Problems solved by technology

Due to the need for turnover after heating, the heated workpiece is exposed to the outside, which will not only cause heat loss of the workpiece, but also cause workers to be scalded.
In addition, since the workpiece itself is fully heated, during the bending process, the area that does not need to be bent may also be deformed, resulting in a relatively high defect rate of the workpiece.

Abstract

The invention discloses a large-size angle steel high-frequency heating single-face bending machine used for an extra-high voltage iron tower. The large-size angle steel high-frequency heating single-face bending machine comprises a base. Workpiece placing racks are symmetrically fixed to the front end and the back end of the top surface of the base. A pressing block is connected to the position above the workpiece placing racks in an up-down movement mode. A bending pressing die is fixed to the bottom surface of the pressing block and located between the workpiece placing racks. The pressing block provides the driving force through a hydraulic piston which is fixed to a top plate. The top plate is fixed to the base through vertical posts. High-frequency heating machines are arranged on the left side and the right side of the base correspondingly. The shape defined by heating coils of the high-frequency heating machines is the same as that of a bent and deformed region of a workpiece. By means of the structure of the large-size angle steel high-frequency heating single-face bending machine, the high-frequency heating machines and the bending mechanism are combined together, and after being heated, the workpiece can be bent immediately without turnover, so that the heat loss is avoided, and energy consumption is reduced; and meanwhile workpiece turnover is omitted, the production efficiency is improved, and the hidden danger that an operator is scalded by the workpiece in the workpiece turnover process is also avoided.

Description

technical field [0001] The invention relates to the field of manufacturing large-size angle steels for UHV iron towers, in particular to a high-frequency heating single-side bending machine for large-size angle steels for UHV iron towers. Background technique [0002] UHV can greatly enhance the transmission capacity of my country's power grid. According to the data provided by the State Grid Corporation of China, the UHV DC power grid of the primary circuit can transmit 6 million kilowatts of electricity, which is equivalent to 5 to 6 times that of the existing 500 kV DC power grid, and the power transmission distance is also 2 to 3 times that of the latter. Therefore, the efficiency is greatly improved. In addition, according to the calculations of the State Grid Corporation of China, if the power transmission of the same power is carried out, the use of UHV lines can save 60% of land resources compared with the use of 500 kV high-voltage lines. [0003] Compared with or...
