Description
Technical Field
The invention belongs to the field of wire cutting, and particularly relates to an electric feeding device for a fast-moving wire cutting machine and the fast-moving wire cutting machine.
Background
When the quick wire cutting face is used for cutting and processing parts, because a numerical control program is adopted to drive the accurate movement of a workbench, the size, the shape and the signal placement precision of the parts are ensured, the parts with complex geometric shapes can be processed, and the parts such as thin walls, narrow grooves and the like which are difficult to process by traditional equipment can be processed, therefore, the quick wire cutting machine is often used for processing iron-based parts with higher requirements on precision, and is rarely used for processing aluminum parts, and the problems that the aluminum materials have the characteristics of soft quality, light specific gravity, low melting point, low vaporization point and the like are easy to occur in the processing:
(1) The guide wheel and the conductive block are worn seriously in early stage; because aluminum has higher conductivity, soft quality and low melting point, aluminum oxide particles generated in cutting are large and have high hardness, and are easy to adhere to molybdenum wires to grind conductive blocks and guide wheels, so that early abrasion is caused
(2) The molybdenum wire cuts a thin groove on the surface of the conductive block while cutting the aluminum material, and the molybdenum wire is clamped by the thin groove during operation, so that the operation resistance is increased, and the molybdenum wire is easy to break;
(3) Alumina electric corrosion generated in cutting is adhered to the molybdenum wire, so that poor contact between the molybdenum wire and the conductive block is caused, power feeding is unstable, cutting efficiency is reduced, and a cutting surface is rough.
At present, the problems of the rapid wire cutting machine for processing aluminum materials are not solved more, basically, starting from optimizing processing parameters, reducing generation of aluminum oxide particles by reducing pulse width or pulse current, namely reducing single pulse energy, reducing possibility of short circuit and wire breakage by reducing frequency conversion or tracking speed, or improving dielectric property and cutting property of cooling liquid by timely replacing the cooling liquid and adding a filtering device, but the measures are both temporary and permanent. Meanwhile, the molybdenum wire adhered with the alumina particles can shake during operation, a fine gap is formed between the molybdenum wire and the conductive block, spark discharge is easy to generate at the gap, a thin groove is cut on the surface of the conductive block, the thin groove can clamp the molybdenum wire, the operation resistance of the molybdenum wire is increased, and the molybdenum wire can be broken; and where the spark discharge reduces the pulse energy applied between the molybdenum wire and the workpiece, reducing the cutting efficiency.
Among the problems that easily occur when the fast wire cutting machine processes aluminum materials, the early abrasion of the conductive blocks and the guide wheels is caused by the fact that alumina electric corrosion generated in cutting is adhered to the molybdenum wire to grind the alumina electric corrosion, the problems of abnormal spark discharge between the molybdenum wire and the conductive blocks, fine grooves cut on the surface of the conductive blocks and the like are also related to the fact that alumina particles are adhered to the molybdenum wire, but the problems can be solved by changing the feeding mode and the position.
