Definitions

  • the present invention relates to a method of making a dumbbell sheet, and more particularly to a method of making a solid metal dumbbell sheet.
  • Dumbbells are common fitness equipment. The main working principle is to use their quality to increase the arm load and achieve the exercise effect. At present, most of the known solid metal dumbbell sheets are cast from cast iron materials, and the casting and cooling time is long. Therefore, the method has low production efficiency, high production cost, and high energy consumption.
  • the object of the present invention is to overcome the deficiencies of the prior art and to provide a method for manufacturing a dumbbell sheet which has lower cost, lower energy consumption and higher production efficiency.
  • the technical solution adopted by the utility model is: a method for manufacturing a fixed weight dumbbell piece, which comprises the following steps:
  • the first step the scrap iron scraps are first divided by the machine to make it substantially uniform;
  • the second step making the iron cake, putting the iron filings into the disc cake mold according to the specified weight, and continuously applying pressure;
  • the third step heating the iron cake with high frequency
  • Step 4 Put the discus into the molding die and apply pressure continuously.
  • the amount of iron filings is 0.5-15 kg, the pressure is applied 100 ⁇ 10 4 -300 ⁇ 10 - 4 N, and the pressure is continued for 5-20 s.
  • the iron cake is heated to 1000-1200 degrees Celsius.
  • a pressure of 100 ⁇ 10 4 - 300 ⁇ 10 4 N is applied, and the pressure is continued for 5-20 s.
  • the invention utilizes waste iron scrap as a raw material, and the recovery price is only about one-fifth of the price of steel, the raw material price is low, and the production cost is lower; the energy consumed by the high-frequency heating, plus the energy consumed by the machine tool, and the casting phase Compared with the energy consumption, the energy consumption is greatly reduced; the flow operation does not require waiting, and the production efficiency is higher; the product is firm enough to meet the requirements for use.
  • Figure 1 is a schematic view showing the structure of a dumbbell piece produced by the present invention.
  • FIG. 2 is a schematic view showing the compression of a discus into a dumbbell piece according to the present invention.
  • a method of making a fixed weight dumbbell piece comprising the steps of:
  • the first step the scrap iron scraps are first divided by the machine to make it substantially uniform;
  • the second step making the iron cake, placing the iron filings into the disc cake mold according to the specified weight 0.5kg, continuously applying pressure 150 ⁇ 10 4 N for 10s;
  • Step 3 Use high frequency to heat the discus to 1200 degrees Celsius
  • the fourth step as shown in Fig. 2, the iron cake is placed in a molding die, and the pressure is continuously applied for 150 ⁇ 10 4 N for 15 s. Finally, the surface of the dumbbell will be made of a plastic layer or a paint layer. After completion, the appearance is good and meets the requirements (as shown in Figure 1).
  • the iron cake is heated to 1000 degrees Celsius
  • the pressure is continuously applied at 100 ⁇ 10 4 N for 20 s.
  • the iron cake is heated to 1100 degrees Celsius
  • the pressure is continuously applied at 300 ⁇ 10 4 N for 5 s.

Abstract

La présente invention concerne un procédé de fabrication d'une plaque de poids ayant un poids fixe pour un haltère qui comprend : la conduite, au moyen d'une machine, d'une coupe sur des déchets de ferraille pour obtenir des déchets de ferraille sensiblement uniformes ; la formation d'une plaque de fer par placement d'un poids spécifié de déchets de ferraille dans un moule de plaque de fer et compression de celui-ci ; la conduite d'un chauffage à haute fréquence sur la plaque de fer ; et le placement de la plaque de fer dans un moule de formation, et la compression de celle-ci. Le procédé utilise des déchets de ferraille en tant que matière première, de façon à diminuer les coûts de production, réduire considérablement la consommation d'énergie, améliorer l'efficacité de production et assurer une rigidité suffisante d'un produit. Le procédé est également applicable à la fabrication d'une plaque de poids métallique solide pour un haltère.
