Engaging element forming device in zipper string continuous manufacturing machine

Abstract

Disclosed is an engaging element forming device in a continuous manufacturing machine for zipper strings, in which a forming die can be used repeatedly. The head of the engaging element blank (WA) is formed into a mountain shape by the forming die (4) arranged on the first ram (40) moving in the front-rear direction and the forming punch (5) moving up and down, wherein the above-mentioned forming Die (4) is to have the polyhedron shape of a plurality of surfaces (62), has on each surface (62) the recessed part (63) that head is shaped, with the head shaped recessed part (63) of one surface (62) and above-mentioned The forming die (4) can be freely replaced on the mounting portion (50) of the above-mentioned first ram (40) in such a way that the forming punch (5) is opposite, so that the forming die (4) can be used equivalent to the above-mentioned The number of times of the surface (62).

Description

technical field [0001] The present invention relates to an engaging element forming device provided on an engaging element forming implant in a continuous fastener stringer manufacturing machine. Background technique [0002] Conventionally, as a fastener stringer continuous manufacturing machine, as disclosed in Patent Document 1, there is known a fastener stringer continuous manufacturing machine having a forming implantation portion of an engaging element, an intermittent A feeding device for the metal wire for engaging elements that is fed to the forming implant part, a fastener tape feeding device that intermittently feeds the fastener tape to the forming implant by feeding out the fastener stringer, etc. [0003] As the above-mentioned metal wire for engaging elements, a long metal wire having a circular cross-section is formed by a plurality of rolls into a substantially Y-shaped cross-section having a head and a pair of legs. [0004] The forming implant part of the...

AI Technical Summary

Problems solved by technology

[0011] In the above-mentioned conventional engaging element forming device, the concave part for forming the head of the forming die may be worn or damaged. die, and install the new forming die on the ram

[0012] Like this, in the meshing element forming device in the conventional zipper stringer continuous manufacturing machine, prepare a plurality of forming dies in advance, because when the head shaping recessed portion of this forming die is worn or damaged etc. every time, it is necessary to replace it with a new one. Therefore, it is necessary to prepare multiple forming dies, and the cost is high
