Abstract
The utility model provides a cutter for cutting cemented carbide, which comprises a cutter main body, wherein an outer diameter blade and an inner diameter blade which are symmetric are arranged on the two sides of the front part of the cutter main body. The phenomena of separating, breaking and fracturing of a product can be avoided, the production quality can be improved, and the production cost can be lowered.
Description
Technical field
The utility model relates to the hard alloy cutting cutter.
Background technology
Machine-shaping is normally carried out in the processing of carbide alloy at present under the pressed compact state, utilize cutter to cut then.Adding man-hour because the particle hardness ratio of carbide alloy is higher, cutter can produce that cutting edge is not wear-resisting, fragile, the phenomenon of difficult cutting, and owing to be the monolateral edge of a knife, the edge of a knife is also relatively sharper, clamping frequently turns around when processing, can make product produce the limit, collapse the limit, cracking, the not good phenomenon of fineness, reduced product quality, improved production cost.
Summary of the invention
Technical problem to be solved in the utility model is to provide the hard alloy cutting cutter, can prevent that product from producing the limit, collapse the limit, the phenomenon of cracking, improves the quality of products, and reduces production costs.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: the hard alloy cutting cutter, comprise cutter body, and the front part sides of described cutter body is provided with the outer diameter blade and the inner diameter blade of symmetry.
As preferably, described outer diameter blade is provided with anti-limit feed cutting edge and the anti-limit withdrawing cutting edge that collapses of external diameter of collapsing of external diameter, and described external diameter is anti-to collapse limit feed cutting edge and anti-the collapsing of external diameter is provided with the anti-limit master's cutting edge that collapses of external diameter between the withdrawing cutting edge of limit.Prevented that product from collapsing the limit, improved product quality.
As preferably, described inner diameter blade is provided with anti-limit feed cutting edge and the anti-limit withdrawing cutting edge that collapses of internal diameter of collapsing of internal diameter, and described internal diameter is anti-to collapse limit feed cutting edge and anti-the collapsing of internal diameter is provided with the anti-limit master's cutting edge that collapses of internal diameter between the withdrawing cutting edge of limit.Prevented that product from collapsing the limit, improved product quality.
As preferably, the front portion of described cutter body is provided with anti-breakhead.Avoid blade impaired.
As preferably, the front part sides of described cutter body also is provided with the powder discharge launder.
As preferably, the bottom of described outer diameter blade and inner diameter blade is equipped with shockproof cushion block.Prevent that blade is owing to vibrations influence cutting.
Beneficial effect:
The utility model adopts technique scheme that the hard alloy cutting cutter is provided, and has prevented that product from producing the limit, collapse the limit, the phenomenon of cracking, has improved product quality, has reduced production cost.
