Description

Technical Field

[0001] The utility model relates to the technical field of straight seam welded pipe edge grinding, in particular to a straight seam welded pipe unit which is convenient for adjusting an edge grinding wheel. Background Technique

[0002] A straight seam welded pipe is a kind of steel pipe, whose weld seam is parallel to the longitudinal direction of the steel pipe. It is usually made by rolling and welding hot-rolled or cold-rolled steel plates or steel strips. The welding process is carried out on welding equipment, and the weld seam is linear. During the processing of the weld seam of the straight seam welded pipe, an edge grinding wheel is needed to polish the burrs and welding chips near the weld seam. Currently, the common way of grinding with an edge grinding wheel is to install the edge grinding wheel on the outer side of the weld seam of the straight seam welded pipe. As the straight seam welded pipe is continuously conveyed, the edge grinding wheel rotates and grinds at the weld seam position to achieve the effect of grinding the weld seam of the straight seam welded pipe.

[0003] Due to the wear and damage on the outer side of the edge grinding wheel after long-term use, it is necessary to regularly check and replace the edge grinding wheel. When replacing or overhauling the edge grinding wheel, the edge grinding work of the straight seam welded pipe will stop, affecting the edge grinding efficiency of the straight seam welded pipe. Moreover, in order to ensure the edge grinding effect and avoid adverse effects on the material of the welded pipe during edge grinding, it is very necessary to select an edge grinding wheel that matches the material of the straight seam welded pipe. For example, for a straight seam welded pipe with high hardness and high wear resistance, an edge grinding wheel with high wear resistance needs to be selected. However, the commonly used edge grinding units cannot replace the edge grinding wheels of different materials according to the material of the straight seam welded pipe for edge grinding, affecting the edge grinding effect of the weld seam of the straight seam welded pipe. Content of the Utility Model

[0004] The purpose of the utility model is to provide a straight seam welded pipe unit which is convenient for adjusting an edge grinding wheel to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A straight seam welded pipe unit which is convenient for adjusting an edge grinding wheel includes a bottom plate. A plurality of guiding brackets are fixed on the top surface of the bottom plate. A machine table is fixed on the top surface of the bottom plate. Support panels are fixed at both ends of the top surface of the machine table. A guide rail is fixed on the top surface of the support panel. A lead screw is rotatably connected inside the guide rail. An L-shaped support plate which is slidably connected with the guide rail is screwed on the outer side of the lead screw. A telescopic assembly is fixed on the top surface of the L-shaped support plate. An edge grinding mechanism is sleeved and fixed at the top end of the telescopic assembly. The edge grinding mechanism includes a U-shaped frame. A connecting shaft is rotatably connected inside the U-shaped frame. An edge grinding wheel is sleeved and fixed on the outer side of the connecting shaft. Two driving mechanisms are fixed on the top surface of the machine table. Each driving mechanism includes a cylinder. A machine box for driving the edge grinding wheel at the corresponding position to rotate is fixed at the output end of the cylinder.

[0007] Furthermore, the guide bracket comprises two support rods, two rubber rollers are detachably and rotatably connected between the tops of the two support rods, and a straight seam welded pipe body is drivingly connected between the two rubber rollers.

[0008] Furthermore, a motor 1 is fixed to one end of the guide rail, and an output end of the motor 1 is fixedly connected to one end of a lead screw.

[0009] Furthermore, a second motor is fixed inside the chassis, a driving gear is fixed to the output end of the second motor, a driven gear is sleeved and fixed to the outer side of the connecting shaft, and the driving gear is meshed with the driven gear for transmission.

[0010] Furthermore, the cylinder is plugged and fixed to the machine platform, a transmission block is fixed to one side of the L-shaped support plate, and the transmission block is screwed and connected to the screw rod.

[0011] Furthermore, the telescopic assembly includes a support column fixedly connected to the L-shaped support plate, a sleeve 1 is slidably sleeved on the outer side of the support column, and a sleeve 2 is slidably sleeved on the outer side of the sleeve 1.

[0012] Furthermore, a slide block 1 is fixed on both sides of the top of the support column, and two slide grooves 1 are provided on the inner side of the sleeve 1 and are slidably connected to the slide blocks 1 at corresponding positions.

[0013] Furthermore, two slide blocks 2 are fixed on both sides of the top of the sleeve 1, and two slide grooves 2 are provided on the inner side of the sleeve 2 and are respectively slidably connected to the slide blocks 2 at corresponding positions.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The output end of the cylinder drives the driving gear on the chassis to mesh with the driven gear on the connecting shaft. The second motor inside the chassis drives the driving gear to rotate, causing the driven gear to drive the grinding wheel on the connecting shaft to rotate, and the weld of the straight seam welded pipe on the guide bracket to contact the outer side of the grinding wheel. As the grinding wheel rotates, it is convenient to grind the weld. By arranging two cylinders, chassis, and driving gears at the bottom of the straight seam welded pipe, one cylinder can first drive the driving gear on the chassis to move up and drive the grinding wheel to rotate and grind. When the grinding wheel is worn or needs to be repaired, , another cylinder can bring another chassis and driving gear to move up and bring another edging wheel to rotate and grind. The previous edging wheel will move down and leave the straight seam welded pipe synchronously because of losing support during the process of the cylinder bringing the chassis down. The edging wheel falls onto the L-shaped support plate for inspection or disassembly and replacement. By alternating the edging wheels on the top of the two cylinders, there is still a spare edging wheel for weld edging during the inspection or replacement of the damaged edging wheel, so that the weld edging of the straight seam welded pipe and the inspection of the edging wheel can be carried out at the same time, which is beneficial to improving the efficiency of edging the straight seam welded pipe.

[0016] 2. Two guide rails are fixed on the top of the machine, and multiple grinding wheels are slidably engaged on each guide rail through a screw rod. Multiple grinding wheels can be used as spare grinding wheels. When one grinding wheel on the guide rail is damaged, the screw rod can be rotated to make the L-shaped support plate adjust the spare grinding wheel to the bottom of the weld of the straight seam welded pipe, which is convenient for quick replacement and use of new grinding wheels, and improves the efficiency of adjustment and replacement of grinding wheels;

[0017] Multiple edge grinding wheels can be made of different materials, which is convenient for grinding straight seam welded pipes of different materials. The edge grinding wheel that matches the material of the straight seam welded pipe can be transferred to the bottom of the weld of the straight seam welded pipe for standby. The edge grinding wheels of different materials can be replaced according to the material of the straight seam welded pipe for edge grinding, which is conducive to improving the edge grinding effect of the weld of the straight seam welded pipe;

[0018] The cylinder moves the chassis upward so that the convex block on the top of the chassis can move up to different positions and heights against the L-shaped support plate and the grinding wheel. When the diameter of the straight seam welded pipe is small, the support height of the cylinder is lowered. When the diameter of the straight seam welded pipe is large, the support height of the cylinder is increased to meet the grinding requirements of straight seam welded pipes of different diameters.

DETAILED DESCRIPTION

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1

[0027] Please refer to Figure 1-4 , in the embodiment of the present invention, a straight seam welded pipe unit facilitating the adjustment of an edge grinding wheel includes a bottom plate 100. A plurality of guiding brackets 110 are fixed on the top surface of the bottom plate 100. A machine table 200 is fixed on the top surface of the bottom plate 100. Support panels 210 are fixed at both ends of the top surface of the machine table 200. A guide rail 300 is fixed on the top surface of the support panel 210. A lead screw 310 is rotatably connected inside the guide rail 300. An L-shaped support plate 400 slidably connected to the guide rail 300 is screwed on the outer side of the lead screw 310. A telescopic assembly 500 is fixed on the top surface of the L-shaped support plate 400. An edge grinding mechanism 600 is sleeved and fixed at the top end of the telescopic assembly 500. The edge grinding mechanism 600 includes a U-shaped frame 610. A connecting shaft is rotatably connected inside the U-shaped frame 610. An edge grinding wheel 620 is sleeved and fixed on the outer side of the connecting shaft. Two driving mechanisms 700 are fixed on the top surface of the machine table 200. The driving mechanism 700 includes a cylinder 710. A machine box 720 for driving the edge grinding wheel 620 at the corresponding position to rotate is fixed at the output end of the cylinder 710.

[0028] Specifically, two cylinders 710 and machine boxes 720 are arranged at the bottom of the straight seam welded pipe. First, one cylinder 710 drives the machine box 720 to move upward to drive the edge grinding wheel 620 to rotate for edge grinding. When the edge grinding wheel 620 is worn or needs to be repaired, the other cylinder 710 drives the other machine box 720 to move upward to drive the other edge grinding wheel 620 to rotate for edge grinding. The edge grinding wheels 620 at the tops of the two cylinders 710 are alternately used to realize that during the process of repairing or replacing the damaged edge grinding wheel 620, there is still a spare edge grinding wheel 620 for edge grinding the weld seam, so that the edge grinding of the weld seam of the straight seam welded pipe and the repair of the edge grinding wheel 620 are carried out simultaneously, which is beneficial to improving the edge grinding efficiency of the straight seam welded pipe.

[0029] As Figure 1 shown, in this embodiment, the guiding bracket 110 includes two support rods. Two rubber rollers are detachably and rotatably connected between the tops of the two support rods. A straight seam welded pipe body 800 is drivingly connected between the two rubber rollers. This part is the prior art, and the working principle can be briefly described as using the rubber rollers on the guiding bracket 110 to convey the straight seam welded pipe to the position of the edge grinding wheel 620 for edge grinding, and the distance between the two rubber rollers on the same guiding bracket 110 can be adjusted according to the diameter of the straight seam welded pipe.

[0030] As Figure 4 shown, in this embodiment, a first motor 320 is fixed at one end of the guide rail 300, and the output end of the first motor 320 is fixedly connected to one end of the lead screw 310. A second motor is fixed inside the chassis 720, and the output end of the second motor is fixed with a driving gear 730. A driven gear 630 is fixedly sleeved on the outside of the connecting shaft, and the driving gear 730 is in meshing transmission with the driven gear 630.

[0031] In this embodiment, the first motor 320 drives the lead screw 310 to rotate to drive the edge grinding wheels 620 at different positions to adjust their positions. The chassis 720 moves upward so that the convex block on its top surface contacts the C-shaped frame 610. At this time, the driving gear 730 and the driven gear 630 are in a meshing state. The second motor drives the driving gear 730 to rotate, so that the driven gear 630 drives the edge grinding wheels 620 to rotate to grind the weld seam.

[0032] As Figure 1 and Figure 4 shown, in this embodiment, the air cylinder 710 is inserted and fixed to the machine table 200. A transmission block is fixed on one side of the L-shaped support plate 400, and the transmission block is in threaded connection with the lead screw 310. Thus, when the lead screw 310 rotates, the transmission block in threaded connection with it drives the L-shaped support plate 400 to move.

[0033] During specific implementation, the guiding bracket 110 conveys the straight seam welded pipe towards the direction of the grinding wheel 620. Among them, the output end of one air cylinder 710 drives the chassis 720 to move upward, so that the driving gear 730 outside the chassis 720 is in meshing transmission with the driven gear 630. The telescopic assembly 500 extends, so that the C-shaped frame 610 drives the edge grinding wheels 620 to move upward to the position of the weld seam of the straight seam welded pipe. Then, the second motor inside the chassis 720 drives the driving gear 730 to rotate, so that the driven gear 630 drives the edge grinding wheels 620 on the connecting shaft to rotate, and the edge grinding wheels 620 grind the weld seam of the straight seam welded pipe. When it is necessary to replace or repair the edge grinding wheels 620, the output end of the other air cylinder 710 also drives the chassis 720 to move upward. Similarly, the C-shaped frame 610 at the top of the other chassis 720 drives the edge grinding wheels 620 to move upward, so that the other edge grinding wheels 620 grind at the weld seam position. Then, the output end of the air cylinder 710 that started to extend is shortened. At this time, the chassis 720 at the output end of this air cylinder 710 moves downward to below the L-shaped support plate 400. The C-shaped frame 610 without the support of the chassis 720 moves downward under its own gravity, and the length of the telescopic assembly 500 becomes shorter. The C-shaped frame 610 drives the edge grinding wheels 620 back to the L-shaped support plate 400. At this time, the first motor 320 can be driven to drive the lead screw 310 to rotate, so that the edge grinding wheels 620 that just fell onto the L-shaped support plate 400 move along with the lead screw 310 in a threaded manner, so that the spare brand-new edge grinding wheels 620 can move to the lower part of the weld seam for standby.

[0034] Embodiment 2

[0035] On the basis of the first embodiment, in order to stably move the C-shaped frame 610 up and down.

[0036] As Figure 4 and Figure 5 shown, in this embodiment, the telescopic assembly 500 includes a support column 510 fixedly connected to the L-shaped support plate 400. A sleeve one 520 is slidably sleeved on the outer side of the support column 510. A sleeve two 530 is slidably sleeved on the outer side of the sleeve one 520. On both sides of the top of the support column 510, a slider one 511 is fixed. On the inner side of the sleeve one 520, two sliding grooves one 522 are respectively formed and slidably connected to the slider one 511 at the corresponding position. On both sides of the top of the sleeve one 520, a slider two 521 is fixed. On the inner side of the sleeve two 530, two sliding grooves two 531 are respectively formed and slidably connected to the slider two 521 at the corresponding position.

[0037] In this embodiment, during the upward movement of the C-shaped frame 610, the sleeve two 530 slides upward from the outer side of the sleeve one 520, and the sleeve one 520 slides upward from the outer side of the support column 510, so as to satisfy the stable upward movement of the C-shaped frame 610 to different position heights to be承接 under the weld of the straight seam welded pipe. During the process of the sleeve one 520 sliding along the support column 510, the sleeve one 520 will not脱离 the support column 510. During the process of the sleeve two 530 sliding along the sleeve one 520, the sleeve two 530 will not脱离 the sleeve one 520.
