Description

Technical Field

[0001] The present invention belongs to the technical field of wear-resistant material production, and particularly relates to a conveying device for wear-resistant material production. Background Art

[0002] Wear-resistant materials are a large class of new materials with special electrical, magnetic, optical, acoustic, thermal, mechanical, chemical, and biological functions. They are important basic materials in high-tech fields such as information technology, biotechnology, and energy technology, as well as in national defense construction. At the same time, they also play a very important role in transforming some traditional industries.

[0003] Wear-resistant materials mainly include the following categories: wear-resistant balls, wear-resistant steel plates, wear-resistant welding rods, wear-resistant ceramics, wear-resistant floors, wear-resistant rubbers, wear-resistant pipes, wear-resistant bearings, wear-resistant welding materials, wear-resistant castings, cast stones, polymers, composite wear-resistant materials, and other wear-resistant materials. Among them, wear-resistant balls are a new type of grinding material and play an increasingly important role in various industries such as building materials and mining.

[0004] Currently, in the prior art, the production of wear-resistant balls generally uses a hot rolling process with higher efficiency and lower cost. Specifically, the heated billets (such as pipe materials made of high-chromium cast iron, high-manganese steel, and medium-carbon alloy steel) are sent between the rollers of a ball rolling mill through an electric furnace. Through the rotation and extrusion of the rollers, the billets are rolled into a preliminary spherical shape, and finally, through quenching, tempering, dimensional finishing, and surface treatment, the production of wear-resistant balls is finally completed.

[0005] In the above production process of wear-resistant balls, the preliminary control of the accuracy of wear-resistant balls is mostly achieved through parameters such as the rotation speed of the rollers and the distance between the rollers. However, the wear-resistant balls need to be conveyed by a conveying device from the ball rolling mill to the quenching equipment. For example, in gravity conveying, an inclined chute is installed between the ball rolling mill and the quenching equipment, and the rolled wear-resistant balls roll along the chute by gravity and enter the quenching equipment; another example is in mechanical pushing, where the rolled wear-resistant balls fall on the chain plates of a chain plate conveyor and are conveyed to the feed inlet of the quenching equipment as the chain plates move.

[0006] However, in the above conveying process, since the wear-resistant balls will rub and collide with the conveying device during the falling and rolling process, it will cause damage to the wear-resistant balls, which not only affects the production accuracy of the wear-resistant balls but also increases the difficulty and operation intensity of subsequent dimensional finishing of the wear-resistant balls. In view of this, based on the damage generated during the conveying process of the wear-resistant balls, the present invention provides a conveying device for wear-resistant material production to maintain the accuracy of the wear-resistant balls during the conveying process, thereby improving the production accuracy of the wear-resistant balls and reducing the difficulty and operation intensity of subsequent dimensional finishing of the wear-resistant balls. Summary of the Invention

[0012] Preferably, as a conveying device for the production of wear-resistant materials of the present invention, a base is provided at the bottom of the feeding cylinder.

[0016] The input end of the second speed reducer is connected to the output end of the second driving member, and a driving wheel meshing with a gear ring sleeved on the outer peripheral side of the grinding cylinder is connected to the output end of the second speed reducer, so that when the second driving member operates, the driving wheel can drive the grinding cylinder to perform a circular motion through the gear ring.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] The present invention relates to a conveying device for the production of wear-resistant materials, as Figures 1 - 4 shown, including a feed cylinder 1 and a conveyor shaft 3 axially arranged in the feed cylinder 1 and performing circular motion. An axially extending spiral conveyor track 31 is provided on the circumferential side of the conveyor shaft 3. A grinding cylinder 4 performing circular motion is axially sleeved on the circumferential side of the conveyor shaft 3. During conveying, the wear-resistant balls roll along the path of the spiral conveyor track 31 and are output after being rounded in cooperation with the grinding cylinder 4.

[0031] Specifically, as Figure 3 shown, the feed cylinder 1 includes a cylindrical cylinder 11 with an opening, and a hopper 12 arranged on the circumferential side of the cylinder 11 and communicating with the cylinder 11. The wear-resistant material is rolled into spheres by a rolling ball machine and enters and falls into the cylinder 11 from the hopper 12; the conveyor shaft 3 is located in the cylinder 11 and is axially arranged along the axis of the cylinder 11. The conveyor shaft 3 is driven by a first driving assembly 2 arranged on the side of the cylinder 11 far from the opening, so that the conveyor shaft 3 rotates axially in the cylinder 11; the first driving assembly 2 includes a first driving member 21 and a first speed reducer 22. The output end of the first driving member 21 is connected to the input end of the first speed reducer 22, and the output end of the first speed reducer 22 is axially connected to one end of the conveyor shaft 3. In this embodiment, the first driving member 21 is preferably a motor, or it can also be a hydraulic motor or other functional devices that can generate and transmit circular motion; and the first speed reducer 22 is preferably a speed reducer with a planetary gear structure, or other speed reducers such as a worm and worm gear structure can also be used.

[0032] During use, after the wear-resistant material rolled into spheres falls into the cylinder 11, it will enter the spiral conveyor track 31 provided on the circumferential side of the conveyor shaft 3 through the rotation of the conveyor shaft 3, and then the axial driving force is generated by the circular motion of the spiral conveyor track 31 to axially push the wear-resistant balls along the path of the spiral conveyor track 31.

[0033] Further, as Figures 4 - 5 shown, the grinding cylinder 4 has a hollow cylinder body 41 with both ends communicating. At the open end of the material cylinder 11, that is, its discharge end is rotationally and communicatively connected to one end of the cylinder body 41 through a bearing. Therefore, after the wear-resistant balls are axially pushed out by the conveying shaft 3, they will enter the cylinder body 41. It should be noted that the inner wall of the spiral conveying track 31 is semicircular, and the size of its semicircular inner wall matches the spherical roundness size required for the production of wear-resistant balls to form a plastic grinding groove. The maximum radial distance between the cylindrical inner wall of the cylinder body 41 and the inner wall of the spiral conveying track 31 is equal to the spherical diameter size required for the production of wear-resistant balls. Based on the above-defined scheme, when the wear-resistant balls enter the cylinder body 41, under the action of the frictional force between the wear-resistant balls and the inner wall of the cylinder body 41 and the inner wall of the spiral conveying track 31, the wear-resistant balls will rotate while being axially conveyed. In addition, under the size limitation between the inner wall of the spiral conveying track 31 and the inner wall of the cylinder body 41, the wear-resistant balls will continuously rub against the inner wall of the spiral conveying track 31 and the inner wall of the cylinder body 41, so as to be ground and formed into a spherical structure with higher precision, so as to improve the production precision of the wear-resistant balls, effectively reduce the dimensional changes during transportation, and reduce the difficulty and operation intensity of subsequent dimensional finishing.

[0034] Further, in order to improve the plastic grinding effect on the wear-resistant balls during transportation and at the same time improve the service life of the cylinder body 41, a second driving component 5 for driving the rotation of the cylinder body 41 is provided at the bottom of the cylinder body 41, and a gear ring 42 cooperating with the second driving component 5 is sleeved on the outer peripheral side of the cylinder body 41, as Figure 6 shown, the second driving component 5 includes a first support frame 51, and a second driving member 52 and a second reduction gear 53 provided on the top of the first support frame 51. In this embodiment, the second driving member 52 and the second reduction gear 53 are the same as the above-mentioned first driving member 21 and the first reduction gear 22, and will not be elaborated here; the input end of the second reduction gear 53 is connected to the output end of the second driving member 52, and the output end of the second reduction gear 53 is connected with a driving wheel 54 meshing with the gear ring 42 sleeved on the outer peripheral side of the grinding cylinder 4, so that when the second driving member 52 operates, the driving wheel 54 can drive the cylinder body 41 to make a circular motion through the gear ring 42.

[0035] Further, in order to improve the rotational stability of the grinding cylinder 4, a rotating support component 6 for supporting the circular motion of the cylinder body 41 is provided at both ends of the bottom of the cylinder body 41, as Figure 7 shown, it includes a second support frame 61, and roller seats 62 oppositely arranged on the top of the second support frame 61. A roller 63 is rotatably connected to the roller seat 62, and the peripheral side of the roller 63 is attached to the peripheral side of the cylinder body 41. When the cylinder body 41 rotates, the roller 63 rotates following the cylinder body 41. In addition, during implementation, a base 7 for supporting the feed cylinder 1 is provided at the bottom of the feed cylinder 1, and the rotating support component 6 and the second driving component 5 are both installed on the base 7.

[0036] In summary, during use: Place this conveying device between the ball rolling machine and the quenching equipment, and place the hopper 12 at the outlet of the ball rolling machine so that the rolled wear-resistant balls fall into the hopper 12 and enter the barrel 11. The first driving assembly 2 drives the conveying shaft 3 to axially convey the wear-resistant balls in the barrel 11 to the inlet of the quenching equipment. During the conveying process, the wear-resistant balls will enter the inside of the grinding cylinder 4. Under the continuous extrusion and shaping of the spiral conveying track 31 provided on the circumferential sides of the grinding cylinder 4 and the conveying shaft 3, the wear-resistant balls are gradually ground and shaped with high precision and then sent into the quenching equipment.

[0037] Finally, it should be noted that: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
