Изобретение относитс к устройствам дл подачи сварочной проволоки , преимущественно тонкой и м гкой , и может быть использовано в конструкци х сварочных полуавтоматов и автоматов как с плав щимс , так и неплав щимс электродом.The invention relates to devices for feeding welding wire, preferably thin and soft, and can be used in the construction of semi-automatic welding machines and automatic machines with both melting and non-melting electrodes.

В основном авт.св.. № 547309 otjHсан механизм подачи сварочной проволоки , используемый в сварочных полуавтоматах и автоматах 1 .Basically auth. Sh. № 547309 otjHsan welding wire feed mechanism used in semi-automatic welding machines and automatic machines 1.

Это устройство выполнено в виде корпуса, направл ющей, размещенных в ней захватов и кулачка, св занного с приводом.This device is made in the form of a body, a guide, housings and a cam associated with the actuator.

Недостатком этого механизма вл етс возможность образовани резкого перегиба подаваемой проволоки домика в районе подвижного захвата при внезапнь1х перегрузках, что приводит к нарушению подачи проволоки .The disadvantage of this mechanism is the possibility of a sharp bending of the feed wire of the house in the area of the moving grip during sudden overloads, which leads to a disruption of the wire feed.

Цель изобретени - повышение стабильности подачи проволоки путем обеспечени равномерности .подачи.The purpose of the invention is to increase the stability of the wire feed by ensuring uniform feed.

Это достигаетс тем, что ширина паза направл ющей равна толщине захвата , а угол наклона стенки паза, ограничивающей наклон захвата, составл ет 5-45 .This is achieved by the fact that the width of the groove of the guide is equal to the thickness of the grip, and the angle of inclination of the wall of the groove limiting the grip of the grip is 5-45.

На чертеже показано предлагаемое устройство, общий вид.The drawing shows the proposed device, the overall appearance.

Устройство дл подачи сварочной проволоки содержит корпус 1 с укрепленными в нем двигателем 2 вибратора , шлангом 3 со стопорным винтом 4 и захватом-стопором 5 с пружиной 6, направл ющую втулку 7, пружину 8, подвижную обойму 9 с установленными в ее пазу захватом 10, подаваемым сварочную проволоку 11 в направлении стрелки с помощью кулачка 12 вибратора.The welding wire feeder comprises a housing 1 with a vibrator motor 2 secured therein, a hose 3 with a locking screw 4 and a catch-stopper 5 with a spring 6, a guide bushing 7, a spring 8, a movable sleeve 9 with a gripper 10 installed in its groove, supplied by the welding wire 11 in the direction of the arrow using the cam 12 of the vibrator.

Устройство дл подачи сварочной проволоки работает следующим образом .,The device for feeding the welding wire works as follows.,

Claims

Vs1schal1 b1y engine 2 cam 12 presses on: the grip 10, which, jamming the welding wire 11, pressed against the inclined wall of the groove of the movable sleeve 9, feeds it forward in the direction of the arrow (compressing the spring 8) into the hose 3 held in the housing 1 locking screw 4. With further rotation of the cam 12, the gripper 10 is wedged, the spring 8 begins to expand and squeeze the movable sleeve 9 together with the gripper 10 from the guide sleeve 7. The movement of the welding wire 11 in the direction reversed is hampered by the gripper {POR 5 s spring 6, Formation in the housing 1. Thus, the welding wire is fed pulses. When seizure of the welding wire 11 by gripping Yu, the free reach of the wire is limited by the width — about the groove of the movable sleeve 9, which is equal to the thickness of the gripping plate 10, i.e. There is practically no free blasted out, moreover, the inclination of the gripper 10 is limited by the groove wall and is 5-45® (a larger angle is not advisable due to the excess of the bending force over the wire feeding force). Therefore, the bending of the supplied wire Sdomic cannot form. The tests carried out showed that the proposed device based on the DP-2-26 electric motor provides the supply of soft aluminum wire with a diameter of 1 mm with a force of 24 3.0-3.5 kg, and there were no cases of building houses in any feed modes. semi-auto- This type is cheap in I31 and provides high-quality welding. The invention The mechanism for filing the welding wire according to ed.St. No. 547309.0 tl and h and with the fact that, in order to increase the stability of the wire feed by ensuring uniform feeding, the width of the guide groove is equal to the gripping thickness, and the angle of inclination of the groove wall limiting the gripping inclination is 5- 45.
