The thread processing cutter is characterized in that the tooth top of fine cutting tooth is arc-linear tooth-shaped, and is matched with the form of threads; the tooth top of the coarse cutting tooth is arc-linear tooth-shaped, and is smaller than the form of the threads; the tooth top difference of the coarse cutting tooth relative to the fine cutting tooth is 0.075-0.125 mm; the edge-sharpening angle of the cutter body is 3 degrees; the cutting edge radian R of the fine cutting tooth and the coarse cutting tooth is 0.8 mm; the cutting edge height of the fine cutting tooth and the coarse cutting tooth is 2.85-3.15 mm. According to the thread processing cutter, a free cutting manner is adopted, the cutting force is smaller, the loads among the teeth on the cutter are distributed uniformly, the chip removing and cutting capability is high, the service life of the cutter can be prolonged, and the production efficiency of the cutter can be improved.
Description
Technical field:
The utility model relates to the process tool field, particularly a kind of threading tool.
Background technology:
In recent years, along with the development of petroleum pipeline processing industry, the service life of double thread cutter and the requirement of surface quality thereof are more and more higher.Machining screw is to have cut on numerically controlled lathe, the cutter used in the market is owing to adopting non-free style cutting way, be difficult to solve the load problem pockety between each tooth, gently cause product low service life, heavy easily cause and forge a knife, not only cause tool damage, cause greatly reduce cutter life, thereby reduction production efficiency, also likely damage processing work and cause product rejection, thereby the cutter used in the market can't meet the development need of petroleum pipeline processing industry.
Summary of the invention:
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of cutting force less, and chip removal chip breaking ability is high, the threading tool of long service life.This threading tool has adopted the free style cutting way, and cutting force is less, on cutter between each tooth load be evenly distributed, chip removal chip breaking ability is high, reaches the purpose that improves cutter life and production efficiency.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of threading tool, comprise cutter hub, described cutter hub side is provided with working face, the center of described cutter hub is provided with installing hole, and described working face is provided with the cutting teeth group that comprises roughing tooth and finishing tooth, and described finishing tooth tooth top is circular arc-straight line profile of tooth, and be complementary with the tooth form of described screw thread, described roughing tooth tooth top is circular arc-straight line profile of tooth, and is less than the tooth form of described screw thread
Described roughing tooth is poor with respect to the tooth top of described finishing tooth is 0.1 ± 0.025mm, and the angle of putting the first edge on a knife or a pair of scissors of described cutter hub is 3 °, and the cutting edge radian of described finishing tooth and roughing tooth is R=0.8mm, and the cutting edge height of described finishing tooth and roughing tooth is 3 ± 0.15mm.
Preferably, the quantity of described roughing tooth and described finishing tooth is respectively 1.
Preferably, form the cutting edge groove between described roughing tooth and finishing tooth.
Preferably, described cutter hub is the triangle cutter hub.
Preferably, described working face has two.
Preferably, described installing hole is manhole.
Technique scheme has following beneficial effect: threading tool cutting way of the present utility model is the free style cutting way, and has adopted rational tooth top poor, has solved the load problem pockety between each tooth.In when cutting, because the profile of tooth of roughing tooth is less than form of thread, not the holotype cutting, so cutting resistance is less than the cutting force of holotype cutting during cutting, although finishing tooth is the holotype cutting, the chipping allowance while cutting is very little, cutting force is less.And, the cutting edge radian of put the first edge on a knife or a pair of scissors angle and roughing tooth and the finishing tooth of this threading tool by improving cutter hub, its cutting edge groove has guaranteed timely chip breaking, does not roll up bits, will surface of the work not caused to damage like this, thereby improves the surface smoothness of product.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, below with the specific embodiment of the present utility model and coordinate accompanying drawing to be elaborated to this patent.
The accompanying drawing explanation:
Fig. 1 is the structural representation of the utility model threading tool.
Fig. 2 is the schematic diagram of the cutting teeth group of threading tool shown in Fig. 1.
Fig. 3 is finishing tooth and the roughing tooth cutting edge schematic diagram of threading tool shown in Fig. 1.
The specific embodiment:
As shown in Figure 1, Figure 2 and Figure 3, a kind of threading tool of the present utility model, comprise cutter hub 1, described cutter hub side is provided with working face 2, and the center of described cutter hub 1 is provided with installing hole 3, and described working face 2 is provided with the cutting teeth group that comprises roughing tooth 22 and finishing tooth 21, described finishing tooth 21 tooth tops are circular arc-straight line profile of tooth, and be complementary with the tooth form of described screw thread, described roughing tooth 22 tooth tops are circular arc-straight line profile of tooth, and are less than the tooth form of described screw thread.Described roughing tooth 22 is 0.1 ± 0.025mm with respect to the poor D of the tooth top of described finishing tooth 21, the angle A of putting the first edge on a knife or a pair of scissors of described cutter hub 1 is 3 °, the cutting edge radian B of described finishing tooth 21 and roughing tooth 22 is R=0.8mm, and the cutting edge height C of described finishing tooth 21 and roughing tooth 22 is 3 ± 0.15mm.In the present embodiment, the quantity of described roughing tooth 22 and described finishing tooth 21 is respectively 1.
This threading tool adopts the free style cutting way, and the poor D of tooth top is designed to 0.1 ± 0.025mm, and between each tooth, load is evenly distributed.In when cutting, because the profile of tooth of roughing tooth 22 is less than form of thread, not the holotype cutting, so cutting resistance is less than the cutting force of holotype cutting during cutting, although finishing tooth 21 is holotype cuttings, the chipping allowance while cutting is very little, cutting force is less.
The cutting edge radian B of described finishing tooth 21 and roughing tooth 22 is made as R=0.8mm, and the cutting edge height C of described finishing tooth 21 and roughing tooth 22 is 3 ± 0.15mm, and the angle of putting the first edge on a knife or a pair of scissors of cutter hub is made as 3 °.The setting of these parameters, improved the chip removal chip breaking ability of cutting edge groove, thereby improved the fineness of product surface.
In the present embodiment, cutter hub 1 is made as the triangle cutter hub, and cutter hub intensity is good, easily installs, and also can be set to other shapes according to concrete condition.
In addition, the both sides of cutter hub 1 respectively arrange a working face 2, after a working face damages, can rotate cutter hub 1 along installing hole, can use another working face.Installing hole 3 is set to manhole, for by Cutting tool installation manner at knife rest, cutter can rotate along it.
The above is explained in detail embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also under the prerequisite that does not break away from the utility model aim, make a variety of changes.
