Detailed description of the invention
Below, with reference to accompanying drawing, embodiment of the present utility model is described in detail.The utility model is not limited to the embodiment of following discloses, can be deformed into other form various.In addition, in order to the convenience illustrated, the size of structural element may have and zoom in or out in the accompanying drawings.
Fig. 1 is the schematic diagram according to the decompressor for riveting pressing rivet nut and sheet metal of the present utility model, Fig. 2 is the schematic diagram of decompressor convex mould of the present utility model, Fig. 3 is the schematic diagram of die in decompressor of the present utility model, and Fig. 4 is the partial enlarged drawing of the die shown in Fig. 3.
Referring to figs. 1 through Fig. 4, the decompressor for riveting pressing rivet nut and sheet metal comprises punch 1 and die 2, and wherein, punch is fixed on working face on press, and die is fixed on press table.
Punch 1 comprises convex mould pad 11 and drift 12, and convex mould pad 11 is arranged on press on working face, and drift 12 is arranged on convex mould pad 11, and convex mould pad 11 is for punch support 11 (as shown in Figure 2); Die 2 comprises die body 21 and supports the die backing plate 22 of die body 21, self-clinching nut alignment pin 23 be arranged on die body 21 top and on the position corresponding with drift 12, matrix cavity 26 is formed around self-clinching nut alignment pin 23, self-clinching nut alignment pin 23 is positioned at the center of matrix cavity 26, for playing the effect of location when self-clinching nut is placed on die body 21.In addition, be formed with die profile 24 and sheet metal part alignment pin 25 on die body 21 top, die profile 24 and sheet metal part alignment pin 25 match and to position the sheet metal having pre-punched hole.
Fig. 5 is the schematic diagram of the sheet metal part fixture in decompressor of the present utility model.As shown in Figures 1 and 5, sheet metal part fixture 3 is arranged on die backing plate 22, it comprises symbol type supporting surface 31 and is connected the support bar 32 supporting symbol type supporting surface 31, and this symbol type supporting surface 31 matches with sheet metal part profile and plays the effect of supporting and location sheet metal.Sheet metal part fixture 3 can particular production according to different parts.
Below, the operation principle of the decompressor for riveting pressing rivet nut and sheet metal of the present utility model is described in detail.
Before punching press, self-clinching nut (not shown) is passed self-clinching nut alignment pin 23 and is placed in the matrix cavity 26 of die 2, then the sheet metal having pre-punched hole is placed on self-clinching nut, the center of self-clinching nut and self-clinching nut alignment pin 23 is aimed at its center, hole having the sheet metal of pre-punched hole, and is positioned by die profile 24, sheet metal part alignment pin 25 and sheet metal part fixture 3 pairs of sheet metals.
