Description

Flexible connecting core for processing roller arc of tubular beam

Technical Field

The utility model relates to a core, in particular to a flexible connecting core for processing a pipe beam roller arc.

Background

After the closed cavity tube beam has a certain curvature, the surface of the product is extruded to have quality defects such as folds and the like, and in order to improve the problem, a core is generally penetrated into a cavity of the tube beam to support the inner surface of the product so as to inhibit the folds. The core structure commonly used at present consists of a plurality of groups of core sections, the core sections are connected through pin shafts, each core section can rotate relative to the pin shafts, and the core adapts to the shape of a cavity in the arc forming process to achieve the effect of supporting the surface of a product and inhibiting wrinkles. The problems with such conventional cores are: the core sections are connected by pin shafts, can only rotate relatively and cannot move relatively, the rigidity between the core sections is high, the core sections cannot be well attached to the cavity in the arc forming process, and the capacity of adapting to the cavity is limited. Therefore, a core with high flexibility needs to be designed, so that the core section is fully attached to the inner surface of the cavity in the arc forming process, and the purpose of fully inhibiting wrinkles is achieved.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems in the prior art and provides a flexible connecting core for roller arc machining of a tubular beam, which has high degree of freedom between core sections and good laminating property between the core sections and a tubular beam cavity.

The problem of the utility model is realized by the following technical scheme:

the utility model provides a flexonics core for processing of pipe beam roller arc, includes the core festival that the several connects gradually through wire rope, the core festival comprises last core festival and lower core festival, goes up the mutual corresponding setting wire rope groove that sets up respectively on the butt joint face of core festival, lower core festival, is as an organic whole by pin and screw connection between the upper and lower core festival, and wire rope passes the wire rope groove after upper and lower core festival closes and constitutes flexonics with each core festival.

The steel wire rope is in interference fit with the steel wire rope groove.

The flexible connection core for the roller arc processing of the pipe beam is characterized in that the butt joint surface of the upper core section is convex, the butt joint surface of the lower core section is concave, and the butt joint surfaces of the upper core section and the lower core section are in convex-concave involution.

The flexible connection core for processing the roller arc of the pipe beam is characterized in that two steel wire rope grooves are respectively formed in the butt joint surface of each upper core section and each lower core section.

Above-mentioned a flexonics core for processing of tubular beam roller arc, the core head end sets up head end core festival, and head end core festival is equipped with the connecting block, is equipped with the connecting pin shaft hole on the connecting block.

The utility model improves the problem that the traditional core section cannot be well attached to a tubular beam cavity, and designs a flexibly connected core.
