Abstract
The invention relates to the technical field of seamless steel tube production equipment, in particular to a perforating machine for producing a seamless steel tube. The perforating machine comprises an upper roller positioned on the upper surface of the seamless steel tube, a lower roller positioned on the lower surface of the seamless steel tube, a front guide disc positioned on the front surface of the seamless steel tube and a rear guide disc positioned on the rear surface of the seamless steel tube, wherein the upper roller and the lower roller are arranged in a mirror image mode, and the front guide disc and the rear guide disc are arranged in the mirror image mode; a perforating mechanism is inserted in a cavity on the right side of the seamless steel tube, the perforating mechanism comprises a top rod for applying pressure to the perforating mechanism by a pressure mechanism, a top head is fixedly mounted at the left end of the top rod, and a chip removal gap is formed between the perforating mechanism and the cavity on the right side of the seamless steel tube. The perforating machine for producing the seamless steel tube is compact in structure and high in perforating efficiency, and the inner bore shape and size of the obtained seamless steel tube meet the technological requirements.
Description
Technical field
The present invention relates to the technical field of seamless steel pipe production, especially a kind of production seamless steel pipe punch.
Background technology
Seamless steel pipe has hollow section, and a large amount of pipeline being used as conveying fluid, as transfer oil, natural gas, coal gas, water and some solid material etc.Seamless steel pipe compared with the solid steel such as round steel, under identical bending resistance torsional strength, the lighter in weight of seamless steel pipe; Meanwhile, seamless steel pipe is also widely used in manufacturing structure part and machine components, and as the steel scaffold etc. in oil drill rocker, truck drive shaft, bicycle rack and construction, stock utilization is high, and manufacturing process is simple and easy, and machining period reduces.
Just because of the particularity of seamless steel pipe purposes, therefore, need to use various production equipment in the production process of seamless steel pipe, punch is exactly produce one very important in seamless steel pipe equipment, but, existing most of punch complicated structure, maintenance cost is high, and the shape and size of perforation can not meet technological requirement; Meanwhile, usually there is the phenomenon blocked when boring a hole, having had a strong impact on the efficiency of perforation.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the prior art Problems existing in above-mentioned background technology, there is provided a kind of and produce seamless steel pipe punch, compact conformation, piercing efficiency is high, and internal via shape and the size of gained seamless steel pipe all meet technological requirement.
The technical solution adopted for the present invention to solve the technical problems is: a kind of production seamless steel pipe punch, there is the topping roll being positioned at seamless steel pipe upper surface, the bottom roll being positioned at seamless steel pipe lower surface, be positioned at the front godet of seamless steel pipe front surface and be positioned at the rear godet of seamless steel pipe rear surface, described topping roll and bottom roll mirror image are arranged, and described front godet and rear godet mirror image are arranged; Be inserted with punch block mechanism in cavity on the right side of seamless steel pipe, described punch block mechanism comprises by the push rod of pressure mechanism to its pressure of exerting pressure, and the left end of described push rod is installed with top, leaves burr and chip clearance between the cavity on the right side of punch block mechanism and seamless steel pipe.
The smooth perforation of punch block mechanism can be assisted well for the ease of topping roll, bottom roll, front godet and rear godet, therefore described topping roll and bottom roll distribute with seamless steel pipe circumcircle respectively, described front godet and rear godet distribute with seamless steel pipe inscribed circle respectively.
For the ease of discharging because of the scrap stayed of boring a hole timely, therefore the end cross-sectional area of described push rod is less than the end cross-sectional area of top.
Penetrate the inner chamber of seamless steel pipe fast for the ease of ailhead, therefore the longitudinal cross-section shape of described top is isosceles trapezoid, two waists of isosceles trapezoid are that mirror image is arranged and all outwardly circular arc formation.
Further specifically, described topping roll and bottom roll reversely rotate.
The invention has the beneficial effects as follows: production seamless steel pipe punch of the present invention, compact conformation, reasonable in design, easy to maintenance, piercing efficiency is high, and internal via shape and the size of gained seamless steel pipe all meet technological requirement, can be widely used in the producer of various production seamless steel pipe.
