Problems solved by technology

However, the existing aluminum alloy materials cannot meet the production requirements of the lock cylinder. The hardness of the material is either too high or too low. If the hardness is too high, it cannot be directly extruded during production, and if the hardness is too low, it cannot meet the processing of turning and drilling. Require

Embodiment Construction

[0007] The technical solutions of the present invention will be further specifically described below through specific examples. Provide 6 embodiments below in tabular form, and the composition of lock cylinder and parts by weight thereof are shown in the following table in each embodiment:

[0008] Proportion content of ingredients used in aluminum alloy lock cylinder (by weight parts)

[0009]

[0010] The preparation method of the lock cylinder in each embodiment is the same: heat the aluminum alloy bar made of the material used to about 380°C, and then go through the processes of die extrusion, preliminary cutting, straightening, etc., and then saw and cut to length, and frame it. Get the required aluminum alloy lock cylinder. The obtained aluminum alloy lock cylinder has better strength, hardness and better ductility, and can meet the needs of further processing and use.

Abstract

The invention discloses an aluminum alloy lock core, which comprises the following components in portion by weight: less than 0.4 portion of silicon, less than 0.4 portion of iron, 1.0 to 1.3 portions of magnesium, 1.0 to 1.2 portions of copper, 0.3 to 0.4 portion of manganese, 0.1 to 0.15 portion of chromium, 3.0 to 3.5 portions of zinc, 0.2 to 0.25 portion of titanium, and the balance being aluminum. The aluminum alloy lock core has the advantages of moderate strength and hardness of formulation materials, and good extensibility, and saves high cost for manufacturing the lock core.

Description

technical field [0001] The invention relates to the field of lock cylinders, in particular to an aluminum alloy lock cylinder. Background technique [0002] At present, most of the lock cylinders on the market are made of copper. This is because copper has the characteristics of hard material, high strength, and easy cutting and processing, which can meet the production and use requirements of lock cylinders. However, in recent years, as the price of copper has continued to rise, the cost of lock cylinders has also risen sharply. In contrast, the price of aluminum is 1 / 4 to 1 / 3 of the price of copper, and the proportion of aluminum is only 1 / 3 of that of copper. Therefore, making the lock cylinder with aluminum alloy can greatly reduce the cost. However, the existing aluminum alloy materials cannot meet the production requirements of the lock cylinder. The hardness of the material is either too high or too low. If the hardness is too high, it cannot be directly extruded dur...
