[0014] The following is combined with Figure 1-3This application is described in further detail.

[0015] The present application embodiment discloses a strip metal product bending device, referring to Figure 1-3, including a processing table 1 and a support frame 2, the four corners at the bottom of the processing table 1 are fixedly connected with legs 3, the four legs 3 can cooperate to support the processing table 1, and strip metal products can be placed on the processing table 1. Both sides of the processing table 1 are provided with mounting parts 4 for fixing the support frame 2, and the two mounting parts 4 are composed of a mounting block 41 and three first bolts 42. The two mounting blocks 41 are respectively located on both sides of the support frame 2, wherein the three first bolts 42 are threaded through one of the mounting blocks 41, and the other three first bolts 42 are threaded through the other mounting block 41, wherein the four first bolts 42 are threadedly connected to the support frame 2, and the other two first bolts 42 are threadedly connected to the processing table 1, so that the support frame 2 is fixedly mounted on the processing table 1. At one end of the workbench 1, a bending assembly 5 is arranged inside the support frame 2. The bending assembly 5 consists of a bending head 51 and two hydraulic cylinders 52. The bending head 51 is located inside the support frame 2. The three hydraulic cylinders 52 are all fixedly installed on the top of the support frame 2. The hydraulic rods of the three hydraulic cylinders 52 are all movable and penetrate the support frame 2. The ends of the hydraulic rods of the three hydraulic cylinders 52 are respectively fixedly connected to the two ends of the top of the bending head 51 and the middle of the top. The hydraulic cylinder 52 is connected to the external reversing valve through an oil pipeline. The external reversing valve is connected to the external oil pump in the external oil tank through an oil supply pipe. After the external reversing valve is opened and the external oil pump is started, the external oil pump draws the oil in the external oil tank and transports it to the external reversing valve through the oil supply pipe. The external reversing valve discharges the oil to the hydraulic cylinder 52 through the oil pipeline. In the embodiment, the hydraulic rods of the three hydraulic cylinders 52 are pushed by the oil pressure inside the three hydraulic cylinders 52 to drive the bending head 51 to move downward, thereby bending the strip metal product. The top of the processing table 1 is fixedly connected with three limit frames 61 in parallel, and three clamping holes are arranged in parallel in the middle of the top of the support frame 2. The insides of the three clamping holes are movably penetrated by clamping rods 62, and the inner bottom walls of the three clamping rods 62 are in contact with the bottom end of the processing table 1. One side of the three clamping rods 62 is fixedly connected with a resistance rod 63, and one end of the three resistance rods 63 is respectively in contact with one of the inner side walls of the three limit frames 61. One end of the top of the processing table 1 is fixedly connected with a support block 65, and a connecting rod 64 is movably penetrated inside the support block 65. The tops of the three clamping rods 62 are fixed to the bottom ends of the connecting rods 64 The three clamping rods 62 can connect a connecting rod 64 and three abutting rods 63. After the three clamping rods 62 clamp the processing table 1, the three abutting rods 63 can be respectively located inside the three limit frames 61, thereby abutting against the strip metal products placed in the three limit frames 61. At the same time, the three abutting rods 63 cooperate with the three limit frames 61 to limit the three strip metal products to prevent them from tilting or shifting when being bent. A plug 66 is movably passed through one side of the support block 65. The plug 66 movably passes through one end of the connecting rod 64 to fix the connecting rod 64 and indirectly fix the three clamping rods 62 and the three abutting rods 63 to prevent the three clamping rods 62 and the three abutting rods 63 from moving.

[0016] Reference Figure 1 and Figure 2 The bottom ends of the four legs 3 are fixedly connected with fixed blocks 71, and one end of the top of the four fixed blocks 71 is threaded with a second bolt 72. The four second bolts 72 are threadedly connected to the surface of the external workbench, and the processing table 1 can be fixedly installed on the external workbench. The top of the connecting rod 64 is fixedly connected with a handle 8. After the plug 66 is pulled out to release the limit on the support block 65, the handle 8 can be held by hand to drive the three clamping rods 62 and the three interference rods 63 to move horizontally through the connecting rod 64, so that the three clamping rods 62 are disengaged from the three clamping holes, and at the same time, the three interference rods 63 are disengaged from the three limit frames 61.

[0017] The implementation principle of the strip metal product bending device of the embodiment of the present application is as follows: when in use, three strip metal products are placed in three limit frames 61 respectively, and one end of the three strip metal products is located at the inner bottom of the support frame 2. Then, the handle 8 is held by hand to drive the three clamping rods 62 and the three abutting rods 63 to move horizontally through the connecting rod 64, so that the three clamping rods 62 pass through the three clamping holes respectively, and the three clamping rods 62 clamp the processing table 1, thereby ensuring that the three abutting rods 63 are respectively located inside the three limit frames 61, and at the same time, the plug 66 passes through the support block 65 and the connecting rod 64 to fix the connecting rod 64 and space it. The three resistance rods 63 are fixed, and the three resistance rods 63 resist the strip metal products placed in the three limit frames 61. At the same time, the three resistance rods 63 cooperate with the three limit frames 61 to resist and limit the four sides of the three strip metal products. After that, after the external reversing valve is opened and the external oil pump is started, the external oil pump draws the oil in the external oil tank and transports it to the external reversing valve through the oil supply pipe. The external reversing valve discharges the oil into the hydraulic cylinder 52 through the oil pipe. The hydraulic rods of the three hydraulic cylinders 52 are pushed by the oil pressure inside the three hydraulic cylinders 52 to drive the bending head 51 to move downward, thereby bending the strip metal products.
