Abstract
The invention discloses a control method of the automatic linkage between a hydraulic forging press and an operation machine. The control method comprises the following steps: firstly, the mutual communication relation between a controller of the hydraulic forging press and a controller of the operation machine is built; secondly, self inspections are respectively carried out on the controller of the hydraulic forging press and the controller of the operation machine; thirdly, when the two diagnosis results in the second step are both normal, the controller of the hydraulic forging press sends out an action command to the operation machine, and the operation machine conducts machining on a machined piece according to the received action command; fourthly, after the operation machine completes the action command, the controller of the operation machine utilizes a sensor for collecting the size parameter information of the machined piece and sends the size parameter information of the machined piece to the controller of the hydraulic forging press, and the controller of the hydraulic forging press conducts analysis on the received size parameter information and conducts adjustment on actions of the operation machine according to the analysis result. The control method has the advantages of being high in machining precision, high in automation degree, low in failure rate and easy to operate.
Description
Technical field
The present invention relates to the hydraulic forging press technical field, particularly relate to the control method of automatic linkage between a kind of hydraulic forging press and the manipulator.
Background technology
Develop rapidly along with the hydraulic forging press technology, the automatization level of hydraulic forging press improves constantly, in recent years, along with people's improving constantly the hydraulic forging press request for utilization, traditional interlock mode multidigit manual operation, be that press operation worker and manipulator operative employee work in coordination to link, the function that does not have robotization control, find through long-term practice, there is following defective in these traditional interlock methods: one, control accuracy is low, can't satisfy the forging process of precise part; Two, when forging process needs constantly to switch between a plurality of positions, operating process more complicated, and the operation steps that often can make a mistake, thus cause rejection rate constantly to rise.Therefore, design a kind of control accuracy high, the control method of hydraulic forging press simple to operate and manipulator automatic linkage seems particularly important.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of and be convenient to that machining precision is high, automaticity is high, the control method of automatic linkage between failure rate is low, hydraulic forging press simple to operate and the manipulator.
The technical scheme that the present invention takes for the technical matters that exists in the solution known technology is:
The control method of automatic linkage comprises the steps: between a kind of hydraulic forging press and the manipulator
The controller of step 1, hydraulic forging press is set up online request to the controller transmission of manipulator, and the controller of described manipulator is set up mutual correspondence with the controller of described hydraulic forging press after receiving above-mentioned online request;
The controller of step 2, described hydraulic forging press is diagnosed the controller that the duty parameter of hydraulic forging press sends to manipulator, and the controller of described manipulator is diagnosed the controller that the duty parameter of manipulator sends to hydraulic forging press;
Step 3, when two diagnostic results in the step 2 are when normal, the controller of hydraulic forging press is to the instruction of manipulator sending action, manipulator is processed workpiece according to the action command that receives;
Step 4, after manipulator is finished above-mentioned action command, the controller of manipulator utilizes sensor to gather the dimensional parameters information of workpiece, and described dimensional parameters information is sent to the controller of hydraulic forging press, the controller of hydraulic forging press is analyzed the above-mentioned dimensional parameters information that receives, and by analysis result the action of manipulator is adjusted.
As preferred version, the present invention has also adopted following technical scheme:
Connect by the Profibus bus between the controller of described hydraulic forging press and the controller of manipulator.
On the controller of the controller of hydraulic forging press and manipulator, also be connected with the DP/DP coupling mechanism.
The duty parameter of described hydraulic forging press comprises: emergent stopping position, slide block stop position, the clamp anglec of rotation, slider displacement and operating position.
The duty parameter of described manipulator comprises: slide block limit point, sensor states, have or not broken string, have or not short trouble, each bus node fault diagnosis, electric-control system have or not fault alarm and hydraulic system to have or not fault alarm.
Advantage and good effect that the present invention has are: the present invention has realized the interlock between hydraulic forging press and the manipulator by establishing a communications link between hydraulic forging press and manipulator, so improved well the machining precision of system; Because all working step among the present invention is finished automatically by the controller of hydraulic forging press and the controller of manipulator, so have higher work efficiency than traditional human-computer interaction; Simultaneously, the control procedure of robotization can reduce the defect rate of workpiece well than existing human-computer interaction process.
