Abstract

The invention discloses a gear cleaning device for a gear roller of a titanium sponge single roller crusher. The device mainly consists of the gear roller (1), a housing case (2) and a gear cleaning knife (3); the gear cleaning knife (3) is fixed at one side of the gear roller (1) of the crusher and is positioned oppositely to a jaw plate; a gap between the knife edge of the gear cleaning knife (3) and gear spaces of the gear roller (1) is adjustable; when the crusher is in work, the gear roller (1) rotates to squeeze with the jaw plate for cutting titanium sponge; and at the same time, the gear cleaning knife (3) picks out the titanium sponge on the gear roller (1), and the principle is similar to the process of metal-cutting. The gear cleaning device provided by the invention has the technical effects that no additional power source or transmission mechanism are needed, and a gear can be cleaned by utilizing the self-power of the crusher; the gear cleaning knife structure is of a combined type, so that the cost is low; gaps between gears can be adjusted according to a practical application situation, so that the capability of cleaning the gear is improved; the gear cleaning knife head is good in thermohardening property and high in strength; and the knife edge of the knife head is additionally provided with a rake angle and a relief angle, so that the force for cleaning the gear is reduced, and the friction is reduced.

Description

A kind of titanium sponge single roll crusher discaling roll pick tooth device

Technical field

The invention belongs to crushing mechanism field, particularly a kind of for titanium sponge single roll crusher discaling roll pick tooth device, for rejecting the titanium sponge of between cog on discaling roll, improve crushing efficiency.

Background technology

The in small, broken bits of non-ferrous metal titanium sponge is last procedure of titanium sponge crushing; more conventional equipment is toothed roller type single roll crusher at present; but this machine is in the time of fragmentation; titanium sponge often can be bonded between the tooth (or tooth) of discaling roll; there is the serious phenomenon such as titanium sponge accumulation, cavernous body destruction; simultaneous temperature raises rapidly, makes titanium sponge generation chemical reaction, is an impediment to the automated production of titanium sponge.

Summary of the invention

For solving above-mentioned disintegrating machine problem, what the invention provides a kind of titanium sponge single roll crusher discaling roll picks tooth device, for rejecting the titanium sponge of between cog on discaling roll, improves crushing efficiency.

The present invention is achieved by following technical solution.

Titanium sponge single roll crusher discaling roll pick tooth device, mainly by discaling roll, casing with pick serrated knife etc. and form; Internal side of shell has square groove, and length and width is all greater than and picks serrated knife, picks in the casing square groove that is arranged on disintegrating machine of serrated knife by bolt, is positioned at a side of discaling roll, relative with the jaw of disintegrating machine; Pick serrated knife tooth top and insert discaling roll teeth groove, and leave certain interval; Adjusting pad is contained in casing and picks between serrated knife, picks the radial distance x of serrated knife to discaling roll for adjusting, and this has determined discaling roll teeth groove and the gap of picking serrated knife profile of tooth apart from x, picks serrated knife cutting edge and can adjust by adjusting pad apart from the gap of discaling roll teeth groove.

When disintegrating machine work, discaling roll rotation, with jaw extruding, shearing titanium sponge, picks serrated knife simultaneously and rejects the titanium sponge on discaling roll, the process of its principle metalloid cutting.

The aforementioned serrated knife that picks is made up of cutter head, adjusting pad, tool rest and screw; Cutter head can be divided into several piece according to the discaling roll length of disintegrating machine, and is fixed by screws on tool rest, at the bottom of cutter head tooth, can slightly exceed tool rest right flank; Tool rest downside has flange, the position of restriction cutter head; Adjusting pad is contained between cutter head and tool rest, picks the tangential distance y of serrated knife to discaling roll for adjusting, and this distance will affect the size of cutter head anterior angle γ, relief angle α.

The material of cutter head is W2Mo9Cr4VCo8, is equivalent to the M42 of the U.S., and heat treatment adopts isothermal quenching technique, and hardness is controlled between 64HRC～66HRC; One side of cutter head has flange, as rake face; Profile of tooth and discaling roll axis section profile of tooth conjugation, anterior angle γ is 6 °～15 °, relief angle α is 2 °～5 °.

Compared with prior art, the technique effect that the present invention reaches is disintegrating machine without increasing extra power source and transmission mechanism, utilizes self power to pick tooth; Pick serrated knife structure and adopt combined type, cost is lower; Inter-lobe clearance can be adjusted according to the actual conditions that use, and has improved the tooth ability of picking; Pick serrated knife cutter head thermohardening good, intensity is high; Cutter edge increases anterior angle, relief angle, picks tooth power and reduces, and friction reduces.
