Description

Technical Field

[0001] The utility model relates to a CZ-shaped steel D-track double butterfly wheel forming device, belonging to the technical field of profile forming devices. Background Art

[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 and Z-shaped steel are common profiles, which play a pivotal role in the field of construction engineering or equipment manufacturing. At present, C-shaped steel and Z-shaped steel are processed and formed by CZ purlin machines during the production process. At present, in the process of processing C-shaped steel and Z-shaped steel, the traditional CZ purlin machine first bends the raw material steel plate into an L-shaped profile, and then processes the L-shaped steel into C-shaped steel or Z-shaped steel through the butterfly wheel group and the leaning wheel according to the needs. However, due to the different wall thicknesses of the raw material steel plates, in order to adapt to the raw material steel plates with different wall thicknesses, the gap of the butterfly wheel group needs to be adjusted. The traditional adjustment method is to adjust the gap by manual feeler gauge, which has the problem of troublesome operation. At the same time, when the traditional CZ purlin machine processes the L-shaped steel into C-shaped steel or Z-shaped steel, its steel D track needs to rotate, so that the traditional CZ purlin machine needs to have a more complex structure to meet the corresponding action of the steel D track, and there is a problem of complex structure.

DETAILED DESCRIPTION

[0024] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example: Please refer to Figures 1 to 5 The present embodiment provides a CZ-shaped steel D-track double butterfly wheel forming device, including a gantry 1, on which a first butterfly wheel group 2 and a second butterfly wheel group 3 are arranged in an upper and lower distributed manner.

[0026] The first butterfly wheel assembly 2 includes a first butterfly wheel shaft 21, a slide groove 5 is provided on the gantry 1, a sliding block 4 is slidably connected in the slide groove 5, and the sliding block 4 can slide up and down along the slide groove 5 in the slide groove 5, and the first butterfly wheel shaft 21 is movably passed through the sliding block 4, and the first butterfly wheel shaft 21 is movably passed through the sliding block 4 to be set through the gantry 1. The left end of the first butterfly wheel shaft 21 is rotatably connected with a first butterfly wheel body 22, and in order to facilitate the processing of the required steel shape, the first butterfly wheel body 22 is tilted and arranged on the first butterfly wheel shaft 21, and a lift 6 is also arranged on the top of the gantry 1, and the lifting shaft of the lift 6 extends into the slide groove 5 and is fixedly connected with the top of the sliding block 4, and the lift 6 can drive the sliding block 4 to move up and down along the slide groove 5 through the lifting action of the lifting shaft, thereby driving the first butterfly wheel shaft 21 to move, and then the first butterfly wheel assembly 2 can move up and down on the gantry 1.

[0027] To adapt to the angle forming of C-shaped steel and Z-shaped steel, the coordinates of the first butterfly wheel body 22 in the X-axis direction should also be adjustable. For this purpose, in this embodiment, a first adjusting nut 23 and a first mounting block 24 are sequentially arranged along the direction close to the gantry 1 on the right end of the first butterfly wheel shaft 21. An external thread is provided on the right end of the first butterfly wheel shaft 21 so that the first adjusting nut 23 can be screwed onto the first butterfly wheel shaft 21. The first adjusting nut 23 is also rotatably connected to the first mounting block 24. The first mounting block 24 is arranged in a "C" shape. The first butterfly wheel shaft 21 movably passes through the first mounting block 24. The first mounting block 24 is fixedly connected to the sliding block 4. A first spring 25 is also provided between the first mounting block 24 and the sliding block 4. The first spring 25 is movably sleeved on the first butterfly wheel shaft 21. A first limiting step 26 adapted to the first spring 25 is also provided on the first butterfly wheel shaft 21. In this embodiment, the first limiting step 26 is arranged on the left side of the first spring 25. When it follows the first butterfly wheel shaft 21 to move to the right later, it can cooperate with the first mounting block 24 to squeeze the first spring 25. At the same time, the first limiting step 26 can pass through the sliding block 4. Through the above settings, when it is necessary to adjust the coordinates of the first butterfly wheel body 22 in the X-axis direction, by rotating the first adjusting nut 23, the first adjusting nut 23 cooperates with the external thread provided on the first butterfly wheel shaft 21, so that the first butterfly wheel shaft 21 can move in the corresponding direction. That is, during the rotation of the first adjusting nut 23, according to the rotation direction, the first butterfly wheel shaft 21 will move left and right correspondingly to drive the first butterfly wheel body 22 to move correspondingly, so as to achieve the adjustment. When the first butterfly wheel shaft 21 moves to the right, the first limiting step 26 follows the first butterfly wheel shaft 21 to move. Cooperating with the first mounting block 24, it will squeeze the first spring 25 to generate elastic potential energy. When the first butterfly wheel shaft 21 moves to the left, at this time, the first limiting step 26 will move away from the first spring 25. The first spring 25 will play an auxiliary role in pushing the first butterfly wheel shaft 21 to move left during this process.

[0028] The second butterfly wheel group 3 includes a second butterfly wheel shaft 31. The second butterfly wheel shaft 31 is movably arranged through the gantry 1. A second butterfly wheel body 32 is rotatably connected to the left end of the second butterfly wheel shaft 31. To facilitate the processing of the required section steel shape, the second butterfly wheel body 32 is inclined and arranged on the second butterfly wheel shaft 31. The second butterfly wheel body 32 and the first butterfly wheel body 22 form an "eight" - shaped structure. To adapt to the angle forming of C - shaped steel and Z - shaped steel, the coordinate of the second butterfly wheel body 32 in the X - axis direction should also be adjustable. For this reason, in this embodiment, a second adjusting nut 33 and a second mounting block 34 are sequentially arranged on the right end of the second butterfly wheel shaft 31 along the direction close to the gantry 1. External threads are provided on the right end of the second butterfly wheel shaft 31 so that the second adjusting nut 33 can be screwed onto the second butterfly wheel shaft 31. The second adjusting nut 33 is also rotatably connected to the second mounting block 34. The second mounting block 34 is arranged in a "C" - shaped structure. The second butterfly wheel shaft 31 movably passes through the second mounting block 34. The second mounting block 34 is fixedly connected to the gantry 1. A second spring 35 is also arranged between the second mounting block 34 and the gantry 1. The second spring 35 is movably sleeved on the second butterfly wheel shaft 31. A second limiting step 36 adapted to the second spring 35 is also provided on the second butterfly wheel shaft 31. In this embodiment, the second limiting step 36 is arranged on the left side of the second spring 35. When it moves to the right following the second butterfly wheel shaft 31 later, it can cooperate with the second mounting block 34 to squeeze the second spring 35. At the same time, the second limiting step 36 can pass through the gantry 1. Through the above - mentioned arrangement, when the coordinate of the second butterfly wheel body 32 in the X - axis direction needs to be adjusted, by rotating the second adjusting nut 33, the second adjusting nut 33 cooperates with the external threads provided on the second butterfly wheel shaft 31, so that the second butterfly wheel shaft 31 can move in the corresponding direction. That is, during the rotation of the second adjusting nut 33, according to the rotation direction, the second butterfly wheel shaft 31 will move leftward and rightward accordingly, so as to drive the second butterfly wheel body 32 to move correspondingly, thus realizing the adjustment. When the second butterfly wheel shaft 31 moves to the right, the second limiting step 36 moves following the second butterfly wheel shaft 31. Cooperating with the second mounting block 34, it will squeeze the second spring 35, making it generate elastic potential energy. When the second butterfly wheel shaft 31 moves to the left, at this time, the second limiting step 36 will move away from the second spring 35, and the second spring 35 will play an auxiliary role in pushing the second butterfly wheel shaft 31 to move leftward during this process.

[0029] In order to ensure that the first butterfly wheel group 2 and the second butterfly wheel group 3 are unlikely to fall off during processing, in this embodiment, a first butterfly wheel support 10 is further provided above the first butterfly wheel group 2, and the first butterfly wheel support 10 is fixedly arranged on the gantry 1, and a second butterfly wheel support 11 is further provided below the second butterfly wheel group 3, and the second butterfly wheel support 11 is fixedly arranged on the gantry 1. The first butterfly wheel support 10 and the second butterfly wheel support 11 both play a limiting role to prevent the corresponding first butterfly wheel group 2 and the second butterfly wheel group 3 from falling off. In actual use, the arrangement of the first butterfly wheel support 10 and the second butterfly wheel support 11 on the gantry 1 can be determined according to actual needs.

[0030] To facilitate the adjustment of the first butterfly wheel shaft 21 and the second butterfly wheel shaft 31, a first adjustment scale 27 is provided on the side wall of the first adjusting nut 23 away from the first mounting block 24, and a second adjustment scale 37 is provided on the side wall of the second adjusting nut 33 away from the second mounting block 34. The staff can judge the rotation stroke of the first adjusting nut 23 and the second adjusting nut 33 by observing the scales on the first adjustment scale 27 and the second adjustment scale 37, and thus can determine the adjustment length of the first butterfly wheel shaft 21 and the second butterfly wheel shaft 31 according to the rotation stroke.

[0031] The gantry 1 is also movably provided with a supporting wheel group 7, which includes a mounting frame 71, and the middle part of the mounting frame 71 is rotatably connected to a vertically arranged supporting wheel body 72, and a connecting shaft 73 is provided on the top of the mounting frame 71, and a threaded hole 74 is provided on the connecting shaft 73, and a connecting block 12 is provided on the first butterfly wheel support 10, and an adjusting screw rod 8 is movably passed through the connecting block 12, and the adjusting screw rod 8 is movably passed through the connecting block 12 and is threadedly connected to the threaded hole 74 to be connected with the connecting shaft 73, and crescent-shaped grooves 75 are provided on the side walls of the mounting frame 71, and limit blocks 9 are symmetrically arranged on the gantry 1, and the limit blocks 9 on both sides are movably connected to the corresponding side grooves 75, and the shapes of the limit blocks 9 on both sides are smaller than the corresponding side grooves 75, and the limit blocks 9 on both sides can be moved from one side end of the corresponding side groove 75 to the other side end, so that the subsequent mounting frame 71 can perform corresponding movements. Through the above-mentioned arrangement, when the angle of the supporting wheel group 7 needs to be adjusted, by rotating the adjusting screw 8, the adjusting screw 8 will penetrate into or out of the threaded hole 74 according to the rotation direction, thereby generating a pushing or pulling force on the connecting shaft 73, thereby pushing or pulling the mounting frame 71, so that the limit block 9 will move in a crescent shape along the groove 75, so that the supporting wheel group 7 can be adjusted to a suitable angle under the action of the adjusting screw 8 when C-shaped steel or Z-shaped steel needs to be processed, so as to facilitate subsequent processing.

[0032] According to the working principle of the utility model, during processing, the staff starts working by controlling the elevator 6 to adjust the gap between the first butterfly wheel group 2 and the second butterfly wheel group 3 according to the wall thickness of the raw material steel plate to be processed, so as to adapt to the wall thickness of the raw material steel plate to be processed. After that, the staff adjusts the first butterfly wheel group 2, the second butterfly wheel group 3 and the supporting wheel group 7 accordingly by rotating the first adjusting nut 23, the second adjusting nut 33 and the adjusting screw 8 according to the processing requirements, so as to process the required C-shaped steel and Z-shaped steel.
