Device for automatically measuring and inkjet-marking steel tube

Abstract

The invention relates to a device for automatically measuring and inkjet-marking a steel tube, belonging to detecting instruments. The device is characterized in that: guide rails are arranged in parallel on a base; a rack and a guide rail sliding block are arranged on the guide rails; a driving motor and a speed reducer are arranged on the guide rail sliding block; a gear engaged with the rack is arranged on a shaft of the speed reducer; vertical columns of a portal frame are provided with a first sliding block; a second sliding block is arranged on a cross beam; an inkjet-marking mobile table is vertically arranged on the second sliding block; an inkjet-marking head and an ink box are arranged on the inkjet-marking mobile table; the ink box is connected with the inkjet-marking head; a sensor mobile table is arranged on the portal frame; a sensor is arranged on the sensor mobile table; the driving motors are arranged on the inkjet-marking mobile table and the sensor mobile table; and the driving motors, the sensor and the inkjet-marking head are connected with an electric control system through cables. The device for automatically measuring and inkjet-marking the steel tube can be used for detecting the length, the diameter, the linearity and the roundness of the steel tube and inkjet-marking the steel tube, and has the advantages of high reliability, high detection precision, good inkjet-marking effect and reduced labor intensity.

Description

technical field [0001] The invention relates to an automatic measuring and marking device for steel pipes, which belongs to testing instruments. Background technique [0002] With the advancement of seamless steel pipe forging technology and seamless steel pipe rolling technology, domestic large-diameter seamless steel pipe production has developed by leaps and bounds. After the country implemented the western development strategy, the investment scale exceeded any previous large-scale projects. The national "Eleventh Five-Year Plan" major project 360MN vertical extrusion machine was successfully developed and settled in NHI, so it is suitable for the natural environment in the west and large-scale seamless steel pipes. Production will be favored by the market. The length, diameter, straightness, and roundness of the finished steel pipes are tested before leaving the factory, and inkjet marking is carried out on the steel pipes according to the test results. Since the larg...

AI Technical Summary

Problems solved by technology

Since the large-diameter thick-walled seamless steel pipes produced by the 360MN vertical extrusion machine have a maximum diameter of Φ1400mm, a length of 12m, and a weight of 25 tons per piece, the use of measuring tools such as steel tapes and micrometers for manual detection is inefficient and the detection accuracy cannot be guaranteed. , and manual spraying has disadvantages such as low efficiency and unsightly printing effect, it is difficult to meet the requirements of mass production
