The keyway of up and down direction, positioning key 12 is equipped in keyway, and positioning key 12 is fixed on hammer body 1 and/or hammering head 3.
The trapezoid boss 11 be isosceles trapezoidal structure, the waist of the isosceles trapezoid of trapezoid boss 11 and bottom edge with it is trapezoidal
Groove 32 forms interference fit.
12 top of positioning key is fixed on hammer body 1 by a bolt 5, and the lower part of positioning key 12 passes through another bolt 5
It is fixed on hammering head 3, the fixed structure having the same of positioning key 12 of left and right side.
Dismountable bushing 4 is fixed in mounting hole, bushing 4 is fixedly connected with the drive shaft of steel scrap quartering hammer.
Interference connection carrys out stationary bushing 4 in mounting hole.
The structure of dismountable bushing 4 is fixed in mounting hole are as follows: the both ends of bushing 4 are fixed on the gland on hammer body 1
It compresses.
The left and right end of 3 lower end of hammering head is provided with chamfering 31.
Hammer body 1 is made of ordinary carbon steel material, and hammering head 3 is made of wear-resisting carbon steel.
The positive advantageous effects of the utility model are:
1. hammer body is chimeric using trapezoid boss and trapezoidal groove with hammering head, bonding strength is big, trapezoid boss and trapezoidal recessed
Slot is unlikely to deform, and the repeatable replacement of hammering head uses；
2. installing positioning key using keyway, prevent hammer body and hammering head from occurring in impact process along front-rear direction wrong
Position；
3. being fixed with replaceable bushing in the mounting hole of hammer body, prevents the mounting hole excessive wear of hammer body and cannot continue
It uses；
4. hammer body uses ordinary carbon steel, hammering head uses wear-resistant material, save the cost.
Detailed description of the invention
Fig. 1 is the general structure schematic diagram one of the tup of steel scrap quartering hammer.
Fig. 2 is the structural schematic diagram for hammering head.
Fig. 3 is the structural schematic diagram and its left view of the positioning key installation of the tup of steel scrap quartering hammer.
Specific embodiment
The embodiments of the present invention is described in detail with reference to the accompanying drawing, the example of the embodiment is shown in the accompanying drawings
Out, the embodiment being described with reference to the drawings is exemplary, and is only used for explaining the utility model, and cannot be construed to practical to this
Novel limitation.
A kind of tup of steel scrap quartering hammer of the utility model, including hammer body 1, hammering head 3, positioning key 2, bushing 4, bolt
5, the upper and lower of the application, left and right directions are positioned with the upper and lower of attached drawing 1, left and right directions, are provided in the middle part of the lower end of the hammer body 1
Downwardly projecting trapezoid boss 11, trapezoid boss 11 are the isosceles trapezoidal structure of the narrow lower hem width in top, and described hammers the upper of head 3
End middle part is provided with the trapezoidal groove 32 being adapted with trapezoid boss 11, the waist of 11 isosceles trapezoid of trapezoid boss and bottom edge and ladder
Connected in star 32 forms interference fit.
