[0003] The above-mentioned cast iron dumbbells, dumbbell plates, barbells, barbell plates, kettlebells or weight bars have high production costs. During the casting process, the size and weight of the products are not easy to control, the quality is not stable enough, the scrap rate is high, and the environment is polluted. high energy consumption
Dumbbells, dumbbell plates, barbells, barbell plates, kettlebells or weight bars filled with cement mixture are relatively cheap to produce, but because the density of the filler cement mixture is too small, dumbbells, dumbbell plates, barbells, barbells of the same weight specification Plates, kettlebells or weight bars increase the volume a lot, which is less convenient to use

Embodiment Construction
[0032] Such as figure 1 Shown is a kind of integral dumbbell, and the dumbbell head 11 and the dumbbell handle 12 are an integral body, which is formed by pressing a mixed material of mixed iron powder and binder. Of course, the dumbbell head and the dumbbell handle can be molded separately, such as figure 2 , the handle 22 is first prepared, and then pressed into shape with the dumbbell head 21, and the dumbbell head 21 is pressed into shape from a mixed material of mixed iron powder and binder; figure 2 Shown is a dumbbell which may also be a barbell. Such as figure 1 As shown, if the dumbbell head 11 and the dumbbell handle 12 are made into the same size, or the cylindrical shape has just become a kind of weight bar.
[0033] Such as image 3 Shown is a kettlebell, the kettlebell head 31 and the kettlebell handle 32 are integral, and are formed by pressing a mixed material of mixed iron powder and binder. according to figure 2 Of course, the kettlebell head 31 and ...

Abstract
The invention relates to a process for manufacturing dumbbell and barbell products. A material obtained by mixing iron powder and a binding agent is pressed into the shapes of barbell products, or the material obtained by mixing the iron powder and the binding agent is filled into a mould cavity produced according to the shapes of the barbell products, the expected shapes, dimensions and weights are achieved, and sizing, demoulding and air drying are carried out, thus specific products are obtained. The process is simple and easy to operate, the product cost is moderate, the density is moderate, and the produced products can substitute dumbbells, dumbbell discs, barbells, barbell discs, kettle bells or counter weight rods made by a mixture of cast iron and cement.
Description
Technical field: [0001] The invention relates to a manufacturing method of sports products, in particular to a manufacturing process of bar and dumbbell products. Background technique: [0002] There are mainly two types of manufacturing techniques for dumbbells, dumbbell plates, barbells, barbell plates, kettlebells or weight bars for existing sports products on the market: 1. Cast iron; 2. First make dumbbells, dumbbell plates, A plastic shell in the shape of a barbell, plate, kettlebell, or weight bar, filled with cement mixture to the desired weight. [0003] The above-mentioned cast iron dumbbells, dumbbell plates, barbells, barbell plates, kettlebells or weight bars have high production costs. During the casting process, the size and weight of the products are not easy to control, the quality is not stable enough, the scrap rate is high, and the environment is polluted. High energy consumption. Dumbbells, dumbbell plates, barbells, barbell plates, kettlebells or weig...
