1. Mechanical structure configuration
1. Body frame
Material: High-strength cast iron or steel plate welded structure, annealed to eliminate internal stress, ensure body rigidity, and reduce vibration during operation (such as HT300 cast iron material, high hardness and strong wear resistance).
Structural design:
Integral frame structure, integrated design of stamping platform and frame to ensure uniform pressure distribution.
Some high-end models adopt gantry structure to improve lateral stability and are suitable for large-size processing.
2. Stamping platform
Surface treatment: The surface of the platform is ground, electroplated with hard chrome or sprayed with Internationally renowned brands to ensure flatness (flatness ≤ 0.02mm/m) and prevent material adhesion.
Heating function (optional): Some models have built-in heating tubes on the platform to control the temperature (such as 60-120ºC), suitable for materials that require hot pressing (such as PVC, leather).
3. Pressure system
Pressure type:
Mechanical pressure: Provide constant pressure through crank-connecting rod mechanism or cam drive (common pressure range: 10-200 tons).
Hydraulic pressure: Driven by hydraulic cylinder, the pressure is adjustable and stable, suitable for high-precision indentation (such as hydraulic system pressure error ≤±0.5MPa).
Pressure uniformity: The pressure plate is equipped with a pressure equalizing device (such as elastic pad, hydraulic balancing valve) to ensure that the full-width pressure deviation is ≤±1%.
2. Power and transmission system
1. Drive motor
Type:
Ordinary model: Adopt three-phase asynchronous motor, with frequency converter speed regulation (speed range 10-60 times/minute).
High-end model: Servo motor drive (such as Panasonic, Mitsubishi servo system), high positioning accuracy (±0.01mm), fast response speed, suitable for high-speed continuous production.
Power: Match according to equipment specifications, such as the model with a processing width of 800×1000mm, the motor power is usually 5.5-7.5kW.
2. Transmission mechanism
Gear transmission: The main transmission adopts hardened gears (such as 20CrMnTi carburized and quenched), with high transmission efficiency (≥95%) and low noise (≤75dB).
Belt drive: Some auxiliary mechanisms (such as feeding rollers) adopt synchronous belt drive to avoid slipping and ensure feeding accuracy.
III. Control system
1. Main control system
PLC controller: Siemens, Omron and other brand PLCs are adopted to support program editing and parameter storage (more than 50 sets of process parameters can be saved) to achieve automatic control.
Touch screen: Color touch screen (such as 10.1-inch industrial-grade touch screen), intuitive interface, can set parameters such as indentation depth, tangent speed, feeding length, etc.
2. Positioning and detection system
Photoelectric positioning: Equipped with infrared photoelectric sensors, the edge of the material or the printed mark point is detected to achieve automatic registration (registration accuracy ≤±0.3mm).
Encoder: The feed shaft is equipped with a high-precision encoder (such as 1024 lines) to feedback displacement data in real time to ensure accurate feeding length.
Visual inspection (high-end configuration): Equipped with a CCD visual system, it automatically identifies the material position and corrects the mold offset, which is suitable for complex pattern processing.
IV. Mold and clamping system
1. Mold type
Indentation mold: It uses a steel knife or laser engraving mold with a blade angle of 30°-45° and a hardness of HRC58-62, which is suitable for paper indentation (such as 300-1500g/m² cardboard).
Tangent mold: High-speed steel or carbide blades, with sharp blades and good wear resistance, can cut thick materials such as leather and plastic.
2. Clamping and adjustment
Quick clamping: The mold base is equipped with a T-slot or positioning pin, and cooperates with a manual/pneumatic clamping device to achieve quick mold replacement (replacement time ≤10 minutes).
Pressure adjustment: There is a fine-tuning screw (accuracy 0.01mm) above the mold, which can adjust the local pressure separately to meet the indentation depth requirements of different areas.
V. Feeding and receiving system
1. Feeding mechanism
Manual feeding: Simple models use manual feeding, which is suitable for small batch production.
Automatic feeding:
Suction feeding: The suction belt or suction nozzle absorbs the material to avoid slipping (suitable for thin paper, such as 80-300g/m²).
Roller feeding: The rubber roller presses the material and is driven by a servo motor. The feeding length error is ≤±0.5mm (suitable for thick paper or board).
Feeding width: The maximum feeding width depends on the machine model, such as 500-1200mm for common models.
2. Receiving mechanism
Automatic receiving table: Equipped with a stacking device, the receiving quantity can be set, and an alarm will be automatically triggered when the material is full.
Waste recovery: The waste generated by cutting is collected through a suction duct or conveyor belt to keep the working environment clean.
Six. Auxiliary functions and safety configuration
1. Auxiliary devices
Dust removal system: A suction fan is installed under the stamping platform to remove paper scraps and dust in time to avoid affecting the processing accuracy.
Lubrication system: The automatic grease pump supplies oil to the transmission parts (such as guide rails and bearings) at a regular interval to reduce wear (lubrication cycle can be set).
Waste cutting: The tangent waste edge is equipped with a rotary cutter to cut off long waste for easy collection.
2. Safety protection
Emergency stop button: Red emergency stop buttons are set at multiple locations on the machine body, and the machine can be stopped immediately in case of failure.
Overload protection: Motor overload protector and hydraulic system pressure safety valve to prevent equipment damage.
Safety light curtain: An infrared light curtain is installed in front of the stamping area, and the machine automatically stops when a human body approaches (response time ≤ 0.1 seconds).
Seven. Optional configuration and customized functions
Die-cutting and creasing machine: Integrated die-cutting, creasing, and tangent functions, suitable for complex packaging processing.
Fully automatic connection system: connect to printing machines, folder gluers and other equipment to realize assembly line production (such as adding automatic conveyor tables and stackers).
Environmental protection configuration: exhaust gas treatment device (suitable for processing materials such as PVC), noise reduction and sound insulation cover (noise ≤70dB).
VIII. Configuration selection suggestions
1. Small batch processing: choose mechanical pressure + manual feeding model, low cost and simple maintenance.
2. Large batch production: give priority to servo motor + automatic feeding + visual positioning to improve efficiency and precision.
3. Special materials: such as processing leather and metal foil, heating platform and carbide mold are required.
