Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
With reference to Fig. 1, shown in Fig. 2 and Fig. 3, a kind of band inclined plane drawing die, comprise upper bolster 2 and the die shoe 8 of corresponding setting, described upper bolster 2 lower surface is provided with punch fixed block 3, oblique spring bearer plate 5 is provided with immediately below described punch fixed block 3, spring 16 is provided with in the middle of described oblique spring bearer plate 5 and punch fixed block 3, described punch fixed block 3 lower surface is fixed with punch 14, described die shoe 8 upper surface is provided with the oblique die 7 corresponding with described punch 14, the upper surface of described oblique die 7 is fixed with locating piece 12, described die shoe 8 lower surface center is provided with Lifting Device.
Described upper bolster 2 upper surface center is provided with die shank 1, described upper bolster 2 lower surface is provided with guide pin bushing 4 near four corner positions, described die shoe 8 upper surface is provided with the guide pillar 6 corresponding with described guide pin bushing 4, by the guiding that cooperatively interacts of guide pin bushing 4 and guide pillar 6, the cooperation of punch 14 and oblique die 7 can be ensured more accurately, improve the quality of tensioning member further.
Described oblique spring bearer plate 5 is consistent with oblique die 7 horizontal gradient, the plate uniform force being placed on oblique die 7 upper surface can be made like this, also can well ensure that tensioning member inclined-plane is in same plane, the cooperation of tensioning member and other part can well be ensured, improve the qualification rate on tensioning member inclined-plane.
Described oblique spring bearer plate 5 has stay bolt 15 and lag bolt 17 to be fixed on immediately below punch retainer 3, because oblique spring bearer plate 5 lower surface and horizontal plane are 10-30 degree, so tiltedly the variable thickness of spring bearer plate 5 causes, and then bolt 15 length of fixing oblique spring bearer plate is just different, so fix oblique spring bearer plate 5 below punch retainer 3 with 2 stay bolts and 2 lag bolts.
Described oblique spring bearer plate 5 stay bolt 15 and lag bolt 17 are fixed on immediately below punch retainer 3, but spring 16 is also provided with in the middle of oblique spring bearer plate 5 and punch retainer 3, material pressing device thus, can prevent the stretching sheet material problem that the depth of parallelism on tension failure and tensioning member inclined-plane is bad because pressure is too large in the process stretched very well.
Described punch 14 is fixed on punch fixed block 3 lower surface, and through oblique spring bearer plate 5, and then punch 14 receives the protection of oblique spring bearer plate 5, avoids that punch 14 is exposed to be collided outside and to wear and tear, and fully ensure that the stretching quality of tensioning member.
Described Lifting Device is made up of elastic washer 9 and ejector beam 10, and described ejector beam 10 is fixed on elastic washer 9 upper surface center, and through die shoe 8 and die 7, this device effectively raises pickup efficiency, further increases production efficiency.
Beneficial effect of the present invention in sum, a kind of band inclined plane drawing die, this drawing die is designed with the oblique spring bearer plate of a flexible function, this spring bearer plate with bolt fixing with punch retainer immediately below, spring is provided with in the middle of oblique spring bearer plate and punch retainer, when oblique spring bearer plate encounters the plate being placed on molding surface, spring bearer plate applies certain power to plate under the action of the spring, load pressure is not very large, bevelled tensioning member simultaneously under the cooperation of punch and oblique die required for stretched consumer, due to the oblique elastic material plate that this drawing die designs, so decrease tension failure and the bad problem of inclined-plane tensioning member flatness.And then advantage of the present invention is; Reasonable in design, structure simply, effectively prevents tensioning member fracture, improves the inclined-plane depth of parallelism of tensioning member, is convenient to promote.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
