Abstract
This utility model is related to a kind of overload protection arrangement of oil cylinder, including oil cylinder body, plunger and fuel tank, and the oil cylinder body is connected with plunger seal, and its innovative point is：Also include pressure transducer, hydraulic valve and connecting tube, the oil cylinder body is provided with pressure relief opening, and the fuel tank is connected with the pressure relief opening pipeline of oil cylinder body by connecting tube, and the pipeline of connecting tube is provided with pressure transducer and hydraulic valve.This utility model can carry out the overload protection of blood pressure lowering to in-oil cylinder oil pressure, and oil cylinder can be made again to play a part of the oil cylinder of vibration and noise reducing in die sinking.
Description
Technical field
This utility model is related to a kind of overload protection arrangement, and in particular to a kind of overload protection arrangement of oil cylinder.
Background technology
In quick die sinking, oil cylinder can produce vibration, noise to existing vulcanizer；And workpiece is during hot-forming,
It is applied on the plunger of oil cylinder because expansion can produce back-pressure, and causes in-oil cylinder oil pressure to raise, once in oil cylinder, oil pressure is too high
May result in oil cylinder damage；Therefore, it is badly in need of a kind of overload protection arrangement of oil cylinder of design, in-oil cylinder oil pressure can be dropped
Pressure, can enable oil cylinder play a part of vibration and noise reducing in quick die sinking again.
The content of the invention
The purpose of this utility model is：A kind of overload protection that blood pressure lowering can be carried out to in-oil cylinder oil pressure is provided, again may be used
So that oil cylinder plays a part of the overload protection arrangement of the oil cylinder of vibration and noise reducing in die sinking, to overcome the deficiencies in the prior art.
In order to achieve the above object, the technical solution of the utility model is：A kind of overload protection arrangement of oil cylinder, including oil
Cylinder body, plunger and fuel tank, the oil cylinder body are connected with plunger seal, and its innovative point is：Also include pressure transducer, liquid
Pressure valve and connecting tube, the oil cylinder body are provided with pressure relief opening, and the fuel tank is by connecting tube and the pressure relief opening pipeline of oil cylinder body
Connection, and the pipeline of connecting tube is provided with pressure transducer and hydraulic valve.
In above-mentioned technical proposal, also including sealing member, between the oil cylinder body and plunger, sealing member is provided with.
The good effect that this utility model has is：After overload protection arrangement using oil cylinder of the present utility model, by
Also include pressure transducer, hydraulic valve and connecting tube in this utility model, the oil cylinder body is provided with pressure relief opening, and the fuel tank leads to
Cross connecting tube to be connected with the pressure relief opening pipeline of oil cylinder body, and the pipeline of connecting tube is provided with pressure transducer and hydraulic valve；When
Vulcanizer by the intrinsic oil pressure of pressure transducer detection oil cylinder, once oil pressure is too high, opens hydraulic pressure during quick die sinking
Valve, reduces oil pressure by hydraulic valve, and the oil pressure after reducing ensure that normal die sinking, so, oil cylinder can not only be entered
Row vibration damping, and noise can be reduced；When workpiece is during hot-forming, if oil pressure is too high in oil cylinder, again by hydraulic pressure
Valve reduces oil pressure, it is to avoid the damage that oil cylinder is caused because oil pressure is too high, extends the service life of oil cylinder.
Description of the drawings
Fig. 1 is a kind of structural representation of specific embodiment of this utility model.
Specific embodiment
Below in conjunction with accompanying drawing and the embodiment for being given, this utility model is further described, but is not limited to
This.
As shown in figure 1, a kind of overload protection arrangement of oil cylinder, including oil cylinder body 1, plunger 2 and fuel tank 3, the oil cylinder
Body 1 is tightly connected with plunger 2, and also including pressure transducer 4, hydraulic valve 5 and connecting tube 6, the oil cylinder body 1 is provided with pressure release
Mouth 1-1, the fuel tank 3 is connected with the pressure relief opening 1-1 pipelines of oil cylinder body 1 by connecting tube 6, and is set on the pipeline of connecting tube 6
There are pressure transducer 4 and hydraulic valve 5.
As shown in figure 1, in order to ensure the good airproof performance between oil cylinder body 1 and plunger 2, also including sealing member 7, the oil
Sealing member 7 is provided between cylinder body 1 and plunger 2.
This utility model may be used on two aspects, i.e.,：
When vulcanizer is during quick die sinking, the intrinsic oil pressure of oil cylinder is detected by pressure transducer, once oil pressure mistake
Height, makes 1 interior part hydraulic oil of oil cylinder body return to fuel tank by pressure relief opening 1-1 by opening hydraulic valve 5, so as to reduce oil
Pressure, and the oil pressure after reducing ensure that normal die sinking；So, big flow fluid in oil cylinder can not only be reduced and returns to fuel tank
When the vibration that produces, and the noise produced when vibrating can be reduced.
When workpiece is during hot-forming, if oil pressure is too high in oil cylinder, drop again by hydraulic valve 5 and pressure relief opening 1-1
Low oil pressure, it is to avoid oil cylinder causes the damage to oil cylinder because oil pressure is too high, extends the service life of oil cylinder.
