A semiconductor cooling plate is provided on the rear surface of the water tank.
[0004] The hexagonal head of the bolt can be stamped into shape using a stamping machine; however, after the hexagonal head is stamped, a burr edge will remain at the edge of the hexagonal head. At this time, the operator needs to perform turning to remove it, which makes the burr edge treatment of the hexagonal head time-consuming and laborious. Utility Model Content
[0005] The purpose of this invention is to provide a bolt burr pressure removal device, which can facilitate the convenient removal of burrs from the frame.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a bolt burr pressure removal device, comprising a press body, a punch head located on the press body and moving up and down with the transmission mechanism, and a punching table located on the press body and below the punch head. A base is provided on the punching table, and a seat hole is opened at the center of the base. A pressure seat is detachably connected to the seat hole. A hexagonal hole for embedding the hexagonal head of a bolt is opened in the pressure seat. A punching column is provided on the lower side of the punch head. A circular groove for embedding the screw end of a bolt is opened at the lower end of the punching column. An open slot for embedding the screw end in the circular groove is also opened at the lower end of the punching column.
[0007] A further feature of this invention is that a support ring for supporting the pressure seat is provided on the inner wall of the peripheral side of the seat hole, and a threaded hole is provided on the side of the base, and a locking bolt with its end abutting against the outer wall of the pressure seat is threaded into the threaded hole.
[0008] A further feature of this invention is that a temporary storage box for storing bolts to be stamped is provided on one side of the stamping table.
[0009] A further feature of this invention is that: a scrap box for collecting the removed burr edges is provided on the side of the stamping table; a first guide plate extending downward at an angle and allowing the burr edges to slide into the scrap box is provided on the upper side of the stamping table and on one side of the base; the cross-section of the first guide plate is U-shaped and an opening is provided on the side for the press seat to pass through; and a connecting arm connected to the stamping table is provided on the side of the first guide plate.
[0010] A further feature of this invention is that a dovetail slide bar is provided on the side of the waste box, and a dovetail groove for the dovetail slide bar to be inserted is provided on the side of the stamping table.
[0011] A further feature of this invention is that a storage box for storing stamped bolts is placed on the ground behind the stamping machine body, and a second guide plate extending toward the storage box is provided on the lower side of the stamping table.
[0012] A further feature of this invention is that a buffer plate is provided at the lower end of the second guide plate, a shaft hole is provided at one end of the buffer plate, a connection port is provided at the side of the lower end of the second guide plate, a rotating shaft is provided in the connection port and passes through the shaft hole, and a buffer torsion spring is sleeved on the rotating shaft, with one end connected to the buffer plate and the other end connected to the inner wall of the connection port.
[0013] In summary, this utility model has the following beneficial effects:
[0014] 1. When it is necessary to remove the burr edge of the bolt, the operator inserts the hexagonal head of the bolt into the hexagonal hole of the pressure seat, while the end of the bolt thread passes through the open slot and is inserted into the round slot. Then, the press machine is started, and the press head moves down to drive the press column to press down on the end face of the bolt thread. Then the entire bolt can pass through the hexagonal hole, while the burr edge around the hexagonal head remains on the upper side of the pressure seat. Finally, the burr edge can be removed relatively easily.
[0015] 2. When it is necessary to replace the pressure seat according to the bolt type, simply loosen the locking bolt to remove the pressure seat from the seat hole, and then the pressure seat on the base can be easily disassembled and assembled.
[0016] 3. A temporary storage box can be used to store bolts to be stamped, which makes it convenient for operators to access them.
[0017] 4. When the stamping is completed and the burr edge remains on the upper side of the pressure seat, the operator can move the burr edge to send it into the first guide plate. Then the burr edge can slide along the first guide plate into the scrap box, which can facilitate the quick collection of burr edge scrap.
[0018] 5. When there are many burrs on the edge of the scrap box and it needs to be cleaned, pull the dovetail slide bar of the scrap box out of the dovetail slide groove to complete the quick disassembly of the scrap box on the side of the stamping table, which will make it easier to retrieve the scrap box.
[0019] 6. When the bolt passes through the hexagonal hole and falls from the underside of the stamping table, the bolt can fall into the second guide plate. Then the bolt can slide down the second guide plate and fall into the storage box, which is convenient for storing the stamped bolt.
[0020] 7. When the bolt slips into the second guide plate, it will hit the buffer plate. As the buffer torsion spring deforms elastically, the buffer plate will open. The elastic force of the buffer torsion spring will buffer the slipping bolt, reducing the impact force of the bolt falling into the storage box. This will prevent the bolt surface from being damaged by excessive collisions between bolts. Attached Figure Description

Then, the press machine body 1 is started, and the press head 11 moves down, which drives the press column 111 to press down on the bolt shank end face. Then the entire bolt passes through the hexagonal hole 31 and falls into the second guide plate 8. After sliding down the second guide plate 8, the bolt falls into the storage box 7 after being buffered by the buffer plate 81. The burr edges around the hexagonal head remain on the upper side of the pressure seat 3. The operator can move the burr edges to send them into the first guide plate 6. Then the burr edges slide along the first guide plate 6 into the waste box 5, which facilitates the quick collection of burr edge waste.
