The common plate hammer has short service life and large consumption, a large amount of spare parts are required to be reserved to maintain normal production, and the whole replacement cost is high after the striking face is abraded.
The technical problems existing in the prior art are as follows: firstly, the plate hammer made of a material with high hardness is easy to cause integral brittle failure, while the plate hammer made of a material with good toughness causes low hardness of a striking face, rapid abrasion, incapability of having good abrasion resistance and toughness, short service life and frequent replacement, so that the production cost is increased, and the labor intensity of workers is increased; secondly, due to the impact nonuniformity of the materials on the striking surface of the plate hammer, the abrasion degree of the striking surface is inconsistent, and under the condition that the local part is seriously abraded and other adjacent parts are slightly abraded, the whole plate hammer needs to be replaced, so that the waste is serious and the use cost is high; the hammer is of a plane structure, 360-degree rotation work is performed in the production process, materials fall vertically, the striking surface of the hammer is often in an uneven stress state, no buffer exists, and abrasion is serious.
How to solve the above problems is a matter of urgency for those skilled in the art to work.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a two-sided board hammer convenient to change striking piece solves following technical problem: firstly, how to achieve the purpose that the plate hammer has good wear resistance and toughness at the same time; how to achieve local abrasion of the striking surface of the plate hammer and change the striking surface locally, thereby reducing the use cost; and thirdly, how to buffer the materials when the materials are contacted with the striking surface, and the phenomenon of too much impact stress concentration can not occur.
The utility model adopts the following technical scheme:
the utility model provides a two-sided board hammer convenient to change strikes piece which characterized in that: comprises a main body, a wear-resistant striking block, a baffle plate, a gasket and a fastening bolt.
The main part include hammer block, installation handle, screw hole and forked tail recess.
The wear-resistant striking block comprises a dovetail convex rib and an arc striking body.
The wear-resistant striking block is matched with the dovetail groove through the dovetail convex edge, and the wear-resistant striking block is connected with the main body.
The baffle is provided with a through hole.
The fastening bolt penetrates through the through holes of the washer and the baffle plate and then is matched with the threaded hole in the main body, and the baffle plate is installed at two ends of the hammer body.
And wear-resistant striking blocks are arranged on the two striking surfaces of the main body.
The main part both ends all install the baffle, every baffle is fixed by two fastening bolt.
The striking surface of the abrasion-resistant striking block is arc-shaped.
The utility model discloses following beneficial technological effect has:
1) the utility model discloses the hammer block comprises carbon steel or low alloy steel, and the face of striking then is formed by the concatenation of wear-resisting striking piece, has good wearability and toughness concurrently.
2) Because the striking face is formed by the concatenation of the less wear-resisting striking piece of polylith striking area, can adapt to the different operating modes of plate hammer minizone degree of wear, under the condition of minizone wearing and tearing, only can solve the serious problem of local wear through changing one or several wear-resisting striking pieces, avoid changing the extravagant problem that whole plate hammer brought.
3) The plate hammer is arc-shaped with the material contact surface, the material can be buffered when contacting with the striking surface, the phenomenon of too much impact stress concentration can not occur, the service life of the wear-resistant striking block is effectively prolonged, and the service cycle of the whole plate hammer is further prolonged.
