Bending equipment for stainless steel pipeline fitting machining

Abstract

The invention discloses bending equipment for stainless steel pipeline fitting machining. The bending equipment for stainless steel pipeline fitting machining comprises a stainless steel pipe and a pipe bending frame, wherein a pipe bending box is arranged on the pipe bending frame, and a fixing mechanism for fixing the stainless steel pipe, a pipe bending mechanism for pipe bending operation andan ice core generating mechanism are arranged in the pipe bending box; the ice core generating mechanism comprises a refrigerating mechanism arranged in the pipe bending box, a first plug is detachably connected to one end of pipe bending of the stainless steel pipe, a second plug is detachably connected to the other end of the stainless steel pipe, a water draining pipe is connected to the firstplug, a first valve is arranged on the water draining pipe, a pipe opening of the water draining pipe is higher than the position of the stainless steel pipe, a connecting pipe is connected to the second plug, a second valve is arranged on the connecting pipe, a liquid supplying box is connected to the connecting pipe, and a freezing liquid is arranged in the liquid supplying box. Through the above arrangement, an ice column formed after water freezes is used as a core rod, so that the advantage of the efficient use is achieved, and the pipe bending quality can be improved.

Description

technical field [0001] The invention relates to the field of pipeline manufacturing, in particular to a bending equipment for processing stainless steel pipeline fittings. Background technique [0002] The bent pipe is bent by a complete set of bending equipment, which is divided into two processes: cold simmering and hot pushing. No matter what kind of machinery and equipment and pipelines, most of them use elbows, which are mainly used for oil, gas, liquid, engineering bridge construction, etc. [0003] At present, according to the different needs of the market, it is often necessary to bend the pipe fittings into various shapes. According to the different bending process, it can be divided into two methods: cold bending and hot bending. According to the action mode of external force, the cold bend can be divided into several forms: pressure bending, rolling bending and stretch bending. Bending and rolling are difficult to control during bending, and the quality of the ...

Problems solved by technology

For this reason, the mandrel device is used on the pipe bending machine for the pull-type pipe bending machine. When bending the pipe, in order to reduce the friction between the mandrel and the inner wall of the pipe, lubricating oil is often applied in the pipe, which will pollute the inner wall of the pipe.

Because the shape of the mandrel has a great influence on the quality of the bend, the manufacture of the mandrel is complicated and costly

In addition, when bending special-shaped pipe fittings, it is often impossible to unload the pipe after the pipe is bent, and it needs to be corrected after the pipe is unloaded.
