Problems solved by technology

[0003] At this time, since the bottom surface of the foam is supported as a whole, under the same support force, if the support force of the frame is guaranteed, the waste discharge of the inner frame will require a greater force, which will easily cause the foam to tear and leave residue on the inner frame
If it is to ensure that the waste of the inner frame is easy to discharge, it is easy to drive the frame, causing displacement and deformation
[0004] At the same time, in the case of strong supporting force, most of them use manual waste discharge, which is very inefficient
In the case of weak supporting force, equipment waste can be discharged, but the probability of frame displacement and deformation is high

Abstract

The invention discloses a foam component and a processing method thereof. The processing method includes the steps of: S1: sticking a monolayer protective film to the upper surface of a first protective film; S2: punching an area with a set shape on a release film by a punching technology; S3: removing a first release film located outside the area, and sticking the upper surface of the foam on the first protective film in the area and beyond the area; S4: punching the foam and the first protective film through by a punching technology to form an annular part on the foam, with the inner edge of the foam's annular part located outside the outer edge of the first release film; and S5: removing the water material outside the annular part. The processing method for the foam component provided by the invention facilitates the punching processing of foam and reduces the shift deformation risk of the foam frame.

Description

technical field [0001] The invention relates to the field of precision die cutting, in particular to a foam component and a processing method thereof. Background technique [0002] In the die-cutting production process, foam is a common material used, but due to the characteristics of the foam itself, the frame of the back-shaped foam is relatively narrow, and it is more difficult to process. Because the foam is easy to deform, it will be displaced and deformed by the extrusion of the die during punching. At this time, it is necessary to add a layer of material on the bottom of the foam to support the foam frame. [0003] At this time, because the bottom surface of the foam is supported as a whole, under the same support force, if the support force of the frame is guaranteed, the waste discharge of the inner frame will require a greater force, which will easily cause the foam to tear and leave residues in the inner frame . If it is to ensure that the inner frame waste is e...
