Vertical milling machine for arc striking and extinguishing plates

Abstract

The invention discloses a vertical milling machine for arc striking and extinguishing plates. A forward and backward moving guide rail and a forward and backward moving oil cylinder are fixed on a base of the vertical milling machine; a sliding bottom plate is arranged on the forward and backward moving guide rail; a piston end of the forward and backward moving oil cylinder is hinged on the sliding bottom plate; a left and right moving guide rail and a left and right servo system are fixed on the sliding bottom plate; a machine body is arranged on the left and right moving guide rail; the left and right servo system is connected with the machine body; and a vertical milling table lifting device is fixed on the machine body, a vertical milling head is fixed on the lifting device, the upper end face of a vertical milling table is provided with a rectangular milling cutter groove, and a milling cutter on the vertical milling head is positioned above the rectangular milling cutter groove. The vertical milling machine for removing the arc striking and extinguishing plates at two ends of a butt-jointed seam by using the metal cutting principle and adopting a milling method can effectively reduce heat on two sides of a steel strip, and the internal tissue of the steel strip is not changed; and at the same time, the two sides of the processed steel strip are smooth and regular, and the vertical milling machine can ensure the tissue performance and product quality of continuous oil pipes at the butt-jointed steel strip and produce qualified continuous oil pipe products.

Description

technical field [0001] The invention relates to an end milling machine for extinguishing arc plates. Background technique [0002] In order to ensure the quality of the butt welds of steel strips and steel plates, the two ends of the butt welds are usually butt-jointed or clamped, and the arc-extinguishing plates are clamped. For butt welds that are only for priming or that can be reasonably removed through process control, the quality of the weld edges is not high. But for the steel strip butt joint of coiled tubing, it is required that the quality of the butt weld of the steel strip has no defects. Any defect of the coiled tubing steel strip used for production after butt joint will cause the product to be degraded or even become a waste product. Therefore, on the one hand, it is necessary to strictly control the welding quality of the butt weld, and on the other hand, it is also necessary to control the influence on the edge quality of the weld after the removal of the l...

AI Technical Summary

Problems solved by technology

At present, the commonly used removal methods for the lead and arc extinguishing plates are aerobic acetylene flame cutting method, shearing method, hammer hammering method, wire cutting method, etc. The side edge is damaged or the structure of the steel strip is changed, which cannot meet the technical requirements of the coiled tubing production for the steel strip
