High-strength plasticity aluminum alloy and preparation method thereof
This invention belongs to the field of aluminum alloy materials technology, and relates to a high-strength and ductile aluminum alloy and its preparation method. The alloy comprises, by mass fraction: 2-6% Mg, 0.4-0.9% Mn, 0.2-0.6% Si, 0.05-0.15% Sn, Fe≤0.15%, Ti≤0.1%, with the balance being Al. By introducing Sn, a low-melting-point MgSiSn primary phase is formed in the as-cast stage, and transforms from a continuous network to a discontinuous granular structure during homogenization heat treatment, weakening the adverse effects of brittle intermetallic compounds at grain boundaries. Simultaneously, Sn dissolved in the aluminum matrix forms a nanoscale MgSiSn precipitate during homogenization, serving as a heterogeneous nucleation core for the Mn-containing second phase, lowering its nucleation energy barrier, and promoting high-density, fine, and uniform precipitation, thereby achieving a synergistic improvement in the alloy's strength and ductility.

An automatic centering ball-distributing oscillator structure
This utility model discloses an automatic centering ball-distributing oscillator structure, belonging to the field of bearing assembly. The automatic centering ball-distributing oscillator structure includes an upper connecting seat, with a lower connecting seat at the bottom of the upper connecting seat. The upper and lower connecting seats are interconnected by a centering structure. This utility model solves the problems of traditional oscillating ball-distributing mechanisms, where a single soft rubber body directly connects to the ball distributor for rotational oscillation, or directly connects to an object for rotational oscillation. These mechanisms are prone to breakage of the connecting rubber body, resulting in a short service life, frequent replacement of parts, low production efficiency, and increased operating costs. More critically, when using a single soft rubber body structure, the concentricity of the oscillating component is poor, preventing automatic centering. When used in bearing production equipment, the poor concentricity of the oscillating component frequently causes it to bump against the bearing edge. This utility model patent solves all these problems, resulting in significant economic benefits.

When the plate heat exchanger is working, the limitation of 6≤H1 / Dh≤7 can reduce the phenomenon of refrigerant accumulation near the inlet due to insufficient height of the distribution cylinder and limited refrigerant rebound height. It can also reduce the phenomenon of refrigerant rebound height being too small and unable to form swirling flow due to excessive height of the distribution cylinder. The limitation of 6≤H1 / Dh≤7 makes the swirling flow of refrigerant in the distribution cylinder more stable, thereby improving the distribution uniformity of the plate heat exchanger.
