Abstract
The utility model discloses a wire feed rolls for MIG welds thread feeding mechanism, including the wire feed rolls body, the circular external diameter uniform distribution of body have a plurality of straight -tooth that set up along the body axial. The utility model has the beneficial effects of, carrying the welding wire in -process, taking turns at the silk pressing under the straight -toothed effect on body surface with one side aluminium welding wire surface of wire feed rolls contact, extruded the even orderly recess of shallow one deck, a whole process of sending is just god forward like same tooth wheel rotating band carry -over bar, and fundamentally has solved the problem that the welding wire skidded, can be applicable to the aluminium welding wire of different diameters, needn't change the wire feed rolls again during the change welding wire.
Description
Technical field
The utility model relates to a kind of wire feed rolls of wire-feed motor, is specifically related to a kind of wire feed rolls welding wire feeder for MIG.
Background technology
At present when MIG aluminium welding wire welds, because aluminium welding wire is softer, sending to for ensureing that its welding wire can be stablized, just having higher requirement to wire feeder.Wire feeder is made up of motor, bracket, silk pressing adjusting device, thread pressing wheel, wire leading pipe and wire feed rolls etc. usually.Wherein the effect of wire feed rolls is that welding wire is delivered to arc region by wire convey soft pipe uniformly and stably, and the pressure of combination to welding wire of the wire feed rolls of various different surfaces shape is different.Wherein, U-type groove wire feed rolls due to the contact area with welding wire comparatively large, comparatively even to the pressure ratio of welding wire, apply more general when aluminium welding wire weld.But U-type groove wire feed rolls in use also comes with some shortcomings, time as larger in wire-feeder resistance, there is the situation that wire feed rolls skids.
Utility model content
For the above-mentioned defect existed in prior art and deficiency, the utility model provides a kind of wire feed rolls welding wire feeder for MIG.
The utility model is achieved by the following technical solution: a kind of wire feed rolls welding wire feeder for MIG, comprises wire feed rolls body, it is characterized in that, the circular outer diameter surface uniform of described body is distributed with some along body shaft to the straight-tooth arranged.
One end of described wire feed rolls body is provided with hexagonal (hexagon)nut, and the other end is provided with packing ring.
Described wire feed rolls entirety is one-body molded.
Usefulness of the present utility model is, in conveying welding wire process, the aluminium welding wire surface, side contacted with wire feed rolls is under the effect of the straight-tooth on thread pressing wheel surface, be squeezed out the groove that simple one deck is evenly neat, whole wire feed process just rotarily drives tooth bar as gear and advances, fundamentally solve the problem that welding wire skids, go for the aluminium welding wire of different-diameter, when changing welding wire, wire feed rolls need not be changed again.

Fig. 1 is front view of the present utility model;
Fig. 2 is the sectional view of Fig. 1;
Fig. 3 is top view of the present utility model;
In figure, 1, body, 2, hexagonal (hexagon)nut, 3, packing ring, 4, straight-tooth.
Detailed description of the invention
Below by non-limiting embodiment and by reference to the accompanying drawings to utility model further instruction:
As shown in drawings, a kind of wire feed rolls welding wire feeder for MIG, comprises wire feed rolls body 1, and the circular outer diameter surface uniform of body 1 is distributed with some along body shaft to the straight-tooth 4 arranged.One end of body 1 is provided with hexagonal (hexagon)nut 2, wire feed rolls for convenience detach, and the other end of body 1 is provided with packing ring 3.
Described wire feed rolls entirety is one-body molded.
In conveying welding wire process, the aluminium welding wire surface, side contacted with wire feed rolls body 1 is under the effect of the straight-tooth 4 on wire feed rolls body 1 surface, be squeezed out the groove that simple one deck is evenly neat, whole wire feed process just rotarily drives tooth bar as gear and advances, wire-feeder resistance is little, go for the aluminium welding wire of different-diameter, the problem may skidded when efficiently solving conveying aluminum welding wire, and wire feed rolls need not be changed again when changing welding wire.
Claims (3)
1. weld a wire feed rolls for wire feeder for MIG, comprise wire feed rolls body, it is characterized in that, the circular outer diameter surface uniform of described body is distributed with some along body shaft to the straight-tooth arranged.
