Double-curvature plate roller bending forming device

Abstract

The invention provides a double-curvature plate roller bending forming device, and belongs to the field of mechanical engineering. The device is mainly composed of at least one row of multiple roller pressing units at the upper portion, at least two rows of multiple lower work roller units at the lower portion, and a rack. Each roller pressing unit is composed of a pressing mechanism, a work roller self-adaptation and transmission mechanism and a supporting body, wherein the pressing mechanism is mainly composed of a pressing hand wheel, a screw, a threaded sleeve and a pressing base, the work roller self-adaptation and transmission mechanism is composed of a clamping ring shaft, a center ball pair and a work roller, and the supporting body is composed of an upper supporting roller, an inner frame and a lower supporting roller. A rigidity bearing and transmission structure is adopted in the whole double-curvature plate roller bending forming device, so that the double-curvature plate roller bending forming device has high bearing capability, and the large-power torque can be input. Compared with other disclosed flexible roller bending forming devices, the double-curvature plate roller bending forming device can form large-size plates with the moderate thickness, and meanwhile the stability in the pressing adjusting process is improved.

Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to a double curvature plate roll forming device. Background technique [0002] At present, the processing of traditional large-size hyperbolic plates is mainly realized through two ways. One is water and fire bending, but the equipment is not easy to automate, the investment cost of automation equipment is high, and it is not easy to achieve accurate forming process control; the other is flexible multi-point mold forming, but this method can only be used for long-scale plates segment by segment Forming, slow speed and low efficiency. Therefore, the roll forming technology has more advantages for the double curvature plate forming process. It not only has high forming efficiency, but also the process parameters are easy to adjust. Chinese Authorized Patent Publication No. CN100379501C discloses a double curvature plate forming device using bendable flexible rollers. This devi...

Problems solved by technology

However, its structure is relatively complicated, and the swing axis and rotating axis of the work roll are not on the same plane, so the work roll tends to move relative to the plate during the contact process, and it is easy to lose stability during the pressing adjustment process
