本発明は、金属粉を充填した樹脂型表面に金属
を溶射する薄板プレス金型の製造法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for manufacturing a thin plate press mold by spraying metal onto the surface of a resin mold filled with metal powder.
薄板プレス用の金型として、ポリウレタン樹脂
に鋳鉄粉を充填した樹脂型を作り、これによつて
金型の耐摩耗性を高め、更にこの樹脂型表面に13
クロム鋼のような比較的高硬度の金属を溶射する
ことによつて表面のカジリを防止したものがあ
る。
As a mold for thin plate pressing, a resin mold is made of polyurethane resin filled with cast iron powder, which increases the wear resistance of the mold.
There are some products that prevent galling on the surface by thermally spraying a relatively hard metal such as chrome steel.
この樹脂金型は型素材としての樹脂に鋳鉄粉を
充填することによつて、表面に溶射する高硬度の
金属の型素材に対する密着性が得られ、これによ
つて樹脂金型への金属の溶射被覆層の形成が可能
になり、従来の金属製金型に比べ、製作のための
時間、工数を軽減せしめることができたものであ
る。 This resin mold is made by filling the resin as the mold material with cast iron powder, so that the high hardness metal that is thermally sprayed on the surface adheres to the mold material, which allows the metal to adhere to the resin mold. It is now possible to form a thermally sprayed coating layer, and the manufacturing time and man-hours can be reduced compared to conventional metal molds.
しかしながら、金型の素材そのものが樹脂を基
材とするものであるため、金型表面へ溶射される
硬質金属の樹脂素材との密着性は充分ではなく、
溶射金属の種類、厚み、溶射条件に制限を受ける
ことになり、金属素材による金型と比較して、強
度的に劣り、このためプレス加工に制限を受ける
という問題があつた。
However, since the mold material itself is based on resin, the adhesion of the hard metal sprayed onto the mold surface with the resin material is not sufficient.
There are restrictions on the type, thickness, and spraying conditions of the sprayed metal, and the strength is inferior to molds made of metal materials, which poses a problem in that press working is limited.
本発明の目的は、上記の樹脂金型の製造におい
て金型表面に溶射する硬質金属の金型生地への密
着性を改善して、高硬度、高融点物質のより厚み
の大きい溶射被覆層の形成を可能にして従来の金

を可能にするものである。 The purpose of the present invention is to improve the adhesion of the hard metal sprayed onto the mold surface to the mold fabric in the production of the above-mentioned resin molds, and to create a thicker thermal spray coating layer of high hardness and high melting point material. This makes it possible to manufacture molds with strength equal to or greater than conventional molds.
上記目的は、金型表面の高硬度溶射被覆層を形
成するに当たつて、樹脂中に混合する金属と表面
溶射層と相互に密着性の良い材料による下地層を
形成することによつて達成することができる。
The above objective is achieved by forming a base layer of a material that has good adhesion to the metal mixed in the resin and the surface sprayed layer when forming the high hardness sprayed coating layer on the mold surface. can do.
本発明においても、金型素材の樹脂としては、
従来金型の模型に使用されていたエポキシ樹脂を
使用することができるが、金属粉末との混合充填
のためには、取扱いが便利なポリウレタン樹脂が
好適に利用できる。 In the present invention, the resin for the mold material is
Epoxy resins conventionally used for mold models can be used, but for mixing and filling with metal powder, polyurethane resins, which are easy to handle, can be suitably used.
また、上記樹脂に混合すべき金属としては任意
のものが利用できるが、コストと耐酸化性と取扱
いの面から通常のアルミニウム粉や鋳鉄粉が使用
される。 Further, any metal can be used as the metal to be mixed with the resin, but ordinary aluminum powder or cast iron powder is used from the viewpoint of cost, oxidation resistance, and handling.
混合粉末としては、その上に溶射される下地層
に対してのアンカー効果を発揮せしめるために、
粒子径が100〜200μｍの多角形を有するものが望
ましい。また、混合金属の樹脂への混合量は、樹
脂型表面への金属粉の露出量を多くするために、
樹脂量に対して、重量比で20倍以上含有せしめ
る。 As a mixed powder, in order to exert an anchoring effect on the base layer that is thermally sprayed on top of it,
It is desirable that the particles have a polygonal shape with a particle diameter of 100 to 200 μm. In addition, the amount of mixed metal mixed into the resin should be adjusted to increase the amount of metal powder exposed to the resin mold surface.
Contain at least 20 times the amount of resin by weight.
しかしながら、本発明の場合には、金型表面に
形成される溶着硬質層は樹脂型素地の上に直接形
成されるものではなく、素地との密着性の良い下
地層が形成されるので樹脂材へ混合される金属粉
の量は従来に比し少なくて済み、また、金属粉を
含有した樹脂素材の調製を簡単に行なうことがで
きる。 However, in the case of the present invention, the welded hard layer formed on the mold surface is not directly formed on the resin mold base, but a base layer with good adhesion to the base is formed, so the resin material The amount of metal powder mixed into the resin material can be reduced compared to the conventional method, and a resin material containing metal powder can be easily prepared.
溶射による下地層の形成に当たつては、樹脂型
表面に露出する金属粉の態様にもよるが、通常の
防食用としてはAl或いはNi−Al合金の材料が好
適に使用でき、下地層の厚みは樹脂素材表面の金
属粉末の分布の状態と表面の硬質金属被覆層の状
態にもよるが、30〜50μｍの厚みに形成する。 When forming the base layer by thermal spraying, it depends on the state of the metal powder exposed on the surface of the resin mold, but Al or Ni-Al alloy materials can be suitably used for normal corrosion protection. Although the thickness depends on the state of distribution of the metal powder on the surface of the resin material and the state of the hard metal coating layer on the surface, it is formed to a thickness of 30 to 50 μm.
さらに、上記下地層の上に形成するトツプコー
テイング層のための硬質金属としては、任意の金
属、或いはセラミツクを用いることができるが、
通常の板金加工のためには、クロム或いはモリブ
デン含有鉄合金、高クロム鋼を用いる。 Further, as the hard metal for the top coating layer formed on the base layer, any metal or ceramic can be used.
For conventional sheet metal processing, chromium- or molybdenum-containing iron alloys, high chromium steels are used.
かかるトツプコーテイング層は、接着性の良好
な下地層が形成されているので任意の厚みに形成
できるが、通常の場合100μｍもあれば充分であ
る。 Since such a top coating layer has a base layer with good adhesive properties, it can be formed to any thickness, but 100 .mu.m is usually sufficient.

13Cr鋼の溶射被膜を有する試料Ｃを作成した。 In order to investigate the durability of such molds, we used a material made by mixing 50% by weight of Al powder with polyurethane resin.
The base layer consisting of Al and Ni-Al is 50 μm thick, respectively.
Test samples A and B were prepared by forming a top coating layer with a thickness of 100 μm by thermally spraying 13Cr steel powder thereon. Also, for comparison, the same thickness was prepared under the same conditions without forming any base layer.
Sample C having a sprayed coating of 13Cr steel was prepared.
