Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile straightening, and more specifically to an aluminum profile straightening machine and an aluminum profile straightening process. Background Art

[0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. Common aluminum profiles are generally square strips of metal materials. Due to their light weight, high strength, corrosion resistance and many other excellent properties, they are widely used in many fields, such as construction, transportation, industry, electronics, etc. Existing aluminum profile straightening machines are classified according to the straightening method: pressure straightening machines and roller straightening machines. Pressure straightening machines mainly straighten by applying pressure to the local part of the aluminum profile. Roller straightening machines work with multiple sets of straightening rollers, which are usually staggered and have a certain spacing and angle.

[0003] For example, the prior art publication number is CN112371767B, which discloses an aluminum profile straightening machine and an aluminum profile processing technology using the straightening machine. The invention straightens the aluminum profile in the process of passing through the straightening die column by cooperating with the straightening die column, a supporting mechanism and a transmission mechanism.

[0004] However, the above-mentioned prior art still has the following problems when in use: the existing aluminum profile straightening machine is long in length, occupies a large area, and uses multiple mold columns for straightening, the surface of the aluminum profile is easily uneven, and it is necessary to frequently stop the machine to replace the mold columns, which wastes some time and leads to low straightening efficiency. Based on this, the present invention provides an aluminum profile straightening machine and an aluminum profile straightening process with high straightening efficiency. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an aluminum profile straightening machine and an aluminum profile straightening process.

[0008] In a preferred embodiment, two electric push rods two are fixedly connected to the top ends of the two U-shaped plates two. The four electric push rods two are fixed to the top of the processing table through the same mounting plate. The position of the two U-shaped plates two is adjusted by means of the electric push rod three to prevent the U-shaped plate two from hindering the rotation of the aluminum profile.

[0009] In a preferred embodiment, the multiple electric clamps on both sides of the rotating frame correspond one by one. A belt conveyor one for conveying and straightening aluminum profiles is fixedly provided at the front end of the processing table, and the rear end of the belt conveyor one extends between the rotating frame and the processing table. A plurality of rubber partition strips are fixedly provided on the conveyor belt surface of the belt conveyor one. The rubber partition strips can be used to separate the multiple aluminum profiles, so as to facilitate the electric clamps to clamp the aluminum profiles.

[0010] In a preferred embodiment, a belt conveyor two is fixedly provided at the rear end of the processing table. The belt conveyor two is located below the rotating frame and is used to convey the straightened aluminum profiles. A limiting frame is fixedly provided at the top of the belt conveyor two, and the top of the limiting frame extends below the rotating frame. The limiting frame can be used to limit the falling aluminum profiles to prevent the aluminum profiles from falling outside the belt conveyor two.

[0011] In a preferred embodiment, a reduction motor for driving the rotation of the rotating frame is provided on one side of the processing table. The reduction motor is fixed to the processing table through a support seat. The reduction motor is used to drive the rotating frame to rotate automatically, so as to improve the straightening efficiency of the aluminum profile.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Referring to the attached drawings of the specification Figure 1-9 , the present invention provides an aluminum profile straightening machine, including a processing table 1. A feeding component 2, a straightening component 3, and a detection component 4 are rotatably connected inside the processing table 1. The feeding component 2 includes a rotating frame 201 rotatably connected inside the processing table 1. A plurality of electric clamps 202 for clamping aluminum profiles are fixedly provided on both inner walls of the rotating frame 201. A reduction motor 10 for driving the rotation of the rotating frame 201 is provided on one side of the processing table 1. The reduction motor 10 is fixed to the processing table 1 through a support seat 11. The reduction motor 10 is used to drive the automatic rotation of the rotating frame 201, thereby improving the straightening efficiency of aluminum profiles.

[0038] The straightening component 3 includes two upper and lower distributed straightening plates one 301 and two front and rear distributed straightening plates two 302. The two straightening plates one 301 and the two straightening plates two 302 are respectively in contact with the four sides of the aluminum profile for extrusion straightening.

[0039] An installation mechanism 5 for adjusting the two straightening plates one 301 and the two straightening plates two 302 is provided on the processing table 1. Specifically, the installation mechanism 5 includes a U-shaped plate one 501 sleeved outside the two straightening plates one 301 and a U-shaped plate two 502 sleeved outside the two straightening plates two 302. At least one electric push rod one 503 is fixedly penetrated on the two U-shaped plates one 501 and the two U-shaped plates two 502. The piston end of the electric push rod one 503 is fixedly connected to the straightening plate one 301 and the straightening plate two 302. The electric push rod one 503 can be used to drive the movement of the straightening plate one 301 and the straightening plate two 302, thereby realizing the automatic adjustment of the aluminum profile.

[0040] Two electric push rods two 504 are fixedly connected to the top ends of the two U-shaped plates two 502. The four electric push rods two 504 are fixed to the top of the processing table 1 through the same mounting plate 505. The position of the two U-shaped plates two 502 is adjusted by means of the electric push rod three 504 to prevent the U-shaped plate two 502 from hindering the rotation of the aluminum profile.

[0041] Next, a plurality of electric clamps 202 located on both sides of the rotary rack 201 correspond one by one. A belt conveyor 6 for conveying and straightening aluminum profiles is fixedly arranged at the front end of the processing table 1, and the rear end of the belt conveyor 6 extends between the rotary rack 201 and the processing table 1. A plurality of rubber partition strips 7 are fixedly arranged on the surface of the conveyor belt of the belt conveyor 6. The rubber partition strips 7 can separate a plurality of aluminum profiles, so as to facilitate the electric clamps 202 to clamp the aluminum profiles.

[0042] Moreover, a belt conveyor 8 is fixedly arranged at the rear end of the processing table 1. The belt conveyor 8 is located below the rotary rack 201 and is used for conveying the straightened aluminum profiles. A limiting frame 9 is fixedly arranged at the top of the belt conveyor 8, and the top of the limiting frame 9 extends below the rotary rack 201. With the help of the limiting frame 9, the falling aluminum profiles can be limited, so as to prevent the aluminum profiles from falling outside the belt conveyor 8.

[0043] Use the belt conveyor 6 to sequentially convey a plurality of aluminum profiles to the front of the rotary rack 201. The electric clamps 202 on the left and right sides of the rotary rack 201 cooperate to clamp the aluminum profiles. Then use the reduction motor 10 to drive the rotary rack 201 to rotate, and convey the aluminum profiles to the straightening assembly 3. At this time, the empty electric clamps 202 continue to clamp the aluminum profiles to be straightened. The electric push rod 504 on the mounting plate 505 first drives the two U-shaped plates 502 to move downward, so that the two straightening plates 302 are located in front of and behind the aluminum profile. Then use the electric push rod 503 to drive the straightening plate 301 and the straightening plate 302 to move and squeeze the aluminum profile, so as to complete the straightening work of the aluminum profile. After straightening, the straightening plate 301 and the straightening plate 302 move away from the aluminum profile. The rotary rack 201 continues to rotate to drive the straightened aluminum profile to move to the detection assembly 4 for detection. The subsequent two groups of electric clamps 202 repeat the feeding and straightening work. Finally, the detected aluminum profiles are sent to the belt conveyor 8. In this embodiment, by concentrating the feeding, straightening, detection and blanking in the processing table 1, the occupied area of the device can be greatly reduced. At the same time, the feeding, straightening, detection and blanking are in a pipeline operation, which can reduce unnecessary downtime, and thus can improve the straightening efficiency of the aluminum profile.

[0044] Refer to the attached drawings of the specification Figure 2-5 The detection assembly 4 includes a fixing plate 401. A fixing groove 402 is opened on the inner wall of one side of the processing table 1. The fixing plate 401 is detachably fixed in the fixing groove 402. A plurality of detachable industrial cameras 403 are fixedly arranged on the fixing plate 401. Through holes 404 with the same number as the industrial cameras 403 are opened on one side of the rotary rack 201 close to the industrial cameras 403.

[0045] To facilitate the distinction between qualified and unqualified aluminum profiles after inspection, a liquid storage tank 12 is fixedly provided on the outer wall of the processing table 1 on the side far from the fixed plate 401. The liquid storage tank 12 stores a coating for marking. The top of the liquid storage tank 12 is connected to a water pump 13. The water outlet of the water pump 13 is connected to a spray head 14. The spray head 14 is fixed on the inner wall of the processing table 1 on the side far from the fixed plate 401. A liquid adding pipe 15 is fixedly penetrated through the top of the liquid storage tank 12 on the side far from the water pump 13. The liquid adding pipe 15 is communicated with the inside of the liquid storage tank 12, and a threaded cover 16 is threadedly connected to the liquid adding pipe 15.

[0046] The industrial camera 403 takes pictures of the straightened aluminum profiles, and then uses image processing software to analyze the images to detect the flatness of the aluminum profiles. When the industrial camera 403 detects that the aluminum profiles are not flat, the water pump 13 sucks the coating in the liquid storage tank 12 and sprays it onto the aluminum profiles through the spray head 14 as a mark, so as to facilitate the subsequent screening of the aluminum profiles with the coating for re-straightening. On the contrary, when the industrial camera 403 detects that the aluminum profiles are flat, the water pump 13 does not operate.

[0047] During actual use, a control box can be installed on the processing table 1 to control the belt conveyor one 6, belt conveyor two 8, reduction motor 10, water pump 13, industrial camera 403, electric push rod one 503, and electric push rod two 504 in the present invention. And the control box is powered by a built-in battery. At the same time, in order to facilitate the remote control of the electric fixture 202, the electric fixture 202 can be connected to the control box through a wireless transmission module to achieve remote control. The electric fixture 202 is powered by its own battery. The above technologies are all commonly used existing technologies and will not be further described here.

[0048] The present invention also provides a process for straightening aluminum profiles using the above straightening machine, and the specific steps are as follows:

[0049] Step 1: Use the belt conveyor one 6 to sequentially convey a plurality of aluminum profiles in front of the rotating frame 201, and the electric fixtures 202 on the left and right sides of the rotating frame 201 cooperate to clamp the aluminum profiles;

[0050] Step 2: Start the reduction motor 10 to drive the rotating frame 201 to rotate, so that the aluminum profiles are conveyed to the straightening assembly 3. At the same time, the empty electric fixture 202 clamps the next aluminum profile to be straightened;

[0051] Step 3: The reduction motor 10 and the belt conveyor one 6 stop operating. The electric push rod two 504 drives the straightening plates two 302 in the two U-shaped plates two 502 to move downward. Then, the two straightening plates one 301 and the two straightening plates two 302 squeeze the aluminum profiles under the drive of their respective electric push rods one 503. After straightening, the two straightening plates one 301 and the two straightening plates two 302 return to their original positions;

[0052] Step 4: The rotating frame 201 continues to rotate to drive the straightened aluminum profile to the detection component 4 for detection. The detected aluminum profile is sent to the belt conveyor 2 8 to obtain the straightened aluminum profile.

[0053] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
