[0001] The utility model relates to the technical field of cutting frames, in particular to a U-shaped steel cutting frame. Background Technique

[0002] A pigsty refers to a building specifically used for pig breeding. The structure of a pigsty generally adopts a steel structure framework, which is usually composed of U-shaped steel through cutting and welding. When cutting U-shaped steel, a cutting frame is needed. When some U-shaped steel cutting frames are used, first place the U-shaped steel on the feeding rollers above the cutting frame, and then the feeding rollers are rotated by an external power device. The contact friction between the feeding rollers and the U-shaped steel is used to cut and convey it. However, during the cutting process of U-shaped steel, the U-shaped steel itself is prone to horizontal sliding with the feeding rollers, resulting in longitudinal shaking of the cutting part, affecting the cutting accuracy of U-shaped steel and being inconvenient to use.

Uniformly distributed rotating shafts three are rotatably connected through bearings inside the limiting frames. Steel material conveying rollers are arranged on the outer sides of the rotating shafts three;

[0006] Centering and limiting mechanism: It is arranged inside the limiting frame. This device can automatically center, limit and convey U-shaped steel of different models, avoid relative horizontal sliding between the U-shaped steel and the cutting frame, and further improve the cutting accuracy of U-shaped steel, making it convenient to use.

[0007] Furthermore, it further includes a single-chip microcomputer. The single-chip microcomputer is arranged on the front side of the support frame.

[0008] Further, the limiting and centering mechanism includes pressure sensors, telescopic columns, longitudinal movement seats, second rotating shafts, and smooth rollers. The pressure sensors are all arranged inside the limiting frames, and the pressure sensors are electrically connected to the single-chip microcomputer bidirectionally. Circular seats are arranged on one side of the pressure sensors close to the center of the support frame. Longitudinal movement seats are arranged on one side of the circular seats close to the center of the support frame through telescopic columns. Smooth rollers are rotatably connected to the inside of the longitudinal movement seats through second rotating shafts, and the pressure readings are used to automatically cut, center, extrude, and fix the U-shaped steel by the steel conveying rollers.

[0009] Further, the limiting and centering mechanism further includes springs.

[0012] Further, guide rods are evenly distributed between the connecting seats, and the limiting frames are all slidably connected to the guide rods, preventing the limiting frames from rotating during longitudinal movement.

Subsequently, the single-chip microcomputer starts the second motor, and its output shaft drives the bidirectional lead screw to rotate. The bidirectional lead screw is connected by threads, causing the limit frame to move towards the center of the device. The limit frame drives the corresponding steel conveying rollers to squeeze and fix the front and rear sides of the U-shaped steel. During this process, the single-chip microcomputer starts the pressure sensor, which detects the longitudinal pressure on the round seat and transmits the detection result to the single-chip microcomputer in the form of an electrical signal. As the limit frame moves longitudinally, the outer side of the smooth roller first contacts the side of the U-shaped steel. As the limit frame continues to approach the U-shaped steel, the smooth roller is pressed, and the telescopic end of the telescopic column and the spring contract. The pressure sensor detects the pressure on the round seat and uploads it. When the values measured by the front and rear pressure sensors are the same and reach a certain level, the single-chip microcomputer shuts down the second motor.

This U-shaped steel cutting frame can automatically center and limit different models of U-shaped steel and convey them, avoiding relative horizontal sliding between the U-shaped steel and the cutting frame, thereby improving the cutting accuracy of the U-shaped steel and being easy to use.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1-2 , this embodiment provides a technical solution: a U-shaped steel cutting frame, including a support frame 1 and a limit centering mechanism 8;

[0020] Support frame 1: Inside it, there are uniformly distributed first rotating shafts 3 rotatably connected by bearings. Longitudinal auxiliary rollers 4 are arranged on the outer sides of the first rotating shafts 3. Connecting seats 5 are arranged on the front and rear sides of the support frame 1. A bidirectional lead screw 6 is rotatably connected between the connecting seats 5 by bearings. Uniformly distributed limit frames 7 are threadedly connected to the outer side of the bidirectional lead screw 6. Inside the limit frames 7, there are uniformly distributed third rotating shafts 9 rotatably connected by bearings. Steel conveying rollers 10 are arranged on the outer sides of the third rotating shafts 9. It also includes a single-chip microcomputer 2, which is arranged on the front side of the support frame 1. The input end of the single-chip microcomputer 2 is electrically connected to an external power supply. It also includes belt pulleys 11, which are all arranged at the lower ends of the third rotating shafts 9 at the rear side. The belt pulleys 11 are drivingly connected by a belt 12. On the upper side of the limit frame 7 at the rear side, there is a first motor 13. The input end of the first motor 13 is electrically connected to the output end of the single-chip microcomputer 2. The output shaft of the first motor 13 is fixedly connected to the upper end of the third rotating shaft 9 at the left rear end. It also includes a second motor 14, which is arranged on the front side of the connecting seat 5 at the front side. The input end of the second motor 14 is electrically connected to the output end of the single-chip microcomputer 2. The output shaft of the second motor 14 is fixedly connected to the front end of the bidirectional lead screw 6. Uniformly distributed guide rods 15 are arranged between the connecting seats 5. The limit frames 7 are all slidably connected to the guide rods 15. During the construction of the pigsty steel frame, the device is fixed to the designated position of the cutting machine. Then, the U-shaped steel is placed with the notch facing up above the longitudinal auxiliary rollers 4. Subsequently, the single-chip microcomputer 2 starts the second motor 14 so that its output shaft drives the bidirectional lead screw 6 to rotate. The bidirectional lead screw 6 makes the limit frames 7 move closer to the center part of the device through threaded connection. The limit frames 7 move longitudinally along the guide rods 15, thus avoiding the phenomenon of self-rotation during their longitudinal movement. The limit frames 7 drive the corresponding steel conveying rollers 10 to squeeze and fix the front and rear sides of the U-shaped steel. With the aid of the centering and limiting mechanism 8, centering extrusion and limiting of the U-shaped steel are achieved. Subsequently, the single-chip microcomputer 2 starts the first motor 13 so that its output shaft drives the third rotating shaft 9 at the left rear end to rotate. The third rotating shaft 9 drives the steel conveying rollers 10 at the rear side to rotate synchronously through the belt drive between the belt pulleys 11 and the belt 12. The steel conveying rollers 10 at the rear side automatically cut and convey the U-shaped steel through frictional contact. During this process, the longitudinal auxiliary rollers 4 adaptively rotate around the corresponding first rotating shafts 3 as the U-shaped steel is cut and moved. This U-shaped steel cutting frame can automatically perform centering and limiting and conveying of U-shaped steels of different models, avoid relative horizontal sliding between the U-shaped steel and the cutting frame, and thus improve the cutting accuracy of the U-shaped steel, which is convenient to use;

[0021] Limiting and centering mechanism 8: They are all arranged inside the limiting frame 7. The limiting and centering mechanism 8 includes pressure sensors 81, telescopic columns 82, longitudinal moving seats 84, second rotating shafts 85 and smooth rollers 86. The pressure sensors 81 are all arranged inside the limiting frame 7 and are all bidirectionally electrically connected to the single-chip microcomputer 2. Circular seats are provided on the sides of the pressure sensors 81 close to the center of the support frame 1. Longitudinal moving seats 84 are provided on the sides of the circular seats close to the center of the support frame 1 through the telescopic columns 82. Smooth rollers 86 are rotatably connected inside the longitudinal moving seats 84 through the second rotating shafts 85. The limiting and centering mechanism 8 further includes springs 83. The springs 83 are all arranged between the circular seats and the adjacent longitudinal moving seats 84 and are all movably sleeved on the outer ends of the adjacent telescopic columns 82. During this process, the single-chip microcomputer 2 activates the pressure sensors 81. The pressure sensors 81 perform longitudinal pressure detection on the circular seats and transmit the detection results to the single-chip microcomputer 2 in the form of electrical signals. As the limiting frame 7 moves longitudinally, the outer sides of the smooth rollers 86 first come into contact with the sides of the U-shaped steel. As the limiting frame 7 continues to approach the U-shaped steel, the smooth rollers 86 are pressed, the telescopic ends of the telescopic columns 82 and the springs 83 contract, and the pressure sensors 81 detect the pressure received by the circular seats and upload it. When the values measured by the front and rear two pressure sensors 81 are the same and reach a certain level, the single-chip microcomputer 2 shuts down the second motor 14. At this time, the U-shaped steel is cut and centered and fixed through the steel conveying rollers 10, enabling the device to perform cutting, centering and conveying on U-shaped steels of different models, which is convenient to use. The compression elastic force of the springs 83 facilitates the automatic reset of the smooth rollers 86 after the U-shaped steel is cut. By utilizing the change in the pressure indication of the pressure sensors 81, the device can automatically perform cutting, centering and limiting on the U-shaped steel.

[0022] The working principle of a U-shaped steel cutting rack provided by the utility model is as follows: During the construction of the pigsty steel frame, the device is fixed to the designated position of the cutting machine. Subsequently, the U-shaped steel is placed with the notch facing upwards above the longitudinal auxiliary roller 4. Then, the single-chip microcomputer 2 starts the second motor 14, and its output shaft drives the bidirectional lead screw 6 to rotate. The bidirectional lead screw 6 is connected by threads, so that the limit frame 7 moves towards the center part of the device. The limit frame 7 moves longitudinally along the guide rod 15, thus avoiding the phenomenon of self-rotation during its longitudinal movement. The limit frame 7 drives the corresponding steel conveying roller 10 to squeeze and fix the front and rear sides of the U-shaped steel. During this process, the single-chip microcomputer 2 starts the pressure sensor 81. The pressure sensor 81 detects the longitudinal pressure on the round seat and transmits the detection result to the single-chip microcomputer 2 in the form of an electrical signal. As the limit frame 7 moves longitudinally, the outer side of the smooth roller 86 first contacts the side of the U-shaped steel. As the limit frame 7 continues to approach the U-shaped steel, the smooth roller 86 is pressed, and the telescopic end of the telescopic column 82 and the spring 83 contract. The pressure sensor 81 detects the pressure received by the round seat and uploads it. When the values measured by the front and rear two pressure sensors 81 are the same and reach a certain level, the single-chip microcomputer 2 shuts down the second motor 14. At this time, the cutting and centering fixation of the U-shaped steel is realized through the steel conveying roller 10, enabling the device to perform cutting and centering transportation on U-shaped steels of different models, which is convenient to use. The compression elastic force of the spring 83 facilitates the automatic reset of the smooth roller 86 after the U-shaped steel is cut. Then, the single-chip microcomputer 2 starts the first motor 13, and its output shaft drives the third rotating shaft 9 at the left rear end to rotate. The third rotating shaft 9 drives the rear steel conveying roller 10 to rotate synchronously through the belt drive between the belt pulley 11 and the belt 12. The rear steel conveying roller 10 automatically performs cutting and transportation on the U-shaped steel through the contact friction force. During this process, the longitudinal auxiliary roller 4 adaptively rotates around the corresponding first rotating shaft 3 as the U-shaped steel is cut and moves.

[0023] It should be noted that in the above embodiments, the single-chip microcomputer 2 can adopt COP8CBE9, the pressure sensor 81 can adopt PCM303, and the first motor 13 and the second motor 14 can both adopt Y80M1-2. The single-chip microcomputer 2 controls the pressure sensor 81, the first motor 13, and the second motor 14 to work using the commonly used methods in the prior art.

[0024] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present utility model by the same token.
