ならずポンチ２との面合せ作業に多大の工数を要する。Conventionally, when punching and bending a thin plate, a thin plate (workpiece) that has been formed into a predetermined shape by drawing, etc.
Place it on the upper surface of the lower die (punch), and in this state upper ffi'
This is done by lowering the workpiece and punching and bending the outer circumference of the workpiece.
Cast metal is generally used for the workpiece when the upper mold is raised after shearing and shearing. However, if the clearance between pad 1 and punch 2 is uneven as shown in Figure 1, In areas where the clearance for the punch 1 is locally narrow, such as the area A, the product 3 is likely to be damaged. On the other hand, in order to make the clearance between the pad 1 and the punch 2 completely uniform, the bulging portion like the part A must be cut and removed many times, and the face-to-face operation with the punch 2 requires a large amount of man-hours.

本発明全完成した。The inventors of the present invention came up with the idea that all of the above problems could be solved if it were possible to form a @ film in the shape of the sample plate on the surface of the pad, and after conducting their own tests and research, they completed the present invention. did.

とを特徴とするものである。That is, the method of manufacturing the press-type pad surface of the present invention involves applying a slowly volatile organic solvent-based paint to the surface of a cast pad, drying it, and then pressing it onto a sample plate.1. , the surface shape of the pad is made to follow the surface shape of the sample plate.

は剥離のない強い接着力を有していることが望ましい。In order to make the surface shape of the pad imitate the surface shape of the sample plate, it is necessary to select a paint that allows the dried coating on the pad to retain its viscosity and plasticity for some time. Further, it is desirable that this recoating J has strong adhesive strength that does not dissolve in other solvents or peel off.
本発明者等は、これらの条件を備えた塗料をめて試験し
た結果、緩挿発性の有機溶媒例えばトルエン系の溶剤に
相溶性のある塗料が上記目的に適うことを見出した。As a result of testing paints that meet these conditions, the present inventors have found that paints that are compatible with slowly evolving organic solvents, such as toluene-based solvents, are suitable for the above purpose.

Then press it to the punch 2 and keep it for 3 minutes.The gap between the sample plate 2 and the sample plate 2 will be crushed and the second
As shown in FIG. 3, a pad surface 6 having a uniform clearance with respect to the punch 2 is formed. In this way, once the pad surface 6 is formed on the surface of the pad 1, the load is not concentrated on a local part of the product, and a product without scratches can be obtained even after repeated use.

It is possible to mass produce products with good quality and no damage while reducing costs.
