Description

Technical Field

[0001] The utility model relates to the field of sealing ring production, in particular to a powder punching machine for producing sealing rings. Background Art

[0002] A sealing ring is a part used to seal fluid or gas media and is widely used in mechanical equipment to prevent fluid leakage or intrusion of external media. Powder metallurgy technology has obvious advantages in the production of sealing rings because it can produce parts with complex shapes, high material utilization and relatively low cost. Powder punching machines are used to compress metal powder into sealing rings of the required shape and size.

[0003] A powder punching machine for producing sealing rings is disclosed in the Chinese patent publication number CN116275036B. The patent has a lower die seat fixedly arranged on the machine platform, a stamping die cavity for stamping the sealing ring is provided on the lower die seat, a stamping support die cavity connected to the stamping die cavity is provided inside the lower die seat, a stamping support seat is slidably arranged in the stamping support die cavity, a lower stamping die cylinder is arranged above the stamping support seat, the lower stamping die cylinder is slidably connected to the stamping die cavity, and an inner module is arranged in the middle of the stamping die cavity; in addition, a plurality of symmetrically arranged axially parallel to the lower die seat are provided on the machine platform. A stamping positioning column, a lifting stamping plate is slidably arranged on the two stamping positioning columns, and an upper stamping die cylinder is arranged below the lifting stamping plate. The powder required for the stamping sealing ring is poured into the stamping die cavity, that is, after the powder fills the stamping die cavity between the inner module and the lower die seat, the lifting stamping plate moves downward and is pressed into the stamping die cavity through the upper stamping die cylinder below. The powder in the stamping die cavity can be stamped into a sealing ring in cooperation with the lower stamping die cylinder, and then the stamping support seat is moved upward to eject the stamped sealing ring. The stamping process is rapid and efficient. At the same time, the entire structure is simple, which solves the problem of low efficiency of manual stamping.

[0004] However, there may be a gap between the upper die and the lower die. When the upper die is inserted into the lower die, the air in the lower die recoils and blows the powder in the lower die onto the workbench through the gap. After the stamping is completed, the powder on the workbench may adhere to the bottom of the sealing ring, affecting the molding effect of the sealing ring. Utility Model Content

The sealing ring is pushed away by the push plate 403, and then the stamping mold cavity is refilled.

[0028] A cleaning mechanism is provided on the top of the workbench 1, and the cleaning mechanism includes a fixed plate 501 bolted to the support frame 203, a rotating shaft 502 is rotatably connected inside the fixed plate 501, a cleaning plate 503 is fixedly connected to the rotating shaft 502, the cleaning plate 503 abuts against the top of the workbench 1, a slide groove is provided on one side of the workbench 1, a collection box 504 is placed in the slide groove, and the collection box 504 is slidably connected in the slide groove for easy extraction.

[0029] A driving mechanism is provided above the rotating shaft 502, and the driving mechanism is used to drive the rotating shaft 502 to drive the cleaning plate 503 to rotate when the mounting plate 205 rises. The driving mechanism includes two horizontal plates 507 bolted to the front side of the support frame 203, and a rotating shaft 508 is rotatably connected between the two horizontal plates 507. A torsion spring for resetting is provided between the rotating shaft 508 and the horizontal plate 507. One end of the rotating shaft 508 extends out of the horizontal plate 507 and is fixedly connected to a driving bevel gear 512. A driven bevel gear 513 is fixedly connected to the rotating shaft 502, and the driving bevel gear 512 is meshed with the driven bevel gear 513.

[0030] The driving mechanism also includes a linkage component, which is used to drive the rotating shaft 508 to rotate when the mounting plate 205 rises. The linkage component includes a vertical plate 505 bolted to the rear side of the mounting plate 205, and a plurality of first one-way teeth 506 distributed at equal intervals are fixedly connected to the rear side of the vertical plate 505. A rotating disk 509 is fixedly connected to the rotating shaft 508, and a plurality of movable grooves are opened around the rotating disk 509. Second one-way teeth 510 are slidably connected in the movable grooves. A spring 511 is connected between the second one-way teeth 510 and the movable grooves. The first one-way teeth 506 and the second one-way teeth 511 are connected to the movable grooves. 0 are composed of straight segments and arc segments. When the mounting plate 205 drives the vertical plate 505 to drive the first one-way tooth 506 to move downward, the arc segments of the first one-way tooth 506 and the second one-way tooth 510 cooperate. At this time, the second one-way tooth 510 is squeezed by the first one-way tooth 506 and shrinks into the rotating disk 509. When the mounting plate 205 drives the vertical plate 505 to drive the first one-way tooth 506 to move upward, the straight segments of the first one-way tooth 506 and the second one-way tooth 510 cooperate. At this time, the first one-way tooth 506 drives the second one-way tooth 510 to drive the rotating disk 509 to rotate.

[0031] Working principle: When in use, first add enough powder into the material distribution box 402, and drive the material distribution box 402 to move by the electric slide rail 401. After the material distribution box 402 moves to the top of the lower mold 201, the powder inside the material distribution box 402 will fall into the stamping die cavity composed of the lower mold 201 and the inner die block 202. When the stamping die cavity is filled with powder, the material distribution box 402 is removed, and then the mounting plate 205 is controlled by the hydraulic cylinder 204 to drive the upper stamping die cylinder 206 to move downward, so as to stamp the powder in the stamping die cavity. When the upper stamping die barrel 206 is inserted into the lower die 201, the air in the lower die 201 recoils, blowing part of the powder in the lower die 201 onto the workbench 1 around the lower die 201. After the stamping is completed, the mounting plate 205 drives the upper stamping die barrel 206 to move upward by controlling the hydraulic cylinder 204. When the mounting plate 205 moves upward, it drives the vertical plate 505 to drive the first one-way tooth 506 to move upward. At this time, the first one-way tooth 506 cooperates with the straight line segment of the second one-way tooth 510, and the first one-way tooth 510 is pressed. When 506 rises, it drives the second one-way tooth 510 to drive the turntable 509 to rotate, the turntable 509 drives the rotating shaft 508 to rotate, the rotating shaft 508 drives the active bevel gear 512 to rotate, the active bevel gear 512 meshes with the driven bevel gear 513 to drive the driven bevel gear 513 to drive the rotating shaft 502 to rotate, the rotating shaft 502 drives the cleaning plate 503 to rotate, and the powder on the top of the workbench 1 is cleaned and collected to prevent the powder on the top of the workbench 1 from adhering to the bottom of the sealing ring and affecting the molding effect of the sealing ring. When the mounting plate 205 rises to the initial height, the first one-way tooth 506 loses engagement with the second one-way tooth 510, and the turntable 509 drives the rotating shaft 508 to reverse under the action of the torsion spring, prompting the cleaning plate 503 to reset, so as to facilitate the next cleaning. After cleaning, the mounting plate 302 drives the push rod 303 to move upward by controlling the electric push rod 301 to push out the sealing ring, and then the material distribution box 402 drives the push plate 403 to move, and the pushed sealing ring is pushed away by the push plate 403, and the stamping die cavity is refilled.
