Embodiment 1
[0029] A rolling continuous cold-bending closed rib forming method, the steps:
[0030] 1) Carry out coil uncoiling;
[0031] 2) carry out looper storage;
[0032] 3) Use 10 rolls for the first roll cold bending;
[0033] 4) Use a planer to plan the groove of the steel strip for the first roll cold bending, and control the running speed of the steel strip at 6 m / min;
[0034] 5) Use 2 rolls for the second rolling cold bending;
[0035] 6) Carry out sawing to length and set aside.
Embodiment 2
[0037] A rolling continuous cold-bending closed rib forming method, the steps:

Abstract
The invention relates to a steel strip cold-bending closed rib forming method and an implementing device. The invention solves the shortcoming that the present processing closed rib is low in groove forming rate and cannot guarantee the shape. The measure comprises: a rolling continuous cold-bending closed rib forming method comprising the steps of opening steel coil, loop storage, using 10-14 rollers to implement the first rolling cold-bending, using 1-3 edge planers to plane the groove of the steel strip with the steel strip velocity thereof being controlled in 6-20 meter per minute, using 2-3 rollers to implement the second rolling cold-bending, and sizing and cutting for future use. The device implementing the rolling continuous cold-bending closed rib forming method is mainly composed of an uncoiler 1, a loop container 2, a first cold-bending roller 3, an edge planer 4, a second cold-bending roller 5, a flying saw device 6 and a roller channel 7. The device is connected a steel strip stabilizing device 9 on the edge planer 4 via a connecting shaft 8. The closed rib processed by the invention and the groove thereof are not only online and continuous, but also good in forming property, prominently improved in efficiency and good in surface quality of the product.
Description
technical field [0001] The invention relates to a metal rolling method and device, and more belongs to a steel strip cold-bending closed rib forming method and an implementing device thereof. Background technique [0002] At present, most of the production technology and implementation devices for processing and producing closed ribs still use stamping machines for stamping and cold forming, and its production process has one more production process than ordinary cold-formed steel, that is, the planing process. In this way, not only the pass rate of formability after stamping by a stamping machine is low, but also the labor intensity and cost are high, and the production rate of the closed rib cannot be improved, and the market demand cannot be met. In order to solve this problem, after long-term research, some people have overcome this problem, and added a beveling device to the production line between secondary molding, so as to achieve the purpose of continuously bevelin...
