These materials are widely used in mechanical parts manufacturing, mold manufacturing and other fields. During production, crushing equipment is needed to crush and grind the metal blocks.

[0003] However, most existing crushing devices are open when crushing metal blocks, which not only easily generates a lot of dust, but also makes it easy for impurities to be mixed into the metal powder. Obviously, this will not only damage the surrounding working environment, but also affect the purity of the metal powder. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] In existing crushing devices, most are open when crushing metal blocks, which not only easily generates a large amount of dust, but also readily introduces impurities into the resulting metal powder. This clearly damages the surrounding working environment and affects the purity of the metal powder. To address this technical deficiency in existing technologies, such as... Figures 1-4 As shown in the figure, this embodiment proposes a metal powder production raw material crushing system that can quickly complete the crushing and grinding of metal blocks in a closed space. The system has a metal crushing mechanism 2 inside the outer mounting cylinder 1 to grind the metal blocks into metal powder. An auxiliary unloading mechanism 3 is set below the outer mounting cylinder 1. After the operator puts the grinding media and metal blocks into the outer mounting cylinder 1, the metal crushing mechanism 2 will automatically grind the metal blocks into metal powder. Then, the auxiliary unloading mechanism 3 will pour out the powder.

[0023] To quickly crush and grind the metal block, this embodiment includes a metal crushing mechanism 2. Specifically, the metal crushing mechanism 2 includes an inner rotating cylinder 201 coaxially arranged with the outer mounting cylinder 1. A raised strip is fixedly installed on the inner wall of the inner rotating cylinder 201. When the inner rotating cylinder 201 rotates, the grinding medium, under the combined action of centrifugal force and the raised strip, follows the inner rotating cylinder 201 to a certain height. An annular gear ring 202 is fixedly sleeved on the outside of the inner rotating cylinder 201. A mounting box 203 is provided on the outer mounting cylinder 1. A drive gear shaft 204 is movably installed inside the mounting box 203. 4. Engages with the ring gear 202. When the drive gear shaft 204 rotates under the action of the drive motor 205, it will cause the inner rotating cylinder 201 to rotate. The drive motor 205 is fixedly installed on the outside of the mounting box 203. A rotating door 206 is movably installed at one end of the inner rotating cylinder 201. A limit protrusion 207 is provided on the rotating door 206. A limit buckle 208 matching the limit protrusion 207 is provided on the inner rotating cylinder 201. When the inner rotating cylinder 201 rotates, the grinding media and the metal block will continuously rub and collide inside the inner rotating cylinder 201, thereby realizing the crushing and processing of the metal block.

[0024] To help workers quickly complete unloading and remove incompletely crushed particles from the metal powder, this embodiment includes an auxiliary unloading mechanism 3. Specifically, the auxiliary unloading mechanism 3 includes a rotating base 301 movably mounted on the outer mounting cylinder 1. A hydraulic push rod 302 is located below the outer mounting cylinder 1, and a rubber gasket 303 is detachably mounted on the upper end of the hydraulic push rod 302. One end of the outer mounting cylinder 1 is rotatably connected to the rotating base 301. When the other end of the outer mounting cylinder 1 tilts upward, the material inside will be poured out. The rubber gasket 303 contacts the outer mounting cylinder 1. When the hydraulic push rod 302 moves upward, the end of the outer mounting cylinder 1 will tilt upward. A filter screen 304 is installed inside the receiving box 4. During the unloading process, the metal powder can be initially screened, thereby separating out the incompletely crushed metal blocks.

[0025] As can be seen from the above, when processing metal powder, the worker first puts the grinding media and metal block into the inner rotating cylinder 201, and then closes the rotating door 206. At this time, the limiting protrusion 207 will be located inside the limiting buckle 208, thereby sealing the inner rotating cylinder 201.

[0026] Next, the drive gear shaft 204 will rotate under the action of the drive motor 205. When the drive gear shaft 204 rotates, it will cause the inner rotating cylinder 201 to rotate through the cooperation with the ring gear 202. During the movement, the grinding media and metal blocks will be carried to a certain height under the action of centrifugal force, and then fall freely under the action of gravity.

[0027] During the falling process, the grinding media and the metal block will continuously collide and impact each other, thereby completing the crushing process of the metal block. In addition, the grinding media can slide and roll along the inside of the inner rotating cylinder 201, and can grind the metal block, making the metal block finer.

[0028] After crushing and grinding, the staff will open the rotating door 206. At the same time, the hydraulic push rod 302 will extend upward to lift one end of the outer mounting cylinder 1, thereby pouring out the material inside the inner rotating cylinder 201 and completing the automatic unloading.

[0029] This embodiment, by setting up a metal crushing mechanism 2, utilizes the cooperation between the inner rotating cylinder 201 and the grinding media to quickly crush and grind metal blocks in a confined space. This effectively avoids dust generation and also prevents other impurities from mixing into the metal powder, thus improving the quality of the metal powder. Furthermore, by setting up an auxiliary unloading mechanism 3, which utilizes the cooperation between the hydraulic push rod 302 and the rotating base 301, this embodiment can help workers quickly unload the material after crushing, achieving a time-saving and labor-saving effect. At the same time, it can also screen the metal powder, removing metal blocks that are not completely crushed, making it convenient to use.

[0030] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0031] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
