Through the arrangement of an external heating coil, an internal heating coil, a fixed cylinder, and an annular cavity, the external heating coil and the internal heating coil start heating, thereby performing a double heating effect on the inner and outer sides of the metal material in the annular cavity; and the fixed cylinder protrudes upward, and its main purpose is to increase the contact area with the metal material, increase the heating area, and reduce the accumulation thickness of the metal material, which is conducive to uniform heating of the metal material. Then, through the arrangement of a rotating cylinder, the rotating cylinder is placed inside the annular cavity, and the metal material inside the annular cavity is separated inside and outside, so as to further reduce the accumulation thickness of the metal material, which is conducive to uniform heating of the metal material.

The revolution of the first stirring plate and the second stirring plate drives a plurality of first grinding plates and the second grinding plates to revolve. The plurality of first stirring plates and the second stirring plates are both in a V-shaped structure. The outer sides of the two ends of the first stirring plate are both inclined and fixed with a plurality of first grinding plates at intervals, and the outer sides of the two ends of the second stirring plate are both inclined and fixed with a plurality of second grinding plates at intervals.

Finally, through the arrangement of the first scraper and the second scraper, the rotating drum rotates to drive the first scraper and the second scraper to revolve, and the metal material attached to the lower end of the annular cavity is scraped off, which is conducive to uniform heating of the metal material in the annular cavity.

[0027] The present invention provides a pre-treatment axial-flow worm gear casting device and method for optimizing the use effect. Through the arrangement of a rotating shaft, a first sleeve, a chute, a first slider, a second sleeve, a second slider, and an arc-shaped chute, the first sleeve rotates to drive the two second sliders to rotate, and the two second sliders slide in the two arc-shaped chute respectively. The two arc-shaped chute heads and tails are connected to each other to form a wavy chute structure to cooperate with the first slider to slide vertically in the chute, so that the rotating shaft can rotate to drive the first sleeve and the rotating cylinder to rotate and move up and down. The rotation and up and down movement of the rotating cylinder drives a plurality of first stirring plates, a second stirring plate, a third stirring plate, and a fourth stirring plate to revolve and move up and down, thereby increasing the stirring range of the stirring assembly on the metal material in the annular cavity and improving the stirring effect of the stirring assembly on the metal material in the annular cavity. Then, through the arrangement of the first connecting rod, the first gear, the first rack, the second connecting rod, the second gear, and the second rack, the rotating drum moves up and down to drive the first stirring plate and the third stirring plate to move up and down, and the first stirring plate and the third stirring plate move up and down to drive the first connecting rod and the first gear to move up and down; the outer side of the first gear is engaged with one side of the first rack to match the vertical direction of the first rack, so that the first connecting rod rotates to drive the first stirring plate and the third stirring plate to rotate.

[0057] S1: Mold preparation: prepare the corresponding mold according to the design drawing of the axial-flow worm gear; the mold must be accurate to ensure that the cast axial-flow worm gear meets the design requirements;

[0058] S2: Melting metal, placing the selected metal material (such as copper, aluminum, zinc, etc.) into the smelting equipment and heating it to a molten state; during the smelting process, it is necessary to pay attention to controlling the temperature and composition of the metal to ensure the quality of the molten metal;

[0059] S3: Pouring, pouring the molten metal from the pouring ladle into the mold; during pouring, a stable pouring speed and pouring pressure should be maintained to ensure that the molten metal can evenly fill the mold cavity;

[0060] S4: Cooling: After the molten metal is cooled and solidified in the mold, the worm gear is taken out;

[0061] S5: Post-processing, which is the subsequent processing of the cast worm gear, including removing burrs, trimming dimensions, and performing heat treatment.

[0062] Specific use of the present invention:

[0063] First, the staff puts the selected metal material (such as copper, aluminum, zinc, etc.) into the smelting furnace 10, and then installs and fixes the cover plate 11 on the upper end of the smelting furnace 10. The staff controls the outer heating coil 21 and the inner heating coil 22 through the control box 18 to start, thereby performing a double heating effect on the inner and outer sides of the metal material in the annular cavity 49. The fixing cylinder 20 protrudes upward, and its main purpose is to increase the contact area with the metal material, increase the heating area, and reduce the accumulation thickness of the metal material, which is conducive to uniform heating of the metal material.

[0064] Secondly, the staff controls the stirring assembly to start through the control box 18, the stepper motor 12 starts to drive the rotating shaft 13 to rotate, and the first slider 27 slides vertically in the slide groove 26, the rotating shaft 13 rotates to drive the first sleeve 25 and the rotating cylinder 23 to rotate, and the rotating cylinder 23 rotates to drive the first stirring plates 31, the second stirring plates 32, the third stirring plates 36, and the fourth stirring plates 37 to revolve. Thus, the metal material located outside the rotating cylinder 23 is stirred by the revolution of the first stirring plates 31 and the second stirring plates 32; and the metal material located inside the rotating cylinder 23 is stirred by the revolution of the third stirring plates 36 and the fourth stirring plates 37, so as to stir and heat the metal material in the annular cavity 49, and improve the effect of uniform heating of the metal material in the annular cavity 49. At the same time, the rotation of the rotating cylinder 23 drives the revolution of the first scrapers 47 and the second scrapers 48 to scrape off the metal material attached to the lower end of the annular cavity 49, which is conducive to uniform heating of the metal material in the annular cavity 49. Among them, the first stirring plates 31 and the second stirring plates 32 are both V-shaped structures, and the first grinding plates 33 are fixed at an angle and interval on the outer sides of the two ends of the first stirring plates 31, and the second grinding plates 34 are fixed at an angle and interval on the outer sides of the two ends of the second stirring plates 32, so that the metal material located outside the rotating cylinder 23 can be guided and moved, and a large amount of metal material is prevented from accumulating in the lower part of the annular cavity 49, which is conducive to improving the effect of uniformly heating the metal material located outside the rotating cylinder 23. At the same time, the third stirring plates 36 and the fourth stirring plates 37 are both V-shaped structures, and the third grinding plates 38 are fixed at an angle and interval on the outer sides of the two ends of the third stirring plates 36, and the fourth grinding plates 39 are fixed at an angle and interval on the outer sides of the two ends of the fourth stirring plates 37, so that the metal material located inside the rotating cylinder 23 can be guided and moved, and a large amount of metal material is prevented from accumulating in the lower part of the annular cavity 49, which is conducive to improving the effect of uniformly heating the metal material located inside the rotating cylinder 23.

[0065] Then, the first sleeve 25 rotates to drive the two second sliders 29 to rotate, and the two second sliders 29 slide in the two arc-shaped slide grooves 30 respectively. The two arc-shaped slide grooves 30 are connected to each other at the head and tail to form a wavy slide groove structure to cooperate with the first slider 27 to slide vertically in the slide groove 26, so that the rotating shaft 13 can rotate to drive the first sleeve 25 and the rotating cylinder 23 to rotate and move up and down. The rotation and up and down movement of the rotating cylinder 23 drive a number of first stirring plates 31, second stirring plates 32, third stirring plates 36, and fourth stirring plates 37 to revolve and move up and down, increase the stirring range of the stirring assembly on the metal material in the annular cavity 49, and improve the stirring effect of the stirring assembly on the metal material in the annular cavity 49.

By having the first stirring plates 31 , the second stirring plates 32 , the third stirring plates 36 , and the fourth stirring plates 37 revolve, move up and down, and rotate, the stirring range of the stirring component on the metal material in the annular cavity 49 is further increased, and the stirring effect of the stirring component on the metal material in the annular cavity 49 is further improved, which is beneficial to uniformly heating the metal material in the annular cavity 49 .

[0067] At the same time, the first stirring plate 31 rotates to drive the first grinding plates 33 to rotate, and the second stirring plate 32 rotates to drive the second grinding plates 34 to rotate, and the first grinding plates 33 and the second grinding plates 34 are staggered, so as to grind the metal material entering between the first grinding plates 33 and the second grinding plates 34, which is beneficial to improve the efficiency of heating and melting the metal material outside the rotating cylinder 23. The third stirring plate 36 rotates to drive the third grinding plates 38 to rotate, and the fourth stirring plate 37 rotates to drive the fourth grinding plates 39 to rotate, and the third grinding plates 38 and the fourth grinding plates 39 are staggered, so as to grind the metal material entering between the third grinding plates 38 and the fourth grinding plates 39, which is beneficial to improve the efficiency of heating and melting the metal material inside the rotating cylinder 23 and reduce the generation of residues.

[0068] Finally, the metal material in the annular cavity 49 is heated to a molten state; during the smelting process, it is necessary to pay attention to controlling the temperature and composition of the metal to ensure the quality of the molten metal.

Finally, by setting the first stirring plate 31, the second stirring plate 32, the third stirring plate 36, and the fourth stirring plate 37, the first stirring plates 31 and the second stirring plates 32 revolve to stir the metal material located on the outside of the rotating cylinder 23; and the third stirring plates 36 and the fourth stirring plates 37 revolve to stir the metal material located on the inside of the rotating cylinder 23, so as to stir and heat the metal material in the annular cavity 49, thereby improving the effect of uniformly heating the metal material in the annular cavity 49.

This can guide the movement of the metal material located on the outside of the rotating cylinder 23, avoid the accumulation of a large amount of metal material in the lower part of the annular cavity 49, and help to improve the effect of uniformly heating the metal material located on the outside of the rotating cylinder 23. Then, by setting the fourth grinding plate 39 and the third grinding plate 38, the rotating drum 23 rotates to drive the third stirring plates 36 and the fourth stirring plates 37 to revolve, and the third stirring plates 36 and the fourth stirring plates 37 revolve to drive the third grinding plates 38 and the fourth grinding plates 39 to revolve.
