Description

Technical Field

[0001] The utility model belongs to the technical field of shoe lasts, and in particular relates to a shoe last rough processing device. Background Art

[0002] The shoe last is both the mother body of the shoe and the molding mold of the shoe. The shoe last not only determines the shape and style of the shoe, but also determines whether it fits the foot and whether it can protect the foot.

[0003] At present, the rough processing equipment for shoe lasts on the market is relatively backward, and because the surface of shoe lasts is mostly curved, the angle of the rotation mechanism of the rough processing equipment for shoe lasts needs to be adjusted during the processing. The B-axis rotation of the shoe last processing equipment on the market is all driven by a servo motor with a lead screw, which drives the connecting rod and then swings the angle. However, this structure is prone to inaccurate B-axis rotation angles due to deviations in the workpiece and matching deviations. In order to solve this problem, our company directly uses a servo motor to directly drive the rotation angle with a reducer, simplifies the mechanism, and improves the accuracy of the swing angle.
