A Lubricated Round Knife Die Cutting Fixture

Abstract

The invention belongs to the technical field of mechanical jig equipment, and relates to a lubricating type circular-knife die cutting jig. The main body structure of the lubricating type circular-knife die cutting jig comprises a circular knife, a steel shaft, a rubber shaft, a sponge shaft, limiting rings, positioning rings, bearings, clamping grooves, a base body, a knife point and knife rests; the circular knife is arranged on the upper part of the base body; the knife point is arranged on the periphery of the circular knife; the knife rests are arranged on the left end and the right end of the circular knife respectively; the circular knife is fixedly connected to the base body through the knife rests; the steel shaft is arranged at the lower part of the base body; the rubber shaft and the sponge shaft are arranged at the top of the base body, wherein the rubber shaft and the sponge shaft are of cylindrical structures, the rubber shaft of a rubber coating type structure is arranged at the lower part, and the rubber shaft is arranged at the upper part; the left end and the right end of the rubber shaft are connected to the left end and the right end of the sponge shaft respectively through the bearings and the clamping grooves; and the limiting rings and the positioning rings are arranged at the positions, located on the inner sides of the bearings, of the left end and the right end of the rubber shaft respectively, wherein the limiting rings and the positioning rings are of circular ring structures. The lubricating type circular-knife die cutting jig is simple in structure, reliable in principle, novel in design, simple and convenient to operate, wide in application range, friendly to use environment, good in cutting effect and high in cutting efficiency.

Description

Technical field: [0001] The invention belongs to the technical field of mechanical jig equipment, and relates to a lubricating round knife die-cutting jig, which is used to assist in the production of polymer adhesive tapes, and to avoid glue sticking to the knife, adhesive sticking back and glue in the process of die-cutting and molding production and processing. spillover phenomenon. Background technique: [0002] Polymer tapes used to bond components of electronic products are developing in the direction of diversification and specialization with the development of the electronics industry. The adhesives on polymer tapes are becoming thinner, more fluid and thicker. It is also getting bigger and bigger; the die-cutting method of die-to-glue in the prior art is troubled by sticking knife, adhesive back-adhesion and glue overflow, which leads to the bad situation of glue deformation and glue overflow, and even cannot produce and process polymers. Polymer tape, this problem...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art, solve the problems of glue sticking to the knife, adhesive sticking back, glue overflow and deformation during the die-cutting molding process of the polymer tape, and seek to design a lubricated round knife die-cutting fixture
