Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of bolts, and particularly relates to a bolt processing system. BACKGROUND

[0002] A bolt is a connecting piece commonly used by people to connect two objects, which is generally composed of a nut and a screw rod. In the manufacturing process of the bolt, the forming processing of the nut is a key link, which needs to be processed into a common hexagonal shape to facilitate use. At present, the processing of the nut is mainly carried out through the method of hot forging and pressing; the basic principle is to heat the nut end of the bolt blank to a certain temperature, so that it is softened and has good plasticity, and then the mold and forging and pressing equipment are used to process the required shape. However, in actual operation, hot forging and pressing processing still has some problems, which are as follows:

[0003] 1. Since the bolt blank needs to be heated to a certain temperature, the heated part will also react with oxygen in the air to form an oxide layer; if the oxide layer is not treated directly during hot forging and pressing forming, not only the processing quality of the bolt will be affected, but also the oxide layer slag will be left in the mold, affecting the subsequent processing; at present, before forging and pressing, workers generally hold metal rods to knock the surface of the bolt blank to remove the oxide layer. However, this cleaning method not only has poor cleaning effect, but also consumes a large amount of manpower and is low in efficiency;

[0004] 2. After hot forging and pressing is completed, the nut edge will produce a flash, in order to ensure the normal use of the bolt, the nut needs to be treated to remove the flash, at present, this process is usually carried out by workers using a flash removal device or handheld tools, this processing method is time-consuming and laborious, and also greatly reduces the production efficiency of the bolt.

[0040] The working steps and principles of the bolt processing system are as follows:

[0041] Step one, preparation work:

[0042] When it is needed to use the processing system to perform hot forging processing on the bolt blank 39, firstly, the bolt blank 39 to be processed end needs to be heated; when the temperature of the bolt blank 39 to be processed end reaches the required temperature, the preparation work is completed.

[0043] Step two, feeding:

[0044] After the preparation work is completed, the bolt blank 39 to be processed end is ensured to be upward, and is inserted into the lower die 2, so that the lower end of the bolt blank 39 is abutted against the lower oil cylinder 5, and the feeding is completed.

[0045] Step three, end surface oxide layer cleaning:

[0046] After the feeding is completed, the clamping cylinder 8 is controlled to be extended, and the lower end of the bolt blank 39 is clamped through the clamping block 7; then the switching motor 38 is started to drive the fourth bevel gear 37 to rotate in the positive direction, since the fourth bevel gear 37 and the third bevel gear 36 are engaged, and the third bevel gear 36 and the driving disc 22 are fixedly connected, the driving disc 22 is driven to rotate counterclockwise (the arrow direction shown in the figure) Figure 8As the rotating shaft 21 slides along the horizontal slide groove 20 and is also sliding within the inclined groove 23, it is driven to slide outward along the horizontal slide groove 20 under the action of the inclined groove 23. This causes the rotating wheel 28 to slide along the telescopic track 30. Since the two adjacent flipping plates 29 are pressed against the inner wall of the telescopic track 30, the rotating wheel 28 cannot rotate during the sliding process, thus preventing the hexagonal block 32 from rotating as it slides. As the driving disc 22 continues to rotate, it moves the rotating shaft 21 to the intersection of the inclined groove 23 and the arc-shaped groove 24. At this point, the rotating shaft 21 reaches its furthest position from the axis, causing the rotating wheel 28 to exit the telescopic track 30. This also causes the two adjacent flipping plates 29 and the limiting spring 31 to come into contact. Under the action of the limiting spring 31, The rotating wheel 28 does not rotate; as the drive disk 22 continues to rotate, when the rotating shaft 21 slides along the arc-shaped groove 24 of the disk, the rotating shaft 21 does not move because the arc-shaped groove 24 of the disk and the drive disk 22 are concentric. Since the pawl 26 is rotatably connected to the drive disk 22, the drive disk 22 drives the pawl 26 to rotate. When the pawl 26 touches the flip plate 29, the pawl 26 pushes the rotating wheel 28 to rotate against the limiting spring 31. As the drive disk 22 continues to rotate, when the rotating shaft 21 reaches the end of the arc-shaped groove 24 of the disk, the pawl 26 pushes the rotating wheel 28 to rotate exactly 60 degrees, so that the two adjacent flip plates 29 are again pressed against the limiting spring 30, and at the same time, the hexagonal block 32 is driven to rotate 60 degrees. Then the switching motor 38 is started to reverse, and the drive disk 22 is driven to rotate clockwise. Figure 8 (Middle), thus driving the pawl 26 to rotate. When the pawl 26 touches the flip plate 29, due to the high hardness of the limiting spring 31, the rotating wheel 28 is restricted from rotating, thus pushing the pawl 26 to overcome the torsion spring 27 and rotate, allowing the pawl 26 to pass over the flip plate 29; as the drive disc 22 rotates clockwise, when the rotating shaft 21 reaches the intersection of the disc inclined groove 23 and the disc arc groove 24, the switching motor 38 is driven to rotate clockwise again, thus driving the pawl 26 to push the rotating wheel 28 to rotate again. When the rotating shaft 21 reaches the end of the disc arc groove 24 again, the pawl 26 pushes the rotating wheel 28 to rotate 60 degrees again, driving the hexagonal block 32 to rotate 60 degrees, at which point the end face The scraper 34 rotates toward the axis; then the drive switching motor 38 reverses, and the transmission drive disk 22 rotates clockwise. Similarly, the pawl 26 is driven to pass over the flip plate 29. After the rotating shaft 21 passes the intersection of the disc inclined groove 23 and the disc arc groove 24, the drive disk 22 continues to rotate clockwise, driving the rotating shaft 21 into the disc inclined groove 23. The rotating shaft 21 is driven to slide along the horizontal slide groove 20 through the disc inclined groove 23, thereby driving the rotating wheel 28 back into the telescopic track 30. When the rotating shaft 21 reaches the end of the disc inclined groove 23, the rotating shaft 21 returns to the initial position, and the six hexagonal blocks 32 return to the initial position. At this time, the end face scraper 34 faces the axis and the top ends are aligned.

[0047] Then control the rotating motor 11 drive second bevel gear 10 rotation, because the first bevel gear 9 and second bevel gear 10 meshing, while the first bevel gear 9 and rotating disc 6 fixed connection, thus transmission rotating disc 6 rotation, because the clamping block 7 will bolt blank 39 clamping, thus drive bolt blank 39 follow rotation;Then control the main oil cylinder 4 stretch out, drive sliding plate 3 down sliding, thus drive lifting shell 18 down sliding, when end face scraper 34 lower side blade and bolt blank 39 upper end face contact, the main oil cylinder 4 continue to stretch out, make slide rod spring 15 compression, provide downward thrust, thus make end face scraper 34 can on bolt blank 39 upper end face on the oxidation impurities to scrape, complete end face oxide layer cleaning work.

[0048] Step four, circumference oxide layer cleaning:

[0049] When complete end face oxide layer cleaning work, control the main oil cylinder 4 shrink, drive sliding plate 3 upward movement, thus drive lifting shell 18 rise, make end face scraper 34 away from bolt blank 39, then control the main oil cylinder 4 stop, again start switch motor 38 positive rotation, thus through drive disc 22 drive rotating shaft 21 along horizontal sliding groove 20 outwards sliding, in rotating shaft 21 come to disc inclined groove 23 and disc arc groove 24 intersection, rotating wheel 28 exit telescopic rail 30, and limit spring blade 31 cooperation, drive disc 22 continue to rotate, through ratchet 26 push over plate 29, drive rotating wheel 28 rotation, in rotating shaft 21 come to disc arc groove 24 end, ratchet 26 drive rotating wheel 28 rotation 60 degrees, make adjacent two over plate 29 again and limit spring blade 30 close, then switch motor 38 reverse, drive rotating shaft 21 again come to disc inclined groove 23 and disc arc groove 24 intersection, ratchet 26 over over plate 29, switch motor 38 again positive rotation, thus transmission ratchet 26 push rotating wheel 28 again rotation 60 degrees, drive six prism block 32 rotation 60 degrees, make circumference scraper 35 towards axis;Then switch motor 38 reverse, when rotating shaft 21 come to disc inclined groove 23 end, rotating shaft 21 return initial position, six six prism block 32 return initial position, at this time circumference scraper 35 towards ring.

[0050] Then control the rotating motor 11 rotation, thus drive bolt blank 39 follow rotation;Control the main oil cylinder 4 stretch out, drive circumference scraper 35 down, along with circumference scraper 35 top blade and bolt blank 39 outer circumference wall contact, through circumference scraper 35 down and bolt blank 39 rotation, can bolt blank 39 outer circumference wall on the oxidation impurities to scrape, complete circumference oxide layer cleaning work.

[0051] Step five, forging processing:

[0052] When the circumferential oxide layer cleaning work is completed, the main oil cylinder 4 is controlled to retract, driving the sliding plate 3 to move upwards, thereby driving the lifting shell 18 to rise, making the circumferential scraper 35 away from the bolt blank 39, the clamping cylinder 8 is controlled to retract, driving the clamping block 7 to release the bolt blank 39, and then the external air compression equipment is controlled to introduce high-pressure air into the air jet 12, so that the high-pressure air is sprayed out of the air jet 12 to blow off the oxide layer debris; then the switching motor 38 is started to rotate forward, driving the driving disc 22 to rotate counterclockwise (counterclockwise) Figure 8 ), driving the rotating shaft 21 to slide outward along the horizontal sliding groove 20, thereby driving the six-prong block 32 to slide away from the axis, clearing the space in the middle of the lifting shell 18, and then the switching motor 38 is stopped, the main oil cylinder 4 is controlled to extend, driving the upper die 16 to descend, when the six-prong block 32 and the lower die 2 are tightly attached, the main oil cylinder 4 continues to extend to compress the slide rod spring 15, driving the upper die 16 to penetrate into the central perforation of the lifting shell 18, so that the upper end of the bolt blank 39 enters the die hole 17, and the upper end of the bolt blank 39 is forged into a hexagonal shape. After two times of forging and pressing of the bolt blank 39 by controlling the extension and retraction of the main oil cylinder 4, the main oil cylinder 4 is controlled to retract, driving the six-prong block 32 to rise away from the lower die 2, and then the external cold water equipment is controlled to introduce cooling water into the cooling water jet 13, and the cooling water jet 13 sprays cooling water on the bolt blank 39 for preliminary cooling, completing the forging and pressing work.

[0053] Step six, burr removal:

[0054] When the forging and pressing work is completed, the switching motor 38 continues to rotate forward, thereby driving the rotating shaft 21 to slide outward along the horizontal sliding groove 20 through the driving disc 22, when the rotating shaft 21 comes to the intersection of the disc inclined groove 23 and the disc arc-shaped groove 24, the rotating wheel 28 exits the extension track 30 and cooperates with the limit spring 31 to drive the driving disc 22 to continue to rotate, pushing the turnover plate 29 through the pawl 26, driving the rotating wheel 28 to rotate, when the rotating shaft 21 comes to the end of the disc arc-shaped groove 24, the pawl 26 drives the rotating wheel 28 to rotate 60 degrees, and then the switching motor 38 is reversed, driving the rotating shaft 21 to come to the intersection of the disc inclined groove 23 and the disc arc-shaped groove 24 again, the pawl 26 passes the turnover plate 29, the switching motor 38 rotates forward again, thereby driving the pawl 26 to push the rotating wheel 28 to rotate 60 degrees again, thereby driving the six-prong block 32 to rotate, making the working surface 33 face the axis; then the switching motor 38 is reversed, when the rotating shaft 21 comes to the end of the disc inclined groove 23, the rotating shaft 21 returns to the initial position, and the six six-prong blocks 32 return to the initial position, at this time the working surface 33 faces the axis and forms a regular hexagonal hole.

[0055] Then control the main oil cylinder 4 stretch, drive six prism block 32 down, press the flash produced by bolt blank 39 forging, with the main oil cylinder 4 continue to stretch, thereby compressing slide bar spring 15, when the upper die 16 lower surface and six prism block 32 contact, the main oil cylinder 4 will six prism block 32 press tightly, control the lower oil cylinder 5 stretch, push bolt blank 39 up, thereby through six prism block 32 cut off the flash, complete the flash cleaning work.

[0056] Step seven, blanking and equipment reset:
