Abstract

The utility model belongs to the field of spinning molds in automobile hub manufacturing, and discloses a high-rigidity tapered sliding block telescopic automobile hub difficult-demolding spinning mold. The telescopic automobile hub difficult-demolding spinning mold is composed of a neck bush, an outer supporting sleeve, a bottom plate, a sliding block, a push rod and a tapered groove, wherein the neck bush and the outer supporting sleeve are fixed to the bottom plate. The telescopic automobile hub difficult-demolding spinning mold is characterized in that the tapered groove is located in the center of the mold, one end of the tapered groove is fixed to the bottom plate, a pull rod is connected into the tapered groove, a groove is formed in the periphery of a groove body of the tapered groove and connected with the telescopic sliding block, the inward-shrinkage push rod is located outside the pull rod connected with the tapered groove, one end of the inward-shrinkage push rod is flush with the lower end of the groove opening of the tapered groove, and the inward-shrinkage push rod is in clearance fit with both the neck bush and the pull rod. Due to the fact that no frequently-used spring or thread structure is used, and the mold is reliable in demolding, simple in structure, convenient to install and arrange, high in rigidity and long in service life. No connection mark exists on a product where spinning is conducted. The mold can conduct hot spinning and cold spinning on an automobile hub.

Description

The difficult demoulding spinning mold of a kind of retractable vehicle wheel hub
Technical field
The utility model belongs to the spinning mold field in automotive hub manufacture, is 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 purpose of the present utility model 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 utility model object, 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 described in the utility model 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 described in the utility model 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 utility model advantage is: 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.
Brief description of the drawings
Fig. 1 is automotive hub A-A profile; In figure, 10-difficult demoulding region; 11-wheel rim; 12-spoke; 13-ring flange;
Fig. 2 is the difficult demoulding spinning mold of the utility model application structure schematic diagram; In figure, 1-patrix; 2-cone tank; 3-slide block; Automotive hub before 4-spinning; 5-interior contraction push rod; Automotive hub after 6-spinning; 7-neck bush; 8-pull bar; 9-outer support cover.
Detailed description of the invention
For the utility model 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 described in the utility model 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.
