[0016] The straightening method of the aluminum profile straightening machine with a material turning function described in the present invention is applicable to the above-mentioned aluminum profile straightening machine with a material turning function, and comprises the following steps: S1. When the incoming material sensing device at the feeding end of the loading and unloading device senses the incoming aluminum profile from the previous process, the control cylinder 1 drives the loading and unloading device to rise to the plane where the conveying material is located to receive the aluminum profile. After receiving the material, the loading and unloading device starts feeding and feeds the aluminum profile between the lower jaw and the upper jaw; S2.

[0020] The technical solution of the present invention is described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figures 1 to 7As shown, the aluminum profile straightening machine with a flipping function of the present invention comprises a frame 1, a U-shaped seat 2 is installed on the frame 1, and a lower jaw 4 and an upper jaw 7 are movable in the U-shaped seat 2, and the lower jaw 4 and the upper jaw 7 are driven to close or open by a driving device; a loading and unloading device 3, the loading and unloading device 3 can be installed on the frame 1 in a lifting manner, and the loading and unloading device 3 is used to load the aluminum profile to be straightened between the lower jaw 4 and the upper jaw 7 or unload the straightened aluminum profile; a flipping device 9, the flipping device 9 is installed on the U-shaped seat 2, and the flipping device 9 is used to flip the straightened aluminum profile and place it on the loading and unloading device 3. The above constitutes the basic structure of the present invention.

[0022] In actual applications, the aluminum profile straightening machine has two sets of frames 1, which are relatively arranged on the guide rails. The bottom of the frames 1 is provided with rollers that move in cooperation with the guide rails. When straightening, the two ends of the aluminum profile are clamped by the two sets of frames 1 respectively, and then the two sets of frames 1 are driven to move in the opening direction on both sides to achieve the straightening of the aluminum profile. Since it is a prior art, it will not be described in detail here; therefore, the present invention is explained with a single frame 1 structure as an embodiment.

[0023] When the present invention is working, the aluminum profile to be straightened is first loaded between the lower jaw 4 and the upper jaw 7 by the loading and unloading device 3 in the ascending position, and the conveying is stopped; the lower jaw 4 and the upper jaw 7 are then driven to close by the driving device to clamp the two ends of the aluminum profile, and then the loading and unloading device 3 is driven to descend and separate from the aluminum profile to avoid the wear caused by the contact between the conveying belt and the aluminum profile during straightening; the two sets of frames 1 move in the direction of opening on both sides, that is, move in the length direction of the aluminum profile to achieve straightening; after straightening, the turning device 9 works The straightened aluminum profile is clamped, and then the driving device drives the lower jaw 4 and the upper jaw 7 to open and reset, so as to loosen the aluminum profile and avoid the turning space, and at the same time prevent the lower jaw 4 and the upper jaw 7 from scratching the surface of the aluminum profile. At this time, the aluminum profile is located on the turning device 9, and the turning device 9 turns the aluminum profile again; after turning, the loading and unloading device 3 is driven to rise, and the turning device 9 loosens the aluminum profile again, and the aluminum profile falls on the loading and unloading device 3, and the loading and unloading device 3 transports the unloaded material to the next process.

[0024] Compared with the prior art, the present invention has obvious advantages, mainly in three aspects: First, the lower jaw 4 and the upper jaw 7 are driven to close or open by a driving device, and the clamping effect is better; in the prior art, the lower jaw 4 is usually used as a fixed structure, and a single driving device is used to drive the upper jaw 7 to move relative to the lower jaw 4 to achieve clamping, but the clamping is not strong enough, and the lower jaw 4 is easy to scratch the surface of the aluminum profile when loading and unloading; Secondly, the loading and unloading device 3 can be lifted and installed on the frame 1. When loading and unloading, it is in an ascending state, and when turning over, it is in a descending state, thereby avoiding the space for the aluminum profile to turn over. At the same time, when straightening and turning over, it does not contact with the surface of the aluminum profile, avoiding wear on the surface of the aluminum profile; in the prior art, manual loading or a fixed structure of the loading and unloading device 3 is usually used, which is easy to cause wear on the surface of the aluminum profile when straightening; Thirdly, a turning device 9 is provided on the U-shaped seat 2, which can automatically turn the straightened aluminum profile, realize the automatic turning function, save labor and increase efficiency, which is conducive to automated production; the prior art does not have a turning device, and manual turning is required, which is cumbersome to operate, requires high labor and low efficiency, and is not conducive to automated production.

[0025] Furthermore, the material turning device 9 includes a fixed seat 11, a second motor 12, an annular rack 13 and a material clamping assembly 14. The fixed seat 11 is installed on the U-shaped seat 2, the second motor 12 is fixed on the fixed seat 11, the annular rack 13 is open, and the opening position allows aluminum profiles to enter and exit. The material clamping assembly 14 is fixed on the inner ring of the annular rack 13, and the material clamping assembly 14 is used to clamp the straightened aluminum profile. The annular rack 13 is driven by the second motor 12 to perform a circular rotation motion and drive the material clamping assembly 14 to clamp the aluminum profile to perform a turning motion. Among them, when the loading and unloading device 3 is feeding, the opening position of the annular rack 13 corresponds to the loading end of the loading and unloading device 3, and the opening position allows aluminum profiles to enter. After turning over, the opening position of the annular rack 13 corresponds to the unloading end of the loading and unloading device 3, and the opening position allows aluminum profiles to be sent out.

[0026] In actual applications, the turning angle can be adjusted according to different profiles, making it more convenient to use.

[0027] Furthermore, a driving gear 16 is fixed to the output end of the motor 2 12, a latching tooth for meshing with the driving gear 16 is formed on the outer edge of the annular rack 13, and a travel limit block 15 is provided at both ends of the annular rack 13, and a limit device is provided between the annular rack 13 and the fixed seat 11. In this way, the latching tooth is arranged on the outer edge of the annular rack 13, so that when the motor 2 12 drives the annular rack 13 to rotate, it will not interfere with the material clamping assembly 14; the travel limit block 15 can prevent the annular rack 13 from being separated from the motor 2 12.

[0028] In actual applications, the angle formed between the travel limit blocks 15 at both ends of the opening of the annular rack 13 and the center of the circle where the annular rack 13 is located is greater than 180°, which is convenient for flipping at different angles according to different profile structures. It can be understood that when the aluminum profile is flipped 180° relative to the initial position, the material flipping is completed.

[0029] Furthermore, the limiting device includes a limiting buckle 17 provided on the fixing seat 11 and a limiting groove 18 provided on the ring rack 13, and the limiting buckle 17 and the limiting groove 18 cooperate to limit. In this way, the ring rack 13 can always make a circular motion in the same plane position during the rotation process, and the motion is more stable without swinging back and forth.

[0030] Further, the clamping assembly 14 includes a cylinder 5 30 and a clamp 31, the cylinder 5 30 is fixed on the annular rack 13, and the clamp 31 is driven to close or open by the cylinder 5 30. In this arrangement, the clamp 31 is driven to close or open by the cylinder 5 30 to clamp or release the aluminum profile.

[0031] Specifically, the central axis of the cylinder 5 30 is on the diameter of the circle where the ring rack 13 is located, and the clamp 31 is located at the center of the circle where the ring rack 13 is located. This arrangement ensures that when the clamping assembly 14 clamps the aluminum profile and moves in a circle with the ring rack 13, the aluminum profile can always maintain the center of the circle where the ring rack 13 is located and rotate. This method is more stable and can also prevent the aluminum profile from moving too much and colliding with the surrounding machines.

[0032] In actual applications, the loading and unloading device 3 feeds the aluminum profile at the longitudinal center axis position of the lower jaw 4 and the upper jaw 7 (specifically, a material sensor is set at the longitudinal center axis position of the lower jaw 4 and the upper jaw 7, and when the aluminum profile is sensed to be in place, the loading and unloading device 3 is controlled to stop conveying to achieve precise feeding). This ensures that after the lower jaw 4 and the upper jaw 7 clamp the aluminum profile and straighten it, the position of the aluminum profile is exactly at the center of the circle where the annular rack 13 is located, thereby ensuring that the clamp 31 can accurately clamp the aluminum profile to perform the turning movement, and at the same time ensure that the aluminum profile will not collide with the surrounding machines (such as the lower jaw 4, the upper jaw 7 and the U-shaped seat 2) when turning the material.

[0033] Furthermore, the U-shaped seat 2 is fixed with a cylinder 3 10, the telescopic rod of the cylinder 3 10 is connected with a rocker arm 19, the rocker arm 19 is fixedly connected with a connecting rod 20, the connecting rod 20 is rotatably mounted on the U-shaped seat 2, the connecting rod 20 is fixedly connected with the fixed seat 11, a positioning device is provided between the connecting rod 20 and the fixed seat 11, and the cylinder 3 10 is used to drive the turning device 9 to move closer to or away from the loading and unloading device 3. Figure 1As shown, when the cylinder three 10 drives the telescopic rod to retract, the telescopic rod pulls the rocker arm 19 to drive the connecting rod 20 to rotate forward, so that the connecting rod 20 drives the fixed seat 11 to rotate forward, thereby driving the flipping device 9 to flip in the direction away from the loading and unloading device 3; when the cylinder three 10 drives the telescopic rod to extend, the telescopic rod pushes the rocker arm 19 to drive the connecting rod 20 to rotate in the opposite direction, so that the connecting rod 20 drives the fixed seat 11 to rotate in the opposite direction, thereby driving the flipping device 9 to flip in the direction close to the loading and unloading device 3, thereby realizing the switching of whether the flipping function is needed at any time according to production needs, which is more convenient to use.

[0034] In actual application, when the driving turning device 9 is close to the loading and unloading device 3, it is used for the turning function. When the driving turning device 9 is far away from the loading and unloading device 3, it is not used for the turning function and avoids the unloading space, so that the material can be unloaded directly.

[0035] Furthermore, the locking device includes a locking strip 21 provided on the connecting rod 1 20 and a locking groove 22 provided on the fixing seat 11, and the locking strip 21 and the locking groove 22 cooperate to lock. In this way, after the fixing seat 11 and the connecting rod 1 20 are assembled, the fixing seat 11 can be prevented from rotating relative to the connecting rod 1 20.

[0036] In practical applications, the fixing seat 11 is fixed to the connecting rod 20 by bolts. After assembly, the fixing seat 11 can be prevented from sliding relative to the connecting rod 20.

[0037] Further, the driving device includes a cylinder 28 and a cylinder 426. The telescopic rod of the cylinder 28 is connected to a connecting rod 23. The connecting rod 23 is fixedly connected to a rocker arm 24. The rocker arm 24 is fixedly connected to a connecting rod 3 25. The connecting rod 3 25 is rotatably mounted on the U-shaped seat 2, and the connecting rod 3 25 is fixedly connected to the upper jaw 7. The cylinder 28 is used to drive the upper jaw 7 to move closer to or away from the lower jaw 4. The telescopic rod of the cylinder 4 26 is fixedly connected to the lower jaw 4. An inclined guide plate 27 is installed in the U-shaped seat 2. Limiting plates 28 are fixed on both sides of the inclined guide plate 27. The lower jaw 4 is movably located on the inclined guide plate 27 between the limiting plates 28 on both sides. The cylinder 4 26 is used to drive the lower jaw 4 to move closer to or away from the upper jaw 7. Anti-slip teeth are provided on both the lower jaw 4 and the upper jaw 7. In this way, Figure 1 As shown, when the upper jaw 7 moves, the telescopic rod is driven to retract by the cylinder 2 8, and the telescopic rod pulls the connecting rod 23 to retract, and the connecting rod 23 drives the rocker arm 24 to rotate with the connecting rod 3 25 as the axis, and the connecting rod 3 25 drives the upper jaw 7 to move relative to the lower jaw 4; Figure 7As shown, the bottom of the lower jaw 4 is slidably connected to the surface of the inclined guide plate 27. When the lower jaw 4 moves, the cylinder 4 26 drives the lower jaw 4 to move upward along the inclined guide plate 27 (in fact, the upward inclination angle of the lower jaw 4 along the inclined guide plate 27 is about 25°), and cooperates with the upper jaw 7 to achieve better clamping of the aluminum profile. After straightening, the upper jaw 7 and the lower jaw 4 are driven to release the aluminum profile.

[0038] In practical applications, since the movements of the lower jaw 4 and the upper jaw 7 do not interfere with each other, the position of the lower jaw 4 on the U-shaped seat 2 can be adjusted according to different profiles for receiving materials, and then the upper jaw 7 can be driven to move relative to the lower jaw 4; the top of the lower jaw 4 is always kept in a flat setting by cooperating with the inclined guide plate 27 and the bottom inclined surface of the lower jaw 4, and a travel limit plate is provided at the end of the inclined guide plate 27 away from the cylinder 28.

[0039] Furthermore, a cylinder 6 and a slide rail 29 are fixed to the frame 1, and the loading and unloading device 3 is slidably arranged on the slide rail 29, and the cylinder 6 is used to drive the loading and unloading device 3 to rise or fall relative to the U-shaped seat 2. In this way, the loading and unloading device 3 is driven by the cylinder 6 to slide and move on the slide rail 29, so as to realize the loading and unloading device 3 rising or falling relative to the U-shaped seat 2.

[0040] In actual application, there are at least two groups of slide rails 29, which are vertically installed on the frame 1, so that the loading and unloading device 3 can be lifted vertically; the loading and unloading device 3 includes a motor 5, a driving wheel, a driven wheel and a conveyor belt, the conveyor belt is wound around the driving wheel and the driven wheel, and the motor 5 is used to drive the driving wheel to rotate so that the conveyor belt can load and unload the aluminum profile. This is a prior art and will not be described in detail. It should be noted that a shell is provided on the outside of the driving wheel and the driven wheel to prevent the conveyor belt from escaping from the driving wheel and the driven wheel, and one end of the shell is bent upward to facilitate loading and unloading, and the telescopic rod of the cylinder 6 is fixedly connected to the shell; wherein, the motor 5 and the cylinder 6 do not interfere with each other when working.

[0041] The straightening method of the aluminum profile straightening machine with a material turning function described in the present invention is applicable to the above-mentioned aluminum profile straightening machine with a material turning function, and comprises the following steps: S1, when the incoming material sensing device at the feeding end of the loading and unloading device 3 senses the incoming aluminum profile from the previous process, the control cylinder 16 drives the loading and unloading device 3 to rise to the plane where the conveying material is located to receive the aluminum profile. After receiving the material, the loading and unloading device 3 starts feeding and feeds the aluminum profile between the lower jaw 4 and the upper jaw 7; S2. When the arrival sensing device on the U-shaped seat 2 senses that the aluminum profile has been delivered, the loading and unloading device 3 is controlled to stop conveying. At this time, the aluminum profile is located at the longitudinal center axis position of the lower jaw 4 and the upper jaw 7; at the same time, since the opening of the annular rack 13 corresponds to the feeding end of the loading and unloading device 3 at the initial time, when the aluminum profile is fed between the lower jaw 4 and the upper jaw 7, the aluminum profile also enters the center position of the circle where the annular rack 13 is located through the opening of the annular rack 13; S3, through the driving device to drive the lower jaw 4 and the upper jaw 7 closed, clamping the end of the aluminum profile, control cylinder 6 to drive the loading and unloading device 3 down reset and out of the aluminum profile, the straightening machine works to straighten the aluminum profile; S4, through the annular rack 13 on the clamping assembly 14 will be straightened aluminum clamping, and then driven by the drive device to open the lower jaw 4 and the upper jaw 7 reset, then the aluminum profile is located on the clamp assembly 14 of the fixture 31; S5, the motor 12 drives the annular rack 13 to rotate in a circle, so that the clamping assembly 14 drives the aluminum profile to rotate 180° relative to the center of the circle where the annular rack 13 is located. At this time, the opening of the annular rack 13 corresponds to the unloading end of the loading and unloading device 3, and the motor 12 stops working; S6, control cylinder 6 drives loading and unloading device 3 to rise to the plane where the conveying material is located, the clamping assembly 14 releases the aluminum profile, and the aluminum profile falls on the loading and unloading device 3. After receiving the material, the loading and unloading device 3 feeds the material and feeds the aluminum profile to the next process; S7. After the feeding is completed, the control cylinder 1 6 drives the loading and unloading device 3 to descend and reset, and at the same time, the motor 2 12 drives the annular rack 13 to rotate and reset in a circle, so that the opening of the annular rack 13 corresponds to the loading end of the loading and unloading device 3, which is convenient for the next aluminum profile to be straightened and turned over.

[0042] It can be understood that when the aluminum profile does not need to be flipped, the flipping device 9 can be pre-driven by the cylinder 3 10 to be away from the loading and unloading device 3 to avoid the loading and unloading space of the aluminum profile, so that the annular rack 13 will not interfere with the aluminum profile. That is, the loading and unloading device 3 feeds the material to the longitudinal center axis position of the lower jaw 4 and the upper jaw 7, and the loading and unloading device 3 descends and separates from the aluminum profile. When the aluminum profile is straightened, the loading and unloading device 3 rises again to receive and support the aluminum profile, and then directly feeds the material to the next process.

[0043] Among them, when the straightening machine of the present invention is used for automated production, the loading and unloading end positions of the loading and unloading device 3, the material arrival position of the U-shaped seat 2 or the longitudinal center axis position of the lower jaw 4 and the upper jaw 7, the rotation stroke of the annular rack 13 driven by the motor 2 12 or the angular position of the aluminum profile flipping by the clamping component 14 can be precisely controlled by setting corresponding sensors, which is beneficial to automated production.

[0044] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, which all belong to the protection scope of the present invention.
