Step a forming and welding: forming rollers extrude titanium strip into shape, high-frequency induction current rapidly heats the edge of the strip, and extrusion rollers extrude and weld the edge. Step b scraping and finishing: inner and outer scraping knives continuously scrape the weld slag squeezed out at the weld seam, and finishing rollers extrude and correct the roundness and straightness of the welded tube, thereby obtaining a high-frequency induction welded titanium tube. Step c sawing or cold drawing: a high-speed sawing machine cuts the high-frequency induction welded titanium tube to length.

[0004] However, existing tube drawing machines sometimes have gaps at the joints after the sheet metal is made into tubes, which affects the quality of the thermos cup. Utility Model Content

[0007] A further preferred embodiment of this utility model is as follows: the detection ring is provided with a groove, the detector is fixedly connected in the groove, and the detector and the inner sidewall of the detection ring are on the same horizontal plane.

[0008] A further preferred technical solution of this utility model is as follows: the clamp includes an adjusting component and a bolt disposed on the adjusting component. The adjusting component has a specific elastic deformation capability. The adjusting component is provided with an opening. The bolt passes through the adjusting component. When the pipe has a gap, the bolt rotates and the size of the opening changes.

[0009] A further preferred technical solution of this utility model is as follows: a motor is fixedly connected to the machine body, and the output end of the motor is fixedly connected to a bolt. When it is necessary to adjust the tightness of the clamp, the motor starts and the bolt rotates.

[0010] A further preferred embodiment of this utility model is: an elastic block is fixedly connected inside the opening, and the elastic block deforms when the clamp is tightened.

[0015] Compared with the prior art, this utility model includes a body with several detection plates fixedly connected to one side. The detection plates are arranged in a circle to form a detection ring, with a gap between adjacent detection plates. A clamp is fitted over the detection ring. A detector is installed on the inner wall of one of the detection plates and is connected to the clamp. When the pipe enters the detection ring, the detector abuts against the surface of the pipe. When there is a gap at the joint of the pipe, the detector senses and activates the clamp, which tightens and reduces the gap between the two detection plates. Therefore, after the pipe is manufactured, it enters the detection ring. At this time, the gap between the detection plates is automatically adjusted radially according to the diameter of the pipe. When there is a gap in the pipe, the detector senses and sends a command to the clamp. The clamp tightens the detection ring according to the command, thereby reducing the gap between the detection plates and thus closing the gap in the pipe. This design not only allows for alignment and quality inspection after the pipe is manufactured, but also allows for timely correction and closure when gaps are detected, improving the yield rate.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0024] Figures 1-4 As shown, the pipe rounding device includes a body 1. Several detection plates 2 are fixedly connected to one side of the body 1. The detection plates 2 are arranged in a circle to form a detection ring. There is a gap 7 between two adjacent detection plates 2. After the pipe is manufactured, it enters the detection ring. At this time, the detection plates 2 fit with the pipe as it enters. As the pipe goes deeper, the gap 7 between two adjacent detection plates 2 is automatically adjusted according to the pipe diameter, so that the detection plates 2 fit the pipe better. This design facilitates the detection of the pipe.

[0025] Figures 1-4 As shown, an elastic pad 10 is fixedly connected to the inner wall of the detection ring. When the pipe enters the detection ring, the elastic pad 10 deforms due to the compression of the pipe, thereby protecting the surface of the pipe.

[0026] Figures 1-4 As shown, a guide ring 3 is fixedly connected to the side of the detection ring away from the detector 9. The diameter of the guide ring 3 gradually increases from the side closer to the detection ring to the side farther away from the detection ring. The guide ring 3 facilitates the entry of the pipe into the detection ring.

[0027] Figures 1-4 As shown, the detection ring and guide ring 3 are integrally formed, which can reduce the manufacturing difficulty and cost during production.

[0028] Figures 1-4 As shown, the outer sleeve of the detection ring is provided with a clamp 5. The clamp 5 includes an adjusting member 501 and a bolt 502 set on the adjusting member 501. The adjusting member 501 has a specific elastic deformation capacity. The adjusting member 501 is provided with an opening 503. The bolt 502 passes through the adjusting member 501. When the pipe has a gap, the bolt 502 rotates and the size of the opening 503 changes.

[0029] Figures 1-4 As shown, when there is a gap in the pipe, rotating the bolt 502 causes the opening 503 to gradually decrease. At this time, the adjusting part 501 tightens and drives the gap 7 between the detection pieces 2 to decrease, thereby achieving the effect of squeezing the pipe to close the gap. This design allows the detection ring to not only detect the pipe, but also to correct the pipe when it is non-compliant, thereby improving the yield and reducing the probability of defective products.

[0030] Figures 1-4 As shown, a motor 4 is fixedly connected to the body 1. The output end of the motor 4 is fixedly connected to the bolt 502. When it is necessary to adjust the tightness of the clamp 5, the motor 4 starts and the bolt 502 rotates. Therefore, the motor 4 can be started when the bolt 502 needs to be rotated, which reduces the difficulty of operation.

[0031] Figures 1-4 As shown, an elastic block 11 is fixedly connected inside the opening 503. When the clamp 5 is tightened, the elastic block 11 deforms. After the correction is completed, the bolt 502 is rotated in the opposite direction. At this time, the deformed elastic block 11 can open the opening 503, thereby loosening the adjusting part 501 and facilitating the continued advancement of the pipe.

[0032] Figures 1-4 As shown, a detector 9 is provided on the inner wall of one of the detection plates 2. The detector 9 is connected to the clamp 5. The detection ring is provided with a groove 8. The detector 9 is fixedly connected in the groove 8. The detector 9 and the inner wall of the detection ring are on the same horizontal plane. When the pipe enters the detection ring, the detector 9 abuts against the surface of the pipe. When there is a gap at the connection of the pipe, the detector 9 senses and activates the clamp 5. The clamp 5 tightens and the gap 7 between the two detection plates 2 decreases.

[0033] Figures 1-4As shown, when the pipe needs to be inspected, the pipe enters the inspection ring through the guide ring 3. At this time, the inspection piece 2 is in contact with the surface of the pipe, and the detector 9 is also in contact with the pipe. When a gap appears in the pipe, the detector 9 detects it and sends a command to the motor 4. At this time, the motor 4 starts, rotates the bolt 502, reduces the opening 503, and causes the elastic block 11 to deform. The adjusting piece 501 drives the inspection ring to gradually tighten and collect liquid in the pipe, thereby closing the gap. This design plays a role in controlling the motor 4 to complete the fully automatic correction, reducing the difficulty of operation and improving the detection accuracy and correction effect.

[0034] Figures 1-4 As shown, an indicator light 6 is fixedly connected to the detection ring. The indicator light 6 is connected to the detector 9. When the detector 9 detects a gap in the pipe, the indicator light 6 lights up. This design serves to alert the staff and facilitate their observation of the detection effect and working status.

The descriptions of the above embodiments are only for the purpose of helping to understand this utility model and its core ideas.
