Electrode wire disc damper of electric spark fast wire moving linear cutting machine tool

Abstract

The invention discloses an electrode wire disc damper of an electric spark fast wire moving linear cutting machine tool. The electrode wire disc damper is mainly used for solving the problems that during manual wire loading of the electric spark fast wire moving linear cutting machine tool and in the process that an electrode wire is wound around a wire storage cylinder from a wire disc, wire scattering, wire disordering, wire breaking during bending, uneven tension, repeated wire tightening and the like are likely to happen. The electrode wire disc damper comprises a support. A clamping groove fixed to the machine tool is formed in the lower portion of one side of the support. A wire disc supporting rod is arranged on one side of the upper portion of the support. The electrode wire disc is arranged on the wire disc supporting rod in a sleeving manner. Two damping pieces are located at the position, above the wire disc supporting rod, of the support, located on the end faces of the two sides of the electrode wire disc and attached to the end faces of the two sides of the electrode wire disc. Due to the structure, it can be known that due to the action of the damping pieces, the electrode wire disc and the wire storage cylinder can be kept to rotate synchronously when winding of the electrode wire is conducted, and the electrode wire can maintain certain tension both in the whole wire winding process and after wire winding.

Description

technical field [0001] The invention relates to the field of electrode wire winding, in particular to a wire coil damper for an electrode wire coil of an electric spark fast wire cutting machine tool. Background technique [0002] The CNC EDM fast wire cutting machine tool is an original creation of the Chinese. It is widely used in domestic colleges and universities and small and medium-sized enterprises. Because the wire feeding method is reciprocating wire feeding, and the wire feeding speed is very fast, as high as 8~10m / s, It is almost impossible to automatically install the electrode wire like the slow wire cutting machine tool. In actual production, the fast wire cutting machine tool generally uses manual pure manual installation of the electrode wire. 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...

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.
