A method for manufacturing a shoe last bottom curve clamping plate

Abstract

The invention discloses a method for manufacturing a shoe tree bottom curve clamping plate. The method comprises the following steps: S1, drawing a shoe tree bottom sample, wherein part points and edge points corresponding to the part points are arranged on the shoe tree bottom sample; S2, drawing shoe tree tiptoeing flat lines; S3, drawing a shoe tree bottom curve; S3(1), drawing a third vertical line which is vertical to a rear tiptoeing flat line and has the fixed length by an intersection point of a first vertical line and the rear tiptoeing flat line, and drawing a heel arc line by using one end point of the third vertical line as a start point and using the other end point of the third vertical line as an end point; S3(2), determining a heel center part point, a concave point and a toe end point on the clamping plate according to the part points and the edge points on the shoe tree bottom sample, and connecting a high heel point, the heel center part point, the concave point, a forefoot strength point, the toe end point and a high forefoot point on the clamping plate to form the bottom curve. The method has the beneficial effects that the curve clamping plate which is manufactured on the basis of the part points of a foot of a human body is relatively high in bottom concavity and is perfectly matched with a sole curve of the human body; produced shoes are higher in comfort.

Description

【Technical field】 [0001] The invention relates to the technical field of shoe last manufacture, in particular to a method for manufacturing a shoe last cross-section clip. 【Background technique】 [0002] The shoe last is the mother body of the shoe and the forming mold of the shoe. The shoe last not only determines the shape and style of the shoe, but also determines whether the shoe fits and protects the foot. Therefore, the design of the shoe last must be based on the shape of the foot. The bottom curve of the shoe last is the most important factor that determines the comfort of the shoe. In the process of shoe last production, the bottom curve of the shoe last can be designed first, and then the shoe last that matches the curve of the human foot can be made according to the bottom curve of the card. However, it is found through investigation that most of the shoes made according to the existing shoe tree are still not easy to wear, and their comfort is relatively poor, es...

[0002] The shoe last is the mother body of the shoe and the forming mold of the shoe. The shoe last not only determines the shape and style of the shoe, but also determines whether the shoe fits and protects the foot. Therefore, the design of the shoe last must be based on the shape of the foot. The bottom curve of the shoe last is the most important factor that determines the comfort of the shoe. In the process of shoe last production, the bottom curve of the shoe last can be designed first, and then the shoe last that conforms to the curve of the human foot can be made according to the bottom curve of the card. However, it is found through investigation that most of the shoes made according to the existing shoe tree are still not easy to wear, and their comfort is relatively poor, especially high-heeled shoes. When walking with shoes, most people find it unnatural to walk, and they say that walking is very tiring. When you use the insole to cut a small piece and put it on the waist of the shoe, the problem is solved, and it is much more comfortable to wear. From this we can see that, Most of the shoes in the market have insufficient concavity at the bottom of the waist, and the curve design does not fit well with the soles of the human body. The shoes do not follow the feet, walking unnaturally for fear of falling. Wearing such shoes for a long time will easily lead to flat arches. In severe cases, surgery may be required.

Therefore, the existing shoe lasts still have certain defects, and it is urgent to provide a method for manufacturing the curved clamping plate at the bottom of the shoe last. The curved clamping plate produced according to this method can produce shoes with higher comfort and meet people’s needs.
