Description

Technical Field

[0001] The embodiments of this utility model relate to the field of stamping equipment technology, specifically to a CNC busbar stamping machine for manufacturing distribution boxes and cabinets. Background Technology

[0002] With the rapid development of modern industry and the continuous advancement of urbanization, the application of power systems in various fields is becoming increasingly widespread and in-depth. As an indispensable and crucial component of the power system, distribution boxes and cabinets undertake key tasks such as distributing electrical energy, controlling circuits, and protecting electrical equipment. The improvement and innovation of distribution box and cabinet manufacturing technology are of paramount importance to ensuring the efficient operation of the power system.

[0003] In the manufacturing process of distribution boxes and cabinets, busbars, as key components used to collect, distribute, and transmit electrical energy, play a decisive role in the overall quality of the distribution boxes and cabinets due to their processing quality and precision. Busbar processing involves various techniques, among which stamping is one means of achieving a specific shape. CNC busbar stamping machines, as crucial equipment for busbar stamping, directly affect the processing quality and production efficiency of busbars, and consequently, the overall manufacturing level of the distribution boxes and cabinets.

[0004] During busbar processing, busbar plates often need to be stamped to bend them into specific angles to meet the complex electrical connection requirements inside distribution boxes and cabinets. Most stamping equipment on the market is designed for stamping busbars at a specific angle. These machines are equipped with bending heads of specific shapes and angles. During busbar processing, pressure is applied to the busbar plate through the bending head, causing it to bend at a preset angle. Because they can only process one angle, changing the bending head is necessary to process busbars at other angles, which is not only cumbersome and time-consuming but also increases equipment costs and reduces overall production efficiency.

[0005] Therefore, developing a CNC busbar punching machine that can flexibly meet various busbar bending angle requirements without frequent bending head replacements has become an important issue that urgently needs to be addressed in the field of distribution box and cabinet manufacturing. It is of great significance for improving the manufacturing quality and production efficiency of distribution boxes and cabinets. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this utility model provide a CNC busbar stamping machine for manufacturing distribution boxes and cabinets, which solves the technical problems of traditional stamping equipment in related technologies, where the bending angle is mostly fixed and the bending head needs to be replaced to meet different bending angle requirements, resulting in high cost and low production efficiency.

[0007] According to one aspect, at least one embodiment of the present invention provides a CNC busbar punching machine for manufacturing distribution box cabinets, including a frame, a lifting plate, a pressure plate and a top plate. The lifting plate is slidably disposed on the frame. There are two pressure plates disposed on the lifting plate, and the ends of the two pressure plates are hinged together. There are two top plates disposed on the frame, and the ends of the two top plates are hinged together. A guide rod is rotatably mounted on the top plate, and the guide rod is arranged vertically. A sliding sleeve is rotatably mounted on the pressure plate, and the sliding sleeve is slidably mounted on the guide rod. When the pressure plate swings, it can drive the top plate to swing synchronously with the help of the sliding sleeve and the guide rod, so that the angle between the two pressure plates is the same as the angle between the two top plates.

[0008] For example, in at least one embodiment of this utility model, a CNC busbar stamping machine for manufacturing distribution boxes and cabinets further includes: The bottom surface of the lifting plate is provided with two connecting rods that slide laterally. The two connecting rods are symmetrically arranged, and the bottom ends of the two connecting rods are respectively hinged to the two pressure plates.

[0009] For example, in at least one embodiment of this utility model, a CNC busbar stamping machine for manufacturing distribution boxes and cabinets further includes: A bidirectional screw is connected between the two connecting rods, and the two ends of the bidirectional screw are threaded to the two connecting rods respectively, for adjusting the angle between the two pressure plates.

[0010] For example, in at least one embodiment of this utility model, a CNC busbar stamping machine for manufacturing distribution boxes and cabinets further includes: A spring is connected between the lifting plate and the frame, and the spring is used to provide a force for the lifting plate to move away from the top plate.

[0011] For example, in at least one embodiment of this utility model, a CNC busbar stamping machine for manufacturing distribution boxes and cabinets further includes: The frame is equipped with a telescopic cylinder, which is located above the lifting plate and is used to apply downward sliding pressure to the lifting plate.

[0012] For example, in at least one embodiment of this utility model, a CNC busbar stamping machine for manufacturing distribution boxes and cabinets further includes: The frame is provided with a support rod below the top plate. The support rod is vertically arranged and can move vertically to abut against the bottom surface of the top plate.

[0013] For example, in at least one embodiment of this utility model, a CNC busbar stamping machine for manufacturing distribution boxes and cabinets further includes: The support rod is threaded onto the frame.

[0014] For example, in at least one embodiment of this utility model, a CNC busbar stamping machine for manufacturing distribution boxes and cabinets further includes: A baffle is slidably mounted on the frame along the lateral direction. The baffle is located on one side of the pressure plate and is used to abut the end of the raw material to position the stamping position of the raw material.

[0015] The beneficial effects of the embodiments of this utility model are as follows: In this invention, during the busbar bending operation, the busbar is placed between two pressure plates and two top plates. The lifting plate is lowered, and as it descends, the two pressure plates move downwards, applying pressure to the busbar. This causes the busbar to gradually deform, eventually bending it into a shape with the same angle as the pressure plates and top plates, thus completing the busbar bending process.

[0016] When the bending angle of the busbar needs to be adjusted, a relative oscillation is created between the two pressure plates. Since the sliding sleeves on the pressure plates are rotatably mounted on the guide rods of the top plate, when the pressure plates oscillate, the sliding sleeves slide on the guide rods, simultaneously causing the top plate to oscillate synchronously. This connection between the sliding sleeves and the guide rods ensures that the top plate can adjust its angle synchronously with the oscillation of the pressure plates, keeping the angle between the two pressure plates the same as the angle between the two top plates. In this way, different bending angles of the busbar can be achieved without changing the stamping head.

[0017] This CNC busbar punching machine allows for simple adjustment of the angle between the pressure plate and the top plate, meeting various busbar bending angle requirements without changing the punch head, thus improving the equipment's versatility. The machine adjusts the angle through the synchronous swinging of the pressure plate and top plate, making operation simple and quick, reducing downtime caused by changing the punch head, and improving production efficiency.

[0027] like Figure 1The diagram illustrates a CNC busbar stamping machine for manufacturing distribution boxes and cabinets according to one embodiment of the present invention. The machine includes a frame 1, a lifting plate 2, a pressure plate 3, and a top plate 4. The frame 1 is the basic support structure of the entire CNC busbar stamping machine. The lifting plate 2 is slidably mounted on the frame 1. There are two pressure plates 3, mounted on the lifting plate 2. One end of the two pressure plates 3 is hinged together by a hinge shaft, forming a V-shaped structure. A sliding sleeve 6 is rotatably mounted on the pressure plate 3. Similarly, there are two top plates 4, mounted on the frame 1, and one end of the two top plates 4 is also hinged together by a hinge shaft, forming an overall V-shaped structure that matches the shape of the pressure plates 3. A guide rod 5 is rotatably mounted on the top plate 4 corresponding to the position of the sliding sleeve 6 of the pressure plate 3. The guide rod 5 is vertically positioned, and the sliding sleeve 6 is slidably mounted on the guide rod 5.

[0028] Working principle: During the busbar bending operation, the busbar is placed between two pressure plates 3 and two top plates 4. The lifting plate 2 is lowered, and as the lifting plate 2 descends, the two pressure plates 3 move downwards accordingly, applying pressure to the busbar, causing the busbar to gradually deform and eventually bend into a shape with the same angle as the pressure plates 3 and top plates 4, thus completing the busbar bending process.

[0029] When the bending angle of the busbar needs to be adjusted, a relative swing is generated between the two pressure plates 3. Since the sliding sleeve 6 on the pressure plate 3 is rotatably mounted on the guide rod 5 of the top plate 4, when the pressure plate 3 swings, the sliding sleeve 6 slides on the guide rod 5, simultaneously causing the top plate 4 to swing synchronously. This connection between the sliding sleeve 6 and the guide rod 5 ensures that the top plate 4 can adjust its angle synchronously with the swing of the pressure plate 3, so that the angle between the two pressure plates 3 always remains the same as the angle between the two top plates 4. In this way, different bending angles of the busbar can be achieved without changing the stamping head.

[0030] This CNC busbar punching machine allows for simple adjustment of the angle between the pressure plate 3 and the top plate 4, enabling it to meet various busbar bending angle requirements without changing the punch head, thus improving the equipment's versatility. The machine adjusts the angle through the synchronous swinging of the pressure plate 3 and the top plate 4, making operation simple and quick, reducing downtime caused by changing the punch head, and improving production efficiency.

[0031] In some examples, the bottom surface of the lifting plate 2 has a transverse groove, and two connecting rods 9 are symmetrically arranged within the groove and can slide within it. The top of each connecting rod 9 is machined with a slider adapted to the groove; the sliding of the connecting rod 9 on the bottom surface of the lifting plate 2 is achieved through the cooperation of the slider and the groove. The bottom end of the connecting rod 9 is hinged to the pressure plate 3 via a hinge shaft. A bidirectional screw 8 connects the two connecting rods 9; both ends of the bidirectional screw 8 are machined with threads of opposite directions, and the bidirectional screw 8 is threadedly connected to the connecting rods 9 through these threads.

[0032] Working Principle: When adjusting the angle between the two pressure plates 3, the operator rotates the bidirectional screw 8. Since the threads at both ends of the bidirectional screw 8 rotate in opposite directions, during rotation, the two connecting rods 9, threaded to both ends of the bidirectional screw 8, move towards or away from each other along the groove on the bottom surface of the lifting plate 2. Because the bottom end of the connecting rod 9 is hinged to the pressure plate 3, the lateral movement of the connecting rod 9 causes the pressure plate 3 to swing around the hinge point, thereby changing the angle between the two pressure plates 3. When the lifting plate 2 descends to press the busbar, the connecting rod 9 can transmit the pressure of the lifting plate 2 to the pressure plate 3, ensuring that the pressure plate 3 applies pressure to the busbar. When adjusting the angle of the pressure plate 3, the connecting rod 9 can also convert the rotational motion of the bidirectional screw 8 into the swinging motion of the pressure plate 3.

[0033] In some examples, a spring 10 is connected between the frame 1 and the lifting plate 2, providing elastic force to tend the lifting plate 2 away from the top plate 4. A telescopic cylinder 11 is mounted on the frame 1 above the lifting plate 2. The piston rod of the telescopic cylinder 11 points downwards, and its end is connected to the lifting plate 2.

[0034] Working principle: Spring 10 acts as a buffer and reset mechanism. After the telescopic cylinder 11 pushes the lifting plate 2 downward to complete the busbar stamping, the telescopic cylinder 11 retracts its piston rod. At this time, due to its own elastic restoring force, spring 10 provides an upward force to the lifting plate 2, helping the lifting plate 2 to smoothly return to its initial position.

[0035] When the busbar needs to be stamped, the telescopic cylinder 11 pushes the piston rod to extend downwards. The piston rod transmits pressure to the lifting plate 2, which overcomes the elastic force of the spring 10, causing the lifting plate 2 to move downwards with the pressure plate 3, applying pressure to the busbar placed between the pressure plate 3 and the top plate 4, thereby realizing the stamping and bending of the busbar.

[0036] In some examples, the frame 1 has a support rod 12 below the top plate 4. The support rod 12 is arranged vertically and is connected to the frame 1 by threads, allowing it to move vertically by rotation. The top of the support rod 12 can stably abut against the top plate 4, providing support for the top plate 4 and enhancing its stability during the stamping process.

[0037] A baffle 13 is slidably mounted on the frame 1 along its transverse direction. The baffle 13 is located on one side of the pressure plate 3 and abuts against the end of the busbar material. Before the busbar stamping operation, the busbar material is placed on the top of the two top plates 4, and then the end of the busbar material is abutted against the baffle 13. This determines the transverse position of the busbar material, thus positioning the stamping position. When faced with different busbar bending requirements, the operator can adjust the bending position of the busbar material by sliding the baffle 13, changing the relative position between the end of the busbar material and the pressure plate 3 to meet diverse production requirements.

[0038] Working principle: During the stamping process, the support rod 12 provides upward support force, enhancing the structural stability of the top plate 4. When the top plate 4 changes angle, the support rod 12 can be rotated, and the threaded action can be used to move the support rod 12 vertically, thereby re-engaging with the top plate 4.

[0039] The baffle 13 changes its position on the frame 1 by sliding laterally. After the end of the busbar material abuts against the baffle 13, the baffle 13 restricts the movement of the busbar in the lateral direction, thus determining the position of the busbar material. By adjusting the position of the baffle 13, the bending position of the busbar material under the action of the pressure plate 3 can be changed, thereby achieving effective positioning of the busbar stamping position.
