Embodiment Construction

[0057] Embodiments of the present invention will be described below with reference to the drawings.

[0058] Figure 1 to Figure 4 It shows the punching device for fixing and installing nuts on the pipe material of the present invention, and the punching device is used in the metal square pipe 60 described later (refer to Figure 5 , Figure 6 ) on the fixed installation punching nut 61 from the inside. The frame 1 of the press machine is configured to support the upper base plate 3 by two vertical guide columns 4 and 4 juxtaposed on the front end side of the lower base plate 2 and a rear side wall 5 erected on the rear end side.

[0059] On the lower base plate 2, a lower form 6 composed of a prismatic elongated member extends in the front-rear direction and is arranged approximately horizontally; It can move freely in the vertical direction perpendicular to the axis of the die 6 .

[0060]The lower mold 6 has an inclined guide surface 8 at the front end, and a short rect...

Abstract

A press for attaching nuts to pipes has a lower holder ( 6 ) fitting in and holding a pipe ( 60 ). A basal portion of this holder supported on the rear part of a lower base ( 2 ) moves up and down, and its forward portion extends to the front part of a lower base. Lifters ( 30 ) bear against and support the forward portion so as to keep it lifted a slight distance. Stoppers ( 31 ) bear against and support an intermediate region of the holder to be lifted a slight distance, and also bear against an end of the pipe ( 60 ) and retaining it at a prescribed position. A nut feed passage ( 10 ) extends in an outer surface of the lower holder from its basal to forward portion, and a nut pusher ( 14 ) is disposed in the forward portion. A cam rod ( 21 ) inserted in the lower holder ( 6 ) has a frontal oblique cam surface ( 22 ) for driving the pusher ( 14 ) to a nut releasing position ( 12 ), and a cam actuating means ( 25 ) is for the rod. An upper holder ( 3 ) moves in a direction perpendicular to the lower holder ( 6 ), a caulking die ( 47 ) is carried by the upper holder ( 3 ), and a die driving means ( 50 ) is for the caulking die, such that the press is rendered easy to automate.

Description

technical field [0001] The invention relates to a stamping device for fixing nuts on the inner side of pipes, especially metal square pipes. Background technique [0002] Patent Document 1 discloses a punching device for fixing a nut on a pipe, which can use a piercing nut (pierce nut), fix it on the inner wall surface of a metal square pipe, and thread it from the outside of the square pipe. Fastening, and the so-called punching nut is that the nut itself stamps the metal plate, and at the same time, the stamped opening peripheral part is caulked and pressed into the groove provided on the side wall of the nut, so that the nut is fixedly installed on the metal plate . [0003] The device described in the above-mentioned Patent Document 1 is a manual type, and has not been put into practical use until now due to the background of the times. [0004] [Patent Document 1] Japanese Patent Publication No. 53-16394 Contents of the invention [0005] An object of the present i...
