Abstract
The utility model relates to a small diameter, big nonrust steel pipe clod wash frock of radius -thickness ratio, it includes its characterized in that pipe bending die (1), crease -resistance piece (2), slide (3), presss from both sides tight piece (4) and multisection dnockout core (5), crease -resistance piece (2) is located the inboard that curved some the place ahead is played in pipe bending die (1), slide (3) are located outside that curved some the place ahead is played in pipe bending die (1), and the medial surface of slide (3) is provided with the concave arc face, it is located pipe bending die (1) curved outside to press from both sides tight piece (4), multisection dnockout core (5) are located pipe bending die (1) and play the curved curved some rear that has extended to. The utility model discloses small diameter, big nonrust steel pipe clod wash frock of radius -thickness ratio has the advantage that return bend product quality is good.
Description
Technical field
This utility model relates to a kind of minor radius, big radius-thickness ratio stainless steel tube clod wash frock.
Background technology
The small-bore stainless steel elbow that, radius-thickness ratio little for bending radius is big, when using conventional clod wash mould to carry out bend pipe, easily produces the situation that ovality is overproof.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that the minor radius of a kind of bend pipe good product quality, big radius-thickness ratio stainless steel tube clod wash frock.
The purpose of this utility model is achieved in that
A kind of minor radius, big radius-thickness ratio stainless steel tube clod wash frock, it includes bending die, wrinkle resistant piece, slide plate, clamping block and multi-stage loose-core, the described wrinkle resistant piece of inner side being positioned at bending die inflection point front, described slide plate is positioned at the outside in bending die inflection point front, the medial surface of slide plate is provided with cancave cambered surface, described clamping block is positioned at the outside of bending die inflection point, and described multi-stage loose-core is positioned at bending die inflection point and extends to inflection point rear.
Described slide plate is arranged at one along the slideway of bend pipe feeding travel direction.
Compared with prior art, the beneficial effects of the utility model are:
During the work of this utility model minor radius, big radius-thickness ratio stainless steel tube clod wash frock, fill in stainless steel tube to be curved, stainless steel tube outer surface and slide plate joint by multi-stage loose-core from inflection point.During bend pipe, it is motionless that multi-stage loose-core 5 is positioned at inflection point, owing to aggressive device is positioned on bending die, as long as it is the most overproof to control inflection point ovality, then can ensure that whole bend pipe ovality is the most overproof, and slide plate is for controlling the molding of outer surface.Therefore the advantage that this utility model minor radius, big radius-thickness ratio stainless steel tube clod wash frock have bend pipe good product quality.
Accompanying drawing explanation
Fig. 1 is this utility model minor radius, the top view of big radius-thickness ratio stainless steel tube clod wash frock.
Fig. 2 be bending die with slide plate coordinate schematic diagram.
Wherein:
Bending die 1
Wrinkle resistant piece 2
Slide plate 3
Clamping block 4
Multi-stage loose-core 5.
Detailed description of the invention
See Fig. 1 ~ Fig. 2, a kind of minor radius that this utility model relates to, big radius-thickness ratio stainless steel tube clod wash frock, it includes bending die 1, wrinkle resistant piece 2, slide plate 3, clamping block 4 and multi-stage loose-core 5, described wrinkle resistant piece 2 inner side being positioned at bending die 1 inflection point front, described slide plate 3 is positioned at the outside in bending die 1 inflection point front, namely slide plate 3 is positioned at outside wrinkle resistant piece 2, described slide plate 3 is arranged at one along the slideway of bend pipe feeding travel direction, the medial surface of slide plate 3 is provided with and the cancave cambered surface of stainless steel tube form fit to be curved, described clamping block 4 is positioned at the outside of bending die 1 inflection point, described multi-stage loose-core 5 is positioned at bending die 1 inflection point and extends to inflection point rear.
When a kind of minor radius, the work of big radius-thickness ratio stainless steel tube clod wash frock, fill in stainless steel tube to be curved, stainless steel tube outer surface and slide plate 3 joint by multi-stage loose-core 5 from inflection point.During bend pipe, it is motionless that multi-stage loose-core 5 is positioned at inflection point, owing to aggressive device is positioned on bending die 1, as long as it is the most overproof to control inflection point ovality, then can ensure that whole bend pipe ovality is the most overproof, and slide plate is for controlling the molding of outer surface.
Claims (2)
1. a minor radius, big radius-thickness ratio stainless steel tube clod wash frock, it is characterized in that it includes bending die (1), wrinkle resistant piece (2), slide plate (3), clamping block (4) and multi-stage loose-core (5), described wrinkle resistant piece (2) are positioned at the inner side in bending die (1) inflection point front, described slide plate (3) is positioned at the outside in bending die (1) inflection point front, the medial surface of slide plate (3) is provided with cancave cambered surface, described clamping block (4) is positioned at the outside of bending die (1) inflection point, and described multi-stage loose-core (5) is positioned at bending die (1) inflection point and extends to inflection point rear.
