Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel wire annealing equipment, and in particular to a stainless steel wire annealing equipment. Background Technology

[0002] With the continuous advancement of industrial production and manufacturing processes, the demand for stainless steel wire is gradually increasing. During the processing of stainless steel wire, drawing forces a reduction in cross-section and an increase in length. Simultaneously, the processing stress increases the material's hardness. While cold drawing can achieve the required dimensions and strength, it also reduces the material's plasticity and ductility, increasing internal stress. To eliminate the internal stress generated during cold drawing and restore the material's machinability, annealing is typically required. Annealing is a heat treatment process that involves heating the stainless steel wire to a certain temperature and then slowly cooling it. Annealing allows the grains in the steel to recrystallize, relieving internal stress and thus reducing the material's hardness while improving its plasticity and toughness. Through annealing, the steel's machinability is restored, providing better conditions for subsequent processing.

[0003] In the prior art, Chinese utility model patent with publication number CN221440818U discloses a multi-head annealing device for copper wire, comprising a main body, cleaning tubes, a support plate, and a base. A first motor is mounted above the front end of the base, with a first rotating shaft at one end and a take-up reel on the first rotating shaft. A second motor is mounted above the rear end of the base, with a second rotating shaft at one end and a pay-off reel on the second rotating shaft. A housing is mounted on the upper part of the base, with connecting seats at both the front and rear ends of the housing. Several cleaning tubes are movably connected between the connecting seats. The inner surface of the cleaning tube is equipped with a scrubbing layer to clean dust and dirt from the copper wire surface. An auxiliary gear is fixedly connected to the cleaning tube. A third motor is installed inside the outer casing, with a third rotating shaft at one end. A main gear is fixedly connected to the third rotating shaft, and the main gear and auxiliary gear are meshed. The main body of the equipment is located at the rear of the outer casing. An annealing furnace is located inside the front end of the main body. There are partition chambers on both the front and rear sides of the annealing furnace. A cooling chamber is located inside the rear end of the main body. An air pipe is located below the annealing furnace, with an electrically controlled valve on the air pipe and an air supply source at one end of the air pipe.

[0004] The aforementioned technology guides the wire through a cleaning tube via a pay-off and take-up reel for cleaning, before sending it to an annealing furnace for annealing. However, this technology has several problems: First, since the wire is purchased, and the cleaning tube is a single unit, maintenance personnel find it difficult to clean when the cleaning layer is damaged. Furthermore, the relatively fixed relationship between the cleaning layer and the wire makes it easy for waste material to accumulate in certain areas within the cleaning layer. When residue accumulates in these areas, the cleaning effect is reduced when subsequent sections of wire enter. Summary of the Invention

[0005] The main purpose of this invention is to provide a stainless steel wire annealing device, which aims to reduce the maintenance difficulty and cost for maintenance personnel, improve the cleaning effect of the cleaning layer on the wire surface, prevent waste from accumulating inside the cleaning layer, and ensure the efficiency and stability of the entire cleaning process.

[0006] To achieve the above objectives, this utility model proposes a stainless steel wire annealing apparatus, comprising:

[0007] Clean the housing, which is located between the heating furnace and the wire feeding reel;

[0008] A first cleaning roller and a second cleaning roller are both disposed inside the cleaning housing and are interlocked with each other.

[0009] Two cleaning layers, each of which is detachably and fixedly connected to the first and second cleaning rollers respectively;

[0010] A receiving plate is fixedly connected to the top wall of the cleaning housing, and the lower side of the receiving plate is hinged to the first cleaning roller.

[0011] An opening and closing cylinder is fixedly connected in the cleaning housing. The telescopic shaft of the opening and closing cylinder is fixedly connected to a lifting plate. Two limiting posts are fixedly connected to the lifting plate, and each of the limiting posts slides and abuts against the inner wall of the cleaning housing.

[0012] A positioning assembly is used to limit the movement of the first cleaning roller and the second cleaning roller, and the positioning assembly is disposed between the receiving plate and the lifting plate.

[0013] In one possible implementation, the locking component includes:

[0014] The first gear ring and the second gear ring are fixedly connected to the outer side surfaces of the first cleaning roller and the second cleaning roller, respectively.

[0015] A drive rack slides and abuts against the lower side of the receiving plate, and the drive rack meshes with the first gear ring.

[0016] A positioning cylinder is fixedly connected to the upper side of the receiving plate, and the telescopic shaft of the positioning cylinder is fixedly connected to one end of the drive rack.

[0017] A limiting rack slides and abuts against the side of the lifting plate, and the limiting rack meshes with the second gear ring.

[0018] In one possible implementation, the outer rings of the first and second cleaning rollers are both fixedly connected to limiting rings, and each limiting ring has a limiting groove. Two limiting blocks are fixedly connected to the opposite sides of the receiving plate and the lifting plate, and each limiting block abuts against the inner wall of the adjacent limiting groove.

[0019] In one possible implementation, a plurality of fitting posts are fixedly connected to the first cleaning roller, and a plurality of fitting grooves are formed on the second cleaning roller, wherein the fitting posts abut against the inner walls of the fitting grooves.

[0020] In one possible implementation, each of the cleaning layers has a spirally arranged annular groove.

[0021] In one possible implementation, a first pipe and a second pipe are fixedly connected inside the cleaning housing, and the first pipe and the second pipe are respectively disposed on both sides of the first cleaning roller.

[0022] In one possible implementation, a partition is fixedly connected inside the cleaning housing, a spray head is fixedly connected inside the cleaning housing, and a sealing ring is fixedly connected to the partition, the inner diameter of the sealing ring being larger than the outer diameter of the wire.

[0023] In one possible implementation, a guide nozzle is fixedly connected to the outside of the cleaning housing, and a locking nut is threaded onto the guide nozzle.

[0024] This invention's technical solution involves disassembling the cleaning device into a first cleaning roller and a second cleaning roller that can be interlocked. The lifting of the second cleaning roller is controlled, facilitating maintenance personnel to easily maintain and replace the cleaning layer within the first and second cleaning rollers. This reduces maintenance difficulty and costs. Furthermore, in conjunction with a locking component, the interlocked first and second cleaning rollers are directly controlled to perform orderly reciprocating flipping operations, thereby improving the cleaning effect of the cleaning layer on the wire surface. This ensures that locally accumulated dust on the wire surface can be better removed, contributing to improved results in subsequent wire annealing. Simultaneously, the flipping action allows the cleaning layer to continuously clean and maintain its cleaning effect, preventing waste from accumulating inside the cleaning layer and ensuring the efficiency and stability of the entire cleaning process.

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] This utility model proposes an annealing device for stainless steel wire.

[0035] Reference Figures 1 to 4 , Figure 1 This is an enlarged schematic diagram of the structure of a stainless steel wire annealing device according to the present invention; Figure 2 This is a partially enlarged cross-sectional view of an annealing device for stainless steel wire according to the present invention. Figure 3 This is a partially enlarged schematic diagram of an annealing device for stainless steel wire according to this utility model. Figure 1 ; Figure 4 This is a partially enlarged schematic diagram of an annealing device for stainless steel wire according to this utility model. Figure 2 .

[0036] In this embodiment of the invention, a stainless steel wire annealing device includes a cleaning housing 11, a first cleaning roller 12, a second cleaning roller 13, two cleaning layers 14, a receiving plate 16, an opening and closing cylinder 17, and a locking assembly. The cleaning housing 11 is disposed between a heating furnace and a wire feeding reel. The first cleaning roller 12 and the second cleaning roller 13 are both disposed within the cleaning housing 11 and are interlocked with each other. Each cleaning layer 14 is detachably and fixedly connected to the first cleaning roller 12 and the second cleaning roller 13. Inside 13, the cleaning layer 14 can be deformed by itself. For example, if the cleaning layer 14 is a soft material, it can be squeezed into the first cleaning roller 12 and the second cleaning roller 13. The receiving plate 16 is fixedly connected to the top wall of the cleaning housing 11. The lower side of the receiving plate 16 is hinged to the first cleaning roller 12. The opening and closing cylinder 17 is fixedly connected in the cleaning housing 11. The telescopic shaft of the opening and closing cylinder 17 is fixedly connected to the lifting plate 18. The lifting plate 18 is fixedly connected to two limiting posts 19. Each limiting post 19 slides and abuts against the inner wall of the cleaning housing 11.

[0037] The connection and separation of the first cleaning roller 12 and the second cleaning roller 13 are controlled by the opening and closing cylinder 17, which makes it convenient for maintenance personnel to maintain and replace the cleaning layer 14 in the first cleaning roller 12 and the second cleaning roller 13, reducing the maintenance difficulty and maintenance cost.

[0038] A positioning assembly is used to limit the movement of the first cleaning roller 12 and the second cleaning roller 13. The positioning assembly is disposed between the receiving plate 16 and the lifting plate 18.

[0039] The positioning component directly controls the first cleaning roller 12 and the second cleaning roller 13 to perform orderly reciprocating flipping operations after being fitted by the positioning cylinder 23, thereby improving the cleaning effect of the cleaning layer 14 on the wire surface, ensuring that the dust locally accumulated on the wire surface can be better cleaned, which helps to improve the effect of subsequent wire annealing. At the same time, the flipping action enables the cleaning layer 14 to continuously clean and maintain the cleaning effect, preventing waste from accumulating inside the cleaning layer, and ensuring the efficiency and stability of the entire cleaning process.

[0040] like Figures 2-4 As shown, the positioning assembly includes a first gear ring 21, a second gear ring 211, a drive rack 22, a positioning cylinder 23, and a limiting rack 24. The first gear ring 21 and the second gear ring 211 are fixedly connected to the outer sides of the first cleaning roller 12 and the second cleaning roller 13, respectively. The drive rack 22 slides against the lower side of the receiving plate 16 and meshes with the first gear ring 21. The positioning cylinder 23 is fixedly connected to the upper side of the receiving plate 16. The telescopic shaft of the positioning cylinder 23 is fixedly connected to one end of the drive rack 22. The limiting rack 24 slides against the upper side of the lifting plate 18 and meshes with the second gear ring 211.

[0041] A damper is provided between the limiting rack 24 and the lifting plate 18 to enhance the limiting effect of the limiting rack 24 on the second cleaning roller 13. The second cleaning roller 13 will not shift arbitrarily after separating from the first cleaning roller 12, which makes it convenient for maintenance personnel to quickly and stably engage the first cleaning roller 12 and the second cleaning roller 13 after maintenance. Since the setting of the damper is a technical means familiar to those skilled in the art, it will not be described in detail.

[0042] The positioning assembly directly controls the first cleaning roller 12 and the second cleaning roller 13 to perform orderly reciprocating flipping operations after being fitted together via the positioning cylinder 23, thereby improving the cleaning effect of the cleaning layer 14 on the wire surface. This ensures that locally accumulated dust on the wire surface can be better cleaned, which helps to improve the effect of subsequent wire annealing processing. At the same time, the flipping action allows the cleaning layer 14 to continuously clean and maintain its cleaning effect, preventing waste from accumulating inside the cleaning layer and ensuring the efficiency and stability of the entire cleaning process.

[0043] like Figures 2-4 As shown, each limiting ring 31 is fixedly connected to the outer ring of the first cleaning roller 12 and the second cleaning roller 13 respectively. The limiting groove 32 is opened on the limiting ring 31. The opposite side of the receiving plate 16 and the lifting plate 18 is fixedly connected to the two limiting blocks 33. Each limiting block 33 abuts against the inner wall of the adjacent limiting groove 32.

[0044] The contact relationship between the limiting block 33 and the inner wall of the adjacent limiting groove 32 effectively limits the first cleaning roller 12 and the second cleaning roller 13, ensuring greater stability when the two cleaning rollers reciprocate left and right in the axial direction. This ensures greater stability of the wire during the cleaning process between the first cleaning roller 12 and the second cleaning roller 13, thereby improving the cleaning effect and ensuring the efficiency and accuracy of the cleaning process.

[0045] like Figures 3-4 As shown, several fitting posts 121 are fixedly connected to the first cleaning roller 12, and several fitting grooves 131 are opened on the second cleaning roller 13. The fitting posts 121 and the inner walls of the fitting grooves 131 abut against each other.

[0046] Through the corresponding abutment of the fitting post 121 with the inner wall of the fitting groove 131, the first cleaning roller 12 and the second cleaning roller 13 can achieve rapid separation and fitting connection. This makes it easier for maintenance personnel to maintain and replace the cleaning layer 14 inside the first cleaning roller 12 and the second cleaning roller 13, thereby reducing the difficulty of maintenance for workers and reducing maintenance costs.

[0047] like Figures 3-4 As shown, the spiral groove 15 is formed on the cleaning layer 14;

[0048] When the positioning assembly performs the left and right flipping action of the first cleaning roller 12 and the second cleaning roller 13, the annular groove 15 can increase the ability of each cleaning layer 14 to better wipe the same area of ​​the wire, improve the wiping effect on the wire surface, and at the same time, some of the dust wiped off is more likely to fall into the annular groove 15, so that when the cleaning layer 14 is maintained later, it is convenient for maintenance personnel to remove the accumulated waste and maintain and replace the cleaning layer 14.

[0049] like Figure 1 and Figure 2 As shown, the first pipe 41 and the second pipe 42 are both fixedly connected to the cleaning housing 11, and the first pipe 41 and the second pipe 42 are respectively arranged on both sides of the first cleaning roller 12;

[0050] The first conduit 41 uses airflow to initially clean the surface of the wire entering the cleaning housing 11. This effectively removes easily detached and lighter dust, thus reducing the working pressure on the cleaning layer 14. The second conduit 42 then adsorbs and cleans the surface of the wire after wiping by the cleaning layer 14, quickly removing any remaining impurities and dust from the cleaning process. This further improves the cleaning effect, making the wire surface cleaner and thus improving the effect of the subsequent annealing process.

[0051] like Figure 1 and Figure 2 As shown, the partition 51 is fixedly connected inside the cleaning housing 11, the spray head 52 is fixedly connected inside the cleaning housing 11, and the sealing ring 53 is fixedly connected to the partition 51. The inner diameter of the sealing ring 53 is larger than the outer diameter of the wire.

[0052] By setting up the spray head 52 and coordinating with the ventilation effect of the first duct 41, some of the dust on the surface of the wire is removed through the condensation of atomized water vapor. The condensed water mist carries away this dust, thus cleaning the wire surface more effectively. At the same time, the water mist also keeps the wire surface moist, allowing it to be cleaned more thoroughly when passing through the cleaning layer 14, thereby improving the effect of the subsequent annealing process. In addition, the design of the sealing ring 53 effectively prevents the water mist from spreading through the partition 51, avoiding any impact on other components.

[0053] like Figure 1 and Figure 2 As shown, the guide nozzle 61 is fixedly connected to the outside of the cleaning housing 11, and the guide nozzle 61 is threadedly connected to the clamping nut 62;

[0054] The tightness of the guide nozzle 61 is adjusted by tightening the nut 62, thereby guiding the wire through the guide nozzle 61. During the movement of the wire, due to its own gravity, it mainly causes wear on the lower side of the cleaning housing 11. By setting the guide nozzle 61, it is ensured that the wire is as parallel as possible to the axes of the first cleaning roller 12 and the second cleaning roller 13, thereby reducing wear on the surface of the internal components of the device during the movement of the wire and extending the service life of the internal components. At the same time, combined with the positioning assembly, the surface of the wire can be cleaned better, improving the cleaning effect and thus enhancing the effect of the subsequent annealing process of the wire.
