Abstract
The utility model belongs to the technical field of drive mechanism, especially, relate to an improve plate shearing machine cam, including rim plate, through -hole and fixed orifices, be equipped with the through -hole on the rim plate, the through -hole is equipped with a plurality of fixed orificess all around, the continuous curved surface of enclosed type that the profile face of rim plate comprises end to end's first segmental arc, second segmental arc, third segmental arc, fourth segmental arc and the 5th segmental arc in proper order. The curvature radius of first segmental arc is 98mm -99mm, and the curvature radius of second segmental arc is 128mm -129mm, and the curvature radius of third segmental arc is 30mm -31mm, and the curvature radius of fourth segmental arc is 176mm -177mm, and the curvature radius of the 5th segmental arc is 90mm -91mm. The through -hole is completely circular shape, and the radius of through -hole is 20mm -22mm. The fixed orifices is the arc hole, is equipped with 3 fixed orificess on the rim plate, and the fixed orifices evenly sets up around the through -hole. By adopting the above technical scheme for the plate shearing machine cam is more durable, and motion laws is stable, the phenomenon of plate shearing machine cam can not appear often changing, has improved work efficiency when having saved manufacturing cost.
Description
Technical field
The utility model belongs to driving mechanism technical field, especially relates to a kind of improvement guillotine shear cam.
Background technique
Guillotine shear equipment to use cam and carry out transmission, loss can be caused to cam in transmission process, in existing technology, guillotine shear cam structure is too simple, in use often cause durability low, need often to change cam, cause inefficiency, be adopt groove to be fixed on fixing, so unstable problem greatly also there will be to element consume degree.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of efficient stable and durable guillotine shear cam, is especially applicable to the technological process that needs use guillotine shear continuously.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of improvement guillotine shear cam, comprise wheel disc, through hole and fixed hole, wheel disc is provided with through hole, and through hole surrounding is provided with multiple fixed hole, the enclosed type continuous curve surface that the contoured surface of wheel disc is made up of end to end first segmental arc, the second segmental arc, the 3rd segmental arc, the 4th segmental arc and the 5th segmental arc successively.The radius of curvature of the first segmental arc is 98mm-99mm, and the radius of curvature of the second segmental arc is 128mm-129mm, and the radius of curvature of the 3rd segmental arc is 30mm-31mm, and the radius of curvature of the 4th segmental arc is 176mm-177mm, and the radius of curvature of the 5th segmental arc is 90mm-91mm.Through hole is positive circular, and the radius of through hole is 20mm-22mm.Fixed hole is arcuate socket, and wheel disc is provided with 3 fixed holes, and fixed hole is evenly arranged on through hole surrounding.
The advantage that the utility model has and good effect are: owing to adopting technique scheme, make guillotine shear cam more durable, and the characteristics of motion is stablized, there will not be the phenomenon often changing guillotine shear cam, while saving cost of production, improve working efficiency.
