Problems solved by technology

[0003] In order to eliminate the unevenness and residual stress caused by plastic deformation, it is necessary to straighten the tungsten-molybdenum composite plate to improve the unevenness and eliminate the residual stress in the composite plate. Straightening, if cutting and splitting and then straightening, since the original tungsten-molybdenum composite plate has been cut into 2 sheets, the number of straightening times will also be doubled, resulting in low work efficiency
However, there is currently a lack of a straightening device that can effectively eliminate the unevenness of the tungsten-molybdenum composite panel before shearing and splitting, resulting in large longitudinal bending deformation of the tungsten-molybdenum composite panel after shearing and splitting

Embodiment 1

[0027] The present invention realizes through following technical scheme: as image 3 , Figure 4 , Figure 5 As shown, a straightening device for eliminating unevenness after shearing and splitting of tungsten-molybdenum composite plates includes an entrance straightening machine 1 equipped with A straightening and anti-bending rollers, and an exit straightening machine equipped with B straightening and anti-bending rollers. Machine 2 and the track 3 between the entrance straightener 1 and the exit straightener 2.

[0028] It should be noted that, through the above improvements, first measure the total width of the tungsten-molybdenum composite board, then adjust the distance between the two sections of the straightening and anti-bending roller 13 in the lower row of the entrance leveler 1, and then measure the width of the two tungsten-molybdenum composite boards. The total thickness, adjust the roll gap of the entrance leveler 1 and the exit leveler 2, and finally adjust ...

Embodiment 2

[0030] This embodiment is further optimized on the basis of the above embodiments, such as image 3 As shown, the A straightening and anti-bending rolls include a bite-in roll 11, an ejection roll 14, an upper row of straightening and anti-bending rolls 12 and a lower row of straightening and anti-bending rolls 13. 14. The upper row of straightening and anti-bending rollers 12 and the lower row of straightening and anti-bending rollers 13 have the same size and are arranged crosswise; the bite-in rollers 11, ejection rollers 14 and the upper row of straightening and anti-bending rollers 12 are integral structures ; The lower row of straightening and anti-bending rollers 13 is a two-stage structure.

[0031] The nip-in roller 3 and the ejection roller 4 are exactly single integral cylinder rollers.

[0032] The lower row of straightening and anti-bending rollers 13 adopts a two-stage structure, so that during the straightening process, it can be automatically adjusted accordin...

Embodiment 3

[0035] This embodiment is further optimized on the basis of the above embodiments, such as image 3 , Figure 5 As shown, it also includes the outlet straightening machine 2 frame for installing the outlet straightening machine 2 and the B hydraulic device 5 connected with the front straightening anti-bending roller 21 and the rear row straightening and anti-bending roller 23 respectively. The straightening and anti-bending rollers 21 of the front row and the straightening and anti-bending rollers 23 of the rear row are cylindrical rollers. The diameter of the straightening and anti-bending rollers 21 of the front row is equal to the diameter of the biting roller 11, the diameter of the straightening and anti-bending rollers 23 of the rear row is 1.8 times of the diameter of the straightening and anti-bending rollers 21 of the front row, and the transition rollers The diameter of 22 is 1.3 times of front row straightening anti-bending roller 21 diameters.

[0036] It should ...

Abstract

The invention discloses straightening equipment for eliminating the unevenness of a tungsten-molybdenum composite board after shearing separation. The straightening equipment comprises an inlet straightening machine provided with straightening reverse-bending rolls A, an outlet straightening machine provided with straightening reverse-bending rolls B, and a rail located between the inlet straightening machine and the outlet straightening machine. Compared with the prior art, the straightening equipment disclosed by the invention is capable of effectively eliminating residual stress in the tungsten-molybdenum composite board during a straightening process, a foundation bolt is arranged, and the same height of the rail, the inlet straightening machine and the outlet straightening machine can be kept through adjusting the foundation bolt; and lower-row straightening reverse-bending rolls with two-section structures are arranged, and automatic adjustment can be carried out according to the widths of different tungsten-molybdenum composite boards.

Description

technical field [0001] The invention relates to the technical field of straightening equipment for bimetal composite boards, in particular to a straightening device for eliminating unevenness after shearing and splitting of tungsten-molybdenum composite boards. Background technique [0002] At present, domestic tungsten-molybdenum composite panels are usually produced through explosive welding and hot rolling processes, but no matter what process is used to produce tungsten-molybdenum composite panels, they are made of two different metals, namely tungsten and molybdenum. Due to the large difference in the metal properties of tungsten and molybdenum, especially the expansion coefficient, the composite tungsten-molybdenum composite plate will have a great residual stress inside. In the process of industrial production, in order to improve production efficiency, two tungsten-molybdenum composite plates 1 and 2 are usually stacked together in pairs for high-temperature hot roll...
