[0002] Aluminum profiles are widely used in construction, transportation, and other fields due to their lightweight and high strength. However, after extrusion molding, defects such as bending and twisting are prone to occur, requiring straightening and bending processes. In traditional processes, straightening and bending are mostly completed by separate equipment, which is cumbersome, inefficient, and prone to accuracy errors due to multiple clamping operations.

Slider blocks are installed at both ends of the bottom of the cross frame, and the sliders are slidably connected to the sliding holes.
[0008] Preferably, a lead screw three is rotatably connected at the connection between the bottom of the second base plate and the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Most aluminum profile machines only have one function: either straightening or bending aluminum profiles. This invention integrates both a bending and straightening mechanism on a single base. The straightening mechanism, in conjunction with rollers one, two, three, and four, can straighten bent aluminum profiles and adapt to profiles of varying widths. The bending mechanism follows the straightening mechanism. When bending is required, the straightening mechanism fixes the profile, and a hydraulic telescopic device pushes the bending plate forward. With the cooperation of the bending plate and roller five, the aluminum profile is bent. Furthermore, because the straightening mechanism can move left and right and up and down on the base, and the bending plate size can be changed, the bending mechanism can also be used to bend aluminum profiles of different sizes.
[0013] This utility model simultaneously sets up a straightening mechanism and a bending mechanism on the base, which can work together to save costs and space for equipment placement. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0017] like Figures 1 to 7 As shown, an aluminum profile straightening and bending machine can perform both straightening and bending operations in one machine. It includes a base 1, a bending mechanism 2, and a straightening mechanism 3. The bending mechanism 2 and the straightening mechanism 3 are fixedly connected to the upper end of the base 1. like Figures 1 to 3As shown, the straightening mechanism 3 includes a frame 301, a longitudinal telescopic device 302, and a transverse telescopic device 303. The frame 301 includes a base plate 3018, on which multiple rollers 30110 are fixedly connected. When the machine transports the aluminum profile onto the rollers 30110, the rollers 30110 move forward, reducing friction. Sliding holes 30113 are provided on both sides of the base plate 3018, with the length of the sliding holes 30113 parallel to the length of the rollers 30110. At both ends of the length of the rollers 30110, there are two sliding columns 30114 fixedly connected to the base plate 3018 and two rotatably connected lead screws 3019. The sliding columns 30114 and lead screws 3019 are arranged alternately. 10 has a roller 30111 at one end that is rotatably connected to the base plate 3018. The roller 30111 is perpendicular to the roller 30110. Support columns 3017 are fixedly connected around the base plate 3018. The upper plate 3011 is fixedly connected to the upper end of the support columns 3017. The roller 30111 is rotatably connected to the upper plate 3011. A motor 3012 is fixedly connected to the upper part of the upper plate 3011. The motor 3012 rotates... A gear 3013 is fixedly connected to the moving end. A limiting hole 3014 is fixedly connected to the upper plate 3011 on one side of the motor 3012. A shaft 30116 is rotatably connected inside the limiting hole 3014. A gear 30115 is fixedly connected in the middle of the shaft 30116. The gear 30115 meshes with the gear 3013 for transmission. A bevel gear 3015 is fixedly connected to both ends of the shaft 30116. One of the two lead screws 3019 is left-handed and the other is right-handed. The two lead screws 3019 pass through the upper plate 3011. A bevel gear 3016 is fixedly connected to the upper end of the lead screw 3019. The bevel gear 3015 meshes with the bevel gear 3016 for transmission. The advantage of this design is that when the motor 3012 rotates and the shaft 30116 rotates accordingly, the lead screws 3019 on both sides of the shaft 30116 can simultaneously drive the longitudinal telescopic device 302 to rise or fall.
[0018] like Figure 7As shown, the longitudinal telescopic device 302 includes a longitudinal frame 3021, on which two rollers 3026 are rotatably connected. The rollers 3026 cooperate with the rollers 30110 at the upper end of the rollers 30110 and are responsible for restricting the upper and lower surfaces of the aluminum profile. The longitudinal frame 3021 is fixedly connected to two protrusions 3022 and 3024 on both sides. The protrusions 3022 and 3024 are placed alternately on the longitudinal frame 3021. The protrusion 3022 has a threaded hole 3023, and the protrusion 3024 has a through hole 3025. The threaded hole 3023 is threadedly connected to the lead screw 3019. When the lead screw 3019 rotates, it can drive the longitudinal telescopic device 302 to rise or fall. Because of the staggered threaded holes 3023, it can be ensured that when the longitudinal telescopic device 302 applies pressure to the aluminum profile downward, not only one end is subjected to force, but both ends are subjected to force to compress the aluminum profile.
[0019] like Figure 5 As shown, the lateral telescopic device 303 includes a crossbeam 3031, on which multiple rollers 3032 are rotatably connected. The rollers 3032 and rollers 30110 are staggered, and the rollers 3032 and 30111 work together to apply pressure and straighten the left and right sides of the aluminum profile. A threaded hole 3034 is provided in the middle of one side of the bottom of the crossbeam 3031. Telescopic columns 3033 are fixedly connected to both ends of one side of the bottom of the crossbeam 3031. Slider blocks 3035 are installed at both ends of the bottom of the crossbeam 3031, and the sliders 3035 are slidably connected to the sliding holes 30113. A lead screw 305 is rotatably connected to the bottom of base plate 2 3018 at the junction with base 1. Lead screw 305 is threaded into threaded hole 2 3034. An opening is provided at the bottom of base plate 2 3018 to facilitate the passage of telescopic column 3033. Thus, when the lateral telescopic device 303 applies pressure to the aluminum profile, the telescopic column 3033 acts as a limit, preventing deviation and ensuring proper straightening of the aluminum profile. One end of lead screw 305 is fixedly connected to motor 2 304, which is fixedly connected to base 1. The rotating end of motor 2 304 is fixedly connected to lead screw 305. Motor 2 304 drives lead screw 305 to rotate, thereby enabling the lateral telescopic device 303 to move left and right.
[0020] like Figure 4 As shown, a long groove 101 is provided on one side of the base 1, and multiple fixing slots 102 are provided on the base 1 at the bottom of the long groove 101. The long groove 101 is provided with a bending mechanism 2. Figure 6As shown, the bending mechanism 2 includes a base plate 204, with a threaded post 201 fixedly connected to the bottom center of the base plate 204. The threaded post 201 is located in the long groove 101, and a locking block 203 is slidably connected to the threaded post 201, abutting against the fixed slot 102. A nut 202 is threadedly connected to the threaded post 201, abutting against the bottom of the base plate 204. The reason for this design is that this utility model can perform bending work on aluminum profiles of different sizes. By moving the bending mechanism 2 within the long groove, the distance can be adjusted to adapt to different aluminum profiles. After finding a suitable position, the locking block 203 on the threaded post 201 locks into the fixed slot 102 to fix the bending mechanism 2. A threaded post 206 is fixedly connected to the middle of the upper part of the base plate 204. Hollow posts 205 are fixedly connected to the four sides of the base plate 204. Multiple pin holes 2051 are opened on the side of the hollow posts 205. An upper plate 210 is provided on the upper part of the base plate 204. A threaded post 211 is fixedly connected to the middle of the bottom of the upper plate 210. Pins 209 are fixedly connected to the four sides of the bottom of the upper plate 210. Multiple pin holes 2091 are opened on the side of the pins 209. Pins 207 are slidably connected in the pin holes 2051 and pin holes 2091. Rotating posts 208 are threadedly connected to both the threaded post 211 and the threaded post 206. The reason for this design is that when bending aluminum profiles of different sizes, the center of the bending plate 213 needs to be aligned with the center of the aluminum profile. During alignment, the pin 207 needs to be removed from the pin hole 2051 and the pin hole 2091. The height of the upper plate 210 is adjusted by manually rotating the rotating column 208. After finding the appropriate position, the pin 207 is inserted into the pin hole 2051 and the pin hole 2091 for fixation. During the working process, the change in the height of the upper plate 210 caused by the movement of the rotating column 208 affects the bending work.
[0021] A hydraulic telescopic device 212 is fixedly connected to the upper part of the upper plate 210. A bending plate 213 is rotatably connected to the extended end of the hydraulic telescopic device 212. A spring 214 is fixedly connected to the back of the bending plate 213 away from the straightening mechanism 3. One end of the spring 214 is fixedly connected to the hydraulic telescopic device 212. The upper and lower ends of the front of the bending plate 213 have limiters. When the spring 214 is in operation, if only straightening is needed and bending is not required, the hydraulic telescopic device 212 retracts the bending plate 213. Under the action of the spring 214, the length direction of the bending plate 213 remains parallel to the direction of the aluminum profile's inlet and outlet, and will not touch the aluminum profile, thus preventing damage to the aluminum profile. When the aluminum profile needs to be bent, the hydraulic telescopic device 212 pushes the bending plate 213 forward. Initially, before contacting the aluminum profile, the bending plate 213 rotates outward. As the bending plate 213 gradually comes into contact with the aluminum profile, it gradually becomes parallel. As it continues to extend forward, the bending plate 213 begins to rotate inward, thus achieving the bending operation of the aluminum profile. The upper and lower limiters on the bending plate 213 primarily serve to fix the aluminum profile, preventing it from extending too far and drooping downwards, which would affect the bending effect.
[0022] A roller 306 is rotatably connected to the upper plate 3011 between the bending mechanism 2 and the straightening mechanism 3. The roller 306 is rotatably connected to the bottom plate 3018. The function of the roller 306 is to contact the aluminum profile during bending, changing the sliding friction to rolling friction to reduce damage to the surface of the aluminum profile.
[0023] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.
[0024] Working process: The aluminum profile to be straightened is conveyed to roller 30110 at one end of the straightening mechanism 3. Motor 304 is started, and the rotation of motor 304 drives lead screw 305 to rotate. When lead screw 305 rotates, the lateral telescopic device 303, which is screwed to lead screw 305, moves to the side of roller 30111, clamping the aluminum profile laterally. Then, motor 3012 is started, and motor 3012 drives gear 3013 to rotate. Gear 3013 meshes with gear 30115, and shaft 30116, which is fixedly connected to gear 30115, rotates. The bevel gears 3015 at both ends of shaft 30116 drive the bevel gears 3016 at the upper ends of the two lead screws 3019 to rotate, causing the longitudinal telescopic device 302, which cooperates with lead screw 3019, to move downward. This causes roller 3026 on the longitudinal telescopic device 302 to cooperate with roller 30110 to clamp the aluminum profile. As the aluminum profile moves forward, it is gradually straightened from a bent state by being surrounded by rollers 30110, 30111, 3026, and 306. At this time, the hydraulic telescopic device 212 in the bending mechanism 2 is not working and is in a retracted state. The bending plate 213 is stretched by the spring 214 and is parallel to the aluminum profile, which will not affect the straightening of the aluminum profile. The straightened aluminum profile can be taken out from the other end of the straightening mechanism 3.
[0025] When bending of the aluminum profile is required, the aluminum profile enters from one end of the straightening mechanism 3, and is straightened once to prevent bending in some areas. After the straightened aluminum profile comes out of the straightening mechanism 3, when it extends to the area that needs to be bent, the hydraulic telescopic device 212 drives the bending plate 213 to move forward. When the bending plate 213 contacts the aluminum profile, the front of the bending plate 213 gradually contacts the aluminum profile. When the front of the bending plate 213 is in full contact with the aluminum profile, it continues to push forward. The bending plate 213 pushes the aluminum profile. When the aluminum profile encounters the roller 30112, the bending plate 213 continues to push and bend. The bending plate 213 rotates and presses tightly against the aluminum profile until the bending operation is completed. The hydraulic telescopic device 212 then drives the bending plate 213 to retract.
[0026] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
