Abstract
The utility model relates to a hot extrusion die cooling structure, which comprises a die and a pretension sleeve, wherein the die is sheathed with the pretension sleeve which is in interference fit with the die. The hot extrusion die cooling structure has the innovative characteristics that a spiral groove is formed on the inner wall of the pretension sleeve; the spiral groove is matched with the outer wall of the die so as to form a spiral channel; and a water inlet and a water outlet which are respectively communicated with the spiral channel are formed on the outer wall of the pretension sleeve in a drilling manner. The hot extrusion die cooling structure has the advantages as follows: cooling water enters the spiral channel through the water inlet and is discharged through the water outlet after circling the outer wall of the die for a plurality of times, so that the contact time and the process of the die in a cooling water area can be increased greatly, the cooling effect is improved, and the cooling water is saved.
Description
Technical field
The utility model relates to a kind of hot extruding die, particularly a kind of cooling structure of hot extruding die.
Background technology
Hot extruding die is in forging the extrusion modling process of material, and the heat that heating back blank and extruding produce can exert an influence to the material and the hardness of mould, need cool off it, to avoid influencing the service life of mould.Hot extruding die mainly comprises mould and is coated on the outer pre-tightening sleeve of mould that cool off to adopt and establish interlayer at the pre-tightening sleeve center, logical cooling water carries out in the interlayer, interlayer processing inconvenience.
The utility model content
The technical problems to be solved in the utility model provides a kind of hot extruding die cooling structure of simple in structure, good cooling results.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of hot extruding die cooling structure, comprise mould and pre-tightening sleeve, described pre-tightening sleeve is enclosed within outside the mould, and with its interference fit, its innovative point is: described pre-tightening sleeve inwall is processed with a helicla flute, and this helicla flute cooperates the formation helical duct with the outer wall of mould, and at water inlet and the delivery port of pre-tightening sleeve outer wall brill respectively at the helical duct conducting.
Advantage of the present utility model is: cooling water enters helical duct from water inlet, discharges from delivery port around a few backs of mould outer wall, has improved the time of contact and the flow process of cooling waters mould greatly, has improved cooling effect, has saved cooling water.
Description of drawings
Accompanying drawing is the utility model hot extruding die cooling structure schematic diagram.
The specific embodiment
As shown in drawings, comprise mould 1, pre-tightening sleeve 2, helical duct 3, water inlet 4, delivery port 5.
The outline of above-mentioned mould 1 is for slightly having the pyramid type of tapering, its outer pre-tightening sleeve 2 that is with, the inner surface of this pre-tightening sleeve 2 be can chimeric mould 1 profile the pyramid type inner chamber, both utilize also interference fit of tapering sealing.Inwall at pre-tightening sleeve 2 is processed with a helicla flute, and this helicla flute cooperates formation helical duct 3 with the outer wall of mould 1, and at water inlet 4 and the delivery port 5 of pre-tightening sleeve 2 walls brill respectively at helical duct 3 conductings.
Cooling water enters helical duct 3 by water inlet 4, and flows out its flow process L=mould external diameter * pi * helicla flute number of turns from delivery port 5.Increase the time of contact and the flow process of cooling water and mould 1 greatly, improved cooling effect, saved cooling water.
Claims (1)
1. hot extruding die cooling structure, comprise mould and pre-tightening sleeve, described pre-tightening sleeve is enclosed within outside the mould, and with its interference fit, it is characterized in that: described pre-tightening sleeve inwall is processed with a helicla flute, this helicla flute cooperates the formation helical duct with the outer wall of mould, and at water inlet and the delivery port of pre-tightening sleeve outer wall brill respectively at the helical duct conducting.
