Detailed description of the invention
For making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.
Consult Fig. 1 and Fig. 2, the present invention is applied on flanging die, flanging die comprise a counterdie 1 and counterdie 1 with the use of patrix 2, patrix 2 is also provided with the material pressing core 8 of compacting workpiece.The invention provides Anti-jamming structure after a kind of die flanging, comprise the flange parts 5 that pair of workpieces carries out flange process, wherein, comprise a support workpiece and the buoyant block 6 risen by workpiece, described buoyant block 6 is arranged at the top of lower mould 1, be provided with elastomeric element 9 bottom described buoyant block 6, elastomeric element 9 promotes buoyant block 6 toward rising under the effect of elastic-restoring force.
Further, after described die flanging, Anti-jamming structure also comprises limiting component 7, described limiting component 7 is connected to lower die tip and extends in buoyant block 6, described limiting component 7 comprises one and carries out spacing stopper protrusion 71 to buoyant block 6 in vertical direction, the buoyant block hole portion of installing described limiting component 7 is provided with in described buoyant block 6, the aperture, top in described buoyant block hole portion is larger than bottom aperture, aperture, bottom is less than described stopper protrusion 71 diameter, buoyant block 6 is pushed upwardly by resilient force, until the lower edges in buoyant block hole portion in buoyant block 6 and stopper protrusion 71 contact, stopper protrusion 71 hinders buoyant block 6 to continue to rise, play the position-limiting action of vertical direction.
In the present embodiment, described limiting component 7 is a bolt, and stopper protrusion 71 is the bolt head of bolt.Certainly, limiting component 7 of the present invention is not limited in the form being set to bolt, can also be set to the form such as postive stop baffle, stop collar.Limiting component 7 is set to a bolt, utilizes the feature that bolt head diameter is larger, and carry out in vertical direction to buoyant block 6 spacing, structure is simple, reliable, and the installation of bolt is also very convenient, quick.
Further, described lower mould 1 is also provided with the lower nib portion 11 holding described elastomeric element 9.Preferably, described elastomeric element 9 is spring, and elastomeric element of the present invention is not limited in spring, and shell fragment is also a kind of feasible embodiment.
Further, as shown in Figure 3, the bottom of described flange parts 5 is provided with the second guide part 4, described lower mould 1 is provided with the first guide part 3, described first guide part 3 and the second guide part 4 are slidably connected, and flange parts 5 are slidably connected secondary reciprocating by this.In the present embodiment, described first guide part 3 is recessed V-arrangement slide block, described second guide part 4 is convex V-arrangement slide block, flange parts 5 will inevitably be subject to the active force of workpiece to it when carrying out flange operation to workpiece, the secondary sliding fulcrum as flange parts 5 that is slidably connected of the first guide part 3 and the second guide part 4 composition, can be flange parts 5 and supporting force is provided, turn-up process flange parts 5 are run more steady, avoid the situation of play to occur; Moreover the first guide part 3 and the second guide part 4 pairs of flange parts 5 play a part guiding, flange parts 5 move along this secondary direction of sliding that is slidably connected.
As other embodiments of the present invention, first guide part 3 can be set to the forms (not indicating in figure) such as arcs of recesses slide block, recessed square slider, second guide part 4 can be set to the forms such as convex slide block, convex square slider, and the shape size of the first guide part 3 and the second guide part 4 is adaptive.
In the present embodiment, described flange parts 5 are a flange insert, insert is embedded in mold cavity with fixed parts such as bolts the part being easy to change, the frequency that flange parts 5 and workpiece touch is very high, easy wearing and tearing, replacement frequency is higher, and the flange parts being set to flange insert are applicable to being applied in this type of flanging die structure.
Be below workflow of the present invention:
Consult Fig. 2, A condition is the state that workpiece 10 presents after the processing of a upper operation, the incomplete flange of workpiece under this state.Flange parts 5 move along the first guide part 3 and the second guide part 4 glide direction, touch with workpiece and make workpiece 10 by A condition flange to B state, under B state, the edge of workpiece 10 and horizontal direction are an acute angle being slightly less than 90 degree, if now depanning up will be mentioned workpiece, can be blocked by buoyant block 6 edge, so need first to move right past for workpiece, but limiting due to the shape of counterdie at C place, workpiece cannot move to right in this state.Patrix up mentions rear material pressing core 8 no longer workpiece pressing and buoyant block 6, under restoring force effect, buoyant block 6 is up promoted by the elastomeric element 9 compressed, the workpiece be positioned on buoyant block 6 is also up promoted a segment distance, until the buoyant block hole portion lower edges of buoyant block 6 touches the stopper protrusion 71 of limiting component 7.Workpiece 10 is by after jack-up, and the C place of workpiece 10 and counterdie 1 leaves an intersegmental gap, and this gap allows workpiece 10 toward moving right a segment distance, up can mention smoothly, complete depanning after workpiece moves to right.
The present invention is by providing Anti-jamming structure after a kind of die workpiece flange, by arranging the buoyant block that workpiece can be driven to rise, the elastic force of elastomeric element makes buoyant block rise, workpiece remakes after rising and moves horizontally so that workpiece takes out, and solves after the turnup structure of prior art carries out flange to workpiece and causes workpiece to be easily stuck, is difficult to the problem of taking off due to counterdie shape and structure feature.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
