Detailed Description
A manufacturing process of a high-strength PVC pipe fitting comprises the following steps
The method comprises the following steps: preparing materials required by the PVC pipe fitting according to various raw materials;
step two: the material which can be used for preparing the PVC pipe fitting is flushed into a die to be cooled and molded;
step three: polishing and punching the formed PVC pipe;
in addition, as an example, as shown in fig. 3, this example solves the problem of separately supporting the weak portion of the PVC pipe to prevent damage caused by processing,
because fixedly connected with lock ring 301 on first pneumatic cylinder 203, add man-hour to the PVC pipe fitting, the staff can control first pneumatic cylinder 203 and stretch out, thereby make first pneumatic cylinder 203 send into the pipe fitting with lock ring 301 in, thereby make lock ring 301 carry out a support to the weak position of geminate transistor, thereby prevent to add the weak position of man-hour pipe fitting because the influence that causes produces the damage because of processing, so lock ring 301 can be so that the success rate of pipe fitting processing promotes, the difficult waste material that appears, thereby perfect course of working.
In addition, as an example, as shown in fig. 3, this example solves the problem that the support ring 301 supports different pipe diameters,
because the inside a plurality of second pneumatic cylinders 303 that is equipped with of lock ring 301, a plurality of sucking discs set up respectively in a plurality of second pneumatic cylinders 303 upper ends, when first pneumatic cylinder 203 pushes the lock ring 301 into inside the pipe fitting, the staff can stretch out through controlling second pneumatic cylinder 303, thereby adsorb a plurality of sucking discs on the pipe fitting inner wall, thereby make lock ring 301 to support the pipe wall of different internal diameters, thereby the application range of lock ring 301 has been enlarged, make lock ring 301 can adapt to the in service behavior when the pipe orifice is not uniform with other positions diameters of pipe simultaneously, make the application range of this device wider, the support effect of this device has been improved simultaneously.
In addition, as an example, as shown in fig. 3, this example solves the problem that the support ring 301 cannot extend into the pipe when the diameter of the support ring 301 is increased by the suction cup,
because a plurality of sucking disc standing grooves 302 all set up on lock ring 301, a plurality of sucking disc standing grooves 302 all are located the corresponding position of the sucking disc on lock ring 301, so can be through the shrink with second hydraulic cylinder 303 when stretching into the pipe fitting inside with the sucking disc shrink to sucking disc standing groove 302 in, thereby make the sucking disc can not enlarge lock ring 301's diameter, thereby avoid appearing because the existence of sucking disc makes inside the weak position of entering pipe fitting of lock ring 301 support, the actual diameter of lock ring 301 has been reduced as far as, thereby further the application range of this device has been increaseed.
In addition, as an example, as shown in fig. 4, this example solves the problem of leaving marks on the supporting portion,

In addition, as an example, as shown in fig. 5, this example solves the problem of driving the ring gear 401,
because the inside fixedly connected with first motor 402 of lock ring 301, fixedly connected with gear I403 on the output shaft of first motor 402, when the mark is done to needs, first motor 402 rotates and drives gear I403 to rotate, gear I403 rotates and drives ring gear 401 and rotate on lock ring 301, thereby ring gear 401 rotates and drives rotating ring 405 to rotate, thereby make mark brush 408 brush the mark at intraductal supporting part, the purpose of adopting L type slider 404 can prevent to make L type slider 404 drop because the vibrations of pipe in the course of working, thereby make ring gear 401 and I403 unable meshing of gear, lead to the unable normal rotation of rotating ring 405, thereby the effect of output mark can't be realized.
In addition, as an example, as shown in fig. 1-2, this example solves the problem of further allowing the support ring 301 to enter the tube from the center of the nozzle for support,
because the first pneumatic cylinder 203 of fixedly connected with in the middle of connecting portion 201, two anchor clamps slides are equallyd divide and are do not in connecting portion 201 both sides, so first pneumatic cylinder 203 can be located all the time by the fixed pipeline middle part of anchor clamps, all can get into inside the pipeline from the pipeline mouth to can support at the center, thereby reach better supporting effect, the difficult condition that the skew appears.
In addition, as an example, as shown in fig. 5 and 7, this example solves the problem of clamping pipes of different sizes,
because two equal sliding connection in connecting portion 201 both sides have sliding seat 202, sliding seat 202 can be through the fix with screw on connecting portion 201, there is connecting plate 204 through screw threaded connection on sliding seat 202, there is interchangeable anchor clamps 205 through screw threaded connection on the connecting plate 204, thereby the staff can adjust the width between a plurality of interchangeable anchor clamps 205 through the position of adjusting a plurality of sliding seats 202, thereby carry out centre gripping and fixing to different radial pipes, interchangeable anchor clamps 205 on the connecting portion 201 of the left and right sides are used for the both sides of centre gripping pipe fitting respectively, thereby the both ends of geminate transistors are fixed, simultaneously can change interchangeable anchor clamps 205 according to the scope of different pipe diameters, thereby it can be to the radial scope of centre gripping pipe fitting to increase this device, slide two sliding seat 202 and fix through screwing up the screw behind the suitable position, thereby carry out the centre gripping to the pipe fitting.
In addition, as an example, as shown in fig. 7 and 8, this example solves the problem of making the pipe rotatable to machine different parts,
because one side connecting portion 201 fixed connection is on gear shaft 103, and opposite side connecting portion 201 fixed connection is on pivot 502, and gear shaft 103 rotates to be connected on fixing base 101, and pivot 502 rotates to be connected on adjusting rotor plate 501, so make the pipe fitting can rotate certain angle after fixed by the centre gripping again for can rotate the pipe fitting man-hour, thereby process different positions, process the different face of pipe fitting.
