Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0031] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-4 An automatic bending machine that facilitates loading and unloading, comprising a small bending machine body 1;

[0032] The small bending machine body 1 is equipped with a convenient bending and unloading mechanism 2 for convenient unloading of the workpiece after closed bending;

[0033] The small bending machine body 1 is equipped with a workpiece positioning mechanism 3 for positioning the workpiece on both sides;

[0034] like Figure 2As shown, the convenient bending and unloading mechanism 2 includes a bending component 21, an unloading opening and closing component 22, a pushing component 23, and a linkage component 24; the small bending machine body 1, the unloading opening and closing component 22, the pushing component 23, and the linkage component 24 are all connected to the bending component 21; the unloading opening and closing component 22 is connected to the linkage component 24; the pushing component 23 is connected to the linkage component 24; the bending component 21 is used to bend the workpiece, the unloading opening and closing component 22 is used to control the opening and closing of the closed bending workpiece unloading port; the pushing component 23 is used to push the closed bending workpiece unloading; the linkage component 24 is used to link the unloading opening and closing component 22 and the pushing component 23.

[0035] In this invention, the operator places the workpiece on the bending assembly 21, and the workpiece positioning mechanism 3 drives the workpiece to be clamped and positioned on both sides. Then, the small bending machine body 1 drives the bending assembly 21 to bend the workpiece. After bending, the operator pushes the closed bent workpiece through the pusher assembly 23. At the same time, the pusher assembly 23 is linked with the unloading opening and closing assembly 22 through the linkage assembly 24, so that the unloading port opens synchronously. Then, the workpiece is guided by the pusher assembly 23 to avoid the obstruction of the workpiece positioning mechanism 3, and then the workpiece is pushed out of the bending assembly 21. This achieves convenient unloading of the closed bent workpiece, prevents workpiece rotation and deviation, and improves workpiece accuracy.

[0036] The bending assembly 21 includes an upper die cutter 211, a lower die cutter 212, and a connecting frame 213; the upper end of the connecting frame 213 is fixedly connected to the drive end of the small bending machine body 1, the lower end of the connecting frame 213 is fixedly connected to the upper die cutter 211, and the lower end of the lower die cutter 212 is fixedly connected to the inner bottom surface of the small bending machine body 1; the feeding opening and closing assembly 22, the pushing assembly 23, and the linkage assembly 24 are all connected to the connecting frame 213;

[0037] The feeding opening and closing assembly 22 includes a sliding block 221; a sliding groove 222 is provided at the right end of the connecting frame 213; the sliding block 221 is slidably connected to the connecting frame 213 through the sliding groove 222; the sliding block 221 is connected to the linkage assembly 24;

[0038] The material pushing assembly 23 includes a sliding push block 231, a locking block 232, and a guide plate 234; the sliding push block 231 is slidably connected to the upper die cutter 211 through a limiting groove on the upper die cutter 211; a locking groove 233 is provided at the left end of the connecting frame 213; the locking block 232 is engaged with the connecting frame 213 through the locking groove 233; the locking block 232 is slidably connected to the sliding push block 231 through a limiting groove on the sliding push block 231, and a pull rod 235 is fixedly installed at the front end of the locking block 232; the guide plate 234 is connected to the linkage assembly 24; the sliding push block 231 is connected to the linkage assembly 24.

[0039] The linkage component 24 includes an L-shaped plate 241, a sliding pin 242, and a stop block 244; two L-shaped plates 241 are symmetrically arranged on the front and rear sides of the connecting frame 213; the L-shaped plates 241 are rotatably connected to the connecting frame 213 through a rotating shaft and a bearing; the sliding pin 242 is fixedly installed on the front and rear sides of the upper end of the sliding block 221, and a sliding groove 243 is opened on the right end of the L-shaped plate 241, the sliding pin 242 is slidably connected to the sliding groove 243, and the stop block 244 is fixedly installed on the right end of the sliding push block 231; the guide plate 234 is fixedly installed on the front end of the stop block 244; the lower end of the L-shaped plate 241 is slidably connected to the upper end of the sliding push block 231;

[0040] In this invention, the operator places the workpiece to be processed between the upper die cutter 211 and the lower die cutter 212. Then, the small bending machine body 1 drives the lower die cutter 212 to press down through the connecting frame 213 to perform a closed bending of the workpiece. When the closed bending is completed and the workpiece needs to be unloaded, the operator pulls the pull rod 235 upward to cause the locking block 232 to slide upward, thereby releasing the limiting position between the locking block 232 and the locking groove 233. Then, the operator moves the sliding push block 231 to the right. As the sliding push block 231 slides to the right, the sliding push... The upper end of block 231 drives the L-shaped plate 241 and the connecting frame 213 to rotate. The rotation of the L-shaped plate 241 drives the sliding pin 242 to slide within the sliding groove 243. At the same time, the sliding block 221 is driven to slide upward by the sliding pin 242. At this time, the unloading point opens. Then, because of the slope of the guide plate 234, which is wider at the back and narrower at the front, when the guide plate 234 pushes the workpiece to the right, it will guide the workpiece to slide to the right and move forward along the slope until the workpiece is pushed to complete the unloading. This realizes convenient unloading of closed bending workpieces.

[0041] like Figure 2 and Figure 3 As shown, the workpiece positioning mechanism 3 includes a drive assembly 31, a clamping and positioning assembly 32, and a limiting assembly 33. The drive assembly 31 is connected to the small bending machine body 1. Both the drive assembly 31 and the limiting assembly 33 are connected to the clamping and positioning assembly 32. The two sets of clamping and positioning assemblies 32 are symmetrically arranged front and back. The two sets of limiting assemblies 33 are symmetrically arranged front and back. The limiting assembly 33 is connected to the small bending machine body 1. The limiting assembly 33 is connected to the drive assembly 31. The drive assembly 31 is used to drive the clamping and positioning assembly 32. The clamping and positioning assembly 32 is used to clamp and fix the left and right sides of the closed bending workpiece. The limiting assembly 33 is used to limit the sliding of the clamping and positioning assembly 32.

[0042] The drive assembly 31 includes a cylinder 311 and a horizontal plate 312; the upper end of the cylinder 311 is fixedly connected to the inner top of the small bending machine body 1, and the drive end of the cylinder 311 is fixedly connected to the upper end of the horizontal plate 312; the horizontal plate 312 is connected to the clamping and positioning assembly 32.

[0043] The clamping and positioning assembly 32 includes a connecting rod 321 and a clamping plate 322; the upper end of the connecting rod 321 is hinged to the horizontal plate 312; the lower end of the connecting rod 321 is hinged to the clamping plate 322; and the lower end of the clamping plate 322 is connected to the limiting assembly 33.

[0044] The limiting component 33 includes a slide rail 331, a slider 332, and a limiting slide rod 333; the lower end of the slide rail 331 is fixedly connected to the inner bottom surface of the small bending machine body 1; the slide rail 331 and the slider 332 are slidably connected; the upper end of the slider 332 is fixedly connected to the clamping plate 322; the upper end of the limiting slide rod 333 is fixedly connected to the inner top surface of the small bending machine body 1; and the limiting slide rod 333 is slidably connected to the horizontal plate 312.

[0045] In this utility model, the operator places the workpiece to be processed between the upper die cutter 211 and the lower die cutter 212. Then, the cylinder 311 is activated to push the horizontal plate 312 to slide downward along the limiting slide bar 333. At the same time, the horizontal plate 312 drives the lower ends of the two connecting rods 321 to move closer to each other. The lower ends of the two slide rails 331 move closer to each other, causing the two clamping plates 322 to move closer to each other. The two clamping plates 322 drive the slider 332 to slide in a limited position with the slide rail 331. While the two clamping plates 322 move closer to each other, they clamp and fix the left and right sides of the workpiece to prevent the workpiece from shifting during bending and affecting the processing accuracy.
