Description

Technical Field

[0001] The present invention belongs to the field of welding machines, and more particularly to a high-strength alloy template welding machine. Background Art

[0002] In the field of building construction such as houses, in order to ensure that the concrete can form a shape that meets the design requirements during the solidification process, temporary support structures are required. Among them, the application of using specific-shaped steel materials (such as U-shaped plates, etc.) as formwork supports is very extensive. The quality and performance of such support formworks are directly related to the forming accuracy and safety of the building structure.

[0003] Currently, there are mainly two processing techniques for the production of such support formworks as U-shaped plates in China.

[0004] Traditional roll forming process

[0005] Process principle: The first process uses high-strength steel with a thickness of 1.5 mm for each of the A, B, and C surfaces (such as Figure 4 , with a strength of 750 MPa), and directly processes the sheet into a U-shaped profile through multiple passes of roller rolling, and then performs a cutting operation.

[0006] Material and equipment limitations:

[0007] Material performance bottleneck: The extrusion forming process has strict requirements for the elongation of the material. Under the current domestic high-strength steel technical conditions, in order to ensure that the material does not crack during the roll forming process, the balance point between the elongation and strength of the steel allows the steel strength to only reach 750 MPa. However, in actual construction sites, especially the A and C surfaces of the U-shaped plate as the main stress-bearing parts, this strength level is difficult to meet the construction requirements of high load and high safety.

[0008] Equipment level differences: The quality of roll forming equipment varies, resulting in difficult precise control of the R value of the bending outer angle at points E and F during the roll forming process, and often the R value is too large. This not only affects the overall shape accuracy of the U-shaped plate, but also makes the splicing gap between the two plates too large during subsequent splicing use, unable to meet the strict requirements of the high-standard wall pouring for the formwork sealing and forming accuracy, and easily causes problems such as concrete leakage and uneven wall surface, thereby affecting the construction quality.

[0009] Advantages and production capacity bottlenecks of the group welding process

[0010] Process improvement and advantages: Given the limitations of the roll forming process, some enterprises have started to adopt the group welding process for production. This process decomposes the U-shaped plate into three parts: the A and C side panels and the B bottom plate. The side panels use high-strength steel with a thickness of 2.0 mm and a strength of 750 MPa to enhance the overall strength of the product, especially to meet the high-strength requirements of the A and C surfaces during construction. Since the bottom plate does not require bending operations, high-strength steel with a low elongation rate but a strength of up to 1100 MPa is used, effectively solving the problem of excessive outer R corners during the roll forming process while ensuring structural strength, and improving the forming accuracy and splicing quality of the product.

[0011] Shortcomings of welding equipment: Although the products produced by the group welding process can meet all the pain points of customers in terms of performance, the current domestic welding equipment technology is not yet mature, which has become the key factor restricting the large-scale popularization and application of this process. Existing welding equipment has obvious deficiencies in production efficiency, dimensional accuracy control, and welding quality stability, resulting in limited production capacity. The welding area per person per day does not exceed 20 square meters, unable to meet the large demand for formwork support materials in large-scale construction projects. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033] As Figure 1 shown:

[0034] Embodiment 1: The present invention provides a high-strength alloy template welding machine, including a workbench 1, an uncoiler and straightening mechanism 2, a set of cold bending forming mechanisms 3, a set of guiding mechanisms 4 and an electric welding mechanism 5. The uncoiler and straightening mechanism 2 is fixedly installed at one end of the upper side of the workbench 1, the electric welding mechanism 5 is fixedly installed at the other end of the upper side of the workbench 1, a set of cold bending forming mechanisms 3 are symmetrically and fixedly installed at the middle position of the upper side of the workbench 1, and a set of guiding mechanisms 4 are symmetrically and fixedly installed on the upper side of the workbench 1 and close to the electric welding mechanism 5;

[0035] Among them, the uncoiler and straightening mechanism 2 adopts a common strip steel straightening machine, mesh plate straightening machine or steel plate straightening machine in the market;

[0036] The cold bending forming mechanism 3 adopts a roller pressing method to bend the strip steel two 200 into a required shape;

[0037] A set of guiding mechanisms 4 adopt a roller guiding method to guide the movement of the strip steel one 100 and the strip steel two 200;

[0038] The electric welding mechanism 5 adopts a common electric welding machine in the market. When the strip steel one 100 and the strip steel two 200 move at a constant speed, the welding position will be continuously updated, so as to achieve the effect of continuous welding;

[0039] When the strip steel one 100 is sent to the workbench 1, the strip steel one 100 is straightened by the uncoiler and straightening mechanism 2;

[0040] When the strip steel two 200 is sent to the workbench 1, the strip steel two 200 is shaped by a set of cold bending forming mechanisms 3;

[0041] A set of shaped strip steel two 200 is guided to both sides of the straightened strip steel one 100, and the strip steel one 100 and the strip steel two 200 are guided to approach each other through a set of guiding mechanisms 4, and are welded through a welding mechanism 5.

[0042] As can be seen from the above, when the strip steel one 100 is sent to the workbench 1, it is first straightened by the uncoiling and straightening mechanism 2;

[0043] At the same time, the strip steel two 200 is also sent to the workbench 1 and is shaped by a set of cold bending forming mechanisms 3;

[0044] The shaped strip steel two 200 is then guided by a set of guiding mechanisms 4 to both sides of the straightened strip steel one 100;

[0045] Finally, through the further guidance of the guiding mechanism 4, the strip steel one 100 and the strip steel two 200 approach each other and are welded through the welding mechanism 5, and the welding position is Figure 3 at S in, thereby fixing the strip steel two 200 to both sides of a set of strip steel one 100.

[0046] Such as Figure 2 shown:

[0047] Embodiment 2: This embodiment is basically the same as the previous embodiment, the difference is that the guiding mechanism 4 includes a pressure roller 41 fixedly installed on the workbench 1 and a set of guiding rollers 42;

[0048] The pressure roller 41 presses down and limits the strip steel one 100;

[0049] A set of guiding rollers 42 straighten the strip steel two 200.

[0053] A set of correction wheels 6 guide the combined strip steel one 100 and strip steel two 200, and the cutting mechanism 7 cuts the combined strip steel one 100 and strip steel two 200.

[0054] Specifically, several limiting frames 8 are also fixedly installed on the workbench 1;

[0055] The limiting frame 8 limits the strip steel one 100.

[0056] As can be seen from the above, the strip steel 1 - 100 and the strip steel 2 - 200 after being welded and fixed are guided by a set of calibration wheels 6 and reach the position of the cutting mechanism 7. The cutting mechanism 7 cuts the combined strip steel 1 - 100 and strip steel 2 - 200 to meet specific length requirements.
