Abstract
The invention belongs to the field of flow forming moulds in automobile hub manufacture, and discloses a high-rigidity flow forming mouldused for difficulty in demoulding of the retractable type automobile hub and provided with tapered slide blocks. The flow formingmould comprises an inner bushing, an outer support sleeve, a baseplate, slide blocks, a push rod and a tapered groove, wherein the inner bushing and the outer support sleeve are fixed tothe baseplate respectively; the flow forming mould is characterized in that the tapered groove is positioned in the center of the mould, one end of the tapered groove is fixed tothe baseplate, a pull rod is connected with the interior of the tapered groove, a groove is formed in the periphery of the body of the tapered groove, and the groove is connected with the retractable slide blocks; aninward-contraction push rod is positioned on the outer side of the pull rod connected with the tapered groove, one end of the inward-contraction push rod is in parallel and level with the lower end of the groove mouth of the tapered groove, and the inward-contraction push rod and the inner bushingand the inward-contraction push rod and the pull rod are in clearance fit. According to the flow forming mould, frequently-used springs and screw thread structures are not adopted, so that the demoulding of the mould is reliable, the structure is simple, the mounting and the debugging are convenient, the rigidity is high, and the service life is long; meanwhile, flow forming products have no connecting marks, so that the hot flow forming and the cold flow forming tothe automotive hub can be conducted by the mould.
Description
Technical field
The invention belongs to the spinning mold field in automotive hub manufacture, be specifically related to the difficult demoulding spinning mold of a kind of high rigidity conical sliding block retractable vehicle wheel hub.
Background technology
For difficult demoulding mould, that diel or forging mold or spinning mold are all the moulds of difficult design in mould, conventionally, the major defect of difficult demoulding mould be install, debug difficulties, rigidity is poor, complex structure, reliability is low, and can strengthen the wearing and tearing of mould along with the increase of operational forces, thereby general service life is lower, but do not adopt complicated mechanism, be difficult to again realize the demoulding, this is also the most scabrous problem of the difficult demoulding.Automobile industry development is very fast at present, and automotive hub demand constantly rises, and Machining Automobile Wheel Hub Mould is improved, and is conducive to improve automotive hub quality, promotes industry development.
Summary of the invention
The object of the invention is taking typical serial automotive hub product as carrier, provide that a kind of rigidity is high, long service life, simple in structure, dependable performance, installation and debugging difficult demoulding spinning mold easily, serial difficult demoulding automotive hub can be produced, hot spinning and the cold spinning of automotive hub can be carried out.
For realizing the object of the invention, technical solution is as follows:
Based on the biological principle that the flowers are in blossom and shrink, taking slide block mechanism as main Mechanism Combination form, and in conjunction with the force-increasing mechanism of taper, can successfully realize the demoulding, and forms of motion is relative sliding, do not adopt spring and helicitic texture, thereby the rigidity of structure is large, can realize hot spinning and cold spinning.
The difficult demoulding spinning mold of retractable vehicle wheel hub of the present invention is made up of neck bush, outer support cover, base plate, slide block and push rod, cone tank, neck bush, outer support cover are individually fixed on base plate, it is characterized in that, cone tank is positioned at mold center, one end is fixed on base plate, cylinder lever connecting rod in cone tank, cone tank cell body periphery is provided with groove, and groove connects expansion sliding block; Interior contraction push rod is positioned at cone tank institute cylinder lever connecting rod outside, and interior contraction push rod one end is concordant with cone tank notch lower end, and interior contraction push rod and neck bush and pull bar are matched in clearance, between outer support cover and neck bush, is interference fit.
The difficult demoulding spinning mold of retractable vehicle wheel hub of the present invention can be determined slide block quantity and shape according to automotive hub shape, spoke quantity.The preferred 5-7 of slide block quantity, shape preferred stripe shape.
The invention has the advantages that: the force-increasing mechanism that adopts slide block mechanism, taper, demoulding campaign is taking relative sliding as main, because not adopting conventional spring and helicitic texture, thereby this mold releasability is reliable, simple in structure, installation and debugging are convenient, and rigidity is high, long service life, and spinning product is without connecting trace, this mould can carry out hot spinning and the cold spinning of automotive hub, is applicable to very much suitability for industrialized production application.

Detailed description of the invention
For the present invention is better illustrated, as follows for embodiment by reference to the accompanying drawings:
Embodiment 1
As accompanying drawing 2, the difficult demoulding spinning mold of retractable vehicle wheel hub of the present invention is made up of neck bush (7), outer support cover (9), base plate, slide block (3) and push rod, cone tank (2), neck bush (7), outer support cover (9) are individually fixed on base plate, it is characterized in that, cone tank (2) is positioned at mold center, one end is fixed on base plate, the interior cylinder lever connecting rod of cone tank (2) (8), cone tank (2) cell body periphery is provided with groove, and groove connects several strip expansion sliding blocks (3); Interior contraction push rod (5) is positioned at cone tank (2) institute's cylinder lever connecting rod (8) outside, and interior contraction push rod (5) one end is concordant with cone tank (3) notch lower end, and interior contraction push rod (5) is matched in clearance with neck bush (7) and pull bar (8).Slide block (3) quantity is selected 5, and shape is selected strip.
Application examples 1
The automotive hub produced of the spinning of wanting product sketch as shown in Figure 1,10 regions in Fig. 1 are difficult demoulding region after spinning, under normal circumstances cannot the demoulding, must adopt bascule.Adopt the difficult demoulding spinning mold of the present invention, in process of production, as shown in Figure 2, first be that taper pull bar (8) is boosted, 5 slide blocks (3) are outwards stretched, taper pull bar (8) and 5 slide blocks (3) are coordinated and are slided by cone tank (2), during to assigned address, clearance spaces between two spokes, because 5 slide blocks outwards exist gap after stretching, extension, the top mould in this gap (1) is depressed and is made up, and compress automotive hub by patrix (1) and outer support cover (9), at this moment, spinning roller just can be spun to according to certain track the wheel-rim shape of wheel hub, after machining, patrix (1) is upwards return, taper pull bar (8) is return downwards, wherein, interior contraction push rod (5) is matched in clearance with neck bush (7) and taper pull bar (8), interior contraction push rod 5 is boosted, with taper pull bar (8) relative sliding, slide block (3) is by the propelling of interior contraction push rod (5), 5 slide blocks (3) are inwardly shunk, be retracted to the upper outer edges place of outer support cover (9), now, wheel hub after spinning just can take out from mould, whole rotary pressing processing finishes.
