Abstract
The utility model relates to an iron core of a magnesium bar of an antiskid water heater, which belongs to the technical field of a sacrificial anode of magnesium alloy. The iron core of the magnesium bar of the antiskid water heater comprises a magnesium bar, wherein the iron core is coated in the center of the magnesium bar. The iron core of the magnesium bar of the antiskid water heater is characterized in that a coating part of the iron core is provided with a groove. Compared with the prior art, the utility model and the magnesium alloy are firmly combined and are not easy to loosen. By a boosting experiment, the iron core is not loosened under 40N, and the qualified rate of the magnesium bar is greatly enhanced.
Description
Technical field
The utility model belongs to the sacrificial magnesium alloy anode technical field, is specifically related to a kind of anti-skidding water-heater magnesium rod iron core.
Background technology
The sacrificial magnesium alloy anode rod that protection against corrosion is used (be called for short magnesium rod) as galvanic protection to the protection bather safety play crucial effects.
In the prior art, the making processes of magnesium rod is: 1) iron core car silk; 2) magnesium melting cast molding; 3) revise polishing; 4) check; 5) packing is dispatched from the factory.Wherein, generally need to detect iron core and magnesium alloy interfused firmness in the check, iron core and magnesium when 20N, occur becoming flexible be judged to defective.
Summary of the invention
The purpose of this utility model provides a kind of anti-skidding iron core, overcomes problems of the prior art, improves the qualification rate of magnesium rod.、
The following technical scheme of the concrete employing of the utility model:
A kind of anti-skidding water-heater magnesium rod iron core comprises the magnesium rod, and iron core is coated on the center of magnesium rod, it is characterized in that, is provided with groove in the coating portion of iron core.
Optimized technical scheme is: in the iron core front axle to being arranged with 2 grooves.
According to the prompting of prior art, also has screw thread at the rear portion of described iron core.
Method for making of the present utility model and prior art are basic identical, just stamp out groove in the iron core front portion before the magnesium melt casting.
Compared with prior art, the utility model combines firmly with magnesium alloy, is not easy to become flexible.Through afterburning test, iron core is not loosening under 40N, has improved the qualification rate of magnesium rod greatly.
