Continuous cladding method and device of obtuse angle flowing channel

Abstract

The invention discloses a continuous cladding method of an obtuse angle flowing channel. The continuous cladding method comprises the following steps that: a, under the compaction of a compaction wheel, a blank enters an extruding cavity through a friction force between a rotary extruding wheel groove and the blank; b, when the blank advances to a baffle block, the blank enters an extruding cavity feeding hole, wherein the center line of the extruding cavity feeding hole is in a chord line direction of an extruding wheel in a non-radius direction; and c, a metal flowing channel forming the obtuse angle with the cavity feeding hole is arranged at the tail end of the extruding cavity feeding hole, a cladding forming metal containing cavity is arranged at the tail end of the metal flowing channel, a female die and a male die are arranged at the tail end of the cladding forming metal containing cavity, a metal flow velocity splitter is arranged between the female die and the male die, a product is extruded through a circular seam formed by the female die and the male die, a core wire is transferred in through a center circular hole in the male die, and a cladding metal is extruded to form a cladding layer outside the core wire. According to the continuous cladding method, by adopting the blank and through one group of flowing channels with obtuse angles of more than 95 DEG, the metal is extruded to form different cable cladding products through the dies.

Description

technical field [0001] The invention relates to a continuous coating method of an obtuse angle flow channel. Background technique [0002] The feed hole on the traditional continuous coating tool is in the radial direction of the extrusion wheel. Sometimes in order to improve the strength of the block, the direction of the feed hole will be offset by a certain angle. The center line of the cavity feed hole and the extrusion wheel The angle β of the point tangent line is 90° or an acute angle less than 90°. The advantage of this is that the block is in a good stress state and can improve the service life of the block. The disadvantage is that the temperature of the block is high and the extrusion force Big. [0003] In the traditional continuous coating method, after the metal billet enters the cavity of the cavity, the metal billet needs to turn a 90° right-angle bend in the opposite direction to the extrusion wheel, and enter the forming mold; continuous equal-channel angu...
