Description
Technical field
The present invention relates to steel ring manufacture field, particularly driving steel ring rounding device.
Background technology
The motor vehicle of many such as trucks, minibus and so on generally adopts tubeless tyre, is commonly called as vacuum tyre.Tubeless tyre is similar to conventional tyre in appearance, difference be tubeless tyre cover tire inwall on addition of thick layer about 2 ~ 3mm be used for specially seal the rubber sealant of gas, it adheres to by the method for sulfuration, below the tyre surface that sealant faces, the self-adhesive layer that the special mixture that against one deck half finished rubber is made.When puncture of tire, the hole that self-adhesive layer can be about to pierce through certainly bonds, the tubeless tyre of the self-adhesive layer that is therefore otherwise known as.Tubeless tyre is when boring a hole, pressure can not sharply decline, and be conducive to safety traffic, tubeless tyre does not exist the abrasion between Tire & Tube and blocks, its air-tightness is good, directly can be dispelled the heat by wheel rim, temperature rise is low, long service life, structure are simple, lightweight.But because tubeless tyre jointly forms gas storage space with Automobile steel ring wheel rim, the complete totally enclosed inner tube of a tyre of neither one is as interior reservoir headroom, if therefore Automobile steel ring wheel rim has the defect such as crack, holes to cause a flat tire, major hidden danger is caused to traffic safety.
Generally adopts thickness is at present that the rectangular hot rolled steel plate of more than 5 millimeters encloses and justifies equipment circle and become circular arc, again two far-ends are manufactured Automobile steel ring by the production technology that rolling technology is shaped after being welded into annulus, and in volume annulus joint, the circular arc degree of steel plate is inadequate, need to carry out full circle to steel plate, then existing rounding device needs to stir steel ring rotation by hand, and operating efficiency is lower.
Summary of the invention
The object of this invention is to provide driving steel ring rounding device, automatically full circle is carried out to steel ring, thus increase work efficiency.
The invention provides a kind of base case: driving steel ring rounding device, comprise frame, casing is fixedly installed above frame, counterdie is fixedly installed above frame, the upper surface of counterdie is the circular arc matched with steel ring, the patrix matched with counterdie is provided with in casing, the upper surface of casing is provided with the drift driving patrix to move up and down, upper die and lower die give prominence to a horizontal plane part for frame, patrix is to being outside equipped with fixed axis, vertical catch bar is provided with above fixed axis, counterdie is to being outside equipped with turning cylinder, turning cylinder is parallel with fixed axis, the center of circle of turning cylinder is departed from the end of catch bar, multiple support bar has been disposed radially above turning cylinder, the end of support bar is provided with pushing block.
Operation principle and beneficial effect are: adopt the lower surface of patrix to match with the upper surface of counterdie in the present invention, be the circular arc of fitting with steel ring, when like this steel ring being placed on counterdie upper surface, patrix moves up and down and can carry out full circle to the local circular arc of steel ring, makes it identical with the circular arc degree of standard steel ring.Then be enclosed within the end face of counterdie by the part that steel ring gives prominence to frame along counterdie, the local circular arc of steel ring and the upper surface of counterdie fit, and the pushing block above support bar contacts with the inwall of steel ring.When drift moves downward time, the ends contact of catch bar is to the sidewall of turning cylinder, and catch bar promotes turning cylinder and rotates, thus drives steel ring to rotate.When drift moves upward, catch bar departs from the surface of turning cylinder, and steel ring keeps motionless.
The present invention adopts upper and lower mould cooperation to carry out full circle to steel ring, and make it identical with the circular arc degree of standard steel ring, structure is simple, and application condition is little, and full circle is effective.Simultaneously, utilize moving up and down of upper and lower mould, tangent by the sloped sidewall of catch bar and turning cylinder, catch bar can promote turning cylinder and rotate, simultaneously, because support bar and pushing block are for supporting steel ring, so steel ring rotates along with the rotation of turning cylinder, structure is simple, and can automatically make steel ring rotate, eliminate people and stir steel ring with hand, high safety.
Further prioritization scheme one for base case: drift and cylinders.Because drift drives patrix to move up and down,
For this reason, arrange cylinder and be connected with drift, can promote drift by the piston rod of cylinder, provide power source to drift, and the regularity that moves up and down of cylinder is stronger, movement velocity is even.
Further prioritization scheme two for base case: upper die and lower die adopt 12Cr2Ni4A Steel material to make, and this Steel material plasticity is strong, and morphotropism is low, and case hardness is high.
Further prioritization scheme three for base case: the quantity of support bar is three.Because support bar is mainly used in supporting steel ring, and three form a face, so the quantity arranging support bar is three.
Further prioritization scheme four for base case: support bar is radially uniformly distributed, ensures the uniform force of support bar like this, prevents local support bar stressed excessive and damage.
Further prioritization scheme five for base case: pushing block is semicircle, is convenient to fit with the inwall of steel ring, and support effect is better, can not scratch steel ring inwall simultaneously.
