[0002] The molds in traditional bending machines are usually specially designed for specific bending angles, which means that when the plate needs to be bent at different angles, different molds often need to be replaced. Replacing molds will take a lot of time, which not only reduces production efficiency but also increases labor costs.

[0003] Therefore, it is necessary to develop a new type of bending machine that can overcome the above-mentioned shortcomings of traditional bending machines to meet the needs of bending at multiple different angles during the plate bending process. Utility Model Content

When a plate is bent at different angles, there is no need to replace the entire die as in a traditional bending machine. Instead, the plate only needs to be aligned with the lower cutting die with the grooves of the corresponding bending angle, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A multi-angle bending bending machine includes a workbench, on the surface of which a lower cutting die and a fixed plate are detachably mounted via a slide groove.

[0021] To solve the technical problem of how to bend the plate at multiple angles, please refer to Figure 1-Figure 4 , this embodiment provides the following technical solutions:

[0022] A multi-angle bending bending machine includes a workbench 1, on the surface of which a lower cutting die 2 and a fixed plate 3 are detachably mounted via a slide groove 11. There are multiple lower cutting dies 2, and the upper surface of each lower cutting die 2 is provided with grooves of different bending angles.

[0023] The upper end of each lower cutting die 2 is equipped with a bending assembly 4, which includes a hydraulic cylinder 41. The output end of the hydraulic cylinder 41 is fixedly connected to a knife seat 42. An upper cutting die 43 is detachably installed in the knife seat 42. The upper cutting die 43 is adapted to the lower cutting die 2 at its lower end.

[0024] The knife seat 42 is fixed to the upper knife die 43 by bolts, and a guide rod 44 is installed on the top of the knife seat 42. There are two guide rods 44, which are symmetrically arranged with respect to the hydraulic cylinder 41.

[0025] Specifically, according to the required bending angle, a lower cutting die 2 with a groove corresponding to the bending angle is selected from multiple lower cutting dies 2, and the plate to be bent is accurately placed on the selected lower cutting die 2 so that the portion of the plate to be bent is aligned with the groove on the lower cutting die 2. The hydraulic cylinder 41 at the upper end of the lower cutting die 2 is started, and the hydraulic cylinder 41 drives the upper cutting die 43 adapted thereto to move downward, and the guide rod 44 is used to guide the cutter holder 42 to move vertically downward, thereby preventing the cutter holder 42 from deflecting during the movement.

[0026] As the knife seat 42 moves downward, the upper knife die 43 gradually approaches the lower knife die 2. When the upper knife die 43 contacts the lower knife die 2 and applies pressure to the plate, since there is a groove with a specific bending angle on the lower knife die 2, under the joint action of the upper and lower molds, the plate begins to bend according to the angle of the groove of the lower knife die 2 until the plate reaches the required bending degree.

[0027] To solve the technical problem of how to install the lower die, please refer to Figure 2-Figure 3 , this embodiment provides the following technical solutions:

[0028] The two adjacent lower cutting dies 2 are connected by positioning rods 6 and positioning holes 7. The fixed plate 3 is arranged at the outermost end of all the lower cutting dies 2 and is fixedly connected to the workbench 1 by bolts. The positioning rod 6 is welded on the surface of the fixed plate 3. The bottom of the lower cutting die 2 and the fixed plate 3 are welded with sliders 5 that are compatible with the slide groove 11. The side end of the workbench 1 that fits with the lower cutting die 2 is provided with a positioning hole 7.

[0029] The front and rear ends of the two adjacent lower cutting dies 2 are connected by a reinforcement block 9. The reinforcement block 9 is L-shaped, and its horizontal end is fixedly connected to the workbench 1 by bolts, and its vertical end is fixedly connected to the lower cutting die 2 by bolts. A connecting hole 8 that is compatible with the reinforcement block 9 is opened at the side end of the lower cutting die 2.

[0030] Specifically, the first lower cutting die 2 is inserted into the slide groove 11 on the surface of the workbench 1 through the slider 5, and then the lower cutting die 2 is slid along the slide groove 11 to the side end of the workbench 1 until its positioning rod 6 is plugged into the positioning hole 7 on the side end of the workbench 1;

[0031] Then, insert the subsequent lower cutting dies 2 into the slide groove 11 in sequence, and make the positioning rod 6 on the new lower cutting die 2 accurately plug into the positioning hole 7 on the adjacent lower cutting die 2, until all the lower cutting dies 2 are installed, then insert the fixing plate 3 into the slide groove 11 through the slider 5, and move the fixing plate 3 until the positioning rod 6 on the fixing plate 3 is inserted into the positioning hole 7 on the surface of the adjacent lower cutting die 2, and use bolts to fix the fixing plate 3 to the workbench 1;

[0032] Finally, install the reinforcement block 9 at the front and rear ends of the joints of the two adjacent lower cutting dies 2, align the vertical end of the reinforcement block 9 with the connection hole 8 opened at the side end of the lower cutting die 2, use bolts to fix the vertical end of the reinforcement block 9 to the lower cutting die 2, and then use bolts to fix the horizontal end of the reinforcement block 9 to the workbench 1 to further enhance the connection stability between adjacent lower cutting dies 2.
