The utility model discloses can dismantle the copper slider fast conveniently, increase substantially work efficiency.

Description

Flat head copper slide block dismounting structure

Technical Field

The utility model relates to a structure is dismantled to flat head copper slider.

Background

The flat head of the work roll of the heavy and medium plate finishing mill consists of a flat head and a copper sliding plate, wherein the copper sliding plate is made of ZQA19-4, and the flat head is made of 34GrNi3 Mo. The rapid deformation and deterioration phenomena often occur under the conditions of frequent impact load, severe humid and dusty environment and large rolling force in the production process of the medium plate. In the rolling process, the torque at the connection part of the flat head and the universal shaft is larger, and a copper sliding plate in a flat head sleeve is abraded and deformed quickly, so that the gap between the small flat head and the roll head is increased, the roll system swings greatly, and the rolling precision is influenced, therefore, the sliding plate needs to be replaced when the sliding plate is seriously deformed and the size is out of tolerance. Meanwhile, the copper sliding plates are frequently replaced, and the sliding plates are difficult to replace and disassemble, so that a pair of copper sliding plates needs to be removed by the hairpin bit by bit, about 24 hours is needed, the labor intensity of workers is increased, the operation efficiency is low, and potential safety hazards exist.

Disclosure of Invention

An object of the utility model is to provide a structure is dismantled to flat head copper slider can dismantle copper slider fast conveniently, increases substantially work efficiency.

The structure is dismantled to flat head copper slider of realizing above-mentioned purpose, is equipped with the flat head of copper slider in including, is setting up two work holes along its radial coaxial line direction interval on the flat head, and the work hole that is close to flat head open end is the through-hole, and the work hole that is close to flat head exposed core is the blind hole, has inserted a round pin axle in through-hole and the blind hole respectively the cooperation, and the upper end of two round pin axles all is in the same place with a connecting plate rigid coupling.

During work, when the copper sliding block in the flat head needs to be disassembled, the copper sliding block can be slowly jacked down through the pin shaft arranged in the through hole only by smashing the connecting plate by using a hammer, and the pin shaft in the blind hole serves as a positioning pin. Through reforming transform slide structural style and little flat head body, reduce present 4 hours by a pair copper slide of dismouting before 24 hours, improved copper slide and changed efficiency to reduce intensity of labour.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic view of the structure of the present invention.

Detailed Description

The utility model provides a structure is dismantled to flat head copper slider, as shown in figure 1, is equipped with the flat head 5 of copper slider 3 in including, is setting up two work holes along its radial coaxial line direction interval on flat head 5, and the work hole that is close to the flat head open end is through-hole 2, and the work hole that is close to the flat head exposed core is blind hole 4, has inserted a round pin axle in through-hole 2 and the blind hole 4 cooperation respectively, and the upper end of two round pin axles all is in the same place with a connecting plate 1 rigid coupling. The pin shaft in the through hole 2 is a force application shaft, and the pin shaft in the blind hole 4 is a positioning shaft. When the copper sliding block 3 is used, the copper sliding block can be slowly jacked down by the pin shaft in the through hole 2 by knocking the connecting plate 1.

Claims

1. The utility model provides a structure is dismantled to flat head copper slider, is equipped with the flat head of copper slider in including, characterized by: two working holes are arranged on the flat head at intervals along the radial coaxial line direction of the flat head, the working hole close to the open end of the flat head is a through hole, the working hole close to the clamping end of the flat head is a blind hole, a pin shaft is respectively inserted in the through hole and the blind hole in a matched manner, and the upper ends of the two pin shafts are fixedly connected with a connecting plate.
