Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and in particular to a shaping device for rectifier module electrode sheets. Background Technology

[0002] like Figure 1 As shown, a rectifier module electrode a includes a vertical section a1, a first horizontal section a2, a bridging section a3, and a second horizontal section a4. One end of the first horizontal section is connected to the vertical section, and the other end is connected to the second horizontal section via the bridging section. During production, the electrode is first bent and then annealed. However, during annealing, atomic activity increases, and stress is gradually released through creep and diffusion. The electrode springs back in the direction of reduced stress, causing significant deformation (right-angle opening or closing) of the angle between the vertical section and the first horizontal section, affecting subsequent assembly work. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a shaping device for rectifier module electrodes that can correct product deformation and prevent it from affecting subsequent assembly work.

[0004] To achieve the above objectives, the technical solution adopted by the rectifier module electrode shaping device of this utility model is as follows:

[0005] A shaping device for rectifier module electrode sheets includes a backing plate, a first pressure plate, and a second pressure plate. The first pressure plate has at least one set of diagonally arranged limiting posts that penetrate the backing plate. The backing plate is movably connected to the first pressure plate through the limiting posts. The backing plate and the first pressure plate cooperate to press the vertical section together, and the backing plate and the second pressure plate cooperate to press the first horizontal section together.

[0006] Preferably, a spring is provided between the backing plate and the first pressure plate, which is sleeved on the outside of the limiting post.

[0007] Preferably, the side wall of the backing plate facing the first pressure plate has a plurality of positioning slots, the bottom surface of the positioning slots is the backing surface of the vertical section, and the side wall of the first pressure plate facing the backing plate has a plurality of pressing protrusions, the pressing protrusions corresponding one-to-one with the positioning slots.

[0008] Preferably, the side wall of the backing plate facing away from the first pressure plate is provided with a plurality of clearance grooves, and the clearance grooves correspond one-to-one with the positioning slots.

[0009] Preferably, both the positioning slot and the clearance slot are strip-shaped through slots.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] When the angle between the vertical section and the first horizontal section increases, the vertical section is first pressed down using the backing plate and the first pressure plate, and then the first horizontal section is flattened using the second pressure plate. When the angle between the vertical section and the first horizontal section decreases, the first horizontal section is first pressed down using the backing plate and the second pressure plate, and then the vertical section is flattened using the first pressure plate. This ensures that the annealed electrode sheet is properly aligned for subsequent assembly. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0018] like Figure 2-4As shown, a shaping device for rectifier module electrode sheets includes a backing plate 1, a first pressure plate 2, and a second pressure plate 3. The backing plate, first pressure plate, and second pressure plate are all made of rectangular plates. Two sets of diagonally mounted limiting posts 4 penetrate the backing plate on the first pressure plate. The limiting posts are bolts, which pass through the backing plate and are fixed to the first pressure plate. The bolt heads prevent the backing plate from slipping. The backing plate is movably connected to the first pressure plate via the limiting posts. A spring 5, sleeved on the outside of the limiting posts, is installed between the backing plate and the first pressure plate. Before shaping, the spring opens the first pressure plate and the backing plate to facilitate the insertion of the vertical section. After shaping, the spring opens the first pressure plate and the backing plate again to facilitate the removal of the vertical section. Three positioning slots 11 are formed on the side wall of the back plate facing the first pressure plate. The bottom surface of the positioning slots is the vertical back surface. Three pressing bosses 21 are machined on the side wall of the first pressure plate facing the back plate. The pressing bosses correspond one-to-one with the positioning slots. Three clearance slots 12 are formed on the side wall of the back plate away from the first pressure plate. The clearance slots correspond one-to-one with the positioning slots. Both the positioning slots and clearance slots are strip-shaped through slots. Both ends of the through slots can be used to improve convenience. Setting multiple positioning slots can shape multiple electrode sheets at the same time to improve work efficiency. The positioning slots and clearance slots can limit the large displacement of the electrode sheets, avoid large skew of the electrode sheets, and improve the shaping quality.

[0019] It should be noted that the positioning slots and clearance slots in this embodiment can be processed according to the requirements of different electrode sheets, that is, three identical electrode sheets can be shaped at one time, or three different electrode sheets can be shaped at one time.

[0020] The specific working process of a rectifier module electrode shaping device is as follows: When the angle between the vertical section and the first horizontal section increases, the vertical sections of the three electrodes are sequentially inserted between the positioning slot and the clamping boss. First, the first pressure plate is pressed down, and the clamping boss and the backing surface cooperate to clamp the vertical section. Then, the second pressure plate is used to press each of the first horizontal sections onto the outer wall of the backing plate. When the angle between the vertical section and the first horizontal section decreases, the vertical sections of the three electrodes are sequentially inserted between the positioning slot and the clamping boss. First, the second pressure plate is used to press each of the first horizontal sections onto the outer wall of the backing plate. Then, the first pressure plate is pressed down, and the clamping boss and the backing surface cooperate to clamp the vertical section. This invention, based on the relatively soft nature of the electrodes (the electrode material is copper), allows for manual correction through the cooperation between the backing plate and the first and second pressure plates. This is flexible and convenient, preparing for subsequent assembly work and improving production efficiency.
