[0004] At present, when making pipes, a meter is used to measure the size of the smooth pipe. Due to the influence of the outer diameter of the pipe and the error of the running mechanism, it cannot meet the customer's tolerance requirement of 0-(+2) mm, and the cutting accuracy is poor. Utility Model Content

The angle steel is positioned by the roller. When the pipe hits the roller, the cutting action signal is triggered to complete the cutting. The device can make the length error of each pipe very small. Each meter needs to add at least 100mm of process material head.

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-4 and Figure 6 A long tube sizing device is shown, comprising a plurality of groups of legs 1, wherein the top of the legs 1 are rotatably connected to angle steels 5, a protection box 12 is fixedly connected to the side wall of the middle leg 1, a motor 3 is installed on the side end of the protection box 12, a first pinion 14 is connected to the output end of the motor 3, a first rotating shaft 2 penetrating the legs 1 is rotatably connected above the first pinion 14, a first large gear 13 is sleeved on the first rotating shaft 2, and the first large gear 13 is meshingly connected with the first pinion 14, a photoelectric sensor 6 is installed on the top of the leg 1 on the left, and the photoelectric sensor 6 is located above the angle steel 5, a support frame is fixedly connected to the leg 1 on the right, a cutting saw 8 is rotatably connected to the bottom end of the support frame, grooves are equidistantly excavated on the angle steel 5, and rollers 4 are rotatably connected in the grooves.

[0027] Figure 5 As shown, a connecting block is fixedly connected to the bottom end of the angle steel 5 , a second large gear 19 is fixedly connected to the bottom end of the connecting block, a second small gear 20 is meshedly connected to the bottom end of the second large gear 19 , and the second small gear 20 is sleeved on the surface of the first rotating shaft 2 .

[0028] This solution can be realized. When cutting stainless steel pipes, a long tube sizing device can be used. The device is composed of a material rack composed of multiple groups of angle steels 5, each group is six meters long, and multiple groups of material racks can be combined according to the length of the pipe, and the material rack can be moved and the height can be adjusted. The first small gear 14 is driven by the motor 3 to drive the first large gear 13 to rotate, so that the second small gear 20 drives the angle steel 5 on the second large gear 19 to flip left and right. The angle steel 5 is positioned by the roller 4. When the pipe hits the roller 4, the action signal of the saw 8 is triggered to complete the cutting. The device can make the length error of each pipe very small. Each meter needs to add at least 100mm of process material head. After using the long tube sizing device, this process material head can be added or added in small amount. Since 8,000-10,000 tons of stainless steel pipes are produced each year, the saving effect is very obvious.

[0029] The second implementation method:

[0030] Figure 1-2 and Figure 7 A support plate 15 is fixedly connected to the side end of the outrigger 1, an electric slide rail is fixedly connected to the side end of the support plate 15, a slide rod 7 is slidably connected to the electric slide rail, a support plate 9 is fixedly connected to the side end of the slide rod 7, a groove is cut at the side end of the support plate 9, a connecting plate 10 is rotatably connected to the groove through a second rotating shaft 16, a cleaning brush 11 is fixedly connected to the bottom end of the connecting plate 10, and the cleaning brush 11 is in conflict with the angle steel 5, a block 17 is symmetrically fixedly connected to one end of the connecting plate 10 near the support frame, a hinge 18 is rotatably connected to the inner wall of the block 17, and the top end of the hinge 18 is rotatably connected to the bottom end of the support plate 9.

[0031] This solution can be achieved. When a long tube sizing device is used to process and cut a stainless steel tube, debris and dust will fall and accumulate on the angle steel 5. At this time, cutting can be stopped regularly during processing, the saw 8 can be turned off and raised, and then the cleaning brush 11 can be rotated perpendicular to the angle steel 5 through the connecting plate 10 so that it contacts the angle steel 5. Then, it is flipped and the hinge 18 is driven to open, thereby increasing the resistance force of the connecting plate 10 to prevent the cleaning brush 11 from shaking left and right during movement. The electric slide rail is turned on to drive the slide rod 7 to drive the cleaning brush 11 to move and clean the dust on the angle steel 5. After cleaning, the cleaning brush 11 can be moved aside and then flipped through the connecting plate 10 again to be level with the support plate 9 to avoid affecting the movement of the stainless steel tube, thereby effectively achieving the effect of regularly cleaning the angle steel 5.

[0032] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
