Abstract
The utility model discloses a board hammer of an impact crusher, which comprises an elongated hammer body and a plurality of connection holes arranged on a hammering face of the elongated hammer body along a longitudinal direction. The hammering face of the hammer body is also provided with a plurality of parting bars, which are mutually parallel and are vertical to a longitudinal symmetrical line, and a wear-resisting body is welded between every two parting bars. The parting bars arranged on the hammering face of the hammer body are convenient for wear-resisting welding rods to be welded between every two parting bars in an overlaid way so that the welding firmness is enhanced, continuous overlaying welding can be carried out after the welding rods are worn, and thus, the service life of the board hammer is greatly prolonged.
Description
Technical field
The utility model relates to a kind of bar that is used for impact breaker.
Background technology
Impact breaker is a kind of muck equipment of novel efficient, is characterized in that volume is little, simple structure, and the ratio of reduction is big, less energy consumption, production capacity is big, and product granularity is even, and muck effect selectively, is rising equipment.But it is easy to wear especially that the shortcoming of its maximum is a bar, the bar material adopts potassium steel ZGMnl3 more at present, but in, under the low impact wear situation, it impacts the transformation hardening ability and can not give full play to, it is lower to show as wearability, and service life is shorter, especially broken hard ore, it is even more serious to wear and tear, and needs often to change.
Summary of the invention
The utility model provides a kind of impact breaker bar at the deficiency that prior art exists, and its scope of attack is welded with high-abrasive material, to prolong the service life of tup.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of impact breaker bar, comprise several connecting holes that the strip hammer body and the scope of attack thereof longitudinally are provided with, also be provided with the parting bead that several are parallel to each other on the described hammer body scope of attack, and vertical with vertical line of symmetry, be welded with wear body between described two parting beads.
Further, the height of described parting bead is between 10～20mm, and width is between 20～30mm.
Further, the quantity of described parting bead is between 6～12.
Further, the thickness of described wear body equates with the height of parting bead.
The beneficial effects of the utility model are and since be provided with on the hammer body scope of attack several parting beads be convenient between the build-up wear-resistant welding rod, increase the firm welding degree, and built-up welding continuously after the wearing and tearing, prolong bar service life greatly.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the front view of the utility model impact breaker bar.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of impact breaker bar, comprise several connecting holes 11 that the strip hammer body 1 and the scope of attack thereof longitudinally are provided with, also be provided with several parting beads that is parallel to each other 12 on hammer body 1 scope of attack, and it is vertical with vertical line of symmetry, be welded with wear body 2 between described two parting beads 12, described wear body 2 is formed by the wear resistance electrode built-up welding.The height of described parting bead 12 is between 10～20mm, and width is between 20～30mm.According to bar specification size, the quantity of general parting bead 12 is between 6～12.Design parting bead 12 on the bar scope of attack, can increase the firmness of welding.Fill up high-abrasive material between the general parting bead 12, promptly the thickness of wear body 2 equates with the height of parting bead 12.Parting bead 12 is cast as one with hammer body 1.
Connecting hole 11 on the described hammer body 1 is used for being connected with hammer seat bolt on the impact breaker rotor block.Wear body 2 may wear to a certain degree, can continue the build-up wear-resistant material thereon, thereby prolongs the service life of bar greatly.
