Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 and Figure 2, the upwards Bending Rectification Mechanism of the present embodiment, comprises upper die component and lower mold assemblies, and the structure of upper die component is: comprise upper bolster 1, upper die plate 2, punch retainer 3 and stripper 6 are installed below upper bolster 1 successively, stripper 6 are installed and corrects punch 4; The structure of lower mold assemblies is: install die backing plate 9 and die block 8 above die shoe 10 successively, die block 8 is installed the correction die 5 matched with correction punch 4, lateral attitude, upper bolster 1 one end is installed the first wedge bar 12, upper bolster 1 vertical direction passes through bolt 11 and spring fitting second wedge bar 13, first wedge bar 12 top and the second wedge bar 13 upper end and abuts against; The structure correcting die 5 is as follows: correct die 5 left end head and be provided with a boss, boss left side is provided with the inclined-plane 501 of indent, offers spring groove 502 below inclined-plane 501, corrects die 5 right-hand member and arranges wedge-shaped indentation 503; Dig the groove relative with spring groove 502 in the middle part of die block 8, in groove and spring groove 502, place spring 15; Die shoe 10 installs material lift block 7 by securing member, and material lift block 7 is successively through die backing plate 9 and die block 8; Correct punch 4 and correct place work piece 14 between die 5, abutting with material lift block 7 top below workpiece 14.
Second wedge bar 13 lower end is provided with the first inclined-plane, and the second wedge bar 13 to coordinate with the wedge-shaped indentation 503 of correction die 5 through its first inclined-plane after upper die plate 2, punch retainer 3 and stripper 6 successively and abuts.
First wedge bar 12 top bottom surface is provided with the 3rd inclined-plane, and the second wedge bar 13 upper end is provided with the second inclined-plane matched with the 3rd inclined-plane.
Operation principles of the present invention is as follows:
Under normal circumstances, need bending excessive when punch and die matched moulds pressing and bending 90 °, to compensate bending springback capacity.For this reason, adjust the first wedge bar 12 to move horizontally drive second wedge bar 13 and move up and down, second wedge bar 13 acts on correction die 5 makes it move horizontally, and correcting punch 4 lower part also has inclined-plane to coordinate with correction die 5, also can reach the effect compensating bending springback capacity.The size compensating bending springback capacity decides the height of the second wedge bar 13 by adjustment first wedge bar 12, the height of the second wedge bar 13 determines the amount of moving horizontally correcting die 5, thus the size of control and regulation bending springback capacity.
The course of work of the present invention is as follows:
The first step, is positioned over workpiece 14 on die block 8, adjusts stamping position; Under the effect of punch press, upper die component band dynamic(al) correction punch 4 moves down, contact workpiece 14 material strip;
Second step, corrects punch 4 and makes workpiece 14 continue to move down when clamp with material lift block 7 acting in conjunction until contact and correct die 5, correction punch 4 with correct die 5 coordinate workpiece 14 upwards rolled over 90 ° curved;
3rd step, punch retainer 3 continues descending, adjust the bolt of the first wedge bar 12 end, first wedge bar 12 is moved inward, thus driving the second wedge bar 13 to move down, the second wedge bar 13 abuts the wedge-shaped indentation 503 correcting die 5 makes it inwardly move, and corrects the inclined-plane 501 on die 5 and corrects the common clamping work pieces 14 of punch 4 lower part, its bending is made to be less than 90 °, in order to compensate rebound amount.
Structure of the present invention is simple, handled easily, and cost is low, owing to being the workpiece that the male and female mold in normal bending gap is produced, effectively can reduce galled spots, and bending angle also can be up to standard, extend die life to a certain extent, reduce correcting process, enhance productivity; And after the wearing and tearing of correction punch and matrix Long-Time Service, the product size caused is changed the difference that is above standard and can be solved by inside adjustment the first wedge bar 12.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
