Description

Technical Field

[0001] This utility model belongs to the field of welding equipment technology, and specifically relates to a steel strip alignment welding machine. Background Technology

[0002] Steel strip refers to a conveyor belt made of carbon steel, which serves as the traction and carrying component of a belt conveyor and can also be used to bundle goods. It is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of different industrial sectors for the industrialized production of various metal or mechanical products. Since the production line for steel strip needs to operate continuously, and the steel strip obtained after the steel coil is uncoiled is not a continuous steel strip, it needs to be welded end to end by a steel strip welding machine to meet the requirements of the steel strip production line.

[0003] In current technologies, when welding two rolls or strips of steel, the steel strips are usually moved manually for alignment. However, the ends of the steel strips may be irregular, affecting the welding quality. This requires manual cutting, aligning, and adjusting the position of the steel strips multiple times, making the entire welding process cumbersome and inconvenient. It can also easily cause the steel strips to become skewed during operation, resulting in poor welding quality and affecting the quality of the subsequent welded rolls. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A steel strip alignment welding machine, comprising:

[0006] The stand has a welding torch assembly at the bottom that acts on the steel strip;

[0007] The shearing and cutting mechanism cuts off the ends of the steel strip;

[0008] A welding clamping assembly is matched with the welding gun assembly. The welding clamping assembly is located on the side of the shearing flat end mechanism and is connected to the frame.

[0009] Clamping components are symmetrically arranged on both sides of the execution end of the shearing flat end mechanism and connected to the frame. The clamping components clamp the steel strips that are placed on the same line respectively.

[0010] A first moving component is used to drive at least one of the clamping component and the welding pressure component to slide towards or away from the shearing flat mechanism.

[0011] Furthermore, the clamping assembly includes a pair of parallel upper and lower clamping plates and a clamping cylinder that drives at least one of the upper and lower clamping plates to move along the vertical distance between them so that the upper and lower clamping plates move closer to or further apart from each other.

[0012] Furthermore, a second moving component is also connected to the platform to drive the clamping components to move closer or further apart.

[0013] Furthermore, the first moving component and the second moving component include a slide rail and a telescopic component.

[0014] Furthermore, the telescopic component includes a cylinder or a screw mechanism.

[0015] Furthermore, a movable module is also connected to the stand to drive the welding torch assembly to slide along the stand surface.

[0016] Furthermore, a control terminal is provided on the side of the platform.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] The method employs a shearing and flattening mechanism, a welding pressure assembly, a clamping assembly, and a welding torch assembly. The operation of these assemblies is triggered by a first moving assembly and a second moving assembly, resulting in the continuous operation of shearing the ends of two steel strips flat, bringing them closer together, and welding them into a single unit. This process only requires placing the steel strips once, ensuring that the ends of the two sets of steel strips are aligned upon contact. This avoids the situation where the steel strips become skewed due to multiple positioning and movement processes, as seen in existing welding machines. This technical solution improves the welding effect and efficiency of the two sets of steel strips, and ensures the quality of the finished product welded into coils. Attached Figure Description

[0028] like Figure 1 - Figure 5 As shown, the present invention provides a steel strip alignment welding machine, which includes a frame 1, a shearing and flattening mechanism 3, a welding pressing assembly 4, a clamping assembly 5, and a first moving assembly 60.

[0029] A control terminal 8 is provided on the side of the platform 1, and the control terminal 8 has multiple start buttons;

[0030] Among them, the bottom of the frame 1 is equipped with a welding gun assembly 2 that acts on the steel strip;

[0031] The shearing and flat-end mechanism cuts off the ends of three pairs of steel strips.

[0032] The welding clamping assembly 4 is matched with the welding gun assembly 2. The welding clamping assembly 4 is located on the side of the shearing flat end mechanism 3 and is connected to the stand 1.

[0033] The clamping components 5 are symmetrically arranged on both sides of the execution end of the shearing flat end mechanism 3 and connected to the frame 1. The clamping components 5 clamp the steel strips placed on the same line respectively.

[0034] The first moving component 60 is used to drive at least one of the clamping component 5 and the welding pressure component 4 to slide towards or away from the shearing flat mechanism.

[0035] The process employs a shearing and flattening mechanism 3, a welding pressure assembly 4, a clamping assembly 5, and a welding torch assembly 2. The operation of these components is triggered by a first moving assembly 60 and a second moving assembly 61, resulting in the continuous operation of shearing the ends of two steel strips flat, bringing them closer together, and welding them into a single unit. This process only requires placing the steel strips once, ensuring that the ends of the two sets of steel strips are aligned upon contact. This avoids the situation where the steel strips become skewed due to multiple positioning and movement processes, as is common in existing welding machines. This technical solution improves the welding effect and efficiency of the two sets of steel strips, and ensures the quality of the finished product welded into coils.

[0036] Specifically, the clamping assembly 5 includes a pair of parallel upper clamping plates 50 and lower clamping plates 51, and a clamping cylinder that drives at least one of the upper clamping plates 50 and lower clamping plates 51 to move along the vertical distance between them so that the upper clamping plates 50 and lower clamping plates 51 move closer to or further away from each other.

[0037] In addition, a second moving component 61 is connected to the platform 1 to drive the clamping components 5 to move closer or further apart.

[0038] The slide rail 52 and telescopic component and clamping cylinder in the first moving component 60 and the second moving component 61 mentioned above can be adopted as screw mechanism or other structures with telescopic function, such as cylinder, etc., without specific restrictions.

[0039] This flux features automatic shearing and flat-end displacement welding of steel strips, with a processing time of 30–45 seconds for a single workpiece.

[0040] In use, the steel strip is manually placed between the upper clamping plate 50 and the lower clamping plate 51. The foot switch next to the frame 1 (not shown in the figure) is stepped on, and the clamping cylinder 53 at the top of the clamping component 5 retracts or extends, clamping one of the clamping components 5. The foot switch is stepped on again, and the other clamping component 5 clamps. The start button is pressed, and the shearing and flattening mechanism 3 begins to shear and flatten the lower end of the steel strip.

[0041] The effective stroke of the clamping cylinder 53 is not less than 15mm. To ensure the effectiveness of the clamping assembly 5 in clamping the steel strip, the lengths of the upper clamping plate 50 and the lower clamping plate 51 are not less than 115mm.

[0042] Subsequently, the first moving component 60, such as a cylinder, retracts, causing the clamping component 5 and the two sets of steel strips to slide away from the shearing and flat-end mechanism 3. Meanwhile, the second moving component 61 extends or shortens, bringing the ends of the two steel strips that have been sheared closer together to form a pre-welded gap.

[0043] Simultaneously, the first moving component 60 connected to the welding clamping assembly 4 extends, and the welding clamping assembly 4 slides to the upper end of the two steel strip ends. A cylinder (not shown in the diagram) is installed at the top of the welding clamping assembly 4. The cylinder retracts or extends, causing the pressure plate in the welding clamping assembly 4 to apply downward pressure to the ends of the two steel strips, preventing the steel strips from warping and becoming misaligned during the operation of the lower welding gun assembly 2, which would affect the welding quality. After welding is completed, all components return to their initial state, the clamping assembly 5 opens, and the steel strips are manually removed, ultimately welding the two independent steel strips 9 together.

[0044] This welding clamping assembly 4 ensures that the ends of the two sets of steel strips are in a relatively parallel state when they come into contact, thereby guaranteeing the alignment of the two sets of steel strips and improving the subsequent welding effect.

[0045] The platform 1 is also connected to a moving module 7 that drives the welding torch assembly 2 to slide along the surface of the platform 1. The welding torch working end of the welding torch assembly 2 extends upward from the bottom of the platform 1 into the upper surface of the platform 1 and cooperates with the welding pressure assembly 4.

[0046] The welding torch assembly 2 and the moving module 7 mentioned above are both existing technologies. For specific structures and connection methods, please refer to the technical solutions mentioned in relevant technical documents. The above structures are not within the protection scope of this application.
