Description

Technical Field

[0001] The utility model relates to the technical field of cold stamping dies, in particular to a cold stamping die for metal products. Background Art

[0002] Cold stamping is a processing method that uses a stamping die to apply pressure to the material on a press at room temperature to separate or deform the material, thereby obtaining a product with a certain shape, size and performance. It is often used in the processing of some metal products. With the improvement of processing requirements, the cold stamping dies used in production also need to be continuously optimized and improved. For example, the authorized patent with announcement number CN211191622U proposes "by setting a moving block, a slide groove and a screw, the screw drives the moving block to slide on the slide groove, and the lower die seat is staggered from the upper die seat when the staff loads and unloads, separating the working area from the dangerous area where accidents may occur, preventing the staff from reacting in time due to fatigue, and failing to pull their hands out in time when the upper die seat is pressed down, resulting in accidents."

[0003] Theoretically, the above-mentioned prior art is feasible. However, in actual processing, according to the applicant's many years of experience in cold stamping processing, the upper and lower molds of the stamping die need to be aligned within the tolerance during long-term processing. If the upper and lower molds of the stamping die are moved rashly, the processing accuracy will be affected, resulting in an increase in the number of defective workpieces.

[0036] Working principle:

[0037] Embodiment 1

[0038] For the bottom stamping die 3 and the top stamping die 4 in the unstamped state, the first electromagnetic suction cup 115 is opened and the second electromagnetic suction cup 116 is closed through the auxiliary controller 14, and the brake stepping motor 12 is started. The output end of the brake stepping motor 12 drives the first electromagnetic suction cup 115, the H-shaped sleeve 114, the transmission shaft 111 and the first gear 112 to rotate synchronously, and then the first gear 112 is engaged with the second gear 113, so that the second gear 113 drives the first hollow shaft 6 and the second hollow shaft 7 to flip, until the top of the synchronous pressure detection component 8 is in contact with the bottom surface of the auxiliary sleeve 10, and the brake stepping motor 12 is closed;

[0039] Subsequently, when the top punching die 4 moves uncontrollably, the auxiliary sleeve 10 moves downward synchronously to squeeze the cross rod 81, which then causes the cross rod 81 to press against the pressure sensor 9. When the pressure sensor 9 detects that the pressure value exceeds the preset value, the electronic emergency stop structure of the hydraulic mechanism 2 is linked to promptly suspend the entire equipment and reduce the probability of accidents.

[0040] Embodiment 2

[0041] For the bottom stamping die 3 and the top stamping die 4 at the end of a processing cycle, the first electromagnetic suction cup 115 is opened and the second electromagnetic suction cup 116 is closed through the auxiliary controller 14, and the brake stepping motor 12 is started. The output end of the brake stepping motor 12 drives the first electromagnetic suction cup 115, the H-shaped sleeve 114, the transmission shaft 111 and the first gear 112 to rotate synchronously, and then the first gear 112 is meshed with the second gear 113, so that the second gear 113 drives the first hollow shaft 6 and the second hollow shaft 7 to flip, until the top of the synchronous pressure detection component 8 fits and contacts the bottom surface of the auxiliary sleeve 10, and the brake stepping motor 12 is closed. When the top stamping die 4 moves uncontrolled later, the auxiliary sleeve 10 moves downward synchronously to squeeze the cross rod 81, and then the cross rod 81 presses the pressure sensor 9. When the pressure sensor 9 detects that the pressure value exceeds the preset value, the electronic emergency stop structure of the hydraulic mechanism 2 is linked to suspend the overall equipment in time;

[0042] After the synchronous pressure detection component 8 and the second hollow shaft 7 are rotated and adjusted, the first electromagnetic suction cup 115 is closed and the second electromagnetic suction cup 116 is opened through the auxiliary controller 14, and then the brake stepper motor 12 is restarted, so that the output end of the brake stepper motor 12 drives the multiple fan blades 132 to rotate synchronously in the yield sleeve 131, and then the airflow is forced to be generated and transported to the first hollow shaft 6 through the elastic hose 133, and then enters the guide inclined tube 15 through the second hollow shaft 7, and finally sprayed to the top surface of the bottom stamping die 3 through the guide inclined tube 15, and the bottom stamping die 3 after use is cleaned by air blowing.
