Description

one

; The invention relates to the field of welding, ia specifically to welding equipment for: contact-arc welding of studs and similar products using flux or ceramic protective rings. It can be used in shipbuilding, mechanical engineering, construction and other industries.

Known pistol dl. welding of lumps, comprising a housing with a handle, bearing grip for studs, a stopper and an electromagnetic; Drive to pull off a stud from the product When installing a known pistol with a stud on the product, you need one ru | Koy to hold the pistol, and the second - the icTonopa button and when the it becomes flush with the supporting plane, raise the gun above the product in order to release the movable core from the stopper, and then proceed to reinstall the leaflet. These | Operators create the inconvenience of operation | and require an increased level from the {welder's side, since during re-installation, violation of welding gap gaps is possible: do slipped pins in the clamp. Pos2

Since the welder is forced to install the Sh1C tolet with two hands, it is difficult to weld the lags in the crowded places. Since the stationary and mobile core is located and is located with it in the JTO target, you first need to deactivate the attachment and then ITOK can be applied to the electromagnet for a stud. If the stopper for some reason does not have a mustache; Sings to go out of the groove of the core, the stopper in the core is stitched and B results in the pin freezing from the bottom of the core,

The disadvantage of the pistol is also the cost of setting up, measuring, and analyzing with & arch: azo | X) § .. The aim of the picture is to increase the use of wild pistols and reliability of work.

: For this, in the proposed gun, prk, the waters are made in the form of two s, aektromagings4 are installed one under the other with a space, a key, € on the outer sides of the last MHj kodo and the stopper is filled in through the electromagnet of the pulley passing through the hearthsl-sl.

l, fixed on the bark of the upper electromagnet with the ability to move

In addition to the convenience of setting and measuring and controlling the welding aasors of the Norn electromagnets, they are made with a cutout &

FIG. 1 shows a partially cut gun, a general view; in fig. 2 is a cross section of sub-D. in fig. one;

The device contains a composite case 1 with a handle, 2 for a stud 3 and an AJiyx tactical electromagnetic actuator consisting of windings 4 and 5j of Korya 6 and 7% of the completed plate, and the temperature of the Tactile 8. mounted. -, thread in the core 6, passing through fixed hearts Eikkk 9 and 10 and having a return point of 11 ,,

The anchor T through the rod 12 i is rigidly connected with the grip .2. and p1; p71 Ine: h in the direction of the product sedimentary npyjjviiHoil 13. To adjust the welding:, the grip 2 has a hook 14 to the gaps, To control the welding gaps, the distance between the pusher 8 and the bark 7; and the distance from the pusher Melsduard, 7 to 7 / Porn nut .15j km3 cut-out 13; -Column to core I, For the “iWTfaJ of the weld metal Lredkaziachepo flux ring 17, installed in the sleeve 18- The gun is operated by the legs (by 19,

Pistol for welding of the juvenile hoo-ybt as follows

When welding the gaps through hook 14 of grip 2, bring the bark 7 to the pusher 8. At the same time, the gap will be equal to the gap between the core 7 and the core lOj and the depth of the stud bj B welding BaiiHy (size value) the gap between the core 7 and the stop nut l5s Arc gap is adjusted by pushing the pusher 8 of the core 6 screwed in to the twisting, and the amount of draft is controlled by the enemy nut 15 in the appropriate direction. Welding gaps are controlled by a standard probe through the cutout 16 in the housing 1о

Woo Su 3 is installed in the gripper 2 and the cjaiiocoBOQ ring 17 is put on. When the gun is installed on the product, the spring 13 is first compressed until the measles 7 stop at the pusher 8 and then the stud 3 slides in the gripper until the stud ends coincide with the base surface of the sleeve 18.

When the button 19 is pressed, the welding voltage is applied to the stud 3, the winding 4 de-energizes, and the voltage is also applied to the winding 5. Anchor. 7 attracts and detaches the pin 3 from the product on the lead 4aHjr of this gap, and b under; The operation of the pusher 8 departs from the serie i eisffiKa 9 and compresses the spring 11. The arc burns on the arc, melts the end of the joystick 3, and welds the weld pool. After expiration of the set-j time of the ropeiraa arc, the winding 5 is removed, and a voltage is applied to the winding 4. Anchor 6, being attracted, acts | olkatep 8 on measles 7, and a stud under 1 / force of togzhatel 8 and two springs 11 and 13 is accelerated .. approaches the weld pool, and then when measles 6 is attracted to the core 9 slowly, ( only under the possibility of: de: |: st. thieves of deserts 13) is unloaded into a welded bath at a predetermined depth of sediment and is boiled "Then the cycle is repeated.
