Description
Technical Field
[0001] This utility model relates to the technical field of steel strip butt welding machines, and in particular to a steel strip butt welding machine. Background Technology
[0002] Butt welding machines, also known as current welding machines or resistance welding machines, utilize the resistance between the contact surfaces of two workpieces to instantly pass a low voltage and high current, causing the contact surfaces of the two mating metals to heat up instantly until they melt and fuse. Butt welding machines are often used for welding steel strips.
[0003] The inventors discovered during routine use of the butt welding machine that when welding fixed parts, it is usually necessary to fix the two ends of the fixed parts together so that the two ends of the steel strip are joined together for welding. Since the welding is done by the operator holding the steel strip with their right hand, misalignment of the fixed parts may occur, which can cause problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a steel strip welding machine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel strip butt welding machine, comprising a butt welding machine, a welding head provided on the side of the butt welding machine, a switch provided on the side of the butt welding machine, a fixing clamp provided on the side of the butt welding machine, the fixing clamp being disposed on both sides of the welding head, a locking element rotatably connected to the bottom of the fixing clamp, a motor fixedly connected inside the butt welding machine, a grinding wheel provided on the side of the butt welding machine, the grinding wheel being driven by the motor, an extrusion device provided on the side of the butt welding machine, an alignment device provided on the side of the butt welding machine, the alignment device comprising a rectangular frame fixedly connected to the side of the butt welding machine, a threaded rod rotatably connected inside the rectangular frame, a slider threadedly connected to the surface of the threaded rod, a rectangular strip fixedly connected to the side of the slider, and a fixed plate fixedly connected to the top of the rectangular frame.
[0006] The effect achieved by the above components is as follows: under the action of the threaded rod, the slider moves, thereby clamping and aligning the steel strip to avoid misalignment. When welding the steel strip, the two ends of the steel strip are joined together by the fixing clamp and locking device. Under the action of the alignment device, the steel strip is aligned. Pressing the switch causes the welding head to weld the joint of the steel strip, thereby completing the welding of the steel strip.
[0007] Preferably, a rectangular groove is provided on the side of the slider, and a rotating roller is rotatably connected inside the rectangular groove.
[0008] The effect achieved by the above components is that, under the action of the rotating roller, the steel strip can be moved after being clamped, thereby facilitating the repositioning and alignment of the steel strip and avoiding the phenomenon of separation between the steel strips.
[0009] Preferably, a rectangular plate is fixedly connected to the top of the fixed plate, a rectangular block is fixedly connected to the top of the rectangular plate, a rotating plate is rotatably connected to the side of the rectangular block, a first screw is threadedly connected to the surface of the rotating plate, and a pressing plate is rotatably connected to one end of the first screw.
[0010] The effect achieved by the above components is that, under the action of the first screw, the extrusion plate is pressed against the surface of the steel strip, thus preventing the steel strips from stacking together.
[0011] Preferably, a slide rod is fixedly connected to the top of the extrusion plate, and the slide rod is slidably connected to the surface of the rotating plate.
[0012] The effect achieved by the above components is that, under the action of the slide bar, the extrusion plate will not rotate with the rotation of the first screw.
[0013] Preferably, a locking rod is inserted into the side of the rectangular block, and one end of the locking rod is inserted into the interior of the rotating plate.
[0014] The effects achieved by the above components are as follows: Under the action of the clamping rod, the position of the rotating plate can be adjusted to allow the steel strip to move, thus preventing the rotating plate from rotating. When welding the steel strip is required, the steel strip is placed inside the fixed clamp, and the threaded rod is turned by hand to move the slider towards the fixed plate, thereby clamping the steel strip. The rotating plate is rotated on the side of the rectangular block, thus making the rotating plate overlap with the rectangular plate. Under the action of the clamping rod, the position of the rotating plate can be adjusted to allow the steel strip to move, thus preventing the rotating plate from rotating. The first screw is turned by hand to make the extrusion plate press against the surface of the steel strip, thus preventing the steel strips from overlapping. When the steel strips are not aligned, under the action of the rotating roller, the steel strips can be smoothly displaced and aligned, thus achieving the alignment effect.
[0015] Preferably, the extrusion device includes a square plate fixedly connected to the side of the welding machine, a second screw threadedly connected to the surface of the square plate, and a rectangular plate rotatably connected to one end of the second screw.
[0016] The effect achieved by the above components is that, under the action of the second screw, the rectangular plate can press the welded steel strip onto the surface of the grinding wheel for grinding, thereby achieving the pressing effect.
[0017] Preferably, a round rod is slidably connected to the surface of the square plate, and the round rod is slidably connected to the surface of the square plate.
[0018] The effect achieved by the above components is that, under the action of the round rod, the rectangular plate will not rotate with the rotation of the second screw.
[0019] Preferably, an anti-slip strip is fixedly connected to the bottom of the rectangular plate, and a magnetic plate is fixedly connected to the bottom of the rectangular plate.
[0020] The aforementioned components achieve the following effects: Under the action of the magnetic plate and anti-slip strip, the steel strip can be attracted to the surface of the rectangular plate, thus preventing the steel strip from being displaced by the grinding wheel. When the steel strip is welded and needs to be ground, the welded area is placed on the surface of the grinding wheel, and the second screw is turned by hand. Under the action of the round rod, the rectangular plate will not rotate with the rotation of the second screw, causing the rectangular plate to move down and press against the surface of the steel strip. Under the action of the magnetic plate and anti-slip strip, the steel strip can be attracted to the surface of the rectangular plate, thus preventing the steel strip from being displaced by the grinding wheel. The motor is started, causing the grinding wheel to rotate under the action of the coupling at the motor output end, thereby grinding the welded area on the surface of the steel strip, thus achieving the pressing effect.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting up an alignment device, when welding steel strips, the steel strip is placed inside the fixed clamp, and the threaded rod is turned by hand to move the slider towards the position of the fixed plate, thereby clamping the steel strip. The rotating plate is rotated on the side of the rectangular block, so that the rotating plate overlaps with the rectangular plate. Under the action of the clamping rod, the position of the rotating plate can be aligned with the steel strip, avoiding the phenomenon of the rotating plate rotating. The first screw is turned by hand to press the extrusion plate against the surface of the steel strip, thereby preventing the steel strips from overlapping. When the steel strips are not aligned, under the action of the rotating roller, the steel strips can be smoothly displaced and aligned, thereby achieving the alignment effect. This solves the problem that steel strips are easily misaligned during the alignment process due to the operator's hand operation. Attached Figure Description

[0027] Example 1, such as Figure 1-3 As shown, a steel strip butt welding machine 1 includes a butt welding machine 1, a welding head 7 and a switch on the side of the butt welding machine 1, a fixing clamp 4 on both sides of the welding head 7, a locking member 5 rotatably connected to the bottom of the fixing clamp 4, a motor fixedly connected inside the butt welding machine 1, a grinding wheel 6 driven by the motor on the side of the butt welding machine 1, a pressing device 3 and an alignment device 2 on the side of the butt welding machine 1. When welding the steel strip, the two ends of the steel strip are joined together by the fixing clamp 4 and the locking member 5. Under the action of the alignment device 2, the steel strip is aligned. Pressing the switch causes the welding head 7 to weld the joint of the steel strip, thereby completing the welding of the steel strip. The working principle of the resistance butt welding machine 1 is to heat the contact surface of the workpiece to a plastic state by the resistance heat generated inside the workpiece by the current, and then apply pressure to complete the welding.
[0028] Reference Figure 2The alignment device 2 includes a rectangular frame 21 fixedly connected to the side of the welding machine 1. A threaded rod 22 is rotatably connected inside the rectangular frame 21. A slider 23 is threadedly connected to the surface of the threaded rod 22. A rectangular strip is fixedly connected to the side of the slider 23. A fixed plate is fixedly connected to the top of the rectangular frame 21. Under the action of the threaded rod 22, the slider 23 moves, thereby clamping and aligning the steel strip, avoiding misalignment. When welding the steel strip, the two ends of the steel strip are joined together by the fixing clamp 4 and the locking member 5. Under the action of the alignment device 2, the steel strip is aligned. Pressing the switch initiates the welding process. The first 7 is welded at the joint of the steel strip to complete the welding of the steel strip. A rectangular groove is opened on the side of the slider 23, and a rotating roller 24 is rotatably connected inside the rectangular groove. Under the action of the rotating roller 24, the steel strip can be moved after being clamped, which facilitates the displacement and alignment of the steel strip and avoids the phenomenon of separation between the steel strips. A rectangular plate 25 is fixedly connected to the top of the fixed plate, and a rectangular block is fixedly connected to the top of the rectangular plate 25. A rotating plate 26 is rotatably connected to the side of the rectangular block. A first screw 27 is threadedly connected to the surface of the rotating plate 26, and a pressing plate 29 is rotatably connected to one end of the first screw 27. Under the action of the first screw 27, the extrusion plate 29 is pressed against the surface of the steel strip, preventing the steel strip from stacking together. A sliding rod 28 is fixedly connected to the top of the extrusion plate 29. The sliding rod 28 is slidably connected to the surface of the rotating plate 26. Under the action of the sliding rod 28, the extrusion plate 29 will not rotate with the rotation of the first screw 27. A clamping rod is inserted into the side of the rectangular block. One end of the clamping rod is inserted into the interior of the rotating plate 26. Under the action of the clamping rod, the position of the rotating plate 26 can be adjusted to accommodate the steel strip, preventing the rotating plate 26 from rotating. When it is necessary to weld the steel strip, the steel strip is placed inside the fixing clamp 4 and then manually... Tightening the threaded rod 22 moves the slider 23 towards the fixed plate, thereby clamping the steel strip. The rotating plate 26 rotates on the side of the rectangular block, causing the rotating plate 26 to overlap with the rectangular plate 25. Under the action of the clamping rod, the position of the rotating plate 26 is such that the steel strip can be positioned, preventing the rotating plate 26 from rotating. Tightening the first screw 27 by hand causes the pressing plate 29 to press against the surface of the steel strip, thereby preventing the steel strips from overlapping. When the steel strips are not aligned, the rotating roller 24 allows the steel strips to move smoothly and align together, thus achieving the alignment effect.
[0029] Reference Figure 3The extrusion device 3 includes a square plate 31 fixedly connected to the side of the welding machine 1. A second screw 32 is threadedly connected to the surface of the square plate 31. A rectangular plate 34 is rotatably connected to one end of the second screw 32. Under the action of the second screw 32, the rectangular plate 34 can extrude the welded steel strip onto the surface of the grinding wheel 6 for grinding, thereby achieving the extrusion effect. A round rod 33 is slidably connected to the surface of the square plate 31. Under the action of the round rod 33, the rectangular plate 34 will not rotate with the rotation of the second screw 32. An anti-slip strip 35 is fixedly connected to the bottom of the rectangular plate 34. A magnetic plate 36 is fixedly connected to the bottom of the rectangular plate 34. The magnetic plate 36 and the anti-slip strip 35 interact to form a magnetic strip. The steel strip is attracted to the surface of the rectangular plate 34, thus preventing it from shifting due to the grinding wheel 6. When the steel strip is welded and needs grinding, the welded area is placed on the surface of the grinding wheel 6, and the second screw 32 is turned by hand. Under the action of the round rod 33, the rectangular plate 34 does not rotate with the rotation of the second screw 32, causing the rectangular plate 34 to move down and press against the surface of the steel strip. Under the action of the magnetic plate 36 and the anti-slip strip 35, the steel strip is attracted to the surface of the rectangular plate 34, thus preventing it from shifting due to the grinding wheel 6. The motor is started, causing the grinding wheel 6 to rotate under the action of the coupling at the motor output end, thereby grinding the welded area on the surface of the steel strip and achieving the pressing effect.
[0030] Working principle: When using the steel strip welding machine 1, the steel strip is joined together at both ends by the fixing clamp 4 and locking member 5. Under the action of the alignment device 2, the steel strip is aligned. Pressing the switch causes the welding head 7 to weld the joint of the steel strip, thus completing the welding. The working principle of the resistance welding machine 1 is to use the resistance heat generated inside the workpiece by the current to heat the contact surface of the workpiece to a plastic state, and then apply pressure to complete the welding. When welding the steel strip, the steel strip is placed inside the fixing clamp 4. The threaded rod 22 is turned by hand, causing the slider 23 to move towards the position of the fixed plate, thereby clamping the steel strip. The rotating plate 26 is rotated on the side of the rectangular block, so that the rotating plate 26 overlaps with the rectangular plate 25. Under the action of the clamping rod, the position of the rotating plate 26 can be used for the steel strip, preventing the rotating plate 26 from rotating. The first screw is turned by hand. The screw 27 causes the extrusion plate 29 to press against the surface of the steel strip, thus preventing the steel strips from overlapping. When the steel strips are not joined together, the rotating roller 24 allows the steel strips to move smoothly and join together, thus achieving alignment. When the steel strip is welded and needs to be ground, the welded area is placed on the surface of the grinding wheel 6, and the second screw 32 is turned by hand. Under the action of the round rod 33, the rectangular plate 34 does not rotate with the rotation of the second screw 32, causing the rectangular plate 34 to move down and press against the surface of the steel strip. Under the action of the magnetic plate 36 and the anti-slip strip 35, the steel strip can be attracted to the surface of the rectangular plate 34, thus preventing the steel strip from being moved by the grinding wheel 6. The motor is started, causing the grinding wheel 6 to rotate under the action of the coupling at the motor output end, thereby grinding the welded area on the surface of the steel strip, thus achieving the extrusion effect.
