Description

Technical Field

[0001] The invention belongs to the technical field of high-strength alloy template punching, and in particular relates to alloy U-plate multi-group punching equipment. Background Art

[0002] At present, in the construction field and the construction process of high-speed railway bridges, high-strength alloy U-plates and scaffolding are gradually replacing wooden formwork and aluminum formwork scaffolding. Aluminum formwork is expensive (about 600 yuan per square meter), and aluminum alloy is easy to stick to dust, and wave lines and bulging appear. High-strength alloy U-plates greatly reduce the use of wood in construction and reduce the waste of resources. High-strength alloy U-plates (about 220 yuan per square meter) can be reused many times and can be recycled. During the construction process, high-strength alloy U-plates are flexible and fast to assemble, and the size matching degree is high, which greatly improves the construction speed and construction quality.

[0003] The material of high-strength alloy U-plate is S550GD galvanized aluminum-magnesium, which is similar to the strength and rigidity of aluminum formwork of the same square. The reaction degree of high-strength steel formwork with concrete is weaker than that of aluminum alloy, and it does not stick to dust and can be directly washed with a high-pressure water gun. High-strength alloy U-plate is formed by laser welding, and the width ranges from 100-400mm. As the most important component, the alloy U-plate is often punched on one side and then manually adjusted to punch the other side. The web punching is completed on another mechanical equipment, which requires a turnover trolley. After multiple operations, the punching accuracy and the distance between holes are difficult to guarantee. Multiple changes in specifications require manual adjustment. Often, the first two pieces need to be measured and then the mold is adjusted after the change, which will produce unqualified products with inappropriate adjustment and finally mass production.

[0004] To sum up, how to provide alloy U-plate multi-group punching equipment can solve many problems in the production and use of high-strength alloy U-plates, and simultaneously complete automatic feeding, clamping, bidirectional multi-row punching, and multi-row web punching on one device, while reducing costs and reducing the difficulty of operation for staff, has become a problem that needs to be urgently solved by technical personnel in this field.
