Description
Technical field
The present invention relates to a kind of expander apparatus for shaping for small internal diameter thick walled steel tube.
Background technology
Compressor case is motor in compressor and the important supporting member of some parts, it is desirable to which cylinder has preferable circle
Degree, cylindricity and internal diameter size.Existing housing can have to the circularity of workpiece after welding to be welded into a cylinder after steel plate roll bending
Very big influence, it is therefore desirable to which the cylinder welded is placed in an expanding die, to obtain preferable circularity and size needs.
As shown in Figure 1-2, cylinder is on pipe expander, and the profile of mandrel 1 is tool for the expander apparatus for shaping of existing cylinder
There are eight faceted pebbles of constant slope, mandrel and hydraulic press（Not shown in figure）Oil cylinder in piston 6 be connected, the descending band of piston 6
Moving mandrel 1 is descending together.Eight activities with gradient are risen by block 2 radially by eight faceted pebbles of mandrel 1 during descending
Expand, the purpose for expanding internal diameter and shaping is reached with this.But the expander mode of this drop-down mandrel, it is only applicable to Steel Thin-Wall
Pipe.
In addition, patent document（Publication No. CN201969786U）A kind of Intermeshing type accurate pipe-expanding die is disclosed, its expander
Mode be above to push away or pull down at push rod by hydraulic press, the up and down motion of mandrel is caused, so that fan-shaped wedge is outward
Expansion.Similarly, this expander mode for above pushing away or pulling down mandrel, is only applicable to thin-wall steel tube.
And be the small internal diameter cylinder of heavy wall using the housing of carbon dioxide as the compressor of cooling medium, its wall thickness can reach
6.5mm, the stress needed for its expander is very big.If expander, above-mentioned drop-down are carried out to thick walled steel tube using existing pipe expander
The expander mode of mandrel, mandrel is easy to be pulled off.Again due to pipe diameter it is smaller, outside diameter of mandrel also therefore be restricted without
Can overstriking.
For above-mentioned technical problem, existing solution is the pulling force allowable for first calculating mandrel, then adjusts hydraulic pressure
Oil pressure, control enters the oil mass of oil cylinder, the lower pulling force of piston is less than the pulling force allowable of mandrel.Such method, is typically needed
2 ~ 3 expander shapings are wanted to can be only achieved required internal diameter size.And do not have after an expander, also cylinder is heat-treated.
Obviously, such method can reduce low production efficiency, increase production cost.

Motion upwards；Controller, the lathe sliding block（80）, the hydraulic control device be connected with the controller, by the control
Device control processed.
Further, the activity is risen block（20）Some is along the circumferential direction divided into, various pieces are in from the side
Zigzag.
Further, the controller controls the briquetting simultaneously（80）With the oil cylinder piston（60）Work, the pressure
Block（80）To mandrel（10）Lower pressure and oil cylinder piston（60）To mandrel（10）Lower pulling force adjusted by the controller.
Additionally, it is provided a kind of compressor housing, the housing is by the above-mentioned expander apparatus for shaping for small internal diameter thick walled steel tube
Obtained after expander shaping.
The beneficial effects of the invention are as follows：In the case where not increasing mandrel size and being changed without mandrel material, in expander
Mandrel will not be broken in reforming process, can be and simple in construction to a small expander shaping of internal diameter thick walled steel tube, be improved
Production efficiency.
