Technical Field

[0001] The invention relates to the field of bakelite processing equipment, in particular to bakelite automatic feeding and stamping equipment. Background Art

[0002] Bakelite, also known as bakelite, is a board made of high-quality bleached wood paper and cotton linter paper as reinforcement, and phenolic resin made from high-purity, fully synthetic petrochemical raw materials as resin adhesive. Bakelite has the characteristics of insulation, no static electricity, wear resistance and high temperature resistance, and is used as insulating switches and variable resistors for electronic products, molds for machinery, jigs on production lines, and can be used in transformer oil and other products. It is often used in driving parts, electrical equipment and insulating structural parts with high mechanical performance requirements, such as jigs, switchboards, and electrical machinery parts.

[0003] Bakelite is the processing blank required for electrical parts. Usually, it needs to be punched into the target size and punched into the target hole position before it can be used as a finished product. However, the current method of punching is to manually feed the material into the punch press, which is very slow and has a low degree of automation. Bakelite is also inconvenient to take and cannot be punched continuously one by one. The qualified rate of finished products is not high, and waste sorting is very troublesome and time-consuming.

The empty material sensing photoelectric switch 23 is arranged at the roller feed group 22 to detect whether there is a bakelite board in the roller feed group 22. The empty material sensing photoelectric switch 23 is also electrically connected to the hooking mechanism 12. When the empty material sensing photoelectric switch 23 senses empty material, it sends a signal to control the hooking mechanism 12 to perform a hooking action; the punch press 3 is arranged in the discharging direction of the roller feed group 22 and performs a continuous punching action. The punch press 3 is also electrically connected to the empty material sensing photoelectric switch 23.

The stacked bakelite boards to be processed are placed on the pallet 11, and the bakelite boards are fed by the roller feeding group 22 to the punch press 3 for continuous punching of products. When the empty material sensing photoelectric switch 23 senses empty material, it sends a signal to the hooking mechanism 12 to hook the material to the roller feeding group 22 and the punch press 3 to stop punching. After the empty material sensing is eliminated, the punch press 3 resumes punching.

[0028] It also includes a joint waste hopper device 5, and the empty material sensing photoelectric switch 23 is electrically connected to a pulse generator. The detection accuracy of the pulse generator is 1 mm / pulse. The pulse generator is also electrically connected to the control system 4, the punch press 3, the roller feeding group 22, and the joint waste hopper device 5. The punch press 3 is also equipped with a counting photoelectric switch for counting the number of punching times. The specific installation position is next to the brake disc of the punch press. The control system 4 obtains the counting signal of the counting photoelectric switch. The control system 4 can set the modulus. After the pulse generator detects that the pulse amount of the feeding displacement of the roller feeding group 22 reaches the set modulus, it sends a signal to the control system 4 to stop the action of the punch press 3 and sends a signal for the joint waste hopper device 5 to run the material receiving action.
