Accompanying drawing explanation
Fig. 1 is the structural representation of the annulus part processing mold of an embodiment;
Fig. 2 is another structural representation of the part of annulus shown in Fig. 1 processing mold.
Detailed description of the invention
As depicted in figs. 1 and 2, the annulus part processing mold that provides of the utility model one embodiment is for being processed to form an annulus part 20 to a sheet material 10.
Sheet material 10 shown in Fig. 1 forms in the stamped from sheetstock of plane by one, it has the first bending segment 11, second bending segment 12 and the 3rd bending segment 13 that connect successively, the first, the bending direction of the 3rd bending segment 11,13 is identical, the bending direction of the second bending segment 12 is contrary with the bending direction of the first bending segment 11, the first, the development length of the 3rd bending segment 11,13 is 1/4th girths of annulus part 20, and the development length of the second bending segment 12 is 1/2nd girths of annulus part 20.This annulus part 20 by one in the sheet material of plane through twice punch forming, the annulus part processing mold that the utility model provides is for carrying out second time punching press, to form the annulus part 20 shown in Fig. 2 to forming sheet material 10 as shown in Figure 1 after a punching press.Be appreciated that the sheet material 10 shown in Fig. 1 can coordinate via the arc convex of two different directions to be stamped to form.
The counterdie 40 that this annulus part processing mold comprises patrix and coordinates with patrix.Described patrix comprises columned briquetting 31.Described briquetting 31 for when patrix moves towards counterdie 40, the second bending segment 12 of sheet material 10 described in punching press.The radius of described briquetting 31 equals the radius of annulus part 20.
Described counterdie 40 is provided with the machined surface 42 of level, described machined surface 42 is provided with an inner concave 44, described inner concave 44 is provided with needle roller 43 with the junction of machined surface 42, and described inner concave 44 forms semicircular die cavity 41, and the radius of described die cavity 41 equals the radius of annulus part 20.As shown in Figure 2, when briquetting 31 moves towards counterdie 40, the half of the cross section of briquetting 31 is just contained in this die cavity 41.
As shown in Figure 1, before the described sheet material 10 of processing, sheet material 10 is placed on the machined surface 42 of counterdie 40.Particularly, first, the 3rd bending segment 11,13 of described sheet material 10 is placed on described machined surface 42, second bending segment 12 is between inner concave 44 and briquetting 31, and the first, the 3rd bending segment 11,13 protrudes out away from briquetting 31, and the second bending segment 12 protrudes out towards briquetting 31.
In the process that patrix moves towards counterdie 40, briquetting 31 moves closer to the second bending segment 12 of sheet material 10, makes the second bending segment 12 back-flexing and is contained in die cavity 41.When the second bending segment 12 starts back-flexing distortion, the junction of the second bending segment 12 and the first bending segment 11, and second junction of bending segment 12 and the 3rd bending segment 13, contact with the junction of inner concave 44 with machined surface 42 respectively, namely the position contact of needle roller 43 is also set, needle roller 43 is subject to the impact of sheet material 10 and rolls, thus the frictional force that the region of interest reducing sheet material 10 and mould produces, avoid sheet material 10 surface in forming process to be scraped off impaired.
As shown in Figure 2, when patrix is positioned at end of travel place, briquetting 31 is contained in after in die cavity 41, and sheet material 10 completes deformation, and the annulus part 20 of formation is wrapped in the periphery of briquetting 31.Wherein, form corresponding second bending segment 12 of bottom half cycle of annulus part 20, it is between briquetting 31 and inner concave 44, and form top half cycle correspondence the first, the 3rd bending segment 11,13 of annulus part 20, its correspondence is wrapped in the top half cycle of briquetting 31.
Further, in certain embodiments, one end of described briquetting 31 is fixedly connected with patrix, and the other end is free end.Annulus part 20 after shaping can take out from this free end from briquetting 31.
Further, can arrange thimble on described patrix, the direction of motion of described thimble is parallel to the axis of briquetting 31, and described thimble is used for the annulus part 20 after shaping to eject briquetting 31.
Understandably, in some other embodiments, described thimble can be arranged on described counterdie, and the direction of motion of described thimble is parallel to the axis of briquetting 31, and described thimble is used for the annulus part 20 after shaping to eject briquetting 31.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this description is recorded.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
