Description
Technical field
The invention belongs to rubber manufacturing machinery field, be specifically related to a kind of hydraulic system of tire vulcanizing device.
Technical background
Tire vulcanizing device comprises vulcanizer and vulcanizing tank.
The sulfuration of solid tyre at present adopts above-mentioned two kinds of equipment to vulcanize.Limited by hydraulic system, at present no matter which kind of vulcanizing equipment can only provide constant voltage clamp force to vulcanize in sulfidation.But because solid tyre carcass is generous, when constant voltage clamp force is vulcanized, the outer field robber materials of carcass first expands, be introduced into the runner mouth of mould, after the robber materials of carcass inside, expand, after flow to runner mouth, like this because the outer layer rubber raw material swelling stress that the robber materials of carcass inside produces that first expands can not well be discharged, simultaneously because runner mouth cross section blocks or cross section diminishes, the mobility of inner robber materials when sulfuration is also poor, cause solid tyre after sulfuration due to the release of inner rubber raw material expansive force, thereby can cause the quality problems such as solid tyre external crack to produce.Because vulcanizing equipment is for a long time in high-temperature high-pressure state, the service life of equipment, security all can be received impact simultaneously.Again, because vulcanizing equipment keeps the motive energy resources measurement of high pressure needs many for a long time.
Summary of the invention
The object of the present invention is to provide a kind of vulcanizing equipment of realizing can carry out the hydraulic system of a kind of tire vulcanizing device of transformation when sulfuration.This hydraulic system can realize vulcanizing equipment in the existing transformation sulfuration of the compacting of releasing of sulfurating stage; Adopt the vulcanizing equipment of this hydraulic system can significantly improve the vulcanized quality of solid tyre.
In order to realize the present invention, the technical solution used in the present invention is as follows:
A kind of hydraulic system of tire vulcanizing device, it comprises master cylinder pipeline, high pressure oil supply pipeline, low pressure oil supply pipeline, lock ring oil circuit and return line, wherein master cylinder pipeline, high pressure oil supply pipeline, low pressure oil supply pipeline, lock ring oil circuit arrange routinely, it is characterized in that: master cylinder pipeline to return line is provided with one group of pressure-control valve, this pressure-control valve comprises Solenoid ball valve, choke valve, Superimposed relief valve, described Solenoid ball valve and choke valve are connected in series, and Solenoid ball valve, choke valve and Superimposed relief valve are arranged in parallel.
The hydraulic system of above-mentioned a kind of tire vulcanizing device, described master cylinder pipeline is provided with pressure sensor.
The hydraulic system of above-mentioned a kind of tire vulcanizing device, the principle of carrying out pressure variation during its sulfuration is:
Master cylinder pipeline is connected with the master cylinder of vulcanizing equipment.According to sulfuration process requirement, utilize Solenoid ball valve and choke valve to carry out pressure release to adjust master cylinder pressure to master cylinder pipeline; Superimposed relief valve plays maximum pressure safeguard protection effect, Superimposed relief valve releasing pressure automatically master cylinder loine pressure protection master cylinder when system pressure surpasses predetermined pressure.Solenoid ball valve is gathered master cylinder pressure and controlled by electric-control system computer program by the pressure sensor arranging on master cylinder pipeline and opens, and the master cylinder pressure of realizing in sulfidation changes control.
The hydraulic system of a kind of tire vulcanizing device of the present invention, can realize the pressure release adjustment of master cylinder clamp force and control by the pressure-control valve adopting, can realize the transformation sulfuration of tire, can significantly improve the quality of tyre vulcanization, especially the vulcanized quality of solid tyre.
The present invention can be used on vulcanizer and vulcanizing tank.
