Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipes, specifically to a composite seamless steel pipe preparation equipment for high corrosion-resistant heat exchangers. Background Technology

[0002] Seamless steel pipes are made by piercing a whole round steel bar and have no weld seams on the surface. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and jacking pipes, etc.

[0003] Seamless steel pipes need to be cut into appropriate lengths during processing. The process involves fixing the main body before cutting, then releasing the fixation, moving the main body until the desired length is reached, fixing it again, and then cutting again. This process is repeated until the main body is cut into several appropriate lengths. This frequent fixing and releasing is time-consuming and labor-intensive, greatly reducing the cutting efficiency of seamless steel pipes. Therefore, a device is urgently needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a manufacturing equipment for composite seamless steel pipes for high corrosion-resistant heat exchangers, so as to solve the problems mentioned in the background art.

In use, the steel pipe is fixed to the movable frame by the fixing mechanism, and then the first motor is started, the first motor drives the first screw to rotate, causing the movable plate to move along the first screw, and driving the movable frame to move along the inside of the first sliding groove, thereby facilitating the movement of the steel pipe. After fixing, the cutting length is adjusted by moving the movable frame, eliminating the need for multiple unfixing and refixing, greatly improving the cutting efficiency.

[0006] Preferably, the support mechanism includes a column, a fixing ring, and a roller. The column is fixed at the top of the base plate, the fixing ring is fixed at the top of the column, and the roller is installed at the bottom of the fixing ring via a wheel axle. In use, the steel pipe is passed through the inside of the fixing ring, with the lower end of the steel pipe tightly against the top of the roller. Then, when the steel pipe moves, the roller assists in moving the steel pipe to prevent the outer surface of the steel pipe from being damaged by scratches.

[0007] Preferably, the fixing mechanism includes a second slide groove, a second motor, a second screw, a slider, and a clamping block. The second slide groove is located at the center of the top of the movable frame. The second motor is fixed to one side of the movable frame. The second screw is fixed at the output end of the second motor. The slider is threaded onto the outside of the second screw. The clamping block is fixed at the top of the slider. In use, the steel pipe is passed through the clamping block, and then the second motor is started. The second motor drives the second screw to rotate, causing the slider to move along the inside of the second slide groove, which in turn moves the clamping block until the steel pipe is clamped and fixed, thus facilitating subsequent processing.

[0008] Preferably, there are two first grooves, which are symmetrically located on both sides of the top of the base plate.

[0009] Preferably, the top of the slider extends movably into the interior of the second groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. In use, the steel pipe is fixed to the movable frame by a fixing mechanism. Then, the first motor is started, and the first motor drives the first screw to rotate, so that the movable plate moves along the first screw and drives the movable frame to move along the inside of the first slide groove, thereby facilitating the movement of the steel pipe. After the fixing is completed, the cutting length is adjusted by moving the movable frame. There is no need to repeatedly unfix and fix it, which greatly improves the cutting efficiency. 2. In use, the steel pipe is passed through the inside of the fixing ring, with the lower end of the steel pipe tightly attached to the top of the roller.

[0016] Please see Figure 1-3 This utility model provides a device for preparing composite seamless steel pipes for high corrosion-resistant heat exchangers, including a base plate 1. Two first sliding grooves 2 are symmetrically located on either side of the top of the base plate 1. A movable frame 4 slides inside the first sliding groove 2. The top of the movable frame 4 has a fixing mechanism for easily fixing the steel pipe. The top of the base plate 1 has a support mechanism for easily supporting the steel pipe. A first motor 3 is fixed to one side of the base plate 1 via a mounting bracket. A first screw 5 is fixed to the output end of the first motor 3 via a coupling. A movable plate 6 is threadedly connected to the outside of the first screw 5. The bottom of the movable frame 4 is fixed to the movable plate 6 with bolts. The movable plate 6 slides on both sides of the base plate 1. In use, the steel pipe is fixed to the movable frame 4 via the fixing mechanism. Then, the first motor 3 is started, driving the first screw 5 to rotate, causing the movable plate 6 to move along the first screw 5, which in turn moves the movable frame 4 along the inside of the first sliding groove 2, thus facilitating the movement of the steel pipe. After fixing, the cutting length is adjusted by moving the movable frame 4, eliminating the need for multiple unfixing and refixing, greatly improving cutting efficiency.

[0017] The support mechanism includes a column 7, a fixing ring 8, and a roller 9. The column 7 is fixed to the top of the base plate 1 by bolts. The fixing ring 8 is welded and fixed to the top of the column 7. The roller 9 is installed at the bottom of the fixing ring 8 through a wheel axle. When in use, the steel pipe is passed through the inside of the fixing ring 8, and the lower end of the steel pipe is close to the top of the roller 9. Then, when the steel pipe moves, the roller 9 assists in the movement of the steel pipe to prevent the outer surface of the steel pipe from being damaged by scratches.

[0018] The fixing mechanism includes a second slide groove 10, a second motor 12, a second screw 13, a slider 14, and a clamping block 11.

The second screw 13 is fixed to the output end of the second motor 12 by a coupling. The slider 14 is threaded onto the outside of the second screw 13, and the top of the slider 14 extends movably into the interior of the second slide groove 10. The second screw 13 is a positive and negative screw. The clamping block 11 is fixed to the top of the slider 14 by bolts. In use, the steel pipe is passed through the clamping blocks 11, and then the second motor 12 is started. The second motor 12 drives the second screw 13 to rotate, causing the slider 14 to move along the interior of the second slide groove 10, which in turn moves the clamping block 11 until the steel pipe is clamped and fixed, thus facilitating subsequent processing.

[0019] Working principle: During use, the steel pipe is fixed to the movable frame 4 by the fixing mechanism. Then, the first motor 3 is started, which drives the first screw 5 to rotate, causing the movable plate 6 to move along the first screw 5. This moves the movable frame 4 along the inside of the first slide groove 2, thus facilitating the movement of the steel pipe. After fixing, the cutting length is adjusted by moving the movable frame 4, eliminating the need for multiple unfixing and refixing, greatly improving cutting efficiency. During use, the steel pipe is passed through the inside of the fixing ring 8, with the lower end of the steel pipe tightly against the top of the roller 9. When the steel pipe moves, the roller 9 assists in its movement, preventing damage to the outer surface of the steel pipe due to scratches.
