[0027] See Figures 1 - 5 , this embodiment provides a profiled steel arc pressing die device, which mainly consists of a bottom plate 1, a pressing block 2, a limiting rod 3 and a compression spring 4. The bottom plate 1 is rectangular and is horizontally arranged. A plurality of pressing blocks 2 are arranged in parallel on one side of a long side of the bottom plate 1. There are three types of pressing blocks 2, namely a first intermediate pressing block 2-1, a second intermediate pressing block 2-2, six side pressing blocks 2-3 and two edge pressing blocks 2-4. A gap is left between the bottom surfaces of the first intermediate pressing block 2-1, the second intermediate pressing block 2-2, the six side pressing blocks 2-3 and the two edge pressing blocks 2-4 and the upper plate surface of the bottom plate 1.

[0028] The first intermediate pressing block 2-1 and the second intermediate pressing block 2-2 are right trapezoids. The first intermediate pressing block 2-1 and the second intermediate pressing block 2-2 are symmetrically arranged and their inclined waists are adjacent. The edge pressing block 2-4 is strip-shaped, and its length is adapted to the width of the bottom plate 1. The two edge pressing blocks 2-4 are respectively placed on the upper parts of the wide sides of the bottom plate 1. Three side pressing blocks 2-3 are respectively arranged between the first intermediate pressing block 2-1 and the left edge pressing block 2-4, and between the second intermediate pressing block 2-2 and the right edge pressing block 2-4. The side pressing blocks 2-3 are square or rectangular. The first intermediate pressing block 2-1 and the side pressing blocks 2-3, the side pressing blocks 2-3, and between the side pressing blocks 2-3 and the left edge pressing block 2-4 are connected by tension springs 8. The first intermediate pressing block 2-1 and the second intermediate pressing block 2-2 are connected by a tension spring 8. The second intermediate pressing block 2-2 and the side pressing blocks 2-3, the side pressing blocks 2-3, and between the side pressing blocks 2-3 and the right edge pressing block 2-4 are connected by tension springs 8. The tension springs 8 are located at the tops of each pressing block 2, and the two ends of the tension springs 8 are respectively connected to the pressing blocks 2 through connecting pins.

[0029] The inner ends of the first intermediate pressing block 2-1, the second intermediate pressing block 2-2 and the six side pressing blocks 2-3 are respectively provided with hinge assemblies. The hinge assemblies are mainly composed of ear plates 5, pin shafts 6 and ear seats 7. The ear plates 5 are welded to the first intermediate pressing block 2-1, the second intermediate pressing block 2-2 and the side pressing blocks 2-3 respectively, and the ear plates 5 are hinged to the ear seats 7 through the pin shafts 6. The inner end of each ear seat 7 is fixedly connected to the inner end of a limiting rod 3. The outer end of the limiting rod 3 penetrates through the support plate 9. The support plate 9 is parallel to the long side of the bottom plate 1 and is welded thereto. A limiting nut is screwed on the limiting rod 3 outside the support plate 9, and a compression spring 4 is sleeved on the limiting rod 3 inside the support plate 9. The compression spring 4 is located between the support plate 9 and the ear seat 7, and the compression spring 4 resets the pressing block 2.

[0030] A sliding structure is connected between the edge pressing block 2-4 and the bottom plate 1 and between the limiting rod 3 and the bottom plate 1. The sliding structure is composed of a chute 1-1 and a sliding rod 10. The bottom plate 1 is provided with an inverted T-shaped chute 1-1. The chute 1-1 penetrates the width direction of the bottom plate 1. The inverted T-shaped sliding rod 10 is slidably connected to the chute 1-1. The upper end of the sliding rod 10 is fixedly connected to the limiting rod 3 or the edge pressing block 2-4. The sliding structure makes the axis of the limiting rod 3 always parallel to the wide side of the bottom plate 1.

[0031] The working process of this embodiment is ( Figure 6 , Figure 7 as shown): Taking an angle steel as an example, the angle steel 11 to be arc-pressed is fixed in the gap between the first intermediate pressing block 2-1, the second intermediate pressing block 2-2, the side pressing blocks 2-3, the edge pressing block 2-4 and the bottom plate 1. A certain pressure is applied to the arc-pressed angle steel 11. After being subjected to the pressure, the angle steel 11 deforms. During the deformation process of the angle steel 11, the compression spring 4 and the tension spring 8 generate deformations, and a certain limit is applied to the arc-pressed angle steel 11 through the pressing block 2, preventing the angle steel 11 from generating unnecessary deformation amounts due to uneven pressure application during the cold pressing process. After arc-pressing, the pressing block 2 and the limiting rod 3 are reset under the action of the compression spring 4 and the tension spring 8.
