Description
Technical field
The present invention relates to the heavy automaton of a kind of centrifugal casting machine pipe, realize the real-time adjustment of spun casting cast tube Guan Chong.
Background technology
In the centrifuge casting cycle; It is one of important indicator of Centrifugal Machine Control level that the pipe of cast tube is heavily controlled, and the gap of the actual Guan Chongyu desired value of cast tube is directly connected to the quality and the production cost of cast tube; Actual pipe is great heavily will to cause production cost high in target tube; Actual Guan Chong might be defective less than the heavy product of target tube, so in the centrifugal casting, pipe heavily control is an important technology.At present, in the centrifugal casting, the control of Guan Chong is that the site operation people turns over the speed packet realization according to the practical experience manual adjustments.Shortcoming: labour intensity is big, and the control effect is relevant with operator's personal experience, and product quality stability can not be guaranteed.
Summary of the invention
In order to overcome the shortcoming of prior art, the present invention provides a kind of centrifugal casting machine pipe heavy automaton, and it can realize the automatic adjusting that cast tubes is heavy according to technological requirement.
The present invention solves the technical scheme that its technical problem takes: it comprises:
Industrial touch-screen: be installed on the operating desk, be connected with PLC in the regulator cubicle through EPA, realize target tube reset fixed, turn over that the bag empirical data is set, the representation of actual pipe is shown and regulate the parameter debugging functions;
Regulator cubicle: PLC is installed in the regulator cubicle; The input interface tube connector remeasurement weighing controller of PLC; The communication interface of PLC is through the touch-screen on the Profibus-DP bus attended operation platform; Reception from the target tube tuple of input according to, regulate corrected parameter and turn over bag experience setting data, bag hydraulic regulation valve is turned in the analog quantity output port of PLC control casting;
Weighing controller and LOAD CELLS: be installed on the centrifugal casting machine, be used for casting and accomplish the back and manage re-detection, and will manage heavy signal and offer described PLC with 4~20mA;
Absolute value incremental-rotating coder: be installed under the fan-shaped bag of casting, be used to detect fan-shaped bag flip angle, and angle signal is offered described PLC with pulse mode;
Wrap the hydraulic regulation valve with turning over: be installed in the hydraulic valve platform of centrifugal casting machine, be connected, be used to control fan-shaped bag upset with the package hydraulic press structure that turns over of fan-shaped bag.
The present invention can realize the automatic adjusting that cast tubes is heavy based on technological requirement, product quality and high efficiency, and labour intensity is low, has reduced production cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Accompanying drawing is a calcspar of the present invention.
The specific embodiment
Shown in accompanying drawing, the present invention includes industrial touch-screen, regulator cubicle, weighing controller and LOAD CELLS, absolute value incremental-rotating coder and turn over bag hydraulic regulation valve.
Described industrial touch-screen is installed on the Field Console; Be connected with PLC (Programmable Logic Controller) in the regulator cubicle through the Profibus-DP fieldbus, target setting Guan Chong, turn over the bag empirical data, regulate correction factor and show actual Guan Chong and each item setting value in real time.
Be equipped with in the described regulator cubicle; The input interface of said PLC connects the heavy signal of actual pipe from on-the-spot weighing controller; The communication interface of PLC connects the industrial on-the-spot touch-screen on the Field Console through the Profibus-DP fieldbus; Acceptance is managed tuple according to touch-screen from the setting data of touch-screen input with transmission reality, receives the position signalling from on-the-spot absolute value incremental-rotating coder through counter module, controls to turn over through the analog output channel and wraps the hydraulic regulation valve.
Described weighing controller and LOAD CELLS are installed in the scene, are used for cast-in-place and accomplish the back and manage re-detection, and will manage heavy signal and offer the PLC system with 4~20mA.
Described absolute value incremental-rotating coder is installed under the fan-shaped bag of cast-in-place, is used to detect fan-shaped bag flip angle, and angle signal is offered the PLC system with pulse mode.
The described bag hydraulic regulation valve that turns over is installed in the hydraulic valve platform, is used to control fan-shaped bag upset.
Described PLC adopts the S7-400 series of Siemens Company.Described touch-screen adopts the MP377 of Siemens Company.
Based on production requirement; Need before using first at the scene on the touch-screen to set and turn over speed packet, target tube and heavily reach correction factor based on experience; After casting is accomplished for the first time; According to after relatively, draw next pipe casting needed turn over speed packet through certain algorithm based on the cast tube pipe tuple certificate of field measurement and target tube tuple, the aperture of when next pipe casting, turning over the bag control valve with the Data Control that calculates realizes turning over the adjusting of speed packet; Thereby make the heavy slight fluctuations up and down of the fixed target tube of product pipe tight encirclement by the enemy winding, and unlikely with because the knowhow deficiency causes the heavy deviation of actual Guan Chongyu target tube too big.Can significantly improve product quality and operating efficiency through the present invention, reduce labour intensity and reduce production cost.
