Abstract
The roll-pressing type quenching machine drainage roll comprises a roll body, a spiral line and a central lantern ring, wherein the roll body is in a circumferential shape, the roll body is made of stainless steel, two ends of the roll body are fixed by bearing seats, and a driving end is connected with a transmission gear; the spiral line is turned on the upper surface of the roller body, the direction of the spiral line reversely extends from the center of the roller body to two ends of the roller body, the outer diameters of the spiral line are positioned on the same horizontal plane, and the upper surface of the outer diameter is smooth and has no protrusion; the roll body mid-mounting central lantern ring, the central lantern ring adopts stainless steel semicircular structure to assemble and forms to fix convenient installation and demolish by the formula bolt of burying, the external diameter of central lantern ring is less than the external diameter of helix. The utility model improves the problem of uneven water discharge speed at the middle part and the two ends of the spiral roller in the quenching high-pressure cooling process, and can obviously reduce the control difficulty of the high-pressure cooling quenching plate type of the thin plate.
Description
Technical Field
The utility model belongs to the technical field of the metallurgy, a novel roll extrusion formula quenches quick-witted drainage roller is related to.
Background
In the production line of steel mill sheets, the drainage roller that roll-in formula quenching machine high pressure cooling device adopted mainly uses the screw-tupe drainage roller as the main, and the steel sheet is at quenching high pressure cooling in-process, and upper and lower spiral roller is used for retraining the deformation of steel sheet cooling process, and the spiral roller is derived high-pressure cooling water to the steel sheet both sides fast simultaneously to the inhomogeneous cooling of cooling water to the steel sheet surface after reducing the heat exchange. In the process of manufacturing the spiral drainage roller, a lathe turning tool turns from the middle of the roller way to two sides of the roller way, and a machining gap of the lathe turning tool is left at the initial machining position in the middle of the spiral roller. In the quenching high-pressure cooling process of the steel plate, the cooling speed of the turning tool gap in the middle of the spiral roller is different from the cooling speeds at two ends, so that the high-pressure quenching plate type control of the thin steel plate is extremely unstable, and the control of the quenching high-pressure cooling plate type of the high-quality ultrathin steel plate is a technical problem which always troubles the production line of the thin plate.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel roll extrusion formula quenches quick-witted drainage roller can improve the inhomogeneous problem of spiral roller middle part and both ends drainage speed among the quenching high-pressure cooling process to show the control degree of difficulty that reduces sheet metal high-pressure cooling quenching board type.
The purpose of the utility model is realized through the following technical scheme:
the roll-pressing type quenching machine drainage roll comprises a roll body, a spiral line and a central lantern ring, wherein the roll body is in a circumferential shape, the roll body is made of stainless steel, two ends of the roll body are fixed by bearing seats, and a driving end is connected with a transmission gear; the spiral line direction of the upper surface of the roller body extends reversely from the center of the roller body to two ends of the roller body, the outer diameters of the spiral lines are positioned on the same horizontal plane, and the upper surface of the outer diameter is smooth and has no protrusion; the middle part of the roller body is provided with a central lantern ring which is assembled by stainless steel semicircular structures and fixed by an embedded bolt, and the outer diameter of the central lantern ring is lower than that of the spiral line.
Drawings
Fig. 1 is a schematic structural view of a conventional spiral drainage roll.
Fig. 2 is a schematic structural view of the spiral drainage roller of the present invention.
Fig. 3 is a schematic cross-sectional view of the central sleeve ring of the spiral drainage roller of the present invention.
In the figure: the roller comprises a roller body 1, a spiral line 2, a bearing seat 3, a transmission gear 4 and a central lantern ring 5.
Detailed Description
The following describes the present invention with reference to the accompanying drawings and examples.
As shown in fig. 2, the base material of the roll body 1 of the roll-pressing type quenching machine drainage roll and the spiral drainage roll is made of stainless steel; turning the spiral line 2 by using a lathe from the central line of the roller body 1 as a processing starting point to two ends, wherein the rotating directions of the spiral lines 2 at the two ends of the central line of the roller body 1 are opposite, and the upper surface of the outer diameter of the spiral line 2 must be polished after the processing is finished, so that the outer diameter of the spiral line 2 is ensured to be in the same horizontal plane and smooth and flat; secondary cutting processing is carried out on the notch of the turning tool in the middle of the roller body 1, and the central lantern ring 5 is installed after the processed surface is smooth and flat; the central lantern ring 5 is formed by butt joint of semicircular stainless steel, and the fixed part is fixed by an embedded stainless steel bolt. And after the central lantern ring 5 is installed, polishing and grinding are carried out on the outer diameter surface of the central lantern ring, so that the outer diameter surface is smooth and flat. The outer diameter of the central collar 5 must be smaller than the outer diameter of the spiral wire 2.
Utility model drainage roller adopts the mode of integral erection and dismantlement, and the fixed bearing frame 3 at 1 both ends of roll body carries out off-line installation and precision adjustment, and novel drainage roller off-line is accomplished whole hoisting after installation and the precision adjustment and is transported to the machine that quenches, carries out the transmission with the drive gear 4 of the machine that quenches and is connected, lubricates the protection after drive gear 4 installs.
