The Upgrade and Improvement of The Notch Cutting Machine

The notch cutting machine adopts discharge processing, which can complete the standard engraving manufacture of longitudinal and transverse artificial groove, flat bottom hole, rectangular groove and through hole. Due to the deterioration of the using environment of steel pipes, people put forward more and more stringent requirements for the notch cutting machine. Next, as one of the professional companies in the automation industry, Nanjing BKN Automation System Co.,LTD will introduce the upgrade of the notch cutting machine.

1. The space size of the nose of the notch cutting machine is reduced

The main technical index of the original notch cutting machine is to realize the engraving process. The operation of the steel pipe testing in special working environment is not considered. The nose of the original notch cutting machine is large, taking up a large space, so it is impossible to carve the small-diameter steel pipe. However, after the improvement, not only the geometric size of each workpiece is reduced, but also some accessories which are not necessary in the nose of the notch cutting machine are installed on the interconnected external equipment, which can realize the function of small-diameter engraving.

2. Redesign the working arm of the notch cutting machine

The original notch cutting machine only sets a positioning base on the pipe body, which is used to fix the parts and adjust the parallelism with the pipe axis. The improved notch cutting machine uses the working arm to extend into the pipe body, and the operation is carried out externally through the pipeline circuit, which is convenient for the observation and adjustment of the nose of the notch cutting machine in the pipe body.

3. Through the improvement of the circuit and hydraulic system, the precise remote operation is realized on the notch cutting machine

In order to ensure the accuracy of the standard manual engraving, the improved notch cutting machine is equipped with appropriate circuit and hydraulic system. In addition, the alignment and operation of the relative position between the electrode and the tube body have been improved to achieve precise positioning, feed process adjustment and other processes, which meet the standard specifications and users' requirements.
