Description

Wire cutting wire-mounting device

Technical field

Special process Electric Discharge Wire-cutting Technology field is the utility model is related to, silk fills in more particularly to a kind of wire cutting Put.

Background technology

At present, the molybdenum filament of Wire EDM often fracture of wire, or in use for some time in use, need Regularly replace, the process for more renewing molybdenum filament is transferred to new molybdenum filament from molybdenum filament plate wheel on wire cutting curled hair cylinder and along curled hair Cylinder axis direction is evenly distributed, and the process being typically transferred to new molybdenum filament on wire cutting curled hair cylinder is referred to as upper silk, well Upper silk situation is adjacent, and quilt evenly distributed along curled hair cylinder axis direction while new molybdenum filament is wrapped on curled hair cylinder or so Tighten up, if careless slightly during upper silk just occur bad upper silk situation, such as the adjacent new molybdenum filament in left and right on curled hair cylinder There is overlapping silk in same cross-section location（I.e. folded silk）, silk of reporting to the leadship after accomplishing a task（That is sleave）, new molybdenum filament be loosely wrapped in feelings on curled hair cylinder Condition.

Silk servicing unit in existing most Wire EDM, it is that molybdenum filament plate wheel is installed on screw thread by interstitial hole On pole multi-diameter shaft, opposite side double nut it is mutual and it is next molybdenum filament plate wheel is close on screw thread pole multi-diameter shaft by stage clip, The molybdenum filament on molybdenum filament plate wheel is screwed in one end of curled hair cylinder during upper silk, starts volume wire cylinder motor, curled hair cylinder rotates simultaneously Molybdenum filament plate wheel is driven to rotate by molybdenum filament, so as to which molybdenum filament is transferred on wire cutting curled hair cylinder from molybdenum filament plate wheel, yet with Molybdenum filament plate wheel is only capable of rotating and can not being axially moveable along screw thread pole ladder shaft core, and the interstitial hole and screw thread of molybdenum filament plate wheel The fit precision of pole multi-diameter shaft is not high, and the velocity of rotation of curled hair cylinder is again very fast, therefore molybdenum filament plate wheel is frequent in rotation process The situation of bounce occurs, easily causes folded silk and sleave, causes silk to fail.In order to avoid molybdenum filament plate wheel is in the process of rotation Middle bounce, in general way is that band gloves fix molybdenum filament plate wheel to prevent its bounce with hand in upper silk, but still is existed following Weak point：

1. on during silk, because molybdenum filament plate wheel rotating speed is higher, substantial amounts of heat can be produced, if being fixed with Hand supplementary, is easily done Hinder hand, uneasy overall coefficient increases；

2. pretension is not carried out to molybdenum filament during upper silk, also without pre-tightening apparatus, it will usually molybdenum filament occur and loosely twine Situation about being wound on curled hair cylinder, it will also result in silk failure, waste molybdenum filament；

The nut on axle, Ran Houtong are generally first unclamped 3. wire tray is fixed by screw thread pole multi-diameter shaft and nut, during installation Wire tray is attached on axle by the circular hole crossed in wire tray, then tightens fixation at both ends by nut, is also needed two end nuts first during dismounting Release could pull down wire tray, and installation process trouble is complicated, efficiency is low.

Notification number is that silk electrode is connected on buckle by CN204639373U utility model patent from wire storage cylinder, shakes hand Handle cog belt when pinion rotation rotates upper silk simultaneously, although operation is more convenient, its is complicated, makes difficulty, and cost is high.
