Abstract
The invention discloses an automatic prepressing pressure transmission and reduction device. The automatic prepressing pressure transmission and reduction device comprises a hydraulic oil tank and an air pressure tank. A hydraulic valve is arranged between the hydraulic oil tank and the air pressure tank, the outlet of the hydraulic oil tank is connected with a hydraulic hose, oil inside the hydraulic oil tank enters the gap between a cam rotor and the outside of an air cylinder through an opening formed in the sealing cavity of the hydraulic hose, and the cam rotor and the air cylinder are arranged inside the sealing cavity. According to the automatic prepressing pressure transmission and reduction device, the contact pressure between the cutting blade and the cutting screen of a fluid cutter can be maintained constant; meanwhile, during the entire working state of the fluid cutter, when the wearing capacity of the cutting blade or the cutting screen of the fluid cutting machine exceeds a set value, an automatic prepressing device can release internal hydraulic pressure, and a pressure sensor connected with the automatic prepressing device can issue alarm, so that a worker can replace the worn part.
Description
Technical field
The present invention relates to a kind of pressure transmission and decompressor, more precisely a kind of automatic prepressing compaction forces transmission and decompressor.
Background technique
The fluid cutting machine of prior art is due to motion wearing and tearing between blade and cutting screen, and its contact declines, and causes cutting effect to decline; And in whole working state, the blade of fluid cutting machine cannot remain constant with the contact of cutting screen; The blade of fluid cutting machine and the contact adjustment of cutting screen, need to manually adjust.Cannot accomplish in time, accurately,
Summary of the invention
Due to the above-mentioned shortcoming of prior art, the present invention proposes a kind of automatic prepressing compaction forces transmission and decompressor, and it can solve the above-mentioned shortcoming of prior art.
By the following technical solutions of the present invention:
The transmission of automatic prepressing compaction forces and decompressor, comprise that hydraulic oil is filled with and an air pressure is filled with, described hydraulic oil filling and described air pressure are provided with a hydrovalve between filling with, and the outlet that described hydraulic oil is filled with connects a hydraulic hose, and the opening that the oil that described hydraulic oil is filled with inner is provided with by the Seal cage of described hydraulic hose enters into the gap of cam follower and a cylinder outside, and described cam follower and described cylinder are located at described Seal cage inside.
Also comprise a cylinder head bolt, described cylinder head bolt is located at described Seal cage inside, and the head of described cylinder head bolt is fixed on described cam follower.
The present invention has the following advantages:
The blade of fluid cutting machine of the present invention remains constant with the contact of cutting screen, and be the whole working state at fluid cutting machine, when blade or the cutting screen wear extent of fluid cutting machine exceed specified value, automatic prepressing tightly installs and can discharge internal hydraulic pressure pressure, report to the police by the pressure transducer connecting, change the spare part of wearing and tearing.
Brief description of the drawings
Further set forth the specific embodiment of the present invention below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of automatic prepressing compaction forces transmission and decompressor, comprise that hydraulic oil 3 is filled with and an air pressure fills with 4, described hydraulic oil filling and described air pressure are provided with a hydrovalve 1 between filling with, and the outlet that described hydraulic oil is filled with connects a hydraulic hose 5, and the opening that the oil that described hydraulic oil is filled with inner is provided with by the Seal cage of described hydraulic hose enters into the gap of cam follower and a cylinder outside, and described cam follower and described cylinder are located at described Seal cage inside.
Also comprise a cylinder head bolt, stud bolt is located at described Seal cage inside, and the head of described cylinder head bolt is fixed on described cam follower.
The present invention also comprises a pressure gauge 2, by the convenient pressure that shows of this pressure gauge.
The present invention pressurizes by barometric tank, constant by reduction valve maintenance medium force feed tank internal oil pressure, and sets required pressure; Hydraulic oil, by hydraulic hose and hydraulic pipe line, enters in Seal cage; And enter the gap of cam follower and cylinder outside; Because cam follower and cylinder head bolt maintain static, hydraulic oil promotes cylinder outside so; And power transmission, to knife rest, makes the blade and cutting screen close contact of knife rest, and contact is the pressure of hydraulic oil.
The blade of fluid cutting machine of the present invention remains constant with the contact of cutting screen, and is the whole working state at fluid cutting machine.The contact of the blade of fluid cutting machine and cutting screen, can and not cut the motion wearing and tearing of shielding along with blade, and change.The contact value of the blade of fluid cutting machine and cutting screen, is automatic adjustment completely, and adjusts under the running state of the passable fluid cutting machine of setting value.The blade of fluid cutting machine shields constant contact value with cutting, guarantees the perfect cutting effect of cutting machine.When blade or the cutting screen wear extent of fluid cutting machine exceed specified value, automatic prepressing tightly installs and can discharge internal hydraulic pressure pressure, reports to the police by the pressure transducer connecting, and changes the spare part of wearing and tearing.
