Description
Technical field
The present invention relates to a kind of production method of rubber wire cable, particularly a kind of rubber wire cable high-temperature low-pressure steam continuous curing method and device.
Background technology
Rubber wire cable is the more traditional series products of wires and cables industry, and its general use is had many uses having the mobile environment that lays, and is wires and cables industry one big class major product.The method of high temperature and high pressure steam continuous vulcanization is all adopted in the production of existing rubber wire cable, promptly in curing tube, import the high steam more than the 1.0Mpa, utilize the transmission medium of high steam as temperature, the motion of high steam in pipeline plays uniform temperature, in order to avoid because the influence of thermograde makes the cable vulcanization of rubber speed in same cross section change and cause rubber performance to distort.The high-temperature low-pressure steam continuous curing device that adopts as shown in Figure 1, 2, it comprises paying out machine 1, admission machine 2, last hauling machine 3, following hauling machine 4, rubber extrusion main unit 5 and curing tube, curing tube is connected with rubber extrusion main unit 5, curing tube is the pipeline integral body of a UNICOM, is divided into the sulfuration section and the water cooling section that connect each other; There is high steam input pipe 6 upper end of sulfuration section, it is formed by connecting by some curing tubes, and curing tube is formed (as shown in Figure 2) by high voltage bearing stainless-steel seamless pipe 7, the insulation fixed bed 9 that is wrapped in the asbestos heat-insulation layer 8 of steel pipe 7 peripheries and is fixed on asbestos heat-insulation layer 8 peripheries; Sulfuration section is designed to half stretched wire pattern, in order to avoid cable contacts with curing tube cable appearance is scratched in the sulfidation; The water cooling section is designed to be the inclination pattern, and when cable entered into cooling section, the rubber of cable vulcanized, and cable is wiped pipeline can damaged yet; The above high steam of input 0.4Mpa in the pipeline of sulfuration section, cable vulcanizes in being in the sulfuration section of high temperature, hyperbaric environment, temperature in the sulfuration section is shown by thermometer, carries out continuous vulcanization according to the thermometer temperature displayed by manual control steam input quantity; Cooling section adopts water-cooling pattern, and water is shuttling movement in cooling section, and cold water flows out from the upper end (intersection of sulfuration section and water cooling section) of cooling section from lower end (other end of curing tube and the extruder junction) input of cooling section.
During production, concentricity debugging and presentation quality satisfaction when conductor and insulation, after product uniform motion (unwrapping wire, take-up, extrude continuous operation) is produced, curing tube is connected with rubber extrusion main unit 5 sealings, the high steam input pipe of the upper end by sulfuration section is imported high steam in curing tube, realize the continuous vulcanization production in the curing tube of high temperature, high pressure of rubber cable product.
The method of this high temperature and high pressure steam continuous vulcanization, because of the moisture content of mixed rubber, the intensity of electro-insulating rubber, air, the intensity of jacket rubber and the reasons such as thickness of insulation or jacket rubber of one-tenth cable core, when rubber wire cable vulcanizes at the environment of high temperature, high pressure, electric wire suddenlys change to environmental pressure from hyperbaric environment, rubber is in negative pressure state, thereby produce " foaming " or " breaking " of rubber, cause the failure of rubber wire cable production.
Summary of the invention
One of purpose of the present invention is the above-mentioned deficiency that overcomes prior art, and a kind of rubber wire cable high-temperature low-pressure steam continuous curing method is provided.
Technical scheme of the present invention is: a kind of rubber wire cable high-temperature low-pressure steam continuous curing method, it is at curing tube input 0.4Mpa and following low-pressure steam, simultaneously the sulfuration section of curing tube is carried out electrical heating, utilize the transmission medium of low-pressure steam as temperature, the motion of low-pressure steam in pipeline plays uniform temperature, in order to avoid because the influence of thermograde makes the cable vulcanization of rubber speed in same cross section change and cause rubber performance to distort.
The further technical scheme of the present invention is: each the joint curing tube to curing tube sulfuration section carries out merogenesis energising short circuit heating, control is by the temperature of joint curing tube, reach the rubber wire cable sulfuration by the technical process of high temperature, thereby guarantee that rubber wire cable can not make rubber " foaming " or " breaking " because of high pressure to low temperature.
The further again technical scheme of the present invention is: because the continuous vulcanization pipeline is a UNICOM, the water cooling section must insulate with the sulfuration section and separate, and the water cooling section does not need to heat on the one hand, is the security insulation on the other hand.
Two of purpose of the present invention provides a kind of rubber wire cable high-temperature low-pressure steam continuous curing device.
Technical scheme of the present invention is: a kind of rubber wire cable high-temperature low-pressure steam continuous curing device comprises paying out machine, admission machine, last hauling machine, following hauling machine, rubber extrusion main unit and curing tube, curing tube is the pipeline integral body of a UNICOM, be divided into the sulfuration section and the water cooling section that connect each other, there is the high steam input pipe upper end of sulfuration section, it is formed by connecting by some curing tubes, curing tube is by resistant to elevated temperatures stainless-steel seamless pipe, the asbestos heat-insulation layer that is positioned at the steel pipe periphery is formed with the insulation fixed bed that is fixed on asbestos heat-insulation layer periphery, between steel pipe and asbestos heat-insulation layer, cavity is arranged, electric heating tube is arranged in the cavity.
