Abstract
The utility model discloses a tubeless wheel rim rolls together rolls shape mould, roll on including the shape mould and with on roll and roll shape mould, its characterized in that under the shape mould matched with: roll on and be equipped with rim preforming portion in proper order on the shape mould, go up 15 preforming portions of rim, go up a rim installation face preforming portion, last rim tank bottom preforming portion, roll shape mould correspondence and be equipped with down rim preforming portion, 15 preforming portions of rim, a rim installation face preforming portion, lower rim tank bottom preforming portion down down. Tubeless wheel rim roll the shape mould together, during through one shaping of rim, carry out taking shape in advance of rim, 15, installation face and tank bottom, has effectually alleviateed follow -up two, three and has rolled the high problem of shape load, promoted production efficiency, be applicable to the manufacturing of 17.5 " to the high -strength steel material rim between 24.5 ".
Description
Technical field
The utility model relates to rim for automobile wheel field, and what particularly a kind of inner tube-free wheel rim rolled together rolls shape mould.
Background technology
The material of Automobile steel ring wheel rim commercially a large amount of use at present, its tensile strength is all between 330-380MPa.Wheel rim is by dull and stereotyped billot through volume circle-butt welding-roll the series of processes such as shape-expansion to process, and this wheel rim matches with radial-ply tyre and forms confined space and form inflatable chamber, forms support member, reach tubeless requirement together with spoke.Wheel rim manufacturing process is comparatively complicated, and its core rolls shape, wherein rolls shape and mainly comprises three roads and roll shape (being called for short three roads to roll).The design of roll die then mainly will be followed one and roll and center, two be rolled into the principle design that shape, three rolls sizing.
Along with growing with each passing day to the light-weighted demand of steel ring in domestic and international market especially overseas market, meanwhile domestic steel mill tries to be the first and develops the manufacture of the material of tensile strength between 490-600MPa for tyre rim.Under this situation, old low-intensity material wheel rim roll the demand that shape technique can not be satisfied with high-strength steel material forming process: old shape technique of rolling is when producing for high-strength steel material wheel rim, occurred that debug difficulties, length consuming time, debugging percent defective are high, it is unstable to produce, equipment load is high and caused maintenance rate growing concern.
Summary of the invention
For the problems referred to above, what the purpose of this utility model was to provide a kind of inner tube-free wheel rim to roll together rolls shape mould, be applicable to the different wheel rims that the employing high-strength steel material between 17.5 " to 24.5 " manufactures, solve and roll shape sideslip, debug length consuming time, high, the equipment load high problem of debugging percent defective, improve production efficiency.
For achieving the above object, the technical scheme that the utility model proposes is: what a kind of inner tube-free wheel rim rolled together rolls shape mould, comprise roll shape mould and with described on roll shape mould and match down and roll shape mould, it is characterized in that: roll on described on shape mould and be provided with preformed portion at the bottom of rim preformed portion, preformed portion, upper wheel rim 15 ° of faces, upper wheel rim installed surface preformed portion, upper rim gutter successively; Roll shape mould correspondence under described and be provided with lower rim preformed portion, preformed portion, lower wheel rim 15 ° of faces, lower wheel rim installed surface preformed portion, lower wheel rim bottom land preformed portion.
Adopt technique scheme, what inner tube-free wheel rim described in the utility model rolled together rolls shape mould, when being rolled into type together by wheel rim, carry out the preform of wheel rim, 15 ° of faces, installed surface and bottom land, effectively alleviate follow-up two roads, three roads roll the high problem of shape load, correct for sideslip problem before and after when rolling shape, improve production efficiency, be applicable to the manufacturing of the high-strength steel material wheel rim between 17.5 " to 24.5 ".
Accompanying drawing explanation
Fig. 1 be inner tube-free wheel rim described in the utility model roll together roll shape mould schematic diagram.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, what inner tube-free wheel rim described in the utility model rolled together rolls shape mould, comprise, comprise roll shape mould 10 and with described on roll shape mould and match down and roll shape mould 20, roll on described on shape mould 10 and be provided with preformed portion 104 at the bottom of rim preformed portion 101, preformed portion, upper wheel rim 15 ° of faces 102, upper wheel rim installed surface preformed portion 103, upper rim gutter successively; Roll shape mould 20 correspondence under described and be provided with lower rim preformed portion 201, preformed portion, lower wheel rim 15 ° of faces 202, lower wheel rim installed surface preformed portion 203, lower wheel rim bottom land preformed portion 204.During concrete use, the shape mould that rolls adopting inner tube-free wheel rim described in the utility model to roll together carries out wheel rim and is shaped together, completes wheel rim, 15 ° of faces, installed surface bottom land preform.Wherein the preform of wheel rim adds deviation-correcting function, and reserved material ensures Reducing thickness simultaneously; 15 ° of face preforms adopt minus deviation angle phase shapes; Bottom land preform adopts increase to roll shape groove depth and use large R angle, reduces Reducing thickness; Effectively can alleviate follow-up two roads, three roads roll the high problem of shape load, improve production efficiency, be applicable to the manufacturing of the high-strength steel material wheel rim between 17.5 " to 24.5 ".
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
