Description

Technical Field

[0001] This utility model relates to the field of punching machine technology, specifically a copper busbar punching machine. Background Technology

[0002] A punching machine is a mechanical device that, after the raw material is installed, uses a power mechanism to drive a punching die to punch a hole in the material. Punching machines can perform operations such as sheet metal processing, stamping, die pressing, and embossing, forcing metal into the die.

[0003] When punching copper plates, existing punching machines require tools to hold the copper plate in place for processing. During this process, even slight vibrations from the operator can cause the punching position to shift, resulting in losses. Secondly, using clamping tools to hold the copper plate in place is a cumbersome process that significantly reduces work efficiency. Furthermore, the processing position being too close to the operator can easily pose a safety risk. Utility Model Content

[0004] The purpose of this utility model is to provide a copper busbar punching machine, which solves the problems of the following: when punching copper plates, the copper plate needs to be held in place by a tool for processing. During the process, even slight shaking of the operator may cause the punching position to shift, resulting in losses. Secondly, when using a clamping tool to hold the copper plate in place, the operation steps are cumbersome, which seriously reduces the work efficiency. Furthermore, the processing position is too close to the operator, which may cause safety risks.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a copper busbar punching machine, comprising: a base and a punching head, wherein a mounting bracket for mounting the punching head is fixedly connected to the top of the base, and the output end of the punching head passes through the mounting bracket and extends to its inner side; two symmetrical support bars are fixedly connected to the top of the base, and a sliding groove for connection is opened on the top of the support bars, the sliding groove having a U-shaped cross section;

[0006] The support bar has a mounting block for support at one end near the mounting frame, and the mounting block is fixedly connected to the surface of the base. A pushing mechanism is movably connected to the rear side of the mounting block, and the front end of the pushing mechanism is movably connected to the inside of the slide groove. A placement plate is fixedly connected to the top of the pushing mechanism. The placement plate has scale lines engraved at one end near the mounting frame, and a groove is opened in the middle of the front side of the placement plate. A limiting mechanism for fixing the copper sheet is movably connected inside the groove.

[0007] Furthermore, the limiting mechanism includes a connecting shaft, a control bar, and a pressure bar. Two control bars are provided and are fixedly connected to the outside of the connecting shaft in a symmetrical manner. The pressure bar is fixedly connected to one end of the control bar, and the control bar is arc-shaped. The two ends of the connecting shaft are respectively rotatably connected to the two ends of the inside of the groove by torque springs, and the two ends of the inside of the groove are provided with limiting holes.

[0008] Furthermore, the limiting mechanism also includes an electric telescopic rod, a drive bar, a push rod, a fixing ring, and a return spring. The drive bar has two sections and is movably connected to the telescopic end of the electric telescopic rod via a rotating shaft. The push rods are movably connected to the other end of the drive bar via rotating shafts, and the fixing rings are fixedly connected to the middle position of the push rods. The return springs are respectively sleeved on the end of the push rod away from the electric telescopic rod.

[0009] Furthermore, the end of the electric telescopic rod away from the drive bar is fixedly connected to the middle position of the connecting shaft, and the end of the control bar away from the pressure bar is provided with connecting holes, and the end of the push rod away from the drive bar is movably connected to the inside of the connecting hole, and the push rod is adapted to the limiting hole.

[0010] Furthermore, the pushing mechanism includes a drive motor, a main sprocket, a transmission sprocket, a chain, and a support frame. The drive motor is fixedly connected to the top of the support frame, and the bottom of the support frame is fixedly connected to one end of the base. The main sprocket is fixedly connected to the output end of the drive motor through a coupling. There are two transmission sprockets, which are symmetrically arranged with the main sprocket as the axis of symmetry. The main sprocket and the two transmission sprockets are connected by chain drive.

[0011] Furthermore, the pushing mechanism also includes a threaded rod and a slider. One end of the threaded rod is movably connected to one end of the slide groove via a bearing, and the other end of the threaded rod passes through the slide groove and the mounting block in sequence and is fixedly connected to the shaft center of the transmission sprocket. The connection between the threaded rod and the mounting block is movably connected via a bearing. The slider is movably connected to the surface of the threaded rod via a thread. The top end of the slider extends out of the slide groove and is fixedly connected to the bottom end of the placement plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a limiting mechanism to apply pressure to one end of the control bar by pressing down on the copper plate. At this time, the bottom end of the control bar moves downward, which in turn drives the connecting shaft to rotate. Simultaneously, the top of the control bar flips downward and pushes the pressure plate down until the bottom of the copper plate contacts the surface of the placement plate. At this time, the pressure plate is close to the surface of the copper plate. Then, the electric telescopic rod is controlled to push the drive bar with its top end. At this time, the other end of the drive bar moves exaggeratedly to both sides, causing its push rod to pass through the connecting hole and insert into the interior of the limiting hole. At the same time, the return spring is squeezed and contracted by the fixing ring, which helps to fix the copper plate to be punched, avoids displacement of the copper plate during processing, and prevents the punching position from shifting. It also makes it easier to fix and remove the copper plate.

[0014] 2. This utility model uses a push mechanism to synchronously drive two transmission sprockets along the same trajectory via a servo motor through a main sprocket and a chain. At this time, the threaded rod is driven to rotate by the transmission sprocket, and the slider is driven by the thread to move the placement plate towards the bottom of the punching head. This facilitates automated operation of the equipment, ensures that the processing end is far away from the workers, and reduces production safety risks. Attached Figure Description

[0024] Please see Figures 1 to 6 The present invention preferably provides the following technical solution: a copper busbar punching machine, comprising: a base 1 and a punching head 2, wherein a mounting bracket 3 for mounting the punching head 2 is fixedly connected to the top of the base 1, and the output end of the punching head 2 passes through the mounting bracket 3 and extends to its inner side; two symmetrical support strips 4 are fixedly connected to the top of the base 1, and a sliding groove 5 for connection is opened on the top of the support strips 4, the sliding groove 5 having a concave cross-section;

[0025] A mounting block 6 for support is provided at one end of the support bar near the mounting frame 3, and the mounting block 6 is fixedly connected to the surface of the base 1. A pushing mechanism 7 is movably connected to the rear side of the mounting block 6, and the front end of the pushing mechanism 7 is movably connected to the inside of the slide groove 5. A placement plate 8 is fixedly connected to the top of the pushing mechanism 7. The placement plate 8 has scale lines engraved at one end near the mounting frame 3 to facilitate adjustment of the longitudinal drilling position of the steel plate. If the punching position is offset, a groove 9 is opened at the middle of the front side of the placement plate 8. A limiting mechanism 10 for fixing the copper sheet is movably connected inside the groove 9.

[0026] Example 2

[0027] Please see Figures 1 to 6The present invention preferably provides the following technical solution: The limiting mechanism 10 includes a connecting shaft 1001, a control bar 1002, and a pressure bar 1003. Two control bars 1002 are symmetrically fixedly connected to the outside of the connecting shaft 1001. The pressure bar 1003 is fixedly connected to one end of the control bar 1002, and the control bar 1002 is arc-shaped. Both ends of the connecting shaft 1001 are rotatably connected to the inner ends of the groove 9 via torque springs. Limiting holes 11 are provided at both ends of the groove 9. The limiting mechanism 10 also includes an electric telescopic rod 1004, a drive bar 1005, a push rod 1006, a fixing ring 1007, and a return spring 1008. Two drive bars 1005 are provided and... The telescopic end of the electric telescopic rod 1004 is movably connected via a pivot. The push rod 1006 is movably connected to the other end of the drive bar 1005 via a pivot. The fixing ring 1007 is fixedly connected to the middle position of the push rod 1006. The return spring 1008 is sleeved on the end of the push rod 1006 away from the electric telescopic rod 1004. The end of the electric telescopic rod 1004 away from the drive bar 1005 is fixedly connected to the middle position of the connecting shaft 1001. The end of the control bar 1002 away from the pressure bar 1003 is provided with connecting holes 12. The end of the push rod 1006 away from the drive bar 1005 is movably connected to the inside of the connecting hole 12. The push rod 1006 is adapted to the limiting hole 11.

[0028] By pressing the copper plate downwards, pressure is applied to one end of the control bar 1002. The bottom of the control bar 1002 moves downwards, causing the connecting shaft 1001 to rotate. Simultaneously, the top of the control bar 1002 flips downwards and pushes the pressure plate down until the bottom of the copper plate contacts the surface of the placement plate 8. At this point, the pressure plate is close to the surface of the copper plate. Then, the electric telescopic rod 1004 is controlled to push the drive bar 1005 with its top end. The other end of the drive bar 1005 then moves exaggeratedly to both sides, causing its push rod 1006 to penetrate the connecting hole 12 and insert into the limiting hole 11. Simultaneously, the return spring 1008 is compressed and contracted by the fixing ring 1007, and conversely, the control electric telescopic rod 1004 contracts. At this time, the return spring 1008 reacts to the push rod 1006, and then the push rod 1006 slides out from the limiting hole 11. The torque spring reacts to the connecting shaft 1001, causing it to drive the control bar 1002 to reset. At this time, the bottom end of the control bar 1002 pushes the copper plate upward and separates it from the placement plate 8, which facilitates the fixing of the copper plate to be punched, avoids displacement of the copper plate during processing, and prevents the punching position from shifting. It also facilitates the fixing and removal of the copper plate.

[0029] Example 3

[0030] Please see Figures 1 to 3The preferred technical solution provided by this utility model is as follows: The pushing mechanism 7 includes a drive motor 701, a main sprocket 702, a transmission sprocket 703, a chain 704, and a support frame 705. The drive motor 701 is fixedly connected to the top of the support frame 705, and the bottom of the support frame 705 is fixedly connected to one end of the base 1. The main sprocket 702 is fixedly connected to the output end of the drive motor 701 through a coupling. Two transmission sprockets 703 are provided and symmetrically arranged about the main sprocket 702 as an axis of symmetry. The main sprocket 702 and the two transmission sprockets 703 are connected by... The chain 704 is connected for transmission. The pushing mechanism 7 also includes a threaded rod 706 and a slider 707. One end of the threaded rod 706 is movably connected to one end of the slide groove 5 through a bearing, and the other end of the threaded rod 706 passes through the slide groove 5 and the mounting block 6 in sequence and is fixedly connected to the shaft center of the transmission sprocket 703. The connection between the threaded rod 706 and the mounting block 6 is movably connected to the surface of the threaded rod 706 through threads. The top end of the slider 707 extends out of the slide groove 5 and is fixedly connected to the bottom end of the placement plate 8.

[0031] The servo motor drives the two transmission sprockets 703 synchronously and along the same trajectory via the main sprocket 702 and the chain 704. At this time, the threaded rod 706 is driven to rotate by the transmission sprocket 703, and the slider 707 is driven by the thread to move the placement plate 8 towards the bottom of the punch head 2. This facilitates the automated operation of the equipment, ensures that the processing end is far away from the workers, and reduces the risk of production safety issues.

[0032] Based on the above embodiments 1, 2, and 3, the working principle is further described below. In use, a copper plate is placed on the surface of the placement plate 8, and then pressed down forcefully, so that the bottom of the copper plate applies pressure to one end of the control bar 1002. At this time, the bottom end of the control bar 1002 moves downward, thereby driving the connecting shaft 1001 to rotate. Simultaneously, the top of the control bar 1002 flips downward and pushes the pressure plate down until the bottom of the copper plate contacts the surface of the placement plate 8. At this time, the pressure plate is close to the surface of the copper plate. Then, the electric telescopic rod 1004 is controlled so that its top end pushes the drive bar 1005. At this time, the other end of the drive bar 1005 moves exaggeratedly to both sides, causing its push rod 1006 to penetrate the connecting hole 12 and insert into the limiting hole 11. Simultaneously, the return spring 1008 is compressed and contracted by the fixing ring 1007, and conversely, the control electric telescopic rod 1004 contracts. At this time, the return spring 1008 reacts to the push rod 1006, and then the push rod 1006 slides out from the limiting hole 11. The torque spring reacts to the connecting shaft 1001, causing it to drive the control bar 1002 to reset. At this time, the bottom end of the control bar 1002 pushes the copper plate upward and separates it from the placement plate 8. After the copper plate is fixed, the servo motor is started to synchronously drive the two transmission sprockets 703 through the main sprocket 702 and the chain 704. At this time, the threaded rod 706 is driven by the transmission sprocket 703 to rotate, and at the same time, the slider 707 is driven by the thread to move the placement plate 8 towards the bottom of the punching head 2.
