Embodiment Construction

[0009] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0010] Such as figure 1 As shown, the present invention mainly consists of cutting torch 1, gas pipe 2, preheating oxygen pipe 3, cutting oxygen pipe 4, gas pipe solenoid valve 5, preheating oxygen pipe solenoid valve 6, cutting oxygen pipe solenoid valve 7, and exhaust gas discharge electromagnetic valve. Valve 8, muffler 9 and exhaust pipe 10 are composed. Gas pipe 2, preheating oxygen pipe 3 and cutting oxygen pipe 4 are all connected to cutting torch 1 respectively; On hot oxygen pipe 3, cutting oxygen pipe 4. Tail gas discharge pipe 10 communicates with cutting oxygen pipe 4 inner chambers, tail gas discharge electromagnetic valve 8 is installed on tail gas discharge pipe 10, and muffler 9 is installed on the exhaust port of tail gas discharge solenoid valve 8 to eliminate the abnormal sound when exhaust gas is discharged. In order to make th...

Abstract

The invention discloses an automatic discharging device for a flame cutting tail gas, and belongs to flame cutting equipment. The device comprises a cutting gun, a gas pipe, a preheating oxygen pipe, a cutting oxygen pipe, a gas pipe electromagnetic valve, a preheating oxygen pipe electromagnetic valve, and a cutting oxygen pipe electromagnetic valve, wherein the gas pipe, the preheating oxygen pipe and the cutting oxygen pipe are respectively connected with the cutting gun; the gas pipe electromagnetic valve controls the gas pipe; the cutting oxygen pipe electromagnetic valve controls the cutting oxygen pipe; the cutting oxygen pipe electromagnetic valve controls the cutting oxygen pipe; the cutting oxygen pipe is connected with a tail gas discharging pipe which is communicated with the cavity of the cutting oxygen pipe; a tail gas discharging electromagnetic valve for controlling the discharging of a tail gas is arranged on the tail gas discharging pipe; and a silencer is arranged at an exhaust port of the tail gas discharging electromagnetic valve. At the end of cutting, the gas pipe electromagnetic valve, the preheating oxygen pipe electromagnetic valve and the cutting oxygen pipe electromagnetic valve are closed and the tail gas discharging electromagnetic valve is opened to form a pressure difference between the two ends of the tail gas discharging pipe, so that the tail gas in the cutting oxygen pipe is discharged. The device has the advantages that: the problem of discharging the tail gas in flame cutting is solved; redundant cutting at an ending position of a workpiece is avoided; and the workpiece cutting quality is improved.

Description

technical field [0001] The invention relates to a flame cutting device, in particular to a flame cutting tail gas automatic discharge device. It is mainly used to solve the exhaust gas emission problem at the end of flame cutting. Background technique [0002] Flame cutting is a widely used material cutting method. But at the end of the flame cutting, because there is still residual gas in the gas pipe and the cutting oxygen pipe, the kerf of the workpiece to be cut is still in the molten pool state, that is, a part of the material will be cut off at the end of the workpiece, so that The workpiece being cut produces as figure 2 The defects shown affect the quality of flame cutting. Contents of the invention [0003] The invention provides an automatic discharge device for flame cutting tail gas, aiming at solving the problem of tail gas discharge during flame cutting and improving the quality of flame cutting. [0004] The present invention is realized by the following...
