Description

Technical Field

[0001] This utility model relates to the field of power equipment manufacturing technology, specifically to a U-shaped copper busbar bending mold used in the gas box of a gas-filled cabinet. Background Technology

[0002] Copper busbar bending is a processing technology that uses hydraulic or mechanical drives to plastically deform copper busbars using molds. Currently available copper busbar bending molds have limitations: a bending radius that is too small can lead to insufficient copper busbar strength; springback can affect the stability of the bending angle; uneven mold clearance can affect processing accuracy; and slippage can easily occur when processing thin plates.

[0003] For bending U-shaped copper busbars, some processes still rely on universal molds and multiple manual adjustments to complete the bending process. This method is time-consuming and labor-intensive, and is also susceptible to bending errors due to equipment and human factors. Therefore, bending must be performed in a controllable and appropriate manner to ensure the safe and reliable operation of the gas-insulated switchgear. Based on technical requirements and production needs, designing a U-shaped copper busbar bending mold is imperative. Utility Model Content

A sliding limiting plate is provided on the side of the main frame, and the limiting distance of the first limiting baffle to the lower end of the side of the copper busbar is controlled by the sliding limiting plate.

[0009] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, in the following descriptions, well-known structures and technologies have been omitted to avoid unnecessary confusion regarding the concept of this utility model.

[0011] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0012] like Figure 1 The U-shaped copper busbar bending mold shown includes a main frame 100, and an upper cover plate 110 is provided at the upper end of the main frame 100.

[0013] The main frame 100 has a first side plate 120 and a first side sealing plate 140 on both sides, and a second side plate 130 and a second side sealing plate 150.

[0014] The lower end of the upper cover plate 110 is provided with an upper mold 160 that moves up and down. The upper mold 160 is connected to the press slide (not shown in the figure) and is responsible for pressing the copper busbar downward.

[0015] The copper busbar stamping surface 161 of the upper mold 160 is a hardened copper busbar stamping surface.

[0016] A first lower mold 170 and a second lower mold 190 are provided at the lower end of the main frame 100, with the first lower mold 170 located at the upper end of the second lower mold 190.

[0017] The first lower mold contact groove 171 of the first lower mold 170 and the second lower mold contact groove 191 of the second lower mold 190 together form the bending reference surface of the U-shaped copper busbar. The groove size is adjusted according to the thickness of the copper busbar and the bending radius.

[0018] A sliding limit plate 220 is provided on the side of the main frame 100, and the sliding limit plate 220 is used to control the limiting distance of the first limit baffle 200 to the lower end of the side of the copper busbar.

[0019] The sliding limit plate 220 slides along the sliding mechanism 231 provided on the base plate 230.

[0020] The upper limit distance of the side of the copper busbar is controlled by a second limit baffle 180 installed on the main frame 100.

[0021] The first lower mold 170 and the second lower mold 190, the second limiting baffle 200, the first limiting baffle 180 and the side plate are fixedly engaged with each other by the limiting pin 210.

[0022] The limiting pin 210 needs to be precisely inserted into the preset holes of the first lower mold 170 and the second lower mold 190, and at the same time pass through the corresponding mating holes on the second limiting baffle 200, the first limiting baffle 180, the first side plate 120, and the second side plate 130.

[0023] The second limiting baffle 200 and the first limiting baffle 180 are locked to the lower part and side plate of the mold by means of limiting pins to ensure that the limiting height and angle of the copper busbar are not deviated due to external force.

[0024] The side plate is linked to the lower part of the mold and the limiting baffle through the limiting pin, which enhances the overall structural stability and prevents the mold components from shaking when bending.

[0025] The limiting pin uses the mechanical principle of "pin positioning" to make the lower load-bearing module, lateral support module and limiting control module of the mold form an integrated fixed cooperation, which ensures the accuracy and operational stability of copper busbar bending from the structural level.

[0026] This utility model's mold features a compact structure, simple operation, high efficiency, detachability, and small space occupation. It is suitable for factories producing U-shaped copper busbars for various gas holder gas boxes and is an essential mold for bending these busbars. Its unique design facilitates assembly and disassembly, and the mold can be upgraded by replacing components.

[0027] The sliding limit plate 220 is installed on the side of the main frame and its position can be adjusted by the limit baffle 200 to control the bending length of a section of the copper busbar, adapting to different size processing requirements. There are two sets of limit baffles 180 and 200, one above and one below, which cooperate with the sliding limit plate 220 to position the side of the copper busbar and prevent the copper busbar from shifting during bending.

[0028] The base plate 230 serves as the foundation support for the mold, supporting the first lower mold 170 and the second lower mold 190 on the top, and connecting to the first side plate 120 and the second side plate 130 on the left and right respectively, and connecting to the press worktable on the bottom to ensure the overall installation is stable.

[0029] Because of the above structure, the working principle of this utility model is as follows: The U-shaped copper strip to be bent is placed on the first lower mold 170 and the second lower mold 190.

[0030] Adjust the position of the sliding limit plate 220 so that one end of the copper busbar abuts against the sliding limit plate 220 and the other side is in close contact with the second limit baffle 180 and the first limit baffle 200. Fine-tune the position of the sliding limit plate 220 through the first limit baffle 200 to match the size requirements of the drawing. The press is started, and the upper mold 160 presses the copper busbar downward. The copper busbar is bent and formed under the combined action of the first lower mold 170 and the second lower mold 190.

[0031] The above shows and describes the basic principles, main features, and advantages of this utility model.

[0032] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of this utility model as defined by the appended claims and their equivalents.
