The dumbbell and barbell products has the advantages that the raw materials of the products are inexpensive metallic wastes of machining; the products are convenient in process and low in energy consumption compared with the traditional products; the products have the advantages of high strength of the composite material, high density and the like, and the bottleneck of prior arts is overcome; the process does not produce environmental pollution and occupational health injuries during the manufacturing process.
Description
Technical field
The present invention relates to a kind of body-building, sports products and method of manufacture thereof, especially a kind of dumbbell of high-quality cheaply, barbell series products and method of manufacture thereof.
Background technology
Along with the raising of living standards of the people, body-building has become trend and trend with motion, and dumbbell and barbell are the common family expenses and the exercise apparatus of gym workout center.The ME of existing dumbbell, dumbbell plate, barbell, disc, kettle-bell, weight stack, weighted rod mainly contains two kinds on the market: (1) is raw material with cast iron, casting under the high temperature about 1400 ℃; (2) make the plastic casing of dumbbell, dumbbell plate, barbell, disc, kettle-bell, weight stack, weighted rod earlier, recharge the weight that cement admixture reaches to be needed.
The production cost of the dumbbell of above cast iron quality, dumbbell plate, barbell, disc, kettle-bell, weight stack, weighted rod is high, because of casting temp up to 1400 ℃, the process energy consumption is very big; Contaminate environment; And the size and the weight of product are wayward, and quality is unstable, and scrap rate is high.The dumbbell of filling concrete mixture, dumbbell plate, barbell, disc, kettle-bell, weight stack, weighted rod, production cost is relatively low, but because the cement admixture density of filling is too low, the small product size of same weight specification is a lot of greatly, is inconvenient to use.And the product of filling concrete mixture is not anti-to be fallen, and the quality product wearing quality is relatively poor.
Based on the shortcoming that above-mentioned traditional product exists, industry begins to explore new low cost, high quality dumbbell and barbell manufacturing process and product.Such as application number is the ME that 201110088985.4 Chinese invention patent " a kind of ME of dumbbell series products " discloses a kind of thick stick dumbbell series products; Be made into the shape that material is pressed into thick stick dumbbell series products with iron powder and tackiness agent mixing, just formed certain products after the typing demoulding is air-dry.Application number is that 201110231215.0 Chinese invention patent " body-building is with the prescription and the preparation technology thereof of moulding dumbbell ball, disc " discloses the prescription of a kind of body-building with moulding dumbbell ball, disc, it is characterized in that being made up of 75%～90% iron powder, 10%～25% epoxy resin glue.Above-mentioned two patents are raw material with cheap iron powder all, adopt cementing agent with the directly sticking glutinous aftershaping of iron powder.Because cementing agent mostly is heat cured material, therefore cause the bonding force between iron powder and the cementing agent relatively poor, adopt the anti-poor performance of falling of dumbbell of this method manufacturing, duration of service of a specified duration easy of crack.In addition, cementing agent mostly adopts volatile solvent, and occupational health safety is caused disadvantageous effect.
Summary of the invention
The objective of the invention is to overcome the deficiency that above-mentioned prior art exists, providing a kind of is that raw material is made dumbbell class and barbell series products and ME thereof with the matrix material.
The object of the invention is realized through following technical scheme: a kind of matrix material dumbbell class and barbell series products; The main material of dumbbell class and barbell series products is the matrix material that powdery or granular metallic substance and thermoplastic polyester are formed; Powdery or granular metallic substance are one or several in iron, copper, aluminium, chromium, manganese, the lead; Thermoplastic polyester is one or several in Vestolen PP 7052, PS, polymethylmethacrylate, high density polyethylene(HDPE), SE, nylon, polycarbonate, Vilaterm, urethane, tetrafluoroethylene, polyethylene terephthalate, acrylonitrile-butadiene-styrene (ABS), FM, the polyoxymethylene; Also comprise toughener in the composition material of dumbbell class and barbell series products; Toughener is one or several in spun glass, carbonate, silicate, cellulosic fibre, nylon fiber, thomel, whisker, talcum, mica, glass microballon, milled fiber, glass flake, wood powder, zeyssatite, asbestos, the carbon black; The per-cent that metallic substance accounts for the product gross weight is 10～90%; The per-cent that thermoplastic polyester accounts for the product gross weight is 10～90%, and the per-cent that toughener accounts for the product gross weight is 0～50%.
