Abstract
The invention discloses a main sliding block component for a large precise cold rolling mill. The main sliding block component comprises a main sliding block body arranged on the large precise cold rolling mill, wherein a first extruding wheel and a second extruding wheel are abreast coupled to the main sliding block body. The main sliding block component is characterized in that: a supporting device for supporting the first extruding wheel and the second extruding wheel is arranged on the main sliding block body. The main sliding block body has the advantages that: under the condition that a connection shaft of the extruding wheels is not thickened, radial stress of the extruding wheels is increased, so that the main feeding rolling force of the large precise cold rolling mill is increased greatly; therefore, the cold rolling mill can be used for rolling under a large force; and furthermore, the whole component has a compact structure, so that the rotation inertia of the extruding wheels is reduced, and the quality of a product is improved.
Description
Technical field
The present invention relates to a kind of accurate Large Scale Cold and roll over machine, especially relate to a kind of master slider assembly of accurate Large Scale Cold rolling machine.
Background technology
Cold rolling technology is the annular workpieces such as bearing ring a kind of new technology processing method at normal temperatures.Cold rolling is a progressively deformation process for circulation accumulation, and annular workpieces blank is subject to the extruding of core roller and calendering roller, and plastic deformation occurs in rotary course, reaches required size and cross sectional shape by the accumulation of many week rotations.In process, drive squeegee roller to approach core roller by master slider, give one, core roller thrust radially, thereby realize, workpiece blank is rotated to extruding, complete rolling moulding.But, because the cold squeegee roller that runs in journey need to provide a very large thrust to core roller, and simultaneously squeegee roller is also subject to the reaction force radially of core roller to it, because this reaction force is very large, make connecting axle on squeegee roller cannot bear this reaction force and damaged.Although someone improves the radial-thrust force of squeegee roller by strengthening the diameter of axle of connecting axle, also increased the size of squeegee roller and master slider, thereby increased the rotary inertia of squeegee roller simultaneously, has affected the quality of product.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of master slider assembly that can strengthen the radial-thrust force of squeegee roller and the accurate Large Scale Cold rolling machine of compact conformation.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of accurate Large Scale Cold is rolled over the master slider assembly of machine, comprise the master slider main body being arranged on precision cold rolled machine, in described master slider main body, be connected with the first squeegee roller and the second squeegee roller that are set up in parallel, in described master slider main body, be provided with the bracing or strutting arrangement that the first described squeegee roller and the second described squeegee roller are played a supporting role.
Described bracing or strutting arrangement comprises upper backgear assembly and the lower back wheel assembly that structure is identical, described upper backgear assembly comprises mount pad, connecting axle, the first backgear and the second backgear, described connecting axle is through described mount pad, between described connecting axle and described mount pad, be fixedly installed bearing, the first described backgear is fixedly installed on one end of described connecting axle, the second described backgear is fixedly installed on the other end of described connecting axle, the first described backgear is mutually circumscribed with the first described squeegee roller, the second described backgear is mutually circumscribed with the second described squeegee roller, between described mount pad and described master slider main body, be provided with and move up and down governor motion.
The described governor motion that moves up and down comprises the hold-down screw and the slide block that are arranged on described mount pad, in described master slider main body, be provided with the chute of vertical direction, described slide block and described chute are slidably matched, and described screw is fixedly connected with described master slider main body through described slide block.
Compared with prior art, advantage of the present invention is the bracing or strutting arrangement of the first squeegee roller and the second squeegee roller being played a supporting role owing to being provided with in master slider main body, under the condition of the connecting axle of not overstriking squeegee roller, strengthen the radial-thrust force of squeegee roller, greatly improve accurate Large Scale Cold and rolled over the spreading power of owner's feeding, made cold rolling machine can carry out powerful spreading; And the compact conformation of whole assembly, has reduced the rotary inertia of squeegee roller, has improved the quality of product, it is convenient to make to install and use, and greatly reduces manufacturing cost.
