Description

Technical Field

[0001] This application relates to the field of strip processing technology, and in particular to a strip shearing and welding machine. Background Technology

[0002] In modern industrial production, strip material, as an important basic material, is widely used in many fields such as electronics, machinery, automobiles, and packaging. Depending on the design and manufacturing process requirements of different products, the length of the strip needs to be cut or spliced. For example, in the production of automotive parts, the strip may need to be cut to specific lengths to fit different components, while in the production of large mechanical parts, multiple shorter strips may need to be welded together to meet dimensional requirements.

[0003] Currently, strip processing is typically divided into two separate steps: shearing and welding. Shearing is usually done by specialized shearing equipment, while welding requires welding equipment. This separate processing method presents several problems. First, the switching between equipment leads to low production efficiency, increasing production time and costs. Second, manual operation during shearing and welding is prone to errors, resulting in inaccurate strip length or inconsistent welding quality, thus affecting product quality and reliability. Furthermore, separate equipment requires more production space, increasing production costs and management complexity.

[0004] To address the aforementioned issues, integrated processing equipment has emerged in the market. Relevant existing technologies, such as the Chinese patent application "Strip Welding Machine" (application number CN201210371429.2), disclose a system comprising an electrical control cabinet, a welding mechanism mounted on top of the cabinet, a trimming mechanism mounted to the right of the welding mechanism, and a cutting mechanism for cutting the strip. The welding mechanism includes a strip feeding wheel, a positioning cylinder for positioning the strip during welding, a copper strip feeding wheel, a servo motor for driving the copper strip feeding wheel, a copper strip cutter, a welding cylinder, a welding fixing plate, and a welding rod. The direction of copper strip feeding by the copper strip feeding wheel is perpendicular to the direction of the strip feeding wheel. This strip welding machine of the present invention can save working time in welding strips and improve work efficiency.

[0005] However, most existing equipment can only perform shearing or welding in a single direction, and there is still room for improvement in terms of automation, precision control, and ease of operation. Therefore, this application aims to provide a strip shearing and welding machine that can achieve precise shearing and high-quality welding of strips on an integrated platform, meeting different production and processing needs, improving production efficiency, reducing production costs, and ensuring product quality stability. Utility Model Content

[0006] The technical problem to be solved by this application is to provide a strip shearing and welding machine, which achieves efficient and flexible strip processing through symmetrical shearing components and integrated shearing and welding design, thereby improving production efficiency and welding quality.

[0007] The technical solution adopted in this application is as follows: a strip shearing and welding machine, including a frame, the frame being provided with a welding assembly, a left shearing assembly and a right shearing assembly, the structure of the left shearing assembly being symmetrical to the structure of the right shearing assembly, the welding assembly being located between the left shearing assembly and the right shearing assembly, the left shearing assembly including a conveying assembly, a centering assembly and a punching assembly arranged in sequence, the welding assembly including a welding substrate, a welding torch and an adjustable mounting frame, the welding substrate and the adjustable mounting frame being respectively disposed on the frame, the welding substrate being provided with a reference groove, the welding torch being mounted on the adjustable mounting frame, the adjustable mounting frame being operated to drive the welding torch to move, the welding torch being positioned directly opposite the reference groove.

[0008] Compared with existing technologies, the advantages of this application are as follows: First, the left and right shearing components are structurally symmetrical and located on both sides of the welding component. This design allows for flexible selection of the shearing direction according to actual production needs, enabling efficient completion of the shearing task whether processing the strip from left to right or right to left.

[0009] Secondly, by integrating the welding assembly, left shearing assembly, and right shearing assembly onto a single frame, continuous processing of strip shearing and welding is achieved. Compared to traditional separate equipment, this integrated design reduces changeover time between machines and eliminates the need for manual strip handling, thereby significantly improving production efficiency. For example, in automotive parts manufacturing, the entire process from strip shearing to welding can be completed on the same machine, eliminating the need for multiple loading, unloading, and transfers, greatly shortening the production cycle.

[0010] Furthermore, the adjustable mounting bracket design allows for flexible adjustment of the welding torch position according to different strip sizes and welding requirements. The reference groove provides a precise positioning reference for welding, ensuring that the welding torch can be accurately aligned with the welding point. This design not only improves welding flexibility but also guarantees the stability of weld quality.

[0011] Finally, compared to traditional multi-unit equipment combinations, this integrated design significantly reduces the floor space required for the equipment. Within a limited production space, space resources can be utilized more efficiently, reducing production costs.

The structures of the left shearing assembly 3 and the right shearing assembly 4 are symmetrical. The welding assembly 2 is located between the left and right shearing assemblies 3 and 4. This design allows for flexible selection of the shearing direction according to actual production needs, efficiently completing the shearing task whether processing the strip 36 from left to right or right to left. Integrating the welding assembly 2, left shearing assembly 3, and right shearing assembly 4 onto a single frame 1 enables continuous processing of the strip 36 for shearing and welding. Compared to traditional separate equipment, this integrated design reduces changeover time between devices and avoids manual handling of the strip 36, thereby significantly improving production efficiency.

[0036] The left shearing assembly 3 includes a conveying assembly 5, a centering assembly 6, and a punching assembly 7 arranged sequentially. The welding assembly 2 includes a welding substrate 8, a welding torch 9, and an adjustable mounting frame 10. The welding substrate 8 and the adjustable mounting frame 10 are respectively mounted on the frame 1. The welding substrate 8 has a reference groove 11. The welding torch 9 is mounted on the adjustable mounting frame 10. The operation of the adjustable mounting frame 10 drives the welding torch 9 to move, with the welding torch 9 positioned directly opposite the reference groove 11. The design of the adjustable mounting frame 10 allows the position of the welding torch 9 to be flexibly adjusted according to the size of different strips 36 and welding requirements. The reference groove 11 provides a precise positioning reference for welding, ensuring that the welding torch 9 can accurately align with the welding point. This design not only improves the flexibility of welding but also ensures the stability of welding quality.

[0037] Compared to traditional multi-unit equipment combinations, this integrated design significantly reduces the equipment's footprint. Within limited production space, space resources can be utilized more efficiently, reducing production costs.

[0038] Both sides of the welding assembly 2 are provided with pressure plates 34, which are connected to a third pressure cylinder 35.

The rotary motor 16 is connected to the lower pressure roller 13, and the rotary motor 16 drives the lower pressure roller 13 to rotate. The position of the upper pressure roller 12 is fixed by a first pressure cylinder 15, which applies a certain pressure to the feed belt 36 through the upper pressure roller 12. Under the predetermined pressure, the rotary motor 16 drives the lower pressure roller 13 to rotate, and the rotation of the lower pressure roller 13 drives the feed belt 36 to move.

The sensor can feed the data back to the control system, realizing automated control and reducing errors from manual measurement.

[0042] The second pressure cylinder 18 operates to move the counting wheel 20 to a predetermined position. The counting wheel 20 contacts and connects with the material belt 36.
