[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0024] See attached Figures 1 to 5 As shown, a pin forming bending angle tooling in this embodiment includes a bending component 3 and a forming fixed die component 4 corresponding to the position thereof; the bending component 3 includes a forming pressure block 32, and the forming fixed die component 4 includes a forming die 44. The bending surface 321 on the forming pressure block 32 matches the forming die 44 and can press and bend the pin on the forming die 44. The forming fixed die component 4 is also provided with an angle rebound adjustment component 6.

[0025] The bending component 3 cooperates with the forming mold component 4 to automatically bend the pins. The angle rebound adjustment component 6 can adjust the angle of the pins on the electronic product to be bent when placed on the forming mold component 4 according to the rebound height of the pins, so as to ensure that there will be no inclination after the pins are pressed and bent.

[0026] It should be noted that the forming block 32 and the shaping die 44 are arranged according to the required shape of the pin, and the specific shape is not limited, as long as the pin can be bent into the required shape after being pressed between the forming block 32 and the shaping die 44 .

[0027] In some embodiments, see Appendix Figure 4 and 5 The bending surface 321 of the forming block 32 is stepped, and the molding die 44 is also arranged in a corresponding stepped shape. After the forming block 32 presses and bends the pin on the molding die 44, a section of the formed pin away from the electronic product is parallel to the upper surface of the electronic product.

[0028] The angle rebound adjustment component includes an adjustment screw 61 threadedly connected to the upper surface of the molding fixed die component 4, and the adjustment screw 61 is arranged near the molding block 32. The height of the adjustment screw 61 embedded in the molding fixed die component 4 is adjusted by turning the adjustment screw 61 forward or backward to avoid the pin rebounding and causing an inclination. The height of the adjustment screw 61 protruding from the molding fixed die component 4 is set according to the rebound height of the pin.

[0029] In some embodiments, two angle rebound adjustment components are provided, and are respectively located on two product support parts 45 on the forming fixed mold component 4. After the electronic product is placed, the adjustment screw 61 can just press against the side edge of the electronic product close to the bending component 3 from the lower surface.

[0030] It should be noted that the angle rebound adjustment component is not limited to the adjustment screw 61, and can also be a combination of a screw rod and a drive motor threadedly connected to the product support part 45, or a movable rod that can vertically penetrate the product support part 45 and whose height can be adjusted up and down, or other existing adjustment structures. The movement here can also be driven up and down by a cylinder, or driven up and down by a linear module.

[0031] The bending assembly 3 further includes a bending driving member 31, which is a horizontally arranged driving cylinder, and the forming block 32 is connected to the driving cylinder via a block connecting block 33. In some embodiments, the bending driving member is not limited to being a driving cylinder, as long as it can drive the forming block to move toward the forming fixed die assembly.

[0032] The forming press block 32 is detachably connected to the press block connecting block 33. The corresponding forming press block 32 can be replaced according to the required pins of different bending shapes, thereby improving the applicability of the tooling. The forming press block 32 can be connected to the press block connecting block 33 by screws, or can be clamped with the press block connecting block 33 to achieve quick disassembly and replacement.

[0033] The bottom of the pressing block connecting block 33 is connected to the tooling bracket 2 through a guide rail 34, and the guide rail 34 is arranged in a direction close to the forming fixed die assembly 4. By setting the guide rail 34, it is possible to provide a guide for the movement of the forming pressing block 32 toward the forming fixed die assembly 4, thereby ensuring the efficiency and quality of the bending of the pins by the forming pressing block 32.

[0034] The molding block 32 further includes a limiting surface 322 provided on the protruding bending surface 321. The limiting surface 322 is provided in a rack shape along its length direction, and a limited space for the pin to be placed is left between two adjacent racks. The spacing between two adjacent racks on the limiting surface 322 is set according to the width of the pin. The setting of the limiting surface 322 protruding from the bending surface 321 can ensure that when the molding block 32 is pressed against the pin, the limiting surface 322 first contacts the pin, thereby ensuring that the pin will not be misaligned during the subsequent pressing and bending, thereby ensuring the processing quality of the electronic product.

[0035] The molding fixed mold assembly 4 also includes a molding fixed mold body, on which a product positioning groove 42 and a pin placement groove 43 are opened along its height direction. The product positioning groove 42 and the pin placement groove 43 are separated by a product support portion 45, and the molding mold 44 is arranged close to the pin placement groove 43.

[0036] The product positioning groove 42 and the product support part 45 are both symmetrically arranged along the center line of the length direction of the molding fixed mold body. The product positioning groove 42 is used to limit the two sides of the electronic product placed on the support part, and the pin placement groove 43 is used to accommodate the pins on the electronic product after the limit, so as to realize the position limitation of the electronic product.

[0037] The product positioning groove 42 and the pin placement groove 43 are both open on one side near the bending component 3, and a plurality of stoppers 41 are provided on the molding fixed mold body. The openings on one side of the product positioning groove 42 and the pin placement groove 43 can avoid interference when the molding block 32 presses against the pin, thereby ensuring the bending efficiency of the pin. The plurality of stoppers 41 can limit the position of the electronic product placed on the molding fixed mold body, thereby avoiding positional deviation when the pins thereon are subsequently bent, thereby affecting the bending effect.

[0038] A protective cover 1 is disposed outside the bending assembly 3 and the forming fixed die assembly 4. The protective cover 1 can prevent dust from accumulating on the bending assembly 3 and the forming fixed die assembly 4, and there is no need to clean it frequently.

[0039] The forming fixed die body is connected to the tooling bracket 2 via the fixed die support frame 5 .

[0040] Working principle:

[0041] Before bending the pins of the electronic product, the height of the adjusting screw 61 embedded in the product support part 45 is adjusted according to the rebound height of the metal pin, so as to adjust the placement angle of the electronic product on the forming fixed mold assembly 4 to avoid the inclination problem caused by the subsequent rebound of the bent pin.

[0042] Subsequently, the electronic product whose pins need to be bent is placed on the forming mold assembly 4. The product support portion 45 on the forming mold assembly 4 supports the electronic product. At the same time, the product positioning groove 42 cooperates with the limit member 41 to position the entire electronic product. After positioning, the pins of the electronic product are just in the pin placement groove 43.

[0043] Finally, the bending drive 31 starts to work, driving the forming block 32 to move along the guide rail 34 until the forming block 32 presses the pins of the electronic product onto the shaping die 44, and bends the pins into a desired shape according to the shapes of the forming block 32 and the shaping die 44.

[0044] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
