Description

Technical Field

[0001] The present invention relates to the technical field of aluminum flat tube processing, in particular to an extrusion device for aluminum flat tube processing. Background Art

[0002] Aluminum is a light metal, and its compounds are widely distributed in nature, ranking third after oxygen and silicon. It is the largest type of metal among metal varieties. It is not only light in weight and strong in texture, but also has good ductility, electrical conductivity, thermal conductivity, heat resistance and nuclear radiation resistance. Aluminum flat tube, also known as "parallel flow aluminum flat tube", is a thin-walled porous flat tubular material made of refined aluminum rods, through hot extrusion and surface zinc spraying for corrosion protection.

[0003] The Chinese patent application with announcement number CN218775409U proposes an extrusion device for flat tube production, including an operating table, a first slide groove is provided on the top of the operating table, and two mounting brackets are slidably connected to the inner side of the first slide groove. The upper side of the mounting bracket is respectively connected to the first extrusion die and the second extrusion die. An aluminum flat tube body is provided on one side of the first extrusion die and the second extrusion die. By rotating the connecting rod around the rotating shaft to the inner side of the limit groove and inserting the connecting rod into one side of the pressure plate, the spring is compressed by the action of the inclined surface on one side of the locking block. Under the action of the elastic force of the spring, the locking block is inserted into the inner side of the locking groove, and the installation of the first extrusion die and the second extrusion die is completed. The operation is simple and convenient. Workers do not need to tighten multiple threaded bolts when installing the mold, which reduces the time spent by workers on fixing the first extrusion die and the second extrusion die, thereby improving the work efficiency of workers.

[0004] When the above device is installed on the extrusion die, the die is fixed by locking the locking block. Although this type of fixation is convenient for loading and unloading, it is also possible that the installation may be released due to accidental touch or external collision with the unlocking component. The stability and safety are not high enough, and the replacement of the extrusion die requires manual operation, which is relatively labor-intensive. Secondly, the two dies are combined and the extrusion task is performed by relying on the threaded rod transmission method. The thread is required to withstand the force during the extrusion process, and the thread life may be shortened, affecting the use. Summary of the Invention

The trapezoidal control block 581 is arranged between the two second trapezoidal blocks 56.

After the top of the trapezoidal control block 581 is in contact with the bottom wall of the material storage frame 3, the trapezoidal control block 581 can be prevented from rotating with the threaded adjustment rod 598, thereby ensuring that the trapezoidal control block 581 moves.

[0056] During actual operation, first, the device is powered on. The extrusion die 27 can be placed directly on the inner side of the mounting seat 22 during installation. When placed, the limiting groove 28 can provide limiting support for the extrusion die 27 to ensure the stability of the extrusion die 27 after installation. The extrusion die 27 used for processing aluminum flat tubes of different models can be placed on different mounting seats 22. After placement, the mounting seat 22 can be placed between adjacent isolation strips 271 on the platform plate 293. The isolation strips 271 not only play a spacing role, but also prevent the mounting seat 22 from rocking left and right. When the mounting seat 22 on the platform plate 293 is idle, the platform plate 293 is slightly lower than the auxiliary plate 291. When the auxiliary plate 291 is slightly higher than the platform plate 293, a limit can be provided for the mounting seat 22 to prevent the mounting seat 22 from rocking back and forth due to factors such as collision.

[0057] When the extrusion die 27 needs to be replaced, the fourth electric push rod 275 pushes and pulls the base plate 292, and the base plate 292 drives the platform plate 293 to move, thereby adjusting the position of the mounting seat 22 on the top of the platform plate 293, so that the mounting seat 22 to be placed can stay in front of the placement seat 21 or in front of the placement seat 21 in the area where there is a vacant space between adjacent isolation strips 271. Then the second electric push rod 298 works and pushes the square plate 297 on the telescopic plate 295, causing the telescopic plate 295 to extend. When the second electric push rod 298 is operated, the mounting seat 22 in the placement seat 21 can be pulled out and the mounting seat 22 on the platform plate 293 can be pushed into the placement seat 21. In this way, the extrusion die 27 can be quickly replaced, which is more labor-saving than manual operation.

[0058] After the mounting seat 22 is placed inside the placement seat 21, the first electric push rod 29 works and pushes the positioning plate 24 downward. While the positioning plate 24 moves downward, it also drives the fixing plate 25 to move. When the fixing plate 25 moves to fit the extrusion die 27, the positioning plate 24 is inserted into the positioning groove 26 to limit the mounting seat 22, thereby ensuring the stable placement of the mounting seat 22 in the placement seat 21 and the stable installation of the extrusion die 27 inside the mounting seat 22.

[0059] The material rods for processing into aluminum flat tubes can be arranged and placed in the material storage frame 3 to facilitate loading during processing. When placing them, the first blocking bar 53 and the second blocking bar 54 can block the first and second material rods counted from the bottom to the top in the material storage frame 3, and in order to effectively block material rods of different sizes, the spacing between the first blocking bar 53 and the second blocking bar 54 can be adjusted. When adjusting, the strip plate 594 is directly pulled, and the strip plate 594 drives the long plate 592 to move, and the long plate 592 drives the round rod to move, and the round rod drives the second mounting plate 52 to move, and the second mounting plate 52 drives the second blocking bar 54 to move. When it moves to the appropriate position, the threaded control rod 596 is rotated, and the threaded control rod 596 drives the friction plate 595 to move until it fits the bottom wall of the material storage frame 3. There is friction between the two, and at this time the strip plate 594 can no longer move, thereby ensuring the stability of the second blocking bar 54 after adjustment, so as to meet the placement requirements of material rods of different diameters;

[0060] When unloading, the second motor 599 works and drives the threaded adjustment rod 598 to rotate. After the threaded adjustment rod 598 rotates, it drives the trapezoidal control block 581 to move. After the trapezoidal control block 581 moves, it first squeezes the inclined surface of the second trapezoidal block 56 on the inner side of the first mounting plate 51. As the trapezoidal control block 581 continues to move, the second trapezoidal block 56 drives the first mounting plate 51 to move downward. The first mounting plate 51 drives the first blocking bar 53 to move downward until it no longer blocks the material rod raw material. The lowermost material rod raw material rolls outward and enters the interior of the supporting plate 281. The central groove inside the supporting plate 281 can provide space for the material rod raw material. The material stays in the center position. When the lowest material rod falls out, the trapezoidal control block 581 stops squeezing the second trapezoidal block 56. The elastic force of the spring 59 pushes the first mounting plate 51, prompting the first blocking bar 53 to re-enter the material storage frame 3. Then, the trapezoidal control block 581 is controlled to squeeze the oblique surface of the second trapezoidal block 56 on the second mounting plate 52. Similar to the above steps, the aluminum material rod blocked by the second blocking bar 54 rolls to the position blocked by the first blocking bar 53, thereby re-blocking the two material rods at the end to facilitate the next loading work.

[0061] After the material rod enters the interior of the supporting plate 281, the first hydraulic rod 283 pushes the pushing plate 284 after operation, and the pushing plate 284 pushes the material rod in the supporting plate 281 toward the extrusion die 27, thereby performing the extrusion molding purpose. After extrusion molding, the second hydraulic rod 276 pushes the connecting plate 277, and the connecting plate 277 drives the cutting knife 278 to move, so that the extruded aluminum flat tube can be cut off from the residual part remaining in the extrusion die 27. Before extrusion processing, the height of the supporting plate 281 can also be adjusted according to the diameter of the material rod. During adjustment, the third electric push rod 289 pushes the horizontal plate 288 up and down, and the horizontal plate 288 drives the plug-in plate 286 to move, and the plug-in plate 286 drives the supporting plate 281 to move up and down. This adjustment step can make the center position of material rods of different sizes correspond to the center of the inlet end on the extrusion die 27.

[0062] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
