Description

Technical Field

[0001] This utility model relates to the field of irregular copper busbar production technology, and in particular to an irregular copper busbar processing device. Background Technology

[0002] Copper busbars are characterized by high electrical conductivity, excellent thermal conductivity, and high structural strength. They are commonly used in power electronic equipment (such as inverters, frequency converters, and other high-power devices), new energy vehicles (such as the connecting busbars of lithium battery packs), and industrial equipment (such as high-power motor drives).

[0003] However, existing irregularly shaped copper busbars, such as those with a "U"-shaped structure (where the cross-section of the busbar body is concave and the surface has evenly spaced heat dissipation holes to increase the air contact area and improve heat dissipation efficiency), are currently manufactured by punching holes in the copper busbar and then bending it into the required structure. However, this method has the following drawbacks: 1. Burrs or stress concentrations exist at the punched edges. When the punched area is close to the bending point, the local stress during bending may exceed the material's bearing capacity, leading to cracks at the punched edges or in the bending area; 2. The material surface is rough or contains impurities after punching, causing scratches due to friction with the mold during bending.

[0004] To address the aforementioned shortcomings, we designed a special-shaped copper busbar processing device that uses a bending-then-punching process. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses an irregular copper busbar processing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An apparatus for processing irregularly shaped copper busbars, comprising:

[0008] The supporting beam has two sliding groups symmetrically spaced apart;

[0009] The replaceable support base has two parts, each of which can be detachably installed on two sliding groups;

[0010] An adjustment component, located at the bottom of the support beam, is used to adjust the distance between the two sliding groups;

[0011] The support beam and two replaceable support bases form a U-shaped top surface to facilitate workpiece fitting and embedding.

[0012] Furthermore, the sliding assembly includes two sliders located on the two side walls of the support beam, and the sliders are slidably connected to the support beam along the longitudinal direction.

[0013] Furthermore, both sides of the support beam are provided with linear slide rails along their longitudinal direction, and the slider is slidably connected to the side wall of the support beam through the corresponding linear slide rails.

[0014] Furthermore, the adjustment component includes:

[0015] The adjusting screw is connected to the bottom of the support beam by rotating longitudinally, and the two sections of its thread have opposite helical directions.

[0016] The threaded slider has two parts, each threadedly engaged with the two threads of the adjusting screw.

[0017] The threaded slider has outward extensions on both sides of its bottom, and the extensions are connected to the corresponding sliders.

[0018] Furthermore, the bottom surface of the support beam is provided with a recessed portion to accommodate the adjusting screw; both ends of the adjusting screw penetrate through the sidewall of the recessed portion and extend outwards, and the end of the adjusting screw is provided with a rotating handle.

[0019] Furthermore, one end of the replaceable support is connected to the top of the slider in the corresponding sliding group via a transverse sliding plug-in structure, and the other end is attached to the top surface of another slider in the corresponding sliding group and connected by a locking bolt.

[0020] Furthermore, the transverse sliding plug structure includes a sliding groove disposed transversely on the top surface of the corresponding slider and a sliding plug block disposed at one end of the support base.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This processing device can perform a process sequence of bending before punching: by setting the bending process before the punching process, it effectively avoids the problem of cracks in the bending area caused by burrs and stress concentration at the punching edge in the traditional process. In addition, the surface of the copper busbar after bending is smoother, and the frictional resistance with the mold during bending is significantly reduced, thereby reducing surface roughening and improving the surface quality of the finished product.

[0023] 2. By adjusting the screw to drive the sliding group to move laterally, the distance between the two replaceable support seats can be quickly adjusted to adapt to different sizes of irregular copper busbar workpieces without replacing the entire set of equipment, which significantly improves production efficiency. Furthermore, the sliding plug-in block and slide groove matching structure of the replaceable support seat, as well as the single-sided fixing by locking bolts, facilitates the quick installation and disassembly of the replaceable support seat, adapting to diverse irregular copper busbar processing needs.

[0029] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0030] Example 1, in conjunction with Appendix Figure 1-4 An apparatus for processing irregularly shaped copper busbars, comprising:

[0031] The support beam 1 is a long strip structure, with linear slide rails 11 along both sides of its longitudinal direction. The bottom of the support beam 1 has a recess 12 to accommodate the adjustment component 3.

[0032] The sliding assembly includes two sliders 4, which are respectively installed on the linear slide rails 11 on both sides of the support beam 1.

[0033] Among them, two sliders 4 moving in the same direction form a sliding group, combined with the attached Figure 3 The two sliders 4 on the left form a sliding group, and the two sliders 4 on the right form a sliding group. The two sliding groups are symmetrically spaced as needed, meaning that the two sliding groups are equidistant from the longitudinal center of the support beam 1.

[0034] Furthermore, in conjunction with the appendix Figure 3 and 4The top of the front slider 4 in the sliding assembly is provided with a groove 41 for cooperating with the sliding plug block 21 of the replaceable support 2. The top surface of the rear slider 4 is provided with a threaded hole, and the other end of the replaceable support 2 is fixed by the locking bolt 5, so as to finally realize the positioning and locking operation of the replaceable support 2.

[0035] Replaceable support base 2: Two replaceable support bases 2 are respectively installed on the top of the sliders 4 of the two sliding groups. The sliding plug 21 of the replaceable support base 2 is embedded in the sliding groove 41 of the front slider 4 and its position is adjusted by sliding laterally; the other end is connected to the threaded hole of the front and rear sliders 4 through the locking bolt 5.

[0036] With this configuration, the top and inner surfaces of the two replaceable support seats 2 and the top surface of the support beam 1 are located between the two replaceable support seats 2 to form a U-shaped structure, which is used to match the U-shaped irregular copper busbar workpiece.

[0037] Furthermore, both the replaceable support base 2 and the support beam 1 are provided with multiple vertical punched slots spaced along the longitudinal direction.

[0038] In one possible implementation, the regulating component 3 includes:

[0039] An adjusting screw 31 extends longitudinally through the recess 12 at the bottom of the support beam 1, and has threaded sections in opposite directions at its two ends. A rotating handle 33 is provided at the end of the adjusting screw 31 for easy manual adjustment.

[0040] Threaded sliders 32: Two threaded sliders 32 are respectively threaded onto the two sections of the thread on the adjusting screw 31. Each threaded slider 32 has an extension 321 on both sides of its bottom, and the extension 321 is mechanically connected and fixed to the slider 4 in the sliding assembly.

[0041] The top surface of the "U"-shaped structure: By adjusting the rotation of the adjusting screw 31, the sliding groups on both sides drive the replaceable support base 2 to move laterally, ultimately making the support beam 1 and the two replaceable support bases 2 form the top surface of the "U"-shaped structure (see attached). Figure 1 In order to embed irregularly shaped copper busbar workpieces

[0042] Operating procedures

[0043] Adjusting the spacing: By rotating the rotating handle 33 of the adjusting screw 31, the reverse movement of the threaded slider 32 drives the sliding groups on both sides to move inward or outward, thereby adjusting the spacing between the two replaceable support seats 2 to match the irregular copper busbar workpieces of different sizes.

[0044] Replacement of replaceable support 2: Select the appropriate replaceable support 2 according to the workpiece. First, slide the sliding plug 21 of the replaceable support 2 horizontally from the outside to the inside into the corresponding slide groove 41 on the top surface of the slider 4. Then, connect the other end of the replaceable support 2 to the threaded hole of the other slider 4 of the sliding group by locking bolt 5 to complete the installation of the replaceable support 2.

[0045] Processing procedure: The irregularly shaped copper busbar is embedded into the top surface of the "U"-shaped structure. A punching machine is used to punch holes in the bent copper busbar, or the copper busbar is first bent into shape using a bending machine, and then holes are punched in the bent copper busbar using a punching machine.

[0046] Because bending occurs before punching, this avoids the problems in existing technologies where, during bending, burrs or stress concentration exist at the edge after punching, and when the punching position is close to the bending area, the local stress of the material during bending may exceed its bearing capacity, leading to cracks at the punching edge or bending area. It also avoids the problems of rough material surface or impurities after punching, which cause burrs and stress concentration at the edge due to friction with the mold during bending.

[0047] Example 2: An irregular copper busbar processing device, which is further optimized based on Example 1: The support beam 1 is provided with a scale, so that the distance between the two replaceable support seats 2 can be easily known.

[0048] It should be noted that since the punching spacing and hole diameter of copper busbars of the same width are basically the same, this processing device can adapt to the adjustment of different recess lengths and depths, and its applicability will not be affected by changes in size.

[0049] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
