Full-automatic pipe expanding machine and pipe expanding method

Abstract

The invention discloses a full-automatic pipe expanding machine and pipe expanding method. The machine comprises an automatic feeding and discharging device, a lifting clamping mechanism, an expandingmechanism and an axial alignment mechanism, and the mechanisms are in modular design. A slope face is arranged at the inner bottom of a hopper of the automatic feeding and discharging device, a material passing opening communicating with the lower end of the slope face is arranged on the side wall of the hopper, and shifting sheets capable of rotating up and down are arranged below the material passing opening. An elastic reset mechanism is arranged between the bottom faces of the shifting sheets and the outer side face of the bottom of the hopper. A rotating workbench is arranged below the shifting sheets, a rotating disc shaft is arranged on the rotating workbench, and the two ends of the rotating disc shaft are fixedly connected with rotating discs. In the process that the rotating disc shaft drives the rotating discs to rotate outwards, pipes falling onto clamp grooves of the rotating discs from the shifting sheets through self gravity can arrive at a feeding station, a machiningstation and a discharging station in sequence. According to the pipe expanding method, the full-automatic pipe expanding machine is adopted for expanding. The automation degree is improved, meanwhile,cost is reduced, the expanding quality is controlled more stably, and production efficiency is higher.

Description

technical field [0001] The invention belongs to the field of mechanical processing equipment, and in particular relates to an equipment and a flaring method for automatically flaring pipes such as steel pipes and copper pipes. Background technique [0002] Flaring machines are widely used in the field of machinery manufacturing. The wall thickness of the pipes used in the air-conditioning home appliance industry is relatively thin, generally between 1-1.5mm. In this field, a special pipe flaring machine is generally used for flaring. Due to the thin wall thickness of the pipe and the good ductility of copper, it can be easily expanded by using the punch reaming method. Due to the advantages of high efficiency and good flaring quality, the pipe flaring machine has been widely used in the air-conditioning industry. At present, there are many manufacturers specializing in the design and production of various types of pipe flaring machines. Existing pipe flaring machines have ...

AI Technical Summary

Problems solved by technology

Existing pipe flaring machines have different degrees of automation, different principles, different flaring diameters, and different mechanical properties.

However, these processes have the following problems: the traditional pipe flaring machine has a low degree of automation, and manual loading and unloading leads to low production efficiency; a large amount of manpower is required, resulting in poor product quality stability; high production costs are not conducive to mass production

[0004] (1) For large-scale automatic belling machines, due to the relatively complicated design and the collection of knowledge of mechanical, electrical, microelectronics and other disciplines, the price of belling machines is generally high. Compared with traditional pipe belling equipment, the cycle time The use cost and maintenance cost are also higher. For enterprises, it is more expected to reduce this cost

[0005] (2) At present, some manual pipe flaring machines still in use have unreliable performance, poor flaring quality, high scrap rate and low efficiency

The quality of the production workpiece is determined by the state and experience of the workers, which requires a high quality of the workers, and at the same time, the labor intensity is very high for the workers
