Description
Technical field
The utility model relates to pipe fitting process equipment, in particular to a kind of bending machine.
Background technique
Current bending machine is generally made of pipe bending mechanism and feed device, and operator is by pipe fitting clamping in feed device
After upper, pipe fitting is transported at pipe bending mechanism by feed device, horizontal on one end of lathe to turn after pipe bending mechanism clamps pipe fitting
After dynamic 180 degree, pipe fitting is bent, subsequent pipe bending mechanism unclamps pipe fitting and is back to initial position, while feed device rotates
After pipe fitting, then pipe fitting is placed at pipe bending mechanism, subsequent pipe bending mechanism horizontally rotates again, to realize constantly left and right bending
Pipe fitting.
When pipe bending mechanism bending pipe fitting, when the active force that pipe fitting is subject to and when being less than its yield strength, pipe fitting will
There is restorable trend, it will influence pipe fitting and bend effect.Therefore it needs to be arranged pipe fitting on lathe close to the straight of bending place
The side-pressing device that line segment pushes against, after active force of the pipe bending mechanism to pipe fitting is more than its yield strength, plastic deformation occurs for pipe fitting,
Side-pressing device unclamps again pipe fitting at this time, ensure that the bending effect of pipe fitting.
But when due to the rotation of existing pipe bending mechanism, pipe bending mechanism rotates initial position perpendicular to the length side of lathe
To, and pipe bending mechanism horizontally rotates the length direction that the rotation end position after 180 degree is also perpendicularly to lathe, leads to bending machine
Structure slewing area occupies biggish space on lathe, so that side-pressing device can only be obliquely installed in the side rear of pipe bending mechanism,
The active force that side-pressing device is applied to pipe fitting at this time favours tubular length direction, therefore this active force can generate vertically
In tubular length direction and two component for being parallel to tubular length direction, the active force of side-pressing device is perpendicular to tubular length side
Upward component could play abutting position-limiting action to pipe fitting, in the case where output action power is constant, this active force and pipe
It is stronger to the abutting power of pipe fitting closer to vertical then side-pressing device between part length direction, it is on the contrary then to push against power weaker.Therefore
After side-pressing device is obliquely installed, the abutting power of pipe fitting will be weakened, it is possible to pipe fitting be caused to produce in process
Raw deflection, to influence the quality after pipe fitting processing.
