Tank bottom head automatic welding device and control method thereof

Abstract

The invention discloses a tank bottom head automatic welding device and a control method thereof. The device comprises a main support playing a supporting role, the main support comprises a base, a sliding rod perpendicular to the base is arranged on the base, a control cabinet is arranged at the left side of the sliding rod, a welding bracket is connected to the sliding rod in a sliding mode, a welding device is arranged on the welding bracket, a welding slag cleaner is arranged below the welding bracket, a plastic tank is arranged at the right side of the welding device, an up-down adjustingdriving motor is arranged at the top of the sliding rod, and a control end of the welding device, a control end of the welding slag cleaner and a control end of the up-down adjusting driving motor are separately and electrically connected with the control cabinet. According to the device and the method, the problems that in the prior art, when the traditional welding device for welding a barrel and a bottom head is used, the pressure applied by a welding gun is insufficient, the welding speed is not uniform, and the welding slag treatment process is time-consuming after welding are solved. According to the device and the method, advantages of short operation time, low operation cost, high operation efficiency, high overall gains for customers and the like are achieved.

Description

technical field [0001] The present invention relates to a welding equipment, in particular to an automatic welding equipment for tank bottom head and its control method. Background technique [0002] The bottom of the plastic tank is in the form of a head, which is a relatively common form of tank installation. The weld between the cylinder and the bottom of the head is the point with the greatest stress and the weakest point, so the welding strength here is particularly important. At the present stage in China, the connection form of the tank body and the bottom head adopts traditional hot gas welding, selects a suitable pre-processed welding rod, and uses a hand-held welding torch to manually control continuous welding to apply pressure and a suitable welding speed for welding. Because the part is welded in an arc-shaped bead, the position of the welding torch must be adjusted continuously during the welding process to ensure the angle of the weld seam, the direction of th...
