            減少模具鋼加工缺陷的幾小方法

            模具加工即指成型和制坯工具的加工,此外還包括剪切模和模切模具,在模具加工的時候,有時候會出現缺陷,下面小編就來說一下減少模具加工缺陷的幾小方法。
              Mold processing refers to the processing of forming and blank making tools. In addition, it also includes shear mold and die-cutting mold. When the mold is processed, sometimes there will be defects. The following small series is about several small methods to reduce mold processing defects.
              一:合理使用冷卻潤滑液,發揮冷卻、洗滌、潤滑的三大作用,保持冷卻潤滑清潔,從而控制磨削熱在允許范圍內,以防止工件熱變形。改善磨削時的冷卻條件,如采用浸油砂輪或內冷卻砂輪等措施。將切削液引入砂輪的,切削液可直接進入磨削區,發揮有效的冷卻作用,防止工件表面燒傷。
              1: Reasonable use of cooling and lubricating fluid, play the three major roles of cooling, washing and lubrication, keep the cooling and lubrication clean, so as to control the grinding heat within the allowable range, so as to prevent the thermal deformation of the workpiece. Improve the cooling conditions during grinding, such as using oil immersed grinding wheel or internal cooling grinding wheel. When the cutting fluid is introduced into the center of the grinding wheel, the cutting fluid can directly enter into the grinding area to play an effective cooling role and prevent the surface burn of the workpiece.

              二:合理選擇磨削用量,采用徑向進給量較小的精磨方法甚至精細磨削。如適當減少徑向進給量及砂輪速度、增大軸向進給量,使砂輪與工件接觸面積減少,散熱條件得到改善,從而有效地控制表層溫度的提高。
              2: In order to select the grinding parameters reasonably, the fine grinding method with smaller radial feed rate and even fine grinding is adopted. If the radial feed rate and grinding wheel speed are properly reduced and the axial feed rate is increased, the contact area between the grinding wheel and the workpiece is reduced, and the heat dissipation condition is improved, so as to effectively control the increase of surface temperature.
              三:合理選擇和修整砂輪,采用白剛玉的砂輪較好,它的性能硬而脆,且易產生新的切削刃,因此切削力小,磨削熱較小,在粒度上使用中等粒度,如46~60目較好,在砂輪硬度上采用中軟和軟(ZR1、ZR2和R1、R2),即粗粒度、低硬度的砂輪,自勵性好可降低切削熱。
              3: Reasonable selection and dressing of grinding wheel, white corundum grinding wheel is better, its performance is hard and brittle, and easy to produce new cutting edge, therefore, the cutting force is small, grinding heat is small, medium grain size is better, such as 46-60 mesh is better, in the wheel hardness, medium soft and soft (ZR1, Zr2 and R1, R2), that is, coarse-grained, low hardness grinding wheel, good self excitation, can reduce cutting heat.
              以上是關于減少模具加工缺陷的三方法的介紹,希望能夠幫到大家!
              The above is about reducing the mold processing defects of the three methods, I hope to help you!
