Multifunctional pipe connecting flange automatic welding and cutting machine

Abstract

The invention provides a multifunctional pipe connecting flange automatic welding and cutting machine, and relates to an automatic welding and cutting machine. The multifunctional pipe connecting flange automatic welding and cutting machine overcomes the defects that in a manufacturing process of a pressure container, welding between a connecting pipe and a flange mainly depends on manual operation, a weld pass is easily uneven when formed or a welding line is too full or the welding height is not enough, and production efficiency is low. The multifunctional pipe connecting flange automatic welding and cutting machine is characterized by comprising a circumference rotating system, a linear travelling system and a control system used for controlling the circumference rotating system and the linear travelling system, and the circumference rotating system and the linear travelling system are arranged on a machine frame. The circumference rotating system comprises a circumference stepping motor, a clamping plate and a vertical rotating device, wherein the clamping plate is connected with an output shaft of the circumference stepping motor. The linear travelling system comprises a linear steeping motor, a pulling board, a left-and-right guide device and a clamping arm, wherein the pulling board is connected with the linear steeping motor, the left-and-right guide device is matched with the pulling board, and the clamping arm is connected with the pulling board and used for clamping a welding gun. The control system is connected with the circumference stepping motor and the linear steeping motor. According to the technical scheme, welding efficiency is improved, the welding line is level, and the pipe orifice of the cylinder connection pipe can be cut in a curve mode.

Description

technical field [0001] The invention relates to an automatic welding and cutting machine. Background technique [0002] In the manufacturing process of pressure vessels, there are a large number of nozzle flanges that need to be welded and finally connected to the cylinder. At present, the welding between the nozzle and the flange mainly relies on manual arc welding or manual argon arc welding, and usually relies on the butt joint of the nozzle and the flange. The rotation of the weld seam on the horizontal plane keeps the weld seam in a flat welding position to complete the welding of the entire circumferential weld seam. Due to the manual operation of the weld bead, the shape of the weld is inevitably affected by personal skills, resulting in defects such as uneven bead shape, over-full weld bead or insufficient weld height. At the same time, continuous intermittent welding is required Rotate the workpiece to ensure that the welded position is in a flat welding state. Mul...

Problems solved by technology

Due to the manual operation of the weld bead, the shape of the weld is inevitably affected by personal skills, resulting in defects such as uneven bead shape, over-full weld bead or insufficient weld height. At the same time, continuous intermittent welding is required Rotate the workpiece to ensure that the welding position is in a flat welding state. Multiple intermittent arc strikes are likely to cause welding defects in the joint and also affect production efficiency.
