Description

Technical Field

[0001] This utility model relates to a mold, specifically a pressing mold for bending connecting busbars of superconducting aluminum alloy. Background Technology

[0002] A busbar refers to the connection between various voltage distribution devices in a substation, as well as the connection between electrical equipment such as transformers and their corresponding distribution devices. Most busbars use bare conductors or stranded wires with rectangular or circular cross-sections; these are collectively called busbars. The function of a busbar is to collect, distribute, and transmit electrical energy. In a power system, busbars connect the various current-carrying branch circuits in the distribution devices, playing the role of collecting, distributing, and transmitting electrical energy.

[0003] To meet the power distribution connection requirements, the aluminum alloy busbars need to be manufactured as follows: Figure 5 As shown, the aluminum alloy busbar is irregularly shaped and curved, with both ends flattened. Currently, the traditional manufacturing process for irregularly shaped curved aluminum alloy busbars typically involves initially bending the raw material using a bending machine, then flattening both ends in the next process, and finally machining the various arc surfaces. Due to the special shape, the arc surfaces cannot be machined using the aluminum alloy busbar itself; they must be processed manually. These steps result in multiple processes required to complete the production of irregularly shaped curved aluminum alloy busbars, leading to low production efficiency and affecting machining accuracy. Utility Model Content

[0004] This utility model provides a pressing mold for bending and connecting superconducting aluminum alloy busbars. Its main purpose is to overcome the problems of low production efficiency and low processing accuracy of aluminum alloy busbars caused by the use of traditional processing methods for irregularly shaped bent aluminum alloy busbars.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A superconductor aluminum alloy bending connection busbar pressing die includes a fixed die support plate, a fixed die core, and a moving die. The fixed die core is fixedly connected to the top surface of the fixed die support plate. The moving die is located above the fixed die core, and the bottom surface of the moving die is adapted to the top surface of the fixed die core. The top surface of the fixed die core is provided with a lower busbar irregular groove, and the two ends of the lower busbar irregular groove are respectively provided with a first lower flat groove and a second lower flat groove. The bottom surface of the moving die is provided with an upper busbar irregular groove, and the two ends of the upper busbar irregular groove are respectively provided with a first upper flat groove and a second upper flat groove.

[0007] Furthermore, the lower busbar irregular groove includes a first lower transverse groove, a lower inclined groove, and a second lower transverse groove connected in sequence. The first lower flat groove is located at the left end of the first lower transverse groove, and the second lower flat groove is located at the right end of the second lower transverse groove. The connection between the first lower flat groove and the first lower transverse groove is a rounded transition. The connection between the first lower transverse groove and the lower inclined groove is a rounded transition. The connection between the lower inclined groove and the second lower transverse groove is a rounded transition. The connection between the second lower transverse groove and the second lower flat groove is a rounded transition.

[0008] Furthermore, the upper busbar irregular groove includes a first upper transverse groove, an upper inclined groove, and a second upper transverse groove connected in sequence. The first upper flat groove is located at the left end of the first upper transverse groove, and the second upper flat groove is located at the right end of the second upper transverse groove. The connection between the first upper flat groove and the first upper transverse groove is rounded, the connection between the first upper transverse groove and the upper inclined groove is rounded, the connection between the upper inclined groove and the second upper transverse groove is rounded, and the connection between the second upper transverse groove and the second upper flat groove is rounded.

[0009] Furthermore, the top left end of the fixed mold core is provided with two lower positioning pins arranged front to back, the top right end of the fixed mold core is provided with two lower positioning grooves arranged front to back, the bottom left end of the moving mold is provided with two upper positioning grooves arranged front to back, and the bottom right end of the moving mold is provided with two upper positioning pins arranged front to back. Each lower positioning pin corresponds to one upper positioning groove, and each upper positioning pin corresponds to one lower positioning groove. When the moving mold and the fixed mold core are closed, the lower positioning pins are located in the upper positioning grooves, and the upper positioning pins are located in the lower positioning grooves.

[0010] As described above, compared with the prior art, this utility model has the following advantages: When processing irregularly shaped curved aluminum alloy busbars, the raw material is first initially bent using a bending machine. Then, the initially bent aluminum alloy busbar is placed in the lower busbar irregular groove. Next, the moving mold descends and closes with the fixed mold core. After mold closure, the lower and upper busbar irregular grooves press the aluminum alloy busbar into an irregularly curved shape that meets the precision requirements. At the same time, the first upper flat groove, the first lower flat groove, the second upper flat groove, and the second lower flat groove respectively press the two ends of the aluminum alloy busbar into a flat shape. This utility model shortens the processing time of irregularly shaped curved aluminum alloy busbars, greatly improves the processing efficiency of aluminum alloy busbars, and ensures the production precision of aluminum alloy busbars by using mold pressing.
