However, the method can cause the problem that the cost is increased. Comprising a sheet-shaped rod body, heald eyes are formed in the thickness direction of the rod body, a reinforcing part consistent with the length direction of the rod body is arranged on the rod body, and the hardness of the reinforcing part is larger than that of the rod body. In the process of producing the heddle bar, the reinforcing part is added to improve the structural strength of deformation resistance of the whole bar body, so that when the heddle bar moves up and down along with a jacquard machine, the heddle bar cannot be abraded due to the fact that a heddle penetrates through a heddle eye, and the heddle eye cannot be damaged. And the whole rod body is bent and deformed under the action of the acting force, so that the service life of the heddle rod is ensured.

Description

Technical Field

[0001] The utility model relates to the technical field of jacquard machine mechanical accessories, in particular to a long-life harness assembly heald rod. Background Art

[0002] In current textile equipment, healds are an indispensable component, and each heald is responsible for guiding and controlling a warp yarn. During the weaving process, the healds form a shed through lifting and lowering, allowing the weft yarn to pass smoothly. Since the movement of the healds will cause friction in the heald eye, the healds made of traditional iron wires are very likely to deform due to stress. Even for plate-shaped healds, it is difficult to ensure that they remain stable in shape for a long time unless the hardness of the whole material is high. However, this practice will lead to increased costs. When this cost is reflected in the manufacturing and maintenance of the entire jacquard machine, it will cause a significant economic burden.

[0003] Therefore, a long-life harness heald rod is proposed to solve or alleviate the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a long-life harness heald rod.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A long-life harness heald rod comprises a rod body, which is in sheet form and has heald eyes in its thickness direction. A reinforcing part is provided on the rod body in the same length direction, and the hardness of the reinforcing part is greater than that of the rod body.

[0007] Preferably, the reinforcing part is a reinforcing rod, and both sides of the rod body are provided with embedding grooves connected to the heddle eye, and the reinforcing rod is embedded in the embedding groove and has an interference fit therewith.

[0008] Preferably, the heddle eyelet is in the shape of an elongated strip, and both ends thereof are in the shape of a semicircle.

[0009] Preferably, both sides of the rod body are recessed to form guide spherical surfaces connected to the heddle eye, and there are a plurality of guide spherical surfaces on each side of the rod body, and adjacent guide spherical surfaces are arranged tangentially.

[0010] Preferably, a rounded corner is provided at the junction between the guide spherical surface and the heddle eye.

[0011] Preferably, the reinforcing rod is made of tungsten alloy.

[0012] Preferably, it also includes heald loops, which are integrally formed at both ends of the rod body, and both are made of stainless steel.

[0013] The utility model has the following beneficial effects:

[0014] The design of the utility model is a key step of adding a reinforcement part during the production process, the purpose of which is to significantly improve the deformation resistance of the entire heald rod. This reinforcement part ensures that the structural stability of the rod body is significantly enhanced. Therefore, when the heald rod moves up and down at high speed following the modern jacquard machine, although friction will inevitably occur at the perforations of the heald rod, the addition of these reinforcement parts effectively prevents bending deformation caused by friction, thereby maintaining its original shape under the action of mechanics. Through this innovative design, the stability and durability of the heald rod are significantly improved, thereby ensuring its longer service life and better process effect.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] A long-life harness heald rod, such as Figure 1 As shown, it comprises a rod body 1 and a heald eye 2. The heald eye 2 is integrally formed at both ends of the rod body 1, and both are made of stainless steel.

[0021] Among them, Figure 2 As shown, the rod body 1 is in the form of a sheet, and a heddle eye 5 is provided in the thickness direction thereof. The heddle eye 5 is in the form of an elongated strip, and both ends thereof are semicircular. Both sides of the rod body 1 are recessed to form a guide spherical surface 7 connected to the heddle eye 5. There are a plurality of guide spherical surfaces 7 on each side of the rod body 1, and adjacent guide spherical surfaces 7 are arranged tangent to each other. A fillet 6 is provided at the junction of the guide spherical surface 7 and the heddle eye 5.

[0022] like Figure 2 and 3As shown, there is a reinforcing portion on the rod body 1 which is consistent with its length direction, and the hardness of the reinforcing portion is greater than the hardness of the rod body 1. The reinforcing portion is a reinforcing rod 4. Both sides of the rod body 1 are provided with embedding grooves 3 connected to the heddle eye 5. The reinforcing rod 4 is embedded in the embedding grooves 3 and has an interference fit therewith. The reinforcing rod 4 is made of tungsten alloy.

[0023] When people need to produce the heald rod, they only need to place a metal sheet made of stainless steel on the workstation of a punching machine, and use the punch head of the punching machine to complete the punching of the metal sheet, so that people can obtain an integrally formed rod body 1 and heald eye 2, and under the punching, a hole will be formed on the heald eye 2, and a heald eye 5 and a groove 3 connected thereto will be formed on the rod body 1, and then a guide spherical surface 7 is punched on the rod body 1 by the punching machine, and then a rounded corner 6 is derived from the junction of the guide spherical surface 7 and the heald eye 5 by a turning external round chamfering machine.

[0024] Then people put the tungsten alloy reinforcing rod 4 into the embedding groove 3, and use a punching machine to punch both sides of the rod body 1, so that the punching head of the punching machine can press down the reinforcing rods 4 on both sides to deform them, and then fill them into the embedding groove 3, so that the reinforcing rod 4 and the embedding groove 3 have an interference fit, and at the same time send it into the punching machine for punching, and cut off the excess reinforcing rod 4 in the heddle eye 5.

[0025] In the modern weaving industry, there are extremely high requirements for the accuracy and durability of equipment, especially those involving the design of key components of the textile process. For this reason, the present heald rod has been developed. This heald rod has excellent structural strength. This is because the addition of the internal reinforcement rod 4 provides additional load-bearing capacity and stability, which can effectively ensure that the heald rod can withstand the forces of frequent movement without deformation.

[0026] In addition, the design of the heald rod also cleverly incorporates a guide spherical surface 7 and an optimized rounded corner 6 design. This innovation allows the heald to be smoothly and accurately guided when passing through the small and precise heald eye 5. Compared with the traditional angular or sharp edge design, this smooth surface reduces the friction between the heald and the contact point, greatly reducing the risk of wear during the reciprocating motion of the heald. This means that the heald moves more smoothly on the jacquard machine, and the friction loss of the heald eye 5 is effectively controlled, which extends the service life of the equipment and ensures the stability and efficiency of fabric production.

[0027] In summary, the heald rod combining the reinforcing rod 4 and the guide design, through its superb structural strength and precise guiding mechanism, not only improves the efficiency and quality of weaving, but also greatly reduces the loss caused by friction, ensuring the stable operation of the textile equipment and the long-term durability of the heald rod itself. The promotion of this design will bring sustainable benefits to the textile industry.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
