Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Referring to Figures 1-5 , a discharging mechanism of a straightening machine, including a support frame 1, a material transporting assembly 2 is installed at the upper end of the support frame 1. The material transporting assembly 2 includes two mounting strips 21 installed at the upper end of the support frame 1. Mounting seats 22 are evenly screwed at the upper ends of the mounting strips 21. A rotating shaft 26 is rotatably connected between every two mounting seats 22. A reduction motor 24 is installed at the upper end of the support frame 1 through a mounting plate 23. A first gear 25 is installed at the output end of the reduction motor 24. A second gear 28 meshing with it is installed on the outer side of one of the rotating shafts 26. Double-layer pulleys 29 are installed on the outer sides of the rotating shafts 26. The double-layer pulleys 29 are sleeved with belts 210 with each other. Limiting guide wheels 27 are installed in the middle of the outer sides of the rotating shafts 26. A fixing cover 6 is installed at the upper end of the mounting plate 23. The reduction motor 24 is located inside the fixing cover 6.

[0023] The output end of the reduction motor 24 drives the first gear 25 to rotate, and the first gear 25 synchronously drives the second gear 28 and the rotating shaft 26 inside it to rotate. The double-layer pulley 29 on the outer side of this rotating shaft 26 drives the rotating shaft 26 with another double-layer pulley 29 installed through the belt 210. Similarly, the other rotating shafts 26 also rotate synchronously. Then the rotating shaft 26 drives the limiting guide wheel 27 to rotate. After the steel pipe is straightened by the straightening machine, it enters the upper ends of a plurality of limiting guide wheels 27. Since the shape of the limiting guide wheel 27 is high on both sides and low in the middle, the steel pipe is limited and transported, effectively improving the stability of its blanking and transportation. And through the design of the fixing cover 6 on the outer side of the reduction motor 24, it is convenient to effectively protect the reduction motor 24.

[0024] Measuring and positioning mechanisms 3 are installed on both sides of the support frame 1. The measuring and positioning mechanism 3 includes a support plate 31 installed on the outside of the support frame 1. A notch 32 is provided at the upper end of the support plate 31. Three groups of support seats 33 are provided at the upper end of the support plate 31. The support seats 33 are all screwed with nuts after bolts 34 pass through the notch 32. A first in-place sensor 35, a second in-place sensor 36, and a third in-place sensor 37 are respectively installed at the upper ends of the three support seats 33.

[0025] According to the size of the steel pipe to be cut, by shifting the support seats 33 at the lower ends of the second in-place sensor 36 and the third in-place sensor 37, the distance between the support seat 33 at the lower end of the second in-place sensor 36 and the support seats 33 at the lower ends of the first in-place sensor 35 and the third in-place sensor 37 is made the same. And all the support seats 33 are screwed and fixed by bolts 34 passing through the notch 32 and then screwing nuts, which is convenient for installation and disassembly, easy to adjust the position, effectively improves the use effect, and the heights of the first in-place sensor 35, the second in-place sensor 36, and the third in-place sensor 37 are higher than the mounting seat 22, avoiding blocking the first in-place sensor 35, the second in-place sensor 36, and the third in-place sensor 37 and affecting the use.

[0026] A cutting assembly 4 is installed at the upper end of the measuring and positioning mechanism 3. The cutting assembly 4 includes a fixed frame 41 installed at the upper ends of the two support plates 31. A first lifting cylinder 42 is installed at the upper end of the fixed frame 41. The output end of the first lifting cylinder 42 is connected to an L-shaped plate 43. A cutting machine 44 is installed inside the L-shaped plate 43. A cutting fluid pipe 45 is installed at the lower end of the L-shaped plate 43. The upper end of the cutting fluid pipe 45 penetrates the L-shaped plate 43 and is connected to a solenoid valve 46.

[0027] The measuring and positioning mechanism 3 measures and locates the position to be cut on the outside of the steel pipe. The output end of the first lifting cylinder 42 drives the L-shaped plate 43 and the cutting machine 44 to move downward, and the steel pipe is cut by starting the cutting machine 44. And during cutting, by connecting the cutting fluid pipe 45 to an external water supply device, the solenoid valve 46 is then opened, and water is sprayed through the cutting fluid pipe 45, which is convenient for cooling the blade of the cutting machine 44, improving the cutting effect and the service life of the cutting machine 44. And while the cutting machine 44 is cutting, the output end of the first lifting cylinder 42 continues to move downward slowly, which is convenient for completing the cutting.

[0028] A clamping mechanism 5 is installed on one side of the cutting assembly 4. The clamping mechanism 5 includes a top plate 51 installed on one side of the fixed frame 41. A second lifting cylinder 52 is installed at the upper end of the top plate 51. The output end of the second lifting cylinder 52 is connected to an arc-shaped pressing block 53. A leather pad 54 is bonded to the lower end of the arc-shaped pressing block 53. A connecting plate 55 is sleeved outside the output end of the second lifting cylinder 52. One side of the connecting plate 55 is connected to a connecting frame 56. Fixed plates 57 are symmetrically welded to the lower end of the connecting frame 56. An arc-shaped rubber plate 58 is bonded to the lower end of the fixed plate 57. A plurality of convex points are provided on the lower surface of the arc-shaped rubber plate 58.

[0029] The measuring and positioning mechanism 3 measures and locates the position that needs to be cut on the outer side of the steel pipe. By turning off the reduction motor 24, the operation of the material conveying assembly 2 is stopped. The output end of the second lifting cylinder 52 drives the arc-shaped pressing block 53 and the connecting plate 55 to move downward. Then the connecting plate 55 drives the fixed plate 57 to move downward synchronously through the connecting frame 56. Then the arc-shaped pressing block 53 presses against the upper surface of the steel pipe after moving downward, which is convenient for clamping it. And through the designed leather pad 54 in direct contact with the steel pipe, the friction force is increased, and then the pressing effect is enhanced. At the same time, the two fixed plates 57 drive the arc-shaped rubber plate 58 to press against the outside of the rotating shaft 26, which is convenient for stopping operation. And the convex points on the lower surface of the arc-shaped rubber plate 58 effectively increase the frictional resistance, and then enhance the stopping effect, avoiding the situation that after the arc-shaped rubber plate 58 clamps the steel pipe, the rotating shaft 26 drives the limiting guide wheel 27 to still rotate, affecting the fixing stability of the steel pipe and further affecting the flatness of the cutting surface of the steel pipe.

[0030] Working principle: The utility model is programmatically controlled and connected to a reduction motor 24, a first in-place sensor 35, a second in-place sensor 36, a third in-place sensor 37, a first lifting cylinder 42, a cutting machine 44, a solenoid valve 46, and a second lifting cylinder 52 through an external control terminal. When in use, according to the size of the steel pipe to be cut, the support seats 33 at the lower ends of the second in-place sensor 36 and the third in-place sensor 37 are displaced, so that the distance between the support seat 33 at the lower end of the second in-place sensor 36 and the support seats 33 at the lower ends of the first in-place sensor 35 and the third in-place sensor 37 is the same. All the support seats 33 are fixedly screwed by bolts 34 passing through the notch 32 and then screwing nuts, which is convenient for installation and disassembly and position adjustment, effectively improving the use effect. After the transporting component 2 transports the steel pipe straightened by the straightening machine for blanking, when the end of one end of the steel pipe is detected by the first in-place sensor 35, the length to be cut is measured. As the transporting component 2 continuously transports the steel pipe, when the end of one end of the steel pipe is detected by the second in-place sensor 36, the output end of the second lifting cylinder 52 of the clamping mechanism 5 drives the arc-shaped pressing block 53 and the connecting plate 55 to move downward. Then, the connecting plate 55 drives the fixing plate 57 to move downward synchronously through the connecting frame 56, facilitating the movement of the arc-shaped rubber plate 58 at the lower ends of the arc-shaped pressing block 53 and the fixing plate 57 above the steel pipe and the rotating shaft 56 for preparation, avoiding starting to move downward from a higher place and affecting the timely clamping effect. After statistical calculation based on the time between the first in-place sensor 35 and the second in-place sensor 36 of the steel pipe, when the steel pipe is about to move to the position of the third in-place sensor 37, the reduction motor 24 is turned off in advance. Since the reduction motor 24 has rotational inertia, it will still drive the transporting component 2 to operate for a very short time. The distance between the third in-place sensor 37 and the first in-place sensor 35 is the length of the steel pipe to be cut. Therefore, when the third in-place sensor 37 detects the end of the steel pipe, the transporting component 2 just stops operating. Upon receiving the start command from the control terminal at the same time, the output end of the second lifting cylinder 52 continues to move downward, driving the arc-shaped pressing block 53 and the connecting plate 55 to move downward simultaneously. As a result, the arc-shaped pressing block 53 presses against the upper surface of the steel pipe after moving downward, facilitating clamping pressure on it. The designed leather pad 54 is in direct contact with the steel pipe, increasing the friction force and thus enhancing the pressing effect. At the same time, the two fixing plates 57 drive the arc-shaped rubber plate 58 to press against the outside of the rotating shaft 26, facilitating the stopping operation. The convex points on the lower surface of the arc-shaped rubber plate 58 effectively increase the frictional resistance, further enhancing the stopping effect, preventing the rotating shaft 26 from driving the limit guide wheel 27 to rotate after the arc-shaped rubber plate 58 clamps the steel pipe, affecting the fixing stability of the steel pipe and thus the flatness of the cutting surface. Then, the output end of the first lifting cylinder 42 drives the L-shaped plate 43 and the cutting machine 44 to move downward, and the cutting machine 44 is started to cut the steel pipe. During cutting,Connect the cutting fluid pipe 45 to an external water supply device, then open the solenoid valve 46, and spray water through the cutting fluid pipe 45 to facilitate cooling the blade of the cutting machine 44, which is convenient for improving the cutting effect and the service life of the cutting machine 44. Moreover, while the cutting machine 44 is cutting, the output end of the first lifting cylinder 42 continues to slowly move downward to facilitate the completion of cutting.
