An all-in-one machine for unwinding, centering and pinch feeding

Abstract

The invention discloses an uncoiling, centering and pinch-feeding all-in-one machine which comprises a machine frame. Supporting plates driven by first lifting devices are slidably mounted on the two sides of the machine frame, each supporting plate is provided with a precise centering mechanism which is provided with a shovel head mechanism, each shovel head mechanism is located on the upstream portion of the corresponding precise centering mechanism, and two uncoilers are arranged on the upstream portion of each shovel head mechanism. A pinch-feeding mechanism is arranged on the portion, located at the downstream potions of the precise centering mechanisms, of the machine frame and located between the two supporting plates. The precise centering mechanisms are used for conducting forced centering on a plate formed after uncoiling of a hot-rolled stainless steel composite roll and a hot-rolled stainless steel composite plate, the cut-off effect of carbon steel skirts is guaranteed, and finish machining of downstream equipment on hot-rolled stainless steel composite materials and improvement of forming quality of the composite materials are guaranteed. The uncoiling, centering and pinch-feeding all-in-one machine can meet production requirements for hot-rolled stainless steel composite rolls and plates, the investment cost is lowered, the space occupancy rate is decreased, the machine is compact in structure, reasonable in arrangement and good in cooperative work, and production efficiency is effectively improved.

Description

technical field [0001] The invention relates to an unwinding, centering and pinching integrated machine. Background technique [0002] At this stage, hot-rolled stainless steel composite material is a national strategic emerging industry. Because of its good corrosion resistance and low cost, it is widely used in petroleum, chemical industry, salt industry, water conservancy and electric power, food processing and other fields. Hot-rolled stainless steel clad materials generally include two types: hot-rolled stainless steel clad coils and hot-rolled stainless steel clad plates. Figure 20 ): Two layers of carbon steel plates 701 located on the outside, stainless steel plates 702 are provided on the sides of the two carbon steel plates 701 that are close to each other, and the outer peripheries of the two carbon steel plates 701 are welded with carbon steel skirts 703 formed by carbon steel plates, that is to say: The outer periphery is carbon steel plate, and the inner core ...

AI Technical Summary

Problems solved by technology

[0003] At this stage, there is basically no equipment in the industry that can process hot-rolled stainless steel clad coils and hot-rolled stainless steel clad plates at the same time. Generally, it is completed through two production lines. The coil production line processes hot-rolled stainless steel clad coils, and the plate production line processes hot-rolled stainless steel clad coils. Composite board processing requires high investment costs and a large space occupation. Moreover, the equipment that completes each process is an independent unit, and the arrangement is unreasonable and not compact, which leads to poor coordination between various equipment and low production efficiency; at the same time, the existing The equipment cannot achieve accurate centering, resulting in poor cutting effect of carbon steel skirt 703, which in turn causes the downstream equipment to be unable to finish the hot-rolled stainless steel composite material, which greatly affects the molding quality of the composite material
