Abstract
The utility model discloses moulding equipment for a bicycle aluminium-alloy stem, comprising a stem shape die and an oil pressure punch mechanism, wherein the stem shape die comprises an upper die and a lower die which are symmetrical in structure; after the upper die and the lower die are assembled, a bicycle aluminium-alloy stem die cavity is formed therebetween; the front end of the bicycle aluminium-alloy stem die cavity is a closed end and formed to be the shape of the head of the bicycle aluminium-alloy stem, and the rear end of the bicycle aluminium-alloy stem die cavity is an open end; the oil pressure punch mechanism comprises a telescopic main punch; the front end of the main punch is formed to be the shape of the tail of the bicycle aluminium-alloy stem; a telescopic sub punch is disposed in the main punch; and the oil pressure punch mechanism can be inserted in the bicycle aluminium-alloy stem die cavity from the open end of the bicycle aluminium-alloy stem die cavity. The bicycle aluminium-alloy stem manufactured by the moulding equipment for a bicycle aluminium-alloy stem disclosed by the utility model is less in material consumption and high in moulding yield; and the moulded products have the same shape and dimension, and have no need to be further intricately machined by follow-up equipment, so that production cost is decreased and production efficiency is increased.
Description
Technical field
The utility model relates to and a kind ofly belongs to the bicycle part field from motor-car aluminium alloy standpipe, concrete relates to a kind of bicycle aluminium alloy standpipe former.
Background technology
The manufacturing approach of bicycle aluminium alloy standpipe is open forging at present, and this kind method moulding feed consumption is big, and the moulding yields is low, and the product design size difference after the moulding is bigger, needs further loaded down with trivial details processing of follow-up equipment.
The utility model content
For overcoming the problems of the prior art, the purpose of the utility model is to provide a kind of bicycle aluminium alloy standpipe former and moulding process.
In order to solve the problems of the technologies described above, realize above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of bicycle aluminium alloy standpipe former; It comprises a standpipe profile mould and an oil pressure plunger mechanism; Said standpipe profile mould comprises the upper die and lower die of symmetrical configuration; In the middle of behind the said upper die and lower die matched moulds is a bicycle aluminium alloy standpipe die cavity, and the front end of said bicycle aluminium alloy standpipe die cavity is that shape, the rear end of blind end and one-tenth bicycle aluminium alloy standpipe head is the open end; Said oil pressure plunger mechanism comprises a telescopic main drift, and the front end of said main drift is shaped to the shape of bicycle aluminium alloy standpipe afterbody, is a telescopic sub-drift in the said main drift; Said oil pressure plunger mechanism can insert in the said bicycle aluminium alloy standpipe die cavity from the open end of said bicycle aluminium alloy standpipe die cavity.
A kind of moulding process of bicycle aluminium alloy standpipe, it may further comprise the steps:
Step 1) constitutes said bicycle aluminium alloy standpipe die cavity with said upper die and lower die matched moulds;
Step 2) a solid aluminium stock is inserted in the said bicycle aluminium alloy standpipe die cavity;
The said oil pressure plunger mechanism of step 3) inserts in the said bicycle aluminium alloy standpipe die cavity; And push said aluminium stock and make the front end of said aluminium stock push the blind end of said bicycle aluminium alloy standpipe die cavity, cause the front end of said aluminium stock to be shaped to the shape of said bicycle aluminium alloy standpipe head;
The said main drift power of unloading of step 4) is retreated to desired location; Simultaneously said sub-drift continues in said bicycle aluminium alloy standpipe die cavity, to push; It is hollow to cause originally solid aluminium stock to be squeezed into, and makes the shape of the said bicycle aluminium alloy of tail end moulding standpipe afterbody of said aluminium stock;
Said main drift of step 5) and sub-drift return to initial position, open the product after said upper die and lower die take out moulding.
Compared with prior art the utlity model has following advantage:
The bicycle aluminium alloy standpipe moulding process of the utility model accomplishs without any letup; Shaped article need not to cut edge, and reduced 40% than existing moulding process feed consumption, and interstitial hole is found time; Make the weight of the product after the moulding alleviate greatly; Alleviated 50% than existing moulding process, process velocity is improved, and compares with existing moulding process and has improved about 20%.
The bicycle aluminium alloy standpipe feed consumption that the utility model is made through bicycle aluminium alloy standpipe former is few, the moulding yields high; Product design after the moulding is measure-alike; Need not follow-up equipment further loaded down with trivial details processing, greatly reduce production cost, improved production efficiency.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
