[0015] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0016] like Figure 1 and Figure 2 As shown, the soft row bending tooling provided in the embodiment of the present application comprises an upper die 1 and a lower die 2, the lower end surface of the upper die 1 is provided with a bending protrusion 10, the upper end surface of the lower die 2 is provided with a bending profiling groove 20, and the high end surface 21 and the low end surface 22 are respectively located on both sides of the bending profiling groove 20, and also comprises a No. 1 limit block 3 and a No. 2 limit block 4 arranged on both sides of the lower die 2, the upper end of the No. 1 limit block 3 protrudes the high end surface 21, and a floating member 5 is further arranged between the low end surface 22 and the No. 2 limit block 4, the floating member 5 comprises a lifting block 51 of the same length as the bending profiling groove 20, a lifting rod 52 arranged on the lower die 2 along the vertical sliding, and a plurality of springs 53 respectively sleeved on the lifting block 51, the upper end of the lifting rod 52 is connected to the lifting block 51, and the two ends of the spring 53 are respectively against the lower die 2, and when the spring 53 is in a natural state, the upper end surface of the lifting block 51 is flush with the high end surface 21.

[0017] In actual use, when stamping is not performed, the upper die 1 and the lower die 2 are not in contact, and the upper die 1 and the floating part 5 are not in contact. At this time, the upper end surface of the floating part 5 is flush with the high end surface 21. Then, a number of products to be bent are placed on the lower die 2, so that the product is perpendicular to the extension direction of the bending profiling groove 20, and it is ensured that the two ends of the product are respectively against the No. 1 limit block 3 and the No. 2 limit block 4. Then, the upper die 1 is pressed down, and the bending protrusion 10 first squeezes the product downward into the bending profiling groove 20. As this pressing process continues, the lower end surface of the upper die 1 begins to squeeze the unbent part of the product. At this time, the product will drive the floating part 5 to move downward. Specifically, after the product is subjected to the pressure of the upper die 1, the lifting block 51 is pressed down, so that the lifting block 51 moves downward, and the spring 53 is compressed. When the upper die 1 is opened, the spring 53 is reset, driving the lifting block 51 to reset.

[0018] In the above design, the floating part 5 is provided to cooperate with the high-end surface 21 to support the two ends of the product, and the first limit block 3 and the second limit block 4 are used to limit the two ends of the product. Due to the floating performance of the floating part 5, the normal movement of the product during deformation can be guaranteed, which will not interfere with the bending of the product, and can realize the placement and bending of the products in batches, effectively improving the work efficiency and ensuring the forming accuracy. Avoiding the hand-held soft row can improve the safety of the standard bending machine.

[0020] In actual use, when the floating member 5 is working, the lifting block 51 is lifted and lowered along the groove 100 , and the lifting rod 52 is lifted and lowered along the vertical hole 23 .

[0021] In the above design, a step is provided so that the second limit block 4 and the step form a groove 100, which can ensure the stability of the floating member 5 when it is working.

[0022] Specifically: Figure 2 As shown, a limiting end 54 is also provided at the lower end of the lifting rod 52 , and the limiting end 54 is located below the lower end surface of the lower mold 2 .

[0023] During actual use, the lower end of the lifting rod 52 is limited by the limiting end 54 to prevent the lifting rod 52 from being separated from the lower mold 2.

[0024] In the above design, the lifting rod 52 and the lower mold 2 can be effectively fixed relative to each other by setting the limiting end 54.
