濾網(wǎng)沖壓成形工藝及模具設計
摘要：本設計進行了落料拉伸復合模和沖孔模具的設計。文中簡要概述了沖壓模具目前的發(fā)展狀況和趨勢。對產品進行了詳細工藝分析和工藝方案的確定。按照沖壓模具設計的一般步驟，計算并設計了本套模具上的主要零部件，如：凸模、凹模、凸模固定板、墊板、凹模固定板、卸料板、導尺、擋料銷、導正銷等。模架采用標準模架，選用了合適的沖壓設備。設計中對工作零件和壓力機規(guī)格均進行了必要的校核計算。模具的沖孔和落料凸模分別用不同的固定板固定，便于調整間隙；落料凹模則采用整體固定板固定。如此設計出的結構可確保模具工作運行可靠和沖壓產品大批量生產的要求。

Mesh stamping forming technology and die design
Abstract: The design of the loading material, tensile modulus and single composite processes Piercing Die Design. This paper briefly outlined the Stamping Die current development status and trends. Identify the product of a detailed analysis and the process. Stamping die design in accordance with the general steps to calculate and design the sets on the main mold parts, such as: Terrace die、Cavity die、Punch-holder、Dunn age、Die holder、Stripper、 Jig、Pin stop、Pilot and so on. Die-standard model planes, to choose a suitable stamping equipment. Design work on the parts and specifications will press for the necessary checking calculation. Punch and Die blanking punch were different plate fixed to facilitate adjustment gap; Punch and Die blanking die is used overall fixed plate. Blanking punch contents is a derivative sales, and guarantee the work piece and the shape of the holes in the relative position accurately, improve processing accuracy. So the structure is designed to ensure reliable operation of die stamping products and the requirements of large-scale production.
