Embodiment
Refer to Fig. 1 to Fig. 3, the utility model proposes the high power stress test of a kind of elastomeric material and control tool, it comprises upper clamping device 19, intermediate plate 21, four lower clamping device 23, rhizoid bar 25, feed screw nut 27, sleeve 29, crank, 31, two steel rulers 33 of 17, four, two bases, 11, base plate, 13, two guide pillars, 15, top board.
Two bases 11 are fixedly mounted in the bottom surface at the two ends, left and right of base plate 13 with bolt so that base plate 13 is placed stablely.
Two parallel ground of guide pillar 15 are vertically installed on base 13.
The bottom of two guide pillars 15 fixedly mounts on base 13.
Top board 17 is fixedly mounted on the top of two guide pillars 15.
On the face, front side of top board 17, equidistant intervals has offered four rectangular tanks 172.
Four upper clamping devices 19 are arranged in four tanks 172 of top board 17.
Upper clamping device 19 comprises four guideposts, 191, cover plate, 193, clamping plate, 195, set nut 197.
The insertion of four guideposts 191 is arranged on the position in four corners of the tank 172 of this top board 17.
Cover plate 193 is arranged on the front end of four guideposts 191.
Clamping plate 195 are positioned at the centre of four guideposts 191.
Set nut 197 is through cover plate 193, and set nut 197 is threaded with clamping plate 195.
During work, being placed between cover plate 193 and clamping plate 195 by the upper end of an EPDM sheet material 1000, then twist set nut 197 clockwise, clamping plate 195 move to the direction of cover plate 193, clamp this EPDM sheet material 1000. When unclamping, counter-clockwise rotation set nut 197, clamping plate 195 move to the direction away from cover plate 193, can take out this EPDM sheet material 1000.
Two guide pillars 15 pass from intermediate plate 21, and intermediate plate 21 slides up and down along two guide pillars 15, and intermediate plate 21 is between base plate 11 and top board 17.
On the face, front side of intermediate plate 21, equidistant intervals has offered four chutes 211.
Four lower clamping devices 23 are arranged on intermediate plate 21, lay respectively at the lower section of four upper clamping devices 19.
Lower clamping device 23 comprises backing plate 231, locking board 233, locating dowel 235, baffle plate 237.
Backing plate 231 is plugged in chute 211, and backing plate 231 slides up and down in chute 231.
Locking board 233 bolt (non-label) is locked on backing plate 231.
During work, the lower end of this EPDM sheet material 1000 is placed between backing plate 231 and locking board 233, then securing bolt, clamps this EPDM sheet material 1000. When unclamping, unclamp bolt, this EPDM sheet material 1000 can be taken out.
Cover plate 193 and each own surface of clamping plate 195, facing to the other side, these two surfaces are equipped with uneven fin (not shown), can increase frictional force, make the EPDM sheet material 1000 not easily landing because of stretching.
Backing plate 231 and locking board 233 also facing to the other side, these two surfaces are also equipped with uneven fin (not shown), can increase frictional force, make the EPDM sheet material 1000 not easily landing because of stretching in each own surface.

Crank 31 is fixedly connected with the top of this screw mandrel 25.
Two steel rulers 33 vertically are installed on base 13.
During work, first four the EPDM sheet materials 1000 being in free state are clamped between clamping device 19 and four lower clamping devices 23 respectively on four, shake crank 31, screw mandrel 25 rotates, feed screw nut 27 moves downward along screw mandrel 25, driving this intermediate plate 21 to move downward, therefore four lower clamping devices 23 move downward thereupon, and four EPDM sheet materials 1000 are constantly elongated. By observing steel ruler 33, it is possible to the amount of tension of record four EPDM sheet materials 1000.
The utility model has following useful effect:
1, after the high power stress test applying the utility model elastomeric material controls tool, it is not necessary to make finished product tubing, only just can test the high-temperature storage characteristics under high power stress and low temperature rebound performance in advance by sizing material compressing tablet, it is to increase the characteristic of working efficiency and yield rate.
2, the high power stress test of the utility model elastomeric material controls tool, it is possible to reach precise positioning, once tests multiple sample.
