Description

Technical Field

[0001] This utility model belongs to the field of cold rolling mill technology, and in particular relates to a continuous feeding device for steel pipe cold rolling mill. Background Technology

[0002] A cold rolling mill is a new type of equipment for cold rolling steel bars. Cold-rolled ribbed steel bars produced by a cold rolling mill are a replacement for cold-drawn low-carbon steel wire in prestressed concrete components. In cast-in-place concrete structures, they can replace Grade I steel bars, thus saving steel. They are one of the better types of cold-worked steel products.

[0003] Existing cold rolling mills generally use manual feeding. This feeding method requires workers to move the rolled material from one place to the side of the cold rolling mill. This traditional feeding method not only consumes a lot of manpower, but also requires constant machine stops and adjustments in order to align the rolled material with the feed inlet of the cold rolling mill, resulting in low feeding accuracy and efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a continuous feeding device for a cold rolling mill of steel pipes. Through the action of a transmission rod, this device can continuously feed multiple steel pipes, rapidly conveying them from the transport line to the feed inlet of the cold rolling mill. The S-shaped moving block prevents multiple steel pipes from rolling into the conveying trough simultaneously, ensuring that the pipes fall into the trough in an orderly manner. This device helps maintain the continuity and stability of the production process, reduces quality fluctuations caused by frequent starts and stops, and solves the problem of low accuracy and efficiency in manual feeding, which requires constant stops to align the rolled material with the feed inlet of the cold rolling mill.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A continuous feeding device for a cold rolling mill for steel pipes includes a base, a support fixed on the upper surface of the base, and a conveying groove fixed at one end of the support.

[0007] A number of transmission rods are fixed on one side of the conveying groove, and the transmission rods are cylindrical structures.

[0008] The transmission rod is inclined relative to the base, and the end of the transmission rod closer to the transmission groove is lower than the other end;

[0009] A motor is fixed to the upper surface of the base, and a threaded rod is fixed to the output shaft of the motor. A threaded tube is threadedly connected to the outer ring of the threaded rod.

[0010] The outer ring of the threaded tube is fixed with a bearing, and the outer ring of the bearing is fixed with a positioning bracket;

[0011] A connecting plate is fixed to one end of the positioning frame, a number of support rods are fixed to one side of the connecting plate, and a placement shell is fixed to one end of each support rod.

[0012] A positioning rod is fixed to the side of the transmission rod near the conveying groove, and a moving block is rotatably connected to the outside of the positioning rod.

[0013] The present invention is further configured such that: the placement shell has an arc-shaped structure, and the surface of the moving block has a through hole;

[0014] The positioning rod passes through the through hole, and the moving block has an "S" shaped structure.

[0015] The present invention is further configured such that: a limiting rod is fixed on the upper surface of the base, and a limiting tube is fixed on the surface of the positioning frame;

[0016] The limiting rod passes through the limiting tube.

[0017] The present invention is further configured such that: a connecting rod is fixed to the bottom of the movable block, and an adjusting plate is fixed to one end of the connecting rod;

Specific Implementation Example 1

[0042] Please see Figure 1-6 This utility model is a continuous feeding device for a cold rolling mill of steel pipes, including a base 1, a bracket 2 fixed on the upper surface of the base 1, a conveying groove 3 fixed at one end of the bracket 2; several transmission rods 4 fixed on one side of the conveying groove 3, the transmission rods 4 having a cylindrical structure; the transmission rods 4 are inclined relative to the base 1, and the end of the transmission rod 4 near the conveying groove 3 is lower than the other end; a motor 5 is fixed on the upper surface of the base 1, a threaded rod 6 is fixed on the output shaft of the motor 5, and a threaded tube 7 is threadedly connected to the outer ring of the threaded rod 6; a bearing 8 is fixed to the outer ring of the threaded tube 7, and a positioning frame 9 is fixed to the outer ring of the bearing 8; a connecting plate 10 is fixed to one end of the positioning frame 9, several support rods 11 are fixed to one side of the connecting plate 10, and a placement shell 12 is fixed to one end of the support rods 11; a positioning rod 13 is fixed to the side of the transmission rod 4 near the conveying groove 3, and a moving block 14 is rotatably connected to the outside of the positioning rod 13; a limit rod 16 is fixed on the upper surface of the base 1, and a limit tube 17 is fixed on the surface of the positioning frame 9; the limit rod 16 passes through the limit tube 17.

[0043] Specifically, the housing 12 has an arc-shaped structure, and the moving block 14 has a through hole 15 on its surface; the positioning rod 13 passes through the through hole 15, and the moving block 14 has an "S"-shaped structure.

[0044] Furthermore, a connecting rod 18 is fixed to the bottom of the movable block 14, and an adjusting plate 19 is fixed to one end of the connecting rod 18; a hydraulic cylinder 20 is fixed to the upper surface of the base 1, and the output shaft of the hydraulic cylinder 20 is fixedly connected to the adjusting plate 19.

[0045] The operation process of this embodiment is as follows: When using this device, the steel pipe to be processed in the cold rolling mill is placed in the arc-shaped placement hole 12, and the motor 5 is turned on. The output shaft of the motor 5 drives the threaded rod 6 at one end to rotate. When the threaded rod 6 rotates, it drives the threaded tube 7 on its outer side to move downward. When the threaded tube 7 moves downward, the bearing 8 on its outer side also moves accordingly. Since the inner ring of the bearing 8 is fixedly connected to the threaded tube 7, and the outer ring of the bearing 8 is fixedly connected to the positioning frame 9, and the positioning frame 9 is limited by the limit rod 16 on its outer side, the positioning frame 9 will not rotate with the rotation of the threaded tube 7, but will only move up and down. When the positioning frame 9 drives the placement shell 12 to move downward, the placement shell 12 moves downward through the gap of the transmission rod 4, and the steel pipe is released from the transmission rod 4. Since the transmission rod 4 is inclined, the steel pipe rolls towards one end of the conveying groove 3. When the moving block 14 is tilted up at one end, it intercepts the steel pipe. When the steel pipe needs to fall into the conveying trough 3, the hydraulic cylinder 20 can be opened. The output shaft of the hydraulic cylinder 20 drives the adjusting plate 19 and the connecting rod 18 at one end to move downward, that is, pull the tilted end of the moving block 14 downward. The other end of the moving block 14 pushes the steel pipe into the conveying trough 3 and sends the steel pipe into the cold rolling mill body 1 through the conveying trough 3. This device can continuously feed multiple steel pipes through the inclined transmission rod 4, and quickly convey the steel pipes from the conveyor line to the feed port of the cold rolling mill body 21. The S-shaped moving block 14 can prevent multiple steel pipes from rolling into the conveying trough 3 at the same time, so that the steel pipes fall into the conveying trough 3 in an orderly manner. This device helps to maintain the continuity and stability of the production process and reduce quality fluctuations caused by frequent start-ups and stops. Specific Implementation Example 2

[0047] Please see Figure 5-6 Based on the first specific embodiment, a cold rolling mill body 21 is fixed on the upper surface of the base 1; one end of the conveying groove 3 is in contact with the inlet of the cold rolling mill body 21, and a positioning plate 22 is fixed on the end of the conveying groove 3 away from the cold rolling mill body 21.

[0048] Specifically, the bottom of the conveying trough 3 has an adjustment groove 23, and the surface of the positioning plate 22 has an adjustment hole 24; an adjustment rod 25 is movably connected inside the adjustment hole 24, and a push plate 26 is fixed to one end of the adjustment rod 25.

[0049] Furthermore, an adjusting block 27 is fixed to the bottom of the push plate 26, and the adjusting block 27 passes through the adjusting groove 23; a support plate 28 is fixed to the bottom of the positioning plate 22, and a spring 29 is fixed between the support plate 28 and the adjusting block 27.

[0050] The operation process of this embodiment is as follows: When the steel pipe enters the conveying groove 3, the operator pulls the adjusting rod 25, so that the push plate 26 at one end of the adjusting rod 25 is close to the positioning plate 22. After the steel pipe falls into the conveying groove 3, the operator releases the adjusting rod 25. At this time, under the action of the spring 29 at the bottom of the push plate 26, the spring 29 pushes the push plate 26, and the push plate 26 can push the steel pipe inside the conveying groove 3 to move towards the feed port of the cold rolling mill body 21. This device, through the push plate 26, continuously pushes multiple steel pipes into the cold rolling mill body 21, which not only reduces the labor intensity of the operators, but also reduces the frequent manual replacement and adjustment of materials, thereby saving a lot of manpower.
