Description

Technical Field

[0001] This utility model relates to the field of saw blade processing technology, and more specifically, to a laser welding device for bimetallic band saw blades. Background Technology

[0002] The bimetal band saw blade laser welding device is a specialized processing equipment for bimetal band saw blades. Its core technology utilizes laser energy to achieve a high-strength metallurgical bond between two dissimilar metals, solving problems such as low strength and large deformation that often occur with traditional welding. The device consists of a laser generator, a motion control system, and an optical transmission system. During operation, the saw blade and workpiece are first clamped and fixed together by a positioning fixture. Then, the laser generator outputs a high-energy laser beam, which is focused by the optical system and applied to the joint, instantly heating the local metal to a molten state, forming a weld pool. Simultaneously, argon gas is introduced into the protective gas system to isolate the weld pool from air and prevent oxidation. Under the continuous action of the laser, the atoms of the two metals fully diffuse and fuse, forming a metallurgical bonding layer. After welding, this lays the foundation for subsequent processing and cutting of the saw blade. Since the workpiece docking efficiency directly affects the welding effect and operational efficiency, it is necessary to perform a welding docking operation on the saw blade.

[0003] In related technologies, during the use of welding equipment, workers typically place two saw blade workpieces to be welded inside the fixture, align the saw blade workpieces, and then clamp and fix the saw blade workpieces using the fixture for use.

[0004] However, during the current use of welding equipment, when workers hold the saw blade and workpiece to place and connect them, they need to repeatedly move and adjust the position of the saw blade and workpiece to connect them. This can easily lead to deviations at the connection point of the saw blade and workpiece, resulting in welding deviations in the subsequent saw blade and workpiece, which affects the convenience of the welding equipment's connection operation and the welding effect.

[0020] Reference Figures 1-4This utility model provides a technical solution: a bimetallic band saw blade laser welding device, including a welding machine 1 and a workpiece docking mechanism. A welding torch 2 is installed on the top of the welding machine 1, and pressure heads 3 are installed on both sides of the top of the welding machine 1. The two sides of the top of the welding machine 1 can form a reference for docking the saw blade workpieces, so that the user can place the two saw blade workpieces to be welded into the top of the welding machine 1. This avoids the situation where it is difficult to dock the saw blade workpieces when using the welding machine 1, which would lead to inconvenience in docking the saw blade workpieces and affect the welding effect. Therefore, it improves the docking operation convenience and welding effect of the welding machine 1.

[0021] Reference Figures 1-4 In a preferred embodiment, the workpiece docking mechanism includes a docking seat 4, which is movably connected to both sides of the top of the welding machine 1. A docking frame 5 is fixedly connected to the rear side of the outer side of the top of the docking seat 4. A translation groove 6 is formed at the bottom of the docking seat 4. Translation rails 7 located inside the translation groove 6 are fixedly connected to both sides of the top of the welding machine 1. A translation adjustment mechanism is fixedly connected to the inner side of the front side of the docking seat 4. According to the size of the external saw blade workpiece, the docking seat 4 is moved by hand to adjust the docking reference range between the docking seats 4. At this time, the translation rails 7 move inside the translation groove 6 to perform translation connection between the docking seat 4 and the welding machine 1. Then, the workpiece is moved by hand. The external saw blade workpiece is placed on top of the docking seat 4, so that the rear side of the outer side of the saw blade workpiece contacts and abuts against the inner side of the docking frame 5, thus enabling the docking operation between the saw blade workpieces. The translation adjustment mechanism includes an adjustment seat 8, a screw hole 9, and a double-ended screw 10. The adjustment seat 8 is fixedly connected to the inner side of the front side of the docking seat 4, the screw hole 9 is opened on the inner side of the adjustment seat 8, and the double-ended screw 10 is threaded into the inside of the screw hole 9. This provides the user with a medium to adjust the position between the docking seats 4, so that the user can simultaneously adjust the working position of the translation seats on both sides of the top of the welding machine 1, avoiding the situation where the docking seats 4 are difficult to adjust during use, thus improving the convenience of the adjustment operation of the translation seats.

[0022] Reference Figures 2-3 In a preferred embodiment, operating seats 11 are fixedly connected to both sides of the top of the welding machine 1. An operating handle 12 is movably connected inside the operating seat 11. The inner side of the operating handle 12 is fixedly connected to the outer side of the double-ended screw 10, which provides the user with a force-applying medium for rotating the double-ended screw 10. This avoids the situation where it is difficult to apply force when using the double-ended screw 10, thus improving the ease of operation of the double-ended screw 10. Support seats 13 are fixedly connected to both sides of the top of the welding machine 1. A support groove 14 is opened on the inner side of the support seat 13. The double-ended screw 10 is located inside the support groove 14, which can provide working support and prevent deviation between the double-ended screw 10 and the welding machine 1, avoiding the situation where the double-ended screw 10 is easily deviated under force during operation, thus improving the working stability of the double-ended screw 10.

[0023] Reference Figures 2-4 In a preferred embodiment, a pressure plate 15 is movably connected to the rear side of the top of the docking seat 4, and an inclined plate 16 is fixedly connected to the front side of the pressure plate 15. This allows for the downward pre-clamping of the saw blade workpiece inside the docking frame 5, preventing the docking frame 5 from being difficult to clamp during use. This improves the clamping effect of the docking frame 5. Connecting frames 17 are fixedly connected to both sides of the rear side of the docking seat 4, and connecting seats 18 are sleeved on the surface of the connecting frames 17. The front side of the connecting seat 18 is fixedly connected to the rear side of the pressure plate 15, allowing for the lifting and lowering connection between the pressure plate 15 and the docking seat 4 to prevent displacement. This prevents the pressure plate 15 from shifting position or even separating from the docking seat 4 during use, thus improving the connection effect between the pressure plate 15 and the docking seat 4.

[0024] Reference Figures 2-4 In a preferred embodiment, a spring 19 located outside the connecting frame 17 is movably connected to the top of the connecting seat 18. One end of the spring 19 is connected to the top of the connecting seat 18, and a fixing plate 20 is threadedly connected to the top of the connecting frame 17. The other end of the spring 19 is connected to the bottom of the fixing plate 20. The connecting seat 18 can apply downward pressure and pre-clamping force to the pressure plate 15, avoiding the situation where it is difficult to apply downward pressure when the pressure plate 15 is working. Therefore, the downward pressure effect of the pressure plate 15 is improved. A sleeve 21 is fixedly connected to the top of the connecting seat 18 and the bottom of the fixing plate 20. The sleeve 21 is located outside the spring 19 and can perform anti-displacement work between the spring 19 and the connecting seat 18 and the fixing plate 20, thus improving the working stability of the spring 19.

[0025] Specifically, the working process or principle of this bimetallic band saw blade laser welding device is as follows: During use, based on the actual dimensions of the external saw blade workpiece and the required welding range, the operator 12, in conjunction with the operating seat 11, rotates the double-ended screw 10. This causes the double-ended screw 10, engaging with the screw hole 9, to pass through the adjusting seat 8, applying a threaded thrust to the docking seat 4, moving it inwards or outwards. Simultaneously, the translation rail 7 moves within the translation groove 6, performing translational connection and anti-displacement work between the docking seat 4 and the welding machine 1. During this process, the operator 12 rotates within the operating seat 11, performing operational anti-displacement work between the double-ended screw 10 and the welding machine 1. At the same time, the support seat 13, in conjunction with the support groove 14, further supports and prevents displacement between the double-ended screw 10 and the welding machine 1. Then, the handheld saw blade workpiece is placed on the docking seat 4. The saw blade workpiece is pushed from the front and rear sides of the top, so that it comes into contact with the inner side of the docking frame 5. At this time, the inclined plate 16 is affected by the backward movement force of the saw blade workpiece. The inclined plate 16 applies an upward pushing force to the pressure plate 15, so that the pressure plate 15 moves upward to cooperate with the docking seat 4 and the docking frame 5 to press down the incoming saw blade workpiece. During this process, the connecting seat 18 moves with the pressure plate 15 on the outside of the connecting frame 17 to perform lifting and lowering connection between the pressure plate 15 and the docking seat 4. At this time, the spring 19, together with the fixed plate 20 and the connecting seat 18, applies a downward pushing force to the pressure plate 15, so that the pressure plate 15 effectively presses down the saw blade workpiece. At the same time, the sleeve 21 and the spring 19 perform anti-displacement work. Then, the saw blade workpiece can be welded by the welding machine 1 and the welding gun 2.

[0026] It should be noted that welding machine 1, welding torch 2 and pressure head 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
