Description

Technical Field

[0001] The invention relates to the technical field of steel pipe processing, in particular to a seamless steel pipe processing and straightening device. Background Art

[0002] Seamless steel pipe is a steel pipe with no weld seams on the surface, which is made by punching a whole round steel bar. In the processing of seamless steel pipe, straightening is a very important step, which is used to correct the bending of the steel pipe during manufacturing or transportation to ensure the quality of the seamless steel pipe. Seamless steel pipe is generally straightened by an inclined roller straightening machine. During the straightening process, the seamless steel pipe moves forward while rotating axially, that is, it makes a spiral forward motion.

[0003] Since there is a certain curvature in the seamless steel pipe before straightening, the part of the seamless steel pipe that has not entered the straightening machine will swing during the rotation of the seamless steel pipe, which will affect the stability of the straightening of the steel pipe; secondly, when the right end of the seamless steel pipe comes out of the straightening machine, it is only supported by the support roller. Since the left end of the seamless steel pipe is still being straightened in the straightening machine, the straightening machine will continue to exert force on the seamless steel pipe. The force is transmitted to the right with the seamless steel pipe, which will affect the stability of the right end of the seamless steel pipe, and then affect the overall straightening effect of the seamless steel pipe.

A pressing roller is rotatably installed inside the roller frame 25. The top roller frame 25 is movably connected to the stabilizing block 22, and the other roller frames 25 are fixedly connected to the inner wall of the through hole. A triangular connecting component 26 is connected between the plurality of roller frames 25, and an offset component 27 for driving the top roller frame 25 to move is installed on the stabilizing block 22. It should be noted that the lead screw linear drive module is an existing structure, and the lead screw linear drive module drives the stabilizing block 22 on the left to move horizontally and linearly to the right or left.

[0036] See also Figure 1 and Fig. 9 The straightening mechanism 3 includes a support platform 31 installed on the right side of the straightening mechanism 1, and a plurality of support rollers 32 equidistantly distributed on the left and right sides are rotatably installed on the top of the support platform 31. A straightening component 33 for clamping and straightening the steel pipe and a locking component 34 for locking the straightening component 33 are installed on the top of the support platform 31. A conveying component 35 for driving the straightening component 33 and the locking component 34 to separate is installed on the support platform 31.

[0037] See also Figure 1 and Figure 2 The straightening mechanism 1 includes a processing table 11 fixedly installed between a slide 21 and a support table 31, a gantry 12 is fixedly installed on the top of the processing table 11, and a plurality of slanted rollers 13 equidistantly distributed on the left and right are rotatably installed on the top of the processing table 11 and the bottom of the horizontal section of the gantry 12, and the two slanted rollers 13 facing each other up and down are distributed in a cross shape, and two multi-axis motors 14 distributed on the left and right are arranged behind the processing table 11, and the plurality of conveying shafts of the left multi-axis motor 14 are coaxially connected to the plurality of slanted rollers 13 above, and the plurality of output shafts of the right multi-axis motor 14 are coaxially connected to the plurality of slanted rollers 13 below, and the slanted rollers 13 are dumbbell-shaped. It should be noted that the straightening mechanism 1 in the present invention is the existing slanted roller straightening machine.

[0038] When in use, the seamless steel pipe passes between the two corresponding upper and lower inclined rollers 13, and the inclined rollers 13 are pressed tightly on the upper and lower sides of the seamless steel pipe. The multi-axis motor 14 is used to drive the corresponding inclined rollers 13 to rotate, so that the inclined rollers 13 drive the seamless steel pipe to move to the right and rotate continuously, and the seamless steel pipe is straightened by the rolling fit of the upper and lower inclined rollers 13.

[0039] See also Figure 1 and Figure 3 The guide assembly 24 includes a fixed plate 241 which is fixedly connected to the top of the slide 21 and is symmetrically distributed on the left and right sides. A circular hole with the same size and coaxial line as the through hole is opened in the middle of the fixed plate 241. The left and right stabilizing blocks 22 are located between the left and right fixed plates 241. A guide rod 242 which is symmetrically distributed front and back is fixedly connected between the left and right fixed plates 241. The left stabilizing block 22 is slidably installed between the front and rear guide rods 242, and the right stabilizing block 22 is fixedly connected between the front and rear guide rods 242.

[0040] When in use, the seamless steel pipe is placed between the left and right stabilizing blocks 22, the axis of the seamless steel pipe coincides with the axis of the through hole, and the two ends of the seamless steel pipe are clamped by the clamping rollers in the roller frame 25, wherein the clamping degree of the seamless steel pipe by the left clamping roller is greater than that of the right clamping roller. Then, the left stabilizing block 22 is driven to move rightward by the left and right moving components 23, so that the right end of the seamless steel pipe enters between the upper and lower inclined rollers 13 for straightening, and the unstraightened part of the seamless steel pipe is clamped by the clamping roller to avoid the seamless steel pipe from swinging during the straightening process, thereby improving the stability of the straightening of the seamless steel pipe.

[0041] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 The number of roller frames 25 is three and the two lower roller frames 25 are symmetrically distributed front to back. The triangular connecting assembly 26 includes a triangular connecting frame 261 that is connected together on one side of the three roller frames 25 away from the center of the slide 21. The two lower roller frames 25 are fixedly connected to the triangular connecting frame 261. The uppermost roller frame 25 is movably connected to the triangular connecting frame 261. A card slot 262 is provided on the top of the triangular connecting frame 261 near the uppermost roller frame 25. A positioning block 251 that matches the card slot 262 is integrally formed on the side of the uppermost roller frame 25 near the corresponding triangular connecting assembly 26. A wedge block 263 located above the positioning block 251 is slidably installed inside the card slot 262. A reset spring 264 is fixedly connected between the side of the wedge block 263 away from the corresponding roller frame 25 and the inner wall of the triangular connecting frame 261. An unlocking component 265 that drives the wedge block 263 to unlock is also installed on the triangular connecting frame 261.

[0042] In the initial state, the top roller frame 25 is located above the triangular connecting frame 261 and on the side away from the center of the slide 21. The seamless steel pipe is placed on the clamping rollers in the two roller frames 25 below. Then the offset component 27 first drives the top roller frame 25 to move above the two roller frames 25 below, and then drives the top roller frame 25 to move downward to clamp the seamless steel pipe. When the top clamping roller clamps the seamless steel pipe, the positioning block 251 is just inserted into the slot 262. When the left and right moving components 23 drive the left stabilizing block 22 to move to the right, the wedge block 263 moves to the left, so that the wedge block 263 blocks the top of the positioning block 251, and locks the roller frame 25 and the triangular connecting frame 261 together. The three roller frames 25 form a triangular structure, which improves the stability of the fixation of the seamless steel pipe and prevents the positioning block 251 from detaching from the slot 262.

[0043] See also Figure 5 and Figure 6 The unlocking component 265 includes a first gear 2651 rotatably mounted inside the triangular connecting frame 261 and located below the wedge block 263. The first gear 2651 is meshed with first racks 2652 on both the upper and lower sides. The upper end of the first rack 2652 close to the roller frame 25 is fixedly connected to the bottom of the wedge block 263. The lower end of the first rack 2652 close to the roller frame 25 is fixedly connected to the inner wall of the triangular connecting frame 261 with a return spring 2653, and the end away from the roller frame 25 slides through the outside of the triangular connecting frame 261.

[0044] When the wedge block 263 is to release the lock on the positioning block 251, the first rack 2652 below is pushed to move toward the roller frame 25, and then the first rack 2652 below drives the first gear 2651 to rotate, and then the first gear 2651 drives the first rack 2652 above and the wedge block 263 to move away from the roller frame 25, so that the wedge block 263 retracts into the interior of the triangular connecting frame 261 and no longer blocks the positioning block 251, thereby releasing the lock on the roller frame 25.

[0045] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7The top of the stabilizing block 22 is provided with a movable groove for the uppermost roller frame 25 to move up and down and left and right. The offset assembly 27 includes an electric push rod 271 fixedly connected to the side of the stabilizing block 22 away from the center of the slide 21. The side of the telescopic section of the electric push rod 271 close to the center of the slide 21 extends to the movable groove and is fixedly connected to a U-shaped frame 272. The top of the uppermost roller frame 25 is fixedly connected to a movable block 273. Two parallel inclined grooves 2731 are provided inside the movable block 273. The inclined grooves 2731 are close to the movable grooves 2731. One end of the center of the slide 21 is tilted upward, and two cylinders 2721 distributed up and down are fixedly connected between the two parallel sections of the C-shaped frame 272. The cylinder 2721 is slidably installed inside the corresponding inclined groove 2731. A blocking piece 274 located on the side of the movable block 273 close to the center of the slide 21 is fixedly connected between the front and rear side walls of the movable groove. A connecting block 275 is fixedly connected to the bottom of the horizontal section of the C-shaped frame 272, and a return spring 276 parallel to the inclined groove 2731 is fixedly connected between the movable block 273 and the connecting block 275.

[0046] When the seamless steel pipe is placed on the two clamping rollers below, the movable block 273 and the upper roller frame 25 are pushed by the electric push rod 271 to move toward the center of the slide 21. When the movable block 273 contacts the baffle 274, the movable block 273 no longer moves toward the center of the slide 21. At this time, the upper roller frame 25 just moves to the top of the two roller frames 25 below. Then the electric push rod 271 pushes the lower roller frame 272 to continue to move toward the center of the slide 21. At this time, the cylinder 2721 will slide along the inclined groove 2731, and the reset spring 276 will be compressed at the same time. The movable block 273 and the roller frame 25 are pushed downward by the cylinder 2721, so that the uppermost clamping roller is pressed against the top of the seamless steel pipe.

[0047] When the top roller frame 25 is to be moved away, the electric push rod 271 drives the shaped frame 272 to move away from the center of the slide 21. At this time, the cylinder 2721 moves in the opposite direction along the inclined groove 2731, and the movable block 273 is pushed upward by the rebound force of the reset spring 3 276. When the top clamping roller moves to the top of the triangular connecting frame 261, the cylinder 2721 just moves to the bottom end of the inclined groove 2731, and then the electric push rod 271 drives the shaped frame 272 to continue to move away from the slide 21. At this time, the shaped frame 272 drives the movable block 273 to move together in the direction away from the center of the slide 21, and the top roller frame 25 is moved away from the two roller frames 25 below to avoid affecting the placement of the seamless steel pipe on the two roller frames 25 below.

[0048] See also Figure 1 , Figure 3 , Figure 6 and Figure 8 The unlocking drive assembly 28 includes a shell 281 fixedly connected between the front sides of the left and right fixed plates 241, and the inside of the shell 281 is rotatably connected to the second gear 282 at one end close to the left fixed plate 241, and the second gear 282 is meshed with a second rack 283 on both the front and rear sides, and the second rack 283 is slidably connected to the shell 281 left and right, and the second rack 283 slides through the outer side of the shell 281 at one end close to the corresponding fixed plate 241 and is fixedly connected to a movable rod 284, and the movable rod 284 is fixedly connected to the end away from the shell 281. The pushing rod 285 is located on the side of the first rack 2652 away from the center of the slide 21, and the top of the second gear 282 is coaxially rotatably connected to a synchronous gear 286 located above the shell 281, and the front side of the left stabilizing block 22 is fixedly connected to a driving rack 287 meshing with the synchronous gear 286.

[0049] When the left-right moving assembly 23 drives the left stabilizing block 22 to move rightward, the stabilizing block 22 drives the driving rack 287 to move rightward, and the driving rack 287 drives the synchronous gear 286 and the second gear 282 to rotate clockwise, and then the second gear 282 drives the front and rear second racks 283 to move outward in opposite directions, and then the second rack 283 pushes the movable rod 284 and the pushing rod 285 away from the first rack 2652. At this time, the rebound force of the return spring 2653 is used to push the first rack 2652 to move away from the center of the slide 21. At the same time, the return spring 1 264 pushes the wedge block 263 to move toward the center of the slide 21, so that the wedge block 263 presses the positioning block 251 to lock the roller frame 1 25.

[0050] When the left-right moving assembly 23 drives the left stabilizing block 22 to move left to the left end of the slide 21, the driving rack 287 meshes with the synchronous gear 286 and drives the synchronous gear 286 and the second gear 282 to rotate counterclockwise, and then the second gear 282 drives the front and rear second racks 283 to move toward each other. At this time, the second rack 283 drives the movable rod 284 and the pushing rod 285 to move toward the center of the slide 21, and finally the pushing rod 285 presses the first rack 2652, so that the wedge block 263 releases the lock on the positioning block 251.
