Embodiment
Below by specific embodiment, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of dissimilar steel welding technology evaluation bend specimen test unit, comprise base 9, this base 9 is a base plate, base plate is provided with fixed orifice, can utilize screw bolt and nut that base plate and fixture are fixed, as base plate is fixed on operator's console, make base plate can bear certain deflection force.This test unit also comprises the placement gap of existence for placing sample between 5, two pedestals 5 of two pedestals that are fixed on base 9, is provided with the clamp device that clamps sample in this placement gap; The top and bottom of one of them pedestal 5 are fixed with respectively upper mounting plate 4 and lower installation board 11, upper mounting plate 4 is fixing with pedestal 5 by fastening bolt 12, lower installation board 11 posts and fixes with the base plate face, it is fixing that pedestal 5 is placed in lower installation board 11 up and down installing plates 11, lower installation board 11 and upper mounting plate 4 all an end exceed pedestal 5, be rotatablely equipped with level pressure roller 7 between upper mounting plate 4 and lower installation board 11, so just indirectly realized that 7 rotations of level pressure roller are installed on base 9.These level pressure roller 7 axis are vertical with base plate, in the present embodiment, level pressure roller 7 vertically arranged; Therefore, upper and lower described in the present embodiment vertically arranges with level pressure roller 7 that the time is determined.
And described clamp device comprises cushion block 14 and the force-application block 13 that is positioned over placement space 15, one of them pedestal 5 is provided with the force-applying piece 8 that acts on force-application block 13, and this force-applying piece 8 is horizontally disposed with, and application of force direction is horizontal direction.Described force-applying piece 8 comprises two application of force bolts, and these two application of force bolt vertical spacings are arranged on pedestal 5, and two upper and lower intervals of application of force bolt are arranged on pedestal 5.In the present embodiment, in two pedestals 5, be that force-applying piece 8 is installed on a pedestal 5, fix upper and lower installing plate 11 on another pedestal 5, like this, for operating force-applying piece 8 and rotating the operating space that rotary handle facilitates.Can also only include force-applying piece 8 and force-application block 13 for described clamp device, now omitted cushion block 14, therefore the width of placing gap just broadens, and only needs corresponding change the level pressure roller 7 of various outer diameter and the side bend test that dynamic pressure roller 6 can be applicable to the sample of different size.
Principle of work of the present utility model is: at first after two xenogenesis Plate Weldings, to its sampling, along the direction vertical with weld seam cutting one each wide be the rectangular sample of L, this rectangular thickness is the thickness of sheet material, then unclamp force-applying piece 8, sample is placed on and places in space 15, the thickness direction of its sample is vertical direction, 13 clamping of the Width from sample samples of cushion block 14 and force-application block, and calculate sample and need extend into the length of placing in space 15, guarantee that weld seam on sample is in optimum position, this optimum position is the best plane of symmetry of level pressure roller 7, this the best plane of symmetry is parallel with placement space 15.Now, the residing position of the weld seam of sample is stressed the most even, dynamic pressure roller 6 is when roll extrusion, steel plate laminating level pressure roller 7 roll surfaces of weld seam one side first are out of shape fully, the 7 roll surface redeformations of the then steel plate of opposite side laminating level pressure roller, thereby the Dissimilar Steels distortion of weld seam both sides evenly, guarantees that test result is accurate.
