Description

Technical Field

[0001] The invention belongs to the technical field of anti-skid chain production, and in particular relates to an anti-skid chain pressurized butt welding device. Background Art

[0002] Anti-skid chains are made of a series of chain links that are linked one by one to form a metal bar chain. They are necessary items for safe driving of cars with anti-skid functions. Generally, they protect tires and prevent them from slipping on snowy and muddy roads, thereby ensuring the normal driving of the vehicle.

[0003] Anti-skid chains are a device widely used in vehicle tires to enhance driving safety. One of the key steps in their manufacturing process is to firmly press and weld the ends of the chains to ensure the stability and durability of the chains under extreme conditions.

[0004] At present, when welding anti-skid chains, traditional welding equipment usually uses pneumatic lockers or hydraulic lockers to clamp the chain firmly to achieve the purpose of welding, but these devices are difficult to ensure the absolute stability of the chain during the welding process. Since these locking devices often only provide local or instantaneous pressure and cannot maintain the stability of the chain for a long time, this directly leads to unsatisfactory fastening effect of the chain end during welding, and it is easy to loosen after welding, which seriously affects the overall performance and safety reliability of the anti-skid chain. In addition, when applying pressure, traditional welding equipment often has the problem of uneven pressure distribution. This uneven pressure application may not only cause the materials at the welding site to fail to fully fuse, but also may cause stress concentration at the welding interface, thereby increasing the risk of cracks at the welding site. In some cases, even if no obvious defects appear in the short term, it will gradually loosen due to stress accumulation under long-term use, eventually affecting the performance and life of the anti-skid chain. Therefore, there are deficiencies and it cannot meet the production and use needs of manufacturers. Therefore, it is necessary to further improve it.

At this time, the rotating clamp 40 responds quickly to stably clamp and accurately position the anti-skid chain passing by. Subsequently, the electric retractor 23 is driven to generate kinetic energy and operate through the precise control of the external program. The piston rod on the electric retractor 23 is used to push the clamping plate 25 and the clamping part 26 to move relative to each other, and the clamping plate 25 slides stably on the slide bar 24 while moving, which can improve the stability of the clamping plate 25 when moving. With the continuous movement of the clamping plate 25, the clamping plate 25 is driven to drive the clamping part 26 to fix and clamp the anti-skid chain to be welded, and the clamping part 26 can firmly clamp and fix the anti-skid chain to be welded, and the synergistic effect of the rotating clamp 40 and the clamping assembly 20 can achieve accurate positioning and stable clamping of the anti-skid chain. In addition, when the clamping part 26 moves relatively to clamp the anti-skid chain, since the first pressurizing component 51 and the second pressurizing component 52 are provided on the clamping part 26, when the first pressurizing component 51 and the second pressurizing component 52 contact each other, the locking column 512 on the first locking block 511 is driven to insert into the locking groove 5211 in the second locking block 521, and in the process of the locking column 512 inserting into the locking groove 5211, the locking column 512 will come into contact with the inductive movable bevel block 73 and push it to move toward the inside of the inductive shell 71, so as to make the first electrode sheet 74 and the second electrode sheet 75 fit and contact, and send out an electrical signal to drive the electromagnet ring 522 to be energized to generate magnetism, and the magnetic force of the electromagnet ring 522 after being energized can be used to The locking iron sheet 513 is firmly adsorbed, and the first locking block 511 and the second locking block 521 are closely adsorbed with the locking iron sheet 513 through the electromagnet ring 522, thereby achieving a strong pressurized fixing effect, thereby enhancing the locking force of the anti-skid chain, which effectively prevents the anti-skid chain from loosening during the welding process, ensures the firmness of the welded joint, and thus improves the overall quality of the anti-skid chain; and by arranging a plurality of groups of pressurizing mechanisms 50 on the clamping portion 26, a strong and uniform pressurizing force on the anti-skid chain can be achieved by utilizing the symmetrically distributed first pressurizing components 51 and the second pressurizing components 52, and such uniform pressurizing force can promote good pressing of the chain ends, thereby forming a good welded joint, and reducing the risk of damage to the anti-skid chain; When the locking column 512 is inserted into the locking groove 5211, the locking column 512 will contact the cooling movable inclined block 83 and push it to move toward the inside of the cooling shell 81, and then use the second movable plate 82 to push the cooling head 84 outward and align the cooling head 84 with the anti-skid chain to be welded; at the same time, through the precise control of the external program, the driving cylinder 32 generates kinetic energy to operate, and the piston rod of the driving cylinder 32 is used to push the welding gun 35 to move above the anti-skid chain to be welded, and then the welding gun 35 is used to weld the anti-skid chain; In addition, when the locking column 512 is inserted into the locking groove 5211, the extrusion block 5122 will contact the damping protrusion 523 on the inner wall of the locking groove 5211. The damping force when the extrusion block 5122 contacts the damping protrusion 523 can compress the elastic rod 5123. When the locking column 512 is fully inserted into the locking groove 5211, the elastic force of the elastic rod 5123 pushes the extrusion block 5122 to move, and the extrusion block 5122 pushes the extrusion plate 62 to squeeze the cooling airbag 61, so that the cooling airflow in the cooling airbag 61 is transmitted along the ventilation pipe 63. The cooling air is input to the cooling head 84, and then the cooling ball 85 is used to spray the cooling airflow onto the anti-skid chain being welded, so as to cool down the anti-skid chain; and in the process of the airflow flowing through the cooling head 84, the force of the airflow flows to hit the force-bearing plate 93, driving the swing frame 92 to generate an up and down vibration frequency under the action of the vibration spring 95, and then the vibration fork 94 knocks the cooling ball 85, so that the cooling ball 85 changes its angle back and forth under the knocking force of the vibration fork 94, and forms a sweeping shape with an up and down angle, thereby increasing the cooling range of the anti-skid chain.
