- 摘要:
- 为去除电磁阀阀芯加工后相交小孔处毛刺,以避免毛刺从母材脱落后在阀门内腔形成多余物,通过识别电磁阀阀芯毛刺出现位置及采用常规去毛刺方案的局限性后,提出使用挤压研磨技术方案进行阀芯相交小孔处毛刺去除,同时提出挤压研磨技术中的多余物防控方案,设计并进行正交试验得出有效去除阀芯相交孔处毛刺并避免二次产生的多余物的最优挤压研磨参数。阀芯零件加工后使用挤压研磨技术方案去除阀芯相交孔处毛刺,检查零件相交孔处具备无毛刺、无残留磨料、加工状态一致性好的优点,比常规方案去毛刺的效率提升60以上。挤压研磨技术工艺方案能够有效去除阀芯狭小内腔相交孔处加工后毛刺,并对类似零件的狭小内腔的相交小孔处毛刺去除提供了有效的借鉴方案。
- Abstract:
- In order to remove burrs at the intersecting small holes in the machined solenoid valve spool, so as to avoid the surplus material in the valve cavity after the burrs falling off from the base metal, it was proposed that using the extrusion grinding technology to remove burrs at the intersecting small holes after identifying the burr locations of the solenoid valve spool and learning the limitations of the conventional deburring methods.In addition, the prevention and control scheme of surplus material for extrusion grinding technology was proposed, and the orthogonal experiments was designed and carried out to obtain the optimal parameters in extrusion grinding technology that can effectively remove the burr at the intersecting hole and avoid the secondary generation of surplus material.By removing burrs at the intersecting small holes with the extrusion grinding technology after manufacturing the solenoid valve spool, the intersecting small holes of parts have the advantages of no burrs, no residual abrasives and good consistency of processing state.Compared with the conventional schemes, the deburring efficiency is improved by more than 60 with this method.The extrusion grinding technology can remove the burr at the intersecting small holes effectively and provide an engineering reference scheme for the burr removal at the intersection hole of the narrow inner cavity in other similar parts.
