Abstract
A microwave sulphur lamp shielding net cover with the shape of a tube made of aluminium has holes on the cover and side wall. The producing method is to select the needed alluminum with net to cut to a rectangle to roll up and to couple and press both ends with heming press or welding to a tube to sew up one end of tube and the matched top cover with wire or welding forming an aluminum screen net cover or to form a tube with cover with aluminum by pulling, spreading and squeezing which will be corroded by photo taken to the desired net holes. Said screen net cover is not easy to be corroded under the mirowave sulphur lamp with good conductivity and reliability to sexure the normal starting and longer its lifetime.
Description
Technical field
The present invention relates to shielding new cover of a kind of microwave sulfur lamp and preparation method thereof, is to belong to the electric light source technology field.
Background technology
Microwave sulfur lamp is neoteric in recent years a kind of energy-efficient light source.It integrate high light efficiency, long-life, photochromic natural, no mercury evil, low ultraviolet, low infrared, luminous element is little, be convenient to dispose advantage such as light fixture, extremely people pay close attention to.What the gauze screen in traditional microwave sulfur lamp all adopted is that stainless steel material is made, though this shielding new cover can shield microwaves and moulding process also very simple, ripe, but gauze screen is in the hot environment of several Baidu when microwave sulfur lamp is worked, the stainless steel guard is easy to be turned black, be out of shape even split by corrosion, not only influence the shielding of microwave, main be that stainless steel guard material changes after, the obvious variation of its electric conductivity, make the startup of microwave sulfur lamp become undesired, reduced the life-span of microwave sulfur lamp.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art and defective, for microwave sulfur lamp provides new shielding new cover, with startup problem that solves microwave sulfur lamp and the dependability that improves it.The shielding new cover of this microwave sulfur lamp is cylindrical, has mesh on its top cover and the perisporium, and it is that aluminum material is made; This shielding new cover can be cut into rectangle with the aluminium net, and is rolled into cylindricly, and the edge, both sides is connected, and an end of cylindrical shell is connected with the aluminium net top cover that is complementary with it; The two edges of its cylindrical shell can fasten pressurization with flanging and make it to be connected to each other, and also can make it to connect with welding, and its top cover and cylindrical shell one end can sew up with wire, also can make it to connect with welding method; This shielding new cover also can form the cylinder of band top cover with the aluminium drawing and forming, and the perisporium with it corrodes into required mesh with top cover then.Microwave sulfur lamp shielding new cover of the present invention is owing to use aluminum material to make, therefore its cost reduces greatly, also overcome simultaneously the defective that traditional stainless (steel) wire covers on its electric conductivity of easy oxidation affects under the high temperature, fundamentally solve the startup problem of microwave sulfur lamp, and increased the useful life of microwave.

Embodiment
Fig. 1, Fig. 4 are a kind of embodiment of the present invention.Its concrete manufacture method:
The first step: choose required aluminium net and be cut into rectangle, and reserve the limit that flanging fastens by size.
Second step: the limit that flanging is fastened is converted into acute angle to same direction;
The 3rd step: the aluminium net volume that will roll the limit well becomes tubular and the limit of rolling well is fastened (as shown in Figure 4) mutually;
The 4th step: cylindrical die is put in the tube, pressurizeed in the limit that flanging fastens with ganoid weight,
Take out mould, make shielding new cover cylindrical shell 1;
The 5th step: choose required aluminium net and cut out circular top cover 2 by size;
The 6th step:, make finished product with ready-made shielding new cover cylindrical shell 1 and shielding new cover top cover 2 usefulness wires 3 sews.
Fig. 2, Fig. 5 are another kind of embodiment of the present invention, and its concrete manufacture method is:
The first step: choose required aluminium net and be cut into rectangle, and reserved toe by size.
Second step: will stay the aluminium net volume of toe to become tubular, and overlapping two edges be welded into cylindrical shell 1 mutually with welding manner.
The 3rd step: choose required aluminium net and cut out circular top cover 2, welding leg 4 is arranged on the circumference of top cover 2 by size.
The 4th step: finished product is made in cylindrical shell 1 and the welding leg 4 mutual welding on the top cover 2.
Fig. 3 is another kind of embodiment of the present invention, and its concrete manufacture method is:
The first step: the aluminium that will choose is with the disposable cylinder with cover 1 of making of drawing and forming;
Second step: cylinder 1 is carried out photoetching, erode away the mesh that needs, make finished product.
At high temperature not perishable with the microwave sulfur lamp shielding new cover that the foregoing description is made, conductivity and reliability improve greatly, thereby have guaranteed the normal startup of microwave sulfur lamp and prolonged its useful life.
Claims (4)
1, a kind of microwave sulfur lamp shielding new cover, it is cylindrical, has mesh on its top cover and the circle wall, it is characterized in that this guard is to be made by aluminum material.
2, the manufacture method of microwave sulfur lamp shielding new cover according to claim 1 is characterized in that its adopts aluminium net to be cut into rectangle, it is rolled into cylindric, and two edges is connected to each other, and an end of cylindrical shell is connected with the aluminium net top cover that is complementary with it.
3, its shaping process of microwave sulfur lamp shielding new cover according to claim 2, it is characterized in that its two edges of described tubular aluminium net can fasten pressurization with flanging and make it to be connected to each other, also can make it to connect with welding, its top cover and tubular aluminium net one end can sew up with wire, also can make it to connect with welding.
4, its shaping process of microwave sulfur lamp shielding new cover according to claim 1 is characterized in that its employing aluminium stretching extrusion modling forms the cylinder of band top cover, and perisporium and the top cover at it corrodes into needed mesh then.
