Abstract
The invention relates to the technical field of leveling equipment, in particular to a press-down mechanism of a leveler. The press-down mechanism comprises two cross beams, a drive worm gear case, a press-down nut, and a press-down screw, wherein the drive worm gear case is disposed above the two cross beams, the press-down nut is parallelly disposed between the two cross beams, and the press-down screw is disposed inside the press-down nut. A bearing base is disposed at the bottom end of the press-down screw. An output shaft of the drive worm gear case is connected with a connecting hole at the top end of the press-down nut. Tapered roller bearings are symmetrically arranged at the upper end of the press-down nut and between the two cross beams. Thrust roller bearings are arranged at the lower end of the press-down nut and between the two cross beams. The press-down mechanism with the structure has the advantages that press-down and loading stability is effectively improved for the leveler, positioning precision of the press-down mechanism is improved, the worm gear case turns from a special part into a universal part, and production efficiency is improved. The press-down mechanism is mainly applicable to pressing down upper rolls in levelers and uncoiling and leveling lines.
Description
Technical field
The present invention relates to the level(l)ing machine equipment technical field, be specifically related to the level(l)ing machine screw-down.
Background technology
The turbine box underneath type is generally adopted in present general plate smoothing, and screw box and turbine are structure as a whole.This structure is not easy to processing, installs, and nut or the arbitrary damage of turbine must be changed together.And the level(l)ing machine screw-down of prior art is difficult for installing, the location trouble, because turbine box is special purpose parts, so equipment interoperability is poor.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy for installation, improved the positioning accuracy of screw-down, and make worm gear case become general part by special purpose parts, improved the level(l)ing machine screw-down of production efficiency.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: the level(l)ing machine screw-down, comprise two crossbeams, be located at the transmission worm gear case of described two crossbeams top, the parallel screw mandrel of depressing of being located at the middle screw box of described two crossbeams and being located at described screw box inboard, described bottom of depressing screw mandrel is provided with the load wedge, the output shaft of described transmission worm gear case is connected with the connecting hole on screw box top, be arranged with taper roll bearing between the upper end of described screw box and two crossbeams, be arranged with thrust roller bearing between the lower end of described screw box and two crossbeams.
The present invention has following beneficial effect: level(l)ing machine screw-down of the present invention, mainly comprise two crossbeams, be located at the transmission worm gear case of described two crossbeams top, the parallel screw mandrel of depressing of being located at the middle screw box of described two crossbeams and being located at described screw box inboard, wherein, between the top and bottom of screw box and two crossbeams, be arranged with taper roll bearing and thrust roller bearing respectively; The present invention adopts said structure, effectively raises the stability of depressing, loading of level(l)ing machine, has improved the positioning accuracy of screw-down, and has made worm gear case become general part by special purpose parts, has improved production efficiency.The present invention is mainly used in the top roll of level(l)ing machine, levelling machine, uncoiling smoothing line and depresses.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the level(l)ing machine screw-down, comprise two crossbeams 1, be located at described two crossbeam 1 tops transmission worm gear case 2, parallel be located at the screw box 3 in the middle of described two crossbeams 1 and be located at described screw box 3 inboards depress screw mandrel 4, described bottom of depressing screw mandrel 4 is provided with load wedge 5, the output shaft of described transmission worm gear case 2 is connected with the connecting hole on screw box 3 tops, be arranged with taper roll bearing 6 between the upper end of described screw box 3 and two crossbeams 1, be arranged with thrust roller bearing 7 between the lower end of described screw box 3 and two crossbeams 1; In the present embodiment, when top working roll is depressed action, motor rotates left and right sides turbine box, transmission turbine box output shaft is connected with screw box, screw box lower end machining screw, upper end are the connecting hole of transmission turbine box output shaft, drive the screw box rotation, pass to and depress screw mandrel depressing moment of torsion, depress screw mandrel by on the moved cross beam the load wedge drives top roll and do elevating movement.Wherein, taper roll bearing is adopted in the screw box upper end, and the plane thrust roller bearing is adopted in the lower end, the positioning accuracy height, and stability under loading is good; The thrust roller bearing that adopt the lower end can freely be felt relieved, and is conducive to eliminate the morpheme error in the process, improves axiality, the perpendicularity of structure.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, other modifications that those of ordinary skills make technical scheme of the present invention or be equal to replacement, only otherwise break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
