How to Solve the Chattering Problem of Wire Barrel of Medium Wire Cutting Machine Tool
The bearings and axles in the storage drum of WEDM machine tool often have some clearances because of wear and tear, and it is easy to cause wire breakage due to the jitter of WEDM machine tool. Therefore, it is necessary to replace the worn bearing axle and other parts in the machine in time. If the high frequency power supply inside is not cut off, the molybdenum wire in the medium-speed wire-cutting machine will burn out because of the high temperature in a very short time, so it is necessary to check whether the stroke switch behind the silk container is normal or not. Wait a minute.
The wire conveying mechanism in the medium-speed wire cutting machine tool is composed of guide wheel, silk storage cylinder and wire frame. When the internal precision of wire-moving mechanism of wire-cutting machine tool decreases slowly, it will lead to the axial movement and radial jump in the Silk Storage drum. Of course, the accuracy here mainly refers to the accuracy of transmission bearings.
If the radial jump occurs between the storage drums of the medium-speed wire-cutting machine tool, it will cause the tension between the inner electrode wires to decrease slowly, which will lead to loosening of the wire, and even lead to molybdenum wire being removed from the guide groove of the wire-cutting machine tool, or even pulled off. Moreover, the axial movement between the silk storage drums can also lead to uneven filament arrangement, and sometimes filament stacking and so on.
If you want to keep the rotation between the guide wheel and the storage barrel of the WEDM machine very flexible, they must pay attention to whether the molybdenum wire inside has wobbled when they move back and forth. If the molybdenum wire has wobbled, you must analyze the reasons for the situation. In addition, the limit block at the back end of the silk storage drum of the WEDM machine tool should be adjusted properly so as to avoid the silk breakage of the silk storage drum of the WEDM machine tool due to the stroke of the machine tool.
It is very easy for the molybdenum wire and the block in the wire stopper device of the medium-speed wire-cutting machine to contact with each other, which will lead to grooves and lead to the breakage of the clamp wire. Therefore, it is necessary to replace the clamp wire in time, so the accuracy of the wire-moving mechanism must be checked more when the wire-cutting machine is in use.
