Description

technical field [0001] The invention relates to cladding equipment for composite stainless steel pipes. Background technique [0002] As a decorative material, composite stainless steel pipes have been widely used to make stair handrails, shelves and handrails for vehicles and ships, furniture, lamps and public facilities. Composite stainless steel pipes are composed of carbon steel pipes in the inner layer and stainless steel in the outer layer. The production materials are carbon steel pipes and stainless steel strips, and the thickness of the stainless steel strips is roughly 0.3 mm. Composite stainless steel pipe production requires composite stainless steel pipe cladding equipment, the existing composite stainless steel cladding equipment includes drive mechanism, carbon steel uncoiler, stocker, carbon steel forming machine, high frequency welding machine, weld seam grinder, carbon Steel sizing machine, stainless steel strip uncoiler, composite stainless steel pipe for...

Problems solved by technology

The Chinese Patent Publication No. CN1635300 discloses a stainless steel clad non-circular pipe and its processing method and processing equipment. It starts the non-circular pipe rolling mill to cold-roll the circular pipe into a non-circular shape, and then longitudinally Straightening, using small deformation and linear deformation rolls, can ensure the same rolling deformation rate in each pass, changing the previous cold rolling deformation law of first large and then small; adopting transmission straightening method, eliminating the front and rear of stainless steel non-circular tubes The problem of thickening at the end of the tube is solved, and the bottom diameter of the roll is increased step by step to keep the speed of the roll and the pipe in sync, which overcomes the defect that the existing technology cannot process stainless steel composite non-circular tubes for a long time

Applying the structure and principle of the stainless steel clad non-round pipe processing equipment of the above invention patent to the cladding equipment for cladding stainless steel pipes in the existing assembly line to produce composite stainless steel pipes, it is only suitable for the production of composite stainless steel pipes with an oval cross-section in the assembly line , and the current market demand is a lot of composite stainless steel pipes with a rectangular cross-section, and the existing composite stainless steel pipe cladding equipment for producing composite stainless steel pipes with a rectangular cross-section, the specifications and lengths of carbon steel pipes have been finalized, production The composite stainless steel pipe with a rectangular cross section is prone to slippage between the carbon steel pipe and the outer stainless steel. We must add welding points at both ends of the composite stainless steel pipe, and the production capacity is low. When different users require different specifications and When the cross-section of the length is rectangular, the delivery period is often delayed, and it is not even possible to provide
