Description

Technical Field

[0001] This invention relates to the field of shearing and butt welding technology, specifically to a shearing and butt welding device and processing method for the production of pre-embedded channels. Background Technology

[0002] Structural embedded channels are steel products widely used in tunnels, subways, bridges, culverts, underground utility tunnels, and other similar projects. These channels are pre-installed (embedded) within concealed works, serving as components placed during structural casting and used for overlapping during the construction of the superstructure to facilitate the installation and fixing of external engineering equipment foundations. Among these, the Hafen structural embedded channel is the most well-known, characterized by its high corrosion resistance, ease of installation and maintenance, high quality, and high reliability. It has been successfully applied in various tunnel and other engineering projects.

[0003] In the early stages of production of pre-embedded channels for structures, steel coils need to be butt-welded. This involves using a shearing butt-welding machine to cut two steel coils separately and then welding them together. However, since the steel coils have a certain weight, manual support is required during welding, which not only increases the labor burden but also introduces a risk factor. Moreover, the lack of a pressing mechanism during the welding process makes the bond between the two steel coils not strong enough. Summary of the Invention

[0004] The purpose of this invention is to provide a shearing and welding device for the production of pre-embedded channels, so as to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A shearing and welding device for the production of pre-embedded channels includes a shearing and welding machine for welding a pair of steel coils. The shearing and welding machine includes a control unit, a shearing unit installed on the top of the control unit, and a welding unit installed on the top of the shearing unit. The welding unit includes a welding box, a feeding chute is provided at the outer end of the welding box, and a hydraulic cylinder is provided inside the welding box. A welding gun is provided at the end of the hydraulic cylinder.

[0007] The welding box is equipped with a clamping component, which includes a limiting frame. An eccentric wheel is rotatably arranged on the inner side of the limiting frame. The eccentric wheel is arranged at an inward inclination. An elastic element is provided between the eccentric wheel and the limiting frame. A stop bar is provided on the inner bottom surface of the limiting frame to limit the limiting frame. The end of the steel coil is restricted between the eccentric wheel and the limiting frame, making it difficult to slip off.

[0008] Furthermore, the limiting frame is provided with a pressing component, which includes a support plate fixedly connected to the inner wall of the welding box. Multiple reset components are fixedly connected to the side end of the support plate. An arc-shaped block is fixedly connected to the end of the reset component and is provided with an arc-shaped block on the limiting frame. A driving component is provided at the outer end of the arc-shaped block. The driving component is used to press the arc-shaped block, so that the limiting frame moves the end of the steel coil a set distance.

[0009] Furthermore, adjacent pairs of the arc-shaped blocks are slidably arranged, the top of the limiting frame is provided with multiple sliding grooves, and the bottom of the arc-shaped block is provided with a slider, which slides inside the sliding groove.

[0010] Furthermore, the driving component includes a movable sleeve fixedly fitted to the outside of the welding torch. A driving rod is provided at the outer end of the movable sleeve. A movable shaft is fixedly connected to the bottom of the driving rod. A push roller is rotatably connected to the outer end of the movable shaft. During the movement of the welding torch, the push roller moves with the welding torch, and the arc-shaped blocks are squeezed in sequence, so that the ends of a pair of steel coils are brought closer together, thereby improving the weld strength.

[0011] Furthermore, the driving component also includes a driving frame, the side end of which is fixedly connected to the end of the hydraulic cylinder, a rotating sleeve is rotatably connected to the inner side of the driving frame, and the outer end of the rotating sleeve is fixedly connected to a movable sleeve.

[0012] Optionally, the side end of the arc-shaped block is provided with a locking component, the locking component including a first sleeve fixedly connected to the side end of the arc-shaped block, and a plurality of second sleeves corresponding to the first sleeve fixedly connected to the side end of the support plate. During the movement of the arc-shaped block, its corresponding first sleeve engages with the second sleeve.

[0013] Furthermore, the outer ring of the second sleeve is fixedly fitted with an annular retaining ring, the first sleeve has a slot, the inner wall of the slot is provided with a telescopic member, the top of the telescopic member is movably provided with a pull rod, the bottom of the telescopic member is provided with a limit block, and the annular retaining ring moves to the side of the limit block to complete the engagement.

[0014] A processing method for producing embedded channels, employing the aforementioned shearing and welding device for producing embedded channels.

[0015] Uncoiling: Place the two sets of steel coils on the uncoiler and uncoil them respectively;

[0016] Shearing and welding: After shearing the ends of the two sets of steel coils flat, they are welded using a welding gun;

[0017] Loop storage: The above-mentioned steel coils are stored using a loop storage system;

[0018] Initial forming: The strip steel enters the first roll forming machine and is continuously bent to initially form a channel steel cross-section.

[0025] Material cutting, packaging and warehousing: After being cut to length, the finished product is output to the output roller conveyor. The pre-embedded grooved finished product enters the packaging machine through the horizontal platform for packaging and warehousing.

[0026] In the above technical solution, the shearing and welding device for pre-embedded channel production provided by the present invention has the following beneficial effects:

[0027] The device of this invention, by moving the welding torch, causes the push roller to rotate slowly, causing a pair of limiting frames to press the corresponding steel coils against each other little by little. This presses the already molten weld pool, allowing it to press against each other during solidification, thereby improving the weld strength of the steel coils. The method of this invention not only solves the technical problems of non-continuous production and large equipment footprint in the prior art, but also avoids the technical problems of requiring 3-4 heating cycles in the prior art, and finally avoids the technical problems of damaging material properties when repeatedly bending and forming.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0045] Example 1, please refer to Figure 1-5 A shearing and welding device for pre-embedded channel production includes a shearing and welding machine 1 for welding a pair of steel coils. The shearing and welding machine 1 includes a control unit 11, a shearing unit 12 mounted on the top of the control unit 11, and a welding unit 13 mounted on the top of the shearing unit 12. The welding unit 13 includes a welding box 131, with a feed chute 132 at the outer end of the welding box 131. A hydraulic cylinder 133 is installed inside the welding box 131, and a welding gun 134 is installed at the end of the hydraulic cylinder 133. A clamping component 2 is installed inside the welding box 131. The clamping component 2 includes a limiting frame 21. An eccentric wheel 22 is rotatably arranged on the inner side of the limiting frame 21. The eccentric wheel 22 is arranged with an inward inclination. An elastic element 23 is provided between the eccentric wheel 22 and the limiting frame 21. A stop bar 24 is provided on the inner bottom surface of the limiting frame 21 to limit the limiting frame 21. The end of the steel coil is restricted between the eccentric wheel 22 and the limiting frame 21, making it difficult to slip off.

[0046] Specifically, a support rod is fixedly connected inside the limiting frame 21, and an eccentric wheel 22 is movably sleeved on the outside of the support rod. The side end of the eccentric wheel 22 is connected to the inner wall of the limiting frame 21 by an elastic element 23, which can be a torsion spring. The eccentric wheel 22 has an arc-shaped protrusion, and the protrusion is covered with one side of elastic silicone (or elastic plastic). The eccentric wheel 22 is inclined inward. When the end of the steel coil is pushed to move, the eccentric wheel 22 rotates inward. If the steel coil moves backward, the eccentric wheel 22 has a tendency to rotate outward. Since the outer diameter changes when the eccentric wheel 22 rotates, it will strengthen the compression of the steel coil and force the steel coil not to move backward.

[0047] Specifically, the inner bottom of the welding box 131 is provided with a support platform 25, and the surface of the support platform 25 is smooth.

[0048] By setting the stop bar 24, the position of the limit frame 21 is limited, so that the steel coil will not pull the limit frame 21 to move outward, thus eliminating the possibility that the steel coil will move due to the movement of the limit frame 21 itself.

[0049] In a further embodiment of the present invention, a pressing component 3 is provided on the limiting frame 21. The pressing component 3 includes a support plate 31 fixedly connected to the inner wall of the welding box 131. A plurality of reset components 32 (which may be strong springs) are fixedly connected to the side end of the support plate 31. An arc-shaped block 33 is fixedly connected to the end of the reset component 32 and is provided on the limiting frame 21. A driving component 4 is provided at the outer end of the arc-shaped block 33. The driving component 4 is used to press the arc-shaped block 33, so that the limiting frame 21 moves the end of the steel coil a set distance. Adjacent pairs of arc-shaped blocks 33 are slidably arranged. A plurality of sliding grooves are opened on the top of the limiting frame 21. A slider is provided at the bottom of the arc-shaped block 33 and slides inside the sliding groove.

[0050] In a further embodiment of the present invention, the driving component 4 includes a movable sleeve 41 fixedly sleeved outside the welding torch 134. A driving rod 42 is provided at the outer end of the movable sleeve 41. A movable shaft 43 is fixedly connected to the bottom of the driving rod 42. A push roller 44 is rotatably connected to the outer end of the movable shaft 43 (a limit ring is fixedly sleeved on the inner wall of the push roller 44, and an annular groove is opened on the outer wall of the movable shaft 43, with the limit ring rotating in the annular groove). During the movement of the welding torch 134, the push roller 44 moves with it, sequentially squeezing the arc-shaped block 33, so that the ends of a pair of steel coils are brought closer together, thereby improving the welding strength.

[0051] Specifically, the limit frame 21 is provided with a guide groove 47, and a slider is fixedly connected to the bottom of the moving shaft 43, and the slider slides inside the guide groove 47.

[0052] Specifically, the drive rod 42 is rotatably connected to the movable sleeve 41.

[0053] In the embodiments provided by the present invention, the driving component 4 further includes a driving frame 45, the side end of the driving frame 45 is fixedly connected to the end of the hydraulic cylinder 133, a rotating sleeve 46 is rotatably connected to the inner side of the driving frame 45, and the outer end of the rotating sleeve 46 is fixedly connected to the movable sleeve 41.

[0054] Friction damping is provided between the drive frame 45 and the rotating sleeve 46, and the angle of the welding torch 134 can be manually adjusted. In this case, it is set to tilt between 30 and 60 degrees, tilting in the direction of movement.

[0055] Initially, the ends of a pair of steel coils are inserted into the welding box 131 through the feed chute 132. The ends of the steel coils enter between the eccentric wheel 22 and the limiting frame 21. The eccentric wheel 22 swings intermittently, allowing the steel coils to enter easily. After the steel coils are fixed, the hydraulic cylinder 133 is activated. The end of the hydraulic cylinder 133 moves the welding gun 134. The welding gun 134 first welds the front end of the steel coil. After welding a small part, the push roller 44 is moved by the drive rod 42 and the moving shaft 43. During the movement of the push roller 44, multiple arc-shaped blocks 33 are pressed, causing the limiting frame 21 to bring the steel coils closer together little by little until the pair of steel coils are completely close together, improving the strength of the steel coil welding.

[0056] During welding, the area to be welded is in a molten state. Initially, the steel coils are close to each other. Once they are partially molten, they are squeezed together, which makes the two stick together more firmly. After welding a short distance, the push roller 44 approaches the first arc block 33, and only then does it begin to push the steel coil to move.

[0057] Example 2 differs from Example 1 in that the following technical features are added: Please refer to... Figure 6-7 The arc-shaped block 33 has a locking component 5 on its side end. The locking component 5 includes a first retainer 51 fixedly connected to the side end of the arc-shaped block 33. The side end of the support plate 31 is fixedly connected to a plurality of second retainers 52 corresponding to the first retainer 51. During the movement of the arc-shaped block 33, the corresponding first retainer 51 and second retainer 52 are locked together. The outer ring of the second retainer 52 is fixedly fitted with an annular retainer 53. The first retainer 51 has a slot. The inner wall of the slot is provided with a telescopic member 55. The top of the telescopic member 55 is movably provided with a pull rod 54. The bottom of the telescopic member 55 is provided with a limit block 56. The annular retainer 53 moves to the side end of the limit block 56 to complete the locking.

[0058] Specifically, the telescopic component 55 includes a fixed cylinder 551, which is fixedly connected to the inner wall of the slot. A sliding rod 552 is slidably connected to the inner wall of the fixed cylinder 551. A telescopic spring 553 is fixedly connected between the sliding rod 552 and the fixed cylinder 551. The top end of the sliding rod 552 is fixedly connected to the bottom end of the pull rod 54. Pulling the pull rod 54 can move the sliding rod 552. A pull plate is connected to multiple pull rods 54. Pulling the pull plate can move multiple pull rods 54 at the same time.

[0059] When the first arc-shaped block 33 moves, the arc-shaped block 33 moves along with the first retaining sleeve 51, causing the limiting block 56 to gradually approach the annular retaining ring 53. Through the compression of the annular retaining ring 53, the limiting block 56 rises and compresses the telescopic spring 553, ultimately causing the second retaining sleeve 52 to engage inside the first retaining sleeve. Subsequently, simply pulling the pull plate will cause the pull rod 54 to lift multiple sliding rods 552, disengaging the annular retaining ring 53 from the limiting block 56. Under the action of the reset member 32, the limiting member returns to its initial position.

[0060] Example 3 differs from Example 2 in that the following technical features are added: Please refer to... Figure 8 The bottom of the hydraulic cylinder 133 is provided with a roller pressing component 6. The roller pressing component 6 includes a driven rod 61 located at the bottom of the drive frame 45. The end of the driven rod 61 is provided with a rolling roller 62. The rolling roller 62 presses the extruded weld pool to make its surface smooth.

[0061] When a section of the steel coil approaches, the rolling roller 62 begins to roll and rolls over that section, effectively ensuring that the welded area is smooth and free of protrusions.

[0062] Please see Figure 9-11 A processing method for producing pre-embedded channels, employing the aforementioned shearing and welding device for producing pre-embedded channels.
