Externally-square and internally-circular coil pipe and machining device thereof

Abstract

The invention provides an externally-square and internally-circular coil pipe and a machining device thereof, and relates to the technical field of externally-square and internally-circular devices, the machining device is mainly composed of a machining table, a cutting machine, a coil pipe body and a fixing device, the cutting machine is arranged at the upper end of the machining table, the coil pipe body is placed at the end, close to the cutting machine, of the machining table, and the fixing device is arranged at the end, opposite to the cutting machine, of the machining table; and the fixing device comprises a sliding rail, the bottom end of the sliding rail is welded to the machining table, the sliding rail is in an I shape, the end, away from the machining table, of the sliding rail is slidably connected with two connecting plates, the ends, away from the sliding rail, of the connecting plates are slidably connected with two clamping plates, and the ends, close to each other, of the two clamping plates are fixedly connected with first springs. According to the externally-square and internally-circular coil pipe and the machining device thereof, the fixing device is arranged, and the problems that in the existing cutting process, a pipe is manually held by hand, one end of the pipe is placed into a cutting machine to be cut, due to instability of manual holding, pipe cutting deviates, and the end opening of the cut pipe is not smooth enough are solved.

Description

technical field [0001] The invention relates to the technical field of outer square inner circle, in particular to an outer square inner circle coil pipe and a processing device thereof. Background technique [0002] The cross-section of the pipe is usually circular, and there are special-shaped pipes made of non-circular cross-section. Some metal pipes such as steel pipes and copper pipes can also be used as structural or decorative elements. There are many materials for making pipes, and metal and non-metal materials are commonly used. As a kind of pipe, coil pipe is a spiral pipe. [0003] The coil will be processed and cut before use, so as to meet the required length requirements. In order to facilitate real-time adjustment of the cutting length, the existing cutting needs to be manually hand-held to feed the pipe and support the pipe to avoid shaking. One end of the pipe is put into the cutting machine. When cutting, due to the slight muscle shaking in the process of...

Problems solved by technology

[0003] The coil will be processed and cut before use, so as to meet the required length requirements. In order to facilitate real-time adjustment of the cutting length, the existing cutting needs to be manually hand-held to feed the pipe and support the pipe to avoid shaking. One end of the pipe is put into the cutting machine. When cutting, due to the slight muscle shaking in the process of human support, it is easy to make the pipe cutting deviation, resulting in the end of the cut pipe is not smooth enough, it is particularly important to develop a pipe with a fixed function based on the above problems
