Description

Technical Field

[0001] This application relates to the technical field of bearing forming equipment, specifically powder metallurgy bearing forming equipment. Background Technology

[0002] Powder metallurgy bearings are a special type of bearing. They are made by pressing, sintering, shaping, and oil impregnation of metal powders and other anti-friction material powders. These bearings have a porous structure, which can be filled with lubricating oil after being impregnated in hot oil. During operation, due to the suction effect of the journal rotation and frictional heat, the metal and oil expand due to heat, squeezing the oil out of the pores, thus providing lubrication on the friction surfaces. When the bearing cools down, the oil is drawn back into the pores, so that the bearing can be used for a long time without adding lubricating oil.

[0003] Currently, in the production of powder metallurgy bearings, the feeding assembly moves horizontally to fill the mold with powder. Then, the pressing device drives the upper mold to press down and press the powder in the mold into a bearing. Subsequently, the top mold device in the mold ejects the bearing out of the mold. Finally, the feeding assembly pushes the bearing out horizontally and fills the mold with powder during the reset process.

[0004] However, during the above implementation process, when the feeding component is resetting and filling the powder, it not only fills the powder but also scrapes it. Each time the feeding component pushes out the bearing, it pushes out the powder little by little, causing it to accumulate. The accumulated powder is then gradually pushed onto the filter screen and falls into the collection box. This means that when dealing with powders of different materials, it is necessary to manually clean the powder on the worktable that has not fallen into the collection box, thus increasing the labor intensity of the workers.

[0005] Therefore, it is necessary to provide powder metallurgy bearing forming equipment to solve the above problems.

A push rod (not shown in the figure) is fixedly installed at the output end of the cylinder 31. A feeding block 34 is fixedly installed at the end of the push rod away from the cylinder 31. The feeding block 34 is L-shaped. It should be noted that the feeding block 34 is divided into two sections: the vertical part is the first section, and the horizontal part is the second section. An opening is provided at the bottom of the second section.

[0027] Meanwhile, a material box 32 is fixedly installed on the feeding block 34, and a connecting pipe 33 is provided between the material box 32 and the second section of the feeding block 34. A solenoid valve (not shown in the figure) is provided on the connecting pipe 33. A mold groove (not shown in the figure) is opened on the slide 35. A fixed mold 36 is provided inside the mold groove. In the initial state, the push rod drives the feeding block 34 to move under the drive of the cylinder 31, thereby driving the material box 32 to move. Then, through the cooperation of the connecting pipe 33 and the opening at the bottom of the second section of the feeding block 34, the fixed mold 36 is filled with powder. At the same time, the feeding block 34 scrapes the powder, and the solenoid valve can control the amount and speed of powder filling.

[0028] like Figures 2-3 As shown, the molding assembly 2 includes a mounting bracket 22 fixedly installed inside the machine body 1. A hydraulic cylinder 21 is fixedly installed on the mounting bracket 22. A pressure rod (not shown in the figure) is fixedly installed at the output end of the hydraulic cylinder 21.

Then, the feeding assembly pushes out the bearing and powder. At this time, the powder scraping assembly 4 is activated, and two sets of scraping blocks 46 push the ejected powder towards the slide grooves 47 on both sides of the slide 35 until it falls into the collection box 48. Then, the feeding assembly resets and continues to fill powder and scrape it level. This cycle continues. It should be noted that the scraping blocks 46 push out each bearing, thereby gradually pushing the foremost bearing into the inclined surface of the slide 35 and out through multiple bearings, so that the bearings can be collected by the workers.
