Description
Technical field
The utility model relates to a kind of bogie shaped steel hydraulic straightening machine, particularly a kind of bogie shaped steel hydraulic straightening machine electric control gear.
Background technology
The manufacturing of bogie needs a large amount of shaped steel and welding structural element, and these workpiece are by the compression moulding of different-thickness steel plate.Receive the influence of self stress, external environmental factor and process equipment precision; Shaped steel after the moulding or welding structural element tend to take place distortion in various degree, and deflection is from several millimeters to tens millimeters, and the shape of distortion is also varied; The distortion that has is arch shape, and the distortion that has is distorted shape.Bogie shaped steel hydraulic straightening machine is a kind of special equipment that is used to repair this type of situation.
It is that current collection, liquid, the light of core is the closed-loop control system of one with Programmable Logic Controller (PLC) that bogie shaped steel hydraulic straightening machine is one, this power distribution equipment through the operating desk operation operation can realize head with hand held controller fast down, slowly under, actions such as compacting, backhaul and urgent backhaul.Can carry out scene setting and adjustment to the position that workpiece begins to pressurize according to user's needs through this electric control gear; Parameter such as operating pressure, stroke all can show on touch-screen and set within the specific limits.
Workpiece needs operating personnel according to workpiece state in alignment process, and the adjustment head is to the diverse location point of workpiece, to realize the best alignment of workpiece.Whether when adjustment head position, it is suitable to observe the head impetus often need to apply certain pressure, needs to use hand held controller operation in front of equipment this moment.And under normal circumstances, for safety, checkout gear has man-hour meeting autostop near detecting equipment.Because the current main-stream electric control gear, operating desk control is changed adopt with the hand held controller operation more and is selected knob or touch screen interface selection mode, and this mode is simple, suitable.But to this equipment, the hand held controller operation only is applied to equipment debugging or workpiece adjusting stage, needs operating personnel's consciousness that tightens security especially in this stage.
Summary of the invention
For solving the problems referred to above that prior art exists, the utility model will design a kind of bogie shaped steel hydraulic straightening machine electric control gear that can avoid maloperation to increase security.
To achieve these goals, the technical scheme of the utility model is following:
A kind of bogie shaped steel hydraulic straightening machine electric control gear; Comprise PLC, touch-screen, panel circuit, oil pressure and head displacement transducer, Oil pump electrical machinery control circuit and hand held controller; Described PLC is connected with hand held controller with head displacement transducer, Oil pump electrical machinery control circuit with touch-screen, panel circuit, oil pressure respectively; Described Oil pump electrical machinery control circuit is connected with Oil pump electrical machinery; Oil pump electrical machinery is connected with the 380V AC network through A.C. contactor; Described panel circuit is connected with the operating desk panel, at a distance of certain distance two back springing type buttons is installed on the described operating desk panel, and two back springing type button series connection backs link to each other with the switching value input point of PLC.
The operation principle of the utility model is following:
The operating pressure value of the utility model, head stroke etc. can be set through touch-screen, detect and feed back to PLC in real time through oil pressure and head displacement transducer, thereby realize the automatic control of pressure and stroke.Bogie shaped steel hydraulic straightening machine can be divided into two kinds of duties: the one, normal operating conditions adopts operating desk control this moment, realize to head fast down, slowly down, operations such as compacting, pressurize, backhaul, urgent backhaul; The 2nd, equipment debugging or workpiece adjustment state adopts the control of hand-held device during this period, realize to head fast down, slowly down, operations such as backhaul, urgent backhaul.
If realize that operating desk control is to hand held controller control conversion; At first on touch-screen, click the hand held controller action button; Two back springing type buttons on the push deck plate are simultaneously with the hands connected the PLC switching value input point that is attached thereto then.After control program detected this input point and is switched on, it is electric that an inner soft relay of PLC is got, and realizes self-locking; Simultaneously, cut off another inner soft relay consing control was lost efficacy, realize the hand held controller efficient in operation.Because these two buttons must with the hands be pressed the conversion that could realize hand held controller, so be called " both hands close start button " simultaneously at a distance of certain distance.
Compared with prior art, the utlity model has following beneficial effect:
Whether bogie shaped steel straightener need repeatedly be adjusted the position of head on the shaped steel surface in carrying out shaped steel plane alignment process, be in course of adjustment and need slowly exert pressure, suitable with an observed pressure place value.The operating personnel that are in course of adjustment like this must operate with hand held controller near hydraulic straightening machine, thereby can bring operating personnel's safety problem.For this reason; In order to remind operating personnel when using hand held controller to adjust operation, will take care; The utility model has been installed two back springing type buttons at a distance of certain distance on the operating desk panel, two back springing type button series connection backs are linked to each other with the switching value input point of PLC, because this setting; Operating personnel must with the hands press the conversion that could realize hand held controller simultaneously, have played the safety-conscious effect of prompting operating personnel through adopting this conversion regime.
