A split-type tool linear laser welding equipment and using method thereof

Abstract

The invention discloses a split-type tool linear laser welding equipment and a method of using the same, belonging to the field of tool welding equipment, a split-type tool linear laser welding equipment and a method of using the same. The position of the welding seam is initially limited, and then through the setting of two heat-resistant pressure plates, the edge of the knife back and the edge of the knife edge to be welded is squeezed and positioned, and at the same time, the flat warping limit layer in the welding gap of the knife is matched. , when the back of the knife is inserted into the U-shaped flat warping limiting layer to generate a pressing force on it, the internal gap-filling particles are squeezed into the warped gap, that is, the gap in the warped part is filled, so that the back of the knife is warped. Soft to rigid positioning of the starting part makes the blade back in a stable state as a whole, and it is not easy to shake during welding, thereby effectively improving the linear integrity of the welding seam and improving the welding effect.

Description

technical field [0001] The invention relates to the field of tool welding equipment, and more particularly, to a split-type tool linear laser welding equipment and a method for using the same. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is of thermal conduction type, that is, the surface of the workpiece is heated by laser radiation, and the surface heat diffuses to the interior through thermal conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse and other parameters to melt the workpiece and form a specific molten pool. Due to its unique advantages, it has been successfully used in the precision welding of micr...

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the object of the present invention is to provide a split type tool linear laser welding equipment and its use method. It first adjusts the position of the weld seam through the cooperation of the welding seam positioning protrusion and the long heat-gathering groove. Carry out the preliminary limit, and then through the setting of two heat-resistant pressure plates, squeeze and position the edge of the knife back and blade to be welded, and cooperate with the flat warp limit layer in the welding gap of the knife. When the knife back is inserted into the U-shaped When the extrusion force is generated in the flat and warped limiting layer, the internal gap-filling particles are squeezed into the warped gap, that is, to fill the space of the warped part, so that the softness and rigidity of the warped part of the knife back are changed. The positioning makes the knife back in a stable state as a whole, and it is not easy to shake during welding, thereby effectively improving the linear integrity of the weld and improving the welding effect
