Description
Technical field:
The utility model relates to the dead slow speed die-sinking device of SMC special hydraulic press, and particularly the crack mould of large-tonnage SMC special hydraulic press is used.
Background technology:
The SMC special hydraulic press is that the industries such as integral die moulding for thermosetting (fiberglass) plastic products, thermoplastic articles manufacture and design.The mode that generally adopts in the application of the crack mould of SMC special hydraulic press at present is the integrated morphology that master cylinder is used for dead slow speed die sinking and quick return, and there is the defective of following common recognition in this mode:
1. the characteristic of SMC special hydraulic press is that mould opening force is very large, particularly the mould opening force of large-tonnage SMC special hydraulic press has reached more than 500 tons, the such place that is connected with slide block of master cylinder many high-intensity screws of needs just, could satisfy the die sinking needs, but can't guarantee also that so screw that long high strength operation brings the danger such as breaks.
2. because for mould opening force is very large, it is very large that the quick return of equipment just can not design, because opening speed is directly proportional with mould opening force, so also just reduced operating efficiency.
3. if very large opening speed design, just needing to increase the special-purpose oil pump of a large amount of backhauls provide enough flows, could realize.According to having become plant capacity excessive, increase the drawback of production cost so again.
Above defective has caused the unnecessary wasting of resources, can't more reasonably increase work efficiency, and there is hidden danger in operator's personal safety.
The utility model content:
The utility model is exactly the problem that exists in the above-mentioned technology in order to solve, and it is fast die-sinking device that a kind of SMC special hydraulic press is provided, and, enhances productivity protection operator's personal safety to reduce the wasting of resources.
The technical solution of the utility model:
SMC special hydraulic press dead slow speed die-sinking device, it is characterized in that, include crack mould oil cylinder, upper cushion block, lower cushion block, mounting base, hydraulic system, main stroke limit, described two crack mould oil cylinders are installed on two mounting bases by screw respectively, two mounting bases are fixed by screws in respectively between the column of the left and right sides, plane on the hydraulic press sill, two upper cushion blocks are screwed in the slider of hydraulic press lower plane left and right sides, two lower cushion blocks use respectively screw fastening two crack mould oil cylinder upper ends, crack mould oil cylinder and hydraulic system and electronic oil pump are connected to form a crack modular system by steel pipe, hydraulic system is installed on the fuel tank of hydraulic press, the oil pocket of two crack mould oil cylinders communicates, keep pressure consistent, be connected with a Pressure gauge between the oil pocket of two crack mould oil cylinders, described main stroke limit includes linear displacement transducer, sensor block, linear displacement transducer is fixed on the left side of hydraulic press, and sensor block is fixed on the slide block left side.The pressure of crack mould oil cylinder and stroke detect by Pressure gauge and main stroke limit, and the stroke limit of described main stroke limit and hydraulic press is same, need not to add in addition stroke limit.
Described crack mould oil cylinder is plunger cylinder, includes plunger rod, cylinder body, guide pin bushing, sealing ring, and step is left in the end of plunger rod, prevents crack mould oil cylinder excess of stroke cause danger.
The upper surface of upper and lower cushion block increases case hardness through Quenching Treatment.
Hydraulic system is installed on the fuel tank of hydraulic press, links on the crack mould oil cylinder by seamless high pressure resistant steel pipe.The crack mould speed of SMC special hydraulic press is generally all smaller, and generally at 0.5-5mm/s, the flow of required pump was very little when crack mould cylinder rose.Crack mould oil cylinder dead slow speed rises and heads on the passive rising of slide block.When the passive rising of slide block, the master cylinder epicoele back pressure of hydraulic press is drained the oil, and creeps during anti-limited slip block dead slow speed backhaul, and hydraulic press master cylinder cavity of resorption arranges the repairing check valve, prevents master cylinder cavity of resorption suction vacuum.After the upper and lower mould of equipment separates a segment distance, be with fast the movable slider backhaul by master cylinder again, overcome withdrawing pattern power.At this moment the plunger rod of slight die sinking oil cylinder is parked in the upper limit of little opening stroke, because crack mould oil cylinder has sutaining valve.When slide block down, it is descending that slide block overcomes the support force of crack mould oil cylinder, and at this moment crack mould oil cylinder is the passive lower limit of getting back to little opening stroke under the effect of slide block.So just can save the time that crack mould cylinder rises, increase work efficiency.The oil pocket of two crack mould oil cylinders is identical, keeps pressure one to make peace and upward presses simultaneously, has so just finished a working cycles.
The utility model has the advantages that:
Crack mould oil cylinder has been arranged, and the backhaul power of the master cylinder of hydraulic press is just not too big, and the weight that only need to satisfy slide block and mould gets final product, and has solved the safety problem that master cylinder is connected with slide block, has effectively guaranteed operator's safety problem.
The backhaul power of master cylinder reduces greatly, and slide block just can quick return after the dead slow speed die sinking, has improved operating efficiency.
The backhaul power of master cylinder greatly reduces, and has saved a part and has aimed at the oil pump that backhaul is used, and has reduced the general power of equipment, has reduced energy consumption, has also reduced production cost to the user.
The utility model not only structural design is compact, and motion is steadily increased work efficiency, and reduces energy consumption, reduces production costs, and is convenient to detachable maintaining, improves the security of equipment.
