The high-speed hydraulic machine dynamic stepping control system is characterized in that the oil pump controls pressure oil to respectively enter into upper cavities of the oil cylinders in the main system through two hydraulic oil circuits, a discharge port of one oil circuit is communicated to the upper cavity of a middle oil cylinder through a pipeline, a discharge port of the other oil circuit is simultaneously communicated to the upper cavities of two side oil cylinders through pipelines, the flow direction of high-pressure oil and starting of a cartridge valve are controlled in the two hydraulic oil circuits through electromagnetic directional valves, the upper cavities of the oil cylinders are further respectively communicated to a charging oil tank through pipelines, and prefill valves are respectively arranged in the pipelines. The high-speed hydraulic machine dynamic stepping control system is mainly designed for hydraulic machines needed in high-strength steel plate production, oil inlet of the oil pump is controlled in a stepping mode, the fact that the speed is not reduced is guaranteed, and meanwhile installed power just needs one third of original design power.
Description
Technical field
The utility model relates to the hydraulic control field, relates in particular to a kind of high-speed hydraulic press dynamic classification control system of producing in the required hot forming hydraulic press of high-strength steel sheet that is applied in.
Background technology
At present still take the thickness of steel plate as major parameter, vehicle weight is heavier for domestic automobile industry armor plate strength, and energy consumption is large, not environmental protection.So production intensity is high, thin thickness, lightweight high Strength Steel for Motor Vehicles becomes the product that domestic each auto vendor is badly in need of.
This type of hot-forming high speed hydraulic press requirement work pressing speed is exceedingly fast, and the speed General Requirements and operates steadily about 60 ~ 250mm/s, without the pause creeping phenomenon.If according to normal hydraulic press design, the hydraulic press installed power can be very large, the use cost in user's later stage is very high.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of high-speed hydraulic press dynamic classification control system is provided, the main required hydraulic press of production high-strength steel sheet of giving need design, and when assurance speed did not reduce, installed power only needed 1/3rd of former design power.
The utility model is achieved through the following technical solutions:
A kind of high-speed hydraulic press dynamic classification control system, include oil pump, three oil cylinders in the main system, it is characterized in that: described oil pump does not enter into the main system cylinder upper cavity oil by two-way hydraulic circuit controlled pressure oil content, and the discharging opening of one of them oil circuit is by the epicoele of pipeline communication to middle oil cylinder, the discharging opening of another oil circuit is communicated to the epicoele of two side cylinders simultaneously by pipeline, in the described two-way hydraulic circuit respectively by solenoid directional control valve control high-pressure oil flow to the startup of inserted valve, the epicoele of described oil cylinder also arrives surge-tank by pipeline communication respectively, and is respectively equipped with prefill valve in the pipeline.
Be connected with connecting pipe between the described two-way hydraulic circuit, be provided with in the described connecting pipe and prevent mutually Solenoid ball valve and the check valve of string.
The inserted valve of described two-way hydraulic circuit is respectively two, controls respectively by minute solenoid directional control valve of total solenoid directional control valve and each oil circuit respectively.
Its principle is: grading control is adopted in the oil pump oil-feed, the first order, oil cylinder in the middle of all oil pump feeds are only supplied with by solenoid directional control valve control, the dual-side oil cylinder passes through prefill valve directly from the fuel tank oil suction, the pressure that produces is 1/3rd press power, the second level, all oil pump feeds are supplied with two oil cylinders of side by solenoid directional control valve control, and a middle oil by prefill valve from the fuel tank oil suction, the pressure that produces is 2/3rds press power, the third level, and all oil pump feeds are supplied with three oil cylinders, produce the pressure of full tonnage, 1/3rd when at this moment hydraulic press speed only have the first order; Whole dynamic classification all uses the PLC programme-control, does not adopt original button stepping, controls more steady, convenient.
The utility model has the advantages that:
The utility model need design mainly for the required hydraulic press of production high-strength steel sheet, and grading control is adopted in the oil pump oil-feed, and when assurance speed did not reduce, installed power only needed 1/3rd of former design power.
