Description

Technical Field

[0001] This invention relates to the field of forming tooling technology, and in particular to a tooling for deforming the decorative legs of components. Background Technology

[0002] The electronic components required for the acquisition board include metal film resistors. Before use, the metal film resistors need to be bent and deformed according to fixed dimensions to form a flower-leg resistor that is compatible with the acquisition board. Each lead needs multiple bending angles, and the two leads need to be symmetrical.

[0003] The current forming process involves workers manually bending the resistor leads with flat-nose pliers. This requires multiple manual bending and bending operations to meet the required dimensions. This process is not only inefficient but also results in extremely poor consistency. Furthermore, the bending process can cause extra creases or scratches at the bent corners of the resistor, potentially leading to scrapping and additional losses. Summary of the Invention

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a component forming tooling, which can complete the forming of the forming by using a push-pull mechanism for pre-forming and then using a toggle mechanism for forming. It is convenient to operate and has high product consistency.

[0005] A tooling for deforming the leg of a component includes a mold base, a push-pull mechanism and a toggle mechanism. A template is installed on the surface of the mold base, and a slide is provided in the center of the template. The push-pull mechanism is slidably disposed in the slide. The template is provided with a pair of pre-forming blocks and a pair of forming sliders. When the push-pull mechanism enters the slide, it passes through the pre-forming blocks and the forming sliders in sequence. A pair of pre-formed blocks are respectively disposed on both sides of the slide rail, and the shape of the pre-formed block on the side closer to the slide rail matches the bend of the flower leg; a pair of forming sliders are respectively slidably disposed on both sides of the slide rail, and the shape of the forming slider on the side closer to the slide rail matches the concave angle of the flower leg; the actuating mechanism is movably connected to the side of the forming slider away from the slide rail, and when actuated, it squeezes the forming slider to slide closer to the slide rail; The head of the push-pull mechanism is provided with a resistor positioning groove. The resistor positioning groove, the pre-forming slider and the forming slider are located on the same plane and are higher than the mold base.

[0006] This transforming fixture replaces the traditional manual bending. It uses a push-pull mechanism for pre-forming and a toggle mechanism for final shaping to complete the leg deformation. It is easy to operate and produces products with high consistency.

[0007] Furthermore, the actuating mechanism includes a shift fork, a push block, and a locking block. The middle part of the shift fork is rotatably fixed to the template by a pin. The head of the shift fork is connected to one end of the push block, and the other end of the push block is connected to the locking block. The locking block is U-shaped, and the side of the forming slider away from the slide is arc-shaped. The inner sides of the two feet of the U-shaped locking block are provided with arc-shaped grooves that match the forming slider.

[0008] The tooling operation is made more convenient by setting up specific actuation mechanisms.

[0009] Furthermore, the actuating mechanism also includes a guide block and a pair of guide grooves. The guide block has a groove that matches the width of the push block, and both ends of the guide block are connected to the template. The pair of guide grooves are respectively located on both sides of the locking block. The inner side of the guide groove has a groove that matches the locking block, and the outer side is connected to the template.

[0010] By setting guide blocks and guide grooves, the push block and locking block can slide in the guiding direction, making the deformation tooling more precise.

[0011] Furthermore, the push block and the forming slider are provided with a strip-shaped through hole in the middle, and a spring is provided in the strip-shaped through hole. One end of the spring is connected to a spring limiting block, and the spring limiting block is connected to the template.

[0012] By incorporating a spring, the actuating mechanism automatically rebounds and resets after processing, making the processing operation more convenient.

[0013] Furthermore, a spring cover plate is provided at the strip-shaped through hole of the molding slider.

[0014] A spring cover is installed to prevent the spring from popping out when compressed.

[0015] Furthermore, it also includes a limiting pin and a limiting block. The limiting pin is located on the outer edge of the fork rotation when the resistor is in the forming position, and the limiting block is located at the front end of the push-pull mechanism when the resistor is in the forming position.

[0016] By setting limit pins and limit blocks, the displacement distance of the toggle mechanism and the push-pull mechanism is limited, so that the push-pull mechanism can accurately stop moving when the resistor reaches the forming position, which enhances product consistency and avoids bumps and unnecessary work caused by excessive rotation of the toggle fork.

[0017] Furthermore, the push-pull mechanism includes a push-pull slider, a push-pull handle, and a pressure block. The head of the push-pull slider is provided with a resistor positioning groove, the tail of the push-pull slider is connected to the push-pull handle, and the pressure block is rotatably connected to the push-pull slider, and the pressure block can be positioned above the resistor positioning groove.

[0018] By setting pressure blocks, the resistors can be pressed tightly to prevent displacement during molding, thus improving product consistency.

[0019] Furthermore, the pressure block is rotatably connected to the push-pull slider via an adjusting screw, and the adjusting screw is fitted with a spring.

[0020] By setting an adjusting screw and a spring, the screw height can be adjusted, thereby changing the pressure of the pressure block.

[0021] The beneficial effects of this invention are: The present invention provides a component forming tooling for deforming decorative legs. The tooling uses a push-pull mechanism for pre-forming and then a toggle mechanism for forming to complete the decorative leg deformation. This replaces the traditional manual bending, is easy to operate, and produces products with high consistency. At the same time, the overall mold occupies little space, is easy to move, and is flexible in operation. Attached Figure Description

[0024] To better explain and facilitate understanding of the present invention, it will be described in detail below with reference to the accompanying drawings and specific embodiments. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0025] like Figures 1-2 As shown, a component forming tooling includes a mold base 17, a push-pull mechanism and a toggle mechanism. A template 16 is installed on the surface of the mold base 17. A slide is provided in the center of the template 16. The push-pull mechanism is slidably disposed in the slide. The template 16 is provided with a pair of pre-forming blocks 14 and a pair of forming sliders 12. When the push-pull mechanism enters the slide, it passes through the pre-forming blocks 14 and the forming sliders 12 in sequence. A pair of pre-formed blocks 14 are respectively disposed on both sides of the slide rail. The shape of the pre-formed block 14 on the side closer to the slide rail matches the bend of the flower leg. A pair of forming sliders 12 are respectively slidably disposed on both sides of the slide rail. The shape of the forming slider 12 on the side closer to the slide rail matches the concave angle of the flower leg. The actuating mechanism is movably connected to the side of the forming slider 12 away from the slide rail. When actuated, the forming slider 12 is squeezed to slide closer to the slide rail. The head of the push-pull mechanism is provided with a resistor positioning groove. The resistor positioning groove, the pre-forming slider 12 and the forming slider 12 are located on the same plane and are higher than the mold base 17.

[0026] This transforming fixture replaces the traditional manual bending. It uses a push-pull mechanism for pre-forming and a toggle mechanism for final shaping to complete the leg deformation. It is easy to operate and produces products with high consistency.

[0027] More specifically, the template 16 is divided into two parts, left and right, which reduces the difficulty of processing and assembly.

[0028] Specifically, the actuating mechanism includes a shift fork 4, a push block 5, and a locking block 9. The middle part of the shift fork 4 is rotatably fixed to the template 16 via a pin 3. The head of the shift fork 4 is connected to one end of the push block 5, and the other end of the push block 5 is connected to the locking block 9. The locking block 9 is U-shaped, and the side of the forming slider 12 away from the slide is arc-shaped. The inner sides of the two feet of the U-shaped locking block 9 are provided with arc-shaped grooves that match the forming slider 12.

[0029] The tooling operation is made more convenient by setting up specific actuation mechanisms.

[0030] More specifically, the head of the shift fork 4 is rotatably connected to the push block 5 via a cylindrical pin 1, and when the shift fork 4 rotates, it causes the push block 5 to move.

[0031] Specifically, the actuating mechanism further includes a guide slider 7 and a pair of guide grooves 11. The guide slider 7 is provided with a groove that matches the width of the push block 5, and both ends of the guide slider 7 are connected to the template 16. The pair of guide grooves 11 are respectively provided on both sides of the locking block 9. The inner side of the guide groove 11 is provided with a groove that matches the locking block 9, and the outer side is connected to the template 16.

[0032] By setting the guide block 7 and the guide groove 11, the push block 5 and the locking block 9 can slide in the guiding direction, making the deformation tooling more precise.

[0033] Specifically, the middle part of the push block 5 and the forming slider 12 is provided with a strip-shaped through hole, and a spring 8 is provided in the strip-shaped through hole. One end of the spring 8 is connected to the spring limiting block 6, and the spring limiting block 6 is connected to the template 16.

[0034] By setting spring 8, the actuation mechanism can automatically spring back and reset after processing, making the processing operation more convenient.

[0035] Specifically, a spring cover plate 13 is provided at the strip-shaped through hole of the forming slider 12.

[0036] The spring cover plate 13 is provided to prevent the spring 8 from popping out when it is compressed.

[0037] Specifically, it also includes a limiting pin 2 and a limiting block 10. The limiting pin 2 is located on the outer edge of the fork 4 when the resistor 22 is in the forming position, and the limiting block 10 is located at the front end of the push-pull mechanism when the resistor 22 is in the forming position.

[0038] By setting limit pin 2 and limit block 10, the displacement distance of the toggle mechanism and the push-pull mechanism is limited, so that the push-pull mechanism can accurately stop moving when the resistor 22 reaches the forming position, which enhances product consistency and avoids bumps and unnecessary work caused by excessive rotation of the toggle fork 4.

[0039] Specifically, the push-pull mechanism includes a push-pull slider 15, a push-pull handle 20, and a pressure block 18. The head of the push-pull slider 15 is provided with a resistor positioning groove, and the tail of the push-pull slider 15 is connected to the push-pull handle 20. The pressure block 18 is rotatably connected to the push-pull slider 15 and can be positioned above the resistor 22 positioning groove.

[0040] By setting the pressure block 18, the resistor 22 can be pressed tightly to prevent displacement during molding and improve product consistency. The positioning groove of the resistor 22 is machined according to the maximum external dimensions of the resistor.

[0041] Specifically, the pressure block 18 is rotatably connected to the push-pull slider 15 via an adjusting screw 19, and the adjusting screw 19 is fitted with a spring 8.

[0042] By setting the adjusting screw 19 and the spring 8, the height of the screw can be adjusted, thereby changing the pressure of the pressure block 18.

[0043] Specifically, the mold base 17 is provided with a support leg 21 at its bottom. The support leg 21 supports the entire deformation tooling to a certain height, making it convenient for employees to operate.

[0044] The working process of a component leg deformation tooling is as follows.

[0045] Place resistor 22 into the resistor positioning slot of the push-pull slider 15, hold both ends of the pressure block 18 and lift it, rotating it until it presses down on resistor 22, making it firmly placed on the slider. At this time, resistor 22 is shaped like... Figure 3 As shown.

[0046] Hold the push-pull handle 20 and push the slider to move it along the slide rail at the center of the template 16 past the pre-forming position. At this time, the pin shape is pre-formed as shown. Figure 4 The U-shape shown.

[0047] Continue pushing the slider forward to the forming position of resistor 22, with the front end of the slider abutting against the limiting block 10. Manually operate the shift fork 4 assembly; the shift fork 4 rotates clockwise around the pin 3, causing relative movement between the groove at the front end of the shift fork 4 and the cylindrical pin 1 on the push block 5, driving the push block 5 forward. Simultaneously, the locking block 9 also moves forward. When the arc-shaped groove on the locking block 9 disengages from the left and right forming sliders 12, the straight surface of the locking block 9 exerts a lateral pushing force on the forming slider 12, pushing it towards the center and compressing the leads, completing the decorative deformation of resistor 22, resulting in a shape like... Figure 5 As shown.

[0048] After deformation is completed, the lever 4 is rotated counterclockwise by the lever and the spring 8, the locking block 9 returns to the initial position, and the forming slider 12 is reset by the elastic force of the spring 8 in the slider.

[0049] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make modifications, alterations, substitutions and variations to the above embodiments within the scope of the present invention.
