Abstract
The invention discloses a wear-resisting composite sieve plate, which comprises a concave arc-shaped base plate, sieve holes and an installing base, wherein the concave arc-shaped base plate is made of casting common carbon steel; the sieve holes are arranged on the base plate; the installing base is arranged at the bottom of the base plate; and high manganese alloy plates corresponding to the shapes and the sizes of the sieve holes on the base plate are compounded on the base plate. The wear-resisting composite sieve plate has the advantages of simple structure, high strength, detachment convenience and long service life.
Description
Technical field:
The present invention relates to a kind of Metallurgical Factory jig subset parts, particularly relate to a kind of wear-resisting compound sieve plate.
Background technology:
Metallurgical Factory's jig timesharing, friction is impacted in the motion of material, usually with sieve plate upper surface and sieve aperture edge abrasion, the precision of influence screening, service life is short.At present, the sieve plate of the mining sieve of Metallurgical Factory is the casting of carbon steel or wear-resisting alloy steel mostly.Sieve plate with cast carbon steel is not wear-resisting, and service life is short, changes frequently, and labor strength is big, and screening efficiency is low; With the sieve plate that wear-resisting alloy steel is cast, its cost is high, and economic benefit is low.
Summary of the invention:
The objective of the invention is in order to overcome the shortcoming of prior art, provide a kind of simple in structure, wearability good, long service life, screening precision high, the wear-resisting compound sieve plate being convenient to make.
The technical scheme of the wear-resisting compound sieve plate of the present invention is: wear-resisting compound sieve plate; The arcs of recesses base plate that comprises the ordinary carbon steel casting; Be arranged on the sieve aperture on the base plate; Be arranged on the mount pad of base, it is characterized in that: be compounded with on the described base plate and base plate top sieve hole shape, big or small corresponding high manganese plate.
Described sieve aperture be shaped as strip, described strip sieve aperture has two row's multiple rows, vertically is orderly symmetric arrangement by the arcs of recesses sieve plate.
Undulate structure on the surface longitudinal of described high manganese plate.
The present invention is compounded with and base plate top sieve hole shape, big or small corresponding high manganese plate on the arcs of recesses base plate of ordinary carbon steel casting; Because of the high manganese plate has significant wearability; Particularly after it receives the external carbuncle effect; When plastic deformation, have more significant work hardening tendency, the increase that its hardness can be at double; Again since potassium steel through having inherent integral hardness after the water tough processing, thereby improve the degree of depth of sieve plate wearing layer, the cycle in service life that so can improve sieve plate is more than one times.Simultaneously, can reduce the manufacturing cost of sieve plate again.
Further, described sieve aperture be shaped as strip, described strip sieve aperture has two row's multiple rows; Vertically be orderly symmetric arrangement by the arcs of recesses sieve plate; The employing elongated hole had both helped the casting system of sieve plate, more help, improve screening efficiency; Equate that by screening area microscler sieve aperture can improve 15% than the screening efficiency of garden shape sieve aperture with a kind of specification sieve plate.
Further, undulate structure on the surface longitudinal of described high manganese plate, the compass screen surface blind spot is few, and granule materials is in the process that flows downward along sieve, and is big through the probability in hole, can not get stuck, and screening efficiency is high.
The invention has the beneficial effects as follows: simple in structure, wearability good, long service life, screening precision high, be convenient to make, production cost is low, high efficiency.

The specific embodiment
Like Fig. 1, shown in Figure 2; A kind of wear-resisting compound sieve plate comprises the arcs of recesses base plate 1 that ordinary carbon steel is cast, and is arranged on the sieve aperture 2 on the base plate 1; Be arranged on the mount pad 4 of base plate 1 bottom, be compounded with on the described base plate 1 with base plate 1 on sieve aperture 2 shapes, big or small corresponding high manganese plate 3; Described sieve aperture 2 be shaped as strip, described strip sieve aperture 2 has two row's multiple rows, vertically is orderly symmetric arrangement by the arcs of recesses sieve plate; The working face 5 of described high manganese plate 3 is vertically gone up the undulate structure.
More than specified embodiment of the present invention, but this instance of just lifting for the ease of understanding should not be considered to be limitation of the scope of the invention.Equally, any person of ordinary skill in the field all can make various possible being equal to and change or replacement, but all these changes or replacement all should belong to the protection domain of claim of the present invention according to the description of technical scheme of the present invention and preferred embodiment thereof.
