Description

Technical Field

[0001] The present application relates to the technical field of punching-tapping integrated processing, and in particular to a punching-tapping integrated processing equipment for automobile parts. Background Art

[0002] Punching is a process that uses a punching machine or a punching machine to place the workpiece in a die, and then use the punch to apply impact force to the plate, so that a hole is formed in the workpiece under the action of the punch and the die; tapping is the process of using a tapping tool (such as a tap) to process internal threads in the cavity of the workpiece based on the holes formed by punching or drilling.

[0003] In the case of Figure 5 When the support seat workpiece at the bottom of the car seat frame shown in the figure is punched and tapped, the workpiece is generally punched first by a punching device, and then the inner wall of the hole is threaded by a tapping device. Since the punching device and the tapping device are separated from each other and do not interfere with each other, the overall processing speed is relatively fast. Another method is to use integrated punching and tapping equipment for processing. The integrated equipment has a high degree of integration, requires fewer operators, and occupies less space. The specific operation process is as follows: the conveyor belt transports the workpiece to be processed to the punching die, and the loading structure such as an electric push rod or a mechanical gripper transfers the workpiece to the punching die for punching. After the punching is completed, the workpiece is moved to the tap for tapping. After the tapping operation is completed, the punching die is loaded for the next processing cycle.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: since the punching process is performed by rapid punching by the punch head, the punching process is relatively fast, while the tapping process requires the tap to be moved to the workpiece and then rotated for tapping. The tapping process is slower than the punching process. After each punching is completed, it is necessary to wait for the tapping to be completed before proceeding to the next step, which results in a slower overall processing speed of the punching-tapping integrated device. Summary of the invention

[0005] In order to improve the problem of having to wait for a long time after each cycle of the punching operation is completed, the present application provides an integrated punching and tapping processing equipment for automotive parts.

[0006] The present application provides an integrated punching and tapping processing equipment for automobile parts, which adopts the following technical solution: A punching-tapping integrated processing equipment for automobile parts, comprising a machine body, a conveyor belt, a punching arm and a tapping arm, the output end of the punching arm is fixedly connected to a punch, and the output end of the tapping arm is provided with a tap, characterized in that: a chassis ring connected to a power source is rotatably connected to the machine body, an inner material distribution plate is fixedly connected to the inner side of the chassis ring, and an outer material distribution plate is fixedly connected to the outer side of the chassis ring, two punching dies are fixedly connected to the chassis ring and are evenly distributed, and the top of the inner material distribution plate away from the punch and the top of the outer material distribution plate away from the punch are both fixedly connected to the tapping dies, there are two tapping arms, and they are respectively located above the two tapping dies, the punching dies and the tapping dies are both open at both ends along the radial direction of the chassis ring, and when the chassis ring is in a stationary state, the two tapping dies and the two punching dies are in a collinear line, and the chassis ring is provided with a waste opening below the punching dies; The machine body is provided with a transfer component for transferring the workpiece in the punching die between the two tapping dies to one of the tapping dies, and a loading component for transferring the workpiece on the conveyor belt to the punching die under the punch. The machine body is also provided with a driving component for driving the transfer component and the loading component.

[0007] By adopting the above technical solution, the transmission belt conveys the workpiece to the punching die, the driving component drives the loading component to make the workpiece enter the punching die, and then the punching arm presses down to make the punch punch a hole in the workpiece, and the waste falls from the waste outlet, and then the punching arm moves up to make the punch separate from the workpiece, and then the chassis ring rotates to the opposite position of the punching die and the tapping die, the driving component drives the transfer component to move the workpiece to the tapping die on the external material distribution plate, and then the tapping arm drives the tap to perform tapping operation. During the tapping operation, the chassis ring rotates to drive another punching die to move to the loading component for loading and punching operations. After the punching is completed, the chassis ring Rotate to move the punching die to the position opposite to the tapping die, and then the transfer component moves the workpiece to the tapping die on the inner dividing plate. At this time, the first punching die moves to the loading component for loading and punching, and then moves to the tapping die on the outer dividing plate. The transfer component moves the workpiece in the punching die toward the tapping die on the outer dividing plate, and the moved workpiece pushes out the workpiece in the tapping die, completing the unloading while also updating the workpiece to be processed in the tapping die. Since the punching operation is shared by two tapping stations, the whole process greatly shortens the waiting time required after each punching operation is completed.

[0008] Optionally, the driving assembly includes a driving gear ring fixedly connected to the peripheral wall of the bottom end of the chassis ring, an energy storage gear rotatably connected to the machine body and meshing with the driving gear ring, a clockwork spring arranged on the energy storage gear, a one-way gear rotatably connected to the machine body and a transmission shaft coaxially arranged at the end of the one-way gear, the one-way gear is meshingly connected with the energy storage gear, when the driving gear ring drives the energy storage gear to rotate, the energy storage gear drives the one-way gear to rotate idly, when the clockwork drives the energy storage gear to rotate, the one-way gear drives the transmission shaft to rotate synchronously, and the driving gear ring is also provided with a disengagement member for disengaging from its meshing with the energy storage gear; the disengagement member is a toothed portion opened on the driving gear ring, there are two toothed portions, and when the punching die moves to face the tapping die, the toothed portion on the driving gear ring faces the energy storage gear.

[0009] By adopting the above technical solution, when the chassis ring rotates, the active gear ring drives the energy storage gear to rotate, so that the spring on the energy storage gear is tightened. In this process, the energy storage gear drives the one-way gear to rotate, but the one-way gear idles and does not drive the transmission shaft to rotate. When the punching die on the chassis ring moves to the corresponding position, the chassis ring stops for a short time. At this time, the toothless part on the active gear ring is opposite to the energy storage gear, so that the active gear ring is disengaged from the energy storage gear and meshes with the energy storage gear. At this time, the energy storage gear is disengaged from the restraint of the active gear ring and is driven by the spring, thereby rotating the transmission shaft to drive the one-way gear to rotate. At this time, the one-way gear drives the transmission shaft to rotate. The rotating transmission shaft provides a power source with a stable rhythm for the transfer component and the drive component. This process does not require the addition of other hardware equipment such as electronic control and corresponding software algorithms, which greatly saves production costs. After the chassis ring continues to rotate, the toothless part is not opposite to the energy storage gear, and the active gear ring meshes with the energy storage gear again. The energy storage and release process of the energy storage gear has a simple structure and high stability.

[0010] Optionally, the end of the transmission shaft located in the one-way gear is elastically hinged with a one-way block, and the one-way gear includes an external tooth portion meshing with the energy storage gear and a ratchet portion meshing with the one-way block, and when the one-way block is in a free state, the one-way block and the ratchet portion are in a meshing state.

[0011] By adopting the above technical solution, when the one-way gear is indirectly driven by the active gear ring, the ratchet part squeezes the one-way block, and the one-way block vibrates back and forth due to the elastic effect. At this time, the ratchet part cannot push the one-way block. When the one-way gear is indirectly driven to rotate by the spring, due to the change in the rotation direction, the ratchet part pushes the one-way block to rotate, thereby causing the transmission shaft to rotate.

[0012] Optionally, the transfer assembly includes a driven plate connected to the transmission shaft, a first connecting rod eccentrically hinged on the end face of the driven plate, a screw rod slidably connected to the machine body, a threaded gear rotatably connected to the machine body, a rack slidably connected to the machine body and meshing with the threaded gear, and a push rod fixed to the rack on the side close to the chassis ring, the end of the first connecting rod away from the driven plate is hinged to the end of the screw rod, the threaded gear is threadedly sleeved on the end of the screw rod away from the first connecting rod, and the punching die is provided with a sliding groove slidingly adapted to the push rod.

[0013] By adopting the above technical solution, when the transmission shaft rotates, the driven disk rotates accordingly. At this time, the first connecting rod drives the screw forward or backward, and the threaded gear rotates forward or reversely, thereby pushing the rack to move to the side close to the outer distribution plate or the side close to the inner distribution plate, so that the push rod also moves synchronously, that is, the push rod pushes the workpiece in the punching die into the tapping die through the slide groove, and the moving workpiece to be tapped pushes the tapped workpiece in its forward direction out of the company die to complete the unloading and loading of the tapping die; by setting a suitable screw thread, the rotation stroke and torque of the threaded gear can be changed, that is, when the punching is completed, the workpiece is easy to adhere to the punching die due to burrs or water vapor on the workpiece, and the suitable screw nut can amplify the torque, thereby allowing the workpiece in the punching die to be smoothly pushed out.

[0014] Optionally, the loading assembly includes a loading rod slidably connected to the machine body, a second connecting rod hinged at one end of the loading rod away from the punching die, and a loading tray connected to the transmission shaft, and the end of the second connecting rod away from the loading rod is eccentrically hinged to the end face of the loading tray.

[0015] By adopting the above technical solution, the rotation of the transmission shaft drives the loading plate to rotate, so that the second connecting rod moves, and then the loading rod reciprocates. Since the loading process requires the loading rod to quickly push the workpiece in and then return to prepare for the next push, the movement frequency is high. The simple structure of the loading assembly is more suitable for the rapid reciprocating motion of the push rod, and daily maintenance such as lubrication and maintenance is also relatively simple.

[0016] Optionally, the side wall of the tapping die is provided with a water hole, and two rows of cooling nozzles are arranged on the machine body. The cooling nozzles located in the lower row are directed to the bottom end of the workpiece through the water hole, and the cooling nozzles located in the upper row are located above the tapping die and directed to the top of the workpiece.

[0017] By adopting the above technical solution, during tapping operation, the upper row of cooling nozzles sprays cooling on the upper working area of ​​the workpiece, and the lower row of cooling nozzles sprays cooling on the lower working area of ​​the workpiece through the water permeable holes, thereby reducing the occurrence of sintering, sticking, chipping, etc.

[0018] Optionally, an elastic baffle is fixedly connected to one end of the tapping die away from the push rod, and when the elastic baffle is in a natural state, the elastic baffle fits with the workpiece in the tapping die, and an elastic baffle is also fixedly connected to one end of the punching die located at the punch away from the loading rod.

[0019] By adopting the above technical solution, when the push rod pushes the workpiece into the tapping die, the elastic baffle blocks the workpiece to prevent the workpiece from sliding due to inertia to the tapped part of the workpiece and not aligning with the tap. That is, the elastic baffle on the tapping die effectively reduces the error during tapping. Similarly, the elastic baffle on the punching die also reduces the error of the punching operation.

[0020] Optionally, one end of the tapping die away from the punching die between the two tapping dies is connected to a slideway, and a collecting box with a water filter port is placed at the bottom of the slideway.

[0021] By adopting the above technical solution, after tapping is completed, the push rod pushes the workpiece out of the tapping die, the pushed workpiece enters the slide, and slides into the collection box uniformly, and the coolant on the mold in the collection box is filtered by the water filter on the collection box to reduce the weight of the workpiece during subsequent transportation.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The transmission belt transfers the workpiece to the punching die, the driving assembly drives the loading assembly to make the workpiece enter the punching die, and then the punching arm presses down to make the punch punch a hole on the workpiece, and the waste falls from the waste outlet, and then the punching arm moves up to make the punch separate from the workpiece, and then the chassis ring rotates to the opposite position of the punching die and the tapping die, the driving assembly drives the transfer assembly to move the workpiece to the tapping die on the external material distribution plate, and then the tapping arm drives the tap to perform the tapping operation. During the tapping operation, the chassis ring rotates to drive another punching die to move to the loading assembly for loading and punching operations. After the punching is completed, the chassis ring rotates to make the punch The hole die moves to the position opposite to the tapping die, and then the transfer component moves the workpiece to the tapping die on the inner material distribution plate. At this time, the first punching die moves to the loading component for loading and punching, and then moves to the tapping die on the outer material distribution plate. The transfer component moves the workpiece in the punching die toward the tapping die on the outer material distribution plate, and the moved workpiece pushes out the workpiece in the tapping die, that is, the unloading is completed and the workpiece to be processed in the tapping die is updated at the same time; because the punching operation is shared by two tapping stations, the whole process greatly shortens the waiting time required after each punching operation is completed; 2. When the chassis ring rotates, the active gear ring drives the energy storage gear to rotate, so that the spring on the energy storage gear is tightened. In this process, the energy storage gear drives the one-way gear to rotate, but the one-way gear idles and does not drive the transmission shaft to rotate. When the punching die on the chassis ring moves to the corresponding position, the chassis ring stops for a short time. At this time, the disengagement part disengages the active gear from the meshing connection with the energy storage gear, so that the energy storage gear is driven by the spring and reverses to drive the one-way gear to rotate. At this time, the one-way gear drives the transmission shaft to rotate. The rotating transmission shaft provides a stable rhythmic power source for the transfer component and the drive component. This process does not require the addition of other electronic control hardware equipment and corresponding software algorithms, which greatly saves production costs; 3. When the transmission shaft rotates, the driven plate rotates accordingly. At this time, the first connecting rod drives the screw forward or backward, and the threaded gear rotates forward or reversely, thereby pushing the rack to move to the side close to the outer distribution plate or the side close to the inner distribution plate, so that the push rod also moves synchronously, that is, the push rod pushes the workpiece in the punching die into the tapping die through the slide groove, and the moving workpiece to be tapped pushes the tapped workpiece in its forward direction out of the company die to complete the unloading and loading of the tapping die; by setting a suitable screw thread, the rotation stroke and torque of the threaded gear can be changed, that is, when the punching is completed, the workpiece is easy to adhere to the punching die due to burrs or water vapor on the workpiece, and the suitable screw nut can amplify the torque, thereby allowing the workpiece in the punching die to be smoothly pushed out.

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] The present application embodiment discloses an integrated punching and tapping processing device for automobile parts.

The top of one side of the outer material distribution plate 23 and the top of the side away from the punch 121 are both fixedly connected with a tapping die 32. There are two tapping arms 13, which are respectively located above the two tapping dies 32. Each tapping arm 13 has two taps 131, and one stamping arm 12 has two punches 121. Both ends of the punching die 31 and the tapping die 32 along the radial direction of the chassis ring 21 are open. When the chassis ring 21 is in a stationary state, the two tapping dies 32 and the two punching dies 31 are in a collinear state, and the chassis ring 21 is provided with a waste opening below the punching die 31. The machine body 1 is provided with a transfer component 4 for transferring the workpiece 9 in the punching die 31 located between the two tapping dies 32 to one of the tapping dies 32, and is also provided with a loading component 5 for transferring the workpiece 9 on the conveyor belt 11 to the punching die 31 located under the punch 121. The machine body 1 is also provided with a driving component 6 for driving the transfer component 4 and the loading component 5. In the embodiment of the present application, there are two groups of driving components 6, that is, the two groups of driving components 6 drive the loading component 5 and the transfer component 4 respectively.

[0027] The transmission belt conveys the workpiece 9 to the punching die 31, and the driving component 6 drives the feeding component 5 to make the workpiece 9 enter the punching die 31, and then the punching arm 12 is pressed down to make the punch 121 punch a hole in the workpiece 9, and the waste falls from the waste outlet, and then the punching arm 12 moves up to make the punch 121 separate from the workpiece 9, and then the chassis ring 21 rotates to the position opposite to the punching die 31 and the tapping die 32, and the driving component 6 drives the transfer component 4 to move the workpiece 9 to the tapping die 32 on the external material distribution plate 23, and then the tapping arm 13 drives the tap 131 to perform the tapping operation. During the tapping operation, the chassis ring 21 rotates to drive another punching die 31 to move to the feeding component 5 for feeding and punching operations. After the punching is completed, the chassis ring 2 1 rotates to move the punching die 31 to a position opposite to the tapping die 32, and then the transfer component 4 moves the workpiece 9 to the tapping die 32 on the inner material distribution plate 22. At this time, the first punching die 31 moves to the loading component 5 for loading and punching, and then moves to the tapping die 32 on the outer material distribution plate 23. The transfer component 4 moves the workpiece 9 in the punching die 31 toward the tapping die 32 on the outer material distribution plate 23, and the moved workpiece 9 pushes out the workpiece 9 in the tapping die 32, that is, the unloading is completed and the workpiece 9 to be processed in the tapping die 32 is also updated; because the punching operation is shared by two tapping stations, the whole process greatly shortens the waiting time required after each punching operation is completed.

[0028] Reference Figure 1 and Figure 2 The driving assembly 6 includes a driving gear ring 61 fixed to the peripheral wall of the bottom end of the chassis ring 21, an energy storage gear 62 rotatably connected to the body 1 and meshing with the driving gear ring 61, a clockwork spring 63 arranged on the energy storage gear 62, a one-way gear 64 rotatably connected to the body 1 and a transmission shaft 65 coaxially arranged at the end of the one-way gear 64, the one-way gear 64 is meshingly connected with the energy storage gear 62, when the driving gear ring 61 drives the energy storage gear 62 to rotate, the energy storage gear 62 drives the one-way gear 64 to idle, when When the mainspring 63 drives the energy storage gear 62 to rotate, the one-way gear 64 drives the transmission shaft 65 to rotate synchronously. The driving gear ring 61 is also provided with a disengagement member for disengaging from the meshing with the energy storage gear 62. The disengagement member is a toothless portion 611 provided on the driving gear ring 61. There are two toothless portions 611. When the punching die 31 moves to face the tapping die 32, the toothless portion 611 on the driving gear ring 61 faces the energy storage gear 62. The driving assembly 6 also includes a reduction box 66 connected to the output end of the transmission shaft 65.

[0029] When the chassis ring 21 rotates, the active gear ring 61 drives the energy storage gear 62 to rotate, so that the spring 63 on the energy storage gear 62 is tightened. In this process, the energy storage gear 62 drives the one-way gear 64 to rotate, but the one-way gear 64 idles and does not drive the transmission shaft 65 to rotate. When the punching die 31 on the chassis ring 21 moves to the corresponding position, the toothed portion 611 on the active gear ring 61 is opposite to the energy storage gear 62, so that the active gear ring 61 is disengaged from the energy storage gear 62, and the chassis ring 21 is temporarily stationary. The clutch disengages the driving gear from the meshing connection with the energy storage gear 62, so that the energy storage gear 62 is driven by the mainspring 63 to reverse, thereby driving the one-way gear 64 to rotate. At this time, the one-way gear 64 drives the transmission shaft 65 to rotate, and then the reduction box 66 receives the power transmitted by the transmission shaft 65. After the speed change of the reduction box 66, the reduction box 66 provides a power source with a stable rhythm for the transfer component 4 and the drive component 6. This process does not require the addition of other hardware equipment such as electronic control and corresponding software algorithms, which greatly saves production costs.

[0030] Reference Figure 2 and Figure 4 The end of the transmission shaft 65 located in the one-way gear 64 is elastically hinged with a one-way block 651. The one-way gear 64 includes an outer tooth portion 641 meshing with the energy storage gear 62 and a ratchet portion 642 meshing with the one-way block 651. When the one-way block 651 is in a free state, the one-way block 651 and the ratchet portion 642 are in a meshing state. When the one-way gear 64 is indirectly driven by the active gear ring 61, the ratchet portion 642 squeezes the one-way block 651, and the one-way block 651 reciprocates due to elasticity. At this time, the ratchet portion 642 cannot push the one-way block 651. When the one-way gear 64 is indirectly driven to rotate by the spring 63, due to the change in the rotation direction, the ratchet portion 642 pushes the one-way block 651 to rotate, thereby rotating the transmission shaft 65.

[0031] Reference Figure 2 and Figure 3 The transfer assembly 4 includes a driven plate 41 connected to the reduction box 66 through a synchronous belt, a first connecting rod 42 eccentrically hinged on the end face of the driven plate 41, a screw rod 43 slidably connected to the body 1, a threaded gear 44 rotatably connected to the body 1, a rack 45 slidably connected to the body 1 and meshing with the threaded gear 44, and a push rod 46 fixed to the rack 45 near the chassis ring 21. The end of the first connecting rod 42 away from the driven plate 41 is hinged to the end of the screw rod 43, and the threaded gear 44 is threadedly sleeved on the end of the screw rod 43 away from the first connecting rod 42. The punching die 31 is provided with a slide groove 311 that is slidably adapted to the push rod 46.

[0032] When the transmission shaft 65 rotates, the driven disk 41 rotates accordingly. At this time, the first connecting rod 42 drives the screw rod 43 forward or backward, and the threaded gear 44 rotates forward or reversely, thereby pushing the rack 45 to move to the side close to the outer distribution plate 23 or the side close to the inner distribution plate 22, so that the push rod 46 also moves synchronously, that is, the push rod 46 pushes the workpiece 9 in the punching die 31 into the tapping die 32 through the slide groove 311, and the moving workpiece 9 to be tapped pushes the tapped workpiece 9 in its forward direction out of the company die to complete the unloading and loading of the tapping die 32. At the same time, by setting a suitable screw rod 43 thread, the rotation stroke and torque of the threaded gear 44 can be changed, that is, when the punching is completed, the workpiece 9 is easy to adhere to the punching die 31 due to burrs or water vapor on the workpiece 9, and the suitable screw rod 43 nut can amplify the torque, thereby allowing the workpiece 9 in the punching die 31 to be smoothly pushed out.

[0033] Reference Figure 1 and Figure 2 The feeding assembly 5 includes a feeding rod 51 slidably connected to the machine body 1, a second connecting rod 52 hinged at one end of the feeding rod 51 away from the punching die 31, and a feeding plate 53 connected to the reduction box 66 through a synchronous belt, and one end of the second connecting rod 52 away from the feeding rod 51 is eccentrically hinged to the end surface of the feeding plate 53. The rotation of the reduction box 66 drives the feeding plate 53 to rotate, so that the second connecting rod 52 moves, and then the feeding rod 51 reciprocates. Since the feeding process requires the feeding rod 51 to quickly push the workpiece 9 in, and then retreat to prepare for the next push, the movement frequency is high, and the simple structure of the feeding assembly 5 is more suitable for the rapid reciprocating movement of the push rod 46, and the daily maintenance such as lubrication and repair is also relatively simple.

[0034] Reference Figure 1 and Figure 2 A water-permeable hole 321 is provided on the side wall of the tapping die 32, and two rows of cooling nozzles 14 are provided on the machine body 1, with four in each row, that is, one company mold corresponds to two rows of four cooling nozzles 14, and the cooling nozzles 14 in the lower row point to the bottom end of the workpiece 9 through the water-permeable hole 321, and the cooling nozzles 14 in the upper row are located above the tapping die 32 and point to the top of the workpiece. One end of the tapping die 32 away from the punching die 31 between the two tapping dies 32 is connected to a slide 81, and a collecting box 82 with a water filter port is placed at the bottom of the slide 81. During the tapping operation, the upper row of cooling nozzles 14 spray cool the upper working area of ​​the workpiece 9, and the lower row of cooling nozzles 14 spray cool the lower working area of ​​the workpiece 9 through the water permeable holes 321, thereby reducing the occurrence of sintering, sticking, chipping, etc.; after the tapping is completed, the push rod 46 pushes the workpiece 9 out of the tapping die 32, and the pushed workpiece 9 enters the slide 81 and slides into the collection box 82 uniformly, and the coolant on the mold in the collection box 82 is filtered by the water filter on the collection box 82 to reduce the weight of the subsequent transportation of the workpiece 9.

[0035] Reference Figure 1 and Figure 3 The end of the tapping die 32 away from the push rod 46 is fixedly connected with an elastic baffle 7, which can be made of rubber or spring steel. In the present application, the elastic baffle 7 is made of spring steel with a low friction coefficient and is more durable. When the elastic baffle 7 is in a natural state, the elastic baffle 7 fits the workpiece 9 in the tapping die 32, and the end of the punching die 31 located at the punch 121 away from the feeding rod 51 is also fixedly connected with an elastic baffle 7. When the push rod 46 pushes the workpiece 9 into the tapping die 32, the elastic baffle 7 blocks the workpiece 9 and prevents the workpiece 9 from sliding to the tapped part of the workpiece 9 due to inertia and not being aligned with the tap 131, that is, the elastic baffle 7 on the tapping die 32 effectively reduces the error during tapping. Similarly, the elastic baffle 7 on the punching die 31 also reduces the error of the punching operation.

[0036] The implementation principle of the punching and tapping integrated processing equipment for automobile parts in the embodiment of the present application is as follows: when the chassis ring 21 rotates, the active gear ring 61 drives the energy storage gear 62 to rotate, so that the spring 63 on the energy storage gear 62 is tightened to store energy. During this process, the energy storage gear 62 drives the one-way gear 64 to rotate, but the one-way gear 64 idles and does not drive the transmission shaft 65 to rotate; When the chassis ring 21 rotates to make the punching die 31 and the tapping die 32 relatively aligned, the chassis ring 21 stops for a short time, and the disengagement member disengages the driving gear from the meshing connection with the energy storage gear 62, so that the energy storage gear 62 is driven by the spring 63 to reverse, thereby driving the one-way gear 64 to rotate, and the one-way gear 64 drives the transmission shaft 65 to rotate. At this time, the reduction box 66 drives the driven plate 41 to rotate, and the first connecting rod 42 drives the screw rod 43 to move forward or backward, and the threaded gear 44 rotates forward or reversely accordingly, thereby pushing the rack 45 to approach the outer material distribution plate 2 3 or the side close to the inner distribution plate 22 moves, so that the push rod 46 also moves synchronously, that is, the push rod 46 pushes the workpiece 9 in the punching die 31 into the tapping die 32 through the slide groove 311, and the moving workpiece 9 to be tapped pushes the tapped workpiece 9 in its forward direction out of the company die to complete the unloading and loading of the tapping die 32, and at the same time the reduction box 66 drives the loading plate 53 to rotate, so that the second connecting rod 52 moves, and then the loading rod 51 makes a reciprocating motion to push the workpiece 9 into the punching die 31 and then withdraw it.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
