Description
技术领域 technical field
本发明涉及金属切削中的切屑刀具领域，尤其涉及一种具有非等限制接触长度的新型限制接触外圆车刀。 The invention relates to the field of cutting tools in metal cutting, in particular to a novel limited contact outer circle turning tool with unequal limited contact lengths.
背景技术 Background technique
早在80年代，限制接触刀具因其具有良好的切削性能：减少主切削力15%~25%，减少进给力50%~60%，降低切削温度100℃左右等，在金属切削领域引起了众多研究者的兴趣。人们发现限制接触长度l c 减少到一定值时，限制接触刀具都能有效减少切削力，降低切削温度；然而，当l c 进一步减少时，由于刀尖的强度低，刀具发生严重的磨损，使切削力突然猛增，刀具寿命变短。另外，传统的限制接触刀具，大都局限于矩形形状的限制接触面，即等限制接触长度。 As early as the 1980s, because of its good cutting performance, the limited contact tool has caused a lot of attention in the field of metal cutting, such as reducing the main cutting force by 15%~25%, reducing the feed force by 50%~60%, and reducing the cutting temperature by about 100°C. researcher's interest. It is found that when the limited contact length lc is reduced to a certain value, the limited contact tool can effectively reduce the cutting force and reduce the cutting temperature; however , when lc is further reduced, the tool will be severely worn due to the low strength of the tool tip, making the Cutting forces suddenly increase and tool life shortens. In addition, most of the traditional limited contact tools are limited to the rectangular limited contact surface, that is, the limited contact length.
本发明的新型限制接触刀具，在前刀面上具有非等限制接触长度。它同样具备大幅度减少切削力，降低切削温度的功能。与具有等限制接触长度的传统限制接触刀具相比，此新型限制接触刀具，由于具有非等限制接触长度，它能控制切屑的卷曲方向，可以避免切屑刮花已加工表面，从而提高已加工表面的表面质量。另外，对于V字型等内凹形状的限制接触面，因其主切削刃的强度相对高，而且内凹形状利于切削液接近切削区，进一步降低切削温度，因而使得刀具具有更长的使用寿命。 The novel limited contact tool of the present invention has unequal limited contact lengths on the rake face. It also has the function of greatly reducing cutting force and cutting temperature. Compared with the traditional limited contact tool with equal limited contact length, this new limited contact tool can control the curling direction of chips due to its non-equal limited contact length, which can prevent chips from scratching the machined surface, thereby improving the machined surface. surface quality. In addition, for the limited contact surface of the V-shaped concave shape, because the strength of the main cutting edge is relatively high, and the concave shape facilitates the cutting fluid to approach the cutting area, further reducing the cutting temperature, so that the tool has a longer service life .
先进的粉末冶金成型技术的出现，使得制备具有复杂前刀面形状的刀具成为可能。因此，本发明的新型限制接触外圆车刀可以采用该技术实现大批量的生产。 The emergence of advanced powder metallurgy forming technology has made it possible to prepare tools with complex rake face shapes. Therefore, the novel limited-contact cylindrical turning tool of the present invention can adopt this technology to realize mass production.
