Abstract
A pipe end necking die is characterized by comprising two separated concave die necking blocks. A front end guide portion of a central hole is a circular arc with the radius (R) of 140 millimeters, a column through hole is formed behind the central hole, the length of the column through hole is 15 millimeters, the radius (R2) of a chamfer at the tail end of the column through hole is 2 millimeters, and the overall axial length of the concave die necking blocks is 35-40 millimeters. The pipe end necking die has the advantages that more than two heat treatment procedures in an original process are eliminated, operation time is saved, the necking effect is good, and manufacturing cost is saved.
Description
Technical field
The utility model relates to the technical field of engine duct pipe end shrink mouth, particularly a kind of pipe end shrink mouth mould.
Background technology
The specification of certain conduit is ф 12 * 1, material is 1Cr18Ni9Ti, require needs that caliber is reduced to ф 8 from ф 12 according to design drawing, cut-off is larger, former process route is after taking heat treatment to change tubing tissue, and the method by the spinning reducing realizes that reducing processes, need to be according to the processing situation, repeatedly carry out repeatedly heat treatment and spinning reducing, until reach drawing requirement.For this conduit, because the undergauge Amplitude Ratio is larger, is reduced to ф 8.8 and has not just gone down, the undergauge surface quality of conduit is also undesirable simultaneously.
The utility model content
The purpose of this utility model is for the size that guarantees the reducing conduit and surface roughness, improves and makes efficient, reduces production costs, and the spy provides a kind of pipe end shrink mouth mould.
The utility model provides a kind of pipe end shrink mouth mould, it is characterized in that: described pipe end shrink mouth mould comprises, the die contracting piece of two separate types, the front end guidance of centre bore is partly the circular arc of R140mm, the back is cylindrical hole, and cylindrical hole length is 15mm, end chamfering R
2Be 2mm.
The whole axial length of described die contracting piece is 35 ~ 40mm.
It is the conduit of 1Cr18Ni9Ti to material, caliber is reduced to 8 millimeters from 12 millimeters, cut-off is larger, reducing is that the die contracting piece by two separate types carries out radial impact to conduit continuously, two halves die contracting piece makes conduit produce plastic deformation by impacting each time, conduit is constantly sent in mould, and two halves die contracting piece is the bump conduit, until complete whole reducing processing.
The die contracting piece bump conduit that impacts reducing and be with two separate types carries out reducing, and after startup, by sending to, the die contracting piece of two separate types opening and closing repeatedly carries out radial impact to conduit to conduit along axis.The die contracting piece that utilizes circular arc to send structure to carries out undergauge, makes conduit produce certain plastic deformation by impacting each time, finally realizes the undergauge processing of conduit.
Advantage of the present utility model:
Pipe end shrink mouth mould described in the utility model has been cancelled above heat treatment step twice of original technique, saves the operating time, and reducing is effective, saves manufacturing cost.
Description of drawings
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is die contracting piece schematic diagram.
