Quick-changing device of cold roll forming horizontal rack

Abstract

The invention relates to a quick-changing device of a cold roll forming horizontal rack. The quick-changing device of the cold roll forming horizontal rack is characterized in that the quick-changing device is composed of on-line horizontal rack flocks and off-line horizontal rack flocks which are the same with the on-line horizontal rack flocks. Multiple horizontal rack groups with parallel arrangement and same intervals are arranged in an installing mode on a base seat of each flock of a horizontal rack flock, wherein each horizontal rack group is composed of 2-4 quick-changing horizontal racks. Each quick-changing horizontal rack is composed of a support beam, a location pin component, a bolt, a quick-changing base plate, a rack, an engine base, a roller, a ring, a clamping mechanism driven by a hydraulic cylinder, and a guiding plate. The quick-changing device of the cold roll forming horizontal rack has the advantages of being reasonable in design and compact in structure. The horizontal racks are convenient to change quickly, and continuous production of a production line is achieved as well. The quick-changing device of the cold roll forming horizontal rack is also fast to change for the racks, high in quick-changing accuracy, capable of achieving quickly changing of standardized horizontal rack modularization, capable of greatly shortening downtime of changing roller standards and improving production efficiency and reducing manufacturing cost, safe to operate, convenient to use and like.

Description

technical field [0001] The invention belongs to cold-bending forming production line equipment, in particular to a quick-change device for a cold-bending forming horizontal frame suitable for a cold-bending forming special-shaped pipe 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 number rangi...

Problems solved by technology

In this way, when the production product changes and the rolls need to be replaced, the working cold roll forming production line will be shut down, and the horizontal racks will be decomposed one by one on the stopped production line to replace the rolls. It is necessary to stop for a long time to meet the needs of changing rolls. , which will seriously affect the efficiency of the production line; at the same time, the production line is surrounded by equipment such as drive shafts, gearboxes, motors and other equipment, resulting in limited space for online replacement and adjustment of rolls, and the operation is very inconvenient and unsafe. The restriction also affects the measurement and adjustment of the roll position accuracy, which ultimately affects the product accuracy and production stability, reducing the yield of the production line; in addition, the production line is suitable for the production of products with multiple varieties and specifications, and the number of forming frames used for different products Different, when producing products with a small number of forming racks, the redundant racks installed on the large base at the front become an obstacle. Usually, flat and straight rolls are installed to ensure the smooth passage of the strip. In this way, the number of rolls Increase the investment and increase the workload of changing rolls
