Abstract
The invention discloses a cast aluminum alloy non-magnetic pressing ring (shown in the attached drawings in the abstract), which is characterized by comprising upper and lower rings, wherein a plurality of rib plates are supported in the middle of the upper and lower rings. The pressing ring is made of cast aluminum alloy, is non-magnetic and can have the effect of magnetic isolation. Compared with the conventional non-magnetic cast steel pressing ring, the invention has the advantages that: the weight of the pressing ring is only 35 percent of the original weight; a casting process is simple, and the yield of a finished product is improved by 20 to 30 percent; the pressing ring is relatively easy to machine, and consumption of cutters and cutting tools is only 1/5 to 1/10 of the original consumption; the production period is shortened by 1/4 to 1/3 compared with the original production period; and the manufacturing cost is reduced by 20 to 25 percent compared with the original manufacturing cost.
Description
Technical field
The present invention relates to that a kind of self is light, low cost of manufacture, can play the high-voltage power machine part of no magnetic separated magnetic effect again, is that a kind of Birmasil does not have the magnetic pressure circle specifically.
Background technology
No magnetic pressure circle is a kind of important heavy parts in the high-voltage generator, extensively adopts on various high-voltage generators.Because no magnetic pressure circle serviceability particularity requires self no magnetic or weak magnetic, is used for reducing generator magnetic eddy current power consumption, improve generator efficiency, reduce the generator temperature rise.It all is to adopt no magnetic cast steel that present high-voltage generator does not have the magnetic pressure loop material.
No magnetic cast steel trim ring mainly contains following shortcoming:
1.. own wt is big, has increased the total weight of generator;
2.. complex process during castings production, the finished product qualification rate is low;
3.. mechanical processing difficulty is big, and cutter and cutlery loss are big;
4.. the manufacturing cycle is long, the cost of goods manufactured height.
Summary of the invention
In order to solve the deficiency of no magnetic cast steel trim ring, the invention provides a kind of Birmasil does not have the magnetic pressure circle, and it has alleviated the own wt of part, has improved the finished product qualification rate, has reduced mechanical processing difficulty and cost of goods manufactured.
In order to achieve the above object, technical scheme of the present invention is that a kind of Birmasil does not have the magnetic pressure circle, and it has following characteristics:
1.. its profile is upper and lower two several gussets of circle intermediate supports;
2.. what material adopted is Birmasil;
3.. self be no magnetic, and can play separated magnetic effect.
The existing no magnetic cast steel trim ring of the present invention has following significant effect:
1.. weight has only 35% of original weight;
2.. casting technique is simple, and the finished product qualification rate improves 20～30%;
3.. the machining ratio is easier to, and cutter, cutlery loss have only original 1/5～1/10;
4.. the production cycle shortens 1/4～1/3 than original;
5.. manufacturing cost reduces by 20～25% than original.
Description of drawings
Fig. 1 is the sketch that a kind of Birmasil does not have the magnetic pressure circle.
Specific embodiments
The invention will be further described below in conjunction with accompanying drawing 1, is that Φ 2390 highly is that 224 Birmasils do not have the magnetic pressure circle as making maximum outside diameter, can realize technical scheme of the present invention as follows:
1.. make model with desiccated wood or foamed plastic;
2.. use phenolic sand molding, and make cup, cross gate and rising head by technology;
3.. prepare aluminium alloy ingots ZL111 (but preparing burden in the stove) with the melting of special-purpose casting aluminium stove;
4.. aluminum alloy melting is through removing slag and sample analysis, and pour into a mould at 700～760 ℃ the qualified back of composition;
5.. after casting solidification finished, dead head and the sand grains that sticks to foundry goods were removed in the sand removal of unpacking;
6.. foundry goods is carried out solution heat treatment;
7.. according to drawing foundry goods is carried out machining, make it reach figure paper size and tolerance and Geometrical Tolerance Principle.
Claims (1)
1. a Birmasil does not have the magnetic pressure circle, it is characterized in that: it comprises following characteristics:
1.. its profile is upper and lower two circles, several gussets of intermediate supports;
