Fast roll changing device of vertical rolling mill

Abstract

The invention relates to a fast roll changing device of a vertical rolling mill, belonging roll-type forming mill trains. The fast roll changing device of the vertical rolling mill is characterized in that a slide block which corresponds to each roll in position is provided with two sliding roll-box removing mechanisms; each sliding roll-box removing mechanism comprises a roll-box rack, a press plate, a pull rod and a screw; the slide block is movably provided with the roll-box rack which consists of a base plate, a side vertical plate and the press plate and slides along the slide block; the bottom end of a roll shaft is connected into the base plate, and the top end of the roll shaft is connected into the press plate; a locking groove is arranged in the center of the press plate positioned at one side of the side vertical plate; the screw is articulated with the outer side of the lower part of the roll-box rack which corresponds to the locking groove in position; the center of the screw is in female connection with the bottom end of the pull rod; and the pull rod is clamped and locked in the locking groove of the roll-box rack by twisting a step positioned on the top segment of the pull rod. The invention not only has compact, simple and practical design structure and can fast change the rolls and greatly reduce the labor intensity, but also has the advantages of high production efficiency, convenient operation, very convenient use, and the like.

Description

technology field, [0001] The invention belongs to a rolling mill unit for roll forming, in particular to a quick roll changing device for a vertical rolling mill. Background technique [0002] At present, on the roll forming equipment for rolling various profiles, several sets of vertical rolling mills are installed on the stand according to the needs, and the rolling mills are equipped with rolls. Composed of solid nuts and washers, slide blocks are installed in the chute of the machine base. The position of the slide block corresponds to the shape and size of the rolled piece. Vertical rollers are installed on the top surface of the slide block. Bearings are installed in the upper and lower ports of the shaft hole, and the bottom end of the roller shaft equipped with the vertical roller is connected to the slider. The top plate is fixed. But the shortcoming and the weak point of above-mentioned vertical rolling mill are: the roll changing operation is very numerous and d...
