Description

Technical Field

[0001] The utility model relates to the technical field of indentation, and specifically discloses an indentation bottom plate with through indentation. Background Art

[0002] The indentation process uses a scoring knife or a scoring die to press out score lines on the sheet material through pressure, so that the sheet material can be bent and formed at a predetermined position. The marks pressed by this method are mostly straight lines, so it is called scoring. Generally speaking, the die-cutting and indentation process often combines the die-cutting knife and the scoring knife in the same template and performs die-cutting and indentation processing on the die-cutting machine at the same time, so it can be simply referred to as die pressing. The die pressing processing technology is mainly used to perform die-cutting and indentation on various papers or boards, and can also perform die-cutting and indentation processing on leather and plastic materials.

The utility model provides elastic force by arranging a spring piece on the bearing part of the bottom plate body for carrying the sheet material, and pushes out the sheet material stuck in the scoring groove, avoiding the adhesion between the sheet material and the scoring bottom plate, avoiding the damage of the sheet material during the feeding process due to adhesion, and improving the qualified rate. The spring piece providing the separation elastic force is only composed of a connecting part connected to the bottom plate body, a deformation part providing deformation and a contact part holding the sheet material, with a simple structure and low cost. However, the scoring groove in this scheme is not through, which needs to be improved.
