Description

Technical Field

[0001] The utility model relates to the technical field of dust cover production, in particular to a dust cover stamping device. Background Art

[0002] The most critical link of the dust cover in stamping production is the stretching process. Due to the relatively high stretching height, the stamping material is easily damaged, broken and scratched during the stretching and extrusion process. In order to avoid this situation, protecting the stamping material from damage and reducing friction during the stretching process becomes a very important process flow. A layer of plastic film is artificially covered on the upper surface of the stamping material, and lubricating oil is applied to the lower surface of the stamping material, which avoids damage to the stamping material surface and reduces friction during the stretching process.
