Roll changing device of cold roll forming quick-changing rack

Abstract

The invention relates to a roll changing device of a cold roll forming quick-changing rack. The roll changing device of the cold roll forming quick-changing rack is characterized in that each rolling-over table-type roll changing device of an off-line roll changing area is composed of a rolling-over table component and hydraulic rolling-over mechanisms, a gear rack side out mechanism and an undertake groove are installed at one end of the rolling-over table component, and roll shaft side support device is installed at the other end of the rolling-over table component, the rolling-over table component is composed of a pin shaft, a rolling-over table, a steel rail, a bolt, a guiding plate, a location pin shaft and a C-shaped plate, each hydraulic rolling-over mechanism is composed of a hydraulic cylinder, a location seat, a support, a pin shaft, a lug ring and a cushion plate. The roll changing device of the cold roll forming quick-changing rack is not only reasonable in design and compact in structure, capable of achieving vertical axial position changing rollers in the best state and avoiding impact damage of cantilever changing rollers to bearings of roll shafts and capable of using the hydraulic cylinder to drive the rolling-over rack components and the gear rack side out mechanism to drag out the side out rack. The roll changing device of the cold roll forming quick-changing rack has the advantages of being easy to process and manufacture, stable in performance, convenient to adjust accurately for roll gaps, good in product quality, high in efficiency, low in manufacturing cost, safe in operation, convenient to use and the like.

Description

technical field [0001] The invention belongs to cold-bending forming production line equipment, in particular to a roll changing device for a cold-bending forming quick-change frame suitable for a cold-bending forming special-shaped pipe material production line. Background technique [0002] As we all know, in the cold-formed special-shaped pipe production line, because the cross-section of the special-shaped pipe is more complicated and there are more bends, the required forming passes, that is, the number of forming frames, is relatively large, such as the general standard profile parts stipulated in the product standards. Sections of special-shaped pipes such as round pipes, rectangular pipes, steel door and window frames used in construction, automobile and other industries, complex-shaped P-shaped pipes, and 8-shaped pipes. At present, a cold-bending production line is usually used for production. The structure of the cold-forming production line includes a base and a ...

Problems solved by technology

Through the above-mentioned horizontal rack quick-change device, although the cold-formed special-shaped pipe production line has improved, the roll change on each quick-change rack still adopts the traditional and common production line to change rolls one by one. Method—that is, one side of each quick-change rack is fixed to the fixed rack in place, and after the side-out rack on the other side is removed from the original place, it is passed manually and on the horizontal roller shaft of the fixed rack The crane loads and unloads the rolls to realize the roll change; this method of changing the rolls on the horizontal axis of each frame of the production line, in addition to the need for the production line to stop, and in the process of changing the rolls, it is time-consuming and laborious and inconvenient to change the rolls
