Embodiment Construction

[0017] The drawing production method of the aluminum-clad light unit: the drawing position of the drawing die is placed in an environment full of water, and the aluminum tube to be drawn is formed once through the drawing position of the drawing die in an environment surrounded by water. The aluminum-clad light unit of the corresponding diameter after drawing is required to complete the drawing and direct take-up under the action of the rear take-up traction.

[0018] The mold core at the drawing position of the drawing die is a nano-diamond composite coating mold. After the surface of the nano-diamond composite coating of the mold core is polished, the surface roughness reaches Ra≤0.1μm, which has self-lubricating properties and is close to the wetting angle of water. 0°, which makes the material very hydrophilic. The hydrophilic property of the working surface makes the water form a continuous lubricating film, and the self-lubricating graphite structure is evenly distributed...

Abstract

The invention provides a drawing production method for an aluminum cladding optical unit. No drawing oil residues are generated through water drawing in the drawing process, the field environment is improved, and the expenditure and cost are reduced. A drawing position of a drawing die is put into an environment filled with water. An aluminum tube to be drawn passes through the drawing position of the drawing die in the environment where water surrounds the aluminum tube to be drawn to form the aluminum cladding optical unit with the corresponding diameter at a time after drawing. Drawing and direct take-up are completed under the action of rear take-up drawing. The invention further provides a tool device adopted in the drawing production method for the aluminum cladding optical unit.

Description

technical field [0001] The invention relates to the technical field of optical unit production, in particular to a drawing production method of an aluminum-clad optical unit, and the invention also provides a tooling device for the drawing production method of an aluminum-clad optical unit. Background technique [0002] In the production of traditional aluminum clad units, in order to achieve a uniform and stable outer diameter and strength, after the aluminum tube is coated, the aluminum clad unit with the required tube diameter is obtained through several times of drawing. When drawing, aluminum drawing oil is needed to ensure the stability of the drawing process. After drawing, some drawing oil remains on the surface of the aluminum tube. When the belt is used for traction, it is easy to slip. Therefore, it is necessary to clean the drawing oil and consume a large amount of n-bromopropane, which has a great impact on the site environment and is not conducive to employees....
