A machine table of the circular disc stone sawing machine is provided with a circular disc saw motor and a cutter dropping motor; the circular disc saw motor is connected with the microprocessor connected with a trolley motor; a trolley and the trolley motor are arranged under the circular disc saw which is driven to rotate by the circular disc saw motor and the cutter dropping motor and integrally moves up and down. The microprocessor receives a current signal produced by the circular disc saw motor and compares the current signal with a manual signal to produce a control signal, and a frequency conversion speed regulator of the trolley motor is driven to make the trolley motor run. The utility model can make the circular disc stone sawing machine to be suitable for different stones, the cutting quality is ensured, and the cutting for a multiple-sheet body and a thin-sheet body is realized.
Description
The utility model belongs to the novel electric control system of circular saw cutting stone material machinery.
At present, the electrical system operation principle of circular disk type stone sawing machinery is: at first under manual state, the circular saw bit vertical direction of main driven by motor is adjusted to apart from the suitable position of rough stone block, the chassis level that will drag rough stone block then is transferred to a certain end (travel switch of this end is depressed), after the original state adjustment is intact, start the automatics that the main motor that drives saw blade is restarted system.Enter auto state; chassis begins to move horizontally with fixed speed; when moving to the other end; after the travel switch of the other end contacts; chassis stops, and is that the timer that configures starts circular saw bit decline motor again, reach the time of original setting when the time after; the decline motor stops; the chassis motor begins the same with last time in the opposite direction speed again and moves, continuous so back and forth, up to the decline motor to the desired location of vertical direction; main motor stops; chassis stops, and the motor that vertically descends counter-rotating promotes circular saw bit; when rising to the upper limit position of vertical direction; the lifting motor is shut down, and it is burst that circular saw bit moves horizontally electric motor starting, after the control timer of burst motor arrives preset time; system starts main motor again automatically; main electric motor starting finishes, and chassis begins again to move, and repeats above action; after the burst motor moved to desired location, the processing of whole waste material was all finished.
In this electrical system, the stroke size (promptly falling the cutter amount) that circular saw bit descends, manually set by the time relay, the speed that chassis moves is all fixed in each stroke, electric control system is for the different cutter amounts of falling like this, different hardness of stone, different diamond segment quality, the total load amount of bearing of the matrix of circular saw bit and main motor is different, therefore, arbitrary dynamic factor excessive (as fall cutter amount big) all can cause cut quality not good, or the damage of diamond cutlery, when fall the cutter amount select too little, direct reduction cutting efficiency.
The purpose of this utility model provides a kind of automated closed-loop rational in infrastructure, that improve cutting efficiency and quality and controls circular disk type stone sawing machine.
The purpose of this utility model is achieved in that a kind of closed loop controls circular disk type stone sawing machine automatically, it comprises the microprocessor of being made up of single-chip microcomputer or integrated circuit 6, circular saw motor 1 is set on the circular disk type stone sawing machine board 7, falls cutter motor 2, circular saw motor 1 is connected with microprocessor 6, microprocessor 6 is connected with chassis motor 5, chassis and chassis motor 5 are positioned at circular saw 3 belows, and circular saw 3 is driven and rotation by circular saw motor 1, and cutter motor 2 drives and integral body moves up and down by falling; Circular saw motor 1 produces current signal, and microprocessor 6 is accepted above-mentioned current signal and compared with artificial input current signal, produces control signal, drives the variable-frequency governor that the chassis motor is used, 5 runnings of variable-frequency governor console vehicle motor.When being, circular saw 3 and stone material contact the cutting beginning during state, microprocessor generation control signal, and the control variable-frequency governor drives the chassis motor and turns round with setting speed.This speed can solve " playing a minor role " cut quality problem of cutting beginning state, and circular saw 3 is a slice or the above saw blade of a slice.
Main feature of the present utility model is:
1, the utility model has been realized closed-loop control.At first to optimum load (i.e. the recommended current of main motor) that circular saw can bear of micro computer input, the operating current of micro computer real-time dynamic monitoring master motor then, when measured value during greater than set-point, signal of micro computer output, the variable-frequency governor of this signal controlling chassis motor slows down the chassis translational speed.When measuring electric current less than given electric current, micro computer provides a signal, and the variable-frequency governor of console vehicle motor is accelerated the chassis translational speed.The utility model can make circular disk type stone sawing machine adapt to the stone material of different hardness, the matrix of different hardness, the diamond segment of different sharpness under the situation of falling the cutter amount greatly.And make cutter under former equal state, carry out the work of optimum efficiency ground.
2, owing to adopted microcomputerized control, native system also has the artificial intelligence cutting function.We find after deliberation, circular saw bit (the especially above circular saw bit of 1600mm) is when cutting rough stone block, the diamond of circular saw bit is rigidly connecting the A face that touches, when B face or C face, be illustrated in fig. 3 shown below, if fall the movement velocity mismate of cutter amount and chassis, the circular saw sector-meeting directly influences cut quality to the direction skew perpendicular to the circular saw face.At this situation, we utilize the artificial intelligence control method, when saw blade rigidly connects and touches at A, B, C, three faces, when cutting does not also form swage set, micro computer meeting automatic control console car variable-frequency governor, the movement velocity of the chassis that slows down is after swage set forms, micro computer then can be accelerated the translational speed of chassis again, has so just guaranteed cut quality and efficient.We are called soft loading cutting method this control method.
3, because the utility model adopts closed-loop control and artificial intelligence loading method can guarantee cutter realization multi-disc (combination saw) and the cutting of thin slice body, the successful Application of intelligence loading method, the load capacity that can guarantee each saw blade to combined saw blade in cutting process is synchronous, be that the load value that bears of each saw blade is approximate impartial, the thorough like this quality when having guaranteed the saw blade cutting.The patterning method that the utility model adopts is applicable to the stone material saw cutter of disk of any structure, and particularly combination saw cutter or monolithic saw is transformed into 2 or 3 cutters, has high application value to improving cut quality and efficient.
