Description
Art
The present invention relates to a kind of coining cement tile molding machine hydraulic system, suitable for mechanical field.
Background technology
The moulding process of cement tile is divided into roll-forming and the major class of compression molding two.Roll-forming utilizes upper and lower folder rod
Extruding so that concrete is molded according to the shape in folder rod section, is then formed according to required length cutting.Compression molding is
After quantitative concrete is added into mould, it is molded under stress.Because the cement tile of compression molding has, tissue is closely knit, water absorption rate
The features such as low (the simply half of roll-forming watt), any surface finish, progressively substitute roll-forming watt, and be promoted.
The content of the invention
The present invention proposes a kind of coining cement tile molding machine hydraulic system, and compacting, the demoulding, lifting, movable workbench are equal
Hydraulic driving mode is employed, is completed manually by PLC control softwares and full-automatic two kinds of functions, manual approach is often used for carrying out
Technological parameter is groped, and full-automatic scheme is used for a large amount of continuous productions, and this mode greatly facilitates operator and hand improves
Production efficiency.
The technical solution adopted in the present invention is.
The control system employs hydraulic drive and is combined with Pneumatic Transmission.Quantitative mechanism, bracket lifting mechanism, product
Unloading device etc. uses Pneumatic Transmission, is swift in motion reliable.
The control system is controlled using PLC.Instruction control hydraulic system and pneumatic system acting are sent by PLC, it is controlled
Processing procedure sequence is adjustable.Realize mechanical, electrical, liquid, gas integral control.
Entirely can to automatically control also single action manual for action for the control system, and operation is flexible, easy to adjust.
The control system makes system architecture compact using Sandwich plate valve, and circuit pressure loss is small, system job stability and
Reliability is high.
Medium pressure system, not only reduce leakage but also ensure that flow system flow is less big.
The control system efficiency high, except the system in high pressure conditions, remaining time is made in system river in the product press time
It is operated in low-pressure state or in unloading condition.
The slide unit of the control system is using slider-crank mechanism buffering good positioning effect.
The beneficial effects of the invention are as follows：The system has good dynamic quality and steady-state behaviour, and its indices reaches
It is expected that requiring, stable and reliable operation, good economic benefits and social benefit are produced.
Brief description of the drawings
Fig. 1 is the color cement tile die press technology for forming process schematic of the present invention.
Fig. 2 is the Make-up machine of cement tile hydraulic system principle figure of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, cement, sand, flyash, water etc. are sent into quantitative stirring machine, quantitative stirring machine after sufficiently mixing and stirring
Quantitative concrete is sent into die cavity, wet shape cement tile is formed after the pressure injection of upper molding head excludes a part of water, uses supporting plate
After taking out the tile in mould, send drying shed to be dried, be then changed into tile of finished product by lacquering technique.
Enough briquetting pressures, meet the requirement of cement tile compactness；Briquetting pressure is adjustable to adapt to different shape, different chis
Very little cement tile forming requirements；Stripping rate, moving speed of table etc. are adjustable, to meet that molding cycle regulation etc. requires；Work
Platform is buffered in end of travel and positioned, and ensures forming machine work smoothness and compacting product not because of impact injury.Forming machine connects for a long time
Continuous work, system effectiveness will height.
Such as Fig. 2, the pressure oil of pump output reaches each solenoid directional control valve through check valve.Pressure head lifting is controlled by valve 14：4Y is obtained
Electricity, pressure oil enters cylinder 16 through valve 18,17 rodless cavities promote cylinder 16,17 descending, while drive the plunger of cylinder 20 up together, this
When replenishing valve 21 open, give the repairing of cylinder 20, ensure plunger fast downlink, cylinder 16,17 rodless cavity fluid are through valve 15 and the oil return of valve 14
Case.When being molded into product on being exercised under cylinder, the retard motion of cylinder 16,17, rodless cavity pressure rise, open sequence valve 19, now
The pressure oil of pump output enters cylinder 20 and loaded to plunger, and obtaining electric delay time by PLC controls 4Y ensures loading pressing forming time；
3Y obtain it is electric, pressure oil through valve 14 through valve 15 enter cylinder 16,17 rodless cavities promote cylinder 16,17 it is up, while through control oil circuit make to fill
Liquid valve 21 is opened, and the plunger of cylinder 20 realizes lifting under cylinder 16,17 up drives, and the plunger cavity fluid of cylinder 20 is through the oil return box of valve 21, cylinder
16th, 17 rod chamber fluid are through valve 18 and the oil return box of valve 14.Stripping action drives demoulding frame by valve 9 and valve 10,13 master cylinders 11,12
Realized relative to upper mould movement.Cylinder 16 and 17, the mechanical synchronization of cylinder 11 and 12.Movable workbench is realized by slider-crank mechanism, bent
Handle controls oscillating cylinder 24 to be swung in the range of 180 ° by valve 22 and valve 23,25.
Hydraulic pressure pump startup, 8Y obtain electric, system unloaded.Any of 1Y, 2Y, 3Y, 5Y, 6Y must be electric, then 7Y is obtained electric simultaneously, i.e.,
System working pressure is set up by valve 8 when the demoulding, lifting, movable workbench, because being stripped, being lifted, movable workbench when load small, valve
8 set pressures are relatively low, about 2.5Mpa or so.4Y obtains electric, then 7Y, 8Y all dead electricity, i.e. forming process on-load pressure are set up by valve 6
For 10.8 Mpa.1Y, 2Y, 3Y, 4Y, 5Y, 6Y all dead electricity when, 8Y obtains electric, system unloaded.
According to the requirement of cement tile die press technology for forming and result of the test, it is 1000kN to determine product molding pressure.In system
Executive component is more, can increase joint etc. leakage from pressure is too high, system working pressure should not be too high, therefore selecting system adds
Load oil pressure is 12 MPa, thus calculates and determines that diameter of plunger is 320mm (sectional area 804cm2) through rounding.Experimental study
Show with actual use, when compacting specification is 420x330 plain tiles, system loads pressure is adjusted to 10.8 MPa by adjustment overflow valve 6
Product molding quality requirement can be met.Quality of item removes to be had outside the Pass with on-load pressure, also relevant with other factors.
Control valve is chosen by rated pressure 16MPa in loop.In order to adjust the demoulding, lifting, moving speed of table, use
Oil return line throttling speed control circuit.Valve 10 and 13, valve 15 and 19, valve 25 and 27 select three MSW-03-X superposing type one-way throttles
Valve.
