Abstract
The present invention relates to a hot pressing restoring method for corrugated rollers, which is suitable for the restoration of a corrugated roller as a key part of a corrugated paper board machine. The method comprises the steps that the edge teeth of a corrugated roller are removed; after being reduced, an outer circle is sheathed on a metal material used for compensation and has a hardened surface to be used as a sleeve in a subsection mode, and a heating sleeve is arranged on a roller body by adopting interference fit; finally, the corrugated roller is reprocessed to reach the original technical requirements of the corrugated roller. The present invention is used for restoring corrugated rollers to make the corrugated rollers regenerated, the regeneration of the corrugated roller can be repeatedly carried out, so a large quantity of raw materials can be saved, and the present invention has favorable economic benefit.
Description
Invention field
Use is produced in the regeneration that the present invention relates to the corrugation roller.Exactly, the present invention relates to the hot pressing recovery technique of corrugation roller.
Prior art
Traditional corrugation roller great majority are all-in-one-piece, and its common length is 1200 millimeters-2700 millimeters and directly makes stupefied tooth on the plain roller body.Behind predetermined extent, whole corrugation roller has just been scrapped at the stupefied odontotripsis of this corrugation roller.This has caused great waste of material.U.S. Lord Lansdowne company had once proposed a kind of like this corrugation roller, promptly adopted hot pressing cover mode to form discaling roll on the lower roll of a pair of corrugation roller.The top roll of described corrugation roller remains a monoblock type corrugation roller.Such lower gear roller is a new system corrugation roller.Its effect is to utilize the passage that the formed inner chamber conduct of equally distributed groove is bled on roller shell and the outer garden of mandrel, adsorbs corrugated paper.Such corrugation roller does not relate to the method that the waste and old corrugation roller of original monoblock type is repaired into new corrugation roller at all.
Goal of the invention
The objective of the invention is a kind of corrugation roller hot pressing restorative procedure will be provided so that the problem that the stupefied odontotripsis of monoblock type corrugation roller that exists in the solution prior art is scrapped with regard to integral body.
Technical scheme
For realizing above-mentioned purpose, at this a kind of corrugation roller hot pressing restorative procedure has been proposed, it may further comprise the steps: a) cut away the stupefied tooth of a pair of reparation corrugation roller and form a pair of plain roller body; B) but make the roller shell of 40 millimeters-300 millimeters long with the hard facing metal material, after having heated described roller shell, utilize interference fit with described roller shell segmented sheathing on described roll body; C) process stupefied tooth again and make it reach the original specification requirement of corrugation roller.
Specification requirement
Can adopt corrugation roller hot pressing recovery technique of the present invention to repair the old corrugation roller of existing monoblock type, make it regeneration and can repair (changing roller shell gets final product) repeatedly, thereby can save a large amount of raw material and corrugation roller acquisition cost.Therefore, this corrugation roller recovery technique has favorable economic benefit.
The embodiment explanation
The present invention relates to the vital part of corrugating machine---the reparation using method of corrugation roller.This method is performed such: at first, the stupefied tooth of a pair of old corrugation roller is cut away and form a pair of plain roller body, then, with the roller shell of can case-hardened metal material making 40 millimeters-300 millimeters long, wherein the roughness Ra of faying face equals 1.6 microns, subsequently, roller shell is placed on is heated to 300 ℃ and select DH for use in the oil groove
7/ u
6Interference fit on above-mentioned roll body, is processed described roller shell segmented sheathing again stupefied tooth at last and is made it reach the original specification requirement of corrugation roller.
Claims (1)
1. corrugation roller hot pressing restorative procedure, it may further comprise the steps:
A) cutting away a pair of need repairs the stupefied tooth of corrugation roller and has formed a pair of plain roller body;
B) but the roller shell of making 40 millimeters-300 millimeters long with the hard facing metal material behind the described roller shell of heating, utilize interference fit with described roller shell segmented sheathing on described roll body;
C) process stupefied tooth again and make it reach the original specification requirement of corrugation roller.
