Description

Technical Field

[0001] The utility model relates to the technical field of automobile roof production, in particular to a cutting edge structure for die cutting the fabric of a roof fitting die. Background Art

[0002] After the automobile roof is pressed and formed, it is necessary to remove the excess fabric. At present, there are various cutting methods, such as die cutting, water jet cutting, laser cutting, etc. However, since the fabric is a soft material with poor rigidity, the fabric will shake under the impact of the jet during water jet cutting, making it difficult to ensure the cutting accuracy and unable to meet the requirements of occasions with high dimensional accuracy requirements; the working temperature of laser cutting is high, and it is easy to cause burns and charring around the cutting area. Moreover, the roof fabric is a flammable item, with relatively large potential safety hazards; although the cutting edge of a conventional die can meet the punching accuracy requirements, generally, to ensure sufficient strength, the cross-section of the cutting edge is generally triangular, with a tip of about 0.5 mm and a root of up to 1 mm, resulting in a large contact area between the cutting edge and the fabric. The fabric adhesive will adhere to the cutting edge, and when the product is taken out, it is extremely easy to cause deformation and tearing of the product due to pulling. Therefore, for the cutting conditions of roof fabric with high precision requirements, the current cutting methods all have defects and need to be improved. Summary of the Utility Model

[0005] A cutting edge structure for die cutting the fabric of a roof fitting die includes a fitting upper die and a fitting lower die. Blade fixing blocks arranged corresponding to the positions of the roof product to be cut are embedded on the die closing surface of the fitting lower die. Lower die blades are arranged on the blade fixing blocks. The lower die blades are in the shape of thin sheets. An upper die knife rest for cooperating with the lower die blades to complete die cutting is embedded on the die closing surface of the fitting upper die.

[0006] As an optional solution, a lower groove for installing the blade fixing blocks is arranged on the die closing surface of the fitting lower die. The blade fixing blocks are fixedly connected to the bottom of the lower groove through bolts; an upper groove for installing the upper die knife rest is arranged on the die closing surface of the fitting upper die. The upper die knife rest is press-fitted into the upper groove.

[0007] As an optional solution, a slot for installing the lower die blades and a locking hole perpendicular to the slot are arranged on the blade fixing blocks. A plug is arranged in the locking hole. The tail end of the lower die blade is inserted into the slot and locked by the plug.

[0008] As an optional solution, the upper die knife rest is made of nylon material.
