Detailed Implementation

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0026] The following is in conjunction with the appendix Figure 2-3 This application will be described in further detail.

[0027] refer to Figure 2 The electronic component shearing and bending device shown includes: a base 1 and a forming mechanism. A lower mold 2 is provided on the base 1. A tube groove 21 is provided at the top of the lower mold 2. A pin groove 22 is provided on both sides of the tube groove 21. The horizontal height of the bottom of the pin groove 22 is lower than the horizontal height of the bottom of the tube groove 21. A shearing platform 23 is provided on the side of the lower mold 2 where the two pin grooves 22 are far apart from each other.

[0028] The forming mechanism includes a mounting frame 3, a driving component, and an upper mold 5. The upper mold 5 is mounted on the mounting frame 3. The driving component is used to drive the upper mold 5 to move up and down. The upper mold 5 is located directly above the lower mold 2. The bottom of the upper mold 5 is provided with a pressure head 51 that is compatible with the tube groove 21. The upper mold 5 is provided with a lower pressing platform 52 that is compatible with the pin groove 22 on both sides of the pressure head 51. A cutter 53 is provided on the side of the bottom of the two lower pressing platforms 52 that are far apart from each other.

[0029] Based on the above structure, during use, the TVS tube to be processed is placed on the lower mold 2, and the main body of the TVS tube is placed in the tube groove 21 (so that the main body of the TVS tube is not subjected to vertical pressure). The pins on both sides of the main body of the TVS tube are placed on the shearing platform 23. Then, the driving component drives the upper mold 5 to move downward, so that the pressure head 51 presses on the pins on both sides of the main body of the TVS tube to fix the TVS tube. As the upper mold 5 continues to press down, the cutter 53 contacts the pins and cuts the pins. Then, the shearing platform 23 presses on the pins that have not been cut off. As the shearing platform 23 and the cutter 53 enter the pin groove 22, the pins are bent towards the pin groove 22, so that the cut TVS tube is U-shaped, completing the processing of the TVS tube. Only one processing is needed to complete the cutting and bending of the TVS tube pins, which is convenient, fast and improves processing efficiency.

[0030] like Figure 2 As shown, a fixed platform 24 is provided between the pin slot 22 and the tube slot 21. The horizontal height of the fixed platform 24 is higher than the horizontal height of the bottom of the tube slot 21. In this way, during processing, the TVS tube body is placed in the tube slot, and the pins of the TVS tube are supported by the fixed platform 24 and the shearing platform 23. When the pressure head 51 moves downward, it will press on the fixed platform 24, forming a clamping of the pins with the fixed platform 24.

[0031] like Figure 2 As shown, the upper mold 5 is provided with a sliding hole 54 extending upward from the bottom end of the upper mold 5, and the pressure head 51 is slidably disposed in the sliding hole 54; the top end of the pressure head 51 is provided with a first spring 55, so that when the upper mold 5 moves downward, the elastic force of the first spring 55 will cause the pressure head 51 to press on the fixed platform 24 first, and then perform subsequent shearing and bending.

[0032] like Figure 3 As shown, in order to guide the movement of the cutter 53, guide blocks 25 are provided at the top of both shearing platforms 23. The two guide blocks 25 extend from the bottom to the side away from each other on the side that is close to each other, so that the two guide blocks 25 form a funnel-shaped opening, which guides the movement of the cutter 53 and ensures that the cutter 53 enters the pin slot 22 after cutting the pin.

[0033] like Figure 2 As shown, a sleeve 31 is provided on the mounting bracket 3, and a slide rod 4 is slidably arranged inside the sleeve 31. The upper mold 5 is set at the bottom end of the slide rod 4. The movement of the slide rod 4 is guided by the sleeve 31. The driving component includes a gear and a handle 6. The gear is set inside the sleeve 31, and a rack 41 is provided on the vertical side of the slide rod 4. The gear meshes with the rack 41. The handle 6 is set on the outside of the sleeve 31 and is connected to one end of the gear. Rotating the handle 6 causes the gear to rotate, thereby causing the slide rod 4 to rise or fall, thus controlling the movement of the upper mold 5.

[0034] like Figure 2 As shown, a support frame 7 is provided on the mounting frame 3. One end of the support frame 7 extends directly above the slide rod 4. A reset assembly is provided between the slide rod 4 and the support frame 7 directly above it. The reset assembly includes a second spring 8. The two ends of the second spring 8 are connected to the support frame 7 and the slide rod 4 respectively. When the upper mold 5 moves downward, the second spring 8 is stretched. When no external force is applied to the throttle 6, the tension of the second spring 8 causes the slide rod 4 to move upward, thus resetting the upper mold 5.

[0035] like Figure 2 As shown, a mounting rod 9 is vertically mounted on the base 1, and the mounting bracket 3 is slidably sleeved on the mounting rod 9, so that the position of the mounting bracket 3 on the mounting rod 9 can be adjusted, thereby adjusting the stroke of the upper mold 5.

[0036] In summary, during use, the TVS tube to be processed is placed on the lower mold 2, and the main body of the TVS tube is placed in the tube groove 21. The pins on both sides of the main body of the TVS tube are placed on the shearing platform 23. Then, the driving component drives the upper mold 5 to move downward, so that the pressure head 51 presses on the pins on both sides of the main body of the TVS tube to fix the TVS tube. As the upper mold 5 continues to press down, the cutter 53 contacts the pins and cuts the pins. Then, the shearing platform 23 presses on the pins that have not been cut off. As the shearing platform 23 and the cutter 53 enter the pin groove 22, the pins are bent towards the pin groove 22, so that the cut TVS tube is U-shaped, completing the processing of the TVS tube. Only one processing is needed to complete the cutting and bending of the TVS tube pins, which is convenient, fast and improves processing efficiency.

[0037] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
