What are the technical characteristics of the die carving machine in packaging L industry?

The precision carving machine for packaging die is a high-precision numerical control equipment specially designed for packaging die (such as carton die cutting die, color box laser die, plastic-absorbing die, etc.). Its technical features are developed around five cores: high processing precision, wide material adaptability, strong process adaptability, intelligent operation, efficiency and stability, and accurately match the processing requirements of packaging die with "complex lines, fine cutting edges and multi-material substrates", as follows:

First, the machining accuracy is high: the precision of the cutting edge and grain of the knife die is guaranteed.

The packaging die requires strict precision (such as the error of blade spacing and the deviation of grain depth directly affect the subsequent die-cutting quality), and the equipment realizes high-precision processing through multiple technologies:

Leading core precision parameters

Positioning accuracy: ≤±0.01mm (high-precision ball screw+linear guide rail, transmission gap ≤0.005mm, to avoid positioning deviation caused by "jumping" in operation);

Repeated positioning accuracy: ≤±0.005mm (it supports the consistency of accuracy when machining the same die for many times, and is suitable for batch die production);

Roughness of machined surface: Ra≤0.8μm (there is no burr or edge collapse after cutting the cutting edge, and no subsequent manual polishing is needed, which directly meets the "sharpness" requirement of die cutting).

High precision drive and control

Servo drive system (such as Panasonic and Yaskawa servo motors) is adopted, with a wide speed adjustment range (0-18,000 r/min), and the cutting speed can be flexibly adjusted according to the material of the die (such as steel, aluminum and wood), so as to avoid substrate deformation caused by high-speed cutting or rough edge caused by low-speed cutting;

With numerical control system (such as New Generation and Fanuc), it supports fine control of "pulse equivalent of 0.0001mm" and can process complex die lines (such as arc-shaped cutting edge, special-shaped hole position and tiny positioning hole).

Second, a wide range of materials: covering the mainstream substrate of the packaging die.

The base materials of packaging die are diverse (to be selected according to the material and thickness of die-cutting products), and the equipment adapts to various base materials through "multi-tool compatibility+adjustable processing parameters":

Advantages of equipment adaptation in typical application scenarios of substrate types

Die-cutting dies for steel-based cartons/color boxes (such as the die base plate inlaid with wood and steel knives and all-steel die) support carbide cutting tools, and can process steel cutting edge grooves (groove width accuracy is ±0.02mm) to meet the processing requirements of high-hardness substrates.

Lightweight cutter dies of aluminum substrate (such as PET box and tissue paper die cutting) adopt high-speed milling technology, which has high cutting efficiency (the processing speed of aluminum substrate can reach 8-15m/min), and the processed aluminium scrap is easy to clean.

Simple die for wood/paper substrate (such as die for trial production of corrugated box) supports low rotation speed and large feed rate processing, avoiding "splitting" of wood substrate and no delamination of paper substrate.

Special cutter dies made of composite materials (such as the bottom plate of the cutter die with rubber buffer layer) can avoid interlayer separation of composite materials by switching parameters (such as reducing cutting depth and adjusting cutter speed).

Third, the process adaptability is strong: it meets the diversified processing requirements of packaging knife dies.

Packaging die processing is not only "cutting", but also needs to match the special requirements of die-cutting process (such as cutting edge angle, positioning hole and buffer groove). The equipment has multi-process compatibility:

Multi-process integrated machining

It can complete "slotting (mounting groove of cutting edge), drilling (positioning hole, screw hole), milling (special-shaped grain) and engraving (logo character)" of the tool die at one time without transferring to multiple devices, thus reducing the secondary clamping error of the substrate (clamping error ≤0.01mm).

For example, when processing the carton die, "steel die groove milling (groove depth 5 mm 0.02 mm), positioning pin hole drilling (aperture 3 mm 0.01 mm) and die number engraving" can be completed synchronously, and the finished die can be directly output.

Special process support

Adjustable angle of cutting edge groove: it can process "V-shaped groove (angle 30-90) and U-shaped groove", and adapt to different types of die-cutting knives (such as straight-edged knives and inclined-edged knives) to ensure that the knife body is closely attached to the groove body, and there is no "running position" during die-cutting;

Layered processing of deep and shallow grooves: support continuous processing of "deep groove (such as main cutting edge groove)+shallow groove (such as auxiliary positioning groove)" on the same tool die, and automatically switch the cutting depth (depth adjustment accuracy is 0.005 mm) through the numerical control system without changing tools;

Micro-feature processing: it can process micro-positioning holes with a diameter of ≥0.5mm and narrow slots with a width of ≥0.3mm, which meets the fine requirements of precision packaging (such as cosmetic boxes and electronic parts boxes).

Fourth, intelligent operation: lower the threshold and improve the machining efficiency of the knife die.

Digitization and automation of the whole process

Convenient drawing import: mainstream design formats (DXF, AI, CAD) are supported, and manual drawing is not required. The system automatically analyzes the drawing of the die and generates the machining path (the path generation time is ≤5 minutes/complex drawing) to avoid manual programming errors;

Intelligent matching of process parameters: Built-in "Tool Mold Processing Parameter Library" (100+groups of parameters are preset according to the type of substrate and the specifications of the tool mold, such as the cutting speed of steel substrate is 12,000 r/min and that of wood substrate is 8,000 r/min), which can be directly called by novices, and can be customized, modified and stored after proficiency;

Automatic auxiliary functions: equipped with "automatic tool alignment instrument" (the tool alignment accuracy is ±0.002mm, and there is no need to manually measure the tool length), "automatic dust suction device" (real-time cleaning of processing debris to avoid the impact of debris adhesion on accuracy) and "automatic positioning of substrate" (fast fixing of substrate by photoelectric sensor or positioning pin, and positioning time is less than or equal to 30 seconds).

Visual monitoring and fault early warning

Equipped with high-definition industrial camera or display screen, real-time display of machining progress, tool wear status (such as automatic prompt replacement when tool wear exceeds the limit), machining path simulation (preview the path before machining to avoid tool collision);

Fault self-diagnosis function: when the equipment has problems such as "motor overload, broken tool and insufficient air pressure", it will automatically stop and pop up fault codes and solutions (such as "E01-broken tool → check tool holder+replace new tool"), thus reducing maintenance time.

5. Balance efficiency and stability: adapt to the "quick response" demand of packaging industry.

The demand for die in packaging industry often has the characteristics of "small batch, multi-batch, short delivery time", and the equipment meets the demand of quick reaction through "efficient processing+stable operation":

High processing efficiency

High-speed cutting ability: the idle speed can reach 30-50m/min, and the effective machining speed (calculated by steel substrate) can reach 5-10m/min. Compared with traditional manual machining (the efficiency is improved by 10-20 times), the machining time of a single small and medium-sized die (such as 600×800mm) can be controlled within 1-2 hours;

Multi-spindle optional: Some high-end models support "double spindle" or "multi-station" design, and can process two identical/different cutter dies at the same time (for example, the left spindle processes steel cutter dies and the right spindle processes wood cutter dies), further improving the batch processing efficiency.

Long-term stable operation

Strong structural stability: the fuselage adopts "integral casting machine bed" (made of HT300 cast iron, which eliminates internal stress after aging treatment), with high rigidity and good shock resistance (amplitude ≤0.002mm during processing) to avoid the deformation of the fuselage caused by long-term operation;

The core components are durable: the tool holder adopts "ER chuck" (the clamping accuracy is ≤0.003mm, and the repeated clamping consistency is good), and the transmission components such as guide rail and lead screw adopt "dust-proof seal design" (to prevent debris and oil pollution from invading), and the service life can reach 8-10 years, reducing the frequency of downtime and maintenance.

Sixth, adapt to the special needs of packaging knife mold: detail optimization to enhance practicality

Large-size machining capacity

In view of the common "large-scale die" in the packaging industry (such as 1200×1500mm die for cartons), the size of the equipment workbench can be customized (mainstream specifications are 600×900mm, 1200×1500mm and 1500×2000mm), and the workbench has strong bearing capacity (≥500kg), so as to avoid the deformation of the workbench when placing large-scale substrates.
