[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-6 As shown, it illustrates a multi-station cold heading machine for screw production in one embodiment of the present invention, including: a support member 1, a square groove 2 inside the support member 1, an ejector assembly 3 installed inside the square groove 2, a pressing assembly 6 installed at the top of the support member 1, a fixing block 4 fixedly connected at the center of the top of the support member 1, and a first module 5 snapped into the fixing block 4. The support member 1 has a through groove 7 at its top, and a feeding assembly 8 is installed inside the through groove 7.

[0024] For example, such as Figure 5 As shown, the feeding assembly 8 includes an electric push rod 81. The electric push rod 81 is fixedly connected to the bottom wall of the inner cavity of the through groove 7. The top of the electric push rod 81 is fixedly connected to a third support plate 82. The top of the third support plate 82 is fixedly connected to a linear guide rail 83. A linear slider 84 is slidably connected to the linear guide rail 83. A fixed frame 85 is fixedly connected to the top of the linear slider 84. A slide rail 86 is fixedly connected to the top of the inner cavity of the fixed frame 85. A sliding block 87 is slidably connected to the slide rail 86. A spring 88 is fixedly connected to the left wall of the inner cavity of the fixed frame 85. The end of the spring 88 is fixedly connected to the left end of the sliding block 87. A fixed rod 9 is fixedly connected to the rear end of the sliding block 87. A positioning ring 10 is fixedly connected to the bottom end of the fixed rod 9. A moving block 11 is fixedly connected to the front end of the sliding block 87. A positioning block 12 is fixedly connected to the rear end of the inner wall of the support frame 61 and to the front of the moving block 11. A semi-cylindrical groove is opened on the fixed rod 9. The first module 5 corresponds to the position of the groove.

[0025] In some examples, the purpose of the feeding assembly 8 is to feed and unload screws. After the feeding assembly 8 clamps the raw material, it operates, and the PLC controller controls the linear slider 84 to move under the constraint of the linear guide rail 83. The linear slider 84 drives the leftmost positioning ring 10 to move above the rightmost module 5. The linear guide rail 83 is a CKD LCR-8. The -20 model helps improve the efficiency, miniaturization, and energy saving of the device, reduces the weight of the moving parts, makes starting easier, and ensures the stability and precision of the movement, thereby achieving flexible start-up and operation. The output end of the electric actuator 81 moves down, causing the fixed frame 85 to move down via the guide rail and slider. The electric actuator 81 is an H-Track electro-hydraulic actuator model, which adopts a hydrodynamic design and can provide high load capacity. The fixed frame 85 causes the fixed rod 9 to move down via the sliding block 87. During the downward movement, the sliding block 87 drives the moving block 11 to contact the first positioning block 12. As the moving block 11 moves down, it causes the sliding block 87 to slide to both sides on the slide rail 86. At the same time, the sliding block 87 drives the fixed rod 9 to slide to both sides, thus determining and adjusting the opening of the fixed rod 9. The material is fed into module 5. The fixing rod 9 moves down with the sliding block 87 to both sides of the fixing block 4 to prevent obstruction of the normal operation of the pressing component 4. After the pressing component 4 and the ejecting component 3 work, the output end of the electric push rod 81 moves the spring 88 upward to push the sliding block 87 to move inward and clamp the material with the fixing rod 9 and the positioning ring 10. The springs 88 on the sliding block 87 are all made of chrome vanadium steel springs 88. The addition of vanadium element refines the structure of the steel, resulting in high strength and toughness, good fatigue resistance and impact resistance, and high stability. After the initial processing by the rightmost module, the linear guide rail 83 drives the linear slider 84 to move the positioning rod 9 to the top of the next set of module 5. The repeated operation allows the material to be cold-pressed step by step.

[0026] For example, such as Figure 3 As shown, the ejector assembly 3 includes a cylinder 31. The cylinder 31 is fixedly connected to the bottom wall of the inner cavity of the square groove 2. A first support plate 32 is fixedly connected to the output end of the cylinder 31. An ejector pin 33 is fixedly connected to the top of the first support plate 32. A slide rod 34 is fixedly connected to the top of the inner cavity of the square groove 2. The slide rod 34 is slidably connected to the inside of the first support plate 32. The top of the ejector pin 33 extends into the inside of the first module 5.

[0027] In some examples, the purpose of setting up the ejection component 3 is to smoothly eject the screw material after cold pressing, so as to facilitate the clamping and movement of the feeding component 3. After the pressing component 6 finishes working, the ejection component 3 starts working. The PLC controller starts the cylinder 31 to drive the first support plate 32 to slide under the limitation of the slide rod 34. The top of the ejector pin 33 is located inside the first module 5. As the first support plate 32 moves, the ejector pin 33 drives the material to move upward. After being released from the first module 5, it moves to the corresponding position under the support of the ejector pin 33. The cylinder 31 is an MPE series, which is a threaded needle type single-acting cylinder 31. It uses imported seals and is suitable for high-precision operation. It can provide high precision for the ejection of the ejector pin 33. After the feeding component 8 clamps it, the cylinder 31 retracts and the ejector pin 33 moves downward to facilitate the next ejection and improve the feeding efficiency.

[0028] For example, such as Figure 3 As shown, the pressing component 6 includes a support frame 61. The support frame 61 is fixedly connected to the top of the support member 1. A hydraulic cylinder 62 is fixedly connected to the top wall of the inner cavity of the support frame 61. A second support plate 63 is fixedly connected to the bottom of the hydraulic cylinder 62. A fixing ring 64 is fixedly connected to the bottom of the second support plate 63. A second module 65 is snapped into the inside of the fixing ring 64. The positions of the first module 5 and the second module 65 correspond one-to-one.

[0029] In some examples, the purpose of setting up the pressing component 6 is to cooperate between module 5 and module 65 to cold press the raw material step by step, gradually changing the shape of the raw material. By applying pressure in multiple small increments, the shape of the screw can be controlled more precisely, resulting in smaller dimensional errors in the finished product. After the material is loaded, the pressing component 6 works, and the PLC controller starts the hydraulic cylinder 62 to move the second support plate 63 downward. The second support plate 63 drives the fixing ring 64 to move the second module 65 downward. By applying pressure to the second module 65, it cooperates with module 5 to cold press the raw material. Multiple screw materials can be cold pressed at one time, improving production efficiency.

[0030] For example, such as Figure 4 As shown, a base plate 13 is fixedly connected to the left end of the support member 1, a collection box 14 is provided at the top of the base plate 13, a fixing plate 15 is fixedly connected to the top of the support member 1 and located on the left side of the support frame 61, and a second positioning block 16 is fixedly connected to the rear end of the fixing plate 15. The first positioning block 12 and the second positioning block 16 have the same shape.

[0031] In some examples, the purpose of setting a second positioning block 16 is to unload the formed screw. The distance between the second positioning block 16 and the leftmost first positioning block 12 is equal to the distance between the first positioning block 12. This allows the raw material to be clamped after the last cold pressing. As the feeding component 8 moves again, the next batch of raw material is cold pressed. After forming, the screw is separated from the fixing rod 9 by the cooperation between the second positioning block 16 and the moving block 11, and the internal screw falls into the collection box 14. Automated collection can reduce manpower, reduce costs, and effectively improve collection efficiency.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
