Description

Technical Field

[0001] This utility model relates to the technical field of capacitor processing equipment, specifically to a capacitor lead bending and cutting device. Background Technology

[0002] A capacitor is an electronic component used to store electrical charge and regulate voltage and current fluctuations in a circuit through the electric field effect. The basic working principle of a capacitor is that it consists of two insulated conductors (plates) separated by a dielectric material. When a voltage is applied across the capacitor, it stores electrical charge; when the circuit needs electrical energy, it releases the stored charge, thus stabilizing the voltage or current.

[0003] A capacitor consists of a capacitor body, capacitor leads connecting the capacitor body, and protruding corners on the capacitor body. The capacitors arriving in the market are in a standard state and do not match the product specifications. After the capacitor materials arrive, they need further processing to be compatible with production, specifically bending and cutting the capacitor leads. Currently, this work is mainly done manually. Manual processing requires highly skilled operators, is prone to fatigue, leads to reduced operational accuracy, inconsistent bending angles and cutting lengths, poor consistency, and low efficiency. Utility Model Content

[0004] The present invention aims to provide a capacitor lead bending and cutting device to replace manual bending and cutting of capacitor leads, so as to ensure that the bending angle and cutting length are consistent.

[0005] To solve the above problems, this utility model provides the following technical solution:

[0006] A capacitor lead bending and cutting device includes an upper die, a lower die, and a support. The support is equipped with a cylinder that drives the upper die to move toward the lower die. The lower die and the support are fixedly connected. The upper die is fixedly equipped with a cutter. The upper die is also symmetrically equipped with a sliding groove along the cutter. A pressure plate is vertically slidably connected to the sliding groove. A limiting spring is fixed between the pressure plate and the sliding groove. The pressure plate extends directly below the cutter. The lower die is equipped with a bending groove directly opposite the cutter.

[0007] The working principle and beneficial effects of this utility model:

[0008] This technical solution places the capacitor on the lower mold, with the capacitor leads spanning the bending groove. The upper mold, driven by the starter cylinder, moves toward the lower mold, while the cutter and pressure plate move toward the capacitor simultaneously. The pressure plates on both sides first contact the capacitor leads, and the compression spring generates elastic force to press the leads tightly. Then, the cutter moves downward to press the capacitor leads into the bending groove, thus achieving the cutting and bending of the capacitor leads.

[0009] This solution uses a pressure plate and a cutter to bend and trim the capacitor leads to ensure that the bending angle and trimming length remain consistent.

[0010] Furthermore, the lower mold is equipped with positioning holes that mate with the protruding corners on the capacitor body. When the capacitor body is placed on the lower mold, the protruding corners on the capacitor body are inserted into the positioning holes for quick positioning, which facilitates subsequent bending and cutting.

[0011] Furthermore, the cutter includes a cutting surface near one pressure plate and a bending surface near the other pressure plate. The cutting surface is used to trim excess length of the capacitor leads, and the bending surface is used to bend the capacitor leads toward the capacitor body.

[0012] Furthermore, the lower mold is fixedly equipped with a sliding rod, and the upper mold and the sliding rod are slidably connected. The sliding rod limits the sliding trajectory of the upper mold, making its up-and-down sliding smoother.

[0013] Furthermore, one side pressure plate is used to press the end of the capacitor pin away from the capacitor body, and the other side pressure plate is used to press the end of the capacitor pin close to the capacitor body.

[0014] Furthermore, the bending surface is located directly above the bending groove. Attached Figure Description

[0018] Figure 4 This is a schematic diagram of the structure when the pressure plate clamps the capacitor pins;

[0019] Figure 5 A schematic diagram of the structure when bending and cutting the capacitor leads. Detailed Implementation

[0020] The following detailed description illustrates the specific implementation method:

[0021] The reference numerals in the accompanying drawings include: lower mold 1, upper mold 2, cylinder 3, bracket 4, pressure plate 5, cutter 6, capacitor body 7, positioning hole 8, capacitor pin 9, convex corner 10, bending groove 11, slide groove 12, and spring 13.

[0022] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.

[0023] Example: A capacitor lead bending and cutting device, such as Figure 1 and Figure 2 As shown, it includes an upper mold 2, a lower mold 1 and a bracket 4. The bracket 4 is fixedly equipped with a cylinder 3 that drives the upper mold 2 to move toward the lower mold 1. The lower mold 1 and the bracket 4 are fixedly connected.

[0024] A cutter 6 is fixedly provided at the bottom of the upper mold 2, such as Figure 4 As shown, the cutter 6 includes a cutting surface located on its bottom left and a bending surface located on its bottom right. The upper mold 2 is also provided with symmetrical sliding grooves 12, and a pressure plate 5 is vertically slidably connected to the sliding grooves 12. A limiting spring 13 is fixed between the pressure plate 5 and the sliding grooves 12, and the pressure plate 5 extends directly below the cutter 6. The lower mold 1 is provided with a bending groove 11 opposite to the cutter 6 and a positioning hole 8 that cooperates with the convex corner 10 on the capacitor body 7.

[0025] like Figure 3 As shown, in this technical solution, the protruding corner 10 on the capacitor body 7 is placed into the positioning hole 8 to achieve the positioning of the capacitor body 7. The capacitor lead 9 spans across the top of the bending groove 11. The cylinder 3 is activated to drive the upper mold 2 to move towards the lower mold 1, as shown. Figure 4 As shown, the cutter 6 and the pressure plate 5 move downwards towards the capacitor body 7 synchronously. The pressure plates 5 on both sides first contact the capacitor leads 9, thus fixing both ends of the capacitor leads 9. The cutter 6 and the pressure plate 5 continue to move downwards synchronously, and the lower mold 1 squeezes the pressure plate 5, causing the pressure plate 5 to slide upwards within the slide groove 12. The pressure plate 5 compresses the spring 13, generating elastic force, which causes the pressure plate 5 to press the capacitor leads 9 tightly. Figure 5 As shown, the cutter 6 then presses the capacitor lead 9 downwards into the bending groove 11. The cutting surface on the left side of the cutter 6 breaks off the capacitor lead 9, and the bending surface on the bottom right side of the cutter 6 presses the capacitor lead 9 into the bending groove 11 to achieve bending. Then, the cylinder 3 drives the upper mold 2 to move upwards, and the spring 13 returns, causing the pressure plate 5 to pop down from the slide 12 back to its initial position.
