Description

Technical Field

[0001] This utility model relates to the field of belt pulley forging technology, specifically a precision edge punching die for belt pulley forging. Background Technology

[0002] Precision punching dies for pulley forging are used to remove excess burrs after forging, ensuring the pulley's dimensional accuracy, and punching mounting holes in the center or other locations of the pulley. The removed burrs protrude from under the die and fall into the receiving box below.

[0003] The burrs cut off fall into the receiving box. During production, the receiving box needs to be cleaned regularly to prevent burr accumulation. However, regular cleaning of the receiving box is time-consuming and can delay production. Therefore, a precision-fitting punching die for belt pulley forging is needed to solve the above problems.

The support platform is fixed to the upper end of the base, the opening is made at the lower end of the support platform, the receiving box is inserted into the opening, and part of the stamping part is fixed to the support platform and part is movably connected to the upper part of the support platform.

[0007] A movable component, comprising a hydraulic push rod, a baffle, a rubber ring, and a push plate, wherein the hydraulic push rod is fixed to one end of the opening, the baffle is fixed to the fixed end of the hydraulic push rod, the rubber ring is fixed to the outer ring of the baffle, and the push plate is fixed to the movable end of the hydraulic push rod.

[0008] Furthermore, the movable component also includes a fixing plate, which is fixed to the side of the support platform and located at one end of one of the openings, and the fixed end of the hydraulic push rod is fixed to the fixing plate.

[0009] Furthermore, the moving component also includes a connecting ring and a locking rod. One end of the connecting ring is fixed to the side of the baffle and sleeved on the hydraulic push rod. The locking rod is screwed to the side of the connecting ring and fits against the hydraulic push rod.

[0010] Furthermore, the movable component also includes a through hole, a fixing block, a telescopic locking block, and a pull plate. The through hole is opened in the middle of one end of the receiving box, the fixing block is fixed to the side of the base, the telescopic locking block is movably connected to the upper end of the fixing block and the upper end is inserted into the through hole, and the pull plate is fixed to the side of the telescopic locking block.

[0011] Furthermore, the end of the receiving box away from the through hole is attached to the baffle, and the push plate is movably connected inside the receiving box.

[0012] Furthermore, the stamping part includes a lower die and an upper die, the lower die being fixed to the middle of the upper end of the support platform, and the upper die being movably connected above the lower die via a hydraulic lifting system.

A rubber ring is attached to the inner wall of the opening. One hand presses down on the pull plate while the other pushes the receiving box into the opening, ensuring it fits against the baffle. Releasing the pull plate causes the telescopic locking block on the fixed block to move upward and engage in the through hole. The working frequency of the hydraulic push rod is set. After a period of production, the hydraulic push rod on the fixed plate activates, driving the push plate to move and pushing the accumulated burrs outward along the receiving box. This design allows for the periodic removal of accumulated burrs, saving labor and preventing disruption to production continuity due to missed cleaning. Attached Figure Description

The locking rod 23 is screwed to the side of the connecting ring 22 and fits against the hydraulic push rod 21.

[0034] The movable component also includes a through hole 27, a fixing block 28, a telescopic latch 29, and a pull plate 290. The through hole 27 is opened in the middle of one end of the receiving box 13. The fixing block 28 is fixed to the side of the base 10. The telescopic latch 29 is movably connected to the upper end of the fixing block 28, and the upper end is inserted into the through hole 27. The pull plate 290 is fixed to the side of the telescopic latch 29.

[0035] The end of the receiving box 13 away from the through hole 27 is attached to the baffle 24, and the push plate 26 is movably connected inside the receiving box 13;

[0036] The fixing plate 20 serves a fixing function, the hydraulic push rod 21 (model HSG-08-100) allows for position changes and is connected to an external hydraulic system via a hydraulic oil pipe, the connecting ring 22 serves a connecting function, the locking rod 23 serves a fixing function, the baffle 24 serves a blocking function to prevent burrs from falling to the other end of the opening 12, the rubber ring 25 serves a sealing function, the push plate 26 is used to push the burrs inside the receiving box 13, the through hole 27 serves a connecting function, the fixing block 28 serves a supporting function and has a spring installed inside, the connecting telescopic block 29 serves a limiting function, and the pull plate 290 facilitates hand movement of the telescopic block 29.

[0037] Working principle:

[0038] Tighten the locking rod 23 by putting the connecting ring 22 on the hydraulic push rod 21, and then insert the hydraulic push rod 21 into the opening 12 and fix it on the fixing plate 20. The rubber ring 25 is attached to the inner wall of the opening 12. Press down the pull plate 290 with one hand and push the receiving box 13 into the opening 12 with the other hand so that it fits against the baffle 24. Release the pull plate 290, and the telescopic block 29 on the fixing block 28 moves upward and gets into the through hole 27. Set the working frequency of the hydraulic push rod 21. After a period of production, the hydraulic push rod 21 on the fixing plate 20 starts, driving the push plate 26 to move and push the accumulated burrs out of the opening 12 along the receiving box 13.

[0039] This step allows for the periodic removal of accumulated burrs, saving labor and preventing disruptions to production due to missed cleaning.

[0040] Please see Figure 6 As shown, this embodiment, based on the above embodiment, further includes:

[0042] The connecting plate 30 is used to connect the push plate 26 and the inclined plate 31. The inclined plate 31 serves as a guide, and the rubber strip 32 serves as a blocking function.

[0043] Working principle:

[0044] The movable end of the hydraulic push rod 21 extends, driving the push plate 26 to move. As the push plate 26 moves, it also drives the inclined plate 31 and rubber strip 32 on the connecting plate 30 to move. The push plate 26 pushes the accumulated burrs, and the burrs that are being pressed down fall onto the inclined plate 31 and slide into the receiving box 13.

[0045] This step prevents the burrs falling from above from landing on the other side of the push plate 26 when it pushes the accumulated burrs, thus preventing the push plate 26 from returning to its original position.
