Roll bending machine for manufacturing of aluminum alloy profile

Abstract

A roll bending machine for manufacturing of an aluminum alloy profile comprises a bottom plate, a fixed frame, a drive device, a bending device, a limiting block, rolling devices, clamping devices androll wheels. The fixed frame is mounted on the bottom plate and is of a U-shaped structure. Arc through holes are symmetrically formed in the front side of the upper end of the fixed frame. The problems that during existing roll bending machining of manufacturing of the aluminum alloy profile, machining of reducing the rebounding margin cannot be carried out on a round pipe profile subjected to roll bending molding machining, consequently, the rebounding phenomenon happens to the machined round pipe profile, meanwhile, when the round pipe profile is clamped, clamping marks are prone to beinggenerated on the clamped surface of the round pipe profile, consequently, the surface of a round pipe is not smooth, when roll bending machining is started no buffer function is achieved at the clamping position, the phenomena of cracks and bending are prone to being generated due to too large stress of the round pipe profile, and consequently roll bending machining fails can be solved.

Description

technical field [0001] The invention relates to the technical field of profile processing, in particular to a rolling-bending machine for manufacturing aluminum alloy profiles. Background technique [0002] The method of bending the sheet or profile through the rotation of the rotating shaft is called roll forming. The rolling forming method is used in many processing fields. The method of realizing rolling forming is simple and convenient to operate. Tube-shaped structures or arc-shaped components are generally formed by rolling and bending, and high production efficiency, high precision, and stability make them widely used in many processing fields. [0003] At present, there are usually the following deficiencies in the roll-bending process of round pipe profiles: 1. The existing equipment cannot process the round pipe profiles after roll-bending to reduce the springback allowance, resulting in 2. When the existing equipment clamps the round pipe profile, it is easy to m...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem of the inability to reduce the springback margin of the round tube profile after the roll bending process in the existing rolling bending machining of the aluminum alloy profile, resulting in the appearance of the round tube profile after the processing is completed. At the same time, when clamping the round tube profile, it is easy to cause pinch marks on the clamping surface of the round tube profile, resulting in a rough surface of the round tube, and at the beginning of the rolling process, there is no cushioning function at the clamping point. It is easy to break and bend the round tube profile due to excessive force, resulting in failure of rolling bending processing and other problems
