Abstract
An automatic screwed pressing method is adopted for the middle diameter-reduction shaping of a pipe material of zirconium alloy in the past; the screwed pressing method has the disadvantages of high cost and strong technicality. The present invention relates to a combined mould shaping method, which adopts a processing mode of replacing a roller by the self rotation of profiling ball bearings; the profiling ball bearings are distributed in the circumferential direction, the reinforcing function of a supporting core rod is replaced, and process steps are simplified. The method of the present invention has the advantages of small volume, low manufacture cost, no need of special-purpose equipment or special-purpose technique, realization of bulk production without the supporting of the core rod, and high rate of finished products; the combined mould shaping method not only can be used for shaping a diameter-reduction pipe, but also can be used for processing metal pipe materials and shaping special-shaped pipe materials.
Description
The present invention is the assembling die of used in nuclear power station zircaloy reducing guide pipe moulding.
The undergauge moulding of zirconium alloy tube, the past all is to adopt the automatic spinning method.The High Precision Automatic imitative type spinning machine of general employing cooperates the special core bar machine-shaping of high accuracy.This special equipment is once invested greatly, and is technical strong.
For overcoming above-mentioned shortcoming, be thin-walled, the small dimension reducer pipe of producing certain batch, the present invention adopts the assembling die moulding.Adopt the processing mode of the rotation replacement spinning roller of imitative type ball, imitative type pearl frame will be imitated the type ball by circumferential distribution, solve the circumferentially even stress deformation of tubing, the booster action that has replaced supporting core rod, simplified operation, assembling die of the present invention has that volume is little, cost is low, does not need special equipment, does not need core bar to support, and can produce in batches, and production technology is easy to grasp and the yield rate height.Assembling die moulding of the present invention except that the moulding that is used for reducing guide pipe, also can be used for the processing of metal pipe material, the reducer pipe of different reducings and the moulding of shape tube, and the scope of application is extensive.
The structure of assembling die such as accompanying drawing: by master form cover (1), bearing gland (2), bearing (3), die coat (4), master form (5), imitative type ball (6), imitative type pearl frame (7), bearing (8), bearing holder (housing, cover) (9), thread (10), end cap (11), and rotation hand wheel (12) constitute.Master form cover (1) is that the hole axle cooperates with bearing (3), bearing gland (2) is general being threaded with die coat (4), imitative type ball (6) is a loose fit with imitative type pearl frame (7), imitative type pearl frame (7) is that the hole axle cooperates with bearing (8), bearing (8) is an interference fits with bearing holder (housing, cover) (9), bearing holder (housing, cover) (9) is to be threaded with thread (10), and end cap (11) is to be threaded with die coat (4), and rotation hand wheel (12) is a loose fit with end cap (11).
The forming principle of assembling die is: the circumferential rotation by imitative type ball (6) and vertically moving, press the track of master form (5), and by putting line,, finish the moulding of undergauge section by the moulding track of line to face.The forming method of assembling die: adopt rotation (or fixing) formula master form (5) and rotating imitative type pearl frame (7) to match, utilize be threaded (or hydraulic drive) to advance thread mechanism (10) molding necked section.
Another kind of molding mode is that assembling die is fixed on the knife rest, utilizes the rotation and the self-acting feed of pipe, molding necked section of mobile assembling die.
Assembling die when the reducer pipe of different reducings and the moulding of special section tubular product, only needs to change corresponding master form tool and different imitative type pearl framves and relative measures in the processing that is applied to the metal material, just can use.
The process of the molding necked guide pipe of assembling die:
With centre frame assembling die is fixed on the lathe, one termination is fixed on the chuck, the characteristics of utilizing imitative type ball (6) to go up or move radially at imitative type pearl frame (7), with pipe by behind the assembling die, tubing one end is fixed on the jig of knife rest, utilize the lathe rotation to drive the pipe rotation or drive master form (5) and rotate, utilize master form (5) to add to the power of imitative type ball (6) and the reaction that tubing is given imitative type ball (6), rotation by imitative type pearl frame (7), imitative type ball (6) is caused by the machining deformation of putting line tube surfaces, by thread mechanism (10) imitative type pearl frame (7) is moved, imitative type ball (6) is moved along the track of master form (5) is spiral, cause tubing by the distortion of line to face, by the imitative position display of type ball (6) in master form (5), utilizing screw thread to block the bar propulsive mechanism divides secondary to finish the moulding of two ends undergauge changeover portion, the machine-shaping of undergauge section, adopt from the mode moulding of walking moving knife, the size of undergauge section is guaranteed by master form (5).
Claims (1)
1, a kind of assembling die that is used for the reducing guide pipe moulding, assembling die are to be made of master form (5), master form cover (1), imitative type ball (6), imitative type pearl frame (7), bearing (3,8), bearing gland (2), bearing holder (housing, cover) (9), thread (10) end cap (11), die coat (4), rotation hand wheel (12).It is characterized in that master form cover (1) and bearing (3) are that the hole axle cooperates, bearing gland (2) is general being threaded with die coat (4), imitative type ball (6) is a loose fit with imitative type pearl frame (7), imitative type pearl frame (7) is that the hole axle cooperates with bearing (8), bearing (8) is an interference fits with bearing holder (housing, cover) (9), bearing holder (housing, cover) (9) is to be threaded with thread (10), and end cap (11) is to be threaded with die coat (4), and rotation hand wheel (12) is a loose fit with end cap (11).
