Segmented milling positioning device and positioning method for blade of welded pipe edge milling machine

Abstract

The invention provides a segmented milling positioning device and positioning method for a blade of a welded pipe edge milling machine. The segmented milling positioning device comprises a machine frame, wherein a plurality of rotatable facing cutters are arranged on the two sides of the machine frame; transmission devices are arranged on the two sides of the machine frame and can drive the facing cutters to move in the horizontal direction and the vertical direction, horizontal direction movement is a cutting feeding direction of the facing cutters, and vertical direction movement is a cutter feeding or retracting direction of the facing cutters; and the two facing cutters on the same side of the machine frame are driven by an independent third motor and can be independently used or alternately used, so that a milling cutter device is not stopped, and the two facing cutters on the same side can be vertically spliced into one facing cutter. One blade can be divided into an upper half section and a lower half section for use. The two facing cutters on the same side can be used independently and alternately, when one facing cutter is damaged, the other facing cutter works, the damaged facing cutter can be overhauled, and the milling cutter device is not stopped. And the two facing cutters on the same side can be spliced up and down to form a facing cutter milling thick plate, so that the device is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of edge milling of edge milling machines, in particular to a positioning control device and a positioning calculation method for segmental milling of blades of high-frequency welded pipe edge milling machines. Background technique [0002] The role of the high-frequency welded pipe edge milling post is: after the left and right edges of the steel strip enter the edge milling machine, the left and right edge milling machine cutterheads on the edge of the steel strip rotate, and the blades on the cutterhead perform blunt edge milling on the edge of the steel strip. The steel plate selected for high-frequency welded pipe is generally thin, and its thickness is generally less than half of the thickness of its milling blade. At present, the common method of positioning and milling control of the cutterhead of the high-frequency welded pipe edge milling machine in my country is: through a switch value limit to sense whether...

AI Technical Summary

Problems solved by technology

However, this solution has the problem of not being able to displace the cutter head in the horizontal and vertical directions. The process of entering and withdrawing the tool requires manual operation, and will cause large errors, so it cannot be used for steel milling with high precision requirements.

After the blade is damaged, it needs to be shut down for maintenance, and the process of replacing the cutter head or blade is also difficult, which causes a waste of steel costs and a large amount of cost loss due to the shutdown of the assembly line. It is not suitable for industrial assembly line factories that cannot be shut down, and this equipment can only be used for Milling a steel plate with a specific thickness cannot flexibly change the thickness of the steel plate, and it is not suitable for steel with different thicknesses from different manufacturers. It cannot be widely used in large factories, and its use has limitations.
