Description

Technical Field

[0001] This utility model relates to the field of cutting tooling technology, and in particular to a cutting tooling for automotive air conditioning ducts. Background Technology

[0002] Automotive air conditioning ducts are usually manufactured using injection molding. After production, the excess material at the ends often needs to be trimmed to meet design and installation requirements.

[0003] Before duct cutting, the air conditioning ducts need to be fixed in place. However, some cutting equipment cuts the air conditioning ducts from top to bottom. This design requires the duct positioning mechanism to have an additional structure to avoid the cutting mechanism, which makes the cutting structure of the tooling more complex and costly.

[0004] For example, Chinese patent application CN201720012406.0 discloses an automotive air conditioning duct cutting fixture, specifically stating that "the cutting positioning mechanism can drive the cutting mechanism to move vertically up and down, thereby pressing the duct and confining it within the cutting area of ​​the cutting mechanism." "The first cutting component includes a first cutting mounting seat fixed to the upper surface of the cutting fixing plate, on which a first cutting cylinder is fixed, and the end of the first cutting cylinder is connected to a first cutting blade. The second cutting component includes a second cutting mounting seat fixed to the upper surface of the cutting fixing plate, on which a second cutting cylinder is fixed, and the end of the second cutting cylinder is connected to a second cutting blade." The cutting positioning mechanism is used to fix the duct; the first and second cutting components cut the end of the duct from top to bottom. This design requires the cutting positioning mechanism to have a structure to allow for clearance between the first and second cutting components, resulting in a complex cutting structure and higher cost for the fixture.

As a preferred embodiment, a grinding layer is provided on the sides of the first cutter 25 and the second cutter 34. This grinding layer can polish the cut of the duct. The grinding layer can be a grinding mark formed by cutting the side of metal, or it can be sandpaper, a file, a matte coating, etc. The grinding layer slightly protrudes from the sides of the first cutter 25 and the second cutter 34.
