Description

1377297 VI. Description of the Invention: [Technical Field] The present invention relates to a method of riveting a fastener, and more particularly to a method of riveting a fastener for increasing the strength of the side riveting. [Prior Art] The riveting of the conventional fasteners is mainly based on various punching machines, presses or folding machines, and the other molds or jigs designed according to the fasteners and the target workpieces are processed. It can be properly riveted and has an absolute relationship with the material properties of the target and the riveting position of the fastener on it. Therefore, the specifications of each type of fasteners set the shortest distance requirement for the edge of the fastener from the centerline to the standard 10 position. Below this requirement, there is no guarantee that the fasteners will be properly riveted. Furthermore, if the design of the part cannot match the shortest distance requirement (the center line of the fastener to the edge of the target position), the tightening is often enhanced by secondary processing. For example: traditional argon welding, spot welding, filler welding, laser welding, strong adhesive or other means. Therefore, with the above-mentioned conventional methods, the following defects exist: 1. The riveting position of the fastener has a large limitation. 2. The yield is low. Even if the trimmings meet the specifications, the riveting failure may be caused by the relationship between the hardness and hardness of the material. 3. Even if the target workpiece is designed to fit the specifications of the fastener completely, there are % which will inevitably result in defective products that cannot be tightened because some dimensions or specifications are just at the edge of the tolerance or the tolerance is accumulated. 4, the cost is significantly higher, for example: (1) because there is a risk of not being able to tighten the riveting 'so the riveting often requires immediate verification, thus reducing productivity and efficiency (high unit processing costs); (2) by strange To the proficient learning curve is longer, the cost of education and training is higher; (3) the subject matter may be because the edge material is not 4/20 1377297

It is necessary to increase the volume, thereby increasing the cost of materials and molds, processing and transportation; (4) increasing the selection and inspection costs because sufficient yield cannot be guaranteed; and (5) the cost of heavy work and scrapping after the selection of defective products. ▲"The reason is that the inventor has felt that the above-mentioned deficiency can be improved, and based on years of experience in this field, carefully observed and studied, and with the use of academics, a reasonable design and effective improvement of the above Missing = [invention content]

The technical problem to be solved by the present invention is to provide a fastener riveting method which is turned over to the side riveting strength. The invention can not only pass through the structure, but also make the riveting body not extend outward in the direction of the pre-(four) side, and can also force the target object and the Ps workpiece to be forced. Into the surrounding groove of the firmware, thereby strengthening the riveting strength between the workpiece and the fastener. σ

In order to solve the above technical problem, according to one aspect of the present invention, a fastener riveting method for increasing side riveting strength is provided, which comprises the following steps: first, providing - mold structure, - fastener and riveting workpiece The mold structure has an upper mold and a lower mold, the fastening: having a head portion and an extension extending downward from the head portion, and the Liuhe workpiece has a riveting body and a penetration The through hole of the riveting body is spliced, 'the extension of the pure piece is passed through the through hole of the workpiece, and the head of the fastener is located on the upper surface of the riveting body, wherein the firmware is adjacent to the Riveting the predetermined side of the body; then, placing the riveted workpiece on the lower mold so that the bottom end of the extension of the fastener is placed in the reading, and the 1F is used to 'transmit through the structure The head 5/20 of the fastener is pressed against the upper side of the riveting body so that the head of the fastener is embedded in the riveting body, through which the stop is "The structure 1 depends on the predetermined side of the riveted body so that the riveted body does not The direction of the predetermined side is outwardly extended; finally, the blocking structure and the upper mold are removed to take out the riveted workpiece into which the fastener is embedded. In order to solve the above technical problem, according to one aspect of the present invention, A fastener riveting method for increasing side riveting strength is provided, comprising the steps of: firstly providing a die structure, a fastener and a riveting workpiece, wherein the die structure has an upper die, a lower die and a Having a punch-down mold release plate, the lower mold release plate is disposed between the lower die and the riveted workpiece, and has a head portion and an extension portion extending downward from the head portion Having a surrounding groove adjacent to the head, and the riveted workpiece has a riveting body and a through hole penetrating the riveting body; and then extending the extension of the fastener through the riveted workpiece a through hole so that the head of the fastener is located on the upper surface of the staking body, wherein the fastener is adjacent to a predetermined side of the staking body,
