CS225609B1 - Manufacturing process of the reinforcing of the openings in parts - Google Patents

Description

BACKGROUND OF THE INVENTION The present invention relates to a method of manufacturing a shoulder for reinforcing an aperture of a component, in particular a spacecraft, whose chamfer for supporting another component by means of a pin.

The reinforcement of the holes of some aoučáatí so is done by means of stiffeners that o cut out from sheet metal and weld aa to the body of the parts. Before přlvařenia it is necessary to align the metal reinforcement in the die on the liner.

The disadvantages of the existing method of stiffening a part hole are that the part is formed from two parts, of which several manufacturing operations are required to produce and weld the reinforcement - cutting from sheet metal, alignment in a die on the press - then welding to the body and drilling hole.

The above drawbacks eliminate the method of making a hole reinforcement shoulder and a part of the present invention, which consists in that the hole provided is stored by fixing the shelf and the lower die part of the first operation, after which the hole of the first operation is widened and forming the reinforcement flange at the next stage and and engaging the upper die part, the second calibration market operation creates a final calibrated reinforcement flange formation with a calibrated opening.

Advantages of the method of fitting for part opening reinforcements are that the reinforcement part is formed from a single part by two manufacturing operations. Material savings are achieved by reducing the number of production operations, thus achieving increased labor productivity and savings in electrical energy by completing welding.

The sequence of operations in the production of the step for reinforcement of the eeučáati etver is illustrated in the drawing, where ebr. 1 depicts a starting plow of the bed of the eucalyptus pad and and the drop part of the first eperaco, ebr. 2 creates a reinforcing collar with sludge and abr. 3 shows the final calibrated shape of the reinforcing collar and the calibrated ether.

The pouch 1 and the ether 2 will provide the de-sealing tabs of the lower part 2 of the die of the first eperation. Treatment mandrel 2 £ gaming piece die first eperaoa aa converts expansion aperture 7 eeučáati 1 and thus creates aa aaučasně vyztužavací lam 12 Kelem opening 7. During the return movement of the game piece · £ die first operation aaučáat 1 remains attached to the mandrel 2 · ^e * In the longer phase aa and aaučáat 1, a second eperaoa is placed on the insertion plate 2 and on the part 2 of the die. By engaging the die part 10 of the second eperation and the calibrating mandrel 8, it forms the final calibrated shape of the rim 12 and the calibrated ether 7. Upon returning the die part 10, the second aperaea remains behind the calibration track 8 and wiped off by the wiper 11.

A method for producing a stiffener for reinforcing an asteroid and a die, in particular a component having an aperture therein to accommodate further aeroid through a pin, characterized in that the etered component is placed in a sealing bead on the lower die part of the first operation. it will widen the hole and at the same time create the reinforcing collar and in the next stage and by acting of the play part of the second operation die and the calibration mandrel it will create a cannulating calibration shape of the reinforcing collar and calibrated ether.
