[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] In one embodiment, see Figure 1-Figure 3 , a device for quickly twisting the angle of a single-row pin, comprising a product positioning block 3 and a pressing block 6 that cooperate with each other, a connecting shaft 8 detachably connected to the pressing block 6, a product pre-stressing column 5 slidably connected to the middle of the pressing block 6, a pre-stressing spring 7 is arranged between the product pre-stressing column 5 and the connecting shaft 8, angle forming blocks 1 are slidably connected to both sides of the product positioning block 3, and a return spring 2 is arranged between the two angle forming blocks 1. A spring stopper 9 is arranged at the top of the product pre-stressing column 5, and a stud that cooperates with the spring stopper 9 is threadedly connected to the upper side of the product pre-stressing column 5. An angle forming block stopper 4 is arranged at the end of the angle forming block 1 away from the center of the product positioning block 3. An extrusion slope 11 is arranged on the surface where the pressing block 6 and the angle forming block 1 meet.
[0018] The two ends of the return spring 2 are respectively installed in the spring holes of the two angle forming blocks 1, and provide a return elastic force after the two angle forming blocks 1 are squeezed. The upper part of the product positioning block 3 is provided with a product positioning cavity to position the twisting foot assembly; a slide groove is provided in the middle, and two angle forming blocks 1 are installed. Two angle forming block stoppers 4 are installed on both sides and are connected and fixed with bolts 10. The two angle forming block stoppers 4 are respectively installed on both sides of the slide groove of the product positioning block 3, and are connected and fixed with bolts 10, which play a role in limiting the angle forming block 1. The product pre-compression column 5 is installed in the middle of the pressing block 6, which plays a role in pre-compression and fixing the twisting foot assembly to prevent the assembly from loosening when the foot is twisted. The pressing block 6 is above the device, and a pre-compression column is installed in the middle. Both sides are provided with inclined surfaces for inward extrusion. When moving downward, the twisting foot assembly is first pre-compressed and fixed, and then the inclined surface of the angle forming block 1 is squeezed, resulting in simultaneous inward movement of both sides to realize the plug-in twisting foot process. The pre-compression spring 7 is installed in the center hole of the connecting shaft 8, and is elastically connected to the product pre-compression column 5 to provide elastic force for product pre-compression. The lower part of the connecting shaft 8 is connected to the pressing block 6, a spring hole is arranged in the center, a pre-stressing spring 7 is installed, and a mold handle is arranged on the upper part to be fixed to the press. The spring stopper 9 is connected to the pre-stressing column bolt 10 to prevent the product pre-stressing column 5 from falling off from the pressing block 6.
[0019] How it works
[0020] The two angle forming blocks 1 are provided with an extrusion slope 11 and a twist foot angle forming slope, which are installed in the internal slide groove of the product positioning block 3. They produce horizontal inward movement under the extrusion of the slope of the pressing block 6, and the twist foot process is realized by extruding the plug pins through the twist foot slope. They are separated to both sides under the elastic force of the two return springs 2 and limited by the two angle forming block blocks 4.
[0021] During the implementation of this embodiment, with the help of external forces such as a punching machine, after the twisting foot assembly is placed in the product positioning block 3, the punching machine start switch is pressed to make the punching machine press downward, and the product pre-stressing column 5 of the upper die of the tooling first contacts the twisting foot assembly, and the twisting foot assembly is pressed into place by the elastic force of the pre-stressing spring 7, and then the pressing block 6 continues to press down, and the downward force is converted into a horizontal force F1 through the extrusion slope 11, pushing the two angle forming blocks 1 to move toward the middle, and the angle forming slope is used to squeeze the product pin into the required angle, and then the pressing block 6 rises, and the angle forming block 1 returns to its original position by the elastic force F2 of the internal return spring 2, completing a twisting foot.
[0022] The utility model is suitable for a device for quickly twisting the angle of a single-row pin, which greatly improves production efficiency and reduces labor costs. It clamps and completes the pin twisting in one go, which reduces the work intensity of operators and is more operator-friendly. It completely eliminates the problem of missing pin twisting in existing processes and improves quality stability.
