A rotary table flame welding machine and its welding method

Abstract

The invention discloses a rotary-disc flame welding machine and a welding method thereof. The rotary-disc flame welding machine comprises a machine body, wherein a rotary disc, an electric control box, a gas control box, a wire feeding mechanism and a welding heating gun are arranged on the top surface of the machine body; the wire feeding mechanism and the welding heating gun are both connected with a first cylinder through a first piston rod separately; a ratchet wheel is connected to the rotary disc through a rotary shaft; a second cylinder is horizontally arranged at one side of the ratchet wheel; the second cylinder is connected with a pawl through a second piston rod; a wire storage mechanism is arranged in the machine body; and a charge mechanism and a discharge mechanism are arranged on the side surface of the machine body. The welding method thereof comprises the following steps: clamping location for the charge mechanism, clamping location for the discharge mechanism, location for the wire feeding mechanism and the welding heating gun, and the trial running of the flame welding machine. The welding method disclosed by the invention is beneficial to realizing the automatic machining and production of the flame welding machine, thereby improving the welding accuracy; and temperature interference among welding points is eliminated, and the small heating range and obvious gradient temperature phenomenon of a traditional fixed welding gun is eliminated with regard to products with complex structures and large sizes.

Description

technical field [0001] The invention relates to a turntable flame welding machine and a welding method thereof. Background technique [0002] Flame welding machine is a kind of welding equipment used for welding process. During the welding process, gas flux can be directly used instead of traditional manual adding of borax to improve the lubricity and fluidity of brazing, so as to reduce the generation of pores and improve the weld resistance. tensile strength. [0003] In the prior art, the wire feed gun and heating gun on the flame welding machine are generally fixed, and the position of the gun head cannot be flexibly adjusted, so the flexibility of use is poor, and the welding accuracy cannot be improved. Due to the small heating range, there is an obvious gradient temperature phenomenon. Contents of the invention [0004] The purpose of the present invention is to provide a technical scheme of a turntable flame welding machine and its welding method in view of the d...
