[0025] In order to make the utility model purposes, technical scheme and advantages more clearly, the following will be further described in detail with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0026] Referring to Figures 1-5 A cold-rolled plate metal part automatic bending machine, including frame body 1, the inner side of frame body 1 is slidably connected with bending plate 4, and frame body 1 is provided with bending groove 5 at the bottom position close to bending plate 4, the top of frame body 1 is fixedly connected with top plate 2, and the top side of top plate 2 is fixedly connected with hydraulic oil cylinder 3 through bolts, and the output shaft of hydraulic oil cylinder 3 is fixedly connected between the top of top plate 2 and bending plate 4;

[0027] One side of frame body 1 is fixedly connected with side frame 8, and one side of side frame 8 is fixedly connected with driving motor 17 through bolts, and the inner side of side frame 8 is rotatably connected with bidirectional screw rod 9, one end of bidirectional screw rod 9 is rotatably connected between the side wall of side frame 8 and the output shaft of driving motor 17, and the two ends of bidirectional screw rod 9 are rotatably connected with nut block 10 through thread engagement, and one side of the two nut blocks 10 is fixedly connected with clamping plate 15, and the opposite side of the two clamping plates 15 is rotatably connected with a plurality of rollers 16, and push plate 13 is arranged between the two clamping plates 15, and the outer wall of side frame 8 is fixedly connected with air cylinder 14 through bolts, and the output shaft of air cylinder 14 is fixedly connected between the outer wall of side frame 8 and one side of push plate 13.

[0028] Further, one end of bidirectional screw rod 9 is rotatably connected between the inner wall of side frame 8 and the shaft, and the other end of bidirectional screw rod 9 is rotatably connected between the side wall of side frame 8 and the bearing sleeve, and bidirectional screw rod 9 can stably rotate under the drive of driving motor 17, and the other end of bidirectional screw rod 9 is stably connected with the side wall of side frame 8 through the bearing sleeve, which ensures the stability and accuracy during rotation, and improves the operation stability and bending accuracy of the equipment.

[0029] Further, one side of the two nut blocks 10 is fixedly connected with sliding block 11, and the two sliding blocks 11 are slidably connected between the side wall of side frame 8 and sliding groove 12, when bidirectional screw rod 9 rotates, nut block 10 can drive sliding block 11 to slide stably in sliding groove 12, so as to ensure the straightness and synchronism of the two clamping plates 15 when they approach or move away from each other, and improve the clamping stability and bending consistency.

[0030] Further, all rollers 16 are rotatably connected with one side of the two clamping plates 15 through shafts respectively, rollers 16 reduce the frictional resistance between clamping plate 15 and metal part material plate, avoid scratching the surface of the material, and facilitate the movement of push plate 13, which protects the surface of the material and improves the operation convenience.

[0031] Further, the two sides of the bending plate 4 are fixedly connected with the sliding blocks 6, and the two sliding blocks 6 are slidably connected between the inner wall of the frame body 1 and the sliding grooves 7. The bending plate 4 can stably slide along the sliding grooves 7 under the pushing of the hydraulic oil cylinder 3, ensuring the straightness and precision during the bending process. Meanwhile, the sliding connection between the sliding blocks 6 and the sliding grooves 7 reduces the frictional resistance during the movement, improving the bending precision and the service life of the equipment.

[0032] Further, the connection between the output shaft of the hydraulic oil cylinder 3 and the top plate 2 is a sliding connection, and the connection between the output shaft of the air cylinder 14 and the side frame 8 is also a sliding connection. This sliding connection mode can ensure that the output shafts of the hydraulic oil cylinder 3 and the air cylinder 14 move more flexibly and smoothly, reducing the resistance and wear caused by the friction at the connection, improving the operation efficiency of the equipment and reducing the maintenance cost.

[0033] Further, the gap between the two sliding blocks 6 and the two sliding grooves 7 is matched. This gap matching mode can ensure that the bending plate 4 will not be stuck or deviate from the track due to excessive frictional resistance during the sliding process. Meanwhile, it is also convenient to clean and maintain the sliding blocks 6 and the sliding grooves 7, improving the operation stability and maintenance convenience of the equipment.

[0034] Further, the bottom of the push plate 13 is attached to the inner bottom of the frame body 1.

[0035] In summary:

[0036] Firstly, the operator places the sheet metal material to be bent between the two clamping plates 15 in the frame 1, and ensures that the material plate is tightly attached to one side of the push plate 13. In this step, the bottom of the push plate 13 is attached to the inner bottom of the frame 1, ensuring the stability and accuracy of the material plate when placed. Then, start the drive motor 17 on the side frame 8, the motor drives the bidirectional screw 9 to rotate stably. One end of the bidirectional screw 9 is connected to the inner wall of the side frame 8 through the shaft, and the other end is connected to the side wall of the side frame 8 through the bearing sleeve. This structure ensures the stability and accuracy of the bidirectional screw 9 during rotation, thereby improving the stability of the equipment operation. With the rotation of the bidirectional screw 9, the two nut seats 10 move towards the middle of the bidirectional screw 9 due to the threaded connection with the bidirectional screw 9. The movement of the nut seat 10 is realized by the smooth sliding of the sliding block 11 in the sliding groove 12, which ensures the straightness and synchronization of the two clamping plates 15 when they move closer or farther away, thereby improving the stability of clamping and the consistency of bending. After the two clamping plates 15 tightly clamp the sheet metal material, the rollers 16 on the clamping plates 15 come into contact with the material plate. Since all the rollers 16 are connected to the clamping plates 15 through the shaft, they can rotate freely with the movement of the clamping plates 15, thereby reducing the frictional resistance between the clamping plates 15 and the material plate and avoiding scratching the material surface. At the same time, this design also facilitates the movement of the push plate 13 to the bending area under the push of the air cylinder 14. Next, the air cylinder 14 is started, which pushes the push plate 13 to move the sheet metal material to the bending area until the desired bending position of the material is located at the bottom of the bending plate 4. During this process, the push plate 13 is attached to the inner bottom of the frame 1, ensuring the stability and accuracy of the material movement. Then, adjust the working pressure and stroke of the hydraulic cylinder 3 according to the bending requirements. The output shaft of the hydraulic cylinder 3 is connected to the top plate 2 through a sliding connection, which makes the hydraulic cylinder 3 more flexible and smooth during movement, reducing the resistance and wear caused by friction at the connection. After starting the hydraulic cylinder 3, its output shaft moves downward, driving the bending plate 4 to move downward through the top plate 2. The two sides of the bending plate 4 are connected to the inner wall of the frame 1 through the sliding block 6 and the sliding groove 7, which ensures the straightness and precision of the bending plate 4 during downward movement. At the same time, the gap between the sliding block 6 and the sliding groove 7 reduces the frictional resistance during movement, improving the bending precision and service life of the equipment. Finally, the bottom of the bending plate 4 is pressed into the bending groove 5 at the bottom of the frame 1, completing the bending operation of the sheet metal material. During the entire bending process, the precise fit and stable connection between the components ensure the accuracy and efficiency of the bending.
