Abstract

The invention relates to a roll forming processing method for online punching and a production line in the technical field of sheet roll forming. The method comprises the following steps of: emptying, leveling, punching, roll forming, cutting and blanking. The punching step comprises the following specific steps of: detecting a real-time displacement signal of the linear motion of a sheet; driving a punching mechanism to move at an accelerated speed according to the displacement signal and drive the sheet to a set punching position along the movement direction of the sheet; driving the punching mechanism to track the linear motion of a coiled sheet and keep moving synchronously with the sheet; in a process of keeping synchronous movement with the sheet, allowing the punching mechanism to punch a hole at the set position on the sheet; and returning the punching mechanism to an initial position. The invention also provides the production line for implementing the method. Punching is performed after a servo motor controlled by a programmable logic controller (PLC) drives a workbench to track the sheet. The processing method and the production line can improve sheet processing accuracy and increase sheet processing speed and can be used for molding, punching and processing sheets with fixedly shaped cross sections.

Description

technical field

[0001] The invention relates to a processing method and equipment for roll forming of sheet material, in particular to a processing method and equipment for roll forming requiring punching on the sheet material. Background technique

[0002] In the prior art, there is a roll forming production line, which mainly includes a discharge rack, a feeding leveling mechanism, a roll forming machine, a cutting device and a blanking device arranged in sequence. The end of the sheet material is sent to the leveling mechanism for leveling, and then the sheet material enters the roll forming machine in turn to be formed. After forming, it is cut off by the cutting device, and then falls on the blanking device. These formed sheets are punched. When processing holes, it needs to be processed on punching or drilling equipment. Because the sheet has been deformed, it brings certain difficulties to the punching process; because the sheet is continuous before cutting, when the ...
