Description

Technical Field

[0001] This utility model relates to the field of punching and cutting device technology, specifically to a punching and cutting device that is easy to maintain. Background Technology

[0002] Circuit boards are essential in electrical equipment. With the continuous advancement of technology, the size of circuit boards is getting smaller and smaller, moving towards miniaturization. The processing of miniature circuit boards generally involves dividing a large board into many miniature circuit boards, which requires the use of punching and cutting equipment.

[0003] Existing punching devices require operators to replace or maintain the blades periodically after prolonged use. However, since the blades are fixedly installed to the stamping plate, tools are needed to completely disassemble the stamping plate before the blades can be replaced or maintained. This prolonged disassembly can easily cause wear on the stamping plate, leading to unstable connections between the blades and the stamping plate, resulting in poor practicality. Therefore, we propose an easy-to-maintain punching device to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide an easy-to-maintain punching device to solve the problem mentioned in the background art that the existing punching devices require operators to replace or maintain the blades from time to time after long-term use. However, since the blades and the stamping plate are fixedly installed, when it is necessary to replace or maintain the blades, tools must be used to completely disassemble the stamping plate before the blades can be replaced or maintained. This long-term disassembly can easily cause wear on the stamping plate, resulting in unstable connection between the blades and the stamping plate, and poor practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-maintain punching device, comprising a worktable, support plates mounted on both sides of the top of the worktable, a top plate mounted on the top of the support plates, a cylinder mounted on the top of the top plate, a stamping plate mounted on the output shaft at the bottom of the cylinder, a slot provided at the bottom of the stamping plate, a cutter engaged inside the slot, first transverse grooves provided on both sides inside the stamping plate, the first transverse grooves communicating with the slots, a limit spring installed inside the first transverse grooves, a limit block installed at the other end of the limit spring, the bottom of the limit block being an inclined surface, a first telescopic rod installed inside the limit spring, limit grooves provided on both sides of the cutter, and the limit block located inside the limit grooves.

[0006] Preferably, the top of the stamping plate is provided with a second transverse groove on both sides, the second transverse groove is connected to the first transverse groove, a second slide rod is installed inside the second transverse groove, a slide plate is slidably connected to the outer wall of the second slide rod, the bottom of the slide plate is fixedly connected to the limiting block, and the top of the slide plate is located outside the second transverse groove.

[0007] Preferably, the front end of the stamping plate is provided with a positioning groove, the positioning groove passes through the slot, the cross-sectional shape of the positioning groove is set to be circular, and the interior of the positioning groove is provided with an internal thread groove. A positioning rod is threadedly connected to the interior of the positioning groove, a knob is installed at the front end of the positioning rod, and a round hole is provided at the corresponding position on the upper part of the cutter.

[0008] Preferably, a fixing sleeve is installed on one side of the opposite sides of the two support plates. The fixing sleeve is rotatably connected to the support plate. A threaded rod is threaded inside the fixing sleeve. A clamping plate is installed through the support plate on one side of the threaded rod. A vertical groove is provided on one side of the opposite faces of the two clamping plates.

[0009] Preferably, a drive motor is installed on one side of the opposite sides of the two support plates, a first gear is installed on the output shaft of the drive motor, and a second gear is installed on the outer wall of the fixed sleeve, with the first gear and the second gear meshing together.

[0010] Preferably, a second telescopic rod is installed on one side of the lower part of the two clamping plates opposite to each other, and the other side of the second telescopic rod is fixedly connected to the support plate.

[0011] Preferably, a first slide rod is installed around the top of the workbench, the top of the first slide rod is fixedly connected to the top plate, the first slide rod passes through the stamping plate and is slidably connected to the stamping plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) The present invention can achieve automatic locking setting of the cutter by the inclined surface design of the limiting block, without the need for additional tools. The continuous elastic force of the limiting spring can ensure that the limiting block does not fall off during punching. By the cooperation of the sliding plate and the second sliding rod, the cutter can be unlocked by pushing the sliding plate. This solves the problem that the existing punching device requires the staff to replace or maintain the blade from time to time after long-term use. However, since the blade and the stamping plate are fixedly installed, when the blade needs to be replaced or maintained, the stamping plate needs to be completely disassembled with tools before the blade can be replaced or maintained. This long-term disassembly can easily cause wear on the stamping plate, resulting in unstable connection between the blade and the stamping plate, which is not very practical.

[0013] (2) By screwing the positioning rod into the round hole of the cutter through the thread, the longitudinal and lateral displacement of the cutter can be further restricted during high-frequency punching. This allows for convenient disassembly and assembly of the cutter and effectively improves the connection stability between the punching plate and the cutter.

[0014] (3) The first gear and the second gear are driven by the drive motor to rotate, so that the fixed sleeve rotates synchronously. The fixed sleeve and the threaded rod can push the clamping plate to move to both sides of the cutter. At this time, the cutter is stably supported by the clamping plate, which can replace the hand to lift it and avoid the cutter from falling or shaking, which would make disassembly difficult.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-4This utility model provides an embodiment of an easy-to-maintain punching device, comprising a workbench 1, support plates 2 mounted on both sides of the top of the workbench 1, a top plate 3 mounted on the top of the support plates 2, a cylinder 4 mounted on the top of the top plate 3, a stamping plate 5 mounted on the output shaft at the bottom of the cylinder 4, a slot 6 provided at the bottom of the stamping plate 5, a cutter 7 being engaged inside the slot 6, first transverse grooves 8 provided on both sides inside the stamping plate 5, the first transverse grooves 8 communicating with the slot 6, a limit spring 9 installed inside the first transverse groove 8, a limit block 10 installed at the other end of the limit spring 9, the bottom of the limit block 10 being sloped, a first telescopic rod 11 installed inside the limit spring 9, limit grooves 12 provided on both sides of the cutter 7, and the limit block 10 located inside the limit groove 12. Please refer to [link to relevant documentation]. Figure 2 The top of the stamping plate 5 has two second transverse grooves 13 on both sides, which are connected to the first transverse groove 8. A second slide rod 14 is installed inside the second transverse groove 13, and a slide plate 15 is slidably connected to the outer wall of the second slide rod 14. The bottom of the slide plate 15 is fixedly connected to the limiting block 10, and the top of the slide plate 15 is located outside the second transverse groove 13. (See also...) Figure 4 The front end of the stamping plate 5 has a positioning groove 16, which penetrates the slot 6. The positioning groove 16 has a circular cross-section and an internal thread. A positioning rod 17 is threaded into the internal part of the positioning groove 16, and a knob 18 is installed at the front end of the positioning rod 17. A circular hole 19 is provided at a corresponding position on the upper part of the cutter 7. Please refer to [link / reference]. Figure 2 A fixing sleeve 20 is installed on one side of the opposite side of the two support plates 2. The fixing sleeve 20 is rotatably connected to the support plate 2. A threaded rod 21 is threaded inside the fixing sleeve 20. A clamping plate 22 is installed through the support plate 2 on one side of the threaded rod 21. A vertical groove 23 is provided on one side of the opposite face of the two clamping plates 22. Please refer to Figure 3A drive motor 24 is mounted on one side of the back of the two support plates 2. A first gear 25 is mounted on the output shaft of the drive motor 24, and a second gear 26 is mounted on the outer wall of the fixed sleeve 20. The first gear 25 and the second gear 26 are meshed together. When the device is in use, the cylinder 4 drives the stamping plate 5 to move down along the first slide rod 28, and the cutter 7 completes the punching. At this time, the clamping plate 22 is in a retracted state under the control of the drive motor 24 to avoid interfering with the punching action of the cutter 7. When it is necessary to maintain the cutter 7, first adjust the stamping plate 5 to a semi-suspended state using the cylinder 4, so that the lower end of the cutter 7 is detached from the worktable 1 for easy operation. Start the drive motor 24, which drives the first gear 25 to rotate. Through the meshing connection, the second gear 26 is driven to rotate synchronously, thereby causing the fixed sleeve 20 to rotate. Through the threaded engagement between the fixed sleeve 20 and the threaded rod 21, the clamping plate 22 can be pushed to move to both sides of the cutter 7 until the vertical grooves 23 on both sides firmly clamp the cutter 7. At this time, the cutter 7 is stably supported by the clamping plate 22, replacing the manual lifting. Rotating the knob 18 rotates the positioning rod 17 and pulls it out, releasing the secondary fixation. Pushing the slide plate 15 to both sides causes the slide plate 15 to slide along the second slide rod 14, which in turn causes the limit block 10 to compress the limit spring 9 and exit the limit groove 12 of the cutter 7, releasing the initial fixation. Since the cutter 7 is firmly clamped by the clamping plate 22, there is no need to lift it by hand. The cylinder 4 drives the stamping plate 5 to rise, which can pull the cutter 7 out of the slot 6. The clamping plate 22 provides stable support for the cutter 7, preventing the cutter 7 from falling or shaking, which would make disassembly difficult. When it is necessary to install the new cutter 7, align the new cutter 7 with the slot 6 and insert it. The inclined surface at the bottom of the limiting block 10 allows the new cutter 7 to enter the slot 6 while compressing the limiting spring 9. When the top of the new cutter 7 contacts the inner top of the slot 6, the elastic force of the limiting spring 9 causes the limiting block 10 to engage with the limiting groove 12, which can initially fix the new cutter 7. Then, screw in the positioning rod 17 to fix the new cutter 7 a second time. The installation of the cutter 7 is then complete.

[0018] Please see Figure 2 A second telescopic rod 27 is installed on one side of the lower part of the two clamping plates 22 facing each other, and the other side of the second telescopic rod 27 is fixedly connected to the support plate 2. The second telescopic rod 27 can provide a limiting function for the clamping plates 22, preventing the clamping plates 22 from rotating when moving, ensuring the smooth movement of the clamping plates 22 and avoiding clamping off-center.

[0019] Please see Figure 2 and Figure 4 The top of the workbench 1 is equipped with a first slide rod 28 around its perimeter. The top of the first slide rod 28 is fixedly connected to the top plate 3. The first slide rod 28 passes through the stamping plate 5 and is slidably connected to the stamping plate 5. The first slide rod 28 allows the stamping plate 5 to move up and down along it, thereby ensuring the vertical movement of the stamping plate 5 and guaranteeing the cutting accuracy of the cutter 7.
