A rotary forging heat pipe shrinking die head

Abstract

The invention discloses a rotary forging heat pipe reducing die head. A spindle is of a hollow cylindrical structure; one end of the spindle is connected with a belt wheel; the other end of the spindle is arranged in a shell; the front end of the spindle is provided with an end face slot provided with three or four openings at the front end of the spindle along the circumference; dies are mounted in the end face slot at the front face of the spindle; each opening of the end face slot is provided one die; the centers of the multiple dies form a cylindrical hollow cavity; a hammer head is mounted at the outer side of the dies and is a lump-like extending part; the outer side of the hammer head is an arc face; a sleeve is arranged at the periphery of the front end of the spindle; a rolling post keeping frame is arranged in the annular space between the sleeve and the outer diameter of the spindle and is provided with multiple blind holes along the peripheral direction; rolling posts are a cylinder-like part and are embedded in the blind holes in the rolling post keeping frame. The rotary forging heat pipe reducing die head solves the problems of large die head consumption, large noise and difficult maintaining in the heat pipe reducing process, and can meet the process demands of large diameter and large hole shrinkage.

Description

technical field [0001] The invention relates to a heat pipe, in particular to a rotary forging heat pipe shrinking die head, which belongs to the technical field of heat pipe shrinkage processing. Background technique [0002] A heat pipe is a component that utilizes the phase change of the working fluid in a closed cavity to achieve efficient heat transfer. In the current structure of the die head of the common shrinking machine, the position accuracy of the roller is not high, the shaking is large, it is not easy to take out, replace or maintain, and it increases the noise generated during work, which is easy to produce defective products. Tube efficiency is low. The grease of the tapered roller bearing on the main shaft is easily polluted by debris from the mold, and it is not easy to replace the grease. The main shaft is in direct contact with the mold, resulting in high wear and low life. Contents of the invention [0003] In order to solve the problems of low roll...
