Abstract
The utility model discloses an inner burr blade. The inner burr blade comprises a blade body, wherein a blade edge is arranged on the end portion of the blade body, and the size of an included angle between the surface of the blade edge and the horizontal plane is 35.5 degrees. The inner burr blade is simple in structure, easy to manufacture, and capable of effectively improving the abrasion resistance and impact resistance of the blade edge, and thus the service life of the inner burr blade is prolonged.
Description
Technical field
The utility model relates to a kind of lining inner burr removing apparatus, particularly relates to a kind of inner burr blade.
Background technology
In the ratio-frequency welded tube production process, by the welding extrusion process, the oxide between weld seam is squeezed out the formation burr, pass through In-line inner-deburring system, the inner burr of heat is removed, and after the assurance scraping, the burr smooth transition is to mother metal, and residual inner burr height meets the requirements of the customers.
At present, generally use the inner burr blade as lining inner burr removing apparatus, still, existing inner burr blade end edge surface and horizontal plane angle are 42 °, cause the cutting edge thickness low LCL, cause tool edge wear-proof and anti-impact force undesirable, and blade is too short service life.
The utility model content
The purpose of this utility model just is to provide a kind of inner burr blade, can effectively improve wearability and the anti-impact force of cutting edge, promotes blade service life, thereby solves above-mentioned the deficiencies in the prior art part fully.
The purpose of this utility model realizes by following technical proposals:
A kind of inner burr blade comprises vane body, and there is cutting edge the vane body end, the angle of described edge surface and horizontal plane be 35 ° 30 '.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, easily make, and can effectively improve wearability and the anti-impact force of cutting edge, promote blade service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As shown in Figure 1, a kind of inner burr blade comprises vane body 1, and there is cutting edge 2 vane body 1 end, the angle α of described cutting edge 2 surfaces and horizontal plane be 35 ° 30 '.
The utility model has reduced the angle α between cutting edge 2 surfaces and horizontal plane, thereby has increased cutting edge 2 thickness, makes the wearability of cutting edge 2 and anti-impact force improve, and then has promoted blade service life.And this inner burr blade is cheap for manufacturing cost, uses this inner burr blade to replace the inner burr blade of import greatly to reduce costs.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
