Description

Technical Field

[0001] The utility model relates to the technical field of heat sink production equipment, in particular to a stamping device for heat sink production. Background Art

[0002] A heat sink is a heat dissipation device made of aluminum alloy or copper, in the shape of a plate or sheet. It is mostly used to dissipate heat from heat-prone components in electrical equipment. The heat of the heat-generating components themselves can be effectively transferred to the heat sink, and then dissipated into the surrounding air through the heat sink. Some larger heat sinks require the use of a stamping machine for stamping during production. Existing stamping machines all stamp the raw material sheet placed on a horizontal workbench by moving the stamping mechanism downward.

[0003] At present, the heat sinks in the existing technology need to be stamped in large quantities in order to mass-produce heat sinks with the required consistent shape. Now, the cut heat sink material is generally placed on a stamping device, and the desired shape is obtained by stamping between the upper and lower dies. However, the existing heat sink stamping process has a low degree of automation and requires a lot of manpower for cutting, which is not conducive to improving the processing efficiency of the heat sink. In addition, the usual motor stamping device simply adopts a direct pressing method, which makes the pressing effect mediocre. It is difficult to effectively stamp thicker materials. Therefore, there is a need for a stamping device for heat sink production to solve this problem. Utility Model Content

[0035] Embodiment 2:

[0036] See also Figure 5-6 , and combined with Example 1, it is further obtained that the stamping mechanism 4 includes a mounting plate 41, the mounting plate 41 is fixedly mounted on the top of the stamping table 1, and a third motor 42 is fixedly mounted on the inner side of the mounting plate 41, and a transmission disc 43 is rotatably mounted on one end of the mounting plate 41 away from the output shaft of the third motor 42, and a second belt 44 is rotatably mounted between the transmission disc 43 and the output shaft of the third motor 42, and the transmission disc 43 extends to another set of mounting plates 41.

The second large gear 49 extends to the inner end of the mounting plate 41 and is fixedly installed with a wedge shaft 410, and the wedge shaft 410 is rotatably connected to the mounting plate 41. A connecting rod 411 is fixedly installed on the outside of the wedge shaft 410, and a sliding plate 412 is fixedly installed on the bottom of the connecting rod 411, and the sliding plate 412 is slidably connected to the mounting plate 41, and a stamping plate 413 is fixedly installed on the bottom of the sliding plate 412. A model block 47 is fixedly installed on the side of the stamping table 1 near the stamping plate 413 to increase the downward pressure and make the downward pressure effect better.

[0037] Furthermore, there are two groups of mounting plates 41 symmetrically distributed on both sides of the stamping table 1 to facilitate supporting the stamping device.

[0038] In actual operation, when this device is used, first, the heat sink to be stamped is placed between the limit frames 3213, supported by the upper baffle 3212, and the second motor 322 is started, so that the second motor 322 drives the transmission rod 323 to rotate on the first fixed block 325 and the second fixed block 326 through the first belt 324. When the transmission rod 323 rotates, the turntable 327 is driven to rotate, and the sliding groove 328 on the turntable 327 is used to squeeze and pull back the push rod 3210, so that the push rod 3210 drives the lower baffle 3211 to rotate on the third When the fixed block 329 moves back and forth, and the two groups of push rods 3210 move alternately, the upper baffle 3212 connected to the push rod 3210 of the higher group moves backward, and the heat sink will fall onto the lower baffle 3211. At the same time, when the lower baffle 3211 moves backward, the first heat sink will fall onto the roller 314 through the drop plate opening 3214. At the same time, the lower baffle 3211 moves backward, and the lower baffle 3211 will move forward to block the second heat sink from falling, forming an interval drop plate, which increases the safety time for stamping and workers to pick up, eliminates the safety hazards of manual delivery, and reduces labor costs. Then, the first motor 312 is turned on to drive the transmission shaft 313 to rotate, and the roller 314 is driven to rotate by the transmission belt 315 to facilitate the falling heat sink to move toward the stamping direction. When the heat sink moves to the model block 47, the third motor 42 is turned on at this time, so that the third motor 42 drives the transmission disk 43 to rotate through the second belt 44. When the transmission disk 43 rotates, it drives the first small gear 45 on the other side to rotate, so that the first small gear 45 and the first large gear 46 engage with each other and rotate. When the first large gear 46 rotates, it drives the second small gear on the other side. The gear 48 rotates, causing the second small gear 48 to mesh and rotate with the second large gear 49. When the second large gear 49 rotates, it drives the wedge-shaped shaft 410 on the inner side of the mounting plate 41 to rotate and squeeze the connecting rod 411, so that the sliding plate 412 at the lower end of the connecting rod 411 is forced to slide downward on the inner side of the mounting plate 41, so that the stamping plate 413 under the sliding plate 412 is stamped toward the model block 47. The flywheel energy storage and the pedal clutch are utilized to instantly release the energy of the rapidly rotating large wheel to the punch, generating a huge impulse to stamp the workpiece, thereby increasing the stamping effect.
