Plate is added to man-hour, plate is positioned on loose plug 32 and is positioned, patrix descending and contact with plate after, due to patrix applied pressure, loose plug 32 will move along patrix operative orientation, there is deformation in elastic reset part 34 now.After plate has been located, can process the side of plate; After machining, patrix is up, and loose plug 32 can reset after losing pressure under the effect of elastic reset part 34, so that the carrying out of next manufacturing procedure.
Known by foregoing description, the edge forming mould of the plate that the embodiment of the present invention provides adopts loose plug 32 to locate plate, this loose plug 32 has certain height with respect to die shoe 31 under the effect of elastic reset part 34, and then has equally certain height after making plate be positioned on loose plug 32.Now, even if there is resilience in plate after a upper operation, plate be also difficult for die shoe 31 on structure interfere, then improve the positioning precision of plate.Obviously,, than the content of introducing in background technology, the edge forming mould that the embodiment of the present invention provides can improve the formed precision of plate.
Stability while movement in order to improve loose plug 32, the embodiment of the present invention is offered installing hole on die shoe 31, and one end of elastic reset part 34 is positioned at installing hole, and the other end acts on mutually with loose plug 32.Particularly, elastic reset part 34 can with loose plug 32 butts, both also can be fixedly connected with.Visible, the distortion that above-mentioned installing hole can be elastic reset part 34 provides guiding, the phenomenon such as occurs rocking after avoiding elastic reset part 34 stressed, and situation appears rocking etc. in the loose plug 32 of avoiding acting on mutually with it with this.In this scheme, elastic reset part 34 still can be selected rubber part, but for larger elastic-restoring force is provided, elastic reset part 34 can be preferably to spring.
In a kind of embodiment, the part surface of above-mentioned elastic reset part 34 or all surfaces can be fitted with the inwall of installing hole, but this kind of mode can increase frictional force between the two undoubtedly, cause both easily to occur wearing and tearing.In order to alleviate this problem, the elastic reset part 34 that the embodiment of the present invention provides also can with installing hole matched in clearance, slow down with this wearing and tearing that elastic reset part 34 produces when the installing hole internal strain, extend the service life of edge forming mould.
Further in technical scheme, in order to increase to a greater degree the stability of elastic reset part 34 stressed rear motions, can match with two or more above-mentioned installing holes in insert 32 bottom surface of single-unit activity,, can adopt two or more elastic reset parts 34 simultaneously and single-unit activity 32 effects mutually of inserting.32 do the used time than only adopting an elastic reset part 34 and single-unit activity to insert, the center of gravity of loose plug 32 is difficult for definite situation, such scheme is not prone to the situations such as inclination while loose plug 32 being moved by multiple application points, achieves the above object with this.The concrete number of elastic reset part 34 is determined according to the specification of the size of loose plug 32, elastic reset part 34 etc.
Further, what the embodiment of the present invention provided insert also can comprise being fixedly installed in and fixedly insert 33 on die shoe 31, and this is fixedly inserted on 33 and has the working face for locating plate.At the end of travel place of loose plug 32, the plate locating surface of loose plug 32 is coplanar with 33 the working face fixedly inserted, and both locate plate simultaneously.Understandably, in the time that the face size that needs on plate to locate is constant, adopting fixedly inserts 33 can effectively reduce the size of loose plug 32, and then reduces loose plug 32 and put on the active force of elastic reset part 34, prevents that elastic reset part 34 is stressed excessive and lost efficacy.Even more important is a bit, when processing plate, 33 invariant positions on die shoe 31 of fixedly inserting, loose plug 32 can change position with respect to die shoe 31, in the time rising under the reset force effect of loose plug 32 at elastic reset part 34, plate after moulding and fixedly insert and have gap between 33, under the effect in this gap, operating personnel can take out the plate after moulding easily.
The shift motion control of loose plug 32 can directly show in the selection of elastic reset part 34, when elastic reset part 34 arrives nature, loose plug 32 will stop, but because its elastic performance after elastic reset part 34 prolonged exercises will change to some extent, cause the shift motion of elastic reset part 34 to be not easy to control.For this reason, the embodiment of the present invention arranges positive stop lug boss 35 on loose plug 32, fixedly inserts on 33 and has limited impression, has relatively with above-mentioned positive stop lug boss 35 on this limited impression, and is positioned at the confined planes on the shift motion of positive stop lug boss 35.When loose plug 32 moves, in the time that positive stop lug boss 35 connects with the confined planes gear on limited impression, the movement of loose plug 32 can be prevented from.Certainly,, under this scheme, on positive stop lug boss 35, near the distance between surface and the confined planes of confined planes, be the shift motion of loose plug 32.
Above-mentioned positive stop lug boss 35 can be arranged at arbitrary position of loose plug 32 outer surfaces, but for the ease of processing, positive stop lug boss 35 in the embodiment of the present invention can be positioned at the bottom of loose plug 32, and now, the lower surface of positive stop lug boss 35 can fit with the bottom surface of installing hole.Thus, the limited impression of fixedly inserting on 33 can be the groove structure connecting with installing hole, and its processing technology is comparatively simple.
In preferred technical scheme, fixedly insert on 33 and have the spigot surface fitting with the lateral surface of loose plug 32, particularly, loose plug 32 can be arranged at 33 the side of fixedly inserting, and above-mentioned spigot surface is 33 the lateral surface of fixedly inserting.Pass through said structure; loose plug 32 under the active force of patrix or elastic reset part 34 with respect to fixedly inserting 33 while moving; fixedly inserting 33 will provide more guide effect to the movement of loose plug 32; improve plate locating surface on loose plug 32 positional precision before and after mobile with this, ensure that with this loose plug 32 meets the demands to the positioning precision of plate.
But above-mentioned spigot surface only contacts with the part lateral surface of loose plug 32, a little less than its guide effect relatively for loose plug 32.Therefore, can offer the through hole of accommodating loose plug 32 on 33 fixedly inserting, this through hole communicates with the installing hole on die shoe 31, and its inwall will be served as above-mentioned spigot surface.Known, using the inwall of through hole as spigot surface, can greatly increase the guiding area of loose plug 32,33 encirclements of inserting that are fixed of whole loose plug 32, it is with respect to after the whole shift motion of 33 motion of fixedly inserting, the variation that plate locating surface produces with respect to the position of die shoe 31 is less, impels edge forming mould positioning precision to plate in multiple working cycles higher.
More preferably, the quantity of above-mentioned through hole can be two or more, increases with this quantity of loose plug 32 of 33 encirclements of inserting that is fixed, and the location that each loose plug 32 is provided plate is more accurate.
Only by the mode of explanation, some example embodiment of the present invention is described above, undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention in the situation that, can revise described embodiment by various mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the claims in the present invention protection domain.
