Description
Technical field
The utility model belongs to spinneret processing technique field more particularly to a kind of electric spark for making Special-shaped hole spinneret plate
Lathe.
Background technology
The effect of spinneret is by the high polymer molten or solution of viscous state, and being transformed by spinneret orifice has particular cross section shape
Thread, be solidified to form strand by setting medium such as air or coagulating bath.
As shown in figure 3, the process of special-shaped spinneret orifice drills out a thicker blind hole to be first from 20 front of spinneret, so
After invert spinneret, using blind hole as location hole 21, by positioning finger setting, made in spinneret reverse side by electric spark galvanic corrosion
Special-shaped micropore 22.
The easy blockage positioning hole of waste material that traditional spark-erosion machine tool generates during galvanic corrosion, influences the processing of special-shaped micropore
Quality, midway clear away waste can then reduce efficiency.
Utility model content
Based on this, for above-mentioned technical problem, a kind of spark-erosion machine tool for making Special-shaped hole spinneret plate is provided.
In order to solve the above technical problems, the utility model adopts the following technical solution：
A kind of spark-erosion machine tool for making Special-shaped hole spinneret plate, including:
Form the board of cathode；
Electrode tip holder has the electrode for forming anode on the electrode tip holder, and the electrode is arranged vertically, cross section and abnormity
The shape adaptation in hole, the electrode tip holder are fixed on an elevating mechanism, which is fixed on the board by supporting rack
Top；
Pedestal, the pedestal are set on the board, have the positioning pin that the electrode is corresponded in lower section thereon, described fixed
With the body of rod and the conical head that is connected at the top of the body of rod, the circumferential surface of the body of rod has plane and is connect with plane position pin
Arcwall face.
The plane and arcwall face are three, and three planes are located at three sides of the body of rod circumferential surface, three arcs respectively
The arc length in shape face is equal, and respectively between adjacent plane.
The elevating mechanism is linear motor or cylinder.
The blowdown that the waste material that the utility model generates during galvanic corrosion can be formed from the hole wall of plane and location hole leads to
Drain in road, do not interfere with the processing quality of special-shaped micropore, it is efficient without shutting down waste material.
Description of the drawings
The utility model is described in detail with reference to the accompanying drawings and detailed description：
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram of the cross section of the positioning pin of the utility model；
Fig. 3 is the structure diagram of special-shaped spinneret orifice.
Specific embodiment
As shown in Figure 1, a kind of spark-erosion machine tool for making Special-shaped hole spinneret plate, including board 110, electrode tip holder 120, pedestal
130 and positioning pin 140.
Board 110 forms cathode.
There is the electrode 121 for forming anode, electrode 121 is arranged vertically, the shape of cross section and irregularly-shaped hole on electrode tip holder 120
Shape is adapted to, and electrode tip holder 120 is fixed on elevating mechanism 150, which is fixed on board 110 by supporting rack 160
Top.
Specifically, elevating mechanism 150 uses linear motor or cylinder.
Pedestal 130 is set on board 110, has the positioning pin 140 in lower section counter electrode 121 thereon.
Positioning pin 140 has the body of rod 141 and is connected to the conical head 142 at 141 top of the body of rod, all masks of the body of rod 141
There are plane 141a and the arcwall face 141b being connect with plane 141, plane 141a and the hole wall of location hole 21 to form blowdown channel
R。
As shown in Fig. 2, in the present embodiment, plane 141 and arcwall face 142 are three, and three planes 141 distinguish position
In three sides of 141 circumferential surface of the body of rod, the arc length of three arcwall faces 142 is equal, and respectively between adjacent plane 141.
In use, reversion spinneret 20, makes positioning pin 140 stretch into location hole 21, electrode 120 is enable to be directed at special-shaped micropore
22 predeterminated position, starting elevating mechanism 150 makes electrode 121 move closer to spinneret 20, and electrode 121 is anode, and board 110 is
Cathode, when two interpolar pulsed discharges, generate galvanic action, so as to make special-shaped micropore 22, due to having plane on positioning pin 140
141a, the waste material that galvanic corrosion generates can drain out of the hole wall of plane 141a and location hole 21 are formed blowdown channel R, Bu Huiying
The processing quality of special-shaped micropore 22 is rung, it is efficient without shutting down waste material.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Utility model, and being not used as the restriction to the utility model, if in the spirit of the utility model, to
Variation, the modification of the upper embodiment will be all fallen in the Claims scope of the utility model.
