Embodiment
With reference to embodiment, following embodiments, which are illustrative, are not limited is further illustrated to the utility model
, it is impossible to limit the scope of protection of the utility model with following embodiments.
A kind of metal heated swelling apparatus for demonstrating, as shown in Fig. 1,2,3,4,5, innovation of the present utility model is：
Including bottom plate 14, baffle plate 2, movable plate 9 and burner box 5, the side installation baffle plate of bottom plate, set in spacing slide of bottom plate opposite side
One can be close to baffle plate or the movable plate away from baffle plate, and the movable plate is towards the transparent box that a upper end open is set on the end face of baffle plate
13, the transparent box is towards opening 18 is made in the side wall of baffle plate, and with making a fluting 19 on the movable plate of opening contraposition, this is opened
It is used in groove place test piece 17 from up to down, described be open is stretched into and top pressure is in the strip for one end of metallic rod 4,
The other end top pressure of the metallic rod passes through the placing burning box of support 6 on baffle plate on the bottom plate below metallic rod.
In the present embodiment, the baffle plate is towards making a perforate 15 on the end face of movable plate, one pressure of setting-in in the perforate
Sensor 16, the other end of the metallic rod is crimped on the pressure sensor.
It is T-shaped cross slide way 11 that a section is set on bottom plate, and the cross slide way outer rim is embedded in the movable plate lower end
In the T-shaped guide groove 21 made, a horizontal elongated hole 20 is made on front side of the cross slide way and on the bottom plate of rear side, each
Installing a bolt 12 in elongated hole, the upper ends 7 of two bolts passes from movable plate upper surface again after being penetrated from the movable plate bottom surface,
The upper end of two bolts is set with a nut 8, the bolt positioned at the front side of the fluting and rear side, the two outer rim respectively
Movable plate is set to be slided in bottom plate upper limit after coordinating with nut.Cross slide way is used for the motion track for constraining movable plate, and elongated hole is
Laterally set and slided for bolt in it and move movable plate, after nut check, bolt tenses movable plate the bottom of at
On plate, so as to which movable plate is spacing.
A jacking block 22 is set on the movable plate of the fluting upper end, the jacking block top pressure is in the upper end of test piece and makes test piece be in incline
