Yarn guide plate for patternbars of warp knitting machine

Abstract

The invention discloses a yarn guide plate for the patternbars of a warp knitting machine and a magnesium alloy section forming process thereof. The yarn guide plate of the patterbars of the warp knitting machine comprises a yarn guide plate base body and rails arranged on the yarn guide plate body; the yarn guide plate base body and the rails are in an integrated structure; the non-bearing part of the yarn guide plate base body is provided with a hollow cavity; the surface of the yarn guide plate is provided with a nickel layer or a Teflon layer. The weight is lowered due to the adopted light magnesium alloy section. The yarn guide plate is formed integrally, and secondary machining of the trails is not needed, so that the buckling or deformation of the yarn guide plate caused by the secondary machining is avoided, and the stability is better. The yarn guide plate is subjected to surface treatment through Teflon spraying or chemical nickel-plating, so that the surface hardness of the yarn guide plate, especially the surface hardness of the inner sides of the rails is further enhanced, and the service life of the yarn guide plate is prolonged. According to the invention, the novel magnesium alloy section of the yarn guide plate for the patternbars of the warp knitting machine, which is stable in dimension and high in precision, is obtained by adjusting and combining a forming process and strictly controlling the contents of some alloying elements on the basis of the commercial AZ80 magnesium alloy.

Description

technical field [0001] The invention relates to the technical field of textile machinery, and more specifically relates to a yarn guide plate for pattern combs of warp knitting machines. Background technique [0002] The textile industry is a traditional industry. With the increasingly stringent constraints on product energy consumption and the increasing reduction in production costs due to economic development, my country's textile industry has entered the stage of transformation and upgrading, and the progress is rapid. High-end automation and intelligent textile equipment is the development trend of the textile industry, and vigorously improving the level of textile machinery equipment is one of the effective means to promote the rapid upgrading of the textile industry. [0003] In order to reduce the weight of equipment, reduce energy consumption and improve production efficiency, aluminum alloys are widely used in textile machinery, which has greatly improved equipment...

Problems solved by technology

Although the density of carbon fiber reinforced plastics is lower than that of magnesium alloys, its cost is high, and it is currently limited to one-time molding and cannot be processed later, which greatly restricts the assembly and use of parts

[0005] At present, the latest warp knitting machines (such as multi-bar jacquard lace machines) are all computer-controlled and equipped with wire flower comb type electronic traverse technology, which can develop more perfect and exquisite high-grade lace. The patterned comb guide plate on the knitting machine is made of aluminum alloy extruded profile, and its heavy weight is not conducive to the high-speed operation of the patterned comb and the patterned guide needle

After the yarn guide plate is extruded, the track is set on the yarn guide plate by machining. Since the tracks are required to be equidistantly distributed on the yarn guide plate, the secondary processing accuracy is high, and the secondary processing wastes raw materials. , and additional processing costs are added, and secondary processing can cause deformation of the yarn guide plate, affecting the straightness of its length direction
