Embodiment
[0015] A kind of manufacturing method of the railway tank car tank shell cylinder of the present invention, concrete method is:
[0016] Such as image 3 As shown, first, the uncoiled and leveled sheet is rolled into the required diameter of the cylinder with the width of the sheet as the pitch, and welded while rolling to achieve continuous production. When the length of the cylinder reaches the requirements of the drawing, the cylinder is cut off. When one roll of steel plate is about to be used up, the head of another roll of steel plate is welded to the tail of the steel plate and then the coiling is continued, and the production of the cylinder is completed in this cycle.

The invention relates to a method for manufacturing a tank cylinder of a tank car, and belongs to the field of manufacturing of tank cars. The method for manufacturing the tank cylinder of the tank car particularly comprises the steps that firstly, a board is spirally wound into a cylindrical shape with the board width as the thread pitch, and the diameter of the cylinder is matched with the diameter of the tank cylinder of the tank car; and two connecting positions of the board wound into the cylindrical shape are welded through welding equipment, and when the length of the cylinder reaches the designed length, the length is cut off to form the cylinder meeting the requirement. According to the method, the machining difficulty of the tank cylinder of the tank car is reduced, the manufacturing quality of the cylinder is improved, continuous production is achieved, and the production efficiency is improved.
Description
technical field [0001] The invention relates to a method for manufacturing a tank body of a railway tank car, belonging to the field of railway tank car manufacturing. Background technique [0002] In the manufacture of railway tank cars, the manufacturing methods of the cylinder mainly include the manufacturing process of the upper and lower plates of the cylinder and the manufacturing process of the cylinder joint. The manufacturing process of the upper and lower plates of the cylinder is to divide the cylinder into two or four plates, and then splice the two or four plates and roll them into two semi-circular arc plates, such as figure 2 As shown, then, determine the circumference of the cylinder according to the circumference of the head, and finally cut off the upper and lower circular arc plates to form butt welding. This method has the following disadvantages: 1. There is a diameter error in the rolling of the upper and lower circular arc plates, and the adjustment w...
