Description

Technical Field

[0001] This utility model belongs to the field of steel pipe processing technology, and in particular relates to a piercing device for processing seamless steel pipes. Background Technology

[0002] Seamless steel pipes are steel pipes formed by piercing a single round steel bar, with no weld seams on their surface. Based on the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and jacking pipes, etc. According to the cross-sectional shape, seamless steel pipes are divided into round and irregular shapes. Irregularly shaped pipes include square, oval, triangular, hexagonal, seed-shaped, star-shaped, and finned pipes, among other complex shapes. Seamless steel pipes are mainly used as drilling pipes for oil and geological processes, cracking pipes for petrochemicals, boiler tubes, bearing tubes, and high-precision structural steel pipes for automobiles, tractors, and aviation.

[0003] In the prior art, seamless steel pipes are made by piercing a whole round steel bar, and the surface is relatively smooth. This makes it easy for the piercing equipment to deviate in position when drilling, resulting in hole deviation, which is not convenient for subsequent piercing operations. Therefore, a piercing equipment for processing seamless steel pipes is proposed to solve the above problems. Utility Model Content

A second connecting shaft 209 is rotatably mounted inside the mounting frame 208. Friction guide wheels 210 are mounted on the circumferential side of the second connecting shaft 209, which facilitates the rotation of the position of the friction guide wheels 210 when drilling the steel pipe, so that the friction surface of the friction guide wheels 210 cross-contacts with the side of the steel pipe and fixes it by friction. In conjunction with the structure of the third electric push rod 304 and the curved positioning plate 305, the steel pipe is fixed on the conveying roller 104, which prevents the position of the steel pipe from deviating during drilling and improves the stability of drilling seamless steel pipe.

[0028] The first electric push rod 202 is electrically connected to the controller 4. A rotating rod 207 is slidably installed inside the guide groove 201. A limit plate 205 is welded to the other end of the rotating block 206.

[0029] The limiting plate 205 is rotatably installed inside the rotating sleeve 204. One end of the rotating rod 207 passes through the other surface of the mounting plate 203 and extends into the rotating sleeve 204. One end of the rotating rod 207 is fixedly connected to the limiting plate 205.

The two opening slots 102 are connected to the through holes 101. Several first couplings 103 are rotatably installed inside one opening slot 102.

[0032] A conveyor roller 104 is installed on the circumference of the first connecting shaft 103. The circumference of the conveyor roller 104 is in contact with the steel pipe.

[0034] Please see Figures 1-4 As shown, this utility model is a piercing device for processing seamless steel pipes. Its usage method is as follows: First, the seamless steel pipe is placed on the conveyor roller 104. Then, the piercing position is moved to below the drill rod 303. At this time, the controller 4 activates two third electric push rods 304. The third electric push rods 304 drive the curved positioning plate 305 to descend, causing the curved surface of the curved positioning plate 305 to contact and fix the seamless steel pipe. Then, the four rotating rods 207 are rotated 90 degrees. When the rotating rods 207 rotate, they drive the limiting plate 205 and the rotating block 206 to rotate. When the rotating block 206 rotates, it drives the mounting frame... The friction guide wheel 208 and the friction guide wheel 210 rotate, so that the friction surface of the friction guide wheel 210 is intersected with the seamless steel pipe. Then, the controller 4 starts the first electric push rod 202, which pushes the mounting plate 203 and the friction guide wheel 210 toward the seamless steel pipe, so that the friction guide wheel 210 contacts the side of the seamless steel pipe and rubs and fixes it. Then, the controller 4 starts the second electric push rod 301 to drive the drilling motor 302 to descend at a constant speed. At the same time, the controller 4 starts the drilling motor 302 to drive the drill rod 303 to rotate, drilling a hole in the seamless steel pipe.
