Abstract
The present invention relates to a calendering roller of a papermaking calendering machine, which is composed of a roller sleeve and a roller shaft, wherein the roller sleeve and the roller shaft are combined into the calendering roller in the heat assembly mode of in the screw bolt connection mode. The present invention has the advantages of improving the quality of products and lightening self-weight, and solves the problem that the upper roller neck of the integral casting calendering roller is loose.
Description
Technical field
The present invention relates to a kind of roll presses for paper industry felt wrapped roll, particularly a kind of cast iron felt wrapped roll is mainly used in the cast iron felt wrapped roll of hard calender, supercalender, gloss calender and the soft press-polishing machine of paper industry.
Background technology
In the modern paper industry, the page that various paper machine makings go out all needs to carry out press polish via calender, and to improve glossiness, tightness and the thickness evenness of page, felt wrapped roll plays key effect to the quality of page.
In the prior art, felt wrapped roll is to produce with the single static casting of alloy chilled cast iron quality (vertical gravity-assist pouring) process, and product is a mono-material unitary solid cast iron roll.Product quality exists two large problems to be difficult to solve: 1, there are casting flaws such as pore, sand holes in body surface.2, because the felt wrapped roll shape is elongated, be difficult for feeding in the last roll neck process of setting, be difficult to avoid loose phenomenon, not wear-resisting in the use with the bearing shell contact site, be easy to damage.
Summary of the invention
The purpose of this invention is to provide a kind of combined calender roll for papermaking calender, both improved the roll surface quality, can eliminate the loose phenomenon of roll neck again fully.
For achieving the above object, technical scheme of the present invention is: a kind of combined calender roll for papermaking calender, and it is assembled by roller shell 1 and roll shaft 2 two parts of two materials, has following characteristics and advantage:
1. roller shell is made of the inside and outside two-layer of unlike material, produces by the centrifugal composite casting process.Be used as the centrifugal casting under 40～120 times gravity coefficient of outer field liquid metal, and quicken cooling with metal mold, outer layer metal solidifies the back even compact, can eliminate casting flaws such as pore, sand holes.Significantly improve the roll surface quality.Skin is poured into a mould inner layer metal after solidifying and finishing, and the two metallurgy is fused into one, and internal layer provides the supporting of an obdurability for skin at once.
2. roller shell 1 adopts hot charging mode or bolted on connection mode to be grouped together with roll shaft 2 two parts.Roll shaft is casting or forging production separately, can eliminate rarefaction defect fully, guarantees that roll shaft upper bearing (metal) position has good ABRASION RESISTANCE.
3. combined type felt wrapped roll roller shell inside is cavity, has alleviated roll body weight, saves metal material.
Description of drawings
Fig. 1 is the structural representation that adopts the combined type felt wrapped roll that the hot charging mode assembles;
Fig. 2 is the structural representation that adopts the combined type felt wrapped roll of bolt 3 bind modes assembling.
The specific embodiment
Fig. 1 is the combined type felt wrapped roll that adopts the hot charging mode to assemble, and relies on the magnitude of interference with roller shell 1 and roll shaft 2 mounts, bears operating pressure.
Fig. 2 is the combined type felt wrapped roll that adopts the assembling of bolt 3 bind modes, and screwed hole is arranged on the inner layer metal position of roller shell, is convenient to processing.
The various casting flaws of body of roll roll neck have been eliminated fully by the combined calender roll for papermaking calender of technique scheme production, significantly improved the felt wrapped roll quality, particularly long (felt wrapped roll of 2000mm～10000mm), combined type felt wrapped roll of the present invention more demonstrates huge superiority for using more roll surface in recent years.
Claims (2)
1. combined calender roll for papermaking calender, it is characterized in that: it is made up of two material roller shells (1) and roll shaft (2) two parts, the two machinery is assembled into the combined type felt wrapped roll, and wherein roller shell (1) is fused into one by the outer two kinds of materials of internal layer with high tenacity of high-wearing feature by centrifugal composite casting process metallurgy.
