Abstract

The invention discloses a magnetic conduction weight ring, a magnetic control wheel and a preparation method thereof. Among them, the raw materials of the magnetically conductive counterweight ring include: 30-80 mesh iron powder, 3-8% manganese sulfide by weight of iron powder, sodium silicate by 3-8% weight of iron powder and 6-12% by weight of iron powder graphite powder. The preparation method includes the following steps: 1), stirring the raw materials evenly; 2), pressing the iron powder ring by a hydraulic press, and adjusting the cross-sectional area of ​​the iron ring within the range of 3000-6000 MPa; 3), putting the iron powder ring into an electric furnace, The electric furnace first uses 400-800 degrees for 5-15 minutes; then uses 1000-1200 degrees for 5-15 minutes; 4) 300-600 tons of hydraulic press for secondary pressing. The invention has the effects of waste utilization, energy consumption reduction and cost reduction.

Description

technical field [0001] The invention relates to the field of fitness equipment, in particular to a magnetically conductive weight ring, a magnetic control wheel and a preparation method thereof. Background technique [0002] The magnetic control wheel of the magnetic control exercise bike is the driven wheel on the exercise bike, which has the function of keeping the pedaling inertial and significant resistance training. It mainly provides resistance to exercise bikes through magnetic force and electromagnetic induction. According to the different installation positions of the magnet, the magnetron wheel can be divided into outer magnetron wheel, inner magnetron wheel, side magnetron wheel and so on. [0003] Such as figure 1 As shown, the main body of the existing magnetron wheel is mainly made of cast iron. The main body of this kind of wheel needs to be made into a sand box first, and then the melted metal is cast in the sand box, and then the sand is produced and repai...
