Technical Field

[0001] This utility model belongs to the field of excavator bucket steel plate processing technology, specifically a steel plate bending machine for excavator bucket production. Background Technology

[0002] A bucket is a bucket-shaped component used to excavate loose materials such as soil, sand, gravel, and construction waste. It is assembled from parts such as bucket steel plates or wall panels. The most important part is the bending of the bucket steel plates. Therefore, this paper applies for a steel plate bending machine for bucket production.

[0003] In the existing technology, the plate bending machine with announcement number CN216801211U has the effect of avoiding deviation during the bending process of the horizontal plate and improving the accuracy of workpiece bending. However, in use, the workpiece is often manually transported to the processing platform. Since the manual loading and unloading of workpieces is relatively frequent, it increases the workload and intensity of the operators. Moreover, since the bucket steel plate is relatively heavy, it increases the difficulty of transporting the workpiece.

[0004] Therefore, a steel plate bending machine for excavator bucket production is proposed to address the above problems. Utility Model Content

[0011] Preferably, the output end of the motor is splinedly connected to a first rotating rod, one end of which is fixedly mounted with a bidirectional threaded conveying rod through one side of the connecting plate, and the bidirectional threaded conveying rod is disposed in a circular hole. The surface of the bidirectional threaded conveying rod is threadedly connected to a threaded block through a threaded hole, and the threaded block is disposed in a groove.

[0012] Preferably, a clamping block is fixedly installed on one side of the threaded block, and a fixing block is connected to the surface of the clamping block inserted into the square groove. The clamping block is adapted to the square groove, and a bucket bending module is fixedly installed at the lower end of the fixing block, and the bucket bending module is adapted to the bucket bending groove.

[0015] The beneficial effects of this utility model are:

[0016] This invention uses a servo motor powered by an external power source to drive a second rotating rod to rotate, which in turn drives a rotating disk to rotate. The rotating disk then drives a clamping frame to rotate, and the rotation of the clamping frame adjusts the angle of the clamped bucket steel plate. This allows for the loading and unloading of the bucket steel plate, reducing the workload of personnel and improving the working efficiency of the device.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Specific implementation examples are given below. Example

[0033] Please see Figures 1 to 6 This utility model provides a steel plate bending machine for excavator bucket production, including a processing table 1 and multiple fixed rods 3. The upper end of the processing table 1 is sequentially fixedly installed with a support rod 2 and multiple fixed rods 3. A motor slot 4 is opened on the upper right side of the processing table 1. A horizontal plate 5 is fixedly installed on the upper end of the support rod 2. A bending mechanism 6 is connected to the lower side of the horizontal plate 5 by bolts.

[0034] The lower end of the bending mechanism 6 is provided with a disassembly mechanism 7, and there are four fixing rods 3. A bucket bending groove 8 is fixedly installed on one side of the fixing rod 3, and a clamping and unloading mechanism 9 is provided inside the motor groove 4.

[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bending mechanism 6 includes a threaded connecting plate 61. The lower end of the horizontal plate 5 is connected to the threaded connecting plate 61 by bolts. A protective frame 62 is fixedly installed on one side of the threaded connecting plate 61. Multiple multi-section hydraulic cylinders 63 are fixedly installed inside the protective frame 62. A disassembly mechanism 7 is installed at the lower end of the multi-section hydraulic cylinders 63.

[0036] In the existing technology, the bucket steel plate is placed directly above the bucket bending groove 8, and then the connecting plate 71 is moved by the extension and retraction of the multi-section hydraulic cylinder 63. The connecting plate 71 drives the bucket bending module 81 to press down, and then the bucket bending module 81 bends the bucket steel plate, thereby performing the bending and forming process of the bucket steel plate. Example

[0037] Based on Embodiment 1, a disassembly mechanism 7 is further disclosed.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the disassembly mechanism 7 includes a connecting plate 71. The lower end of the multi-section hydraulic cylinder 63 is fixedly mounted with the connecting plate 71. Two grooves 72 are opened at the lower end of the connecting plate 71. Circular holes are opened on both sides of the grooves 72. A motor 73 is fixedly mounted on one side of the connecting plate 71. The output end of the motor 73 is splinedly connected to a first rotating rod 74. One end of the first rotating rod 74 passes through one side of the connecting plate 71 and is fixedly mounted with a bidirectional threaded conveying rod 75. The bidirectional threaded conveying rod 75 is set in the circular hole. A threaded block 77 is threadedly connected to the surface of the bidirectional threaded conveying rod 75 through a threaded hole 76. The threaded block 77 is set in the groove 72. A clamping block 78 is fixedly mounted on one side of the threaded block 77. A fixing block 80 is connected to the surface of the clamping block 78 by inserting it into a square groove 79. The clamping block 78 is adapted to the square groove 79. A bucket bending module 81 is fixedly mounted at the lower end of the fixing block 80, and the bucket bending module 81 is adapted to the bucket bending groove 8.

[0039] In the prior art, the fixing block 80 is inserted into the groove 72, and then the first rotating rod 74 is driven to rotate by the external power supply of the motor 73. The first rotating rod 74 drives the bidirectional threaded conveying rod 75 to rotate, and then the bidirectional threaded conveying rod 75 rotates to drive the threaded block 77 to move. The movement of the threaded block 77 drives the clamping block 78 to move. Then the clamping block 78 moves into the square groove 79 to clamp and fix the fixing block 80. Conversely, the restriction on the fixing block 80 is released. This serves to replace and maintain the bucket bending module 81, improving the maintenance convenience of the device. Example

[0040] Based on Embodiment 1, a clamping and unloading mechanism 9 is further disclosed.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the clamping and unloading mechanism 9 includes a servo motor 91. The servo motor 91 is fixedly installed inside the motor slot 4. The output end of the servo motor 91 is splinedly connected to a second rotating rod 92. A rotating disk 93 is fixedly installed at one end of the second rotating rod 92. Multiple rollers are provided on the contact surface between the lower end of the rotating disk 93 and the processing table 1. A first hydraulic cylinder 94 is fixedly installed at the upper end of the rotating disk 93. A moving plate 95 is fixedly installed at one end of the first hydraulic cylinder 94. A clamping frame 96 is fixedly installed at the upper end of the moving plate 95. Two square holes 97 are opened on the front of the clamping frame 96. A second hydraulic cylinder 98 is provided inside the square holes 97. A clamping plate 99 is fixedly installed at one end of the second hydraulic cylinder 98. An anti-slip pad is provided on the back of the clamping plate 99.

[0042] In the existing technology, the second hydraulic cylinder 98 extends and retracts to move the clamping plate 99, clamping the bent bucket steel plate. Then, the first hydraulic cylinder 94 extends and retracts to move the moving plate 95, which in turn moves the clamping frame 96, allowing the height of the bucket steel plate inside the bucket bending groove 8 to be adjusted. When the appropriate height is reached, the servo motor 91, connected to an external power source, drives the second rotating rod 92 to rotate. The second rotating rod 92 then drives the rotating disk 93 to rotate, which in turn drives the clamping frame 96 to rotate. Subsequently, the rotation of the clamping frame 96 adjusts the angle of the clamped bucket steel plate, thus achieving the function of loading and unloading the bucket steel plate, reducing the workload of personnel and improving the working efficiency of the device.
