Description

Technical Field

[0001] This invention relates to the field of aluminum profile production technology, specifically to a maintenance device and method for aluminum profile extrusion dies. Background Technology

[0002] A die is a tool used under external force to shape a blank (solid or liquid) into a part with a specific shape and size. Extrusion dies are a type of die used in the hot extrusion production of aluminum profiles. Specifically, they are used to perform various extrusion shaping of metals at high temperatures, taking advantage of the material's good plasticity. In the industrial aluminum profile extrusion production process, the die ensures the cross-sectional shape and dimensional accuracy of the aluminum profile. However, with the increasing complexity and precision of the profile's cross-sectional shape, many defects inevitably appear in the die. Therefore, the maintenance of aluminum profile extrusion dies is crucial for ensuring their normal operation. Currently, die maintenance is typically performed after a period of use, neglecting cleaning and maintenance before use. This allows dirt and grime accumulated during storage to negatively impact aluminum profile production. In view of this, we propose a maintenance device and maintenance method for aluminum profile extrusion dies to solve the above problems. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention provides a maintenance device and method for an aluminum profile extrusion die. The motor is turned on, and its rotation drives the gears to rotate synchronously, causing the rack to move downwards and the extrusion die to move synchronously until it is completely submerged in water. By controlling the motor's direction, the rack moves vertically back and forth, and the extrusion die moves synchronously. During the movement of the extrusion die, it continuously drives the water flow, causing the water to continuously impact the surface of the extrusion die, thus thoroughly cleaning the surface and preventing errors in the aluminum profile products caused by the extrusion die not being maintained before use.

An auxiliary cleaning structure is provided inside the outer shell of the maintenance barrel, and the auxiliary cleaning structure is located in the upper half of the maintenance barrel. The auxiliary cleaning structure cleans the extrusion die by moving the extrusion die to the bottom of the maintenance barrel.

[0005] The present invention also provides a technical solution, wherein the auxiliary cleaning structure includes the two sets of motors, two sets of gears, two sets of racks, a connecting rod, two sets of fixing plates and a fixing base.

The two ends of the fixing seat are respectively embedded in the interior of the two sets of fixing grooves. The two sets of fixing bolts are respectively set on the outer side of the two sets of fixing plates.

[0012] The present invention also provides a technical solution in which two sets of heating layers are symmetrically arranged inside the outer shell of the maintenance bucket, and both sets of heating layers are arranged in the upper section of the maintenance bucket.

[0013] The present invention also provides a technical solution: a maintenance device and method for an aluminum profile extrusion die, the specific steps of which are as follows: A. Fix the extrusion die; A1. Unscrew the two sets of fixing bolts from the outside of the two sets of fixing plates to release the restriction on the fixing seat; A2, lift the fixing seat, and slide both ends of the fixing seat in the fixing groove until both ends of the fixing seat contact the top of the fixing groove; A3, Place the extrusion die on the surface of the fixed base; A4, loosen the fixing seat, and the fixing seat falls onto the surface of the extrusion die under its own weight; A5, screw the two sets of fixing bolts into the interior of the two sets of fixing plates respectively.

Pour clean water into the maintenance tank through the water inlet on one side of the maintenance tank until the water level is slightly lower than the end of the limit slide. B2. Turn on the motor. The motor rotates and drives the gears to rotate synchronously, which causes the rack to move downward. Driven by the two sets of racks, the extrusion mold on the fixed base surface moves downward synchronously until the extrusion mold is completely submerged in the water. B3, by controlling the direction of the motor, drives the gear to reciprocate in both forward and reverse directions, which in turn causes the rack to move vertically back and forth, and the extrusion die moves synchronously. During the movement of the extrusion die, the extrusion die continuously drives the movement of clean water, causing the clean water to continuously impact the surface of the extrusion die, thereby cleaning the surface of the extrusion die; C, Drying the extrusion die; C1 controls the motor to rotate.

Driven by the two sets of racks, the extrusion mold on the fixed base surface moves upward synchronously until the extrusion mold moves to the upper part of the maintenance barrel. C2, the heating layer is turned on, and the heating layer emits heat, causing the moisture adhering to the surface of the extrusion mold to slowly evaporate; C3, wait for the extrusion die to cool completely; D. Remove the extrusion die; D1 controls the motor to rotate, which in turn controls the extrusion die on the surface of the fixed base to move upward synchronously until the extrusion die is removed from the top of the maintenance barrel; D2.

[0014] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. Through the cooperation between the motor, gears, rack, connecting rod, fixing plate and fixing base, the motor is turned on. The motor rotation drives the gear to rotate synchronously, thereby causing the rack to move downwards and the extrusion die to move synchronously until the extrusion die is completely submerged in water. By controlling the direction of the motor, the rack is made to move vertically back and forth, and the extrusion die moves synchronously. During the movement of the extrusion die, the extrusion die continuously drives the movement of clean water, causing the clean water to continuously impact the surface of the extrusion die, thereby thoroughly cleaning the surface of the extrusion die and avoiding the problem of errors in aluminum profile products caused by the extrusion die not being maintained before use.

Through the combination of the cleaning brushes and the water flow, the extrusion die is thoroughly cleaned, increasing its cleanliness. Heat is dissipated through the heating layer, and the water adhering to the surface of the extrusion die slowly evaporates, increasing the efficiency of water evaporation and ensuring that there is no water on the die surface, thus avoiding the impact of residual water on the production of aluminum profiles.

[0018] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0019] Example: like Figure 1 - Figure 5 As shown, this embodiment proposes a maintenance device for aluminum profile extrusion dies, including a maintenance tank 1, and a water inlet and outlet opened in the lower half of the maintenance tank 1. An auxiliary cleaning structure 2 is provided inside the outer shell of the maintenance tank 1, and the auxiliary cleaning structure 2 is located in the upper half of the maintenance tank 1. The auxiliary cleaning structure 2 cleans the extrusion die by moving the extrusion die to the bottom of the maintenance tank 1. Opening the auxiliary cleaning structure 2 causes the extrusion die to be submerged in water. Then, by controlling the auxiliary cleaning structure 2 to move back and forth vertically, the extrusion die moves back and forth in the water. During the movement of the extrusion die, the extrusion die continuously pushes the water flow, causing the water flow to continuously impact the surface of the extrusion die, thereby cleaning and maintaining the extrusion die. This avoids the problem of errors in aluminum profile products caused by the extrusion die not being cleaned and maintained before use.

[0020] The auxiliary cleaning structure 2 includes two sets of motors 21, two sets of gears 22, two sets of racks 23, a connecting rod 24, two sets of fixing plates 25, and a fixing base 26. Both sets of motors 21 are located outside the maintenance tank 1. The two sets of gears 22 are respectively located at the output ends of the two sets of motors 21. The two sets of racks 23 are respectively meshed and connected to one side of the two sets of gears 22. The connecting rod 24 is located between the two sets of racks 23. Both sets of fixing plates 25 are located on the surface of the connecting rod 24. The fixing base 26 is connected to the bottom end of the two sets of fixing plates 25. When the motors 21 are turned on, they rotate, driving the gears... The rack 23 rotates synchronously, causing it to move downwards. Driven by the two racks 23, the extrusion mold on the surface of the fixed base 26 moves downwards synchronously until it is completely submerged in water. By controlling the direction of the motor 21, the rack 23 moves vertically back and forth, and the extrusion mold moves synchronously. During the movement of the extrusion mold, it continuously drives the water to move, causing the water to continuously impact the surface of the extrusion mold, thereby thoroughly cleaning the surface of the extrusion mold and avoiding the problem of errors in aluminum profile products caused by the extrusion mold not being maintained before use.

[0021] The width of the fixed base 26 is slightly wider than the width of the two sets of fixed plates 25, and the combination of the fixed plate 25 and the fixed base 26 is located at the center of the connecting rod 24. This increases the area of ​​the fixed base 26, increasing the contact area between the extrusion mold and the fixed base 26 when the extrusion mold is placed on top of the fixed base 26. This makes the extrusion mold more stable when it is fixed, and prevents it from falling off when the extrusion mold is cleaned by water flow. When the fixed position of the extrusion mold is located in the center of the maintenance tank 1, the water flow around the extrusion mold is more evenly distributed. This ensures that the extrusion mold is thoroughly cleaned and maintained around its perimeter, while also reducing the impact difference of the water flow around the extrusion mold and preventing it from being washed off.

[0022] The inner wall of the maintenance tank 1 is provided with two sets of limiting slide grooves 3 for the movement of the connecting rod 24, and the end of the limiting slide groove 3 is lower than the water inlet; during the movement of the rack 23, the connecting rod 24 is moved synchronously in the limiting slide groove 3. The limiting slide groove 3 plays a limiting role in the movement of the connecting rod 24, while ensuring that the connecting rod 24 can move to below the water inlet, so that the extrusion mold can be completely submerged in the water.

[0023] A mold fixing structure 4 is provided between the two sets of fixing plates 25. The mold fixing structure 4 includes a fixing groove 41, a fixing seat 42, and fixing bolts 43. The fixing groove 41 is opened on the inner side of the two sets of fixing plates 25. The two ends of the fixing seat 42 are respectively embedded in the interior of the two sets of fixing grooves 41. The two sets of fixing bolts 43 are respectively located on the outer side of the two sets of fixing plates 25. The two sets of fixing bolts 43 are unscrewed from the outer side of the two sets of fixing plates 25 to release the limitation on the fixing seat 42. The fixing seat 42 is lifted and the extrusion mold is placed on the surface of the fixing base 26. The fixing seat 42 is released and falls onto the surface of the extrusion mold under its own weight. The two sets of fixing bolts 43 are screwed into the interior of the two sets of fixing plates 25. The fixing seat 42 is limited by the compression of the two sets of fixing bolts 43, thus preventing the extrusion mold from falling off when cleaning the extrusion mold.

[0024] Both ends of the fixing base 42 are set as "T" shape, and the surfaces of both ends of the fixing base 42 are respectively in contact with the inner walls of the two sets of fixing slides 41. The shapes of the two ends of the fixing base 42 and the two sets of fixing slides 41 are adapted to each other. The two sets of fixing slides 41 respectively play a limiting role on the two ends of the fixing base 42, ensuring that the fixing base 42 moves stably, and at the same time, it prevents the fixing base 42 from falling out of the inside of the fixing plate 25, thus increasing the portability of use.

[0025] Both sets of fixing bolts 43 have auxiliary rings 5 ​​rotatably connected to their ends, and one side of the auxiliary rings 5 ​​is tightly fitted with the fixing plate 25. When the fixing bolts 43 are screwed into the fixing plate 25, the auxiliary rings 5 ​​move laterally inside the fixing plate 25 under the action of the fixing bolts 43, which prevents the ends of the fixing bolts 43 from scratching the fixing seat 42 when the fixing bolts 43 are moving, and also prevents the fixing bolts 43 from exerting friction on the fixing seat 42 when they rotate, so that the operator can better control the fixing bolts 43.

[0026] The inner wall of the maintenance tank 1 is equipped with a cleaning brush 6, which is in the shape of a ring. When the direction of the motor 21 is controlled to make the extrusion mold move back and forth vertically in the water, the cleaning brush 6 on the inner wall of the maintenance tank 1 continuously scrubs the surface of the extrusion mold. At the same time, the water source around the extrusion mold continuously impacts the surface of the extrusion mold. Through the cooperation of the cleaning brush 6 and the water flow, the extrusion mold is thoroughly cleaned, increasing the cleanliness of the extrusion mold.

[0027] Two sets of heating layers 7 are symmetrically arranged inside the outer shell of the maintenance barrel 1. Both sets of heating layers 7 are located in the upper section of the maintenance barrel 1. By controlling the rotation of the motor 21, the extrusion die is moved upward until the extrusion die is in the upper section of the maintenance barrel 1. The heating layer 7 is turned on and heat is emitted. The moisture attached to the surface of the extrusion die slowly evaporates, which increases the efficiency of moisture evaporation and ensures that there is no moisture on the surface of the die, thus avoiding the impact of residual moisture on the production of aluminum profiles.

[0028] A maintenance device and method for an aluminum profile extrusion die, the specific steps of which are as follows: A. Fix the extrusion die; A1. Unscrew the two sets of fixing bolts 43 from the outside of the two sets of fixing plates 25 respectively to release the restriction on the fixing seat 42; A2, lift the fixing seat 42, and slide both ends of the fixing seat 42 in the fixing groove 41 until both ends of the fixing seat 42 contact the top of the fixing groove 41. A3, Place the extrusion die on the surface of the fixed base 26; A4, loosen the fixing seat 42, and the fixing seat 42 falls onto the surface of the extrusion mold under its own weight; A5, screw the two sets of fixing bolts 43 into the interior of the two sets of fixing plates 25 respectively. By pressing the two sets of fixing bolts 43, the fixing seat 42 is limited, thereby completing the fixing of the extrusion mold. B. Clean the extrusion mold; B1. Inject clean water into the maintenance tank 1 through the water inlet on one side of the maintenance tank 1 until the water level is slightly lower than the end of the limit slide 3. B2, turn on motor 21. Motor 21 rotates and drives gear 22 to rotate synchronously, thereby causing rack 23 to move downward. Driven by the two sets of racks 23, the extrusion mold on the surface of fixed base 26 moves downward synchronously until the extrusion mold is completely submerged in water. B3, by controlling the direction of the motor 21, the gear 22 is driven to reciprocate in both forward and reverse directions, which in turn causes the rack 23 to move vertically back and forth, and the extrusion die moves synchronously. During the movement of the extrusion die, the extrusion die continuously drives the water to move, causing the water to continuously impact the surface of the extrusion die, thereby cleaning the surface of the extrusion die. C, Drying the extrusion die; C1 controls the rotation of motor 21. The rotation of motor 21 drives gear 22 to rotate synchronously, thereby causing rack 23 to move upward. Under the drive of the two sets of racks 23, the extrusion mold on the surface of the fixed base 26 moves upward synchronously until the extrusion mold moves to the upper section of the maintenance barrel 1. C2, heating layer 7 is turned on. Heating layer 7 emits heat, and the moisture adhering to the surface of the extrusion mold slowly evaporates. C3, wait for the extrusion die to cool completely; D. Remove the extrusion die; D1 controls the motor 21 to rotate, which in turn controls the extrusion mold on the surface of the fixed base 26 to move upward synchronously until the extrusion mold is removed from the top of the maintenance barrel 1; D2, unscrew the two sets of fixing bolts 43 from the outside of the two sets of fixing plates 25 respectively to release the restriction on the fixing seat 42; D3, lift the mounting bracket 42; D4.
