Embodiment 1

[0028] At room temperature, three frames are used for forming, and the forming angles of each frame are 30°, 60°, and 90° in turn, and the frame spacing is 250mm. The forming material is Dogal 800DP, the section is a symmetrical U-shaped section, the length of the plate is 600mm, the width is 72.32mm, the thickness is 1.2mm, and the forming corner radius R is 1.5mm. The forming speed was set at 5 m / s.

[0029] After the plate comes out of the roll, the plate will rebound, and the rebound angle detected by the machine vision detection device is 1.29°, such as Figure 5 Shown in 30. The data detected by the machine vision detection device is calculated by a specific algorithm to obtain the straightening angle of the roll of the calibration device. The control mechanism controls the motor to drive the worm 8 to rotate, and then drives the worm wheel 9 and the cage 29 to slide along the guide rail 10 to adjust the angle of the adjustable frame. The bending angle of the plate is ...

Abstract

The invention discloses a multi-roller flexible roll formation calibrating device with an adjustable roll angle, which belongs to the field of roll forming technology and equipment, and is used for controlling resilience of a roll forming product. The roll formation calibrating device consists of a frame, a guide rail, an adjustable frame and a drive mechanism thereof, wherein the guide rail is fixed on the frame; the adjustable frame is fixed on the guide rail; and when the resilience is controlled, the drive mechanism can drive the adjustable frame to adjust the roll angle. The multi-rollerflexible roll formation calibrating device has the advantage that the producing accuracy requirement of a product can be better fulfilled by adjusting the roll angle, and is convenient to operate, and is safe and reliable.

Description

technical field [0001] The invention relates to a multi-roller flexible roll forming calibration device with adjustable roll angle, which belongs to the field of roll forming technology and equipment and is used for controlling the rebound of roll forming products. Background technique [0002] Roll forming is an efficient and low-cost sheet forming technology. In recent years, advanced high-strength steel has been more and more widely used. Due to the high hardening rate of this material, especially the control of forming springback, it has become a difficult point in roll forming of advanced high-strength steel. Therefore, it is imperative to control the springback of roll-formed products. [0003] The existing technology generally adopts the mold compensation method to control the springback of the plate. The traditional roll forming springback control method usually needs to shut down the equipment completely or partially, and make the product offline to control the sp...
