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

Embodiment Construction

[0033] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0034] The invention provides a double-curvature plate roll forming device.

[0035] Such as figure 1The above is a schematic diagram of the core part of the double-curvature plate roll forming device. A row of five rolling units 1 is arranged on the upper part, and two rows of five driven roller-type lower working roller units 3 are arranged in parallel on the lower part. According to the shape of the three-dimensional curved surface to be processed, first, adjust the reduction amount of each reduction mechanism by computer or manually, and adjust the height of the work rolls, so that the work rolls are arranged into the required curve. The effect is that the upper row of rolling unit 1 presses down the plate, and under the joint action of the two row...

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...
