Description

Technical Field

[0001] This utility model relates to the technical field of molds for busbar processing equipment, and specifically to a mold for busbar processing equipment. Background Technology

[0002] Busbar processing equipment is a key piece of equipment used in power equipment manufacturing for precise punching of busbars made of copper, aluminum, etc. One of its core components is the punching die, and the structural strength and stability of the die directly determine the punching quality, production efficiency, and service life of the equipment.

[0003] In existing technologies, such as Figures 1-2 As shown, the existing mold 5 used with the busbar processing equipment is a rectangular parallelepiped structure. The mold has a U-shaped slot 51 for accommodating the punch. A U-shaped base plate 52 is provided on the inner edge of the U-shaped slot 51. Long, narrow limiting slots 53 are provided on both sides of the mold. During installation, the mold is inserted into the mold slot of the punching machine, and the limiting pins of the busbar processing equipment tighten the limiting slots 53. During processing, the corresponding point between the punch and the busbar is observed through the U-shaped slot 51, allowing for accurate adjustment of the busbar's position. The control system of the busbar punching machine then drives the punch downwards to complete the punching.

[0004] However, in actual production, it was found that although this type of mold has a simple structure and low production cost, the U-shaped base plate 52 is a non-closed structure with an opening on one side, making its back side a region of high stress concentration. Under long-term, high-frequency impact loads, it is prone to metal fatigue, leading to cracks, deformation, and even breakage of the base plate, resulting in a very high failure rate. Each time the mold is damaged, it needs to be purchased from the manufacturer again, which not only increases production costs but also seriously affects the product quality and production efficiency of the busbar.

[0005] In order to ensure product quality and improve work efficiency, the applicant redesigned and developed a mold for busbar processing equipment. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a mold for busbar processing equipment.

[0007] A mold for busbar processing equipment includes a mold base. A stepped irregular perforation is formed through the middle of the mold base along its height direction. The irregular perforation includes an upper first hole segment and a lower second hole segment, which are connected. The cross-section of the first hole segment is circular, and its upper end penetrates the top surface of the mold base. The cross-section of the second hole segment is key-shaped, and its lower end penetrates the bottom surface of the mold base. The central axis of the first hole segment and the longitudinal axis of the second hole segment coincide.

[0008] A further technical solution is: the diameter of the first hole section is adapted to the punch fixing part of the busbar processing equipment, the width of the second hole section is 0.5 to 1 mm larger than the diameter of the punching rod of the busbar processing equipment, and the length of the second hole section is smaller than the diameter of the first hole section.

[0009] A further technical solution is: an observation groove with a top opening is opened on the top of the mold base along the longitudinal axis of the second hole section. One end of the observation groove penetrates the side wall of the mold base, and the other end is connected to the first hole section to form a channel for observing irregular perforations.

[0010] A further technical solution is that the height of the observation groove is less than the height of the first hole segment.

[0011] A further technical solution is to provide limiting holes on both sides of the mold base.

[0012] A further technical solution is as follows: the mold base is made of 45# steel with dimensions of 200mm*140mm*20mm. The first through hole is a round hole with a diameter of φ64mm and a depth of 16mm. The second through hole is a key-shaped through hole with a diameter of φ21mm and a depth of 37mm. The cross-sectional dimensions of the observation groove are 31*38mm and the depth is 10mm.

[0013] The beneficial effects of this utility model are: The mold of this application has a first hole section and a second hole section arranged in a stepped pattern in the middle of the mold base. The first hole section is used to accommodate the punch fixing part of the busbar processing equipment, and the second hole section is used for the punch bar of the busbar processing equipment to pass through. A long strip-shaped observation groove is opened on the top surface of the mold on one side of the first hole section. The position of the punch and the busbar can be easily observed through the observation groove and the second hole section to ensure that the punch accurately falls on the positioning point of the busbar during punching and to ensure the punching quality. The bottom surface of the mold base around the second hole section is a complete stress-bearing unit, which eliminates the stress concentration phenomenon at the connection between the U-shaped slot and the U-shaped base plate of the original mold, avoids the deformation and cracking problems caused by metal fatigue during the punching process, enhances the structural integrity of the mold, can withstand greater internal pressure and external load, and improves tensile strength.

[0014] Furthermore, positioning holes are opened on both sides of the mold base. These positioning holes cooperate with the limit pins of the busbar processing equipment to prevent the mold from shifting position during processing and ensure stability during the punching process.

[0015] The structure designed in this application solves the problem of easy damage to the mold during the punching process, which can ensure product quality and improve production efficiency. Attached Figure Description

[0026] The busbar processing equipment in this application is an existing finished product, and its implementation principle is based on existing technology, which will not be described in detail here. In a specific embodiment, the busbar processing equipment can be the BX30 portable hydraulic busbar processing equipment from Kunming Kunkai Special CNC Equipment Co., Ltd.

[0027] How to use this utility model: 1. First, place the mold of this application into the mold slot of the busbar processing equipment. After aligning the position, insert the two limit pins on both sides of the busbar processing equipment into the limit holes 4 on both sides of the mold and tighten them to fix the mold so that the mold will not shift position during the punching process and lock it in the corresponding processing position.

[0028] 2. Place the copper busbar on the workbench and slowly lower the mold by operating the control system of the busbar processing equipment until it stops about 5mm away from the upper surface of the copper busbar. This position is a preparatory position for safe observation and fine adjustment.

[0029] 3. Observe the position of the copper busbar below the second hole section 22 through the observation slot 3, and adjust the position of the copper busbar while observing to make the center point of the punching device consistent with the punching point of the copper busbar required by the drawing.

[0030] 4. After confirming that the position is correct, start the punching program, control the punching die to descend, and let the punching punch of the busbar processing equipment pass through the second hole section 22 to complete the punching operation.

[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
