Abstract
A kind of hydraulic control system of moulding press is the utility model is related to, belongs to shoe making apparatus field.Including gear oil pump, overflow valve, magnetic valve, check valve, accumulator, pressure switch and molding unit, the magnetic valve, overflow valve, check valve are sequentially connected, check valve is connected to molding unit, gear oil pump is connected between overflow valve and check valve, and accumulator and pressure switch are connected between check valve and molding unit;The utility model solves the problems, such as that hydraulic pressure is ground one's teeth in sleep unit insufficient pressure and unstable, meets the needs of production.
Description
Technical field
It the utility model is related to shoe making apparatus field, more particularly to a kind of hydraulic control system of moulding press.
Background technology
At present, domestic molding leather shoes are more is produced using hydrodynamic mo(u)lding press.The pressure of hydraulic system keep enough and
It is stable, it is to ensure that the big bottom of cemented shoe bonds one of essential condition firm, that decorative pattern is full.But because moulding press is multiple computer desk
Centralized oil supply equipment(A general oil pump can drive 20 to 30 machine operations), operation machine time is short, vulcanization of rubber pressurize
Time is grown, and belongs to intermittent work.Again because molding unit is more people's operations, so the number of units of start simultaneously in the unit interval
It is difficult to determine, also just not accurate enough or flow is excessive for the selection of oil pump output oil amount.
Utility model content
The problem of for shortcomings and deficiencies in the prior art, the utility model proposes a kind of hydraulic control system of moulding press
System, solve the problems, such as that hydraulic pressure is ground one's teeth in sleep unit insufficient pressure and unstable, meets the needs of production.
Technical scheme is used by the utility model solves its technical problem:
A kind of hydraulic control system of moulding press, including gear oil pump, overflow valve, magnetic valve, check valve, accumulator, pressure
Power relay and molding unit, the magnetic valve, overflow valve, check valve are sequentially connected, and check valve is connected to molding unit, gear
Oil pump is connected between overflow valve and check valve, and accumulator and pressure switch are connected between check valve and molding unit.
Further, the gear oil pump, overflow valve and magnetic valve are connected to fuel tank.
Further, it is also associated with oil pressure gauge between the overflow valve and check valve.
Further, it is connected with oil pressure gauge between the accumulator and molding unit.
Further, the magnetic valve uses two-position two-way electromagnetic directional valve.
Further, the accumulator uses bag type accumulator.
The utility model has the advantages that:When oil pump output oil amount be more than molding unit oil mass when, oil pump incited somebody to action
Surplus fluid input accumulator, carries out pressure accumulation;Pressure switch plays a part of to control two-position two-way electromagnetic directional valve, makes overflow valve
Guide's drain tap open or close, realize oil pump whether the purpose of off-load;The effect of check valve is when oil pump is in off-load shape
During state, prevent the pressure oil of hydraulic system from flowing back and reducing pressure.
Brief description of the drawings
Fig. 1 is the utility model total system schematic diagram.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
As illustrated, a kind of hydraulic control system of moulding press, a kind of hydraulic control system of moulding press, including gear oil
Pump 1, overflow valve 2, magnetic valve 3, check valve 4, accumulator 5, pressure switch 6 and molding unit 7, the magnetic valve 3, overflow valve
2nd, check valve 4 is sequentially connected, and check valve 4 is connected to molding unit 7, and gear oil pump 1 is connected between overflow valve 2 and check valve 4,
Accumulator 5 and pressure switch 6 are connected between check valve 4 and molding unit 7.
The gear oil pump, overflow valve and magnetic valve are connected to fuel tank, in overflow valve and check valve, accumulator and mould
Oil pressure gauge is connected between press group.
The magnetic valve uses two-position two-way electromagnetic directional valve, and accumulator uses bag type accumulator.
Specifically, when molding unit workbench is less or all static, and is in vulcanization of rubber packing state, that is,
Say that oil pump output oil amount is more than unit oil mass, oil pump just by the fluid input accumulator of surplus, makes its pressure accumulation.Work as hydraulic system
When pressure reaches maximum working pressure, pressure switch manipulates magnetic valve excitation commutation, connects guide's drain tap of overflow valve
Fuel tank, reach the purpose of oil pump off-load, it is single in off-load so as to reduce the consumption of the rise of oil temperature in hydraulic system and power
It can prevent the pressure oil of hydraulic system from flowing back to valve and pressure is reduced rapidly.
When the work for being molded unit machine makes pressure be down to minimum operating pressure, pressure switch controls magnetic valve again
Dead electricity, guide's drain tap of closing outflow valve, oil pump is set to stop off-load, so as to be pressurized to hydraulic system.When molding unit simultaneously
Start number of units reaches five, when oil cylinder needs a large amount of fluid, and oil pump and accumulator confess pressure oil simultaneously, so as to avoid molding
Unit operation speed is slow, the phenomenon of insufficient pressure occurs, and the pressure of hydraulic system is remained in suitable scope.
