Automatic lettering scribing machine for cast pipe

Abstract

The invention discloses an automatic lettering scribing machine for a cast pipe. The automatic lettering scribing machine comprises a lettering device (1), wherein a scribing device (2) and a positioning device (3) are arranged on two sides of the lettering device (1). According to the automatic lettering scribing machine, after being positioned, the cast pipe conveyed by a production transmission line can be driven to rotate along the own axis, lettering on the outer tube wall of the cast pipe along the axis of the cast pipe is performed in the process of rotating the cast pipe, and scribing at the required position of the faucet end of the cast pipe is performed, so that the technical current situation of manual lettering in the conventional process is changed, the production is accelerated, the labor of lettering and scribing operation is saved, the operating cost of enterprises is reduced, and the automatic lettering scribing machine has a wide market prospect.

Description

technical field [0001] The invention relates to a device used in the metal casting industry, in particular to an automatic printing and marking machine for cast pipes. Background technique [0002] After the bitumen spraying on the outer surface of the cast pipe is completed, after drying, it enters the packaging machine. It is necessary to draw a line at the socket of the cast pipe. The purpose is to meet the needs of the installation of the cast pipe. According to the size (nominal diameter) of the pipe, draw the installation line at different positions of the socket end. The printing is to spray the logo on the body of each pipe approximately along the center of the pipe length direction. At present, the printing of cast pipes on the production line is manually sprayed or painted by templates. This method has low productivity and requires operators to increase the cost of enterprise operations. The formwork drives the pipe to roll over the formwork on the track, and at ...

AI Technical Summary

Problems solved by technology

At present, the printing of cast pipes on the production line is manually sprayed or painted by templates. The productivity of this method is low, and operators must be arranged, which increases the cost of enterprise operation; there is also a method of installing and fixing under the track. The formwork drives the pipe to roll over the formwork on the track, and at the same time achieves the purpose of printing on the outer surface of the cast pipe. In this way, the damage to the painted surface of the outer wall of the cast pipe is relatively serious, and there are still certain defects.

And there is no device on the market that can simultaneously print on the outer wall of the cast tube and draw a line at the spigot end of the cast tube
