[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 3 The guide and locking device of the seamless steel pipe production punching machine includes a bracket 1, a rotating shaft 2, a guide plate 3, a connecting shaft 4, a transmission frame 5, a first mounting shaft 6, a connecting frame 7, a second mounting shaft 8, a sleeve 9, a cylinder 10 and a transmission shaft 11. The bracket 1 is an inverted "T"-shaped structure as a whole. Two groups of guide plates 3 are symmetrically rotated by the rotating shaft 2 below the bracket 1, and the two groups of guide plates 3 are symmetrically arranged in an "eight"-shaped structure, so that the two sides of the guide plates 3 can be locked by movement;

[0027] Further, considering the activity effect on both sides of the guide plate 3, a transmission frame 5 is connected to the outer end of the guide plate 3 through a connecting shaft 4. Specifically, the transmission frame 5 is arranged in a "Z"-shaped structure, and the bottom end of the transmission frame 5 is connected to the outer end of the guide plate 3 through the connecting shaft 4, and the transmission frame 5 is arranged obliquely, so that the transmission frame 5 drives the guide plate 3 to move through the connecting shaft 4. Considering the locking symmetry of the symmetrically arranged guide plate 3, two groups of transmission frames 5 are symmetrically arranged inside the bracket 1 to ensure the accuracy of the locking of the guide plate 3.

[0028] Reference Figure 1-Figure 3 In order to achieve stable movement of the transmission frame 5, the connecting shaft 4 is arranged below the transmission frame 5, and the connecting frame 7 is connected to the top of the transmission frame 5 through the first installation shaft 6, and the top of the connecting frame 7 is installed on the outside of the sleeve 9 through the second installation shaft 8. Through such an arrangement, the two ends of the connecting frame 7 are connected to the sleeve 9 and the transmission frame 5 through the second installation shaft 8 and the first installation shaft 6, respectively, so that the transmission frame 5 can rotate through the first installation shaft 6. In addition, considering the installation effect of the sleeve 9, the second installation shaft 8 is installed inside the bracket 1, so that the sleeve 9 can be fixedly installed inside the bracket 1, thereby achieving the stability of the connecting frame 7 during rotation;

[0029] Furthermore, considering the control of the rotation angle of the transmission frame 5 and the precise output, the output end of the cylinder 10 is provided through the inside of the sleeve 9, and the output end of the cylinder 10 is connected to the middle of the transmission frame 5 through the transmission shaft 11. Through such a configuration, the cylinder 10 can drive the transmission frame 5 to rotate through the transmission shaft 11 at the output end, so that the transmission frame 5 can drive the guide plate 3 to rotate through the connecting shaft 4 below. In order to realize the rotation of the symmetrically arranged guide plate 3, two groups of cylinders 10 are symmetrically fixed inside the bracket 1 to facilitate the synchronous and precise rotation of the two groups of guide plates 3. At the same time, considering the noise reduction effect on the working noise of the cylinder 10 inside the bracket 1, a hollow cavity is opened between the two groups of cylinders 10 in the bracket 1, which ensures the working stability and comfort of the device and is conducive to extending the service life of the device.

[0030] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
