Method for making shoe upper template according to shoe tree type and shoe upper face forming technology

Abstract

The invention discloses a method for making a shoe upper template according to the shoe tree type and a shoe upper face forming technology. The method for making the shoe upper template according to the shoe tree type comprises the steps of uncovering semi-face textured paper cut on a shoe tree and unfolding the textured paper on a card paperboard; taking the part which accounts for 1 / 3 of the total length of a tree face from the foremost end to obtain a point A and a point B at the back middle line and the upper foot edge line, and conducting rotary and warping reducing processing on the front end part of the line AB with the middle point of the front end part of the line AB as the circle center; taking the part which accounts for 1 / 3 of the total length of the tree face from the rearmostend to obtain a point D on the upper foot edge line, taking the part which accounts for 3 / 5 of the total length of the tree face from the foremost end of the tree face to obtain a point E of the backmiddle line, and taking a point F at the front end of the point E from the back middle line; with the point D as the circle center, rotating the rear end part of the line DE upwards to the point E tofall onto the line DF; cutting DEF to make the shoe upper cutting piece template. The method for making the shoe upper template is simple, the shoe upper face shoe head can completely fit the shoe upper without reservation of remaining leather, the cost in the shoe upper face forming technology is lowered, and the production benefit is increased.

Description

technical field [0001] The invention relates to the technical field of footwear product manufacturing, in particular to a method for manufacturing a shoe upper template according to a shoe last shape and a shoe upper surface forming process. Background technique [0002] The development of my country's shoemaking technology has experienced a long historical process from simple to complex, from rough to refined, from manual production to machine production; it has made great contributions to the advancement of human society. From the traditional sewing process, to the modern gluing, vulcanization, molding, injection molding and shoemaking processes have undergone tremendous and profound changes. The advancement of technology is the product of socialized industrial production, and it is a powerful guarantee for product quality and production efficiency. Only by constantly innovating technology can we quickly organize production according to market demand, and achieve higher pr...

[0003] At present, the molding of the finished shoes with one-piece toe cap on the market is made by the semi-hanging upper process. Specifically, the midsole cloth and the upper surface are sewed by the upper locomotive first, and then the shoe last is completed by the hand-held handle. , and then pull the toe part to spray glue on the nozzle of the glue spraying machine. Among them, there is about 10mm of leftover skin on the toe of the upper surface. Therefore, it is necessary to brush white latex on the leftover skin, and apply glue After that, put the lasted shoe upper into an oven to dry the glue on the remaining leather of the toe, and then set the correct parameters for the use of the upper machine so that the discharge of the front paws of the upper machine matches the radian of the last. And pull down the remaining leather to make the upper surface and the shoe tree completely fit, and then complete the forming process of the upper surface through the process of the upper machine and the process of tying the shoelaces; in this production process, the required personnel input Big, in the gluing process of the leftover skin of the toe, one person needs to spray glue at the glue sprayer, one person uses a brush to apply white glue to the leftover skin of the upper and the midsole, and two people use the front upper machine to make the upper surface Tensioned on the shoe last, the labor cost is high, the process is complicated, the production capacity is low, and the production efficiency cannot be effectively improved. In addition, the upper surface of the shoe may be broken after being dried in the oven and pulled by the front upper machine. Problems such as shoe hair corners affect the quality of the product
