Description of drawings:
Fig. 1 is the roller schematic diagram that unloads of the present utility model;
Fig. 2 is a dress roller schematic diagram of the present utility model;
Accompanying drawing 3 is the hydraulic system schematic diagram of roll change buggy;
Accompanying drawing 4 is electric control theory figure of the present utility model.
The specific embodiment:
Embodiment of the present utility model: it comprises the branch platens 2 such as 4 that cylinder body 1 and 25mm are thick, cylinder body 1 is connected on the removable roll change buggy, plunger 3 is housed in hydraulic cylinder 1, and plunger 3 is connected with control device 8 able to programme, and control device 8 able to programme adopts SIEMENS LOGO! 230RC control device able to programme, platen 2 is connected on the tapered sleeve 5 by connecting bolt 4, is connected with bolt 6 on tapered sleeve 5 and platen 2.
When unloading roller, as shown in Figure 1, front end with tapered sleeve 5 is inserted in the axis hole of roll 7 earlier, with 3 bolts 6 pass that platen 2 is screwed in that axle is gone up and and platen 2 between reserve the gap of 8mm, then cylinder body 1 is enclosed within and rotates a direction and platen 2 joints on the platen 2, start the hydraulic pump of removable roll change buggy then, the plunger 3 of cylinder body 1 is withstood on the women's head-ornaments of 3 bolts 6, after suppressing the pressure of setting, can take out roll, unclamp 3 bolts 6 then, take out cylinder body 1 and tapered sleeve 5, the whole roller that unloads is finished.
When the dress roller, as shown in Figure 2, the front end with tapered sleeve 5 is inserted in the axis hole of roll 7 earlier, then cylinder body 1 is placed on the tail end of tapered sleeve 5, and cylinder body 1 and tapered sleeve 5 are tightened with 3 bolts 6, start the hydraulic pump of removable roll change buggy then, suppress the pressure of setting after, the plunger 3 of cylinder body 1 ejects release on platen 2, roll 7 can be loaded onto, unclamp 3 bolts 6 then, take out cylinder body 1 and tapered sleeve 5, whole dress roller is finished.
Hydraulic system of the present utility model as shown in Figure 3, each label corresponding equipment is respectively among the figure: 001-oil pump, 002-solenoid directional control valve, 003-solenoid directional control valve, 004-solenoid directional control valve, 005-pressure regulator valve, 006-pressure regulator valve, 007-filter, 008-snap joint, 009-Pressure gauge, 010-bi-bit bi-pass reversal valve.
Whole electric control system of the present utility model is divided into major loop and control loop, major loop major control hydraulic pump motor, control loop has control device 8 able to programme and instruction software thereof, the collection of signal input and output, operation and state demonstration etc., its circuit be as shown in Figure 4:
The roll process control is installed: change-over switch S2 chooses switch bit, indicator lamp G2 is installed to be lighted, press start button Sm, import control device I1 able to programme, through logical operation control, compile program controller Q2 output, magnetic valve SV1 coil gets electric work, cylinder plunger work pressurization, pressure switch PS1 closure when pressure is raised to 140bar is imported control device I3 able to programme through logical operation control, control device Q3 output able to programme, magnetic valve SV2 coil gets electric work, and cylinder plunger work pressurization reaches 400bar up to pressure.Release button Sm, magnetic valve SV2 coil dead electricity immediately quits work, the cylinder plunger release, magnetic valve SV1 coil through control device delay adjustments able to programme after 5 seconds dead electricity quit work, the cylinder plunger release, working head retraction resets installation.
