[0015] This invention provides a cold heading forming device for nuts. It has the following beneficial effects: I. This nut cold heading forming equipment, through its cold heading device design, includes a guiding mechanism for conveying nuts. This guiding mechanism ensures uniform conveying of the nuts while maintaining stability during the conveying process, limiting material movement to avoid affecting subsequent work efficiency. Then, a positioning mechanism clamps and fixes the nuts for easy subsequent unloading. A six-axis robotic arm controls a clamping mechanism to hold the positioned nuts, thus achieving the function of material handling. The six-axis robotic arm uses multi-angle rotation to place the material on top of the processing device, which then clamps and fixes the nuts. This process maintains material stability to meet subsequent operational needs. The composite device is then adapted to the processing device, which compresses the nut to punch its inner hole. After cold heading and punching, slight burrs remain; these are rubbed away by the composite device to reduce subsequent processing difficulty, thus achieving rough machining of the nut. After machining, a six-axis robotic arm controls a clamping mechanism to hold the nut for secondary handling. The nut is then placed inside a conveyor, which transports the material, ensuring the equipment can operate normally.

[0016] II. This nut cold heading forming equipment, through its clamping mechanism design, uses a clamping slider to control the clamping block to slide inside the clamping slide rail, thereby achieving the function of clamping materials. This facilitates subsequent material handling and increases the automation rate of the equipment. A silicone block is set on one side of the clamping block. The silicone block is made of silicone, which has a certain degree of wear resistance and cushioning effect, thereby reducing wear between parts, extending the service life of the equipment, reducing scratches on the material surface, and avoiding affecting product quality. By opening slits on the block surface, the surface texture of the parts is increased, thereby improving the surface friction performance of the parts and further improving the clamping effect. In addition, grooves are opened to provide a certain anti-slip effect and prevent derailment during clamping and handling.

[0017] Third, this nut cold heading forming equipment, through the design of the guiding mechanism, uses a conveyor belt to transport and move materials. During the nut transport process, the silicone pad adheres to the nut surface. The component is subjected to the reaction force of the material, causing the guide plate to drive the connecting rod to compress and contract the first spring, thereby playing a role in shock absorption and buffering, limiting the movement space of the material during transport, reducing vibration during transportation, improving the stability of the transport process, and avoiding affecting the subsequent clamping effect. This achieves the function of uniform and stable material transport. Secondly, the silicone pad provides a certain degree of protection for the components, reducing wear between components, thereby extending the service life of the equipment, and reducing rigid collisions between components.

[0018] IV. This nut cold heading forming equipment, through its processing device design, places the nut inside a circular groove. A hydraulic column pushes an arc-shaped block into the circular groove, thereby clamping the material and maintaining its stability. This prevents displacement during punching and avoids affecting subsequent work efficiency. A spherical block is placed on one side of the arc-shaped block to increase the surface texture of the component, further improving its surface friction performance and enhancing the clamping effect. Furthermore, the spherical block is made of plastic, providing a cushioning effect and reducing wear on the material surface, thus extending the equipment's service life. After punching, a pushing mechanism lifts the material for easy removal. A cleaning mechanism then removes debris generated during punching, preventing it from entering the equipment and affecting its operation.

[0019] V. This nut cold heading forming equipment, through a composite device design, uses a hydraulic rod to control components to extrude material into the processing device, thereby achieving the punching operation. This protects the equipment, reduces impact vibration, extends service life, absorbs instantaneous impact energy, reduces equipment resonance, protects the mold, prevents damage from hard contact of the punch, stabilizes metal flow, and improves hole wall quality. During the punching process, certain burrs exist on the inner surface of the nut hole. The motor controls the punching head to rub against the inner hole of the nut, thereby achieving a certain deburring effect. The burrs generated during cleaning are absorbed by a cleaning mechanism to reduce debris accumulation and avoid affecting the operation of components. The punching head can be installed and disassembled through an installation mechanism, facilitating component replacement and improving the operating efficiency of the equipment.

A guiding mechanism 15 is fixedly connected to one side of the top of the workbench 11, and a positioning mechanism 16 is fixedly connected to the side of the guiding mechanism 15. A conveyor 17 is fixedly connected to the side of the top of the workbench 11 away from the positioning mechanism 16. The guiding mechanism 15 is used to convey nuts, ensuring uniform conveying while maintaining stability during the conveying process and limiting the movement space of the material to avoid affecting the efficiency of subsequent operations. The positioning mechanism 16 then clamps and fixes the nuts for easy removal. The six-axis robotic arm 13 controls the clamping mechanism 14 to clamp the positioned nuts, thus achieving the function of material handling. The six-axis robotic arm 13 rotates at multiple angles to place the material on top of the processing device 2, where the processing device 2 clamps and fixes the nuts to maintain the stability of the material. The nut is then fixed to meet the requirements of subsequent operations. The composite device 3 is then adapted to the processing device 2. The composite device 3 compresses the nut to achieve the punching operation of the inner hole of the nut. After cold heading and punching, there are slight burrs. The composite device 3 rubs the burrs to reduce the difficulty of subsequent processing, thereby achieving rough processing of the nut. After processing, the nut is clamped by the clamping mechanism 14 controlled by the six-axis robotic arm 13. The nut is then transported a second time and placed inside the conveyor 17. The conveyor 17 transports the material to ensure the normal operation of the equipment.

[0024] The clamping mechanism 14 includes a clamping frame 141, a clamping slide rail 142 fixedly connected to the outer side of the clamping frame 141, a clamping slider 143 slidably connected to the inner side of the clamping slide rail 142, a clamping block 144 fixedly connected to the outer side of the clamping slider 143, a silicone block 145 fixedly connected to one side of the clamping block 144, and a block surface cutout 146 opened on the outer side of the silicone block 145 away from the clamping block 144. The clamp block 144 is controlled by the clamp slider 143 to slide inside the clamp slide rail 142, thereby clamping the material and facilitating subsequent material handling, thus increasing the automation rate of the equipment. A silicone block 145 is set on one side of the clamp block 144. The silicone block 145 is made of silicone, which has a certain wear resistance and cushioning effect, thereby reducing wear between parts, extending the service life of the equipment, reducing scratches on the material surface, and avoiding affecting product quality. By opening the block surface cut 146, the surface texture of the parts is increased, thereby improving the surface friction performance of the parts, further improving the clamping effect, and the groove provides a certain anti-slip effect to prevent derailment during clamping and handling.

The material is conveyed and moved by the conveyor belt 152. During the conveying of the nut, the silicone pad 156 is attached to the surface of the nut. The component is subjected to the reaction force of the material, which causes the guide plate 155 to drive the connecting rod 153 to squeeze and contract the first spring 154, thereby playing a role in shock absorption and buffering, limiting the movement space of the material during the conveying process, reducing the shaking during transportation, improving the stability of the conveying process, and avoiding affecting the subsequent clamping effect. This achieves the function of conveying the material at a uniform speed and stably. Secondly, the silicone pad 156 provides a certain protective effect for the component, reduces the wear between components, thereby extending the service life of the equipment and reducing rigid collisions between components.

[0026] The positioning mechanism 16 includes a positioning frame 161. A first electric push rod 162 is fixedly connected to the outer side of the positioning frame 161. A positioning plate 163 is fixedly connected to one side of the first electric push rod 162. A prismatic block 164 is fixedly connected to the outer side of the positioning plate 163 away from the first electric push rod 162. During the uniform conveying of materials, the first electric push rod 162 pushes the positioning plate 163 to clamp the materials, thereby fixing the materials and providing a certain pre-positioning effect. This facilitates the handling of materials by subsequent equipment, prevents deviation during subsequent handling, avoids affecting work efficiency, and improves the accuracy of material handling. The prismatic block 164 is made of rubber, which provides a buffering effect during the compression of materials, preventing excessive compression force from damaging components, and also provides a certain protective effect, improving the clamping effect.

A hydraulic column 24 is fixedly connected to the outer side of the square frame 23. An arc-shaped block 25 is fixedly connected to the outer side of the hydraulic column 24 away from the square frame 23. A spherical block 26 is fixedly connected to the outer side of the arc-shaped block 25 away from the hydraulic column 24. A pushing mechanism 27 is fixedly connected to the inner side of the processing frame 21. A cleaning mechanism 28 is fixedly connected to the outer side of the processing frame 21. The nut is placed inside the circular groove 22, and the arc-shaped block 25 is pushed into the circular groove 22 by the hydraulic column 24 to clamp the material, thereby maintaining the stability of the material and preventing displacement during punching, thus preventing the impact on subsequent operation efficiency. A spherical block 26 is set on one side of the arc-shaped block 25. The spherical block 26 increases the surface texture of the component, thereby further improving the surface friction performance of the component and enhancing the clamping effect of the component surface. Secondly, the spherical block 26 is made of plastic, which plays a certain role in buffering and reducing the wear of the component on the surface of the material, thereby extending the service life of the equipment. After punching, the material is lifted by the pushing mechanism 27 to facilitate the removal of the material. Then, the cleaning mechanism 28 cleans up the debris generated during the punching process to prevent the debris from entering the equipment and affecting the operation of the equipment.

[0028] The pushing mechanism 27 includes a second electric push rod 272, the bottom of which is fixedly connected to the bottom of the circular groove 22, and a push plate 271 is fixedly connected to the top of the second electric push rod 272.

A fan 282 is fixedly connected to one side of the cleaning housing 281, and a guide pipe 283 is fixedly connected to the other side of the cleaning housing 281 away from the fan 282. The fan 282 generates airflow, which draws in debris from the other side of the guide pipe 283, thereby cleaning debris from the surface of the components. This reduces the amount of debris entering the equipment, preventing increased wear during subsequent operation and extending the equipment's service life.

[0030] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 9 to 10As shown, the composite device 3 includes a hydraulic rod 31, a buffer mechanism 32 is fixedly connected to the bottom of the hydraulic rod 31, a column frame 33 is fixedly connected to the side of the buffer mechanism 32 away from the hydraulic rod 31, a motor 34 is fixedly connected to the inner side of the column frame 33, a rotating shaft 35 is fixedly connected to the bottom of the column frame 33, the output end of the motor 34 is fixedly connected to the outer side of the rotating shaft 35, and a mounting mechanism 36 is fixedly connected to the side of the rotating shaft 35 away from the motor 34. A punching head 37 is provided on the inner side of the mounting mechanism 36. The hydraulic rod 31 controls the components to press against the processing device 2, thereby achieving the punching operation of the material. This protects the equipment, reduces impact vibration, extends service life, absorbs instantaneous impact energy, reduces equipment resonance, protects the mold, avoids damage from hard contact of the punch, stabilizes metal flow, and improves the quality of the hole wall. During the punching process, there are certain burrs on the inner surface of the nut hole. The motor 34 controls the punching head 37 to rub against the inner hole of the nut, thereby achieving a certain deburring effect. The burrs generated during cleaning are absorbed by the cleaning mechanism 28 to reduce debris accumulation and avoid affecting the operation of the components. The punching head 37 is installed and removed by the installation mechanism 36, which facilitates component replacement and improves the operating efficiency of the equipment.

[0031] The buffer mechanism 32 includes a first circular plate 321, with a support rod 322 fixedly connected to the top of the first circular plate 321. A second circular plate 324 is slidably connected to the side of the support rod 322 away from the first circular plate 321. A second spring 323 is sleeved on the outer side of the support rod 322. When the bottom of the equipment contacts the surface of the material, the component is subjected to the reaction force of the material, causing the first circular plate 321 to drive the support rod 322 to compress and contract the second spring 323 towards the second circular plate 324. This serves to dampen and buffer the impact, protect the equipment, reduce impact vibration, extend service life, absorb instantaneous impact energy, reduce equipment resonance, protect the mold, prevent damage from hard contact of the punch, stabilize metal flow, and improve the quality of the hole wall.

[0032] The mounting mechanism 36 includes a mounting housing 361, an outer housing 362 fixedly connected to the outside of the mounting housing 361, and a third electric push rod 363 fixedly connected to the outside of the outer housing 362.

[0033] In use, the guiding mechanism 15 is used to convey nuts, ensuring uniform delivery while maintaining stability during the conveying process. This restricts the material's movement during transport, preventing disruption to subsequent operations. The positioning mechanism 16 then clamps and secures the nuts for easy removal. The six-axis robotic arm 13 controls the clamping mechanism 14 to hold the positioned nuts, thus achieving material handling. The six-axis robotic arm 13 rotates at multiple angles to place the material on top of the processing device 2, which then clamps and secures the nuts, maintaining stability and meeting subsequent operational requirements. The processing device 2 places the nuts in a circular groove 2. 2. Inside, a hydraulic column 24 pushes an arc-shaped block 25 towards a circular groove 22 to clamp the material, maintaining its stability and preventing displacement during punching, thus avoiding impact on subsequent work efficiency. A spherical block 26 is placed on one side of the arc-shaped block 25 to increase the surface texture of the component, further improving its surface friction and clamping effect. The spherical block 26 is made of plastic to provide cushioning, reducing wear on the material surface and extending the equipment's lifespan. After punching, a pushing mechanism 27 lifts the material for easy removal. Then, a cleaning mechanism 28 cleans the punched area. The debris generated during the process is cleaned to prevent it from entering the equipment and affecting its operation. Then, the composite device 3 is adapted to the processing device 2. The composite device 3 compresses the nut to achieve the punching operation of the nut's inner hole. After cold heading punching, there are slight burrs. The composite device 3 abrades these burrs to reduce the difficulty of subsequent processing, thus achieving rough machining of the nut. After machining the nut, the composite device 3 uses the hydraulic rod 31 to control the component to compress it against the processing device 2 to achieve the punching operation of the material. This process protects the equipment, reduces impact vibration, extends service life, absorbs instantaneous impact energy, reduces equipment resonance, and protects the mold by preventing hard contact of the punch. Damage, stabilizing metal flow, and improving hole wall quality: During the punching process, there are certain burrs on the inner surface of the nut hole. Then, the punching head 37 controlled by the motor 34 rubs the inner hole of the nut to achieve a certain deburring effect. The burrs generated during cleaning are absorbed by the cleaning mechanism 28 to reduce debris accumulation and avoid affecting the operation of the parts. The punching head 37 is installed and disassembled by the installation mechanism 36 to facilitate the replacement of parts and improve the operating efficiency of the equipment. The clamping mechanism 14 controlled by the six-axis robotic arm 13 clamps the nut and performs secondary handling of the nut. The nut is placed inside the conveyor 17, and the material is transported by the conveyor 17 to maintain the normal operation of the equipment.
