Abstract
The utility model discloses a flat knitting machine turned needle triangle. The turned needle triangle is of a left and right central symmetrical concave shape. An upper edge of the turned needle triangle is in an 'M' shape, and the turned needle triangle comprises two side faces and a concave face, wherein the two side faces are in a shape of concave in the lower portion and protruding in the upper portion. The needling surface is in arc connection and therefore the needling is smoother, and the angle of the needling surface is gradually reduced from 40 degrees to 33 degrees, and the two arcs are gently connected. A knitting needle is in gentle transition state while needling, and therefore a needle broken because of collision against the track and the like can be avoided.
Description
Technical field
The utility model belongs to the flat machine field of mechanical technique, and what especially relate to straight-bar machines turns over the pin triangle.
Background technology
Turning over the pin triangle is an important component part in the computer flat knitting machine head, and it mainly acts on is that the guiding knitting needle turns over the pin action.At present the knitting needle of computer flat knitting machine is not sufficiently oily owing to turn over the pin track when turning over the pin action, knitting needle easily and track bump, thereby the life-span of having reduced knitting needle also can be caused the decline of weaving quality.
Summary of the invention
The purpose of the utility model provides a kind of straight-bar machines and turns over the pin triangle, and it turns over the pin track can make that knitting needle is smooth and easy, is difficult for taking place the striker accident.
For this reason, the technical scheme that the utility model adopted is such: straight-bar machines turns over the pin triangle, it is characterized in that: turn over the pin triangle and be the centrosymmetric concave shape in the left and right sides; Its upper limb is " M " shape; Comprise two sides and a concave surface, two sides are the recessed prominent shape of, and circular arc connects between recess and the protuberance.
Further improvement as to the utility model is: the angle that said protuberance and horizontal plane form is from 40
0Reduce to 33 gradually
0
Further improvement as to the utility model is: the angle that said concave surface and horizontal plane form is 130
0
Further improvement as to the utility model is: the said pin triangle lower edge that turns over is the left and right sides centrosymmetric " M " shape; Said lower edge comprises two lower edge sides and emargination face once; Two lower edge sides are that a plane is connected with a curved surface circular arc; Said curved surface is the protruding down concavity of going up, and circular arc connects between protuberance and the recess, and said curved surface is connected with lower edge concave surface circular arc.
When Nose Left moved, minute hand epimere stitch mouth was positioned at the side bottom of turning over pin triangle left side, rose along " M " shape track, because the track of this track is circular-arc, knitting needle is difficult for bumping with track.When knitting needle runs to the top of track side surfaces, continue along downward circular arc descendingly then, because concave surface also is circular-arc here, and angle is the obtuse angle, so knitting needle will accomplish knocking over smoothly, turn over action such as pin, stitch continues descending along the another side of track afterwards.
Operation principle when Airplane Nose Right moves is identical when moving with Nose Left.
The utility model walk dial adopt circular arc to connect to make take the needle more smooth and easy; And walk the angle that reduces to 33 degree about dial is spent by 40 gradually; Connection between two sections circular arcs is mild; The knitting needle knitting needle is in mild transition state when taking the needle, can not occur bumping with track and situation such as broken needle occur.
In addition, the utility model lower edge protuberance is circular-arc the connection with recess, after knitting needle gets into this track, because track is in mild circular arc connection status, so also comparatively smooth and easy during the knitting needle walking.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the utility model track angle sketch map.
The specific embodiment
Referring to Fig. 1 and Fig. 2.Present embodiment comprises and turns over pin track 1, turns over pin track 1 and has left surface 11 and right flank, also has a concave surface 12.When knitting needle from e walking, the angle between e place and the horizontal plane is 40 to spend.The knitting needle continuation is up to along the d place gradually turns over o place, pin site, and at this moment the angle of left surface and horizontal plane reduces to 33 degree, and knitting needle gets into concave surface 12 subsequently, and the left surface of concave surface 12 and the angle of horizontal plane are 130 degree.Turn over the right side track and the left side symmetry of pin track 1, knitting needle turns over the pin action along final completion of cambered surface that above-mentioned circular arc connects.
The present embodiment lower edge hangs order track 2 for connecing pin, and the two sides that connect the pin track are that a plane is connected with a curved surface circular arc, and knitting needle slowly rises to gradually along this track and meets pin mark p place, because track is circular-arc for gently, the knitting needle smooth running the striker accident can not take place.
