DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 5 A stainless steel bolt cold heading machine includes a machine body 1, a discharge port is opened on the side of the machine body 1, a disc 3 is fixedly installed on the side of the machine body 1 through a support frame 2, a slide plate 18 is fixedly installed at an angle at the discharge port, a slide groove is opened on the surface of the slide plate 18, one end of the slide plate 18 is located directly above the disc 3, and the bolts produced by the machine body 1 slide into the disc 3 through the slide plate 18 after coming out of the discharge port.

[0025] A rotating rod 4 is rotatably mounted inside the disc 3, a driving motor 5 is fixedly mounted on the lower surface of the disc 3, one end of the rotating rod 4 passes through the disc 3 and is fixedly connected to the output shaft of the driving motor 5;

[0026] A plurality of arc scrapers 6 are fixedly mounted on the rotating rod 4 , one end of the arc scraper 6 is in sliding contact with the inner wall of the disc 3 , a rectangular tube 7 is fixedly mounted on the side of the disc 3 , and a rectangular hole communicating with the rectangular tube 7 is opened on the inner wall of the disc 3 .

[0027] Start the driving motor 5, and drive the rotating rod 4 to rotate through the output shaft of the driving motor 5, and then drive the multiple arc scrapers 6 on the disc 3 to rotate through the rotating rod 4. When the bolt falls into the disc 3, the arc scraper 6 will contact the bolt and drive the bolt to rotate in the disc 3. At the same time, the bolt moves around the disc 3. When the bolt moves to the rectangular opening, it will enter the rectangular tube 7 from the rectangular opening, and finally push the bolt into the box through the rectangular tube 7 (the box is the prior art, not shown in the figure). As the arc scraper 6 continues to rotate, it will continuously drive the bolt to move into the rectangular tube 7. When the bolt falls from the discharge port onto the disc 3, it will not hit other bolts, reducing the collision between the bolts, thereby reducing the damage to the bolt shape and improving the yield rate of equipment production.

[0028] A stopper 8 is fixedly installed at the rectangular hole, and strip openings are opened on multiple arc scrapers 6. The height of the strip opening is greater than the height of the stopper 8, and the size of the strip opening is smaller than the size of the bolt. When the arc scraper 6 drives the bolt to move toward the rectangular opening, the stopper 8 will block the bolt and guide the bolt into the rectangular hole. The existence of the strip opening can ensure that the arc scraper 6 continues to rotate, and the bolt will not pass through the strip opening. The stopper 8 facilitates the bolt to enter the rectangular tube 7.

[0029] A wind collecting cylinder 9 is fixedly installed on the lower surface of the disc 3, and a rotating shaft 10 is rotatably installed on the lower surface of the disc 3 through a supporting block. A fan 11 is fixedly installed on one end of the rotating shaft 10, and the fan 11 is located in the wind collecting cylinder 9. One end of the wind collecting cylinder 9 is fixedly connected to multiple air ducts 12, and the other ends of the multiple air ducts 12 are all connected to the rectangular tube 7. A transmission assembly for driving the rotating shaft 10 to rotate is provided on the rotating rod 4, and the transmission assembly includes a first bevel gear 13 fixedly sleeved on the rotating rod 4 and a second bevel gear 14 fixedly sleeved on the rotating shaft 10, and the first bevel gear 13 is meshingly connected with the second bevel gear 14.

[0030] When the driving motor 5 drives the rotating rod 4 to rotate, it will drive the first bevel gear 13 to rotate, and then drive the rotating shaft 10 to rotate through the second bevel gear 14, so as to drive the fan 11 to rotate through the rotating shaft 10, thereby generating a large amount of wind in the wind collecting tube 9, and the wind is then blown into the rectangular tube 7 through the wind duct 12, so as to cool the bolts that have just been produced.

[0031] A plurality of filter holes are provided on the lower surface of the rectangular tube 7, a guide plate 15 is fixedly installed on the lower surface of the rectangular tube 7 at an angle, an L-shaped frame 16 is fixedly installed on the rectangular tube 7, an oil collecting box 17 is placed on the L-shaped frame 16, a large amount of oil will adhere to the cold-headed bolts, when the bolts move in the rectangular tube 7, the oil will pass through the filter holes and drip onto the guide plate 15, and then flow along the guide plate 15 to the oil collecting box 17, so as to recover the oil.

[0032] In the utility model, the output shaft of the driving motor 5 drives the rotating rod 4 to rotate, and then the rotating rod 4 drives the multiple arc scrapers 6 on the disc 3 to rotate. When the bolt falls into the disc 3, the arc scraper 6 will contact the bolt and drive the bolt to rotate in the disc 3. When the bolt moves to the rectangular opening, it will enter the rectangular tube 7 from the rectangular opening. As the arc scraper 6 continues to rotate, it will continuously drive the bolt to move into the rectangular tube 7. When the bolt falls from the discharge port to the disc 3, it will not hit other bolts, thereby reducing collisions between bolts, thereby reducing damage to the bolt shape and improving the yield rate of equipment production.

[0033] In general, in view of the technical problem: the produced bolts fall directly from the discharge port into the receiving box, and the bolts will hit the bolts in the receiving box during the falling process, which is easy to cause damage to the bolt shape and affect the yield of the bolts; a technical solution is adopted: the bolts that fall onto the disc 3 are driven to rotate by the cooperation of the driving motor 5, the rotating rod 4, the arc scraper 6, the disc 3 and the rectangular tube 7; because the implementation process of the technical solution is: the rotating rod 4 is driven to rotate by the output shaft of the driving motor 5, and then the multiple arc scrapers on the disc 3 are driven by the rotating rod 4 The scraper 6 rotates, and when the bolt falls into the disc 3, the arc scraper 6 will contact the bolt and drive the bolt to rotate in the disc 3. When the bolt moves to the rectangular opening, it will enter the rectangular tube 7 from the rectangular opening. As the arc scraper 6 continues to rotate, it will continuously drive the bolt to move into the rectangular tube 7. When the bolt falls from the discharge port onto the disc 3, it will not hit other bolts. Therefore, the technical problem can be solved inevitably, and the technical effect achieved is: reducing the collision between bolts, thereby reducing the damage to the bolt shape and improving the yield rate of equipment production.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
