Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stockinette needle used in a circular knitting machine, which has a structure in which each part of the stockinette needle can be manufactured separately into function units and assembled as necessary, and a method for manufacturing the same. be.

Traditionally, the stockinette needles used in circular knitting machines include the 1°O stitching needle, which is made from a wire material with a circular cross section that is bent and then pressed flat, as shown in Figure 1. As shown in the figure, there is a plate needle 200 made from a material obtained by punching a steel strip that has been previously rolled into a flat shape. In the case of the binding needle 100, there is no loss of material, the weight of the needle body is small, and it has appropriate elasticity. The bending requires processing, and since the bending inner diameter 111 is extremely small, there is a drawback that stress from the impact transmitted from the cam concentrates when the stapler 1oo is used, causing damage to the bundt portion 110. Furthermore, in the case of the board 200 shown in FIG. 2, the bundt part 210 has the advantage of having sufficient strength;
Since the punched material is a steel strip that has been flattened in advance, plate scraps will be generated and the material will have a large amount of scrap.The needle itself has a large weight, so if it is reciprocated at high speed during use, the impact will cause the needle to move. Vera 2o3 is damaged or bat 21
There was a drawback that the sliding portion 220 of the 0 was worn out. In addition, since the tip, trunk, bundt, and end of both the binding needle 100 and plate needle 200 are made of the same material and heat-treated at the same time,
For example, it has been necessary to impart different properties to the tip, elasticity to the trunk, and abrasion resistance to the butt.

Historically, one of the problems in manufacturing stockinette needles was that the longitudinal dimension A of stockinette needles was significantly larger than the width dimension B.
Because it has an elongated shape as a whole, it bends during the heat treatment process,
Due to twisting and dimensional distortion, the dimensions of A, C, and D varied between products, which was a significant factor in the occurrence of defective products. In the case of the plate needle 200, the plate needle 200 can also be used to remove the fractured surface during press punching that remains on the sliding part 220 that contacts the cam surface of the circular knitting machine, and to precisely polish the surface to a smooth surface. It has a drawback that it is difficult to work because it has an extremely elongated shape, and the dimensional accuracy of the main dimensions C and D is difficult to match.

Therefore, the purpose of the present invention is to eliminate the drawbacks of the above-mentioned binding needles and plate needles,
By incorporating only the advantages of both, we provide stockinette needles that can be operated at high speed and have a small weight.We also aim to provide stockinette needles that can be operated at high speed and have a low weight. An object of the present invention is to provide a method for manufacturing stockinette needles.

The stockinette needle according to the first invention (first invention) of the present application has a hook at one end and a collar rotatably supported uniaxially in a collar groove, and a tip end of the stockinette needle having a joint at the other end. This is a knitted knitted needle having a shape that is connected at each joint f3 (5), and a needle 13 having a joint part at one end.

a bellow 1:3 rotatably supported in the l2;
The other end has a joint portion 14 having a thickness approximately 1/2 of the thickness of 1° of the tip of the stockinette needle.

The tip portion 10 may be formed from a material obtained by punching rolled steel, but in order to reduce material loss, it is preferable to continuously form the material from a material in which a wire rod is pressed into a flat shape. Is bunt part 3 o one end? Part Nod: 30 Joint part with a thickness approximately 1/2 of the thickness of the main body; has an eye. The bunt portion 3o is punched out from a rolled copper strip, subjected to quenching heat treatment, and then finished with a bunt end surface 3; Since each of the joint parts 14 and :3] are joined by overlapping each other in the thickness direction of the stockinette needle body, the thickness of the joint part after assembly or the thickness of the tip part 10 and the butt part 3U may exceed. The stockinette needle according to the second invention (second invention) of the present application preferably has a thickness of about 1/2 of the thickness of the tip part or the bundt part to prevent At the tip of a stockinette needle having a collar rotatably supported in the collar and having a joint at the other end, one or more joints having a joint at one or both ends, and one or more joints at one or both ends. This stockinette needle is characterized in that one or more butt parts each having a joint are arranged, combined and connected through each joint.

It has 2. '(+7i The joint part 2o may be formed by punching from below the hardened steel, or may be formed by pressing the wire into a flat shape and heat-treating it. In order to make it difficult to transmit the information to the tip part 1o, bending may be performed as necessary. It is the same as the first invention except that it has 31. The connecting portion 20 having only a merging portion can be considered as the connecting portion 20 because the material, material, thickness, etc. of the terminal end portion are the same as the connecting portion 20.

Therefore, in the claims of the present application, when the term "connection section" is used, the term "terminal section" is also included. , as shown in FIG. Connecting part 20, butt part: 3
0 and the terminal end portion 4o are joined by overlapping each other in the thickness direction of the stockinette needle body, so the thickness of the joined portion after assembly may exceed the thickness of the tip portion 10 or the butt portion 30. It is preferable to configure the thickness to be approximately 1/2 of the thickness of the tip portion or the thickness of the butt portion I so that the thickness of the butt portion I is not large.

．． It is characterized in that the respective joint parts of the connection +1s 20 and the bundt part 30 are arranged and combined and joined. This is the same as the second invention in that the terminal end portion 40 can be regarded as the connecting portion 20 having a joint portion at only one end.

Embodiment I of the third invention will be described below based on the attached FIG. 14.
Explain ll. Tip 10. Connecting part 20, top part: 301 connecting part 2 (), butt part: 30 and terminal part 40
are overlapped and joined at each joint to form an integrated stockinette needle. The joining method may be welding, adhesive joining, or any other method, but from the viewpoints of workability during joining, joint strength, and prevention of deformation, it is effective to use the traditional method of joining. Spot welding is also possible, but to overcome the thermal deformation and roughness of the outer surface due to welding, laser beams can focus the energy source on a small point and weld metals together with the inward direction of the gold. Welding is best. Maser beam welding instead of laser beam welding? -1f
Child arm welding has the same effect.
Connecting portion 20, butt portion 3 () and end portion 40, 11
．． Each structure is similar to the second invention.

The stockinette jumper according to the first and second inventions of the present application has the following effects. In other words, it is possible to easily reduce the weight without sacrificing the strength of the knitting part, and since it is possible to use materials and combinations of materials suitable for each part, the durability of the stockinette needle during high-speed use is greatly improved. ? 1. The method for manufacturing stockinette needles according to the 3rd invention of the present application has the following effects. In other words, the construction of the knitting needle is functionally divided into parts, and the tip part, connecting part, knot part, and end part are each made into a standard system. Therefore, it is possible to reduce the number of conventional punching dies and bending dies by 61.In addition, each part that has been heat treated can be erected with an ax, making it possible to reduce the heat treatment process. The irregularities in the dimensions of the sewing machine were absorbed during the assembly process, and the dimensional accuracy of stockinette needle processing was greatly improved, and the quality was lower than that.

In addition, the tip part, which requires the most complicated process in stockinette needle processing, is processed from the wire rod (this eliminates material loss and cuts the processed part [without stripping the wire material, making it possible to carry out each process sequentially). Threading (this made it possible to perform continuous automation by connecting only the tips of stockinette needles in multiple steps, which was previously impossible.Also, it was extremely difficult in the past)
Since the curve 1't'j dense 1i1F polishing of the bunt end ml can be done with only the bunt part, it is easier to work and the machining accuracy has also been improved. In addition, the connecting part is made by punching a hardened steel strip or by pressing a wire rod with only 11 steps of pressure, so processing efficiency is good.

Furthermore, in the example, by integrating each part by welding with a racer beam, maser beam, or electron beam (G), we can heat-melt and bond two high-technical cores with Li2 in a very short time locally. 1. Sufficient strength is obtained without deformation or distortion caused by normal welding.
