Description

Technical Field

[0001] This utility model relates to the field of welded pipe processing, and in particular to a welded pipe processing device capable of cutting to a fixed length. Background Technology

[0002] Welded steel pipes, also known as welded tubes, are steel pipes made by rolling and welding steel plates or strips. They are typically available in 6-meter lengths. The production process for welded steel pipes is simple, efficient, and offers a wide variety of specifications with low equipment investment. However, their strength is generally lower than that of seamless steel pipes. Straight seam welded pipes, on the other hand, have a simple production process, high efficiency, low cost, and have seen rapid development. Spiral welded pipes generally have higher strength than straight seam welded pipes, and can be produced from narrower blanks to create larger diameter pipes, or from blanks of the same width to create pipes of different diameters. During production, the welded pipes also need to be cut to the required length.

[0003] Commonly available welded pipe processing equipment requires workers to measure the required length on the surface of the welded pipe with a ruler before cutting. This method is not very precise, and the position of the grinding wheel needs to be aligned with the position of the drawing line during the cutting process after drawing the line, which is inconvenient and reduces the working efficiency of the equipment.

[0004] In order to ensure that the cutting length is the same each time, the commonly used welded pipe processing equipment on the market needs to place the cut section of the welded pipe after cutting it, and make sure that one end of the cut section is in contact with the predetermined initial position before cutting. However, it is quite laborious to move the welded pipe and there is also a risk of touching the grinding wheel, which reduces the working efficiency of the equipment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a welded pipe processing device capable of fixed-length cutting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a welded pipe processing device capable of fixed-length cutting, comprising a base, the base including a bottom plate, a top plate fixedly connected to the upper surface of the base, a first groove formed on the lower surface of the top plate, a clamping mechanism installed on the inner wall of the first groove, the clamping mechanism including a slider, the surface of the slider being movably connected to the inner wall of the first groove, a first electric telescopic rod fixedly connected to the lower surface of the slider, a connecting ring movably connected to the end of the first electric telescopic rod, an anti-slip layer fixedly connected to the inner wall of the connecting ring, a torsion spring installed on the surface of the connecting ring, a connecting block fixedly connected to the surface of the connecting ring, a first cylinder fixedly connected to the right side surface of the connecting block, and one end of the first cylinder fixedly connected to the surface of the base.

[0007] As a further description of the above technical solution:

[0008] An auxiliary mechanism is installed on the lower surface of the top plate. The auxiliary mechanism includes a connecting rod. One end of the connecting rod is fixedly connected to the lower surface of the top plate. The end of the connecting rod is movably connected to a first rotating shaft. A roller is fixedly connected to the surface of the first rotating shaft, and a first gear is fixedly connected to the surface of the first rotating shaft.

[0009] As a further description of the above technical solution:

[0010] A limiting mechanism is installed on the lower surface of the top plate. The limiting mechanism includes a second electric telescopic rod. One end of the second electric telescopic rod is fixedly connected to the lower surface of the top plate. The second electric telescopic rod is located on the right side of the connecting rod. A baffle is fixedly connected to the end of the second electric telescopic rod.

[0011] As a further description of the above technical solution:

[0012] A cutting mechanism is installed on the upper surface of the base. The cutting mechanism includes a movable plate. The bottom of the movable plate is movably connected to the upper surface of the base. A second cylinder is fixedly connected to the back of the movable plate. One end of the second cylinder is fixedly connected to the surface of the base.

[0013] As a further description of the above technical solution:

[0014] A motor is fixedly connected to the upper surface of the second cylinder, and a second rotating shaft is fixedly connected to the output end of the motor. A first helical gear is fixedly connected to the surface of the second rotating shaft, and a grinding wheel is fixedly connected to the surface of the second rotating shaft. The grinding wheel is located to the right of the first helical gear.

[0015] As a further description of the above technical solution:

[0016] A connecting mechanism is installed on the surface of the base. The connecting mechanism includes a third rotating shaft. One end of the third rotating shaft is movably connected to the surface of the base. A second gear is fixedly connected to the surface of the third rotating shaft. A second helical gear is fixedly connected to the surface of the third rotating shaft. The end of the second helical gear meshes with the end of the grinding wheel. The end of the second gear meshes with the end of the first gear.

[0017] The utility model has the following beneficial effects:

[0018] 1. Compared with existing technologies, this welded pipe processing device capable of fixed-length cutting utilizes a first electric telescopic rod, a connecting ring, a torsion spring, and a first cylinder. During operation, activating the first electric telescopic rod causes it to retract, pulling the connecting ring at its end upwards, thus increasing its inner diameter. Then, activating the first cylinder moves it to the left, and once in the desired position, activating the first electric telescopic rod again extends it. The connecting ring at its end then clamps the welded pipe placed inside it under the action of the surface torsion spring. At this point, activating the first cylinder allows it to retract, thus cutting off one end of the welded pipe clamped by the connecting ring. Once the end is moved to a position where it fits against the left side surface of the baffle, the cutting mechanism can be activated to cut the welded pipe. Compared to conventional devices, which require arranging the cut section of the welded pipe after each cut and ensuring that one end of the cut section is in contact with the predetermined initial position before cutting, this device can move the subsequent steel pipe forward to the set position accurately after the previous section of steel pipe has been cut, greatly improving the efficiency of the device.

[0019] 2. Compared with the prior art, this welded pipe processing device capable of fixed-length cutting utilizes a first helical gear, a second gear, and a third helical gear. During operation, when the motor is started, the second shaft fixed at the motor output end rotates, driving the first helical gear fixed on the surface of the second shaft to rotate. The second helical gear, meshing with the end of the first helical gear, also drives the third shaft fixedly connected to the inner wall of the second helical gear to rotate. The surface of the third shaft is also fixed with a second gear, which drives the first gear meshing with it to rotate, ultimately driving the first shaft fixed on the inner wall of the first gear to rotate. This causes the roller fixed on the surface of the first shaft to rotate. The roller is located on the surface of the welded pipe, and the rotation of the roller helps to accelerate the speed at which the clamping mechanism moves the welded pipe toward the limiting mechanism. When cutting is required, the first helical gear on the second shaft disengages from the second helical gear, and the roller naturally stops rotating, thus not affecting the position of the welded pipe.

[0026] Reference Figure 1-4 This utility model provides a welded pipe processing device capable of fixed-length cutting: It includes a base 1, which includes a base 101. A top plate 102 is fixedly connected to the upper surface of the base 101. A first groove 103 is formed on the lower surface of the top plate 102. A clamping mechanism 2 is installed on the inner wall of the first groove 103. The clamping mechanism 2 includes a slider 201.

A connecting ring 203 is movably connected to the end of the first electric telescopic rod 202. An anti-slip layer 204 is fixedly connected to the inner wall of the connecting ring 203. A torsion spring 205 is installed on the surface of the connecting ring 203. A connecting block 206 is fixedly connected to the surface of the connecting ring 203. A first cylinder is fixedly connected to the right side surface of the connecting block 206. 207. One end of the first cylinder 207 is fixedly connected to the surface of the base 101. The first electric telescopic rod 202 is activated, and the first electric telescopic rod 202 retracts, pulling up the connecting ring 203 installed at the end of the first electric telescopic rod 202, so that the inner diameter of the connecting ring 203 increases. Then the first cylinder 207 is activated to move to the left. After moving to the appropriate position, the first electric telescopic rod 202 is activated again, so that the first electric telescopic rod 202 extends. The connecting ring 203 at the end of the first electric telescopic rod 202 can clamp the welded pipe placed inside it under the action of the surface torsion spring 205. At this time, the first cylinder 207 can be activated to retract, so that one end of the welded pipe clamped by the connecting ring 203 moves to a position that fits against the left side surface of the baffle 402. Then the cutting mechanism 5 can be activated to cut the welded pipe.

[0027] An auxiliary mechanism 3 is installed on the lower surface of the top plate 102. The auxiliary mechanism 3 includes a connecting rod 301. One end of the connecting rod 301 is fixedly connected to the lower surface of the top plate 102, and the end of the connecting rod 301 is movably connected to a first rotating shaft 302. A roller 303 is fixedly connected to the surface of the first rotating shaft 302, and a first gear 304 is fixedly connected to the surface of the first rotating shaft 302. A limiting mechanism 4 is installed on the lower surface of the top plate 102. The limiting mechanism 4 includes a second electric telescopic rod 401. One end of the second electric telescopic rod 401 is fixedly connected to the lower surface of the top plate 102. The second electric telescopic rod 401 is located to the right of the connecting rod 301, and the end of the second electric telescopic rod 401 is fixedly connected to a baffle 402. A cutting mechanism 5 is installed on the upper surface of the base 101. The cutting mechanism 5 includes a moving plate 501. The bottom of the movable plate 501 is movably connected to the upper surface of the base 101. A second cylinder 502 is fixedly connected to the back of the movable plate 501. One end of the second cylinder 502 is fixedly connected to the surface of the base 101. A motor 503 is fixedly connected to the upper surface of the second cylinder 502. A second rotating shaft 504 is fixedly connected to the output end of the motor 503. A first helical gear 505 is fixedly connected to the surface of the second rotating shaft 504. A grinding wheel 506 is fixedly connected to the surface of the second rotating shaft 504, and the grinding wheel 506 is located to the right of the first helical gear 505. A connecting mechanism 6 is installed on the surface of the base 101. The connecting mechanism 6 includes a third rotating shaft 601. One end of the third rotating shaft 601 is movably connected to the surface of the base 101. A second gear 602 is fixedly connected to the surface of the third rotating shaft 601, and a second helical gear 603 is fixedly connected to the surface of the third rotating shaft 601. The end of the second helical gear 603 meshes with the end of the grinding wheel 506, and the end of the second gear 602 meshes with the end of the first gear 304. When the motor 503 is started, the second rotating shaft 504, which is fixed at the output end of the motor 503, rotates, driving the first helical gear 505, which is fixed to the surface of the second rotating shaft 504, to rotate. The second helical gear 603, which meshes with the end of the first helical gear 505, also drives the third rotating shaft 601, which is fixedly connected to the inner wall of the second helical gear 603, to rotate. The surface of the third rotating shaft 601 is also fixed with a second gear 602, which drives the first gear 304, which meshes with it, to rotate. The rotation eventually drives the first rotating shaft 302 fixed to the inner wall of the first gear 304 to rotate, which causes the roller 303 fixed to the surface of the first rotating shaft 302 to rotate. The roller 303 is located on the surface of the welded pipe. The rotation of the roller 303 can help speed up the clamping mechanism 2 to move the welded pipe towards the limiting mechanism 4. When cutting is required, the first helical gear 505 on the second rotating shaft 504 disengages from the second helical gear 603, and the roller 303 will naturally stop rotating and will not affect the position of the welded pipe.

[0028] Working principle: When the first electric telescopic rod 202 is activated, it retracts, pulling upwards the connecting ring 203 at its end, increasing its inner diameter. Then, the first cylinder 207 moves to the left. Once in the desired position, the first electric telescopic rod 202 is activated again, extending it. The connecting ring 203 at its end, under the action of the surface torsion spring 205, clamps the welded pipe placed inside. At this point, the first cylinder 207 retracts, clamping the pipe by the connecting ring 203. Once one end of the welded pipe is moved to a position where it is in contact with the left side surface of the baffle 402, the cutting mechanism 5 can be activated to cut the welded pipe. The motor 503 is then started, and the second rotating shaft 504, fixed at the output end of the motor 503, rotates, driving the first helical gear 505, fixed to the surface of the second rotating shaft 504, to rotate. The second helical gear 603, meshing with the end of the first helical gear 505, also drives the third rotating shaft 601, fixedly connected to the inner wall of the second helical gear 603, to rotate. A second gear 602 is also fixed to the surface of the third rotating shaft 601, and the second gear 602 drives the first gear 304, which meshes with it. The rotation eventually drives the first rotating shaft 302 fixed to the inner wall of the first gear 304 to rotate, which causes the roller 303 fixed to the surface of the first rotating shaft 302 to rotate. The roller 303 is located on the surface of the welded pipe. The rotation of the roller 303 can help speed up the clamping mechanism 2 to move the welded pipe towards the limiting mechanism 4. When cutting is required, the first helical gear 505 on the second rotating shaft 504 disengages from the second helical gear 603, and the roller 303 will naturally stop rotating and will not affect the position of the welded pipe.
