Description

Technical field [0001] The rear work roll device of the profile bending machine of the present invention belongs to the technical field of profile bending manufacturing. Background technique [0002] At present, most of the domestic profile bending machines adopt a three-roller (or four-roller) structure with an arc downward adjustment. The cylinder is moved by two rear rollers, and the rear roller can move in an arc around the central axis along the arc groove on the bed. The supporting roller is installed on the bed and placed on both sides of the main roller. It can move up and down and horizontally. The three rollers are all the main driving rollers. The structure is simple and the forming effect is accurate. However, because the model is an integral structure, it can be used as a profile specification. When it is larger, the machine's external dimensions are very large, which is not conducive to installation and transportation. This type of structure is only suitable for the...

Problems solved by technology

The idler roller is installed on the bed and placed on both sides of the main roller. It can move up and down and move horizontally. The three rollers are all the main driving rollers. The structure is simple and the forming effect is accurate. However, due to the overall structure of the machine, when the profile specification When it is larger, the overall size of the machine is very large, which is not conducive to installation and transportation. This type of structure is only suitable for bending small and medium-sized profiles.
