Description

Technical Field

[0001] The utility model relates to the technical field of metal processing equipment, in particular to an anti-vibration cold heading device for processing stainless steel screws. Background Art

[0002] Cold heading equipment, typically referring to cold heading machines and their associated supporting equipment, is a specialized piece of machinery used for cold heading. Cold heading is a machining process that utilizes the plastic deformation of metal under external forces, redistributing and shifting the metal's volume through a die, thereby forming the desired part or blank. This process is primarily used to produce standard fasteners such as bolts, screws, nuts, and rivets, as well as other parts requiring plastic forming of metal.

[0003] The functions of the cold heading device mainly include: Metal plastic forming: The cold heading device applies pressure to the metal through the mold, causing the metal to undergo plastic deformation at room temperature, thereby obtaining parts of the desired shape and size. Improve part quality: During the cold heading process, the cold work hardening of the metal improves the strength, hardness and wear resistance of the parts. At the same time, since the cold heading process can accurately control the size and shape of the parts, the parts produced have higher dimensional accuracy and surface quality. Realize automated production: Modern cold heading devices are mostly equipped with automation functions, which can realize continuous, multi-station, automated production processes. This not only improves production efficiency, but also reduces labor intensity and improves production safety.

[0004] However, in actual use, stainless steel screws are widely used in various industries due to their excellent corrosion resistance and aesthetics. However, the cold heading process of stainless steel often generates large impact forces and vibrations due to its high hardness and toughness. This not only affects the stability and service life of the equipment, but can also lead to reduced product precision and damaged surface quality. Utility Model Content

Stainless steel screws are widely used in various industries due to their excellent corrosion resistance and aesthetics. However, during the cold heading process of stainless steel, due to its high hardness and toughness, it often generates large impact forces and vibrations, which not only affects the stability and service life of the equipment, but can also lead to reduced product precision and damaged surface quality.

[0007] A U-shaped support frame is fixedly installed at the bottom of the front and rear ends of the cold heading machine body, and a transmission screw is rotatably connected to the middle part of the lower end of the U-shaped support frame through a rotating shaft. A driving motor is fixedly installed on the lower bottom end support of the cold heading machine body, and a first pulley is fixedly installed on the transmission shaft part at the front end of the driving motor. The outer end of the first pulley is connected to the second pulley through a belt transmission, and a transmission long shaft is fixedly installed in the middle of the second pulley. The outer curved surfaces of the front and rear ends of the transmission long shaft are respectively fixedly installed with first bevel gears, and the outer side of the first bevel gear is meshed with the second bevel gear.

[0008] Preferably, there are four supporting legs, which are symmetrically distributed at the four corners of the lower end of the cold heading machine body.

[0009] Preferably, the U-shaped support arms are symmetrically distributed on both sides of the lower end of the mounting top plate.

[0010] Preferably, the upper end of the buffer spring is fixedly mounted on the inner side of the upper annular limiting groove.

[0011] Preferably, there are two U-shaped support frames, which are symmetrically distributed at the bottom of the front and rear ends of the cold heading machine body.

[0012] Preferably, the transmission shaft is rotatably connected to the bottom of the cold heading machine body through a bearing seat support, and there are two first bevel gears, which are symmetrically distributed on the outer curved surfaces of the front and rear ends of the transmission shaft.

[0014] Preferably, the supporting rollers are symmetrically distributed on both sides of the lower end of the connecting plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] When the cam is in a state of being moved up and down by the spring, the spring is compressed or stretched upwards, and the friction force generated by the friction of the cam moving up and down along the inner wall of the limit straight slide groove is combined with the friction force generated by the friction of the cam moving up and down along the inner wall of the limit straight slide groove, which plays the role of absorbing and buffering the vibration generated by the stainless steel screw processing. At the same time, by rotating the limit nut, when the limit nut is rotated, the limit nut will move up and down due to the force generated by the threaded connection with the outer curved surface of the middle part of the adjusting screw. When the limit nut moves up and down, it will cooperate with the annular limit groove to release the buffer spring upward or compress it downward. When the buffer spring is released upward or compressed downward, the elastic potential energy of the buffer spring itself will increase or decrease accordingly, thereby achieving energy absorption and buffering of the vibration generated by the stainless steel screw processing. The initial elastic potential energy of the buffer spring can be adjusted to avoid the initial elastic potential energy of the buffer spring being too large or too small, which affects the effect of energy absorption and buffering.

[0017] 2. The utility model also releases the installation fixation of the mounting base plate by controlling to turn on the driving motor. When the driving motor is turned on, it will drive the transmission long shaft to rotate in sequence. When the transmission long shaft rotates, it will drive the first bevel gear to rotate. When the first bevel gear rotates, it will mesh and drive the second bevel gear to rotate. When the second bevel gear rotates, it will drive the transmission screw to rotate. When the transmission screw rotates, the force generated by the threaded connection between the connecting plate and the outer curved surface of the lower end of the transmission screw will drive the connecting plate to move linearly downward. When the connecting plate moves linearly downward, it will drive the supporting roller to move linearly downward and be supported on the ground. When the supporting roller moves linearly downward and is supported on the ground, it is convenient to push and move the cold heading machine body, thereby achieving energy absorption and buffering of the vibration generated by the stainless steel screw processing, and facilitating the movement and transfer of the cold heading machine body.

[0025] A U-shaped support frame 14 is fixedly installed at the bottom of the front and rear ends of the cold heading machine body 1, and there are two U-shaped support frames 14, which are symmetrically distributed at the bottom of the front and rear ends of the cold heading machine body 1. The middle part of the lower end of the U-shaped support frame 14 is rotatably connected to a transmission screw 15 through a rotating shaft. The lower bottom end support of the cold heading machine body 1 is fixedly installed with a drive motor 16. The front end transmission shaft part of the drive motor 16 is fixedly installed with a first pulley 17. The outer end of the first pulley 17 is connected to the second pulley 18 through a belt drive. A transmission long shaft 19 is fixedly installed in the middle of the second pulley 18, and the transmission long shaft 19 is rotatably connected to the bottom of the cold heading machine body 1 through a bearing seat. The outer curved surfaces of the front and rear ends of the transmission long shaft 19 are respectively fixed with first bevel gears 20 , and there are two first bevel gears 20, which are symmetrically distributed on the outer curved surfaces of the front and rear ends of the transmission long shaft 19.

[0026] Working principle: When in use, when the cold heading machine body 1 of the utility model processes stainless steel screws, the vibration generated by the stainless steel screw processing will be transmitted downward to the buffer spring 10. When the vibration generated by the stainless steel screw processing is transmitted downward to the buffer spring 10, the buffer spring 10 will be forced to compress downward or stretch upward to deform. When the buffer spring 10 is compressed downward or stretched upward, it will move up and down along the inner wall of the limiting straight slide groove 6 through the U-shaped support arm 4 synchronous belt damping block 5. When the damping block 5 moves up and down along the inner wall of the limiting straight slide groove 6, the elastic potential energy generated by the downward compression or upward stretching deformation of the buffer spring 10, combined with the friction force generated by the damping block 5 moving up and down along the inner wall of the limiting straight slide groove 6, will play a role in the stainless steel screw processing. The vibration generated is used to absorb and buffer the energy. At the same time, by rotating the limit nut 13, when the limit nut 13 is rotated, the limit nut 13 will move up and down due to the force generated by the threaded connection with the outer curved surface in the middle of the adjusting screw 11. When the limit nut 13 moves up and down, it will cooperate with the upper annular limit groove 12 to release the buffer spring 10 upward or compress it downward. When the buffer spring 10 is released upward or compressed downward, the elastic potential energy of the buffer spring 10 itself will increase or decrease accordingly, thereby achieving energy absorption and buffering of the vibration generated by the stainless steel screw processing. The initial elastic potential energy of the buffer spring 10 can be adjusted to avoid the initial elastic potential energy of the buffer spring 10 being too large or too small, which affects the effect of energy absorption and buffering.

[0027] At the same time, when the cold heading machine body 1 needs to be moved and transferred, the installation fixation of the mounting base 7 is released by releasing the bolts and the fixing holes 8. When the installation fixation of the mounting base 7 is released, the drive motor 16 is turned on by control. When the drive motor 16 is turned on, it will drive the first pulley 17 to rotate. When the first pulley 17 rotates, it will drive the second pulley 18 to rotate through the belt transmission. When the second pulley 18 rotates, it will drive the transmission shaft 19 to rotate. When the transmission shaft 19 rotates, it will drive the first bevel gear 20 to rotate. When the first bevel gear 20 rotates, it will engage and drive the second bevel gear 18 to rotate. The second bevel gear 21 rotates. When the second bevel gear 21 rotates, it drives the transmission screw 15 to rotate. When the transmission screw 15 rotates, the force generated by the threaded connection between the connecting plate 24 and the outer curved surface of the lower end of the transmission screw 15 drives the connecting plate 24 to move linearly downward. When the connecting plate 24 moves linearly downward, it drives the supporting roller 23 to move linearly downward and be supported on the ground. When the supporting roller 23 moves linearly downward and is supported on the ground, it is convenient to push and move the cold heading machine body 1, thereby achieving energy absorption and buffering of the vibration generated by the stainless steel screw processing, and facilitating the movement and transfer of the cold heading machine body 1.
