Description

Technical Field

[0001] This utility model belongs to the field of stainless steel pipe processing technology, specifically a horizontal multi-roller precision straightening machine for stainless steel pipes. Background Technology

[0002] The horizontal multi-roll precision straightener for stainless steel pipes is a specialized piece of equipment designed to meet the straightening needs of stainless steel pipes. The equipment uses multiple sets of straightening rollers arranged in an alternating pattern to form continuous straightening units. The more rollers there are, the denser the straightening points, and the more precise the bending control of the pipe. For example, a 23-roll straightener can achieve uniform plastic elongation of the pipe across its entire thickness and eliminate internal stress through alternating forward and reverse bending of small-diameter work rollers.

[0003] Existing multi-roller precision straightening machines typically straighten stainless steel tubes of different sizes by individually adjusting and clamping multiple rolls. This operation is not only cumbersome and complex, but also greatly reduces the efficiency of continuous processing. Therefore, it is necessary to improve the machine. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 7 As shown, this utility model provides a horizontal multi-roller precision straightening machine for stainless steel pipes, including a processing table 1. A first straightening roller group 2 is slidably installed on both sides of the top of the processing table 1. The bottom end of the first straightening roller group 2 extends into the interior of the processing table 1. A connecting plate 3 is provided between the front and rear ends of both sides of the first straightening roller group 2. A limit frame 4 is provided at the bottom of the middle of the connecting plate 3. The bottom end of the limit frame 4 extends into the interior of the processing table 1. A sliding plate 5 is provided at the inner end of the limit frame 4. A first limit rod 6 is provided in the inner groove of the sliding plate 5. A sliding block 7 is slidably connected to the surface of the first limit rod 6. A drive motor 8 is provided inside the processing table 1, located below the middle of the inner end of the sliding plate 5. A drive shaft 9 is fixedly sleeved at the top output end of the drive motor 8. A rotating plate 10 is fixedly sleeved at the top end of the drive shaft 9. The two ends of the rotating plate 10 are hinged to the inner side of the sliding block 7.

[0017] By starting the drive motor 8, the drive shaft 9 at the output end can be rotated, which in turn drives the rotating plate 10 to rotate. This causes the sliding blocks 7 at both ends of the rotating plate 10 to slide in the inner groove of the sliding plate 5, which can smoothly drive the two first limit rods 6, the sliding plate 5, the limit frame 4 and the connecting plate 3 to move in opposite directions or away from each other.

[0018] like Figures 5 to 7 As shown, the size of the sliding block 7 is adapted to the size of the inner groove of the sliding plate 5, and the surface of the sliding block 7 is slidably connected to the surface of the inner groove of the sliding plate 5.

[0019] By adopting the above scheme, through the matching of the inner groove of the sliding plate 5 with the size of the sliding block 7 and the design of the first limiting rod 6, a good limiting effect can be achieved for the sliding block 7 when it slides inside the sliding plate 5.

[0020] like Figure 1 and Figure 7As shown, a second straightening roller group 11 is provided in the middle of the top of the processing table 1, and a second limiting rod 12 is slidably connected to both sides inside the second straightening roller group 11. There are two second limiting rods 12, and the top of each of the two second limiting rods 12 is fixedly connected to a third straightening roller group 13.

[0021] By adopting the above scheme, the design of two second limiting rods 12 can make the third straightening roller group 13 move up and down smoothly, thereby achieving the effect of limiting the up and down movement of the third straightening roller group 13.

[0022] like Figure 3 and Figure 4 As shown, a trapezoidal plate 14 is provided at the bottom of the middle part of the back side of the third straightening roller group 13, and there are two trapezoidal plates 14. A fixing plate 15 is provided at the middle of the top end of the connecting plate 3. The top end of the fixing plate 15 extends to the inner side of the two trapezoidal plates 14, and the outer side of the top of the fixing plate 15 is slidably connected to the inner side of the two trapezoidal plates 14.

[0023] By adopting the above scheme, the design of two trapezoidal plates 14 can achieve the effect of fitting and limiting the sliding of the top part of the fixed plate 15 located inside the trapezoidal plate 14.

[0024] like Figure 4 As shown, a linkage shaft 16 is provided inside the top of the fixed plate 15. The outer end of the linkage shaft 16 extends into the inclined groove of the trapezoidal plate 14, and the outer end of the linkage shaft 16 is slidably connected to the inclined groove of the trapezoidal plate 14.

[0025] By adopting the above scheme, when the connecting plate 3 at the rear end is driven to move back and forth, the fixed plate 15 will move synchronously, thereby causing the outer end of the linkage shaft 16 at the top of the fixed plate 15 to slide along the inclined groove of the trapezoidal plate 14, so that the extrusion drives the trapezoidal plate 14 and the third straightening roller group 13 to move up and down in the horizontal direction.

[0026] Working principle and usage process of this utility model: First, the operator can place the steel pipe on one side of the first straightening roller group 2, and then the pipe is straightened and transported between the second straightening roller group 11 and the third straightening roller group 13 by the operation of the first straightening roller group 2 for straightening on the other two sides. Then, it is straightened and transported out by the first straightening roller group 2 on the other side, thus completing the straightening operation of the stainless steel pipe.

[0027] Then, when it is necessary to straighten stainless steel pipes of different sizes, the drive motor 8 can be started first, so that the drive shaft 9 at the output end of the drive motor 8 rotates, which in turn drives the rotating plate 10 to rotate. At this time, the rotation of the rotating plate 10 will pull the sliding blocks 7 hinged at both ends to slide along the surface of the first limiting rod 6 in the inner groove of the sliding plate 5, so as to drive the two sliding plates 5, the limiting frame 4, the connecting plate 3 and the first straightening roller group 2 to move towards or away from each other. At the same time, when the connecting plate 3 at the rear end moves, it can drive the top of the connecting plate 3 at the rear end. The outer end of the linkage shaft 16 inside the top of the fixed plate 15 at the middle of the end slides along the inclined groove inside the trapezoidal plate 14, thereby driving the trapezoidal plate 14 and the third straightening roller group 13 to move up and down as a whole. That is, when the two connecting plates 3 and the first straightening roller group 2 move in opposite directions, the trapezoidal plate 14 and the third straightening roller group 13 move upward as a whole, and when the two connecting plates 3 and the first straightening roller group 2 move towards each other, the trapezoidal plate 14 and the third straightening roller group 13 move downward as a whole. Ultimately, the purpose of straightening stainless steel pipes of different diameters can be achieved.
