utility model content:
The purpose of this utility model is exactly the deficiency existing for prior art and provide that a kind of serviceability is stable, ABRASION RESISTANCE is high, cost is low, assemble selection piece easy to process.
To achieve these goals, the technical solution adopted in the utility model is:
Selection piece, includes metal needle selection cutter head, plastic cement encapsulate skeleton, and needle selection cutter head is covered by formation damascene structures in encapsulate skeleton.
Described encapsulate skeleton is combined into one by integrated injection molding mode and needle selection cutter head.
Described encapsulate skeleton bottom forms drive division, and in drive division, edge laterally offers pin hole.
Also can be, described encapsulate skeleton bottom forms drive division, the laterally chimeric pivot pin that is fixed with of edge in drive division.
The drive division of described encapsulate skeleton bottom convexes to form forward d character form structure.
Described drive division bottom convexes with boss, and boss bottom offers magnet steel hole, and magnet steel is fixed with magnet in hole.
The material of described needle selection cutter head is high speed steel material.
The thickness at the middle part of described needle selection cutter head is compared with the thin thickness on both sides, and the middle part of needle selection cutter head offers the long slot bore of injecting hole and strip.
The middle part of described needle selection cutter head offers groove, and injecting hole and long slot bore are arranged in groove.
The head of described needle selection cutter head is the triangular structure that both sides have gradient, and the angle of the head of needle selection cutter head is 90 ~ 130 degree.
The utility model beneficial effect is: the utility model includes metal needle selection cutter head, plastic cement encapsulate skeleton, needle selection cutter head is covered by formation damascene structures in encapsulate skeleton, wherein needle selection cutter head adopts the good metal material of ABRASION RESISTANCE, encapsulate skeleton adopts the plastic material of good toughness, needle selection cutter head and encapsulate skeleton are entrenched togather and form well-set assembly, both there is ABRASION RESISTANCE and the stability of metal material, there is again the toughness of plastic material, can under high pressure conditions, realize high-frequency, high load capacity, operate at high speeds, serviceability is stable, ABRASION RESISTANCE is good, simple and reasonable, cost is low, assemble easy to process.

detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further described, sees shown in Fig. 1 ~ 5, selection piece, includes metal needle selection cutter head 1, plastic cement encapsulate skeleton 2, and needle selection cutter head 1 is covered by the interior formation damascene structures of encapsulate skeleton 2.Encapsulate skeleton 2 is combined into one by integrated injection molding mode and needle selection cutter head 1, and the metallicity of needle selection cutter head 1 and the plastic cement performance of encapsulate skeleton 2 can be combined better, improves combination property.
The material of needle selection cutter head 1 is high speed steel material, and high speed steel material ABRASION RESISTANCE is fabulous, hardness is high, has greatly strengthened the ABRASION RESISTANCE of selection piece, and encapsulate skeleton 2 adopts plasticity, toughness, intensity, ABRASION RESISTANCE etc. to require high plastic material.Needle selection cutter head 1 global shape is irregular or regular rectangle, the thickness at the middle part of needle selection cutter head 1 is compared with the thin thickness on both sides, the middle part of needle selection cutter head 1 offers the long slot bore 12 of injecting hole 11 and strip, injecting hole 11 has multiple, be distributed in around long slot bore 12, strengthen the firm degree of combination between encapsulate skeleton 2 and needle selection cutter head 1, more effectively prevent that encapsulate skeleton 2 from departing from.Wherein, the middle part of needle selection cutter head 1 rear and front end face all offers groove 13, and groove 13 makes needle selection cutter head 1 shape that is entrenched togather more firmly, and injecting hole 11 and long slot bore 12 are arranged in groove 13.The shape of the shape of needle selection cutter head 1 bottom, the shape of groove 13 and injecting hole 11 can be rule or irregular shape.Needle selection cutter head bottom extends downward in drive division 21, strengthens the bulk strength of selection piece, is distributed with 11 and 2 long slot bores 12 of 6 injecting holes on groove 13.
The head of needle selection cutter head 1 is the triangular structure that both sides have gradient, the angle of the head of needle selection cutter head 1 is 90 ~ 130 degree, as 90 degree, 100 degree, 120 degree, 130 degree etc., it can certainly be other angle, head angle and long slot bore 12 by reasonable disposition needle selection cutter head 1 arrange, and have effectively improved movement velocity and the needle selection efficiency of selection piece.
When use, put on pivot pin at pin hole 22, by pivot pin, selection piece is positioned on needle selector frame, the magnet 3 by the coil on slide cam selector and selection piece lower end is by swing and the reset of control system of switching on or off electricity selection piece, thereby realizes needle selecting function.The utility model needle selection cutter head 1 adopts the metal material that ABRASION RESISTANCE is good, encapsulate skeleton 2 adopts the plastic material of good toughness, needle selection cutter head 1 is entrenched togather and forms well-set assembly with encapsulate skeleton 2, has both had ABRASION RESISTANCE and the stability of metal material, has again the toughness of plastic material, can under high pressure conditions, realize high-frequency, high load capacity, operate at high speeds, serviceability is stable, and ABRASION RESISTANCE is good, simple and reasonable, cost is low, assembles easy to process.
As the second embodiment of the present utility model, see shown in Fig. 6 ~ 7, different from the first embodiment is, the laterally chimeric pivot pin 4 that is fixed with of edge in drive division 21, selection piece can be positioned on needle selector frame by pivot pin 4, selection piece can be swung, easy to install and use.Encapsulate skeleton 2 is combined into one by integrated injection molding mode and pivot pin 4, and the metallicity of pivot pin 4 and the plastic cement performance of encapsulate skeleton 2 can be combined better, improves combination property.
