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 the tooth device

Technical field

The invention belongs to the crushing mechanism field, particularly a kind of be used for titanium sponge single roll crusher discaling roll pick the tooth device, be used to reject the titanium sponge of between cog on the 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; Equipment at present relatively more commonly used is discaling roll formula single roll crusher, but this machine is when fragmentation, and titanium sponge regular meeting is bonded between the tooth (or tooth) of discaling roll; Serious phenomenon such as titanium sponge accumulation, cavernous body destruction appears; 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 the tooth device, is used to reject the titanium sponge of between cog on the discaling roll, improves crushing efficiency.

The present invention is achieved through following technical scheme.

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

During disintegrating machine work, the discaling roll rotation with jaw extruding, shearing titanium sponge, is picked serrated knife simultaneously and is rejected the titanium sponge on the 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 on the tool rest through screw, can slightly exceed the tool rest right flank at the bottom of the cutter head tooth; The tool rest downside has flange, the position of restriction cutter head; Adjusting pad is contained between cutter head and the tool rest, is used to adjust pick the tangential distance y of serrated knife to discaling roll, and this distance will influence 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 isothermal quenching technique is adopted in heat treatment, and Hardness Control is 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 that disintegrating machine need not to increase additional drive power and transmission mechanism, utilizes self power to pick tooth; Pick the serrated knife structure and adopt combined type, cost is lower; Inter-lobe clearance can be adjusted according to the actual conditions of using, and has improved the tooth ability of picking; It is good to pick serrated knife cutter head thermohardening, and intensity is high; Cutter edge increases anterior angle, relief angle, picks tooth power and reduces, and friction reduces.
