[0002] Profiles are objects with a certain geometric shape made from iron or steel and other materials with a certain strength and toughness through rolling, extrusion, casting and other processes; profiles can be used alone or further processed into other manufactured products, and are often used in building structures and manufacturing and installation.

[0003] C-shaped steel is a common profile, which plays a vital role in the field of construction engineering or equipment manufacturing. At present, C-shaped steel is processed and formed by C-shaped purlin machines during the production process. At present, the traditional C-shaped purlin machine first bends the raw material steel plate into an L-shaped profile during the processing of C-shaped steel, and then processes the L-shaped steel into C-shaped steel through the butterfly wheel group in conjunction with the supporting wheel and the supporting wheel according to the demand. However, the traditional C-shaped purlin machine can only process a C-shaped steel with a waist height angle, and the current market has more requirements for the waist height angle of C-shaped steel. The C-shaped purlin machine that can only process a C-shaped steel with a waist height angle obviously cannot meet the market demand well, so it needs to be improved. Utility Model Content

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example: Please refer to Figures 1 to 5 The present embodiment provides a C-shaped steel waist height adjustable angle forming device, including a gantry 1, on which a butterfly wheel group 2, a supporting wheel group 3 and a supporting wheel group 4 are arranged, wherein the butterfly wheel group 2 is arranged above the supporting wheel group 3 and the supporting wheel group 4.

[0025] The butterfly wheel assembly 2 includes a butterfly wheel shaft 21, a second slide groove 8 is provided on the gantry 1, a second slider 9 is slidably connected in the second slide groove 8, and the second slider 9 can slide up and down along the second slide groove 8 in the second slide groove 8. The butterfly wheel shaft 21 is movably passed through the second slider 9, and the butterfly wheel shaft 21 is movably passed through the second slider 9 to pass through the gantry 1. A lift 10 is provided on the top of the gantry 1, and the lifting shaft of the lift 10 extends vertically downward into the second slide groove 8 and is fixedly connected with the second slider 9; when the lift 10 starts working, it can drive the second slider 9 to move up and down along the second slide groove 8 through the lifting action of the lifting shaft, thereby driving the butterfly wheel shaft 21 to move up and down accordingly, so as to adapt to steel materials of different thicknesses; a butterfly wheel body 22 is rotatably connected to the left end of the butterfly wheel shaft 21, and in order to facilitate the processing of the required steel shape, the butterfly wheel body 22 is inclined and arranged on the butterfly wheel shaft 21.

[0026] The supporting roller assembly 3 includes a supporting roller shaft 31, which is rotatably connected to the gantry 1. A supporting roller body 32 is fixedly connected to the end of the supporting roller shaft 31 away from the gantry 1. The supporting roller body 32 is arranged close to the butterfly wheel body 22. A gap is left between the supporting roller body 32 and the butterfly wheel body 22 for the steel material to be processed to pass through.

[0027] The wheel group 4 includes a wheel bracket 41, on which a wheel body 42 arranged vertically is rotatably connected, a connecting shaft 43 is fixedly arranged at the bottom of the wheel bracket 41, a threaded hole 44 is provided on the connecting shaft 43, an adjusting screw rod 5 is movably penetrated through the gantry 1, and the adjusting screw rod 5 is threadedly connected and arranged in the threaded hole 44; a first slide groove 45 arranged in a crescent shape is provided on the left and right side walls of the wheel bracket 41, a connecting block 6 is provided on the gantry 1, and a first slider 7 is provided on the left and right side walls of the connecting block 6, and the first sliders 7 on both sides are slidably connected to the first slide groove 45 on the corresponding side; when the adjusting screw rod 5 rotates, the first sliders 7 on both sides can slide in the first slide groove 45 on the corresponding side, so that the wheel group 4 can perform a corresponding swinging motion on the gantry 1.

[0028] Through the above-mentioned settings, when processing C-shaped steel, the elevator 10 is controlled to start working according to the steel material, so that the elevator 10 adjusts the gap between the supporting wheel body 32 and the butterfly wheel body 22 by adjusting the vertical height of the butterfly wheel shaft 21 to adapt to the thickness of the steel material, and then the steel material is placed in the gap between the supporting wheel body 32 and the butterfly wheel body 22, so that it can pass through the supporting wheel body 32 and the butterfly wheel body 22 under the action of the external conveying device, and then according to the processing requirements, the adjusting screw rod 5 is rotated. When the adjusting screw rod 5 moves into or out of the threaded hole 44 according to the rotation direction, it will generate a pushing or pulling force on the connecting shaft 43, thereby pushing or pulling the supporting wheel bracket 41, so that the first slider 7 can move in a crescent shape along the first slide groove 45, thereby driving the supporting wheel bracket 41 to swing accordingly on the gantry 1, so as to adjust the angle of the supporting wheel body 42. After the supporting wheel body 42 has adjusted its angle, the external conveying device is started to convey the steel material to the gap between the supporting wheel body 32 and the butterfly wheel body 22. The supporting wheel body 42 can bend the steel material entering into the gap, thereby processing a C-shaped steel with a required waist height angle. The supporting wheel body 42 with different angles can process C-shaped steel with different waist height angles, which can well meet on-site needs.

[0029] To facilitate the processing of C-shaped steel with the required waist height angle, a first adjustment scale 46 is provided on one side wall of the idler support 41. The setting of the first adjustment scale 46 enables the staff to determine the angle of the idler body 42 according to the corresponding value on the first adjustment scale 46, so that the staff can quickly determine the waist height angle of the C-shaped steel that can be processed by the idler body 42 at this angle, facilitating the use of the staff.

[0030] To ensure the stability of the adjusting screw rod 5 installed on the gantry 1, an installation block 24 for installing the adjusting screw rod 5 is also fixedly provided on the gantry 1, and the adjusting screw rod 5 is movably installed on the installation block 24 through common structures such as bearings.

[0031] To adapt to the subsequent forming of the overall angle of the C-shaped steel, the coordinate of the butterfly wheel body 22 in the X-axis direction should also be adjustable. For this purpose, in this embodiment, an adjusting nut 23 and an installation block 24 are sequentially arranged along the direction close to the gantry 1 on the right end of the butterfly wheel shaft 21. The right end of the butterfly wheel shaft 21 is provided with external threads so that the adjusting nut 23 can be screwed onto the butterfly wheel shaft 21. The adjusting nut 23 is also rotatably connected to the installation block 24. The installation block 24 is arranged in a "C" - shaped structure. The butterfly wheel shaft 21 movably passes through the installation block 24. The installation block 24 is fixedly connected to the second slider 9. A spring 25 is also provided between the installation block 24 and the second slider 9. The spring 25 is movably sleeved on the butterfly wheel shaft 21. A limiting step 26 adapted to the spring 25 is also provided on the butterfly wheel shaft 21. The limiting step 26 is arranged on the left side of the spring 25. When it moves to the right following the butterfly wheel shaft 21 later, it can cooperate with the installation block 24 to squeeze the spring 25. At the same time, the limiting step 26 can pass through the sliding block. Through the above settings, when it is necessary to adjust the coordinate of the butterfly wheel body 22 in the X-axis direction, by rotating the adjusting nut 23, the adjusting nut 23 cooperates with the external threads provided on the butterfly wheel shaft 21, enabling the butterfly wheel shaft 21 to move in the corresponding direction. That is, during the rotation of the adjusting nut 23, according to the rotation direction, the butterfly wheel shaft 21 will move left and right correspondingly to drive the butterfly wheel body 22 to move correspondingly, thereby achieving the adjustment. When the butterfly wheel shaft 21 moves to the right, the limiting step 26 follows the butterfly wheel shaft 21 to move, and in cooperation with the installation block 24, it will squeeze the spring 25 to generate elastic potential energy. When the butterfly wheel shaft 21 moves to the left, at this time, the limiting step 26 will move away from the spring 25, and the spring 25 will play a role in assisting the pushing of the butterfly wheel shaft 21 to move left during this process.

[0032] To facilitate the adjustment of the butterfly wheel shaft 21, a second adjustment scale 27 is provided on the side wall of the adjusting nut 23 away from the mounting block 24. The staff can judge the rotation stroke of the adjusting nut 23 by observing the scale on the second adjustment scale 27, and thus can determine the adjustment length of the butterfly wheel shaft 21 according to the rotation stroke.

[0033] In order to ensure that the butterfly wheel assembly 2 is unlikely to fall off during processing, in this embodiment, a butterfly wheel support 12 is further provided above the butterfly wheel assembly 2, and the butterfly wheel support 12 is fixedly arranged on the gantry 1. The butterfly wheel support 12 plays a limiting role to prevent the butterfly wheel assembly 2 from falling off when it is subjected to an upward force during processing. In actual use, the arrangement of the butterfly wheel support 12 on the gantry 1 can be determined according to actual needs.
