Description

Technical Field

[0001] This invention relates to the field of aluminum profile manufacturing technology, and in particular to an adaptive traction device for aluminum profile preparation. Background Technology

[0002] Aluminum profile extrusion is an important plastic processing method. It involves applying pressure to an aluminum billet placed in an extrusion cylinder, causing it to undergo directional plastic deformation and be extruded from the die orifice to obtain a profile product with the desired cross-sectional shape and size. In the aluminum profile extrusion process, traction equipment plays a crucial role. The main function of traction equipment is to pull the extruded aluminum profile. Traction equipment is key equipment to ensure the straightness, dimensional accuracy, and surface quality of the profile. In recent years, with the rapid development of automatic control, sensors, industrial communication, and artificial intelligence technologies, aluminum profile traction equipment has evolved from traditional manual adjustment and mechanical transmission to intelligent systems. A number of intelligent traction equipment with automatic control functions have been widely used in the industry.

[0003] However, existing intelligent traction equipment still has many shortcomings in practical applications: During the traction process of aluminum profiles, due to the complex cross-sectional shape of the profiles and the fact that they are not fully cooled and straightened when they are just demolded, the aluminum profiles undergo local deformation (bending up and down) during traction. The existing limiting methods mostly involve clamping one end of the aluminum profile from the top and bottom and supporting the middle section of the aluminum profile with rotating rollers at multiple points. When the local deformation point of the aluminum profile passes one of the rotating rollers, the local deformation point of the aluminum profile will tend to shift relative to the rotating roller (for example, if the aluminum profile bends upward locally, a gap will be formed between the aluminum profile deformation point and the rotating roller, causing the rotating roller deformation point to be suspended and the whole profile to tend to bend downward; when the aluminum profile bends downward locally, there will be a force squeezing the rotating roller at the aluminum profile deformation point, causing the whole aluminum profile to tend to bend upward). This causes the aluminum profile to shift as a whole, which in turn causes the clamping point of the aluminum profile to be affected by the offset force, aggravating the deformation of the aluminum profile and ultimately affecting the quality of the aluminum profile after forming. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the background art, the present invention provides an adaptive traction device for aluminum profile manufacturing.

[0005] The technical implementation of the present invention is as follows: an adaptive traction device for aluminum profile manufacturing, comprising a base frame, an electric slide block slidably connected to the base frame, a base plate fixedly connected to the electric slide block, an arc-shaped block mounted on the electric slide block via an electric roller, a plurality of spaced-apart slide frames slidably connected to the base frame, an electric push rod mounted on each slide frame, a fixed frame fixedly connected to the telescopic part of the electric push rod, a rotating frame rotatably connected to the fixed frame, a limiting part for limiting the rotation angle of the corresponding rotating frame, two sliding rods slidably connected to both the fixed frame and the rotating frame, a rotating shaft rotatably connected to each sliding rod, two pressure sensors mounted on both the fixed frame and the rotating frame, and a first elastic element fixedly connected between each sliding rod and an adjacent pressure sensor.

[0006] Furthermore, the rotating shaft is fixed with two symmetrically distributed sets of pressure strips, each set of pressure strips having several circumferentially evenly distributed strips, and the thickness of the pressure strips gradually decreases from near the central axis of the adjacent rotating shaft to a distance away.

[0007] Furthermore, the arc-shaped block is fixedly connected to symmetrically distributed elastic blocks, and the elastic blocks are fixedly connected to pressure blocks.

[0008] Furthermore, the pressure block is slidably connected to symmetrically distributed sliding plates, the sliding plates are provided with inclined surfaces, and a second elastic element is fixedly connected between the sliding plates and the adjacent pressure blocks.

[0009] Furthermore, the base frame is fixedly connected to two symmetrically distributed sets of fixed frames, each set of fixed frames having several fixed frames spaced apart, the fixed frames are slidably connected to connecting blocks, the connecting blocks of two adjacent fixed frames in different sets are rotatably connected to rotating rollers, a third elastic element is fixedly connected between the fixed frames and the connecting blocks, and the base plate is provided with an inclined surface in the direction away from the adjacent fixed frames, the inclined surface of the base plate is used to squeeze the rotating rollers to move.

[0010] Furthermore, the sliding frame is fixedly connected to symmetrically distributed limiting rods, each limiting rod is fixedly connected to a first limiting ring, and each limiting rod is threadedly connected to a second limiting ring. The first limiting ring and the second limiting ring are used to limit the corresponding sliding frame.

[0011] Furthermore, two elastic strips are fixedly connected between two adjacent fixed frames and between two adjacent rotating frames.

[0012] Furthermore, the sliding rod is fixed to a limiting plate, and the elastic strip passes through the limiting plate.

[0013] Furthermore, the elastic strip is fixed with a plurality of elastic balls spaced apart, the elastic balls being used to limit the movement of the aluminum profile.

[0014] Furthermore, the elastic coefficient of the elastic strip is greater than that of the elastic ball.

[0015] This invention has the following advantages: It uses several sliding rods to adaptively detect the shape of the aluminum profile. When the aluminum profile undergoes localized bending, the corresponding sliding rod moves, and the electric rollers of the electric carriage control the arc-shaped block to temporarily stop pulling the aluminum profile, thus reducing the probability of increased deformation during traction due to localized deformation and offset between the aluminum profile and its support position. This ensures the quality of the formed aluminum profile. When the aluminum profile passes the sliding rod at the point of localized deformation, two pressure blocks alternately press the aluminum profile, with one pressure block ceasing to press... During the tightening process of the aluminum profile, another pressure block moves the aluminum profile using a flexible clamping method until the local deformation point of the aluminum profile moves away from the sliding rod. The pressure block then tightens the aluminum profile, aligning it and reducing the probability of deformation between the aluminum profile and the sliding rod due to local deformation. This ensures the normal traction of the aluminum profile and the quality after traction. Multiple first elastic strips, multiple second elastic rings, and multiple third elastic strips support and limit the aluminum profile around its perimeter to reduce the probability of local deformation during traction, thereby ensuring the quality of the aluminum profile after traction.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1

[0026] An adaptive traction device for aluminum profile manufacturing, such as Figures 1-3 , Figure 6 and Figure 7As shown, the system includes a base frame 1, on which a control terminal (not shown) is mounted. An electric slide 2, electrically connected to the control terminal, is slidably connected to the base frame 1. A base plate 201 is fixed to the electric slide 2, supporting the aluminum profile. An arc-shaped block 3 is mounted on the electric slide 2 via an electric roller, which is electrically connected to the control terminal. The electric roller drives the arc-shaped block 3 to reciprocate, causing the left and right sides of the arc-shaped block 3 to alternately press against the aluminum profile. Several spaced-apart slide frames 4 are slidably connected to the base frame 1. An extruder and a slitting machine (not shown) are located on the left side of the base frame 1. Electric push rods 5, electrically connected to the control terminal, are mounted on the slide frames 4. In this embodiment, all slide frames... The movable frame 4 is electrically driven (e.g., an electromagnetic slide rail is installed on the base frame 1, and the sliding frame 4 is an electric slider that slides within the electromagnetic slide rail), driving the electric push rod 5 to move left and right. By having all the sliding frames 4 move sequentially to the right, the aluminum profile is supported in segments, allowing all the sliding frames 4 to move sequentially with the aluminum profile. This disperses the traction force on the aluminum profile, reducing the traction force on the right end of the aluminum profile, thereby reducing the probability of deformation. A fixed frame 6 is fixedly connected to the telescopic part of the electric push rod 5. The telescopic part of the electric push rod 5 is used to drive the fixed frame 6 to move up and down. A rotating frame 7 is rotatably connected to the fixed frame 6. The fixed frame 6 is provided with a limiting part for limiting the rotation angle of the corresponding rotating frame 7. At the rear of the upper side of the fixed frame 6, both the fixed frame 6 and the rotating frame 7 are slidably connected to two sliding rods 8. During the traction of the aluminum profile, the four sliding rods 8 on the fixed frame 6 and the adjacent rotating frame 7 are respectively located around the aluminum profile. The sliding rods 8 are rotatably connected to a rotating shaft 9. Both the fixed frame 6 and the rotating frame 7 are equipped with two pressure sensors 10, which are electrically connected to a control terminal. A first elastic element 11 is fixed between the sliding rod 8 and the adjacent pressure sensor 10. The first elastic element 11 is a compression spring. During the traction of the aluminum profile, the four sliding rods 8 respectively limit the movement of the aluminum profile around its perimeter. If the aluminum profile bends locally, the corresponding direction will be limited. The sliding rod 8 moves adaptively under the pressure of the aluminum profile, and in the process, it deforms the first elastic element 11. The deformation of the first elastic element 11 changes the pressure on the pressure sensor 10 to monitor the local deformation of the aluminum profile. When the aluminum profile is locally deformed and the degree of deformation exceeds the threshold, the pressure sensor 10 transmits an electrical signal to the control terminal. The electric slide 2 drives the arc block 3 to rotate through the electric roller, so that the arc block 3 temporarily stops pulling the aluminum profile to move, thereby reducing the probability of the aluminum profile shifting from its support position due to local deformation, which would increase the deformation of the aluminum profile during the traction process, and thus ensuring the quality of the aluminum profile after forming.

[0027] like Figure 7As shown, two sets of symmetrically distributed pressure strips 12 are fixed to the rotating shaft 9. Each set of pressure strips 12 has several circumferentially evenly distributed pressure strips 12. The pressure strips 12 are made of heat-resistant rubber. The thickness of the pressure strips 12 gradually decreases from the central axis of the adjacent rotating shaft 9 to the distance away. The pressure strips 12 press the surface of the aluminum profile. During the traction process, the aluminum profile moves relative to the pressure strips 12, causing the pressure strips 12 to drive the rotating shaft 9 to rotate. This reduces the contact area between the aluminum profile and the limiting structure around it, and reduces the friction force on the aluminum profile during its movement. This reduces the probability of deformation of the aluminum profile due to pressure, and ensures the quality of the aluminum profile after traction.

[0028] like Figure 3 and Figure 4 As shown, the arc-shaped block 3 is fixed with two pairs of elastic blocks 13 symmetrically distributed on the left and right. The same pair of elastic blocks 13 are fixed with pressure blocks 14. During the reciprocating rotation of the arc-shaped block 3, the arc-shaped block 3 drives the two pressure blocks 14 to rotate through the four elastic blocks 13. The two pressure blocks 14 alternately press the aluminum profile. Taking the right pressure block 14 no longer pressing the aluminum profile as an example, during the process of the left pressure block 14 pressing the aluminum profile, the two elastic blocks 13 on the left are gradually compressed. When the aluminum profile passes the sliding rod 8 at the local deformation point, the aluminum profile is moved to the right and straightened in a flexible clamping manner to ensure the quality of the aluminum profile after traction.

[0029] like Figure 3 and Figure 4 As shown, the pressure block 14 is slidably connected to two symmetrically distributed sliding plates 15. The sliding plates 15 are provided with inclined surfaces, and the inclined surfaces of the sliding plates 15 are provided in the direction of the aluminum profile. A second elastic element 16 is fixed between the sliding plate 15 and the adjacent pressure block 14. The second elastic element 16 is a tension spring, which limits the aluminum profiles of different models through the inclined surfaces of the two sliding plates 15.

[0030] The specific working principle is as follows:

[0031] Before the operator needs to use this device to intelligently traction the aluminum profile, the operator flips all the rotating frames 7 forward and activates the automated process with one click via the control terminal: The system first autonomously issues a command to drive the telescopic part of the electric push rod 5 to retract, so as to drive the fixed frame 6 and the rotating frame 7 to accurately descend to the standby position, ensuring that the electric slide 2 can be automatically guided to the left starting area of ​​all the slide frames 4 without interference. The electric push rod 5 is then closed via the control terminal, and the aluminum profile is extruded from the extruder on the left side of the device. The electric slide 2 is then opened via the control terminal, and the electric slide 2 moves to the left to the left side of the base frame 1 and the slitting machine. The electric roller and pressure sensor 10 drive the arc block 3 to rotate. The arc block 3 drives the two pressure blocks 14 to rotate through two elastic blocks 13. One of the pressure blocks 14 presses the right end of the aluminum profile. The corresponding elastic block 13 is deformed to its limit under pressure, so that the right end of the aluminum profile is clamped between the base plate 201 and the pressure block 14 located on the lower side. As the aluminum profile is extruded and formed, the electric carriage 2 drives the right side of the aluminum profile to move to the right through the base plate 201, the pressure block 14 located at the lower part and all the sliding plates 15 on it. The control terminal dynamically adjusts the right movement rate of the electric carriage 2 through the servo algorithm based on the real-time discharge speed and tension feedback of the extruder.

[0032] During the process of the base plate 201 and the arc block 3 driving the aluminum profile to move to the right, when the electric slide 2 moves to the right side of all the slide frames 4, the electric push rod 5 is activated through the control terminal. The telescopic part of the electric push rod 5 extends to drive the fixed frame 6 and the rotating frame 7 to move upward. The control terminal is then activated to turn off the electric push rod 5, causing all the rotating frames 7 to flip backward and reset. The four sliding rods 8 on the fixed frame 6 and the adjacent rotating frames 7 respectively limit the four sides of the aluminum profile. The corresponding pressure strips 12 on the four rotating shafts 9 limit the aluminum profile. The operator can then... The control terminal activates the electric slide 2, which moves to the right. The upper base plate 201, the lower pressure block 14, and all the sliding plates 15 on the electric slide 2 drive the aluminum profile to move to the right, thus tractioning the aluminum profile. During this process, all the sliding frames 4 move to the right sequentially from right to left. By moving to the right sequentially, the aluminum profile is supported in sections, allowing all the sliding frames 4 to move with the aluminum profile in sequence. This disperses the traction force on the aluminum profile, reduces the traction force on the right end of the aluminum profile, and thus reduces the probability of deformation of the aluminum profile.

[0033] During the traction process of aluminum profiles, taking a sliding frame 4 as an example, if the aluminum profile is partially bent, the aluminum profile will press the corresponding pressure strip 12, causing the rotating shaft 9 to drive the sliding rod 8 to move, so that the corresponding sliding rod 8 will move adaptively and compress the first elastic element 11 to deform. Through the deformation of the first elastic element 11, the pressure on the pressure sensor 10 is changed to monitor the local deformation of the aluminum profile. When the aluminum profile is partially deformed and the degree of deformation exceeds the threshold, the pressure sensor 10 transmits an electrical signal to the control terminal. The electric sliding frame 2 drives the arc block 3 to rotate through the electric roller, so that the arc block 3 temporarily stops pulling the aluminum profile. During the process of pressing the aluminum profile with another pressure block 14, the aluminum profile is moved in a flexible clamping manner until the part of the aluminum profile with local deformation moves to the point of separation from the sliding rod 8 and the pressure strip 12. The pressure block 14 presses the aluminum profile to restore the stability of the aluminum profile, thereby reducing the probability of deformation between the aluminum profile and the supporting structure due to local deformation, and thus ensuring the normal traction of the aluminum profile and the quality after traction.

[0034] After the aluminum profile is pulled, the slitting machine cuts the aluminum profile. The base plate 201, the pressure block 14 located at the bottom and all the sliding plates 15 on it drive the aluminum profile to move to the right. The operator collects the cut aluminum profile and then controls the electric slide 2 to move to the left and reset through the control terminal. All the sliding frames 4 move to the left and reset. After the electric slide 2 moves to the left of the base frame 1 and the left side of the slitting machine, the above steps are repeated to continuously pull, cut and collect the aluminum profile. When the operator no longer needs to use this device to pull the aluminum profile, the electric slide 2, electric roller and pressure sensor 10 are turned off through the control terminal.

[0035] Example 2

[0036] Based on Example 1, such as Figure 1 and Figure 2As shown, the base frame 1 is fixedly connected to two symmetrically distributed sets of fixed frames 17. Each set of fixed frames 17 has several fixed frames 17 spaced apart. The fixed frames 17 are slidably connected to connecting blocks. The connecting blocks of two adjacent fixed frames 17 in different sets are rotatably connected to rotating rollers 18. A third elastic element 19 is fixedly connected between the fixed frames 17 and the connecting blocks. The third elastic element 19 is a compression spring. The base plate 201 is provided with an inclined surface in the direction away from the adjacent fixed frame 6. During the process of the electric slide 2 driving the base plate 201 to move to the right, the base plate 201 gradually... The roller gradually moves to contact with the leftmost rotating roller 18. The inclined surface of the base plate 201 presses all the rotating rollers 18 in sequence, causing all the rotating rollers 18 to move downward in sequence. The third elastic element 19 is compressed. After the base plate 201 passes the rotating rollers 18, the third elastic element 19 rebounds, causing the rotating rollers 18 to move upward and contact the pulled aluminum profile, thereby supporting the bottom of the aluminum profile during the unloading process. When the rotating rollers 18 move upward to the limit position, the upper side of the rotating rollers 18 and the upper side of the base plate 201 are on the same horizontal plane.

[0037] like Figure 5 As shown, in the above embodiment, all sliding frames 4 are electrically driven (e.g., an electromagnetic slide rail is provided on the base frame 1, and the sliding frame 4 is an electric slider that slides within the electromagnetic slide rail), to drive the electric push rod 5 to move left and right. In this embodiment, only the rightmost sliding frame 4 is electrically driven. The sliding frame 4 is fixedly connected to two symmetrically distributed limiting rods 20. The limiting rods 20 pass through the corresponding sliding frame 4. The limiting rods 20 are fixedly connected to a first limiting ring 21, and the limiting rods 20 are threadedly connected to a second limiting ring 22. By rotating the second limiting ring 22, the position of the second limiting ring 22 is adjusted. During the process of the rightmost sliding frame 4 moving to the right, the sliding frame 4 drives the first limiting ring 21 and the second limiting ring 22 to move to the right through the limiting rods 20. After the second limiting ring 22 moves to engage with the second sliding frame 4 on the right, the second limiting ring 22 drives the second sliding frame 4 on the right to move. Then, the second sliding frame 4 on the right drives the two limiting rods 20 on it to move. This process is repeated so that all sliding frames 4 move to the right in sequence. When the aluminum profile is pulled and the electric sliding frame 2 moves to the left to reset, the right sliding frame 4 moves to the left to reset. The right sliding frame 4 drives the first limiting ring 21 to move to the left through the limiting rod 20. The first limiting ring 21 moves to contact the second sliding frame 4 on the right. The first limiting ring 21 drives the second sliding frame 4 on the right to move, so that all sliding frames 4 move to the left in sequence. The first limiting ring 21 and the second limiting ring 22 are used to limit the corresponding sliding frames 4.

[0038] Example 3

[0039] Based on Example 2, such as Figure 5 and Figure 6As shown, two elastic strips 23 are fixed between each pair of adjacent fixed frames 6 and between each pair of adjacent rotating frames 7. Four adjacent elastic strips 23 are located around the aluminum profile. Initially, the elastic strips 23 are relaxed and bent downwards in the middle. When the distance between the two sliding frames 4 reaches its limit, the elastic strips 23 deform and become taut. A limiting plate 24 is fixed to the sliding rod 8, and the elastic strips 23 pass through the limiting plate 24. Several spaced elastic balls 25 are fixed to the elastic strips 23. Both the elastic strips 23 and the elastic balls 25 are made of heat-resistant rubber. The elastic balls 25 are used to limit the movement of the aluminum profile. The elastic coefficient of the elastic strip 23 is greater than that of the elastic balls 25. When all the elastic balls 25 are in contact with the aluminum profile, the elastic strips 23 remain taut, limiting the movement of the aluminum profile. The deformation of the elastic balls 25 adapts to the aluminum profile. At the deformation points of the profile, the probability of damage to the clamped parts caused by shaking is reduced, thereby ensuring the quality of the aluminum profile after traction. As the sliding frame 4 moves to the right through the electric push rod 5, the fixed frame 6 and the rotating frame 7 are gradually stretched and deformed. As all the sliding frames 4 move, all the elastic strips 23 are stretched and approach different sections of the aluminum profile. During the movement of the sliding frame 4, the limiting plate 24 limits the elastic strips 23, so that all the elastic balls 25 on the elastic strips 23 are in close contact with different types of aluminum profiles (by moving the sliding rod 8 to fit different types of aluminum profiles, the position of the limiting plate 24 is adapted to different types of aluminum profiles). The entire section of the aluminum profile is limited, reducing the probability of damage to the clamped parts caused by shaking, thereby ensuring the quality of the aluminum profile after traction.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
