Abstract
The invention discloses an additional heating device of a cold isostatic press, which comprises a steam furnace which is connected with a work cylinder of the cold isostatic press through a steam pipeline, wherein the steam pipeline is provided with two manual steam switches and an electric temperature sense control valve, and the electric temperature sense control valve is connected with an electric temperature detector. By heating up inner wear-resistant pressure emulsified liquid and water in a work cylinder of the cold isostatic press through a steam pipe which is connected with the steam furnace, matching with the two manual steam switches arranged on the steam pipeline and the electric temperature sense control valve arranged between the two manual steam switches, and combining with the connection between the electric temperature detector and the electric temperature sense control valve, the device guarantees the temperature of the inner wear-resistant pressure emulsified liquid and the water to be invariable. After being improved, the device can guarantee the temperature of the water and the hydraulic oil, thereby ensuring resin in a mould to be effectively softened (molten) and enhancing the effective combination between various materials and the resin.
Description
Technical field
The invention belongs to cold isostatic press heating in winter auxiliary equipment technical field, particularly a kind of additional heating device of cold isostatic press.
Background technology
Cold isostatic press is according to pascal's principle, is used for various pulverulent products at each ultrahigh-pressure hydraulic equipment to the super-pressure pressure state compacted under of equalization.Simultaneously, the quenching of high pressure sterilization, medicine that also is used for food got and field of biological pharmacy such as protein activation.Operation principle is that powder is contained in the elastic mould, and puts into ultrahigh pressure vessel, with pump high-pressure liquid medium is injected in the ultrahigh pressure vessel, and stepless action makes the even compression forming of powder in the mould all surface.Cold isostatic press makes identical high-pressure uniform act on the object all surface, and making water is medium, externally applies can to obtain uniform high density parts up to the high pressure of 300MPa, and size is dwindled in proportion, shape invariance.Adopt high accuracy, high-tensile steel wires prestressing force wound form structure, efficiently solve the security under the high-pressure work state; Requirement of safe production is fully satisfied in the protection of booster driving pressure, overpressure protection, manually maltilevel security designs such as unloading pressure protection, explosion protection, mechanical interlocked protection, emergency route protection, outage security protection automatically.Host machine part, hydraulic drive and electrical control division are grouped into.
Because the particularity of functional refractory production technology, factory is provided with the constant indoor temperature system in the working district of each workshop section of system material moulding, guarantees that the working region temperature is between the 30-40 degree.So help the pug resin and other material better organically combines.But we find that goods occurring after annual winter, our goods of arriving back were by the isostatic pressing machine compacting ruptures, bursts, falls the piece phenomenon in the long-term production practice, the ripe base substrate of goods of compacting is close lower, pore is bigger, the antiscour corrosion resistance is poor when steel mill normally uses, and the goods whole service life is lower.That is exactly that the interior hydraulic fluid temperature of hydraulic cylinder is too low, has caused resin can not finely to combine with other material.
Summary of the invention
The invention provides a kind of can guarantee cold isostatic press in the winter time operate as normal, guarantee the static pressure constant product quality, guarantee the normal additional heating device of cold isostatic press of hydraulic cylinder temperature stabilization.
A kind of additional heating device of cold isostatic press, comprise the steam oven that is connected by steam pipeline with calm press working cylinder, described calm press working cylinder comprises the interior rubber-lined cover that contacts with inner wear-resistant pressure emulsified liquid and water, between rubber-lined cover and the outer steel wall hydraulic fluid chamber is set in described, described hydraulic fluid chamber is communicated with circulating oil cylinder by oil pipe, on the described oil pipe hydraulic pump is set, two manual steam switch are set on the described steam pipeline, between described two manual steam switch electron temperature sensing control valve is set, described electron temperature sensing control valve is connected with electronic thermometer in being immersed in wear-resistant pressure emulsified liquid and water.
Described steam pipeline extend in the wear-resistant pressure emulsified liquid and water in the calm press working cylinder by the super heated rubber tube connector.
The present invention heats inside wear-resistant pressure emulsified liquid and water in the calm press working cylinder by the steam pipeline that is connected with steam oven, and, the electron temperature sensing control valve that is provided with between two manual steam switch and two manual steam switch cooperates by being set on the steam pipeline, connect in conjunction with the electronic thermometer that is connected with described electron temperature sensing control valve, guaranteed that inner wear-resistant pressure emulsified liquid and water termostat are constant.Improve the back water temperature, hydraulic fluid temperature is guaranteed, guaranteed in the mould resin effectively softening (thawing) strengthened various materials and combined with the effective of resin.Avoided various goods in the bad demoulding of production process, burst, phenomenon of rupture, the examination volume density improves a lot, intensity also increases, the porosity obviously descends, the anti-erosion of goods and scour resistance all obviously improve, and have prolonged service life.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is described further:
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of additional heating device of cold isostatic press, comprise the steam oven 12 that is communicated with by steam pipeline 4 with calm press working cylinder 14, described calm press working cylinder 14 comprises the interior rubber-lined cover 5 that contacts with inner wear-resistant pressure emulsified liquid and water 7, between rubber-lined cover 5 and the outer steel wall 8 hydraulic fluid chamber 9 is set in described, described hydraulic fluid chamber 9 is communicated with circulating oil cylinder 11 by oil pipe 13, on the described oil pipe 13 hydraulic pump 10 is set, two manual steam switch 2 are set on the described steam pipeline 4, between described two manual steam switch 2 electron temperature sensing control valve 3 is set, described electron temperature sensing control valve 3 is connected with electronic thermometer 6 in being immersed in wear-resistant pressure emulsified liquid and water 7.
Described steam pipeline 4 extend in the wear-resistant pressure emulsified liquid and water 7 in the calm press working cylinder 14 by super heated rubber tube connector 1.
The present invention heats inside wear-resistant pressure emulsified liquid and water in the calm press working cylinder by the steam pipeline that is connected with steam oven, and, the electron temperature sensing control valve that is provided with between two manual steam switch and two manual steam switch cooperates by being set on the steam pipeline, connect in conjunction with the electronic thermometer that is connected with described electron temperature sensing control valve, guaranteed that inner wear-resistant pressure emulsified liquid and water termostat are constant.Improve the back water temperature, hydraulic fluid temperature is guaranteed, guaranteed in the mould resin effectively softening (thawing) strengthened various materials and combined with the effective of resin.Avoided various goods in the bad demoulding of production process, burst, phenomenon of rupture, the examination volume density improves a lot, intensity also increases, the porosity obviously descends, the anti-erosion of goods and scour resistance all obviously improve, and have prolonged service life.
