Among them, due to the high price of 304# stainless steel, the electric telescopic door processed with 304# stainless steel is expensive and gradually withdraws from the market.
[0003] The 201# stainless steel electric telescopic door widely used in the market at this stage has the following limitations: (1) The material is thin. 0.4, which makes the overall wind resistance and impact resistance of the door poor; (2) 201# stainless steel is composed of 17Cr-4.5Ni-6Mn-N, which is a substitute for Ni-saving steel 301# stainless steel, and its manganese content is relatively low. High, low nickel content, so that it is inevitable to rust in acidic, high humidity, and chemical environments. Rusty electric doors not only affect the appearance of the door body, but also greatly reduce the mechanical strength; (3) Stainless steel pipe itself has a unique metallic color, the mirror surface is bright and dazzling, and the matte color is dull and single. However, stainless steel cannot be colored on the surface, which also makes some customers want to change its inherent color on the door. (4) The price of stainless steel is relatively high, even the price of 201# stainless steel is 18000-20000 yuan / ton
[0004] Another material currently used in the market, that is, aluminum alloy, has the following limitations: (1) the texture is soft, the material is light, and the mechanical strength and wind resistance are poor; (2) the aluminum alloy has a natural weathering process, Especially when it is used in the harsh environment of electric telescopic doors, which is exposed to the sun and rain, the aluminum alloy pipes will dry out and become powdered after a certain number of years, which will affect the mechanical strength and appearance of the door body; (3) the electric telescopic doors made of aluminum alloy materials Telescopic doors use plastic parts on elbows, casters, connectors and other auxiliary materials, so the overall resistance strength of aluminum alloy electric telescopic doors is low; (4) Face the same limitations as stainless steel electric telescopic doors The price is high, ranging from 60,000 to 70,000 yuan / ton, so that the competitiveness of aluminum profile electric telescopic doors in the market is average at this stage

Embodiment Construction
[0024] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0025] A method for processing and producing electric telescopic doors by using hot-dip galvanized electrostatic spray pipes, the specific steps are as follows:
[0026] (1) The outer surface of the steel pipe used must not be sticky with oil, and must not have uneven corrosion. It is not allowed to stick markers on the inner and outer walls of the steel pipe, and the steel pipe must not be artificially bent during transportation;
[0027] (2) Use 18-20% hydrochloric acid aqueous solution to pickle 2-5 tons of steel pipes for 5-15 minutes. When the pipe is lowered into the acid tank, the steel pipe is inclined at 15°. Lift one side of the steel pipe for 3 times before lifting the other side for 3 After repeating twice, lift the steel pipe. When th...

The invention discloses a method for machining and manufacturing an electric folding gate by adopting a hot dip galvanizing static plastic spraying pipe, and relates to the technical field of electric folding gate manufacturing. The method comprises the steps of a hot dip galvanizing technology of a steel pipe, spraying of a hot dip galvanizing pipe, blanking of a finished product pipe and assembling of an electric gate. According to the method, the electro-chemical protection effect can be achieved through the hot dip galvanizing technology, rusting caused by the electro-chemical corrosion is avoided, spraying can be carried out on a galvanized pipe by adopting polyester type color powder coating, a formed coating film has the advantages of being high in anti-corrosion performance, striking-resistant and scraping-resistant, and the cost of the manufactured electric folding gate has the market competitiveness.
Description
Technical field: [0001] The invention relates to the technical field of production of electric telescopic doors, in particular to a method for producing electric telescopic doors by processing hot-dip galvanized electrostatically sprayed plastic pipes. Background technique: [0002] At present, the widely used electric telescopic doors in the industry are produced and processed from pipes made of three materials: 201# stainless steel, 304# stainless steel, aluminum alloy + ABS plastic. Among them, due to the high price of 304# stainless steel, the electric telescopic door processed with 304# stainless steel is expensive and gradually withdraws from the market. [0003] The 201# stainless steel electric telescopic door widely used in the market at this stage has the following limitations: (1) The material is thin. 0.4, which makes the overall wind resistance and impact resistance of the door poor; (2) 201# stainless steel is composed of 17Cr-4.5Ni-6Mn-N, which is a substitut...
