Embodiment 1

[0039] see figure 1 , the present invention provides a technical solution: a method for a customized leather shoe last structure,

[0040] The main structural curve of the private custom leather shoe last is formed, and the specific steps are as follows:

[0041] Step 1: Establish rectangular coordinates;

[0042] Step 2: Determine the coordinate positions of the 5 control points on the sill line after the last;

[0043] a. Determine the point O, which is the height of the back sill of the last, and the design height is 90mm;

[0044] b. Determine the coordinate positions of W point, R point, P point and E point;

[0045]Point W is the intersection point of the back-swing line and the bottom horizontal line; and the length of the back-swing line OW line segment is the key to determine the position of W point; the size is obtained according to the law: the length of the back-swing line OW is equal to the length of OW on the bottom sample plus The forward movement of the lan...

Abstract

The invention discloses a method for customizing the structure of a leather shoe last, which includes establishing rectangular coordinates; determining the coordinate positions of five control points on the last sill line; determining the position of the front point B; determining the back arc curve of the plain head last and the bottom curve of the last On the coordinate diagram of the shoe last structure design, the center line of the bottom of the last and the center line of the back arc of the last are two complementary structural control lines; master the changing law of the interaction of several control points on these two lines, and then combine the human body With the optimization of engineering design, it is possible to conveniently design a last shape that is beautiful in shape and meets the needs of specific customization; this method has the characteristics of flexible application, simple operation, and strong reliability, and is worth promoting. This method can be further improved and perfected The level of shoe-making technology further meets the individualized consumption needs of the people.

Description

technical field [0001] The invention relates to the field of smallpox buckle leather shoes, in particular to a method for customizing a leather shoe last structure. Background technique [0002] In the production process of leather shoes, shoe last is an indispensable shaping mold, which determines the comfort and aesthetics of leather shoes. The shoe last used by the shoe factory is designed by the designer first with a standard sample last, and then the whole set of shoe lasts with different shoe sizes are engraved by the last engraving machine. The size of the standard last is based on the national standard size, and it is difficult to obtain the extra large and extra small special size lasts required by private customization, and it cannot meet the differentiated needs of special foot shapes. This forces us to explore new ways to solve it. Contents of the invention [0003] The purpose of the present invention is to provide a method for customizing the leather shoe l...
