Abstract
The utility model discloses a needle guard cam for a flat knitting machine. The needle guard cam is horizontally and centrally symmetric, the lower edge of the needle guard can is in an M shape, the needle guard cam comprises a left-right lateral face and a concave face, the left-right lateral face comprises a beginning section, a parallel section and a rising section, the beginning section is bent downwards to be connected with the parallel section in an arc mode, and the parallel section is in arc connection with the rising section. The needle guard cam has the advantages that the lower edge of the needle guard can is in gentle arc design so as to enable needles to run stably and slowing, and the needles and the cam are not prone to be damaged.
Description
Technical field
The utility model relates to the flat machine field of mechanical technique, especially relates to straight-bar machines and protects the pin triangle.
Background technology
Straight-bar machines to turn over that the pin triangle mainly acts on be that the guiding knitting needle turns over pin action, be to be used for cooperating turning over the pin triangle and being well on and turning over pin and protect the pin triangle.When knitting needle turns over pin, protect the pin triangle and can prevent that knitting needle from departing from and turn over the pin track.Use at present protect the pin triangle and to turn over the track that the pin triangle cooperates mild inadequately, knitting needle easily and the track that protects on the pin triangle bumps, thereby cause the knitting needle damage.
Summary of the invention
The purpose of the utility model provides a kind of straight-bar machines and protects the pin triangle, can protect trigonometric sum knitting needle pin bell, is difficult for when operation, breaking down.
For this reason, the technical scheme that the utility model adopted is such: straight-bar machines protects the pin triangle, it is characterized in that: protect center, pin triangle left and right sides symmetry; Its lower edge is " M " shape, comprises a left and right side and a concave surface, and the left and right side comprises The initial segment; Parallel-segment and ascent stage; Said The initial segment downwarping is connected with the parallel-segment circular arc, and parallel-segment is connected with the ascent stage arc.
Further improvement as the utility model is: the ascent stage of said lower edge two sides and the angle of horizontal plane are from 40
0Reduce to 35 gradually
0
The utility model center symmetry is fixed on the triangle motherboard through pin and screw.After knitting needle got into and turns over the pin track, the utility model matched with turning over the pin triangle, made knitting needle in the orbit space that both form, move; Knitting needle can arrive the ascent stage along the The initial segment of protecting the pin triangle, parallel-segment; Because the ascent stage is a slow arcwall face that changes, the angle of its arc and horizontal plane reduces to 35 degree from 40 degree gradually, and this structure makes knitting needle milder; Be difficult for and protect the pin triangle bumping, be easy to protect trigonometric sum knitting needle pin bell.Walk out when turning over the pin track when knitting needle, knitting needle is convenient in the reclinate arc design of protecting the track The initial segment of pin triangle, and to go out pin smooth and easy.
The beneficial effect of the utility model is: the mild arc design of protecting the pin track makes that the knitting needle operation is mild, not fragile knitting needle and triangle.
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 lower edge angle sketch map.
The specific embodiment
Referring to Fig. 1 and Fig. 2.Present embodiment protects pin triangle 1 and has lower edge, and its The initial segment a is reclinate arc, follows to be connected with ascent stage c arc by parallel-segment b; Form the obtuse angle between the two, the initiating terminal of ascent stage c and horizontal plane form the angle of 40 degree, and ascent stage c is irregular arcwall face; The terminal of ascent stage c and horizontal plane form 35 degree angles; Knitting needle arrives when turning over pin mark o, continues to walk out gradually then and turn over the pin track along the bottom e of the descending arrival concave surface of side d of circular arc concave surface.
Claims (2)
1. straight-bar machines protects the pin triangle, it is characterized in that: protect center, pin triangle left and right sides symmetry, its lower edge is " M " shape; Comprise a left and right side and a concave surface, the left and right side comprises The initial segment, parallel-segment and ascent stage; Said The initial segment downwarping is connected with the parallel-segment circular arc, and parallel-segment is connected with the ascent stage arc.
2. straight-bar machines as claimed in claim 1 protects the pin triangle, it is characterized in that: the ascent stage of said lower edge two sides and the angle of horizontal plane are from 40
