Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe processing, in particular to an automatic perforating mechanism of a seamless steel pipe perforator. Background Art

[0002] Seamless steel pipe is a pipe produced by hot rolling or cold drawing. It has a smooth inner wall and uniform wall thickness. It has high strength, rigidity and corrosion resistance. The manufacturing process of seamless steel pipe does not contain welds, so its overall performance is more superior. It can be widely used in many fields such as petroleum, chemical industry, construction, transportation, energy, etc.

[0003] In the process of producing seamless steel pipes, it is necessary to perform a perforation operation on the seamless steel pipe embryo that has been heated to a specified temperature. However, during the perforation process, a perforating push rod needs to be used to impact and insert into the seamless steel pipe embryo to achieve the effect of preliminary processing of the embryo structure. When the perforating push rod impacts the seamless steel pipe embryo, a certain vibration will be generated. The influence of the vibration may cause the position of the perforating push rod to shift, resulting in a worse perforation effect. In addition, the existing seamless steel pipe perforating machine cannot easily replace the perforating push rod, and the perforating push rod that cannot change the circumferential diameter has a greater impact on the subsequent seamless steel pipe manufacturing operations. For requirements for thin pipe walls, a thicker circumferential diameter perforating push rod is required for perforation operations to reduce subsequent grinding and processing operations. The existing seamless steel pipe perforating machine cannot easily replace the perforating push rod, and has low work efficiency and practicality. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, a push rod mechanism is provided. By using the push rod mechanism, the perforating push rod can maintain a precise position when hitting the seamless steel pipe blank, avoiding the offset problem caused by vibration, thereby improving the accuracy of perforation. The push rod mechanism allows for rapid replacement of the perforating push rod, so that the equipment can adapt to the production of seamless steel pipes with different diameters and thin-wall requirements, thereby improving the flexibility and adaptability of the equipment.

The double-end limiting structure limits the movement range of the punching push rod, avoiding the problem of poor punching effect due to the displacement of the push rod position, thereby improving the accuracy of the punching; the limiting mechanism ensures the safety of the punching operation, avoiding equipment damage or personal safety accidents due to movement out of range, and the limiting mechanism provides precise guidance for the punching operation, so that the operator can perform punching according to the predetermined trajectory, thereby optimizing the process of the punching operation.

[0028] The perforating push rod 407 is used to impact the seamless steel tube embryo 2 to achieve the effect of preliminary processing of the embryo structure. The hydraulic cylinder 403 provides power to drive the perforating push rod 407 to perform an impact action. The hydraulic push rod 404 connects the hydraulic cylinder 403 and the perforating push rod 407 to transmit power.
