〔発明の背景と目的〕
本発明は長尺条の打抜方法、特にＩ ＣＩＪ−ドフレー
ムの打抜方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Background and Objects of the Invention] The present invention relates to a method for punching out long strips, and particularly to a method for punching ICIJ-deframes.
従来よシ行われているＩ ＣＩＪ−ドフレームの製造方
法としては、長尺条の素材を用意し、との長尺条を順送

用されている。The conventional manufacturing method for ICIJ-do frames involves preparing a long strip of material, feeding the long strip to a progressive mold, cutting it into a predetermined chisel turn, and then A method is adopted in which the required parts of the long strip are partially plated with precious metal, or a long strip material is partially plated with precious metal in advance and then fed into a progressive die and punched into a predetermined pattern.

生じたりする問題があった。By the way, in the above-mentioned conventional method, before feeding the long strip to the progressive die and forming the predetermined punching and ξ turns, a hole (ξ) is punched into a predetermined position of the long strip (6).
2) (see Figure 1), then insert this pilot hole (2) into a pilot hole (3) protruding from one of the molds.
), the long strip (6) is sequentially fed while being picked up by the long strip (
6) f: 10 to 20 while positioning at each position
A predetermined pattern was formed through several punching processes. In this case, the insertion of the pilot hole into the pilot hole is performed intermittently depending on the number of punching processes, and at this time, there may be a misalignment between the pilot hole and the pilot pin due to dimensional errors, If there is a slight deviation in the length of the sequential feed of the strips, there is a problem that the product may be damaged or deformed (bent).
本発明は上記の事情に鑑みなされたものであり、その目
的は・ξイロット穴に対する・ξイロットピンの位置決

防止することにある。The present invention has been made in view of the above circumstances, and its purpose is to prevent the occurrence of defective products as much as possible by accurately confirming the positioning of the ξ pilot pin relative to the ξ pilot hole.

て非接触的に行うことにある。The gist of the present invention is that in a method of punching and forming a predetermined ξ turn in a long strip using a progressive die, first, a Next, the pilot pin is inserted into the hole to fix the long strip, and then punched out with a punching die, i.e., the ξ pilot hole is detected by light, and the pilot pin is inserted into the pilot hole to fix the long strip, and then punched out with a punching die. The purpose of this technology is to confirm the positioning of objects using light in a non-contact manner.

4) and the lower mold (5) with a punch.
Set the long strip (6) punched out from 2), use the phototube (7) instead of the pilot pin (3), and confirm the position of the ξ pilot hole (2), and make sure the light passes through it. If the size of the area is detected by the original sensor (8) and an abnormality is detected (
For example, in the case of FIG. 4(b)), the press is immediately stopped. If it is confirmed that the pilot hole (2) is in the correct position by the above method, the pilot pin (3) is inserted into the ξ pilot hole (2) as in the conventional method. ) is fixed, then punched out using a punching die,
A predetermined punching pattern is formed on the long strip (6).
