Abstract
The invention relates to a heat treatment process, in particular to a solid solution treatment process of an aluminum alloy bar material special for a weighing sensor, and belongs to the technical field of aluminum alloy bar material treatment. The process comprises discharging, primary heat preservation, secondary heat preservation and quenching cooling. The defect that in the heat treatment process, a grain recrystallization annulus appears in a two-series aluminum alloy weighing sensor bar material can be overcome, and the tensile strength, the yield strength and the ductility of the material are greatly improved; the weighing sensor produced through the aluminum alloy bar material is attractive in appearance, stable in performance, long in service life and capable of being widely applied to the field of weighing sensors.
Description
Technical field
The present invention relates to a kind of thermal treatment process, a kind of solution heat treatment of LOAD CELLS dedicated aluminium alloy bar, belongs to rods and bars of aluminium alloy technical field of heat treatment specifically.
Background technology
Sensor is a vitals of electronic scale, and its quality directly has influence on sensitivity and the stability of electronic scale.The production technique of LOAD CELLS, very strict to the performance requriements of its material, not only require that the yield tensile ratio of material is high, hardness is suitable for processing but also must have excellent oxidation susceptibility,
anodic oxidationcan not there be aberration rear surface.In recent years, the research and production producer more options of domestic and international LOAD CELLS adopt 2 series alloys extruded barses as the processing starting material of LOAD CELLS.It is thick that 2 series alloys extruded barses are very easy to appear at the ring-type that extruded product periphery is formed
crystal grainregion-coarse grain ring.By the time of occurrence of coarse grain ring, be divided into two classes, the first kind is the coarse grain ring occurred in extrusion process, and Equations of The Second Kind is the coarse grain ring that extruded product occurs in heat treatment process.The defects such as coarse grain ring is a kind of tissue defects of extruded product, and it can cause Mechanical Properties of Products to reduce, the rear product surface aberration of oxidation.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus a kind of solution heat treatment of LOAD CELLS dedicated aluminium alloy bar is provided, can avoid 2 series alloys LOAD CELLS bars in heat treatment process, occur coarse grain ring defect, Tensile strength, yield strength, unit elongation all improve a lot.
According to technical scheme provided by the invention, a kind of solution heat treatment of LOAD CELLS dedicated aluminium alloy bar comprises the steps: 1. blowings: first bundled by several rodss and bars of aluminium alloy and hang on heat treatment furnace bin, and the rods and bars of aluminium alloy be suspended on heat treatment furnace bin being inserted in the lump power is carry out subsequent disposal in box resistance solution heat treatment furnace; 2. be once incubated: heat after completing blowing, be once incubated after being warmed to 350 ± 10 DEG C, the insulation time length is not less than 80 minutes; 3. two insulations: after completing once insulation, carry out secondary insulation after being again warmed to 470 ~ 500 DEG C, the insulation time length is not less than 20 minutes; 4. quench cooled: be transferred to rapidly in quenchant by rods and bars of aluminium alloy after secondary insulation terminates and product is cooled to less than 100 DEG C, shift out quenchant again after product cooling, the thermal treatment of rods and bars of aluminium alloy completes.
Further, the distance between adjacent two rodss and bars of aluminium alloy is greater than 50mm.
Further, quenchant adopts the water of less than 50 DEG C.
Further, transfer time was lower than 60 seconds.
Compared with the prior art the present invention has the following advantages:
The present invention can avoid 2 series alloys LOAD CELLS bars in heat treatment process, occur coarse grain ring defect, and Tensile strength, yield strength, unit elongation all improve a lot; Adopt the LOAD CELLS that this rods and bars of aluminium alloy is produced, good looking appearance, stable performance, long service life, LOAD CELLS field can be widely used in.
