Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of fine crusher hammer head in the utility model, is also the structural representation of the tup in fine crusher in the utility model simultaneously.
The name that in figure, each Reference numeral is corresponding is called: 10-hammer handle, 11-rotating shaft installing hole, 20-hammer body, 21-arcwall face, 22-slot, 23-rounding structure, 30-welding region.
Detailed description of the invention
In the utility model fine crusher hammer head embodiment as shown in Figure 1, comprise hammer handle 10 and be fixed on hammer handle 10 for clashing into the hammer body 20 of material, described hammer handle 10 is provided with the rotating shaft installing hole 11 for being connected with the rotating shaft transmission on fine crusher.
Hammer body 20 is as the main stressed member of fine crusher hammer head, adopt extremely hard, high tough tungsten-titanium alloy to make, this tungsten-titanium alloy is the TiC based Cermet hard alloy being bondd by nickel-molybdenum alloy, there is the feature of high strength, high rigidity, high-wearing feature, high impact properties, its hardness is only second to diamond, can effectively strengthen the wearability of hammer body 20.The hammer handle 10 of fine crusher hammer head adopts the casting of 40CrNiMo steel alloy to make, and adds the element such as niobium, vanadium to strengthen, and has good toughness and anti-wear performance.For fear of hammer body 20 and hammer handle 10 nonsynchronous problem of wearing and tearing, hammer body 20 is greater than described hammer handle 10 at rotating shaft installing hole 11 footpaths thickness upwards at described rotating shaft installing hole 11 footpaths width upwards, can play a protective role to hammer handle 10.
Hammer body 20 is provided with the slot 22 inserting away from one end of rotating shaft installing hole 11 for hammer handle 10, and described hammer handle 10 is plugged in described slot 22 and pegs graft and coordinate with tup.Between the bottom land wall of described slot 22 and cell wall, be provided with rounding structure 23, the corresponding end of described hammer handle 10 is provided with the rounding corresponding with described rounding structure 23 and coincide with the inwall of described slot 22, this fit form can improve stress distribution, thereby improves the bond strength between hammer handle 10 and hammer body 20.Described hammer handle 10 and hammer body 20 are to rely on welding between opening's edge and described hammer handle 10 lateral surfaces of described slot 22 to realize to fix, the welding of employing stainless steel electrode, between hammer handle 10 and hammer body 20, forming cross section is leg-of-mutton annular weld zone 30, ensures bonding strength.
In the utility model, fine crusher embodiment comprises rotating shaft and fine crusher hammer head, and the structure of rotating shaft is same as the prior art, and the structure of fine crusher hammer head is identical with the fine crusher hammer head in above-described embodiment, and the concrete structure of fine crusher repeats no more herein.
When production; fine crusher hammer head relies on hammer body 20 to carry out fragmentation to material; there is the features such as high strength, high rigidity, high impact properties due to hammer body 20; can effectively avoid self wearing and tearing; the position that its corresponding size of while is greater than hammer handle 10 can play a protective role to hammer handle 10; avoid tup nonsynchronous problem of wearing and tearing, extend the service life of fine crusher hammer head, reduce Integrated using cost.
In the above-described embodiments; hammer body 20 is provided with slot 22; hammer handle 10 is plugged in slot 22 and pegs graft with hammer body 20 and coordinate; in other embodiment of the present utility model; hammer body 20 also can adopt the mode that plane is combined to realize fixing with hammer handle 10; for example the upper side lower surface of hammer handle 10 is direct and hammer body 20 is welded and fixed, and can rely on equally the part that hammer body 20 is larger than hammer handle 10 sizes to realize the protection to hammer handle 10, avoids wearing and tearing asynchronous.
