Description

High-adaptability toe cap hot-cold setting machine and setting method Technical Field The invention relates to the technical field of toe cap shaping, in particular to a high-adaptability toe cap hot-cold shaping machine and a shaping method. Background In the field of footwear manufacturing, heat and cold setting of the toe cap is a critical process for shaping the appearance of the article of footwear and maintaining the set. The existing toe cap hot-cold setting machine commonly adopts a mode that a pressing piece and a shoe lining are matched with each other to realize setting operation. The working principle is that the heated and softened toe cap is placed on the shoe lining, then the driving mechanism controls the pressing piece to press downwards, so that the toe cap material is tightly attached to the outer contour of the shoe lining, and the required three-dimensional shape is obtained after pressure keeping and cooling. However, to ensure a sufficient fit between the toe cap and the sock liner, the press-fit must continue to act on the toe cap surface with a high force, which results in significant friction at the contact interface between the two. Particularly, the pressing piece in the prior equipment usually adopts a simple straight up-down motion track. In this mode, in a single shaping cycle, the pressing member will generate sliding friction with the toe cap surface in both the pressing-down lamination and the rising-up resetting stages. The side friction generally does not cause visible damage to the toe cap itself, but it continues and builds up on the wear caused by the inside of the press fit. With the increase of production batches, the abrasion loss of key working faces of the pressing piece is multiplied, so that the thickness of the inner side of the pressing piece is gradually reduced, the shape accuracy is reduced, the service life of the pressing piece is reduced, and the consistency of subsequent toe cap shaping and the quality of a final finished product are influenced due to the gradual misalignment of shaping dies.
