Bending equipment for processing stainless steel pipe fittings

Abstract

The invention discloses a bending equipment for processing stainless steel pipe fittings, which comprises a stainless steel pipe and a pipe bend frame. The pipe bending mechanism for pipe bending operation, and the ice core generating mechanism; the ice core generating mechanism includes a refrigeration mechanism arranged in the pipe bending box, one end of the stainless steel pipe for bending is detachably connected with a first plug, and the other end is detachably connected There is a second plug, the first plug is connected with a water discharge pipe, the water discharge pipe is provided with a first valve, the nozzle of the water discharge pipe is higher than the position of the stainless steel pipe, the second plug is connected with a connecting pipe, and the connecting pipe is provided with a For the second valve, the connecting pipe is connected to a liquid supply tank, and the liquid supply tank is provided with refrigerated liquid. Through the above arrangement, using the icicle formed after the water freezes as the mandrel has the advantage of high efficiency and can improve the quality of the pipe bend.

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.
