Steel investment casting

Appropriate manipulator for semi-automatic drawing mold production, when drawing punch in die position, manipulator speed quickly, burr will fall on the upper punch, convex concave. To avoid this problem, we can do parts of the discharging test before production, setting up reasonable speed and discharging Angle of the manipulator, it won't run into parts and mould. Check truncation surface: truncation coil, will produce a lot of wear and tear to cutting mould attached to the blade tiny iron powder, so must be in before stamping production material check double truncation surface area or press line, and the clean sheet metal to remove burrs. Cleaning device check: sheet required Steel investment casting before production inspection and repair cleaning settled at the same time, so that it may be more effectively clean sheet, it is also a need to need, and also need to pay attention to the quality of the roll gap and cleaning oil. Method is in detail on a steel plate coated with red paint after wash settle its course, the current check red paint is undone before because of the shape, assume that removal rate is not up to standard, the required inspection and repair cleaning to settle. Cleaning oil when the lack of necessary cuts in a timely manner.
Avoid hardware stamping pressure bump between not delay of mould inspection and correction: drawing die need to do regular inspection and maintenance, in order to reduce the generation of convex concave and maintain a stable state. Common practice is to use the sample check pressure rim of adhesive scratch and machined surface (die, punch corner fillet). Shear modulus non standard fasteners of the check and correction: after shearing process of convex concave reason is due to the shear produced in the process of iron powder, therefore must watch before stamping iron powder, avoid the happening of convex concave.
Plate volume wide choice in steel specification types, whether scale plate or coil plate, the same material, material thickness of material, roll width different selling prices. So, want to reduce the cost, from purchasing volume wide fluctuation kongfu, on the premise of guarantee the material utilization as far as possible choose not premium volume wide range. As for scale board as far as possible to choose the appropriate size, from steel mills, after the completion of shear needn't to secondary shear, reduce cost of shear; For rolled plate, as Stainless steel foundry far as possible choose uncoiling forming coil specification and process, to reduce the workload of the secondary shear, improve work efficiency. Thickness deviation of choose the thickness of the plate there is a deviation request, usually in the range of deviation permit, should first choose the deviation of the plate, thus saving purchasing cost.
Material and material thickness metal stamping procurement cost saving method in product design when select material, avoid to choose high grade material cause excess product performance, at the same time, on the premise of meet the requirements of product, process, metal stamping factory try to choose the materials used in the existing production models, material thickness, forming material platform, provide convenience for the subsequent procurement, inventory management. Such as ordinary manufacture key performance requirements is socket screw plug its ductility, so in accord with the request of the quality of the product as far as possible choose low grade of material. And for the selection of the material thickness, in addition to consider the strength of the body after forming, weight, and attention to the popularization of material thickness. Because of the special material thickness, suppliers, it is difficult to supply and the price is high.
