Abstract
The utility model relates to a flaring die for a special-shaped bent pipe, which consists of a horizontal pipe liquid filling former, an upper die, a lower die, a push head and a sealing ring, wherein the lower die is arranged on the horizontal pipe liquid filling former and is positioned through a boss at the bottom of the horizontal pipe liquid filling former; one end of the push head is arranged at the butting joint of die orifices of the upper die and the lower die; and the sealing ring is arranged in a ring-shaped groove at the end head of the push head. Compared with the existing die, due to the process advancement of the flaring die for the special-shaped bent pipe, the problem of clamping and fixing the bent pipe is completely solved, the formation of bent pipe parts with high material strength and complex shapes can be completed, and the flaring die for the special-shaped bent pipe has the advantages of high forming quality, high precision, small rebounding and the like.
Description
Technical field
The utility model relates to special bent pipe enlarging technology, and a kind of special bent pipe enlarging mould is provided especially.
Background technology
The complicated shape bend pipe is used more at Aero-Space, automobile making, electrical apparatus industry, according to actual instructions for use, bend pipe length is shorter, and general line is with the bend pipe segmental machining in the process, and butt joint is welded then.For making things convenient for the welding between bend pipe, all an end of every section bend pipe to be carried out enlarging.The enlarging mode that extensively adopts is a punching block enlarging technology at present, promptly by the effect of mould to the critical point, makes the material imposed deformation, yet, for the complicated shape bend pipe, adopt existing technology to have two problems.The one, because the tubing clamping problem that the scrambling of tubing shape is brought.For the straight wall pipe of regular shape, can fix pipe fitting by the mode of bottom support, guarantee the location of tubing in the reaming process.And the axis of the non-straight wall pipe of complicated shape does not overlap with the flaring die loading direction, adopts the mode of bottom support can cause tubing unstable failure in the enlarging process.Improved procedure is axially to grip in flared end at present, and this mode is proper for easy enlarging tubing, and higher for the intensity of material, the tubing of easy-formation has not brought second problem, i.e. the problem that tubing clamping does not live.Can't realize that when axial chucking power is not enough tubing fixes, chucking power is much can to cause the tubing distortion again.
The utility model content
The utility model has designed a kind of complicated shape bend pipe enlarging mould of novel basic liquid-filling shaping, and bend pipe is difficult for the problem of clamping when having solved the rigid die enlarging.For the enlarging of complicated shape bend pipe, the utility model adopts the process of super-pressure topping up bulging.
A kind of special bent pipe enlarging mould described in the utility model is made up of horizontal pipe liquid filled make-up machine (1), patrix (2), counterdie (3), cut somebody's hair (4), sealing ring (5), wherein counterdie (3) is installed on the horizontal pipe liquid filled make-up machine (1), boss location by horizontal pipe liquid filled make-up machine (1) bottom, (4) one ends of cutting somebody's hair are installed in patrix (2) and counterdie (3) die orifice joint, and sealing ring (5) is installed in (4) termination cannelure of cutting somebody's hair.
(4) other end of cutting somebody's hair of special bent pipe enlarging mould described in the utility model connects oil fuel tube (6), and tubing (7) is contained in patrix (2) and counterdie (3) die orifice place, and dock (4) with cutting somebody's hair.
The patrix (2) of special bent pipe enlarging mould described in the utility model and counterdie (3) are by alignment pin (8) location, and fixing with bolt I (9), counterdie (3) is connected with bolt II (10) with horizontal pipe liquid filled make-up machine.
Advantage of the present invention: the utility model because of its technologic advance, has thoroughly solved the problem that grips of bend pipe compared with prior art.Can finish strength of materials height, complex-shaped bend pipe part forming, and have advantages such as forming quality is good, precision is high, resilience is little.

The specific embodiment
The described a kind of special bent pipe enlarging mould of present embodiment is made up of horizontal pipe liquid filled make-up machine (1), patrix (2), counterdie (3), cut somebody's hair (4), sealing ring (5), wherein counterdie (3) is installed on the horizontal pipe liquid filled make-up machine (1), boss location by horizontal pipe liquid filled make-up machine (1) bottom, (4) one ends of cutting somebody's hair are installed in patrix (2) and counterdie (3) die orifice joint, and sealing ring (5) is installed in (4) termination cannelure of cutting somebody's hair.
(4) other end of cutting somebody's hair of the described special bent pipe enlarging of present embodiment mould connects oil fuel tube (6), and tubing (7) is contained in patrix (2) and counterdie (3) die orifice place, and dock (4) with cutting somebody's hair.
The patrix (2) of the described special bent pipe enlarging of present embodiment mould and counterdie (3) are by alignment pin (8) location, and fixing with bolt I (9), counterdie (2) is connected with bolt II (10) with horizontal pipe liquid filled make-up machine (1).
(4) axial feed of during enlarging, cutting somebody's hair seals to the fixed position, and oil fuel tube (6) is squeezed into highly pressurised liquid by (4) the interior oilhole of cutting somebody's hair, and forces mouth of pipe distortion enlarging, and (4) feeding of cutting somebody's hair in mouth of pipe distortion guarantees sealing.
Claims (3)
1. special bent pipe enlarging mould, it is characterized in that: special bent pipe enlarging mould is made up of horizontal pipe liquid filled make-up machine (1), patrix (2), counterdie (3), cut somebody's hair (4), sealing ring (5), wherein counterdie (3) is installed on the horizontal pipe liquid filled make-up machine (1), boss location by horizontal pipe liquid filled make-up machine (1) bottom, (4) one ends of cutting somebody's hair are installed in patrix (2) and counterdie (3) die orifice joint, and sealing ring (5) is installed in (4) termination cannelure of cutting somebody's hair.
2. according to the described special bent pipe enlarging of claim 1 mould, it is characterized in that: described cutting somebody's hair (4) other end connects oil fuel tube (6), and tubing (7) is contained in patrix (2) and counterdie (3) die orifice place, and dock (4) with cutting somebody's hair.
