The dress silk bracing frame of wire cutting machine tool
Technical field
The present invention relates to the wire electrode installing component of wire cutting machine tool, be specifically related to the dress silk bracing frame of a kind of wire cutting machine tool.
Background technology
Wire cutting machine tool has can facilitate the type post in processed complex cross section, type hole and narrow slit etc., and machining accuracy is high, and automaticity is high, easy to operate, the features such as the process-cycle is short, and cost is low and safer, so wire cutting machine tool is widely used in the precision manufactureing industries such as mould.After wire cutting machine tool fractures with conventional use wire electrode when using first, it is necessary to wire electrode is installed on wire storage cylinder.Used wire electrode is all wrapped on vinyl disc, and carries out anti-oxidation sealing at vinyl disc exterior plastic thin film.
The method installing wire electrode in reality is, first by the one ends wound of wire electrode screw place on wire storage cylinder, and tightens screw and is fixed;Injecting with a pole in the hole in the middle of the vinyl disc of wire electrode, one holds pole, the hand steered steady vinyl disc of another again;Under another people coordinates, start lathe, start to install wire electrode on wire storage cylinder.This dress silk method, owing to wire storage cylinder drives vinyl disc high speed rotating, the hand contacted with vinyl disc will produce substantial amounts of heat, be not easy to workman's manual operations;When filling silk the stability requirement of vinyl disc is higher, be not allow for bigger swing and shake, thus the installation specification of workman is higher;The vinyl disc of hand-held wire electrode carries out dress silk, and its installation quality is not high, and needs two people's compounding practices just can complete.
Chinese patent also has some utility model installed about wire electrode and patents of invention, and these technical scheme structures are excessively complicated, operation inconvenience and the shortcoming such as use cost is high, thus being difficult to promote the use of.
Summary of the invention
It is an object of the invention to, a kind of simple in construction is provided, the dress silk bracing frame of the wire cutting machine tool that easy to operate and use cost is low, it can effectively solve the vinyl disc of the hand-held wire electrode of existence in background technology and carry out the technical problems such as the operation of dress silk ribbon is inconvenient and installation quality is unstable, it is possible to the drawback existed in solution state-of-the-art technology scheme.
For reaching above-mentioned purpose, technical scheme, it includes supporting axle, supporting wheel, baffle plate, left supported plate, right supported plate and magnetic suction disc, and described support wheel is arranged on support axle by bearing, and the one end supporting wheel is provided with circular collar;Described baffle plate is also provided in supporting on axle, and near supporting the other end of wheel;Described left supported plate and the upper end of right supported plate are respectively equipped with left support hole and right support hole, the described two ends supporting axle are provided with the lower end of pad and nut, left supported plate and right supported plate and are respectively equipped with left saddle and right saddle after being each passed through left support hole and right support hole, it is provided with magnetic suction disc between described left saddle and right saddle, described magnetic suction disc be respectively provided on two sides with draw-in groove one and draw-in groove two, described left saddle and right saddle are stuck in draw-in groove one and draw-in groove two.
In technique scheme, described baffle plate be arranged over notch cuttype brake hole, be provided with circular brake bar in described brake hole, brake bar is provided with back-moving spring, and one end of brake bar is provided with block rubber, and the other end is provided with briquetting.
Described left saddle is provided with screw hole, is provided with pinching screw in described screw hole.
The beneficial effects of the present invention is: simple in construction, volume are little, light weight, cost are low, easy to operate, wire electrode installation quality is high, only needs a people can complete operation.

Detailed description of the invention
Dress silk bracing frame below in conjunction with accompanying drawing wire cutting machine tool of the present invention is described further:
From Fig. 1 and Fig. 2, the dress silk bracing frame of wire cutting machine tool of the present invention, it includes support axle 1, support wheel 2, baffle plate 3, left supported plate 5, right supported plate 5 ' and magnetic suction disc 6, and described support wheel 2 is arranged on support axle 1 by bearing, and support is taken turns one end of 2 and is provided with circular collar 21;Described baffle plate 3 is also provided in supporting on axle 1, and near supporting the other end of wheel 2;Described left supported plate 5 and the upper end of right supported plate 5 ' are respectively equipped with left support hole 52 and right support hole 52 ', the described two ends supporting axle 1 are provided with the lower end of pad and nut, left supported plate 5 and right supported plate 5 ' and are respectively equipped with left saddle 51 and right saddle 51 ' after being each passed through left support hole 52 and right support hole 52 ', be provided with magnetic suction disc 6 between described left saddle 51 and right holder 51 ', described magnetic suction disc 6 be respectively provided on two sides with draw-in groove 1 and draw-in groove 2 62.
The using method of the present invention is: is first arranged on by the vinyl disc of wire electrode on support wheel 2, opens magnetic suction disc 6, be temporarily placed at by bracing frame on the panel of wire storage cylinder side of wire cutting machine tool;One end of wire electrode is fixed on the screw of wire storage cylinder one end after godet roller, tightens screw;Again bracing frame is fixed on the operating board of lathe, and makes the briquetting 43 of brake bar 4 face toward operator;Then start the drive motor of wire storage cylinder, start to fill silk;When the length that wire electrode is installed reaches instructions for use, should pressing the stop button of machine motor on the other hand, another hands slowly presses lower lock block 43, makes wire storage cylinder and support wheel 2 synchronization stop;Finally, cut off wire electrode, take off bracing frame, the installation process of wire electrode can be completed.
In the present embodiment, in order to make the vinyl disc of wire electrode to stop in time, described baffle plate 3 be arranged over notch cuttype brake hole 31, be provided with circular brake bar 4 in described brake hole 31, brake bar 4 is provided with back-moving spring 41, one end of brake bar 4 is provided with block rubber 42, the other end is provided with briquetting 43, during operation, depresses briquetting 43 with hands, under the friction of the vinyl disc of wire electrode and block rubber 42, it will stop operating in time.Unclamping briquetting 43, brake bar 4 returns to initial position under the effect of back-moving spring 41.
In the present embodiment, described left saddle 51 ' is provided with screw hole 53 ', it is provided with pinching screw 54 ' in described screw hole 53 ', for guaranteeing bracing frame stability operationally, described left saddle 51 and right saddle 51 ' are stuck in draw-in groove 1 and draw-in groove 2 62, and make left supported plate 5 and right supported plate 5 ' be fixed on the both sides of magnetic suction disc 6 by pinching screw 54 '.
The present invention adopts magnetic suction disc suction type to be fixed on lathe, installs more convenient with the vinyl disc pulling down wire electrode, and comparatively reliable when bracing frame is fixed on lathe together with the charging tray of wire electrode.
