A kind of aluminium alloy wheel hub mould suspension hook
Technical field:
The utility model relates to a kind of suspension hook, and specifically, the utility model relates to a kind of aluminium alloy wheel hub mould suspension hook.
Background technology
Low pressure [die has become the important process of producing the aluminium alloy automobile foundry goods, and automotive hub mainly adopts low-pressure casting process production, and reason is that the aluminium alloy automobile hub productive output is big, and inside quality is strict.A representative type low pressure [die die-cast machine generally includes electro heat smelting furnace and mould, and the mould of aluminium alloy wheel hub generally comprises 4 parts: patrix, counterdie and two limit moulds.
First technology of general low pressure [die is exactly cleaning mold, and the material of aluminium alloy wheel hub upper mould and counterdie is the H13 steel, and the material of limit mould is a cast iron, so all very heavy, upper and lower mould particularly, and volume ratio is bigger.How to use manpower as much as possible less; Be the difficult problem that the automotive hub production industry will solve always, how solve will have heavier mould to put into the problem of bench board cleaning, and the card that at first will solve mould hangs problem; Because upper and lower mould is specifically long-pending bigger, and the mould top and bottom are irregular.Existing hoisting system uses very inconvenient, and need move to bench board with manpower with mould after rising to podium level with lifting mechanism; Labour intensity is big; Inefficiency, poor stability is badly in need of having a kind of lifting wheel hub mould up and down that is applicable to; Safety performance is good, and suspension hook easy to use is applied to cleaning mold technology.
The utility model content
The purpose of the utility model is to provide a kind of reasonable in design, simple, laborsaving, the suspension hook that is used to lift by crane the aluminium alloy wheel hub mould.
The purpose of the utility model realizes through following technical scheme: a kind of aluminium alloy wheel hub mould suspension hook is provided, and it comprises suspension ring, movable arm and grab, and described suspension ring are made by the steel pipe of hollow; Described movable arm has two; Become symmetry shape, each movable arm makes things convenient for the card of the big mould of volume ratio to hang by the radian of 145 ° of large diameter bar bending written treaties; For keeping radian to be provided with bracing frame in the movable arm inboard; Support frame as described above is welded by the reinforcing bar of minor diameter, and there is the skin that is movably connected in suspension ring described movable arm upper end, and the lower end is provided with grab.
The beneficial effect of the utility model is: be used for aluminium alloy wheel hub mould suspension hook and have simple, advantage such as preparation is simple and easy, easy to operate, safety performance is good rational in infrastructure, can reduce labour intensity, raise labour efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model aluminium alloy wheel hub mould suspension hook.
Among the figure: suspension ring 1 flexibly connect 2, movable arm 3, bracing frame 4, grab 5.
The specific embodiment
As shown in Figure 1, the utility model aluminium alloy wheel hub mould suspension hook comprises suspension ring 1, movable arm 3 and grab 5, and described suspension ring 1 are made by the steel pipe of hollow; Described movable arm 3 has two; Become symmetry shape, each movable arm 3 makes things convenient for the card of the big mould of volume ratio to hang by the radian of 145 ° of large diameter bar bending written treaties; For keeping radian to be provided with bracing frame 4 in movable arm 3 inboards; Support frame as described above 4 is welded by the reinforcing bar of minor diameter, and there are 2 skins at suspension ring of flexible connection the upper end of said movable arm 3, and the lower end is provided with grab 5.
Method of application is following: before using suspension ring 1 are hung on the overhead traveling crane suspension hook; When lifting, only need to block both sides grab 5 respectively the edge of aluminium alloy wheel hub mould; Movable arm 3 upper ends are to be movably connected in suspension ring 1 skin; Because the action of gravity of mould makes both sides grab 5 produce inside clamping power, thus the tightness when having guaranteed to sling mould.After hanging the appropriate location, let suspension hook descend, both sides grab 5 is removed from die edge got final product.
