The following describes the two travelling table structures of T type of hydraulic press of the present invention and the course of action of driving and control system thereof.
The 1st step. hydraulic press 1 is at first mold between the operating period, and promptly first travelling table 4 is in A position, travelling table location 7, the first molds and is installed on first travelling table 4, and main frame runs well, and produces and carries out as usual.This moment, second travelling table 5 was in C position, travelling table location 9, was between lay-up period, and be installed in second mold on second travelling table 5 this moment, do not influence the ordinary production of hydraulic press 1.
The 2nd step. after being used to complete, the first mold production needs to change second mold, make hydraulic press 1 main frame be in home, be that slide block 3 is in the extreme higher position, " host work platform " selector switch 37 that control T type is shifted out on operation panel 2 panels of two travelling tables places " workbench " position, " first workbench, second workbench " selector switch 22 places " first workbench " position, " workbench clamping jacking " selector switch 21 places " jack-up " position, the cylinder 36 that rises and falls that travelling table is four jiaos is in the jack-up position, be separated from until first travelling table 4 and detect the A position and put in place behind the limit switch 13, push " workbench moves to left " button 23, more than all buttons and selector switch and limit switch signal all be connected with input/output module 35 among the controller PLC19 in control T type shifts out the operation panel 2 of two travelling tables, through PLC19 internal processes operating ratio after, condition satisfies permission first travelling table 4 and is moved to the left on T type guide rail 6, controller PLC19 is by A.C. contactor 30 adhesives of the auxiliary reclay 32 controls first travelling table mobile motor 17, start the first travelling table mobile motor 17 simultaneously, detect the B position and put in place till limit switch 14 senders until moving to, this moment, first travelling table 4 stopped on 8 positions, B position, travelling table location, had realized the switching of 7-B position, the first travelling table 4A position 8.
The 3rd step. push " moving behind the workbench " button 26, after the operation of PLC19 internal processes, condition satisfies permission first travelling table 4 and moves backward on T type guide rail 6, controller PLC19 is by A.C. contactor 30 adhesives of the auxiliary reclay 32 controls first travelling table mobile motor, start the first travelling table mobile motor 17 simultaneously, detect the D position and put in place till limit switch 16 senders until moving to, this moment, first travelling table 4 stopped on 10 positions, D position, travelling table location, had realized the switching of 8-D position, the first travelling table 4B position 10.
The 4th step. " first workbench, second workbench 2 " selector switch 22 is placed " workbench 2 " position, push " moving behind the workbench " button 26, after the operation of PLC19 internal processes, condition satisfies permission second travelling table 5 and moves backward on T type guide rail 6, controller PLC19 is by the A.C. contactor adhesive of the auxiliary reclay 32 controls second travelling table mobile motor 18, start the second travelling table mobile motor 18 simultaneously, detect the B position and put in place till limit switch 14 senders until moving to, this moment, second travelling table 5 stopped on 8 positions, B position, travelling table location, had realized the switching of 9-B position, the second travelling table 5C position 8.
The 5th step. push " workbench moves to right " button 24, after the operation of PLC19 internal processes, condition satisfies permission second travelling table 5 and moves right on T type guide rail 6, controller PLC19 is by the A.C. contactor adhesive of the auxiliary reclay 32 controls second travelling table mobile motor 18, start the second travelling table mobile motor 18 simultaneously, detect the A position and put in place till limit switch 13 senders until moving to, this moment, second travelling table 5 stopped on 7 positions, A position, travelling table location, had realized the switching of 8-A position, II travelling table 5B position 7.
The 6th step. " workbench clamping jacking " selector switch 21 that will control on operation panel 2 panels that the T type shifts out pair travelling tables places " clamping " position, the cylinder 36 that rises and falls that travelling table is four jiaos is in lowering position, push down until second travelling table 5 and to detect the A position and put in place behind limit switch 13 senders, again " host work platform " selector switch 37 is placed " main frame " position.After second mold and main frame and workbench connected, just can directly continue to have produced, thereby save the time of waiting in the die change process from workbench loading and unloading mould, improve production efficiency greatly.
And the like, in the second mold part production process, first mold is moved from first travelling table 4, change the 3rd mold, treat that the second mold part production on second travelling table 5 is finished after, repeat the 1-6 step to get final product.
When first travelling table 4 or second travelling table 5 are mobile on T type guide rail 6, controller PLC19 drives frequency converter 28 in conjunction with button on the operation box panel and knob, rotating speed with the drive motors that is used for changing first travelling table 4 and second travelling table 5, thereby realize the change of speed when the first travelling table mobile motor 17 and the second travelling table mobile motor 18 move, in order to guarantee first travelling table 4 and second travelling table, 5 stable action, the location accurately.
