Abstract
The utility model relates to a strong-cold type round die tool. The strong-cold type round die tool comprises an upper ring block and a lower ring block which are spaced from top to bottom, wherein a cooling block device is arranged between the upper ring block and the lower ring block and is provided with an inner cooling ring and an outer cooling ring which are mutually embedded from inside to outside; four groups of ring-shaped cooling pipelines are arranged between the inner cooling ring and the outer cooling ring along the axial direction; the ring-shaped cooling pipelines positioned at the upper end and the lower end are cooling-oil inlet pipelines and the two groups of ring-shaped cooling pipelines positioned at the middle part are cooling-oil outlet pipelines; the inner walls of the upper ring block, the lower ring block and the inner cooling ring form an inner ring of a threading die. The strong-cold type round die tool has the advantages that the structure is simple, and by the adoption of the structure form of splitting, a round die body can be provided with the cooling pipelines at an inner cavity, and the round die maintains certain temperature all the time in working, so that the stability of working of the round die is improved, the service life of the round die is prolonged, and further the strong-cold type round die tool is more applicable to the condition of high-speed tapping.
Description
Technical field
The utility model relates to a kind of strong cold mould circular die instrument.
Background technology
In known technical field, circular die is screw die, is again to process or revise externally threaded screwing tool.Circular die is equivalent to one and has the very nut of high rigidity, and screw is shaped with several chip-removal holes around, generally at the two ends of screw mill, has cutting cone.Traditional circular die is generally the design of ordinary construction formula, when attacking the double-screw bolt to be processed that diameter is large, thread segment is long, in the final stage of circular die work, excess Temperature often, especially when mechanized operation, temperature more very, easily reduces intensity and the service life of circular die.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, a kind of strong cold mould circular die instrument is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of strong cold mould circular die instrument, comprise, lower spaced upper annulus piece and lower annulus piece, between annulus piece and lower annulus piece, be provided with cooling block device on described, in described cooling block device has, the interior air ring of outer mutually nested setting and outer air ring, between described interior air ring and outer air ring and be provided with vertically four groups of annular cooling conduit roads, be positioned at, the annular cooling conduit road at lower two ends is cooling-oil inlet pipeline, and two groups of annular cooling conduit roads that are positioned at middle part are cooling-oil outlet pipeline, between the cooling-oil inlet pipeline that top is adjacent and cooling-oil outlet pipeline, be interconnected, and be interconnected between the cooling-oil inlet pipeline that bottom is adjacent and cooling-oil outlet pipeline, described upper annulus piece, together with the inwall of lower annulus piece and interior air ring, form threading die inner ring.
Further, as a kind of concrete embodiment, described in the utility model, between upper annulus piece, lower annulus piece and outer air ring, by fastening bolt, connect.
Further, as a kind of concrete embodiment, described in the utility model, interior air ring is weldingly fixed between annulus piece and lower annulus piece.
The beneficial effects of the utility model are: the utility model is simple in structure, adopt the version of splicing, make circular die body in chamber, cooling pipe is set within it, make circular die when work, all the time maintain certain temperature, the stability of raising work and the service life of circular die, make it be more suitable for the situation of High Speed Threading.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
