    [19] The present invention also provides a shape memory injection and expansion method using a shape memory injection and expansion system, comprising: preparing a unit tube cut to a predetermined length in a process line; Moving the unit tube prepared on the process line to precipitate in a shape memory injection container filled with glycra solution, and performing shape memory injection treatment according to temperature and time variation; Removing the shape-memory unit tube from the shape memory injection container, and moving to the expansion device using a transfer device to expand the shape-measuring unit in a shape memory manner; Cutting the expanded unit expansion into the predetermined size in the expansion unit; Trimming both ends of the cut dilated tube; And it can be achieved by the shape memory injection and expansion method characterized in that it comprises the step of wrapping the finished expansion pipe.
    [20] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
    [21] In Figure 1, the shape memory injection and expansion system of the unit pipe according to the present invention and the method is carried out in a series of process lines, first formed of a synthetic resin such as plastic unit tube 10 cut to a certain length On the process line 12 installed on the factory floor, the crane 14 is lifted and precipitated in the shape memory injection container 16 filled with glycacrol (glyacrol) liquid, and the temperature is changed for a predetermined temperature and time. Glyacrol solution can be purchased from Selling Plast, Denmark.
    [22] In order to enlarge the diameter of the unit pipe 10, the transfer pipe 18 is moved to the expansion pipe 20 to be loaded. Expansion device 20 is a main body 22 for loading the unit pipe 10 and the expansion frame (arbor) that can be inserted into the stacked unit pipe 10 to perform actual expansion and have a variety of diameters and shapes (24), a press (26) for applying pressure to the expansion frame (24), and a cooling device (28) for immobilizing heat and shape memory generated during expansion. Here, the unit pipe is expanded in a state where the shape before expansion is stored.
    [23] On the other hand, it is preferable that the process line 12 in which the expansion device 20 is installed is provided with a drain line 12a for discharging the cooling water discharged from the expansion device 20 to the outside or sending it to the reprocessing facility.
    [24] The unit expansion pipe 10a expanded in the shape memory state from the expansion device 20 is then transferred to the cutting device 30 and cut into a predetermined size.
    [25] In order to finish the expansion pipe 10a 'cut in predetermined units, it is transferred to the beveling device 32 and loaded, and both ends of the expansion pipe 10a', that is, the copper parts are trimmed.
    [26] Thereafter, it is transferred to the packing table 34 and arranged to wrap the final expanded tube 10a '. The packing table 34 indexes the size, lot number, production date, etc. of the expansion pipe 10a, wraps it with wrapping paper, fixes and finishes it with tape, and supplies it to the supplier or the recipient.
    [27] As described above, the embodiment of the expansion method in more detail as follows.
    [28] The glyacrol solution filled in the shape memory injection container 16 for the shape memory injection is, for example, a shape memory at a predetermined time and temperature using a glyacrol solution manufactured by Selling Prist in Denmark. Inject.
    [29] For example, the amount of glyacrol maintains a depth at which the unit tube can be immersed by about 1000 mm, and when the production operation is not performed, the lid of the container is covered to prevent the temperature from dropping or the entry of foreign substances, for example, a shape memory injection container ( Check the temperature of 16) by checking the set temperature of the temperature controller attached to it and the temperature of the upper part of the solution by digital thermometer every 2 hours. Check each time immediately before and during work for 4 hours. In addition, the specific gravity of the gliacro solution is checked by using a hydrometer every two hours to maintain the specific gravity according to the established production management regulations.
    [30] On the other hand, set the expansion frame of the size to be produced. Thereafter, the air inlet pipe (2) and the coolant inlet tube of the press are connected to the expansion frame by using a one-touch nipple, and then the air inlet switch and the coolant discharge switch of the cooling device 28 are operated to connect the one-touch nipple. Check.
    [31] After checking and checking various pressures such as hydraulic press, air compressor, water pump, etc., the amount of coolant discharge is controlled by the switch under the coolant injection pressure gauge, and the cooling time is set by production management regulations.
    [32] On the other hand, in the lower end of the unit pipe 10, for example, the display is indexed primarily at about 1000 mm, and is prepared near the shape memory injection container. Thereafter, the unit pipe 10 is lifted using the crane 14 to gradually lock the unit tube 10 into the shape memory injection container 16 to sufficiently lock to the first marked position, thereby performing shape memory injection processing for shape memory for a predetermined time. . Subsequently, by moving to the expansion device 20 and placing it on the expansion mold 24 using the press 26 and pressing to execute the primary expansion, the surface and the inner surface with the cooling water for a predetermined time using the cooling device 28. Cooled to fix the stored shape. After that, the first expanded pipe 10 is separated from the expansion frame 24 for the second expansion, and then turned upside down so as to be in the direction of expansion (upper end) at a boundary line position between the expanded and unexpanded parts. After marking the secondary at the position, the shape memory injecting container 16 is again provided as described above.
    [33] The secondary display is sufficiently immersed to the indexed position, and the shape memory processing using the temperature variation is again performed for the shape memory for a predetermined time.
    [34] Thereafter, the unit tube 10 is pushed into the expansion frame so as to be positioned at the center of the press plate at the top of the press. Thereafter, the press is operated to push down the plate at the upper end to compress the upper end of the unit tube, thereby expanding the tube to the marked position. Thereafter, the cooling water discharge switch is operated to cool the inside and the outside of the unit tube until the set time to fix the stored shape.
    [35] Thereafter, after the coolant discharge switch is operated, the operation of the press is stopped to prevent aging and noise of the hydraulic press.
    [36] When the expansion of the expansion pipe is completed, the press arm is operated to remove the shape memorized expansion pipe and fitted into the release plate of the expansion frame. Operate the press in reverse to disengage the expansion tube from the expansion frame. When the lower part of the expansion plate of the expansion pipe reaches the predetermined position of the expansion frame, use the left hand to push the lower part of the release plate to fix it and prevent the press plate from falling down. The press arm, which extends down from 100mm to 200mm, hangs on both sides of the release ring, is removed from the loop of the release plate, and the release plate of the expansion frame is returned to the lower end of the expansion frame.
    [37] The press plate is positioned to the end of the press upper end, so as not to be disturbed during the second expansion, and the expanded unit pipe is pulled out from the press using the handle of the transport frame to facilitate the escape of the expansion pipe from the expansion frame.
    [38] After that, take out the first expansion pipe by using the moving lever, turn it over, mark the second one, and then work in the same way.When the expansion of the second pipe is completed, the length of the expansion pipe whose shape memory is completed is about 1450 mm (allowed car -20 mm). Becomes In addition, the foreign matter on the surface of the produced expansion pipe and the surface of the exterior is washed with ground water, and then introduced into a subsequent process.
    [39] Subsequently, rejected products that are recognized as having an impact on the quality of the product must be marked and stored separately so that they can not be put into the production process, and should be kept for future experiments or disposal. Process checklists are used by production personnel to record and keep the results of time-of-day or occasional checks and actions, and to manage the lot for the finished product.
    [40] As a result, the present invention heats a certain temperature to the heat shrink casing (MS-JOINT) product produced by the shape memory injection to return to the size of the expansion before the expansion, that is, the size of the stored shape to secure the neighboring connector It is easy to make uniformity of product quality, manufacturing and production management by improved technology effect, expansion system and expansion method that can be crimped, and it can be expanded simultaneously with manufacturing in the line that is addressed to the manufacturing line of shape memory tube. There is an effect to be improved.
    [41] Although a preferred embodiment according to the present invention has been described above, it will be understood by those skilled in the art that various modifications and changes can be made without departing from the scope of the appended claims.
