Safety protection device special for aluminum plate production cold rolling mill and using method

Abstract

The invention relates to the technical field of cold rolling mills, and discloses a safety protection device special for an aluminum plate production cold rolling mill and a using method. The safety protection device comprises a protection column, clamping bases are fixedly connected to the two sides of the protection column, positioning blocks are fixedly connected inside the clamping bases, sliding ways are fixedly connected inside the positioning blocks, and reset springs are fixedly connected inside the sliding ways; a movable contact on a movable plate is in contact with a static contact on a fixed plate, so that the static contact is in contact with the movable contact, a circuit on an electromagnet is switched on, the electromagnet attracts a permanent magnet in a locking block, the permanent magnet drives the locking block to slide towards the inner side, the locking block slides into a clamping groove, and the locking block locks the protection column and the clamping bases; the protection column is fixed by the clamping bases, strong vibration is avoided, safety of the protection device in a working process is improved, the device can prevent strong vibration in a using process, and the device can be flexibly disassembled and moved when not used.

Description

technical field [0001] The invention relates to the technical field of cold rolling mills, in particular to a special safety protection device for cold rolling mills producing aluminum plates and a use method thereof. Background technique [0002] Cold rolling mill is a new type of steel cold rolling processing equipment. The machine can process hot-rolled wire rods and hot-rolled coils with diameters between 6.5 mm and 12 mm into cold-rolled ribbed steel bars with diameters between 5 mm and 12 mm. The cold-rolled ribbed steel bar rolled by a cold rolling mill is an updated product of cold-drawn low-carbon steel wire in prestressed concrete members. In cast-in-place concrete structures, it can replace grade I steel bars to save steel. It is one of the better cold-worked steels of the same kind. If speed regulation is not required during the rolling process of the cold rolling mill, an AC motor can be used; if speed regulation is required during the rolling process of the c...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a special safety protection device for cold-rolling mills for aluminum plate production and its use method, which has the advantages of being locked and fixed when in use, and can be disassembled and installed flexibly when not in use, which solves the problem of After the protective device is fixed, it cannot be moved, which leads to its inflexibility and affects the installation and disassembly of the device when it is not in use.
