Description
Technical field
The utility model relates to Electric Discharge Wire-cutting Technology field, especially a kind of upper guide frame of Linear cut.
Background technology
Wire cutting machine tool is the principle utilizing " electric discharge processing ", galvanic corrosion (spark discharge) is carried out to conductive material, reach the object of processing, usually wire is utilized, as have molybdenum filament, copper wires etc. are as tool-electrode, by tool-electrode equably around on cylindrical wire storage tube, by wire feeders such as guide wheels, formation can the movement wire system of reciprocation cycle, this electrode does reciprocation cycle motion with certain speed (about 10-12m/s), workpiece is as the orbiting motion of another electrode under control of the computer automatically set by follow procedure, electric spark high frequency pulse power supply is by certain frequency, the continuous high frequency pulse of certain energy is added between these the two poles of the earth, spark discharge processing is carried out to workpiece, finally obtain the workpiece of required shape.
In cutting process, wire electrode moves back and forth, and therefore needs wire electrode in good order to be arranged on wire storage cylinder by spiral, otherwise can cause that wire electrode is lax, sleave, folded silk.When silk cylinder carries out commutation campaign, owing to there is folded silk, fracture of wire must be caused.In order to solve this problem, need the tension force that wire electrode keeps certain, namely wire tray can not be in free state, and it is spring that the mode adopted at present mostly is, and wire tray is passive freely rotates with silk cylinder, and dress silk effect is still undesirable, easy sleave, folded silk, fracture of wire.
Summary of the invention
The technical problems to be solved in the utility model is: the wire tray overcome in prior art in upper silk process is freely rotated, wire electrode tension is caused to be not enough to sleave, the technical deficiency of folding silk, fracture of wire, guide frame on the Linear cut providing a kind of adjustable tension, makes wire electrode rotate with silk cylinder Constrained.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of upper guide frame of Linear cut, comprise frame, described frame is provided with molybdenum filament dish and silk cylinder, the right side of described molybdenum filament dish is provided with tension retaining mechanism, and described tension retaining mechanism comprises rotating shaft and fixed mount, is provided with axle sleeve outside described rotating shaft, described axle sleeve is installed with handle and swing arm, described swing arm is contacted with molybdenum filament dish by asbestos friction sheet, and described asbestos friction sheet is arranged on the top of swing arm, described asbestos friction sheet has the cambered surface matched with molybdenum filament dish.
Further, described swing arm is connected by elastic device with between frame.
Further, there is a flexible contact layer front end of described asbestos friction sheet.
Further described handle there are some projections.
Further described axle sleeve is provided with position-limit mechanism, and described position-limit mechanism comprises some latches on axle sleeve and is arranged on the limiting tooth of the control axle sleeve one-directional rotation matched with latch on fixed mount.
Further described limiting tooth is meniscate.
The beneficial effect of employing the technical solution of the utility model is: the upper guide frame of Linear cut of the present utility model, structure is simple, between asbestos friction sheet and molybdenum filament dish, flexible contact layer is installed, decreases the friction between asbestos friction sheet and molybdenum filament dish, long service life; Asbestos friction sheet, wire tray can be stoped freely to rotate, wire electrode is rotated with silk cylinder Constrained, thus the tension force that wire electrode can be made to keep certain, avoid wire electrode produces sleave, folded silk, fracture of wire phenomenon because tension force is not enough, simple to operate, axle sleeve is provided with latch and limiting tooth, when Tensity size is suitable, rotating shaft can be fixed, simple to operate, reasonable in design.

In figure, 1 is molybdenum filament dish, and 2 is asbestos friction sheet, and 3 is handle, and 4 is protruding, and 5 is fixed mount, and 6 is elastic device, and 7 is flexible contact layer, and 8 is latch, and 9 is limiting tooth
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of upper guide frame of Linear cut, comprise frame, described frame is provided with molybdenum filament dish 1 and silk cylinder, the right side of described molybdenum filament dish 1 is provided with tension retaining mechanism, described tension retaining mechanism comprises rotating shaft and fixed mount 5, outside described rotating shaft, axle sleeve is installed, described axle sleeve is installed with handle 3 and swing arm, described swing arm is contacted with molybdenum filament dish 1 by asbestos friction sheet 2, described asbestos friction sheet 2 is arranged on the top of swing arm, described asbestos friction sheet 2 has the cambered surface matched with molybdenum filament dish 1.Adopt this structure, by turning handle 3, drive axle sleeve to rotate around rotating shaft, thus drive swing arm motion, thus regulation and control asbestos friction sheet 2 and the contact of molybdenum filament dish 1 and the state of disconnection, when asbestos friction sheet 2 contacts with molybdenum filament dish 1, molybdenum filament dish 1 rotating speed reduces, and the tensile force of molybdenum filament increases; When asbestos friction sheet 2 disconnects with molybdenum filament dish 1, molybdenum filament dish 1 rotating speed increases, and the tensile force of molybdenum filament reduces.
Described swing arm is connected by elasticity assembling device 6 with between frame, adopts this structure, by elastic device 6 by the position control of asbestos friction sheet 2 in certain scope, thus can easily the tensile force of molybdenum filament to be controlled in suitable scope.
Skid when rotating to prevent handle 3, described handle 3 has some protruding 4.
As shown in Figure 2; in order to reduce impulsive force when asbestos friction sheet 2 contacts with molybdenum filament dish 1 and frictional force; protection molybdenum filament dish 1 and asbestos friction sheet 2; extend the service life of asbestos friction sheet 2; there is a flexible contact layer front end of described asbestos friction sheet 2; flexible contact layer 7 in present embodiment adopts rubber layer, and all the other flexible materials be suitable for all fall into protection domain of the present utility model.
As shown in Figure 3, described axle sleeve is provided with position-limit mechanism, described position-limit mechanism comprises some latches on axle sleeve 8 and is arranged on the limiting tooth 9 of the control axle sleeve one-directional rotation matched with latch 8 on fixed mount 5.Adopt this structure, when on molybdenum filament, tensile force is in suitable size, be stuck between adjacent two latches 8 by limiting tooth 9, when axle sleeve does clockwise movement, limiting tooth 9 and axle sleeve do move toward one another, and now latch 8 just can be blocked master by limiting tooth 9, makes axle sleeve not continue clockwise movement, thus axle sleeve is fixed, so just the position of asbestos friction sheet 2 can be fixed; When axle sleeve does counterclockwise movement, because limiting tooth 9 does the rightabout motion with axle sleeve, axle sleeve can not be hindered to rotate counterclockwise.Described limiting tooth 9 is meniscate, is designed to meniscate by limiting tooth 9, can guarantee that axle sleeve can only counterclockwise movement, good fixing effect.
The above; be only detailed description of the invention of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should define with claim is as the criterion.
