Description

Technical Field

[0001] This utility model relates to the field of punching machine technology, and in particular to an automatic punching machine with automatic feeding function. Background Technology

[0002] During the processing of metal sheets, punching operations are often required. Punching requires the use of a punching machine. A punching machine is a mechanical device in which the raw material is installed, and under the drive of a power mechanism, the punching die acts on the material to complete the punching.

[0003] Existing punching machines require manual placement of the metal plate into the punching position for fixation before the machine is started to punch the plate. Finally, the punched plate is removed, which is cumbersome, reduces work efficiency, and increases the labor intensity of workers. Utility Model Content

[0004] In view of this, the present invention provides an automatic punching machine with automatic feeding function. The main technical problem to be solved is that it solves the problem of low work efficiency and high labor intensity caused by manual handling of metal plates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic punching machine with automatic feeding function, comprising a frame, a feeding device fixedly connected to the left side of the top of the frame, a material box fixedly connected to the middle of the top of the frame, limit devices fixedly connected to both the front and rear sides of the right side of the top of the frame, a collecting device placed on the right side of the lower part of the frame, a punching device fixedly connected to the right side of the top of the frame, the feeding device comprising a fixed column fixedly connected to the left side of the top of the frame, a second hydraulic telescopic rod fixedly connected inside the fixed column, and a push plate fixedly connected to the right side of the second hydraulic telescopic rod.

[0006] By adopting the above technical solution, the second hydraulic telescopic rod is activated to drive the pusher plate to push the material plate in the hopper. When the second hydraulic telescopic rod extends to its maximum length, the material plate is in the punching position. Then, the punching device is activated to punch the material plate. After punching is completed, the second hydraulic telescopic rod returns to its original position. Under the action of gravity, the stacked material plates in the hopper can move downward, so that the bottom material plate can contact the bottom of the hopper. Then, the second hydraulic telescopic rod is controlled to push the material plate out for punching again. This process is repeated to automatically convey and punch the material plates. The punched material plates are pushed by the subsequently punched material plates. Through continuous pushing, the material plates can slide into the collection device, which facilitates the automatic collection of the punched material plates.

[0007] As a further description of the above technical solution: the frame includes a placement plate, a support column is fixedly connected to the lower part of the placement plate, a through hole is provided inside the placement plate, and a feeding tray is fixedly connected to the right side of the placement plate.

[0008] By adopting the above technical solution, the through hole is used for the punch head to pass through during stamping, and a feeding tray is fixedly connected to the right side of the placement plate. The feeding tray is used to guide the conveying of the stamped plate.

[0009] As a further description of the above technical solution: the collecting device includes a collecting box placed on the lower right side of the feeding tray, a pusher fixedly connected to the top right side of the collecting box, a fixing block fixedly connected to the lower part of the collecting box, a rotating shaft movably connected inside the fixing block, and rollers fixedly connected to both ends of the rotating shaft.

[0010] By adopting the above technical solution, the collection box is used to collect the stamped material plates. The rotating shaft can rotate inside the fixed block, thereby enabling the rollers to rotate and the collection device to move, facilitating the transportation of the collected material plates.

[0011] As a further description of the above technical solution: the limiting device includes a fixed cylinder fixedly connected to the front and rear sides of the right side of the top of the placement plate, a compression plate is movably connected inside the fixed cylinder, a compression spring is fixedly connected between the fixed cylinder and the compression plate, and a limiting post is fixedly connected to the top of the fixed cylinder.

[0012] By adopting the above technical solution, the distance between the lower part of the inner side of the limiting post and the placement plate is adapted to the thickness of the material plate to prevent the material plate from moving up and down. The inner side of the extrusion plate near the material box is set with an arc. When the push plate pushes the material plate to move between the limiting devices, the material plate can squeeze the extrusion plate, so that the extrusion plate can retract into the fixed cylinder, and then the extrusion plate can squeeze the extrusion spring, which in turn can generate a reverse force, so that the extrusion plate can squeeze the material plate, making the resistance when the material plate moves greater, preventing the material plate from deviating from the punching position due to inertia, and ensuring higher punching accuracy.

[0013] As a further description of the above technical solution: the punching device includes a support rod fixedly connected to the top right side of the placement plate, a top plate fixedly connected to the top of the support rod, a first hydraulic telescopic rod fixedly connected inside the top plate, a connecting plate fixedly connected to the lower part of the first hydraulic telescopic rod, a sliding column movably connected inside the connecting plate, a fixing sleeve fixedly connected to the lower end of the sliding column, an anti-slip sleeve fixedly connected to the lower part of the fixing sleeve, a tightening spring fixedly connected between the connecting plate and the fixing sleeve, and a punching head fixedly connected to the middle of the lower part of the connecting plate.

[0014] By adopting the above technical solution, the first hydraulic telescopic rod is activated, which drives the connecting plate to move downward. Through continuous movement, the anti-slip sleeve first contacts the material plate, and through continuous descent, the fixed sleeve drives the sliding column to move upward relative to the connecting plate. This allows the fixed sleeve to compress the top spring, causing the top spring to generate a reverse force. This allows the anti-slip sleeve to firmly press the material plate, making the material plate more secure. Furthermore, through continuous descent, the punching head contacts the material plate, and through compression, the punching of the material plate is completed.

[0015] As a further description of the above technical solution: the material box includes a box body fixedly connected to the middle of the top of the placement plate, and the material plate is placed inside the box body.

[0016] By adopting the above technical solution, the thickness and width of the material plate are the same as those of the push plate. The lower left and right sides of the box are provided with slots for the material plate and the push plate to pass through, ensuring that the push plate can push the material plate out.

[0017] By employing the above technical solution, the automatic punching machine with automatic feeding function of this utility model has at least the following beneficial effects:

[0018] Compared with existing technologies, this automatic punching machine with automatic feeding function, through the inclusion of a limiting device, a material box, and a feeding device, facilitates the automatic conveying and collection of material plates. In use, multiple material plates are stacked in the box. Activating the second hydraulic telescopic rod causes it to drive a pusher plate to push the material plates in the material box. When the second hydraulic telescopic rod extends to its maximum length, the material plate is in the punching position. After the material plate is pushed out, it contacts the extrusion plate. Through continuous movement, the material plate can compress the extrusion plate, causing the extrusion plate to retract into the fixed cylinder. This allows the extrusion plate to compress the extrusion spring, which in turn generates a counterforce, further compressing the material plate. This increases the resistance during material plate movement, preventing the material plate from... The material plate deviates from the punching position due to inertia, ensuring higher punching accuracy. The limiting post prevents the material plate from moving up and down. The punching device is then activated to punch the material plate. After punching, the second hydraulic telescopic rod returns to its original position. Under gravity, the stacked material plates in the box move downwards, allowing the bottommost plate to contact the bottom of the box. The second hydraulic telescopic rod is then controlled again to push the material plate out for punching. This process is repeated to automatically convey and punch the material plates. The punched material plates are pushed by subsequently punched material plates, continuously pushing them into the collection device for automatic collection. This eliminates the need for manual handling, increasing work efficiency and reducing labor costs. Attached Figure Description

[0025] Reference Figure 1-5This utility model provides an automatic punching machine with automatic feeding function, including a frame 1. A feeding device 6 is fixedly connected to the left side of the top of the frame 1, a material box 5 is fixedly connected to the middle of the top of the frame 1, limit devices 3 are fixedly connected to the front and rear sides of the right side of the top of the frame 1, a collecting device 2 is placed on the right side of the lower part of the frame 1, and a punching device 4 is fixedly connected to the right side of the top of the frame 1. The feeding device 6 includes a fixed column 602 fixedly connected to the left side of the top of the frame 1, a second hydraulic telescopic rod 601 fixedly connected inside the fixed column 602, and a push plate 603 fixedly connected to the right side of the second hydraulic telescopic rod 601. By activating the second hydraulic telescopic rod 601, it can drive the push plate 603 to push the material plate 502 in the material box 5. After the telescopic rod 601 extends to its maximum length, the material plate 502 is in the punching position. Then, the punching device 4 is activated to punch the material plate 502. After punching is completed, the second hydraulic telescopic rod 601 returns to its original position. Under the action of gravity, the material plates 502 stacked in the box 501 can move downward, so that the bottom material plate 502 can contact the bottom of the box 501. Then, the second hydraulic telescopic rod 601 is controlled to push out the material plate 502 for punching. This process is repeated to automatically convey and punch the material plate 502. The punched material plate 502 is pushed by the subsequently punched material plate 502. Through continuous pushing, the material plate 502 can slide into the collecting device 2, which facilitates the automatic collection of the punched material plate 502.

[0026] Furthermore, the frame 1 includes a placement plate 101, with a support column 102 fixedly connected to the lower part of the placement plate 101. The placement plate 101 has a through hole 103 inside, which is used for the punch head 406 to pass through during stamping. A feeding tray 104 is fixedly connected to the right side of the placement plate 101, which is used to guide the conveying of the stamped material plate 502.

[0027] Furthermore, the collecting device 2 includes a collecting box 201 placed on the lower right side of the unloading tray 104. The collecting box 201 is used to collect the stamped material plate 502. A pusher 202 is fixedly connected to the top right side of the collecting box 201. A fixing block 203 is fixedly connected to the lower part of the collecting box 201. A rotating shaft 204 is movably connected inside the fixing block 203. Rollers 205 are fixedly connected to both ends of the rotating shaft 204. The rotating shaft 204 can rotate inside the fixing block 203, thereby enabling the rollers 205 to rotate, allowing the collecting device 2 to move and facilitating the transport of the collected material plate 502.

[0028] Furthermore, the limiting device 3 includes fixed cylinders 301 fixedly connected to the front and rear sides of the top right side of the placement plate 101. The distance between the fixed cylinders 301 is adapted to the width of the material plate 502 to prevent the material plate 502 from moving back and forth. A pressing plate 303 is movably connected inside the fixed cylinders 301 and can move inside the fixed cylinders 301. A compression spring 302 is fixedly connected between the fixed cylinders 301 and the pressing plate 303. A limiting post 304 is fixedly connected to the top of the fixed cylinders 301. The distance between the lower part of the inner side of the limiting post 304 and the placement plate 101 is adapted to the thickness of the material plate 502 to prevent the material plate 502 from moving back and forth. The plate 502 moves up and down. The inner side of the extrusion plate 303, near the material box 5, is set with an arc. When the push plate 603 pushes the material plate 502 to move between the limiting device 3, the material plate 502 can squeeze the extrusion plate 303, so that the extrusion plate 303 can retract into the fixed cylinder 301. In turn, the extrusion plate 303 can squeeze the extrusion spring 302, so that the extrusion spring 302 can generate a reverse force, so that the extrusion plate 303 can squeeze the material plate 502. This makes the resistance of the material plate 502 when it moves greater, preventing the material plate 502 from deviating from the punching position due to inertia and ensuring higher punching accuracy.

[0029] Furthermore, the punching device 4 includes a support rod 403 fixedly connected to the top right side of the placement plate 101. A top plate 401 is fixedly connected to the top of the support rod 403. A first hydraulic telescopic rod 402 is fixedly connected inside the top plate 401. A connecting plate 405 is fixedly connected to the lower part of the first hydraulic telescopic rod 402. A sliding column 404 is movably connected inside the connecting plate 405, allowing it to move within the connecting plate 405. A fixing sleeve 407 is fixedly connected to the lower end of the sliding column 404. An anti-slip sleeve 408 is fixedly connected to the lower part of the fixing sleeve 407. The anti-slip sleeve 408 is made of rubber and has a certain anti-slip function. A tightening spring 409 is fixedly connected between the connecting plate 405 and the fixing sleeve 407. A punch head 406 is fixedly connected to the middle of the lower part of 05. By activating the first hydraulic telescopic rod 402, it can drive the connecting plate 405 to move downward. Through continuous movement, the anti-slip sleeve 408 can first contact the material plate 502. Through continuous descent, the fixed sleeve 407 can drive the sliding column 404 to move upward relative to the connecting plate 405. This allows the fixed sleeve 407 to compress the top spring 409, causing the top spring 409 to generate a reverse force. This allows the anti-slip sleeve 408 to firmly press the material plate 502, making the material plate 502 more secure. Through continuous descent, the punch head 406 can contact the material plate 502, and through compression, the punching of the material plate 502 is completed.

[0030] Furthermore, the material box 5 includes a box body 501 fixedly connected to the top center of the placement plate 101. The inside of the box body 501 is a material plate 502. The thickness and width of the material plate 502 are the same as those of the push plate 603. The lower left and right sides of the box body 501 are provided with slots for the material plate 502 and the push plate 603 to pass through, so as to ensure that the push plate 603 can push out the material plate 502.

[0031] Working principle: Multiple material plates 502 are stacked in the housing 501. Activating the second hydraulic telescopic rod 601 drives the pusher plate 603 to push the material plates 502 in the housing 5. When the second hydraulic telescopic rod 601 extends to its maximum length, the material plate 502 is in the punched position. After the material plate 502 is pushed out, it contacts the extrusion plate 303. Through continuous movement, the material plate 502 can compress the extrusion plate 303, causing the extrusion plate 303 to retract into the fixed cylinder 301. This allows the extrusion plate 303 to compress the compression spring 302, which in turn generates a counterforce, enabling the extrusion plate 303 to compress the material plate 502. This increases the resistance to movement of the material plate 502, preventing it from deviating due to inertia. The punching position ensures higher punching accuracy, and the limiting post 304 prevents the material plate 502 from moving up and down. Then, the punching device 4 is activated to punch the material plate 502. After punching is completed, the second hydraulic telescopic rod 601 returns to its original position. Under the action of gravity, the stacked material plates 502 in the box 501 can move downward, so that the bottom material plate 502 can contact the bottom of the box 501. Then, the second hydraulic telescopic rod 601 is controlled to push the material plate 502 out for punching again. This process is repeated to automatically convey and punch the material plate 502. The punched material plate 502 is pushed by the subsequently punched material plate 502. Through continuous pushing, the material plate 502 can slide into the collecting device 2, which facilitates the automatic collection of the punched material plate 502.
