Description

Technical Field

[0001] The invention relates to the technical field of straight seam welded pipe squaring, in particular to a straight seam welded pipe squaring device. Background Art

[0002] During the production process of straight seam welded round pipes, scrap pipes will be generated due to changes in specifications, roller changes, shunting, equipment failure, etc. These scrap pipes cannot enter the market due to various defects and are recycled as scrap steel. At the same time, during the packaging process of straight seam welded pipes, each package requires two pads at the bottom of the entire package of pipes. In this way, each package of pipes has pads as support during the stacking process, and there is a gap in the middle for easy hanging. The finished square pipes are now cut and used as pads.

[0003] Therefore, in the existing straight seam welded round pipe production process, scrap pipes will be generated due to specification changes, roller changes and adjustment, equipment failure, etc. These scrap pipes cannot enter the market due to various defects and cannot be secondary processed for subsequent use, resulting in a waste of resources. In addition, the height adjustment dimensions of multiple positions cannot be intuitively confirmed, resulting in poor accuracy. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that in the existing straight seam welded round pipe production process of the device, waste pipes will be generated due to specification changes, roller changes and shunting, equipment failure, etc. These waste pipes cannot enter the market due to various defects and cannot be secondary processed for subsequent use, resulting in waste of resources. In addition, the height adjustment dimensions of multiple positions cannot be intuitively confirmed, resulting in poor accuracy. A straight seam welded pipe pushing device is proposed.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A straight seam welded pipe pushing device is designed, which includes a base and a transmission box. A pipe pushing assembly is installed on the upper end of the base, and a motor is installed on one side of the transmission box. The output shaft of the motor is connected to multiple transmission shafts through a transmission structure inside the transmission box. The upper transmission shaft is movably connected to the front end notch of the transmission box. An indicator assembly is installed on the upper front side of the base in the pipe pushing assembly.

[0007] This setting is achieved by arranging a transmission box, a motor and a transmission shaft so that the height of the upper transmission shaft and the transmission structure inside the connected transmission box can be adjusted. The transmission structure and the transmission shaft can be linked through a Schmidt coupling to ensure that the transmission shaft can still achieve rotation transmission with the transmission structure inside the transmission box after the height changes.

[0008] Preferably, the push tube assembly includes a frame, and multiple frames are equidistantly fixed on the upper end of the base. The lower inner walls of the frames are fixedly connected to the lower bearing seats, and the upper inner walls of the frames are slidingly connected to the upper bearing seats. The upper inner wall of the upper bearing seat is threadedly connected to a roller adjusting bolt, and the outer wall of the roller adjusting bolt is rotatably connected to the frame. The interiors of the two groups of bearing seats on the left are rotatably connected to round rollers, and the interiors of the two groups of bearing seats on the right are rotatably connected to square rollers.

[0009] This setting is achieved by setting up the upper bearing seat and roller adjustment bolts, so that the user can rotate the roller adjustment bolts to drive the upper bearing seat to adjust the height through the roller adjustment bolts connected by threads, and then adjust the distance between the upper and lower round rollers and square rollers to adapt to the size changes of the pipe fittings.

[0010] Preferably, the inner walls of the upper round roller and the square roller are fixedly connected to the upper transmission shaft, and the inner walls of the lower round roller and the square roller are fixedly connected to the lower transmission shaft.

[0011] Preferably, the right end of the frame is fixedly connected to a base, the upper ends of the two groups of the bases on the left are rotatably connected to a plurality of circular guide rollers, and the upper ends of the two groups of the bases on the right are rotatably connected to a plurality of square guide rollers.

[0012] This setting is achieved by setting guide rollers so that the round guide rollers are used to drive the round pipes to be transported backwards, and the square guide rollers are used to drive the transport of the pipes after the square pipes are processed.

[0013] Preferably, inner walls of the round roller, square roller, round guide roller and square guide roller are fitted with pipe fittings.

[0014] Preferably, the upper end of the base is fixedly connected to the frame via a plurality of fixing bolts.

[0015] Preferably, the indicating assembly includes a through hole and a vertical plate, a plurality of the vertical plates are fixedly connected to the front side of the upper end of the base, a mark is processed above the front end of the vertical plate, and a plurality of the through holes are respectively processed above the front sides of the left and right ends of the frame, and a plurality of pointers are provided on the front side of the outer wall of the vertical plate, and the ends of the pointers are fixedly connected to the bearing seat above.

[0016] This setting is provided with a pointer at the front end of the vertical plate, so that the user can observe whether the pointers on both sides of the same vertical plate are at the same height, thereby ensuring the accuracy of height adjustment of multiple round rollers and square rollers during the adjustment process.

[0017] Preferably, the outer wall of the pointer passes through the inner wall of the through hole.

[0018] The invention provides a straight seam welded pipe pushing device, which has the following beneficial effects:

[0019] Through the cooperation among the motor, transmission box, round roller, square roller and pipe fitting, the motor can drive the transmission shaft to rotate through the transmission structure inside the transmission box, and then the transmission shafts of the upper and lower layers drive the round rollers and square rollers to rotate synchronously and in opposite directions, pushing the originally round pipe fittings gradually to the right, and under the extrusion of the square roller, the round pipe fittings are pushed into square pipe fittings, and the waste round pipes are pushed into square pipes, which are then cut at equal distances and used as pads for finished products. This effectively avoids the problem of waste pipes generated in the existing straight seam welded round pipe production process due to specification changes, roller changes, shunting, equipment failures, etc. These waste pipes cannot enter the market due to various defects and cannot be secondary processed for subsequent use, resulting in a waste of resources.

[0020] Through the coordination among the roller adjusting bolts, bearing seats, pointers, vertical plates, round rollers and square rollers, when the roller adjusting bolts are rotated and adjusted, the roller adjusting bolts of the same group on the front and rear sides need to be rotated at the same time. At the same time, when the height of the upper bearing seat changes, the pointer can be driven to adjust the height at the same time. When adjusting the height of the bearing seat at other positions, in order to ensure the consistency of the adjustment height, the user can observe whether the pointers on both sides of the same vertical plate are at the same height, thereby ensuring the accuracy of the height adjustment of multiple round rollers and square rollers during the adjustment process, avoiding the problem of poor accuracy caused by the inability to intuitively confirm the height adjustment dimensions of multiple positions in the existing technology.

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings:

[0031] Refer to the attached Figure 1-8 : In this embodiment, a straight seam welded pipe pushing device includes a base 1 and a transmission box 2. A push tube assembly 3 is installed on the upper end of the base 1, and a motor 7 is installed on one side of the transmission box 2. The model of the motor 7 can be determined according to the specific usage. The output shaft of the motor 7 is connected to multiple transmission shafts 6 through the transmission structure inside the transmission box 2. The upper transmission shaft 6 is movably connected to the front end notch of the transmission box 2. The upper transmission shaft 6 can be adjusted up and down in the notch of the transmission box 2, and the height between the upper transmission shaft and the connected transmission structure inside the transmission box 2 will also be adjusted accordingly. The transmission structure and the transmission shaft can be linked through a Schmidt coupling to ensure that the transmission shaft can still achieve rotation transmission with the transmission structure inside the transmission box 2 after the height change. An indication assembly 4 is installed on the upper front side of the base 304 in the push tube assembly 3.

[0032] Refer to the attached Figure 1-8 : In this embodiment, the tube pushing assembly 3 includes a frame 303, and multiple frames 303 are equidistantly fixed on the upper end of the base 1. The lower inner walls of the frames 303 are fixedly connected to the lower bearing seat 302, and the upper inner walls of the frames 303 are slidably connected to the upper bearing seat 302. The upper inner wall of the upper bearing seat 302 is threadedly connected to a roller adjusting bolt 305. By rotating the roller adjusting bolt 305, the upper bearing seat 302 can be driven to adjust its height up and down. The outer wall of the roller adjusting bolt 305 is rotatably connected to the frame 303. The interiors of the two groups of bearing seats 302 on the left are rotatably connected to round rollers 307, which are mainly used for conveying pipe fittings. The interiors of the two groups of bearing seats 302 on the right are rotatably connected to square rollers 301, which are mainly used for extruding pipe fittings to form square tubes.

[0033] The inner walls of the upper round roller 307 and the square roller 301 are fixedly connected to the upper transmission shaft 6, and the inner walls of the lower round roller 307 and the square roller 301 are fixedly connected to the lower transmission shaft 6. The right end of the frame 303 is fixedly connected to the base 304. The upper ends of the two groups of bases 304 on the left are rotatably connected with a plurality of round guide rollers 308. The round guide rollers 308 are used to drive the round pipe fittings to be transported backward. The upper ends of the two groups of bases 304 on the right are rotatably connected with a plurality of square guide rollers 306. The square guide rollers 306 are used to drive the transportation of the pipe fittings after the square pipe processing is completed. The inner walls of the round rollers 307, the square rollers 301, the round guide rollers 308 and the square guide rollers 306 are fitted with pipe fittings 5. The upper end of the base 1 is fixedly connected to the frame 303 by a plurality of fixing bolts 8.

[0034] Refer to the attached Figure 1-8 : In this embodiment, the indicating component 4 includes a through hole 401 and a vertical plate 404. Multiple vertical plates 404 are fixedly connected to the front side of the upper end of the base 304. A mark 403 is processed above the front end of the vertical plate 404. Multiple through holes 401 are respectively processed above the left and right front ends of the frame 303. Multiple pointers 402 are provided on the front side of the outer wall of the vertical plate 404. The adjustment height of the upper bearing seat 302 can be directly observed by coordinating the pointer 402 and the degree mark 403 on the vertical plate 404. The end of the pointer 402 is fixedly connected to the upper bearing seat 302. The outer wall of the pointer 402 passes through the inner wall of the through hole 401, and the pointer 402 can move inside the through hole 401.

[0035] Working principle:

[0036] When this straight seam welded pipe pushing square device is needed, first, one end of the waste pipe (i.e. the pipe fitting 5 in this case) generated in the straight seam welded pipe production process is placed inside the round roller 307, and the motor 7 is started, so that the motor 7 drives the transmission shaft 6 to rotate through the transmission structure inside the transmission box 2, and then the transmission shafts of the upper and lower layers drive the round roller 307 and the square roller 301 to rotate synchronously and in opposite directions, pushing the originally round pipe fitting 5 gradually to the right, and under the extrusion of the square roller 301, the round pipe fitting 5 is pushed into a square pipe fitting 5, and the waste round pipe is pushed into a square pipe, and then equidistantly cut and used as a finished product pad. This effectively avoids the problem that waste pipes are generated in the existing straight seam welded round pipe production process due to specification changes, roller changes, shunting, equipment failure, etc., and these waste pipes cannot enter the market due to various defects and cannot be secondary processed for subsequent use, resulting in a waste of resources.

[0037] If the size of the pipe 5 changes, the user can rotate the roller adjusting bolt 305 so that the roller adjusting bolt 305 drives the upper bearing seat 302 to adjust its height through a threaded connection, and then adjusts the distance between the upper and lower round rollers 307 and the square roller 301 to adapt to the size change of the pipe 5. At the same time, the height of the upper transmission shaft and the transmission structure inside the connected transmission box 2 will also be adjusted accordingly. The transmission structure and the transmission shaft can be linked through a Schmidt coupling to ensure that the transmission shaft can still achieve rotation transmission with the transmission structure inside the transmission box 2 after the height change.

[0038] Specifically, when rotating and adjusting the roller adjusting bolts 305, the roller adjusting bolts 305 of the same group on the front and rear sides need to be rotated at the same time. At the same time, when the height of the upper bearing seat 302 changes, the pointer 402 can be driven to adjust the height at the same time. When adjusting the height of the bearing seat 302 at other positions, in order to ensure the consistency of the adjustment height, the user can observe whether the pointers 402 on both sides of the same vertical plate 404 are at the same height, thereby ensuring the accuracy of the height adjustment of multiple round rollers 307 and square rollers 301 during the adjustment process, avoiding the problem of poor accuracy caused by the inability to intuitively confirm the height adjustment dimensions of multiple positions in the existing technology.

[0039] Although the invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
