Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs 1-4, a kind of magnetorheological fluid bradyseism stamping device, including under casing 12, hang plate 7 and workbench 5, it is described
It is fixedly installed with electric telescopic rod 11 above under casing 12, is fixedly installed with connecting rod 10 on front side of 11 top of electric telescopic rod,
10 front end of connecting rod is fixedly installed with front round rod 1, and 1 lower end of front round rod is fixedly installed with top plate 2, under the top plate 2
Side is fixedly installed with link block 15, and inside is fixedly installed with vibration-absorptive material block 16, the link block 15 among the link block 15
Intermediate lower end is detachably equipped with upper mold 17, and 2 four jiaos of lower sections of the top plate are fixedly installed with telescopic rod 3,3 lower end of telescopic rod
It is fixedly connected with 5 upper surface of workbench, lower die 13, the intermediate two sides of the workbench 5 is detachably installed among the workbench 5
Material pressing plate 4 detachably is installed, the 5 lower section two sides of workbench are fixedly installed with wedge block 6, open among the hang plate 7
Equipped with sliding slot 14,6 lower end of wedge block is slidably connected with sliding slot 14, is fixedly installed with piston rod 19 below the hang plate 7,
19 lower end of piston rod is fixedly installed with piston 20, and 20 mid-wrap of piston is equipped with coil 21, outside the piston 20
