Embodiment Construction
[0030] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0031] see figure 1 , a production method of laser tailor-welded steel plates with unequal material thickness, said method is operated according to the following steps:
[0032] First utilize thin steel plate 4 to produce thin steel blanking piece 1, utilize thick steel plate 5 to produce thick steel blanking piece 2, then described thin steel blanking piece 1 is placed on the left or right side, described thick steel blanking The sheet 2 is placed on the right or the left. Specifically, in this embodiment, the thin steel blanking sheet 1 is placed on the left, the thick steel blanking sheet 2 is placed on the right, and the thin steel blanking sheet 2 is placed on the right. 1 and the blanking piece 2 of the thick steel plate are ta...

The invention discloses a method for producing laser welding tailored blanks with different thicknesses and belongs to the field of automobile cold stamping dies. The method comprises the following steps: respectively developing a set of uncoiling and blanking die for the laser welding tailored blanks with the different thicknesses required by a stamping process according to the shapes of thin and thick steel plates before tailor welding by taking the tailor welding line as a parting line, and respectively producing thin steel plate blanking pieces and thick steel plate blanking pieces; and arranging the thin steel plate blanking pieces on the left side or the right side, arranging the thick steel plate blanking pieces on the right side or the left side, and welding the thin steel plate blanking pieces and the thick steel plate blanking pieces according to the thick difference direction required by the stamping process. By adoption of the production method, the investment of die tool cost is reduced, and the production process is reduced, so that the automatic blanking production is realized, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the field of automobile cold stamping dies, in particular to a production method of laser tailor-welded steel plates with unequal material thickness. Background technique [0002] The laser tailor welded steel plate with different material thickness is an integral steel plate formed by automatically joining and welding several steel plates of different materials, different thicknesses and different coatings by using laser energy. At present, laser tailor-welded steel sheets with different thicknesses are widely used in the automotive industry due to their light weight and good structure. [0003] At present, the tailor-welded steel plates with different material thickness provided by laser tailor-welded manufacturers are square tailor-welded steel plates. For large stamping parts with complex shapes such as integral door inner panels, it is difficult for square tailor-welded steel plates to meet the stamping process requiremen...
