Pipe making mold

Affiliated technical field

The present invention relates to a kind of mould of tuber.

Technical background

At present the mould that uses of tuber is made up of two relative moulds that roll, because this mould specificity is very strong, produces a kind of pipe of specification, needs use a mold, and the specification of pipe is many, and the quantity of mould is just many, can not replace each other, and mould is invested greatly; Other two roller die tool working surface unbalance stress, frictional resistance is big, hinders pipe.A kind of Pipe making mold that mould constitutes that rolls more, the two above-mentioned shortcomings of rolling mould have been solved, but should roll the mould technology is in the junior stage more, for example axostylus axostyles that roll mould are contained on the movable support more, make and roll mould more and can also on template, rotate by support simultaneously rotating on the axostylus axostyle, roll the rotation of mould both direction, complex structure more, job insecurity makes tubulation quality instability; Because the rotation of both direction can only be made driven pulley and use, and it has limited technological innovation, existing tuber is existed produce line length in addition, the problem that floor space is big can't solve.

Summary of the invention

The objective of the invention is: a kind of Pipe making mold is provided, and this mould has versatility, can improve the mould utilization rate when producing different size tubing, improves the tubulation quality, and production line is shortened, and reduces floor space.

Technical scheme of the present invention is: a kind of Pipe making mold, comprise template, it is characterized in that: entad be equipped with on the template and arrange many groups of surrounding tubulation moulding hole and roll mould, being located at its two ends of axostylus axostyle of rolling the mould center is fixed on the template, described its side of mould of rolling can be bevel gear, adjacent rolls the connection that is meshed of mould bevel gear.Rolling the bevel gear of mould and the travelling gear on the power transmission shaft is connected with a joggle.Described template can be patrix and is connected and composed by bolt with following die combination.The working face carving that rolls the mould circumference has decorative pattern.

The advantage of present technique is: the axostylus axostyle two ends that 1, will respectively roll mould directly are packed on the template, have omitted existing travel(l)ing rest, roll mould and become directed rolling on template, stable when rolling mould and bearing external force, make tubulation moulding hole shape stable, thereby improved the tubulation quality, simplified mould structure.2, roll mould and be meshing with each other by bevel gear and be linked to be an integral body, it is passive when rolling mould and using to do, and respectively rolls mould and can cooperate close synchronization to roll.After intermeshing bevel gear was connected with a joggle with travelling gear again, the passive mould that rolls had just become and has initiatively rolled mould, can promote tubing and advance, and therefore can omit original tube-pulling apparatus, shortens production line, reduces floor space.3, after the combining form, fine-tuning caliber was produced non-specification pipe, satisfies user's specific (special) requirements about template was become by original integral form.4, because gang form, so, can only use the counterdie of template, and save the mould investment, give also fixedly that core brings convenience in tuber input section, when dismantling mould, need not cut off pipe can finish, made things convenient for maintenance.5, present technique adopts many groups to roll the technical pattern that mould is entad arranged, be to improvement in preceding patented technology, therefore present technique has the advantage that above-mentioned advantage has kept prior art simultaneously, and for example Pipe making molds that roll the mould composition have versatility more, when changing the specification of moulding pipe, only change the mould at tuber two ends, middle section die is shared, both can change the tubing aperture, so improved the mould utilization rate, can reduce number of molds, and reduce production costs; Roll mould for another each and entad arrange, stressed even, thus little with the frictional resistance of moulding pipe contact-making surface, do not hinder pipe.
