Description

Technical Field

[0001] This application relates to the technical field of molding machines, and in particular, to a multi-functional radio frequency vacuum arc molding machine. Background Art

[0002] In the processing of door, wall and cabinet, in various application scenarios, it is necessary to press or bend wooden boards into bent boards or bent corners with a certain arc surface or angle.

[0003] In the processing of door, wall and cabinet, there are various types of molding machines for pressing or bending wooden boards into bent boards or bent corners with a specific arc surface or angle. A hot press applies a certain pressure and temperature to the wooden board, making the wooden board soften under the action of heat, and then pressing it into the required shape through devices such as molds.

[0004] At present, with the increasing popularity of customized furniture, various special-shaped furniture has emerged. Most customized furniture has many styles or models and a small order volume. Traditional door, wall and cabinet board processing equipment has a single function. When facing customized furniture orders, multiple processing equipment for corresponding styles or models need to be used separately, resulting in a high processing cost and being not suitable for the production of small-batch and multi-style customized furniture. For example, in a traditional hot press, the range and shape of the pressing part have limitations, and there are defects in being unable to flexibly meet the requirements of different specifications and customized styling. Therefore, it is necessary to design a multi-functional radio frequency vacuum arc molding machine. Summary of the Invention

[0005] In order to flexibly handle the processing of plates with different specifications and meet various customized requirements, this application provides a multi-functional radio frequency vacuum arc molding machine.

[0006] The multi-functional radio frequency vacuum arc molding machine provided by this application adopts the following technical solutions: A multi-functional radio frequency vacuum arc molding machine includes an operating table and an upper cover. The upper cover covers the top of the operating table. A silica gel film that cooperates with the operating table to form a closed cavity is covered on the top of the operating table. The silica gel film is located between the upper cover and the operating table. A vacuum pump for evacuating the inside of the closed cavity is provided at the bottom of the operating table; a radio frequency heater is provided on the upper cover.

[0007] By adopting the above technical solutions, the vacuum pump can be used to evacuate the air in the closed cavity to form a vacuum environment. Under the action of atmospheric pressure, the silica gel film closely adheres to the surface of the plate, making it evenly stressed; the radio frequency heater can quickly and evenly heat the plate, softening the plate at a suitable temperature, facilitating flexible handling of plates with different specifications and sizes under vacuum adsorption and the action of molds, realizing the processing of bent plates and bent corners with various complex arc surfaces or angles, meeting the diverse requirements of many styles and small order volumes in the production of customized furniture, effectively solving the problems of single function of traditional processing equipment and inability to flexibly adapt to customized styling, reducing processing costs and improving production efficiency.

[0008] Optionally, a fixed frame is hinged on the operating table. The fixed frame is located between the upper cover and the operating table. A slot is formed on the side wall of the fixed frame facing the operating table. The slot is formed in a circle along the length direction of the fixed frame. The edge of the silica gel film is inserted into the slot. A locking member for locking the silica gel film is arranged on the fixed frame. There are multiple locking members, and adjacent locking members are arranged at intervals along the length direction of the fixed frame.

[0009] By adopting the above technical solution, the slot provides an accurate installation and positioning structure for the silica gel film, facilitating the quick and accurate installation of the silica gel film on the fixed frame. Multiple locking members arranged at intervals can fasten the edge of the silica gel film at multiple points, effectively preventing the silica gel film from shifting or loosening during the operation of the equipment, ensuring a good seal between the silica gel film, the fixed frame and the operating table, and providing a stable and reliable enclosed space for the subsequent vacuum pumping operation and sheet processing.

[0010] Optionally, the locking member includes a fixture and a bolt. The fixture is buckled on the top of the fixed frame. One end of the fixture abuts against the inner wall of the fixed frame, and the other end is threadedly connected with the bolt. The end of the bolt penetrates through the fixture and abuts tightly against the outer wall of the fixed frame.

[0011] By adopting the above technical solution, the combined structure of the fixture and the bolt is simple and convenient to operate. During installation, by tightening the bolt, the silica gel film can be firmly clamped on the fixed frame by the cooperation of the bolt and the fixture, realizing reliable locking and fixing. During disassembly, just loosen the bolt, which is convenient for the replacement and maintenance of the silica gel film. At the same time, this structure can provide a large tightening force to ensure the stability of the silica gel film during the operation of the equipment.

[0012] Optionally, a groove is formed on the fixed frame. The number of grooves formed corresponds to the number of fixtures. The fixture straddling the top of the fixed frame is located in the groove and its top is flush with the top surface of the fixed frame.

[0013] By adopting the above technical solution, the groove provides a hidden installation space for the fixture, making the fixture flush with the top surface of the fixed frame after installation, avoiding the protrusion of the fixture and affecting the sealing fit between the fixed frame and the upper cover and the operating table. At the same time, the groove plays a positioning role for the fixture, ensuring the accuracy of the installation position of the fixture, and further ensuring uniform force when locking the silica gel film, improving the sealing effect and the stability of the equipment operation.

[0014] Optionally, a bottom shell is fixed on the outer wall of the operating table, and a top shell is fixed on the outer wall of the upper cover. An opening is formed at one side of the top end of the bottom shell away from the hinge axis of the fixed frame and the operating table. The length of the opening is the length of the fixed frame, and the depth of the opening is the height of the fixed frame. When the closed cavity is formed, the fixed frame abuts against the top of the bottom shell, and the corresponding position of the fixed frame is located in the opening. A lock for locking the two is arranged between the side wall of the fixed frame close to the opening and the outer wall of the bottom shell.

[0015] By adopting the above technical solution, the notch provides accurate positioning and storage space for the fixed frame. When the fixed frame swings to fit with the operation table to form a closed cavity, it can accurately fall into the notch, ensuring the accuracy of the position of the fixed frame. The lock further firmly locks the fixed frame with the bottom case, preventing the fixed frame from shaking or displacing during the operation of the equipment, enhancing the sealing performance of the closed cavity and the stability of the overall structure, and ensuring the smooth progress of the sheet processing.

[0016] Optionally, a lifting member for lifting the fixed frame upward is provided between the operation table and the fixed frame, and the lifting member is stored in the bottom case.

[0017] By adopting the above technical solution, the lifting member can realize the automatic lifting and lowering of the fixed frame without manual operation, improving the convenience and efficiency of the operation. Storing the lifting member in the bottom case makes the overall structure of the equipment more compact and tidy, avoiding interference or damage caused by the exposure of the lifting member.

[0018] Optionally, a table board is laid on the operation table, and a plurality of ventilation holes are opened on the table board. There is a distance between the table board and the top surface of the operation table, and the suction pipe of the vacuum pump penetrates through the bottom of the operation table to the space between the table board and the top surface of the operation table.

[0019] By adopting the above technical solution, the ventilation holes on the table board can enable the vacuum environment to act on the surface of the sheet quickly, improving the vacuum pumping efficiency and ensuring that the sheet can be subjected to a uniform vacuum adsorption force during the processing. The space between the table board and the top surface of the operation table is convenient for arranging the suction pipe and can make the air flow distribution more uniform, further optimizing the vacuum effect, ensuring that the sheet deforms uniformly under vacuum and heating conditions, and improving the processing quality.

[0020] Optionally, a constant temperature water tank is provided at the bottom of the operation table, and a circulating water pipe is connected to the constant temperature water tank. The circulating water pipe is laid between the operation table and the table board.

[0021] By adopting the above technical solution, the circulating system composed of the constant temperature water tank and the circulating water pipe can adjust the temperature of the operation table, keeping the operation table within a suitable temperature range. This helps to maintain the temperature stability during the heating process of the sheet, avoiding adverse effects on the sheet processing caused by temperature fluctuations of the operation table, ensuring that the sheet softens and deforms in a uniform and stable temperature field, and improving the accuracy and quality of bending and corner processing.

[0022] Optionally, an exhaust fan is fixed on the top case.

[0023] By adopting the above technical solution, the exhaust fan can timely discharge the heat generated during the operation of the radio frequency heater.

[0024] Optionally, the lifting member is a cylinder or an electric cylinder or a hydraulic cylinder.

[0025] By adopting the above technical solutions, the air cylinder, electric cylinder, and hydraulic cylinder all have the characteristics of stable power output and high control precision. They can be flexibly selected according to factors such as actual production requirements and equipment costs. They can provide reliable power support for the swing of the fixed frame, realize the stable and accurate lifting and lowering actions of the fixed frame, meet the requirements of equipment automation operation, and improve the reliability and stability of equipment operation.
