[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5. A sheet metal support device for a bending machine includes a bending machine body 1. The outer wall of the bending machine body 1 is provided with a mounting base 2. A motor 3 is fixedly mounted on the outer wall of the mounting base 2. A slide groove 5 is opened on the outer wall of the mounting base 2. A double-ended lead screw 4 is fixedly sleeved on the outer edge of the output shaft of the motor 3. A slider 8 is threadedly connected to the outer wall of the double-ended lead screw 4. A body 6 is fixedly mounted on the outer wall of the slider 8. A universal wheel 7 is provided at the bottom of the body 6. A flip plate 9 is rotatably connected to the inner wall of the body 6. A slide groove 10 and a slide groove 11 are respectively opened on the outer wall of the flip plate 9. A steering component 12 is provided on the inner wall of the body 6. A positioning component 13 is provided on the outer wall of the flip plate 9.

[0026] The steering assembly 12 includes a storage box 121, a guide column 122 is fixedly installed on the inner wall of the storage box 121, a motor 123 is fixedly installed on the outer wall of the body 6, a threaded rod 124 is fixedly sleeved on the outer edge of the output shaft of the motor 123, a sleeve 125 is threadedly connected to the outer wall of the threaded rod 124, and a connecting rod 126 is provided on the outer wall of the sleeve 125.

[0027] In the above structure, by setting the flip plate 9, when the bending machine body 1 performs a V-shaped bend on one end of the sheet metal, the flip plate 9 will cause the sheet metal to flip to a 45-degree angle, thereby completing the first bend. At the same time, when a U-shaped bend is required, through the cooperation of the steering component 12 and the positioning component 13, the flip plate 9 will slowly slide when the bending machine body 1 continuously presses the sheet metal, thereby causing the sheet metal to be continuously bent into a U-shape, thus completing the second bend.

[0028] In a preferred embodiment: the positioning component 13 includes a cylinder 131, the telescopic end of the cylinder 131 is fixedly fitted with a placement plate 132, the outer wall of the placement plate 132 is fixedly fitted with an electromagnet 133 and a brush head 134, the outer wall of the flip plate 9 is fixedly installed with a motor 135, the outer edge of the output shaft of the motor 135 is fixedly sleeved with a double-ended lead screw 136, and the outer wall of the double-ended lead screw 136 is threadedly connected with a positioning block 137.

[0029] In a preferred embodiment: the bottom shape of the placement plate 132 is the same as the inner wall shape of the slide groove 2 10, and the bottom of the placement plate 132 is slidably fitted to the inner wall of the slide groove 2 10. There are two positioning blocks 137, and the two positioning blocks 137 are respectively arranged opposite to each other on both sides of the outer wall of the double-ended screw 2 136. The outer wall of the two double-ended screw 2 136 is the same as the inner wall shape of the slide groove 3 11, and the outer wall of the double-ended screw 2 136 is slidably fitted to the inner wall of the slide groove 3 11.

[0030] In the above structure, by setting up the positioning block 137, electromagnet 133, and brush head 134, the plate is placed on the surface of the brush head 134. Then, by starting the motor 135, the double-headed lead screw 136 rotates along the outer edge of the output shaft of the motor 135, causing the positioning blocks 137, which are positioned opposite each other on the outer wall, to slide relative to each other along the inner wall of the slide groove 11. When the two positioning blocks 137 slide, they will center and position the plate on the surface of the brush head 134. After the plate is centered, the electromagnet 133 is energized by the external power supply. The top of the electromagnet 133 generates a certain magnetic force, causing the bottom of the plate to be attracted by the top of the electromagnet 133. Then, by rotating the motor 3135 in the opposite direction, the motor 3135 drives the double-headed lead screw 2136 and the positioning block 137 to move in opposite directions, so that the two positioning blocks 137 will disengage from the outer wall of the plate and reset, thus completing the pre-processing preparation of the plate. At the same time, when the plate needs to be bent into a U-shape in two stages, the cylinder 131 is activated, so that the extension end of the cylinder 131 will drive the placement plate 132 to slide along the inner wall of the slide groove 210. When the cylinder 131 slides, the plate on the top of the brush head 134 will also slide in the same way. When the bending machine body 1 is continuously stamped, the plate will be bent into a U-shape by the slow sliding of the plate, thus assisting the bending.

[0031] In a preferred embodiment: the outer wall of the slider 8 has the same shape as the inner wall of the groove 5, and the outer wall of the slider 8 is slidably fitted to the inner wall of the groove 5.

[0032] In the above structure, by setting the slider 8 and the slide groove 5, when the machine body 6 is adjusted, the machine body 6 will slide along the inner wall of the slide groove 5 via the slider 8, thereby realizing the adjustment of the plate with different widths.

[0033] In a preferred embodiment: the body 6, the universal wheel 7, the slider 8, the flip plate 9, the slide groove 10, the slide groove 11, the steering assembly 12 and the positioning assembly 13 are regarded as a movable assembly, and the movable assembly is respectively arranged in parallel on both sides of the outer wall of the double-ended lead screw 4.

[0034] In the above structure, by setting up the body 6, universal wheels 7, sliders 8, flip plates 9, slide rails 10 and 11, steering components 12 and positioning components 13, the body 6, with the cooperation of universal wheels 7 and sliders 8, moves its two sets of bodies 6 to a relatively suitable position for the plate. Then, when the plate on top of the body 6 is bent, the steering components 12 and positioning components 13 cooperate to assist in bending the plate. Thus, with the synchronous cooperation of the two sets of moving components, the plate is more stable when assisting the bending of the plate.

[0035] In a preferred embodiment: the inner wall of the sleeve 125 has the same shape as the outer wall of the guide post 122, and the inner wall of the sleeve 125 and the outer wall of the guide post 122 are slidably fitted together.

[0036] In the above structure, by setting the sleeve 125 and the guide post 122, the threaded rod 124 is driven by the outer edge of the output shaft of the motor 123 to rotate, so that the rotating threaded rod 124 will drive the sleeve 125 to slide linearly along the inner wall of the guide post 122.

[0037] In a preferred embodiment: there are two connecting rods 126, and the two connecting rods 126 are rotatably connected to the outer wall of the sleeve 125, and the ends of the two connecting rods 126 away from the sleeve 125 are rotatably connected to the bottom of the flap 9;

[0038] In the above structure, by setting up the sleeve 125, the connecting rod 126 and the flap 9, when the sleeve 125 slides, one end of the connecting rod 126 on both sides of its outer wall will push the flap 9 connected to the other end, so that the flap 9 will rotate under the push of the connecting rod 126. When the plate is bent into a V shape, the flap 9 will rotate at a 45-degree angle, and when it is bent into a U shape, the flap 9 will rotate to a maximum angle of 90 degrees, thereby realizing two bending assistance for the plate.

[0039] Working principle: When using this equipment, the plate is placed on the surface of the brush head 134. Then, by starting the motor 135, the double-headed screw 136 rotates along the outer edge of the output shaft of the motor 135, causing the positioning blocks 137 on both sides of the outer wall to slide relative to each other along the inner wall of the slide groove 11. When the two positioning blocks 137 slide, they will center and position the plate on the surface of the brush head 134. After the plate is centered, the electromagnet 133 is energized by the external power supply. The top of the electromagnet 133 will generate a certain magnetic force, and the bottom of the plate will be attracted by the top of the electromagnet 133. Then, by rotating the motor 135 in the opposite direction, the motor 135 will drive the double-headed screw 136 and the positioning blocks 137 to move in opposite directions, so that the two positioning blocks 137 will disengage from the outer wall of the plate and reset, thus completing the pre-preparation for bending the plate.

[0040] Then, by starting the bending machine body 1, the bending machine body 1 bends the reserved end of the plate. When the plate is bent into a V shape, the motor 123 is started, causing the threaded rod 124 to rotate under the drive of the output shaft of the guide column 122. The sleeve 125 slides along the outer wall of the guide column 122 under the rotation of the threaded rod 124. The two connecting rods 126 push the flip plate 9 upward under the sliding of the sleeve 125, causing the flip plate 9 to rotate to 45 degrees, thus completing the assistance in bending the plate into a V shape.

[0041] Simultaneously, when the sheet metal needs to be U-shaped bent, the flip plate 9 is in a 45-degree state, and the sleeve 125 slides, so that the connecting rod 126 will also drive the flip plate 9 to continue to rotate, so that the flip plate 9 will drive the sheet metal to rotate to 90 degrees. At the same time, when the flip plate 9 is rotated to 90 degrees, the cylinder 131 is activated, so that the extension end of the cylinder 131 drives the placement plate 132 to slide along the direction of the slide groove 10. The sliding placement plate 132 will drive the sheet metal placed on top to move slowly, so that when the bending machine body 1 continuously bends the sheet metal, the bending angle of the sheet metal will be U-shaped, thus completing the assistance in the U-shaped bending of the sheet metal.

[0042] 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 variations 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.
