Abstract

The utility model relates to a steel wire angle adjusting device, and aims to provide a steel wire angle adjusting device which can be used for adjusting a steel wire feeding angle. The steel wire angle adjusting device comprises a fixed seat, wherein a rotary seat is hinged on the fixed seat, and is provided with a wire guide roller; and an adjustable positioning mechanism is arranged between the fixed seat and the rotary seat. The steel wire angle adjusting device has the beneficial effects that: the steel wire feeding angle can be adjusted, and the longitudinal section of the wire guide wheel is tangential to the outer circumference of a main roller, so that the problems of wire break and wire jump of a steel wire wound on the main roller due to the change of the feeding angle of the steel wire and abnormal wear of a wire guide wheel groove are solved; and the steel wire angle adjusting device is suitable for popularizing and using.

Description

The angle wire adjusting device

Technical field

The utility model relates to a kind of parts of wire-electrode cutting device, particularly relates to a kind of angle wire adjusting device that is used on the wire saw.

Background technology

Wire saw mainly is to utilize wire rod to cut off the workpiece that for example is made up of hard brittle materials such as semi-conducting material, magnetic material, potteries.Supply with steel wire to wire saw, need steel wire be seen off to the home roll of winding side from the reel of seeing side off, and steel wire coil on home roll, in order to guarantee steel wire closely, be wound on the home roll, maintenance and home roll excircle are tangent in the time of will the steel wire feeding stress equalization.The home roll surface scribbles layer of polyurethane, along with the processing number of times increases and is worn, thereby causes the diameter of home roll to reduce; If guide roller can not be followed this variation adjustment; The angle of steel wire feeding will change so, and heel and toe wear will take place the lead race, problem such as steel wire coil will break on the home roll, wire jumper; At this moment will adjust the angle of guide roller axis, and make the guide roller section keep tangent with the home roll excircle.

The utility model content

The purpose of the utility model is to provide a kind of angle wire adjusting device that can regulate steel wire feeding angle; Being worn the back diameter with the home roll top layer layer of polyurethane that exists in the solution background technology changes; Thereby cause the angle of steel wire feeding to change; Heel and toe wear will take place in the lead race, and steel wire coil will break on the home roll, the problem of wire jumper.

To achieve these goals; The technical scheme of the utility model angle wire adjusting device is: a kind of angle wire adjusting device, comprise holder, and be hinged with rotation seat on this holder; This rotation seat is provided with guide roller, is provided with adjustable detent mechanism between said holder and the rotation seat.The mentality of designing of this angle wire adjusting device is: the supply side of steel wire is set up on the guide roller, but and the rotation seat relative fixed seat of guide roller and its interlock rotates, during installation; Make the axis normal of the axis and the home roll of guide roller; In the time of debugging, after the steel wire tension, unclamp detent mechanism; The excircle of steel wire and home roll can be tangent automatically, and locking positioning mechanism gets final product then; After the layer of polyurethane on the home roll is worn; The diameter of home roll can diminish, and then adjusts according to above-mentioned adjustment method once more, and this angle wire adjusting device can be regulated steel wire feeding angle; Make the excircle of itself and home roll tangent; Also change with regard to the angle that has solved the feeding of invar silk, cause lead race generation heel and toe wear, steel wire coil will break on the home roll, the problem of wire jumper.

As preferably, said detent mechanism comprises to be located at the arcuate socket on the holder and to be located at the screwed hole on the rotation seat, and this screwed hole is corresponding with arcuate socket, and cross-under has bolt in said arcuate socket and the screwed hole.In the time of need adjusting steel wire feeding angle, unclamp bolt, debugging tights a bolt after accomplishing again, and this detent mechanism is simple and reliable.

As preferably, said guide roller comprises the guide wheel shaft that is fixed on the rotation seat and is the rotatable guide wheel in center with said guide wheel shaft that the annular sidewall of this guide wheel is provided with annular recess, and this groove is coaxial with guide wheel shaft.Steel wire is in groove, and guide roller directs into the tangential direction of home roll excircle with steel wire, and guide wheel can rotate around guide wheel shaft.

As preferably, the section of said groove is a V-arrangement.Section is that the groove of V-arrangement can make steel wire can in groove, not rock, the feeding better effects if.

As preferably, said groove has twice.Guide roller is after long-time the use, and after one groove wearing and tearing, steel wire is inserted another road groove and can be used again, practices thrift cost.

The beneficial effect of the utility model angle wire adjusting device is: this angle wire adjusting device can be regulated steel wire feeding angle; Make the excircle of lead race vertical section and home roll tangent; Also change with regard to the angle that has solved the feeding of invar silk; Cause lead race generation heel and toe wear, steel wire coil will break on the home roll, the problem of wire jumper.

The specific embodiment

Below through embodiment and combine accompanying drawing that the technical scheme of the utility model is done further to specifically describe.

Embodiment:

As depicted in figs. 1 and 2; A kind of angle wire adjusting device comprises holder 1, and these holder 1 one sides are hinged with rotation seat 3 with bearing pin 2; Have arcuate socket 7 in holder 1 side; On rotation seat 3, have two screwed holes, these two screwed holes are all corresponding with arcuate socket 7, and cross-under has bolt respectively in these two screwed holes and arcuate socket 7.This rotation seat 3 is provided with guide roller; This guide roller comprises the guide wheel shaft 4 that is fixed on the rotation seat 3 and is the rotatable guide wheel 5 in center with guide wheel shaft 4; Have twice annular recess 6 on the annular sidewall of this guide wheel 5, this groove 6 is coaxial with guide wheel shaft, and the section of this groove 6 is a V-arrangement.

During installation, make the axis normal of the axis and the home roll 8 of guide wheel 5, the supply side with steel wire 9 sets up in the groove 6 of guide wheel 5 then.In the time of debugging, behind the taut wire, unclamp the bolt between holder 1 and the rotation seat 3, the excircle of the vertical section of guided wheel slot and home roll 8 can be tangent automatically, and clamping screw can be realized the angle adjustment of steel wire 9 then, and is as shown in Figure 3; After the layer of polyurethane on the home roll 8 was worn, the diameter of home roll 8 can diminish, and then adjusted according to above-mentioned adjustment method once more.
