1, file, sandpaper, grinding head, etc.
Advantages: the technical requirements for workers are not very high, and ordinary people can operate it, which is suitable for products with small burrs and simple product structure.
Disadvantages: the labor cost is expensive, the efficiency is not very high, and some inner hole burrs cannot be removed.
Step 2: Death
Deburring is carried out by making a die with a punch.
Summary: It needs a certain manufacturing cost of stamping die (rough die+fine die), and a plastic die may be needed. It is suitable for products with simple parting surface and has better efficiency and deburring effect than manual operation.
3. endless
Summary: This deburring method includes vibration, sand blasting, rolling and so on, which is widely used in enterprises at present. There is a problem that the removal is not very clean, and it may be necessary to manually handle the residual burr or cooperate with other methods to deburr, which is suitable for small products with large quantities.
4. Engraving machine
Summary: The equipment price is less than tens of thousands, which is suitable for mechanical parts with simple spatial structure, and the position of deburring needs to be simple and regular.
5. refrigerator
Summary: The equipment price is between 200,000 yuan and 300,000 yuan, which is suitable for products with small burr wall thickness and small products. Burrs become brittle rapidly by cooling, and then are removed by shot peening.
6, thermal explosion machine
Summary: The equipment cost is one million yuan, the operation technology is demanding, the efficiency is low, and the side effects (rust, deformation); It is mainly used in some fields of high-precision parts, such as automotive aerospace and other precision parts.
Deburring method
1, chemical deburring
Based on the principle of electrochemical reaction, the parts made of metal materials are automatically and selectively deburred.
Comments: It is suitable for internal burrs that are difficult to remove, and for small burrs (less than 7 wires in thickness) of pump body, valve body and other products.
2, electrolytic deburring
An electrolytic machining method for removing burrs from metal parts by electrolysis.
Comments: Electrolyte is corrosive to some extent, and the parts near burrs are also electrolyzed, so the surface will lose its original luster and even affect the dimensional accuracy. After deburring, the workpiece should be cleaned and rustproof. Electrolytic deburring is suitable for deburring hidden parts or parts with complex shapes, with high production efficiency, and the deburring time usually takes only a few seconds to dozens of seconds. Suitable for deburring and chamfering gears, connecting rods, valve bodies and crankshaft oil circuits.
3, high pressure water jet deburring
Using water as the medium, the burr and flash produced after machining are removed by its instantaneous impact force, and the purpose of cleaning is achieved at the same time.
Comments: The equipment is expensive, and it is mainly used for the hydraulic control system of automobile heart and construction machinery.
4, ultrasonic deburring
Ultrasonic waves generate instantaneous high pressure to remove burrs.
Comments: Mainly aimed at some microscopic burrs, if you need to observe burrs with a microscope, you can try to remove them by ultrasonic.
