Description
Technical field
The present invention relates to a kind of equipment for processing automobile exhaust pipe, specifically a kind of sizing pipe mold.
Background technique
In automobile exhaust pipe production process, flaring sizing is one of important process, for this reason, it may be necessary to use plug die
Tool.Traditional sizing die is typically only capable to carry out simply to be flared sizing, is more valve structures since flaring die has the core that rises, through expanding
Product after mouthful affects product quality, the tube outer diameter size after simultaneous processing is difficult to there is circularity dimensional accuracy is poor
It is accurate to guarantee.
Summary of the invention
The technical problem to be solved by the invention is to provide one kind can be improved pipe fitting circularity after Sizing precision, sizing it is good,
Internal diameter and outer diameter all have the sizing pipe mold of higher dimensional precision.
Sizing pipe mold of the invention includes the undergauge set of coaxial arrangement and the core that rises；The undergauge set is by more valve edges
The undergauge set of modules of circumferential arrangement forms, and the inner cylinder face that the inner surface of each undergauge module surrounds constitutes undergauge working face；Respectively
The outer surface of undergauge module surrounds a male cone (strobilus masculinus), and male cone (strobilus masculinus) periphery is cased with the matched pressure with inner conical surface
Set, the axial movement of pressing sleeve can oppress undergauge module by cone match and inwardly tighten；The core that rises by more valves circumferentially
The flaring module of arrangement forms, and the external cylindrical surface that each outer surface for being flared module surrounds constitutes flaring working face, is flared working face
It is opposite with above-mentioned undergauge working face；The inner surface of each flaring module surrounds an inner conical surface, be inserted in inner conical surface one with
Cooperation the mandril with male cone (strobilus masculinus), the axial movement of mandril can pass through the cone cooperation compressing flaring outside spreading of module.
The same side end of the undergauge module and flaring module is respectively arranged with undergauge module positioning seat and flaring module
Positioning seat is provided with a limit plate between undergauge module positioning seat and flaring module positioning seat, on two end faces of limit plate
Several radial limiting slots are provided with, limiting slot is matched with the spacer pin for being located at undergauge module positioning seat and being flared in module positioning seat
It closes, carry out limition orientation is moved radially to undergauge module and flaring module.
The undergauge module positioning seat and flaring module positioning seat are located in the shell of a pair of of butted structure, undergauge working face
Shell is stretched out with flaring working face；The limit plate and shell, which are worn, connects fixation.
The present invention, can be on a mold in sizing pipe forming process by the undergauge set of coaxial arrangement and the core that rises
It is first flared undergauge again or first undergauge is flared again, enable sizing pipe spot size and shape by rising, contracting is acted and corrected,
To substantially increase the form and dimensional precision of product；It, can be with inside and outside to pipe fitting by the compressing of inside and outside both direction
Diameter size carries out precise forming.
