Abstract

The utility model discloses a novel hammer crusher hammer, it includes the antifriction bearing of equipartition on the circumference inner circle and outer lane, castingin potassium steel between outer lane and the inner circle, the outer lane cladding has uses the hammer block of potassium steel as the base member, hammer block end profile of surface is circular, and this circular shape centre of a circle is concentric with the inner circle, the gusset also uses potassium steel as the base member, with three hammer block even as an organic whole, the outline of gusset is the circular arc curve to it is tangent with the hammer block. Use potassium steel old and useless bearing of castingin in as the hammer block of base member, the cracked phenomenon of hammer block has been avoided to existing effect, has lengthened life again, the old and useless bearing of castingin has greatly reduced manufacturing cost, accords with circular economy's theory, three inner circle all can regard as the pinhole articulated with rotor block round pin axle, and when being used for reversible hammer crusher, the ore all can be struck in the hammer block both sides, and its life fairly prolongs the sixfold, has greatly reduced use cost, has improved economic benefits.

Description

A kind of Novel hammer rusher tup

Technical field

The utility model is related to a kind of Novel hammer rusher tup.

Background technology

Hammer mill is lime stone in small, broken bits in the industrial departments such as metallurgy, building materials, chemical industry and water power, coal or other are medium hard One of capital equipment of brittle material below spending.Have that reduction ratio is big, production capacity is high, structure is advanced, dependable performance, work flat Surely, energy consumption is low and the features such as epigranular.Hammer mill divides reversible and two kinds of unidirectional type, reversible hammer mill Rotor is reversible, is generally used in small, broken bits；The rotor of unidirectional type hammer mill is irreversible, broken in being generally used for.Machine is using After a period of time, the one side of tup work has worn out, and the liner plate of rotor side and grid section also have certain abrasion, at this moment permissible Stop motor reversal connection, at this moment rotor reverse, the unworn one side of tup reforms into working face, and is not worn and torn using opposite side Grid section and liner plate.Tup is installed can use on two sides, reduces the set-up time, improve operating efficiency.

Currently available technology hammer head of hammer crusher one end is pin-and-hole, on the hinged bearing pin being suspended on rotor block, the other end Hit ore as tup, when tup weares and teares to a certain extent, that is, entirety is scrapped, and stock utilization is low.

Utility model content

The utility model, in order to solve the above problems, provides a kind of Novel hammer rusher tup.

The utility model solves its technical problem and be employed technical scheme comprise that：A kind of Novel hammer rusher tup, bag Include inner ring and the outer ring of the rolling bearing being distributed on circumference, castingin potassium steel between described outer ring and inner ring, described outer ring bag It is covered with the hammer body with potassium steel as matrix；Described hammer body end profile is circle, and this circular center of circle is concentric with inner ring；Three institutes State hammer body to be connected as a single entity by gusset, also with potassium steel as matrix, the outline of described gusset is circular curve to described gusset, and with Hammer body is tangent；The thickness of described gusset is less than the thickness of hammer body.

Further, the thickness of described hammer body is equal to the thickness of outer ring.

Further, the wall thickness of described inner ring is between 10～15mm.

The beneficial effects of the utility model are：Due to adopting said structure, make to act on the impact force action line on hammer body Vibration and noise, Extending Rotor bearing service life can be reduced essentially by the bearing inner race center of circle being equivalent to center of impact； The waste and old bearing of castingin in hammer body with potassium steel as matrix, both effectively prevent the phenomenon of hammer body fracture, had extended use again Life-span；The waste and old bearing of castingin greatly reduces manufacturing cost, meets the theory of recycling economy；Three inner rings all can as pin-and-hole with Rotor block hinge, when for reversible hammer mill, ore all can be hit in hammer body both sides, and its service life is quite prolonged Long six times, greatly reduce use cost, improve economic benefit.

Brief description

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

Fig. 1 is the utility model structural representation；

Fig. 2 is the sectional view of Figure 1A-A.

Specific embodiment

As depicted in figs. 1 and 2, a kind of Novel hammer rusher tup, interior including the rolling bearing being distributed on circumference Circle 2 and outer ring 3, castingin potassium steel between described outer ring 3 and inner ring 2, described outer ring 3 is coated with the hammer body with potassium steel as matrix 1；Described hammer body 1 end profile is circle, and this circular center of circle is concentric with inner ring 2；Three described hammer bodies 1 are linked as one by gusset 4 Body, also with potassium steel as matrix, the outline of described gusset 4 is circular curve to described gusset 4, and tangent with hammer body 1.

For the ease of casting, the thickness of described gusset 4 is less than the thickness of hammer body 1, and the thickness of described hammer body 1 is equal to outer ring 3 Thickness.

In order to proof strength requires, the wall thickness of described inner ring 2 is between 10～15mm.

Hammer body 1 selects hardness high, has the high manganese steel material of certain wearability again, the chemical composition of its design potassium steel Mass fraction：1.16%～1.27%C, 13.06%～14.28%Mn, 0.52%～0.84%Si, 1.91%～2.43% Cr, 0.03%～0.05%S, 0.04%～0.06%P, 0.19%～0.25%Re, 80.82%～83.09%Fe.

Outer ring and inner ring are waste and old bearing, put in evaporative pattern after pulling down cleaning, pour into a mould potassium steel solution, make both be in Metallurgical binding.

Bearing steel has a height and uniform hardness and wearability, and high elastic limit, tup can be greatly improved wear-resisting Property, improve service life.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all in this practicality Within new spirit and principle, any modification, equivalent substitution and improvement made etc., should be included in guarantor of the present utility model Within the scope of shield.
