Special multi-roller extruder for raindrop wire separation pipe

Abstract

The invention relates to a special multi-roller extruder for a raindrop wire separation pipe. The special multi-roller extruder is used for extruding a round pipe to form the raindrop wire separationpipe; the section of the raindrop wire separation pipe consists of a large arc section and a gradual shrinkage section; and the gradual shrinkage section consists of a gradual shrinkage wire separation pipe straight section, and a small arc section connected to a shrinkage end of the wire separation pipe straight section. The extruder comprises a frame, and a lower roller set, an upper roller set,a lower roller driving mechanism and a pressing mechanism arranged on the frame 1; the round pipe is used as a raw material of the wire separation pipe; and through multiple times of work of a molding roller with an included angle of the straight section of a molding groove from big to small, the round pipe is extruded as a clamping shape to form a raindrop section. Compared with the prior art, aworking roller is small in diameter, so that replacement is convenient, the auxiliary time is reduced, and the productivity is improved; the working roller is high in effective utilization rate; anda rolling mill is small in size and low in weight.

Description

technical field [0001] The invention relates to a multi-roll extruder, in particular to a multi-roll extruder dedicated to a raindrop-shaped wire splitting tube. Background technique [0002] The number of work rolls of the rolling mill used in the rolling of components is small, and the work rolls are structurally constrained by the gap between the two backup rolls, and the diameter of the work rolls is limited. With the development of technology, there are more and more types of multi-roll rolling mills, and the precision of rolling is getting higher and higher. The diameter of the rolls is reduced and the stiffness of the rolls is increased. However, multi-roll mills are mainly used for rolling high-strength metal and alloy thin strips, rolling high-precision strips, and rolling ultra-thin strips, and there is no rolling mill for rolling components with complex cross-section designs. Based on actual needs, the present invention proposes a multi-roll special rolling mill ...
