Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel bar processing technology, specifically a steel bar welding equipment. Background Technology
[0002] In many industries such as modern architecture, machinery manufacturing, and bridge construction, steel bar connection is an extremely critical construction step. As one of the main connection methods, steel bar welding plays a decisive role in ensuring the stability and safety of the structure.
[0003] Traditional welding equipment mostly relies on manual hand-held welding guns for welding. If the steel bars are not cleaned before welding, impurities such as oil, rust, and dust on the surface of the steel bars may hinder the fusion of metals during welding. Impurities will produce gas at the high temperature of welding. These gases will form pores in the weld. The presence of pores will reduce the effective cross-sectional area of the weld, resulting in gaps or slag inclusions at the weld, leading to weak welds and safety hazards such as breakage during use.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 3 As shown in the embodiment of this utility model, a steel bar welding device includes a base plate 1; two sets of symmetrically arranged support legs 12 are fixedly connected to the top of the base plate 1; a workbench 13 is fixedly connected to the top of the support legs 12; a welding gun body 14 is fixedly connected to the top of the workbench 13; a limiting groove is formed on the top of the workbench 13 near the welding gun body 14; two sets of symmetrically arranged placement grooves 15 are formed in the middle of the limiting groove; a first spring 17 is fixedly connected to the middle of the placement groove 15; a cleaning brush 16 is fixedly connected to the middle of the first spring 17; a first motor 18 is fixedly connected to the side wall of the workbench 13 near the limiting groove; a first lead screw 19 is rotatably connected to the output end of the first motor 18; two symmetrically arranged first elastic clamps 110 are slidably connected to the middle of the first lead screw 19; a guide is fixedly connected to the middle of the welding gun body 14 away from the cleaning brush 16. The guide tube 11 is equipped with a wire feeding assembly at its end; a collecting assembly is installed at the bottom of the worktable 13; during operation, the reinforcing bar is placed in the middle of the first elastic clamp 110, the first motor 18 is started, and the output end of the first motor 18 drives the first lead screw 19 to rotate. The thread in the middle of the first lead screw 19 can cause the first elastic clamp 110 to move the reinforcing bar towards the middle when it rotates. During the movement, the cleaning brush 16 is used to clean the surface of the reinforcing bar. The first spring 17 can make the cleaning brush 16 adapt to reinforcing bars of different diameters. After cleaning, the welding gun body 14 is started to weld the joint. Through the above structure, oil stains, rust, dust and other impurities on the surface of the reinforcing bar can be effectively removed, the cleanliness of the reinforcing bar surface can be improved, and the presence of impurities can be avoided to prevent problems such as porosity and slag inclusion during welding, thereby improving the strength and stability of the welding operation and ensuring the welding quality.
[0026] like Figure 2As shown, a limiting groove is formed on the top of the workbench 13 near the cleaning brush 16; a second motor 2 is fixedly connected to the side wall of the workbench 13 near the limiting groove; a second lead screw 21 is rotatably connected to the output end of the second motor 2; a slider 22 is slidably connected to the middle of the second lead screw 21; two symmetrically arranged first telescopic rods 23 are fixedly connected to the top of the slider 22; a connecting rod 24 is fixedly connected to the output end of the first telescopic rod 23; a second elastic clamp 25 is fixedly connected to the bottom of the connecting rod 24; during operation, after the steel bar welding is completed, the second motor 2 is started. Its output end drives the second lead screw 21 to rotate, which allows the slider 22 to slide along a predetermined route. After sliding to a suitable position, the first telescopic rod 23 is opened, so that the second elastic clamp 25 contacts the steel bar and grabs it. At this time, the second motor 2 is started again to move the steel bar to the collection component for collection. Through the above structure, the welded steel bar can be picked up quickly and accurately without manual handling. This not only avoids the possibility of workers being burned by the welded steel bar, but also prevents the problem of micro-cracks or other quality defects at the weld joint of the steel bar due to improper picking.
[0027] like Figure 4 As shown, the collection assembly includes a collection box 3; two sets of symmetrically arranged slide rails are installed on the bottom of the workbench 13 near the second placement box 5; the collection box 3 is slidably connected to the middle of the slide rails; multiple equally spaced grooves 31 are opened in the middle of the collection box 3; a second spring 32 is fixedly connected to the middle of the groove 31; a limiting block 33 is fixedly connected to the top of the second spring 32 and works in conjunction with the groove 31; during operation, welded or pre-welded steel bars can be placed in the middle of the collection box 3 through the limiting block 33. At this time, the weight of the steel bars will cause the limiting block 33 to overcome the elastic force of the second spring 32 and slide up and down in the middle of the groove 31, so that the steel bars can be stably placed in the middle of the collection box 3, which is convenient for the steel bars to be taken out. Through the above structure, the cooperation of the second spring 32 and the limiting block 33 can effectively keep the steel bars at a suitable height, which is convenient for taking out and storing. It can also make the collection box 3 accommodate steel bars of different quantities and specifications, which improves the convenience of operation.
[0028] like Figure 3As shown, the wire feeding assembly includes a first placement box 4; the end of the guide tube 11 is fixedly connected to the first placement box 4; the top of the first placement box 4 is fixedly connected to a third motor 41; the output end of the third motor 41 is rotatably connected to a fixing rod; the middle of the fixing rod is detachably connected to a fixing clamp 42; during operation, the welding wire is placed tightly and orderly in the middle of the fixing clamp 42 and connected to the welding gun body 14. At this time, the third motor 41 is started, and its output end drives the fixing clamp 42 and the welding wire in the middle to be conveyed. When welding stops, the third motor 41 is started again, so that the fixing clamp 42 can retract the welding wire. Through the above structure, the welding wire can be effectively delivered to the welding position, improving the welding speed. The stable supply of welding wire is conducive to maintaining a uniform and stable welding operation, and the waste of welding wire can also be avoided.
[0029] like Figure 3 As shown, a second placement box 5 is fixedly connected to the top of the base plate 1 near the first placement box 4; a plurality of equally spaced take-up drums 51 are fixedly connected to the middle of the second placement box 5; a limiting plate 52 is detachably connected to the middle of the take-up drum 51; during operation, welding wires of different materials and sizes can be wound around the middle of the take-up drum 51, and after winding, the limiting plate 52 can be used to limit it to prevent the welding wire from loosening. Through the above structure, it can effectively prevent the welding wire from being piled up randomly and causing pollution and oxidation due to contact with the outside world, and can also avoid the problem of welding operation being affected by the welding wire being loose and tangled.
[0030] like Figure 1 As shown, two symmetrically arranged second telescopic rods 6 are fixed to the side wall of the base plate 1 away from the second placement box 5; the output end of the second telescopic rod 6 is slidably connected to a support rod 61. During operation, the position of the support rod 61 can be precisely adjusted according to the size and length of the reinforcing bar to ensure that the support rod 61 remains stable when supporting the reinforcing bar. Through the above structure, the reinforcing bar can always remain stable during welding operations, avoiding welding defects caused by the shaking and displacement of the reinforcing bar.
[0031] like Figure 1 As shown, a rubber pad 7 is fixed to the top of the support rod 61. During operation, the rubber pad 7 can increase the friction between the support rod 61 and the reinforcing bar, preventing the reinforcing bar from slipping. Through the above structure, the reinforcing bar can be effectively prevented from slipping due to the vibration generated during welding, ensuring that the position of the reinforcing bar remains stable.
[0032] During operation, the reinforcing bar is placed in the middle of the first elastic clamp 110. The first motor 18 is started, and its output end drives the first lead screw 19 to rotate. The thread in the middle of the first lead screw 19 allows the first elastic clamp 110 to move the reinforcing bar towards the center during rotation. During this movement, the cleaning brush 16 cleans the surface of the reinforcing bar. The first spring 17 allows the cleaning brush 16 to adapt to reinforcing bars of different diameters. After cleaning, the welding gun body 14 is started to weld the joint. After the reinforcing bar is welded, the second motor 2 is started, and its output end drives the second lead screw 21 to rotate, allowing the slider 22 to slide along a predetermined path. After sliding to the appropriate position, the first telescopic rod 23 is opened, allowing the second elastic clamp 25 to contact and grip the reinforcing bar. At this time, the second motor 2 is started again to move the reinforcing bar to the collection component for collection. Welded or pre-welded reinforcing bars can be placed in the collection component via the limiting block 33. In the middle of box 3, the weight of the reinforcing bar will cause the limiting block 33 to overcome the elastic force of the second spring 32 and slide up and down in the middle of the slide groove 31, so that the reinforcing bar can be stably placed in the middle of the collection box 3 for easy access. After the welding wire is placed tightly and orderly in the middle of the fixing clamp 42, it is connected to the welding gun body 14. At this time, the third motor 41 is started, and its output end drives the fixing clamp 42 and the welding wire in the middle to be conveyed. When welding stops, the third motor 41 is started again, so that the fixing clamp 42 can retract the welding wire. Welding wires of different materials and sizes can be wound in the middle of the winding drum 51. After winding, the limiting plate 52 can be used to limit it to prevent the welding wire from loosening. The position of the support rod 61 can be precisely adjusted according to the size and length of the reinforcing bar to ensure that the support rod 61 remains stable when supporting the reinforcing bar. The rubber pad 7 can increase the friction between the support rod 61 and the reinforcing bar when supporting the reinforcing bar to prevent the reinforcing bar from slipping.
