Description

Technical Field

[0001] This utility model relates to the field of U-pin production, and in particular to a feeding mechanism for U-pin production. Background Technology

[0002] U-pins are standard mechanical fasteners, U-shaped in shape, and usually made of carbon steel or stainless steel (such as 304 or 316). They have threaded holes or through holes at both ends and are used to fix components such as pipes and hydraulic supports. They are secured by inserting cotter pins or bolts to prevent loosening. They are characterized by simple structure and strong load-bearing capacity, and are widely used in mining machinery, hydraulic systems and other fields.

[0003] When producing U-shaped pins, the long bar blanks need to be straightened first to improve their concentricity. Then, the long bar blanks are cut into multiple short bar blanks of the required length. After that, the ends of the short bar blanks are tapped with threads. Finally, the threaded short bar blanks are bent into U-shapes using cold bending or hot bending equipment. The existing feeding process of feeding the short bar blanks into the bending equipment is generally achieved by a pusher plate feeding machine. For example, Chinese patent CN210794867U discloses a short bar feeding machine. After the pusher plate passes through the boss to remove the material, only one short bar blank enters the support groove each time it moves upward. Then, the side push rod pushes the short bar blank into the next equipment for clamping or processing, reducing the labor intensity of manual feeding.

[0004] In the above scheme, multiple short bar billets are pushed upward by a pusher plate, while the boss ensures that only one short bar billet is pushed into the inside of the support groove. Then, the side push rod pushes the single short bar billet for feeding. However, when the boss removes the excess short bar billets, the short bar billets will fall from a height. This causes the threaded end of the short bar billet to be easily damaged by impact when using a pusher plate feeding machine for U-pin production. There is a problem of unstable feeding of U-pin billets, which is easily damaged by impact. Therefore, a feeding mechanism for U-pin production is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding mechanism for U-shaped pin production, so as to solve the problem mentioned in the background art that the feeding of U-shaped pin blanks is unstable and easily damaged by impact. The technical solution of this utility model provides a solution that is significantly different from the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A feeding mechanism for producing U-shaped pins includes a fixed plate and a feeding plate. The blank body is located inside the fixed plate. A housing is provided between the fixed plate and the feeding plate. A clamping mechanism for clamping the blank body is provided on one side of the housing. A transmission mechanism for providing power to the clamping mechanism is provided inside the housing. A drive mechanism for driving the housing to rotate is provided on the other side of the housing.

[0007] Preferably, the material stationary plate is provided with a material transfer groove inside, and a guide plate is provided on the side of the material stationary plate. The billet body enters the material transfer groove along the guide plate. One end of the feeding plate is inclined downward, and the other end of the feeding plate is provided with a through groove.

[0008] Preferably, the housing is provided with brackets on both sides, and a cam and a support shaft are provided inside the housing. The cam is fixedly mounted on the support shaft, and both ends of the support shaft pass through the housing and are respectively installed inside the two brackets.

[0009] Preferably, the side of the housing is provided with a sealing plate, and the side of the sealing plate is provided with a sleeve. The sleeve is mounted on the support shaft. The drive mechanism includes a motor, a drive gear and a driven gear. The motor is mounted on the bracket, the drive gear is connected to the motor shaft, the drive gear and the driven gear mesh, and the driven gear is mounted on the sleeve.

[0010] Preferably, the clamping mechanism includes a material support plate, a fixed clamping plate, and a movable clamping plate. One end of the material support plate is installed on the side of the housing, the fixed clamping plate is installed on the other end of the material support plate, and a rubber block is provided on the side of the movable clamping plate.

[0011] Preferably, the transmission mechanism includes a guide post, a spring, a connecting block, and a roller. The roller is in contact with the cam, the connecting block is connected to the roller shaft, one end of the guide post is connected to the connecting block, the other end of the guide post passes through the housing and is connected to the movable clamping plate, the spring is located inside the housing and is sleeved on the guide post.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention uses an electric telescopic rod to push multiple billet bodies sequentially into the material transfer trough along a guide plate. Then, a motor drives the housing to rotate, and the support plate drives the billet bodies to rotate with the housing. As the housing rotates, the movable clamping plate gradually approaches the fixed clamping plate, thereby clamping and fixing the billet bodies onto the support plate. When the housing drives the billet bodies to rotate above the loading plate, the movable clamping plate moves away from the fixed clamping plate, and the billet bodies fall onto the loading plate by gravity, and then enter the bending equipment along the loading plate. This achieves stable feeding of individual billet bodies and avoids impacts to both ends of the billet bodies, which could damage the functional structures on the billet bodies.

[0018] Please see Figure 1-3 In this utility model, a feeding mechanism for producing U-shaped pins includes a fixed plate 4 and a feeding plate 5. The blank body 3 is located inside the fixed plate 4. A housing 1 is provided between the fixed plate 4 and the feeding plate 5. The side of the housing 1 is provided with a support plate 7, a fixed clamping plate 701 and a movable clamping plate 8 for clamping the blank body 3. Both sides of the housing 1 are provided with brackets 2. The side of the brackets 2 is provided with a motor 6. The inside of the housing 1 is provided with a cam 9 and a support shaft 901. The cam 9 is fixedly installed on the support shaft 901. Both ends of the support shaft 901 pass through the housing 1 and are respectively installed inside the two brackets 2.

[0019] One end of the material support plate 7 is installed on the side of the housing 1, and the fixed clamping plate 701 is installed on the other end of the material support plate 7. The side of the movable clamping plate 8 is provided with a rubber block 801, and the interior of the rubber block 801 has a porous structure.

[0020] Example 1: Please refer to Figure 1-3 In this embodiment of the utility model, a feeding mechanism for producing U-shaped pins is provided. The inside of the fixed plate 4 is provided with a transfer groove 401, and the side of the fixed plate 4 is provided with a guide plate 402. The blank body 3 enters the inside of the transfer groove 401 along the guide plate 402. One end of the feeding plate 5 is inclined downward, and the other end of the feeding plate 5 is provided with a through groove 501. The receiving plate 7 can pass through the inside of the transfer groove 401 and the through groove 501.

[0021] A sealing plate 101 is provided on the side of the housing 1, and a sleeve 102 is provided on the side of the sealing plate 101. The sleeve 102 is mounted on the support shaft 901. The sealing plate 101 and the support shaft 901 are connected by bearings. The driving mechanism includes a motor 6, a driving gear 601 and a driven gear 103. The motor 6 is mounted on the bracket 2. The driving gear 601 is connected to the shaft of the motor 6. The driving gear 601 and the driven gear 103 mesh. The driven gear 103 is mounted on the sleeve 102. After the motor 6 is started, it drives the driving gear 601, the driven gear 103, the sleeve 102, the sealing plate 101 and the housing 1 to rotate in sequence.

[0022] A roller 805 is provided on the side of the cam 9. The roller 805 is in contact with the cam 9. The connecting block 804 is connected to the roller 805 shaft. One end of the guide post 802 is connected to the connecting block 804. The other end of the guide post 802 passes through the housing 1 and is connected to the movable clamping plate 8. The spring 803 is located inside the housing 1 and is sleeved on the guide post 802.

[0023] An electric telescopic rod (not shown in the figure) pushes multiple blank bodies 3 sequentially into the interior of the transfer groove 401 along the guide plate 402. At this time, the support plate 7 is located inside the transfer groove 401, so that a single blank body 3 is exactly on the support plate 7. Then, the motor 6 drives the housing 1 to rotate, and the support plate 7 drives the blank body 3 to rotate with the housing 1. As the housing 1 rotates, the roller 805 moves along the surface of the cam 9, and the roller 805 gradually approaches the convex surface on the cam 9, and sequentially pushes the guide post 802 and the movable clamping plate 8 towards the fixed clamping plate 701, thereby clamping and fixing the blank body 3 on the support plate 7. At the same time, the movable clamping plate 8 pushes the rubber block 801 to continuously squeeze towards the blank body 3, so that the rubber block 801 gradually deforms, and the clamping force of the movable clamping plate 8 and the fixed clamping plate 701 on the blank body 3 gradually increases. As the housing 1 continues to rotate, when the roller 805 is in contact with the convex surface of the cam 9, the clamping force of the movable clamping plate 8 and the fixed clamping plate 701 on the blank body 3 is at its maximum, which can prevent the blank body 3 located above the housing 1 from falling off. When the roller 805 moves away from the convex surface of the cam 9 with the rotation of the housing 1, the blank body 3 is located inside the through groove 501 of the feeding plate 5, and the movable clamping plate 8 moves away from the fixed clamping plate 701. The blank body 3 falls onto the feeding plate 5 by gravity, and then enters the interior of the bending equipment along the feeding plate 5, thereby realizing the stable feeding of a single blank body 3 and avoiding the impact on both ends of the blank body 3, which would damage the functional structure on the blank body 3.

[0024] Then the housing 3 moves the material support plate 7 to the inside of the transfer groove 401 again, and repeats the above operation to achieve continuous and stable feeding of a single billet body 3.

[0025] The working principle of this utility model is as follows: the electric telescopic rod pushes multiple blank bodies 3 sequentially into the interior of the transfer groove 401 along the guide plate 402. Then, the motor 6 drives the housing 1 to rotate, and the support plate 7 drives the blank body 3 to rotate with the housing 1. As the housing 1 rotates, the movable clamping plate 8 gradually approaches the fixed clamping plate 701, thereby clamping and fixing the blank body 3 on the support plate 7. When the housing 1 drives the blank body 3 to rotate into the interior of the through groove 501, the movable clamping plate 8 automatically moves away from the fixed clamping plate 701, and the blank body 3 falls onto the feeding plate 5 by gravity, and then enters the interior of the bending equipment along the feeding plate 5. This achieves stable feeding of a single blank body 3 and avoids the two ends of the blank body 3 being impacted, which could damage the functional structure on the blank body 3.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
