Description
Technical field
The utility model is related to a kind of breaking device, more particularly, to a kind of bar of laser melting coating built-up welding.
Background technology
The service life of general plate hammer for crusher is short, and the big of consumption, which needs to lay in substantial amounts of spare part, could maintain normal life
Produce production costs high.
The reason for general plate hammer for crusher service life is short typically has two：
One is that the selection of plate hammer for crusher material is improper.General plate hammer for crusher material type selecting is improper, causes hardness and tough
Property is unable to reach technological requirement.And because the limitation shape of cost can not also use the material of higher cost.
Two be that board hammer structure selection is improper.The many working faces of plate hammer for crusher structure type have generous and narrow thin by two
Plant the generous effective wear extenies of big：Have what single head work and double end worked, the single heads for having one side work and double-face working only have
One wear surface double end has two wear surfaces.
Utility model content
The purpose of this utility model is short to solve bar service life in the prior art, and wear surface rapid wear is asked
There is provided a kind of bar of laser melting coating built-up welding for topic.
The utility model is solves the deficiency of above-mentioned technical problem, and the technical scheme used is：
A kind of uniform three rectangular boss on bar of laser melting coating built-up welding, including rotor, the excircle of rotor, boss is remote
From offering rectangular recess, in addition to fan-shaped hammer body on one end of rotor, the one end of fan-shaped hammer body away from its arc surface is to extension
Stretch one section and form the convex body matched with rectangular recess, convex body is fastened in rectangular recess and is pacified fan-shaped hammer body by installation bolt
On boss, it is respectively the first bolt hole and the second spiral shell that two spaced bolts hole are offered on the side wall of rectangular recess
Built-up welding in the semicircle ball recess of several dense distributions, semicircle ball recess is dug on keyhole, the sector of fan-shaped hammer body
There is spherical abrasion-proof stick, being cooperated between the spherical abrasion-proof stick in semicircle ball recess constitutes a wearing layer, the first spiral shell
Spacing between keyhole and the second bolt hole is the radius of spherical abrasion-proof stick, when installation bolt is located in the first bolt hole,
The composition that cooperated between spherical abrasion-proof stick outside semicircle ball recess laciniation is operated, and works as installation bolt
When being located in the second bolt hole, the wearing layer for the composition that cooperated between the spherical abrasion-proof stick inside semicircle ball recess
It is operated.
The through hole matched with bolt hole is offered on described convex body.
Described fan-shaped hammer body is made of high violent cast iron.
Described spherical abrasion-proof stick is made of rich chromium cast iron.
The beneficial effects of the utility model are：The application is provided with several spherical abrasion-proof sticks, and spherical abrasion-proof stick stretches out half
Position outside ball connected in star is first worn, therefore first installation bolt is located in the first bolt hole when installing, spherical wear-resisting
Rod, which stretches out the position outside semicircle ball recess, can to form many structures the same similar to sawtooth on the working face of bar,
The crushing effect of disintegrating machine can so be increased, while mitigating abrasion to increase service life, after completely worn out, will be pacified
When dress bolt is located in the second bolt hole, cooperate what is constituted between the spherical abrasion-proof stick inside semicircle ball recess
Wearing layer, due to being that dense distribution is the equal of to implant one layer of wearing layer, work is adjusted to by installation bolt by wearing layer
Face position, further extends service life.

Embodiment
Shown in Fig. 1, embodiment is as follows：
Uniform three rectangular boss 2, convex on a kind of bar of laser melting coating built-up welding, including rotor 3, the excircle of rotor 3
Platform 2 is evenly distributed on the excircle of rotor 3, and boss 2 offers rectangular recess 201, rectangular recess on one end away from rotor
For what is dug from the one end of boss away from rotor to rotor direction, while boss is run through in heart line direction to rectangular recess in the rotor,
Also include fan-shaped hammer body 1, the fan-shaped one end of hammer body 1 away from its arc surface stretches out one section to be formed to be matched with rectangular recess 201
Convex body, convex body is fastened in rectangular recess 201 and fan-shaped hammer body 1 is arranged on boss 2 by installation bolt 4, and rectangle is recessed
It is respectively the first bolt hole 202 and the second bolt hole 203, fan that two spaced bolts hole are offered on the side wall of groove 201
Built-up welding in the semicircle ball recess 101 of several dense distributions, semicircle ball recess 101 is dug on the sector of shape hammer body 1
There is spherical abrasion-proof stick 5, cooperated between the spherical abrasion-proof stick 5 in semicircle ball recess 101 and constitute a wearing layer, the
Spacing between one bolt hole 202 and the second bolt hole 203 is the radius of spherical abrasion-proof stick 5, when installation bolt 4 is located in first
Cooperated when in bolt hole, between the spherical abrasion-proof stick outside semicircle ball recess 101 and constitute laciniation progress
Work, when installation bolt 4 is located in the second bolt hole, between the spherical abrasion-proof stick inside semicircle ball recess 101
The wearing layer constituted that cooperates is operated, because semicircle ball recess 101 is dense distribution, therefore multiple intensive point phases
When in constituting a face, wearing layer is as constituted.
The through hole matched with bolt hole is offered on described convex body.
Described fan-shaped hammer body 1 is made of high violent cast iron.
Described spherical abrasion-proof stick 5 is made of rich chromium cast iron.
The hardfacing electrode of high-chromium alloy type is used in the utility model, the surfacing layer of this kind of welding rod is generally horse
Family name's body+this tissue morphology of retained austenite+carbide has preferable anti-magic grinding abrasion performance.The Gao Meng used due to liner plate
Steel, the thermal conductivity factor that this results in liner plate is very low, easily produces larger thermal stress and structural stress, therefore again must in welding process
Cooling velocity must be accelerated, carbide is had little time precipitation, welding procedure must use low current, discontinuous welding, weld interpass temperature
It must not exceed 280 DEG C, it is to avoid crackle occur.
Technical scheme and embodiment and non-limiting cited by the utility model, with the skill cited by the utility model
Art scheme and embodiment are equal or effect same approach is all in the range of the utility model is protected.
