Problems solved by technology

[0003] Materials of different materials are tailor-welded by laser, and then stamped to obtain the required parts, which can reduce the number of parts in the overall mechanism and achieve the purpose of improving performance. However, when plates of different materials are welded by laser, the two plates There is always a certain gap in the molten state of the splice, so that the strength of the weld is reduced or even cracked. In addition, the welded blank has a large residual stress at the weld because of the different plates used. , if it is not treated in time, it may cause weld cracking during the stamping process resulting in defective products

Abstract

The invention discloses a rotating disc type laser welding plate forming machine which comprises a rack, a rotating disc mechanism, a laser welding mechanism, a material taking mechanism, a jig, a welding extrusion mechanism, a rolling mechanism, a cover plate re-locking mechanism and a discharging hopper, and is characterized in that the center position of the upper end face of the rack is connected with the rotating disc mechanism through a bolt; a cover plate re-locking mechanism, a welding extrusion mechanism and a rolling mechanism are sequentially arranged on the upper end face of the rotary disc mechanism around the rotary disc mechanism, and jigs are fixedly installed on the periphery of the rotary disc mechanism and correspond to a manual feeding station, a cover plate re-locking station, a welding station and a material taking station correspondingly. The clamping mechanism in the jig is pushed by the downward pressure of the welding extrusion mechanism, so that the two plates receive certain extrusion force in the welding process, and the occurrence of welding seam cracking caused by a gap generated in the welding process is reduced.

Description

technical field [0001] The invention relates to the technical field of laser tailor welding equipment, in particular to a turntable laser welding plate forming machine. Background technique [0002] Tailored laser welding is to use laser energy to assemble and weld several sheets of different materials to form a whole sheet to meet the different requirements of parts for material properties, and achieve light equipment with the lightest weight, optimal structure and best performance. Quantification is widely used in the automotive field; [0003] Materials of different materials are laser welded, and then stamped and formed to obtain the required parts, which can reduce the number of parts in the overall mechanism and achieve the purpose of improving performance. However, when laser welding of different materials is performed, the two plates There is always a certain gap in the molten state of the splicing, so that the strength of the weld is reduced or even cracks occur. I...
