Description

Technical Field

[0001] The invention relates to the technical field of shearing butt welding, and in particular to a shearing butt welding device and a processing method for producing embedded channels. Background Art

[0002] Structural embedded channels are a type of steel product widely used in tunnels, subways, bridges, culverts, underground pipe corridors, and other sites. These are pre-installed (buried) components within concealed projects. These components are placed during the structure pouring process and used for overlapping during superstructure construction, facilitating the installation and securing of external engineering equipment foundations. Among these, the most renowned structural embedded channels are HALFEN's structural embedded channels, which offer exceptional corrosion resistance, ease of installation and maintenance, and high quality and reliability. These products have found excellent application in various tunnel and other projects.

[0003] In the early stages of production of embedded structural channels, steel coils need to be butt-welded. This involves using a shearing butt-welding machine to shear two steel coils separately and then weld them together. However, due to the weight of the steel coils, manual support is required during welding, which not only increases the labor burden but also poses a risk. Furthermore, the lack of a squeezing mechanism during welding results in a weak bond between the two steel coils. Summary of the Invention

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0019] Example 1, please refer to Figure 1-5, a shearing and welding device for pre-buried groove production includes a shearing and welding machine 1 for welding a pair of steel coils, the shearing and welding machine 1 includes a control part 11, a shearing part 12 installed on the top of the control part 11 and a welding part 13 installed on the top of the shearing part 12, the welding part 13 includes a welding box 131, the outer end of the welding box 131 is provided with a feeding trough 132, the interior of the welding box 131 is provided with a hydraulic cylinder 133, and the end of the hydraulic cylinder 133 is provided with a welding gun 134; the interior of the welding box 131 is provided with a clamping component 2, the clamping component 2 includes a limit frame 21, the inner side of the limit frame 21 is rotatably provided with an eccentric wheel 22, the eccentric wheel 22 is arranged to be inclined inwardly, an elastic member 23 is provided between the eccentric wheel 22 and the limit frame 21, and the inner bottom surface of the limit frame 21 is provided with a baffle 24, which limits the limit frame 21, and the end of the steel coil is restricted between the eccentric wheel 22 and the limit frame 21, and is not easy to slip.

[0020] Specifically, a support rod is fixedly connected to the limiting frame 21, and the eccentric wheel 22 is movably connected to 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 member 23. The elastic member 23 can be a torsion spring. The eccentric wheel 22 has an arc convex point, and the convex point is covered with elastic silicone (or elastic plastic) on one side. The eccentric wheel 22 is tilted 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, the squeezing of the steel coil will be strengthened, forcing the steel coil not to move backward.

[0021] Specifically, a support platform 25 is provided on the inner bottom of the welding box 131 , and the surface of the support platform 25 is smooth.

[0022] By providing the blocking bar 24, the position of the limiting frame 21 is limited so that the steel coil will not pull the limiting frame 21 to move outward, thereby eliminating the situation where the limiting frame 21 itself moves and causes the steel coil to move.

[0023] In an embodiment further provided by the present invention, an extrusion component 3 is provided on the limit frame 21, and the extrusion component 3 includes a support plate 31 fixedly connected to the inner wall of the welding box 131, and a plurality of reset members 32 (which can be strong springs) are fixedly connected to the side ends of the support plate 31, and the ends of the reset members 32 are fixedly connected to an arc block 33 arranged on the limit frame 21, and a driving component 4 is provided at the outer end of the arc block 33. The driving component 4 is used to squeeze the arc block 33 so that the limit frame 21 moves the end of the steel coil a set distance; an adjacent pair of arc blocks 33 are slidingly arranged, and a plurality of slide grooves are opened on the top of the limit frame 21, and a slider is provided at the bottom of the arc block 33, and the slider slides inside the slide groove.

[0024] In an embodiment further provided by the present invention, the driving component 4 includes a movable sleeve 41 fixedly sleeved on the outside of the welding gun 134, a driving rod 42 is provided at the outer end of the movable sleeve 41, the bottom of the driving rod 42 is fixedly connected to a movable shaft 43, and the outer end of the movable shaft 43 is rotatably connected to a push roller 44 (the inner wall of the push roller 44 is fixedly sleeved with a limiting ring, the outer wall of the movable shaft 43 is provided with an annular groove, and the limiting ring rotates in the annular groove). During the movement of the welding gun 134, the push roller 44 is moved with it, squeezing the arc blocks 33 in turn, so that the ends of a pair of steel coils are closer together, thereby improving the firmness of the welding.

[0025] Specifically, a guide groove 47 is defined on the limiting frame 21 , and a slider is fixedly connected to the bottom of the movable shaft 43 , and the slider slides inside the guide groove 47 .

[0026] Specifically, the driving rod 42 and the moving sleeve 41 are rotationally connected.

[0027] In the embodiment provided by the present invention, the driving component 4 also includes a driving frame 45, the side end of the driving frame 45 is fixedly connected to the end of the hydraulic cylinder 133, the inner side of the driving frame 45 is rotatably connected to a rotating sleeve 46, and the outer end of the rotating sleeve 46 is fixedly connected to the movable sleeve 41.

[0028] A friction damper is provided between the driving frame 45 and the rotating sleeve 46, and the angle of the welding gun 134 can be manually adjusted. In this case, it is set to tilt between 30-60 degrees, tilting in the direction of movement.

[0029] Initially, the ends of a pair of steel coils are respectively inserted into the interior of the welding box 131 from the feed trough 132, and the ends of the steel coils enter between the eccentric wheel 22 and the limit frame 21. The eccentric wheel 22 swings intermittently so that the steel coils can enter easily. Then, after the steel coils are fixed, the hydraulic cylinder 133 is turned on, and the end of the hydraulic cylinder 133 moves with the welding gun 134. The welding gun 134 first welds the front end of the steel coil. After welding a small part, it moves with the push roller 44 through the driving rod 42 and the moving shaft 43. During the movement of the push roller 44, multiple arc blocks 33 are pressed respectively, so that the limit frame 21 brings the steel coils closer little by little until a pair of steel coils are completely close, thereby improving the firmness of the steel coil welding.

[0030] During welding, the welding area is in a molten state. Initially, the steel coils are close to each other. Once part of them is in a molten state, they squeeze each other to make the bond between the two stronger. After welding for a short distance, the push roller 44 approaches the first arc block 33, and only then does it start to push the steel coil to move.

[0031] Example 2: The difference between Example 2 and Example 1 is that the following technical features are added: Figure 6-7The side end of the arc block 33 is provided with a locking component 5, which includes a first clamping sleeve 51 fixedly connected to the side end of the arc block 33, and a plurality of second clamping sleeves 52 corresponding to the first clamping sleeve 51 are fixedly connected to the side end of the support plate 31. During the movement of the arc block 33, the corresponding first clamping sleeve 51 is clamped with the second clamping sleeve 52; the outer ring of the second clamping sleeve 52 is fixedly sleeved with an annular clamping ring 53, a slot is provided on the first clamping sleeve 51, and a telescopic part 55 is provided on the inner wall of the slot. A pull rod 54 is movably provided at the top of the telescopic part 55, and a limiting block 56 is provided at the bottom of the telescopic part 55. The annular clamping ring 53 moves to the side end of the limiting block 56 to complete the clamping.

[0032] Specifically, the telescopic member 55 includes a fixed tube 551, which is fixedly connected to the inner wall of the slot hole. The inner wall of the fixed tube 551 is slidably connected with a slide rod 552. A telescopic spring 553 is fixedly connected between the slide rod 552 and the fixed tube 551. The top end of the slide rod 552 is fixedly connected to the bottom end of the pull rod 54. Pulling the pull rod 54 can move the slide rod 552. A pull plate is commonly connected between the multiple pull rods 54. Pulling the pull plate can move multiple pull rods 54 at the same time.

[0033] When the first arc block 33 moves, the arc block 33 moves with the first clamping sleeve 51, so that the limit block 56 gradually approaches the annular retaining ring 53. The limit block 56 is lifted up by squeezing the annular retaining ring 53, and the telescopic spring 553 is squeezed, and finally the second clamping sleeve 52 is clamped into the interior of the first clamping sleeve; subsequently, only the pull plate needs to be pulled to lift the multiple sliding rods 552 through the pull rod 54, so that the annular retaining ring 53 is separated from the limit block 56, and under the action of the reset member 32, the limit member returns to its initial position.

[0034] Example 3: The difference between Example 3 and Example 2 is that the following technical features are added: Figure 8 A rolling component 6 is provided at the bottom of the hydraulic cylinder 133. The rolling component 6 includes a driven rod 61 provided at the bottom of the driving frame 45. A rolling roller 62 is provided at the end of the driven rod 61. The rolling roller 62 extrude the weld pool after extrusion to make its surface smooth.

[0035] When part of the steel coil is close to each other, the rolling roller 62 starts to roll and rolls the part to effectively ensure that the welding area is smooth and has no convex spots.

The finished products with embedded grooves enter the packaging machine through the horizontal platform for packaging and storage.

[0037] The head of the opened strip coil enters the shearing machine for head shearing and is introduced into the looper device. When the previous coil of strip steel has entered the looper for storage, its tail enters the shearing machine for tail shearing, and the sheared tail enters the butt welding machine; then the next coil of strip steel that has been opened is loaded, its head enters the shearing machine for head shearing, and is butt welded with the tail of the previous coil of strip steel to achieve continuous production.

[0038] According to different requirements including the specifications of the pre-processed products, the roller die pass profiles of each pass and the temperature of the medium frequency heating device are configured to carry out the pre-embedded channel forming process: the strip enters the first roller die forming machine to continuously bend the raw strip into a channel-shaped cross-section, enters the medium frequency induction heating device to adjust and control the temperature; enters the second roller die forming machine to achieve edge thickening, enters the third roller die forming machine to achieve intermediate forming and tooth rolling at the double edge thickening parts, and enters the fourth roller die forming machine to complete the forming of the pre-embedded channel; The formed embedded channel enters a three-turkish head straightening machine for straightening to ensure the straightness of the product; The pre-embedded channel forming process is specifically performed by configuring the roller die pass profile and the temperature of the medium frequency heating device for each pass. The strip steel enters the first roller die forming machine and is continuously bent in 8 passes to form a channel steel cross section. It enters the medium frequency induction heating device to heat the initially formed channel steel to 1000℃ in preparation for the next process; it enters the second roller die forming machine, which has a total of 2 passes to deform and thicken the two edges of the heated channel steel; the residual temperature of the edge-thickened channel steel is 600℃, and it enters the third roller die forming machine to realize intermediate forming and tooth rolling at the double-edge thickening parts, and enters the fourth roller die forming machine to complete the forming of the embedded channel. The fourth roller die has a total of 10 passes.

[0039] The formed embedded groove enters three Turkish head four-roller straightening machines for straightening to ensure the straightness of the product; Transmission method: Two DC motors (Jiangsu Wangpai) transmit power to the spiral parachute transfer case through two reducers (Jiangsu Guomao), and then transmit it to each flat roller through the universal joint.

[0040] Specifically, after being cut to a fixed length, the product is output to an output roller table for output, and further comprises a transverse platform and a baler. The pre-buried groove finished product enters the baler through the transverse platform for packaging and storage.
