[0016] Preferably, the scrapers are evenly distributed in the inner cavity of the annular cylinder and on one side close to the guide wheel, and the scrapers are installed at an angle. There are two force-bearing plates, and the two force-bearing plates are installed symmetrically along the central axis of the annular cylinder.

The round tube blank can be continuously cleaned through the scraper and the wiping ring, so that the cleaning effect is good, and the interaction between the structures is fully utilized to connect the structures together.
[0019] A method for extruding a TA22 titanium alloy tube for ship use, comprising the following steps:
[0020] Step 1: Feed the titanium alloy round tube to be extruded from the guide wheel, and pass the round tube blank through the center of the wiping circle and the center of the induction coil, turn on the servo motor to work, and under the transmission connection of the transmission, make the lower I-shaped roller rotate with the upper I-shaped roller, and the lower I-shaped roller rotates in the opposite direction to the upper I-shaped roller, so that the round tube blank can be fed with pulling force;
[0021] Step 2: As the round tube billet is continuously moved and loaded, the sticky debris on the outer cylindrical surface of the round tube billet can be scraped off, and the debris can be cleaned in time to promote the discharge and drop of the debris. At the same time, the round tube billet passes through the center of the wiping ring, and the inner ring of the wiping ring can be used to fit the outer cylindrical surface of the round tube billet, so as to wipe the dust and impurities remaining on the outer cylindrical surface of the round tube billet;
[0022] Step 3: Apply a toggle force to the conical cap through the rotating right-angle toggle gear, so that the sleeve rotates and drives the connecting gear to rotate together, and apply rolling pressing force to the force-bearing plate through the circular roller, so that the cleaning component as a whole moves to a position close to the guide wheel.

[0023] Step 4: The cleaned round tube billet will enter the induction coil. The round tube billet passes through the center of the induction coil, generating an induced current in the round tube billet, thereby forming an eddy current, which causes the round tube billet's own temperature to rise rapidly. The sleeve is covered on the outside of the induction coil to keep the heated round tube billet warm.
[0024] Step 5: As the lower I-shaped roller drives the right-angle toggle gear to rotate continuously, the conical cap subjected to the toggle force drives the sleeve to rotate, so that the induction coil is driven by the sleeve to rotate along the axis of the round tube blank, so that the round tube blank can be evenly heated to facilitate the deformation of the round tube blank after being compressed;
[0025] Step 6: The heated round tube blank enters between the lower I-shaped roller and the upper I-shaped roller, and the lower I-shaped roller and the upper I-shaped roller rotate together to extrude the round tube blank, from a round tube to a square tube, changing the shape of the pipe, and using a rotating ring to contact the round tube blank, and the rotating ring can rotate so that the rotating ring and the round tube blank are in rolling contact.

[0049] A processing mechanism 6, which is used to roll and extrude the titanium alloy round tube, and is installed inside the frame 1 and close to the support frame 4;
[0050] The processing mechanism 6 includes a lower I-shaped roller 61 and a transmission 62. The lower I-shaped roller 61 is rotatably mounted inside the frame 1 and close to the support frame 4. The transmission 62 is mounted on the outside of the frame 1 and close to the lower I-shaped roller 61. An upper I-shaped roller 63 is rotatably mounted on the top of the frame 1 and close to the lower I-shaped roller 61. A rotating ring 64 is rotatably mounted on the inner annular surface of the upper I-shaped roller 63 and the inner annular surface of the lower I-shaped roller 61. A servo motor 65 is mounted on the outer side of the transmission 62 and close to the bottom. The lower I-shaped roller 61 and the servo motor 65 are connected by the transmission 62. The lower I-shaped roller 61 and the upper I-shaped roller 63 are installed through the transmission 62. A right-angle toggle gear 66 is fixedly installed at the outer edge of the lower I-shaped roller 61 and at one end away from the servo motor 65. The round tube blank enters between the lower I-shaped roller 61 and the upper I-shaped roller 63. The lower I-shaped roller 61 and the upper I-shaped roller 63 are rotated together to extrude the round tube blank from a round tube to a square tube, thereby changing the shape of the pipe. The rotating ring 64 is used to contact the round tube blank, and the rotating ring 64 can be rotated so that the rotating ring 64 and the round tube blank are in rolling contact, which is not easy to cause scratches on the surface of the tube.
[0051] The upper I-shaped roller 63 is installed directly above the lower I-shaped roller 61 , and the right-angle shifting teeth 66 are evenly distributed on the outer edge of the lower I-shaped roller 61 and away from one end of the servo motor 65 .
[0052] The second embodiment, as Figure 1-Figure 7 As shown, based on the first embodiment:
[0053] A heating mechanism 7 is installed inside the frame 1 and near the lower I-shaped roller 61. The heating mechanism 7 includes a base 71. The bottom of the base 71 is connected to the bottom of the frame 1 by screws. The base 71 is installed near the lower I-shaped roller 61.

A conical cap 74 is fixedly installed at the edge of the outer side of the sleeve 72 and near the lower I-shaped roller 61. The position of the conical cap 74 corresponds to the position of the right-angle toggle tooth 66. The sleeve 72 is away from the conical cap 74. A connecting tooth 75 is fixedly installed at one end of the shaped cap 74, and a circular roller 76 is rollingly installed at the end of the connecting tooth 75 away from the sleeve 72. The cleaned round tube billet will enter the induction coil 73, and the round tube billet passes through the center of the induction coil 73, generating an induced current in the round tube billet, thereby forming an eddy current, which can quickly heat the round tube billet and quickly increase the temperature of the round tube billet itself, thereby preheating the round tube billet, and the sleeve 72 is used to cover the outside of the induction coil 73 to keep the heated round tube billet warm.
[0054] The sleeve 72 is installed horizontally, and the sleeve 72 is installed directly above the base 71. The induction coil 73 is spiral.
[0055] As the lower I-shaped roller 61 drives the right-angled shifting teeth 66 to rotate continuously, the conical cap 74 subjected to the shifting force will drive the sleeve 72 to rotate, so that the induction coil 73 is driven by the sleeve 72 to rotate along the axis of the round tube blank, so that the round tube blank can be evenly heated, which facilitates the deformation of the round tube blank after being compressed.
[0056] The conical caps 74 are evenly distributed at the outer edge of the sleeve 72 and close to the lower I-shaped roller 61 . There are four connecting teeth 75 , and the four connecting teeth 75 are evenly distributed at one end of the sleeve 72 away from the conical cap 74 .
[0057] The third embodiment, as Figure 1-Figure 9 As shown, based on the first and second embodiments:
[0058] A reciprocating mechanism 8 is installed inside the frame 1 and near the guide wheel 3. The reciprocating mechanism 8 includes a linear guide rail 81, which is fixed to the outer side of the frame 1 and one end near the right-angle frame 2 by screws.

[0059] There are two linear guide rails 81 , and the two linear guide rails 81 are symmetrically installed along the frame 1 , and the return spring 83 is installed in the middle of the linear guide rail 81 .
[0060] The cleaning assembly 85 includes an annular cylinder 851, the top of the outer circular surface of the annular cylinder 851 is fixedly installed at the arc-shaped concave surface of the bottom of the arc-shaped connecting beam 84, a scraper 852 is fixedly installed in the inner cavity of the annular cylinder 851 and on one side close to the guide wheel 3, a wiping ring 853 is fixedly installed in the middle of the inner cavity of the annular cylinder 851 through a round rod, and a force plate 854 is fixedly installed at the edge of the inner cavity of the annular cylinder 851 and on one end away from the scraper 852. The staff feeds the titanium alloy round tube to be extruded from the guide wheel 3 and pushes the round tube to the inner cavity of the annular cylinder 851. The tube blank passes through the center of the wiping circle 853 and the center of the induction coil 73, so that the end of the titanium alloy round tube is close to the middle of the lower I-shaped roller 61 and the upper I-shaped roller 63. At this time, the staff starts the servo motor 65 to work, and under the transmission connection of the transmission 62, the lower I-shaped roller 61 and the upper I-shaped roller 63 rotate together, and the lower I-shaped roller 61 and the upper I-shaped roller 63 rotate in opposite directions, so that a pulling force can be applied to the round tube blank, which facilitates the round tube blank to move toward the direction of the cylinder 5, thereby realizing automatic loading.
[0061] The scrapers 852 are evenly distributed in the inner cavity of the annular cylinder 851 and close to the side of the guide wheel 3, and the scrapers 852 are installed at an angle. There are two force plates 854, and the two force plates 854 are installed symmetrically along the central axis of the annular cylinder 851. The scrapers 852 are fitted with the outer cylindrical surface of the round tube blank. As the round tube blank is continuously moved and loaded, the sundries sticking to the outer cylindrical surface of the round tube blank can be scraped off, and the sundries can be cleaned in time. The scrapers 852 are installed at an angle, so that the sundries scraped off can be guided to promote the discharge and drop of the sundries.
[0062] At the same time, the round tube blank passes through the center of the wiping ring 853, and the inner ring of the wiping ring 853 can be used to fit the outer cylindrical surface of the round tube blank, so as to wipe the dust and impurities remaining on the outer cylindrical surface of the round tube blank and reduce the residual debris.
[0063] The right-angle toggle gear 66 rotates by rotating the lower I-shaped roller 61, and is meshed with the conical cap 74 in combination with the right-angle toggle gear 66, so that the right-angle toggle gear 66 in the circular rotation applies a toggle force to the conical cap 74, and under the support of the base 71, the sleeve 72 is rotated, and the sleeve 72 drives the connecting gear 75 to rotate together, so that the circular roller 76 can apply a rolling pressing force to the force-bearing plate 854, and through the sliding connection of the slider 82, the cleaning assembly 85 is moved as a whole to a position close to the guide wheel 3, and the return spring 83 is compressed. As the circular roller 76 continues to rotate, the circular roller 76 is disengaged from the force-bearing plate 854, and the rolling force on the force-bearing plate 854 disappears. Under the elastic force provided by the return spring 83, the cleaning assembly 85 is moved in the opposite direction as a whole, and the cleaning assembly 85 can be used to move back and forth in a straight line, so that the round tube blank can be continuously cleaned by the scraper 852 and the wiping ring 853.

[0066] Step 2: As the round tube blank is continuously moved and loaded, the debris stuck on the outer cylindrical surface of the round tube blank can be scraped off, and the debris can be cleaned in time to promote the discharge and drop of the debris. At the same time, the round tube blank passes through the center of the wiping ring 853, and the inner ring of the wiping ring 853 can be used to fit the outer cylindrical surface of the round tube blank, so as to wipe the dust and impurities remaining on the outer cylindrical surface of the round tube blank;
[0067] Step 3: Apply a toggling force to the conical cap 74 through the rotating right-angle toggling tooth 66, so that the sleeve 72 rotates and drives the connecting tooth 75 to rotate together, and apply a rolling pressing force to the force plate 854 through the circular roller 76, so that the cleaning assembly 85 as a whole moves to a position close to the guide wheel 3. As the rolling force of the circular roller 76 on the force plate 854 disappears, and under the elastic force provided by the reset spring 83, the cleaning assembly 85 as a whole moves in the opposite direction, the cleaning assembly 85 can be used to reciprocate in a straight line, and the round tube blank can be continuously cleaned by the scraper 852 and the wiping ring 853;
[0068] Step 4: The cleaned round tube blank will enter the induction coil 73. The round tube blank passes through the center of the induction coil 73, and an induced current is generated in the round tube blank, thereby forming an eddy current, so that the temperature of the round tube blank itself rises rapidly, and the sleeve 72 is used to cover the outside of the induction coil 73 to keep the heated round tube blank warm;
[0069] Step 5: As the lower I-shaped roller 61 drives the right-angled toggle gear 66 to rotate continuously, the conical cap 74 driven by the toggle force drives the sleeve 72 to rotate, so that the induction coil 73 is driven by the sleeve 72 to rotate along the axis of the round tube blank, so that the round tube blank can be evenly heated to facilitate the deformation of the round tube blank after being compressed;
[0070] Step 6: The heated round tube blank enters between the lower I-shaped roller 61 and the upper I-shaped roller 63, and the lower I-shaped roller 61 and the upper I-shaped roller 63 rotate together to extrude the round tube blank from a round tube to a square tube, changing the shape of the pipe, and the rotating ring 64 is used to contact the round tube blank, and the rotating ring 64 can rotate so that the rotating ring 64 and the round tube blank are in rolling contact.
[0071] When in use, the staff first feeds the titanium alloy round tube to be extruded from the guide wheel 3, and passes the round tube blank through the center of the wiping circle 853 and the center of the induction coil 73, and turns on the servo motor 65 to work, and under the transmission connection of the transmission 62, the lower I-shaped roller 61 and the upper I-shaped roller 63 rotate together, and the lower I-shaped roller 61 and the upper I-shaped roller 63 rotate in opposite directions, so that a pulling force can be applied to the round tube blank for feeding;
[0072] As the round tube blank is continuously moved and loaded, the debris stuck on the outer cylindrical surface of the round tube blank can be scraped off, the debris can be cleaned in time, and the debris can be discharged and dropped. At the same time, the round tube blank passes through the center of the wiping ring 853, and the inner ring of the wiping ring 853 can be used to fit with the outer cylindrical surface of the round tube blank, so as to wipe the dust and impurities remaining on the outer cylindrical surface of the round tube blank. The right-angle toggle tooth 66 in rotation applies a toggle force to the conical cap 74, so that the sleeve 72 rotates and drives the connecting tooth 75 to rotate together, and the circular roller 76 applies a rolling pressing force to the force plate 854, so that the cleaning assembly 85 as a whole moves to a position close to the guide wheel 3. As the rolling force of the circular roller 76 on the force plate 854 disappears, and under the elastic force provided by the reset spring 83, the cleaning assembly 85 moves in the opposite direction as a whole, and the cleaning assembly 85 can be used to reciprocate in a straight line, and the round tube blank is continuously cleaned by the scraper 852 and the wiping ring 853;
[0073] The cleaned round tube blank will enter the induction coil 73, and the round tube blank will pass through the center of the induction coil 73, generating an induced current in the round tube blank, thereby forming an eddy current, so that the temperature of the round tube blank itself rises rapidly, and the sleeve 72 is used to cover the outside of the induction coil 73 to keep the heated round tube blank warm. As the lower I-shaped roller 61 drives the right-angle toggle teeth 66 to rotate continuously, the conical cap 74 subjected to the toggle force will drive the sleeve 72 to rotate, so that the induction coil 73 is driven by the sleeve 72 to rotate along the axis of the round tube blank, so that the round tube blank can be evenly heated to facilitate the deformation of the round tube blank after being compressed.
[0074] The heated round tube blank enters between the lower I-shaped roller 61 and the upper I-shaped roller 63, and the lower I-shaped roller 61 and the upper I-shaped roller 63 rotate together to extrude the round tube blank, from a round tube to a square tube, changing the shape of the pipe, and the rotating ring 64 is used to contact the round tube blank, and the rotating ring 64 can rotate so that the rotating ring 64 and the round tube blank are in rolling contact.
