め装置の体裁に大きな影畳を与える。Conventionally, jack caps have been made either by cutting a round bar-shaped material or by drawing out a metal plate with multiple drawings. Although the cutting process can produce a good-looking and durable product, it is expensive due to the high material and additional costs, so it is only applied to jacks used in some limited fields. Jack Kawaguchi gold mine made by drawing process is inexpensive and widely used for general consumer use. By the way, as is well known, the drawing process involves forming a cup-shaped body through multiple stamping processes and cutting off the bottom of the cup-shaped body to form a cylindrical body. Fine irregularities (generally called arabic) are formed on the surface, so even if plated, it lacks luster and is unsightly. The jack is often attached to the outside of the device, and when the jack is attached to the device, the inner circumferential wall of the jack base is clearly visible from the outside, giving a large impact on the appearance of the device.
この発明の目的は絞シ加工と同じ程度の製造コストで、
然も絞り加工よシ体裁のよいジャック用口金を提供でき
る口金の製造方法を提案するにある。The purpose of this invention is to achieve the same manufacturing cost as drawing process,
However, the object of the present invention is to propose a method of manufacturing a jack cap that can provide a jack cap with a better appearance than the drawing process.
この発明では金属板に小孔を形成し、この小孔を中心と
して円筒体を形成し、この円筒体の一端側にフランジ部
を形成するようにし九ものである。In this invention, a small hole is formed in a metal plate, a cylindrical body is formed around the small hole, and a flange is formed at one end of the cylindrical body.
以下にこめ発明の一実施例を図面を用いて詳細２． １゛説明する。An embodiment of the invention will be described below in detail with reference to the drawings. 1. Explain.
第１図にこの発明による口金の製造方法の工程を示す。FIG. 1 shows the steps of the method for manufacturing a cap according to the present invention.
図中１は例えば銅板のような金属板を示す。この発明で
は金属板ｌに小孔２を形成すると共に、この小孔２を中
心にポンチ３によって所定の直径と所定の筒長を持つ円
筒体４を形成する。In the figure, 1 indicates a metal plate such as a copper plate. In this invention, a small hole 2 is formed in a metal plate 1, and a cylindrical body 4 having a predetermined diameter and a predetermined length is formed using a punch 3 around the small hole 2.
このポンチ３による打出加工は一工程で行なわれる。更
にポンチ３に祉ポンチ３の上部に打抜用刃５を有し、こ
の打抜用刃５によって金属板１を円形に打抜く工程も同
時に行なわれる。この打抜により円筒体４は金属板１か
ら切離され、第２図に示すように円筒体４の一端に７ラ
ンジ部６を持つジャック用口金７を得ることができる。This punching process using the punch 3 is performed in one step. Further, the punch 3 has a punching blade 5 on the upper part of the punch 3, and the process of punching out the metal plate 1 into a circular shape is also performed at the same time with the punching blade 5. By this punching, the cylindrical body 4 is separated from the metal plate 1, and a jack base 7 having seven flange portions 6 at one end of the cylindrical body 4 can be obtained as shown in FIG.
この発明の特徴は金属板１に小孔２を形成し、この小孔
２を中心に円筒体４を一工楊で打出加工する点である。A feature of the present invention is that a small hole 2 is formed in a metal plate 1, and a cylindrical body 4 is stamped using a single punch with the small hole 2 as the center.
小孔２を形成してその小孔２を中心に打出加工すること
により一工程で所定の直径と所定の筒長を持つ円筒体４
を得ることができる。By forming a small hole 2 and punching around the small hole 2, a cylindrical body 4 having a predetermined diameter and a predetermined length is produced in one step.
can be obtained.
一工程で円筒体４を形成できることから、この発明の製
造方法によれば口金７の内壁面はア２どの発生がなく、
−面状に作ることができる。よってメッキ仕上げするこ
とにより光沢のある体裁のよいジャック用口金を得るこ
とができる。Since the cylindrical body 4 can be formed in one step, according to the manufacturing method of the present invention, the inner wall surface of the cap 7 is free from A2 and cracks.
-Can be made into a planar shape. Therefore, by plating it, a shiny and good-looking jack cap can be obtained.
上述し九ようにこの発明によれば、絞り加工より少ない
工程数でジャック用口金を得ること〃；できるから絞り
加工よシむしろ安価に作ること２＞Ｅできる。然も絞り
加°工より体裁のよい、どちら力為と隻えば割出し加工
によって作られた口金に近い体裁の口金を得ることがで
き、安価で体裁のよいジャックを得ることができる。As described above, according to the present invention, it is possible to obtain a jack cap with a fewer number of steps than drawing. However, it is possible to obtain a cap that is more aesthetically pleasing than the drawing process, and is similar in appearance to a cap made by the indexing process, and it is possible to obtain a jack that is inexpensive and has a good appearance.
