Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically a CNC punching and cutting equipment for producing metal casings for automobile chargers. Background Technology

[0002] Hardware parts used in automobile assembly need to undergo a stamping and forming process, using a cutting blade to punch them into various shapes to meet the processing requirements of automobile assembly production. Currently, mainstream cutting devices typically allow the cutting blade to move only in one direction during operation, which can easily cause the sheet material to shift during the cutting process, resulting in poor cutting accuracy. Although there are devices on the market where both the upper and lower cutting dies can move relative to each other, this design can reduce the impact of the cutting blade on the sheet material. However, such devices require two power mechanisms to drive the upper and lower dies separately, which not only makes it difficult to achieve precise synchronous cutting and affects cutting accuracy, but also has the problems of occupying a large installation space and having high equipment costs.

[0003] Patent CN114131696A proposes a synchronous punching mechanism for upper and lower dies. By synchronously driving the upper and lower dies to move relative to or away from each other through a cam servo power mechanism, it realizes closed die cutting and open die cutting, ensuring consistency of action and reducing the power structure and space occupied.

[0004] However, the aforementioned punching synchronous follow-up mechanism still has the drawback of complex structure, and the upper and lower dies are difficult to move synchronously, requiring the addition of a drive motor, which in turn leads to a corresponding increase in equipment cost. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a CNC punching and cutting equipment for producing metal casings for car chargers, which solves the problems of difficulty in synchronizing the upper and lower dies, complex structure, and the need for an additional power source.

It also includes a punching device comprising an upper template and a lower template, with a punching cutter fixedly connected to the bottom wall of the upper template; and a synchronization component comprising an upper rack, a lower rack, and a gear. The upper and lower racks are slidably connected within the side plates, and the gear is rotatably connected within the side plates, with both sides of the gear meshing with the upper and lower racks respectively.

[0012] (III) Beneficial Effects This utility model provides a CNC punching and cutting machine for producing metal casings for car chargers.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please see Figures 1-5 This utility model provides a technical solution: a CNC punching and cutting equipment for producing metal casings for car chargers, including a base 1, with side plates 11 fixedly connected to both ends of the top of the base 1, and a top plate 12 fixedly connected to both side plates 11. It also includes a punching device 2 and a synchronization component 3. The punching device 2 includes an upper template 21 and a lower template 22, with a punching blade 23 fixedly connected to the bottom wall of the upper template 21. The synchronization component 3 includes an upper rack 31, a lower rack 32, and a gear 33. The upper rack 31 and lower rack 32 are slidably connected within the side plates 11, and the gear 33 is rotatably connected within the side plates 11. Both sides of the gear 33 mesh with the upper rack 31 and the lower rack 32 respectively. The upper rack 31 is fixedly connected to the upper template 21, and the lower rack 32 is fixedly connected to the lower template 22. During operation... First, the raw material for the car charger hardware shell to be processed is placed at the designated station of the lower template 22 to ensure accurate positioning of the raw material. Then, the punching device 2 is started, the upper template 21 is moved down, and the upper rack 31 is driven. The gear 33 rotates as the upper rack 31 moves down. Since the two sides of the gear 33 mesh with the upper rack 31 and the lower rack 32 respectively, the lower rack 32 is driven to slide synchronously in the opposite direction relative to the upper rack 31. The upper rack 31 drives the upper template 21 to move downward, and the lower rack 32 drives the lower template 22 to move upward, so that the punching knife 23 at the bottom of the upper template 21 is precisely connected with the lower template 22 to punch the raw material of the hardware shell and complete the punching process of the specific shape of the shell. This solves the problems of the upper and lower dies being difficult to move synchronously, the structure being complex, and the need for an additional power source.

[0018] Please see Figures 1-3A cylinder 24 is fixedly connected to the top plate 12, and the output end of the cylinder 24 is fixedly connected to the upper template 21. During operation, the cylinder 24 is started, and its output end directly drives the upper template 21 to move downward. The upper template 21 drives the upper rack 31 fixed to it to move downward synchronously, and the upper rack 31 drives the gear 33 to rotate. The gear 33 drives the lower rack 32 meshing with it to move upward, so that the lower template 22 and the upper template 21 can move in a precise and synchronous direction. This process is driven by only a single cylinder 24, combined with the gear 33-rack meshing transmission, to realize the automatic synchronous punching of the upper and lower dies, which solves the problems of asynchronous movement of the upper and lower dies, the need for additional power sources and complex structures in traditional punching equipment.

[0019] Please see Figures 1-3 The lower template 22 has a punch 25 fixedly connected to its top wall. The lower template 22 has a groove 26 located outside the punch 25, which is used to receive the waste generated during the punching process. During the punching process, the upper template 21 drives the punching cutter 23 to press down, working together with the punch 25 to complete the punching and forming of the metal shell. At the same time, the waste generated falls into the groove 26 outside the punch 25, which is uniformly received and collected. This design realizes the synchronous operation of punching and waste collection, which not only ensures the cleanliness of the working area and reduces the impact of waste accumulation on the synchronous movement accuracy of the upper and lower dies, but also improves the stability and production efficiency of the punching process.

[0020] Example 2: Please see Figures 1-5 This utility model provides a technical solution: A positioning component 4 is installed on the punch 25. The positioning component 4 includes several suction cups 41 and air pipes 42. The suction cups 41 are fixedly set in the recess of the top wall of the punch 25. The suction cups 41 are connected to the negative pressure device through the air pipes 42. The suction cups 41 are distributed in a rectangular array on the surface of the punch 25. During the punching process, when the metal shell sheet is placed on the surface of the punch 25, the negative pressure device is activated and provides negative pressure to the suction cups 41 through the air pipes 42, firmly adsorbing the sheet in the recessed area of ​​the top wall of the punch 25. The suction cups 41 distributed in a rectangular array work together to fix the sheet, making it less likely for the sheet to shift or deform during the punching process. The positioning component 4 automatically fixes the sheet before punching, which not only improves the punching accuracy but also ensures the stability of synchronous punching of the upper and lower dies, further improving the forming quality and production efficiency.

[0021] Please see Figures 1-3A number of limiting rods 13 are fixedly connected between the base 1 and the top plate 12. The upper template 21 and the lower template 22 are movably interlocked with the limiting rods 13. The limiting rods 13 are arranged in a rectangular array around the periphery of the upper template 21. During the punching process, the upper template 21 and the lower template 22 move precisely vertically relative to each other along the limiting rods 13 under the drive of the cylinder 24. The limiting rods 13 arranged in a rectangular array around the upper template 21 provide stable guiding constraints for the upper and lower templates 22, effectively limiting the horizontal offset and rotation of the templates during the movement. This design ensures that the upper and lower dies always maintain precise alignment during the punching process, which not only improves the punching accuracy and part consistency, but also ensures the reliable operation of the gear 33 and rack synchronous transmission system, thereby improving the stability of the equipment.
