Description
The utility model relates to a kind of instrument of testing usefulness, particularly relates to a kind of no oil seal type sulfuration experimental machine.
As shown in Figure 1, general sulfuration experimental machine is to be provided with a patrix 2 above a counterdie 1, this counterdie 1 is arranged on the base 101,2 of patrixes are oppositely arranged on a suspension 201 bottoms, and on being somebody's turn to do, counterdie 2,1 opposite face respectively convexes with on one, protruding down seat 202,102, this epirelief seat 202 is provided with a die joint 202 ' and a downward opening upper mould cave 202 on one "; the protruding seat 102 of this time then is provided with die joint 102 ' and opening die cavity once 102 up ", these base 102 belows are equiped with a driving shaft 3 again, be horizontally set with a connecting rod 4 on this driving shaft 3 and a yaw drive 5 is connected, and be equiped with a tester for torque 401 on this connecting rod 4, pass through said structure, on tested material is placed on, following die cavity 202 "; 102 " between, and make, counterdie 2,1 mutual closing and when forming mold closing, should go up between die joint 202 ' and the following die joint 102 ' and only keep a minimum gap, and make its upper mould cave 202 " with following die cavity 102 " constitute a die cavity I, this tested material then is to fill up whole die cavity I, when the effect in this gap is that mould 1 relative patrix 2 rotates instantly again, on it, following die joint 202 ', 102 ' can directly not produce abrasion, utilize this yaw drive 5 drive link 4 and driving shaft 3, make counterdie 1 produce back and forth swinging of fixed angle with respect to patrix 2, and this patrix 2 is own and motionless, to go up, counterdie 2,1 heating makes the vulcanizing agent in the tested material begin reaction, so the number that macromolecule is built bridge in the tested material increases gradually, the spring rate of tested material is also more and more higher, it is also increasing in order to resist the moment of torsion that produced of distortion that swings, measure this torque value via this tester for torque 401 again, and the time dependent curve of this torque value has just been represented its state of cure (vulcanization).
Though, utilize above-mentioned sulfuration experimental machine can measure the state of cure (vulcanization) of tested material, but, as shown in Figure 2, when test, generally be that the volume that impossible go accurately to measure the die cavity I is placed tested material just, be placed on but get many slightly tested materials, following die cavity 202 "; 102 " in, on making, counterdie 2,1 when forming mold closing in mutual closing, this tested material can fill up whole die cavity I, remaining flash is then by last, following die joint 202 ', gap between 102 ' spills into, protruding down seat 202,102 outsides, cause, counterdie 2, produce gluing between 1 opposite face, and have influence on measured torque value.
In order to improve this shortcoming, another kind of sulfuration experimental machine is abroad arranged, as shown in Figure 3, be above a counterdie 6, to be provided with a patrix 7, this counterdie 6 is arranged on the base 601,7 of patrixes are oppositely arranged on a suspension 701 bottoms, and on being somebody's turn to do, counterdie 7,6 opposite faces respectively convex with on one, protruding down seat 702,602, on being somebody's turn to do, protruding down seat 702,602 opposite faces then respectively are formed with on one again, following die cavity 702 ', 602 ', on being somebody's turn to do again, protruding down seat 702,602 outsides respectively are provided with on one, lower cover 9,8, this lower cover 8 is to make hollow ring girth sheets shape, its inside is provided with circular hole 801, this time circular hole 801 top end opening places are formed with and from bottom to top enlarge the guide face once 802 of inclination gradually, this time circular hole 801 is set in following protruding seat 602 outsides of counterdie 6, and its top is provided with oil sealing 803, so that sealing between the following protruding seat 602 of counterdie 6 and the lower cover 8, these lower cover 8 bindings are fixed on the base 601, and its pre-position is provided with cushion space 804, and this upper cover plate 9 has symmetrical shape with lower cover 8, structure, and also make hollow ring girth sheets shape, its inside is provided with circular hole 901 on, should go up circular hole 901 bottom end opening places be formed with from top to bottom enlarge gradually one on guide face 902, should go up epirelief seat 702 outsides that circular hole 901 is set in patrix 7, and its bottom is provided with oil sealing 903 on, so that sealing between the epirelief seat 702 of patrix 7 and the upper cover plate 9, these upper cover plate 9 bindings are fixed on the suspension 701, and its pre-position is provided with cushion space 904 on, these counterdie 6 belows are provided with a yaw drive again, this yaw drive makes counterdie 6 produce back and forth swinging of fixed angle with respect to patrix 7, but this lower cover 8 can not swing thereupon but be stationary state, this patrix 7 does not swing yet, and its top is equiped with a tester for torque 703, borrow this tester for torque 703 can measure the state of cure (vulcanization) of tested material, by said structure, because of it is provided with, lower cover 9,8, so when last, counterdie 7,6 mutual closings and when forming mold closing, this tested material can fill up whole die cavity II, remaining flash then spills into, lower cover 9, on 8, following cushion space 904,804 li, and on, lower cover 9,8 with last, counterdie 7,6 separate, therefore can not have influence on the measurement of tester for torque, though this kind sulfuration experimental machine has really been improved the flash problem, make it to record state of cure (vulcanization) more accurately, yet, on preventing that flash from entering, protruding down seat 702,602 with last, lower cover 9, slit between 8, and respectively be provided with, following oil sealing 903,803, but on being somebody's turn to do, following oil sealing 903,803 but have aging or pushed by flash and the shortcoming of being out of shape, and replacing with also very trouble, so increased difficulty and cost in many maintenances, on should how having vulcanized experimental machine again, lower cover 9,8 members such as grade make manufacturing cost also increase much thus.
