Loose core sheet riveting device

Abstract

The invention discloses a loose core sheet riveting device. The loose core sheet riveting device comprises a supporting assembly, a riveting assembly and a riveting driving assembly; the supporting assembly is provided with a sheet positioning site for positioning the loose core sheet; the sheet positioning site is provided with a reference direction; the reference direction is the axial directionof a to-be-riveted opening of the loose core sheet after the loose core sheet is positioned on the sheet positioning site; the riveting assembly is provided with a riveting block which is driven by the riveting driving assembly to move back and forth relative to the sheet positioning site and along the reference direction; and the riveting part of the riveting block is a trapezoidal riveting groove with a wide opening and a narrow bottom. In the riveting process, the two riveting parts are close to each other and can adaptively adjust to maintain the own shape, so that the extruded deformation can be avoided when the riveting parts are close to each other to be riveted; a hole formed after riveting adopts a round structure, the product has good appearance, the activity freedom degree of the loose core sheet and a Japanese circle is good, and the user experience feeling is excellent. The loose core sheets with any different sizes can be riveted through adjustment; and the product can automatically separate from the riveting device after product riveting and assembling are completed, so the loose core sheet riveting device is very flexible, simple, convenient and efficient.

Description

technical field [0001] The invention relates to the technical field of riveting, in particular to a riveting device for pulling out chips. Background technique [0002] In recent years, with the growth of customers' personalized needs, the zipper puller is no longer simply hanging the pull tab, but adopts the combination configuration of the Japanese ring and the pull chip. The Japanese ring is hung on the zipper head, and the pull chip is riveted. Close on the Japanese circle. Many types and styles of pumping chips are customized according to customer requirements. Among them, in the operation of assembling and extracting chips, most of the surviving enterprises still use manual supplementary simple jigs to complete the operation. The operation efficiency is low, the labor intensity of the employees is high, and the appearance of the riveted products is not good. In the prior art, there is an assembly machine (CN201710170401.5) with a Japanese-style ring slider that autom...

Problems solved by technology

[0003] In short, in the prior art, regarding the riveting operation of chip extraction, no matter it is manually assisted or automated, the force action mode adopted for riveting is closed riveting and riveting pressure. After this form of riveting, if Figure 10 As shown, the two riveting parts of the chip are easily deformed (elongated) by external force, and the holes formed by the semicircular riveting parts are extruded into oval structures after riveting, which greatly affects the appearance of the product, and also Affects the degree of freedom of drawing chips relative to the activities of the Japanese circle, and affects the user experience
