Description
The invention belongs to a kind of Versatile tube bending forming method and device.
For a long time, the handlebar moulding of bicycle, motor bike, perambulator, three-wheel vehicle etc., because of size, shape and style have nothing in common with each other, general handlebar make-up machine all can not adapt to this multifarious variation, normally every exploitation is a kind of type, will design two specialized equipments, and production site is big often, investment cost is big, the manufacturing that is designed into of slave unit need be chronic, and the renovation of handlebar moulding is restricted.
As Britain is based on the single head pipe bending machine, and making a light roadster handlebar needs four procedures, because asymmetric, still need manually to be proofreaied and correct on anchor clamps, this pipe bending machine can only adapt to the possibility of different wall and four, five kind of moulding, but makes complicated, efficient is low, the labour intensity height.
Japan serves as main processing with the double end hydraulic efficiency pipe bender, it is divided into and once curves type and secondary curves type, once curving type is with the punching type moulding, it is by two oil cylinder bonded assembly bending of the hands that secondary curves type, keep the briquetting roller of certain width between centers to rotate to an angle around two, make pipe along the briquetting roller brake forming, this pipe bending machine is than single head pipe bending machine advanced person, can two crooked simultaneously, symmetry might as well, but do not possess the general utility functions of multiple moulding, because the angle of bending of the hand swing is to be determined by the oil cylinder fixed journey system, two briquetting rollers and width between centers thereof are fixed again, therefore will be equipped with corresponding apparatus to the processing of type to difference.
Domestic bicycle trade, the use single head pipe bending machine that has, but most of punching type pipe bending machine that uses, this pipe bending machine is fast except that speed, the high shortcoming of output is many, at first being pipe is easy to generate plastic deformation man-hour adding, and secondly is that body is huge, and moulding is single, the control system that does not possess multiple moulding will realize that multiple moulding is very difficult.
The objective of the invention is to provide and to adapt to a whole set of control apparatus and the method that multiple handlebar moulding is had in order to overcome above-mentioned shortcoming.
Method of the present invention is by a whole set of control system, be that handlebar width between centers control apparatus, handlebar bend angle control apparatus, handlebar bending spring control apparatus, handlebar grip arrangement for adjusting height and handlebar are the parallactic angle control apparatus, respectively to bicycle handle bar's eight involved variable parameters in once bending the curved modeling process of moulding and secondary, promptly subordinate width between centers A
1, bend angles alpha
1, subordinate center radius R
1, width between centers A, handle height H, angle of bend φ on the handle
1, center radius R and handgrip parallactic angle φ on the handle
2Deng regulating, realize the moulding of various style handlebars.
Concrete grammar is in once curving the type process, by handlebar width between centers control apparatus, to regulate the spacing of two briquetting rollers, width between centers A under the realization handlebar
1Variation; By handlebar bend angle control apparatus, regulate the angle of bending of the hand rotation, realize bent angle alpha
1Variation; By handlebar bending spring control apparatus, the briquetting roller of transposing different-diameter, the distance of regulating briquetting roller center and bend pipe center simultaneously realizes subordinate center radius R
1Variation; Curve in the type process at secondary,, regulate the spacing of two briquetting rollers, realize the variation of width between centers A on the handlebar,, regulate the angle of bending of the hand rotation, realize angle of bend φ by handlebar bend angle control apparatus by handlebar width between centers control apparatus
1Variation, by handlebar bending spring control apparatus, the briquetting roller of transposing different-diameter, the distance of regulating briquetting roller center and bend pipe center simultaneously, realize the variation of center radius R on the handle, by the handlebar grip arrangement for adjusting height, regulate the fixedly anchor clamps at handlebar center, i.e. height between support platform and two the briquetting roller centers, realize the variation of handle height H, the parallactic angle control apparatus, regulate the axis angle of two briquetting rollers by handlebar, realize handgrip parallactic angle φ
2Variation.
According to the present invention, this device comprises a whole set of system's control apparatus that is had in bending forming machine and the secondary bending forming machine, one time bending forming machine has a handlebar width between centers control apparatus, a handlebar bend angle control apparatus and a handlebar bending spring control apparatus; The secondary bending forming machine has a handlebar width between centers control apparatus, a handlebar bend angle control apparatus, a handlebar bending spring control apparatus, a handlebar grip arrangement for adjusting height, a handlebar grip arrangement for adjusting height and a handlebar are the parallactic angle control apparatus.
