Abstract
A gland forming die for an air bag gas generator comprises a fixed die and a movable die, wherein an outer ring cavity and an inner ring cavity are arranged in the fixed die, an annular slide block matched with the cavity is arranged at the bottom of the outer ring cavity, and the slide block is connected with an external force control mechanism. The external force control mechanism is a hydraulic or pneumatic or spring mechanism. The utility model is used for hot forging air bag gas generator gland can improve product machining precision and production efficiency, and the mould atress is balanced, reasonable, and long service life uses with low costsly, especially is fit for big batch, automated production.
Description
Technical field
The utility model relates to a kind of metal fever forging mould, specifically is the finishing die that is used for safety air bag gasifier pressure cover forge hot processing.
Background technology
Air-cushion inflator is the critical component of automobile safety system, and its gland and housing form altogether and hold the detonate container of medicament and gas producing medicinal of air bag.The gland material is an aluminium alloy, generally is inside and outside layer circulus, and its outer shroud wall thickness is thick greater than internal ring wall, and the outer shroud height is less than interior ring height.At present, the manufacturing process of gland has machining process, casting method, and the former stock utilization is low, and it is many to take equipment, production efficiency is low, the cost height, and latter material's utilization rate is moderate, and it is few to take equipment, cost is low, but the part machinery poor performance, two kinds of methods only are applicable to trial-manufacture of sample.In addition, also have forging method, with the aluminum alloy blank press forming in forging die after the heating, this method is saved material, and production efficiency height, its key problem in technology are the structure and the performance of shaping dies.In the present used shaping dies, the inner and outer rings die cavity all is changeless, because the difference on the workpiece inner and outer rings size, material at first flows to the outer shroud die cavity, it is then relatively more difficult to flow to the inner ring type chamber, cause the mould discontinuity equalization like this, reduce service life, also influence processing precision of products simultaneously.
The utility model content
The technical problems to be solved in the utility model is the weak point that overcomes existing hot-forging die, provides a kind of and can improve processing precision of products, prolongs die life, is fit to safety air bag gasifier pressure cover finishing die in enormous quantities, automated production.
The technical solution of the utility model is: the safety air bag gasifier pressure cover finishing die comprises fixed half and moving half, outer shroud die cavity and inner ring type chamber are arranged in the cover half, outer shroud die cavity thickness is greater than inner ring type chamber thickness, outer shroud die cavity height is less than inner ring type chamber height, improvements are that described outer shroud cavity bottom is provided with the ring-type slide block that matches with die cavity, and this ring-type slide block is connected with the external force controlling organization.
Above-mentioned external force controlling organization is a hydraulic mechanism, perhaps is pneumatic mechanism, perhaps is spring mechanism, and mechanism puts on the external force of slide block and can regulate by control valve, nut, screw rod etc.
Adopt above technical scheme, be provided with the ring-type slide block that links to each other with the external force controlling organization owing to the outer shroud cavity bottom in this finishing die, suitable resistance is provided when workpiece outer shroud structure formation, its flowing velocity is slowed down, force material more multithread to the inner ring type chamber, slide block finally retreats to outer shroud cavity bottom desired location, workpiece inner and outer ring height is shaped reaches requirement.During this mold work, earlier aluminum alloy blank is heated to mecystasis, material flows and is tending towards balanced in the inner and outer rings die cavity, can improve processing precision of products, it is best that the stressed distribution of mould reaches, and effectively prolongs die life, reduce application cost, especially be fit in enormous quantities, automated production.
Description of drawings
Accompanying drawing is the utility model main part structural representation.
The specific embodiment
As figure, dynamic model 1 is main loading section, form outer shroud die cavity and inner ring type chamber by the joint portion between the fixed block 2,4,5 in the cover half, wherein the outer shroud cavity bottom is provided with the ring-type slide block 3 that matches with die cavity, this slider bottom links to each other with hydraulic mechanism (not drawing among the figure), provide resistance during to the outer shroud structure formation of workpiece 7 under external force control, the material of workpiece inner and outer rings structure is flowed be tending towards balanced, discharge arm 6 is used to eject the workpiece after the shaping.
Claims (4)
1, a kind of safety air bag gasifier pressure cover finishing die, comprise fixed half and moving half, outer shroud die cavity and inner ring type chamber are arranged in the cover half, outer shroud die cavity thickness is greater than inner ring type chamber thickness, outer shroud die cavity height is less than inner ring type chamber height, it is characterized in that described outer shroud cavity bottom is provided with the ring-type slide block that matches with die cavity, and this ring-type slide block is connected with the external force controlling organization.
2, by the described safety air bag gasifier pressure cover finishing die of claim 1, it is characterized in that: described external force controlling organization is a hydraulic mechanism.
3, by the described safety air bag gasifier pressure cover finishing die of claim 1, it is characterized in that: described external force controlling organization is a pneumatic mechanism.
