Abstract
The utility model relates to a kind of 180 ° of bent pipe molds, including die holder (1) and die head (2), the die holder (1) and die head (2) cooperate up and down, die holder forms outer die cavity, die head forms interior die cavity, the outer die cavity and interior die cavity match, the outer die cavity and interior die cavity merge into shaping through slot in the state of pairing inside and outside die holder and die head, the shaping through slot includes the arc groove b mutually in the both ends straight trough a of " eight " word and bottom interlude, and the notch of straight trough a is ellipse.Straight tube shaping can be the bend pipe with specific structure by the molding die of the application, bend pipe obtains final products through full circle process again, relatively direct to be shaped as 180 ° of semicircle bend pipes, and the application can significantly reduce shaping difficulty, lumber recovery is improved, the mutual abrasion between mold and pipe fitting is reduced.
Description
Technical field
The utility model belongs to molding die, and in particular to 180 ° of bend pipe hot forming tools.
Background technique
Pipeline is changed direction during arrangement and is commonly encountered, its deflecting difficulty of the pipeline of unlike material is also different, right
Configuration union elbow is generally required in the high metallic conduit of intensity, connector has the elbow of 90 ° He wide-angle, changes to adapt to 180 °
To, it is also necessary to carry out the design of 180 ° of elbows.
Currently, bend pipe is mainly formed by straight tube thermoforming, the mold of thermoforming is the semicircular arc of standard, and nozzle is also
Circle, the mold are easy to cause " biting " straight tube, and tube wall will appear cutter trade, and the abrasion journey of mold in forming process
Degree is big, and mold is worn mutually with pipe fitting.
Utility model content
Technical problem to be solved in the utility model is that a kind of 180 ° of forming elbow moulds are provided for the above-mentioned prior art
Straight round tube is directly thermoformed into 180 ° of special-shaped bend pipe semi-finished product by tool, the mold, including medial arc bend loss and both ends it is straight
Pipeline section, and straight pipe nozzle is ellipse, it is curved that the oval straight pipes of the two of the semi-finished product using full circle obtain final 180 °
Pipe, the mold of the utility model are mainly used for the thermoforming of aforementioned 180 ° of bend pipe semi-finished product.
The technical scheme in the invention for solving the above technical problem are as follows: a kind of 180 ° of bent pipe molds, including mould
Seat and die head, the die holder and die head cooperate up and down, and die holder forms outer die cavity, and die head forms interior die cavity, the outer die cavity
It matching with interior die cavity, the outer die cavity and interior die cavity merge into shaping through slot in the state of pairing inside and outside die holder and die head,
Shaping through slot includes the arc groove b mutually in the both ends straight trough a of " eight " word and bottom interlude, and the notch of straight trough a is ellipse
It is round.
Preferably, the top of the die head is equipped with pressure-bearing platform.
Preferably, the die holder is supported on bottom plate, makes support more steady, reduces the pressure to ground.
For the ease of the transport of the application mold, the die holder two sides are provided with fork plate, fork plate is relatively higher than die holder bottom
Face.The setting of fork plate can facilitate fork truck to be lifted template.
In use, die head decentralization is until die head and die holder close up, on pressure-bearing platform by the circle straight tube of heating as die holder
Weight is placed by side, and pipe fitting completes shaping in shaping through slot, pipe fitting be shaped as with the matched 180 ° of bend pipes of shaping through slot, two sides are
Straight tube, nozzle are ellipse, and interlude is curved pipe, and nozzle is circle, 180 ° of bend pipes after shaping again by round straight tube shaping,
By the straight tube of ellipse be shaped as round straight tube to get.
Compared with the prior art, the advantages of the utility model are: providing a kind of 180 ° of bent pipe molds, there is spy
The shaping channel of different shape, centre are arc groove, and two sides are straight trough, and the notch of straight trough is ellipse, which can
The mutual abrasion between mold and pipe fitting is reduced, improves the quality of bend pipe, the service life of mold is also extended.
Detailed description of the invention
Fig. 1 is the molding die of existing 180 ° of bend pipes;
Fig. 2 is the schematic diagram of the utility model embodiment molding die;
Fig. 3 is the utility model embodiment molding die partial schematic diagram.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As Figure 2-3,180 ° of bent pipe molds of one of the present embodiment, including mutually independent die holder 1 and mould
First 2 die holder 1 and about 2 die head cooperate, and die holder 1 forms outer die cavity, and die head 2 forms interior die cavity, outer die cavity and interior die cavity phase
It coincide, die head 2 is transferred to 1 on die holder, allow pairing inside and outside die holder 1 and die head 2, outer die cavity and interior die cavity merge into shaping at this time
Through slot, the shaping through slot include the arc groove b mutually in (transition) section among the both ends straight trough a of " eight " word and bottom, and straight
The notch of slot a is ellipse.
The top of die head 2 is equipped with pressure-bearing platform 4, for carrying weight during thermoforming.
1 bottom surface of die holder is welded with bottom plate 5, and for entire molding die by bottom plate as ground, support is more firm.
1 two sides of die holder are provided with fork plate 3, and fork plate 3 is relatively higher than 1 bottom surface of die holder, and the carrying with fork truck to mold.
The application mold can process 180 ° of bend pipes with straight pipe, and the orifice configuration of straight pipe is ellipse,
Facilitate to reduce the mutual abrasion in reforming process between mold and pipe fitting in this way, the surface of pipe fitting is without " trace ", surface quality
More preferably.Subsequent bend pipe for convenience and other circle straight tubes to welding, can by rounding die by straight pipe by oval shaping
For circle, and relative to other full circle, the operation that elliptical tube is shaped as round tube is relatively reduced again to mold, pipe fitting sheet
The abrasion of body.
In addition to the implementation, the utility model further includes having other embodiments, all to use equivalents or equivalent
The technical solution that alternative is formed, should all fall within the protection scope of the utility model claims.
