TDS SERIES FITTINGS

The TDS series foresees a series of fittings especially useful for specific workings and when some extreme precision and repetitivity are required together with working times extremely low, thence the reheatings of the materials being worked are minimized.
- Upper rotating table qualified for the sensitive manual rotation, with rotation:
o indexed of: 90°+90°+90°+90°
o Controlled on 36'000 positions and then integrated in the general control of the machine
- Side centrators working between the uprights of the machine and able to center and to lift both the devices in the working stations of the principal lower sliding table and the ingots and/or the various pieces being worked. By these fittings it is possible to center, lift and deposit in the middle of the various working stations arranged in the principal sliding table and to obtain then n°3÷4 or even more working operations, without it being necessary an external aid and in a very short time.
- Upper dies bearing rotating arms. The upper mobile table can be equipped with 1 or 2 rotating arms able to hold the various equipment. These ones are very easy to be replaced outside the machine and when desidered each arm will care for the insertion of the desired equipment into the center of the machine under the upper rotating table and therefore the replacement of the upper die will be quick and sequential. In this way particular formings of shaped pieces can be obtained by progressive re-takes.
- Lower ejectors. Various models are available, their dimensional characteristics are various, they can work in the middle and/or outside the machine, however they always work in the middle of the various stations arranged for in the lower principal sliding table. Such ejectors, if properly dimensioned in order to exercise suitable working forces, can be used to carry out drillings by extrusion, working from the bottom upwards, to obtain cylindrical holes without it being necessary to use the charcoal for the extrusion of the extrusion plugs. In this way the working environment will be much more clean if compared to the traditional system.
- Drilling and bottom removing device. Various models of drilling and/or bottom removing devices are available, they can be mounted onto the upper principal vertical mobile table, in order to remove the bottoms left on the piece after the hole extrusion. Our drilling devices are, all of them, equipped with a suitable quick punch and ejection rings replacement system. The working procedure can be programmed in order to be working manually and/or automatically. Drilling and ejection of the punch are carried out without moving at all the piece being worked in order to make it easy the re-taking of the drilled piece even by an eventual automatic manipulation system.
- Dies blocking system. All these last generation machines can be equipped with modern hydromechanic device blocking and unblocking systems which are able to understand when a die is hooked and blocked in every possible machine working station.
- Automatic die replacement system. A suitable series of dies' stocks are available in which it is possible to precharge various dies, in order later on to carry out the automatic die replacement in any moment without any manual human intervention. It results then to be possible replacing a die on which a piece has just been forged and which then is extremely hot. The die replacement can be programmed electronically to be working by automatic cycle too and synchronized with the machine. The above once again to reduce drastically the products manufacturing times and to reduce thence the number of the following reheatings to complete the necessary forging operations.
