Description
Technical field
The utility model belongs to plate progressive molding processing technique field, is specifically related to a kind of device that utilizes high-pressure hot wind processing plastic plate.
Background technology
Plastics owing to thering is high specific strength and specific stiffness, good chemical stability and lower-price characteristic obtains applying more and more widely in fields such as medical science, aviation and automobile makings.But plastics are shaped and must be carried out under molten state or elastomeric state, processing plastic plate energy consumes high, it is high that equipment and mold drops into, and therefore, traditional production process also is not suitable for the exploitation of new product and the production of single-piece, small lot plastic part.And original RP technique (RPM) plastics used mainly are limited to the special plastics such as photosensitive resin, acrylic compounds and epoxies, expensive, applicable surface is narrow, and very large limitation is being arranged aspect the shaping of plastic part.
The progressive molding technology is the new technology that development in recent years is got up, progressive molding does not need mould or only needs pattern, can complete fast the shaping of part by the 3D model of workpiece, be particularly suitable for the production of single-piece or parts in small batch, there is the advantages such as material that cost crystallized ability low, plate is high, traditional punching press that can be shaped is difficult to shaping.
The progressive molding technology is mainly used in processing sheet metal component at present, adopts the bibliographical information of progressive molding technology shaping plastic also few.Before 4 years, Franzen etc. are successfully used the single-point progressive molding technology commercial PVC plate that is shaped for the first time; But Martins has studied the progressive molding performance of the common plastics plates such as POM, PE, PA and PC, find no matter be unformed plastics or high-crystallinity plastics, the plastics plate can both be configured as to the plastic products with certain depth smoothly.Can judge, the progressive molding technology can make up the deficiency of original rapid shaping technique, adopts general-purpose plastics, can process the plastic casing class part with very complex degree, and cost is low, and the cycle is short.
The progressive molding process of current plastics plate, all adopt normal temperature plastics plate, without external heat, only rely on friction between tool heads and plate to promote the temperature of plastics plate, thereby the temperature while causing the plastics sheet forming is too low, elongation at break is not high, thereby can't give full play to its deformability.
Summary of the invention
The above-mentioned technical problem existed in order to overcome the prior art field, the purpose of this utility model is, a kind of plastics plate high-pressure hot wind progressive molding device is provided, can improves plastics plate forming limit, realize the progressive molding processing of the little product of the complicated shape to middle batch.
The plastics plate high-pressure hot wind progressive molding device that the utility model provides, described plastics plate high-pressure hot wind progressive molding device is arranged on the Metal CNC Incremental Forming lathe, it comprises air compressor, heating system, valve, infrared thermometer, clamping device, described air compressor is connected with heating system by pipeline, and described heating system is connected with valve by bend pipe; Plastics plate high-pressure hot wind progressive molding device, it also comprises connecting rod and fixed head, described bend pipe is fixedly mounted on fixed head; It also comprises pull bar, the left and right two ends that are symmetricly set on the Metal CNC Incremental Forming lathe of described pull bar, and described clamping device comprises hollow support platform and blank holder, described hollow support platform is arranged on pull bar; Described infrared thermometer is arranged on the top of plastics plate.
The plastics plate high-pressure hot wind progressive molding device that the utility model provides, its beneficial effect is, adopt compressed air to replace metal tools of the prior art to apply deformation force, can avoid plastics plate both sides to contact with two tool and moulds, prevent from being distorted and tearing because local elongation load is excessive simultaneously; Adopt the local pointwise heating of plastic of hot blast plate, make the plastics plate under elastomeric state, greatly reduced the resistance of deformation of plastics plates, improved the forming property of plastics plates.
