Description

The electrode holder of discharge processing

Technical field

The present invention relates to a kind of electrode holder of the processing of discharging, particularly a kind of easy and simple to handle, the location is firm and be applicable to the clamp structure of difformity electrode.

Background technology

In the manufacturing work flow of plastics jetting mold, moulding discharge is that industry is generally acknowledged and expended time in most and a most used process, so-called discharge processing, be with an electrode and actions such as mould to be processed constantly repeats to contact, separate toward polyslip mutually, cooperate electric current pass through make electrode and mould produce high-temperature digestion and gasify immediately, because the material of general electrode is a copper, the iron material of the general plastics jetting mold of its electric conductivity is for well, so the loss meeting of mould is many, goes out needed shape and size by mould molding; Yet, electrode for discharge processing grips at present, aim at the fixedly designed electrode holder of discharging processing machine tool of brand though have, but must be when it is bought by external import whole system, because mostly the manufacturing of the present plastics jetting mold in Taiwan is external processing, and its total system costs an arm and a leg, and causes the use popularity rate of industry not high.

For these reasons, present most toolmaker adds man-hour in discharge, still can only rely on traditional do soon, tapping lock screw and vice or drill bit bundle folder fix electrode, but these modes can only be used at the specific electrodes shape, and it all has important disadvantages, cause in the flow process of discharge operation, only expend at the fixing of electrode and just quite bother, and its unstability more may cause damage to the strength member of mould, at above-mentioned various traditional electrode fixed forms, division is as follows:

1, the fixed form of tradition vice holding electrode: be about 3: 2 with its width ratio owing to pass the clamping stroke of vice, even want the electrode of the width 135mm of clamping, then the width of traditional vice will have 100mm approximately, thus, not only heavy and therefore width is too big, but the less electrode of size will have a lot of restrictions in the use, for example: electrode and mould are when seeking the center or the high low head of die surface when big, though it can overcome by the vice that increases electrode length or replacing reduced size, but the processor that generally discharges is just for client's foundry, its mould and electrode provide by the client, and the client generally can't consider the problem of this respect for the processor, moreover the size of electrode lengthening also can increase its cost of manufacture (fee of material and wage all increase), if consider to change vice, represent that then the processor only wants the electrode of clamping rectangle just must prepare the vice of a variety of specifications, in addition its periphery of electrode of rectangle can usually there is no right angle or parallel position for the place of clamping, surface coarse again (as the electrode of CNC milling machine made), so, the clamping effect of tradition vice is also bad, just in case in the discharge process, its electrode comes off because of clamping incessantly produces to move, and will produce the damage that can't remedy to mould!

In addition; in the discharge process; must there be processing liquid discharge constantly to wash away the contact-making surface of electrode and mould; so that the oxide that will be produced in the time of will discharging is got rid of; once oxide is got rid of the untimely contact-making surface that then may be accumulated in mould and electrode because of the oxide of excessively assembling; accumulate fast and produce; cause carbon distribution; especially be directed to circular electrode and (normally be used for making material hole; it is characterized in that not only little but also dark; be very easy to " carbon distribution "); if with traditional vice clamping; then it must come with the oil pipe that discharging processing machine was equipped with the contact-making surface oil spout of collimator electrode and mould is washed away, and the removing effect of this kind mode is limited, and still there are carbon distribution or chip removal (oxide) poor effect in regular meeting and the situation that causes processing to have some setbacks.

Other has a kind of electrode of strip, is called thin slice (Rib), has fixing specification to buy when generally using, and makes the shape of other direction again according to Mould design; If the electrode length after the processing is greater than 80mm when above, then it will be very easy to curl, if length then must be come clamping with very big vice greater than more than the 200mm when (even 300mm), just there are enough clamping faces that electrode holder is straight, but the vice of the usefulness of discharging usually big specification not like this.

2, tapping lock screw is fixed: be opposite face boring, the tapping with the finished product face (with mould contact surface) of electrode, and be fixed on the special conducting rod with screw, as discussed previously, general electrode is provided by the client, and the client that electrode is provided is when may and reckon without the tapping operation, and the processer is not when having other fixed form that is suitable for, can only mend boring in the back side of electrode, thus, the risk that the completed finished product face of injury electrode is not only arranged more may cause progress to postpone to fall behind.

In addition,, will cause electrode to utilize again by turn-over, form waste virtually and hole because international copper valency hurricane rises; And when the size of electrode during approximately greater than the size of a deck, fix then may need two screws, and the distance of these two screws is just in case the instrument that is had with the processor when not being inconsistent, then forms another difficult problem again.

3, fast doing (solid fast) is fixing: in practice processing, often that size is less electrode sticks on the conduction round bar with fast dried, the round bar that promptly can conduct electricity is fixed on the head of Electrical Discharge Machine, with the processing of discharging, but its prerequisite is an electrode can not be too heavy, otherwise may fail to stick, once electrode falls down in the process, can be able to damage (because of copper softer than iron), simultaneously, doing when running into higher temperature (instantaneous temperature of discharge surpasses the fast dried scope that can bear sometimes) soon may go bad, and makes electrode come off.In addition, use fast driedly when sticking together electrode, cause electrode bad sometimes with the conduction of conduction round bar with the conduction round bar, even insulation and can't discharging; In addition, use fast doing to also have a shortcoming, machine and with electrode after round bar separates with conduction when discharge exactly, a little fast spot of doing will be left in the surface of electrode, if in the time of also must using same electrode next time once more, only old fast dried greasiness removal can not to be hurt electrode, membership dues one are turned over trick, quite trouble.
