Press Head and Die Assembly
This is the core component that directly contacts the aluminum chips and withstands high pressure. During repeated extrusion, the surface of the ram is prone to wear, scratches, and even deformation, affecting the density and molding quality of the compact.
The mold cavity, due to prolonged friction with aluminum chips, gradually wears away its inner wall, resulting in reduced dimensional accuracy. Hard impurities mixed with aluminum chips can also cause mold cracks.
Bearings in the Transmission System
During equipment operation, bearings are subject to significant radial and axial loads and are subject to high-speed rotation for extended periods.
If lubrication is inadequate or the lubricant is of poor quality, the balls and raceways within the bearings can easily wear and rust, causing abnormal noise and increased vibration. In severe cases, this can lead to transmission stalling and overall operational efficiency.
Seals
Including hydraulic system seals, oil seals, and feed inlet gaskets.
In hydraulic systems, seals exposed to high-pressure oil are prone to aging, deformation, or wear, leading to oil leakage and impacting hydraulic pressure stability.
Frequent friction and collision with aluminum chips can gradually weaken the seal, potentially causing aluminum chips to scatter or dust to leak.
Cutter and Scraper Components
Some aluminum chip briquetting machines are equipped with a cutter to separate the formed briquettes, while a scraper assists in removing residual aluminum chips from the mold.
Repeated cutting can dull the cutter's blade, reducing cutting efficiency and even causing chipping. The scraper's edge can easily wear due to constant friction with the mold's inner wall, resulting in incomplete cleaning.
The accumulation of residual aluminum chips can affect subsequent briquetting.
Filter Elements
These include hydraulic oil filters and air filters. Hydraulic oil filters filter impurities from the oil.
If not replaced for an extended period, the filter element can become clogged, resulting in poor hydraulic oil circulation and impaired heat dissipation and pressure transmission.
Excessive dust absorption in the air filter can hinder heat dissipation and potentially allow dust to enter the machine, exacerbating component wear.
