Abstract
The utility model discloses a kind of rectangular tube ellipse forming frock, an elliptical modes skeleton is welded with base, a symmetrical otic placode is welded with the elliptical modes skeleton, connecting plate is welded with the head end of otic placode, bolt hole is machined with connecting plate, the end of the otic placode is machined with otic placode fraising, and the internal diameter two ends of the elliptical modes skeleton are machined with fraising, A, B hole is machined with lever, lever is equipped with briquetting roller with the cylindrical contact position of elliptical modes skeleton.Wheel shaft is housed on the briquetting roller and is fixed with lever by bearing.Oval moulding on rectangular tube is to be respectively articulated with to complete by A, B fraising on lever with elliptical modes skeleton and otic placode fraising.The technical program can make rectangular tube ellipse moulding rapid shaping, with easy to process, shorten the production cycle, so as to reduce production cost.
Description
Technical field
This utility model is related to a kind of oval forming frock, is particularly well-suited to using during rectangular tube ellipse molding.
Background technology
At present, the supporting space capsule drivers' cab of European crane because curve it is smooth, it is handsome in appearance and it is deep be highly commended by customers, but
The skeleton manufacturing procedure of its elliptic curve moulding is loaded down with trivial details, long the production cycle, so as to increased the production cost of product.
The content of the invention
Task of the present utility model is to propose a kind of a kind of easy to process, rectangular tube ellipse molding work of reduction production cost
Dress.
Task of the present utility model be done in such a way that it is characterized in that：An elliptical modes skeleton is welded with base, it is described
A symmetrical otic placode is welded with elliptical modes skeleton, connecting plate on the head end of otic placode, is welded with, bolt hole on connecting plate, is machined with, it is described
The end of otic placode is machined with otic placode fraising, and the internal diameter two ends of the elliptical modes skeleton are machined with fraising, A, B are machined with lever
Hole, lever are equipped with briquetting roller with the cylindrical contact position of elliptical modes skeleton.On the briquetting roller equipped with wheel shaft and pass through bearing and
Lever is fixed.Oval moulding on rectangular tube is by A, B fraising on lever and elliptical modes skeleton and otic placode fraising difference
It is hinged to complete.
This utility model has the effect that：The technical program can make rectangular tube ellipse moulding rapid shaping, with processing
It is convenient, shorten the production cycle, so as to reduce production cost.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Drawing explanation：1st, otic placode, 2, connecting plate, 3, rectangular tube, 4, elliptical modes skeleton, 5, fraising, 6, otic placode fraising, 7, thick stick
Bar, 8, briquetting roller.
Specific embodiment
Embodiment is described in detail with reference to the figures above, the technical program is applied to rectangle of the thickness between 0.5-2.0mm
Pipe ellipse moulding, as shown in figure 1, an elliptical modes skeleton 4 is welded with base, is welded with a symmetrical ear on the elliptical modes skeleton
Plate 1, is welded with connecting plate 2 on the head end of otic placode, bolt hole is machined with connecting plate, and the end of the otic placode is machined with otic placode fraising
6, the internal diameter two ends of the elliptical modes skeleton are machined with fraising 5, and aid adopts lever 7, and A, B fraising is machined with lever 7,
Lever is equipped with briquetting roller 8 with the cylindrical contact position of elliptical modes skeleton, wheel shaft is housed on the briquetting roller and passes through bearing and thick stick
Bar is fixed.
4 fraisings are machined with the elliptical modes skeleton 4, two of which is provided in the end of otic placode, two other hinge
Hole is provided in the two ends of elliptical modes skeleton diameter, A, B on auxiliary tool lever fraising respectively with elliptical modes skeleton and otic placode
On hole be hinged, so as to complete the oval moulding of rectangular tube.
During work, rectangular tube 3 is placed on elliptical modes skeleton, is entered by the bolt assembled in the bolt hole on connecting plate
Row is fixed.Fraising B on lever is hinged with otic placode, operator promote lever pass through briquetting roller by workpiece（Square
Shape pipe）Upside curve required for being processed into.Then the fraising A on lever is hinged with the fraising on elliptical modes skeleton, is operated
Left side section curve is completed, is continued to be hinged another on fraising B and otic placode, is operated and complete lower portion curve, finally
Another on fraising A and elliptical modes skeleton is hinged, is operated and is completed right part curve.So far whole rectangular tube is ellipse
Circle moulding can be completed.Fixing device is unclamped by workpiece（Rectangular tube）Remove from base and complete whole process.
