Abstract

The invention belongs to the technical field of semicircular plate manufacturing devices, and particularly relates to a semicircular plate pressing die and a semicircular plate manufacturing method. The semicircular plate pressing die comprises a pressure head installed on an upper cross beam of a press machine, and a plurality of concave dies installed on a movable anvil table of the press machine; the upper end faces of the concave dies are provided with circular cavities, and each circular cavity extends to the other side face, arranged oppositely, of each concave die from one side face ofthe concave die; the concave dies are connected with each other in sequence, and the circular cavities communicate with each other in sequence; and the pressure head is arranged above the concave dies, and can be driven by the press machine to extend into the circular cavities. When a large number of the concave dies are provided, a semicircular plate with the length of larger than 4000 mm can bemanufactured by pressing; and when a small number of the concave dies are provided, a shorter semicircular plate can be manufactured by pressing. The semicircular plate pressing die is simple in structure, wide in application range and high in practicability, and applicable for pressing of semicircular plates in different lengths.

Description

technical field [0001] The invention belongs to the technical field of semicircular plate manufacturing devices, in particular to a semicircular plate pressing mold and a semicircular plate manufacturing method. Background technique [0002] There are generally two ways to produce the semi-circular plates used in the pile legs of the drilling platform, which are seamless steel pipe cutting and processing or the production process of heating and pressing steel plates at high temperature. Among them, the semicircular plate cut and processed by seamless steel pipe will have problems such as uneven wall thickness, large deviation of material mechanical properties, low material utilization rate, and low cutting and processing efficiency. In order to avoid the above-mentioned problems, most of the current semi-circular plate manufacturing methods use steel plate heating and high-temperature pressing process. However, after the steel plate is processed by this process, subsequent q...
