[0002] Metal filing cabinets are a common type of office furniture used to store documents, materials, and other office supplies. The advantages of filing cabinets include effective dust prevention and protection from harmful substances, effectively preserving archives, and ease of movement. Metal filing cabinets are assembled from multiple welded panels, which can be straight or L-shaped. To meet the installation requirements of metal filing cabinets, the straight panels need to be bent into L-shapes during the production process, requiring bending equipment. Currently, straight panels are bent either by bending machine or manually. Both methods require measuring the verticality and flatness of the bent L-shape with a level after bending, making it impossible to inspect the bent panels during the bending process.

[0025] Example

[0026] like Figures 1-7 As shown, a metal filing cabinet panel bending device includes: an equipment box 1, a bending table 101 installed inside the equipment box 1, an opening 102 on the top of the equipment box 1, a fixing frame 103 installed on the top of the equipment box 1, a bending assembly disposed inside the equipment box 1, the bending assembly including: a lifting cylinder 2, a telescopic rod a 201, a horizontal bending plate 202, a pushing cylinder 203, a telescopic rod b 204 and a vertical bending plate 205, and a detection assembly disposed inside the bending table 101, the detection assembly including: a mounting groove 3, a pressure sensor 301, a controller 302, a buzzer 303 and a sound outlet 304.

[0027] The bottom of the fixing frame 103 is provided with a lifting plate 104, the top of the lifting plate 104 is provided with a threaded hole 105, the threaded hole 105 is internally threadedly connected with a threaded screw rod 106, the top of the fixing frame 103 is provided with a forward-reverse motor 107 connected with the threaded screw rod 106, the bottom of the lifting plate 104 is provided with a pressing rod 108 on each side, and the bottom of the pressing rod 108 is provided with a rubber anti-skid block 109.

[0028] When the plate is bent, the box door outside the equipment box 1 is opened, the bending table 101 in the equipment box 1 is exposed, half of the plate is placed on the bending table 101, and the other half is placed at the bottom of the horizontal bending plate 202. After the plate is placed flat with the bending table 101, the forward-reverse motor 107 is started to drive the threaded screw rod 106 to rotate in the forward direction, the threaded screw rod 106 is threadedly rotated with the threaded hole 105, the lifting plate 104 can be driven to move downward, that is, the lifting plate 104 drives the pressing rod 108 and the rubber anti-skid block 109 to move downward, so that the pressing rod 108 and the rubber anti-skid block 109 penetrate into the equipment box 1 through the opening 102, and the rubber anti-skid block 109 at the bottom of the pressing rod 108 contacts the plate. Since the pressing rod 108 is provided with four rods, the top four sides of the plate can be pressed, the pressure on the plate is uniform, and the plate is prevented from moving sideways. The friction between the pressing rod 108 and the plate can be increased through the rubber anti-skid block 109, so that slipping between the pressing rod 108 and the plate is avoided.

[0029] The bottom of the fixing frame 103 is provided with a lifting plate 104, the top of the lifting plate 104 is provided with a threaded hole 105, the threaded hole 105 is internally threadedly connected with a threaded screw rod 106, the top of the fixing frame 103 is provided with a forward-reverse motor 107 connected with the threaded screw rod 106, the bottom of the lifting plate 104 is provided with a pressing rod 108 on each side, and the bottom of the pressing rod 108 is provided with a rubber anti-skid block 109.

[0030] After one end of the plate is tightly pressed and fixed on the bending table 101, the lifting cylinder 2 is started to drive the telescopic rod a 201 to move downward, the telescopic rod a 201 pushes the horizontal bending plate 202 to move downward to contact the other half of the plate, the horizontal bending plate 202 is continuously pushed to move downward to generate pressure on the plate, so that the plate slowly deforms, the contact point between the plate and the bending table 101 forms a bending angle, that is, the slowly deformed plate and the outer side of the bending table 101 will be mutually attached, when the plate bending and the outer side of the bending table 101 are attached, the pushing cylinder 203 is started to drive the telescopic rod b 204 to move leftward, the telescopic rod b 204 pushes the vertical bending plate 205 to move leftward to contact the bent plate, the vertical bending plate 205 is continuously pushed to move leftward to generate pressure on the plate, so that the bent plate and the outer side of the bending table 101 are tightly attached together, and the flatness of the bent plate is ensured.

[0031] The bottom of the fixed frame 103 is provided with a supporting plate 110, the bottom end of the threaded screw rod 106 is rotatably connected with the supporting plate 110 through a bearing, and the bottom of the supporting plate 110 is provided with a through hole 111 at a position opposite to the pressing rod 108. When the threaded screw rod 106 is used, the bottom of the threaded screw rod 106 is supported and placed by the supporting plate 110. During the rotation of the threaded screw rod 106, the bottom end of the threaded screw rod 106 is rotatably connected with the supporting plate 110 through a bearing, so that the threaded screw rod 106 can be normally rotated and used. When the lifting plate 104 drives the pressing rod 108 and the rubber anti-skid block 109 to move up and down through the supporting plate 110, the pressing rod 108 and the rubber anti-skid block 109 can penetrate through the through hole 111 and enter the opening 102, so that the pressing rod 108 and the rubber anti-skid block 109 have a moving space.

[0032] The bottom of the fixed frame 103 is provided with a supporting plate 110, the bottom end of the threaded screw rod 106 is rotatably connected with the supporting plate 110 through a bearing, and the bottom of the supporting plate 110 is provided with a through hole 111 at a position opposite to the pressing rod 108. When the threaded screw rod 106 is used, the bottom of the threaded screw rod 106 is supported and placed by the supporting plate 110. During the rotation of the threaded screw rod 106, the bottom end of the threaded screw rod 106 is rotatably connected with the supporting plate 110 through a bearing, so that the threaded screw rod 106 can be normally rotated and used. When the lifting plate 104 drives the pressing rod 108 and the rubber anti-skid block 109 to move up and down through the supporting plate 110, the pressing rod 108 and the rubber anti-skid block 109 can penetrate through the through hole 111 and enter the opening 102, so that the pressing rod 108 and the rubber anti-skid block 109 have a moving space.

[0033] The bottom of the fixed frame 103 is provided with a supporting plate 110, the bottom end of the threaded screw rod 106 is rotatably connected with the supporting plate 110 through a bearing, and the bottom of the supporting plate 110 is provided with a through hole 111 at a position opposite to the pressing rod 108. When the threaded screw rod 106 is used, the bottom of the threaded screw rod 106 is supported and placed by the supporting plate 110. During the rotation of the threaded screw rod 106, the bottom end of the threaded screw rod 106 is rotatably connected with the supporting plate 110 through a bearing, so that the threaded screw rod 106 can be normally rotated and used. When the lifting plate 104 drives the pressing rod 108 and the rubber anti-skid block 109 to move up and down through the supporting plate 110, the pressing rod 108 and the rubber anti-skid block 109 can penetrate through the through hole 111 and enter the opening 102, so that the pressing rod 108 and the rubber anti-skid block 109 have a moving space.

[0034] When the plate surface is bent and tightly adheres to the outer side of the bending table 101, if the plate surface is completely adhered to the outer side of the bending table 101, it indicates that the bent plate surface is perpendicular and flat. Since the pressure sensor 301 is installed in the installation groove 3, the pressure sensor 301 is flush with the outer side of the bending table 101, so that the bent plate surface is tightly adhered to the pressure sensor 301. The pressure sensor 301 detects the pressure of the plate surface and sends the detected information to the controller 302. After receiving and processing the information, the controller 302 starts the work of the buzzer 303, so that the buzzer 303 emits a sound to prompt the staff that the plate surface bending is completed. During the plate surface bending process, whether the plate surface is perpendicular and flat can be detected, and it is not necessary to measure the bending angle after bending by using a level, thereby reducing the workload of bending and improving the working efficiency of plate surface bending. Conversely, if the plate surface is not bent and adhered, the plate surface cannot be detected, indicating that the bent plate surface is not flat.

[0035] When the box door is closed, the sound emitted by the buzzer 303 can be transmitted from the sound outlet 304 to the outside of the equipment box 1.

[0036] The model of the pressure sensor 301 can be DP-101A, and the working principle is that the pressure sensor 301 is a sensor or instrument that converts mechanical pressure into electrical signals. It is composed of a pressure-sensitive element and an electronic element. The pressure-sensitive element is used to measure, detect or monitor the applied pressure, and the electronic element converts this information into an electrical output signal. The working principle of the pressure sensor 301 is mainly based on specific physical effects such as resistance, capacitance, strain, etc. The pressure sensor 301 is a mature and conventional technology in the technical field, and the circuit or program of the pressure sensor 301 is not improved in this scheme. The circuit and signal connection between the pressure sensor 301 and the controller 302 also belongs to the public conventional technology, so the circuit and signal connection relationship is not described in detail.

[0037] The model of the buzzer 303 is ESZ-11-A, and the working principle of the buzzer 303 is that the piezoelectric buzzer uses the piezoelectric effect to produce sound. Its internal usually contains a piezoelectric ceramic crystal. When an external voltage is applied to the piezoelectric crystal, the crystal produces mechanical vibration, thereby emitting sound. This vibration is amplified through the resonant cavity of the buzzer. The electromagnetic buzzer uses electromagnetic effect to produce sound. Its internal contains a coil and an iron vibration plate. When alternating current passes through the coil, the coil generates a magnetic field that attracts the iron vibration plate to vibrate. The vibration of the vibration plate forms a periodic compression wave in the air, thereby producing sound.

[0038] The equipment box 1 is installed on one side of the box 4, and the power supply 401 is installed inside the box 4. The power supply 401 is connected to the controller 302 through the wire. When the pressure sensor 301, the controller 302 and the buzzer 303 are used, the power supply 401 is connected to the controller 302 through the wire. The controller 302 is connected to the pressure sensor 301 and the controller 302 through the wire. The back of the box 4 is installed with a power cord connected to the power supply 401. The other end of the power cord is installed with a plug. The plug is inserted into the socket in the room to connect the power supply. The power supply 401, the pressure sensor 301, the controller 302 and the buzzer 303 can be normally powered and used, and the controller 302 can control the pressure sensor 301 and the buzzer 303 switch.

[0039] Working principle:

[0040] When the plate is bent, open the box door outside the equipment box 1 to expose the bending table 101 inside the equipment box 1, place half of the plate on the bending table 101 and the other half on the bottom of the transverse bending plate 202, and then start the forward and reverse motor 107 to drive the threaded screw rod 106 to rotate forward, so that the lifting plate 104, the pressing rod 108 and the rubber anti-skid block 109 are driven to move downward, the pressing rod 108 and the rubber anti-skid block 109 penetrate the opening 102 into the equipment box 1, and the rubber anti-skid block 109 at the bottom of the pressing rod 108 contacts the plate. Since the pressing rod 108 is provided with four, it can press the top four sides of the plate, and the pressure on the plate is uniform, preventing the plate from moving sideways. The friction between the pressing rod 108 and the plate is increased by the rubber anti-skid block 109, preventing slipping between the pressing rod 108 and the plate.

[0041] After one end of the plate is pressed and fixed on the bending table 101, the lifting cylinder 2 is started to drive the telescopic rod a201 to move downward, the telescopic rod a201 pushes the transverse bending plate 202 to move downward to contact the other half of the plate, and the transverse bending plate 202 is continuously pushed to move downward to generate pressure on the plate, so that the plate slowly deforms, and the contact point between the plate and the bending table 101 forms a bending angle, that is, the slowly deformed plate and the outer side of the bending table 101 will be in close contact with each other. When the plate is bent and in close contact with the outer side of the bending table 101, the lifting cylinder 2 is started to drive the telescopic rod b204 to move leftward, the telescopic rod b204 pushes the vertical bending plate 205 to move leftward to contact the bent plate, and the vertical bending plate 205 is continuously pushed to move leftward to generate pressure on the plate, so that the bent plate is tightly attached to the outer side of the bending table 101, ensuring that the bent plate has good flatness.

[0042] When the plate is bent and in close contact with the outer side of the bending table 101, the plate is completely attached to the outer side of the bending table 101, indicating that the bent plate is perpendicular and flat. Since the pressure sensor 301 is installed inside the mounting groove 3 and is flush with the outer side of the bending table 101, the bent plate is in close contact with the pressure sensor 301. The pressure sensor 301 detects the pressure of the plate, sends the detected information to the controller 302, and the controller 302 receives and processes the information and starts the buzzer 303 to work, so that the buzzer 303 emits a sound to prompt the staff that the plate bending is completed. During the plate bending process, it can be detected whether the plate is perpendicular and flat, without the need to measure the bending angle after bending by using a level, reducing the workload of bending and improving the working efficiency of plate bending.
