Problems solved by technology

The disadvantage of this method is: the force on the surface of the leather shoes to be plastic is static, if the surface of the leather shoes is soft and hard, and there are large errors in the physical and chemical performance indicators and thickness of the material, the plastic surgery effect is not ideal

Embodiment 1

[0017] A shoe-shaped composite extrusion ironing shaping method, comprising the following steps:

[0018] (1) Fix the shaping mold on the workbench of the shoe shaping machine, and adjust the temperature of the shaping mold to 90°C;

[0019] (2) Put the leather shoes to be shaped into the shaping mold;

[0020] (3) The thrust of the cylinder acts on the part to be shaped through the shaping mold at the same time;

[0021] (4) After a certain period of time, the cylinder is automatically reset;

[0022] Among them, the cylinder thrust in step (3) includes the force exerted by the cylinder pulse.

[0023] In step (3), mode 1 can be selected: the cylinder extrusion force maintains an atmospheric pressure of 0.2 MPa to 0.6 MPa, and the holding time is 8 s to 12 s.

[0024] In step (3), mode 2 can be selected: the cylinder pulse frequency is set to 1HZ~20HZ, and the time is set to 8s~10s.

[0025] Step (3), you can choose mode three: the cylinder extrusion force maintains the a...

Embodiment 2

[0030] A shoe-shaped composite extrusion ironing shaping method, comprising the following steps:

[0031] (1) Fix the shaping mold on the workbench of the shoe shaping machine, and adjust the temperature of the shaping mold to 90°C;

[0032] (2) Put the leather shoes to be shaped into the shaping mold;

[0033] (3) The cylinder extrusion force maintains an atmospheric pressure of 0.2 MPa, and the holding time is 8 s;

[0034] (4) Automatically reset the cylinder after maintaining the pressure for 8s.

[0035] In this embodiment, shoes whose main heel and back of the head are made of relatively hard materials and whose inner lining is made of hot-melt materials are preferred, such as combat boots, safety shoes, and the like.

Embodiment 3

[0037] In this embodiment, the extrusion force of the cylinder is maintained at 0.2 MPa, and the holding time is 9 s, and the other steps are the same as in Embodiment 2.

Abstract

The invention discloses a composite extruding, ironing and shaping method of shoes. The composite extruding, ironing and shaping method comprises the following steps: (1) fixing a shaping mould on a workbench of a shoe shaping machine, regulating the temperature of the shaping mould; (2) placing to-be-shaped leather shoes into the shaping mould; (3) simultaneously applying gas cylinder thrust on a to-be-shaped part by virtue of the shaping mould; and (4) after keeping for a certain time, automatically resetting the gas cylinder, wherein the gas cylinder thrust in the step (3) includes force applied by gas cylinder pulses. According to the technical scheme adopted by the invention, the composite extruding, ironing and shaping method of the shoes has the advantages that different modes can be selected according to the softness of the surfaces of the to-be-shaped shoes, the physical and chemical performance indexes of materials and the difference of thickness, so that not only can the vibration function be realized, but also the static pressure-retaining function can be realized, and therefore, the shoes made from different materials can obtain satisfied shaping effects.

Description

technical field [0001] The invention relates to a shoe shape shaping method, in particular to a shoe shape compound extrusion ironing shaping method. Background technique [0002] Using molds to reshape the appearance of leather shoes is an advanced method of reshaping leather shoes, which can significantly improve the appearance quality of leather shoes and make the appearance of leather shoes more smooth and beautiful. The method is: fix the shaping mold on the workbench of the shoe shape shaping machine, heat the shaping mold to a suitable temperature, put the leather shoes to be shaped, start the shaping machine to make the upper and lower cylinders of the shaping machine move simultaneously, and the thrust of the cylinder acts simultaneously through the mold and waits. For the reshaping part, after a certain period of time, the cylinder is automatically reset, and the reshaped leather shoes are taken out. The disadvantage of this method is: the stress on the surface of...
