Description

Technical Field

[0001] The utility model relates to the field of spiral welded pipe production, in particular to a pinch roll device for preventing steel strip deviation and bending. Background Technique

[0002] In a spiral submerged arc welded pipe production line, the steel pipe is formed by bending into a spiral shape, and its weld seam is also in a spiral line shape. Whether the weld seam is misaligned and has undercut will directly affect the inner weld and outer weld effects after forming.

[0003] In the current spiral submerged arc welded pipe production line, a pinch roll device with the X-axis direction as the axis is used to deliver the steel strip to prevent the steel strip from deviating during the delivery process after uncoiling. The traditional pinch roll device can only meet the delivery of steel strips with relatively thick thickness and small elasticity to achieve the effect of preventing deviation, and the pinch roll device also lacks the guiding function in the Y-axis direction. For some steel strips with relatively small thickness and large elasticity, they will deviate in the X-axis direction and bend in the Z-axis direction (that is, the end or both sides of the steel strip are warped and curled) before entering the delivery machine, which will cause misalignment and undercut at the weld seam of the spiral welded pipe after forming, seriously affecting the welding effect.

[0004] Based on this, the present application provides a pinch roll device that can press both sides of the steel strip to prevent the steel strip from deviating along the X-axis and bending in the Z-axis direction to solve the above problems. Summary of the Utility Model

[0035] The rotating roll 2 is horizontally rotatably arranged at the feeding end of the frame 1. This rotating roll can directly utilize the lower roll of the original pinch roll device and can be combined with the original equipment to form a complete and compact assembly relationship, so as to improve the space utilization rate of the equipment.

[0036] The lower support plate assembly 3 is longitudinally arranged on the frame 1 behind the rotating roll 2 for supporting both sides of the steel strip, and the upper surface of the lower support plate assembly 3 is flush with the top of the rotating roll 2, which can ensure that the steel strip enters the pinch roll device horizontally and realizes horizontal delivery, effectively preventing the steel strip from bending and deforming.

[0037] The upper pressing plate assembly 4 is longitudinally arranged on the frame 1 for pressing both sides of the steel strip and is arranged opposite to the lower support plate assembly 3; preferably, one end of the upper pressing plate assembly 4 is aligned with the lower support plate assembly 3, and the other end extends beyond the rotating roll 2. This design enables the upper pressing plate assembly to press the steel plate from the moment the steel strip enters the pinch roll device, effectively preventing the steel plate from shifting and bending.

[0038] Specifically, both the upper pressing plate assembly 4 and the lower support plate assembly 3 include a plurality of rollers C arranged longitudinally for contacting the steel plate, so that the steel strip has a rolling friction with the upper pressing plate assembly and the lower support plate assembly.

[0039] This embodiment realizes long-distance pressing and delivery of the steel strip along the delivery direction, and can effectively prevent the steel strip from shifting in the X-axis direction and bending in the Z-axis direction. Compared with simply using the traditional pinch roll device to deliver the steel strip, it has better guiding and controlling performance and a better delivery effect.

The lower support plate assembly of this embodiment is installed on two cross beams through the lower adjusting blocks. The position of the lower adjusting blocks on the cross beams can be adjusted by loosening them, and thus the distance between the two lower support plates can be adjusted according to the width of the steel strip, as shown in the appendix Figure 3 shown.

[0042] As shown in the appendix Figure 1 shown, the upper pressing plate assembly 4 includes a third cross beam 4.1 and a fourth cross beam 4.2 horizontally arranged on the frame 1, two upper adjusting blocks 4.3 respectively arranged on the third cross beam and the fourth cross beam, and two upper pressing plates 4.4 with both ends fixedly connected to the upper adjusting blocks located on the third cross beam and the fourth cross beam. A plurality of the rollers C are rotatably arranged in the top grooves of the upper pressing plates 4.4. Similarly, the upper pressing plate assembly of this embodiment is installed on two cross beams through the upper adjusting blocks. The position of the upper adjusting blocks on the cross beams can be adjusted by loosening them, and thus the distance between the two upper pressing plates can be adjusted according to the width of the steel strip, as shown in the appendix Figure 3 shown.

[0043] Preferably, the first cross beam 3.1, the second cross beam 3.2, the third cross beam 4.1 and the fourth cross beam 4.2 are all square beams with cylindrical shaft heads at both ends, so that the first cross beam, the second cross beam, the third cross beam and the fourth cross beam can all be rotationally installed structures.

In this embodiment, the first adjusting mechanism and the second adjusting mechanism are used together to adjust the height of the lower support plate, realizing that the height of the lower support plate is adjustable. When abnormal situations such as wear occur to the lower support plate and the lower support plate needs to be replaced, the adjustable structure can reduce the height requirements for the lower support plate, making the interchange cost of parts lower. The gap between the upper support plate and the lower pressing plate is adjusted by the third adjusting mechanism and the fourth adjusting mechanism to adapt to steel strips of different thicknesses.

[0047] As shown in the attached Figure 1 and the attached Figure 2 As shown, the first adjusting mechanism 5 includes a lower shaft seat 5.1, a lower guide key 5.2, a lower pull seat 5.3, an adjusting bolt 5.4 and a lower locking bolt. The lower guide key 5.2 is vertically installed on the frame 1. The lower shaft seat 5.1 is slidably installed on the lower guide key 5.2, and there are a plurality of waist-shaped holes for fixing on the frame on the lower shaft seat 5.1. The lower pull seat 5.3 is fixed on the frame above the lower shaft seat 5.1. The adjusting bolt 5.4 passes through the through hole of the lower pull seat 5.3 and is threadedly connected to the lower shaft seat 5.1. The lower locking bolt is used to lock the lower shaft seat 5.1 on the frame. During specific adjustment, loosen the lower locking bolt and rotate the adjusting bolt to adjust the height of the lower support plate so that the upper surface of the lower support plate is flush with the upper surface of the roller, and then lock the lower locking bolt after adjustment.

[0048] As shown in the attached Figure 1 and the attached Figure 3 and the attached Figure 4 As shown, the second adjusting mechanism 6 includes a chute, a slider 6.1, a limit cover plate 6.2 and an adjusting screw 6.3. There is a chute on the frame 1. The slider 6.2 is slidably arranged in the chute. The limit cover plate 6.2 is sealed above the chute for limiting the slider. The adjusting screw 6.3 threadedly penetrates through the limit cover plate 6.2 and is rotatably connected to the slider 6.1. During specific adjustment, directly rotate the adjusting screw to drive the slider to move up and down by using the adjusting screw, and also make the upper surface of the lower support plate flush with the upper surface of the roller.

[0049] As shown in the attached Figure 1 and the attached Figure 2 As shown, the third adjusting mechanism 7 includes an upper shaft seat 7.1, an upper guide key 7.2, an upper top seat 7.3, a top screw 7.4 and an upper locking bolt.

[0050] As shown in the attached Figure 1 As shown, the fourth adjusting mechanism 8 has the same structure as the second adjusting mechanism 6 and will not be elaborated here.

[0051] Specifically, when adjusting the upper pressing plate, first turn the tightening screw to make it move upward, and then loosen the upper locking bolt. At this time, the upper shaft seat descends under its own weight. Next, according to the thickness of the steel strip, adjust the adjusting screw of the fourth adjusting mechanism to make the lower supporting plate press the steel strip. As the steel strip is delivered into the upper pressing plate, the upper shaft seat moves upward, and then turn the tightening screw to move downward to tighten the upper shaft seat. At this time, the lower pressing plate presses the steel strip, and finally lock the upper locking bolt to fix the upper shaft seat.

[0052] In the above embodiment, as shown in the attached Figure 1 figure, the frame 1 includes a first frame 1.1, a second frame 1.2 and a third frame 1.3.
