Aluminum plate supplier introduces method for removing aluminum plate burrs:
The burr of the aluminum plate is inevitable, and there are many methods in the process of handling the burr. In the process of die-casting production, burrs of die-casting parts are inevitable due to factors such as pressure shock and insufficient clamping force. In recent years, with the increasing quality requirements of die-casting parts, the requirements for burrs are also more stringent, and the methods of deburring are also emerging. The deburring process is the most troublesome. The following are the advantages and disadvantages of the Mingtai Aluminum plate supplier introduces method for removing aluminum plate burrs. You can learn more about the various deburring methods and choose the right one according to your needs. Burr method.
1, manual deburring
This is the most traditional and commonly used method in the die-casting plant. It uses a boring tool (a trowel with a manual boring tool and a pneumatic boring tool), a sandpaper, a belt machine, a grinding head, etc. as auxiliary tools.
Disadvantages: Labor costs are expensive, efficiency is not very high, and complex cross holes are difficult to remove.
Applicable object: The technical requirements for workers are not very high, and it is suitable for aluminum alloy die-casting parts with small burrs and simple product structure.
2, die deburring
The burr is made by making a die with a punch.
Disadvantages: A certain die (rough die + fine die) production cost is required, and it may be necessary to make a shaping die.
Applicable object: It is suitable for aluminum alloy die-casting parts with simple parting surface, and the efficiency and deburring effect are better than manual.
3, grinding deburring
Such deburring involves vibration, sand blasting, rollerting, etc. Currently, the die casting factory uses more.
Disadvantages: There is a problem that the removal is not very clean, and it may be necessary to manually process the residual burrs or to deburr other ways.
Applicable object: Suitable for small aluminum alloy die castings with large batch size.
4, frozen deburring
The burr is quickly embrittled by cooling, and then the projectile is sprayed to remove the burr. The price of equipment is about 200,000 and 300,000;
Applicable object: Suitable for aluminum alloy die-casting parts with small wall thickness and small volume.
5, Heat explosion deburring
Also called heat to deburring, exploding to deburring. By passing some of the easy gas into a furnace of the equipment, and then through some medium and conditions, the gas is instantaneously exploded, and the energy generated by the explosion is used to dissolve and remove the burr.
Disadvantages: expensive equipment (up to millions of prices), high technical requirements, low efficiency, side effects (rust, deformation);
Applicable object: It is mainly used in some high-precision parts and components, such as precision parts such as automobile and aerospace.
6, engraving machine deburring
Equipment prices are not very expensive (tens of thousands).
Applicable object: It is suitable for the spatial structure and the required deburring position is simple and regular.
7, chemical deburring
Deburring is automatically and selectively performed on parts made of metal materials by the principle of electrochemical reaction.
Applicable object: Suitable for internal burrs that are difficult to remove, suitable for small burrs (thickness less than 7 filaments) of pump body, valve body and so on.
8, electrolytic deburring
An electrolytic processing method for removing aluminum alloy die-cast burrs by electrolysis. Electrolytic deburring is suitable for removing burrs of cross-holes or complex shapes of concealed parts in aluminum alloy die-casting parts, and the production efficiency is high, and the deburring time generally takes only a few seconds to several tens of seconds.
Disadvantages: The electrolyte has certain corrosiveness, and the vicinity of the burr of the part is also subjected to electrolysis. The surface will lose its original luster and even affect the dimensional accuracy. The aluminum alloy die-casting parts should be cleaned and rust-proofed after deburring.
Applicable objects: Suitable for deburring of gears, connecting rods, valve bodies and crankshaft oil passage orifices, as well as rounding of sharp corners.
9, high pressure water jet deburring
Using water as the medium, it uses its instantaneous impact force to remove the burrs and flashes produced after processing, and at the same time achieve the purpose of cleaning.
Disadvantages: expensive equipment
Applicable object: Mainly used for the heart part of the car and the hydraulic control system of the construction machinery.
10, ultrasonic deburring
Ultrasonic waves produce an instantaneous high pressure to remove burrs.
Applicable object: mainly for some micro burrs, generally if the burr needs to be observed with a microscope, you can try to remove it by ultrasonic method.
11, abrasive flow deburring
Conventional vibration grinding is difficult for the burrs of the hole type. A typical abrasive flow processing process (bidirectional flow) pushes the abrasive through two vertically opposed abrasive cylinders to flow back and forth between the workpiece and the passage formed by the clamp. Abrasive effects can be produced by the abrasive entering and flowing through any area that is restricted. The extrusion pressure is controlled at 7-200 bar (100-3000 psi) for different strokes and different cycle times.
Applicable object: It can handle microporous burrs of 0.35mm without secondary burrs. The fluid characteristics can handle burrs in complex locations.
12, magnetic deburring
The magnetic grinding process is performed under the action of a strong magnetic field, and the magnetic abrasive filled in the magnetic field is arranged along the direction of the magnetic lines of force, adsorbed on the magnetic pole to form an “abrasive brush”, and a certain pressure is generated on the surface of the workpiece, and the magnetic pole drives the “abrasive material”. While the brush rotates, a certain gap is maintained along the surface of the workpiece, thereby achieving finishing of the surface of the workpiece.
Features: low cost, wide processing range and easy operation
Process elements: grinding stone, magnetic field strength, workpiece speed, etc.
13, robot polishing deburring
The principle is similar to manual deburring, just turning the power into a robot. With the support of programming technology and force control technology, flexible grinding (change of pressure and speed) is realized, and the advantage of robot deburring is highlighted.
