[0043] A fixed top plate is provided on the upper part of one side of the machine base 1, a movable top plate is provided on the upper part of the limit box 103, an extrusion mechanism 6 is provided at the inlet end of the machine base 1 close to the guide roller seat 3, the extrusion mechanism 6 includes two groups of toothed disc driving parts 601 which are respectively movably connected with the machine base 1 and the limit box 103, sleeve b603 and limit pin 607 are fixed on the surface of the machine base 1 and the limit box 103, a T-shaped shaft is slidably provided inside the sleeve b603, and an eccentric disc 604 and a tooth column 605 are respectively fixed on the outer side of the T-shaped shaft, and an extrusion disc 606 is fixed on the end of the T-shaped shaft away from the sleeve b603, the fixed top plate on the machine base 1 and the movable top plate on the limit box 103 are respectively installed with baffle plates 608, and through the setting of the extrusion disc 606 and the baffle plate 608, the aluminum material entering the straightening device can be guided to prevent deviation.

[0044] See also Figure 3-Figure 8An inner cavity is provided inside the end of the roller 401 away from the synchronous wheel a402, and an adjusting column 404 is slidably connected in the inner cavity. The adjusting column 404 is a multi-prism structure, and the adjusting column 404 matches the inner cavity size of the roller 401. The cylindrical end of the adjusting column 404 is movably connected to the left box body of the limit box 103 through a bearing;

[0045] The end of the active rod 406 away from the synchronous wheel b403 is sleeved with a driven cylinder 408, and the end of the driven cylinder 408 away from the active rod 406 is fixed with a slide rod 409, and the outer side of the slide rod 409 is sleeved with a sleeve a410, and the end of the sleeve a410 is connected to the base 1;

[0046] The slide rod 409 is rotationally connected to the left box body of the limit box 103 through a bearing, and the driven cylinder 408 is rotationally connected to the right box body of the limit box 103 through a bearing. The outer sides of the active rod 406 and the slide rod 409 are fixed with a bevel gear a411 and a cam 412. The end of the active rod 406 and the inside of the driven cylinder 408 are both "cross" structures, so that the active rod 406 can drive the driven cylinder 408 to rotate synchronously when rotating.

[0047] See also Figure 5-Figure 7 , Figure 9-11 , bevel gear b502 is meshed and connected with bevel gear a411, a through hole is provided in the middle of the outer straightening roller 504, an oil guide groove 5041 is provided on the circumferential side surface of the outer straightening roller 504, both ends of the oil guide groove 5041 are connected with the through hole of the outer straightening roller 504, a steel wire 5042 is welded in the middle of the oil guide groove 5041, and the steel wire 5042 is used for draining the lubricating oil, a steel ball is embedded in the bottom of the telescopic column 503, and a groove is provided on the surface of the cam 412 for rolling contact with the steel ball. When the lubricating oil moves down along the through hole to lubricate the steel ball, the rotation of the cam 412 can reduce the friction force of rolling contact with the steel ball;

[0048] An oil inlet spring 5043 is welded to the top of the outer straightening roller 504 near the through hole. The oil inlet spring 5043 is in a conical structure. A rotating ring 505 is sleeved on the outer side of the upper part of the outer straightening roller 504 .

[0049] See also Figure 1 , Figure 2 , Figure 5-Figure 7 , Fig. 9 and Fig.11A mounting tube 506 is provided at the top of the rotating ring 505, and a return spring 507 is connected between the rotating ring 505 and the mounting tube 506. The bottom of the rotating ring 505 is rollingly connected to the outer straightening roller 504 through a steel ball. The upper part of the outer straightening roller 504 is inserted in the mounting tube 506, and the mounting tube 506 is threadedly connected to the fixed top plate and the movable top plate respectively. The fixed top plate on the upper part of the machine base 1 and the movable top plate on the upper part of the limit box 103 are both connected with an oil pipeline 8, and the oil outlet of the oil pipeline 8 is connected to the top opening of the mounting tube 506.

[0050] In specific implementation, the roller 401 can drive the active rod 406 to rotate forward through the synchronous wheel b403 and the synchronous belt a407. When the active rod 406 rotates forward, it can drive the driven cylinder 408 and the slide bar 409 to rotate together. When the active rod 406 and the slide bar 409 rotate forward, they can drive the bevel gear a411 to mesh with the bevel gear b502, so that the bevel gear b502 can drive the telescopic column 503 and the outer straightening roller 504 to rotate in the opposite direction through the square tube sleeve 501 in the middle, ensuring that a plurality of outer straightening rollers 504 can extrude the outer side surface of the aluminum material;

[0051] When the active rod 406 and the sliding rod 409 rotate forward, the cam 412 can be driven to rotate continuously, so that the cam 412 can squeeze the bottom end of the telescopic column 503, so that the telescopic column 503 drives the outer straightening roller 504 to slide longitudinally along the inside of the square tube sleeve 501. When the outer straightening roller 504 is squeezed and moves upward, it can push the rotating ring 505 to move upward and compress the return spring 507. When the cam 412 rotates continuously, it will be separated from the squeeze of the telescopic column 503. When the return spring 507 is reset and extended, it can squeeze the outer straightening roller 504 and the telescopic column 503 downward. Therefore, the cam 412 cooperates with the return spring 507 to drive the outer straightening roller 504 to move upward and downward, so that the outer straightening roller 504 can realize the up and down rubbing of the outer side surface of the aluminum material when the aluminum material is rotated and conveyed, and the uneven surface of the side wall of the aluminum material can be smoothed and straightened.

[0052] By connecting the oil inlet of the oil delivery pipe 8 with the matching pump body, the pump body delivers the lubricating oil along the oil delivery pipe 8 to the mounting pipe 506. When the outer straightening roller 504 is extended and retracted up and down and rotated, the lubricating oil can be introduced into the through hole inside the outer straightening roller 504 through the rotating oil introduction spring 5043. Part of the lubricating oil enters the abutment between the rotating ring 505 and the outer straightening roller 504, reducing the rotational friction of the outer straightening roller 504. When the outer straightening roller 504 rotates, the lubricating oil will enter the oil guide groove 5041. The lubricating oil is stably adsorbed in the oil guide groove 5041 along the steel wire 5042 to prevent the lubricating oil from being thrown out by the rotating outer straightening roller 504, thereby ensuring that the rotating outer straightening roller 504 can lubricate the outer side of the aluminum material, so that the friction state of the aluminum material can be improved during straightening, thereby improving the straightening effect, and the lubricating oil can form a good protective film on the surface of the object to reduce wear. At the same time, the use of lubricating oil helps to control the temperature to prevent the straightening process and product quality from being affected by excessive temperature.

[0053] See also Figure 1-Figure 4 A driving motor 101 is installed on the side of the machine base 1 close to the support base 2, and the output rod of the driving motor 101 is connected to one of the rollers 401. An electric push rod 102 is symmetrically installed on the side of the machine base 1 away from the support base 2, and the output end of the electric push rod 102 is fixed to the left box body of the limit box 103; by starting the electric push rod 102 to extend or shorten, the electric push rod 102 can push and pull the left box body of the limit box 103, ensuring that the limit box 103 can drive several external straightening mechanisms 5 on one side of the aluminum material to move horizontally, so that the two adjacent external straightening mechanisms 5 in the horizontal direction can adapt to different widths The aluminum material, and the left box body of the limit box 103 can drive the driven cylinder 408 and the slide bar 409 to move horizontally when pushed and pulled. When the limit box 103 moves horizontally, it can ensure that the slide bar 409 rotates in the sleeve a410. At the same time, the rotation of the active rod 406 can continuously drive the driven cylinder 408 to rotate, ensuring that the lateral adjustment of the outer straightening mechanism 5 on one side will not affect the circumferential rotation and longitudinal extension of the outer straightening roller 504; by pushing and pulling the left box body of the limit box 103, it can also drive one group of extrusion mechanisms 6 to adjust the position horizontally, so that the extrusion mechanism 6 can adapt to the width of the aluminum material.

[0054] See also Fig.12 and Fig.13, synchronous wheels c405 are arranged on the end of the roller 401 close to the guide roller seat 3, the cylindrical end of the adjusting column 404 and the central axis of the toothed disc driver 601, and synchronous belts b602 are connected between one toothed disc driver 601 and the two synchronous wheels c405 on the roller 401, and between the other toothed disc driver 601 and the two synchronous wheels c405 on the adjusting column 404. The ratio of the number of teeth of the toothed disc driver 601 to the number of teeth of the toothed column 605 is greater than 1. When the toothed disc driver 601 rotates at a low speed, it can drive the toothed column 605 and the T-shaped shaft to rotate rapidly. The baffle plate 608 penetrates the T-shaped shaft. The thickness of the toothed column 605 is greater than the thickness of the toothed disc of the toothed disc driver 601. When the T-shaped shaft in the middle of the eccentric disc 604 rotates and retracts in the sleeve b603, the toothed disc of the toothed disc driver 601 will continue to mesh with the toothed column 605.

[0055] A cylindrical guide wheel is fixed on the top of the limiting pin 607, and the cylindrical guide wheel is docked between two adjacent eccentric disks 604. The extrusion disks 606 are distributed at equal angles. The extrusion disks 606 are fan-shaped structures, and the width of one side of the extrusion disk 606 is half the width of the other side of the extrusion disk 606.

[0056] In specific implementation, when the roller 401 close to the guide roller seat 3 is rotating forward, the toothed disc driving member 601 can be driven to rotate forward through the cooperation of the synchronous wheel c405 and the synchronous belt b602. The toothed disc driving member 601 can mesh with the tooth column 605 during the forward rotation, so that the tooth column 605 can quickly reverse and drive the squeeze disc 606 and the eccentric disc 604 to rotate synchronously.

[0057] When the eccentric disk 604 rotates in a circle, it will come into extrusion contact with the cylindrical guide wheel on the top of the limit pin 607, so that when the T-shaped shaft in the middle of the eccentric disk 604 rotates in the sleeve b603, it can drive the T-shaped shaft and the extrusion disk 606 to reciprocate horizontally along the sleeve b603. When the T-shaped shaft drives the extrusion disk 606 to reciprocate horizontally, it can drive the extrusion disk 606 to rotate and extrude the inner side of the aluminum material. When the C-shaped aluminum material presents a concave deformation on both sides of the wall before straightening, the reciprocating extrusion The pressure plate 606 can reciprocate and extrude from the inside to the outside of the aluminum material. By reciprocatingly reducing the distance between the extrusion plate 606 and the baffle plate 608, the two sides of the aluminum material can be stretched outward and straightened. Since the width of one side of the extrusion plate 606 is half the width of the other side of the extrusion plate 606, the inner wall of the aluminum material can be initially straightened through the gradual thickness of the inner fan-shaped surface when the extrusion plate 606 rotates, ensuring the initial straightening of the side and smooth feeding of the aluminum material when it enters from the inlet end of the machine base 1.

[0058] See also Figure 2 , Figure 5 , Fig.14 and Fig.15An internal straightening mechanism 7 is arranged on the fixed top plate of the machine base 1, and the internal straightening mechanism 7 includes a slide 701 installed on the lower side wall of the fixed top plate, and a support rod 702 is slidably connected inside the slide 701, and a fixed frame 703 is installed at the bottom of the support rod 702, and a convex block 704 is symmetrically welded on the shoulder of the upper side of the fixed frame 703, and the convex block 704 on the shoulder of the fixed frame 703 can limit the maximum flip angle of the internal straightening roller frame 705;

[0059] The outer side of the support rod 702 is sleeved with an inner straightening roller frame 705, and both ends of the inner straightening roller frame 705 are provided with roller cylinders for supporting the aluminum profile. The slide 701 is located directly above the roller 401, and the roller cylinders at both ends of the inner straightening roller frame 705 are arranged near the outer straightening roller 504. When the side of the aluminum profile passes between the outer straightening roller 504 and the roller cylinders of the inner straightening roller frame 705, it can ensure that the side of the straightening and extruded aluminum profile is protected from deformation. A torsion spring 706 is connected to the middle part of the fixed frame 703, one end of the torsion spring 706 is connected to the fixed frame 703, and the other end of the torsion spring 706 is connected to the connecting pin on the lower side of the inner straightening roller frame 705, and the bottom of the fixed frame 703 is rotatably connected to a lower pressure roller 707.

[0060] During specific implementation, the inner straightening roller frame 705 is pulled by the torsion spring 706 to rotate around the support rod 702, so that the roller cylinders at both ends of the inner straightening roller frame 705 extrude the aluminum material from the inside to the outside, so that the inner straightening roller frame 705 tightened by the torsion spring 706 can elastically roll the inner wall of the aluminum material, and the inner straightening roller frame 705 extrude the inner wall of the aluminum material from the inside to the outside, and the outer straightening roller 504 extrude the outer wall of the aluminum material from the outside to the inside, so that the two sides of the C-shaped aluminum material have a stable pressing and straightening effect, and at the same time, the lower pressure roller 707 at the bottom of the fixed frame 703 cooperates with the support roller 401 to prevent the bottom of the C-shaped aluminum material from deflection, ensuring that the C-shaped aluminum material has a stable straightening and shaping effect;

[0061] When the electric push rod 102 changes the position of the limit box 103 laterally, the support rod 702 will move laterally along the slide 701, so that the inner straightening roller frame 705 can adapt to the inner wall spacing of aluminum materials of different widths.

[0062] To summarize, the C-shaped aluminum material is sent from the guide roller seat 3 to the inlet end of the machine base 1, and then the drive motor 101 is started to drive several rollers 401 to transport the C-shaped aluminum material. Subsequently, when the aluminum material is sent to the inlet end of the straightening device, it can be stretched and straightened from the inside to the outside through the extrusion mechanism 6. After that, when the aluminum material is transported, the side wall surface of the aluminum material is transported from the outside to the inside through the external straightening mechanisms 5 on both sides, and the transmission mechanism 4 can drive the external straightening rollers 504 of the external straightening mechanism 5 to longitudinally flatten and straighten the outer side surface of the aluminum material. Finally, the external straightening mechanism 5 is used in conjunction with the internal straightening mechanism 7 to ensure that the C-shaped aluminum material can be stably straightened. The straightened aluminum material will be transported and exported from the outlet end of the machine base 1.
