Skill.
Background technology
Current sheet metal processing field, makes the closure thin-walled sheet-metal member of long size, typically by the way of roll-forming
Processing, but it is related to that roll-in die cost is high, compare especially for processing cost for the situation of processing small batch part
Greatly.
The content of the invention
Present invention aims at a kind of Bending Mould and its technique for closing circular arc part is provided, to solve in the prior art,
The problem of high processing costs.
To achieve the above object, the present invention provides a kind of Bending Mould for closing circular arc part, including：Cylindrical bar, the circle
Mast is connected with upper mould connecting rod and support bar；Set under mould under circular groove, the circular groove and offered on mould below the cylindrical bar
The half slot being engaged with the cylindrical bar.
The present invention also provides a kind of bending technique of the Bending Mould based on above-mentioned closure circular arc part, comprises the following steps：
A, workpiece is placed under bending upper die and bending " V " shape between mould, the bending upper die is pushed the work
One end bending of part；
B, the workpiece of bending is placed under the cylindrical bar of the Bending Mould and circular groove between mould, upper mould connecting rod drives
The cylindrical bar is pushed, on the workpiece the circular arc of bending and molding side；
C, the circular arc of the position, on the workpiece bending and molding opposite side of the adjustment workpiece；
D, the adjustment workpiece position, make the centre position of two circular arc of the cylindrical bar on the workpiece；
The cylindrical bar is pushed, and the workpiece bending is until the clamping brace bar that heals up of the workpiece；
E, the removal support bar, continue to push the cylindrical bar, until the closure of healing up of the workpiece.
The invention has the advantages that：
The bent mold structure is simple, and cost is low, relatively conventional roll-in mould, greatly reduces production cost, special
Shi Yongyu not small lot production；And processing step is simple, beneficial to production, improves production efficiency.

Embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing.
Fig. 1-Fig. 5 is referred to, the preferred embodiments of the present invention provide a kind of Bending Mould for closing circular arc part, including：
Cylindrical bar 4, the cylindrical bar 4 is connected with upper mould connecting rod 3 and support bar 6；The lower section of cylindrical bar 4 sets mould 5, institute under circular groove
State the half slot for offering and being engaged with the cylindrical bar 4 on mould 5 under circular groove.
The preferred embodiments of the present invention also provide a kind of bending technique of the Bending Mould using above-mentioned closure circular arc part, bag
Include following steps：
First step：Workpiece 10 is placed under the bending upper die 1 of conventional bending mold and bending " V " shape between mould 2,
The bending upper die 1 is pushed, and is bent one end of the workpiece 10 using the drift of bending upper die 1；
Second step：The workpiece 10 of bending is placed under the cylindrical bar 4 of the Bending Mould and circular groove between mould 5, on
Mould connecting rod 3 drives the cylindrical bar 4 to push, using the arc-shaped surface of cylindrical bar 4 on the workpiece 10 bending and molding side
Circular arc；
Third step：The position of the workpiece 10 is adjusted, second step bending and molding on the workpiece 10 is repeated another
The circular arc of side；
Four steps：The position of the workpiece 10 is adjusted, two circular arcs for making the cylindrical bar 4 be located on the workpiece 10
Centre position；The cylindrical bar 4 is pushed, and the bending of workpiece 10 is until the clamping brace bar 6 that heals up of the workpiece 10；
5th step：The support bar 6 is removed, continues to push the cylindrical bar 4, until the healing up for workpiece 10 is closed
Close.
This special bent mold structure is simple, and cost is low, relatively conventional roll-in mould, greatly reduces production
Cost, is particularly suitable for use in small lot production；And processing step is simple, beneficial to production, improves production efficiency.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention；For the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
