Abstract

A die with alignment mechanism includes a die including a through-hole through which a traveling wire travels, a bearing member for rotationally moving the die in a circumferential direction of the traveling wire, and a movable member that moves the die so that a central axis of the through-hole is aligned with a travel direction of the traveling wire without inhibiting the rotational movement of the die produced by the bearing member when the travel direction changes in a direction orthogonal to the travel direction.

First claim

What is claimed is:

1. An enameled wire manufacturing method, comprising:
applying a coating material around a traveling wire; and
adjusting a thickness of the coating material applied around the traveling wire by using a die with alignment mechanism that comprises a die comprising a through-hole through which a traveling wire travels, a bearing member for rotationally moving the die in a circumferential direction of the traveling wire, and a movable member that moves the die so that a central axis of the through-hole is aligned with a travel direction of the traveling wire without inhibiting the rotational movement of the die produced by the bearing member when the travel direction changes in a direction orthogonal to the travel direction,
wherein the movable member comprises a main body and a movable portion, the main body comprising a recessed portion for fitting the bearing member and a hole portion provided on a bottom surface of the recessed portion to allow a portion of the die to penetrate through, and the movable portion being arranged on a forward side of the main body in the travel direction to move the main body in a direction orthogonal to the travel direction of the traveling wire,
wherein the die has one end face and another end face opposite thereto and comprises a flange portion including the one end face and a stem portion including the other end face and extending from the flange portion, and the though-hole is provided from the one end face to the other end face, and
wherein the die with alignment mechanism further comprises a guide member that is arranged to be in contact with the movable member and comprises a guide surface for guiding the movable member.

2. The enameled wire manufacturing method according to claim 1 , wherein the bearing member comprises a bearing portion for rotationally moving the die in the circumferential direction of the traveling wire and has an annular outer shape.

3. The enameled wire manufacturing method according to claim 1 , wherein the die with alignment mechanism comprises a receiving member that is arranged between the movable member and the die and comprises a raised portion protruding in the travel direction of the traveling wire and abutting against the bearing member.

4. The enameled wire manufacturing method according to claim 1 , wherein the movable portion of the movable member comprises rollers.

5. The enameled wire manufacturing method according to claim 1 , wherein the movable portion of the movable member comprises ball rollers.
