Embodiment Construction

[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0017] refer to figure 1 with figure 2 Shown, the production technology of a kind of powder metallurgy copper infiltrating parts, comprises the following steps:

[0018] Step 1) According to the technical characteristics of powder metallurgy, it is divided into the first part 1 and the second part 2 to be formed separately. Part 2 can be formed one by one;

[0019] Step 2) Select materials reasonably according to the strength requirements of the parts, and determine the matching dimensions of the first part 1 and the second part 2, and then establish the size of the forming mold according to the change rate of the powder material;

[0020] Step 3) Assemble and pre-sinter the first part 1 and the second part 2, and then carry out formal sintering of copper infiltration, and the sintering conditions are all standard sintering condi...

Abstract

The invention discloses a production process of copper-infiltrated parts by powder metallurgy. The production process includes the steps of splitting dies reasonably according to part features to allow the parts to be conveniently formed by powder metallurgy technology; reasonably selecting raw materials according to use intensity and material features, and fully utilizing sintering and copper infiltrating for welding to enable the parts to be satisfactory. The products produced by the production process are stable in quality, and operating efficiency is higher. Cycle and cost of the production process are greatly lower than the traditional machining ways.

Description

technical field [0001] The invention relates to a production process of powder metallurgy copper-infiltrated parts. Background technique [0002] The two production processes of sintering copper infiltration and sintering welding technology in ordinary powder metallurgy technology are quite common at present, and the other two production processes are not efficient and the quality is not stable. However, if the two are combined, it can not only make up for the shortcomings of the simple structure of the copper infiltrated parts and the difficulty of sintering and welding, but also improve the work efficiency and product quality. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, and provide a production process of powder metallurgy copper-infiltrated parts, which is more convenient and efficient. [0004] In order to achieve the above-mentioned technical purpose and achieve the above-mentioned techni...
