Description

Technical Field

[0001] The utility model relates to the technical field of threaded pipe machining, in particular to a cutting device for threaded pipe production. Background Art

[0002] Threaded pipes, also known as low-rib pipes, are mainly used to expand the heat transfer area by ribbed pipes (ribbed coefficient is 2-3) and are generally used in situations where the heat transfer coefficient inside the pipe is more than 1 times greater than the heat transfer coefficient outside the pipe. Due to the surface tension, condensation and boiling outside the pipe also have a good strengthening effect. The processing methods of threaded pipes generally include twisting method, rolling method, extrusion method and rolling method. They are usually used to process threaded pipes with large diameters and thick walls. Cutting devices are required during the processing of threaded pipes.

This cutting method is not only labor-intensive, but also the iron filings generated during cutting may splash onto the user, posing certain safety hazards. In addition, if the user's hand shakes during the cutting process, the cutting surface will be tilted, thereby causing the threaded pipe to be cut obliquely, affecting its cutting effect.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0030] Embodiment 1:

[0031] A cutting device for producing threaded pipes, comprising a workbench 1 and a cutting machine 2, wherein the cutting machine 2 is fixedly mounted on the top of the workbench 1, and a pushing mechanism is provided on the top of the workbench 1, which can electrically push the threaded pipe, thereby improving the cutting effect of the cutting machine 2;

[0032] The pushing mechanism includes a fixed plate 3 fixedly connected to the top of the workbench 1, an electric telescopic rod 4 is fixedly installed on one side of the fixed plate 3, a moving frame 5 is fixedly connected to the output end of the electric telescopic rod 4, a connecting column 6 is provided on one side of the moving frame 5, a supporting plate 7 is fixedly connected to one side of the connecting column 6, a placement groove 8 is provided on the top of the supporting plate 7, and a clamping mechanism is provided on the top of the workbench 1, which can play a role in clamping and fixing the threaded pipe on the supporting plate 7;

[0033] In this embodiment, by providing a pushing mechanism, when the user needs to cut the threaded pipe, the user can manually place the threaded steel pipe in the placement groove 8, and then start the electric telescopic rod 4, the electric telescopic rod 4 moves to drive the moving frame 5 and the limit block 23 to move along the trajectory of the limit groove 24, and at the same time, it will drive the moving block 12, the connecting column 6, the support plate 7 and the threaded pipe in the placement groove 8 to move closer to the cutting knife position of the cutting machine 2, until the cutting machine 2 moves to completely cut off the threaded pipe, and then the electric telescopic rod 4 can be closed, which effectively avoids the phenomenon that the iron chips splashed during cutting cause damage to the user's arm;

[0034] The invention solves the problem that the existing threaded pipe cutting device cuts the threaded pipe by holding the threaded pipe with both hands and sending it under the cutting knife for cutting. This cutting method is not only labor-intensive, but also the iron filings generated during cutting may splash to the user, which poses certain safety hazards. In addition, if the user's hand shakes during the cutting process, the cutting surface will be tilted, thereby causing the threaded pipe to be cut obliquely, affecting the quality of the finished product.

[0035] Two limit blocks 23 are fixedly connected to the bottom of the moving frame 5, and a limit slot 24 used in conjunction with the limit blocks 23 is provided on the top of the workbench 1;

[0036] By providing the limiting block 23 and the limiting groove 24 , the limiting block 23 can be driven to move along the track of the limiting groove 24 when the moving frame 5 moves, thereby limiting the moving track of the moving frame 5 .

[0037] Embodiment 2:

[0038] On the basis of the first embodiment, the first embodiment provides a pushing mechanism, which can electrically push the threaded tube, thereby improving the cutting effect of the cutting machine 2. However, this mechanism does not have the function of clamping and fixing the threaded tube in the placement groove 8. If it is shaken by external force during the cutting process, it will also cause cutting deviation, and only threaded tubes with fixed diameters can be cut. When it is necessary to cut a larger or smaller threaded tube, the threaded tube in the placement groove 8 will shake due to the gap during the cutting process, and if it is shaken by external force during the cutting process, it will also affect its cutting effect. The clamping mechanism in the present application includes two rotating blocks 9 arranged on one side of the support plate 7, and a threaded rod 10 is fixedly connected to one side of the rotating block 9. One end of the threaded rod 10 passes through the interior of the placement groove 8. Two clamping plates 11 are arranged inside the placement groove 8. An adjustment mechanism is arranged on the top of the movable frame 5, which can adjust the position of the clamping mechanism.

[0039] The present invention is provided with a clamping mechanism, and the user can manually rotate the rotating block 9 while pushing the mechanism, and the rotating block 9 is rotated to drive the threaded rod 10 to rotate around the bearing 21, and the external thread on the surface of the threaded rod 10 squeezes the internal thread inside the threaded hole 22, so that the threaded rod 10 drives the clamping plate 11 and the anti-slip plate 20 to approach the surface of the threaded rod 10 in the placement groove 8 until they are in close contact with the surface of the threaded tube, so as to play a role in fixing it, which not only effectively prevents the occurrence of shaking caused by external force during the cutting process, resulting in cutting deviation, but also further improves the practicality of this device;

[0040] The problem that the pusher does not have the function of clamping and fixing the threaded tube in the placement groove 8, and if it is shaken by external force during the cutting process, it will also cause the cutting to be off-center, and only threaded tubes with fixed diameters can be cut. When it is necessary to cut larger or smaller threaded tubes, the threaded tube in the placement groove 8 will shake due to the gap during the cutting process, and if it is shaken by external force during the cutting process, it will also affect the cutting effect.

[0041] One side of the clamping plate 11 is fixedly connected to the anti-slip plate 20, and one side of the clamping plate 11 and the anti-slip plate 20 are both arc-shaped;

[0042] By arranging the anti-slip plate 20 and the clamping plate 11 and one side of the anti-slip plate 20 to be arc-shaped, the contact area and friction force between the clamping plate 11 and the threaded pipe can be increased, thereby further improving the clamping effect of the clamping mechanism.

[0043] The support plate 7 has threaded holes 22 on both sides, and the threaded holes 22 are used in conjunction with the threaded rods 10;

[0044] By providing the threaded hole 22 , the internal thread inside the threaded hole 22 can be squeezed by the external thread on the surface of the threaded rod 10 , so that the threaded rod 10 and the clamping plate 11 drive the anti-slip plate 20 to move.

[0045] A bearing 21 is provided at one end of the threaded rod 10, and one end of the threaded rod 10 is rotatably connected to one side of the clamping plate 11 through the bearing 21;

[0046] By providing the bearing 21, the stability of the threaded rod 10 can be improved, and the smoothness of the threaded rod 10 during rotation can be improved.

[0047] Embodiment three:

[0048] On the basis of the second embodiment, the clamping mechanism in the second embodiment can play the role of clamping and fixing the threaded tube on the support plate 7, but this mechanism does not have the function of adjusting the clamping plate 11, and the threaded tube needs to be cut into tubes of different lengths during the production process. When the steel tube needs to be cut to a longer length, the tail of the threaded tube vibrates during cutting, and the clamping mechanism does not have the function of clamping its tail position, which also affects its cutting effect. The adjustment mechanism in the present application includes a plurality of moving blocks 12 movably connected to the surface of the moving frame 5, one side of the moving block 12 is fixedly connected to one end of the connecting column 6, the top of the moving block 12 is fixedly connected to a support frame 13, the top of the support frame 13 is provided with a pull-out plate 14, the bottom of the pull-out plate 14 is fixedly connected to two pull-out columns 15, and the top of the moving frame 5 is provided with a plurality of cylindrical holes 17;

[0049] Two plug holes 16 are provided on the top of the moving block 12. One end of the pull-out column 15 passes through the cylindrical hole 17 and is fixedly connected with a plug block 18. The plug block 18 is used in conjunction with the plug hole 16. A spring 19 is fixedly connected to the top of the plug block 18. One end of the spring 19 away from the plug block 18 is fixedly connected to the bottom of the support frame 13.

[0050] In this embodiment, by providing an adjustment mechanism, the pull-out plate 14 can be manually pulled out while the pushing mechanism and the clamping mechanism are in use. At this time, the spring 19 is in a stretched state, and the pull-out plate 14 can drive the pull-out column 15 and the plug-in block 18 to pass through the cylindrical hole 17 and disengage from the inside of the plug-in hole 16 through the elastic force generated by the spring 19. At this time, the moving block 12 can be pushed, and the moving block 12 will drive the connecting column 6, the support plate 7 and the clamping mechanism to move along the moving frame 5 and the threaded rod 10 until it moves to the length of the threaded pipe that needs to be cut;

[0051] The user can then loosen the pull-out plate 14, and the elastic force produced by the spring 19 can drive the pull-out column 15 and the plug-in block 18 to be plugged into the plug-in hole 16, so that the position of the moving block 12 can be fixed. At this time, the surface of the threaded tube can be fixed by using the clamping mechanism, and then the pushing mechanism can be started to push the threaded tube to cut it;

[0052] The problem that the clamping mechanism does not have the function of adjusting the clamping plate 11 is solved. The threaded pipe needs to be cut into pipes of different lengths during the production process. When a long steel pipe needs to be cut, the tail of the threaded pipe vibrates during cutting, but the clamping mechanism does not have the function of clamping the tail position, which also affects the cutting effect.

[0053] Working principle: When the user needs to cut the threaded pipe, the user can manually place the threaded pipe in the placement slot 8, and then start the electric telescopic rod 4, which drives the moving frame 5 and the limit block 23 to move along the trajectory of the limit slot 24, and at the same time drives the moving block 12, the connecting column 6, the support plate 7 and the threaded pipe in the placement slot 8 to move closer to the cutting knife position of the cutting machine 2, until the cutting machine 2 completely cuts off the threaded pipe, and then close the electric telescopic rod 4, which effectively avoids the phenomenon that the iron chips splashed during cutting cause damage to the user's arm;

[0054] When the user pushes the mechanism, the rotating block 9 is manually rotated, and the rotating block 9 drives the threaded rod 10 to rotate around the bearing 21, and the external thread on the surface of the threaded rod 10 squeezes the internal thread inside the threaded hole 22, so that the threaded rod 10 drives the clamping plate 11 and the anti-slip plate 20 to approach the surface of the threaded rod 10 in the placement groove 8 until they are in close contact with the surface of the threaded tube, thereby being able to play a role in fixing it, which not only effectively prevents the occurrence of shaking caused by external force during the cutting process, resulting in cutting deviation, but also further improves the practicality of this device;

[0055] When it is necessary to cut threaded tubes of different lengths, the pull-out plate 14 is manually pulled out. At this time, the spring 19 is in a stretched state, and the elastic force generated by the spring 19 can enable the pull-out plate 14 to drive the pull-out column 15 and the plug-in block 18 to pass through the cylindrical hole 17 and disengage from the inside of the plug-in hole 16. At this time, the moving block 12 can be pushed, and the moving block 12 will drive the connecting column 6, the support plate 7 and the clamping mechanism to move along the moving frame 5 and the threaded rod 10 until it moves to the length of the threaded tube that needs to be cut. The user can then loosen the pull-out plate 14, and the elastic force generated by the spring 19 can drive the pull-out column 15 and the pull-out block to be plugged into the plug-in hole 16, so that the position of the moving block 12 can be fixed. At this time, the surface of the threaded tube can be fixed by using the clamping mechanism, and then the pushing mechanism is started to push the threaded tube to cut it.

[0056] It should be noted that the electric telescopic rod 4 and the cutting machine 2 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. The specific composition and principle of the power supply of the electric telescopic rod 4 and the cutting machine 2 are clear to those skilled in the art, so they will not be described in detail.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
