Abstract
The utility model discloses a manual adjustment pressure jump preventing constant-speed control hydraulic system which comprises an oil cylinder and further comprises a function control integration valve block, a hydraulic power source and a reversing valve. The hydraulic power source is communicated with the reversing valve through the function control integration valve block, the reversing valve is communicated with an oil inlet and outlet of the oil cylinder through the function control integration valve block, a double hydraulic control one-way valve is connected inside the function control integration valve block between the reversing valve and the oil inlet and outlet of the oil cylinder, a one-way throttle valve is connected inside the function control integration valve block between the double hydraulic control one-way valve and the oil cylinder, and a speed adjusting valve located in the function control integration valve block is connected outside the function control integration valve block between the double hydraulic control one-way valve and the oil cylinder. The manual adjustment pressure jump preventing constant-speed control hydraulic system is simple in structure and low in cost, works stably, improves safety performance of a disk saw cutting machine tool, prolongs the service life and eliminates the influence of jumping on the cut section roughness.
Description
Technical field
The utility model has related to a kind of hydraulic system, and particularly the anti-pressure kick constant speed of a kind of manual tune is controlled hydraulic system.
Background technique
In saw cutter of disk bed, in order to guarantee the roughness of safety, product working life and cutting section, a main frame saw head cutting section bar feed speed requires steadily without beating, and feed speed possesses function that can fine adjustment; In conventional manual speed regulator solution pressing system, all adopt throttle grverning, but that throttle grverning can be because of the influence of fluctuations speed of system pressure is stable, causes shorten the working life of saw disc, the problem that cutting cross section degree of roughness increases occurs.Adoption rate control system can address the above problem, and can realize full-automation, but cost is expensive.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, cost is low, the Safety performance of working stability, raising saw cutter of disk bed, increase the service life, eliminate the anti-pressure kick constant speed of manual tune of beating on the impact of cutting section roughness and control hydraulic system, overcomes the deficiencies in the prior art.
The anti-pressure kick constant speed of manual tune of the present utility model is controlled hydraulic system, comprises oil cylinder, also comprises that function control set becomes valve piece, hydraulic power supply, selector valve, and hydraulic power supply becomes valve piece to be communicated with selector valve by function control set; Selector valve becomes valve piece to be connected with the oil inlet and outlet of described oil cylinder by function control set, is positioned at function control set and becomes valve piece to be connected with dual hydraulic control one-way valve between selector valve and the oil inlet and outlet of oil cylinder; Between dual hydraulic control one-way valve and oil cylinder, be positioned at function control set and become valve piece to be connected with one-way throttle valve, between dual hydraulic control one-way valve and oil cylinder, be positioned at function control set and become valve piece to be externally connected with the series flow control valve that is positioned at speed-regulating integration valve piece.
Described selector valve is 3-position 4-way solenoid directional control valve; In function control set, become on valve piece to be provided with the oil inlet and outlet of oil cylinder and to be communicated with excess pressure Check point.
The anti-pressure kick constant speed of manual tune of the present utility model is controlled hydraulic system, for the cylinder action of sawing feeding, by solenoid directional control valve, is controlled, and solenoid directional control valve is connected with electrical system and can realizes semi-automatic operation and button is manually controlled; Dual hydraulic control one-way valve start/stop machine pressurize lock function; One-way throttle valve and series flow control valve act on respectively on the inlet and outlet of fuel channel of oil cylinder, adopt oil return mode of speed regulation, and valve body band regulates screw mandrel or handle can realize manual speed and regulates; Selector valve, dual hydraulic control one-way valve, one-way throttle valve are installed on integrated valve block, and series flow control valve is assemblied on integrated valve block separately.Simple in structure, cost is low, working stability, improve saw cutter of disk bed Safety performance, increase the service life, eliminate to beat cutting section roughness is affected.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is structural representation when oil cylinder piston moves to left in the utility model embodiment;
Fig. 3 is structural representation when oil cylinder piston moves to right in the utility model embodiment.
Embodiment
As shown in Figure 1: the 1st, feed cylinder in saw cutter of disk bed, 6 for function control set becomes valve piece, and 9 is that hydraulic power supply 9,2 is selector valve.Hydraulic power supply 9 becomes valve piece 6 to be communicated with selector valve 2 by function control set.Selector valve 2 becomes valve piece 6 to be connected with the oil inlet and outlet of oil cylinder 1 by function control set.Between selector valve 2 and the oil inlet and outlet of oil cylinder 1, being positioned at function control set becomes valve piece 6 to be connected with dual hydraulic control one-way valve 3.Between dual hydraulic control one-way valve 3 and oil cylinder 1, being positioned at function control set becomes valve piece 6 to be connected with one-way throttle valve 4; Between dual hydraulic control one-way valve 3 and oil cylinder 1, be positioned at the series flow control valve 5 that function control set becomes valve piece 6 to be externally connected with to be positioned at speed-regulating integration valve piece 7.Selector valve 2 is the 3-position 4-way solenoid directional control valve joining with electric controller; In function control set, become on valve piece 6 to be provided with the oil inlet and outlet of oil cylinder 1 and to be communicated with excess pressure Check point 8, for the oil inlet and outlet pressure to oil cylinder 1, detect.
As shown in Figure 2: when the piston of oil cylinder 1 need to move to left, selector valve 2 is in right position, and the oil return of oil cylinder 1 is carried out oil return speed governing by series flow control valve 5.
As shown in Figure 3: when the piston of oil cylinder 1 need to move to right, selector valve 2 is in left position, and the oil return of oil cylinder 1 is carried out oil return speed governing by one-way throttle valve 4.
This hydraulic system structure is simple, and cost is low, working stability, improve saw cutter of disk bed Safety performance, increase the service life, eliminate to beat cutting section roughness is affected.
