Description

Technical Field

[0001] This invention relates to the field of aluminum alloy measuring equipment technology, and in particular to a device and method for measuring the cooling rate of extruded aluminum alloy profiles. Background Technology

[0002] Currently, Chinese Patent Publication No. CN115753884A discloses a device and method for measuring the cooling rate of aluminum alloy extruded profiles. The device includes a protective shell with an internal cavity; a data processing module housed within the cavity; and a temperature measuring device mounted on the protective shell, with its detection point located on the outside of the shell. The temperature measuring device is electrically connected to the data processing module. This discloses a conventional measuring device, but when cooling long, strip-shaped profiles, the existing temperature measuring device is easily dislodged from the profiles due to the influence of the exhaust fan as it passes through the cooling box, and the violent shaking of the internal profiles. Some adjacent profiles may come into contact with each other. Summary of the Invention

[0003] Therefore, in view of the above problems, the present invention proposes an apparatus and method for measuring the cooling rate of aluminum alloy extruded profiles. It solves the technical problem that when cooling long strip profiles, due to the influence of the exhaust fan and the violent shaking of the internal profiles as they pass through the cooling box, some adjacent profiles will come into contact with each other, and the existing temperature measuring device is easily thrown off the profile.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a device for measuring the cooling rate of aluminum alloy extruded profiles, comprising a cooling box, a condenser disposed on the side of the cooling box, multiple exhaust fans disposed on the top of the cooling box, an inlet disposed on the front end of the cooling box, an outlet disposed on the rear end of the cooling box, and an S-shaped conveying channel disposed inside the cooling box. The multiple exhaust fans are arranged in a horizontal row, and the S-shaped conveying channel is located below the horizontal row of exhaust fans. A clamping device for clamping the profile is provided at the inlet of the cooling box, and a clamping detection device for the profile is also provided at the inlet of the cooling box. The detection device includes a support plate, a square hole in the middle of the support plate, protruding posts on the support plate and located on both sides of the square hole, a rocker arm hinged to the protruding posts, a first crossbar rotatably disposed on one side of the two rocker arms, a second crossbar rotatably disposed on the other side of the two rocker arms, a threaded hole on one side of the support plate, a stud screwed into the threaded hole and in contact with the first crossbar, a fixed post on the other side of the crossbar, a spring between the second crossbar and the second fixed post, a control plate at the bottom of the support plate, an extension post on the support plate, and a temperature sensor on the extension post.

[0005] Furthermore, a first elastic element is provided between the temperature sensor and the extension column.

[0006] Furthermore, the S-shaped conveying channel includes multiple connecting rods disposed within the housing, a guide sleeve detachably disposed at the bottom of the connecting rods, an opening disposed at the bottom of the guide sleeve, a guide chain disposed within the relevant sleeve, and a connecting piece disposed within the guide chain.

[0007] Furthermore, the guide chain includes multiple horizontal pieces, vertical pieces rotatably disposed between adjacent horizontal pieces, horizontal rotating wheels rotatably disposed between the horizontal pieces, and vertical rotating wheels rotatably disposed on the front and rear sides of the vertical pieces. The outer side of the horizontal rotating wheel is in contact with the two lateral sides of the guide tube sleeve, and the connecting piece is rotatably disposed on the front and rear sides of the vertical rotating wheel.

[0008] Furthermore, the diameter of the vertical rotating wheel gradually decreases from one side to the other, and the shape of the vertical rotating wheel is conical.

[0009] Furthermore, the inner wall of the guide sleeve has a smooth surface, and a connecting flange is provided between the guide sleeves.

[0010] A method for measuring the cooling rate of extruded aluminum alloy profiles includes the following steps:

[0011] The first step involves the S-shaped conveyor channel feeding in the external profiles. After being fed into the inlet, the clamping device secures the profiles.

[0012] The second step is to pass the square hole on the support plate through the bottom of the profile, and then rotate the stud. The stud rotates to the side of the square hole, and the stud drives the first crossbar to move to the right. The second crossbar swings through the swing arm, and the distance between the first crossbar and the second crossbar decreases. The first rubber block on the first crossbar and the second rubber block on the second crossbar will clamp and fix the bottom of the profile.

[0013] Third, since the extension column on the support plate is close to the profile, the temperature sensor will send the detected temperature signal to the control board, which will record the profile cooling temperature data.

[0014] By adopting the aforementioned technical solution, the beneficial effects of the present invention are:

[0015] This device for measuring the cooling rate of aluminum alloy extruded profiles uses an S-shaped conveying channel to input the external profile. After being conveyed to the input port, the profile is fixed by a clamping device. Then, a square hole on the support plate passes through the bottom of the profile. The stud is rotated, turning towards the square hole. The stud drives the first crossbar to move to the right, and the second crossbar swings through the swing arm, reducing the distance between the first and second crossbars. The first rubber block on the first crossbar and the second rubber block on the second crossbar clamp and fix the bottom of the profile. The extension column on the support plate is close to the profile, and the temperature sensor sends the detected temperature signal to the control board, which records the profile cooling temperature data. Compared with the existing spring clamping mechanism, which is prone to slippage and loosening, this mechanism has good stability and solves the technical problem that when cooling long strip profiles, due to the influence of the exhaust fan and the violent shaking of the internal profiles, some adjacent profiles will come into contact with each other, and the existing temperature measuring device is easily thrown off the profile.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0031] refer to Figures 1 to 14 This embodiment provides a device for measuring the cooling rate of aluminum alloy extruded profiles, including a cooling box 1, a condenser 2 located on the side of the cooling box 1, multiple exhaust fans 3 located on the top of the cooling box 1, an inlet 4 located at the front end of the cooling box 1, an outlet 5 located at the rear end of the cooling box 1, and an S-shaped conveying channel 6 located inside the cooling box 1. The multiple exhaust fans 3 are arranged in a horizontal row, and the S-shaped conveying channel 6 is located below the horizontal row of exhaust fans 3. The inlet 4 of the cooling box 1 is provided with a clamping device 7 for clamping the profile, and the inlet 4 of the cooling box 1 is provided with a detection device 8 for detecting the clamping of the profile.

[0032] The detection device 8 includes a support plate 801, a square hole 802 in the middle of the support plate 801, protruding posts 803 on the support plate 801 and located on both sides of the square hole 802, a rocker arm 804 hinged to the protruding post 803, a first crossbar 805 rotatably disposed on one side of the two rocker arms 804, a second crossbar 806 rotatably disposed on the other side of the two rocker arms 804, a threaded hole 807 on one side of the support plate 801, a stud 808 screwed into the threaded hole 807 and in contact with the first crossbar 805, a fixed post 809 on the other side of the crossbar, a spring 810 between the second crossbar 806 and the second fixed post 809, a control plate 811 at the bottom of the support plate 801, an extension post 812 on the support plate 801, and a temperature sensor 813 on the extension post 812. A first motor 8a for driving the stud to rotate is provided on one side of the support plate.

[0033] Through the setting of the detection device 8, the external profile is input through the S-shaped conveying channel 6. After being conveyed to the input port 4, the clamping device 7 fixes the profile. Then, the square hole 802 on the support plate 801 is passed through the bottom of the profile. Then, the stud 808 is rotated, and the stud 808 rotates to the side of the square hole 802. The stud 808 drives the first crossbar 805 to move to the right. The second crossbar 806 is swung by the swing rod 804, and the distance between the first crossbar 805 and the second crossbar 806 decreases. The first rubber block on the first crossbar 805 and the second crossbar 806... The second rubber block on the crossbar 806 will clamp and fix the bottom of the profile. Since the extension column 812 on the support plate 801 is close to the profile, the temperature sensor 813 will send the detected temperature signal to the control board 811, which will record the profile cooling temperature data. Compared with the existing clamping mechanism that relies on spring 810, which is prone to slippage and loosening, this mechanism has good stability. When disassembly is required, the stud is rotated in the opposite direction. Under the action of the spring, one side of the first crossbar will always be in contact with the stud, and the distance between the first crossbar and the second crossbar will increase, allowing it to fall off the profile.

[0034] A first elastic element 814 is provided between the temperature sensor 813 and the extension post 812. Due to the certain tolerance of the profile, the first elastic element 814 will keep the temperature sensor 813 in contact with the profile so that it will always be attached to the surface of the profile, thereby improving the detection accuracy.

[0035] The S-shaped conveying channel 6 includes multiple connecting rods 601 disposed in the housing, a guide sleeve 602 detachably disposed at the bottom of the connecting rods 601, an opening 603 disposed at the bottom of the guide sleeve 602, a guide chain disposed inside the relevant sleeve, and a connecting piece 604 disposed inside the guide chain.

[0036] The S-shaped conveying channel is designed with guide pipes distributed at the bottom of the fan. The bottom of the connecting plate is used to lift the profile through an external hook. An external drive gear drives the guide chain to move. During the movement of the guide chain, the guide sleeve moves along with the guide sleeve. Since the guide sleeve is located at the connection between the front and rear of the horizontal fan, it can be made into a curved shape. The guide chain will bend along with the guide sleeve and move in an S-shaped trajectory. During the movement of the guide chain, the bottom profile will be driven through each fan, which is good for the heat dissipation performance of the profile.

[0037] The guide chain includes multiple horizontal plates 605, vertical plates 606 rotatably disposed between adjacent horizontal plates 605, horizontal rotating wheels 607 rotatably disposed between the horizontal plates 605, and vertical rotating wheels 608 rotatably disposed on the front and rear sides of the vertical plates 606. The outer side of the horizontal rotating wheel 607 is in contact with the two lateral sides of the guide sleeve 602. The connecting piece 604 is rotatably disposed on the front and rear sides of the vertical rotating wheel 608. The diameter of the vertical rotating wheel 608 gradually decreases from one side to the other. The vertical rotating wheel 608 is conical in shape.

[0038] The guide chain is designed so that the vertical rollers on the front and rear sides of the vertical plate are in contact with the upper and lower side walls of the guide sleeve. Since the vertical rollers are conical, they will move in contact with the inner wall of the guide sleeve, allowing for smooth movement even when moving in a curved guide pipe. At the same time, the horizontal rollers on the upper and lower sides of the horizontal plate will be in contact with the front and rear side walls of the guide sleeve, guiding the movement of multiple horizontal and vertical plates. The movement is more stable, and the horizontal and vertical plates have good load-bearing capacity, with smooth movement of the horizontal and vertical rollers.

[0039] The inner wall of the guide sleeve 602 has a smooth surface. A connecting flange 6a is provided between the guide sleeves 602. Since the guide sleeve needs to be spliced ​​into multiple sections, the two ends of the guide sleeve are welded and fixed with connecting flanges. The connecting flanges of the two sections of the guide sleeve are locked with bolts, which is conducive to assembling the guide sleeve.

[0040] The clamping device 7 includes connecting blocks 71 on both sides of the input port, a first clamping block 72 on one side of the input port connecting block 71, a second clamping block 73 on the other side of the input port connecting block 71, a first driving cylinder 74 for driving the first clamping block 72 to move, and a second driving cylinder 75 for driving the second clamping block 73 to move. The first clamping block 72 and the second clamping block 73 are V-shaped. The first clamping block 72 is arranged in two layers with an interval between them. The height of the second clamping block 73 is located between the upper and lower sides of the first clamping block 72.

[0041] When the S-shaped conveyor channel transports the profile to the inlet, it stops moving. Then, the first drive cylinder 74 and the second drive cylinder 75 drive the first clamping block 72 and the second clamping block 73 to move towards the center, respectively. The first clamping block 72 and the second clamping block 73 come into contact with the profile. Since the first clamping block 72 and the second clamping block 73 are V-shaped, the profile will be centered and positioned above the square hole in the center of the support plate. After the detection device is fixed to the profile, the first drive cylinder 74 and the second drive cylinder 75 will drive the first clamping block 72 and the second clamping block 73 to separate to both sides and not come into contact with the profile.

[0042] The cooling box 1 has an inlet 4 equipped with a drive mechanism 9 for lifting and moving the detection device 8. The drive mechanism 9 includes a base 901, guide rods 902 fixed on both sides of the front end of the base 901, a slider 903 slidably disposed on the outside of the guide rods 902, a second elastic element 904 disposed between the slider 903 and the base 901, a guide shaft 905 rotatably disposed in the middle of the base 901, a guide groove 906 disposed on the outside of the guide shaft 905, long rods 907 disposed on both sides of the top surface of the slider 903, a support block 908 disposed on the top of the long rods 907, and a second motor 909 for driving the guide shaft 905 to rotate. Half of the guide groove 906 is an arc-shaped groove that slopes from top to bottom, and the other half of the guide groove 906 is an arc-shaped groove that slopes from bottom to top. The slider is slidably connected to the guide groove.

[0043] When the S-shaped conveyor channel transports the profile into the input port, the clamping device clamps and fixes the profile. The second motor drives the guide shaft to rotate. At this time, the arc groove on one side from bottom to top contacts the slider, which will drive the slider to move upward. Under the action of the second elastic element, the slider will quickly drive the long rod and support block to move upward. Since the detection device is located on the support block, it will quickly connect with the profile. After completion, the second motor continues to drive the guide shaft to rotate. At this time, the other half of the guide groove from top to bottom contacts the slider. When the slider moves down halfway, the long rod and support block move down and do not contact the profile. A new detection device can be placed on the support block by an external robot. When the second motor drives the slider on the guide shaft to the bottom, the newly input profile is input above the drive mechanism. The reciprocating operation of the second motor can continuously install the detection device on the input profile without manual clamping.

[0044] A method for measuring the cooling rate of extruded aluminum alloy profiles includes the following steps:

[0045] In the first step, the S-shaped conveying channel 6 inputs the external profile, and after it is conveyed to the input port 4, the clamping device 7 fixes the profile.

[0046] The second step is to pass the square hole 802 on the support plate 801 through the bottom of the profile, and then rotate the stud 808. The stud 808 rotates to the side of the square hole 802. The stud 808 drives the first crossbar 805 to move to the right. The second crossbar 806 swings through the swing rod 804. The distance between the first crossbar 805 and the second crossbar 806 decreases. The first rubber block on the first crossbar 805 and the second rubber block on the second crossbar 806 will clamp and fix the bottom of the profile.

[0047] Third, since the extension column 812 on the support plate 801 is close to the profile, the temperature sensor 813 sends the detected temperature signal to the control board 811, which records the profile cooling temperature data.
