Abstract
The utility model relates to an external thread cutter. The external thread cutter is characterized by comprising a cutter handle and a welding cutter bit, wherein the welding cutter bit is arranged at one end of the cutter handle; the welding cutter bit is provided with a blade, the blade comprises a first blade surface, a second blade surface, a transition surface and a third blade surface, the first blade surface and the second blade surface are connected through a first end face, the second blade surface is joined with the transition surface, the transition surface and the third blade surface are connected through a second end face, and the distance between the first end face and the cutter handle is larger than the distance between the second end face and the cutter handle. According to the non-standard external thread cutter, thread taper is formed through one-time machining, a traditional machining mode that firstly taper is turned and then threads are machined is changed, blade welding can be coped several times, and cost of the cutter is saved.
Description
Technical field
The utility model 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 " " 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.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of nonstandard external screw thread cutter is provided, and 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 utility model 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, connect by the first end face, described the second blade face is connected mutually with described transition face, between described transition face, the 3rd blade face by 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.
The utility model beneficial effect is: nonstandard external screw thread cutter of the present utility model, 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 the utility model external screw thread cutter;
Fig. 2 is the local enlarged diagram of the blade of the utility model external screw thread cutter.
In figure: 10, handle of a knife, 20, welding cutter head, 21, blade, 211, the first blade face,
213, the second blade face, 215, transition face, 217, the 3rd blade face, 219, the first end face, 220, the second end face.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Coordinate with reference to shown in Fig. 1 and Fig. 2, in the utility model 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, connect by the first end face 219, described the second blade face 213 is connected mutually with described transition face 215, described transition face 215, between the 3rd blade face 217, connect by the second end face 220, 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 utility model preferred embodiment, 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, the utility model beneficial effect is: nonstandard external screw thread cutter of the present utility model, 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 preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
