Problems solved by technology

[0002] There are many existing methods for making long tubes, but there are some problems, such as insufficient strength of long tubes, insufficient hole precision of long tubes, and overall shape of long tubes that do not meet the requirements, etc. Such long tubes cannot meet the needs of the market. Demand is not conducive to the smooth progress of production, so in order to better make the long tube meet the requirements, a processing method is proposed to solve this problem

Embodiment 2

[0012] Embodiment two: the first step: saw diameter φ 60mm with sawing machine, the long pipe of length 701mm, the diameter and the length of long pipe are preliminarily determined; 697mm; Step 3: Polish the long tube surface, the surface roughness is Ra12.5; Step 4: Inspect the processed long tube and put it into storage. Sampling inspection of appearance and size, 10 samples for appearance and 5 samples for size.

Embodiment 3

[0013] Embodiment three: the first step: use sawing machine to saw diameter φ 60mm, the long pipe of length 701mm, the diameter and the length of long pipe are preliminarily determined; 697.8mm; Step 3: Polish the surface of the long tube, the surface roughness is Ra12.5; Step 4: Inspect the processed long tube and put it into storage. In the fourth step, when inspecting the long tube, Carry out appearance sampling inspection and size sampling inspection, 10 appearance sampling inspections and 5 size sampling inspections.

[0014] The processing technology of a long tube of the present invention satisfies the production requirements through sawing machine sawing, machine tool processing and surface polishing, improves the precision and strength of the produced long tube, makes it meet the requirements, reduces the defective rate, and reduces the production cost.

Abstract

The invention discloses a long pipe machining technology. The long pipe machining technology is characterized by comprising the steps that firstly, a sawing machine is used for sawing a long pipe, wherein the diameter phi of the long pipe is 60 mm, and the length of the long pipe is 701 mm; secondly, a machine tool is used for conducting length machining on the long pipe, and the length of the long pipe is made to be 697+ / -0.8 mm through finishing machining; thirdly, the surface of the long pipe is polished, and the surface roughness is Ra12.5; fourthly, the machined long pipe is inspected and put into a warehouse. According to the long pipe machining technology, production requirements are met through sawing of the sawing machine, machining of the machine tool and surface polishing, the precision and the strength of the produced long pipe are improved, the long pipe can meet the requirements, the defective rate is lowered, and the production cost is reduced.

Description

technical field [0001] The invention relates to a processing technology of a long pipe, which belongs to the technical field of mechanical processing. Background technique [0002] There are many existing methods for making long tubes, but there are some problems, such as insufficient strength of long tubes, insufficient hole precision of long tubes, and overall shape of long tubes that do not meet the requirements, etc. Such long tubes cannot meet the needs of the market. Demand is not conducive to the smooth progress of production, so in order to better make the long tube meet the requirements, a processing method is proposed to solve this problem. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a processing technology for long pipes with precise processing and meeting production requirements. [0004] The technical solution of the present invention is realized like this: a kind of p...
