Detailed description of the invention
Combined type multi-position pipe mould utilizes the shaping floating core-pulling mechanism of two sleeve parts to control the turnover of loosing core of floating respectively to two of moulding pipe sections in FIG.In explanation described later, in main description Fig. 1, the formation of tubes in left side floats the structure of core-pulling mechanism and operation principle, it illustrates that the formation of tubes being substantially suitable for right side floats core-pulling mechanism, the two difference is mainly loosed core action reversed, installation site is different, and in addition as shown in Figure 2, the floating of left side looses core 1 for flat rod, as shown in Figure 3, the floating of right side looses core 1 ' for circle plug.
As shown in Figure 1, formation of tubes floats core-pulling mechanism can point upper, middle and lower three part and patrix wedge group, counterdie wedge group and counterdie wedge seat, patrix wedge group comprises connecting rod 6 and pinch roller 7, connecting rod 6 is hinged on the patrix (i.e. dynamic model) of mould, and pinch roller 7 is arranged on the lower end of connecting rod 6 rotatably.Counterdie wedge group comprises gathering sill seat 2, as shown in Figure 4, gathering sill seat 2 is made up of two plates 21, two plates 21 be arranged in parallel, arc skewed slot 210 on it corresponds to each other, composition graphs 5, gathering sill seat 2 there is cover plate 4, extension spring support 3 is had above cover plate 4, floating looses core 1 is slidably matched by bearing pin 100 and skewed slot 210, and is provided with extension spring between extension spring support 3 and this bearing pin, and action of reset spring is played in extension spring, skewed slot 210 plays guide effect, with in self adaptation formation of tubes process to the movement requirement of loosing core.
Get back to Fig. 1, Fig. 7, gathering sill seat 2 is fixed on sliding inclined wedge 10, sliding inclined wedge 10 is equipped with wearing plate 8, and wearing plate can ensure that the operating time life-span uses.Sliding inclined wedge 10 is fixed with fixed block 9, and it is for coordinating with described nitrogen cylinder 11, to promote sliding inclined wedge 10.
Continue with reference to Fig. 1, Fig. 7, counterdie wedge seat 15 is fixed on the counterdie (quiet mould) 14 of mould, counterdie wedge seat 15 provides inclined-plane, sliding inclined wedge 10 coordinates slidably on this inclined-plane, nitrogen cylinder (retractor device) 11 is fixed on counterdie wedge seat 15 by fixed block 12, its piston rod is connected on aforementioned fixed block 9, and the effect of nitrogen cylinder 11 is identical in fact with back-moving spring, namely keeps sliding inclined wedge 10 to be in original state.
As shown in Fig. 1, Fig. 7 and Fig. 9, the diameter of pinch roller 7 deducts the clearance distance of wearing plate 8 to positive stop 5, and be exactly counterdie wedge group horizontal motion stroke, positive stop 5 is fixedly installed on counterdie.Extension spring support 3 with float loose core 1 bearing pin extension spring link, ensure that floating looses core and 1 be in upper extreme position in off working state.Counterdie wedge seat 15 is responsible for the guiding of counterdie wedge group and spacing.When mould is descending, the active compression nitrogen cylinder 11 of counterdie wedge group, when mould is up, nitrogen cylinder 11 promotes the outwards movement of counterdie wedge group, get back to original state, deviate to float simultaneously and loose core 1, conveniently access pipe fitting (backhaul stroke is by the Stroke Control of nitrogen cylinder).
The operation principle of previous embodiment is: mould original state as shown in Figure 9, when starting working, patrix wedge group contacts with counterdie wedge group mold is descending, produce motive force, promote counterdie wedge group to slide along counterdie wedge seat, the floating rod of loosing core be arranged in counterdie wedge group enters pipe fitting 16 inner chamber depths, and mould closes, as shown in Figure 10, extrude tubulose profiled member, now, floating rod of loosing core is in final position.When mold is up, on two sides, wedge group moves upward and departs from lower wedge group, and the floating rod of loosing core of two sides, under the promotion of nitrogen cylinder, shifts out outside moulding pipe by lower wedge group, completes one action circulation, gets back to state as shown in Figure 9.In this course of work, float rod of loosing core, and self adaptation mould forming recess, can not produce interference.
The floating core-pulling mechanism volume of previous embodiment is little, carries nitrogen cylinder backhaul design, solve automobile longitudinal arm shaping after, plug of loosing core is in cantilever position, may to collide the problem of interfering during reset with tube wall die cavity.
In the aforementioned embodiment, the concrete shape of skewed slot 210 is main relevant with the forming process of pipe fitting, and pipe fitting is stamped in deformation process, and downward, the activity of horizontal direction that skewed slot 210 provides and the distortion of formation of tubes process adapt.
As shown in Figure 8, the formation of tubes core-pulling mechanism that floats being positioned at right side comprises gathering sill seat 2 ', sliding inclined wedge 10 ', wedge seat 15 ', cylinder 11 ', fixed block 12 ', 9 ', wearing plate 8 ', as previously mentioned, the gathering sill seat 2 that the formation of tubes in itself and left side floats in core-pulling mechanism, sliding inclined wedge 10, wedge seat 15, cylinder 11, fixed block 12, 9, the effect of wearing plate 8 is in fact identical, as shown in Figure 9, the promotion of the sliding inclined wedge 10 ' on right side is not promoted by swing connecting bar and pinch roller, but connect by patrix the inclined-plane of part 6 ' of cutting sth. askew and promote, same, the float driving of core-pulling mechanism of the formation of tubes on right side also can adopt this way of propelling.
Although the present invention with preferred embodiment openly as above, it is not that any those skilled in the art without departing from the spirit and scope of the present invention, can make possible variation and amendment for limiting the present invention.Therefore, every content not departing from technical solution of the present invention, any amendment done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all fall within protection domain that the claims in the present invention define.
