Abstract
The utility model relates to an annular knurl, it includes the annular knurl main part, around a plurality of ladder type grooves that the annular knurl main part set up to and the detachable is liftoff installs in a plurality of blades in a plurality of ladder type grooves. A plurality of blades include the bottom respectively, connect the cutter body portion of bottom to and connect the edge of a knife portion of cutter body portion, the distance between the edge of a knife portion of double -phase neighbour's blade of appointing in a plurality of blades is greater than the distance between the bottom, and the angle of pressing from both sides mutually between cutter body portion and the bottom is 85 degrees. Through the detachable blade, reducible cost is multiplicable annular knurl's life still. In addition, can also be according to the embryonic tube of difference, change the blade of different flute profiles, still reduce the man -hour of dismantling whole annular knurl, improve production efficiency.
Description
Technical field
The utility model relates to a kind of metal working technical area, is more particularly a kind of annular knurl in order to process on section bar.
Background technology
Annular knurl utilizes its blade to destroy base tube-surface to mark splicing length, because annular knurl work is frequent, very easily be subject to mechanical damage, and it is serious often to concentrate on wherein several breaks down, thus cause mark disappearance, cause later stage personal identification not out, flow into client and cause immeasurable loss.Change whole annular knurl due to several breaks down, can greater loss be caused, and due to base pipe external diameter size classification many, therefore change profile of tooth will change whole annular knurl, disassembling section is numerous and diverse, waste man-hour.
Utility model content
For deficiency of the prior art, the purpose of this utility model is to provide the dismountable annular knurl of a kind of blade, to replace the annular knurl of original integral type.
The technical scheme that the utility model solves the problems of the technologies described above is, a kind of annular knurl comprises annular knurl main body, around multiple ladder-type troughs that annular knurl main body is arranged, and is installed in multiple blades of multiple ladder-type trough separably.Multiple blade comprises bottom respectively, connect the cutter hub portion of bottom, and connect the knife edge portion in cutter hub portion, the distance between bottom the distance between the knife edge portion of the wantonly two adjacent blades in multiple blade is greater than, and the angle folded between cutter hub portion and bottom is 85 degree.
Preferably, the shape complementarity of the shape of the bottom land of above-mentioned multiple ladder-type trough and the bottom of multiple blade.
Preferably, the cross sectional shape of above-mentioned annular knurl main body on a cross section is circular, and sees it with vertical circular cross section, and blade has the cross sectional shape of isosceles triangle.
The beneficial effects of the utility model are, by dismountable blade, if blade breaks down can change single blade individually, and do not need to change overall annular knurl, reduce cost, also can increase the service life of annular knurl.In addition, because the replacing of blade is convenient, therefore according to different embryonic tubes, the blade of different flute profiles can be changed, also reduce the man-hour of the whole annular knurl of dismounting, enhance productivity.

Description of reference numerals:
Annular knurl main body 10, ladder-type trough 11, blade 12, bottom 13, cutter hub portion 14, knife edge portion 15, distance D1, D2, angle θ.
Detailed description of the invention
Below will with graphic exposure multiple embodiment of the present utility model, as clearly stated, the details in many practices will be explained in the following description.But should be appreciated that, the details in these practices is not applied to limit the utility model.That is, in some embodiments of the present utility model, the details in these practices is non-essential.In addition, for the purpose of simplicity of illustration, some known usual structures and assembly illustrate it by the mode simply illustrated in the drawings.
Fig. 1 is the top view of the annular knurl of the utility model one embodiment, and Fig. 2 is the side view of Fig. 1.Please refer to Fig. 1 and Fig. 2, annular knurl comprises annular knurl main body 10, around multiple ladder-type troughs 11 that annular knurl main body 10 is arranged, and is installed in multiple blades 12 of multiple ladder-type trough 11 separably.Blade 12 comprises bottom 13, connect the cutter hub portion 14 of bottom 13, and connect the knife edge portion 15 in cutter hub portion 14, distance D1 between the knife edge portion 15 of the wantonly two adjacent blades 12 wherein in multiple blade 12 is greater than the distance D2 between bottom 13, and the angle θ folded between cutter hub portion 14 and bottom 13 is 85 degree.
Thus, because blade 12 of the present utility model can be dismountable, single blade 12 can be changed individually if therefore broken down, and not need to change overall annular knurl, reduce cost, also can increase the service life of annular knurl.In addition, because the replacing of blade 12 is convenient, therefore according to different embryonic tubes, the blade 12 of different flute profiles can be changed.By more allowing blade replacement 12, the man-hour of dismantling whole annular knurl can be reduced, enhance productivity.
Please continue to refer to Fig. 1 and Fig. 2, the shape complementarity of the shape of multiple ladder-type trough 11 of the present utility model and the bottom 13 of multiple blade 12.For example, the bottom land shape of ladder-type trough 11 is corresponding with the bottom type shape of blade 12, and blade 12 and ladder-type trough 11 can be agreed with mutually.In addition, as shown in Figure 1, the cross sectional shape of annular knurl main body 10 on a cross section can be circle, and sees it with vertical circular cross section, and blade 12 has the cross sectional shape of isosceles triangle.It can thus be appreciated that blade 12 can be installed in ladder-type trough 11 fast and easily, enhances productivity.
Be described in detail annular knurl provided by the utility model above, the explanation of above embodiment just understands structure of the present utility model for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications.In sum, this description should not be construed as restriction of the present utility model.
