Method for producing fast clamp by using magnetic lines to fix objects attracted by magnetic force

Abstract

The present invention is a method for making fast jigs by using magnetic lines of force to fix objects to be magnetically attracted, which includes: A. Confining magnetic powder particles in a space; B. Shaping the surface of magnetic powder particles into the contact surface of the jig Shape; C. Apply an effective magnetic force to the back of the magnetic powder particles outside the space, so that the magnetic powder particles form a compact fixture in the above space through the action of magnetic force lines; D. By stopping the magnetic force, Restore the magnetic powder in the space and wait to be shaped again; thereby forming a jig that can be quickly shaped and restored.

Description

technical field [0001] The invention relates to a method for making a jig. Background technique [0002] Press, currently in the process of shoemaking, in order to make the sole and the upper stick together, after gluing between the upper and the sole, there is usually a bottom mold matching the shape and pattern of the sole on the top of the shoe, and the upper is pressed There are pressure bars, and the upper and the sole are tightly bonded by applying external force. However, since the shape of each type of sole is different, and the same style of shoes has different models and sizes, it is necessary to specially make a special sole corresponding to the shape of the model for each type of shoes. Therefore, the cost of manufacturing the bottom mold is quite large, and each time a different shoe sole is bonded, the matching bottom mold needs to be replaced, so it is also necessary in the bonding process. Quite inconvenient. [0003] In order to improve the shortcomings o...

However, since the shape of each type of sole is different, and the same style of shoes has different models and sizes, it is necessary to specially make a special sole corresponding to the shape of the model for each type of shoes. Therefore, the cost of manufacturing the bottom mold is quite large, and each time a different shoe sole is bonded, the matching bottom mold needs to be replaced, so it is also necessary in the bonding process. quite inconvenient

[0003] In order to improve the shortcomings of the known shoe-making moulds, there is a patent case for the structure of the base plate base plate of the shoe-making machine as Taiwan New Announcement No. 424433, which lays a laminated cushion on the base mold, and presses the inside of the cushion. There are movable rods driven by a plurality of pressure cylinders, and these movable rods can be pressed against the sole for bonding. However, in such a structure, since there is still a gap between each movable rod, it will A dead angle is formed, causing the sole to be bonded incompletely and become loose. It also cannot be used with soles of different shapes and patterns.

[0004] In addition, there is a patent case for the No. 567760 sole pressing machine of Taiwan New Bulletin, which is a pressing pad of a high-foaming cotton body with a hardness on the bottom mold, and a certain number and size of pads are filled below the pressing pad. Steel balls, so that the steel balls can be filled in the gaps of the soles when they are pressed, so that they can be fixed and conform to the shape and pattern of the soles. However, because there are still dead angles between each steel ball, and in the process of filling, the steel balls will still Rolling, resulting in inaccurate filling, and unable to completely make the sole and upper tightly bonded, so it is not ideal for use
