Description

A fully automatic pipe cutting machine

technical field

The invention relates to the technical field of pipe processing equipment, in particular to an automatic pipe cutting machine.

Background technique

Pipes are widely used materials in construction engineering, such as water supply pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. Different pipe fittings use different pipe materials, and the quality of the pipe directly determines the quality of the pipe fittings. With the development of the market towards high speed, high precision and high quality, the automation, high efficiency and precision of cutting quality of pipe cutting mechanism are inevitable trends.

Most of the existing pipe cutting equipment in the industry are traditional pure manual cutting or pure mechanical cutting. Pure manual cutting equipment requires manual operation by the operator, so its operation process is affected by the operator's subjective factors, which may reduce the cutting quality and cutting accuracy. In addition, the use of the grinding wheel saw may also cause injury to the operator; and the mechanical cutting equipment used in pure mechanical cutting is usually more complicated, requiring the operator to be proficient in the operation method of the equipment, and the requirements for the operator are higher. A good pure mechanical cutting equipment is expensive and expensive to maintain.

At present, conventional pipe cutting machines generally use the following methods to cut pipes:

1. Manual feeding, use a flat ruler to determine the cutting length of the pipe fittings. Due to manual feeding, the operator can visually measure the length with his eyes. Due to the different viewing angles, the error in determining the length is at least ±0.8mm. Such an error cannot meet the requirements of producing high-precision products.

2. Fix the components of the grinding wheel cutting machine, and the operator pushes the hose to cut off. The straightness of the operator's hand push directly affects the straightness of the incision of the pipe cutting. The straightness of the incision of the pipe cutting in this way is low, which cannot meet the requirements of high-precision products.

3. The cutting work requires two workers to cooperate to complete the operation, which is low in efficiency, slow in speed, and labor-intensive for operators.

Therefore, it is necessary to improve the structure of the existing pipe cutting machine.
