Combined type adjustable frame-hollowed die pressing steel die

Abstract

The invention relates to a combined type adjustable frame-hollowed die pressing steel die which comprises a die pressing plate set and a connecting button. The die pressing plate set comprises a positioning die pressing plate and a driven die pressing plate, wherein the driven die pressing plate is located on the side face of the positioning die pressing plate. The positioning die pressing plate comprises positioning handles, a steel die body, a hollowed area, a die pressing area and steel tool groove lines. The positioning handles are located on the left side and the upper side of the steel die body correspondingly. The hollowed area is located at the left half portion of the steel die body, and the die pressing area is located on the right side of the hollowed area. The steel tool groove lines are located on the outer side of the hollowed area and the outer side of the die pressing area correspondingly. The connecting button is located between the parts of the die pressing plate set. The above die pressing steel die can be assembled and combined according to needs and is flexible to operate, long in service life, high in precision, high in production efficiency and low in production cost and labor intensity.

Description

technical field [0001] The invention relates to the technical field of printing and cross-cutting process equipment, in particular to a combined adjustable frame hollow molding steel mold. Background technique [0002] At present, the templates for cross-cutting in the printing process can be roughly divided into wooden molds, fiber molds and ordinary steel molds. Wooden formwork is a formwork made of wood as raw material. There are many inconveniences in the use of wooden molds: First, the size of wooden molds will be affected by air temperature and temperature, so that the size of the wooden molds will change, resulting in possible errors in processing. The second is that the wooden mold is easy to deform. In the process of processing, it is inevitable to encounter bumps, and the wooden material is easy to cause damage and deformation. For the strict printing process, it may cause product errors and inaccuracies, or delay production and cannot be used. The 3rd, service ...

Problems solved by technology

There are many inconveniences in the use of wooden molds: First, the size of wooden molds will be affected by air temperature and temperature, so that their dimensions will change, resulting in possible errors in process processing

Second, the wooden mold is easy to deform

In the process of processing, it is inevitable to encounter bumps, and the wooden material is easy to cause damage and deformation. For the strict printing process, it may cause product errors and inaccuracies, or delay production and cannot be used.

Third, the service life is low

First, because of the material, the strength and rigidity of the fiber formwork are too small, and its static bending strength and static bending elasticity are smaller than other formworks. The fiber plastic formwork used in China is lower in strength and rigidity than wood formwork.

The second is that the load capacity of the fiber formwork is low, and the load is too heavy to easily cause damage to the formwork, which also reduces production efficiency

Third, compared with steel and wood, fiber (plastic) formwork has a larger coefficient of thermal expansion and contraction, which is greatly affected by temperature. For example, in summer high temperature period, as the temperature rises, the 3m long fiber (Plastic) board stretches up to 3mm-4mm, resulting in errors in the process

Fourth, the high-temperature slag produced during the process of production is easy to scald the plastic building formwork, and it is easy to scald the surface of the board and affect the surface quality, thereby increasing certain production difficulties

One is that the ordinary steel formwork is thick and heavy due to its material, and it is inevitably inconvenient to use

Second, the price of ordinary steel formwork is relatively high, the one-time investment in purchase is large, the cost recovery period is long, and regular maintenance must be strengthened, which also indirectly increases labor costs and time costs

The third is that the ordinary steel formwork has low flexibility and cannot be adjusted according to the paper size of offset printing, and it will continue to cause certain wear and tear during the production process. The number of times to replace the cutting steel knife is only about 10 times, and the service life is not long. , and the accuracy will also decrease with the increase of the number of replacements

[0005] In addition, the above templates all have the same operation, and there is a problem that the error is difficult to adjust

Furthermore, the continuous replacement of cutting blades not only causes damage to the template, but also slowly increases the gap between the steel knife lines, resulting in loosening of the steel knife slot, which eventually makes the accuracy inaccurate, and even replaces the template

This not only reduces the production efficiency but also increases the production cost
