Description

Technical Field

[0001] This utility model relates to the field of bolt stamping technology, specifically a bolt stamping device. Background Technology

[0002] A bolt stamping device is the core equipment for bolt production. Supported by a robust metal frame, it boasts excellent stability. A precise feeding mechanism at the top delivers bolt blanks to the stamping area at a fixed rhythm and accurate position. The stamping die in the middle, meticulously crafted according to bolt specifications, features a punch and die working in perfect harmony. Driven by powerful motors, it instantly applies immense pressure to the blank, rapidly shaping it. The bottom is equipped with a high-efficiency discharge device, ensuring the stamped bolts are promptly discharged and collected. The entire device features a compact design and coordinated operation of all parts, achieving high efficiency and precision in bolt production, significantly improving both production efficiency and bolt quality.

[0003] A search revealed that Chinese patent CN219561199U discloses a high-efficiency stamping device for bolt production. This patent describes an automatic clamping structure with adjustable clamping dimensions, comprising a workpiece groove, a limiting block, a first electric telescopic rod, a first connecting block, a second connecting block, clamping plates, and a second electric telescopic rod. The bolt workpiece is placed in the middle of the workpiece groove. Activating the first electric telescopic rod on one side of the limiting block causes the first connecting block to push the second connecting block to move. Simultaneously, activating the second electric telescopic rod adjusts the height distance between the two clamping plates, facilitating the clamping of bolt workpieces of different sizes until the bolt workpiece is clamped. This eliminates the need for manual adjustment of the clamping dimensions and allows for free adjustment, thus improving the device's practicality.

[0004] In this solution, although automatic clamping is achieved to prevent bolt wobbling, after the device is pressurized, when it is necessary to remove the material, the staff needs to manually remove it. Since the bolt is at a high temperature immediately after stamping, it is time-consuming and laborious to remove the material, which greatly reduces the work efficiency. In order to solve this technical problem, this utility model proposes a bolt stamping device. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides a bolt stamping device. It has the following beneficial effects:

[0016] (1) Start the electric push rod one, push mold one and mold two to move towards each other, insert the plate into the slot to make the two become one, forming an inner cavity for placing the workpiece to be processed. Mold one moves and drives the inclined block two to squeeze the inclined block one, compressing the spring two. After processing, the electric push rod one moves in the opposite direction to separate mold one and two. The inclined block two pushes the inclined block one, drives the baffle to move in the slide, compresses the telescopic rod and spring one, exposes the discharge hole to discharge the bolt. After discharge, the spring one resets the baffle. This device solves the problem of inconvenient discharge of existing bolt processing devices. Through the cooperation of various components, it realizes the rapid discharge of bolts after processing and improves work efficiency.

[0017] (2) Start the electric push rod two, which pushes the connecting plate down and drives the upper pressure plate connected to the connecting plate to move synchronously to press the bolt below. The slide rod ensures that the upper pressure plate moves smoothly and prevents deviation. During pressing, the upper pressure plate squeezes the spring three and the damping rod. The elasticity of the spring three and the damping force of the damping rod work together to buffer the downward pressure of the upper pressure plate. This device solves the problems of unstable stamping, easy damage to mold and impact on forming quality of existing bolt pressing equipment. Through the cooperation of these components, the pressing process is made more stable, the impact is reduced, the stability of the equipment and the bolt forming quality are improved, and the service life of the mold is extended.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] Example 1: A bolt stamping device includes a workbench 1. Mounting plates 2 are fixedly connected to both sides of the top of the workbench 1. An electric push rod 3 is fixedly connected to the outer wall of each mounting plate 2. A mold 4 is fixedly connected to the output end of the left electric push rod 3, and a mold 7 is fixedly connected to the output end of the right electric push rod 3. A sliding groove 10 is provided inside the workbench 1, and a baffle 9 is slidably connected inside the sliding groove 10. A spring 14 is fixedly connected inside the baffle 9. A wedge 15 is fixedly connected to the other end of the mold 4, and a wedge 16 is fixedly connected to the bottom of the mold 4, with the wedge 16 corresponding to the wedge 15. The mold has an internal discharge hole 11, and an internal cavity 5 is formed between mold 1 4 and mold 2 7. Mold 1 4 has a slot 6 inside. Mold 2 7 has an insert plate 8 fixedly connected to its outer wall and inserted into the slot 6. A pair of telescopic rods 12 are fixedly connected to the left side of the workbench 1. Spring 13 is sleeved on the outer wall of the telescopic rod 12. The other end of the telescopic rod 12 and spring 13 are fixedly connected to the left side wall of the baffle 9. A pair of positioning rods 17 are fixedly connected to the outer walls of both mold 1 4 and mold 2 7 and are slidably connected to the mounting plate 2. Mold 1 4 and mold 2 7 are slidably connected above the workbench 1.

[0027] Activate the electric push rod 3 on both mounting plates 2. The push rod exerts force to move mold 4 and mold 7 towards each other. During this process, the insert plate 8 precisely inserts into the slot 6, making mold 4 and mold 7 fit together tightly. As mold 4 moves, it drives the inclined block 16 to move synchronously. When inclined block 16 contacts inclined block 15, it will squeeze inclined block 15 downward, thereby compressing spring 14 inside the baffle 9. After inclined block 16 moves to the other side, spring 14 uses its elasticity to pop out inclined block 15, making it block on the other side of inclined block 16, placing the workpiece in the inner cavity 5 between mold 4 and mold 7. After processing and shaping, activate the electric push rod 3 in reverse to separate mold 4 and mold 7. When mold 14 moves, inclined block 2 16 pushes inclined block 15 outward. Inclined block 15 drives baffle 9 to slide outward within slide groove 10, compressing telescopic rod 12 and spring 13. The discharge hole 11 is then exposed, and the machined bolt falls out. After discharge, spring 13 uses its elasticity to reset baffle 9, preparing it for the next processing. The close cooperation of all components enables rapid bolt discharge after processing, greatly improving work efficiency.

[0028] Example 2: The difference between this example and Example 1 is that, in this example, a bracket 18 is fixedly connected to the outer wall of the workbench 1, an electric push rod 19 is fixedly connected to the top of the bracket 18, a connecting plate 20 is fixedly connected to the output end of the electric push rod 19, springs 22 are fixedly connected to the bottom of each of the four corners of the connecting plate 20, an upper pressure plate 23 is fixedly connected to the other end of the springs 22, a pair of damping rods 24 are fixedly connected to the top of the upper pressure plate 23, the other end of the damping rods 24 is fixedly connected to the bottom of the connecting plate 20, and slide rods 21 are fixedly connected to the top of each of the four corners of the upper pressure plate 23, and the slide rods 21 are slidably connected inside the connecting plate 20, while the springs 22 are sleeved on the outer wall of the slide rods 21.

[0029] During the bolt pressing stage, the electric push rod 19 at the top of the support 18 is activated. After activation, the electric push rod 19 moves the upper pressure plate 23 on the connecting plate 20 downwards. As the upper pressure plate 23 gradually moves downwards, it presses the bolt until it is formed. During the pressing process, the upper pressure plate 23 simultaneously compresses the spring 22 and the damping rod 24. The damping rod 24, with its unique damping force, and the spring 22's own resilience, effectively buffer the downward pressure of the upper pressure plate 23. This buffering effect smoothly reduces the impact energy generated during the pressing process, making the pressing action more stable. In this way, the stability of the equipment is further improved, while also ensuring the bolt forming quality.

[0030] Working principle: When the operator needs to press the bolt into shape, the electric push rod 3 on both mounting plates 2 is activated. Under the action of the electric push rod 3, the mold 1 4 and mold 2 7 are moved towards the center, and the insert plate 8 is directly inserted into the slot 6, thus forming mold 1 4 and mold 2 7 as one unit. During the movement of mold 1 4, the inclined block 2 16 will move together. When the inclined block 2 16 contacts the inclined block 1 15, it will squeeze the inclined block 1 15 downward, thereby compressing the spring 2 14 in the baffle 9. When the inclined block 2 16 moves to the other side, the spring 2 14 will pop out the inclined block 1 15 through elasticity and block the inclined block 1 15 on the other side. The workpiece to be processed is placed in the inner cavity 5 between mold 1 4 and mold 2 7. After processing and shaping, the electric push rod 3 is activated in reverse to separate mold 1 4 and mold 2 7. When mold 1 4 moves, it pushes the inclined block 1 15 outward through the inclined block 2 16. At this time, the inclined block 1 15 will drive the baffle 9 to slide. The bolt moves outward from the groove 10, compressing the telescopic rod 12 and spring 13, thus exposing the discharge hole 11. The bolt then falls out through the discharge hole 11. During the downward processing, the elasticity of spring 13 resets the baffle 9, allowing for the next processing. Through their cooperation, the bolt is quickly discharged after processing, improving work efficiency. During the pressing process, the electric push rod 29 at the top of the bracket 18 is activated, causing the upper pressure plate 23 on the connecting plate 20 to move downward. The upper pressure plate 23 presses the bolt into shape. During the pressing process, the upper pressure plate 23 squeezes the spring 32 and damping rod 24. The damping force of the damping rod 24 and the elasticity of the spring 32 buffer the downward pressure of the upper pressure plate 23, smoothly reducing the impact energy during the pressing process, making the pressing action smoother, and further improving the stability of the equipment and the forming quality of the bolt.
