Problems solved by technology

[0003] Traditional laser tailor welding equipment for unequal thick plates mostly uses a hydraulic cylinder to drive a compression mechanism to press the welding plate for welding. This structure is complex, resulting in a very narrow space above the plate to be welded, which easily affects the activities of the welding head. ; and it is difficult to adjust the pressing jaws at the bottom of the pressing mechanism to a horizontal plane, which will lead to uneven force at each point when the plate is pressed and affect the welding effect
The pressure claws of the traditional pressing mechanism are also very easy to cause scratches on the board surface and affect the customer's use

Embodiment Construction

[0038] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0039] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no interveni...

Abstract

The invention discloses tailored blank laser welding equipment. A pressing mechanism of traditional tailored blank laser welding equipment is replaced through an electromagnetic platform; the structure is simple; a space above a plate to be welded is wide without influencing the movement of a welding head; downward pressure of the pressing mechanism of the traditional tailored blank laser welding equipment is replaced by sucking force generated by an electromagnet to achieve the purpose of plate fixation; the stress generated in the welding can be overcome to prevent a welding line from cracking; an indentation on the surface of the plate caused by the use of the pressing mechanism also can be prevented; and the condition of influence on the welding effect due to uneven stress is not generated. The invention further discloses a tailored blank laser welding method.

Description

technical field [0001] The invention relates to tailor welding equipment, in particular to a laser tailor welding equipment and a laser tailor welding method. Background technique [0002] Now laser tailor welding has been widely used in high-end cars in the automobile market, and it is the most advanced car body manufacturing technology in the world. By laser welding steel plates with different thicknesses, different coatings and different materials and then stamping them, it can not only give full play to the performance of raw materials, reduce the weight of the car, increase the impact and anti-collision performance of the car, but also reduce the car by 10%-15%. production cost. In the future, with the decline of technical threshold and production cost, it will be gradually applied to middle and low-end cars, and it will have a very broad market prospect. Tailored laser welding enterprises in the domestic market are mainly in the form of sole proprietorship and Sino-f...
