Description

Technical Field

At the same time, in the process of using the punching and cutting machine to cut the elliptical head, local stress concentration will occur at the cut, which may easily cause deformation and warping at the cut of the elliptical head, affecting the quality of the cut of the elliptical head. After the elliptical head is cut by the punching and cutting machine, burrs are easily formed on the outer wall of the cut of the elliptical head, and the burrs will affect the tightness of the subsequent process pipelines, instruments, etc. when connected to the elliptical head, greatly reducing the effect and reliability of the cut of the elliptical head.

[0036] Working principle of the present invention:

[0037] In the present invention, when it is necessary to make an incision on the elliptical head, the third electric slide rail 121 is first controlled to start, driving the third slide plate 122 to move, so that the distance between the multiple first U-shaped plates 123 and the midpoint of the bottom plate 1 is the same as the bottom radius of the elliptical head, and then the third motor 125 is controlled to start, driving the first round rod 124 to rotate, so that the inclination angle of the second U-shaped plate 126 matches the inclination angle of the side wall of the bottom opening of the elliptical head, and then the staff puts the bottom of the elliptical head that needs to be incised into the multiple second U-shaped plates 126, and then the second electric telescopic rod 127 is controlled to start, driving the clamping plate 128 to move toward the side wall of the elliptical head, and the elliptical head is fixed by the clamping plate 128, and then the second motor 5 is controlled to start, driving the second The gear 4 rotates, and during the rotation of the second gear 4, the first gear 3 meshing with the second gear 4 is driven to rotate, thereby driving the first fixed plate 61 to rotate, so that the punching and cutting machine 69 moves to the side where the elliptical head needs to be cut, and then the eighth motor 1015 is controlled to start, driving the fifth electric telescopic rod 101 to rotate, so that the opening on one side of the fourth U-shaped plate 102 corresponds to the position where the elliptical head needs to be cut, and then the sixth motor 106 is controlled to start, driving the third round rod 103 to rotate, so that the sixth electric telescopic rod 104 and the fourth fixed plate 105 face the position where the elliptical head needs to be cut, and then the fifth electric telescopic rod 101 is controlled to start, driving the fourth U-shaped plate 102 and the sixth electric telescopic rod 104 to move upward, so that the After driving the fourth fixed plate 105 to extend, the sixth electric telescopic rod 104 can face the position where the elliptical head needs to be cut. Then, the fifth electric slide rail 108 is controlled to start at the same time to drive the corresponding fifth slide plate 109 to move, so that the spacing between the four fifth slide plates 109 is slightly larger than the size of the cut required for the elliptical head. Then, the sixth electric telescopic rod 104 is controlled to start, driving the four support plates 1014 to move toward the inner wall of the elliptical head, and stopping when they are about to approach the inner wall of the elliptical head. Then, the four seventh motors 1012 are controlled to start at the same time to drive the fourth round rod 1011 to rotate, so that the inclination angle of the support plate 1014 matches the inclination angle of the corresponding inner wall of the elliptical head. Then, the seventh electric telescopic rod 1013 is controlled to start, driving the support plate 1014 Move toward the inner wall of the elliptical head, and use the support plate 1014 to support the elliptical head. At this time, the four support plates 1014 are respectively located on the four sides of the position where the elliptical head needs to be cut, so that the elliptical head generates an inward and outward supporting force to prevent the elliptical head from being deformed at the cut when the elliptical head is cut by the punching and cutting machine 69. After supporting the position where the inner wall of the elliptical head needs to be cut, control the first electric slide rail 62 to start, drive the first slide plate 63 to move, and move the second fixed plate 64 to make the punching and cutting machine 69 and the position where the elliptical head needs to be cut in the same plane. Then control the first electric telescopic rod 68 to start, drive the punching and cutting machine 69 to approach the side wall of the elliptical head, and punch and cut the outer wall of the elliptical head.The movement and rotation of the punching and notching machine 69 are realized by controlling the first electric slide rail 62, the second electric slide rail 65 and the first motor 67, so as to complete the incision of the elliptical head. Then, the third electric telescopic rod 73 is controlled to start, driving the third fixed plate 74 to move downward, so that the third fixed plate 74 is close to the top of the elliptical head. Then, the fourth motor 77 is controlled to start, driving the third fixed plate 74 and the third electric telescopic rod 73 to rotate, so that the third fixed plate 74 is located on one side of the elliptical head incision. Then, the third electric telescopic rod 73 is controlled to start, driving the third fixed plate 74 and the third electric telescopic rod 73 to rotate, so that the third fixed plate 74 is located on one side of the elliptical head incision. The fifth motor 712 is started to drive the second round rod 79 to rotate, so that the inclination angle of the fourth electric telescopic rod 710 matches the inclination angle of the outer wall at the elliptical head cutout. Then, the fourth electric telescopic rod 710 is controlled to start and drive the grinding plate 711 to move so that the grinding plate 711 and the elliptical head cutout are in the same plane. Then, the fourth electric slide rail 75 is controlled to start and drive the fourth slide plate 76 to move so that the grinding plate 711 conflicts with the outer wall at the elliptical head cutout. Then, the fourth motor 77 is controlled to drive the third electric telescopic rod 73 to reciprocate. The grinding plate 711 is moved back and forth at the cut of the elliptical head to grind the burrs at the cut of the elliptical head to prevent the burrs at the cut from affecting the connection between the elliptical head and the pipeline. The fixing assembly 12 can be used to fix elliptical heads of different sizes, and is suitable for elliptical heads with different bending angles. Then, the punching and cutting assembly 6 is used to automatically cut the elliptical head, avoiding the staff from cutting the elliptical head with a handheld punching and cutting machine 69, thereby reducing the efficiency of cutting the elliptical head. The support plate 1014 can also be used to fix the elliptical heads of different sizes and the elliptical heads of different sizes. The elliptical head is supported, so that the elliptical head generates an inward and outward supporting force, which prevents the elliptical head from being deformed when the punch cutter 69 is used to cut the elliptical head. At the same time, the grinding plate 711 can be adjusted to the same angle as the outer wall of the elliptical head cut, so that the burrs at the elliptical head cut can be polished by the grinding plate 711 to prevent the burrs from affecting the tightness of the subsequent process pipelines, instruments, etc. when connected to the elliptical head, which greatly improves the working efficiency and reliability of the device for the elliptical head cut.
