Because the first threaded rod 5 is threadedly connected to the support column 3, and the bending block 4 is rotatably connected to the first threaded rod 5, the rotation of the first threaded rod 5 drives the bending block 4 to move up and down, so The bending block 4 is moved downward to bend the sheet metal placed on the placement plate 2, so that the bending of the sheet metal is not only more accurate but also more convenient, and a motor 12 is fixedly connected to one side of the outer wall of the placement plate 2 through a fixed block; a rotating shaft 13 is provided at the output end of the motor 12; the top of the outer wall of the support column 3 is rotatably connected to a rotating rod 14 through a second block; one end of the outer wall of the rotating rod 14 and the outer side wall of the rotating shaft 13 are fixedly connected to a first sprocket 15, and a pair of first sprockets 15 are connected by a chain 16; one end of the outer wall of the second bevel gear 7 is fixedly connected to the other end of the outer wall of the rotating rod 14; the inner side wall of the first bevel gear 6 is slidably connected to the outer side wall of the first threaded rod 5; the outer side wall of the first threaded rod 5 is provided with a sliding groove 17;The inner wall of the first bevel gear 6 is fixedly connected with a sliding block 18, and the outer wall of the sliding block 18 is slidably connected to the inner wall of the sliding groove 17; the bottom end of the outer wall of the first bevel gear 6 is provided with an annular groove 19; the inner wall of the annular groove 19 is slidably connected with a fixing rod 20, and the bottom end of the outer wall of the fixing rod 20 is fixedly connected to the top of the outer wall of the support column 3, and the first bevel gear 6 and the second bevel gear 7 are meshed with each other; the rotating shaft 13 is driven to rotate by the motor 12, because one end of the outer wall of the rotating rod 14 and the outer wall of the rotating shaft 13 are fixedly connected with a first sprocket 15, and a pair of first sprockets 15 are connected by a chain 16, so that the rotation of the rotating shaft 13 drives the rotating rod 14 to rotate through the pair of first sprockets 15 and the chain 16, so that the rotating rod 14 The rotation of the second bevel gear 7 drives the second bevel gear 7 to rotate. Since the second bevel gear 7 and the first bevel gear 6 are meshed with each other, the rotation of the second bevel gear 7 drives the first bevel gear 6 to rotate. Since the first bevel gear 6 is slidably connected to the first threaded rod 5, and the sliding block 18 on the first bevel gear 6 is slidably connected in the sliding groove 17 on the first threaded rod 5, the rotation of the first bevel gear 6 will drive the sliding block 18 to rotate, and the rotation of the sliding block 18 drives the first threaded rod 5 to rotate, and the first threaded rod 5 is slidably connected to the first bevel gear 6, so that when the first threaded rod 5 moves up and down due to rotation, it will not affect the first bevel gear 6 to drive the first threaded rod 5 to rotate, and the annular groove 19 on the first bevel gear 6 and the fixed rod 2 slidably connected in the annular groove 19 0, when the first threaded rod 5 is rotated, the fixing rod 20 will slide in the annular groove 19, so that the first bevel gear 6 is always located at one position for rotation, so that the first bevel gear 6 and the second bevel gear 7 are always meshed with each other, so that the rotation of the first threaded rod 5 can drive the bending block 4 to bend the sheet metal part, so that the device is simple and convenient to perform the bending process, and the third threaded rod 25 is rotatably connected to the top of the outer wall of the workbench 1; the outer wall of the third threaded rod 25 is threadedly connected to the adjusting plate 26, and the outer wall of the adjusting plate 26 is slidably connected to the inner wall of the support column 3, and the adjusting plate 26 matches the bending block 4. By rotating the third threaded rod 25, the third threaded rod 25 is threadedly connected to the adjusting plate 26. The rotation of the third threaded rod 25 can drive the adjustment plate 26 to move up and down. Since the adjustment plate 26 matches the bending block 4 and the outer wall of the adjustment plate 26 is slidably connected to the inner wall of the support column 3, the device can adjust the position of the adjustment plate 26 to determine the bending degree and the downward height of the bending block 4, so that the device can adjust the position of the adjustment plate 26 according to needs, so that the device can perform more types of bending processes, and a pair of sliding plates 21 symmetrical about the center line of the placement plate 2 are slidably connected through the top of the outer wall of the placement plate 2; the rotating shaft 13 is double-threaded, and one end of the outer wall of the rotating shaft 13 passes through the pair of sliding plates 21, and the rotating shaft 13 is threadedly connected to the pair of sliding plates 21;The outer wall of the pair of sliding plates 21 is fixedly connected with a clamping plate 22 on the opposite side through the first spring, and the outer wall bottom end of the pair of clamping plates 22 is slidably connected to the outer wall top end of the placing plate 2. When the motor 12 drives the rotating shaft 13 to rotate, so that the bending block 4 is bent, because the rotating shaft 13 is double-threaded, and one end of the outer wall of the rotating shaft 13 passes through the pair of sliding plates 21, the rotating shaft 13 is threadedly connected with the pair of sliding plates 21, so that the rotating shaft 13 rotates and drives the pair of sliding plates 21 to move toward the center or both sides at the same time, so that the pair of sliding plates 21 drives the pair of clamping plates 22 to move, so that the bending block 4 is bent. 4 has not yet encountered the sheet metal part, the clamping plate 22 will first encounter the sheet metal part, thereby clamping the sheet metal part. When the motor 12 continues to drive the rotating shaft 13 to rotate, so that the bending block 4 continues to move downward for bending, the sliding plate 21 will continue to move. At this time, the first spring will contract, so that the extrusion force of the first spring squeezes the sheet metal part through the clamping plate 22, making the sheet metal part more stable during the bending process and not easy to shift or move, so that when the sheet metal part is bent, it is not easy to have defects on the sheet metal part. When the bending block 4 completes the bending and moves upward, the pair of sliding plates 21 will also move to release the pair of clamping plates 22 from being fixed. , so that the fixing and releasing of the device does not require manual operation, making the fixing operation of the device more convenient, and a square plate 23 is fixedly connected to the top of the opposite side of the outer wall of a pair of clamping plates 22; the bottom ends of the outer walls of a pair of square plates 23 are fixedly connected to a pressing block 24 through a second spring, and the pressing block 24 is in a right-angled trapezoidal shape, and the pair of pressing blocks 24 are symmetrical about the center line of the placement plate 2, and the square plates 23 are fixedly connected to the top of the opposite side of the outer wall of a pair of clamping plates 22; the bottom ends of the outer walls of a pair of square plates 23 are fixedly connected to the pressing block 24 through a second spring, so that the pair of clamping plates 22 are simultaneously moved to the center When the center moves, the square plate 23 and the lower pressing block 24 will be driven to move. When the square plate 23 and the lower pressing block 24 encounter the sheet metal, because the lower pressing block 24 is in the shape of a right-angled trapezoid, the clamping plate 22 continues to move so that the inclined surface of the lower pressing block 24 encounters the sheet metal. When the lower pressing block 24 continues to be given a moving force, the inclined surface of the lower pressing block 24 will slowly move up until it moves above the sheet metal, so that the lower pressing block 24 squeezes the sheet metal from top to bottom, so that a pair of lower pressing blocks 24 squeeze the sheet metal from the top of both sides of the sheet metal, thereby cooperating with the placing plate 2 to fix the sheet metal for the second time, so that the sheet metal can be more stable during the bending process;
[0025] Working principle: by rotating the second threaded rod 8, since the second threaded rod 8 is threadedly connected to the first block, the rotation of the second threaded rod 8 can make the second threaded rod 8 move forward and backward, and since one end of the outer wall of the second threaded rod 8 is rotatably connected to a positioning plate 9, the movement of the second threaded rod 8 can adjust the position of the positioning plate 9, and a square groove 10 is opened at the top of the outer wall of the placement plate 2; the inner wall of the square groove 10 is fixedly connected with a ruler 11, so that the device can adjust the position of the positioning plate 9 according to the bending requirements of the sheet metal, so that there will be no deviation when the sheet metal is bent, thereby not only the sheet metal can be processed and formed in one time, reducing the secondary processing cost, but also making the sheet metal bending process more precise. After the position of the positioning plate 9 is adjusted, the sheet metal is placed on the placement plate 2, one end of the sheet metal is against the positioning plate 9, and at this time, the motor 12 drives the rotating shaft 13 to rotate.

Because the second bevel gear 7 and the first bevel gear 6 are meshed with each other, the rotation of the second bevel gear 7 drives the first bevel gear 6 to rotate. Because the first bevel gear 6 is slidably connected to the first threaded rod 5, and the sliding block 18 on the first bevel gear 6 is slidably connected to the sliding groove 17 on the first threaded rod 5, the rotation of the first bevel gear 6 will drive the sliding block 1 8 rotates, so that the rotation of the sliding block 18 drives the first threaded rod 5 to rotate, and the first threaded rod 5 is slidably connected with the first bevel gear 6, so that when the first threaded rod 5 moves up and down due to the rotation, it will not affect the first bevel gear 6 to drive the first threaded rod 5 to rotate, and through the annular groove 19 on the first bevel gear 6 and the fixed rod 20 slidably connected in the annular groove 19, when the first threaded rod 5 rotates, the fixed rod 20 will slide in the annular groove 19, so that the first bevel gear 6 is always located at one position for rotation, so that the first bevel gear 6 and the second bevel gear 7 are always meshed with each other, because the first threaded rod 5 is threadedly connected with the support column 3, and the bending block 4 is rotatably connected with the first threaded rod 5, the rotation of the first threaded rod 5 drives the bending block 4 to move up and down, so that the bending block 4 moves downward to bend the sheet metal placed on the placement plate 2, making the bending of the sheet metal not only more accurate but also more convenient. When the motor 12 drives the rotating shaft 13 to rotate to make the bending block 4 bend, because the rotating shaft 13 is double-threaded, and one end of the outer wall of the rotating shaft 13 passes through a pair of sliding plates 21, the rotating shaft 13 is threadedly connected with the pair of sliding plates 21, so that the rotating shaft 13 rotates while driving the pair of sliding plates 21 to move toward the center or both sides at the same time, so that the pair of sliding plates 21 drives the pair of clamping plates 22 to move, so that when the bending block 4 has not encountered the sheet metal, the clamping plates 22 will first encounter the sheet metal, thereby clamping the sheet metal. When the motor 12 continues to drive the rotating shaft 13 to rotate, so that the bending block 4 continues to move downward for bending,The sliding plate 21 will continue to move, and the first spring will contract at this time, so that the extrusion force of the first spring can squeeze the sheet metal part through the clamping plate 22, making the sheet metal part more stable during the bending process and not easy to shift or move, so that the sheet metal part is not easy to have defects when it is bent, and when the bending block 4 completes the bending and moves up, the pair of sliding plates 21 will also move to release the pair of clamping plates 22, so that the fixing and releasing of the device do not require manual operation, making the fixing operation of the device more convenient, and the square plate 23 is fixedly connected to the top of the opposite side of the outer wall of the pair of clamping plates 22; the lower end of the outer wall of the pair of square plates 23 is fixedly connected to the pressing block 24 through the second spring, so that when the pair of clamping plates 22 move toward the center at the same time, the square plate 23 and the pressing block 24 will be driven to move, and when the square plate 23 and the pressing block 24 encounter the sheet metal part, because the pressing block 24 is in the shape of a right-angled trapezoid, the clamping plate 22 continues to move, which will cause the pressing block When the inclined surface of the lower pressing block 24 encounters the sheet metal, when the moving force of the lower pressing block 24 continues to be applied, the inclined surface of the lower pressing block 24 will slowly move up until it moves above the sheet metal, so that the lower pressing block 24 squeezes the sheet metal from top to bottom, so that a pair of lower pressing blocks 24 squeeze the sheet metal at the top of both sides of the sheet metal, thereby cooperating with the placing plate 2 to fix the sheet metal for the second time, so that the sheet metal can be more stable during the bending process, and by rotating the third threaded rod 25, because the third threaded rod 25 is threadedly connected with the adjustment plate 26, the rotation of the third threaded rod 25 can drive the adjustment plate 26 to move up and down, because the adjustment plate 26 matches the bending block 4, and the outer wall of the adjustment plate 26 is slidably connected to the inner wall of the support column 3, the device can adjust the position of the adjustment plate 26 to determine the bending degree and the downward height of the bending block 4, so that the device can adjust the position of the adjustment plate 26 according to needs, so that the device can perform more types of bending processes.
