Problems solved by technology

[0002] In the past, weights for sports and fitness equipment (barbells, ordinary dumbbells, flat-head hexagonal dumbbells, dumbbells, etc.), some fitness equipment in the shape of balls, columns, and flakes, were cast with iron during manufacturing, and then post-processed Processing and other operations, this method has many production processes, is cumbersome, and has high cost; at present, iron powder is also used to process and form iron powder through powder metallurgy technology, but the process is not perfect, the quality of the produced products cannot meet the market demand, and the product quality is not firm.

Abstract

The invention relates to a production process of a sports fitness equipment counterweight. The production process of the sports fitness equipment counterweight comprises the following steps of 1) preparing raw materials: reduced iron powder accounting for 95 to 97 percent by weight of the total weight and a binder accounting for 3 to 5 percent by weight of the total weight; 2) mixing: stirring theproportioned iron powder and binder for 30 to 45 minutes at the temperature of 80 DEG C by a stirrer; 3) pressing: conveying the mixed raw materials into a powder pressing machine, and carrying out primary extrusion to form a product blank of the sports fitness equipment counterweight; 4) sintering and cooling: conveying the blank into a sintering furnace through a conveying belt so as to be sintered, and cooling after sintering and forming; and 5) conducting aftertreatment, and obtaining a finished product, wherein the sintered blank is subjected to one or a combination of subsequent electroplating, paint spraying, rubber coating, plastic dipping and TPU or CPU surface aftertreatment. The design is ingenious, the process is complete, and the product quality meets the market requirement.

Description

technical field [0001] The invention relates to the field of sports and fitness equipment processing, in particular to a production process for the counterweight of sports and fitness equipment. Background technique [0002] In the past, weights for sports and fitness equipment (barbells, ordinary dumbbells, flat-head hexagonal dumbbells, dumbbells, etc.), some fitness equipment in the shape of balls, columns, and flakes, were cast with iron during manufacturing, and then post-processed Processing and other operations, this method has many production processes, is cumbersome, and has high cost; at present, iron powder is also used for processing and molding by powder metallurgy technology, but the process is not perfect, the quality of the produced products cannot meet the market demand, and the product quality is not firm. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention proposes a production process of cou...
