Abstract

The utility model discloses a piston rod with a replaceable roller bending cylinder, which is mainly formed through connecting and assembling a piston rod body with a plug through a screw. The piston rod has the advantages of reasonable design, simple manufacturing, convenient detachment, reduced auxiliary member of device, reduced stoppage time in replacing the piston rod, and reduced manufacturing cost.

Description

A kind of roller cylinder Changable type piston rod
Affiliated technical field
The utility model relates to a kind of piston rod, and particularly a kind of roller cylinder Changable type piston rod is applicable to metallurgical equipment six-high cluster mill work roll bending cylinder.
Background technique
At present, metallurgical equipment six-high cluster mill work roll bending cylinder cylinder bar is an integral type, in actual use; cylinder bar front end screw thread goes out and can rupture, and needs to change again piston rod after the fracture and could continue to use, because this position complex structure; dismounting inconvenience, dead time is long.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of roller cylinder Changable type piston rod is provided.This is not only reasonable in design, makes simply, and convenient disassembly, the dead time when having reduced the acknowledgment copy of equipment and having changed piston rod, reduced cost of production.
The technical solution adopted in the utility model is: the piston rod body assembles by screw rod and top and constitutes.Earlier process a screw at piston rod body front end, reprocessing a screw rod is screwed on the piston rod body, the top is connected with the piston rod body by screw rod, during use, after screw rod ruptures, the residue screw rod that only needs to remain in piston rod body front end is back-outed, and changes a screw rod again and gets final product, and has avoided taking place the inconvenience of fracture back integral replacing.
The beneficial effects of the utility model are that simple in structure, easy to use, after screw rod ruptured, the residue screw rod that only needs to remain in the piston rod front end was back-outed, and changes a screw rod again and gets final product, and had avoided taking place the inconvenience of fracture back integral replacing.Because this position complex structure, dismounting inconvenience has reduced the dead time when changing piston rod, has reduced the spare part and the cost of production of equipment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Accompanying drawing number is: 1. piston rod body, 2. screw rod, 3. top.
Embodiment
With reference to Fig. 1, piston rod body (1) assembles with top (3) by screw rod (2) and constitutes.Earlier process a screw at piston rod body (1) front end, reprocessing a screw rod (2) is screwed on the piston rod body (1), top (3) is connected with piston rod body (1) by screw rod (2), during use, after screw rod (2) ruptures, the residue screw rod (2) that only needs to remain in piston rod body (1) front end is back-outed, and changes a screw rod again and gets final product, and has avoided taking place the inconvenience of fracture back integral replacing.
