Description

Technical Field

[0001] The utility model relates to the technical field of deburring engineering plastic parts, in particular to a deburring device used for engineering plastic parts. Background Art

[0002] Deburring equipment is used to remove burrs, flash, and other irregular protrusions on the surface of workpieces to improve the workpiece's precision, finish, and service life. Dry ice deburring technology can be used to remove burrs on the surface of engineering plastic parts. Dry ice particles (solid carbon dioxide, with a temperature of minus 78.5 degrees Celsius) are sprayed onto the surface of the engineering plastic part. They quickly absorb heat and sublimate into a gaseous state, generating a significant physical impact in the process. At the same time, the low temperature of the dry ice quickly brittles the burrs on the surface of the plastic part, making them easier to remove under the action of physical impact. This method is not only highly efficient, but also environmentally friendly and pollution-free. It does not cause chemical corrosion or mechanical damage to the surface of the plastic part, and can maintain the original texture and gloss of the plastic part.

[0003] When existing burr removal equipment uses dry ice to remove burrs, dry ice particles are sprayed onto the surface of plastic parts at high speed. During this process, the dry ice may splash due to the reaction force. The splashing dry ice particles may not only directly contact the operator, causing freezing damage or skin irritation to the operator, but may also splash everywhere, and the operator may need to spend extra time to clean up the splashed dry ice particles and impurities.

[0004] For example, a device for removing PTFE burrs is disclosed in announcement number CN216357513U. In this patent, when the nozzle sprays dry ice to remove burrs on the workpiece to be processed, there is no protective structure to block it. The flying dry ice particles and impurities will be scattered in the working area, increasing the difficulty and time of cleaning. In addition, the dry ice may be splashed due to reaction force or airflow disturbance during the spraying process. When these flying dry ice particles come into contact with the human body, due to their extremely low temperature (-78.5℃), they may cause frostbite or irritation to the skin. In addition, if the operator works in the low temperature environment generated by dry ice spraying for a long time, he may feel uncomfortable and even suffer from health problems such as hypothermia and joint pain.

[0005] Therefore, it is necessary to invent a burr removal device for engineering plastic parts to solve the above problems. Utility Model Content

[0017] 2. Through the setting of the collection hopper, collection box and fan, the collection hopper is set directly below the storage table inside the protective cover, so several leakage holes opened on the storage table allow the waste, debris or dry ice particles generated during the processing to fall directly into the collection hopper below. The discharge port of the collection hopper is connected to the collection box, forming an automated collection process, and the collection box is connected to the fan. The negative pressure generated by the fan can attract and accelerate the waste into the collection box. The closed collection system effectively prevents the splashing and diffusion of waste and debris, reduces the pollution of the working environment, and protects the health of the operators.

[0036] Working principle of this utility model:

[0037] Refer to the instruction manual Figure 1-4When using the present invention, first place the engineering plastic part that needs to be deburred on the storage table 6 and clamp it with the clamp 11. The clamp 11 is driven by the linear motor in the linear motor housing 10. Then, close the cover door 3. The cover door 3 and the protective cover 2 are connected by a snap fit and are equipped with a sealing ring to ensure the sealing during the processing. The closing of the cover door 3 is driven by the cylinder 4. When the cover door 3 and the protective cover 2 are closed, due to the adaptation of the support seat 7 and the slide rail of the support table 5, the storage table 6 is synchronously moved to the inside of the protective cover 2 and is under the spray gun 14.

[0038] The equipment is then started, and the Z-axis drive module 12 begins to operate, driving the sliding sleeve 13 and the spray gun 14 below to move precisely in the vertical direction. The spray gun 14 moves to the position where the engineering plastic part needs to be deburred according to the preset program or the operator's instructions. At the same time, the dry ice particles or gas in the dry ice storage tank 15 are pressurized by the booster pump 16 and transported to the spray gun 14 through the connecting pipe. The spray gun 14 sprays the high-pressure dry ice onto the surface of the engineering plastic part, utilizing the rapid freezing and sublimation properties of the dry ice to remove the burrs on the surface of the engineering plastic part.

[0039] Refer to the instruction manual Figure 5-6 When using the utility model, the removed burrs and debris fall into the collecting hopper 17 below through the leakage hole 8 on the storage table 6, and the debris in the collecting hopper 17 enters the collecting box 18 through the discharge pipe. After the fan 19 is started, the air and fine dust in the collecting box 18 are extracted through the connecting pipe, forming a negative pressure environment, which promotes the collection and discharge of debris. A filter is provided inside the collecting box 18, which is used to intercept large particles of debris and impurities during extraction. The intercepted dust particles fall into the bottom drawer inside the collecting box 18. After the processing is completed, the operator can open the pull-out drawer of the collecting box 18 to clean up the collected debris and impurities.
