A kind of expanding deformation tooling of plastic pipe, as shown in Figure 1, include handle 1 and expanding head 2 on handle 1, with
And the cam mechanism being arranged on expanding head 2；The handle 1 is equipped with the driving mechanism for driving cam means work；It is described
Cam mechanism includes two cams 4 being correspondingly arranged on expanding head 2, and the gear teeth 5 are equipped on two cams 4, and the two passes through the gear teeth 5
Engagement；The expanding head, which is equipped with, is used for cams mounted fitting groove 3, and one end that each cam protrudes into fitting groove 3 passes through shaft 6
It is rotatably installed on expanding head；The driving mechanism includes the bull stick 7 being rotatablely installed on handle, and bull stick 7 protrudes into the one of expanding head
End is equipped with the transmission component for driving cam to rotate, and the other end is equipped with the handwheel 8 for driving bar rotation.
The transmission component includes the master bevel gear 10 being arranged on bull stick 7, and the shaft is equipped with and 10 phase of master bevel gear
The secondary bevel gear 11 of engagement；When needing to carry out expanding processing, worker can first be protruded into expanding head 2 in plastic pipe, later
Handwheel can be rotated manually, make handwheel that the master bevel gear 10 on bull stick and bull stick be driven to rotate, master bevel gear will drive secondary cone
Gear 11 and shaft 6 rotate, so that the gap between two cams be made to become larger, cam can withstand the inner wall of tubing, and completion pair
The expansion of plastic pipe internal diameter, during actual use, worker can according to processing need constantly to convert expanding position come
Complete the expanding of tubing entirety；
When needing to carry out deformation processing, the tubing of minor diameter can be placed between two cams by worker, Zhi Houtong
Crossing rotation handwheel makes the gap between two cams 4 become smaller, to enable two cams grip plastic tubing as pliers, completes
To the deformation operation of plastic pipe；This tooling not only may be implemented to carry out expanding processing to plastic pipe internal diameter, can also be right
Plastic pipe is clamped deformation processing, so this tooling can be very good the expanding deformation processing for meeting plastic pipe, and
And this tooling operate it is very convenient, substantially increase plastic pipe processing efficiency and convenience.
It is equipped with positioning bracing wire 12 different from one end of shaft on the cam 4, the both ends for positioning bracing wire are separately fixed at two
On cam；The maximum angle that two cam sheddings can be limited by setting positioning bracing wire makes two when worker rotates handwheel
When cam shedding expands, positioning bracing wire can be strained and fixed two cams, make worker that can not continue to rotate handwheel, to limit
The firmly expanding range of plastic pipe makes this tooling that the control processed to caliber may be implemented, it is expanding to greatly improve plastic pipe
The precision and efficiency of processing.
The positioning bracing wire 12 can use wirerope, and wirerope has good structural strength, and when use is not susceptible to
Fracture, wirerope can preferably limit the rotational angle of two cams；The cam is equipped with to be drawstring through for positioning
Through-hole, positioning is drawstring through one end of through-hole by the fixation of wire line hitch 13, and wire line hitch 13 can be directly used existing
Steel moulds sling, can be very good for wirerope to be fixed on cam by wire line hitch 13, and also by setting wire line hitch
The length of wirerope can be very easily adjusted, to adjust the rotational angle of two cams, this tooling may be implemented pair
The control of expanding length further improves the applicability of tooling, and this tooling is made to be adapted to the expanding of a variety of caliber tubing
Or deformation processing.
One end that the bull stick 7 stretches out handle is equipped with belt pulley 9, and the belt pulley can connect external driving device,
As long as belt pulley positive and negative rotation can be made, belt pulley is allow to drive two cam foldings；After the completion of expanding deformation processing,
Worker can also separate belt pulley with driving device, and rotating handwheel manually makes cam playback；It can also be made by the way that belt pulley 9 is arranged
This tooling can be directly connected to driving belt use, saved manpower, reduced the labor intensity of worker, by being arranged on cam
Positioning bracing wire 12, even if driving belt does not stop operating, two cams can also stop operating after turning to certain angle, from
And the expanding accuracy of this tooling is substantially increased, further improve the processing efficiency of plastic pipe.
The invention structure is simple, easily operated, can be adapted for the expanding deformation processing of a variety of plastic pipes；It is this
The expanding processing to plastic pipe internal diameter not only may be implemented in tooling, can also realize the pinching deformation processing to plastic pipe,
Substantially increase the efficiency and convenience of plastic pipe processing；The maximum of two cam sheddings can be limited by the way that bracing wire is arranged
Angle makes this tooling that the control processed to caliber may be implemented, greatly improves to limit the expanding range of plastic pipe
The precision and efficiency of the expanding processing of plastic pipe；By the way that belt pulley is arranged on bull stick, human cost is further saved, is dropped
The low labor intensity of worker；By the positioning bracing wire being arranged on cam, even if driving belt does not stop operating, two cams exist
Turning to after certain angle can also stop operating, to substantially increase the expanding accuracy of this tooling, further improve
The processing efficiency of plastic pipe.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection scope within.
