure 2 、 Figure 3 , and mainly includes a fixing screw 1, a lower base 2, a positioning pin 3, a material supporting core 4, a punch 5, a connecting rod 6, a blanking retaining ring 7, a die 8, a replacement core 9, a spring 10, a setscrew 11, and a limit screw 12.
[0024] Among them, the blank holder core 4 is connected to the lower base 2 through two positioning pins 3 and two springs 10; the punch 5 sequentially passes through the center holes of the blank holder core 4 and the lower base 2 and is fixed by a fixing screw 1; the replacement core 9 is fixed on the blank holder core 4 by screws; the die 8 is connected to the connecting rod 6 through a setscrew 11 and is sleeved on the positioning boss of the punch 5; the blanking retaining ring 7 is located on one side of the radial center hole of the connecting rod 6.
[0025] It can be replaced by making punches 5, dies 8, and replacement cores 9 with corresponding dimensions to realize the blanking processing of insulating pad products with different specifications and sizes, and can meet the processing requirements of the same product with different sizes.
[0026] The operation steps of the special blanking tool for epoxy resin laminate products of the present utility model are as follows: on the large-sized product blank raw material, drill the center holes of each product at a certain distance according to the order quantity, position the center holes in the positioning boss of the punch 5, the die 8 is connected to the connecting rod 6 through a setscrew 11, rotate the handwheel of the press to drive the connecting rod 6 and the die 8 to press down together, the die 8 compresses the product blank during the descent and drives the blank holder core 4 to move downward together, compressing the spring 10; when reaching the limit of the stroke of the blank holder core 4 downward, the product blank is blanked out by the punch 5. After lifting the handwheel of the press, the spring 10 extends to lift the blank holder core 4 and also lift the product blank away from the punch 5. Repeat this operation step, the small blanks blanked out move upward above the die 8, and when encountering the blanking retaining ring 7, they are forced to be discharged out of the tool in the direction of the blanking port, thus realizing the blanking function.
