Abstract
The utility model discloses a quartering hammer head. The quartering hammer head comprises a hammer head, a hammer handle and a hammer body, wherein the hammer head and the hammer body are fixed together through the hammer handle; and a fixed through hole is formed in the hammer head. The quench tempering structure on the working part of the hammer body is tempered martensite + dispersion carbide + retained austenite, and the quench tempering structure on the hammer handle is pearlite + dispersion carbide, with a high comprehensive wear-resisting property; the service life of the hammer is 2-3 times of the traditional high manganese steel and 3-4 times of forging steel (65Mn); besides, the hammer head and the hammer handle are fixed through a bolt, so that the disassembly is convenient, the replacement time is reduced, and the working efficiency is improved; and the bolt and the nut arranged in the groove of the hammer head have the function of protection.
Description
Technical field
The utility model relates to a kind of breaking device, is specially a kind of cracking hammer head.
Background technology
Tup is the important process parts on disintegrating machine, and in machine work, tup can bear stronger impulsive force and frictional force, and tup easily ruptures under high-frequency working environment, and changing tup needs spended time and artificial, affects operating efficiency.
Utility model content
The purpose of this utility model is to provide a kind of changeing conveniently, the not cracking hammer head of easy fracture.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of cracking hammer head, include tup and hammer strength, it is characterized in that: it is inner that described hammer handle inserts tup, and hammer handle insertion portion and tup partly have the through hole of concentricity axle, by screw bolt and nut, hammer handle and tup are fixed together, on hammer handle, have a fixing through hole.
Described a kind of cracking hammer head, is characterized in that: described tup working portion is outside sweep arc.
Described a kind of cracking hammer head, is characterized in that: described screw bolt and nut is in tup groove.
The utility model has the advantages that:
Hammer body working position Q-tempering is organized as tempered martensite+diffusion carbide+retained austenite, and hammer handle position Q-tempering is organized as pearlite+diffusion carbide, has higher comprehensive anti-wear performance; Be 2 ~ 3 times of traditional potassium steel its service life, is 3 ~ 4 times of forge steel (65Mn).And tup, hammer handle are bolted and change conveniently, have reduced the replacing time, have improved operating efficiency, and screw bolt and nut, in tup groove, has played protective effect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1.A kind of cracking hammer head, include tup 4 and hammer handle 3, described hammer handle 3 inserts tup 4 inside, and hammer handle 3 insertion portions and tup 4 have the through hole 1 of concentricity axle, by screw bolt and nut, hammer handle 3 and tup 4 are fixed together, on hammer handle 3, have a fixing through hole 2.
Described tup working portion is outside sweep arc.
Described a kind of cracking hammer head, described screw bolt and nut is in tup groove.
Claims (3)
1. a cracking hammer head, include tup and hammer neck, it is characterized in that: it is inner that described hammer neck inserts tup, hammer neck insertion portion and tup partly have the through hole of concentricity axle, by screw bolt and nut, say that hammer neck and tup are fixed together, on hammer neck, have a fixing through hole.
2. a kind of cracking hammer head according to claim 1, is characterized in that: described tup working portion is outside sweep arc.
