Description

Technical Field

[0001] The utility model relates to the technical field of powder metallurgy devices, in particular to a powder metallurgy pressing device for a guide shaft component which is easy to maintain. Background Art

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder or a mixture of metal powder and non-metallic powder as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. In the production of automotive guide shaft assemblies, powder metallurgy processing is an indispensable process for the production of guide shaft assemblies.

[0003] The existing public patent: CN202222245341.8 discloses a powder metallurgy pressing device, which puts powder into the material box so that the powder flows into the installation cylinder through the discharge trough and is located between sealing plug 1 and sealing plug 2. The cylinder drives the connecting rod to move telescopically through the connecting plate, so that the connecting rod drives sealing plug 1 and sealing plug 2 to slide along the inner wall of the installation cylinder, thereby pushing the powder between sealing plug 1 and sealing plug 2 into the installation sleeve, and flowing through the installation sleeve to the pressing groove on the pressing device body for pressing. This design can replace manual powder delivery into the pressing device body, reducing manufacturing costs.

[0004] However, in this patent, the powder between sealing plug 1 and sealing plug 2 is pushed into the installation sleeve. When the powder is pushed into the installation sleeve, the powder can generally only be accumulated on one side of the installation sleeve due to gravity. In order to ensure the quality of the powder pressing guide shaft assembly and avoid uneven pressing, the powder needs to be manually leveled. Manual leveling requires manpower, which reduces the practicability of the device. Utility Model Content

The invention solves the problem in the patent that the powder between the sealing plug one and the sealing plug two is pushed into the inside of the mounting sleeve, and when the powder is pushed into the mounting sleeve, the powder can generally only be accumulated on one side of the mounting sleeve. In order to ensure the quality of the powder pressed guide shaft assembly and avoid uneven pressing, the powder needs to be manually flattened, and manual flattening requires manpower, thereby reducing the practicality of the device.

[0051] Among them, the telescopic ends of the two electric telescopic rods 6 are fixedly connected with positioning plates 7;

[0052] The upper surface of the positioning plate 7 is provided with a rotation groove extending from the lower surface thereof.

[0055] The upper surface of the positioning plate 7 is fixedly connected with a first motor 9 .

[0056] Furthermore, the rotation output shaft of the first motor 9 is fixedly connected with a worm 10;

[0057] Wherein, the worm 10 is meshingly connected with the worm wheel 8;

[0058] Among them, a hydraulic telescopic rod 4 is arranged on the mounting frame 2, and the lower end of the hydraulic telescopic rod 4 slides through the lower surface of the mounting frame 2;

[0059] The lower end of the hydraulic telescopic rod 4 is fixedly connected with a pressing block 15 , and the pressing block 15 is adapted to the mounting sleeve 3 .

[0060] Furthermore, in the initial state, the position of the mounting plate 11 does not affect the pressing of the metallurgical powder by the pressing block 15. When the pressing device is started, the pressing device pours the metallurgical powder into the mounting sleeve 3. Before the pressing block 15 presses the metallurgical powder, the first motor 9 needs to be started. The first motor 9 starts to drive the worm 10 to rotate. The rotation of the worm 10 drives the worm wheel 8 to rotate. The rotation of the worm wheel 8 synchronously drives the positioning shaft 5 to rotate. The rotation of the positioning shaft 5 drives the mounting plate 11 to rotate. The rotation of the mounting plate 11 drives the second motor 12, the rotating rod 13, the uniform rod 14, etc. to rotate around the positioning shaft 5. During the rotation of the mounting plate 11, the second motor 12, the rotating rod 13, and the uniform rod 14 are driven to be located directly above the mounting sleeve 3. At this time, the electric telescopic rod 6 is started, and the electric telescopic rod 6 starts to drive the positioning plate 7 to move up and down The worm gear 8 and the worm 10 are driven by the second motor 12, and the worm gear 13 and the worm 14 are driven by the first motor 9, thereby synchronously driving the positioning shaft 5, the worm gear 8, the worm 10, the first motor 9, etc. to move up and down synchronously, and then synchronously driving the second motor 12, the rotating rod 13, and the uniform rod 14 to move downward. The uniform rod 14 moves into the installation sleeve 3 during the downward movement. At this time, the second motor 12 is started, and the second motor 12 starts to drive the rotating rod 13 and the uniform rod 14 to rotate. The rotation of the uniform rod 14 slowly stirs the metallurgical powder in the installation sleeve 3, thereby mixing and flattening the metallurgical powder accumulated on one side of the installation sleeve 3, so that the uneven metallurgical powder can be flattened without manual flattening, thereby ensuring the effect of powder metallurgical pressing of the guide shaft assembly, thereby ensuring the processing effect of the guide shaft assembly, saving manpower, and ensuring the practicality of the powder metallurgical pressing device of the guide shaft assembly.

[0061] Furthermore, after the metallurgical powder is mixed and leveled, the electric telescopic rod 6 is started to drive the uniform rod 14 to move upward. After the uniform rod 14 moves upward out of the mounting sleeve 3, the first motor 9 is started to drive the uniform rod 14 to rotate with the positioning shaft 5 until the mounting plate 11, the uniform rod 14, etc. do not affect the pressing of the pressing block 15.

[0063] Working principle: when the device is used, in the initial state, the position of the mounting plate 11 does not affect the pressing of the metallurgical powder by the pressing block 15. When the pressing device is started, the pressing device pours the metallurgical powder into the mounting sleeve 3. Before the pressing block 15 presses the metallurgical powder, it is necessary to start the first motor 9. The first motor 9 starts to drive the worm 10 to rotate. The rotation of the worm 10 drives the worm wheel 8 to rotate. The rotation of the worm wheel 8 synchronously drives the positioning shaft 5 to rotate. The rotation of the positioning shaft 5 drives the mounting plate 11 to rotate. The rotation of the mounting plate 11 drives the second motor 12, the rotating rod 13, the uniform rod 14, etc. to rotate around the positioning shaft 5. During the rotation of the mounting plate 11, the second motor 12, the rotating rod 13, and the uniform rod 14 are driven to be located directly above the mounting sleeve 3. At this time, the electric telescopic rod 6 is started. The electric telescopic rod 6 starts to drive the positioning plate 7 It moves up and down, thereby synchronously driving the positioning shaft 5, worm gear 8, worm 10, first motor 9, etc. to move up and down synchronously, and then synchronously driving the second motor 12, rotating rod 13, and uniform rod 14 to move downward. During the downward movement of the uniform rod 14, it moves into the installation sleeve 3. At this time, the second motor 12 is started, and the second motor 12 starts to drive the rotating rod 13 and the uniform rod 14 to rotate. The rotation of the uniform rod 14 slowly stirs the metallurgical powder in the installation sleeve 3, thereby mixing and flattening the metallurgical powder accumulated on one side of the installation sleeve 3, so that the uneven metallurgical powder can be flattened without manual flattening, thereby ensuring the effect of powder metallurgical pressing of the guide shaft assembly, thereby ensuring the processing effect of the guide shaft assembly, saving manpower, and ensuring the practicality of the powder metallurgical pressing device of the guide shaft assembly.
