Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy bearing cover forming technology, specifically to a powder metallurgy bearing cover forming equipment. Background Technology

[0002] Powder metallurgy is a technology that manufactures metal parts by pressing and sintering metal powders. Compared to traditional casting and forging processes, powder metallurgy offers advantages such as higher precision, less waste, and lower energy consumption, making it particularly suitable for producing complex-shaped parts. Bearing caps are key components in bearing assemblies, primarily used to seal the lubricating oil or grease inside the bearing, preventing contaminants from entering the bearing.

[0003] According to the description in the patent application CN 220311759 U, "This utility model discloses a powder metallurgy forming equipment, specifically relating to the field of metallurgical forming equipment. It includes a worktable with multiple first columns at its bottom. A base plate is connected to the bottom of each first column, and feet are installed at the bottom of the base plate. Multiple second columns are symmetrically supported at the bottom of the worktable, and a top plate is supported at the top of each second column. An extrusion mechanism is installed on the top plate, and a die body is symmetrically installed at the bottom of the extrusion mechanism. A die-changing mechanism is installed on the worktable, and a lower die body is installed on the die-changing mechanism. Two shaft holes are opened on the worktable, and bearings are installed in each shaft hole. The top of the die-changing mechanism is pressed against the worktable, and the bottom of the die-changing mechanism is installed on the base plate. This utility model not only provides extrusion buffering for parts during processing but also allows for alternating replacement of the lower die body, enabling continuous processing and simultaneous processing at two stations, thus improving processing efficiency."

[0004] Regarding the above description, the applicant believes that the following problems exist: The device can alternately replace the lower mold body through the mold changing mechanism, so that the equipment can continuously process and process two stations at a time. However, the loading and unloading of the device rely on manual operation, which may cause injury to the processing personnel. At the same time, the powder can only be added to the pressed and shaped parts after they are removed, which will undoubtedly reduce the work efficiency. Utility Model Content

[0030] Furthermore, through holes are provided at corresponding positions of the fixed rod 615 and the connecting rod 613. The connecting rod 613 is rotatably connected to the surface of the fixed rod 615. There are two extrusion blocks 612, two connecting rods 613, and two return springs 614. They are symmetrically distributed on both sides of the ejector plate 611 with the center line of the bearing cover pressing mold 4 as the center line.

Example

[0033] Please see Figure 5 In conjunction with Embodiment 1, the feeding mechanism 7 includes a storage box 71, which is located on the left side of the workbench 1. A storage box 72 is located on the top of the support frame 8 on the left side of the workbench 1. A feeding pipe 73 is fixedly connected between the bottom of the storage box 71 and the top of the storage box 72. A feeding spiral blade 74 is rotatably connected inside the feeding pipe 73.

The powder conveying process is enclosed, which can effectively prevent the powder from escaping to the outside world and causing resource waste.

[0034] Furthermore, a through hole is provided at the corresponding position of the bottom of the feeding spiral blade 74 and the feeding pipe 73. The feeding spiral blade 74 passes through the through hole and is connected to the output end of the feeding motor 75 through the reduction belt. An automatic valve is provided at the discharge port of the storage box 72 and is located directly above the bearing cover pressing mold 4.

[0035] In actual operation, when this device is in use, powder is placed into the storage bin 71, the feeding motor is started, and the feeding spiral blade 74 is rotated to stably transport the powder into the storage bin 72. The rotary motor 2 is started to drive the turntable 3 and the bearing cover pressing mold 4 to rotate. When the bearing cover pressing mold 4 is directly below the storage bin 72, the automatic valve at the discharge port of the storage bin 72 is activated to pour the powder into the bearing cover pressing mold 4. Once the bearing cover pressing mold 4 is full of powder, the automatic valve is closed and the turntable 3 continues to rotate, moving the bearing cover pressing mold 4 to the bottom of the bearing cover pressing hydraulic press 5 to press the powder into shape. After molding, the bearing cover pressing mold 4 is rotated to the unloading mechanism 6, and the unloading motor 622 is started, driving the unloading threaded rod 621 to rotate, so that the suction cylinder 623 is located directly above the bearing cover pressing mold 4. The suction cylinder 623 is started, driving the electromagnetic chuck 624 to move down, the pressure rod 625 presses down the extrusion block 612, and drives the connecting rod 613 to move down. Since the fixed rod 615 is fixed in position, the ejector plate 611 moves up, ejecting the pressed bearing cover. After the electromagnetic chuck 624 picks up the bearing cover, it moves up, and the return spring 614 drives the ejector plate 611 to return to its original position. At this time, the unloading motor 622 can transport the bearing cover into the collection box 9.
