Shi Qidong cutting mechanisms, the working tool of cutting mechanism cut plate along the thickness direction of plate to be processed, by the of first section
A straight edge section is cut；Then start veneer reeling machine, roller continues to drive rolling plate into longitudinal, and cuts plate again reaching the when of needing length
Section, can cut multistage in coiling process, until being to the last left the second straight section.
In this way, the plate bending machine can cut straight section, without carrying out prebending process, the complexity of technique is reduced
Property, and straight flange phenomenon is completely eliminated by the way of cutting out, eliminate influence of the straight flange phenomenon to subsequent technique process；Together
When, it can be cut according to use demand multistage in process, improve process continuity, improve processing efficiency.
Optionally, the roller includes upper roller, the first side roller and the second side roller, the roll center of the upper roller, described
The line of the roll center of one side roller and the roll center of second side roller forms triangle；The plate to be processed is described in
It is passed through between upper roller and two side rollers.
Optionally, the triangle is isosceles triangle or equilateral triangle.
Optionally, further include lower roll, the plate to be processed is passed through between the upper roller and the lower roll.
Optionally, the line between the roll center of the upper roller and the roll center of the lower roll, perpendicular to two side rollers
Roll center between line.
The present invention also provides a kind of automation roll bending techniques, include the following steps：
S1：Plate to be processed without pre-bending is inserted into veneer reeling machine, veneer reeling machine is started, the drive roll of veneer reeling machine starts to turn
Dynamic, equipment rolls steel plate；
S2：When the first straight section of plate to be processed is pushed out to place of incision by veneer reeling machine, veneer reeling machine stops operating, and opens
The working tool of dynamic cutting mechanism, the working tool, will described first directly towards the thickness direction downlink of plate to be processed
Side section is cut；
S3：It is again started up veneer reeling machine, the rotation of veneer reeling machine drive roll, and continues to roll plate to be processed, while measuring and rolling out
The length of plate is stopped operating, opens the work of cutting mechanism again when plate to be processed is when rolling out length and reaching preset requirement
Cutter cuts forming panels；
S4：Step S3 is repeated, until legacy part is the second straight section of the plate to be processed, machines and shuts down.
Further, the veneer reeling machine applied in step S1-S4 is three rolls plate bending machine or four-roll plate bending machine.
During the work time, plate to be processed rolls under the drive of roller, when plate enters veneer reeling machine and marches to
When one predeterminated position, it is the first straight section of plate to be processed that first predeterminated position is corresponding, suspends veneer reeling machine and same at this time
Shi Qidong cutting mechanisms, the working tool of cutting mechanism cut plate along the thickness direction of plate to be processed, by the of first section
A straight edge section is cut；Then start veneer reeling machine, roller continues to drive rolling plate into longitudinal, and cuts plate again reaching the when of needing length
Section, can cut multistage in coiling process, until being to the last left the second straight section.
In this way, the roll bending technique can cut straight section, without carrying out prebending process, the complexity of technique is reduced
Property, and straight flange phenomenon is completely eliminated by the way of cutting out, eliminate influence of the straight flange phenomenon to subsequent technique process；Together
When, it can be cut according to use demand multistage in process, improve process continuity, improve processing efficiency.
