Abstract

The invention provides a stamping device for fixing nuts on pipes, which is especially suitable for fixing nuts on pipes with small diameters, and can be easily automated. The punching device is provided with: an upper pedestal; a movable support body, which covers the pipe material outside to support the pipe material; a nut accommodating recess, which is arranged on the upper end of the lower mold part, and the lower mold part is arranged on the movable support body. The piston of the hydraulic cylinder for pressurizing the lower mold at the front end of the hydraulic cylinder protrudes upward from the hydraulic cylinder housing and moves up and down; the lifting device that can move up and down slightly lifts the front end of the movable support body The posture abutting support; the stopper that can move up and down; the riveting mold that becomes the upper mold, which is installed on the upper mold support that can move freely up and down along the guide column, and is configured to be able to be connected with the lower mold part. freely move up and down on the same axis; and a hydraulic cylinder for pressurizing the upper mold, which is installed on the upper pedestal, and pressurizes the riveting mold downward.

Description

technical field [0001] The present invention relates to a punching device for fixing a nut on a pipe material, especially a metal square pipe (corner pipe). Background technique [0002] A device for fixing a nut on a pipe is known from Patent Document 1: a piercing nut is used to fix the nut on the inner wall of a metal square pipe, so that it can be screwed from the outside of the square pipe, wherein the so-called The piercing nut is made by punching the metal plate by the nut itself, and at the same time caulking the pierced opening peripheral part and pressing it into the groove provided on the side wall surface of the nut, so as to fix the nut on the metal plate . [0003] The device disclosed in the above-mentioned Patent Document 1 is a manual type, has a background of the times, and has not been put into practical use until now. [0004] Patent Document 1: Japanese Patent Publication No. 53-16394 (Patent No. 0943112) Contents of the invention [0005] The prese...
