Description

Technical Field

[0001] This utility model relates to the field of sheet metal cutting technology, specifically a PC sheet metal cutting and positioning structure. Background Technology

[0002] PC sheet, also known as polycarbonate sheet, polyester sheet, or Kapron sheet, is a high-tech, energy-efficient, and environmentally friendly plastic sheet with excellent comprehensive performance. It boasts high transparency, lightweight, impact resistance, sound insulation, heat insulation, flame retardancy, and aging resistance. It is a widely used plastic building material internationally, offering advantages unmatched by other building and decorative materials (such as glass and acrylic glass). When using PC sheets, a cutting device, typically a laser cutter, is used to cut them into the desired shape. However, traditional laser cutters lack effective limiting and pressing structures. If the PC sheet is subjected to external impact during cutting, it is prone to displacement, affecting cutting accuracy and finished product quality.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

Detailed Implementation

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example: Those skilled in the art shall connect all electrical components and their compatible power supplies in this case with wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence shall refer to the working principle described below, in which the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0021] Please see Figure 1-3 In order to solve the problem that traditional laser cutting machines lack an effective limiting and pressing structure, and that if the PC sheet is subjected to external impact during the cutting process, the PC sheet is prone to displacement, affecting the cutting accuracy and the quality of the finished product, this technical solution is designed. The detailed technical solution is as follows:

[0022] A PC sheet cutting and positioning structure includes a base 1, a movable gantry laser cutting end 2 on the base 1, multiple crossbeams 3 on the base 1, a cutting platform 4 on the multiple crossbeams 3, and a positioning and anti-slip structure on the cutting platform 4.

[0023] It should be noted that the mobile gantry laser cutting end 2 can move on the base 1 and can perform laser cutting. Multiple crossbeams 3 can be installed on the base 1 by welding or other methods. The cutting platform 4 can also be installed on the base 1 by welding or other methods, as long as the installation relationship is met. The installation method will not be described in detail here. The structure and working principle of the base 1 and the mobile gantry laser cutting end 2 are existing technologies. For details, please refer to the fiber laser cutting machine produced by Jinan Bond Laser Co., Ltd. Since they are existing technologies, they will not be described in detail here.

[0024] Specifically, the positioning and anti-slip structure includes two limiting components symmetrically arranged at both ends of the cutting platform 4, and the limiting components are equipped with pressing components;

[0025] Specifically, the limiting component includes an end limiting plate 5, which is movably attached to the upper wall of the cutting platform 4. A connecting frame 6 is installed on the end limiting plate 5, and an installation plate 7 is provided at one end of the connecting frame 6. A first electric push rod 8 is installed on the installation plate 7, and the first electric push rod 8 is fixedly installed on the lower wall of the cutting platform 4. Two strip-shaped notches 9 are opened on the end limiting plate 5.

[0026] Specifically, the pressing assembly includes an H-shaped movable frame 10, which is movably inserted into two strip-shaped notches 9. A second electric push rod 11 is installed on the H-shaped movable frame 10, and the second electric push rod 11 is fixedly installed on the movable frame.

[0027] It should be noted that when the device is in the cutting state, the first electric push rod 8 is in the extended state, the second electric push rod 11 is in the retracted state, the end limiting plate 5 is located at one end of the cutting platform 4, and the H-shaped moving frame 10 is located at the upper part of the strip notch 9. The PC sheet is placed on the cutting platform 4. By retracting the first electric push rod 8 on both sides, the end limiting plates 5 on both sides move towards the center of the cutting platform 4 until they are clamped at both ends of the PC sheet. Then, by extending the second electric push rod 11, the H-shaped moving frame 10 moves between the two strip notches 9 until it is pressed against the upper wall of the PC sheet, thereby limiting and fixing the PC sheet to prevent it from moving and ensuring cutting accuracy and finished product quality.

[0028] As a preferred and further option, the base 1 is provided with a control panel 12, which has a built-in microcontroller. The microcontroller can be programmed with software and the control program can be written to control the device. Since this is existing technology, it will not be described in detail here.

[0029] As a preferred and further option, there are two connecting frames 6 to ensure the stability of the end limiting plate 5 during installation. Each connecting frame 6 is movably fitted with an installation block 13, which is fixedly installed on the lower wall of the cutting platform 4 to guide and support the movement of the connecting frame 6 and to protect the telescopic end of the first electric push rod 8.

[0030] As a preferred and further option, a first pressure sensor 14 is provided between the connecting frame 6 and the end limiting plate 5. When the first electric push rod 8 retracts, when the end limiting plate 5 is attached to the PC sheet, the first pressure sensor 14 detects that the pressure value has reached the set value, which means that the PC sheet is clamped in place, and the control panel 12 controls the first electric push rod 8 to stop working.

[0031] As a preferred and further option, a second pressure sensor 15 is provided between the telescopic end of the H-shaped movable frame 10 and the second electric push rod 11. When the second electric push rod 11 extends, when the H-shaped movable frame 10 is attached to the PC sheet, the second pressure sensor 15 detects that the pressure value has reached the set value, which means that the PC sheet is pressed in place, and the control panel 12 controls the second electric push rod 11 to stop working.

[0032] As a preferred and further option, guide rods 16 are installed on both strip-shaped notches 9, and H-shaped movable frames 10 are movably fitted onto the guide rods 16. When the second electric push rod 11 extends or retracts, the H-shaped movable frames 10 move on the guide rods 16 to prevent the H-shaped movable frames 10 from tilting and to protect the extension and retraction ends of the second electric push rod 11.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
