[0002] The TV case refers to the outer shell surrounding the internal components of the TV, which is designed to protect the internal circuits and components from external factors. In particular, the inner shell of the TV is usually made of metal. During production, a bending machine is often used to bend the sheet to form the TV case.

[0003] When the plate is bent by a bending machine, the plate needs to be moved between the pressing plate and the pressing groove of the bending machine, and then the pressing plate is moved downward to bend one side of the plate, and then the plate is rotated and bent again, resulting in the need to flip the plate three times and bend it four times in the manufacture of a TV housing, thus affecting the efficiency of TV housing production.

[0020] Example 1: Please refer to Figure 1-Figure 14 The present invention provides a technical solution: a bending device based on the production of a TV shell, comprising an operating table 1, a support table 11 is fixedly connected to the top of the operating table 1, a lower pressing plate 12 is slidably connected to one side of the support table 11, a hydraulic rod 13 is fixedly connected to one side of the support table 11, a bending mechanism 2 and a flipping mechanism 3 are arranged on the top of the operating table 1, the bending mechanism 2 comprises a forming unit 21, the forming unit 21 is used to bend a plate into shape, wherein the plate is an unformed TV shell, the bending mechanism 2 also comprises a conveying unit 22, the conveying unit 22 is used to convey the unformed TV shell; The flipping mechanism 3 is used in conjunction with the bending mechanism 2, and the flipping mechanism 3 is used to rotate the television housing that has been bent once by ninety degrees.

[0021] As a further limitation of the bending mechanism 2 of the present invention, the forming unit 21 includes a fixed plate 2101 fixedly connected to one side of the lower pressing plate 12, the top of the fixed plate 2101 is fixedly connected to the telescopic end of the hydraulic rod 13, the top of the fixed plate 2101 is fixedly connected to the bottom of the lower pressing plate 12, the number of fixed plates 2101 is two, the bottom of the fixed plate 2101 is slidably connected to two upper plates 2102, the top of the operating table 1 is slidably connected to a lower plate 2103, the number of the lower plates 2103 is the same as the number of the upper plates 2102, and one side of the lower plate 2103 is fixedly connected to the first telescopic rod 21 04, the telescopic end of the first telescopic rod 2104 is fixedly connected to one side of the upper plate 2102, and a bidirectional threaded rod 2105 is rotatably connected to one side of the support platform 11 through a bearing, and the surface of the bidirectional threaded rod 2105 is threadedly connected to the inner cavity of the lower plate 2103, and a guide rod 2106 is fixedly connected to one side of the fixed plate 2101 and one side of the support platform 11, and the inner cavity of the upper plate 2102 and the inner cavity of the lower plate 2103 are slidably connected to the surface of the guide rod 2106, and a pressing plate 2107 is fixedly connected to the bottom of the upper plate 2102, and a groove 2108 is provided on the top of the lower plate 2103. The inner cavity of the groove 2108 is fixedly connected with an electric telescopic rod 2109, and the top of the electric telescopic rod 2109 is fixedly connected with a top block 2110. The surface of the top block 2110 is slidably connected with the inner cavity of the groove 2108. By setting the forming unit 21, when the plate is bent, the plate is moved between the upper plate 2102 and the lower plate 2103, and the fixed plate 2101 and the lower pressing plate 12 are driven downward by the hydraulic rod 13, so that the upper plate 2102 moves downward, thereby driving the pressing plate 2107 to move downward to press the plate. At this time, the electric telescopic rod 2109 is started to drive the pressing plate 2107 to move downward to press the plate. The movable top block 2110 moves upward, and since the top block 2110 and the pressing plate 2107 are not on the same horizontal plane, the effect of bending both sides of the plate is achieved, wherein the bending angle of one side of the plate is adjusted by the distance that the top block 2110 moves upward, and the distance between the two lower plates 2103 can be adjusted by rotating the bidirectional threaded rod 2105. When the two lower plates 2103 move to opposite sides, the upper plate 2102 will move synchronously with the lower plate 2103 under the action of the first telescopic rod 2104, so that TV casings of different sizes can be bent.

[0022] The bottom of the upper plate 2102 is fixedly connected to a connecting plate 2111, the bottom of the connecting plate 2111 is fixedly connected to an extrusion plate 2112, the top of the lower plate 2103 is slidably connected to a pushing plate 2113, the bottom of the pushing plate 2113 is provided with a slider 2114, one side of the slider 2114 is fixedly connected to a first spring 2115, one end of the first spring 2115 is fixedly connected to the inner wall of the lower plate 2103, by setting the extrusion plate 2112, the pushing plate 2113, the slider 2114 and the first spring 2115 are used in coordination, when the upper plate 2102 moves downward, it will drive the connecting plate 2111 and the extrusion plate 2112 to move downward, the extrusion plate 2112 moves downward and squeezes the pushing plate 2113, wherein the bottom of the pushing plate 2113 contacts the top of the lower plate 2103, thereby pushing the plate toward the middle through the pushing plate 2113, thereby achieving the effect of aligning the plate.

[0023] The pushing plate 2113 includes an inclined plate 2116, the bottom of which is fixedly connected to the top of the slider 2114, and an adjusting plate 2117 is movably connected to one side of the inclined plate 2116, and a round rod 2118 is fixedly connected to one side of the adjusting plate 2117, and the surface of the round rod 2118 is slidably connected to the inner cavity of the inclined plate 2116, and an adjusting groove 2119 is provided on the top of the inclined plate 2116, and the inner cavity of the adjusting groove 2119 is threadedly connected with a first threaded rod 2120, and one end of the first threaded rod 2120 is rotatably connected to the inner cavity of the adjusting plate 2117 through a bearing. By arranging the inclined plate 2116, the first threaded rod 2120, the adjusting plate 2117 and the adjusting groove 2119 for coordinated use, the position of the adjusting plate 2117 can be adjusted by rotating the first threaded rod 2120, so that plates of different sizes can be pushed, and the adjusting plate 2117 can be guided by the round rod 2118.

[0024] The two opposite sides of the two fixed plates 2101 are fixedly connected with a scale plate 2121, and one side of the upper plate 2102 is fixedly connected with an indicator needle 2122 used in conjunction with the scale plate 2121. By setting the scale plate 2121 and the indicator needle 2122 for use in conjunction with each other, when the two upper plates 2102 are moved to the opposite side, the upper plate 2102 will drive the indicator needle 2122 to move, and the indicator needle 2122 is used to indicate the scale plate 2121, thereby facilitating and quickly adjusting the position of the upper plate 2102, wherein the pressing plate 2107 and the top block 2110 are both detachable, so that the pressing plates 2107 and the top blocks 2110 of different sizes can be replaced.

[0025] The specific implementation of this embodiment is as follows: when bending the plate, the plate is moved between the upper plate 2102 and the lower plate 2103, and the fixed plate 2101 and the lower pressing plate 12 are driven downward by the hydraulic rod 13 to move the upper plate 2102 downward. When the upper plate 2102 moves downward, the connecting plate 2111 and the extrusion plate 2112 are driven downward to move. The extrusion plate 2112 moves downward to squeeze the push plate 2113, wherein the bottom of the push plate 2113 contacts the top of the lower plate 2103, thereby pushing the plate toward the middle through the push plate 2113, thereby achieving the effect of aligning the plate. After alignment, the upper plate 2102 continues to move downward, thereby driving the pressing plate 2107 to move downward. The plate is pressed down by the electric telescopic rod 2109 at this time, and the electric telescopic rod 2109 is started to drive the top block 2110 to move upward. Since the top block 2110 and the pressing plate 2107 are not on the same horizontal plane, the effect of bending both sides of the plate is achieved, wherein the bending angle of one side of the plate is adjusted by the distance that the top block 2110 moves upward, and the distance between the two lower plates 2103 can be adjusted by rotating the two-way threaded rod 2105. When the two lower plates 2103 move to the opposite side, the upper plate 2102 will move synchronously with the lower plate 2103 under the action of the first telescopic rod 2104. The position of the upper plate 2102 can be adjusted according to the indicator needle 2122 and the scale plate 2121, so that TV shells of different sizes can be bent.

[0026] Example 2: Please refer to Figure 1-Figure 14 The present invention provides a technical solution: a bending device based on the production of television shells, and the present invention makes corresponding improvements to the technical problems mentioned in the background technology.

A fixed groove 2206 is opened on the inner wall of the mounting groove 2201, and a fixed rod 2207 is slidably connected to the inner cavity of the fixed groove 2206, and the top of the fixed rod 2207 is connected to the concave plate 22 02, one end of the fixing rod 2207 is fixedly connected to the second spring 2208, one end of the second spring 2208 is fixedly connected to the inner wall of the fixing groove 2206, and the conveying unit 22 is set to place the plate on the top of the transmission belt 2204 so that the plate is located between the two adjustment plates 2117, and then the motor 2205 is started by the external control switch, so that the motor 2205 drives the transmission shaft 2203 to rotate, thereby achieving the effect of conveying the plate, and the elastic coefficient of the second spring 2208 is sufficient to support the top of the transmission belt 2204 to be higher than the top of the lower plate 2103. When the upper plate 2102 moves downward, it will drive the pressing plate 2107 to press down the concave plate 2202, and the structural design of the conveying unit 22 will not affect the bending of the plate.

[0028] The specific implementation method of this embodiment is: place the plate on the top of the transmission belt 2204 so that the plate is located between the two adjustment plates 2117, and then use the external control switch to start the motor 2205, so that the motor 2205 drives the transmission shaft 2203 to rotate, thereby achieving the effect of conveying the plate, and the elastic coefficient of the second spring 2208 is sufficient to support the top of the transmission belt 2204 higher than the top of the lower plate 2103.

[0029] Example 3: Please refer to Figure 1-Figure 14 The present invention provides a technical solution: a bending device based on the production of television shells, and the present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0030] The flip mechanism 3 includes a rotating column 301 rotatably connected to the top of the operating table 1, the top of the rotating column 301 is fixedly connected to a connecting frame 302, the surface of the connecting frame 302 is fixedly connected to a connecting pipe 303, the top of the connecting pipe 303 is fixedly connected to a circular plate 304, the top of the circular plate 304 is fixedly connected to a suction cup 305, the surface of the connecting pipe 303 is rotatably connected to a ring 306, the surface of the ring 306 is rotatably connected to the surface of the connecting pipe 303, one end of the rotating column 301 is rotatably connected to a gear 307 through a one-way bearing, the inner cavity of the operating table 1 is slidably connected to a toothed plate 308 used in conjunction with the gear 307, the bottom of the lower pressure plate 12 is fixedly connected to a moving rod 309 used in conjunction with the toothed plate 308, one end of the toothed plate 308 is inclined, Figure 8 As shown, the tooth plate 308 is composed of three parts, a tooth plate section, a cylindrical section and an inclined block section. By setting a flip mechanism 3, when the lower pressure plate 12 moves downward, it will drive the moving rod 309 to move downward, so that the moving rod 309 squeezes the inclined block section of the tooth plate 308, so that the tooth plate 308 drives the gear 307 to rotate, and when the gear 307 rotates, it will drive the rotating column 301 to rotate ninety degrees. When the moving rod 309 stops squeezing the tooth plate 308, the tooth plate 308 moves in the opposite direction, so that the gear 307 rotates in the opposite direction. Under the action of the one-way bearing, the rotating column 301 will not rotate in the opposite direction, and the pressing plate 2107 first presses down the concave plate 2202. When it is pressed down a certain distance, the plate will contact the top of the suction cup 305. When it continues to move downward, the moving rod 309 will squeeze the tooth plate 308, thereby completing the operation of rotating the plate ninety degrees.

[0031] A third spring 310 is provided on the movable sleeve on the surface of the tooth plate 308, one end of the third spring 310 is fixedly connected to the tooth plate 308, and the other end of the third spring 310 is fixedly connected to the inner wall of the operating table 1. By providing the third spring 310, when the moving rod 309 squeezes the tooth plate 308, the third spring 310 will be deformed by force. When the moving rod 309 stops squeezing the tooth plate 308, the third spring 310 is used to reset the tooth plate 308.

[0032] One side of the ring 306 is fixedly connected with a fixed pipe 311, one side of the support platform 11 is fixedly connected with a fixed shell 312, the inner cavity of the fixed shell 312 is slidably connected with a piston 313, the bottom of the piston 313 is fixedly connected with a linkage rod 314, one end of the linkage rod 314 is fixedly connected to one side of the moving rod 309, and one end of the fixed pipe 311 is fixedly connected to the top of the fixed shell 312. By setting the fixed pipe 311, the fixed shell 312, the piston 313 and the linkage rod 314 for use, when the lower pressure plate 12 moves downward, The linkage rod 314 is driven to move downward, so that the piston 313 moves in the inner cavity of the fixed shell 312, so that the air is sucked from the suction cup 305 to the circular plate 304, the connecting tube 303, the ring 306, the fixed tube 311 and the inner cavity of the fixed shell 312 in sequence. When the plate is located on the top of the suction cup 305, the plate can be sucked by the suction cup 305, thereby increasing the stability of the plate. The ring 306 adopts conventional means to form a seal with the connecting tube 303 and the rotating shaft respectively. This is the prior art and will not be elaborated on in detail.

[0033] Four limit rods 315 are fixedly connected to the top of the operating table 1, and four rubber blocks 316 are fixedly connected to the surface of the rotating column 301. A limit groove 317 for use with the rubber block 316 is opened on one side of the limit rod 315. By setting the rubber block 316, the limit rod 315 and the limit groove 317 for use together, the four limit rods 315 are arranged in a ring shape. When the rotating column 301 rotates ninety degrees, the rubber block 316 will be driven to get stuck in the inner cavity of the limit groove 317 to prevent the rotating column 301 from rotating when the gear 307 rotates in the opposite direction.

[0034] The specific implementation of this embodiment is as follows: when the lower pressing plate 12 moves downward, it will drive the moving rod 309 to move downward, so that the moving rod 309 squeezes the inclined block section of the tooth plate 308, so that the tooth plate 308 drives the gear 307 to rotate, and when the gear 307 rotates, it will drive the rotating column 301 to rotate ninety degrees. When the moving rod 309 stops squeezing the tooth plate 308, the tooth plate 308 moves in the opposite direction, so that the gear 307 rotates in the opposite direction. Under the action of the one-way bearing, the rotating column 301 will not rotate in the opposite direction, and in the process of the pressing plate 2107 moving downward, the pressing plate 2107 first presses down the concave plate 2202 When pressed down a certain distance, the plate will contact the top of the suction cup 305. When it continues to move downward, the moving rod 309 will squeeze the tooth plate 308, thereby completing the operation of rotating the plate ninety degrees. When the lower pressure plate 12 moves downward, it will drive the linkage rod 314 to move downward, so that the piston 313 moves in the inner cavity of the fixed shell 312, so that the air is sucked from the suction cup 305 to the circular plate 304, the connecting tube 303, the ring 306, the fixed tube 311 and the inner cavity of the fixed shell 312 in turn. When the plate is located at the top of the suction cup 305, the plate can be sucked by the suction cup 305, thereby increasing the stability of the plate.
