Described go up decide board member by last fixed form, go up heat and coil and constitute; Described lower moving plate member is made of moving platen, following heat dish, and last fixed form is fixed on four root posts, and there is upward hot dish its below, and moving platen is fixed on the folding mould oil cylinder, and there is hot down coiling its top.
The utility model adopts frequency conversion and Control Technique of Microcomputer, has changed the mode of operation of existing hydraulic system, and the overflow that has overcome existing machine is many, energy consumption is high, oil temperature height, move jiggly defective.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model frequency conversion and microcomputer control schematic diagram.
The specific embodiment
As shown in Figure 1, special-purpose press comprise locking nut 1, go up fixed form 2, go up heat dish 3, mold 4, column 5, bed die 6, heat dish 7, moving platen 8, hold-down nut 9, lower bolster 10, folding mould oil cylinder 11, travel switch 12 down.Folding mould oil cylinder cylinder body is fixed on the frame, and moving platen 8 is fixed on the folding mould oil cylinder 11, and folding mould oil cylinder 11 is fixed on the lower bolster 10.Locking nut 1 and hold-down nut 9 will be gone up the top and bottom that fixed form 2 and lower bolster 10 are fixed in column 5 respectively, and travel switch 12 is installed on the lower bolster 10, and mold 4 links to each other with last heat dish 3, and bed die 6 coils 7 with heat down and links to each other.Mold 4, bed die 6 are the user and dispose according to actual production.
As shown in Figure 2, the utility model comprises frequency-variable controller 16, motor 17, constant displacement pump 18, microcomputer 15, proportional pressure valve 14, solenoid directional control valve 13.Between power frequency supply and motor 17, be connected with frequency-variable controller 16, motor 17 output shafts link to each other with constant displacement pump 18, the oil-out of constant displacement pump 18 communicates with the oil-in of proportional pressure valve 14, solenoid directional control valve 13, and the oil return opening of solenoid directional control valve 13 and folding mould oil cylinder 11 join.Microcomputer 15 is connected with frequency-variable controller 16, proportional pressure valve 14.
When this machine uses, earlier mold 4, bed die 6 are installed in respectively on heat dish 3 and the following heat dish 7.Machine startup, solenoid directional control valve 13 action transfers matched moulds at a slow speed to when making folding mould oil cylinder 11 quick matched moulds to desired location, enters packing state after mold 4 and bed die 6 are compressed.Sizing material is full of die cavity and carries out chemical reaction under high-temperature high-pressure state, pressurize time-delay after the exhaust.Solenoid directional control valve 13 actions make the 11 quick die sinkings of folding mould oil cylinder after a period of time, solenoid directional control valve 13 actions during crush stroke switch 12, and machine transfers die sinking at a slow speed to, stops up to die sinking.So far machine has been finished a complete working cycles.
The operation principle (see figure 2) of above-mentioned action is: connect power supply, start the machine, the operation microcomputor program makes machine enter locked mode program and die sinking program successively, and promptly folding mould oil cylinder 11 moves back and forth once.Motor 17 drives constant displacement pump 18 fuel feeding, make machine enter each technological action process successively, its pressure of proportional pressure valve 14 timely adjustments under microcomputer 15 controls simultaneously, frequency-variable controller 16 is gathered and be sent to the variation meeting of pressure in the mode of the signal of telecommunication in this process; Frequency-variable controller 16 can carry out calculation process in conjunction with gathering the corresponding technological action signal of telecommunication that comes by microcomputer 15 places with pressure signal, and result is controlled the running of motor 17 in the mode of frequency variation signal.Motor 17 drives constant displacement pump 18 fuel feeding to the rotating speed that the frequency variation signal of input is converted into variation again, and rotating speed the flow of constant displacement pump 18 outputs simultaneously also can be different; Promptly in certain technological action, pressure signal and this technological action signal of being set by microcomputor program can carry out calculation process in frequency-variable controller 16, result is controlled the running of motor 17 in the mode of frequency variation signal, this frequency inputs to motor 17 and makes its output corresponding rotating speeds, and constant displacement pump 18 also can be exported corresponding flow.The flow of system's output also can respective change when this process had realized that technological action changes, and to be reflected on the motor 17 be exactly the variation of power.
