[0002] The production process of diamond wire mainly includes pre-treatment, pre-plating, sanding, thickening and post-treatment, which is done by evenly electroplating diamond powder particles on the high-strength busbar with a certain distribution density. In the production process of diamond wire, the main unqualified factors are broken wire, light, diamond sand accumulation and other problems. Among them, broken wire is related to the breaking force and surface quality of the busbar itself, and is also related to the abnormality of the production machine. Human factors may also cause broken wire.

[0003] In the existing multi-wire machine, when one wire breaks during the manufacturing process of diamond wire, high-tensile curling will occur, and there is a high probability that the wire will be entangled with other wire ends, causing the other wire ends to break one after another, thereby causing a large number of wire breaks, seriously affecting the qualification rate of the diamond wire and causing great economic losses.

[0004] In view of this, it is necessary to propose a new technical solution to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0030] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0032] Example

[0033] The present embodiment provides an insertable anti-wire break device 100, which is installed on a diamond wire multi-wire mouth production device to prevent batch wire breakage.

[0034] Analysis of the causes of batch disconnection

[0035] Generally speaking, the normal production process of diamond wire mainly includes pre-treatment process, sanding process and heat treatment process; among them, the pre-treatment process further includes steps such as unwinding, pickling, alkali washing, and water washing, the sanding process further includes steps such as pre-plating, sanding, and thickening, and the heat treatment process further includes steps such as oven, photography, and winding. The entire equipment is provided with transmission rollers 40 at multiple locations, on which diamond wires 90 are wound. The transmission rollers 40 drive the diamond wires 90 forward under the drive of the driving device. In certain links of the production of diamond wires 90, such as pre-plating, sanding, and thickening, each diamond wire 90 needs to be wound around the transmission roller 40 for several turns to ensure that the diamond wire 90 is in a taut and straight state during the entire conveying process. The position occupied by the same diamond wire 90 on the transmission roller 40 is called a wire mouth.

[0036] See also Figure 1 , shows a schematic diagram of the state where four diamond wires 90 are wound around a transmission roller 40 , each diamond wire 90 is wound around the transmission roller 40 four times, so there are a total of sixteen turns of diamond wire and four wire openings on the transmission roller 40 .

[0037] It is precisely because the diamond wire 90 needs to be wound around the driving roller 40 for multiple turns that the distance between the wire ends becomes shorter, which makes it easy for the diamond wires 90 of two adjacent wire ends to get tangled. Once a diamond wire 90 breaks, it will be rolled up with high tension due to elasticity. The rolled diamond wire 90 has a high probability of getting tangled up with other wire ends, causing other wire ends to break one after another, thus causing batch breakage and huge losses.

[0038] It is worth mentioning that the production process of the diamond wire 90 is actually to complete a series of processes including sand plating on the busbar to obtain the finished diamond wire 90. For the sake of simplicity, this article does not distinguish between the busbar and the finished diamond wire 90, but uniformly describes the diamond wire 90.

[0039] Insertion type anti-belt break device

[0040] The diamond wire 90 multi-wire mouth production equipment of this embodiment is improved on the basis of the existing equipment. Specifically, an insertable anti-belt break device 100 is installed at the above-mentioned transmission rollers 40, especially at the transmission rollers 40 in the above-mentioned pre-plating, sanding and thickening links.

[0041] Please refer to Figure 2 and Figure 3 Specifically in this embodiment, the insertable anti-band break device 100 includes a fixed bracket 10, a movable bracket 20 and an isolation needle 30.

[0042] The fixing bracket 10 is used to fix the entire plug-in anti-belt break device 100 on the rack of the production equipment, and specifically includes a fixing plate 11, a connecting rod 12 and a mounting plate 13. The fixing plate 11 and the mounting plate 13 are arranged in parallel, and the connecting rod 12 is connected between the two. During installation, the fixing plate 11 is fixed to the rack of the production equipment (not shown) by welding or bolt connection. The connecting rod 12 extends the mounting plate 13 to the top of the transmission roller 40. It is worth mentioning that the length direction of the mounting plate 13 is consistent with that of the transmission roller 40. Specifically, two rows of positioning holes 14 are provided on the mounting plate 13, and a certain distance is preset between the two rows of positioning holes 14.

[0043] Please refer to Figure 4 The movable bracket 20 is used to cooperate with the fixed bracket 10 so that the movable bracket 20 can switch between two different plane positions relative to the fixed bracket 10. Specifically in this embodiment, the movable bracket 20 includes a frame body 21 and a positioning rod 22. The number of the positioning rods 22 is consistent with the number of each row of positioning holes 14 on the fixed bracket 10. For example, in this embodiment, the number of each row of positioning holes 14 is two, and the movable bracket 20 is provided with two positioning rods 22. The diameter of the positioning rod 22 matches the diameter of the positioning hole 14. Of course, in order to make the movable bracket 20 more stably inserted into the positioning hole 14, the diameter of the positioning rod 22 can be set to be slightly larger than the diameter of the positioning hole 14. This is a conventional setting in the art and will not be described in detail. Specifically, when installing the movable bracket 20, the two positioning rods 22 are selectively inserted into one of the rows of positioning holes 14, so as to achieve the purpose of flexibly switching the movable bracket 20 between different plane positions.

[0044] Please refer to Figure 5 In order to ensure that the movable bracket 20 is firmly connected to the fixed bracket 10, a fixing sleeve 23 may be provided to cooperate with the positioning rod 22. For example, the fixing sleeve 23 is made of rubber, and the elastic sleeve of the rubber is used to clamp the end of the positioning rod 22 away from the frame 21, thereby improving the connection stability of the movable bracket 20. Another example is that the fixing sleeve 23 is made of metal, and the positioning rod 22 is also made of metal. An internal thread is provided on the fixing sleeve 23, and an external thread is provided on the positioning rod 22. The threaded connection between the two can also improve the connection stability between the movable bracket 20 and the mounting plate 13.

[0045] See also Figure 6Specifically, in this embodiment, the isolation needle 30 includes a needle head 31 and a needle rod 32, and the neck of the needle rod 32 near the needle head 31 is provided with an external thread, and the frame 21 of the movable bracket 20 is provided with a plurality of connection holes 24, and the connection holes 24 are provided with internal threads. When installing, one end of the isolation needle 30 passes through the connection holes 24 and is threadedly connected to the frame 21, thereby fixing the isolation needle 30. Specifically, the diameter of the neck of the needle rod 32 is larger than the diameter of the lower end of the needle rod 32, and this setting is conducive to improving the stability of the connection between the isolation needle 30 and the frame 21.

[0046] As a preferred solution, several cracks 15 can be provided on the mounting plate 13, and the number of the cracks 15 is consistent with the number of each row of positioning holes 14. The cracks 15 run through one side of the mounting plate 13, and each crack 15 connects two positioning holes 14 on the same side. For example, in this embodiment, each crack 15 connects the upper and lower positioning holes 14. This arrangement utilizes the elasticity of the mounting plate 13 itself, so that when the movable bracket 20 switches between the upper and lower rows of positioning holes 14, it can pass through the cracks 15 without removing the entire movable bracket 20, which can improve the switching efficiency of the movable bracket 20.

[0047] In this embodiment, the number of isolation needles 30 is one less than the number of thread ports. For example, if the number of thread ports in this embodiment is four, three isolation needles 30 are sufficient. Of course, in order to match the number of thread ports, a plurality of connection holes 24, for example, 5-8, can be provided on the frame 21 of the movable bracket 20, and the number of isolation needles 30 can be flexibly selected according to the number of thread ports. It should be noted that the distance between two adjacent isolation needles 30 is preferably equal to the distance between the two thread ports.

[0048] How it works

[0049] See also Figure 2 and Figure 3 In the working state, the movable bracket 20 is inserted into the lower row of positioning holes 14 (such as Figure 3 As shown in FIG. 1 , the isolation needle 30 is inserted between the plurality of wire openings, thereby isolating the diamond wires 90 of the plurality of wire openings from each other, and at this time, the bottom end of the isolation needle 30 abuts against the surface of the driving roller 40. If a wire break occurs, the rolled diamond wire 90 is blocked by the isolation needle 30 and will not be entangled with the adjacent diamond wire 90, thereby avoiding the phenomenon of batch wire breakage.

[0050] In the rolled-down state, the movable bracket 20 is manually inserted into the upper row of positioning holes 14 (such as Figure 2 As shown), the isolation needle 30 is lifted up to facilitate further production operations.

[0051] Thus, with the aid of the insertable anti-wire break device 100 , the present invention can realize the independent operation of the diamond wires 90 at each wire opening, preventing the broken diamond wires 90 from being entangled with the diamond wires 90 at adjacent wire openings, thereby avoiding or reducing the occurrence of batch wire breaks.

[0052] Other Notes

[0053] During the production process of the diamond wire 90, its working environment is above the nickel-containing solution. Although there is no direct contact, the nickel concentration in the air is relatively high and corrosive. Therefore, the main materials of the insertable anti-band break device 100 are all anti-corrosion materials, among which the main materials of the fixed bracket 10 and the connecting bracket can be stainless steel, PA and other materials, the isolation needle 30 can be made of stainless steel, titanium alloy and other easy-to-form materials, and the fixed sleeve is mainly made of rubber or stainless steel and other materials.

[0054] It should also be noted that the needle rod 32 of the isolation needle 30 in this embodiment is cylindrical. In other embodiments, the needle rod 32 of the isolation needle 30 can also be set to be flat, diamond-shaped or other geometric shapes.

[0055] The isolation needles 30 of this embodiment are fixed to the movable bracket 20 in a detachable connection manner. In some other embodiments, the isolation needles 30 can also be integrally formed on the movable bracket 20, as long as the distance between the isolation needles 30 is equal to the distance between the wire openings.

[0056] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom still fall within the scope of protection of the present invention.
