Problems solved by technology

[0004] However, in the actual operation process, it is very difficult to control the state of "clamping but not tight". Especially in the processing engineering, when encountering different types of steel materials for cold bending, it takes countless times of debugging before In the process of bending, the strength is just right to form a working condition that is relatively close to no wrinkles, and this ideal state will basically not appear in the actual process

Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contribution as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.

[0034] A rib cold roll forming machine such as figure 1As shown, a limiting device 3 and a bending device 2 are provided on the workbench 1, wherein two limiting devices 3 are arranged symmetrically on both sides of the bending device 2, so that the limiting device 3 and the bending device 2 A space is formed between the ribs for the ribs to extend in. When the ribs are placed on the workbench 1, the two limiting devices 3 on one side of the ribs will interfere with the ribs, and...

Abstract

The invention discloses a cold bending forming machine for a rib. The technical scheme is characterized in that the cold bending forming machine comprises a working table, wherein limiting devices are mounted on the working table; a bending device is opposite to the limiting devices; a space for placing the rib is formed between the bending device and the limiting devices; the bending device comprises an eccentric grinding wheel and a driving mechanism for driving the eccentric grinding wheel to rotate; and the side wall of the eccentric grinding wheel presses against the rib in an intermittent manner. According to the cold bending forming machine for the rib, creases generated by bending of the rib is avoided, so that after being formed, the rib is linearly smooth and free of the creases and breakage.

Description

technical field [0001] The invention relates to the technical field of steel structure processing, more specifically, it relates to a rib cold bending forming machine. Background technique [0002] Rib cold bending machine is an important equipment for processing ship ribs. With the development of shipbuilding technology and the needs of actual shipbuilding production, higher requirements are put forward for ship rib processing technology and processing equipment. Since the rib processing is generally three-point bending, for example, the bending dies on the two side frames are used as fulcrums, and the bending dies on the middle frame apply bending force to the profile from front to back. performed by bending. [0003] At present, the CNC rib cold bending machine is mainly used, and the CNC rib cold bending machine is mainly composed of: middle frame, side frame, machine base, bending cylinder, middle clamping cylinder, side clamping cylinder, feed and return cylinder , h...
