Description

Reducing sleeve

Technical Field

The utility model relates to a rolling machine technical field, concretely relates to reducing cover.

Background

The rolling machine is exactly the receipts material part of coil stock processing lines, rolls up into the coil stock through mechanical system to raw and other materials, and extensive application is in the scroll, the yardage roll, and the plastic material is rolled up, and on the metal coil processing lines, according to actual technological requirement design diversification, the common simple and easy rolling machine that has, hydraulic pressure rolling machine, rolling machine generally have a book internal diameter to the material, roll up the external diameter, roll up material thickness, the width all has strict requirement. The winding machine needs to be combined with the winding core sleeve to be used in the using process, and the winding core is fixed on the winding core sleeve and is wound and unwound through rotation.

The existing winding core sleeve structure is fixed, can only be used for a winding core with one diameter, has small application range, and increases the production cost of the winding core sleeve due to the change of the diameter of the winding core.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problems and providing a reducing sleeve.

The utility model discloses a technical scheme realizes above-mentioned mesh, a reducing cover, including a structure main part, the structure main part includes the inside lining pipe, inside lining pipe outside is equipped with the gasbag, the gasbag outside is equipped with the roof, the roof outside is equipped with the outer tube, be equipped with the multiunit recess on the outer tube, be equipped with the work piece in the recess;

one end of the outer sleeve is provided with a fixed block, and an inflation and deflation nozzle for realizing inflation and deflation is arranged in the fixed block.

Preferably, the fixing block is composed of two groups of fixing half blocks of semicircular structures, and fixing bolts for fixing are arranged between the two groups of fixing half blocks.

Preferably, the top plate and the workpiece are fixedly connected through screws.

Preferably, a plurality of groups of air bag fixing assemblies for fixing the air bag are arranged in the outer sleeve.

Preferably, the cross section of the workpiece is in an isosceles trapezoid structure with a wide upper part and a narrow lower part.

Preferably, the airbag fixing assemblies are of an annular structure, and the airbag fixing assemblies comprise two groups, and the two groups of airbag fixing assemblies are respectively located at two ends of the airbag.

The utility model has the advantages that: fill the gassing to the gasbag through filling the gassing mouth, when aerifing the gasbag, the gasbag promotes the outside removal of roof, outwards ejecting with the work piece when the roof outwards removes for the maximum diameter grow of reducing cover, through the gaseous how much in the adjustment gasbag, the size of adjustment reducing cover diameter to satisfy the user demand that different diameters rolled up the core, improved the application scope of reducing cover, avoid leading to rolling up core cover manufacturing cost to increase because of rolling up core diameter change.
