CN102716920A - Automatic oil-removing and cleaning device for surfaces of tubes produced by cold tube mill - Google Patents

Abstract

When steel pipe enterprises are producing high-precision cold-rolled alloy seamless steel tubes, a large amount of rolling oil or saponified grease dirt is detained on surfaces of tube embryos after each time of cold rolling, which increases the difficulty of the next operation of pickling and oil removing and is prevented from discovering critical defects on the surfaces of the tube embryos timely and removing the defects immediately. The automatic oil-removing and cleaning device for the surfaces of tubes produced by a cold tube mil is suitable for the production of the high-precision cold-rolled alloy seamless steel tubes. By utilizing self rotary and forward composite motions (without need for extra forces) during embryo rolling, the device performs oil removing and cleaning automatically through oil-removing plugging sheets of double-layered oil-proof rubber and cleaning plugging sheets of double-layered thickened wool felt. The device has simple structure, good generality, beautiful appearance and small size.

Description

The automatic oil removing cleaning device of cold pilger mill tube-surface

[0001]?

In the cold pilger mill series, can slightly divide two types, three kinds of specifications at present:

A type (producing) Type B (producing) with saponified oil with ROLLING OIL

Three kinds of specifications:

Large size specification-two roller LG80, two roller LG110H, two roller SKW75 etc.

Medium size specification-two roller KPW50, two roller X π T55, two roller LG60H, three roller LD60 etc.

Small size specification-two roller LG30H, three roller LD30 etc.

This device, two interchangeable targeting ports of every kind of specification configuration size

Illustrate:

If the pipe of the rolling 38X2 of supplied materials 57X4, and select the A type and the Type B device of medium size specification to deduce.

At first screw in little targeting port to device

A type-, carry out the secondary oil removing through double-deck oil resistant rubber oil removing inserted sheet earlier when the 38X2 pipe that rolls out is rotating access to plant.

Oil removing for the first time, greasy dirt is collected through the hole of letting out of leaking interbed inflow bottom, and oil removing for the second time remains the seepage floor of greasy dirt through 5 mm wides on a small quantity, and the entering bottom is let out the hole and is collected.Pipe continues to get into double-deck wool felt cleaning inserted sheet, carries out the secondary cleaning.

Clean for the first time tube-surface, another lets out hole eliminating collection through bottom of device to remove thing, and when cleaning tube-surface for the second time, still a small amount of removing thing of stream sees through the seepage floor inflow equally and lets out the hole collection.

Type B-when producing with saponified oil, a notable feature is arranged, the greasy dirt dirt is adhering to tube-surface, is difficult to remove these greasy dirts with the rubber ring inserted sheet and must uses the method processing that the wire loop inserted sheet adds the moist scouring of cleaning fluid instead.

So, install a rubber water proof circle inserted sheet additional at the device portal place, and first lets out the hole bottom the handle assembly, moves on to the middle part, both sides, expands into key shape hole, at the device top circulating cleaning fluid shower nozzle is installed again, keep certain liquid.

Treat to get into wool felt cleaning inserted sheet again after the pipe removing grease.

The pipe that process A type or Type B device come out, the surface is as neat as wax, can immediately find the tube-surface defective, removes.

Inside pipe wall leaves a little greasy dirt like this, has improved the pickling quality of deoiling.Both reduce the discharging of spent acid, improved production environment again.

In addition, this device is regulated the miscellaneous function of rolling centerline in addition, makes cold pilger mill be in the as-rolled condition an of the best all the time.

Claims (6)

1. " the automatic oil removing cleaning device of tube-surface ", according to cold rolled tube rolling in self rotation and advance the compound motion characteristics and design.Can reach automatic oil removing, the requirement of cleaning tube-surface.

2. this device divides A type (producing with ROLLING OIL), Type B (with the old explained hereafter of saponified oil).

3. every kind of specification of this device disposes two interchangeable targeting ports of size.

4. illustrate:

If the A type and the Type B device of the pipe of the rolling 38X2 of supplied materials 57X4

and selection medium size specification are deduced.

At first screw in little targeting port to device

A type-, carry out the secondary oil removing through double-deck oil resistant rubber oil removing inserted sheet earlier when the 38X2 pipe that rolls out is rotating access to plant.

Oil removing for the first time, greasy dirt is collected through the hole of letting out of leaking interbed inflow bottom, and oil removing for the second time remains the seepage floor of greasy dirt through 5 mm wides on a small quantity, and the entering bottom is let out the hole and is collected.Pipe continues to get into double-deck wool felt cleaning inserted sheet, carries out the cleaning second time.

Clean for the first time tube-surface, another lets out hole eliminating collection through bottom of device to remove thing, and when cleaning tube-surface for the second time, still a small amount of removing thing of stream sees through the seepage floor inflow equally and lets out the hole collection.

Type B-when saponified oil is produced, a notable feature is arranged, the greasy dirt dirt is adhering to tube-surface, is difficult to remove these greasy dirts with the rubber ring inserted sheet and must uses the method processing that the wire loop inserted sheet adds the moist scouring of cleaning fluid instead.

So, install a rubber water proof circle inserted sheet additional at the device portal place, and first lets out the hole bottom the handle assembly, move on to middle position, both sides, expand into key shape hole, at the device top circulating cleaning fluid shower nozzle is installed again, keep certain liquid.

Treat to get into wool felt cleaning inserted sheet again after pipe the removing grease.

Pipe surface that process A type and Type B device come out is as neat as wax; Can immediately find the tube-surface defective, remove.

Inside pipe wall leaves a little greasy dirt like this, has improved the pickling quality of deoiling.Both reduce the discharging of spent acid, improved production environment again.

In addition, this device is regulated the miscellaneous function of rolling centerline in addition, makes cold pilger mill be in the as-rolled condition an of the best all the time.

5. the aperture of " oil removing inserted sheet " and " cleaning inserted sheet " and ring-like pass or roll are complementary.

6. Fig. 1 is the oil removing of steel tube surface, the cleaning device stereogram.

Fig. 2 is that the device that is applicable to the LG60H pipe mill is led a mouthful figure

Fig. 3 is the fundamental diagram of the automatic oil removing cleaning device of cold pilger mill tube-surface

Fig. 4 is A type A-A profile and B-B profile (bottom)
