Description
Technical field
The present invention relates to a kind of control system of hydraulic drive type Rolling shear rolling cut track, belong to Rolling shear control system technical field.
Background technology
At present, on cut deal finishing line, Rolling shear is a kind of main equipment, existing Rolling shear is mainly based on mechanical type Rolling shear, its primary structure drives eccentric drive shaft to drive cutting edge to realize rolling cut operation by main motor of cutting, its rolling cut track realizes when device fabrication just fixing by the rotation of excentric shaft, in actual production operating mode, the sheet material of different-thickness all adopts same rolling cut track easily to cause the waste of production time, and relevant control device cost is higher, the complicated maintaining for the later stage of control mode makes troubles.
Summary of the invention
For solving the nonadjustable technical matters of rolling cut track that prior art exists, the invention provides a kind of can for the sheet material adjustment rolling cut track of different-thickness, it is convenient to control, the control system of the hydraulic drive type Rolling shear rolling cut track that production cost is low.
For achieving the above object, the technical solution adopted in the present invention is a kind of control system of hydraulic drive type Rolling shear rolling cut track, comprise upper scissor blade and for the hydraulic jack that drives upper scissor blade to move up and down and ram control valve, also comprise PLC control system, analog output module and absolute value signal receiver module, described PLC control system by bus cable respectively with analog output module, absolute value signal receiver module is connected, described analog output module is connected with ram control valve by cable, described absolute value signal receiver module is connected with linear type displacement sensor by cable, described linear type displacement sensor is arranged in hydraulic jack, described PLC control system is connected with human-computer interaction interface by telecommunication cable.
Preferably, described analog output module is connected with ram control valve by double screen twisted signal cable.
Preferably, described absolute value signal receiver module is connected with linear type displacement sensor by scrambler private cable.
Compared with prior art, the present invention has following technique effect: structure of the present invention is simple, it is convenient to control, adopt intelligentized control method, according to the difference of supplied materials thickness and material, the mistiming changing main reference position and successively action of cutting hydraulic cylinder realizes the change of the angle of shear and rolling cut track, thus it is different to realize the shear time needed for the sheet material that sheet material is comparatively large with thickness, intensity is higher that thickness is thin, intensity is low, improve production efficiency, effectively reduce production cost.

Embodiment
In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, a kind of control system of hydraulic drive type Rolling shear rolling cut track, comprise upper scissor blade 12 and for the hydraulic jack 11 that drives upper scissor blade to move up and down and ram control valve 4, also comprise PLC control system 1, analog output module 2 and absolute value signal receiver module 3, PLC control system 1 by bus cable 10 respectively with analog output module 2, absolute value signal receiver module 3 is connected, analog output module 2 and absolute value signal receiver module 3 can be laid according to on-the-spot actual condition is distributed, exchanges data is realized with PLC control system 1, analog output module 2 is connected with ram control valve 4 by double screen twisted signal cable 7, for hydraulic control oil cylinder, absolute value signal receiver module 3 is connected with linear type displacement sensor 5 by scrambler private cable 6, linear type displacement sensor 5 is arranged in hydraulic jack 11, absolute value signal receiver module 3 can gather the overhang of current hydraulic oil cylinder, thus determine the position of upper scissor blade, PLC control system 1 is connected with human-computer interaction interface 8 by telecommunication cable 9.To wait that shearing thickness of slab is input in PLC control system 1, then selects different shearing curves by human-computer interaction interface 8, to shorten shear time, provides shear efficiency by human-computer interaction interface 8.Independent poling when wherein scrambler private cable 6, double screen twisted signal cable 7, telecommunication cable 9 and bus cable 10 lay good earth prevents on-the-spot electromagnetic interference (EMI) on the impact of signal.
As shown in Figure 2, be the connected mode of two hydraulic jacks 11 and upper scissor blade 12, linear type displacement sensor 5 is arranged in two hydraulic jacks 11.Figure can find out that the cutting edge of its respective side when side hydraulic jack stretches out can decline thus, stretches out its respective side cutting edge decline through opposite side hydraulic jack after a period of time.When side hydraulic jack reaches certain position, start to regain, respective side cutting edge starts to rise, and now opposite side hydraulic jack continues to stretch out and makes cutting edge minimum point move to hydraulic jack respective side, hydraulic jack starts withdrawal and completes a rolling cut action subsequently, and concrete movement locus is see Fig. 3.The thickness of sheet material and the difference of material is sheared according to waiting, the mistiming of adjustment main reference position and successively action of cutting hydraulic cylinder changes the angle of shear and rolling cut track, thus it is different to realize the shear time needed for the sheet material that sheet material is comparatively large with thickness, intensity is higher that thickness is thin, intensity is low, effectively improve shear efficiency, reduce production cost.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should wrap within the scope of the present invention.
