Description

Technical Field

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

[0002] Aluminum profiles are widely used in high-end fields such as aerospace and rail transportation due to their light weight, high strength and corrosion resistance. These fields have strict requirements for the straightness and dimensional accuracy of aluminum profiles. In particular, long profiles are prone to bending, twisting or drooping at the ends due to uneven stress distribution during rolling, extrusion and cooling processes, which need to be corrected by straightening process. Traditional aluminum profile straightening equipment mostly adopts a fixed clamping structure. For profiles with drooping ends, manual assistance is required to lift and align them, which not only increases labor intensity but also easily leads to secondary deformation due to uneven force. Some equipment requires additional auxiliary structures for lifting, which is more complex and occupies extra space, resulting in poor practicality. At the same time, the clamping mechanism is mostly a single jaw design, which is difficult to adapt to profiles with irregular cross-sections, often resulting in clamping slippage or surface damage, affecting the product qualification rate. With the increasing quality requirements of high-end manufacturing for aluminum profiles, the shortcomings of existing equipment in terms of automation, adaptability, and precision control are becoming increasingly prominent. There is an urgent need to develop a new type of straightening unit with adaptive clamping and precise adjustment functions. Utility Model Content

The first cylinder is vertically installed inside the fixed clamp and the movable clamp. The movable seat is connected to the output end of the first cylinder, and the bottom of the lower clamping plate is fixed to the upper end of the movable seat.

[0005] Preferably, the adjustment assembly includes a movable groove, an auxiliary clamp, a rotating shaft, a second cylinder, and a mounting base. The movable groove is formed on the inner wall of the upper clamp. The auxiliary clamp is rotatably connected to the bottom of the movable groove via the rotating shaft. The piston end of the second cylinder is rotatably connected to the inner side of the auxiliary clamp via the mounting base.

[0006] Preferably, the fixed clamp and the movable clamp are respectively provided with embedded grooves, the first cylinder is fixed at the bottom of the embedded groove, and the movable seat is movably located at the upper end of the embedded groove.

[0008] Preferably, pressure sensors are embedded in the clamping surfaces of both the upper clamp and the auxiliary clamp, and the pressure sensors are electrically connected to the unit control system.

[0015] 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.

[0016] like Figure 1-4 As shown, this embodiment provides an aluminum profile double-column straightening machine, including a conveyor belt 1, a guide rail 2, a fixed clamp 3, a movable clamp 4, a lifting component 6, and an adjusting component 7. The fixed clamp 3 and the movable clamp 4 are respectively set at both ends of the guide rail 2. The conveyor belt 1 is transversely set between the fixed clamp 3 and the movable clamp 4. The upper inner end of both the fixed clamp 3 and the movable clamp 4 is provided with an upper clamp 5. The lifting component 6 is set at the lower inner end of the fixed clamp 3 and the movable clamp 4. The adjusting component 7 is set inside the upper clamp 5. The bottom of the movable clamp 4 is provided with a sliding seat adapted to the guide rail 2. A ball screw transmission mechanism driven by a servo motor is installed at one end of the guide rail 2. The movable clamp 4 is connected to the ball screw through a nut seat to realize high-precision linear displacement adjustment along the guide rail 2. In this embodiment, the lifting assembly 6 includes a movable seat 61, a lower clamping plate 62, and a first cylinder 63. The first cylinder 63 is vertically installed inside the fixed clamp 3 and the movable clamp 4. The movable seat 61 is connected to the output end of the first cylinder 63. The bottom of the lower clamping plate 62 is fixed to the upper end of the movable seat 61. The fixed clamp 3 and the movable clamp 4 are respectively provided with an embedded groove 41. The first cylinder 63 is fixed to the bottom of the embedded groove 41. The movable seat 61 is movably located at the upper end of the embedded groove 41. Four sets of guide rods 65 are fixed to the lower end of the movable seat 61. Four sets of guide sleeves 6 corresponding to the guide rods 65 are fixed in the embedded groove 41. 4. The lower end of the guide rod 65 is movably inserted into the guide sleeve 64. The first cylinder 63 drives the movable seat 61 and the lower clamping plate 62 to rise and fall. The guide sleeve 64 and the guide rod 65 provide vertical guidance for the lower clamping plate 62, enabling the adjustment of the lower clamping plate 62. This facilitates the adaptation and support of the drooping part of the aluminum profile end, reduces manual intervention, lowers the labor intensity of operators, avoids operational errors caused by manual adjustment, effectively improves the efficiency of straightening operations and the finished product qualification rate, and adapts to aluminum profile ends with different degrees of drooping, enhancing the equipment's adaptability to diverse processing needs.

[0017] In this embodiment, the adjustment component 7 includes a movable groove 71, an auxiliary clamp 72, a rotating shaft 73, a second cylinder 74, and a mounting base 75. The movable groove 71 is located on the inner wall of the upper clamp 5. The auxiliary clamp 72 is rotatably connected to the bottom of the movable groove 71 via the rotating shaft 73. The piston end of the second cylinder 74 is rotatably connected to the inner side of the auxiliary clamp 72 via the mounting base 75. The bottom of the second cylinder 74 is rotatably connected to the inner side of the movable groove 71 via the mounting base 75. Pressure sensors 8 are embedded in the clamping surfaces of both the upper clamp 5 and the auxiliary clamp 72. The pressure sensors 8 are electrically connected to the unit control system. The second cylinder 74 drives the auxiliary clamp 72 to rotate within the movable groove 71. The auxiliary clamp 72 assists in clamping the aluminum profile, enabling dual clamping and fixing of aluminum profiles of different sizes. This further maintains the stability of the aluminum profile during stretching and prevents slippage, displacement, or local deformation during the stretching process. The angle of the auxiliary clamp 72 can be adjusted to form multi-contact clamping, significantly improving the equipment's adaptability to complex profiles and the stability of processing quality.

[0018] The working principle and process of this utility model are as follows: During use, the aluminum profile is conveyed by the conveyor belt 1 to the space between the fixed clamp 3 and the movable clamp 4. The first cylinder 63 of the lifting component 6 drives the movable seat 61 and the lower clamping plate 62 to rise and fall. Under the vertical guidance of the guide rod 65 and the guide sleeve 64, the profile's drooping end is precisely fitted and supported. At the same time as the upper clamp 5 closes, the second cylinder 74 of the adjusting component 7 drives the auxiliary clamp 72 to rotate around the rotating shaft 73, forming a multi-contact clamping. The pressure sensor 8 monitors the clamping force in real time and feeds it back to the control system for dynamic adjustment. Subsequently, the servo motor drives the ball screw, which drives the movable clamp 4 to move smoothly along the guide rail 2, applying a controllable tensile force to the profile. The straightening operation is completed through high-precision displacement adjustment. The entire process is automated, efficiently adapting to aluminum profiles of different specifications and bending states, ensuring stable processing quality.
