DETAILED DESCRIPTION

[0053] The application provides a kind of anti-wind ceramic insulator and preparation method thereof as shown in Figures 1-9 The application provides a kind of anti-wind ceramic insulator and preparation method thereof as shown in

[0054] Reference Figures 1 to 4 The anti-wind ceramic insulator includes a first umbrella skirt 101, a second umbrella skirt 102 and a ceramic insulator sleeve 103, the ceramic insulator sleeve 103 is a cylindrical structure, the inner circle of the ceramic insulator sleeve 103 has an internal thread structure, the first umbrella skirt 101 and the second umbrella skirt 102 are fixedly arranged at the outer circle of the ceramic insulator sleeve 103, the outer circle diameter of the first umbrella skirt 101 is larger than that of the second umbrella skirt 102, the first umbrella skirt 101 and the second umbrella skirt 102 are provided with a plurality of, and the plurality of first umbrella skirts 101 and the second umbrella skirts 102 are sequentially arranged from top to bottom along the height direction of the ceramic insulator sleeve 103.

[0055] In order to improve the wind resistance of the porcelain insulator, the first circular hole 402 and the second circular hole 401 are arranged on the first umbrella skirt 101 and the second umbrella skirt 102 respectively, the second circular hole 401 vertically penetrates the upper and lower surfaces of the second umbrella skirt 102, and the first circular hole 402 obliquely penetrates the upper and lower surfaces of the first umbrella skirt 101, the position of the first circular hole 402 penetrating the upper surface of the first umbrella skirt 101 is close to the inner circle of the first umbrella skirt 101, the position of the first circular hole 402 penetrating the lower surface of the first umbrella skirt 101 is close to the outer circle of the first umbrella skirt 101, and the distance between the position of the first circular hole 402 penetrating the lower surface of the first umbrella skirt 101 and the axis of the porcelain insulator sleeve 103 is greater than the outer diameter of the second umbrella skirt 102.

[0056] Reference Figure 6 When the porcelain insulator is subjected to wind force, the wind force can penetrate the second circular hole 401 and the first circular hole 402, achieving the purpose of dispersing wind force, and avoiding the risk of stress concentration and damage due to the excessive concentration of wind force on the porcelain insulator.

[0057] For example, when wind force blows upward from the bottom of the second umbrella skirt 102, the connection of the porcelain insulator is prone to loosen under long-term action, and the second circular hole 401 in the present application can guide the wind force acting on the bottom of the second umbrella skirt 102 to the bottom of the first umbrella skirt 101, and then blow upward through the first circular hole 402 on the first umbrella skirt 101, achieving the purpose of dispersing wind force and guiding wind force to discharge.

[0065] Third step: hole forming, put the mixed raw materials into the mold, and form them by pressure forming, while forming circular holes penetrating the upper and lower surfaces at the predetermined positions of the umbrella skirt. In the forming process, the pressure and time should be controlled to ensure that the shape and size of the circular hole meet the requirements, and the hole wall is smooth and flat;

[0066] Fourth step: drying treatment, put the formed insulator together with the mold into a drying device for slow drying to remove the water in it, preventing problems such as pores or cracks caused by excessive water during firing. During the drying process, the temperature and humidity should be controlled to avoid adverse effects on the insulator;

[0067] Fifth step, firing process, after drying the insulator into the firing furnace, according to the pre-set firing curve, the firing temperature is generally around 1200-1300 DEG C, the specific temperature and time are adjusted according to the raw material and product requirements, in the firing process, the raw material in the round hole also occurs physical and chemical changes with the temperature rise, gradually solidified into shape, form smooth inner wall;

[0069] In summary, the porcelain insulator in the application can be made by the method of first making a hole and then firing, which is simple to produce, only needs to be dried before firing, and the temperature needs to be controlled during firing.

[0070] The method of first firing and then making a hole includes:

[0071] First step: forming and firing, similar to the conventional insulator manufacturing process, first mix the porcelain raw materials into a shape and then fire, to obtain a complete insulator shed, in the firing process, the firing process parameters need to be strictly controlled to ensure that the quality and performance of the insulator meet the requirements;

[0072] Second step: positioning and marking, on the fired insulator shed, the position of the round hole is determined according to the design requirements, and the mark is made, so that the hole can be accurately made in the subsequent processing;

[0073] Third step: selection of hole making equipment, high-precision hole making equipment such as numerical control drilling machine or laser drilling machine is selected, these equipment can accurately control the position, size and depth of the hole making, and also can ensure the smoothness of the inner wall, for porcelain material, laser drilling machine may be more suitable, because it can use high energy of laser to quickly melt the material, forming a smooth hole wall;

[0074] Fourth step: hole making process, the insulator shed is fixed on the workbench of the hole making equipment, and the hole is made according to the pre-marked position, in the hole making process, the feed speed and cutting parameters need to be controlled to avoid damage or cracks to the insulator, if laser drilling is used, the power, pulse width and frequency of the laser need to be adjusted according to the characteristics of the material and the size requirements of the hole, to obtain the ideal quality of the inner wall of the hole;

[0075] Fifth step: hole wall treatment, after the hole making is completed, the inner wall of the hole is checked, if there are burrs or rough places, special tools can be used for cleaning and polishing, for the hole formed by laser drilling, since its inner wall is relatively smooth, it only needs to be simply cleaned.

[0076] Step 6: Quality inspection. The processed insulators undergo rigorous quality inspection, including indicators such as the dimensional accuracy, positional accuracy, and inner wall smoothness of the round holes, to ensure that they meet the design requirements and usage standards.

[0077] In summary, the porcelain insulator of this invention is manufactured by firing first and then drilling, which can avoid the phenomenon of excessive deformation of the hole during the firing process, which would require repair. The appropriate manufacturing method can be selected according to actual needs, which will not be elaborated here.
