High-continuity metal plate processing device

Abstract

This invention provides a high-continuity metal sheet processing device. A drive cylinder drives a mounting frame, a pusher frame, and a punching assembly to reciprocate upwards and downwards. During this reciprocating motion, the pusher frame, in conjunction with an elastic mechanism, drives a transmission rod to move back and forth. This movement of the transmission rod, through a transmission mechanism, drives a slide to move back and forth. Because the limiting rollers on the frame and slide, in conjunction with a ratchet mechanism, provide unidirectional fixation to the metal sheet, the metal sheet can only move to the right. The slide can only drag the metal sheet forward when it moves to the right. That is, each reciprocating movement of the slide pushes the metal sheet forward a certain distance, achieving continuous material feeding. Furthermore, the height of the pusher frame relative to the transmission rod can be adjusted via an adjustable distance mechanism, thereby adjusting the length of material conveyed by the slide in a single operation. This allows operators to adjust the hole spacing on the metal sheet as needed, saving labor costs, ensuring high work continuity, and providing convenience for punching operations.

Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and more specifically to a high-continuity metal plate processing apparatus. Background Technology

[0002] Metal sheet processing involves various processes, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming. Stamping, as a common metal sheet processing technology, mainly uses the cutting edge of a die to shear and deform the sheet material along a certain contour line, separating it into parts or blanks of the required shape and size. Currently, punching metal sheets involves positioning the raw material and then, driven by a power mechanism, using a punch to penetrate the sheet to achieve the punching effect. This usually requires manual assistance in loading and unloading the material next to the equipment, which is time-consuming, labor-intensive, and lacks continuity, resulting in low overall punching efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing a highly continuous metal sheet processing apparatus, thereby solving the problems described above.

[0007] A drive cylinder is mounted on the frame. The piston rod of the drive cylinder is provided with a mounting bracket and a punching assembly for punching holes in a metal plate. A pusher is movably mounted on the mounting bracket to push the transmission rod to move. An adjustment mechanism is provided on the mounting bracket to adjust the distance between the pusher and the mounting bracket.

[0008] An elastic mechanism is provided on the frame and can act on the transmission rod to drive the transmission rod to extend relative to the frame.

[0009] The limiting roller assembly is provided on both the frame and the slide. The limiting roller assembly includes a pair of rotating rollers. The pair of rotating rollers are rotatably mounted on both the frame and the slide. The two rotating rollers in the pair are located on the upper and lower sides of the metal plate and are in close contact with the metal plate. The frame and the slide are provided with a ratchet mechanism. The ratchet mechanism can act on the rotating rollers to make the rotating rollers rotate only in one direction, so that the metal plate can only be conveyed unidirectionally along the frame.

[0010] Preferably, the limiting roller group further includes a pair of mounting plates, the rotating rollers are rotatably mounted on the mounting plates, and the two mounting plates are fastened together by bolts to drive the two rotating rollers to adhere tightly to the metal plate from the upper and lower sides.

[0011] Preferably, the ratchet assembly consists of a ratchet, a pawl, and a torsion spring. The ratchet is coaxially arranged with the rotating roller and can rotate synchronously. The pawl is rotatably mounted on the mounting plate. The torsion spring can act on the pawl to drive the pawl to elastically abut against the ratchet. The pawl can cooperate with the ratchet so that the rotating roller can only rotate in one direction.

[0012] Preferably, the transmission mechanism includes a vertical rack, a first gear, a second gear, and a horizontal rack. The vertical rack is connected to the transmission rod. The first gear is provided with a transmission shaft for coaxial connection with the second gear. The transmission shaft is rotatably mounted on the frame. The first gear meshes with the vertical rack, the second gear meshes with the horizontal rack, and the horizontal rack is connected to the slide and can drive the slide to move.

[0013] Preferably, the elastic mechanism includes a mounting cylinder, a return spring, and a moving rod. The mounting cylinder is disposed on the frame, the moving rod is movably mounted on the mounting cylinder, the moving rod is connected to the transmission rod, and the return spring is installed in the inner cavity of the mounting cylinder. The return spring can push against the moving rod to drive the transmission rod to extend relative to the frame.

[0014] Preferably, the punching assembly includes a mounting base, a pressure plate, an elastic element, and a punch. The mounting base is movably mounted on the frame and connected to the piston rod of the drive cylinder. The punch is disposed on the mounting base. The pressure plate is movably mounted on the mounting base. The pressure plate has a through hole for the punch to pass through. The elastic element can act on the pressure plate to drive the pressure plate to extend relative to the mounting base.

[0015] Preferably, the pressure plate is provided with a mounting post, the mounting base is provided with a mounting hole for the mounting post to be moved and installed, the mounting post is provided with a contact plate that can abut against the mounting base, the elastic element is a compression spring, the compression spring is sleeved on the mounting post, and the compression spring can push the pressure plate to make the contact plate abut against the mounting base.

[0016] Preferably, the mounting base is provided with a cutter for cutting metal plates.

[0017] Preferably, the adjusting mechanism includes a drive motor and a screw. The drive motor is mounted on the mounting frame and is connected to the screw in a transmission manner, enabling the screw to rotate. The push frame is provided with a screw hole that mates with the screw.

[0018] Preferably, a rubber sleeve is fitted around the outer periphery of the roller.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] During operation, the drive cylinder lowers the mounting frame, push frame, and punching assembly. The punching assembly punches holes in the metal plate on the frame. As the push frame descends, it pushes the transmission rod, which, through a transmission mechanism, drives the slide to the left, away from the punching assembly. During this leftward movement, the limit rollers on the frame, in conjunction with a ratchet mechanism, unidirectionally fix the metal plate, allowing it to move only to the right. At this time, the rotating rollers on the slide rotate and move forward relative to the metal plate. When the drive cylinder raises the push frame, the elastic mechanism causes the transmission rod to reset upwards and, through the transmission mechanism, drives the slide... As the slide moves to the right near the punching assembly, the rollers on the slide cannot rotate due to the ratchet mechanism. Under the action of friction, the metal plate moves to the right, thus feeding material into the punching assembly. During the reciprocating drive of the drive cylinder, continuous feeding and continuous punching can be achieved. Furthermore, the height position of the push frame relative to the transmission rod can be adjusted by the distance adjustment mechanism, thereby adjusting the length of material conveyed by the slide in a single operation. This allows the operator to adjust the hole spacing on the metal plate as needed, saving labor costs, ensuring high work continuity, and providing convenience for punching operations.

Detailed Implementation

[0028] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0029] Example 1:

[0030] Reference Figures 1 to 5 The present invention provides a high-continuity metal sheet processing apparatus, comprising:

[0031] The frame 1 has a winding roller 11 for winding metal sheets that is rotatably mounted on the frame 1, and a slide block 12 that is movable on the frame 1.

[0032] A transmission rod 13 is movably mounted on the frame 1. A transmission mechanism 2 is provided on the frame 1. The transmission rod 13 is connected to the slide 12 through the transmission mechanism 2. The transmission rod 13 can move relative to the frame 1, thereby driving the slide 12 to move.

[0033] A drive cylinder 3 is mounted on a frame 1. The piston rod of the drive cylinder 3 is provided with a mounting bracket 31 and a punching assembly 4 for punching holes in a metal plate. A pusher 32 for pushing the transmission rod 13 is movably mounted on the mounting bracket 31. An adjustment mechanism 5 for adjusting the distance between the pusher 32 and the mounting bracket 31 is provided on the mounting bracket 31.

[0034] The elastic mechanism 6 is mounted on the frame 1 and can act on the transmission rod 13 to drive the transmission rod 13 to extend relative to the frame 1.

[0035] Limiting roller group 7 is provided on both the frame 1 and the slide 12. The limiting roller group 7 includes a pair of rotating rollers 71. The frame 1 and the slide 12 are rotatably mounted with a pair of rotating rollers 71. The two rotating rollers 71 are located on the upper and lower sides of the metal plate and are in close contact with the metal plate. The frame 1 and the slide 12 are provided with a ratchet mechanism 8. The ratchet mechanism 8 can act on the rotating rollers 71 so that the rotating rollers 71 can only rotate in one direction, so that the metal plate can only be conveyed in one direction along the frame 1.

[0036] During operation, the drive cylinder 3 drives the mounting frame 31, the push frame 32, and the punching assembly 4 to descend. The punching assembly 4 punches holes in the metal plate on the frame 1. As the push frame 32 descends, it pushes the transmission rod 13. The transmission rod 13, through the transmission mechanism 2, drives the slide 12 to the left, away from the punching assembly 4. As the slide 12 moves to the left, the limiting roller group 7 on the frame 1, in conjunction with the ratchet mechanism 8, provides a one-way fixation for the metal plate, allowing it to move only to the right. At this time, the rotating roller 71 on the slide 12 rotates and moves forward relative to the metal plate. When the drive cylinder 3 drives the push frame 32 to rise, under the action of the elastic mechanism 6, the transmission rod 13 returns to its original position and passes through the transmission mechanism 2. Mechanism 2 drives slide 12 to approach punching assembly 4. During the movement of slide 12 to the right, the roller 71 on slide 12 cannot rotate due to the action of ratchet mechanism 8. Under the action of friction, it drives the metal plate to move to the right, that is, to feed material to punching assembly 4. During the reciprocating drive of drive cylinder 3, continuous feeding and continuous punching can be achieved. Furthermore, the height position of push frame 32 relative to transmission rod 13 can be adjusted by adjusting distance mechanism 5, thereby adjusting the length of material conveyed by slide 12 in a single operation. This allows workers to adjust the hole spacing on the metal plate as needed, saving labor costs, ensuring high work continuity, and providing convenience for punching operations.

[0037] Specifically, the limiting roller group 7 also includes a pair of mounting plates 72, on which the rotating rollers 71 are rotatably mounted. The two mounting plates 72 are fastened together by bolts to drive the two rotating rollers 71 to adhere tightly to the metal plate from the upper and lower sides.

[0038] Specifically, the ratchet 81 assembly consists of a ratchet 81, a pawl 82, and a torsion spring 83. The ratchet 81 is coaxially arranged with the rotating roller 71 and can rotate synchronously. The pawl 82 is rotatably mounted on the mounting plate 72. The torsion spring 83 can act on the pawl 82 to drive the pawl 82 to elastically abut against the ratchet 81. The pawl 82 can cooperate with the ratchet 81 so that the rotating roller 71 can only rotate in one direction.

[0039] Example 2:

[0040] Reference Figures 1 to 5 In conjunction with the technical solution of Embodiment 1, in this embodiment, the transmission mechanism 2 includes a vertical rack 21, a first gear 22, a second gear 23, and a horizontal rack 24. The vertical rack 21 is connected to the transmission rod 13. The first gear 22 is provided with a transmission shaft for coaxial connection with the second gear 23. The transmission shaft is rotatably mounted on the frame 1. The first gear 22 meshes with the vertical rack 21, the second gear 23 meshes with the horizontal rack 24, and the horizontal rack 24 is connected to the slide 12 and can drive the slide 12 to move.

[0041] During the process of the transmission rod 13 driving the vertical rack 21 to move, the vertical rack 21 drives the second gear 23 to rotate through the first gear 22, and the second gear 23 drives the horizontal rack 24 to move, thus realizing the transmission connection between the transmission rod 13 and the slide 12, so that the transmission rod 13 can drive the slide 12 to move back and forth.

[0042] Specifically, the elastic mechanism 6 includes a mounting cylinder 61, a return spring 62, and a moving rod 63. The mounting cylinder 61 is mounted on the frame 1, and the moving rod 63 is movably mounted on the mounting cylinder 61. The moving rod 63 is connected to the transmission rod 13. The return spring 62 is installed in the inner cavity of the mounting cylinder 61. The return spring 62 can push against the moving rod 63 to drive the transmission rod 13 to extend relative to the frame 1.

[0043] During the process of the drive cylinder 3 driving the push frame 32 to move downward, the transmission rod 13 drives the moving rod 63 to move downward, and the return spring 62 is in a compressed state. During the process of the drive cylinder 3 driving the push frame 32 to move upward, the push frame 32 moves away from the transmission rod 13, and the return spring 62 pushes the moving rod 63 to move upward and reset through the moving rod 63, so as to realize the reciprocating movement of the transmission rod 13 in the vertical direction.

[0044] Example 3:

[0045] Reference Figures 1 to 5In conjunction with the technical solutions of Embodiments 1 and 2, in this embodiment, the punching assembly 4 includes a mounting base 41, a pressure plate 42, an elastic element 43, and a punch 44. The mounting base 41 is movably mounted on the frame 1 and connected to the piston rod of the drive cylinder 3. The punch 44 is disposed on the mounting base 41. The pressure plate 42 is movably mounted on the mounting base 41. The pressure plate 42 is provided with a through hole for the punch 44 to pass through. The elastic element 43 can act on the pressure plate 42 to drive the pressure plate 42 to extend relative to the mounting base 41.

[0046] Specifically, the pressure plate 42 is provided with a mounting post 421, the mounting base 41 is provided with a mounting hole for the mounting post 421 to be moved and installed, the mounting post 421 is provided with an abutment plate 422 that can abut against the mounting base 41, the elastic element 43 is a compression spring, the compression spring is sleeved on the mounting post 421, and the compression spring can push the pressure plate 42 so that the abutment plate 422 abuts against the mounting base 41.

[0047] Specifically, the mounting base 41 is equipped with a cutter 411 for cutting metal plates.

[0048] Working principle:

[0049] During the process of driving the mounting base 41 to descend by the drive cylinder 3, the pressure plate 42 first elastically presses against the metal plate under the action of the compression spring. The punch 44 on the mounting base 41 descends with the mounting base 41 and passes through the hole on the pressure plate 42 to punch the metal plate on the frame 1. At the same time, the cutter 411 on the mounting base 41 cuts off the metal plate that has been punched, thus realizing the continuous punching and unloading of the workpiece.

[0050] Specifically, the adjusting mechanism 5 includes a drive motor 51 and a screw 52. The drive motor 51 is mounted on the mounting bracket 31. The drive motor 51 is connected to the screw 52 and can drive the screw 52 to rotate. The push bracket 32 ​​is provided with a screw hole that mates with the screw 52.

[0051] The screw 52 is driven to rotate by the drive motor 51. During the rotation of the screw 52, ​​it cooperates with the screw hole on the push frame 32 to drive the push frame 32 to move relative to the mounting frame 31. This realizes the adjustment of the height position of the push frame 32 relative to the transmission rod 13, thereby adjusting the length of material conveyed by the slide 12 in a single operation. This allows the staff to adjust the hole spacing on the metal plate as needed.

[0052] Specifically, a rubber sleeve is fitted around the outer periphery of the roller 71. The rubber sleeve is fitted around the outer periphery of the roller 71 to increase the friction between the roller 71 and the metal plate, which is beneficial to the normal operation of the limit roller group 7 in conveying the metal plate.

[0053] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of the present invention without departing from the scope of the present invention are within the protection scope of the present invention.
