Abstract
The utility model discloses a roller of a roll die of a steel cylinder drawing machine. The roller comprises a shaft and an annular roller sheathed on the shaft, wherein the shaft and the annular roller are connected through a plurality of rolling bearings distributed abreast. The shaft of the roller and the annular roller are connected through the rolling bearings to generate rolling friction and ensure that the wheel face does not deflect when the annular roller rolls, thus ensuring the effect of calendering a bottle body by the roll die. Simultaneously, the rolling friction is not likely to abrade the bearings that does not need replacing regularly, thus prolonging the service life of the roller.
Description
Technical field
The utility model relates to steel cylinder manufacturing technology field, relates in particular to the roller of the rolling mould of steel cylinder pulling machine.
Background technology
At present, domestic major diameter steel cylinder all is that the method manufacturing of adopting seamless steel pipe to receive the end, closing in forms, and the steel cylinder specification of this method manufacturing and wall thickness are limited by employed steel pipe all, and adopt process for stamping can obtain the steel cylinder of various diameters and wall thickness easily.
Pressing is made steel cylinder and is generally comprised operations such as the vertical punching press of material base, pulling bottle base, closing in.The used pulling machine of pulling bottle base is made up of reciprocating tringle and the ring mould and the rolling mould that are located along the same line, during the bottle base pulling, tringle one end pushes the bottle base intracavity bottom, makes bottle base pass ring mould and rolling mould successively, with the bottle pulling, correspondingly the attenuation of bottle wall becomes light.
Rolling mould in the pulling machine is made up of the mould bases of annular and 4 rollers being evenly distributed on the mould bases inboard, the wheel shaft of roller is horizontally disposed with, two ends are fixed on the mould bases, and the wheel face of 4 rollers is the circular arc concave surface, and the wheel face of these 4 rollers surrounds a circular hole that supplies bottle base to pass through.
Existing roller normally is made up of axle, bearing shell and scroll wheel, connects by bearing shell between axle and the scroll wheel.During roller work, produce sliding friction between bearing shell and the axle, and produce very high temperature, make bearing shell, need frequently bearing shell to be changed easily because load is excessive, temperature is crossed high factor and caused bearing bush abrasion; In addition,, thereby make roller swing and occur departing from, thereby influence the effect of rolling mould calendering bottle wall because the sliding friction between bearing shell and the axle is easy to generate the gap.
Summary of the invention
The utility model provides a kind of roller of rolling mould of steel cylinder pulling machine, and roller used bearing shell to cause roller deviation affects calendering effect and wearing and tearing to cause the frequent problem of changing of rotor block easily when this roller had solved existing rolling mould calendering bottle wall.
A kind of roller of rolling mould of steel cylinder pulling machine comprises axle and the annular scroll wheel that is enclosed within on the axle, connects by several rolling bearings that distribute side by side between described axle and the annular scroll wheel.
In the optimized technical scheme, the quantity of described rolling bearing is 4.
In the optimized technical scheme, the two ends of described annular scroll wheel are provided with cover plate, prevent that foreign matter from entering the damage rolling bearing.Can also between cover plate and rolling bearing, packing ring be set, reducing the friction between cover plate and the rolling bearing, and play the effect of sealing.
Rolling element in the rolling bearing is cylindrical, can bear bigger pressure.
The wheel face of roller of the present utility model is the circular arc concave surface, several above roller set is attached together on the rolling mould mould bases that is fitted on the pulling machine form rolling mould, and the wheel face of roller surrounds a circular hole that supplies bottle base to pass through, so that the bottle outer surface rounding off of calendering.
Connect by rolling bearing between the axle of roller of the present utility model and the annular scroll wheel, produce rolling friction, guarantee that annular scroll wheel wheel face when rolling does not depart from, thereby guaranteed the effect of rolling mould calendering bottle; Simultaneously, rolling friction is difficult for running out bearing, and does not need frequent replacing, thereby has prolonged the service life of roller.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model roller.
The specific embodiment
As shown in Figure 1, a kind of roller of rolling mould of steel cylinder pulling machine comprises axle 1 and the annular scroll wheel 2 that is enclosed within on the axle 1, passes through 3 connections of 4 rolling bearings that distribute side by side between described axle 1 and the annular scroll wheel 2.
The two ends of annular scroll wheel 2 are provided with cover plate 4, prevent from that foreign matter from entering rolling bearing 3 is damaged.Cover plate 4 is fixed by several nuts.
Also be provided with packing ring 5 between cover plate 4 and the rolling bearing 3, reducing the friction between cover plate 4 and the rolling bearing 3, and play the effect of sealing.
Rolling element in the rolling bearing 3 is cylindrical, can bear bigger pressure.
The wheel face of roller is the circular arc concave surface, 4 above-mentioned roller set are attached together on the rolling mould mould bases that is fitted on the pulling machine form rolling mould, the wheel face of roller surrounds a circular hole that supplies bottle base to pass through, bottle base passes therethrough, owing to connect the generation rolling friction by rolling bearing 3 between axle 1 and the annular scroll wheel 2, guarantee that annular scroll wheel wheel face when rolling does not depart from, thereby guaranteed to obtain the bottle outer surface rounding off of calendering.
Claims (4)
1. the roller of the rolling mould of a steel cylinder pulling machine comprises axle and the annular scroll wheel that is enclosed within on the axle, it is characterized in that: connect by several rolling bearings that distribute side by side between described axle and the annular scroll wheel.
2. roller according to claim 1 is characterized in that: the quantity of described rolling bearing is 4.
