Abstract
The utility model relates to a die, in particular to a multi-process shaping combined die used for processing specific workpieces. The multi-process shaping combined die comprises a lower die holder, wherein an inner die corresponding to the conical surface shape of the workpieces is fixed in the lower die holder, a stripper plate used for bearing flange faces is arranged above the lower die holder and is electrically connected with the lower die holder, and the inner die penetrates through the stripper plate. An upper die comprises an upper die holder, an outer die used for forming the conical surfaces of the workpieces is arranged in the upper die holder, and a press rod used for continuing to forge and press the tops of the workpieces to form a downwards concave pier-shaped structure is arranged in the outer die. The multi-process shaping combined die is characterized in that an ejector rod used for downwards pressing the stripper plate in advance in the downwards pressing process is fixed in the upper die holder. The multi-process shaping combined die is additionally provided with the ejector rod which compresses the stripper plate of a lower die in advance, meanwhile the outer die enters the scope of the inner die, the top surface is subjected to forging and pressing, the stretching conical surfaces are shaped, and finally the flange faces are shaped. Materials flow from top to bottom in the whole process so that the phenomenon of bad products of the original design is effectively eliminated.
Description
Technical field
The utility model relates to a kind of mould, especially a kind of multiple operation shaping assembling die of processing specific workpiece.
Background technology
Workpiece shown in Figure 1 comprises the flange face 1 of bottom, a conical surface 2 upwards stretches at the middle part of flange face, top planes at the conical surface 2 comprises a recessed pier shape structure 3, in the prior art, when processing this workpiece, adopt mould as shown in Figure 2 to process, as shown in Figure 2, this mould comprises that counterdie comprises a die shoe 4, the internal mold 5 that the corresponding workpiece conical surface 2 shapes are fixedly arranged in the die shoe 4, die shoe 4 tops are provided with the stripper 6 of carrying flange face 1, and stripper 6 is connected with die shoe 4 elasticity, and internal mold 5 passes stripper 6; Patrix comprises a upper bolster 7, is provided with the external mold 8 that the workpiece conical surface 2 is formed in the upper bolster 7, is provided with in the external mold 8 depression bar 9 that forging and pressing form recessed pier shape structure is continued at the workpiece top.Existing mould is when work, and the flange section to last operation carries out binder earlier, again the stretching conical surface is carried out shaping, and the pier shape to the top is forged and pressed at last.This processing mode causes the stretching conical surface and flange face corner crackle easily, and forging and pressing back material squeezes resilience and flange face, conical surface central shaft and pier shape structure concentricity problem of unstable.
Summary of the invention
The utility model provides a kind of processing work surfacing, the multiple operation shaping assembling die of resilience and good concentricity not.
To achieve these goals, the utility model adopts following technical scheme:
It comprises a die shoe, and the internal mold of corresponding workpiece conical surface shape is fixedly arranged in the die shoe, and the die shoe top is provided with the stripper of carrying flange face, and stripper is connected with die shoe elasticity, and internal mold passes stripper; Patrix comprises a upper bolster, be provided with the external mold that the workpiece conical surface is formed in the upper bolster, be provided with in the external mold depression bar that forging and pressing form recessed pier shape structure is continued at the workpiece top, its improvement is: fix a push rod that presses down stripper in the process of pressing down in advance in the described upper bolster.
Owing to adopted said structure, multiple operation shaping assembling die of the present utility model has appended push rod, and this structure is compression counterdie stripper earlier, make external mold enter the internal mold scope simultaneously, end face being forged and pressed again, then the stretching conical surface is carried out shaping, is that flange face is carried out shaping at last.Whole process flows material from top to bottom, has effectively eliminated intrinsic product bad phenomenon.
Description of drawings
Fig. 1 is the structural representation of processing work;
Fig. 2 is the structural representation of existing processing mold;
Fig. 3 is the die opening state cross section structure schematic diagram of the utility model embodiment;
Fig. 4 is the mold closing state cross section structure schematic diagram of the utility model embodiment.
Among the figure: flange face 1, the conical surface 2, pier shape structure 3, die shoe 4, internal mold 5, stripper 6, upper bolster 7, external mold 8, depression bar 9, push rod 10.
The specific embodiment
As shown in Figure 3 and Figure 4, the multiple operation shaping assembling die of present embodiment comprises a die shoe 4, and the internal mold 5 of the corresponding workpiece conical surface 2 shapes is fixedly arranged in the die shoe 4, and die shoe 4 tops are provided with the stripper 6 of carrying flange face 1, stripper 6 is connected with die shoe 4 elasticity, and internal mold 5 passes stripper 6; Patrix comprises a upper bolster 7, be provided with the external mold 8 that the workpiece conical surface 2 is formed in the upper bolster 7, be provided with in the external mold 8 depression bar 9 that forging and pressing form recessed pier shape structure is continued at the workpiece top, fix a push rod 10 that in the process of pressing down, presses down stripper 6 in advance in the described upper bolster 7.
During work, upper bolster 7 presses down, the push rod 10 that is positioned on the upper bolster 7 at first contacts and presses down stripper, make external mold 8 enter internal mold 5 scopes simultaneously, the depression bar that be arranged in external mold 8 this moment forges and presses sheet material, forms pier shape structure, and external mold 8 continues to descend then, with internal mold 5 the stretching conical surface being carried out shaping, is that flange face is carried out shaping at last.Whole process flows material from top to bottom, has effectively eliminated intrinsic product bad phenomenon.
The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
