SU127777A1 - Head for welding with electric rivets - Google Patents

Description

The present invention relates to welding heads for welding flux electro-glucose stones. Known holoscans of this kind, which contain a disconnected feed mechanism isolated from the oHopuyii crown, a pneumatic or a mechanic KKI-LH drive for creating pressure on an internal current supply piece to the product, do not provide convenient simultaneous use; multi-electrode welding.

In order to eliminate this drawback, it is proposed to supply the electrode with a friction hinge grip that is found under the action of two, one of which, more force, is connected to the drive and mixes the grip with the electrode to the product, and the second is connected to the head cornus and moves gripping in position after co-pinning of the electrode with the product and pacKoiiiTnM gripping.

In order to create a gap between the electric motor and the welding rod and the new welding quality, the current lead pip mouthpiece is fixed between the lugs in the head housing with a spring washer, which ensures the current supply with the electrode after opening of the gripper.

FIG. 1, 2, 3, and 4 are diagrams of the proposed heading, explaining its structure and operation.

The head (one or several) is fixed on the clamping cross member / with the help of a nut on the brush 2. In the case of 3 heads, a powerful spring 4, a housing .5 of a three-blade grip for the electrode, a senator 6 and balls 7 are springed. Springs 8 ii-9 serve for interleaver 11 of the housing 5. The conductive die 10 is iodized by the action of a rotary socket // lying on the insulating collar 12, which insulates the packer 13 from the housing. Electrode 14 fits tightly into the mouthpiece 10. The diagram below shows four consecutive positions of the p-shaped slide parts of the head during its operation.

NO 127777-2 -

When lowering the crosshead 1 with the head down, the tip 13 is aligned with the product (position /), the stem 2 is operated, and through the spring 4 moves down the body 5 of the friction 1-grip gripper. The electrode is wedged and fed down to the stop with the product (according to // //). The mouthpiece 10 under the action of friction with the electrode also starts and compresses the washer. When moving downwardly, the pickup body 5 rests against the head body 3 (position ///), and the moving rod 2 releases the pickup electrode by pressing on the separator 6. Under the action of the washer, the mouthpiece with the electrode rises up, forming a gap between the electrode and the to be. which is necessary for normal ignition of the welding arc (position / V). In this position, after the flux is supplied, the arc is ignited and welding is performed. The arc burns to a natural cliff. After iodine traverse up, the head takes the starting position.

The described head can work from an individual drive, as well as by moving the crosshead, on which several heads can be fixed.

PREPARATION AND RESULTS

1. A head for flux welding with a flux node containing a support tip insulated from the housing, an intermittent electrode feeding mechanism, a pneumatic or mechanical actuator to co-ordinate pressure on the product and a mouthpiece to supply current to the product. that, in order to simplify the simultaneous use of several heads during multi-electrode welding and to stabilize the welding quality, the EoTelectrode feed mechanism contains a friction spherical gripper for mixing the electrode, which is under the action of two Ruzhin, one of which is stronger bonded to the actuator and moves the engagement with the electrode with the workpiece, and the second is associated with the head body and grip moves to its original position after kosioveni conjugated with the workpiece and gripping disclosure.

2. The heading for and. 1, characterized in that, in order to create a fixed gap between the electrode and the product before welding and improve the quality of welding, the current-carrying mouthpiece is fixed between the unors in the head housing with a spring washer, which ensures the current lead with the electrode to rise after opening.
