The present invention will be described in detail below in conjunction with accompanying drawing and concrete preferred embodiment, so that advantages and features of the invention can be easier to be understood by those skilled in the art, these embodiment are only illustrative purposes, are not intended to scope of the present invention is limited.
See also Fig. 1 and Fig. 2, this heavy wall stretched parts 100 of the present invention's processing comprises base plate 101 and is arranged at the first boss 104 and second boss 105 of base plate 101 tops, wherein the first boss 104 is positioned at the top of the second boss 105 and is connected with the second boss 105, and the second boss 105 is positioned at the top of base plate 101 and is connected with base plate 101.The first boss 104 and the second boss 105 are cylindrical and its center is provided with a through hole 103, and described the first boss 104 comprises top plan the first plane 102.The long limit of base plate 101 is provided with a groove 106 to the larger side of through hole 103 centre distances.The first boss 104 becomes greatly to the second boss 105 wall thickness gradually from the first plane 102 1 ends, and the wall thickness of the second boss 105 is greater than the wall thickness of the first boss 104, and the wall thickness of the first boss 104 is greater than the thickness of base plate 101.
see also Fig. 3, be processing heavy wall stretched parts 100 as depicted in figs. 1 and 2, mould structure of the present invention comprises cope match-plate pattern 3, upper bolster 14, lower bolster 16 and die shoe 15, described upper bolster 15 is positioned at the top of the described drawing forming mold of heavy wall step by step, described cope match-plate pattern 3 is positioned at the below of upper bolster 14 and is connected with upper bolster 14, described lower bolster 16 is positioned at the top of the below of cope match-plate pattern 3 and die shoe 15 and is connected with die shoe 15, has been arranged side by side successively punching edge-trimming tool bit 1 in described cope match-plate pattern 3, the first forming blocks 2, the second forming blocks 4, the 3rd forming blocks 5, the 4th forming blocks 6, the 5th forming blocks 7, the 6th forming blocks 8, the 7th forming blocks 9, the 8th forming blocks 10, pierce punch 11, dressing stick 12 and blanking die 13 have been arranged side by side the first draw punch 17 successively in described lower bolster 16, the second draw punch 18, the 3rd draw punch 19, the 4th draw punch 20, the 5th draw punch 21, the first pier backwashes 22, the second pier backwashes 23, the 3rd pier backwashes 24 and shaping drift 25, described the first forming blocks 2 is with first draw punch 17 is corresponding matches, described the second forming blocks 4 is with second draw punch 18 is corresponding matches, described the 3rd forming blocks 5 is with the 3rd draw punch 19 is corresponding matches, described the 4th forming blocks 6 is with the 4th draw punch 20 is corresponding matches, described the 5th forming blocks 7 is with the 5th draw punch 21 is corresponding matches, described the 6th forming blocks 8 is backwashed 22 corresponding matching with the first pier, described the 7th forming blocks 9 is backwashed 23 corresponding matching with the second pier, described the 8th forming blocks 10 is backwashed 24 corresponding matching with the 3rd pier, described dressing stick 12 matches with shaping drift 25 is corresponding.
The quantity that is appreciated that above-mentioned a plurality of draw punch and forming blocks is preferred quantity, and the quantity of described a plurality of draw punchs and forming blocks can be Duoed or lack than preferred quantity, but the quantity of draw punch and forming blocks will be for matching.
Preferably, punching edge-trimming tool bit 1, the first draw punch 17, the second draw punch 18, the 3rd draw punch 19, the 4th draw punch 20, the 5th draw punch 21, the first pier backwash that 22, second pier backwashes that the 23, the 3rd pier backwashes 24, pierce punch 11, shaping drift 25 and blanking die 13 work successively according to sequencing when work.
Further, during mold work, as shown in Figure 4 and Figure 5 raw material strip 200 to be processed is placed on lower bolster 16, upper bolster 14 moves down and drives punching edge-trimming tool bit 1, strip 200 is positioned the punching processing in hole.Upper bolster 14 lifts afterwards, station of strip 200 reaches, and upper bolster 14 again moves down and drives the first draw punch 17 that the first forming blocks 2 moves down close correspondence, and strip 200 is stretched for the first time.Then upper bolster 14 lifts, station of strip 200 reaches, and upper bolster 14 again moves down and drives the second draw punch 18 that the second forming blocks 4 moves down close correspondence, and 200 stretchings place for the first time stretch for the second time to strip.
Be appreciated that, according to above-mentioned same mode, strip 200 constantly moves forward, when strip 200 stretchings place for the first time are advanced to the first pier and backwash 22 top, strip 200 the punching stretch place carried out 5 times and stretched for the first time this moment, all carried out overstretching action from the first draw punch 17 to the 5th draw punchs 21, stretched the first boss 104 and the second boss 105.The first pier backwashed and 22 coordinated 8 pairs of strip 200 stretchings place for the first time of the 6th forming blocks to carry out for the first time the pier work that reverses this moment, to increase the wall thickness of the first boss 104 and the second boss 105.Then the second pier backwashes and 23 coordinates 9 pairs of strip 200 stretchings place for the first time of the 7th forming blocks to carry out for the second time pier works that reverse, and the 3rd pier work that reverses is carried out in 10 pairs of strip 200 stretching place for the first time of 24 cooperation the 8th forming blocks of backwashing of the 3rd pier.Through three piers reverse work, the first boss 104 and the processed thickness near needs of the second boss 105.
Further, strip 200 continues to be advanced to pierce punch 11 places, and pierce punch 11 moves down and passes the first plane 102, and the first boss 104 is carried out punching processing, removes the top cover at 102 places, the first plane, processes through hole 103.Strip 200 continues to be advanced to shaping drift 25 places afterwards, dressing stick 12 moves down and coordinates corresponding 25 pairs of the first boss 104 of shaping drift, the second boss 105 and through hole 103 to carry out Shape correction, make the size that the first boss 104, the second boss 105 and through hole 103 reach to be needed, form a heavy wall stretched parts.
At last, strip 200 continues reach, and the heavy wall stretched parts that processes moves to blanking die 13 places, and blanking die 13 moves down die-cut, and the heavy wall stretched parts is separated from strip 200, forms the heavy wall stretched parts 100 of needs.
Like this, utilize the head that backwashes of a plurality of drawing and forming drifts and pier on mould to coordinate a plurality of forming blocks that the Multi-step forming of strip 200 is stretched and pier returns, punching and blanking, complete the processing to part at last.Make the boss and the through hole that process all meet dimensional requirement, and the wall thickness of boss is greater than the thickness of base plate.
Be different from prior art, the drawing forming mold of heavy wall step by step of the present invention can process the wall thickness of boss greater than the heavy wall stretched parts of base plate thickness, and production efficiency is high by stretching step by step and pier returns processing, and waste of material is few, and production cost is low.
The above is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
