Deburring machine
Brief introduction of deburring machine equipment:
After the fan-shaped sheet is punched, each punched sheet needs to undergo strict deburring, so that the burrs during the punching process are controlled within a small range. In foreign countries, the deburring is generally performed twice in succession. In the automatic production line of the film, two deburring machines are connected in-line. The deburring machine can be a roller type or a belt type deburring machine. The main characteristics of the latter are: fast rotation speed, up to 10~35m/min, easy and quick replacement of the abrasive belt, and can adapt to punching pieces of various shapes and thicknesses. It is said that the deburring quality of the abrasive belt is better than that of the roller grinding wheel. The abrasive belt is applied on a high-speed rotating rubber belt with spiral grooves. The grooves can prevent the abrasive belt from being contaminated. The pressure of the abrasive belt is controlled by compressed air to maintain a constant pressure, and it will automatically stop when the abrasive belt is damaged or other failures occur.
Mechanical law
With the help of an industrial manipulator, the rotating wire brush or grinding wheel is clamped, and the joint arm motion of the manipulator is used to polish the burr to remove the burr. The manipulator can select wire brushes or grinding wheels from the shelf in the tool library to meet the needs of removing burrs on different parts of the parts. However, this method is often not suitable for use in many occasions because the arm joints of the manipulator lack sufficient rigidity and precision. Moreover, due to the different structure of the parts, some parts cannot be deburred by this method, and other deburring equipment has to be equipped.
Vibration method
This is designed for the deburring of smaller rotating parts or diamond-shaped parts. The parts are placed in a large container filled with granular ceramic media. The size of the media varies according to the type, size and material of the burr part. The rapid reciprocating vibration of the container makes the parts of the parts move and rub against the ceramic medium to remove burrs and polish the surface of the parts. The strength of the vibration can be adjusted to suit parts of different sizes.
Thermal method
The process of thermal deburring is a process of oxidizing into powder at high temperature. The thermal deburring machine seals the parts with burrs in a container filled with high-pressure combustible gas and oxygen. The burrs on the parts, whether on the outside, inside, or blind holes, are surrounded by this mixed gas. After the spark plug ignites the mixed gas, it generates an instantaneous high temperature heat wave. Because the ratio of the surface area of the burr part to the gas is quite high, the burr burns, and the burr continues to oxidize and transform within a cycle time of 15 to 30 seconds. Turn into powder, and then clean the workpiece with solvent.
This method is the only method that can uniformly remove burrs. It can remove all unnecessary materials from the surface of all parts, and even remove burrs from hard-to-reach internal grooves and intersecting holes, and No need to check afterwards. Therefore, it is widely used in the deburring process of ferrous and non-ferrous metal parts.
Electrochemical method
The electrochemical (also known as electrolysis) deburring machine dissolves metal materials from the parts into the electrolyte through electrochemical reactions, thereby removing the burrs on the parts. The tool electrode is connected to the negative pole of the DC power supply, and the burr parts are connected to the positive pole of the power supply. The electrolyte is passed through at a certain pressure and flow rate, and then the DC power supply is connected. In this way, the metal as the anode will gradually undergo electrochemical dissolution to achieve removal The purpose of the burr (or molding).
