Description
Technical Field
The invention relates to a needle groove processing method of a full-ready-made-garment four-needle-bed computerized flat knitting machine.
Background
A computer flat knitting machine main closed needle bed in the knitting machinery industry is made of 45# medium carbon structural steel or steel materials close to the mechanical and processing performances of the medium carbon structural steel, insert grooves with the overall dimensions of 40-80 inches and with the lengths of 1310-2330 mm, the widths of 230 mm and 11 mm are densely distributed on the 230 mm wide surface 720(40 inches) -1440 (80 inches) strips with the widths of 0.8-2.00 mm and the depths of 5 mm are installed according to the used needles and different needle pitches, insert sheets for combining needle grooves are formed, the requirements of the width of the formed needle grooves and the tolerance of adjacent groove pitches are quite high, accumulated errors of the total width dimensions of hundreds of thousands of needle grooves are less than or equal to 0.05 of the needle pitch 16, the symmetry degrees of needle grooves of front and rear needle beds are less than or equal to 0.03, the straightness degrees of knitting openings of the front and rear needle beds are less than or equal to 0.03, otherwise, cashmere sweater knitted by raw materials of millions of one ton loses serious flatness and loses serious deformation after water washing, irregular needle selection and the accumulated errors of the total needle grooves and the overlong needle grooves and the accumulated errors cause serious collision of a computer flat knitting machine head collision to a Accidents and other problems are caused because the most basic data of the system is that the number of the needles of the fabric to be knitted and the needle positions of the pattern organization of the cloth cover are obtained from the needle position of the needle bed from the initial needle position to the last needle position by 'a plurality of needles'.
The development of a computerized flat knitting machine for more than ten years is mass production (all the past is imported from developed countries), the development of the computerized flat knitting machine is restricted by the quality of a needle bed, and the great reason is that although a special numerical control needle slot milling machine is adopted for processing a plug slot, a processing mode for processing a small needle plate needle slot of a hand flat knitting machine is adopted, namely, a plurality of milling cutters are stacked and serially arranged on the same cutter shaft by using separating sheets, 3-18 (6 or 9 are also arranged for 16-18 half-inch 12.7 mm), a high-speed steel or hard alloy saw blade type cutter with the thickness of 0.80-2.00 mm and the outer diameter of 85-90 mm is provided with sparse teeth or dense teeth, a shaft hole adopts phi 27.00-32.00 mm according to the depth of the needle slot, although the separating sheets are precisely ground to control the flatness in micron mu level, and are smooth, and have auxiliary deflection angles on two sides of a cutting blade, a plane table is arranged near the shaft hole, but a plurality of stacked plates still generate larger accumulated error, after fastening, the main shaft generates radial run-out, the parting sheet is locally painted and corrected or a customized metal foil is adopted for correcting a certain error amount, but the errors of the groove width and the adjacent groove distance cannot be fundamentally solved, the blade is repeatedly grinded, even though the blade is clamped according to the original blade sequence and the tooth position of the blade, the depth difference of the inserting sheet groove caused by the outer warp error cannot be avoided, only the needle bed restricts the level of the domestic computerized flat knitting machine to stay at the middle bottom level, and the development of the four-needle bed computerized flat knitting machine for once weaving the fine-gauge ready-made clothes is further restricted.
A fine-gauge four-needle-bed computerized flat knitting machine for one-off ready-made clothes knitting adopts a composite needle bed, referring to figure 4, when a machine head moves leftwards, a front lower needle bed and a back upper needle bed knit a front body, a cuff and a front body lower hem thread (needle separating knitting, lower knitting and the same), when the machine head moves rightwards, the back lower needle bed and the front upper needle bed knit a back body, the cuff and a back body lower hem thread, a front needle bed and a back needle bed can knit a flat needle according to the lower front needle bed and a back needle bed, the front needle bed and the back needle bed can also mutually shift a connecting ring (inverted needle) to knit a withdrawing needle, a hole picking, a half-stitch, a hank flower, a three-dimensional 3D and other flower-shaped fabrics, a back top small needle bed bears a pressing line and can be deep and shallow according to the knitting condition, taking a 16-needle 60-inch ready-made clothes knitting machine as an example, the reciprocating speed of the machine head is 1.2 meters/second, 4800 knitting needles can finish the knitting of, the key is that the accurate matching with the knitting needle and the high-precision mutual symmetry of the needle grooves are realized by the needle tracks of the 4 needle beds. The only fine-gauge machine in the world is widely accepted by the sweater industry in China at a unit price of 130 ten thousand (tax completion) (in 2019, the home-made two-needle bed coarse-gauge needle-separated ready-to-wear computer with two needle beds is only about 15 thousand) and meanwhile, the independent research and development and volume production of the domestic knitting machine industry are called for.
In the existing special needle slot milling machine, a power box body (milling head) for mounting a milling cutter is arranged at the front end of a ram capable of moving back and forth and can move up and down perpendicular to a transverse sliding table (indexing carriage) for mounting a needle bed to form a ram Y parallel to the X cross of the indexing carriage, and a milling head Z is vertical to the longitudinal direction of the indexing carriage, so that the size and the weight of the ram are lengthened and widened for solving the load and vibration generated by multi-cutter cutting, and the single weight of the equipment is used for processing the width of a needle plate from 10 tons to 30 tons.
With the improvement of the quality and performance of the computerized flat knitting machine and the increasing market demand, the traditional machine tool structure and the laminated multi-cutter processing method cannot meet the precision requirement of the insert groove of the combined needle bed.
