Embodiment 1

[0011] figure 1 , Figure 4 It is an embodiment of the present invention. Its specific production method:

[0012] Step 1: Select the required aluminum mesh and cut it into a rectangle according to the size, and reserve the side for folding and fastening.

[0013] Step 2: Fold the folded edge to the same direction to form an acute angle;

[0014] Step 3: Roll the folded aluminum mesh into a cylinder and fasten the folded sides together (such as Figure 4 shown);

[0015] Step 4: Put the cylindrical mold into the cylinder, press the folded edge with a smooth weight,

[0016] Take out the mould, and make the shielding net cover cylindrical body 1;

[0017] Step 5: Select the required aluminum mesh and cut out the circular top cover 2 according to the size;

[0018] Step 6: Sew the finished shielding grill cylinder body 1 and shielding grill top cover 2 with metal wire 3 to form a finished product.

Embodiment 2

[0020] figure 2 , Figure 5 It is another embodiment of the present invention, and its specific production method is:

[0021] Step 1: Select the required aluminum mesh and cut it into a rectangle according to the size, and reserve the welding edge.

[0022] Step 2: Roll the aluminum mesh with welded edges into a cylinder, and weld the overlapping two edges to each other to form a cylinder 1 .

[0023] Step 3: Select the required aluminum mesh and cut out the circular top cover 2 according to the size. There are welding legs 4 on the circumference of the top cover 2 .

[0024] Step 4: Weld the cylinder body 1 and the welding legs 4 on the top cover 2 to form a finished product.

Embodiment 3

[0026] image 3 It is another embodiment of the present invention, and its specific production method is:

[0027] The first step: the selected aluminum material is stretched into a cylinder with a cover 1 at one time;

[0028] Step 2: Carry out photo-etching on the cylindrical body 1 to etch out the required mesh holes to make a finished product.

[0029] The microwave sulfur lamp shielding net cover made by the above embodiment is not easy to corrode at high temperature, and the conductivity and reliability are greatly improved, thereby ensuring the normal start-up of the microwave sulfur lamp and prolonging its service life.

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 toa 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 netcover 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 [0001] The invention relates to a shielding net cover of a microwave sulfur lamp and a manufacturing method thereof, belonging to the technical field of electric light sources. Background technique [0002] Microwave sulfur lamp is a kind of high-efficiency and energy-saving light source newly invented in recent years. It has the advantages of high luminous efficiency, long life, natural light color, no mercury hazard, low ultraviolet, low infrared, small illuminant, and easy configuration of lamps, etc., and has attracted people's attention. The shielding mesh in traditional microwave sulfur lamps is made of stainless steel. Although this shielding mesh can shield microwaves and the molding process is very simple and mature, the shielding mesh is at a temperature of several hundred degrees when the microwave sulfur lamp is working. In a high-temperature environment, the stainless steel mesh cover is easily rusted, blackened, deformed or...
