Description
Technical field
The present invention relates to Material Field, a kind of specifically special, wear-resistant ceramic material.
Background technology
Grinder hammerhead is namely hammer head of hammer crusher, and tup is one of hammer mill kernel component, arrangement
On the hammer axis of crusher rotor, tup directly hits material when crusher runs at high speed, and finished breaking is into suitable material
Granularity.
In order to improve the service life of tup and service efficiency, majority is alloy tup in the tup used on the market now
And composite hammer head, alloy tup is mainly based on manganese alloy, such tup shock resistance is strong, not easy to break, but case hardness
Low, wear-resisting property is weak, and service life is short.Composite hammer head refers to that installation position uses high tenacity, and low wear-resistant material, broken position is
The high rigidity such as high chromium, high abrasion material, composite hammer head are better than manganese alloy tup, but cost in terms of shock resistance and wear-resisting property
High price is expensive, and the high chromium material part at broken position has major part not use, and causes excessively to waste.
The content of the invention
The purpose of the present invention is on the premise of high rigidity is retained, solving the not wear-resisting of existing tup, cost is high, wastes tight
The situation of weight.
To achieve these goals, this programme is realized using following technological means：
A kind of grinder hammerhead, including the tup of umbrella cover and hammer handle, the hammer is being above provided with through hole for installation, institute
State tup surface and be provided with several longitudinal grooves and some horizontal grooves, longitudinal fluting and transverse concave groove are by tup table
Face is divided into several concaveconvex structures, welding windrow is provided with each described groove, the height of the welding windrow is at least
Maintain an equal level with tup surface, the welding windrow is welded as a whole with tup.
In the above-mentioned technical solutions, the height of the welding windrow is higher than tup surface.
In the above-mentioned technical solutions, after the groove welding of the welding windrow and tup, the welding windrow and tup table
Concaveconvex structure is formed between face.
In the above-mentioned technical solutions, the welding windrow is tungsten carbide filler rod.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
The utility model is using this technique for welding windrow so that covers one layer of special gold on original tup surface
Belong to, improve the hardness of tup, in use, timely particulate metal is lost in collision process, it is only necessary to will be lost
Place replace and may insure the use of whole tup.
For with traditional tup using overall particulate metal casting, this programme has saved substantial amounts of material, subtracts
Lacked waste, and this programme can repeatedly repair in actual use after reuse, greatly improve work effect
Rate；There is promotional value very much.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is the floor map of tup；
Fig. 2 is the side schematic view of tup；
Fig. 3, Fig. 4 are the schematic diagrames for filling solder；
Wherein：1 is tup protrusion, and 2 be groove, and 3 be solder.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
The tup of this programme is a shape into umbrella cover, and hammer is being integrated casting, the founding materials of use
For manganese alloy material.Because the physical characteristic of manganese alloy material determines that it does not possess good wearability, it is therefore desirable to is hammering into shape
Head surface carries out secondary operation processing.Traditional method is to carry out monoblock cast using special metal so that tup possesses good
Good collision, but the hoe of this monoblock cast, once collision surface launching damage, cannot use, and can not repair, need
Integral replacing is wanted, overall service efficiency is not high enough.
As shown in Figure 1 and Figure 2, this programme combines a kind of improvement hammehead structure proposed on the basis of existing hammehead structure,
Cast, the impingement area integrally casting of tup is shaped so that impingement area surface forms some using manganese alloy material first
A rough structure.Can also be after monoblock cast, lower ram surface is cut, can with several grooves of transverse cuts,
Then several rough structures are formed in several longitudinally cutting grooves, transverse concave groove and longitudinal fluting intersection.In order to
Further operating procedure, the depth of groove need 3-10mm, and width needs 3-8mm.
In order to enable tup surface possesses good collision, it is therefore desirable to special gold is carried out in the groove on tup surface
The filling of category, this programme are job-hoped according to physical characteristic using tungsten carbide filler rod, and welding windrow is welded in groove and hammer
Head is welded as a whole, as shown in figure 3, welding windrow can be selected to maintain an equal level to form a smooth impingement area with tup surface, when
Right this tup can play good collision effect, but this structure is not optimal structure, because touching
It is possible to that tup body can be damaged to during hitting.
Therefore in the welding process of welding windrow, as shown in Figure 4 so that height of the height of solder higher than the surface of tup
Degree so that tup surface is uneven structure after the completion of welding, and stretch out tup surface is welding windrow, like this,
It is solder first with the material that is broken in collision process.
In the present solution, after the solder in tup groove is worn serious, it can directly be replaced, be avoided traditional
The situation of whole tup can only be replaced once serious wear, and solder is to be stacked into by welding on tup, implements work
Skill is very simple, very low compared to monoblock cast cost.
In the manufacturing process of whole tup, using tungsten carbide filler rod, (tungstenic amount reaches windrow：40-50%), heap weldering body
Higher than 0.5-3mm of tup body；Tup body is manganese alloy material, and manganese content is 5-20%；Before welding welding rod must 300-
60 minutes are kept the temperature under 350 DEG C of temperature conditionss, tup must preheat, and preheating temperature is：400—500℃.
The invention is not limited in foregoing embodiment.The present invention, which expands to, any in the present specification to be disclosed
New feature or any new combination, and disclose any new method or process the step of or any new combination.
