[specific embodiment]
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of universal testing machine branch roll-type bending pressurizing unit, as shown in Figure 1, including being installed on universal testing machine to use
In the lower support mechanism for supporting steel plate 7 to be measured and upper pressure mechanism for pressing to steel plate 7 to be measured；
Lower support mechanism includes support frame 6, and support frame 6 is fixedly mounted on universal testing machine, and universal test can be used
The original support frame of machine.It is fixedly mounted on support frame 6 there are two fixed branch roller 5 disposed in parallel, two fixed branch rollers 5 are set vertically
Set and length be identical, guarantee installation lower platen 4 after, lower platen 4 be it is horizontal, lower platen 4 is for the installation in extrusion process
On two fixed branch rollers 5.Spacing is needed between two fixed branch rollers 5, spacing is used to accommodate steel plate to be measured 7 after bending,
Therefore, the spacing between two fixed branch rollers 5 is greater than 2a, and a is the thickness of steel plate 7 to be measured, a > 0.Each 5 top of fixed branch roller
It is hemispherical, there are two hemispherical locating slot, each hemispherical locating slot is used to accommodate and correspond to for setting on 4 bottom surface of lower platen
The top of fixed branch roller 5.
Two fixed 5 tops of branch roller are detachably equipped with lower platen 4, and lower platen 4 is curved for squeezing in extrusion process
Steel plate to be measured 7 after song, when dismantling, lower platen 4 is, two fixed branch rollers 5 can directly support steel plate 7 to be measured.
Upper pressure mechanism includes being connected with the top board 3 disposed in parallel of lower platen 4, top board 3 by branch bending pressure head 2
Power device 1 is connected to be mounted on branch roll-type pressure head 2 when top board 3 is used for extrusion process.Top board 3 is used for and lower platen 4
Cooperation, steel plate 7 to be measured after bending is squeezed, until meeting testing requirements, therefore, top board 3 also requires to protect when squeezing
Water holding is flat, to meet testing requirements.
Pressure head connecting hole is offered on top board 3, is connected by pressure head connecting hole with branch bending pressure head 2, according to big
