Description

Technical Field

[0001] The utility model relates to the technical field of bolt cold heading die forming equipment, in particular to a multi-station forming equipment of a bolt cold heading die. Background Art

[0002] Cold heading is a process that utilizes the plastic deformation of metal under external force and uses a die to redistribute and transfer the metal volume to form the required parts or blanks. Nowadays, cold heading is often used to produce standard fasteners such as bolts;

[0003] As shown in the reference case "A bolt cold heading die" announcement number "CN219004440U", the bolt cold heading die has almost no chance of outside air passing through the gap between the upper die and the lower die to affect the cold heading, thereby improving the precision of the bolts made after cold heading;

[0004] In the existing cold heading process, the mold is subjected to high-intensity impact and pressure, which will accelerate the wear of the mold and shorten its service life. Frequent wear and damage not only increases maintenance costs, but may also cause production interruptions and affect overall production efficiency.

[0005] Therefore, a multi-station forming device for a bolt cold heading die is proposed to solve the above problems. Utility Model Content

When the cold heading die is forming, the impact on the cold heading die can be buffered and protected by the protective component, thereby effectively extending the service life of the cold heading die.

[0008] Preferably, the protective component includes a movable plate arranged inside the mounting groove, the movable plate is located at the bottom of the cold heading die, and a plurality of buffer blocks are fixedly mounted on the surface of the movable plate, and the plurality of buffer blocks are equidistantly distributed. When the cold heading die is subjected to impact during forming, the plurality of buffer blocks on the top of the movable plate can absorb and disperse the vibration and impact force from the cold heading process, which not only protects the cold heading die, reduces wear and potential damage caused by impact, but also helps to maintain the stability and accuracy of the forming process.

[0009] Preferably, the buffer block is set in a semicircular shape, and multiple buffer blocks are in contact with the bottom of the cold heading die.

[0011] Preferably, a first spring is fixedly installed inside the first sealing tube, and both ends of the first spring are fixedly connected to the piston rod and the inner wall of the first sealing tube respectively. When the movable plate is impacted by the cold heading die during the forming process, the piston rod is pushed inward to compress the hydraulic oil in the first sealing tube and the first spring to help absorb the impact energy.

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.

[0023] When implementing: Figure 1-4 As shown, a multi-station forming device for a bolt cold heading die comprises: a base 1, hydraulic telescopic rods 2 are fixedly installed on both sides of the base 1, a cold heading die 21 is arranged on one side of the base 1, and the output ends of the two hydraulic telescopic rods 2 are fixedly installed with the same pressing die 22; a protective maintenance mechanism 3, which is used to protect the cold heading die 21 during forming, and is arranged on one side of the cold heading die 21; wherein the protective maintenance mechanism 3 comprises a mounting groove 31 opened on one side of the base 1, and the cold heading die 21 is provided on one side of the base 1. 1 is located inside the mounting groove 31, a protective component 32 is provided on one side of the mounting groove 31, and an inspection component 33 is provided on one side of the cold heading die 21. The cold heading die 21 is a multi-station bolt die, which can form multiple bolts at one time. When the cold heading die 21 is forming, the impact on the cold heading die 21 can be buffered and protected by the protective component 32, which effectively extends the service life of the cold heading die 21. At the same time, the inspection component 33 makes the cold heading die 21 easy to disassemble and inspect, which is very convenient.

[0024] like Figure 2 and Figure 3As shown, the protective component 32 includes a movable plate 321 arranged inside the mounting groove 31, the movable plate 321 is located at the bottom of the cold heading die 21, and a plurality of buffer blocks 322 are fixedly installed on the surface of the movable plate 321, and the plurality of buffer blocks 322 are equidistantly distributed. When the cold heading die 21 is impacted during forming, the plurality of buffer blocks 322 on the top of the movable plate 321 can absorb and disperse the vibration and impact force from the cold heading process, which not only protects the cold heading die 21, reduces the wear and potential damage caused by the impact, but also helps to maintain the stability and accuracy of the forming process. The buffer blocks 322 are arranged in a semicircular shape, and the plurality of buffer blocks 322 are in contact with the bottom of the cold heading die 21. The semicircular design enables the buffer blocks 322 to provide a wider contact surface, thereby enhancing the ability to absorb and disperse the impact force. This shape helps to achieve a more uniform pressure distribution, reduce the local pressure points on the bottom of the cold heading die 21, and thus reduce the risk of wear and damage.

The interior of the first sealing tube 323 is filled with hydraulic oil. When the cold heading die 21 is formed and impacted, the movable plate 321 receives these forces through the piston rod 324 at its bottom, and the piston rod 324 then transmits the force to the hydraulic oil therein. Through the compression of the hydraulic oil, the impact force generated during the cold heading process can be absorbed and buffered, thereby reducing the pressure directly acting on the cold heading die 21 and other parts of the equipment.

[0025] A first spring 325 is fixedly installed inside the first sealing tube 323, and the two ends of the first spring 325 are fixedly connected to the piston rod 324 and the inner wall of the first sealing tube 323 respectively. When the movable plate 321 is impacted by the cold heading die 21 during the forming process, the piston rod 324 pushes inward to compress the hydraulic oil in the first sealing tube 323 and the first spring 325 to help absorb the impact energy. After the impact force subsides, the rebound function of the first spring 325 makes the piston rod 324 return to the initial position to ensure that the movable plate 321 is ready to receive the next impact. A second sealing tube 326 is provided on one side of the first sealing tube 323, and the first sealing The tube 323 and the second sealing tube 326 are connected to each other through the delivery tube 327.

The punch pad 335 is fixedly connected to the fixed frame 331 and can be quickly connected to the corresponding connecting block 333 via two screws 334, so that the fixed frame 331 can fix the cold heading die 21. When the fixed frame 331 is in use, the connecting block 333 is connected to the inner wall of the connecting groove 332 via the third spring 336, so that the fixed frame 331 and the connecting block 333 can have a certain degree of freedom of movement when subjected to external force, thereby providing additional impact absorption. The setting of the buffer pad 335 effectively absorbs and disperses the vibration and impact force generated during production, thereby extending the service life of the fixed frame 331.

When the cold heading die 21 is forming and impacted, the movable plate 321 receives these forces through the piston rod 324 at its bottom, and the piston rod 324 then transmits the force to the hydraulic oil therein. Through the compression of the hydraulic oil, the impact force generated by the cold heading process can be absorbed and buffered, and the pressure directly acting on the cold heading die 21 and other parts of the equipment can be reduced. When the movable plate 321 is impacted during the forming process by the cold heading die 21, the piston rod 324 pushes inward to compress the hydraulic oil in the first sealing tube 323 and the first spring 325 to help absorb the impact energy. After the impact force subsides, the first spring The rebound function of the spring 325 returns the piston rod 324 to the initial position, ensuring that the movable plate 321 is ready to receive the next impact. The second sealing tube 326 is filled with hydraulic oil. When the hydraulic oil in the first sealing tube 323 is pressurized, the pressure is transmitted to the second sealing tube 326 through the delivery pipe 327, pushing the piston plate 328, and further compressing the second spring 329, helping to balance and disperse the impact force and reduce the pressure burden of a single component. It can be quickly connected with the corresponding connecting block 333 through two screws 334, so that the fixed frame 331 can fix the cold heading mold 21, and when the fixed frame 331 is in use, the connecting block 333 is connected to the inner wall of the connecting groove 332 through the third spring 336, so that the fixed frame 331 and the connecting block 333 can have a certain degree of freedom of movement when subjected to external force, providing additional impact absorption. The setting of the buffer pad 335 effectively absorbs and disperses the vibration and impact force generated in production, thereby extending the service life of the fixed frame 331.
