Problems solved by technology
[0003] Traditionally, there are resin finished drains, PE finished drains, and brick and concrete drains. Resin drains and PE finished drains have the disadvantages of aging, acid and alkali resistance, and frost resistance, which can easily lead to cracking and blockage of drains, etc. problem, which will cause the gutter to gradually lose its drainage function
Traditional brick and concrete drainage ditches are not strong enough and have a short service life. On-site construction will bring dust, noise, and garbage to the city; , it will become smelly and pollute the surrounding environment; and if stainless steel is used to make finished drains, the above defects can be made up for by the characteristics of stainless steel
[0004] However, due to the material of stainless steel, it is difficult to make it into a finished drainage ditch.

The invention discloses a manufacturing process of a finished stainless steel drainage ditch and belongs to the field of auxiliary facilities for road engineering construction. The problem that stainless steel drainage ditches are not convenient to produce is solved. According to the technical scheme, the manufacturing process is characterized by comprising the following steps of S100, cutting, S200, annealing treatment, S300, drawing, S400, joint treatment, S500, deburring of an upper opening, S600, turnup machining, S700, cleaning and grinding, S800, shot blasting and S900, acid pickling andpassivation, specifically, in the step of cutting, a stainless steel board is cut by a laser cutting machine to form basic shape of a workpiece. The finished stainless steel drainage ditch is simplein manufacturing process, convenient to produce, resistant to acid and alkali, resistant to aging, free of pollution and long in service life, is integrally formed through the stainless steel board, and is directly installed and used without welding.
Description
technical field [0001] The invention relates to the field of road engineering construction auxiliary facilities, in particular to a manufacturing process of stainless steel finished drains. Background technique [0002] The drainage ditch refers to the ditch that guides the water collected in the side ditch, intercepting ditch, and near the roadbed, in the crop field, and in the low-lying places near the residence to the roadbed, crop field, and residential area. Drainage ditches can be divided into open ditch and hidden ditch according to the location of their construction. In the vast fields, open ditches are generally used; in cities, road tunnels, aqueducts, and on both sides of some roads, dark ditches are used. [0003] Traditionally, there are resin finished drains, PE finished drains, and brick and concrete drains. Resin drains and PE finished drains have the disadvantages of aging, acid and alkali resistance, and frost resistance, which can easily lead to cracking ...
