Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] The core of the present invention is to provide a wire tightening mechanism, which can solve the problem of affecting the machining efficiency of the machine tool due to insufficient tension force of the molybdenum wire. The wire tightening mechanism can realize continuous tensioning of the molybdenum wire, and can The wire loss of the wire can be automatically adjusted to prevent the molybdenum wire from breaking. At the same time, the wire tightening m...

Abstract

The invention discloses a wire tensioning mechanism. The wire tensioning mechanism comprises a support panel. The upper end of the support panel is provided with a wire inlet guide wheel for winding and inputting of a molybdenum wire, and a wire outlet guide wheel which is opposite to the wire inlet guide wheel at a predetermined spacing and is used for winding and outputting of the molybdenum wire. The wire tensioning mechanism further comprises a tension guide wheel which is matched with the wire inlet guide wheel and the wire outlet guide wheel and used for generating tensioning force for allowing the molybdenum wire to be tensioned and preventing the molybdenum wire from being broken, and an elastic mechanism which is connected with the side surface of the support panel in a matched mode and used for driving the tension guide wheel to stretch and retract along a side surface perpendicular to the support panel. The invention further discloses an electric discharge wire cutting machine tool provided with the wire tensioning mechanism. Through the wire tensioning mechanism, the wire tensioning effect can be obviously improved, the effect of adjusting the tension force can be achieved through reciprocating stretching and retracting movement of the tension guide wheel, meanwhile, the processing efficiency of the machine tool can be greatly improved, and the safety of workers onthe site is not affected.

Description

technical field [0001] The invention relates to the technical field of machine tool processing, in particular to a thread tightening mechanism. The invention also relates to a wire electric discharge machine tool with the wire tightening mechanism. Background technique [0002] Wire-cut electric discharge machining technology, commonly known as EDM, its principle is based on electric discharge machining technology. The so-called EDM technology is a processing technology for metal materials proposed by the former Soviet scientists Lazarenko and his wife when they discovered that the metal material inside the switch was melted and aged due to spark discharge. The principle is that the discharge electrode When the distance from the conductive material is quite close, due to the high voltage between the electrodes, it is easy to ionize the ions in the air between the electrodes, thereby forming a discharge channel and removing the conductive material. Based on this principle, ...
