Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile production technology, specifically the auxiliary equipment after aluminum profile extrusion. Background Technology

[0002] Aluminum profiles are alloy materials with aluminum as the main component. They are widely used in many fields such as construction, automobiles, aerospace, and electronics. The auxiliary equipment after aluminum profile extrusion is an indispensable part of the aluminum profile production process. It mainly includes quenching equipment, traction machine, hot sawing equipment, cooling bed, straightening machine, finished product saw feed shaft, finished product sawing equipment, and length-fixing table.

[0003] Chinese Patent Application No. 202421148436.0 discloses a material pushing device and its traction mechanism, including a transport mechanism, a pushing mechanism, and a clamping mechanism. The transport mechanism includes a transport frame, an adsorption component, a sliding frame, a limiting component, and a driving component. The transport frame is slidably connected to the sliding frame, the transport frame is connected to the adsorption component, the sliding frame is connected to the limiting component, the driving component is connected to the sliding frame, and the driving component is drivenly connected to the transport frame. The clamping mechanism is connected to the sliding frame. The pushing mechanism includes a positioning component, a pushing plate, and a pushing frame. The pushing frame is slidably connected to the transport frame, the pushing plate is connected to the pushing frame, the positioning component is connected to the pushing frame, and the limiting component is locked to the pushing frame. The material pushing device, by incorporating the transport mechanism, the pushing mechanism, and the clamping mechanism, allows the clamping mechanism to release the aluminum profile after completing the traction process. Simultaneously, the adsorption component abuts against the positioning component, adsorbing the positioning component, thereby preventing the pushing plate from being driven by the clamping mechanism.

[0004] However, the above-mentioned feeding device and its traction machine have the following shortcomings in actual use: During the production process of aluminum profiles, an oxide scale will form on the surface. When the traction machine clamps the material, the friction between the chuck and the surface of the aluminum profile may cause the oxide scale to fall off locally, forming debris. The debris adhering to the chuck will aggravate the friction between the chuck and the surface of the aluminum profile, accelerate the wear of the chuck, shorten the service life of the chuck, and increase the maintenance cost of the equipment. The presence of debris may cause uneven clamping force between the chuck and the aluminum profile, causing the aluminum profile to slip or deviate during the traction process, affecting the traction accuracy, and thus affecting the quality of subsequent processing steps.

[0005] Therefore, auxiliary equipment for the extrusion of aluminum profiles is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background section, this utility model provides an auxiliary machine for aluminum profile extrusion, which has the advantage of cleaning debris adhering to the clamps and avoiding impact on the traction machine.

[0007] To achieve the above objectives, this utility model provides the following technical solution: auxiliary equipment for aluminum profile extrusion, including a quenching device, a traction machine, a hot saw, a cooling bed, a straightening machine, a finished product saw feed shaft, a finished product saw, and a length-fixing table arranged along the aluminum profile discharge processing direction at the rear of the extrusion press. The traction machine includes a conveyor frame, on which a lifting and rotating assembly is installed. The lifting and rotating assembly is connected to a mounting bracket, on which a clamping assembly is installed. A cleaning assembly is provided on the conveyor frame at a position corresponding to the clamping assembly.

[0008] The cleaning assembly includes a fan, the inlet of which is connected to a chip collection box via a pipe, the inlet of which is connected to a U-shaped pipe, the U-shaped pipe to a rotary joint, the rotary joint to a rotating pipe, the rotating pipe to a fixedly connected first driven gear, the first driven gear meshing with a first driving gear, the first driving gear to a first motor via a motor shaft, the rotating pipe to which multiple equidistant air intakes are installed, and the rotating pipe to which multiple evenly distributed cleaning brushes are fixedly connected.

[0010] Preferably, a first fixed frame is fixed on the conveyor frame, the cylinder is mounted on the first fixed frame, a second fixed frame is fixed on the lifting frame, and the second motor is mounted on the second fixed frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model sets up a cleaning component, which moves the chuck and pad to the position of the cleaning component. The cleaning brush and negative pressure adsorption structure clean the debris on the chuck and pad, avoiding aggravating the friction between the chuck and the aluminum profile surface, and also avoiding uneven clamping force between the chuck and the aluminum profile, which would cause the aluminum profile to slip or deviate during the traction process.

[0016] 2. By setting up a lifting and rotating component, this utility model can drive the clamping component to lift and rotate at a certain angle, which can make the clamping of aluminum profiles more accurate.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 6 As shown, this utility model provides auxiliary equipment for aluminum profile extrusion, including a quenching device, a traction machine, a hot saw, a cooling bed, a straightening machine, a finished product saw feed shaft, a finished product saw, and a fixed length table arranged at the rear of the extruder along the aluminum profile discharge processing direction. The traction machine includes a conveyor frame 1, a lifting and rotating assembly 2 installed on the conveyor frame 1, a mounting bracket 3 connected to the lifting and rotating assembly 2, a clamping assembly 4 installed on the mounting bracket 3, and a cleaning assembly 5 provided on the conveyor frame 1 at a position corresponding to the clamping assembly 4.

[0031] The cleaning component 5 includes a fan 51. The inlet of the fan 51 is connected to a chip collection box 52 via a pipe. The inlet of the chip collection box 52 is connected to a U-shaped pipe 53. The U-shaped pipe 53 is connected to a rotary joint 54. The rotary joint 54 is connected to a rotary pipe 55. The rotary pipe 55 is fixedly connected to a first driven gear 56. The first driven gear 56 is meshed with a first driving gear 57. The first driving gear 57 is connected to a first motor 58 via a motor shaft. Multiple equally spaced air intakes 59 are installed on the rotary pipe 55. Multiple evenly distributed cleaning brushes 510 are fixedly connected to the outside of the rotary pipe 55. This moves the chuck 45 and the pad 46 to the position of the cleaning component 5. The cleaning brushes 510 and the negative pressure adsorption structure clean the debris on the chuck 45 and the pad 46, avoiding increased friction between the chuck 45 and the aluminum profile surface, and also avoiding uneven clamping force between the chuck 45 and the aluminum profile, which could cause the aluminum profile to slip or deviate during traction.

[0032] Specifically, the lifting and rotating assembly 2 includes a cylinder 21 mounted on the conveyor frame 1. The piston rod of the cylinder 21 is connected to a fixed lug 22. The fixed lug 22 is fixedly connected to a lifting frame 23. The lifting frame 23 is rotatably connected to a second driven gear 24. The second driven gear 24 is meshed with a second driving gear 25. The second driving gear 25 is connected to a second motor 26 via a motor shaft. The second driving gear 25 is fixedly connected to a mounting bracket 3, which can drive the clamping assembly 4 to lift and rotate at a certain angle. This allows for more accurate clamping of aluminum profiles, and makes it less likely for the aluminum profiles to displace when they are released, thus facilitating the traction of the aluminum profiles.

[0033] Furthermore, a first fixed frame 6 is fixed on the conveyor frame 1, the cylinder 21 is installed on the first fixed frame 6, a second fixed frame 7 is fixed on the lifting frame 23, and a second motor 26 is located on the second fixed frame 7, which can fix the cylinder 21 and the second motor 26.

[0034] Furthermore, the clamping assembly 4 includes a third motor 41 mounted on the mounting bracket 3. The third motor 41 is connected to a third driving gear 42 via a motor shaft. The third driving gear 42 is meshed with a third driven gear 43. The third driven gear 43 is fixedly connected to a rotating rod 44. The rotating rod 44 is fixedly connected to a chuck 45. A pad 46 is provided below the chuck 45. The pad 46 is fixedly connected to the mounting bracket 3 for clamping the aluminum profile to facilitate traction.

[0035] It is worth noting that the chip collection box 52 includes a box body 521 and a filter screen 522. The filter screen 522 is located inside the box body 521 near the fan 51 to trap the chips inside the box body 521.

[0036] It is worth noting that a fixing plate 8 is fixed on the conveyor frame 1 at the position corresponding to the first motor 58. The first motor 58 is mounted on the fixing plate 8 for fixing the first motor 58.

[0037] Among them, cylinder 21, second motor 26, third motor 41, fan 51 and first motor 58 are existing technologies and will not be described in detail; at the same time, this utility model also includes power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail.

[0038] Working principle and process: After the traction machine pulls the aluminum profile to a suitable position, the third motor 41 of the clamping assembly 4 is started, which in turn drives the third driven gear 43 to rotate. This causes the rotating rod 44 to rotate the clamp 45 and disengage it from the aluminum profile. Then, the cylinder 21 of the lifting and rotating assembly 2 is started, which causes the fixed ear 22 to move the lifting frame 23 downwards, thus lowering the clamping assembly 4. This allows both the clamp 45 and the pad 46 to disengage from the aluminum profile, preventing the traction machine from pulling on the aluminum profile. The second motor 26 is then started, which in turn drives the second driven gear 24 to rotate. This causes the mounting bracket 3 to rotate the clamping assembly 4 90 degrees, allowing the clamp to move further away from the aluminum profile. It is positioned above the conveyor frame 1. At the same time, the fan 51 of the cleaning component 5 is started. The external airflow passes through the air inlet 59, the rotating pipe 55, the rotating joint 54, and the U-shaped pipe 53 in sequence and is then introduced into the chip collection box 52. The debris flowing with the air can be trapped in the chip collection box 52. The first motor 58 is started, and then the first driving gear 57 drives the first driven gear 56 to rotate, which makes the rotating pipe 55 rotate. The cleaning brush 510 cleans the chuck 45 and the pad 46, avoiding aggravating the friction between the chuck 45 and the aluminum profile surface, and also avoiding uneven clamping force between the chuck 45 and the aluminum profile, so that the aluminum profile will slip or deviate during the traction process.
