This embodiment is written in a progressive manner.

[0029] like Figures 1 to 5 As shown, a hot press bending machine for angle steel opening and closing angles of the present invention comprises a vertical plate 1, a bending assembly 2 and a conveying assembly 3. A circular hole is opened in the middle of the vertical plate 1, the bending assembly 2 is installed in the circular hole, and the conveying assembly 3 is installed on the side wall of the vertical plate 1. The bending assembly 2 is used to bend the angle steel 4 passing through the circular hole, and the conveying assembly 3 is used to convey the angle steel 4;

[0030] The bending assembly 2 includes two arc seats 5 relatively distributed on the inner wall of the circular hole, each arc seat 5 is provided with a top pressure wheel group and a roller 6, the top pressure wheel group is used to press down one side of one edge of the angle steel 4, and the roller 6 is used to support the other side of one edge of the angle steel 4;

[0031] The top pressure wheel group includes a cone wheel 7, a support plate 8, a support column 9 and a pressure wheel 10, the cone wheel 7 is rotatably mounted on the support plate 8, the support plate 8 is fixed on the arc seat 5, the support column 9 is fixed on the side wall of the support plate 8, and the pressure wheel 10 is rotatably mounted on the support column 9;

[0032] The two conical wheels 7 on the two arc-shaped seats 5 are close to and used for rolling the two surfaces at the inner corner positions of the angle steel 4 .

[0033] In detail, the vertical plate 1 is used to provide a fixing position for the bending component 2 and the conveying component 3. The conveying component 3 can horizontally convey the angle steel 4 heated at high temperature through the bending component 2. The bending component 2 can roll and bend the two edges on the angle steel 4, so as to adjust the opening and closing angles of the angle steel 4. The bending component 2 is composed of two arc seats 5 and rollers 6, cone wheels 7, support plates 8, support columns 9 and pressure wheels 10 on each arc seat 5. The arc seat 5 can support and fix the structure above it. The top pressure wheel group and rollers 6 on the arc seat 5 are distributed up and down, and the top pressure wheel group and rollers 6 cooperate to extrude one side of the angle steel 4. The two arc seats 5 The top pressure wheel group and the roller 6 squeeze the two sides of the angle steel 4, thereby changing the angle between the two sides on the angle steel 4 according to the positional relationship of the two arc seats 5, that is, when the angle steel 4 passes through the two groups of top pressure wheel groups and the two rollers 6, the angle between the two sides on the angle steel 4 changes, thereby achieving the purpose of adjusting the opening and closing angle of the angle steel 4, and the structure can be used to increase or decrease the opening and closing angle of the angle steel 4, thereby achieving the purpose of two-way adjustment, the cone wheel 7 approaches the inner angle of the angle steel 4, and the cone wheel 7 rolls one side of the angle steel 4, the cone wheel 7 and the pressure wheel 10 cooperate to roll the upper surface of one side of the angle steel 4, and the roller 6 lifts the bottom surface of one surface of the angle steel 4.

[0034] When in use, the conveying component 3 conveys the angle steel 4 horizontally through the bending component 2, and the two edges of the angle steel 4 pass through the top pressure wheel group and the roller 6 on the two arc-shaped seats 5 respectively, and the top pressure wheel group and the roller 6 cooperate to roll one edge of the angle steel 4. As the cone wheel 7 and the pressure wheel 10 on the top pressure wheel group roll one edge of the angle steel 4, the angle between the two edges of the angle steel 4 changes, thereby realizing the rolling bending deformation of the opening and closing angles of the angle steel 4, and this method can continuously realize the deformation processing of the angle steel 4, thereby improving the continuity and work efficiency of the processing of the angle steel 4. In actual use, in order to ensure the normal transportation of the angle steel 4 and its ability to completely pass through the bending component 2, the conveying component 3 can be set on both the front and rear sides of the vertical plate 1.

[0035] By using rolling to bend and deform the opening and closing angles of the heated angle steel 4, a continuous bending processing method for the angle steel 4 can be achieved, the continuity of the processing is improved, thereby significantly improving work efficiency and simplifying the operation method; the equipment has the ability to adjust the opening and closing angles of the angle steel in both directions, which can increase or decrease the angle between the two sides, making the processing more flexible and able to adapt to more types of design requirements; by using the conical wheel 7 in the top pressure wheel group to roll one side of the angle steel 4 close to the inner corner position of the angle steel 4, it is convenient to deform one side of the angle steel 4 as a whole, to keep each side of the angle steel 4 flat, and to improve the processing quality of the angle steel 4, and with the use of the roller 6 and the pressure wheel 10, accurate deformation processing of each side of the angle steel 4 can be achieved; in summary, compared with the traditional angle steel bending method, this angle steel opening and closing angle hot press bending machine has significant improvements in processing efficiency, processing accuracy and ease of operation, and is an important technological innovation in the field of angle steel processing.

[0036] Furthermore, the arc-shaped seat 5 slides in an arc shape on the inner wall of the circular hole on the vertical plate 1 , and a power unit for providing a driving force for the movement of the two arc-shaped seats 5 is provided on the vertical plate 1 .

[0037] In detail, the distance and position relationship between the two arc seats 5 can be adjusted by enabling the arc seat 5 to slide on the inner wall of the circular hole on the vertical plate 1. In this way, the bending angle of one side of the diagonal steel 4 can be adjusted by cooperating with the top pressure wheel group and the roller 6 on the arc seat 5, thereby realizing the multi-angle adjustment and deformation work of the diagonal steel 4.

[0038] Furthermore, a first adjustment plate 11 is rolled on the arc seat 5 , a second adjustment plate 12 is slidably arranged on the first adjustment plate 11 , and the first adjustment plate 11 and the second adjustment plate 12 are fastened and connected by bolts, and the roller 6 is rotatably mounted on the second adjustment plate 12 .

[0039] In detail, the arc seat 5 can support the roller 6 through the first adjustment plate 11 and the second adjustment plate 12. By loosening the bolts and adjusting the position of the second adjustment plate 12 on the first adjustment plate 11, the distance between the roller 6 and the top pressure wheel group can be adjusted, thereby facilitating the angle steel 4 of different thicknesses to pass through the gap between the top pressure wheel group and the roller 6, and facilitating the bending deformation of rollers 6 of different specifications.

[0040] Furthermore, the power unit includes a first motor 13 fixed on the side wall of the vertical plate 1, and a gear column 14 is provided at the output end of the first motor 13. Teeth are provided on the side wall of each arc seat 5, and the gear column 14 is engaged with the teeth on the side walls of the two arc seats 5 at the same time.

[0041] In detail, the tooth column 14 is horizontal and perpendicular to the axis of the circular hole on the vertical plate 1. The first motor 13 can drive the two arc seats 5 to move up and down synchronously through the tooth column 14. The arc seats 5 can slide on the inner wall of the circular hole, so the positional relationship between the two arc seats 5 can be adjusted. Since the motion trajectory of the arc seat 5 is arc-shaped, the teeth thereon are helical teeth or arc-shaped teeth, which can ensure that the arc seat 5 and the tooth column 14 always maintain a meshing state when they move relative to each other.

[0042] Further, the conveying assembly 3 includes two side plates 15 in opposite directions, each side plate 15 is provided with two sliders 16 for vertical sliding, the two sliders 16 are distributed up and down, a pressure column 17 is connected between the two sliders 16 opposite to each other on the two side plates 15, and the pressure column 17 rotates on the slider 16, and a push-pull unit is provided on the side plate 15, and the push-pull unit is used to adjust the distance between the two sliders 16 on the side plate 15;

[0043] A second motor 18 is rolled on one side plate 15 , a worm 19 is provided at the output end of the second motor 18 , a worm wheel 20 is meshed on the worm 19 , and the worm wheel 20 is installed on a pressure column 17 .

[0044] In detail, the push-pull unit can drive the two sliders 16 on the side plate 15 to move closer to or away from each other, thereby driving the two pressure columns 17 to move closer to or away from each other. When the two pressure columns 17 move closer to each other, they can squeeze the angle steel 4 passing through the gap between the two pressure columns 17. At this time, the second motor 18 can drive a pressure column 17 to rotate through the worm 19 and the worm gear 20, thereby facilitating the lateral transportation of the angle steel 4.

[0045] Furthermore, the push-pull unit includes an oil cylinder 21 disposed on the side plate 15 , and two push-pull rods 22 are rotatably disposed at the output end of the oil cylinder 21 . The two push-pull rods 22 are relatively inclined, and the two push-pull rods 22 are rotatably connected to the two sliders 16 , respectively.

[0046] In detail, when the oil cylinder 21 is extended or retracted, it can drive the two sliders 16 to move toward or away from each other synchronously through the two push-pull rods 22, thereby adjusting the distance between the two pressure columns 17.

[0047] Furthermore, the oil cylinder 21 slides vertically on the side plate 15 , and the oil cylinder 21 and the side plate 15 are connected via a leaf spring 23 .

[0048] In detail, since the length of each side of the angle steel 4 can be of various specifications, the distance between the two pressure columns 17 needs to be adjusted according to the different specifications of the angle steel 4. When the two pressure columns 17 squeeze the angle steel 4, since the two pressure columns 17 move synchronously, the position of the angle steel 4 can be used to automatically adjust the moving positions of the two pressure columns 17 and the two sliders 16 in the opposite direction. At this time, the two sliders 16 will drive the cylinder 21 to slide vertically on the side plate 15, and the leaf spring 23 will undergo elastic deformation, so that the conveying component 3 can automatically adapt to the angle steel 4, and the leaf spring 23 can provide a reset elastic force for the cylinder 21.

[0049] Furthermore, a reversing ring 24 is rotatably provided on the side wall of the vertical plate 1, and both side plates 15 are fixed on the reversing ring 24. A third motor 25 and a transmission wheel 26 for providing power for the rotation of the reversing ring 24 are provided on the vertical plate 1, and the transmission wheel 26 is connected to the reversing ring 24 in a transmission manner.

[0050] In detail, the third motor 25 is fixed on the vertical plate 1, the transmission wheel 26 is installed on the output end of the third motor 25, and the transmission wheel 26 is connected to the reversing ring 24. The third motor 25 can drive the two side plates 15 to rotate through the transmission wheel 26 and the reversing ring 24, thereby adjusting the position of the two side plates 15, which is convenient for adjusting the direction of the two pressure columns 17.

[0051] When the lengths of the two sides of the angle steel 4 are inconsistent, the angle of the pressure column 17 can be adjusted so that the pressure column 17 can contact the two sides of the angle steel 4. When the angle steel 4 needs to be bent and deformed, one pressure column 17 is located above the opening and closing angle of the angle steel 4. In this way, when the two pressure columns 17 squeeze the angle steel 4, the pressure column 17 located at the opening and closing angle of the angle steel 4 can squeeze the two sides of the angle steel 4 outward for external support, thereby pre-bending the angle steel 4. When the opening and closing angle of the angle steel 4 needs to be reduced, the two pressure columns 17 can be located on both sides of the opening and closing angle of the angle steel 4 by rotating the reversing ring 24. In this way, when the two pressure columns 17 squeeze the angle steel 4, the two sides of the angle steel 4 can be brought close to each other, thereby pre-bending the angle steel 4.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
