Blank feeding mechanism for ultra-large intelligent vertical hydraulic pipe cold-bending machine

Abstract

The invention relates to a tire loading mechanism for an ultra-large intelligent vertical hydraulic cold bending machine, which includes an arc-shaped bottom plate. The reinforced plate and a plurality of reinforced arc plates intersected with the reinforced plate, the inner arc surface of the arc-shaped bottom plate is welded with a plurality of supporting arc plates at intervals, and the upper surface of the supported arc-shaped plate is continuously welded with a plurality of arc-shaped bottom plates An axially extending reinforcing bar, the upper surface of the reinforcing bar is continuously welded with a protective plate covered with a polyurethane protective layer to form the inner surface of the tire loading mechanism, and the inner surface of the tire loading mechanism is formed along the arc-shaped bottom plate A hyperboloid with a high axis in the middle and low ends. The processing technology is simple and the processing cost is low, which solves the difficulty of processing the hyperboloid surface of the upper tire, and at the same time ensures the accuracy of the bending arc of the steel pipe in the hyperboloid surface.

Description

technical field [0001] The invention relates to a composition mechanism of a pipe bending machine, in particular to a super large intelligent vertical hydraulic cold pipe bending machine with tire loading mechanism. 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 will even affect the pace ...

AI Technical Summary

Problems solved by technology

[0003] The tire loading mechanism of the pipe bending machine determines the bending curvature of the pipe, and is an important part of the pipe bending machine. The existing surface of the tire loading mechanism and the pipe contact is generally formed by casting or CNC machine tools, but casting molding is difficult. , the surface of the casting is very inaccurate, and it needs to be ground with a grinding wheel according to the model. Often after more than ten days of grinding, it still cannot meet the requirements, which is time-consuming and laborious; and CNC machine tool processing has the problems of high processing cost and long time.
