Straightener capable of changing rolls quickly

Abstract

The invention discloses a straightener capable of changing rolls quickly. The straightener comprises a driving side frame, a rolling ring assembly, a sliding seat, an operation side frame, a transverse shifting device and an onboard roll changing device, and the on-board roll changing device comprises a roll changing trolley, a lifting device and a rolling ring storage table. The rolling ring storage table is arranged on a lifting device, and the roll changing trolley matches with the sliding seat in a reciprocating slide manner and is arranged on the sliding seat. The onboard roll changing device further comprises a positioning rolling ring storage table and a storage table positioning device opposite to the roll changing trolley in the horizontal direction. When rolls are changed, the rolling ring storage table is lifted to contact with the rolling ring assembly, then a locking device is released from a dragging rod, and the rolling changing trolley and the operation side frame are dragged by the transverse device to move horizontally to separate the rolling ring assembly from the dragging rod, so that the rolling ring assembly and the rolling ring storage table can be hoisted away in one piece. The straightener is simple and convenient in roll changing operation, and short in roll changing time; working efficiency of roll changing and device utilization efficiency can be improved; and the straightener has the advantages of small size, low cost and the like.

Description

technical field [0001] The invention relates to a straightening machine, in particular to a straightening machine which can quickly change rolls. Background technique [0002] For the straightening of large-size profiles, simply supported structure (also known as gantry type) roller leveler is generally used. The traditional simply supported structure roller leveler has the following disadvantages: 1) It adopts mechanical or semi-automatic locking structure ( Such as hydraulic nuts), not only the locking time is too long, which affects the productivity, but also often does not lock tightly, which has potential safety hazards; 2) When replacing the straightening roller, the mechanical equipment needs to be disassembled, and the replacement time of the straightening roller is as long as one day, which affects the The normal production rhythm of the enterprise leads to low production efficiency; 3) The weight of the equipment is heavy, the investment is high and the operation i...
