Description
Technical field
The utility model relates to plate material parts partial plastic forming mold toolings such as magnesium alloy, especially is fit to the partial plastic forming of needs and the interconnective magnesium alloy plate electronic product casing of other part part.
Background technology
Along with the raising of people's living standard, paying attention to more and more paying attention to product appearance and safety in utilization on the practicality of electronic product, the durable basis, reduce unhealthful microwave radiation as far as possible, magnesium alloy becomes the first-selection of numerous structural materials with its good performance.It shows more actively in 3C (computer, communication product, consumer electronics) magnesium alloy case product development application facet.At first, be made up of the precise electronic part because 3C Product inside is many, external shock is born by housing, the comparable engineering plastic of magnesium alloy provides higher structural strength, and anti-seismic performance is good, improves the durability of product; Has electromagnetic shielding characteristic owing to magnesium alloy on the other hand, the harm that the microwave radiation of minimizing electronic product causes surrounding environment; On the one hand because magnesium alloy has the good surface handling property, can obviously promote the senior image of product again.
At present, portable electronic product is being pursued compactly day by day, and this manufacturing technology to Mg alloy thin wall spare has proposed challenge.At present, Application of Magnesium mainly is a die casting, but adopts casting or semi-solid-state injection molding always to have certain porosity, and yield rate is low; In addition, cast member itself is because the technological requirement wall thickness can not be too thin, and the intensity of material is lower, and the intensity that improves thin-wall part must be cost to increase wall thickness.Extrusion process has obviously shown the deficiency of aspects such as stock utilization, product quality, the bottleneck of become the processing of thin-walled hull shape spare electronic product, using.The sheet material forming processing mode has significant advantage aspect raising parts quality, productivity ratio, the saving material, and can process the thin-walled parts that casting can't process, and the part of shaping has mechanical performance and surface quality preferably.
For the magnesium alloy plate processing that is shaped owing to be subjected to the influence of processing mode, the more difficult acquisition of the part that sheet material forming shapes can with the direct-connected structure of other part.Because wall is thin (about 0.6mm), the intensity that directly is threaded is restricted.In recent years, at magnesium alloy plate processing and manufacturing neck the hot impact forging technology of magnesium alloy has been proposed.By the press forging and forming of sheet material, obtain to have the part of local boss, follow-up to its processing generation screw connection structure.This method is feasible, but complex procedures, the equipment needed thereby tonnage is big, and cost is very high when especially being shaped the large-size part.Therefore, the utility model has proposed the mold tooling of magnesium alloy plate part syndeton partial plastic forming at the magnesium alloy plate part syndeton problem of present existence.
The utility model content
The purpose of this utility model provides a kind of mold tooling of magnesium alloy plate part syndeton partial plastic forming, can realize magnesium alloy plate part sidewall partial plastic forming, solve magnesium alloy plate part syndeton problem.
The technical solution of the utility model is:
A kind of mold tooling of magnesium alloy plate part syndeton partial plastic forming has partial plastic forming punch and corresponding partial plastic forming die, and described partial plastic forming die top is provided with pressing plate, and blank is interposed between pressing plate and the partial plastic forming die.
Described partial plastic forming punch bottom has the rectangle inclined-plane, and keen edge has been worn on rectangle inclined-plane three.
Dress electric heating tube in the described partial plastic forming die, partial plastic forming die upper surface has the corresponding rectangle shaping of the rectangle inclined plane shape oral area with the partial plastic forming punch, and the rectangle shaping oral area three of partial plastic forming die has been worn keen edge, and one side is a round-corner transition.
Described pressing plate, partial plastic forming die are rectangular configuration, in partial plastic forming die inside containing hole are arranged, and electric heating tube places in the containing hole.
The essence that the magnesium alloy plate parts locally is shaped is stamping-out and crooked combined shaping, and the built-in heating tube of die makes magnesium alloy resistance of deformation under heating condition low, and plasticity is good, reduces bending radius, improves beaming limit.During partial plastic forming, wherein a forming face occurs bending and deformation, and other three forming faces are out of shape at cutting edge effect down cut.Material and part noumenon do not take place to break away from fully in the forming process, finish partial plastic forming before fracture.
The utility model mould has been taken all factors into consideration the warm characteristic of magnesium alloy, the technical characterstic of partial plastic forming, can make the magnesium alloy plate part better realize partial plastic forming under the condition of palsticity.This technology has overcome local boss Hot press-forging formation, connecting thread machining complex procedures, the high deficiency of cost, and the partial plastic forming from sidewall realization syndeton reduces cost, and raises the efficiency.The interior boss that is shaped has the inclined-plane, is easy to clamp self-locking, connects reliable.For part, can guarantee whole bonding strength according to actual conditions many places partial plastic forming with longer joint face.
The utlity model has following advantage:
1, the utility model can be realized pressing plate, partial plastic forming die are heated, and can heat with mould blank simultaneously;
2, the utility model mold tooling can be realized magnesium alloy plate part sidewall partial plastic forming, forms plate material parts and connects new construction;
3, three detrusions of the part of the utility model mold tooling partial plastic forming, one side flexural deformation.The cutting edge forming face is straight, and curved ramp is easy to slide, assembling, and assembling back self-locking connects reliable;
4, the utility model mold tooling is simple in structure, and a time operation is finished partial plastic forming, and efficient height, cost are low.
