Description

Technical Field

[0001] This utility model relates to the field of strip steel welding technology, specifically a strip steel head and tail shearing and butt welding device. Background Technology

[0002] Steel strip, also known as strip steel, is a type of steel with a width of less than 1300mm, and its length varies slightly depending on the size of each coil. Steel strip is generally supplied in coils and has advantages such as high dimensional accuracy, good surface quality, ease of processing, and material saving.

[0003] The existing strip shearing and butt welding equipment is inconvenient for unloading and conveying the welded steel strip during use, resulting in a large accumulation of finished steel strip rings under the equipment. This affects the operator's subsequent operations, requiring time to clean up the accumulated finished products before proceeding with the welding work. Consequently, the efficiency of strip welding is reduced, and the delivery speed is affected.

[0004] Therefore, a shearing and welding device for the head and tail of steel strips is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a shearing and welding device for the head and tail of steel strip to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: A shearing and welding device for the head and tail of steel strip includes a base, a device frame welded to the top of the base, a first cavity opened inside the device frame, a first cylinder fixed inside the first cavity by bolts, the output end of the first cylinder extending through the first cavity, a push plate fixed to the output end of the first cylinder by bolts, a first support slide rod welded to one side of the push plate, the first support slide rod slidably installed inside the first cavity, a conveyor belt installed on one side of the top of the base, a motor fixed to one side of the conveyor belt by bolts, and the output end of the motor fixedly connected to the rotating shaft of the conveyor belt.

[0006] Preferably, the equipment frame has a second cavity inside, a second support slide rod is fixedly installed inside the second cavity, a pressure plate assembly is slidably installed on the outside of the second support slide rod, and a third cylinder is fixed inside the second cavity by bolts, and the output end of the third cylinder is fixedly connected to the top of the pressure plate assembly.

[0007] Preferably, the pressure plate assembly includes a sliding plate, one end of which slides out of the second cavity. A pressure plate body is welded to one side of the sliding plate, a welding groove is provided on one side of the pressure plate body, and a rubber anti-slip pad is installed on the bottom of the pressure plate body.

[0008] Preferably, two support plates are welded to one side of the equipment frame, and a positioning block is installed on the top of each of the two support plates.

[0009] Preferably, the top of the equipment frame is fixed with a mounting groove, and a third support slide rod is fixedly installed inside the mounting groove. A second cylinder is installed inside the mounting groove by bolts.

[0010] Preferably, the output end of the second cylinder is fixed with a slider by screws, and the slider is slidably sleeved on the outside of the third support slide rod. The bottom of the slider extends slidably out of the mounting groove, and welding equipment is installed at the bottom of the slider.

[0011] Compared with the prior art, the present invention provides a shearing and butt welding device for steel strip head and tail, which has the following advantages:

[0012] After the strip head and tail are welded, the output end of the third cylinder is controlled to retract, causing the pressure plate to move upward and releasing the pressure on the strip. Then, the output end of the first cylinder is controlled to extend, causing the push plate to move outward. The outward movement of the push plate pushes the welded strip hanging above the support plate onto the conveyor belt. The rotation of the motor output end drives the conveyor belt, thus transferring the strip rings that fall onto the conveyor belt to the other end. This facilitates the collection of welded strip rings, preventing finished products from accumulating below the equipment. This allows operators to operate the equipment for continuous production, improving the efficiency of strip welding and increasing the delivery speed of finished strip rings.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: A device frame 2 is welded to the top of the base 1. A first cavity 3 is opened inside the device frame 2. A first cylinder 4 is fixed inside the first cavity 3 by bolts. The output end of the first cylinder 4 extends through the first cavity 3. A push plate 17 is fixed to the output end of the first cylinder 4 by bolts. A first support slide rod 5 is welded to one side of the push plate 17. The first support slide rod 5 is slidably installed inside the first cavity 3. A conveyor belt 16 is installed on one side of the top of the base 1. A motor 15 is fixed to one side of the conveyor belt 16 by bolts. The output end of the motor 15 is fixedly connected to the shaft of the conveyor belt 16.

[0020] The equipment frame 2 has a second cavity 6 inside, and a second support slide rod 8 is fixedly installed inside the second cavity 6. A pressure plate assembly 7 is slidably installed on the outside of the second support slide rod 8. A third cylinder 18 is fixed inside the second cavity 6 by bolts, and the output end of the third cylinder 18 is fixedly connected to the top of the pressure plate assembly 7.

[0021] The pressure plate assembly 7 includes a slide plate 701, one end of which slides out of the second cavity 6. A pressure plate body 702 is welded to one side of the slide plate 701. A welding groove 704 is provided on one side of the pressure plate body 702. A rubber anti-slip pad 703 is installed on the bottom of the pressure plate body 702.

[0022] Two support plates 14 are welded to one side of the equipment frame 2, and a positioning block 1401 is installed on the top of each of the two support plates 14.

[0023] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when welding the strip steel, after the operator bends and aligns the two ends of the strip steel, the two ends of the strip steel are respectively located above the support plate 14. Since the top of the support plate 14 is equipped with a positioning block 1401, the positioning block 1401 can limit the strip steel. Then, by controlling the extension of the output end of the third cylinder 18, the pressure plate assembly 7 is driven to move downward, thereby controlling the two pressure plate bodies 702 to press the two ends of the strip steel between the pressure plate body 702 and the support plate 14. Since the bottom of the pressure plate body 702 is equipped with a rubber anti-slip pad 703, the rubber anti-slip pad 703 can increase the friction between the bottom of the pressure plate body 702 and the strip steel, thereby ensuring the stability of pressing the strip steel. Then, welding is performed. After welding is completed... Then, by controlling the retraction of the output end of the third cylinder 18, the pressure plate body 702 is moved upward, canceling the pressing of the strip steel. Subsequently, by controlling the extension of the output end of the first cylinder 4, the push plate 17 is moved outward. The outward movement of the push plate 17 can push the welded strip steel hanging above the support plate 14 into the conveyor belt 16. The rotation of the output end of the motor 15 can drive the conveyor belt 16 to transmit the strip steel ring that has fallen above the conveyor belt 16 to the other end, thus facilitating the collection of the welded strip steel ring and preventing the finished products from accumulating below the equipment. This allows the operator to operate the equipment for continuous production, improves the efficiency of strip steel welding, and increases the delivery speed of the finished strip steel ring.

[0024] Example 2: The top of the equipment frame 2 is fixed with a mounting groove 10, and a third support slide rod 11 is fixedly installed inside the mounting groove 10. A second cylinder 9 is installed inside the mounting groove 10 by bolts. A slider 12 is fixed to the output end of the second cylinder 9 by screws. The slider 12 is slidably sleeved on the outside of the third support slide rod 11. The bottom of the slider 12 extends out of the mounting groove 10. A welding device 13 is installed at the bottom of the slider 12.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, by controlling the extension and retraction of the output end of the second cylinder 9, the slider 12 can be driven to slide along the installation direction of the third support slide rod 11. Since the bottom of the slider 12 extends out of the installation groove 10 and the bottom of the slider 12 is fixed with welding equipment 13, the sliding of the slider 12 can drive the welding equipment 13 to slide back and forth. Since a welding groove 704 is provided on one side of the pressure plate body 702, the welding equipment 13 can automatically weld the two ends of the strip steel through the welding groove 704, thereby improving production efficiency.

[0026] Working principle: During use, after the operator bends and aligns the two ends of the steel strip, the two ends of the strip are positioned above the support plate 14. Since the top of the support plate 14 is equipped with a positioning block 1401, the strip can be limited. Then, by controlling the extension of the output end of the third cylinder 18, the pressure plate assembly 7 moves downward, thereby controlling the two pressure plate bodies 702 to press the two ends of the strip between the pressure plate bodies 702 and the support plate 14. Since the bottom of the pressure plate body 702 is equipped with a rubber anti-slip pad 703, the friction between the bottom of the pressure plate body 702 and the strip is increased, thus ensuring the stability of the steel strip pressing. Welding is then performed by controlling the sliding of the slider 12 to drive the welding equipment 13. The strip slides back and forth. Since a welding groove 704 is provided on one side of the pressure plate body 702, the welding equipment 13 can automatically weld the two ends of the strip steel through the welding groove 704, thereby improving production efficiency. After the welding is completed, the pressure plate body 702 is moved upward by controlling the output end of the third cylinder 18 to release the pressure on the strip steel. Then, the push plate 17 is moved outward by controlling the extension of the output end of the first cylinder 4. The outward movement of the push plate 17 can push the strip steel hanging above the support plate 14 and the completed welding into the conveyor belt 16. The rotation of the output end of the motor 15 can drive the conveyor belt 16 to perform transmission, thereby transferring the strip steel ring that has fallen above the conveyor belt 16 to the other end. The above operation can be repeated to continuously produce strip steel rings.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
