Abstract
The invention relates to an externally-threaded tool. The externally-threaded tool is characterized in that the externally-threaded tool comprises a tool handle and a welding tool head arranged at one end of the tool handle and provided with a blade. The blade comprises a first blade face, a second blade face, a transition face and a third blade face, wherein the first blade face is connected with the second blade face through a first end surface, the second blade face is connected with the transition face, the transition face is connected with the third blade face through a second end surface, and the distance between the first end surface and the tool handle is larger than the distance between the second end surface and the tool handle. Because thread taper once machining forming is achieved, the non-standard externally-threaded tool changes the traditional machining mode of taper turning before thread machining; the blade can be polished several times after being welded, and tool cost is saved.
Description
Technical field
The present invention relates to a kind of hardware and cutting-tools technical field, particularly a kind of external screw thread cutter.
Background technology
Screw cutter is a kind of common machining tool.In prior art, the processing mode of traditional external screw thread cutter is: first " turn taper " be " machining screw " afterwards, and thread taper is difficult to realize time processing moulding, manufactures efficiency not high, is unfavorable for improving production capacity; On the other hand, also have much room for improvement the service life of traditional external screw thread cutter, and manufacturing cost also needs to be reduced.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, a kind of nonstandard external screw thread cutter is provided, thread taper can time processing moulding, to improve the low manufacture efficiency of traditional processing mode of machining screw after first turn taper.
For achieving the above object, the present invention is by the following technical solutions:
A kind of external screw thread cutter, comprise handle of a knife, be arranged at the welding cutter head of handle of a knife one end, described welding cutter head possesses blade, described blade comprises the first blade face, the second blade face, transition face and the 3rd blade face, between described the first blade face, the second blade face, by the first end face, connect, described the second blade face is connected mutually with described transition face, between described transition face, the 3rd blade face, by the second end face, connect, described the first end face with the distance of described handle of a knife than the distance of described the second end face and described handle of a knife.
Further, described the first end face is arc.
Further, described the second end face is plane.
Further, described the first blade face and described the second blade face angle are between 2 ° to 55 °.
Further, described the first blade face and described the second blade face angle are 30 °.
Further, the width of described the second end face is between 0.1 to 0.5mm.
Further, the width of described the second end face is 0.3mm.
Further, the length of described welding cutter head is greater than three times of thickness of described welding cutter head.
Beneficial effect of the present invention is: nonstandard external screw thread cutter of the present invention, the moulding of thread taper time processing, has solved traditional processing mode of machining screw after first turn taper, blade welding can reconditioning several times, save the cost of charp tool.
Accompanying drawing explanation
Fig. 1 is the structural representation of external screw thread cutter of the present invention;
Fig. 2 is the local enlarged diagram of the blade of external screw thread cutter of the present invention.
In figure: 10, handle of a knife, 20, welding cutter head, 21, blade, the 211, first blade face,
213, the second blade face, 215, transition face, the 217, the 3rd blade face, the 219, first end face,
220, the second end face.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Cooperation is with reference to shown in Fig. 1 and Fig. 2, in the present invention's one specific embodiment, a kind of external screw thread cutter, comprise handle of a knife 10, be arranged at the welding cutter head 20 of handle of a knife 10 one end, described welding cutter head 20 possesses blade 21, described blade 21 comprises the first blade face 211, the second blade face 213, transition face 215 and the 3rd blade face 217, described the first blade face 211, between the second blade face 213, by the first end face 219, connect, described the second blade face 213 is connected mutually with described transition face 215, described transition face 215, between the 3rd blade face 217, by the second end face 220, connect, the distance of described the first end face 219 and described handle of a knife 10 is the distance with described handle of a knife 10 than described the second end face 220.Wherein, welding cutter head 20 is fixed on an end of described handle of a knife by the mode of welding, and is partial to the lower position of described handle of a knife one side, and further, the length of described welding cutter head 20 is greater than three times of thickness of described welding cutter head 20.Wherein, in the preferred embodiment of the invention, described the first end face 219 is arc, and described the second end face 220 is plane.By first, second end face is designed to as above structure, can realize one-shot forming thread taper.
In the present embodiment, described the first blade face 211 and described the second blade face 213 angles are between 2 ° to 55 °, and further, described the first blade face 211 is 30 ° with described the second blade face 213 angles.Further, the width of described the second end face 220 is between 0.1 to 0.5mm, and further, the width of described the second end face 220 is 0.3mm.
In sum, beneficial effect of the present invention is: nonstandard external screw thread cutter of the present invention, the moulding of thread taper time processing, has solved traditional processing mode of machining screw after first turn taper, blade welding can reconditioning several times, save the cost of charp tool.
The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
