Description
Technical field
The present invention relates to a kind of accurate line burnishing device; Relate in particular to a kind of Precision Machining device that is fit to the micropore wire drawing die is carried out the line polishing; The present invention relates to a kind of method of utilizing this precision line burnishing device processing micropore wire drawing die simultaneously, belongs to the precision processing technology field.
Background technology
Wire drawing is that a kind of metal that makes under external force passes through mould by force, and metal cross section is compressed, and obtains the method for metal working of desired shape of cross section and size.Wire drawing die is the instrument that the metal cross section shape and size are changed.The hole shape of wire drawing die is made up of a plurality of zones with different angles and tapering such as inlet, lubricated, compression, sizing, back taper, outlets.Wherein, the good and bad quality that directly influences product quality of the aperture of wire drawing die, hole shape precision and fineness.In order to obtain the qualified wire drawing die of hole shape, need carry out processing such as shaping and polishing to wire drawing die usually.
The line polishing processing device is one of necessaries of producing wire drawing die.The line polishing makes instrument silk and processed mould produce friction relatively with the distinctive method of operation and running orbit, the mould hole shape is formed naturally be fit to the streamlined of hot candied purposes.Therefore the wire drawing die production industry generally uses the line burnishing device that wire drawing die is carried out polishing processing, obtains the pass of high-quality with this.
The basic functional principle of wire drawing loft burnishing device is: wire drawing die is fixed on to be done the plane and rotatablely moves on the die holder; The instrument silk passes the endoporus and the wire drawing die of wire drawing die and does relative moving up and down, and on the instrument silk, carries superhard micro mists such as diamond secretly the endoporus of wire drawing die is carried out grinding, polishing.Side-play amount between the axis of instrument silk and the axis of wire drawing die has determined the size of sizing area, between the axis of the axis of wire drawing die and instrument silk the beat of certain angle can grinding, polishing compressional zone, back taper district etc.
Corresponding with it line burnishing device mainly comprises two parts: drive the jig rotating mechanism of wire drawing die mould rotation and the guide frame reciprocating mechanism that drive instrument silk moves up and down.Wire drawing die mould and instrument silk are separately fixed on jig rotating mechanism and the guide frame reciprocating mechanism, thereby realize the polishing of mould endoporus.In the prior art, the guide frame reciprocating mechanism mainly drives through electric rotating machine, adds auxiliary bodies such as eccentric wheel, crank connecting link or leading screw and makes the rotation motion reciprocating motion that is in line.Being disclosed wire drawing die automatic polishing machine in the Chinese utility model of CN201205676Y like notification number, is exactly one of them typical example.This device in, comprise frame, drive motors, transmission mechanism, straight reciprocating motion guide rod, be arranged on support, sand belt on the guide rod; Transmission mechanism comprises the eccentric wheel that is connected on the motor shaft, is hinged on the crank on the eccentric wheel eccentric shaft; One end of the other end of crank and guide rod is hinged; Guide rod is connected on the frame through the guide pin bushing of a pair of coaxial setting; Be horizontally connected with support at the guide rod middle part, sand belt passes through the wire drawing die nib and is connected on the support.Through toggle rotatablely moving of motor is converted into the straight reciprocating motion of guide rod in this device,, realized polishing processing nib through being connected on the guide rod sand belt of doing straight reciprocating motion with respect to nib.But this type of device, because in the drive mechanism of the straight reciprocating motion that realizes polishing tool (instrument silk, sand belt), connecting link is more, synthesis precision is difficult to control, reciprocating in addition frequent switching-over, it is highly steady that running is difficult to reach.Such method of operation is less to the wire drawing die influence of processing common specification, but for the processing of the micropore wire drawing die of aperture≤0.03mm, can't guarantee the smoothness of linear reciprocation operation, thereby can't avoid tool for breaking off silk in the process of processing micropore wire drawing die.
In present wire drawing die manufacturing industry, for a change this situation was also once improved line polisher.For example publication number is a disclosed wire drawing loft polisher lapper in the Chinese utility model patent of CN2419001Y; The guide frame reciprocating mechanism is improved; On original basis, eccentric wheel has been adopted counterweigh, thereby the guide frame high, low speed is operated steadily, range of work broadening; Machining accuracy improves, and processing small-bore wire-drawing die is become a reality.Be in the Chinese invention patent of CN101367181A and for example at publication number; Disclose a kind of support break-in guide wheel that is used for the wire drawing die line polisher,, support break-in guide wheel has been installed in the end of support through on the die holder of existing wire drawing die line polisher, installing support additional; Reduced the area of wire drawing die surface to be machined; Increase the pressure that acts on finished surface, made abrasive material import the processing district more easily, improved working (machining) efficiency thus.But above-mentioned improvement all can't fundamentally be eliminated the line burnishing device and will rotatablely move and change the not stationarity of bringing in the rectilinear motion process into, can't fundamentally avoid fractureing of instrument silk.
