Description

Turret type double trimming shears

Technical Field

The utility model relates to a cold rolling technical field of pickling especially relates to turret type double side cut on the cold rolling combination unit of pickling is cut.

Background

The turret type double trimming shears are key equipment on the pickling and cold rolling combined machine set. The trimming quality of the double trimming shears directly influences the edge quality of the strip and the related processes of subsequent rolling. The turret type double-trimming shears have the advantages that each cutter holder of the turret type double-trimming shears contains 2 sets of cutter discs, one cutter disc is arranged at one line, the cutter discs can be quickly replaced on line, and the maintenance and replacement of the shearing edges are very simple and convenient. The equipment greatly shortens the machine set stop time, and lays a foundation for improving the machine set running speed and the productivity. Therefore, the turret type double trimming shears are the first choice for the pickling and trimming equipment of the pickling and rolling combined unit.

The traditional turret type double-trimming shears have the advantages that the equipment precision is mainly guaranteed by high-precision machining of parts, and the application of high-precision moving parts is less. A closed frame type frame is used for ensuring the precision of the equipment. The cutter head structure is that the lower cutter shaft is fixed, the upper cutter shaft is adjustable, the adjustment mode is that a gear motor drives a worm gear jack, and a disc spring is used for eliminating gaps. In order to ensure the precision, after the cutter head is well adjusted, the cutter head is locked by a hydraulic cylinder. In order to keep the shearing elevation unchanged, the end face of the blade needs to be ground after the blade is worn.

However, the closed frame type frame is difficult to process and manufacture and has heavy weight; the worm gear jack has low precision, a complex structure and low adjustment precision of side clearance and overlapping amount, and the precision of a tool shaft system part is required to be compensated by very high precision, so that the precision of the part is not guaranteed; due to structural limitation, once a pipeline in the closed frame leaks, the cutter head locking device can only be stopped for maintenance, and the production of the whole unit is influenced; the blade grinds the end face, the grinding workload is large, and the use is not economical.

Aiming at the problems in the prior art, a novel turret type double-trimming shear is researched and designed, so that the problem in the prior art is very necessary to be solved.
