Abstract
The invention discloses a bending mold of a closed arc part and a process thereof, wherein the bending mold comprises a cylinder rod; the cylinder rod is connected with an upper mold connecting rod and a support rod; a circular groove lower mold is arranged below the cylinder rod; and a semicircular groove fitting the cylinder rod is formed in the circular groove lower mold. The bending mold is simple in structure and low in cost; compared with a traditional rolling mold, the bending mold largely reduces the production cost, and is specifically suitable for small-batch production; and the process is simple in steps, facilitates the production, and improves the production efficiency.
Description
Technical field
The present invention relates to panel beating technical field, especially, relate to a kind of Bending Mould and technique thereof of closed circular arc part.
Background technology
Current panel beating field, makes the closed thin-walled sheet-metal member of long size, and the general mode of roll-forming that adopts is processed, but it is high to relate to roll-in die cost, particularly for processing small batch part situation processing cost larger.
Summary of the invention
The object of the invention is the Bending Mould and the technique thereof that provide a kind of closed circular arc part, to solve in prior art, and the problem that processing cost is high.
For achieving the above object, the invention provides a kind of Bending Mould of closed circular arc part, comprising: cylindrical bar, described cylindrical bar is connected with patrix connecting rod and support bar; Circular groove counterdie is set below described cylindrical bar, described circular groove counterdie offers the half slot matched with described cylindrical bar.
The present invention also provides a kind of bending technique of the Bending Mould based on above-mentioned closed circular arc part, comprises the following steps:
A, be placed between bending upper die and bending " V " shape bed die by workpiece, described bending upper die presses down and is bent one end of described workpiece;
B, be placed between the cylindrical bar of described Bending Mould and circular groove counterdie by the workpiece of bending, patrix connecting rod drives described cylindrical bar to press down, on the workpiece the circular arc of bending and molding side;
C, adjust the position of described workpiece, the circular arc of bending and molding opposite side on the workpiece;
D, adjust the position of described workpiece, make described cylindrical bar be positioned at the centre position of two circular arcs on described workpiece; Described cylindrical bar presses down, and described workpiece bending is until the clamping brace bar that heals up of described workpiece;
E, remove described support bar, continue to press down described cylindrical bar, until healing up of described workpiece is closed.
The present invention has following beneficial effect:
This bent mold structure is simple, and cost is low, and relatively traditional roll-in mould, greatly reduces production cost, be specially adapted to small lot batch manufacture; And processing step is simple, is beneficial to production, improves production efficiency.
