Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stainless steel pipe strip guide-in, in particular to a high-frequency welded stainless steel pipe strip guide-in device and a use method thereof. BACKGROUND

[0002] Generally, stainless steel pipe production needs to use stainless steel strip to curl, and then the butt joint of the curled stainless steel strip is high-frequency welded to form a stainless steel pipe. The edge of the stainless steel strip is prone to have defects such as protrusions, and generally needs to be polished to improve the quality of the stainless steel strip.

[0003] The defects of the existing stainless steel pipe strip guide-in device are: 1. The prior art KR1020030061996A discloses a steel strip moving conveyor structure, which does not have a structure for polishing the protrusions of the edge of the steel strip. When the steel strip is conveyed into the curling and welding process, the end face of the produced stainless steel pipe has defects such as burrs and protrusions, and therefore a high-frequency welded stainless steel pipe strip guide-in device with a structure for polishing the protrusions of the edge of the stainless steel strip is needed to solve this problem.

[0004] 2. The prior art KR1020080001107A discloses a device for conveying tire steel strips, which does not have a structure for pressing different widths of stainless steel strips. When polishing the edge of the stainless steel strip, the stainless steel strip is prone to tilt or bend outward due to extrusion, affecting the polishing effect of the stainless steel strip. Therefore, a high-frequency welded stainless steel pipe strip guide-in device that can press different widths of stainless steel strips to avoid tilting and bending is needed to solve this problem.

[0005] 3. The prior art JPH05177231A discloses a steel strip conveyor, which does not have a structure for cleaning the edge debris of the stainless steel strip. The presence of edge debris of the stainless steel strip is prone to cause poor welding quality at the welding position due to the presence of debris when the stainless steel strip is welded. Therefore, a high-frequency welded stainless steel pipe strip guide-in device that can clean the debris generated by polishing the stainless steel strip is needed to solve this problem.

[0006] 4. The prior art CN211521103U discloses a copper-iron alloy pipe strip guide-in device, which does not have a structure for facilitating the replacement of bearings and track plates. Bearings and track plates are used to limit and support the strip. When the bearings and track plates need to be replaced, the replacement process is troublesome.

[0031] Please see Figure 1 , Figure 6 and Figure 7 One embodiment of the present invention is a high-frequency welded stainless steel pipe strip feeding device; Including corner plate 20, multiple corner plates 20 are symmetrically installed on both sides of the upper frame 27.

[0032] The operating method of the high-frequency welded stainless steel pipe strip feeding device is as follows: S1. Place the stainless steel strip between pressure roller 3 and pressure roller 29, and then the hydraulic telescopic unit 25 drives pressure roller 29 to move down to press the strip. S2. Next, move the moving ring 8 back and forth so that the friction plate 17 moves to the position where the stainless steel strip is closest to the edge of the pressure roller 3.

Meanwhile, the two brushes 22 are located at the upper and lower positions of the strip respectively. S3. The stainless steel strip moves backward, and the limiting wheel 19 limits both sides of the stainless steel strip. When there is a protrusion on the edge of the stainless steel strip, the protrusion applies pressure to the friction plate 17. After the pressure sensing unit 16 detects that the pressure value reaches the set value, the electric telescopic unit 14 drives the friction plate 17 to move back and forth to polish the protrusion. S4. Brush 22 brushes off the debris present at the edge of friction plate 17.

[0033] S1 also includes the following steps: S11. When the pressure roller 29 moves down, the tension sensing unit 26 detects the tension value. When the tension value is lower than the set value, the hydraulic telescopic unit 25 stops moving.

[0034] Working Principle: Before using the high-frequency welded stainless steel pipe strip feeding device, it should be checked whether there are any problems affecting its use. The stainless steel strip is placed between pressure roller 3 and pressure roller 29. Then, the hydraulic telescopic unit 25 drives pressure roller 29 downwards to press the strip. As pressure roller 29 moves downwards, the tension sensing unit 26 detects the tension value. When the tension value is lower than the set value, the hydraulic telescopic unit 25 stops moving. Then, the moving ring 8 moves back and forth to move the friction plate 17 to the position where the stainless steel strip is closest to the edge of pressure roller 3. At the same time, the edge of the stainless steel strip extends beyond the edge of the pressure roller 3, and the friction plate 17 contacts the edge of the stainless steel strip. Meanwhile, the two brushes 22 are positioned above and below the strip, respectively. The stainless steel strip moves backward, and the limiting wheel 19 limits the two sides of the stainless steel strip. When there is a protrusion on the edge of the stainless steel strip, the protrusion applies pressure to the friction plate 17. After the pressure sensing unit 16 detects that the pressure value has reached the set value, the electric telescopic unit 14 drives the friction plate 17 to move back and forth to polish the protrusion. The brushes 22 brush off the debris present at the edge of the friction plate 17.
