Description

Technical Field

[0001] The invention relates to the technical field of aluminum flat tube processing, and in particular to an extrusion device used 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 anti-corrosion treatment.

[0003] A 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, two mounting frames are slidably connected to the inner side of the first slide groove, a first extrusion die and a second extrusion die are respectively connected to the upper side of the mounting frames, an aluminum flat tube body is provided on one side of the first extrusion die and the second extrusion die, and a connecting rod is rotated around a rotating shaft to the inner side of a limiting groove and the connecting rod is inserted into one side of a pressure plate. At this time, the spring is compressed by the action of the inclined surface on one side of the locking block, and the locking block is inserted into the inner side of the locking groove under the action of the elastic force of the spring, so that the installation of the first extrusion die and the second extrusion die can be completed. The operation is simple and convenient, and workers do not need to tighten multiple threaded bolts when installing the molds, which reduces the time spent by workers to fix 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 fixing is convenient for loading and unloading, it is also possible that the installation is 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 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

[0056] In the actual operation process, firstly, the device is connected to the power supply. When installing, the extrusion die 27 can be directly placed on the inner side of the mounting seat 22. When placing, 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.

[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, so as to adjust the position of the mounting seat 22 on the top of the platform plate 293, so that the mounting seat 22 to be placed correspondingly stays in front of the placement seat 21 or stays 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, so that the telescopic plate 295 is extended. The telescopic plate 295 drives the electromagnetic block 296 to move to the metal block 299 on the corresponding mounting seat 22. After the electromagnetic block 296 is energized, it absorbs the metal block 299 and then continues to control the second electric push rod 298 to work. According to the above principle, at this time, 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, so as to quickly replace the extrusion die 27, which is more labor-saving than manual operation.

[0058] After the mounting seat 22 is placed in the placement seat 21, the first electric push rod 29 works and pushes the positioning plate 24 downward. The positioning plate 24 moves downward and 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 on the inner side of 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 specifically, the first blocking bar 53 and the second blocking bar 54 can block the first and second material rods 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 specifically, the strip plate 594 is directly pulled, and the strip plate 594 drives the long plate 592 to move, the long plate 592 drives the round rod to move, 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 a suitable position, the threaded control rod 596 is rotated, and the threaded control rod 596 drives the friction plate 595 to move to fit 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 match 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 on 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 does not block the material bar raw material. The lowermost material bar raw material rolls outward and enters the interior of the supporting plate 281. The central groove inside the supporting plate 281 can be used for the material bar raw material The material stays at 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 inclined 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 push plate 284 after operation, and the push plate 284 pushes the material rod in the supporting plate 281 toward the extrusion die 27 to perform 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 as to cut off the extruded aluminum flat tube from the residual part remaining in the extrusion die 27. Before the extrusion process, the height of the supporting plate 281 can also be adjusted according to the diameter of the material rod. During the adjustment, the third electric push rod 289 pushes the cross plate 288 up and down, and the cross 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 cause the center position of material rods of different sizes to 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 protection scope 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 protection scope of the present invention.
