The following describes the course of action of the electric control structure of hydraulic press automatic mould changing device of the present invention.
The 1st step. on touch-screen 22, set needed mould number, number send mould among the automatic mould changing device PLC21 CPU by Ethernet; Satisfy automatic die change condition: fastening screw 26 is in lowering position, and hook 10 is in to return and stops and lowering position, selects manually, automatic selector switch 25 is in automatic mode.
The 2nd step. start automatic die change button 24, mould detection head 12 descends, and floating guide rail 5 jack-up are so that mould moves.
The 3rd step. the hook 11 of variable-frequency motor 9 controls that driven by frequency converter 15 lifts and advances, halt after advancing to the A position mould 3 that just in time can catch in the hydraulic press 2, hook 11 together retreats together with A position mould 3, up to A position mould 3 is hauled out press 2 fully, hook 11 falls unhook, get back to the home position, stop to retreat.
The 4th step. the latch 26 that mould changing device is used to locate lifts, and is started working by the variable-frequency motor 6 that frequency converter 15 drives, and mould changing device integral body is moved to left, and makes the B position mould 4 that needs to change aim at hydraulic presses 2 and stop to move, and latch 26 falls the location.
The 5th step. motor 9 starts promotion hook 11 once more and B position mould 4 together advances, and up to B position mould 4 is sent into hydraulic press fully, halts.
The 6th step. floating guide rail 5 falls, mould detection head 12 rises, 11,12 couples of timing (3-5mm of two detection heads when the mould identifier, exceed this range detection less than signal), the receiving terminal 23 of mould identifier just can receive the signal that transmitting terminal 14 is sent, and send PLC21 to, CPU among the PLC21 is by inner process analysis, the mould that can identify into number, the mould that this mould number and the 1st step touch-screen 22 are set number compares, if unanimity then carry out hook 11 and break off relations and retreat is returned the home position, finish automatic die change.The comparative result difference, hook 11 is hauled out press 2 again with mould, and on touch-screen 22 prompting mould model with set unmatched warning message.
On mould changing device, there are two mould checkout gears promptly to be used to judge that near switch 7,8 the detection mould of replacing is A position or B position; mould is put on the mould changing device and shows that near the switch sender this station has mould; one on two moulds are in press during normal die change; one on mould changing device, by detect have on that station mould just can judge the 4th the step mould changing device be to move to left or move to right.
Fig. 5 is Frequency Converter Control Principle of Electric Engine figure of the present invention, because two motors are not to move simultaneously, so used a frequency converter, motor 6 runnings when KM1 adhesive simultaneously, and motor 9 runnings during the KM2 adhesive.Can change the velocity of rotation of motor 6 and motor 9 by the frequency of regulating frequency converter 15, just change the speed of hook 10 forward-reverse speed and mould changing device move left and right.
In the present invention: PLC and touch-screen are the products of selecting Omron Corp for use; Frequency converter and variable-frequency motor are the products of selecting Mitsubishi for use; The mould identifier is a product of selecting Ba Lufu company for use.
