Description

Special punching device for pulp molded product

Technical Field

The utility model belongs to the technical field of the die-cut of paper pulp molding product, specifically be a special die-cut method of paper pulp molding product and device.

Background

In the pulp molding industry, part of special products need to be hollowed into special shapes on the complete product to meet the use requirements of the product, however, the cavities cannot be realized in the traditional one-step forming process, and the subsequent processing is needed to assist the realization.

Because the product is no longer simple and square, but various irregular surfaces such as arc curved surfaces, inclined surfaces and the like appear, however, the traditional punching process of the pulp molding product is formed by punching through a common bending cutter die, and can only be used for manufacturing some simple common products without irregular surfaces, but the hole cutting of the normal cutter die on the irregular surfaces can cause that the punched product can not achieve the expected effect, and even cracks, burrs and damages of the product appear, as shown in fig. 4, the product is integrally an oval column 100, the thickness of the product is 2mm, a circular cavity 200 is formed on the arc surface of the product, and the circular cavity is rare in a paper-plastic die, and obviously, the product can not be completed by using the cutter die for the following reasons: (1) when a traditional paper pulp molding cutting die is used, the thickness of a product is mostly 0.8-1.2 mm, and when the cutting die is designed, because the problem that whether a blade can perfectly cut through the product is considered, the height of the bending knife extending out of a cutting die template is usually required to be more than the thickness of the products, so that the problem can be solved if the product with the thickness of 2mm is cut: the blade is not easy to cut through when the product material is thick and the blade extends out of the die plate of the cutting die by more than 2mm, and the blade is easier to damage when the blade is used due to the excessively high height, so that the production cost is increased invisibly. (2) The whole product has a special-shaped surface (a cylindrical curved surface in fig. 4), and the special-shaped surface is a special surface of the product, is not a general plane, but has a special shape, such as an arc surface, an inclined surface and the like. And punch on the dysmorphism face, traditional cutter die is difficult to realize the location to this kind of product, and unable accurate location can make the hole dystopy of cutting out can not reach customer's requirement. (3) The cutting needs to be performed on a curved surface, however, the edge of the bending knife of the conventional cutting die is a plane, so that the product is cut off to form unsightly creases, cracks and even damage. (4) The product shape is special, and traditional cutting die can't fix a position fixed this kind of product, must consider how this kind of similar product is fixed and fixed, and the fretwork that just can't realize meeting the requirement of perfect location. To solve this problem, it is necessary to design a special punching method and apparatus for pulp molded products.
