Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model counterdie frame component vertical view.
The specific embodiment
Present embodiment provides a kind of automotive oil tank thermal insulation board deep-drawing mould vehicle; Structure such as Fig. 1 are to shown in Figure 2; Comprise top mold frame assembly, counterdie frame component, once drawing assembly, secondary deep-drawing assembly, diagonal angle side cut assembly, pre-punched hole assembly and blank holder assembly; Once drawing assembly and secondary deep-drawing assembly are fixedly installed between said top mold frame assembly and the counterdie frame component; Said diagonal angle side cut assembly be located at said once drawing assembly around, said blank holder assembly is arranged on said counterdie frame component periphery, said pre-punched hole assembly is fixedly installed on the said counterdie frame component; Connect through guide pin bushing guide pillar assembly between said top mold frame assembly and the counterdie frame component.
Top mold frame assembly and counterdie frame component are made up of top mold frame 1, cope match-plate pattern 2, rebound 5, guide pillar guide pin bushing assembly 22, lower bolster 23, following mould bases 26, limited post assembly 31; The once drawing assembly is by once drawing punch 15, punch retainer 27, draw die 3, die block 4, stripper bolt 6, drawing stripper 7, draw assemblies such as discharging spring 8 and form; Draw and finish the back through stripper bolt 6, the effect of drawing stripper 7, drawing discharging spring 8; Part is released in matrix cavity, accomplished the discharging action.Draw the die material and use the XFD3M trade mark, once draw punch 15 materials and use the 50C trade mark.
The secondary deep-drawing assembly is made up of assemblies such as secondary drawing punch 16, little guide pillar assembly 17, caging bolt 18, secondary drawing springs 19; Secondary drawing punch 16 materials use the 50C trade mark; Left and right die cavity respectively uses two groups little guide pillar assemblies 17; Secondary drawing is accurately led, and left and right die cavity respectively uses five groups of rectangle springs, for secondary drawing provides pressure-pad-force.
Side cut assembly in diagonal angle is made up of assemblies such as corner cut punch 29, corner cut die 30, corner cut die blocks 28; Corner cut punch 29 is fixed in and draws on the die block 28; The corner cut die is connected with lower bolster 23 through the corner cut die block, and corner cut punch 29, corner cut die 30 all use the Cr12MoV material.
