Abstract
Description
Technical Field
[0001] This application relates to the field of steel strip processing technology, and more specifically to a high-efficiency welding device for a continuous steel strip production line. Background Technology
[0002] When processing and using steel strips, two or more rolls need to be welded together to form a single unit. Currently, the welding process involves first cutting the beginning and end of the two rolls of steel strips, then placing the strips on the welding table so that the joints are directly below the welding torch. A hydraulic device is then used to press the beginning and end of the two rolls for positioning, followed by welding by moving the welding torch. In this process, the alignment of the joints directly below the welding torch is crucial to the welding result. Currently, this process requires manual operation. The operator must hold the beginning and end of each roll with both hands, moving them while observing the joint position through the welding table. This alignment is difficult, prone to human error, leading to a high scrap rate and causing significant operator fatigue. Utility Model Content
[0003] In view of the above problems, this application provides an efficient welding device for a continuous steel strip production line, which can help adjust the position of the butt joint between two rolls of steel strip so that it is directly below the welding gun.
[0004] According to one aspect of the embodiments of this application, a high-efficiency welding device for a continuous steel strip production line is provided. The high-efficiency welding device for a continuous steel strip production line includes a support frame, on which a shearing groove and a welding groove are sequentially arranged. A welding table is arranged above the welding groove, and an upper pressure plate is connected to the lower part of the welding table via a lifting assembly. Multiple moving blocks are slidably arranged below the upper pressure plate. A receiving groove is formed below the welding groove on the support frame, and a positioning traction component is arranged within the receiving groove. The positioning traction component includes a horizontally arranged guide rail component. Two traction blocks are slidably and symmetrically arranged on the top of the guide rail component. A positioning assembly is arranged at one end of each of the two traction blocks that are close to each other. Two L-shaped rotating plates are hinged to the sides of the guide rail component on both sides of the two traction blocks. A first waist hole and a second waist hole are formed at the two ends of the L-shaped rotating plates, respectively. The sides of the traction blocks are slidably connected to the inside of the first waist hole via a first sheath shaft. A telescopic rod is vertically arranged at the bottom of the guide rail component, and a lifting plate is connected to the top of the telescopic rod. The sides of the lifting plate are slidably connected to the inside of the second waist hole via two second sheath shafts.
[0005] In some embodiments, the positioning assembly includes two T-shaped support plates connected to both sides of the top of the lifting plate, and two U-shaped top rods hinged to the T-shaped support plates. The middle part of the U-shaped top rod is hinged to the T-shaped support plate, one end of the U-shaped top rod extends to the top of the traction block, and the other end is connected to the T-shaped support plate by a compression spring.
[0006] In some embodiments, the two U-shaped top rods located on the two traction blocks and on the same side are staggered.
[0007] In some embodiments, a plurality of sliding grooves are provided below the upper pressure plate, the movable block is slidably connected in the sliding groove, the bottom of the sliding groove extends from the lower part of the movable block and is connected to an anti-slip pad, a guide rod is fixedly connected to the inner side wall of the sliding groove, the guide rod passes through the movable block, and a return spring is sleeved on the outer periphery of the guide rod at the inner side wall of the movable block and the sliding groove.
[0008] In some embodiments, a reciprocating moving component is provided at the welding table, and a welding torch is connected to the reciprocating moving component.
[0009] In some embodiments, a hydraulic shear is provided at the cutting groove.
[0010] In some embodiments, a movable steel rail is provided below the bracket, and the bracket is slidably mounted on the movable steel rail.
[0011] The beneficial effects of this application are as follows: By setting up an upper pressure plate, a positioning traction component, and a moving block, etc., the two butt joint ends of the steel strip to be welded can be positioned so that the two butt joint ends stop after contacting the positioning component. At this time, the two butt joint ends are at the same position from the welding torch. Then, by cooperating with components such as the telescopic rod, the traction block drags the two butt joint ends towards each other and moves synchronously to complete the butt joint. At this time, the butt joint of the two steel strips will be just below the welding torch, thereby improving the yield rate in the subsequent welding process. In this application, by setting up an upper pressure plate and setting a moving block at the bottom of the upper pressure plate, the moving block can work together with the traction block to clamp the steel strip. On the other hand, when the traction block moves, the moving block can move synchronously under the action of friction, so that the moving block always abuts and presses against the top of the steel strip, thereby keeping the steel strip in a flat state.

Figure 6This application provides a partial structural diagram of the lifting plate and positioning components in an embodiment. The high-efficiency welding device 100 for a continuous steel strip production line includes a support 110. A shearing groove 111 and a welding groove 112 are sequentially arranged on the support 110. Typically, for ease of operation, the shearing groove 111 is located below the welding groove 112. The steel strip needs to be sheared at the shearing groove 111 to flatten its ends before being fed into the welding groove 112 for welding. A hydraulic shear is typically installed at the shearing groove 111 for shearing. Since shearing is not a core inventive point of this application, it will not be described in detail here; however, please refer to existing technology for details. A welding table 120 is arranged above the welding groove 112. A welding torch 125 is typically installed at the welding table 120, which is used to weld the butt joint between two steel strips below. Below the welding table 120, an upper pressure plate 122 is connected via a lifting assembly 121. Driven by the lifting assembly 121, the upper pressure plate 122 presses down, pressing onto the two steel strips to keep them flat. The lifting assembly 121 can be a hydraulic cylinder. Multiple movable blocks 123 are slidably arranged below the upper pressure plate 122. These blocks abut against the top of the steel strips to keep them flat. Simultaneously, when the traction block 132 moves the steel strips, friction exists between the movable blocks 123 and the steel strip, allowing the blocks to move along with the strips. A receiving groove 113 is provided below the welding groove 112 at the support 110. A positioning and traction component 130 is installed within the receiving groove 113. This component positions the beginning and end of the steel strips and pulls the two rolls of steel strips towards each other to complete the docking. The positioning and traction component 130 includes a horizontally arranged guide rail component 131. Two traction blocks 132 are slidably and symmetrically arranged on the top of the guide rail component 131. A positioning component 133 is provided at one end of the two traction blocks 132 that is close to each other. The positioning component 133 is used to block the end of the steel strip. When the operator inserts the steel strip (the two steel strips are inserted from right to left and from left to right respectively) into the welding groove 112, the end of the steel strip will be blocked by the positioning component 133. At this time, the ends of the two steel strips are at the same distance from the orthographic projection position of the welding torch 125.Two L-shaped rotating plates 134 are hinged to both sides of the guide rail component 131 on both sides of the two traction blocks 132. The two ends of the L-shaped rotating plates 134 are respectively provided with a first waist hole 134a and a second waist hole 134b. The two sides of the traction blocks 132 are slidably connected to the inside of the first waist hole 134a through the first sheath shaft 135. A telescopic rod 136 is vertically provided at the bottom of the guide rail component 131. A lifting plate 137 is connected to the top of the telescopic rod 136. The two sides of the lifting plate 137 are slidably connected to the inside of the second waist hole 134b through two second sheath shafts 138. The telescopic rod 136 can extend and retract. During the movement of the telescopic rod 136, it can drive the lifting plate 137 to move. During the movement of the lifting plate 137, it can further drive the L-shaped rotating plates 134 to move through the second sheath shafts 138. The L-shaped rotating plates 134 will further drive the traction blocks 132 to move.
[0024] In the operation of this embodiment, after the first and last ends of the two rolls of steel strip are cut in the cutting groove 111, the front and rear ends of the two rolls of steel strip are inserted into the welding groove 112 from the left and right ends respectively, until the ends of the steel strip are blocked by the positioning component 133 and then stop. At this time, the lifting component 121 drives the upper pressure plate 122 to press down, and the steel strip will be squeezed between the moving block 123 and the traction block 132. At this time, the telescopic rod 136 drives the lifting plate 137 to move down, and the four second pins move down with the lifting plate 137. During the downward movement of the second sheath shaft 138, it slides inside the second waist hole 134b and drives the L-shaped rotation. The plate 134 is flipped over, and the first waist hole 134a moves further, pushing the first sheath shaft 135 to move. Simultaneously, the first sheath shaft 135 pushes the two traction blocks 132 closer to each other. At this time, the two traction blocks 132 will drive the steel strip on its top and the moving block 123 squeezed on the top of the steel strip to move together, so that the ends of the two steel strips are close together and abut. At this time, the welding equipment on the welding table 120 can be turned on for welding. After the welding is completed, the lifting component 121 is reset and drives the upper pressure plate 122 to move up. After the steel strip is removed, the telescopic rod 136 moves up and simultaneously drives the traction blocks 132 and other components to reset for the next work.
[0025] As can be seen from the above, in this embodiment, by setting the upper pressure plate 122, the positioning traction component 130 and the moving block 123 to cooperate with each other, the two joint ends of the steel strip to be welded can be positioned so that the two joint ends stop after contacting the positioning component 133. At this time, the two joint ends are at the same position from the welding gun 125. Then, by cooperating with the telescopic rod 136 and other components, the traction block 132 drags the two joint ends to move towards each other and synchronously to complete the joint. At this time, the joint seam of the two steel strips will be just below the welding gun 125, thereby improving the yield of the subsequent welding process. In this application, the upper pressure plate 122 is also set and the moving block 123 is set at the bottom of the upper pressure plate 122 so that the moving block 123 can work together with the traction block 132 to clamp the steel strip. On the other hand, when the traction block 132 moves, the moving block 123 can move synchronously under the action of friction, so that the moving block 123 always abuts and presses against the top of the steel strip, thereby keeping the steel strip in a flat state.
[0026] In some embodiments, the positioning component 133 includes two T-shaped support plates 133a connected to both sides of the top of the lifting plate 137, and two U-shaped top rods 133b hinged to the T-shaped support plates 133a. The middle part of the U-shaped top rod 133b is hinged to the T-shaped support plate 133a. One end of the U-shaped top rod 133b extends to the top of the traction block 132, and the other end is connected to the T-shaped support plate 133a through a compression spring 133c. This application embodiment illustrates a specific arrangement of the positioning component 133. In this embodiment, when placing the steel strip, one end of the U-shaped rod extends slightly above the traction block 132. When the steel strip is placed, it will slide along the top of the traction block 132, while one end of the U-shaped rod is higher than the top of the traction block 132. Therefore, the traction block 132 will be blocked and positioned by the U-shaped rod. When the upper pressure plate 122 is pressed down, the telescopic rod 136 returns to its original position downwards, and the traction block 132 drives the steel belt to move. At this time, the lifting plate 137 drives the T-shaped support plate 133a and the U-shaped top rod 133b to fall. When the steel belt moves with the traction block 132, it will first push the U-shaped top rod 133b to press the compression spring 133c and then flip over. The steel belt can move without being affected. Then, when the U-shaped top rod 133b falls with the lifting plate 137 and disengages from the steel belt, the U-shaped top rod 133b flips over and returns to its original position again.
[0027] In some embodiments, two U-shaped top rods 133b located on the two traction blocks 132 and on the same side are staggered.
[0028] In some embodiments, a plurality of sliding grooves 122a are provided below the upper pressure plate 122. The moving block 123 is slidably connected in the sliding groove 122a. The bottom of the sliding groove 122a extends from the lower part of the moving block 123 and is connected to an anti-slip pad 123a. The anti-slip pad 123a is used to enhance the friction between the moving block 123 and the steel strip and prevent the steel strip from slipping between the moving block 123. A guide rod 122b is fixedly connected to the inner side wall of the sliding groove 122a. The guide rod 122b is disposed through the moving block 123. A return spring 122c is sleeved on the outer periphery of the guide rod 122b at the inner side wall of the moving block 123 and the sliding groove 122a. In this embodiment of the application, with the above settings, when the traction block 132 drives the connecting ends of the two steel strips to approach each other, the sliding block will squeeze the reset spring 122c and move by relying on the friction between the steel strip and the sliding block. After the welding is completed, the lifting assembly 121 drives the upper pressure plate 122 to move up and reset, and the sliding block loses contact with the steel strip. At this time, the sliding block will be reset under the action of the reset spring 122c to facilitate the next work.
[0029] In some embodiments, a reciprocating moving assembly 124 is provided at the welding table 120, and a welding torch 125 is connected to the reciprocating moving assembly 124. For ease of explanation, this application embodiment provides a specific arrangement of the welding torch 125 at the welding table 120. During operation, the reciprocating moving assembly 124 drives the welding torch 125 to move along the extension direction of the butt joint between the two steel strips, thereby completing the welding of the entire butt joint.
[0030] In some embodiments, a hydraulic shear is provided at the cutting groove 111. In this embodiment, the hydraulic shear provided at the cutting groove 111 can cut the steel strip flat, which is convenient for subsequent welding.
[0031] In some embodiments, a movable steel rail 140 is provided below the support 110, and the support 110 is slidably mounted on the movable steel rail 140. In this embodiment, through the above-described arrangement, the movable steel rail 140 allows the support 110 to move to the conveying area of the steel strip, thereby facilitating the welding of the steel strip.
