Abstract
The invention discloses a spiral three-blade forming cutter. The spiral three-blade forming cutter comprises a cutter handle and a cutter head which is connected with the cutter handle, wherein milling blades are arranged on two sides of the end surface of the cutter head; a cooling tank which sinks inwards is arranged on the back side of each milting blade; the spiral three-blade forming cutter also comprises at least two pairs of arc-shaped flow guide tanks which are arranged on the side wall of the cutter head; the gap of each pair of flow guide tanks is narrowed down from the cutter head direction to the cutter handle direction; the flow guide tanks are communicated with the cooling tanks. According to the spiral three-blade forming cutter creatively disclosed by the invention, a cooling structure is mainly and additionally arranged on the conventional cutter; the overall structure of the cutter is not damaged by the cooling structure; the cooling structure can fully cool the milling blades; the spiral three-blade forming cutter is simple in structure, relatively low in cost and easy to popularize and apply.
Description
Technical field
The invention relates to cutter field of tool, particularly points out a kind of three sword spiral forming cuttves.
Background technology
Certain defect is there is in conventional tool in process for cooling, adopt the waste of punching type cooling means to cooling fluid excessive, in adopting, cold hole cooling means easily causes cooling insufficient, adopts the method for surperficial drainage trough also can cause cooling waste that is insufficient and cooling fluid.
Innovation and creation content
The object of the invention is proposition three sword spiral forming cutter, and mainly add cooling structure to traditional cutter, cooling structure does not destroy cutter overall structure, cools fully milling edge, and structure is simple, and cost is lower, is easy to realization and promotes the use of.
The technical scheme realizing the invention object is as follows:
Three sword spiral forming cuttves, comprise handle of a knife, and the cutter head to be connected with handle of a knife, described cutter head end face both sides are provided with milling edge, on rear side of described milling edge, are provided with the cooling bath caved inward, also comprise the arc drainage trough being positioned at cutter head sidewall, it is two right that described drainage trough is at least provided with, and the spacing between often pair of drainage trough is narrowed to handle of a knife direction by cutter head direction, and described drainage trough is communicated with cooling bath.
Further, the diameter of described cutter head and handle of a knife junction is less than cutter head point diameter, and cutter head side is smooth surface.
Further, the diameter of described drainage trough two ends guide groove is less than the diameter of middle guide groove.
Further, described drainage trough is provided with restriction towards one end of cooling bath, and the opening of described restriction is towards cooling bath.
After adopting said structure, the beneficial effect of the invention is: described drainage trough is by cooling fluid Directed cooling groove, cooling bath is positioned at the rear side of cutter head milling edge, the diameter of the drainage trough two ends guide groove is simultaneously less than the diameter of middle guide groove, drainage trough is provided with restriction towards one end of cooling bath, the opening of described restriction is towards cooling bath, and this structure ensures cooling fluid mobility slowly, to ensure sufficient cooling.
Accompanying drawing explanation
Fig. 1 is the structural representation of the invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention is described in further detail.
Three sword spiral forming cuttves, comprise handle of a knife 1, and the cutter head 2 to be connected with handle of a knife 1, described cutter head 2 end face both sides are provided with milling edge 3, on rear side of described milling edge 3, are provided with the cooling bath 4 caved inward, also comprise the arc drainage trough 5 being positioned at cutter head 2 sidewall, it is two right that described drainage trough 5 is at least provided with, and the spacing between often pair of drainage trough 5 is narrowed to handle of a knife 1 direction by cutter head 2 direction, and described drainage trough 5 is communicated with cooling bath 4.
Described drainage trough is communicated with cooling bath, and cooling fluid is transmitted in cooling bath by drainage trough, and for milling edge provides refrigerating function, described drainage trough is distributed in the sidewall of cutter head, also can provide refrigerating function for cutter head, and drainage trough has at least two right, distributes more even.
Described cutter head 2 is less than cutter head point diameter with the diameter of handle of a knife 1 junction, and cutter head side is smooth surface.
According to designing requirement, cutter head, in falling style of the shoe, meets milling angle needs.
The diameter of described drainage trough 5 two ends guide groove is less than the diameter of middle guide groove.Described drainage trough 5 is provided with restriction 6 towards one end of cooling bath, and the opening of described restriction is towards cooling bath.
The structure of above-mentioned drainage trough, ensures the cooling fluid that in drainage trough, buffer memory is certain, cools cutter head, restriction prevents cooling fluid from excessively flowing in cooling bath simultaneously, cause waste.
