Abstract
The utility model discloses a chisel. An axial core (2), made of large hardness of medium carbon steel or high-carbon steel or die steel, is arranged in a chisel rod (1), which is made of soft low carbon steel with fine milling quality. The chisel rod (1) is connected with the axial core (2) by forging and combined into a unity. The core (2) with axial or flat shape, is made of 45 steel or tool steel or die steel. As the core (2) is arranged in the chisel rod (1), when the chisel head is useless for abrasion, only a grinding wheel is used to grind the chisel head for reuse like sharpening a pencil and remelting is unnecessary for the good milling quality of the chisel rod. Therefore, the chisel is convenient to be used and the cost of remelting can be lowered by a large margin.
Description
Technical field
The utility model relates to a kind of hand tools, particularly a kind of chisel that is used for stone carving.
Background technology
Chisel is stone carving industry a kind of instrument commonly used.At present, all chisels are all made with high-quality steel or high-quality iron, and whole engraving tool body all is a commaterial.In the use, in the time of can not re-using when carving the head wearing and tearing, just whole chisel need be melted down machine-shaping again could use, so very trouble wastes time and energy, and uses very inconvenient.
Summary of the invention
The purpose of this utility model overcomes when existing chisel weares and teares exactly need melt down processing, so that uses inconvenient shortcoming, and a kind of do not need to melt down processing, easy to use, long-lived chisel are provided.
The technical solution of the utility model: a kind of chisel, it is carved in the bar has the engraving tool core, carves bar and carve in-core to be integrated outward.
The material of described engraving tool bar is the mild steel of softer excellent cutting performance, and the material of carving core is bigger medium carbon steel of hardness or high-carbon steel, carves bar and carves core and lump together by forging.
The material of described engraving tool core is No. 45 steel or tool steel or mould steel; Described engraving tool core is axle shape or flat; The other end of described engraving tool bar passes through Quenching Treatment.
The beneficial effects of the utility model are: have the engraving tool core owing to carve in the bar, carving core material is bigger medium carbon steel of hardness or high-carbon steel, carving bar material is softer and mild steel excellent cutting performance, when the wearing and tearing of engraving tool head need not re-use, be easy to will carve a reconditioning moulding with emery wheel, simple as sharpening a pencil, just can reuse, and do not need chisel is melted down processing, such chisel is very easy to use, and can significantly reduce the expense of melting down processing again.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the pointed structural representation of carving the chisel of head;
Fig. 2 is the structural representation that flat is carved the chisel of head.
The specific embodiment
Embodiment 1:
In Fig. 1, there is axial hole 3 end of carving bar 1, carving core 2 is the axle shape, insert in the hole 3 of carving bar carving core 2, forge then, make to carve bar 1 and carve core 2 to be linked as an integral body, the material of carving bar 1 is the mild steel of softer excellent cutting performance, the material of carving core 2 is bigger medium carbon steel of hardness or high-carbon steel, can be No. 45 steel or tool steel or mould steel; The other end of carving bar 1 is carried out Quenching Treatment,, be convenient to durable to increase this end hardness.The other end of carving bar 1 is carried out Quenching Treatment,, be convenient to durable to increase this end hardness.
Embodiment 2:
In Fig. 2, there is axial flat groove 3 end of carving bar 1, and carving core 2 is flat, inserts in the flat groove 3 of carving bar 1 carving core 2; Forge then, make to carve bar 1 and carve core 2 to be linked as an integral body, the material of carving bar 1 be the mild steel of softer excellent cutting performance, and the material of engraving tool core 2 is bigger medium carbon steel of hardness or high-carbon steel, can be No. 45 steel or tool steel or mould steel; The other end of carving bar 1 is carried out Quenching Treatment,, be convenient to durable to increase this end hardness.
During use, at first will carve a reconditioning moulding (pointed or flat), just can use then with emery wheel.In the use, in the time of can not re-using when carving the head wearing and tearing, just can carry out reconditioning to carving head with emery wheel, owing to carve core material for being bigger medium carbon steel or the high-carbon steel of hardness, carve bar material and be the mild steel of softer excellent cutting performance, so this reconditioning is very easy to, and is simple as sharpening a pencil, and just can reuse then.So just overcome currently used chisel when carving the head wearing and tearing, chisel need have been melted down again the trouble of processing, very easy to use, and can save a large amount of time and expense.
