[0025] like Figures 1-4 As shown, it illustrates a bolt processing punch press according to an embodiment of the present disclosure, which includes a punch press body 1, a worktable 2, a connecting frame 3, a fixing plate 4, a moving tube 5, a moving plate 6, a blocking plate 7, a first buffer spring 8, a moving rod 9, a connecting pin 10, an adjusting plate 11, and an adjusting tube 12. like Figure 3As shown, the worktable 2 is installed inside the punch press body 1, which is a common punch press machine tool on the market. The punch press body 1 includes a punching mechanism, a housing, a drive mechanism, and a control mechanism. The connecting frame 3 is set on the upper surface of the worktable 2, and an auxiliary groove is opened on the outer side of the connecting frame 3. The fixed plate 4 is installed inside the connecting frame 3, and a moving tube 5 passes through the fixed plate 4. A moving plate 6 is installed on the top of the moving tube 5. During the downward movement, the moving plate 6 can slide into the fixed plate 4 through the splicing groove. Both the fixed plate 4 and the moving plate 6 have placement grooves inside. When the moving plate 6 and the fixed plate 4 are connected, they form a complete punching groove to shape the top of the blank. The blocking plate 7... A first buffer spring 8 is installed on the upper surface of the blocking plate 7 on the outer surface of the moving tube 5. The top of the first buffer spring 8 is installed on the lower surface of the fixed plate 4. The moving rod 9 passes through the moving tube 5. A connecting pin 10 is threaded through the outer surface of the moving tube 5. One end of the connecting pin 10, which is threaded into the moving tube 5, abuts against the moving rod 9. The moving rod 9 needs to be adjusted in advance according to the length of the bolt blank. After adjustment, the connecting frame 3 is placed on the worktable 2. An adjusting plate 11 is installed on the outer surface of the moving rod 9. An adjusting tube 12 is installed on the upper surface of the adjusting plate 11. When the blank to be processed by the punch press body 1 is long, the position of the moving rod 9 needs to be adjusted. Under normal circumstances, the moving rod 9 does not need to be adjusted.

[0026] like Figure 4 As shown, a connecting strip 13 is installed on the outer side of the movable plate 6. The connecting strip 13 is slidably connected to the connecting frame 3 through the connecting groove. The function of the connecting strip 13 is to prevent the movable plate 6 from being stuck inside the fixed plate 4 and to assist the first buffer spring 8 in resetting. An auxiliary rod 14 is installed on the lower surface of the connecting strip 13. An auxiliary tube 15 is sleeved on the outer surface of the auxiliary rod 14. A second buffer spring 16 is installed inside the auxiliary tube 15. The top end of the second buffer spring 16 is installed at the bottom end of the auxiliary rod 14. When the movable plate 6 moves downward, it can drive the connecting strip 13 to move downward, so that the first buffer spring 8 is stretched and the second buffer spring 16 is compressed.

[0027] like Figure 2 As shown, a fixing block 17 is slidably connected to the inside of the workbench 2 via an auxiliary groove. The auxiliary groove is an inverted T-shaped groove, and the fixing block 17 is an inverted T-shaped block. A contact plate 18 is installed on the upper surface of the fixing block 17, and a fixing rod 19 passes through the upper surface of the contact plate 18. A fixing hole 20 is opened on the upper surface of the workbench 2. One end of the fixing rod 19 passes through the contact plate 18 and is inserted into the fixing hole 20 located on the inner side. A contact block 21 is slidably connected to the inside of the contact plate 18 via a contact groove. A contact piece 22 is installed on the inner side of the contact block 21. After the contact piece 22 contacts the connecting frame 3, it can block the connecting frame 3. A fixing pin 23 is threaded through the inside of the contact block 21. The fixing pin 23 is slidably connected to the contact plate 18 via the fixing groove. It should be noted that the bolt blanks and blanks mentioned in this article are in a state that has just been cut by an external cutting machine, and there are no other processing steps before stamping.

[0028] In this embodiment, the connecting pin 10 is loosened counterclockwise according to the length of the bolt blank, and the moving rod 9 is moved upward along the moving tube 5. The upward movement of the moving rod 9 drives the adjusting plate 11 to move upward, and the upward movement of the adjusting plate 11 drives the adjusting tube 12 to move upward. After adjustment, the connecting pin 10 is tightened clockwise so that when the moving plate 6 enters the interior of the fixed plate 4, the length of the blank left in the stamping groove matches the length of the bolt head after stamping. Place the connecting frame 3 on the upper surface of the workbench 2. Move the operating contact plate 18 inward along the workbench 2 via the fixing block 17. The inward movement of the contact plate 18 causes the contact block 21 to move inward. The inward movement of the contact block 21 causes the contact piece 22 to move inward. The contact plate 18 moves inward and contacts the connecting frame 3. The operating fixing rod 19 passes through the contact plate 18 and is inserted into the fixing hole 20 located on the inner side. Loosen the fixing pin 23 counterclockwise. Move the operating contact piece 22 inward and cause the contact block 21 to move inward. The contact piece 22 moves inward and contacts the connecting frame 3. Then tighten the fixing pin 23 clockwise. The billet is inserted into the adjusting tube 12 through the moving plate 6 and the fixed plate 4 so that the billet can move with the moving plate 6. The punching mechanism inside the punch press body 1 moves downward, pushing the moving plate 6 downward. The moving plate 6 moves downward, causing the moving tube 5 to move downward. The moving tube 5 moves downward along the fixed plate 4. The moving tube 5 moves downward, causing the blocking plate 7 to move downward. The blocking plate 7 moves downward, stretching the first buffer spring 8. The moving tube 5 moves downward, causing the moving rod 9 to move downward. The moving rod 9 moves downward, causing the adjusting plate 11 to move downward. The adjusting plate 11 moves downward, causing the adjusting tube 12 to move downward. The adjusting tube 12 moves downward, causing the billet to move downward. When the moving plate 6 moves downward into the fixed plate 4, the length of the blank left in the stamping groove is the same as the length of the bolt head after stamping. At the same time, the moving plate 6 moves downward, causing the connecting bar 13 to move downward. The connecting bar 13 moves downward along the inside of the connecting frame 3. The downward movement of the connecting bar 13 causes the auxiliary rod 14 to move downward. The auxiliary rod 14 moves downward along the inside of the auxiliary tube 15. The downward movement of the auxiliary rod 14 compresses the second buffer spring 16. The stamping mechanism stamps the top position of the blank, so that the round head of the blank is stamped into a hexagon. After the stamping is completed, the stamping mechanism moves away from the moving plate 6. The first buffer spring 8 rebounds and drives the blocking plate 7 to move upward. The upward movement of the blocking plate 7 drives the moving tube 5 to move upward. The upward movement of the moving tube 5 drives the moving rod 9 to move upward. The upward movement of the moving rod 9 drives the adjusting plate 11 to move upward. The upward movement of the adjusting plate 11 drives the adjusting tube 12 to move upward. The moving tube 5 moves upward along the inside of the fixed plate 4. At the same time, the second buffer spring 16 rebounds and drives the auxiliary rod 14 to move upward. The auxiliary rod 14 moves upward along the inside of the auxiliary tube 15. The upward movement of the auxiliary rod 14 drives the connecting strip 13 to move upward. The upward movement of the connecting strip 13, the moving tube 5, and the adjusting tube 12 lifts the moving plate 6 and the stamped blank upward. The operator removes the stamped blank, replaces it with a new blank, and repeats the above operation to continue the stamping process.
