Technical Field
[0001] This invention relates to the field of shaft punching technology, specifically to an automated high-precision shaft punching production device. Background Technology
[0002] A shaft punching production device is a device used to process axial raised ribs on the surface of metal bars or shaft parts. It is a specialized automated equipment that uses plastic deformation to press out multiple axial raised ribs in one go. Its core purpose is to efficiently and precisely manufacture shafts with specific ribs, which play a key role in industry.
[0003] Currently available shaft punching production equipment requires a hopper or V-shaped roller conveyor to continuously feed metal rods into the punching die during shaft punching. Since the metal rods in the hopper or roller conveyor are cylindrical and arranged in the hopper, multiple metal rods are prone to stacking during feeding, causing blockage of the feeding port. Furthermore, due to the easy rolling characteristics of cylindrical metal rods, multiple rods can easily be ejected from the hopper at once during feeding. Summary of the Invention

Furthermore, during the unloading process, due to the easy rolling characteristics of the cylindrical metal rods, multiple materials can easily be ejected from the hopper at once. To achieve the above objectives, the present invention provides the following technical solution: an automated high-precision shaft punching production device, comprising a punching equipment body, a worktable, a hydraulic device body fixedly installed on the punching equipment body, and a material storage box fixedly connected to the worktable. A first fixing plate is fixedly connected to the outer wall of the material storage box, and a plurality of first return springs are fixedly connected to the outer wall of the first fixing plate. One end of each first return spring is fixedly connected to a feeding track. A plurality of shaft bodies are placed on the feeding track. One end of the feeding track is hinged to the inner wall of the material storage box. A first sliding groove is formed in the inner wall of the material storage box. A first guide rod is slidably connected to the inner wall of the first sliding groove. A third fixing plate is fixedly connected to one end of the first guide rod. A second guide rod and a third guide rod for clamping the feeding track are fixedly connected to the outer wall of the third fixing plate.

[0006] Preferably, a sliding block is fixedly connected to the outer wall of the second fixed plate, and a third electric slide rail is fixedly installed on the inner wall of the material storage box, with the sliding block fixedly connected to the moving end of the third electric slide rail.
[0007] Preferably, the inner wall of the first groove is fixedly connected with a plurality of evenly distributed first abutment blocks, the first abutment blocks are configured as hemispherical shapes, and a first ball is rotatably mounted on one end of the first guide rod, the first ball being slidably connected to the inner wall of the first groove.
[0008] Preferably, a first guide plate is fixedly connected to the inner wall of the material storage box, a fixed frame is fixedly connected to the outer wall of the first guide plate, a fourth guide rod is rotatably connected to the outer wall of the fixed frame, a torsion spring is sleeved on the fourth guide rod, one end of the torsion spring is fixedly connected to the outer wall of the fixed frame, the other end of the torsion spring is fixedly connected to a second guide plate, and the outer wall of the fourth guide rod is fixedly connected to the outer wall of the second guide plate.
[0009] Preferably, the outer wall of the second guide plate has an inclined surface, and a second abutting block is fixedly connected to the outer wall of the second guide plate. The outer wall of the second abutting block has a first inclined surface and a second inclined surface.
[0010] Preferably, a third guide plate is fixedly connected to the outer wall of the first guide plate, and the third guide plate is set at an inclined angle.
[0011] Preferably, a hydraulic rod is fixedly connected to the output end of the main body of the hydraulic device, a punching mold is fixedly connected to one end of the hydraulic rod, a storage box is fixedly connected to the outer wall of the worktable, and a control console is fixedly installed on the outer wall of the worktable.

[0013] Preferably, the moving ends of both the first and second electric slide rails are fixedly equipped with electric clamps for clamping the shaft body.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, the third electric slide rail is activated, causing the second guide plate to rotate with the fourth guide rod. The upward rotation of the second guide plate causes the surface angle of the inclined surface to gradually change from upward to downward. At this time, the shaft body on the inclined surface will slide along the downward inclined surface towards the first guide plate. During the rotation of the second guide plate, the remaining shaft bodies can be pushed to the upper left to prevent them from rolling down together.
[0015] 2. In this invention, in order to prevent multiple shaft bodies from stacking together, after the third electric slide rail is activated, the unloading track clamped in the second guide rod and the third guide rod will be intermittently pressed and shaken by the outer wall of the third fixed plate. The shaking will cause the shaft bodies stacked together on the unloading track to be shaken off and spread flat on the surface of the unloading track.
[0016] 3. In this invention, when the shaft body is unloaded, the third electric slide rail is activated. The clamping of the unloading track by the second and third guide rods makes the tilt angle of the unloading track gradually become steeper and steeper, making the gravity effect on multiple shaft bodies more significant. This can offset the frictional force between the shaft body and the inner wall of the material storage box, allowing the shaft body to slide smoothly along the tilt angle of the unloading track.

[0020] Example 1: This example addresses the problem that when cylindrical metal rods are arranged in a hopper or roller conveyor, multiple rods can easily stack during feeding, causing blockage at the feeding port. Furthermore, due to the inherent rolling properties of cylindrical metal rods, multiple rods can easily detach from the hopper at once during feeding. Please refer to [link to relevant documentation]. Figure 1 - Figure 8 An automated high-precision shaft punching production device includes a punching equipment body 1, a worktable 2, a hydraulic device body 4 fixedly installed on the punching equipment body 1, and a material storage box 10 fixedly connected to the worktable 2. A first fixing plate 11 is fixedly connected to the outer wall of the material storage box 10. A plurality of first return springs 12 are fixedly connected to the outer wall of the first fixing plate 11. One end of the first return spring 12 is fixedly connected to a feeding track 13. A plurality of shaft bodies 14 are placed on the feeding track 13. One end of the feeding track 13 is hinged to the inner wall of the material storage box 10. A first sliding groove 16 is opened on the inner wall of the material storage box 10. A first guide rod 20 is slidably connected to the inner wall of the first sliding groove 16. A third fixing plate 23 is fixedly connected to one end of the first guide rod 20. A second guide rod 24 and a third guide rod 25 for clamping the feeding track 13 are fixedly connected to the outer wall of the third fixing plate 23.
[0021] A second return spring 22 is sleeved on the first guide rod 20. One end of the second return spring 22 is fixedly connected to the second fixing plate 19, and the other end of the second return spring 22 is fixedly connected to the outer wall of the third fixing plate 23. The first guide rod 20 is slidably connected to the inner wall of the second fixing plate 19.
[0022] A sliding block 18 is fixedly connected to the outer wall of the second fixed plate 19, and a third electric slide rail 17 is fixedly installed on the inner wall of the material storage box 10. The sliding block 18 is fixedly connected to the moving end of the third electric slide rail 17.
[0023] A third guide plate 36 is fixedly connected to the outer wall of the first guide plate 27. The third guide plate 36 is set at an inclined angle.
[0024] A hydraulic rod 7 is fixedly connected to the output end of the main body 4 of the hydraulic device. A punching mold 8 is fixedly connected to one end of the hydraulic rod 7. A storage box 9 is fixedly connected to the outer wall of the worktable 2. A control console 3 is fixedly installed on the outer wall of the worktable 2.
[0025] The outer wall of the worktable 2 is fixedly installed with a first electric slide rail 5 and a second electric slide rail 6.
[0026] Both the moving ends of the first electric slide rail 5 and the second electric slide rail 6 are fixedly equipped with electric clamps 15 for clamping the shaft body 14.
[0027] In this embodiment: When using the shaft punching production device, the shaft body 14 to be processed is first placed on the feeding track 13 in the material storage box 10. At this time, the shaft body 14 will slide down along the inclined feeding track 13. However, since the inclined surface 32 on the surface of the second guide plate 31 is inclined, the shaft body 14 is stopped after sliding along the feeding track 13 and contacting the inclined surface 32. When the shaft body 14 needs to be unloaded, the third electric slide rail 17 is activated. The moving end of the third electric slide rail 17 moves synchronously with the sliding block 18. The sliding block 18 moves synchronously with the second fixed plate 19, the first guide rod 20, and the third fixed plate 23. When the third fixed plate 23 moves, it moves synchronously with the second guide rod 24 and the third guide rod 25. As the second guide rod 24 moves, its outer wall abuts against the second inclined surface 35. The abutting force causes the second inclined surface 35 to drive the second abutting block 33 and the second guide plate 31 to generate an upward force. This causes the second guide plate 31 to rotate around the fourth guide rod 29, and the torsion spring 30 is simultaneously twisted and stores force. The upward rotation of the second guide plate 31 causes the inclined surface 32, which is at an inclined angle, to gradually approach a horizontal angle. Subsequently, the surface angle of the inclined surface 32 gradually changes from upward to downward. At this time, the shaft body 14 on the inclined surface 32 will slide along the downward inclined surface 32 toward the first guide plate 27. During the rotation of the second guide plate 31, the remaining shaft bodies 14 can be pushed to the upper left to prevent them from rolling down together. A single shaft body 14 rolls down the first guide plate 27 onto the third guide plate 36, and then falls down the third guide plate 36 into the electric clamp 15. The electric clamp 15 is activated to clamp the shaft body 14. Then, the first electric slide rail 5 is activated to transport the electric clamp 15 and the shaft body 14 toward the punching die 8 until the shaft body 14 is inserted into the punching die 8. At this time, the electric clamp 15 is activated to release the clamp on the shaft body 14, allowing the shaft body 14 to fall into the die. It should be noted that the electric clamp adopts a left and right clamping method, with hollow channels reserved at the top and bottom to facilitate the falling of the shaft. When moving to the vicinity of the punching die 8, the electric clamp 15 extends 5-10mm beyond the outside of the first electric slide rail, and the extended end is aligned with the feed port of the punching die 8 to ensure that the shaft falls accurately into the die.
[0028] At this time, the hydraulic device body 4 is activated, moving the hydraulic rod 7 downwards. The downward movement of the hydraulic rod 7 causes the upper and lower parts of the punching mold 8 to quickly close, performing a punching operation on the shaft body 14 inside the punching mold 8. After punching, the hydraulic device body 4, along with the hydraulic rod 7 and the punching mold 8, moves upwards synchronously. The punched shaft body 14 can then be moved by activating the second electric slide rail 6. The second electric slide rail 6 moves the electric clamp 15 at its moving end until the electric clamp 15 protrudes beyond the second electric slide rail 6, with part of the electric clamp 15 positioned inside the punching mold 8. Subsequently... The electric clamp 15 is activated to clamp the shaft body 14 in the punching mold 8, and the second electric slide rail 6 is activated to move the electric clamp 15 and the shaft body 14 toward the first electric slide rail 5. Finally, the punched shaft body 14 is moved onto the electric clamp 15 corresponding to the first electric slide rail 5. Then, the first electric slide rail 5 is activated to move the finished shaft body 14 in the electric clamp 15 to the top of the storage box 9. The clamping of the shaft body 14 by the electric clamp 15 is released, so that the punched shaft body 14 falls into the storage box 9 for collection.
[0029] Example 2: This example addresses the problem that when cylindrical metal rods are arranged in a hopper or roller conveyor, multiple rods can easily stack during feeding, causing blockages at the feeding port. Furthermore, due to the inherent rolling properties of cylindrical metal rods, multiple rods can easily detach from the hopper at once during feeding. This example is an improvement upon Example 1. For details, please refer to [link to example]. Figure 1 - Figure 8 The inner wall of the first groove 16 is fixedly connected with a plurality of evenly distributed first abutment blocks 26. The first abutment blocks 26 are set in a hemispherical shape. One end of the first guide rod 20 is rotatably mounted with a first ball bearing 21. The first ball bearing 21 is slidably connected to the inner wall of the first groove 16.
[0030] The inner wall of the material storage box 10 is fixedly connected to a first guide plate 27, the outer wall of the first guide plate 27 is fixedly connected to a fixed frame 28, the outer wall of the fixed frame 28 is rotatably connected to a fourth guide rod 29, a torsion spring 30 is sleeved on the fourth guide rod 29, one end of the torsion spring 30 is fixedly connected to the outer wall of the fixed frame 28, the other end of the torsion spring 30 is fixedly connected to a second guide plate 31, and the outer wall of the fourth guide rod 29 is fixedly connected to the outer wall of the second guide plate 31.
[0031] The outer wall of the second guide plate 31 is provided with an inclined surface 32, and a second abutment block 33 is fixedly connected to the outer wall of the second guide plate 31. The outer wall of the second abutment block 33 is provided with a first inclined surface 34 and a second inclined surface 35.
[0032] In this embodiment: when a large number of shaft bodies 14 are added into the material storage box 10, in order to prevent the large friction between the shaft body 14 and the inner wall of the material storage box 10 from causing the shaft body 14 to be unable to slide down along the inclined angle of the feeding track 13, the third electric slide rail 17 is activated when feeding the shaft body 14. When the third electric slide rail 17 moves to the left with the sliding block 18, the second fixed plate 19, the third fixed plate 23, the second guide rod 24 and the third guide rod 25, the clamping of the feeding track 13 by the second guide rod 24 and the third guide rod 25 makes the inclined angle of the feeding track 13 gradually become steeper and steeper, so that the multiple shaft bodies 14 are more significantly subjected to the effect of gravity, which can offset the influence of the friction between the shaft body 14 and the inner wall of the material storage box 10, so that the shaft body 14 can slide down smoothly along the inclined angle of the feeding track 13.
[0033] To prevent multiple shaft bodies 14 from stacking together, after the third electric slide rail 17 is activated, when the third electric slide rail 17 moves synchronously with the sliding block 18, the second fixing plate 19, the third fixing plate 23, the second guide rod 24, and the third guide rod 25, the first guide rod 20 and the first ball 21, which are located in the first slide groove 16, move synchronously. The first ball 21 will abut against multiple evenly distributed first abutment blocks 26 on its moving trajectory. Since the first abutment block 26 is designed with a hemispherical shape, when the abutment occurs, the first ball 21 will slide along the surface of the first abutment block 26, causing the first ball 21 to move away from the first abutment block 26 along with the first guide rod 20. The first ball bearing 21 and the first guide rod 20 move a certain distance in the direction of the first ball bearing 21 and the first guide rod 20, and because there are multiple first contact blocks 26 evenly arranged, the first ball bearing 21 and the first guide rod 20 move a certain distance in the direction away from the first slide groove 16 during the movement. The movement of the first guide rod 20 will slide along the second fixed plate 19, and the movement of the first guide rod 20 will cause the third fixed plate 23 and the second guide rod 24 and the third guide rod 25 to move synchronously. The unloading track 13 clamped in the second guide rod 24 and the third guide rod 25 will be intermittently pressed and shaken by the outer wall of the third fixed plate 23. The shaking will cause the shaft body 14 stacked on the unloading track 13 to be shaken off and spread flat on the surface of the unloading track 13.
