Description
Technical field
The utility model relates to a kind of counnter attack rotational structure for rotating disk drawing die.
Background technology
Current rotating disk drawing die is mainly used for carrying out two times punch, but often easily there is despining phenomenon in the ratchet on rotating disk drawing die when rotated, this punching press meeting for drift has a huge impact, cause the defect rate of the drift after two times punch to improve, virtually increase the cost burden of enterprise, therefore, be necessary the rotating disk drawing die to improve to avoid occurring the despining of rotating disk.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of despun counnter attack rotational structure for rotating disk drawing die of rotating disk that prevents.
For achieving the above object, the utility model provides following technical scheme: a kind of counnter attack rotational structure for rotating disk drawing die, comprise rotating mechanism and the fixed mechanism that is located at rotating mechanism one side, described rotating mechanism comprises rotating shaft and is set in the rotating disk in rotating shaft, described rotating disk comprises spaced the first tooth, the second tooth and be arranged on the first tooth and the second tooth between groove, described fixed mechanism comprises shell, mounting blocks, arrange in the enclosure and the elastic component being fixedly connected with mounting blocks, described mounting blocks comprises the spur of protruding case surface, described groove is all suitable with spur shape, between described groove and spur, be provided with primary importance that spur is slidably matched with groove and spur and the groove second place being connected of conflicting.
By adopting technique scheme, when rotating disk clockwise rotates, in the time that the first tooth forwards the spur on fixed mechanism to, on rotating disk, the first inclined plane of groove and the second inclined plane of spur advance spur in shell after being slidably matched, in the time that rotating disk goes to next groove, owing to having cavity between groove and spur, elastic component rebounds afterwards and recovers elastic potential energy by compression, promote the spur of mounting blocks toward the motion of groove direction and protrusion case surface, when the second tooth contacts with spur, the tip of the second tooth is against on the second inclined plane of spur, because the angle of inclination on the second inclined plane is little, the second tooth and spur produce relative displacement and again spur are advanced in shell, the rest may be inferred, rotating disk circulation rotating like this, when rotating disk is rotated counterclockwise while being rotating disk generation despining, spur is protruded and is placed in groove, the second resistance surface of spur and the first resistance surface of groove are inconsistent, because the angle of inclination of the first resistance surface and the second resistance surface is large, between the first resistance surface and the second resistance surface, cannot carry out relative displacement, spur is firmly fixed and is placed in groove, rotating disk stops the rotation, and has effectively realized the despun effect of rotating disk that prevents.
The utility model is further set to: described groove is made up of the first inclined plane and the first resistance surface, described spur comprises the second inclined plane and the second resistance surface, between described the first inclined plane and the first resistance surface, be all angle setting between the second inclined plane and the second resistance surface, described the first inclined plane, the first tooth and the second tooth are all slidably matched with the second inclined plane, and described the first resistance surface is conflicted and is connected with the second resistance surface.
By adopting technique scheme, rotating disk clockwise rotates, on rotating disk, on the first inclined plane of groove and fixed mechanism there is being slidably matched of relative direction in the second inclined plane of spur, the effect on the first inclined plane of auxiliary pushing groove is played on the second inclined plane, exert all one's strength spur advanced in the shell of fixed mechanism in the first inclined plane of groove simultaneously, elastic component in shell is squeezed, elastic component drives the spur on mounting blocks to move toward the opposite side of relative rotating disk, makes the first tooth on rotating disk can without hindrancely pass through spur; In the time that dial rotation turns to the second tooth, elastic component bounce-back and the spur promoting on mounting blocks are moved toward rotating disk, spur is protruded case surface, the second inclined plane of spur is against on the tip of the second tooth, because the angle of inclination on the second inclined plane is little, make the second tooth and the second inclined plane that being slidably matched of relative displacement occur, again spur is advanced in shell; In the time that rotating disk is rotated counterclockwise, between the first resistance surface and the second resistance surface, cannot carry out relative displacement, thereby spur is stuck in groove, rotating disk cannot rotate, and has played the despining effect of rotating disk.
The utility model is further set to: on described rotating disk, be provided with through hole, described through-hole wall is provided with some grooves, is wholely set and equates with groove quantity and shape, all suitable lug bosses of size in described rotating shaft.
By adopting technique scheme, in rotating shaft, be provided with the lug boss of some quantity, lug boss in groove and the rotating shaft of the through hole on rotating disk carry out suitable after, increase the contact area of rotating disk and rotating shaft, rotating disk can be fixedly mounted in rotating shaft and ensure that the combination degree of rotating disk and rotating shaft is more firm, and rotating shaft drives rotating disk to be synchronized with the movement while rotation.
The utility model is further set to: the side at the corresponding spur of described shell place is circular-arc.
By adopting technique scheme, because rotating disk is rounded, on the circumferential outer surface of rotating disk, be wholely set the first tooth spaced apart and the second tooth, the first tooth and the second tooth even circumferential distribution winding are on rotating disk, and the outer ring that the first tooth and the second tooth surround is rounded, therefore the first tooth and the second tooth are all circular-arc, because the side at the corresponding spur of shell place is circular-arc setting and all suitable with the first tooth and the second tooth, when turntable rotation, the side at the corresponding spur of shell place is slidably matched with the first tooth and the second tooth respectively, the resistance that makes rotating disk turn over the first tooth and the second tooth reduces, increase work efficiency.
The utlity model has following advantage: the first inclined plane of groove and the second inclined plane of spur are slidably matched, the first resistance surface of groove and the second resistance surface of spur are inconsistent, and defining rotating disk can only single direction rotation, effectively prevents the despining of rotating disk.
