Embodiment

[0025] In this embodiment, the frame P above the hot-pressing plate of the fixed-thickness hot-pressing section 0 ,P 1 ,P 2 ,...,P 7 Arranged in sequence along the direction of the production line, each rack contains a hydraulic cylinder C 1 、C 2 ,...,C 5 .

[0026] After the pre-pressed slab is pressurized at low temperature, it enters the pressurized thickness section, which is controlled by the frame P 1 Set thickness; Rack P required 1 Working in displacement mode, frame P 0 ,P 2 ,...,P 7 Work in the pressure mode; at this time, the production line works in the mutual cooperation mode, and the rack P 1 The active action, the rest of the racks are slave actions, such as image 3 ; at rack P 1 , requires C 2 、C 3 、C 4 Working together in displacement (or pressure) mode, C 1 、C 5 Working in the pressure mode, the rack P at this time 1 Working in self-coordinated mode, C 2 、C 3 、C 4 is an active action, C 1 、C 5 is a driven action, such as Figure 4 ; I...

Abstract

The invention relates to an automatic board shape deviation correction cooperative control method for an artificial board continuous flat pressing fixed-thickness hot-pressing segment. The automatic board shape deviation correction cooperative control method aims at the problems of cooperative control of multiple hydraulic cylinders and board shape deviation correction of a hot pressing board of the continuous flat pressing fixed-thickness hot-pressing segment, large time delay feedback system characteristics of continuous flat pressing process board shape control are comprehensively considered, and a level collaborative control mechanism is proposed to realize automatic board shape deviation correction cooperative control of the artificial board continuous flat pressing.

Description

technical field [0001] The invention belongs to the field of mechanical equipment control, and in particular relates to an automatic plate shape correction collaborative control method for a thickness-setting hot-pressing section in a continuous flat press. Background technique [0002] In the continuous flat press, multiple hydraulic cylinders on the hot plate are distributed in arrays along the direction of the production line and perpendicular to the direction of the production line, and work in groups according to different process modes. In the final section of the hot press, that is, the fixed-thickness hot-pressing section, if the hydraulic cylinders cannot work well together, the product will have plate shape problems such as uneven thickness of the plate surface; if the detection and feedback of the plate shape problem is not timely, it will be Cause greater material and energy losses. Therefore, in order to achieve deviation correction and precise control of produ...
