Abstract
The utility model discloses a tubular product bending mould is formed by bulb (01) of taking the centre bore, a plurality of bowl type spare (02), mandrel (03), sleeve pipe (04), connection handle (05), cable handle (06), cable wire (07) and nut (08) link pack of taking the centre bore. The utility model provides a tubular product bending mould, the rounding off of pipe bending section has been realized to return bend plug mould, has solved that the pipe bending section contracts carefully, bellied problem appears in back crooked tangential point department easily.
Description
Technical field
The utility model bend pipe core rod mould belongs to mould operation technique field, is specifically related to the design of bending pipes mould.
Background technology
In prior art, when manufacturing bend pipe, need Large Diameter Pipeline tube bending, and when bending radius is larger, adopt original inner chamber to support straight plug or link formula plug, after easily occurring, tube bending section shrinking and rear bending point of contact place projection, all accurately cannot meet bending dimensional requirement.
The mode that another kind manufactures bend pipe is, tube bending adopts low-melting alloy to do inner chamber and supports, and the bending section of the bending rear pipe produced so easily occurs shrinking, and after bending section, bending point of contact place also easily occurs the defects such as protruding.
Utility model content
The utility model proposes a kind of bending pipes mould, achieve tube bending section rounding off, solve tube bending section shrinking, protruding problem appears in rear bending point of contact place.
Consider the problems referred to above of prior art, an aspect disclosed in the utility model, the utility model by the following technical solutions:
Bending pipes mould, by the bulb (01) of band centre bore, the bowl-type part (02) of multiple band centre bore, axle (03), sleeve pipe (04), connection handle (05), rope handle (06), cable wire (07), nut (08) is linked and packed and forms, after bowl-type part (02) superposition of multiple band centre bore, bulb (01) with centre bore is placed in the bowl-type part (02) of band centre bore, the bowl-type part (02) of the bulb (01) of the band centre bore assembled and band centre bore is placed on termination with in the axle (03) in bowl-type face, connection is run through by a cable wire (07) in centre, sleeve pipe (04) is fixed in one end, the other end is fixed on the externally threaded rope handle (06) of band, nut (08) is threaded with rope handle (06), axle (03) other end is threaded with connection handle (05), connection handle (05) band internal thread hole, for being connected with bending machine.
The bending pipes mould that the utility model proposes, bend pipe core rod mould achieves the rounding off of tube bending section, solves tube bending section shrinking, protruding problem easily appears in rear bending point of contact place.
Accompanying drawing explanation
Fig. 1 shows bending pipes forming die structure schematic diagram.
Fig. 2 shows the working state schematic representation of bending pipes mould at tube interior.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
See accompanying drawing 1, bending pipes mould, forms by being with the bulb (01) of centre bore, the bowl-type part (02) of multiple band centre bore, axle (03), sleeve pipe (04), connection handle (05), rope handle (06), cable wire (07), nut (08).After 6 bowl-type part (02) superpositions, bulb (01) is placed in bowl-type part (02), the bulb assembled (01) and bowl-type part (02) are placed on termination with in the axle (03) in bowl-type face, connection is run through by a cable wire (07) in centre, sleeve pipe (04) is fixed in one end, the other end is fixed on the externally threaded shank of the key of band (06), nut (08) is threaded with rope handle (06), axle (03) other end is threaded with connection handle (05), and connection handle (05) band internal thread hole is connected with bending machine.
During forming elbow, bending pipes mould is built in tube chamber, the bowl-type part (02) of multiple band centre bore is positioned at the bending point of contact place of pipe, when implementing bending to pipe, pipe is out of shape gradually at bending point of contact place, the bowl-type part (02) of bending pipes mould is along with tube bending, because bowl-type part (02) external diameter deformation can not occur, tube chamber also can remain unified internal diameter when brake forming, and such tube bending section there will not be shrinking phenomenon, rear bending point of contact place also there will not be projection.
Claims (2)
1. bending pipes mould, by the bulb (01) of band centre bore, the bowl-type part (02) of multiple band centre bore, axle (03), sleeve pipe (04), connection handle (05), rope handle (06), cable wire (07) and nut (08) are linked and packed and form, after bowl-type part (02) superposition of multiple band centre bore, bulb (01) with centre bore is placed in the bowl-type part (02) of band centre bore, the bowl-type part (02) of the bulb (01) of the band centre bore assembled and band centre bore is placed on termination with in the axle (03) in bowl-type face, connection is run through by a cable wire (07) in centre, sleeve pipe (04) is fixed in one end, the other end is fixed on the externally threaded rope handle (06) of band, nut (08) is threaded with rope handle (06), axle (03) other end is threaded with connection handle (05), connection handle (05) band internal thread hole, for being connected with bending machine.
2. bending pipes mould as claimed in claim 1, is characterized in that: bowl-type part (02) quantity of described band centre bore is 6.
