Description

Technical Field

[0001] The present invention relates to the technical field of plastic-steel door and window cutting, and more particularly to an energy-saving plastic-steel door and window cutting device. Background Art

[0002] With the rapid development of the construction industry, plastic-steel doors and windows are widely used in the market due to their excellent thermal and sound insulation properties and low cost. The cutting process is a key step in the production and processing of plastic-steel doors and windows. Its processing quality and efficiency directly affect the performance and production efficiency of the finished doors and windows.

[0003] At present, most traditional plastic-steel door and window cutting devices have problems such as low automation, insufficient cutting accuracy, and high energy consumption. Many devices use manual clamping of raw materials, which is not only cumbersome and inefficient, but also difficult to ensure the consistency of clamping force, which can easily cause the plastic-steel raw materials to shift during the cutting process, affecting cutting accuracy and product qualification rate. In terms of cutting power, some equipment relies on a single mechanical drive and cannot flexibly adjust the cutting force according to material properties and cutting requirements. While causing energy waste, it also accelerates tool wear and increases production costs. In addition, traditional devices lack a complete detection and feedback mechanism, making it difficult to achieve real-time monitoring and precise control of the cutting process, limiting the level of intelligent and automated production. These technical bottlenecks make it difficult for traditional cutting devices to meet the modern construction industry's demand for efficient, high-precision, and energy-saving production of plastic-steel doors and windows. Therefore, in order to solve the above problems, the existence of an energy-saving plastic-steel door and window cutting device is crucial. Summary of the Invention

A first clamping plate 35 is fixedly arranged on one side of the four first electric telescopic rods 34, and is fixedly clamped on both sides of the plastic-steel raw material 4 by the first clamping plate 35. The four first clamping plates 35 are fixedly provided with a first clamp pressure sensor 302 on the side facing the plastic-steel raw material 4. A plurality of tooth grooves 22 are opened on the outside of the processing table 2, and a first gear 18 is fixedly arranged on the top of the flip control motor 17, and the first gear 18 is meshed and connected with the tooth groove 22; The first clamp pressure sensor (302) provides real-time feedback of the clamping force, and the system dynamically adjusts the stroke of the first electric telescopic rod (34).

The clamping force error is smaller, deformation of the profile is avoided, and the qualified rate is effectively improved.

[0023] Specifically, screw rods 5 are fixedly provided on both sides of the slide rail 32, and a displacement sensor 50 is fixedly provided on one side of the screw rod 5. The top of the slide rail 32 is slidably connected to a second clamping plate 33 through the screw rod 5.

[0025] Specifically, circular arc grooves 23 are provided on both sides of the top of the processing table 2, and racks 301 are fixedly provided at the bottom of the two rotating disks 30.

[0027] Specifically, the system control center adopts an STM32 microcontroller as a core control component, and the STM32 microcontroller is respectively connected to the power module, sensor module, human-computer interaction module, execution drive module and communication module, and the power module includes an AC / DC adapter, a 24V main power supply, a 12V voltage stabilizing circuit, a 5V voltage stabilizing circuit and a 3.3V voltage stabilizing circuit. The AC / DC adapter converts external alternating current into a 24V main power supply, and the 24V main power supply is converted into 12V, 5V and 3.3V voltages respectively by a 12V voltage stabilizing circuit, a 5V voltage stabilizing circuit and a 3.3V voltage stabilizing circuit to power the system control center, the sensor module and the execution drive module; The AC / DC adapter converts mains power to 24V, which is then output via a voltage stabilization circuit as 12V (motor drive), 5V (sensor), and 3.3V (MCU). The STM32 consumes less than 2mA in sleep mode, achieving 80% energy savings in standby mode.

The output end of the signal conditioning circuit is connected to the ADC input channel of the system control center. The angle encoder is connected to the SPI interface of the system control center through the encoder interface circuit. The sensor outputs a weak signal (0.5-5mV), which is processed by an amplifier (gain 100-1000 times) and a low-pass filter (cut-off frequency 10kHz) and then converted into a digital signal by the ADC. The angle encoder transmits data to the STM32 via the SPI interface at a rate of 1MHz.

The touch control screen (15) communicates with the STM32 via UART at a rate of 115200bps. The operation button triggers a GPIO interrupt. When the system detects an overload (such as current > 5A), the buzzer (1kHz pulse) and indicator light (flashing red) are driven via GPIO. The parameter setting time is shortened by 70% (compared to traditional button operation), and the fault response time is <100ms, reducing the risk of equipment damage.

The STM32 controls the stepper motor (subdivided into 1 / 256 steps) and servo motor (position loop PID adjustment) through PWM (frequency 20kHz). The GPIO output high and low levels drive the micro hydraulic pump controller and solenoid valve to achieve proportional control of cutting force and clamping force. The stepper motor positioning accuracy reaches ±0.01°, the servo motor speed fluctuation is less than ±0.5%, and the hydraulic response time is less than 50ms, realizing dynamic force compensation.

[0031] Specifically, the communication module includes an RS485 communication module, a WiFi module and an Ethernet interface. The RS485 communication module and the WiFi module are connected to the system control center via a UART interface. The Ethernet interface is connected to the system control center via an Ethernet controller to realize remote monitoring and data uploading of the control system. The system control center controls the micro hydraulic pump 19 to assist in adjusting the cutting force according to the pressure signal detected by the manual sensor 12 and the optimal cutting force corresponding to the preset material type. The position of the second clamping disk 33 is adjusted by the servo motor according to the position signal of the second clamping disk 33 detected by the displacement sensor 50 and the preset cutting length.
