DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] The fireproof rolling shutter splint forming device of the utility model is as follows Figures 1 to 4As shown, it includes a horizontal supporting table 1, a horizontal positioning roller 2 is arranged above the supporting table 1, and a positioning gap is arranged between the positioning roller 2 and the supporting table 1; a bracket 3 is arranged on one side of the supporting table 1, and a horizontal rotating shaft 4 and a horizontal clamping shaft 5 are arranged on the bracket 3, the rotating shaft 4 and the clamping shaft 5 are both cantilever shafts, and the rotating shaft 4 is fixedly connected to the clamping shaft 5 through a connecting frame 6, a clamping gap is arranged between the rotating shaft 4 and the clamping shaft 5, and the rotating shaft 4 is connected to a first driving mechanism 7 for driving the rotating shaft 4 to rotate.

[0020] The support table 1 can be made of a plate with a certain thickness, such as a stainless steel plate, and a group of support feet are used to support the support table 1 so that the support table 1 is at a suitable height. The positioning roller 2 is used to position the raw material plate, and the number of positioning rollers 2 can be one, two, three, etc. The height of the positioning spacing between the positioning roller 2 and the support table 1 is slightly larger than the thickness of the raw material plate, so that the raw material plate can pass through the positioning spacing, and the raw material plate can move horizontally in the positioning spacing. The bracket 3 is used to support the rotating shaft 4, and the rotating shaft 4 can be installed on the bracket through a bearing. The clamping shaft 5 is used to limit one side of the raw material plate, and the clamping spacing is slightly larger than the thickness of the raw material plate, so that the edge of the raw material plate can extend into the clamping spacing, and the clamping shaft 5 can clamp the raw material plate. One end of the clamping shaft 5 is fixedly connected to the rotating shaft 4 through a connecting frame 6, and the connecting frame 6 can be made of a plate. Since the clamping shaft 5 and the rotating shaft 4 are connected as a whole, when the rotating shaft 4 rotates, it can drive the clamping shaft 5 to rotate synchronously. When the clamping shaft 5 is at the highest point, the clamping spacing and the positioning spacing are at the same height, ensuring that the raw material plate can be translated into the clamping spacing after passing through the positioning spacing. The first driving mechanism 7 is used to drive the rotating shaft 4 to rotate, and a servo motor or other equipment can be used. After the arc segment 102 on one side of the fireproof roller shutter splint is formed, it will be wrapped around the outer wall of the rotating shaft 4. Only by moving the fireproof roller shutter splint axially can the arc segment 102 be separated from the rotating shaft 4. Therefore, the rotating shaft 4 and the clamping shaft 5 are both cantilever shafts, that is, one end of the rotating shaft 4 is installed on the bracket 3, and the other end is suspended. Similarly, one end of the clamping shaft 5 is fixed on the connecting frame 6, and the other end is suspended, so as to facilitate the axial movement of the workpiece after forming and remove the workpiece.

[0021] The use process of the utility model is as follows: the raw material sheet passes through the positioning spacing until one side of the raw material sheet enters the clamping spacing, so that the clamping shaft 5 clamps the raw material sheet; then the first driving mechanism 7 is started, the first driving mechanism 7 drives the rotating shaft 4 to rotate, and the clamping shaft 5 rotates synchronously with the rotating shaft 4. When the clamping shaft 5 rotates, it pulls the raw material sheet to move, and at the same time drives the edge of the raw material sheet to bend and wrap around the rotating shaft 4, so as to gradually form an arc segment 102. During the movement of the raw material sheet, the positioning roller 2 positions the raw material sheet so that the raw material sheet moves smoothly. When the curling arc of the edge of the raw material sheet meets the requirements, the first driving mechanism 7 stops running, pulls the splint bearing to move, and removes the splint from the rotating shaft 4 and the supporting table 1. Then the other side of the raw material sheet passes through the positioning spacing, and the arc segment 102 is formed at the edge of the other side.

[0022] from Figure 5 It can be seen that the straight segment 101 and the arc segment 102 are connected by the inclined segment, and the angle between the inclined segment and the straight segment 101 is an obtuse angle. In order to form the inclined segment, the bracket 3 is connected to the first lifting mechanism 8, and the side of the support table 1 facing the rotating shaft 4 is an inclined surface. After the arc segment 102 is formed, the arc segment 102 is sleeved on the outer wall of the rotating shaft 4. At this time, the first lifting mechanism 8 is used to drive the bracket 3 to move downward by an appropriate distance, and the bracket 3 can drive the rotating shaft 4, the clamping shaft 5 and the arc segment 102 to move downward until the raw material plate connected to the arc segment 102 is bent and fits on the inclined surface of the support table 1, and the inclined segment can be obtained. The plate located on the upper surface of the support table 1 can be used as the straight segment 101.

[0023] In order to ensure that the bracket 3 is lifted and lowered stably, the first lifting mechanism 8 is a hydraulic cylinder, which is fixedly mounted on a fixed bracket 9, which is fixed to the ground. A vertical guide column 10 is provided on the fixed bracket 9, and the bracket 3 slides with the guide column 10.

[0024] The positioning roller 2 can also be a cantilever. In order to improve the stability of the positioning roller 2, the two ends of the positioning roller 2 are installed on the positioning frame 11. The two sides of the support table 1 are provided with a frame 15. The top of the frame 15 is provided with a crossbeam 16. The crossbeam 16 is located above the positioning frame 11, and the positioning frame 11 is connected to the crossbeam 16 through the second lifting mechanism 12. After the splint is formed, the second lifting mechanism 12 drives the positioning frame 11 to move upward, and the positioning frame 11 drives the positioning roller 2 to move upward for a distance, and the splint can be removed. In addition, the height of the positioning spacing can also be adjusted by the second lifting mechanism 12. The second lifting mechanism 12 can specifically adopt a hydraulic cylinder.

[0025] The positioning roller 2 is connected to a second driving mechanism 13 for driving the positioning roller 2 to rotate. Both ends of the positioning roller 2 can be installed on the positioning frame 11 through bearings. The second driving mechanism 13 can drive the positioning roller 2 to rotate. After the raw material sheet enters the positioning spacing, the positioning roller 2 presses the raw material sheet, and then the second driving mechanism 13 is started to drive the positioning roller 2 to rotate, thereby driving the raw material sheet to move, so that the side of the raw material sheet enters the pressing spacing.

[0026] The outer walls of the rotating shaft 4 and the pressing shaft 5 are both provided with elastic sleeves 14, which can protect the raw material plates and prevent the raw material plates from being pinched.

[0027] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
