Description

Technical Field

[0001] The utility model relates to the technical field of steel pipes, and more specifically to a cold-rolled precision steel pipe cutting device. Background Art

[0002] Cold-rolled precision seamless steel pipe is a seamless steel pipe with high dimensional accuracy and good surface finish used for precision mechanical structures, hydraulic equipment or steel sleeves. The main cold processing methods of steel pipes are cold drawing and cold rolling. In recent years, with the development of science and technology, a cold spinning method has been developed. This method can produce large-diameter, high-precision cold-rolled pipes and variable-section cold-rolled pipes. When cutting cold-pressed precision steel pipes, a cutting device is required.

[0003] When using, the existing cold-pressed precision steel pipe cutting device can only cut a single steel pipe at a time. The staff needs to load a single steel pipe and then cut it individually, which will affect the cutting efficiency of the steel pipe. At the same time, since a single steel pipe is cut each time, only a single steel pipe can be fixed each time it is cut, which is time-consuming and labor-intensive to operate and increases work intensity.

[0004] In view of this, we propose a cold-rolled precision steel pipe cutting device. Utility Model Content

[0028] See also Figure 1-5 ,The utility model provides a technical solution:

[0029] A cold-rolled precision steel pipe cutting device includes a body 1, a fixed frame 2 is fixedly provided on the upper side of the body 1, a threaded rod 3 is rotatably provided inside the fixed frame 2, and a support plate 4 is movably provided on the upper side of the fixed frame 2, two sections of threads in opposite directions are provided on the outer side of the threaded rod 3, and thread blocks 5 are sleeved on the two sections of threads in opposite directions on the outer side of the threaded rod 3, and support blocks 6 for docking with the support plate 4 are rotatably provided on the upper sides of the two groups of thread blocks 5, two groups of L-shaped blocks 11 are fixed on the upper side of the body 1, and the two groups of L-shaped blocks 11 are fixed between them. A top plate 12 is provided, and a plurality of groups of arc blocks 13 are fixedly provided on the lower side of the top plate 12 and the upper side of the support plate 4. A motor 9 is fixedly provided on the outside of the fixed frame 2, and the power end of the motor 9 movably passes through the fixed frame 2 and is fixedly connected to the threaded rod 3. A fixing frame 18 is fixedly provided on the outside of the machine body 1, and a cutting mechanism 22 is movably provided on the inside of the fixing frame 18. The cutting mechanism 22 is mainly composed of a mounting frame, a rotating rod, a cutting wheel, and a cutting motor. Turning on the power supply of the cutting motor can drive the cutting wheel to rotate, thereby facilitating the cutting of the steel pipe.

[0030] Specifically, a limit block 7 is rotatably provided on the upper side of the support block 6, and a limit groove 8 for docking with the limit block 7 is opened on the lower side of the support plate 4. When the support plate 4 moves up and down, it can drive the limit block 7 to slide in the limit groove 8 to ensure the normal up and down movement of the support plate 4.

[0031] Furthermore, two sets of sliding grooves 10 for docking the threaded block 5 are opened on the inner side of the fixed frame 2. The sliding grooves 10 can limit the threaded block 5, so that when the threaded rod 3 rotates, the threaded block 5 can be driven to move parallel to the threaded rod 3, thereby improving the movement stability of the threaded block 5.

[0032] It is worth noting that an anti-skid pad 14 is fixedly provided on the outside of the arc block 13. The anti-skid pad 14 can improve the friction of the arc block 13, thereby improving the fixing effect on the steel pipe and preventing the steel pipe from slipping.

[0033] It is worth noting that a mounting frame 15 is fixedly provided on the outside of the body 1, and a first electric push rod 16 is provided on the inside of the mounting frame 15. One end of the first electric push rod 16 is connected to the mounting frame 15, and a push plate 17 is provided on the other end of the first electric push rod 16. By turning on the first electric push rod 16 through an external power supply, the support plate 17 can be easily driven to move, thereby facilitating the movement of multiple groups of steel pipes, further improving the convenience of cutting multiple groups of steel pipes.

[0034] In addition, a mounting frame 19 is movably provided on the inner side of the fixing frame 18, a mounting block 20 is movably provided on the inner side of the mounting frame 19, a connecting block 21 is fixedly provided on the lower side of the mounting block 20, a cutting mechanism 22 is provided on the lower side of the connecting block 21, and a third electric push rod 24 is provided on the inner side of the mounting frame 19, one end of the third electric push rod 24 is connected to the inner side of the mounting frame 19, and the other end of the third electric push rod 24 is connected to the mounting block 20. By turning on the third electric push rod 24 through an external power supply, the cutting mechanism 22 can be conveniently driven to move horizontally, thereby facilitating the cutting of different steel pipes.

[0035] It must be said that a second electric push rod 23 is provided on the inner side of the fixing frame 18, one end of the second electric push rod 23 is connected to the fixing frame 18, and the other end of the second electric push rod 23 is connected to the mounting frame 19. By turning on the second electric push rod 23 through an external power supply, the cutting mechanism 22 can be easily driven to move up and down to ensure the cutting effect of the steel pipe.

[0036] Working principle: First, multiple groups of steel pipes are placed into the arc block 13 on the upper side of the support plate 4 in turn, and then the motor 9 is turned on by an external power supply. The motor 9 drives the threaded rod 3 to rotate, and the two groups of threaded blocks 5 arranged on the outside of the threaded rod 3 move simultaneously along the threaded rod 3 under the limiting action of the slide groove 10, and the distance between them is getting closer and closer. When the threaded block 5 moves, it drives the support block 6 to move, and the support plate 4 is pushed upward by the support block 6 until the upper side of the steel pipe is tightly against the arc block 13 on the lower side of the top plate 12, so that the steel pipe can be firmly clamped. Then, the cutting mechanism 22 and the second electric push rod 23 are turned on by an external power supply, and the second electric push rod 23 drives the cutting mechanism 22 to move downward to cut the steel pipe. At the same time, by turning on the third electric push rod 24, the cutting mechanism 22 can be driven to move horizontally, thereby facilitating the cutting of multiple groups of steel pipes and greatly improving the cutting efficiency of the steel pipe.
