Description
Technical field
The utility model is a kind of real-time monitoring device of pressing process, and particularly a kind of real-time monitoring device of polytetrafluoroethylene (PTFE) pressing process belongs to the renovation technique of the real-time monitoring device of pressing process.
Background technology
Along with the extensive utilization of construction machinery industry seal, more and more higher to the requirement of polytetrafluoroethylene (PTFE), now just also more and more tighter to the requirement of compression molding.Compression molding is exactly that polyflon is inserted in the die cavity of metal die and pressurizeed, and is pressed into preform, then puts into sintering furnace sintering, then cold cut in addition, obtains polytetrafluoroethylene (PTFE) pressing.
At present, effective Real-Time Monitoring in the pressing process of polytetrafluoroethylene (PTFE), is exactly also in pressing process, to produce recoil to press with regard to having produced a series of quite general problems; Preform produces layering, slight crack, distortion; The goods late detection such as different-thickness need to spend a large amount of energy and performance test not up to standard, have affected the service life and the scrappage that has increased product of product, and the input of relative cost improves.The reason that polytetrafluoroethylene (PTFE) stampings produce is a lot, and the distortion that arranging of dwell time is unreasonable, pressing speed setting does not meet, air can not be discharged in time in resin, method of operating is improper and polytetrafluoroethylpowder powder differential settlement produces etc. all may cause image.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and provides a kind of simple in structure, with low cost, the real-time monitoring device of easy to operate polytetrafluoroethylene (PTFE) pressing process.The utility model solves immature in polytetrafluoroethylene (PTFE) pressing process process, affects the problem of the service condition of product, improves dwell time and pressing speed.
The technical solution of the utility model is: the real-time monitoring device of pressing process of the present utility model, include upper press ring, Pressure gauge, lower pressure ring, the lower part mould of adventitia, the upper part mould of adventitia, core rod, wherein press down the outer lower portion that ring set is contained in core rod, upper press ring is sleeved on the outer upper of core rod, between lower pressure ring and upper press ring, form reinforced region, lower part mould is sleeved on the outside of lower pressure ring, upper part mould is sleeved on the outside of upper press ring, between lower part mould and upper part mould, be connected by connector, and be formed with air cavity between lower part mould and upper part mould, Pressure gauge is installed in the outside of lower part mould or upper part mould, and manometric air inlet communicates with air cavity.
Contact-making surface between above-mentioned lower part mould and upper part mould is also equiped with sealing ring 3.
Above-mentioned connector is threaded connector.
The utility model is owing to adopting the structure that uses movable mould, wherein external mold divides two-layer uniformly, guarantee layered portion air cavity can be discharged air pressure and be arrived Pressure gauge, but outer atmosphere is compressed into less than compound, Minitype pressure gauge is installed at layering position, observe and whether reach force value, can monitor product in real time, time update pressing process parameter, in order to avoid scrapped multi-product, increases the detection in later stage.The utility model is a kind of real-time monitoring device of using in polytetrafluoroethylene (PTFE) pressing process of being applicable to, the utility model can be pinpointed the problems and can be solved a problem promptly in polytetrafluoroethylene (PTFE) pressing process, the utility model just can reach good effect by increasing a small amount of detection means, small investment, easy to use, scrap cost is low, and late detection energy, test rate and cost etc. also reduce greatly.The utility model is that a kind of design is ingenious, function admirable, the real-time monitoring device of convenient and practical pressing process.The utility model is simple in structure, with low cost, easy to operate, is a kind of real-time monitoring device of convenient and practical polytetrafluoroethylene (PTFE) pressing process.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment:
Structural representation of the present utility model as shown in Figure 1, the real-time monitoring device of pressing process of the present utility model, include upper press ring 1, Pressure gauge 2, lower pressure ring 4, the lower part mould 5 of adventitia, the upper part mould 9 of adventitia, core rod 10, wherein descend pressure ring 4 to be sleeved on the outer lower portion of core rod 10, upper press ring 1 is sleeved on the outer upper of core rod 10, between lower pressure ring 4 and upper press ring 1, form reinforced region 8, lower part mould 5 is sleeved on the outside of lower pressure ring 4, upper part mould 9 is sleeved on the outside of upper press ring 1, between lower part mould 5 and upper part mould 9, be connected by connector 6, and be formed with air cavity 7 between lower part mould 5 and upper part mould 9, Pressure gauge 2 is installed in the outside of lower part mould 5 or upper part mould 9, and the air inlet of Pressure gauge 2 communicates with air cavity 7.
For guaranteeing sealing, the contact-making surface between above-mentioned lower part mould 5 and upper part mould 9 is also equiped with sealing ring 3.
In the present embodiment, above-mentioned connector 6 is threaded connector.
Pressing process of the present utility model is as follows: as shown in drawings, the a whole set of mould of the present embodiment cleans up from inside to outside, placement order is: the lower part mould 5 of core rod 10, lower pressure ring 4, external mold, the upper part mould 9 of external mold, after placing, add sealing ring 3, then tighten the upper and lower mould of external mold with connector 6.
Take polyflon or the compound of constant weight, pour equably the reinforced region 8 of wash clean in advance into.Then pave material with instrument, polyflon or compound are evenly distributed in whole die cavity.Reinforced evenly necessary, otherwise can make goods deflection.
Wait to feed in raw material complete, cover upper press ring 1, then slowly pressurize by hydraulic press, do not allow impact type and pressurize.In the process of boosting, carry out 2～4 disjunction pressurizes, air in compound is discharged in time.While boosting to authorized pressure, the back-pressure that declines, is raised to after regulation unit pressure, and pressurize 1～10min makes pressure transmission even, and then slowly pine is pressed, and is down to ejection pressure preform is ejected from die cavity.Pressure in whole pressing process changes and can directly reflect by Pressure gauge 2, can judge that whether the speed, the dwell time etc. that now arrange be feasible, and is that ensuing data are as reference change in time.
The utility model is applicable on the real-time monitoring device of the polytetrafluoroethylene (PTFE) pressing process that is arranged on different-thickness, different compaction procedures.
The utility model has not only solved the immature problem on pressing process, and has improved utilization rate and testing efficiency, and greatly reduces energy and the scrappage of late detection.
