Abstract

A kind of line cutting automatic tension mechanism is applied to high-speed wire linear cutting, and purpose is to alleviate or eliminates the concavo-convex stria of cut surface, and the service life of prolongation molybdenum filament.Its principle is: be made up of clamping establishment A1, extension support P2, torsion assembly A2, the torsion spring C5 that can regulate torsion is arranged on the torsion assembly A2,2 guide wheel P8-1, P8-2 being driven by torsion spring C5 apply torsion on the online cutting molybdenum filament, make line cutting molybdenum filament keep the tension force of balance, thereby reach the purpose that alleviates or eliminate the concavo-convex stria of cut surface.

Description

High-speed wire linear cutting automatic tension mechanism

Technical field

The present invention is applied to quick-wire-moving linear cutting machine, makes molybdenum filament keep tensioning and poised state in cutting, alleviates or eliminate the concavo-convex stria of cut surface of cut workpiece.

Technical background

The workpiece that high-speed wire linear cuts out often has concavo-convex stria on the cut surface, (getting rid of moving this factor of guide wheel string) most important reason is that molybdenum filament tension force is inhomogeneous, one of molybdenum filament pine, other end are tight slightly partially, or whole molybdenum filament is all loose partially.General solution is manual tight silk at present, or installs gravity drop hammer additional, perhaps repeatedly cutting.The effect instability of manual tight silk, the DeGrain of gravity drop hammer, repeatedly cutting efficiency is low, so the cut surface stria of high-speed wire linear cutting never has effective solution.

Summary of the invention

The technical problem that solves

1, make whole molybdenum filament keep uniform tension force

2, prevent that the molybdenum filament degree of tightness that progressively becomes is inhomogeneous in cutting process

3, reduce cost, reduce the retrofit of machine tools technical difficulty

Technical scheme

1, on coil holder, adds torsion assembly A2, grapple molybdenum filament with 2 guide wheel P8-1, P8-2, tightly strand is lived molybdenum filament under the effect of torsion spring C5, torsion spring has stable torsion, and can make the moment reaction to the molybdenum filament degree of tightness variation of working at high speed, the dynamics of torsion spring can be added on adjusting according to user's needs, makes molybdenum filament keep uniform tension.

2, tightly clamp coil holder with clamp assemblies A1, and then torsion assembly A2 is fixed on the coil holder, can avoid on coil holder, holing.

Beneficial effect

After in high-speed wire linear cutting, using the present invention, can make molybdenum filament keep the tension force of balance and stability, alleviate or eliminates the concavo-convex stria of cut surface, and prolongation molybdenum filament service life.
