Deburring machine

Introduction to deburring machine equipment:

After the fan-shaped sheet is punched, each punched sheet needs to undergo strict deburring to control the burrs within a small range during the stamping process. Generally, in foreign countries, deburring is done twice in a row, and in the automatic production line for stamping, two deburring machines are connected to each other. The deburring machine can be either a roller type sanding wheel or a sand belt type deburring machine. The main characteristics of the latter are: fast rotation speed, up to 10-35m/min, easy and fast replacement of sand belts, and adaptability to various shapes and thicknesses of punching sheets. The quality of deburring with sand belt is better than that of roller grinding wheel. The sand belt is applied on a high-speed rotating rubber belt with spiral grooves, which can prevent the sand belt from being contaminated. The pressure of the sand belt is controlled by compressed air, maintaining a constant pressure, and automatically stops when the sand belt is damaged or other faults occur.

Mechanical Law

With the help of an industrial robotic arm, a rotating wire brush or grinding wheel is clamped, and the joint arm movement of the robotic arm is used to polish the areas with burrs to remove them. The robotic arm can select wire brushes or grinding wheels from the shelves of the tool library, which is suitable for removing burrs on different parts of the parts. However, this method is often not suitable for use in many situations because the arm joints of the robotic arm lack sufficient rigidity and accuracy. Moreover, due to the different structures of the parts, some parts cannot be deburred using this method and have to be equipped with other deburring equipment.

Vibration method

This is designed for deburring smaller rotating or diamond shaped parts. The parts are placed in a large container filled with granular ceramic media, the size of which varies depending on the type, size, and material of the parts with burrs. The rapid reciprocating vibration of the container causes relative motion and friction between various parts of the component and the ceramic medium, thereby removing burrs and polishing the surface of the component. The intensity of vibration can be adjusted to accommodate parts of different sizes.

Thermal energy method

The process of deburring by thermal energy method is the process of oxidizing into powder at high temperature. Thermal deburring machine seals parts with burrs in a container filled with high-pressure combustible gas and oxygen mixture. The burrs on the parts, whether on the outside, inside, or blind hole position, are surrounded by this mixed gas. When the spark plug ignites the mixed gas, it generates an instantaneous high-temperature heat wave. Because the surface area of the burr part is quite high compared to the gas, the burr burns. Within a cycle time of 15 to 30 seconds, the burr continuously oxidizes and transforms into powder, and then the workpiece is cleaned with solvent.

This method is the only one that can uniformly remove burrs. It can remove unwanted materials from the surface of all parts, even from difficult to reach internal grooves and intersecting holes, without the need for inspection afterwards. Therefore, it is widely used in deburring processes for black and non-ferrous metal parts.

Electrochemical method

Electrochemical (also known as electrolytic) deburring machine removes burrs from parts by dissolving metal materials into electrolyte through electrochemical reactions. The tool electrode is connected to the negative pole of the DC power supply, and the parts with burrs are connected to the positive pole of the power supply. A certain pressure and flow rate of electrolyte is passed through the middle, and then the DC power supply is connected. In this way, the metal as the anode gradually undergoes electrochemical dissolution, achieving the goal of removing burrs (or forming).
