The utility model relates to a kind of pipe fitting crimping erecting tools, uses when being adapted at PAP and connecting with pipe fitting.

At present, PAP mostly adopts threaded fitting version when it is coupled to each other, use the mutual interlock of screw thread when being coupled to each other, also have to use and swing to teeth version, the outside is added with pressure sleeve again and compresses pipe fitting, make between pipe fitting and the multiple tube and closely cooperate, above draw bail all can not reach the purpose that closely cooperates, firmly connects, for guaranteeing that pipe fitting and PAP closely cooperate, preferably adopt the method for direct pressing on pipe fitting, a kind of crimping pipe wrench is provided, and specifically is exactly the specific purpose tool of crimping pipe fitting.

The purpose of this utility model provides a kind of card pressure pipe part electronic Press Plier, utilizes this Press Plier formation impression of directly exerting pressure on connection pipe fitting, to reach close-fitting purpose between pipe fitting and the multiple tube.

Structural design of the present utility model is achieved in that the structure of this Press Plier is by operating grip; middle leading screw; Hubei Province, opening Hubei Province of nut and end three part are formed (as shown in Figure 1); wherein in the operating grip power knob is housed; change-over switch; direct current generator; change-over switch joins by power knob and outside dc source; at motor output end gear reduction unit is housed; speed reducer output shaft is connected to pressure protector; protector connects (as shown in Figure 2) by leading screw with opening Hubei Province; pressure protector is made up of interior overcoat; interior cover one termination and decelerator output are fixedly connected; the other end is a circular sleeve; central cross is equipped with compression spring; the compression spring two ends connect ratchet respectively; ratchet is the sheet that pulls out that a center has forward rotating shaft; closely cooperate in the outside of interior cover and to be with overcoat; in overcoat with pull out the corresponding place of sheet and have forward groove; pulling out sheet one side enters in the groove just; the exit of overcoat directly fixedly docks with the leading screw of centre; the outside of leading screw is with nut; the front end of nut connects slide block (as shown in Figure 3); below the slide block two symmetrical contact rollers; each is taken turns to be equipped with and compresses wheel shaft; the contact roller front end is equipped with connecting plate; the connecting plate center is a connecting pin; opening Hubei Province (as shown in Figure 4) is equipped with in the connecting plate front portion; back-moving spring is equipped with at center, opening Hubei Province; the screw alignment pin is equipped with in both sides; synchronous roller bearing is housed in the middle of two alignment pins; opening Hubei Province front end is circular jaw; in jaw, be provided with three horizontal semicircle protruding teeth; form the horizontal full circle indenture in three roads behind the spinning and on the pipe fitting pressure rings; for the connecting pin latch connects, can there be all size in opening Hubei Province as required between opening Hubei Province and the connecting plate.

Advantage of the present utility model: compact conformation, easy to install, on the pipe fitting pressure rings, moderately exert pressure, produce indenture, make the permanent pressure that produces certain value between pipe and the pipe fitting, closely cooperate between the assurance, connect firmly, durable in use.

The utility model detailed structure is provided by following examples and accompanying drawing.

Fig. 1 is the electronic Press Plier overall construction drawing of card pressure pipe part.

Fig. 2 is the electronic Press Plier pressure protect of card pressure pipe part structure chart.

Fig. 3 is card electronic Press Plier middle screw rod of pressure pipe part and nut structure figure.

Fig. 4 is the electronic Press Plier opening of card pressure pipe part Hubei Province structure chart.

Its structure is by shown in the accompanying drawing, and forward handle partly has action button 1, pole changer 2, direct current generator 3 and decelerator 4, wherein change-over switch directly and external dc power join.Decelerator 5 joins with protector 6; decelerator 5 connects as shown in Figure 2 with protector 6; protector one end connects with the decelerator output; other end outside is a cover 14 in the protector; overcoat is 15; in the interior cover spring 16 is housed; ratchet 17; ratchet one side is in the groove 18 of overcoat; the overcoat front end connects with leading screw 7; screw mandrel 7 outsides are with nut 8, and leading screw 7 front ends are equipped with slide block 11, and both sides are equipped with contact roller 10 and are compressed wheel shaft 9; the front is fixed with connecting pin 12; connecting plate 23 is housed on connecting pin; screw alignment pin 20 is equipped with in opening Hubei Province 19 on opening Hubei Province; fixedly roll 21 and the back-moving spring 22 at center, and fit in the inclined-plane, both sides of the both sides of contact roller 10 and back, opening Hubei Province; be respectively equipped with three horizontal semicircle protruding teeth in the jaw of opening Hubei Province, can there be all size in opening Hubei Province on demand.

Its course of work: push down two opening Hubei Province afterbodys before the work, jaw opens rear tubular member to be put into, and unclamps hand, and opening Hubei Province closes up under the effect of tail springs naturally, is affixed on the pressure rings of pipe fitting.Make the commutation spanner be in forward during work earlier; push down play button; motor begins rotation; helical teeth by the motor shaft front end passes to other gears of reductor; slow down through three grades of reductors; torque increases, and overlaps in the rear drive overload protection, has the bowl type overcoat of two half round cut by the ratchet and the inboard circle of forward; give bowl type overcoat with transmission of power; bowl type overcoat is given coupled spiral handspike flute profile leading screw with transmission of power, during the leading screw rotation circular motion is become the nut rectilinear motion, and power further increases; when power is excessive; the protector ratchet overturns when surpassing the pressure of spring because of torsion is excessive, and cover is thrown off with overcoat in making, and has decontroled reinforcing this moment; the protection current of electric is excessive and burn out; ordinary circumstance lower nut and slide block are fixedly linked, and promote slide block and advance in slideway, have also retrained the motion mode of nut simultaneously.When the pressure wheel on the slide block is advanced, promote afterbody inclined-plane, two opening Hubei Province, the power that will advance is decomposed into two bigger outside power, act on opening Hubei Province afterbody, by the leverage of screw alignment pin two power are amplified again, produce two inside pressure at jaw, pipe fitting is exerted pressure, be respectively equipped with three protruding teeth of semicircle in the upper jaw of opening Hubei Province, can on the pipe fitting pressure rings, form the horizontal full circle indenture in three roads after exerting pressure, make its plastic deformation, produce permanent pressure, pipe fitting and pipe are coupled together pipe.
