The specific embodiment
By reference to the accompanying drawings, the utility model is described in further detail.
As shown in the figure, the utility model two-piece type hammer, it is characterized in that: described hammer is mainly used in the beater grinder, comprise shank spare 11 and tup 12, tup 12 usefulness pins 15 are fixed on the shank spare 11 and by W shape welding manner both are linked together, and a cylindrical openings 16 is arranged on the top 17 of shank spare 11; Downward-sloping shoulder arm 1 and the shoulder arm 2 21 of forming respectively of 2 19, two opposites of opposite 1 and opposite arranged on the described shank spare 11; There is a coupling part 25 below of described shank spare 11, and the thickness of coupling part 25 is littler than the thickness of the parallel surface 1 on shank part 11 tops 17, parallel surface 2 29; The tranverse sectional thickness of described attaching parts 25 reduces at side 1 and side 2 31 places, and the lateral surface 1 of tup 12, lateral surface 2 35 be corresponding parallel surface 1 and the parallel surface 2 29 that is connected to shank spare 11 respectively; There is a drop-center 38 described tup 12 inside, and this groove slides onto the end of shank spare 11 coupling parts 25.The hollow inclined plane 1 of described tup 12 when tup 12 slides onto shank spare 11 the shoulder arm 1 on the corresponding shank spare 11, shoulder arm 2 21 downwards with sliding left.The groove of described tup 12 has a medial surface 41 for 38 li, has circular slot 43 on a flange 42 and the corresponding shank spare 11 to overlap on this medial surface 41 and forms fronts 44.Described round flange 45 coincides when flange 42 is installed in the circular slot 43 with complementary groove 46.Described medial surface 41 have one downwards backward inclined plane 2 49 be connected on the inclined-plane 48 on shank spare 11 fronts 44, inclined plane 2 49 is higher than turning groove 49 A makes inclined plane 2 49 fully contact with inclined-plane 48.The front side wall 50 of described tup 12 and the cross section front side angle of bottom side working face 52 51 wear intensity maximums, front side angle 51 55 the direction wearing and tearing towards the bottom surface backward, front side wall 50 and bottom side working face 52 wearing and tearing backs form curve 58, and 55 downward-sloping inclined planes 1 with tup 12 tips 56, bottom surface contact.There is an oval-shaped opening 64 at 65 places to described shank spare along the rear surface, and pin 15 is by this opening, and tup 12 can take off from opening 64 when the mid portion 70 in the pin 15 was cut, and tup 12 has side 1 and side 2 67.Described pin 15 usefulness W shape welding manners are welded on the amplification annular opening 73 of pin open front place 72.
As shown in the figure, the overall structure of this two-piece type hammer is as indicated above, wherein tup is fixed on the shank spare back by a pin 15 and with W shape welding manner two parts is connected together, though like this under the situation of sharp pounding or working strength also can keep being fixed on the shank spare 11 of head steady when big.Shank spare 11 preferably can be installed to the epitrochanterian type of beater grinder, namely the part of shank spare 11 hollows can be installed on the beater grinder.Generally speaking, rotor is plate-like and has than multiple-rotor or the big supporting pin of diameter, so just can a plurality of hammers be installed at rotor.There is a bigger cylinder opening 16 on the top 17 of shank spare 11, hammer can be installed and fixed on the pin and rotating shaft of described rotor by this opening.
Impacting and grinding that hammer leaf head tip is the most serious position of wearing and tearing in the operation, the most advanced and sophisticated loss of head is very fast, make so periodically change the head tip become must, so the preferred potassium steel of tough and tensile, shock-resistant wearing and tearing in head tip.Most advanced and sophisticated 12 cast inside have a big drop-center 38, and groove can slide onto coupling part 25 ends (as shown in Figure 1) of shank spare 11.Be cast as casting from Fig. 5,6 visible most advanced and sophisticated 12 inclined planes 49 and be higher than turning groove 49A to guarantee inclined plane 48 full contacts on inclined plane 49 and the shank on most advanced and sophisticated 12.The two-piece type hammer is connected on the beater grinder, the front side wall 50 of tup 12 is the position of easy wearing and tearing beyond doubt, front side wall 50 can periodically be worn as working face, especially the cross section front side angle 51 wear intensity maximums of front side wall 50 and bottom side working face 52.And will form as shown in Figure 1 curve 58 after 52 wearing and tearing of the front side wall 50 of tup and bottom side working face, when the tip that the points wear of tup just need renew during to the pars convoluta of curve 58.
It is an important characteristic that the head that weares and teares in this example can exchange and not damage shank spare easily for, for fear of changing shank and in order not take off shank spare when changing tup, a steady pin 15 is installed in the rear portion of tup and shank spare.There are an oval-shaped groove or opening 64 in 65 places to shank spare along the rear surface, and steady pin is by this opening.Shown in Figure 3, cutting torch is along line A-B to downside with to the side 66 and 67 and the welding W position of open front place 72 of pin between them that front side Cheng Jiao cuts away tup, thereby the structural type of the tip 56 of tup 12 has reduced and need have been reduced clipping time by the quality that cutting torch cuts.As shown in Figure 3, during along A and B plane cutting pin 15, when cutting to the mid portion 70 of pin 15, tup part just can be taken off from groove or opening 64, and flange 42 and circular slot 43 can divide and come like this.What deserves to be mentioned is that the shape of the recessing of this example or opening 64 can be other.
In addition, pin 15 is preferably the manganese steel pin, and it can be welded on the annular opening 73 of amplification of open front place 72 of pin (as shown in Figure 3) with W shape welding manner.Elimination be that cylindricality also can be outward other shape, but equal effect will be arranged.Shoulder arm 1 on shank spare 11 and the tip, inclined plane 40, inclined-plane 48, inclined plane 2 49 make contact area increase.When two parts combine (as shown in Figure 1), contact area can reduce positive stressed influence greatly, increases the holding capacity of hammer.
