Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] see Figure 1-2 , a pressure-resistant special stamping protective film, including a surface layer 1, the outer surface of the surface layer 1 is wrapped with a protective layer 2, through the use of the protective layer 2, the adhesive block 3 and the support strip 4, the surface layer 1 can be increased. For the coverage of materials, it can reduce the stress area of ​​materials under pressure during special stamping work, effectively increase the pro...

Abstract

The invention relates to the technical field of protective films and discloses a pressure-resisting specific stamping protective film. The pressure-resisting specific stamping protective film comprises a surface layer, wherein a protective layer covers the outer surface of the surface layer; two sides of the top of the protective layer are fixedly connected with bonding blocks; one side of one bonding block is fixedly connected with the other bonding block through a supporting strip; an upper hardening layer is arranged at the top of an inner cavity of the surface layer; the bottom of the upper hardening layer is fixedly connected with a lower hardening layer; the bottom of the lower hardening layer is fixedly connected with a protective film layer; the bottom of the protective film is fixedly connected with an upper bonding layer; the bottom of the upper bonding layer is fixedly connected with a base film; the bottom of the base film is fixedly connected with a lower upper bonding layer; the bottom of the lower upper bonding layer is fixedly connected with a bearing film. According to the pressure-resisting specific stamping protective film, the protective layer, the bonding blocks and the supporting strip are matched so that a coverage range of the surface layer on a material can be enlarged; the stress area of pressure on the material can be reduced when specific stamping work is carried out and the protection effect on the material is effectively increased.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a special pressure-resistant stamping protective film. Background technique [0002] Special stamping processing is a production technology that uses the power of conventional or special stamping equipment to directly deform the sheet metal in the mold to obtain product parts of a certain shape, size and performance. Sheet metal, molds and equipment are The three elements of stamping processing are divided into hot stamping and cold stamping according to the stamping processing temperature. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity, while the latter is carried out at room temperature. It is a commonly used stamping method for thin plates. It is a metal One of the main methods of plastic processing (or pressure processing), also belongs to material forming engineering technology. [0003] At present, protective...
