Abstract：Taking the recycling and reuse of waste materials in the side wall outer door openings as the carrier， the waste materials synchronization design plan， waste materials relying on its own gravity discharge and collection， stacking， and low-cost flexible automatic cutting waste recycling plan are described in detail. The adoption of this scheme does not affect the guarantee of the raw materials of the benefited parts， and is beneficial to improve the feasibility of using waste materials to reproduce. At the same time， through low-cost automated waste cutting， the cost of waste processing is reduced， and the economic benefits of waste utilization are improved. The application of the universal line-side recycling and separation and shearing workstation overcomes the problem of multiple types of small-batch vehicle reuse， increases the scope of application vehicle types for waste reuse， and achieves obvious economic and environmental benefits.

Key words：side wall outer panel， material utilization rate， waste material reuse， collection tooling， flexible tailoring

为了提高汽车覆盖件的材料利用率，降低材料成本，国内专家对冲压废料的回收利用进行了大量的分析与研究。韦荣发[1]等人研究了废料回收再利用及镶套工艺降低生产成本的方法。梁延焱[2]在冲压工艺的废料处理、模具设计时确保废料顺畅落料等方面详细阐述了冲压生产过程中废料的处理方法。周铁军[3]等人以某侧围外板为研究对象，对侧围外板的废料进行了合理分析设计，实现了9个制件共模开发方案。上述研究均取得了显著成果，但并未涉及开卷落料线废料在线收集、堆垛工装、废料分剪方法的研究。本文以侧围外板门洞废料为例，研究了开卷落料线废料线侧收集、堆垛与低成本柔性化剪裁废料回收再利用方案，并进行实际工程验证，以期为冲压废料的回收与再利用提供参考。……
