The Characteristics Of The Car Covers

The development of body coverings is related to the automobile structure, the body strength, large-scale production process, manufacturing costs, and many other fields, multidisciplinary knowledge, so for the design of the complete coverage must be produced in accordance with the requirements of the sample, do a lot of testing, only the test proved that the qualified body cover can be put into production and manufacturing.Car Covers

At present, the main solution is the drawing and shaping problem of the body covering parts, blanking, trimming and opening work are generally done by laser cutting or manual. For r round Corners require not high flanging, folding and other work generally by the relevant fixture positioning, manual completion, for the high requirements of flanging can be used by the press or the use of special flanging equipment. Therefore, the forming and drawing die of Autobody panel is the key to the whole body trial.Car Covers

The characteristics of the prototype of the body covering parts are: few pieces of production, usually from several to dozens of pieces; short cycle, such as the entire sample production cycle of the door inner plate is only one to 1.5 months; quality is close to mass production parts, such as the Datum point of the trial parts (RPS point), batch inspection point (PMP point), The matching surface size point (CP point) must be qualified, the size of the super near (BK Point) in a single part of the general can not exceed 2. Today, the major automotive design units are widely used in the rapid tooling method to make the body cover sample, the main methods are: Low melting point alloy mold, polyurethane mold, metal spraying mold, based on the discrete surface of the die-free stamping. Among them, the low melting point alloy mold is using the polyurethane material Master Mold, uses the low melting point alloy directly to pour out the concave mold and the pressing edge circle mold.Car Covers

It is suitable for the design of complex deep drawing and drawing die, the verification of stamping process and die surface design, the optimization of forming parameters, the minimization of material and lubricant consumption, the evaluation and optimization of new sheets (such as tailor-welded plate, composite plate).Car Covers
