Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and in particular to an aluminum profile stretching and straightening machine. Background Technology

[0002] Aluminum profiles are one of the most widely used non-ferrous metal structural materials in industry. Using aluminum as the base material, they are processed into profile structures of different specifications and shapes according to different usage requirements. They are widely used in many fields such as aerospace, automobiles, machinery manufacturing, and construction. During production, a tension straightening machine is used to straighten the aluminum profiles after initial cooling to ensure the flatness of the profiles.

[0003] Existing aluminum profile stretching and straightening machines have the following drawbacks: When using a stretching and straightening machine to straighten aluminum profiles, the amount of stretching is generally determined by controlling the displacement of the machine's clamps. After stretching, the profiles need to be removed from the straightening machine for subsequent inspection. However, the straightening machine lacks equipment for initial inspection of the profile's straightness, resulting in low inspection efficiency. Therefore, we propose an aluminum profile stretching and straightening machine. Utility Model Content

[0004] The main purpose of this utility model is to provide an aluminum profile stretching and straightening machine. Through a calibration mechanism, the flatness of the profile can be initially detected during the operation of the stretching and straightening machine, thereby improving detection efficiency, reducing subsequent detection procedures, and effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An aluminum profile stretching and straightening machine includes a frame and a calibration mechanism. The calibration mechanism is located on the top of the frame and includes a support plate, a hollow cover, a base plate, a spring, a connecting seat, a top plate, conductive sheet A, conductive sheet B, and indicator lights. The support plates are spaced apart inside the frame, and the hollow covers are fixed to the top of the support plates by fasteners. The base plates are horizontally installed inside the hollow covers, and the connecting seats are movably connected to the top of the base plates by springs. The top plate of the connecting seat extends to the top of the frame. A conductive sheet B is adhered to one side of the bottom of the connecting seat, and a conductive sheet A corresponding to the position of conductive sheet B is installed on the top of the base plate. Indicator lights are installed on the sides of the frame at positions corresponding to the support plates.

[0007] Furthermore, it also includes an adjustment mechanism. An adjustment mechanism is provided between the support plate and the base plate. The adjustment mechanism includes screw holes B and bolts B. Screw holes B are vertically opened at the center position inside the base plate. Bolts B are screwed into the base plate through the screw holes B, and the top of bolts B is connected to the center position of the base plate. The connecting seat is fixed to the top of the base plate by springs. The base plate is neatly placed inside the hollow cover, and the base plate and the support plate are connected by bolts B. Before performing tensile testing, bolts B can be turned along the screw holes B. When bolts B are turned, the height of the base plate is adjusted, thereby adjusting the height position of the top plate. When the spring length changes after long-term use, the change in spring length can be compensated by adjusting the height position of the top plate. The accuracy of the calibration mechanism can be ensured by testing and calibrating the height of each set of top plates before the testing operation.

[0008] Furthermore, a positioning clamp is slidably connected to one side of the top of the frame, and a hydraulic cylinder is installed at the end of the top of the frame away from the positioning clamp, with the power output end of the hydraulic cylinder connected to the movable clamp via a connecting plate; the profile to be straightened is moved into the top of the frame with the convex surface facing upward, and both ends are fixed by the positioning clamp and the movable clamp respectively. The positioning clamp is hung inside the frame by a hook to keep its position fixed, and the operation of the hydraulic cylinder drives the movement of the movable clamp to achieve the stretching and straightening of the profile.

[0009] Furthermore, a screw hole A is vertically opened on one side of the base plate, and a bolt A is screwed into the screw hole A. The top of the bolt A is connected to the bottom of the conductive sheet A. Tightening the bolt A along the screw hole A can adjust the height of the conductive sheet A, thereby adjusting the position of the conductive component according to the ground height after the profile is straightened.

[0010] Furthermore, the current input terminal of the indicator light is electrically connected to an external circuit through conductive sheet A and conductive sheet B; both conductive sheet A and conductive sheet B are installed through insulating components, and when the two are in contact, the power supply circuit of the indicator light is turned on, thereby energizing and lighting up.

[0011] Furthermore, an end ring is welded to the top of the bolt B, and the end rings are located on the upper and lower sides of the base plate surface respectively; the end ring structure is located on both sides of the base plate and the bolt B penetrates the base plate, so that when the bolt B is tightened, the end ring rotates, which can drive the vertical height adjustment of the base plate.

[0012] Compared with the prior art, this utility model has the following beneficial effects: The profile to be straightened is moved into the top of the frame with the convex surface facing upwards. Both ends are fixed by positioning clamps and movable clamps respectively. The positioning clamps are hung inside the frame by hooks to keep their positions fixed. The hydraulic cylinder drives the movable clamps to move, thereby achieving the stretching and straightening of the profile. The frame is equipped with a calibration structure, the main body of which is a hollow cover and a top plate structure. Before use, each set of calibration structures is adjusted so that the height of the top plate after the conductive sheets are attached is exactly the height of the bottom surface of the straightened aluminum profile. Before processing, the spring pushes the connecting seat and the top plate upwards, causing conductive sheet A and conductive sheet B to separate, and the indicator light is in the open circuit state. During the straightening of the aluminum profile, each section of the profile is slowly deformed and straightened. If it is straightened to the correct position, its bottom will press down on the top plate, so that conductive sheet B and conductive sheet A are aligned. Contacting the indicator light illuminates the corresponding position. By observing the illumination of indicator lights at different positions on the side of the frame, a preliminary inspection and judgment of the straightening status of the aluminum profile can be made to ensure that the profile is straightened in place. Subsequent inspections only require random sampling of the straightened profiles, reducing the time spent on subsequent inspection processes and expanding the functionality of the straightening machine. The connecting seat is fixed to the top of the base plate by a spring. The base plate is neatly placed inside the hollow cover, and the base plate and the support plate are connected by bolt B. Before performing tensile testing, bolt B can be turned along the screw hole B. Turning bolt B will adjust the height of the base plate, thereby adjusting the height of the top plate. When the spring length changes after long-term use, the change in spring length can be compensated by adjusting the height of the top plate. Before the inspection, the height of each set of top plates can be inspected and calibrated to ensure the accuracy of the calibration mechanism. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-4 As shown, an aluminum profile stretching and straightening machine includes a frame 1 and a calibration mechanism 3. The calibration mechanism 3 is located on the top of the frame 1. The calibration mechanism 3 includes a support plate 301, a hollow cover 302, a base plate 303, a spring 304, a connecting seat 305, a top plate 306, conductive sheet A309, conductive sheet B310, and an indicator light 311. Support plates 301 are spaced apart inside the frame 1, and the hollow cover 302 is fixed to the top of each support plate 301 by fasteners. Inside the hollow cover 302, a base plate 303 is horizontally installed, and the top of the base plate 303 is movably connected to a connecting seat 305 via a spring 304. A top plate 306 extending to the top of the frame 1 is installed on the top of the connecting seat 305. A conductive sheet B310 is adhered to one side of the bottom of the connecting seat 305, and a conductive sheet A309 corresponding to the position of the conductive sheet B310 is installed on the top of the base plate 303. Indicator lights 311 are installed on the side of the frame 1 at positions corresponding to the support plate 301.

[0020] The system also includes an adjustment mechanism 4, which is provided between the support plate 301 and the base plate 303. The adjustment mechanism 4 includes screw holes B401 and bolts B402. Screw holes B401 are vertically opened at the center of the interior of the base plate 303. Bolts B402 are screwed into the interior of the base plate 303 through the screw holes B401, and the top of the bolts B402 is connected to the center of the base plate 303. The connecting seat 305 is fixed to the top of the base plate 303 by springs 304. The base plate 303 is neatly placed inside the hollow cover 302. 303 is connected to the support plate 301 by bolt B402. Before performing tensile testing, bolt B402 can be turned along the bolt hole B401. When bolt B402 is turned, the height of the base plate 303 is adjusted, thereby adjusting the height of the top plate 306. When the length of the spring 304 changes after long-term use, the change in the length of the spring 304 can be compensated by adjusting the height of the top plate 306. By testing and calibrating the height of each set of top plates 306 before the testing operation, the accuracy of the calibration mechanism 3 can be ensured.

[0021] The frame 1 is slidably connected to a positioning clamp 2 on one side of its top. A hydraulic cylinder 201 is installed at the top of the frame 1 away from the positioning clamp 2, and the power output end of the hydraulic cylinder 201 is connected to the movable clamp 202 through a connecting plate. The profile to be straightened is moved into the top of the frame 1 with the convex surface facing upward. Both ends are fixed by the positioning clamp 2 and the movable clamp 202 respectively. The positioning clamp 2 is hung inside the frame 1 by a hook to keep its position fixed. The operation of the hydraulic cylinder 201 drives the movement of the movable clamp 202 to achieve the stretching and straightening of the profile.

[0022] The base plate 303 has a vertically oriented screw hole A307 on one side, through which a bolt A308 is screwed. The top of the bolt A308 is connected to the bottom of the conductive sheet A309. The current input terminal of the indicator light 311 is electrically connected to the external circuit through the conductive sheets A309 and B310. Tightening the bolt A308 along the screw hole A307 can adjust the height of the conductive sheet A309, thereby adjusting the position of the conductive component according to the ground height after the profile is straightened. Both the conductive sheet A309 and the conductive sheet B310 are installed through insulating components. When the two are in contact, the power supply circuit of the indicator light 311 is connected, and the light is turned on.

[0023] The bolt B402 has an end ring 403 welded to its top. The end ring 403 is located on the upper and lower sides of the surface of the base plate 303. The end ring 403 is located on both sides of the base plate 303 and the bolt B402 passes through the base plate 303. When the bolt B402 is turned, the end ring 403 rotates, which can drive the vertical height adjustment of the base plate 303.

[0024] It should be noted that this utility model is an aluminum profile stretching and straightening machine. During use, the profile to be straightened is moved to the top of the frame 1 with the convex surface facing upwards. Both ends are fixed by positioning clamps 2 and movable clamps 202, respectively. The positioning clamps 2 are hung inside the frame 1 by hooks to maintain their position. The hydraulic cylinder 201 drives the movable clamps 202 to move, thus achieving the stretching and straightening of the profile. The frame 1 has a calibration structure inside, the main body of which is a hollow cover 302 and a top plate 306. Before use, each... The calibration structure is adjusted so that the top of the top plate 306 is at the same height as the bottom of the straightened aluminum profile after the conductive sheets are attached. Before processing, the spring 304 pushes the connecting seat 305 and the top plate 306 upwards, causing the conductive sheets A309 and B310 to separate, and the indicator light 311 is in an open circuit state. During the straightening of the aluminum profile, each section of the profile is slowly deformed and straightened. If it is straightened to the correct position, its bottom will press down on the top plate 306, so that the conductive sheet B310 and the conductive sheet A309 are connected. Touching the indicator light 311 illuminates the corresponding position. By observing the illumination of the indicator lights 311 at different positions on the side of the frame 1, a preliminary inspection and judgment of the straightening status of the aluminum profile can be made to ensure that the profile is straightened in place. Subsequent inspections only require random sampling of the straightened profile, reducing the time spent on subsequent inspection processes and expanding the functionality of the straightening machine. The connecting seat 305 is fixed to the top of the base plate 303 by the spring 304. The base plate 303 is neatly placed inside the hollow cover 302, and there is a connection between the base plate 303 and the support plate 301. Connected by bolt B402, before performing tensile testing, bolt B402 can be turned along bolt hole B401. When bolt B402 is turned, the height of base plate 303 is adjusted, thereby adjusting the height of top plate 306. After long-term use, when the length of spring 304 changes, the change in the length of spring 304 can be compensated by adjusting the height of top plate 306. By testing and calibrating the height of each set of top plates 306 before testing, the accuracy of calibration mechanism 3 can be ensured.
