Problems solved by technology

[0002] The shell shape of the pressure vessel has a non-single cylindrical body, such as a shell composed of a cone and a cylinder. For this non-cylindrical body, it can be formed on the spinning equipment, which has high efficiency and good quality, but for large diameter (such as more than 5000mm) of the cylinder, because the general pressure vessel enterprise has a small number of such vessels, it is extremely uneconomical to purchase such a large-scale spinning equipment, so how to design a simple tool and use commonly used equipment to form a large-diameter special-shaped cylinder It is an urgent topic for pressure vessel enterprises

Embodiment Construction

[0005] The present invention will be described in detail in conjunction with the above drawings. A vertical lathe workbench 1 is placed on a support cylinder 2 with an outer flange at the bottom, and its aperture is the same as the diameter of the middle of the conical cylinder. After being inverted in the support cylinder on the vertical lathe table 1, the support cylinder is fixed on the worktable with bolts. The circular pressure plate 4 in the conical cylinder is evenly distributed with threaded through holes along the circumference. The cylinder is pressed on the table. The main wheel 5 is placed in the upper port of the conical cylinder, and the thread on the upper end of the shaft matches the threaded hole on the lower surface of the tool holder of the vertical lathe. The spinning wheel 6 outside the upper port of the conical cylinder has its shaft. The thread on the upper end of the vertical lathe is matched with the threaded hole on the lower surface of another tool h...

Abstract

A spinning press tool for forming a cylindrical body from a conic barrel on a vertical lathe is composed of a fixing circular barrel with a diameter matched with the external diameter of the middle part of a conic barrel to be shaped, a turnover plate on the bottom of said circular barrel and with a screw hole, a pressing plate in said conic barrel and with a screw hole, a screw bolt for fixing said conic barrel to the bench of said vertical lather via said pressing plate, a cylindrical main roller arranged to upper mouth of said conic barrel, and an axle for said cylindrical main roller and connected to lower part of tool carrier.

Description

Technical field: [0001] The present invention relates to an extrusion, in particular to a spinning tool. Background technique: [0002] The shell shape of the pressure vessel has a non-single cylindrical body, such as a shell composed of a cone and a cylinder. This non-cylindrical body can be formed on a spinning equipment, which has high efficiency and good quality, but for large diameters. (For example, over 5000mm), the general pressure vessel enterprises are extremely uneconomical to purchase such large-scale spinning equipment due to the small number of such vessels. Therefore, how to design a simple tool to use commonly used equipment to form large-diameter special-shaped cylinders It is an urgently needed topic for pressure vessel enterprises. Invention content: [0003] The object of the present invention is to provide a spinning tool that can spin a conical cylinder into a cylindrical segment on a vertical lathe. The technical scheme of the present invention is ...
