Electrode Wire Disc Damper for EDM Fast Wire Cutting Machine Tool

Abstract

The invention discloses a damper for an electrode wire reel of a fast wire-cutting wire-cutting machine tool, which is mainly aimed at making the electrode wire wind from the wire reel to the wire storage cylinder during the manual wire loading process of the fast-wire-cutting wire-cutting machine tool. Problems such as loose wires, messy wires, bent and broken wires, uneven tension, and repeated tightening of wires occur. The present invention includes a bracket. Disc support rod, the electrode wire reel sleeve is placed on the wire reel support rod, and the bracket is located above the wire reel support rod. The two sides of the silk disc are bonded together. It can be seen from the structure of the present invention that through the function of the damping plate, the wire electrode reel can be kept in sync with the rotation of the wire storage cylinder when the wire electrode is being wound, and the wire electrode can be wound throughout the wire. A certain tension can be maintained during the process and after winding.

Description

technical field [0001] The invention relates to the field of electrode wire winding, in particular to an electrode wire coil damper for an electric spark fast wire cutting machine tool. Background technique [0002] CNC EDM fast wire cutting machine is a Chinese original creation and is widely used in domestic colleges and universities, small and medium-sized enterprises, because the wire feeding method is reciprocating wire feeding, and the wire feeding speed is very fast, up to 8~10m / s, It is almost impossible to automatically install the electrode wire like the slow-speed wire cutting machine. In actual production, the fast wire-cutting machine generally uses manual and purely manual installation of the electrode wire. A very important part of manual wire loading is how to wind the electrode wire from the wire reel to the wire storage drum evenly and with a certain tension. At present, this link of manual wire loading mainly has the following outstanding problems: (1) At...

Problems solved by technology

A very important link in manual wire loading is how to wind the electrode wire from the wire reel to the wire storage tube evenly and with a certain tension. At present, there are mainly the following prominent problems in this link of manual wire loading: (1) At the beginning of winding the electrode wire from the wire reel to the wire storage drum, one end of the electrode wire needs to be fixed on the end of the wire storage drum with a wire-holding screw. Make it impossible to rotate at will, otherwise, the electrode wire on the wire reel will be separated from the wire reel, and the electrode wire will be loose, messy, bent and broken.

In purely manual wire loading, generally the wire loading personnel wear gloves to apply damping force to the wire reel rotating at a constant speed, but it is difficult to ensure that the friction force received by the wire reel during constant speed rotation is uniform, causing the electrode wire to wind into the wire storage drum There is a large difference in the tension force on the surface, and short-circuit and broken wires are prone to occur during processing.

In addition, if the force applied by the hand is large, the heat generated by friction will be more, which will not only burn the rubber wire plate and easily burn the hand, but also cause the wire electrode to be easily broken if the tension force is large; if the force applied by the hand is small, the tension force of the electrode wire Insufficient, the electrode wire will vibrate during processing, easy to short circuit, or even break the wire

(3) When the winding process of the wire storage cylinder is over, when the wire storage cylinder and the wire reel stop rotating, a person who cooperates with the wire loading personnel is still required to apply force to stabilize the wire reel, otherwise the electrode wire on the wire reel will appear loose and messy.
