Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model.
1-3, the bending device for the chain hoist chain bag comprises a female die mould 1, wherein a male die mould 2 is arranged right above the female die mould 1.
The female die 1 comprises a base 11, two parallel rollers 13 are arranged above the base 11, the end parts of the rollers 13 are rotatably connected to a supporting seat 12, the supporting seat 12 is fixed on the base 11, a lower bending block 15 is arranged between the two rollers 13, and the upper surface of the lower bending block 15 is an inclined lower bending surface 14.
The male die 2 comprises an upper bending block 21, the lower surface of the upper bending block 21 is an inclined upper bending surface, two round tubes 22 are fixed at the edge of the upper bending surface, the round tubes 22 are parallel to the roller 13, the lower bending surface 14 is parallel to the upper bending surface, a connecting column 23 is fixed on the upper surface of the upper bending block 21, and a connecting plate 24 is fixed at the upper end part of the connecting column 23.
In order to prevent scratching the workpiece, a film coating layer (not shown) is provided on the outer sides of the lower bending surface 14 and the upper bending surface.
For convenience in processing, the round tube 22 is a steel tube and is welded to the upper bending block 21.
The working principle is as follows:
and (2) mounting: the connecting plate 24 of the male die 2 is fixed at the piston end of the hydraulic cylinder, the female die 1 is arranged right below the male die 2 and fixed on the frame, and the round tube is properly selected, so that the radius of the round tube 22 is matched with the transition arc radius of the workpiece.
When in operation, the device comprises:
s1, the piston end of the hydraulic cylinder contracts to pull the male die 2 to a high position, so that space is reserved for placing a workpiece (bent plate).
S2, placing the workpiece on the two rollers 13.
And S3, starting the hydraulic cylinder, wherein the piston end of the hydraulic cylinder extends downwards to move the male die 2 downwards, the upper bending block 21 presses the workpiece to start bending, and when the male die 2 moves downwards to a limit position (namely, the lower bending surface 14 and the upper bending surface clamp the workpiece), the upper bending block 21 finishes bending.
During the downward movement of the workpiece, the roller 13 is forced to rotate and remain relatively stationary with the workpiece, where the workpiece is not scratched; the upper bending surface is provided with a round tube 22, and the workpiece is not scratched.
S4, the piston end of the hydraulic cylinder contracts, the male die 2 is pulled to a high position, and the workpiece is taken out.
