Automatic cutting machine for end face of elbow

Abstract

The invention discloses an automatic cutting machine for an end face of an elbow, and aims to provide an automatic cutting machine with functions of radially and transversely adjusting a cutting torch according to the diameter of the end face of the elbow. The automatic cutting machine comprises a traveling trolley capable of moving along a steel rail, wherein a vertical column seat and a vertical column are arranged above the traveling trolley; the upper end of the vertical column is sleeved into a transmission box; speed reducers and motors are arranged above the transmission box; a liftingbox is arranged below the transmission box, and is sleeved into the vertical column; a screw rod is inserted into the vertical column and the transmission box; a screw nut is arranged in the lifting box, and is sleeved on the screw rod; a hollow shaft is connected with the speed reducers through a connection seat; the end of the hollow shaft is in bolted connection with a radial dovetail sliding block mechanism; the radial dovetail sliding block mechanism is connected with the speed reducer through the connection seat, and is connected with a transverse dovetail sliding block mechanism through a connection frame; each motor is connected with the corresponding speed reducer; a cutting torch assembly is fixed at the end of a cutting torch fixing rod; and the air inlet pipe opening of the cutting torch assembly is connected with an oxygen band and an acetylene band respectively.

Description

technical field [0001] The invention relates to an automatic elbow end face cutting machine, in particular to an elbow end face automatic cutting machine which adopts a radial dovetail slider mechanism and a transverse dovetail slider mechanism to adjust the cutting torch, and belongs to the technical field of mechanical processing equipment. Background technique [0002] When transporting gas and liquid in electric power, chemical industry and other industries, elbows are required for the interconnection of pipelines. At present, when the elbow is processed, the pipe is first subjected to hot-press bending and forming. After the hot-press bending is formed, the remaining straight sections at both ends of the elbow are manually marked with tools such as squares and wire pendants. After manual marking, manual hand-held cutting is used. The torch cuts the straight section along the drawn secant line, and after the straight section is cut, the groove processing equipment is use...

AI Technical Summary

Problems solved by technology

In the process of cutting the straight section of the elbow, manual operation will cause the incision to be irregular, which will increase the difficulty and processing time of the subsequent elbow beveling process; at the same time, manual scribing and cutting will lead to high labor intensity and high product productivity. low production cost
