Cutting device for intersecting line of intersecting pipelines of different dimensions and machining method thereof

Abstract

The invention discloses a cutting device for an intersecting line of intersecting pipelines of different dimensions. The cutting device for the intersecting line of the intersecting pipelines of different dimensions comprises a supporting device supporting a pipeline to be machined. A support is installed on the supporting device. A template workbench is installed on the support. A motor is installed on the template workbench and connected with a transmission main shaft. A cross rod is fixedly connected to the transmission main shaft. The cross rod is sleeved with a guide sleeve. The guide sleeve is connected with a cutting torch support through a compression spring. The cutting torch support is connected with a cutting torch. A template is arranged on the lower side of the template workbench. The template is provided with an arc concave face identical with the pipeline to be machined in radius. When the pipeline to be machined needs to be cut, the cutting radius is adjusted through a locking device, the template is adjusted to be at an appropriate height, the top end of the cutting torch support is located on the arc concave face, the motor is started, and the pipeline to be machined is cut through the cutting torch. The cutting device can machine the intersecting line of the intersecting pipelines of different dimensions through a female die, the profile of the female die is easy and convenient to machine, and the cutting device for the intersecting line of the intersecting pipelines of different dimensions has the advantages of being high in machining quality, low in production cost and the like.

Description

technical field [0001] The invention relates to cutting equipment and a processing method suitable for intersecting lines of intersecting pipelines of different sizes, and belongs to the field of processing. Background technique [0002] Intersecting wire cutting equipment is widely used in the cutting and processing of pipeline structural parts in construction, chemical industry, shipbuilding, mechanical engineering, metallurgy, electric power and other industries. The cutting head in the intersecting wire cutting equipment has the functions of walking the intersecting wire trajectory and cutting. The mechanism has high requirements for operating sensitivity and accuracy, so the structure is relatively complicated, and it is the core part of the intersecting wire cutting equipment. [0003] At present, in the mechanical processing process, there are three types of existing pipe cutting methods: manual cutting, semi-automatic cutting machine cutting and intersecting wire cut...

Problems solved by technology

The first type of manual cutting has the advantages of flexibility, convenience, simple operation, and low cost, but manual cutting has poor quality, large dimensional errors, large material waste, and large follow-up processing workload. At the same time, the working conditions are harsh, labor intensity is high, and production efficiency is low.

The second type of semi-automatic cutting machine cutting, although it reduces the labor intensity of workers, its function is simple, and it is only suitable for cutting parts with more regular shapes.

[0004] The second type of semi-automatic cutting machine mostly adopts the male mold control method. The structure of the male mold depends on the parameters such as the size and intersection position of the pipeline to be processed and the intersecting pipeline, and has a strict corresponding relationship, resulting in a wide variety of male molds for intersecting pipelines with different diameters. Moreover, the surface of the positive model is complex and difficult to process, which restricts the application range and market of semi-automatic cutting machines.
