Description

Technical Field

[0001] This utility model relates to the field of fastener production technology, specifically to a cold heading machine feeding device for fastener production. Background Technology

[0002] Fasteners are a general term for a class of mechanical parts used to connect and secure mechanical parts or structural components. Their function is to firmly connect two or more components together, maintain a relatively fixed positional relationship during operation, and withstand certain loads and forces. There are many types of fasteners, the most common being bolts, nuts, screws, washers, rivets, and pins.

[0003] In the production process of fasteners, feeding devices are frequently used. Although existing feeding devices can achieve basic feeding functions, they generally do not have the function of adjusting the distance between the feeding wheels. As a result, the feeding device can only transport fastener raw materials of one diameter. When transporting fastener raw materials of different diameters, a corresponding feeding device is required. This not only increases production costs but also reduces the production efficiency of fasteners. Therefore, it is necessary to improve the feeding device. Utility Model Content

[0013] As a preferred embodiment of this utility model, the outer surface of the limiting block is smooth, and the limiting block has a T-shaped appearance.

[0014] As a preferred embodiment of this utility model, the mounting plate has a through hole on its front side, and the inner surface of the through hole is movably connected to the outer surface of the drive shaft and the round rod.

[0032] like Figures 1-6The diagram illustrates a feeding device for a cold heading machine in fastener production according to an embodiment of this disclosure. It includes a mounting plate 1, a U-shaped plate 2 movably connected to the inner surface of the back of the mounting plate 1, a round rod 3 movably sleeved inside the U-shaped plate 2, a driven wheel 4 fixedly sleeved on the outer surface of the round rod 3, a drive motor 5 located to the left of the round rod 3 fixedly connected inside the U-shaped plate 2, a drive shaft 6 fixedly sleeved at the other end of the output shaft of the drive motor 5, and a driving wheel 7 fixedly sleeved on the outer surface of the drive shaft 6. The driving wheel 7 is connected to the driven wheel 4 via a conveyor belt 8. The outer surfaces of wheel 7 and driven wheel 4 are movably connected to the back of mounting plate 1. The other ends of rod 3 and drive shaft 6 pass through mounting plate 1 and extend to the outside of mounting plate 1, and are fixedly sleeved with feeding wheel 9. The outer surface of feeding wheel 9 is movably connected to the front of mounting plate 1. A drive motor 10 is fixedly connected to the back of mounting plate 1. A lead screw 11 is fixedly sleeved at the other end of the output shaft of drive motor 10. A movable plate 12 is threaded onto the outer surface of lead screw 11. A connecting rod 13 is hinged to the outside of movable plate 12. The other end of connecting rod 13 is hinged to the outer surface of U-shaped plate 2.

[0033] When the drive motor 10 is running, the lead screw 11 will rotate, causing the movable plate 12 to move to the right. This will cause the two connecting rods 13 to rotate, causing the two U-shaped plates 2 to move in opposite directions. This will cause the four feeding wheels 9 to move in opposite directions in pairs, thus achieving the purpose of adjusting the spacing between the four feeding wheels 9, which is convenient for feeding fastener materials of different diameters.

[0034] In some examples, a fixing block 14 is movably sleeved on the outer surface of the other end of the lead screw 11, and the other end of the fixing block 14 is fixedly connected to the back of the mounting plate 1.

[0035] The design of the fixing block 14 serves to support the lead screw 11.

[0036] In some examples, a limiting rod 15 is fixedly connected to the back of the mounting plate 1, and the outer surface of the limiting rod 15 is movably sleeved with the inner surface of the movable plate 12.

[0037] The design of the limit rod 15 serves to limit the movement of the movable plate 12.

[0038] In some examples, there are two limit rods 15, both of the same size, and the two limit rods 15 are symmetrical about the center of the movable plate 12.

[0039] The design of the two limit rods 15 provides a better limiting effect on the movable plate 12, making the horizontal movement of the movable plate 12 more stable.

[0040] In some examples, a mounting bracket 16 is fixedly connected to the center of the back of the mounting plate 1, and a protective motor 17 is fixedly sleeved on the inner surface of the mounting bracket 16.

[0041] The design of the mounting bracket 16 serves to secure the protective motor 17.

[0042] In some examples, the other end of the output shaft of the protective motor 17 is fixedly sleeved with a rotating shaft 18, and a rotating plate 19 is fixedly sleeved on the outer surface of the rotating shaft 18.

[0043] When the protective motor 17 is running, it will cause the rotating shaft 18 to drive the rotating plate 19 to rotate.

[0044] In some examples, rotating rods 20 are hinged to both the front and back of the rotating plate 19. A connecting plate 21 is hinged to the other end of the rotating rod 20. A transparent protective plate 22 is fixedly connected to the inner side of the connecting plate 21. There are two transparent protective plates 22, and the back sides of the two transparent protective plates 22 are movably connected to the front of the mounting plate 1.

[0045] The rotation of the two rotating rods 20 will cause the two connecting plates 21 to move towards each other, which in turn causes the two transparent protective plates 22 to move towards each other and fit together, thus achieving the purpose of protecting the fastener material from being fed and preventing the fastener material from breaking and splashing and injuring people.

[0046] In some examples, the front of the mounting plate 1 is provided with a groove 23, and the inner surface of the groove 23 is movably connected to a limiting block 24. The top of the limiting block 24 is fixedly connected to the bottom of the transparent protective plate 22.

[0047] The design of the slide 23 and the limiting block 24 serves to limit the movement of the transparent protective plate 22, ensuring the stability of the horizontal movement of the transparent protective plate 22.

[0048] In some examples, the outer surface of the limit block 24 is smooth, and the appearance of the limit block 24 is T-shaped.

[0049] This design allows the limiting block 24 to slide more smoothly inside the groove 23.

[0050] In some examples, the front of the mounting plate 1 has a through hole 25, and the inner surface of the through hole 25 is movably connected to the outer surface of the drive shaft 6 and the round rod 3.

[0051] The through hole 25 is designed to limit the movement of the drive shaft 6 and the round rod 3.

[0052] Working principle and usage process of this utility model:

[0053] When feeding fastener materials of different diameters, the drive motor 10 is started first, which causes the lead screw 11 to rotate, driving the movable plate 12 to move to the right. This causes the two connecting rods 13 to rotate, driving the two U-shaped plates 2 to move in opposite directions. This, in turn, causes the four feeding wheels 9 to move in opposite directions in pairs, thus achieving the purpose of adjusting the spacing between the four feeding wheels 9. Then, the fastener material is placed between the four feeding wheels 9. Subsequently, the two transmission motors 5 are started, which causes the transmission shaft 6 to drive the drive wheel 7 and the feeding wheel 9 to rotate. The rotation of the drive wheel 7 drives the driven wheel 4 to rotate through the conveyor belt 8, which in turn causes the rod 3 to drive the feeding wheel 9 to rotate, thus achieving the purpose of feeding the fastener material.

[0054] When there are cracks inside the fastener material, the fastener material is prone to breakage and splashing during the feeding process. At this time, starting the protective motor 17 will cause the rotating shaft 18 to drive the rotating plate 19 to rotate, which in turn causes the two rotating rods 20 to rotate and drive the two connecting plates 21 to move towards each other. This causes the two transparent protective plates 22 to move towards each other. When the two transparent protective plates 22 are in contact with each other, the purpose of protecting the fastener material during feeding is achieved, avoiding the occurrence of fastener material breakage and splashing that could injure people, and improving the protective performance of the device.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
