Problems solved by technology

Although this patent reduces the surface roughness and also plays a role in making the surface smoother, the problem in this patent is that the static fumigation will dissolve the protrusions and depressions on the surface of the workpiece to be treated at the same rate , while reducing the surface roughness, it also reduces the quality of the workpiece to be treated, thus affecting the surface treatment effect of the workpiece to be treated

Embodiment 1

[0049] First mix 18L of N-N dimethylformamide solvent and 30L of alumina balls, the average particle size of the alumina balls is 3mm, make sandy abrasives, and then place them in the treatment kettle;

[0050] Then put the workpiece to be treated (the material is nylon 6) into the workpiece basket in the processing kettle, and when the temperature of the sandy abrasive is heated to 60°C, stop heating;

[0051] Turn on the motor to drive the workpiece basket to move, so that the abrasive abrasive and the workpiece to be processed in the workpiece basket will move relative to each other for 30 minutes.

[0052] Take out the workpiece to be treated, clean it with ethanol, and place it in a drying oven with the temperature set at 157°C. After 40 minutes of heat preservation, take out the workpiece to complete its surface treatment.

Embodiment 2

[0054] First, 15L of toluene solvent is placed in the preheating kettle, and the solvent is preheated;

[0055] After the preheating tank preheats the solvent to a temperature of 60°C, start the delivery pump to transport the solvent from the preheating tank to the treatment tank, and continue to heat the solvent;

[0056] Then put the workpiece to be processed (its material is ABS plastic) into the workpiece basket in the processing kettle, and heat the solvent temperature to 88°C, when the temperature rises, stop;

[0057] Turn on the motor to drive the impeller to move, so that the solvent and the workpiece to be processed in the workpiece basket will move relative to each other for 10 minutes;

[0058] Transport the high-temperature solvent in the treatment tank to the preheating tank, and at the same time, transport the remaining low-temperature solvent in the pre-heating tank to the processing tank. After 2 minutes, stop sending the remaining low-temperature solvent in t...

Embodiment 3

[0060] Mix xylene and n-butanol by mass percentage 3:2, configure 20L mixed solvent and 30L white corundum abrasive to make sand abrasive, wherein the average particle diameter of white corundum abrasive is 1mm, and then place the sand abrasive in the treatment kettle;

[0061] Then put the workpiece to be processed (its material is nylon 12) into the workpiece basket in the processing kettle, and when the temperature of the sand and abrasive is heated to 47°C, stop heating;

[0062] Carry out heat preservation treatment on the abrasive grains of sand, and at the same time turn on the motor to drive the impeller to move, so that the abrasive grains of sand grains and the workpiece to be processed in the workpiece basket produce relative motion for 30 minutes. In the specific implementation, the heat preservation time of this step is 25 minutes;

[0063] Take out the workpiece to be treated, clean it with ethanol, and place it in a drying oven with the temperature set at 144°C. ...

Abstract

A surface treatment device and method for additively manufacturing plastic parts, wherein the device includes a processing kettle, a solvent, a workpiece basket, a heater, a temperature sensor, and a drive unit for driving the movement of the workpiece or solvent to be processed, and the workpiece basket It is installed in the processing tank, the workpiece basket contains the parts to be processed, the solvent is placed in the processing tank, and the heater is used to heat the solvent. When the temperature of the solvent detected by the temperature sensor reaches the preset temperature, the The driving unit makes the relative movement between the solvent and the workpiece to be treated. The surface treatment device for additive manufacturing of plastic parts in the present invention starts the drive unit when the temperature of the solvent detected by the temperature sensor reaches the preset temperature, so that the solvent and the part to be treated move relative to each other, so that it is easier to dissolve the part to be treated The protrusions on the surface of the workpiece are less dissolved, while the depressions of the workpiece to be treated are less dissolved, so as to effectively reduce the surface roughness and improve the surface quality of the workpiece.

Description

technical field [0001] The invention belongs to the field of surface treatment of parts, and in particular relates to a surface treatment device and method for additively manufacturing plastic parts. Background technique [0002] Additive manufacturing, also known as 3D printing or rapid prototyping, is a technology that uses ceramics, metals, ceramics or polymers as materials to form objects through layered manufacturing. Compared with traditional "subtractive" manufacturing, additive manufacturing Manufacture can manufacture products, parts or combined parts with arbitrary complex structure shape, near-closed complex structure inner cavity, hollow or nested structure, without being limited by traditional turning, milling, planing and grinding processes, maximizing the use of materials and production cycle Short, which has great advantages in aerospace, medical, automotive, mold and other fields. [0003] At present, the surface of additively manufactured plastic parts is ...
