Description

Technical Field

[0001] The present application relates to the technical field of metal processing, and in particular to a non-cutting punching device for mechanical metal processing. Background Art

[0002] Stamping is a production technology that uses the power of conventional or special stamping equipment to apply external force to metal materials such as plates, strips, pipes and profiles, so that the metal materials are directly subjected to deformation force in the mold and produce plastic deformation or separation, realizing the non-cutting plasticity of mechanical metals, thereby obtaining product parts of a certain shape, size and performance.

[0003] In the prior art, when a stamping machine stamps mechanical metal, the workpiece is often completed by manually placing the mechanical metal sheet and manually demolding and stamping. This makes it easy for workers to become fatigued after working for a long time. When working in a tired state, their reactions are slow and they are easily accidentally injured by the stamping machine, causing personal injury. Summary of the Invention

[0004] In order to increase the safety of mechanical metal non-cutting stamping, the present application provides a non-cutting stamping device for mechanical metal processing.

[0005] The present application provides a non-cutting punching device for mechanical metal processing, which adopts the following technical solution: the punching device includes a punching table, a punching head and a cylinder driving the punching head for punching, a punching groove for punching metal sheets, and a demoulding rod rotatably arranged in the punching table, the demoulding rod rotating in and out of the bottom of the punching groove;

[0006] A feeding table is provided with a feeding mechanism, which is used to feed the metal sheet into the stamping groove. A driving member for driving the demoulding rod to rotate is provided on the feeding table.

[0007] By adopting the above technical solution, when stamping metal sheets, the metal sheets are placed on the feeding table, and the metal sheets are transported to the stamping groove by the feeding mechanism, and then the stamping table is driven by the cylinder to stamp the metal sheets in the stamping groove, and finally the demolding rod is driven by the driving part to demold, so as to realize the automatic feeding and stamping of the metal sheets and demolding after stamping, replacing the manual work of placing the metal sheets and taking up the stamped sheets, reducing the safety hazards in the stamping process, and thus increasing the safety of mechanical metal non-cutting stamping.

[0008] Optionally, the driving member includes a transmission plate slidably arranged in the stamping table, the transmission plate slides horizontally below the demolding rod, the lower end of the demolding rod is hinged to the transmission plate, and the middle section of the demolding rod is hinged in the stamping table, the transmission plate slides away from one end of the demolding rod and passes through the side of the stamping table toward the feeding table, the initial state of the demolding rod is that the upper end is inclined toward the feeding table, and the top end of the demolding rod forms part of the bottom of the stamping groove.

[0009] By adopting the above technical solution, when the stamped metal sheet is demolded, the transmission plate is slid toward the feed table, so that the transmission plate drives the lower end of the demolding rod to rotate toward the feed table, and then the upper end of the demolding rod rotates toward the feed table, so that the upper end of the demolding rod is rotated into the stamping groove to lift the metal sheet from the bottom of the metal sheet, so as to realize automatic demolding of the metal sheet after stamping, thereby avoiding direct demolding from the stamping groove, and moving the demolding action to the outside of the stamping table, which helps to improve the safety of the demolding rod action.

[0010] Optionally, a pair of feed rods are hingedly connected to one end of the feed table close to the punching table, and a feed roller is rotatably provided on the upper end of the feed rod and is located between the pair of feed rods. The height of the feed roller is higher than the upper surface of the punching table, and the transmission plate slides into the feed table at one end away from the punching table, and the lower end of the feed rod is hinged to the upper surface of the transmission plate. The initial states of the feed rod and the demolding rod are the same and are both inclined toward the direction of the feeding mechanism. A first spring is provided between the feed table and the feed rod, and the tension of the first spring acts on the feed rod to drive the feed rod to return to its initial state.

[0011] By adopting the above technical solution, when the feeding mechanism conveys the metal sheet toward the punching table, the metal sheet first contacts the feeding rod, and the feeding rod is abutted to drive the feeding roller to rotate toward the punching table to stretch the first spring; then the lower end of the feeding rod is rotated in a direction away from the punching table to drive the transmission plate to slide into the feeding table, and then the lower end of the stripper rod is rotated in the direction of the feeding table to realize the upper end of the stripper rod rotating in a direction away from the feeding table and automatically demoulding; until the metal sheet is conveyed into the punching groove of the punching table by the rotation of the feeding roller, the feeding rod is disengaged from the abutment of the metal sheet and resets under the tension of the first spring, and then drives the feeding rod to rotate toward the feeding mechanism to restore to the initial state, and then drives the stripper rod to rotate to the initial position through the transmission plate. In this way, the feeding rod is driven by the conveying of the metal sheet, and the force of the metal sheet conveying is transmitted to the stripper rod through the power transmission of the transmission plate, so that the stripper rod automatically rotates to demould the stamped metal sheet, which is helpful to realize automatic feeding and automatic demoulding.

[0012] Optionally, a receiving groove for the transmission plate to slide into is provided on the feeding table, and a sliding groove for the transmission plate to slide is provided in the stamping table, and the groove widths of the receiving groove and the sliding groove in the vertical direction are both greater than the thickness of the transmission plate.

[0013] By adopting the above technical solution, when the feeding rod is pushed by the metal plate, it drives the transmission plate to slide in the receiving groove, so that the transmission plate can slide horizontally in the receiving groove and swing vertically in a small range at the same time, so that the rotation of the feeding rod and the demolding rod can be synchronized, thereby helping to drive the demolding rod and the feeding rod to rotate synchronously.

[0014] Optionally, a receiving roller is rotatably provided on one side of the punching table toward the feeding table. The receiving roller is rotatably provided at the upper end of the punching table. The height of the receiving roller is lower than the height of the feeding roller. The receiving roller is used to receive the metal sheet into the punching groove.

[0015] By adopting the above technical solution, after the metal sheet passes through the receiving roller, the metal sheet slides into the stamping groove under the support of the receiving roller, which helps to transport the metal sheet conveyed by the feeding mechanism into the stamping groove and improves the accuracy of conveying the metal sheet into the stamping groove.

[0016] Optionally, the end of the receiving roller is coaxially connected to a gear, and a receiving gear rod is vertically slidably provided in the feeding platform, and the upper end of the receiving gear rod is engaged with the gear.

[0017] By adopting the above technical solution, when the metal sheet is conveyed to the receiving roller, the receiving gear rod slides up, and the receiving gear rod drives the receiving roller to rotate toward the stamping groove through the gear, so that the metal sheet is automatically conveyed to the stamping groove through the rotating receiving roller, thereby further ensuring the accuracy of the metal sheet entering the stamping groove after leaving the feeding mechanism.

[0018] Optionally, one end of the receiving gear rod located in the feeding platform is connected to a fixed block, and an inner cavity groove is provided in the feeding platform for the fixed block to slide along the vertical direction with the receiving gear rod. The receiving gear rod is provided with a second spring located below the fixed block, and the upper end of the second spring is connected to the fixed block and the lower end is connected to the bottom of the inner cavity groove. When the receiving gear rod slides down and disengages from the gear, the receiving gear rod compresses the second spring so that the upper end of the receiving gear rod remains disengaged from the gear.

[0019] By adopting the above technical solution, when the metal sheet is conveyed to the receiving roller through the feeding mechanism, the receiving gear rod moves down, causing the second spring to stretch; then the receiving gear rod is released, causing the receiving gear rod to slide upward under the tension of the second spring, thereby driving the gear to rotate clockwise, and then driving the receiving roller to rotate clockwise, so that the receiving roller rotates toward the stamping groove, thereby helping the receiving gear rod to slide up automatically.

[0020] Optionally, the upper end of the material receiving gear rod is meshed with the side of the gear close to the feeding platform, and the lower end of the material receiving gear rod slides through the feeding platform and has a wedge-shaped portion, and the transmission plate is provided with a through slot for the wedge-shaped portion to slide into, and the slot wall of the through slot close to the feeding platform is an abutment inclined surface. When the transmission plate slides toward the stamping platform, the abutment inclined surface pushes the wedge-shaped portion to drive the material receiving gear rod to slide up, and the second spring is stretched, thereby driving the material receiving roller to rotate toward the direction of the stamping slot. The through slot allows the transmission plate to slide horizontally relative to the wedge-shaped portion. When the transmission plate slides toward the feeding platform, the upper end of the material receiving gear rod slides down and disengages from the gear under gravity, and the lower end slides into the through slot, and remains disengaged from the gear under the elastic force of the second spring.

[0021] By adopting the above technical solution, when the metal sheet is conveyed to the receiving roller through the feeding mechanism, the metal sheet pushes the feeding rod, driving the transmission plate to slide toward the feeding table, so that the abutting inclined surface of the through groove in the transmission plate disengages from the abutting part of the receiving gear rod, so that the receiving gear rod slides down due to gravity and disengages from the gear. The receiving gear rod compresses the second spring so that the upper end of the receiving gear rod remains disengaged from the gear. Until the demoulding rod pushes the stamped metal sheet out of the stamping groove, the new metal sheet is separated from the feeding rod and transported to the receiving roller. The feeding rod is separated from the abutment of the metal sheet and resets to the initial state under the action of the first spring tension, and then the transmission plate drives the demoulding rod to reset to the first initial state; the transmission plate slides toward the stamping table at this time, so that the abutment inclined surface in the transmission plate groove pushes the wedge-shaped part to slide up, and then pushes the receiving gear rod to slide up and engage with the gear, driving the receiving roller to rotate toward the stamping groove, so that the metal sheet separated from the feeding mechanism can continue to rotate toward the stamping groove under the relay of the rotating receiving roller, so as to improve the accuracy of feeding the metal sheet into the stamping groove. In this way, by using the wedge-shaped part of the receiving gear rod and the abutting inclined surface of the through groove, and utilizing the horizontal sliding of the transmission plate, the receiving gear rod can be disengaged from the gear and the demoulding rod can be demolded when the metal sheet is not delivered to the receiving roller; when the metal sheet is delivered to the receiving roller, the receiving gear rod engages the gear, driving the receiving roller to rotate and deliver the metal sheet for a second time, thereby improving the accuracy of the metal sheet being delivered to the stamping groove in one time.

[0022] Optionally, the feeding mechanism includes a first conveying component and a second conveying component, the first conveying component includes a pair of first fixed plates arranged side by side and a plurality of first conveying rollers rotatably arranged between the first fixed plates, the second conveying component includes a pair of second fixed plates arranged side by side, a plurality of second conveying rollers rotatably arranged between the second fixed plates, and a driving motor for driving one of the second conveying rollers to rotate, the ends of the rotating shafts of the plurality of second conveying rollers are connected by a gear chain, the second fixed plate is fixed on the feeding table, the height of the second conveying roller is lower than the height of the feeding roller, the first conveying component is arranged above the second conveying component by an elastic telescopic member, and the first conveying component and the second conveying component have an extrusion force approaching each other.

[0023] By adopting the above technical solution, when the metal sheet is fed through the feeding mechanism, the driving motor drives the second conveyor roller to rotate, so as to drive multiple second conveyor rollers to rotate simultaneously through the tooth chain, so that the metal sheet clamped between the first conveyor roller and the second conveyor roller by the elastic telescopic member can be transported to the feeding rod and the feeding roller under the rotation of the second conveyor roller, and then the feeding rod is driven to rotate, thereby realizing automatic feeding of the metal sheet, and providing power for the rotation of the feeding rod and the demolding rod.

[0024] Optionally, the elastic telescopic member includes a plurality of connecting columns arranged between the first fixed plate and the second fixed plate, the lower end of the connecting column is fixed to the second fixed plate, and the upper end is slidably arranged on the first fixed plate, and a telescopic spring is sleeved on the connecting column, the lower end of the telescopic spring is fixed to the second fixed plate, and the upper end is fixed to the bottom wall of the first fixed plate. When the metal sheet enters between the first conveying roller and the second conveying roller, the tension of the telescopic spring acts on the first fixed plate.

[0025] By adopting the above technical solution, the tension of the telescopic spring acts on the connecting column, causing the connecting column to slide toward the first fixed plate, thereby driving the first conveying roller and the second conveying roller to move toward each other, thereby facilitating the clamping of the metal sheet between the first conveying roller and the second conveying roller.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] It can realize the automatic feeding and demoulding of metal sheets after stamping, replacing the manual work of placing metal sheets and taking out the stamped sheets, reducing the safety hazards in the stamping process, and thus increasing the safety of mechanical metal non-cutting stamping;

The demolding rod 15 rotates in and out of the bottom of the stamping groove 13. A feeding mechanism 3 is provided on the feeding table 2. The feeding mechanism 3 is used to feed the metal sheet into the stamping groove 13, and a driving part 4 is provided on the feeding table 2 to drive the demolding rod 15 to rotate.

[0037] In this embodiment, a punching frame 14 is provided on the punching table 1. The cylinder 12 and punch head 11 are both mounted on top of the punching frame 14. The piston rod of the cylinder 12 passes through the top of the punching frame 14 and is connected to the punch head 11, driving the punch head 11 to slide vertically. Four ejector rods 15 are provided within the punching table 1. Each ejector rod 15 is arranged in parallel, and the ejector rods 15 are evenly distributed in pairs within the punching slot 13. The driver 4 is provided on the feed table 2 and the punching table 1.

[0038] In some embodiments, the feeding mechanism 3 includes a first conveying assembly 31 and a second conveying assembly 32. The first conveying assembly 31 includes a pair of first fixed plates 311 arranged side by side and a plurality of first conveying rollers 312 rotatably arranged between the first fixed plates 311. The second conveying assembly 32 includes a pair of second fixed plates 321 arranged side by side, a plurality of second conveying rollers 322 rotatably arranged between the second fixed plates 321, and a driving motor 323 for driving one of the second conveying rollers 322 to rotate. The ends of the rotating shafts of the plurality of second conveying rollers 322 are connected by a gear chain. The second fixed plate 321 is fixed to the feeding table 2. The first conveying assembly 31 is arranged above the second conveying assembly 32 by an elastic telescopic member. The first conveying assembly 31 and the second conveying assembly 32 have an extrusion force that approaches each other.

[0039] In this embodiment, two first fixed plates 311 are provided. A plurality of first conveyor rollers 312 rotate between the first fixed plates 311, with each first conveyor roller 312 having two ends rotatably connected to the two first fixed plates 311. The first conveyor rollers 312 are spaced apart along the length of the first fixed plates 311. Two second fixed plates 321 are provided, corresponding one-to-one with each first fixed plate 311. A plurality of second conveyor rollers 322 rotate between the second fixed plates 321, with each second conveyor roller 322 having two ends rotatably connected to the two second fixed plates 321. The second conveyor rollers 322 are spaced apart along the length of the second fixed plates 321. The second conveyor rollers 322 are provided in a one-to-one correspondence with the first conveyor rollers 312. The driving motor 323 is fixed on the feeding table 2, and each second conveying roller 322 has a sprocket at the end, which is connected by a tooth chain. After the driving motor 323 drives one second conveying roller 322 to rotate, it drives multiple second conveying rollers 322 to rotate synchronously, so as to facilitate the transportation of metal sheets between the first conveying roller 312 and the second conveying roller 322.

[0040] In some embodiments, the elastic expansion member includes a plurality of connecting posts 33 disposed between a first fixed plate 311 and a second fixed plate 321. The lower ends of the connecting posts 33 are fixed to the second fixed plate 321, and the upper ends are slidably disposed on the first fixed plate 311. A telescopic spring 331 is sleeved on the connecting posts 33. The lower ends of the telescopic springs 331 are fixed to the second fixed plate 321, and the upper ends are fixed to the bottom wall of the first fixed plate 311. When the metal sheet enters between the first conveyor roller 312 and the second conveyor roller 322, the tension of the telescopic springs 331 acts on the first fixed plate 311.

[0041] In this embodiment, the first and second fixing plates 311, 321 are connected by connecting posts 33 to guide the sliding movement between the first and second fixing plates 311, 321, and prevent misalignment when the first and second fixing plates 311, 321 slide toward each other. A telescopic spring 331 is mounted outside the connecting posts 33 to provide a force pulling the first and second fixing plates 311, 321 toward each other.

[0042] In some embodiments, the drive member 4 includes a transmission plate 41 slidably disposed within the punching table 1. The transmission plate 41 slides horizontally below the ejector rod 15. The lower end of the ejector rod 15 is hinged to the transmission plate 41, and the middle section of the ejector rod 15 is hinged within the punching table 1. The end of the transmission plate 41 away from the ejector rod 15 slides through the side of the punching table 1 facing the feed table 2. In the initial state, the ejector rod 15 is tilted with its upper end toward the feed table 2, and the top end of the ejector rod 15 forms a portion of the bottom of the punching groove 13.

[0043] In this embodiment, one end of the transmission plate 41 slides within the punching table 1, while the other end slides within the feed table 2. The axis of the hinged axis of the ejector rod 15 is perpendicular to the direction of conveyance of the metal sheet. A rotation slot 16 is defined within the punching table 1 for the ejector rod 15 to rotate. The upper notch of the rotation slot 16 communicates with the bottom of the punching slot 13, allowing the upper end of the ejector rod 15 to pivot from the rotation slot 16 into the punching slot 13, lifting the stamped metal sheet and releasing it from the mold.

[0044] In some embodiments, the driving member 4 also includes a pair of feed rods 42 hinged at one end of the feed table 2 close to the punching table 1. A feed roller 421 is rotatably provided at the upper end of the feed rod 42 and is located between the pair of feed rods 42. The height of the feed roller 421 is higher than the upper surface of the punching table 1, and the transmission plate 41 slides through the end away from the punching table 1 into the feed table 2. The lower end of the feed rod 42 is hinged to the upper surface of the transmission plate 41. The initial state of the feed rod 42 and the demolding rod 15 is the same, both are tilted toward the direction of the feeding mechanism 3, and a first spring 422 is provided between the feed table 2 and the feed rod 42. The tension of the first spring 422 acts on the feed rod 42 to drive the feed rod 42 to return to its initial state.

[0045] In this embodiment, the height of the feed roller 421 is higher than the height of the second conveying roller 322. The length of the feed roller 421 is smaller than that of the first conveying roller 312 and the second conveying roller 322. The metal sheet first abuts against the feed rod 42 before abutting against the feed roller 421. A feed trough 21 for the feed rod 42 to rotate is provided on the feed table 2 near the punching table 1. One end of the first spring 422 is fixed to the trough wall of the feed trough 21 facing the punching table 1, and the other end is fixed to the side wall of the feed rod 42 facing the second conveying roller 322. The tension of the first spring 422 makes the initial states of the feed rod 42 and the demolding rod 15 the same and arranged in parallel. The hinge axes of the feed rod 42 and the demolding rod 15 are parallel. In the feed table 2, the lower end of the feed rod 42 is hinged to the upper surface of the transmission plate 41.

[0046] For example, the feed table 2 is provided with a receiving groove 22 for the transmission plate 41 to slide into, and the punching table 1 is provided with a slide groove 17 for the transmission plate 41 to slide into. The vertical widths of the receiving groove 22 and the slide groove 17 are both greater than the thickness of the transmission plate 41. The feed trough 21 and the receiving groove 22 are connected, and the end of the transmission plate 41 located in the feed table 2 is always located in the receiving groove 22.

[0047] In some embodiments, a receiving roller 18 is rotatably provided on one side of the punching table 1 facing the feeding table 2. The receiving roller 18 is rotatably provided at the upper end of the punching table 1. The height of the receiving roller 18 is lower than that of the feeding roller 421, and the receiving roller 18 is used to receive the metal sheet into the punching slot 13.

[0048] In this embodiment, the receiving roller 18 is rotatably mounted on the side wall of the punching table 1. The receiving roller 18 and the second transfer roller 322 are arranged at the same height and parallel to each other, and have the same length. The axis of the receiving roller 18 is higher than the height of the notch of the punching slot 13. When the metal sheet pushes against the feed rod 42, driving the feed roller 421 to rotate toward the punching table 1, the feed roller 421 is at the same height as the receiving roller 18 and is arranged opposite to it. The receiving roller 18 is located outside the rotation path of the feed roller 421.

[0049] In some embodiments, reference Figure 2 and Figure 3 The end of the receiving roller 18 is coaxially connected to the gear 181, and a receiving gear rod 23 is provided in the feeding platform 2 for vertical sliding. The upper end of the receiving gear rod 23 is engaged with the gear 181. One end of the receiving gear rod 23 located in the feeding platform 2 is connected to a fixed block 231. An inner cavity groove 24 is provided in the feeding platform 2 for the fixed block 231 to slide along the vertical direction with the receiving gear rod 23. The receiving gear rod 23 is provided with a second spring 232 located below the fixed block 231. The upper end of the second spring 232 is connected to the fixed block 231 and the lower end is connected to the bottom of the inner cavity groove 24. When the receiving gear rod 23 slides down and disengages from the gear 181, the receiving gear rod 23 compresses the second spring 232, so that the upper end of the receiving gear rod 23 remains disengaged from the gear 181.

[0050] In this embodiment, because the length of the receiving roller 18 is the same as that of the second conveyor roller 322, the gear 181 is located on both sides of the metal sheet conveying path. The fixing block 231 slides vertically within the inner groove 24. The lower end of the receiving gear rod 23 penetrates the receiving groove 22. In the initial state of the feed rod 42 and the demolding rod 15, the second spring 232 is extended, and the upper end of the receiving gear rod 23 engages with the gear 181.

[0051] For example, the upper end of the receiving gear rod 23 engages with the side of the gear 181 near the feed table 2, and the lower end of the receiving gear rod 23 slides through the feed table 2 and has a wedge-shaped portion 233. The transmission plate 41 has a through slot 411 for the wedge-shaped portion 233 to slide into, and the slot wall of the through slot 411 near the feed table 2 is an abutment slope 412. When the transmission plate 41 slides toward the punching table 1, the contact inclined surface 412 pushes the wedge-shaped part 233 to drive the material receiving gear rod 23 to slide up, and the second spring 232 is stretched, thereby driving the material receiving roller 18 to rotate toward the direction of the punching groove 13, and the through groove 411 allows the transmission plate 41 to slide horizontally relative to the wedge-shaped part 233; when the transmission plate 41 slides toward the feeding table 2, the material receiving gear rod 23 slides down and disengages from the gear 181 under the force of gravity, and the lower end slides into the through groove 411, and remains disengaged from the gear 181 under the elastic force of the second spring 232.

[0052] In this embodiment, in the initial state of the feed rod 42 and the stripper rod 15, the wedge-shaped portion 233 at the lower end of the receiving gear rod 23 abuts against the abutting inclined surface 412 of the through groove 411. When the feed rod 42 is in the feeding state tilted toward the punching table 1 and the stripper rod 15 is in the demolding state tilted away from the feed table 2, part of the metal sheet is located on the feed roller 421 and the other part is located on the receiving roller 18. The receiving gear rod 23 slides down and disengages from the gear 181, and the second spring 232 is compressed. The wedge-shaped portion 233 of the receiving gear rod 23 disengages from the abutting inclined surface 412 and is located in the through groove 411. After the metal sheet is completely located on the receiving roller 18, the feed rod 42 and the stripper rod 15 are reset, and the transmission plate 41 slides into the feed table 2 to abut the receiving gear rod 23 upward, driving the receiving roller 18 to rotate toward the punching groove 13, thereby performing a secondary conveyance of the metal sheet and ensuring that the metal sheet can be accurately conveyed into the punching groove 13.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
