Description

TECHNICAL FIELD

[0001] The application belongs to the field of capacitors, and particularly relates to a machine-inserted lying-down type outward-bent capacitor pin forming device. BACKGROUND

[0002] Two conductors close to each other with an insulating medium in between constitute a capacitor. When a voltage is applied between the two plates of the capacitor, the capacitor will store electric charge.

[0003] When a conventional lying-down type outward-bent capacitor is installed, it is usually inserted into a circuit board by manual insertion and then welded, and after welding, it is manually pushed down to form a lying-down type. In order to improve the installation efficiency of the capacitor, the capacitor can also be inserted into the circuit board by machine automatic insertion, and the pin is bent automatically at the same time, and then welded to form a lying-down type. The outward-bent capacitor installed by machine automatic insertion has different requirements for the pin compared with the outward-bent capacitor installed by manual insertion. The outward-bent capacitor installed by machine automatic insertion needs to reserve a larger bending space between the bending part of the pin and the capacitor body in order to facilitate machine bending.

[0004] The existing capacitor pin forming device only has the function of bending the pin, and the function is single, and the bent pin is not conducive to machine bending. SUMMARY

[0005] The application aims to provide a machine-inserted lying-down type outward-bent capacitor pin forming device which can bend and form the capacitor pin and stretch and extrude the pin at the same time, so as to reduce the thickness of the pin and facilitate machine automatic insertion and bending.

[0006] In order to achieve the above-mentioned purpose, the application adopts the following technical scheme: a machine-inserted lying-down type outward-bent capacitor pin forming device, comprising a mold core support, a mold core and a swing block, the back of the mold core support is connected with a first driving device, the mold core is fixedly installed on the mold core support, symmetrical forming blocks are arranged on both sides of the mold core, an inclined forming surface is arranged on the forming block, an inclined guide surface is arranged on the end of the mold core, two swing blocks are symmetrically arranged on both sides of the mold core, a positioning groove is arranged on the end face of the swing block, the pin of the capacitor is placed in the positioning groove, the side surface of the pin extends out of the end face, the distance between the two swing blocks is greater than or equal to the thickness of the mold core, and a avoiding groove corresponding to the forming block is further arranged on the end face.

[0007] Further description of the above technical scheme is as follows:

[0008] The distance between the two swing blocks is equal to the thickness of the mold core.

[0009] Further description of the above technical scheme is as follows:

[0010] The forming block is detachably installed on the mold core.

[0011] As the further description of the above technical solution:

[0012] The mold core is provided with a sliding groove, and the forming block is fixedly installed in the sliding groove.

[0013] As the further description of the above technical solution:

[0014] The end face is an arc face.

[0015] As the further description of the above technical solution:

[0016] The swing block is rotatably installed on the support seat, and one end of the swing block is connected to the second driving device through a connecting block.

[0017] As the further description of the above technical solution:

[0018] The second driving device is an electric push rod, and the connecting block is pivotally connected to the push rod of the second driving device.

[0019] As described above, due to the adoption of the above technical solution, the beneficial effects of the present application are:

[0020] 1. In the present application, the capacitor pin is bent and formed while being extruded and stretched, reducing the thickness of the pin and facilitating automatic insertion of the machine. In addition, the mold core extrudes and stretches the pin, providing more bending space between the bent part of the pin and the capacitor body to facilitate machine bending.

[0021] 2. In the present application, the forming block slides in the sliding groove to adjust the position and is fixed by a screw. The forming block slides back and forth in the sliding groove, which can adjust the distance between the forming block and the swing block. In the case of a fixed forward movement distance of the mold core support, the forming effect of the forming block on the pin can be adjusted, and the degree of "outer bending" of the pin can be flexibly adjusted.

DETAILED DESCRIPTION

[0033] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0035] Please refer to Figures 1-8The application provides a technical scheme: a machine-inserted lying-down type outer-bending capacitor pin forming device, which comprises a mold core support 1, a mold core 2 and a swing block 3, the back of the mold core support 1 is connected with a first driving device, the mold core 2 is fixedly installed on the mold core support 1, symmetrical forming blocks 21 are arranged on the two sides of the mold core 2, inclined forming surfaces 211 are arranged on the forming blocks 21, an inclined guide surface 22 is arranged at the end of the mold core 2, two swing blocks 3 are symmetrically arranged on the two sides of the mold core 2, a positioning groove 311 is arranged on the end surface 31 of the swing block 3, the pin 41 of a capacitor 4 is placed in the positioning groove 311, the side surface of the pin 41 extends out of the end surface 31, the distance between the two swing blocks 3 is greater than or equal to the thickness of the mold core 2, and a avoiding groove 312 corresponding to the forming block 21 is further arranged on the end surface 31.

[0036] The distance between the two swing blocks 3 is equal to the thickness of the mold core 2, so that the mold core 2 can fully extrude the pin 41, the extrusion and stretching effect is improved, and the pin can be bent when the machine automatically inserts the component.

[0037] The forming block 21 is detachably installed on the mold core 2, the mold core 2 is provided with a sliding groove 23, and the forming block 21 is fixedly installed in the sliding groove 23. After the forming block 21 is adjusted in position in the sliding groove 23, the forming block 21 is fixed through screws. The forming block 21 can slide forward and backward in the sliding groove 23, the distance between the forming block 21 and the swing block 3 can be adjusted, the forming effect of the forming block 21 on the pin 41 can be adjusted under the condition that the mold core support 1 moves a fixed distance forward, and the degree of “outer bending” of the pin 41 can be flexibly adjusted.

[0038] The end surface 31 is an arc surface, and the significance lies in that when the swing block 3 rotates on the support seat 5, the end surface 21 of the swing block 3 is tangent to the mold core 2 (when the mold core 2 moves between the two swing blocks 3), so that the end surface 31 of the swing block 3 does not affect the movement of the mold core 2. For details, refer to the accompanying drawings. Figure 3 .

[0039] The swing block 3 is rotatably installed on the support seat 5, one end of the swing block 3 is connected with a second driving device 6 through a connecting block 32, and the rotation of the swing block 3 on the support seat 5 can adjust the distance between the two positioning grooves 311, so as to adjust the capacitor with different pin distances adapted to the two swing blocks 3. For details, refer to the accompanying drawings. Figure 3 .

[0040] The second driving device 6 is an electric push rod, the connecting block 32 is pivotally connected to a push rod 61 of the second driving device 6, and the rotation of the swing block 3 is realized through the forward and backward pushing of the push rod 61 in the electric push rod. The swing block 3 can keep the position stable by adopting the electric push rod to push, and the pin forming effect is guaranteed.

[0041] Working principle: When the lead 41 of capacitor 4 is bent and formed, the positions of the two swing blocks 3 remain unchanged. Capacitor 4 is held by the clamping device, and the lead 41 is placed in the positioning groove 311 of the swing block 3. Then, the mold core support 1 moves horizontally forward under the action of the first driving device (see Appendix). Figure 1 , 2 The guide surface 22 at the end of the mold core 2 on the mold core support 1 first contacts the side of the pin 41 (the part of the pin 41 that extends out of the end face 31). As the mold core 2 moves forward, it compresses and stretches the pin 41, reducing the pin thickness. Simultaneously, as the mold core 2 continues to move forward, the forming surface 211 of the forming block 21 contacts the pin 41, causing the pin 41 at the clearance groove 312 to form an "outwardly bent" structure. After forming, the mold core support 1 detaches from the pin 41. While bending and forming the capacitor pin, the mold core 2 also compresses and stretches the pin, reducing its thickness and facilitating bending during automatic insertion. Furthermore, the compression and stretching of the pin 41 by the mold core 2 allows for a larger bending space between the bent portion of the pin and the capacitor body, facilitating machine bending.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
