Description

Angle-adjustable mechanism for non-deformable leather and synthetic material

Technical Field

The present invention relates generally to the field of shoe upper cutting machines, and more particularly to a mechanism for adjustable angles of non-deformable leather and synthetic materials, in relation to leather and synthetic materials crimping and sizing.

Background

The known technology of the hemming and sizing mechanisms is to shape the upper by combining two different methods, namely purposeful cutting and geometric calculation according to the design of the shoe, so that a piece of leather material is formed into a shape with a steep angle for placing and further processing (sewing, gluing, etc.) on the toe and the body of the shoe.

In the general description of the prior art according to fig. 1, the oldest system consists of two metal plates 11 which are used to grip the leather material and then stretch the gripped leather material into the desired shape through an adjustable opening.

According to the prior art shown in figure 2, the newer system has a flexible male mould 13 of various shapes and sizes, on which a piece of leather material is placed and then pressed against a mould 14, which makes the leather material take a shape with a curved angle.

Both of the above prior art techniques suffer from various problems. The prior art shown in fig. 1 would plastically deform the leather due to the characteristics of the process, thereby generating wrinkles during the process and irregularly deforming the leather material. Therefore, after setting, trimming is usually carried out on a trimming jig, which results in waste of time and material, and the surface of the material is damaged due to the trimming, so that the composite material cannot be processed in this way. In addition, another problem is that since the shape of the metal plate is fixed, only a fixed angle can be used, and if the angle needs to be adjusted, the metal plate needs to be replaced, which takes a lot of time and cost.

The prior art shown in figure 2, although capable of producing formed parts without wrinkles, covers very limited angles and applies uneven forces, resulting in the center of the material being subjected to most of the pressure and less as it extends to the edges of the material. Since excessive stretching of the elastic mold may cause deformation, the pressure on the material is not uniform based on the process, so that increasing the final angle by the pressure may cause the material to stretch and start forming wrinkles. This prior art is also suitable for synthetic materials, since it operates on the principle of a male-female mould, rather than on the principle of drawing, and although it is possible to vary the angle of the formed part by adjusting the pressure, the angles that can be achieved are far from satisfying the requirements of daily production, it only deals with simple geometries, and it does not fulfill the requirements of dealing with steep angles.

Disclosure of Invention

The object of the present invention is to overcome and eliminate all the problems and drawbacks of the prior art mentioned above. By providing a new way for setting leather and synthetic materials, it is possible to set the respective materials at a desired angle without irregular deformations. The angle of the shaping can be adjusted, so that the shaping device can be used with any kind of materials. This process will apply uniform pressure to the entire mass of material and eliminate the need for subsequent trimming or ironing.

The angle-adjustable mechanism for the non-deformable leather and the synthetic material comprises an angle-adjustable mechanism main body, a supporting seat and a convex mold, wherein the supporting seat comprises a first cylinder and a second cylinder, and the bottom of the convex mold is provided with two slidable supporting plates; the supporting plate is provided with a through hole, the through hole is provided with a base connecting shaft, and two sliding blocks are arranged above the supporting plate; the supporting plate is provided with a cylinder connecting shaft connected with a third cylinder; the convex mold is combined with the concave mold and locked in place; different angles are adjusted through a third cylinder and a sliding block of the convex surface die, the convex surface die is pressed on the concave surface die, the shape of the concave surface die is reproduced through the concave-convex combination principle, the uniform compression resistance of the whole area is realized, and the tensile deformation of the convex surface die is controlled.

Further, the third air cylinders are movable, and the convex surface mold can be adjusted to different angles under the interaction of the two third air cylinders.

Further, the first cylinder and the third cylinder drive the support plate to move, the base connecting shaft fixes the sliding block on the support plate, and the sliding block fixes the elastic convex die at a proper position and controls the stretching condition of the elastic convex die at the same time.

Further, the material is placed on the convex mold, the first air cylinder and the second air cylinder are sequentially started, the convex mold is bent to a certain angle through the interaction of the two third air cylinders, the material is shaped into a desired shape under the interaction of the convex mold and the concave mold, and uniform pressure is applied to the whole processed material.

The mechanism can directly shape any material into different angles without irregular deformation, does not need subsequent finishing or ironing processes, and can realize angle adjustment without replacing a die. In addition, it ensures that the entire portion of the material is subjected to uniform pressure, and the elastic convex mold is modified to be hardly stretched or displaced, ensuring that the material is not wrinkled.
