Description

Technical Field

[0001] This invention relates to the field of steel-reinforced composite pipe processing technology, and particularly to a steel wire welding device for steel-reinforced composite pipes. Background Technology

[0002] Steel-reinforced composite pipes are pipes made by combining high-strength steel wire mesh or steel wire spiral reinforcement with thermoplastic matrix such as polyethylene through a composite process. They combine the mechanical strength of metal with the corrosion resistance of plastic and are widely used in fire protection, water supply and drainage, oil and gas transportation and other fields.

[0003] In the production process of steel-reinforced composite pipe, a welding machine is used to weld the weft wires and warp wires into a mesh structure. Then, the steel wire mesh skeleton is combined with polyethylene plastic in a mold and interpenetrated, finally forming a steel-reinforced plastic composite pipe.

[0004] The specific production process is as follows: 1. Steel mesh skeleton forming: Steel wires are resistance welded to form a mesh skeleton. 2. Plastic extrusion: The plastic matrix is ​​melted in the extruder. 3. Composite and cooling: The plastic and steel mesh are composited in the die head and then cooled and sized. 4. Cutting and sealing: After cutting to a fixed length, the pipe ends are injection molded to seal the joint.

[0005] Currently, Chinese patent CN110421243A, published on November 8, 2019, discloses a wire mesh skeleton welding device, including a welding mechanism mounted on a rotating disk via a radial adjustment mechanism and having a welding wheel. Driven by the radial adjustment mechanism, the welding mechanism moves radially towards or away from the wire mesh skeleton, thereby increasing or decreasing the pressure of the welding wheel on the weft threads at the weld point. A notch is opened on the rotating disk, extending radially towards the wire mesh skeleton, and the welding mechanism is installed at the notch on the rotating disk. The welding mechanism is divided into welding... The welding area is the welding wheel, and the conductive area is other components electrically connected to the welding wheel. The welding area and the conductive area are located on opposite sides of the notch along the axial direction of the rotating disk. A protective plate is installed at the notch on the welding area side. A weft pitch adjustment mechanism is installed on the rotating disk near the welding mechanism. The weft pitch adjustment mechanism includes an adjusting screw threaded to the rotating disk. The axis of the adjusting screw is parallel to the normal of the rotating disk. An adjusting wheel is coaxially mounted at the end of the adjusting screw near the welding wheel. An annular groove that is concave inward along the radial direction of the adjusting wheel is formed on the circumferential surface of the adjusting wheel.

[0006] The process involves unwinding the steel wire from the wire roll and then winding it around the welding position for welding. However, during the actual welding process, the surface of the steel wire is prone to having some oxide layer and oil stains. When the oxide layer and oil stains are located at the welding position, the weld is prone to being weak, which is not conducive to ensuring the structural stability of the entire steel wire mesh skeleton. Summary of the Invention

[0007] The purpose of this invention is to provide a steel wire welding device for steel-reinforced composite pipes, which can clean the surface of the steel wire after it is unwound.

[0008] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a steel wire welding device for steel-reinforced composite pipe, comprising an electrode welding station for multiple radial steel wires to pass through, a rotating disk sleeved on the electrode welding station, multiple fixed sleeves disposed on the outer wall of the rotating disk, a steel wire roll sleeved on the fixed sleeves for winding and storing weft steel wires, multiple welding wheels disposed on the inner wall of the rotating disk for passing weft steel wires and for welding weft steel wires onto radial steel wires, and multiple guide wheels disposed on the inner wall of the rotating disk for passing weft steel wires. A cleaning component is provided on the outer wall of the rotating disk for each steel wire roll. The cleaning component includes a first wheel seat fixed on the rotating disk, a first wheel shaft rotatably connected to the first wheel seat, a first grinding wheel fixed on the first wheel shaft for passing steel wires, a second wheel seat fixed on the rotating disk and located on the side of the first wheel seat away from the steel wire roll, a second wheel shaft rotatably connected to the second wheel seat, and a second grinding wheel fixed on the second wheel shaft for passing steel wires. The steel wires are arranged in an S-shape between the first grinding wheel and the second grinding wheel.

[0009] By adopting the above technical solution, when the steel wire in the wire coil is unwound as the rotating disk rotates, the steel wire needs to pass through the first grinding wheel on the first wheel seat and the second grinding wheel on the second wheel seat. The steel wire passes through the first grinding wheel and the second grinding wheel in an S-shape. At this time, the oxide layer on the surface of the steel wire can be polished by the friction between the first grinding wheel and the second grinding wheel and the steel wire. Finally, the oxide layer on the surface of the steel wire can be cleaned, which is beneficial to the stable welding of the steel wire in the future.

[0010] A further configuration of the present invention is as follows: a drive motor for driving the first wheel shaft to rotate is fixed on the first wheel seat; a first pulley is also provided at the end of the first wheel shaft; a pulley shaft is rotatably connected to the second wheel seat and located below the second wheel shaft; a second pulley is provided on the pulley shaft; a transmission belt is provided between the first pulley and the second pulley; a driving gear is provided on the pulley shaft; and a driven gear meshing with the driving gear is provided on the second wheel shaft; under the drive of the drive motor, the rotation direction of the first grinding wheel and the second grinding wheel is opposite to the transmission direction of the steel wire.

[0011] By adopting the above technical solution, the first wheel shaft and the first grinding wheel are driven by a drive motor. At the same time, the first wheel shaft drives the pulley shaft to rotate via a transmission belt. Subsequently, the pulley shaft drives the second wheel shaft and the second grinding wheel to rotate via a drive gear and a driven gear. This achieves that the rotation direction of the first and second grinding wheels is opposite to the transmission direction of the steel wire. This increases the friction between the first and second grinding wheels and the steel wire, which ultimately facilitates the efficient cleaning of the oxide layer on the surface of the steel wire by the first and second grinding wheels.

[0012] A further embodiment of the present invention is that the cleaning assembly further includes a connecting wheel rotatably connected to the outer wall of the rotating disk and located near the first wheel seat, two sponge rings disposed on both sides of the outer wall of the connecting wheel and used to adhere to the left and right sides of the steel wire, a connecting arm disposed on the outer wall of the rotating disk and located between the first wheel seat and the connecting wheel, a first pressure plate disposed on the upper end of the connecting arm, a column disposed on the lower side of the connecting arm, a second pressure plate disposed on the upper end of the column, and sponge plates disposed on the first pressure plate and the second pressure plate and used to adhere to the upper and lower sides of the steel wire.

[0013] By adopting the above technical solution, when the steel wire is unwound from the wire coil, it needs to pass between two sponge rings and two sponge plates. At this time, the two sponge rings can be used to clean the oil stains on the left and right sides of the steel wire, while the two sponge plates can be used to clean the oil stains on the top and bottom sides of the steel wire. Finally, the oil stains on the surface of the steel wire can be cleaned, which is beneficial to the stable welding of the steel wire in the future.

[0014] A further provision of the present invention is that: a third pulley is also provided on the first wheel axle, a connecting shaft is provided at the center of the connecting wheel, a fourth pulley is provided at the end of the connecting shaft, and a linkage belt is provided between the fourth pulley and the third pulley.

[0015] By adopting the above technical solution, when the first wheel shaft rotates, it drives the connecting shaft and connecting wheel to rotate through the linkage belt, thereby driving the sponge ring to rotate. At this time, the rotation direction of the sponge ring is opposite to the transmission direction of the steel wire, which is conducive to the sponge ring to efficiently clean the oil stains on the surface of the steel wire.

[0016] A further feature of the present invention is that a drive cylinder is provided on the rotating disk and located between the connecting arm and the connecting wheel. The piston rod end of the drive cylinder is provided with a fixing plate connected to the lower end of the column. The fixing plate is provided with a mounting seat in the shape of a "U" for the connecting wheel to be embedded in. Both ends of the mounting seat are provided with bearing seats for the connecting shaft to be rotatably connected. The connecting wheel is provided with a cutting assembly for cutting the steel wire after the connecting wheel moves upward.

[0017] By adopting the above technical solution, in the existing technology, when a roll of steel wire is used up, the machine needs to be stopped and the wire head of the new steel wire roll and the wire tail of the old steel wire roll are welded together by welding. However, the connection between the wire tail and the steel wire roll is usually crimped and fixed, so the surface of the wire tail is damaged and the deformed part of the wire needs to be cut off before welding can be performed.

[0018] When the wire roll is about to run out, stop the rotating disc, and then use the drive cylinder to move the column upward so that the first and second pressure plates use soft sponge plates to press and limit the wire. Then, the cutting component on the connecting wheel can be used to cut the wire. Then, the end of the cut wire is welded to the beginning of the new wire roll, which facilitates the quick completion of the cutting and joining operation.

[0019] Meanwhile, due to the compression and limiting effect of the sponge board on the steel wire, the steel wire on the welding wheel and guide wheel can maintain a certain tension after cutting, thus preventing the steel wire from detaching from the welding wheel and guide wheel after it loosens.

[0020] A further configuration of the present invention is as follows: the cutting assembly includes an annular groove formed at the center of the outer wall of the connecting wheel for embedding a steel wire, an opening groove formed at the side of the connecting wheel, two swing arms with one end hinged in the opening groove, a cutter set at the end of the swing arm, a return spring connected at both ends to the two swing arms respectively, a guide ramp set on the outer side wall of the swing arm, a mounting post set on the upper side of the bearing seat, and a drive wheel set on the upper end of the mounting post for abutting against the guide ramp.

[0021] By adopting the above technical solution, when the drive cylinder moves the column and connecting wheel upward, the steel wire can sink and enter the annular groove. As the connecting wheel continues to rotate, when the swing arm in the opening groove rotates to the position of the drive wheel, the drive wheel can abut against the guide ramp. Then the two swing arms can swing towards each other. At this time, the steel wire threaded in the annular groove can be cut by two cutters, and the return spring is compressed. Until the drive wheel passes the guide ramp, the return spring can elastically recover, so that the swing arm returns to its original position.

[0022] A further feature of the present invention is that: a through hole is provided on the rotating disk for the steel wire to pass through and connect to the guide wheel; a perforated guide wheel is provided on the rotating disk at the position of the through hole; and a wheel is rotatably connected on the rotating disk at the position of the second grinding wheel for the steel wire to pass through and extend to the perforated guide wheel.

[0023] By adopting the above technical solution, after the steel wire is cleaned of oil and oxide layer, the steel wire can extend towards the perforated guide wheel under the guidance of the wheel, and then enter the through hole after being guided by the perforated guide wheel. Subsequently, the steel wire can pass through the rotating disk and extend to the position of the guide wheel and welding wheel.

[0024] A further provision of the present invention is as follows: a fixed seat is provided on the rotating disk at the position of the perforated guide wheel; a swing rod is provided on the fixed seat, one end of which is located inside the fixed seat and the other end is rotatably connected to the perforated guide wheel; a swing shaft is provided at one end of the swing rod located inside the fixed seat; a shaft hole is provided on the side wall of the fixed seat for the swing shaft to pass through; a connecting plate is provided at the end of the swing shaft; a return torsion spring is sleeved at the end of the swing shaft, one end of which is connected to the connecting plate and the other end of which is connected to the outer wall of the fixed seat; a positioning plate is provided on the side of the fixed seat near the through hole for abutting against the swing rod; the elastic restoring force of the return torsion spring causes the swing rod to swing toward the positioning plate.

[0025] By adopting the above technical solution, when the rotating disk is working normally and the steel wire is fed into the through hole, the swing rod abuts against the positioning plate, and the positioning plate positions the swing rod and the through guide wheel. When the rotating disk stops working and the steel wire is cut, the steel wire is pulled in the opposite direction away from the through hole. The steel wire can drive the swing rod to swing away from the positioning plate, thereby lowering the height of the through guide wheel. At this time, a portion of the steel wire between the first pressure plate and the second pressure plate can be pulled out for welding, which is conducive to the convenient welding operation.

[0026] A further provision of the present invention is that a connecting post is provided on the rotating disk and on one side of the connecting wheel, and a guide ring for the steel wire to pass through is provided at the upper end of the connecting post.

[0027] By adopting the above technical solution, when the steel wire is unwound from the wire roll, the steel wire needs to pass through the guide ring first. At this time, the guide ring can play a positioning role in the threading angle of the steel wire, so as to avoid the steel wire gradually decreasing in the wire roll affecting the subsequent threading angle of the steel wire.

[0028] The beneficial effects of the present invention are as follows: when the steel wire in the wire coil is unwound as the rotating disk rotates, the steel wire first passes through the guide ring, then passes through the sponge ring, sponge plate, first grinding wheel, second grinding wheel, wheel disk, and perforated guide wheel in sequence before entering the through hole, and then passes through the guide wheel and welding wheel before being used for welding.

[0029] The system utilizes a drive motor to rotate the first wheel shaft and the first grinding wheel. Simultaneously, the first wheel shaft, via a transmission belt, drives a pulley shaft. This pulley shaft, through a drive gear and a driven gear, drives the second wheel shaft and the second grinding wheel. This ensures that the rotation directions of the first and second grinding wheels are opposite to the transmission direction of the steel wire, increasing the friction between the grinding wheels and the steel wire. This facilitates efficient cleaning of the oxide layer on the steel wire surface by the first and second grinding wheels. Simultaneously, the rotation of the first wheel shaft, via a linkage belt, drives the connecting shaft and connecting wheel, which in turn rotates the sponge rings. The rotation direction of the sponge rings is opposite to the transmission direction of the steel wire. As the steel wire passes between the two sponge rings and two sponge plates, the two sponge rings clean the oil stains on the left and right sides of the steel wire, while the two sponge plates clean the oil stains on the top and bottom sides. This comprehensive cleaning of the steel wire surface promotes stable welding of the subsequent steel wire.

[0030] In existing technology, when a roll of steel wire is used up, the machine needs to be stopped and the beginning of a new roll of steel wire and the end of the old roll of steel wire welded together. However, the connection between the end of the steel wire and the roll of steel wire is usually crimped, which damages the surface of the end of the steel wire. This deformed part of the steel wire needs to be cut off before welding. When the roll of steel wire is about to be used up, the rotating disc is stopped, and then the drive cylinder moves the column upward, so that the first and second pressure plates use soft sponge plates to press and limit the steel wire. When the drive cylinder moves the column and connecting wheel upward, the steel wire can sink and enter the annular groove. As the connecting wheel rotates, when the swing arm in the opening groove rotates to the position of the drive wheel, the drive wheel can abut against the guide ramp. Then the two swing arms can swing towards each other. At this time, the steel wire threaded in the annular groove can be cut by two cutters, and the return spring is compressed. This facilitates the quick completion of the cutting and joining operation.

[0031] Meanwhile, due to the compression and limiting effect of the sponge board on the steel wire, the steel wire on the welding wheel and guide wheel can maintain a certain tension after cutting, thereby preventing the steel wire from detaching from the welding wheel and guide wheel after it loosens after cutting.

[0032] When the rotating disk is working normally and the steel wire is fed into the through hole, the swing rod abuts against the positioning plate, and the positioning plate positions the swing rod and the through guide wheel. When the rotating disk stops working and the steel wire is cut, the steel wire is pulled in the opposite direction away from the through hole. The steel wire can drive the swing rod to swing away from the positioning plate, thereby lowering the height of the through guide wheel. At this time, a portion of the steel wire between the first pressure plate and the second pressure plate can be pulled out for welding, which is beneficial to the convenience of welding operation.

When the driving cylinder 5 drives the connecting wheel 47 to move up and down, the upper limit position and the lower limit position of the connecting shaft 471 are symmetrically located on the upper and lower sides of the horizontal center axis of the first wheel shaft 42, so as to ensure the tensioned transmission state of the linkage belt 473.

[0048] Refer to Figure 4 , Figure 7The connecting wheel 47 is also equipped with a cutting assembly 6 for cutting the steel wire after the connecting wheel 47 moves upward.

A positioning plate 84 for abutting against the swing rod 81 is also welded to the side of the fixed seat 8 near the through hole 24. The elastic restoring force of the reset torsion spring 822 causes the swing rod 81 to swing toward the positioning plate 84. When the swing rod 81 abuts against the positioning plate 84, the swing rod 81 is in a state of tilting toward the side closer to the positioning plate 84.

[0050] Working principle: When the steel wire in the wire coil 3 is unwound as the rotating disk 2 rotates, the steel wire first passes through the guide ring 91, and then passes through the sponge ring 48, sponge plate 404, first grinding wheel 43, second grinding wheel 46, wheel disk 25, and perforated guide wheel 7 in sequence before entering the through hole 24. After passing through the guide wheel 23 and welding wheel 22, it is used for welding.

[0051] The system utilizes a drive motor 411 to rotate the first wheel shaft 42 and the first grinding wheel 43. Simultaneously, the first wheel shaft 42 drives a pulley shaft 441 via a transmission belt 443. The pulley shaft 441 then drives a second wheel shaft 45 and a second grinding wheel 46 via a drive gear 444 and a driven gear 451. This ensures that the rotation direction of the first and second grinding wheels 43 and 46 is opposite to the transmission direction of the steel wire. This increases the friction between the first and second grinding wheels 43 and 46 and the steel wire, ultimately facilitating the grinding of the oxide layer on the steel wire surface by the first and second grinding wheels 43 and 46. Highly efficient cleaning; simultaneously, when the first wheel shaft 42 rotates, it drives the connecting shaft 471 and the connecting wheel 47 to rotate via the linkage belt 473, thereby driving the sponge ring 48 to rotate. At this time, the rotation direction of the sponge ring 48 is opposite to the transmission direction of the steel wire. The steel wire passes between the two sponge rings 48 and the two sponge plates 404. At this time, the two sponge rings 48 can be used to clean the oil stains on the left and right sides of the steel wire, while the two sponge plates 404 can be used to clean the oil stains on the upper and lower sides of the steel wire. Finally, the oil stains on the surface of the steel wire can be cleaned, which is beneficial to the stable welding of the steel wire in the future.

[0052] In existing technology, when a roll of steel wire 3 is used up, the machine needs to be stopped and the beginning of the new roll of steel wire 3 and the end of the old roll of steel wire 3 need to be welded together. However, the connection between the end of the steel wire and the roll of steel wire 3 is usually crimped, which damages the surface of the end of the steel wire. This deformed part of the steel wire needs to be cut off before welding can be performed. At this time, when the roll of steel wire 3 is about to be used up, the rotating disk 2 is stopped, and then the drive cylinder 5 drives the column 402 to move upward, so that the first pressure plate 401 and the second pressure plate 403 are supported by soft sponge board. 404 clamps and limits the steel wire; when the drive cylinder 5 moves the column 402 and connecting wheel 47 upward, the steel wire can sink and enter the annular groove 61. As the connecting wheel 47 rotates, when the swing arm 63 in the opening groove 62 rotates to the position of the drive wheel 68, the drive wheel 68 can abut against the guide ramp 66. Then the two swing arms 63 can swing towards each other. At this time, the steel wire passing through the annular groove 61 can be cut by the two cutters 64, and the return spring 65 is compressed; thus, it is beneficial to quickly complete the cutting and joining operation.

[0053] Meanwhile, due to the compression and limiting effect of the sponge board 404 on the steel wire, the steel wire on the welding wheel 22 and the guide wheel 23 can maintain a certain tension after cutting, thereby preventing the steel wire from detaching from the welding wheel 22 and the guide wheel 23 after the cutting is relaxed.

[0054] When the rotating disk 2 is working normally and the steel wire is fed into the through hole 24, the swing rod 81 abuts against the positioning plate 84, and the positioning plate 84 positions the swing rod 81 and the perforated guide wheel 7. When the rotating disk 2 stops working and the steel wire is cut, the steel wire is pulled in the opposite direction away from the through hole 24. The steel wire can drive the swing rod 81 to swing away from the positioning plate 84, thereby lowering the height of the perforated guide wheel 7. At this time, a portion of the steel wire between the first pressure plate 401 and the second pressure plate 403 can be pulled out for welding, which is beneficial to the convenience of welding operation.
