Abstract
The invention belongs to the spinning mold field in automotive hub manufacture, disclose the difficult demoulding spinning mold of a kind of high rigidity conical sliding block retractable vehicle wheel hub.It 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 outside cone tank institute cylinder lever connecting rod, 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.Because not adopting conventional spring and helicitic texture, this mold releasability is reliable, and structure is simple, and installation and debugging are convenient, and rigidity is high, long service life, and spinning product is without connection trace, and this mould can carry out hot spinning and the cold spinning of automotive hub.
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, the mould of the most difficult design in mould that to be diel or forging mold or spinning mold be all, usually, 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, thus 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.Current automobile industry development is very fast, and automotive hub demand constantly rises, and improves Machining Automobile Wheel Hub Mould, is conducive to improving automotive hub quality, promotes industry development.
Summary of the invention
The object of the invention is with the automotive hub product of typical case's series for carrier, there is provided that a kind of rigidity is high, long service life, structure are simple, dependable performance, installation and debugging difficult demoulding spinning mold easily, the difficult demoulding automotive hub of series 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, be main Mechanism Combination form with slide block mechanism, and in conjunction with the force-increasing mechanism of taper, successfully can realize the demoulding, and forms of motion is relative sliding, does not adopt spring and helicitic texture, thus, 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 outside cone tank institute cylinder lever connecting rod, 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, is interference fit between outer support cover and neck bush.
The difficult demoulding spinning mold of retractable vehicle wheel hub of the present invention can according to automotive hub shape, spoke quantity determination slide block quantity and shape.The preferred 5-7 of slide block quantity, shape preferred stripe shape.
The invention has the advantages that: the force-increasing mechanism adopting slide block mechanism, taper, stripping movement is based on relative sliding, because not adopting conventional spring and helicitic texture, thus, this mold releasability is reliable, structure is simple, installation and debugging are convenient, and rigidity is high, long service life, and spinning product is without connection 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 better illustrating the present invention, 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, cone tank (2) interior cylinder lever connecting rod (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 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 selects 5, and shape selects strip.
Application examples 1
Want spinning to produce automotive hub product sketch as shown in Figure 1,10 regions are in FIG 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 by cone tank (2) to be slided, during to assigned address, clearance spaces between two spokes, due to 5 slide blocks outwards stretch after there is gap, the top mould in this gap (1) pressure makes up, and compress automotive hub by patrix (1) and outer support cover (9), at this moment, spinning roller just can be spun to the wheel-rim shape of wheel hub according to certain track, 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 terminates.
