Description

Technical Field

[0001] The utility model relates to the technical field of high-speed wire equipment, in particular to a laying pipe locking device with adjustable gap. Background Art

[0002] Currently, the vast majority of wire rod mills use American Morgan or domestically produced Morgan-like laying heads to roll high-speed wire rod. The laying head is a core piece of equipment in high-speed wire rod mills and is equipped with a vibration alarm. The vibration level of the laying head directly affects the production efficiency of high-speed wire rod. When rolling small gauges in a workshop, the finished product line speed is set high. When it reaches or exceeds 100 m / s, the laying head experiences unstable vibration and imbalance, resulting in multiple alarm stops. This can lead to premature equipment damage, increased frequency of laying tube replacement, unstable laying coils, and poor packaging quality. After dynamic balancing tests and adjustments, the vibration level remains stable for a period of time, but over time, the unstable vibration and imbalance reappear. Investigations have revealed that a key factor contributing to the imbalance is an excessive gap between the laying head clamp and the laying tube. This looseness of the clamp can cause the clamp to shift position during speed increases or decreases, resulting in high vibration during high-speed operation.

[0003] The traditional tube clamp pin is designed with concentric circles. The distance between the spinning tube and the tube clamp cannot be adjusted. This gap is highly dependent on the manufacturing accuracy of the spinning head bracket, tube clamp, and spinning tube. The tube clamp may be too tight or too loose. If it is too tight, the tube clamp pin cannot be inserted. If it is too loose, the tube clamp will loosen. Utility Model Content

[0048] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] Example

[0050] like Figures 1 to 5 The embodiment of the spinning pipe locking device with an adjustable gap is shown, which is suitable for abutting the fixing block 19 on the spinning head and the spinning pipe 20, including:

[0051] U-shaped pipe clamp 1;

[0052] A pipe clamp pin 2 is rotatably mounted on the U-shaped pipe clamp 1;

[0053] A positioning assembly, adapted to fix the pipe clamp pin 2 on the U-shaped pipe clamp 1;

[0054] The pipe clamp pin 2 is provided with an eccentric ring 3, which is located between the two arms of the U-shaped pipe clamp 1 and extends through the inner side of the fixed block 19. The spinning tube 20 is provided between the bottom end of the U-shaped pipe clamp 1 and the fixed block 19. Rotating the pipe clamp pin 2 is suitable for adjusting the distance between the eccentric ring 3 and the bottom end of the U-shaped pipe clamp 1 so that the fixed block 19 and the spinning tube 20 abut. The spinning tube 20 can be arranged on the spinning head according to the Archimedean spiral and abut the fixed block 19 on the spinning head.

[0055] By rotating the pipe clamp pin 2 and adjusting the distance between the eccentric ring 3 and the bottom end of the U-shaped pipe clamp 1 until the fixing block 19 and the spinning pipe 20 abut against each other, the spinning pipe 20 can be locked on the fixing block 19.

[0056] Specifically, the positioning assembly can be a threaded rod that passes through the side of the pipe clamp pin 2 and the support arm of the U-shaped pipe clamp 1 and is screwed to the pipe clamp pin 2 and the U-shaped pipe clamp 1 respectively, so that the pipe clamp pin 2 and the U-shaped pipe clamp 1 are fixedly connected.

[0057] Furthermore, the U-shaped pipe clamp 1 includes a first arm 4 and a second arm 5, and the spinning pipe is arranged at the bottom end of the connection between the first arm 4 and the second arm 5. When the spinning pipe is locked, the spinning pipe abuts against the connection between the first arm 4 and the second arm 5, the first arm 4, the second arm 5, and the eccentric ring 3.

[0058] Furthermore, the first arm 4 is provided with a first adjustment through hole 6 , the second arm 5 is provided with a second adjustment through hole 7 , and the pipe clamp pin 2 is rotatably disposed in the first adjustment through hole 6 and the second adjustment through hole 7 .

[0059] The first adjusting through hole 6 and the second adjusting through hole 7 can limit the pipe clamp pin 2 in the radial direction.

[0060] Furthermore, the pipe clamp pin 2 includes:

[0061] A first adjustment ring 8 is provided on the first support arm 4 on a side away from the second support arm 5. The diameter of the first adjustment ring 8 is larger than the diameter of the first adjustment hole 6 so that the first adjustment ring 8 does not pass through the first adjustment hole 6. By fixing the first adjustment ring 8 to the first support arm 4, the entire pipe clamp pin 2 can be fixed to the U-shaped pipe clamp 1;

[0062] The eccentric ring 3 is arranged between the first support arm 4 and the second support arm 5;

[0063] The second adjustment ring 9 is rotatably arranged in the second adjustment through hole 7 ; the second adjustment ring 9 and the second adjustment through hole 7 can be clearance-fitted to facilitate the rotation of the second adjustment ring 9 in the second adjustment through hole 7 .

[0064] The eccentric ring 3 is connected and arranged between the first adjustment ring 8 and the second adjustment ring 9. The central axis of the eccentric ring 3 is eccentric relative to the central axis of the first adjustment ring 8 and the second adjustment ring 9. The distance between the eccentric ring 3 and the middle position of the U-shaped pipe clamp 1 can be adjusted between two eccentric distances.

[0065] The eccentric position of the eccentric ring 3 can be adjusted by rotating the first adjusting ring 8 , thereby adjusting the distance between the eccentric ring 3 and the middle position of the U-shaped pipe clamp 1 .

[0066] Furthermore, a third adjustment ring 10 is provided between the first adjustment ring 8 and the eccentric ring 3. The third adjustment ring 10 is provided inside the first adjustment hole 6. The third adjustment ring 10 can be loosely fitted with the first adjustment hole 6 to facilitate relative rotation between the third adjustment ring 10 and the first adjustment hole 6. The third adjustment ring 10 can make the eccentric position of the eccentric ring 3 more stable when being adjusted.

[0067] Furthermore, the central axes of the first adjustment ring 8 , the second adjustment ring 9 and the third adjustment ring 10 coincide with each other.

[0068] Furthermore, the positioning component includes:

[0069] A first positioning through hole 11 is formed in the middle of the first adjustment ring 8, the second adjustment ring 9, the eccentric ring 3, and the third adjustment ring 10, and the first positioning through hole 11 coincides with the central axes of the first adjustment ring 8, the second adjustment ring 9, and the third adjustment ring 10, respectively;

[0070] a positioning bolt 12, wherein the nut of the positioning bolt 12 is located on a side of the first adjustment ring 8 away from the first support arm 4, and the screw rod of the positioning bolt 12 is located in the first positioning through hole 11 and passes through the second support arm 5 to the outside of the second support arm 5;

[0071] The positioning nut 13 is fixedly disposed on the end side of the second arm 5 away from the first arm 4 and aligned with the second adjustment through hole 7 . The positioning bolt 12 passes through the second adjustment through hole 7 and is threadedly connected to the positioning nut 13 .

[0072] It should be noted that the nut of the positioning bolt 12 can be made larger than the diameter of the first positioning through-hole 11 so that the nut of the positioning bolt 12 and the positioning nut 13 can clamp the pipe clamp pin 2 to the first support arm 4 and the second support arm 5. Washers can also be added to the nut of the positioning bolt 12. Tightening the positioning bolt 12 can fix the first adjustment ring 8 to the first support arm 4.

[0073] After the eccentric position of the eccentric ring 3 is adjusted, the pipe clamp pin 2 can be fixed to the first support arm 4 and the second support arm 5 by tightening the positioning bolt 12 .

[0074] Furthermore, the positioning component further includes:

[0075] A positioning pad 14 is provided between the nut of the positioning bolt 12 and the first adjusting ring 8;

[0076] A second positioning through hole 15 is provided on the positioning pad 14 , and the screw rod of the positioning bolt 12 passes through the second positioning through hole 15 ;

[0077] A positioning pin 16 is fixedly disposed on the positioning pad 14;

[0078] A third positioning hole 17 is provided on the first arm 4. When the clamp pin 2 is clamped on the first and second arms 4 and 5, the positioning pin 16 extends into the third positioning hole 17. The positioning pin 16 does not interfere with the first adjustment ring 8, preventing it from extending into the third positioning hole 17. The distance between the positioning pin 16 and the third positioning hole 17 matches the distance between the third positioning hole 17 and the first positioning hole 11.

[0079] Furthermore, the first adjustment ring 8 is provided with a plurality of notches 18, through which the positioning pins 16 extend and into the third positioning holes 17. The notches 18 can be provided on the side of the first adjustment ring 8 or on the inside of the side opposite to the first adjustment ring 8. The notches 18 can be arcuate or semicircular in shape. For example, when provided on the side, they can also be rectangular, circular, or the like.

[0080] Furthermore, in order to prevent the pipe clamp pin 2 and the U-shaped pipe clamp 1 from rotating relative to each other, the first adjusting ring 8 can be limited, thereby limiting the position of the entire pipe clamp pin 2.

[0081] Furthermore, the notches 18 are evenly distributed on the sides of the first adjustment ring 8 .

[0082] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
