Briefly introduce: What are the technical characteristics of the special bottom die machine for knife die?

The special bottom die machine for knife die is the key equipment to adapt to the die-cutting process in packaging and printing industries. Its technical characteristics focus on high precision, high efficiency and multi-function, which meets the needs of modern large-scale production. The following is a concrete introduction:

High machining accuracy: this kind of equipment is equipped with high-speed and high-precision spindle, and the maximum rotation speed can reach 60000RPM. It is matched with high-quality imported screw and guide rail to ensure machining accuracy. The machining accuracy of some models is ±0.02mm, the repetition accuracy is ±0.01mm, and the spindle runout accuracy is less than 0.005 mm. At the same time, the follow-up machining method is adopted to solve the problem of controlling the slotting depth and avoid the influence of plate difference on machining stability. Some steel bottom dies will also be designed with strip-shaped or grid-shaped anti-slip grooves to reduce paper slip during die-cutting and further improve the molding quality.

Outstanding machining efficiency: the equipment is generally equipped with multiple spindles and multiple tool holders. For example, some machines are equipped with five knives to be responsible for grooving and polishing positioning holes respectively, while others are equipped with 1.2KW high-speed spindle with automatic tool changing and six tool holders. The software can automatically plan the machining sequence and path without frequent manual tool changing and adjustment. Moreover, it only takes 10 minutes to die-cut and proofread a single product, which greatly shortens the adjustment time compared with the traditional method and adapts to the high-speed box pasting rhythm of 400 meters per minute.

Convenient and easy to use: most of them are equipped with self-developed special software and adopt Windows interface, which can automatically generate indentation strips and typeset and cut them according to the die drawing, without complicated numerical control instructions. This not only reduces the dependence on the experience and technology of die-cutting masters, avoids the bottleneck of employment, but also makes the adjustment operation more standardized, and novices can operate after simple training.

Multifunctional and flexible: it has the multi-purpose feature of one machine. Besides the core bottom cutting die, it can also realize drawing, tape cutting, proofing and other functions. Drawing function can be used for printing color position proofreading, machine embossing and bronzing alignment, etc. After the vibration cutter head is selected, the rubber strip can be cut accurately. Its processing width is also suitable for the mainstream demand, such as 1200*1000mm, and it can be used to process full-width bottom die materials.

Stable and durable operation: the whole machine adopts high-quality accessories to ensure stability. For example, the pneumatic system adopts AirTAC brand, which is suitable for high-frequency processing. At the same time, it is equipped with perfect hardware interlocking protection to avoid signal error and damage to the spindle. The bottom die adapts to different materials, and its service life is more than 20,000-500,000 times, which can meet the needs of different die cutting. In addition, excellent dust collection design can avoid splashing of waste during processing, which not only keeps the surface of the material clean, but also reduces the influence of waste on equipment and processing accuracy.
