Description

Technical Field

[0001] This utility model belongs to the field of metal processing equipment, and in particular relates to a feeding structure for a chamfering machine. Background Technology

[0002] A chamfering machine is an essential piece of equipment in the production and processing of metal pipes, used to chamfer the edges of metal pipes. Currently, when using a chamfering machine to chamfer metal pipes, it is generally necessary to manually place the metal pipes into the feeding and conveying structure of the chamfering machine, which results in insufficient automation and affects production efficiency; or expensive robotic arms can be used to replace manual placement of metal pipes, which significantly increases processing costs. Summary of the Invention

[0003] Based on the above-mentioned problems in the existing technology, this utility model provides a feeding structure for a chamfering machine, including a feeding frame and a feeding rack. One side of the feeding frame is the discharge side, and the bottom of the discharge side is provided with a discharge port. The feeding rack is located on one side of the discharge port, and the feeding rack is provided with an intermittent lifting structure for feeding.

[0004] The intermittent lifting structure includes a drive sprocket and a driven sprocket that are rotatably mounted on the feeding frame. The drive sprocket is connected to a drive motor. The drive sprocket and the driven sprocket are arranged vertically and meshed with the same lifting chain. Several lifting hooks are fixedly mounted on the lifting chain. The drive motor drives the lifting hooks to move up and down cyclically through the cooperation of the lifting chain, the drive sprocket and the driven sprocket.

[0005] The chamfering machine feeding structure includes two driving sprockets and two driven sprockets. One driving sprocket and one driven sprocket cooperate to form a set and are meshed with a lifting chain. The two sets are located on both sides of the discharge port. The driving sprockets of the two sets are coaxially connected to the drive motor. The number and distribution of lifting hooks in the two sets are the same. The lifting hook is provided with a connecting pin that matches two pins of a link of the lifting chain. The lifting hook is fixedly connected to the link of the lifting chain through the connecting pin, and the connecting pin serves as the pin of the link.

[0006] The side of the lifting hook that contacts the material is inclined downwards in a direction away from the lifting chain.

[0007] The width of the feeding frame is smaller than the width of the feeding frame, so that both ends of the material can extend outside the feeding frame, making it convenient for the lifting hook to lift the material. The two sets of driving sprockets and driven sprockets are located on the outer sides of the feeding frame respectively.

[0008] The side opposite to the discharge side of the feeding frame is the back side of the feeding frame. The bottom of the feeding frame is provided with a bottom beam extending from the back side to the discharge side, and one end of the bottom beam on the back side is higher than the end on the discharge side. The discharge port is located on the upper surface of the bottom beam.

[0009] The material feeding frame has a limiting frame above the discharge port on the discharge side. The lower surface of the limiting frame is a limiting slope that gradually slopes downward from the back side to the discharge side. The limiting slope and the bottom beam cooperate to form the discharge port. The minimum height of the discharge port is greater than the height of one material and less than the overlap height of two materials.

[0010] The feeding frame is equipped with a top material block at the corresponding discharge port. An adjusting bolt is rotatably installed on the top material block, and the top material block is telescopically installed on the feeding frame through the adjusting bolt.

[0011] The feeding frame is equipped with baffles on all sides except the back side and the discharge side to prevent the pipe from falling out of the feeding frame from the side.

[0012] The beneficial effects of this utility model are as follows: An intermittent lifting structure consisting of a drive motor, a drive sprocket, a driven sprocket, a lifting chain, and a lifting hook is provided on the discharge side of the feeding frame. The intermittent lifting structure lifts the metal pipe material intermittently to the feeding conveying structure of the chamfering machine, eliminating the need for manual material placement, reducing labor costs, and having the advantages of automation, simple and reasonable structure, and low manufacturing and maintenance costs.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] As attached Figure 1-7The chamfering machine feeding structure shown includes a cubical feeding frame 1 and a feeding rack 2. The opening of the feeding frame 1 faces upward and is used to put in metal pipes. One side of the feeding frame 1 is the discharge side, and the bottom of the discharge side is provided with a discharge port 3. The feeding rack 2 is located on one side of the discharge port 3. The width of the feeding rack 2 is smaller than the width of the feeding frame 1. The feeding rack 2 is provided with an intermittent lifting structure for feeding.

[0022] The intermittent lifting structure includes a driving sprocket 4 and a driven sprocket 5 rotatably mounted on the feeding frame 2. There are two driving sprockets 4 and two driven sprockets 5, each forming a set and meshing with the same lifting chain 6. The two sets are located on opposite sides of the discharge port 3, i.e., the two sets of driving sprockets 4 and driven sprockets 5 are located on the outer sides of the feeding frame 2. The two sets of driving sprockets 4 are coaxially connected to a reduction gearbox 7, which in turn connects to a drive motor 8. The two driven sprockets 5 are also coaxially connected. Within the same set, the driving sprockets 4 and driven sprockets 5 are arranged vertically, with the driving sprocket 4 at the bottom and the driven sprocket 5 at the top. Above, two lifting hooks 9 are fixedly installed on each lifting chain 6. The lifting hook 9 is provided with a connecting pin 10 that matches the two pins of one link of the lifting chain 6. The lifting hook 9 is fixedly connected to the link of the lifting chain 6 through the connecting pin 10, and the connecting pin 10 serves as the pin of the link. The side of the lifting hook 9 that contacts the material is inclined downward away from the lifting chain 6. The two lifting hooks 9 divide the lifting chain 6 into two even sections. The corresponding lifting hooks 9 on the two sets of lifting chains 6 are distributed in the same way and their projections in the horizontal direction are completely overlapping. The drive motor 8 drives the lifting hook 9 to move up and down in a cyclical manner through the cooperation of the lifting chain 6, the drive sprocket 4 and the driven sprocket 5.

[0023] In a preferred embodiment, the side opposite to the discharge side of the feeding frame 1 is the back side of the feeding frame 1. The feeding frame 1 is fixedly equipped with baffles 11 on all other sides except the back side and the discharge side. The bottom of the feeding frame 1 is provided with two bottom beams 12 extending from the back side to the discharge side, and one end of the bottom beam 12 on the back side is higher than the end on the discharge side, so that the metal pipe material can automatically roll to the discharge port 3. The discharge port 3 is located on the upper surface of the bottom beam 12. On the discharge side of the feeding frame 1, two limiting frames 13 are provided above the discharge port 3. The lower surface of the limiting frame 13 is a limiting slope 14 that gradually slopes downward from the back side to the discharge side. The limiting slope 14 and the bottom beam 12 cooperate to form the discharge port 3. The setting of the limiting slope 14 can reduce the stacking height of the metal pipe material at the discharge port 3, avoiding the pressure caused by excessive stacking affecting the discharge. The minimum height of the discharge port 3 is greater than the height of one material and less than the overlap height of two materials, so that only one metal pipe can pass through the discharge port 3 at a time, which is convenient for the lifting hook 9 to pick up the material. The feeding frame 2 is provided with a top block 15 at each discharge port 3 formed by the two limiting frames 13. Two adjusting bolts 16 are rotatably installed on the top block 15. The top block 15 is telescopically installed on the feeding frame 2 through the adjusting bolts 16. The position of the top block 15 can be adjusted according to the diameter of the metal pipe by adjusting the adjusting bolts 16, which can ensure that the lifting hook 9 can only lift one pipe at a time.

[0024] The feeding frame 1 provided in this embodiment can be used to store metal pipes of suitable length. When the metal pipes are placed on the feeding frame 1, they will move along the bottom beam 12 toward the discharge port 3 under the action of gravity and move to the feeding rack 2.

[0025] When it is necessary to feed material into the chamfering machine, the drive motor 8 starts and drives the drive sprocket 4 to rotate. Then, the drive sprocket 4 drives the lifting chain 6 and the driven sprocket 5 to rotate. The lifting hook 9 on the lifting chain 6 moves with the lifting chain 6. The lifting hook 9 moves downward on the side of the lifting chain 6 away from the feeding frame 1. When it reaches the lowest point, it swings with the lifting chain 6 and moves to the bottom of the feeding frame 2. Then, it lifts the metal pipe on the feeding frame 2 from bottom to top and raises the metal pipe to the top of the feeding frame 2. The lifting hook 9 then swings with the lifting chain 6 and drives the metal pipe to fall into the feeding conveyor structure of the chamfering machine located on the other side, completing the feeding.

[0026] After the tube at the bottom of the feeding rack 2 is removed, another tube will automatically roll out from the discharge port 3. With the help of the two separately set lifting hooks 9, intermittent lifting and feeding can be achieved.

[0027] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
