[0002] Cold rolled tubes are produced by cold rolling tube mills, which are used to perform a periodic reciprocating rolling process on the blank tubes, and cold rolling the blank tubes with large diameters into cold rolled tubes with small diameters. At present, many cold rolled tube manufacturers mainly use LG series servo cold rolled tube mills (two rollers). Since the cold rolled tubes are still hot during the cold rolling process and are easy to bend, a cold rolled tube placement bracket is usually fixed at the outlet of the cold rolled tube mill to receive the produced cold rolled tubes and prevent the rolled cold rolled tubes from bending.

One side of the support frame 2 is provided with a material discharging plate 5, and the top of the material discharging plate 5 is connected to the material receiving trough 4 at a certain angle after rotation, which is convenient for the steel pipe to fall into the material discharging plate 5. One side of the material discharging plate 5 is provided with a placing rack 6 for placing steel pipes. A buffer mechanism 7 is provided between the bottom end of the placing rack 6 and the top of the first support plate 1 to buffer the impact force of the steel pipe falling on the placing rack 6. A second support plate 8 is provided below the first support plate 1. A support cylinder 9 is provided at the top of the second support plate 8. A threaded rod 10 is rotatably provided inside the support cylinder 9. A moving cylinder 11 is slidably provided inside the support cylinder 9, and the inside of the moving cylinder 11 is hollow, and the moving cylinder 11 is provided at the bottom end of the first support plate 1. The threaded rod 10 penetrates through the bottom end of the moving cylinder 11 and is threadedly connected thereto. A driving mechanism 12 for driving the threaded rod 10 to rotate is provided on one side of the threaded rod 10, which is convenient for driving the threaded rod 10 to rotate, thereby driving the moving cylinder 11 to move. The moving cylinder 11 drives the first support plate 1 and the material receiving trough 4 to move, so that the material receiving trough 4 corresponds to the position of the cold rolling mill discharge port;

[0029] The driving mechanism 12 includes a driving bevel gear 1202 and a driven bevel gear 1201. The driven bevel gear 1201 is arranged at the bottom of the threaded rod 10. One side of the support cylinder 9 is provided with a motor box 1203. Inside the motor box 1203, there is a motor 1204.

The driving bevel gear 1202 is connected to the transmission shaft of the motor 1204, and the driving bevel gear 1202 is meshed with the driven bevel gear 1201. The transmission shaft of the motor 1204 drives the driving bevel gear 1202 to rotate. Since the driving bevel gear 1202 is meshed with the driven bevel gear 1201, the driving bevel gear 1202 drives the driven bevel gear 1201 to rotate. The rotation of the driven bevel gear 1201 drives the threaded rod 10 to rotate, thereby driving the moving cylinder 11 to move;

[0030] At the bottom end of the first support plate 1, there are adjusting rods 101. There are four adjusting rods 101, which are respectively located at the four corners of the bottom end of the first support plate 1. At the bottom end of the adjusting rod 101, there is an adjusting cylinder 102, and the adjusting rod 101 is slidably connected to the adjusting cylinder 102, which is used to support the first support plate 1 and increase the stability of the first support plate 1.

[0031] Embodiment 2

The telescopic end of the cylinder 307 is connected to one end of the third rotating seat 3010. Under the action of the first rotating seat 303, the second rotating seat 306 and the third rotating seat 3010, the telescopic end of the cylinder 307 drives the material receiving groove 4 to rotate, so that the material receiving groove 4 is connected with the blanking plate 5, which is convenient for the transportation of steel pipes.

[0033] Embodiment 3

[0034] One side of the blanking plate 5 is connected to one side of the support frame 2. At the bottom end of the blanking plate 5, there are two support columns 501 connected to the top end of the first support plate 1, which are used to support the blanking plate 5;

[0035] The interior of the placement rack 6 is provided with a filter plate 601. The surface of the filter plate 601 is provided with filter holes for filtering the lubricating oil on the surface of the steel pipe. A oil collecting box 602 is slidably arranged at the bottom end of the placement rack 6 and below the filter plate 601 for collecting the lubricating oil. A chute is opened at the bottom end of the placement rack 6, and a slider is arranged at the bottom end of the oil collecting box 602. The slider is slidably connected to the chute, which is convenient for sliding the oil collecting box 602 and taking it out.

[0036] The buffer mechanism 7 includes an adjusting column 701, a second adjusting cylinder 702 and a connecting spring 703. The adjusting column 701 is arranged at the bottom end of the placement rack 6, and there are four adjusting columns 701. The second adjusting cylinder 702 is arranged at the top end of the first support plate 1 and is slidably connected to the adjusting column 701. The connecting spring 703 is arranged between the placement rack 6 and the first support plate 1, and the connecting spring 703 is sleeved outside the adjusting column 701 and the second adjusting cylinder 702. When the steel pipe falls into the placement rack 6, under the action of gravity, the adjusting column 701 will slide in the second adjusting cylinder 702, thereby squeezing the connecting spring 703, which can play a certain buffering role and reduce the impact force of the steel pipe on the placement rack 6.

[0037] During use, first adjust the height of the receiving chute 4 according to the height of the cold rolling mill to make it flush. Start the motor 1204, and the transmission shaft of the motor 1204 drives the driving bevel gear 1202 to rotate. Since the driving bevel gear 1202 is meshed with the driven bevel gear 1201, the driving bevel gear 1202 drives the driven bevel gear 1201 to rotate. The rotation of the driven bevel gear 1201 drives the threaded rod 10 to rotate, thereby driving the moving cylinder 11 to move. The movement of the moving cylinder 11 drives the first support plate 1 and the receiving chute 4 at its top end to move, so that the receiving chute 4 corresponds to the outlet of the cold rolling mill. The first support plate 1 drives the adjusting rod 101 to slide in the first adjusting cylinder 102, increasing the stability of the first support plate 1.

[0038] The steel plate is conveyed from the cold rolling mill into the receiving chute 4. Start the air cylinder 307. Under the action of the first rotating seat 303, the second rotating seat 306 and the tenth rotating seat 3010, the telescopic end of the air cylinder 307 drives the receiving chute 4 to rotate a certain angle, so that the receiving chute 4 is connected with the blanking plate 5. Under the action of gravity, the steel pipe is conveyed along the blanking plate 5 into the placement rack 6. The lubricating oil attached to the steel pipe is filtered into the oil collecting box 602 through the filter plate 601. When the steel pipe falls into the placement rack 6, under the action of gravity, the adjusting column 701 will slide in the second adjusting cylinder 702, thereby squeezing the connecting spring 703, which can play a certain buffering role and reduce the impact force of the steel pipe on the placement rack 6.

[0039] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
