Abstract
The utility model relates to a flange structure molding die. An outer sleeve is arranged on the outside of a mandrel used for supporting an inner cavity of a product to be processed. A hollow cavity capable of imbedding an inner sleeve and the product to be processed is formed between the outer sleeve and the mandrel; the inner sleeve is installed in the outer sleeve; a gap capable of installing the product to be processed is arranged between the inner sleeve and the mandrel; an inner hole of the inner sleeve is a big end down stepped hole used for forming a flange structure; and a horizontal position of a step of the inner hole of the inner sleeve corresponds to the top of the mandrel. The flange structure molding die is used in conjunction with a stamping device, and the technical problems of disordered product metal inner flow lines, uneven metal volume distribution, poor product size precision, serious lack of materials and flash of the existing forging process can be solved.
Description
Technical field
But the utility model relates to a kind of pattern that uses in Car Drive Shaft sliding end transverse shifting flange form housing process.
Background technology
The production method that transversely movable flange form forges housing in the sliding end of original Car Drive Shaft mainly contains blanking → heating → carry out the blank processing and forming at large-scale multistation warm forging forcing press, after annealing, pickling, phosphatization are processed, finishing or unite the production method of transversely movable flange form forging housing in the sliding end of finishing Car Drive Shaft with two kinds of different forming methods of cross wedge rolling and cold-extrusion technology on the cold forging forcing press.Adopt the original production method, blank behind jumping-up directly enters impression and is shaped, because metal volume distribution is unreasonable, the place that these materials are many does not have sufficient source, form and lack the material phenomenon, the a large amount of burr of local product that should not materials, form the overlap shape, both wasted material, reduced the product size precision, increased the following process operation, simultaneously strengthen again the metal level projected area, the mould bearing capacity is strengthened, shortened the mold use life-span, greatly reduce production efficiency, improved production cost.
Summary of the invention
But the utility model provides the flange arrangement mould that uses in a kind of sliding end transverse shifting flange form housing production and processing of Car Drive Shaft.
The technical solution of the utility model is: the mandrel that is used for support processed product inner chamber has overcoat outward; Formation one can be inserted the cavity of inner sleeve and processed product between overcoat and the mandrel; Be set in the overcoat in described; One gap that can pack processed product into is arranged between described inner sleeve and the mandrel; Described inner sleeve endoporus is the up big and down small stepped hole that is used to form flange arrangement; The horizontal level at described inner sleeve endoporus step place is corresponding with the mandrel top.
The utility model is combined with decompressor, can solve the inherent streamline entanglement of existing resultant metal in the existing Forging Technology, metal volume skewness, product size low precision, serious scarce material and the technical problem of overlap.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is work completed state schematic diagram of the present utility model.
Among the figure, 1, overcoat, 2, inner sleeve, 3, mandrel, 4, processed product, 5, decompressor.
The specific embodiment
Among Fig. 1, Fig. 2, for outside the mandrel 3 that supports the processed product inner chamber overcoat 1 being arranged; Formation one can be inserted the cavity of inner sleeve 2 and processed product between overcoat 1 and the mandrel 3; Inner sleeve 2 is loaded in the overcoat 1; One gap that can pack processed product into is arranged between described inner sleeve 2 and the mandrel 3; Inner sleeve 2 endoporus are the up big and down small stepped hole that is used to form flange arrangement; The horizontal level at inner sleeve 2 endoporus step places is corresponding with mandrel 3 tops.
Claims (1)
1. a flange arrangement mould is characterized in that: for overcoat (1) is arranged outside the mandrel (3) that supports the processed product inner chamber; Formation one can be inserted the cavity of inner sleeve (2) and processed product between overcoat (1) and the mandrel (3); Described inner sleeve (2) is loaded in the overcoat (1); One gap that can pack processed product into is arranged between described inner sleeve (2) and the mandrel (3); Described inner sleeve (2) endoporus is the up big and down small stepped hole that is used to form flange arrangement; The horizontal level at described inner sleeve (2) endoporus step place is corresponding with mandrel (3) top.
