Super-large intelligent vertical hydraulic cold pipe bender

Abstract

The invention provides a super-large intelligent vertical hydraulic cold pipe bender comprising a bender body main frame as well as an upper mould, a lower mould, a clamping mould and a driving mechanism which are arranged on the bender body main frame. The super-large intelligent vertical hydraulic cold pipe bender is technically characterized in that the clamping mould, the upper mould and the lower mould are sequentially arranged along the length direction of a steel pipe, and a wedge block cylinder mechanism is arranged under a base of the clamping mould; the side wall of the outer side of the bender body main frame is provided with an intelligent console on which a liquid crystal touch display screen, an alarm, pressure gauges, a bending resultant force display instrument, a wedge block supporting force display instrument, an electronic receiver and a control mode switch are arranged; and each of two ends of the steel pipe is provided with an electronic emitter provided with a magnetic base, and inlets of bending cylinders are provided with pressure sensors. The super-large intelligent vertical hydraulic cold pipe bender is simple in processing technology and low in processing cost; and the difficulty of processing double curved surfaces on the upper mould is solved, and meanwhile, all steps for bending the pipe by using the pipe bender are finished once, so that the pipe bending process is programmed and intelligentized, the labor amount of a worker is reduced, and the pipe bending efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a super-large intelligent vertical hydraulic cold bending machine. Background technique [0002] Since the reform and opening up, my country's national economy has developed rapidly. In 2015, my country's total economic volume has reached 67.67 trillion (RMB), ranking second in the world. However, with the development of the economy, the environmental pollution is also becoming more and more serious, especially the air quality index PM2.5 seriously exceeds the standard, and severe smog weather has appeared in Beijing, North China, East China and other regions. According to data released by the School of Environmental Sciences of Peking University, only 20% of the cities in my country meet the air quality standards. If environmental pollution is not resolved, it will seriously affect China's image, and it will even affect the pace of reform and opening up. The par...

Problems solved by technology

The surface of the upper tire is generally formed by casting or CNC machine tools, but the casting process is difficult, and the surface of the casting is very inaccurate, and it needs to be ground with a grinding wheel according to the sample. Often after more than ten days of grinding, it cannot meet the requirements at the end, which is time-consuming and laborious; while CNC machine tool processing There are also the problems of high processing cost and long time
