End is all made of U shape structure, and spring jack-post 7 is set to the four corners position of vertical pressing plate 5 protrusion.Pressure head 6 is set to vertical pressing plate 5
Lower section, thickness is according to the setting of 6 size of pressure head specified in intercrystalline corrosion standard.
Tourelle includes that two roller bearings being arranged horizontally and mutually in parallel 11 and two pieces are vertical and arranged in parallel
Side support plate 8.Side support plate 8 is fixed on outer panel 2 and lower plate 3, using " convex " font structure, the center of protruding parts
Equipped with positioning runner 9, pressure head 6 can vertically be moved along positioning runner 9；Side support plate 8 is equipped with horizontal roller bearing loose slot
10, the both ends of roller bearing 11 are respectively arranged in the roller bearing loose slot 10 of two sides；Vertical pressing plate 5 can be in side support plate 8 vertically
It is mobile.The both ends of roller bearing 11 are respectively arranged in two pieces of side support plates 8.
The making material yield strength of vertical pressing plate 5 and pressure head 6 is greater than 450MPa；The making material yield strength of roller bearing 11
Greater than 450MPa, the circular shaft and surface that roller bearing 11 is thick using centre, shaft end is thin are smooth.
Working principle: the present invention using manual hydraulic device 4 as the power device bent, rise by manual hydraulic device 4
When, the active force of the axis of elongation acts directly on vertical pressing plate 5, pushes pressure head 6 to move down and sample is bent；When vertical pressing plate
5 when moving down, and spring jack-post 7 plays stable effect, using the active force of spring in 4 release action power of manual hydraulic device
When, it is lifted manual hydraulic device 4 and vertical pressing plate 5 upwards in favor of next bend specimen and does not need manual operation.Vertical pressure
On the one hand plate 5 supports manual hydraulic device 4, on the other hand fixed pressure head 6；Vertical pressing plate 5 and the two sides of side support plate 8 are inlayed,
Control the space that horizontally slips of vertical pressing plate 5, it is ensured that vertical pressing plate 5 vertically moves；Pressure head 6 is have specific thicknesses thin
Plate, the pressure head 6 of a set of different size is customized according to 6 size of difference pressure head specified in intercrystalline corrosion standard, and two sides insertion is collateral
In the positioning runner 9 of fagging 8, transverse direction and the lateral sliding space of pressure head 6 are controlled, moves vertical pressing plate 5 vertically, is controlled
Bending radius is maintained in required precision.11 both ends of roller bearing are assemblied in side support plate 8, and the position of two roller bearings 11 is finely tuned with mandril
It sets, can determine the curved diameter of sample, when sample is bent downwards by pressure head 6, roller bearing 11 can roll therewith, play buffering
Effect, avoids specimen surface from leaving obvious scratch.
The course of work: when being bent to sample, the pressure head 6 for selecting to be suitble to sample is first had to, is fixed under vertical pressing plate 5
Side；The gap between two roller bearings 11 is adjusted ,+2 times of bending diameter of the sample thickness equal to sample is allowed to；Sample is placed on
On two roller bearings 11, position to be bent is placed in the center of two roller bearings 11；Manual hydraulic device is slowly pressed with hand
4, so that its axis of elongation is gradually upwardly into top to outer top panel 1, then proceedes to pressing manual hydraulic device 4, the axis of elongation constantly stretches out, and pushes away
It moves vertical pressing plate 5 to move vertically downward along the side of side support plate 8, while pressure head 6 is also along the positioning runner 9 of side support plate 8
It slowly moves down, is pressed on the crooked position of sample, check that bending position is placed exactly in the underface of pressure head 6 at this time, manually
Hydraulic device 4 continues elongation and acts on vertical pressing plate 5, and band dynamic head 6 continues downwards firmly, and sample is bent, and is involved in two
Between roller bearing 11；After the completion of sample bending, manual hydraulic device 4 stops extending, on the spring jack-post 7 of vertical 5 two sides of pressing plate
Spring-compressed falls in and plays support and stable effect on lower plate 3；The active force of manual hydraulic device 4 is laid down after bending,
Axis of elongation retraction, spring, which slowly rises, lifts vertical pressing plate 5, facilitates the sample for taking out and being bent at this time.
To sum up, the present invention provides the accurate intercrystalline corrosion samples bending dresses of a kind of not only simple but also laborsaving and bending position
Set, this device does not need the support of any electric power, power perpendicular acting when being acted on using manual hydraulic device 4 on bending sample,
It great efforts and does not need artificial laborious；The vertical pressing plate 5 of accurate positioning fixes sample bending position, and accurate sample is bent position
It sets；By adjusting 11 spacing of roller bearing come accurate Control Assay bending diameter, 11 surface of roller bearing is smooth to greatly reduce frictional force, really
The specimen surface protected after bending is smooth without obvious scratch；Spring jack-post 7 on lower plate 3 can effectively be bent in sample
Afterwards, manual hydraulic device 4 is lifted automatically, does not need artificially to lift, it is convenient and labor-saving.
In addition to the implementation, the present invention can also have other embodiments.It is all to use equivalent substitution or equivalent transformation shape
At technical solution, fall within the scope of protection required by the present invention.
