模具設計制作的要求
模具設計制作的要求是:尺寸精確、表面光潔;結構合理、生產效率高、易于自動化;制造容易、壽命高、成本低;設計符合工藝需要,經濟合理。
The requirements of die design and manufacture are: precise size, smooth surface; reasonable structure, high production efficiency, easy automation; easy manufacturing, high life, low cost; design meets the needs of technology, economic and reasonable.
模具結構設計和參數選擇須考慮剛性、導向性、卸料機構、定位方法、間隙大小等因素。模具上的易損件應容易更換。對于塑料模和壓鑄模,還需要考慮合理的澆注系統、熔融塑料或金屬流動狀態、進入型腔的位置與方向。為了提高生產率、減少流道澆注損失,可采用多型腔模具,在一模具內能同時完成多個相同或不同的制品。在大批量生產中應采用高效率、高精度、高壽命的模具。
The factors such as rigidity, directivity, unloading mechanism, positioning method and clearance size www.kelinbaojie.cn www.dzhlzj.com www.aohailaowu.com www.fanguangmo51.com www.beijingqima.cn www.tianchengwuzi.com.cn4000312797should be taken into account in die structure design and parameter selection. The vulnerable parts on the die should be easily replaced. For plastic and die casting moulds, reasonable pouring system, flow state of molten plastics or metals, and the position and direction of entering the cavity should also be considered. In order to improve productivity and reduce runner pouring loss, a multi-cavity die can be used to complete multiple identical or different products simultaneously in one die. In mass production, high efficiency, high precision and long life die should be adopted.
沖壓模應采用多工位級進模,可采用硬質合金鑲塊級進模,以提高壽命。在小批量生產和新產品試制中,應采用結構簡單、制造快、成本低的簡易模具,如組合沖模、薄板沖模、聚氨酯橡膠模、低熔點合金模、鋅合金模、超塑性合金模等。模具已開始采用計算機輔助設計(CAD),即通過以計算機為中心的一整套系統對模具進行最優化設計。這是模具設計的發展方向。
Stamping die should adopt multi-position progressive die and carbide insert progressive die to improve service life. In small batch production and trial production of new products, simple dies with simple structure, fast manufacturing and low cost should be adopted, such as combined die, sheet die, polyurethane rubber die, low melting point alloy die, zinc alloy die, superplastic alloy die, etc. Computer aided design (CAD) has been used in die design, that is, the optimal design of die has been carried out through a computer-centered system. This is the development direction of die design.
模具制造按結構特點,分為平面的沖裁模和具有空間的型腔模。沖裁模利用凸模與凹模的尺寸精確配合,有的甚至是無間隙配合。其他鍛模如冷擠壓模、壓鑄模、粉末冶金模、塑料模、橡膠模等都屬于型腔模,用于成形立體形狀的工件。型腔模在長、寬、高 3個方向都有尺寸要求,形狀復雜,制造困難。模具生產一般為單件、小批生產,制造要求嚴格、精確,多采用精密的加工設備和測量裝置。
According to the structure characteristics, die manufacturing can be divided into planar blanking die and cavity die with space. Punching dies are precisely matched with the dimensions of punches and dies, and some even have no clearance matching. Other forging dies, such as cold extrusion dies, die casting dies, powder metallurgy dies, plastic dies, rubber dies and so on, belong to cavity dies and are used to form workpieces with three-dimensional shapes. Cavity die has dimension requirements in three directions of length, width and height, and its shape is complex and difficult to manufacture. Mould production is generally single-unit and small-batch production, which requires strict and accurate manufacturing. Precision processing equipment and measuring devices are mostly used.
平面沖裁模可用電火花加工初成形,再用成形磨削,坐標磨削等方法進一步提高精度。成形磨削可用光學投影曲線磨床,或帶有縮仿、修打砂輪機構的平面磨床,也可在精密平面磨床上采用專用成形磨削工具磨削。坐標磨床可用于模具的精密定位,以保證精密孔徑和孔距。也可用計算機數控(CNC)連續軌跡坐標磨床磨削任何曲線形狀的凸模和凹模。型腔模多用仿形銑床加工、電火花加工和電解加工。將仿形銑加工與數控聯合應用和在電火花加工中增加三向平動頭裝置,都可提高型腔的加工質量。電解加工中增加充氣電解可提高生產效率。
Planar blanking dies can be formed by EDM, then formed grinding, coordinate grinding and other methods to further improve the accuracy. Forming grinding can be carried out by optical projection curve grinder, surface grinder with abnormal and polishing wheel mechanism, or by special forming grinding tool on precision surface grinder. The coordinate grinder can be used for precise positioning of the die to ensure precise aperture and spacing. The convex and concave dies of any curve shape can also be grinded by CNC continuous trajectory coordinate grinder. Profile milling machine, EDM and electrochemical machining are widely used for cavity die. Combining profiling milling with numerical control and adding three-way translational head device in EDM can improve the processing quality of the cavity. Increasing aerated electrolysis in ECM can improve production efficiency.
