The economy and manufacturability analysis of stamping parts

Metal stamping parts is to rely on press and die for sheet, strip, pipe and profile applying external force, such as plastic deformation or scattered, thus losing the required shape and size of the workpiece, Stamping parts) The forming of the point. Stamping and casting belong to plastic processing ( Or pressure processing) , called the forging press. Stamping of billet is important hot rolling and cold rolling steel plate and steel belt. Stamping can make other essentials are difficult to manufacture with enhanced, rib, heave or flanging of stamping parts processing, in order to progress its rigidity. Due to accept close mold, workpiece precision can reach micron grade, and high precision, specifications are equally repeatedly, can punch a hole nest, convex sets, etc. The economy and manufacturability analysis of stamping parts. 1, stamping parts of the economy analysis: according to the product figure or prototype, understand the requirements and functions of stamping parts, according to the shape of the structure of the stamping characteristics, size, precision requirement, production batch and raw material performance, analysis of material utilization; Whether to simplify the mold design and manufacturing; Stamping production and processing characteristics whether adapt; The stamping processing is economic. 2, dongguan hardware stamping manufacturability analysis: according to the product figure or prototype, shape, size, accuracy of stamping parts, materials, performance analysis, judge whether to conform to the requirements of the stamping process; How easy is it ruled that the stamping parts processing; Determine whether a process need to take special measures. All who pass by analysis, found that the stamping manufacturability is bad ( Such as product parts in the figure shape is too complex, high dimensional accuracy and surface quality, dimensioning and benchmark selection, improper material selection and unreasonable, etc. ) , but in the product design personnel, on the premise of guarantee performance, shape, size, accuracy of stamping parts and raw materials make necessary changes. Parts left R3mm under the condition of material thickness is 4 mm to stamping out, by the modified parts are easier to stamping out. Car muffler back cover, on the premise of guarantee the use requirement, after modify the shape is simple, good manufacturability, stamping process by eight times reduced to 2 times, material consumption is reduced by half. As shown in figure 8 - 3 automobile headlight enclosure, modify need 5 times before drawing, pickling, annealing, 2 times of the modified lamp shell, 1 deep drawing, both guarantee the use requirement, and save materials, reduce working procedure, reduces the cost. A: metal stamping parts market is not perfect and sound
