Description

Technical Field

[0001] This utility model relates to the field of stainless steel wire processing technology, specifically to a heating device for stainless steel wire. Background Technology

[0002] After being cold-rolled under pressure, wire undergoes rapid hardening with an extremely high hardening rate, resulting in a significant increase in wire strength and making it difficult to process and shape. Therefore, it requires multiple processing steps, which increases costs.

[0003] When processing stainless steel wire, which is either non-magnetic or only slightly magnetic, traditional electromagnetic induction technology is mainly used to heat metal materials with strong magnetism. Furthermore, the radiant heating mode of muffle furnaces results in very long production lines and extremely low heating efficiency. At the same time, it also leads to uneven heating for wire that is being continuously transported and processed. Utility Model Content

[0004] The purpose of this invention is to provide a heating device for stainless steel wire to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heating device for stainless steel wire, comprising a support frame and a housing mounted on the support frame, wherein a wire body is installed inside the housing, and a conductive roller assembly is also provided inside the housing, the conductive roller assembly comprising a first conductive roller and a second conductive roller rotatably connected to the housing, a transmission space being formed between the first conductive roller and the second conductive roller for transmitting the wire body; a heating mechanism for heating the wire body is provided on the housing.

[0006] Furthermore, the heating mechanism includes copper sleeves mounted on the first conductive roller and the second conductive roller, and each copper sleeve is equipped with a carbon brush conductive component.

[0007] Furthermore, the heating mechanism also includes a first gathering plate and a second gathering plate that are vertically slidably connected inside the housing. Both the first gathering plate and the second gathering plate are provided with heating parts, and the two heating parts form a heating space. The wire body is installed inside the housing. The housing is provided with a driving mechanism for driving the first gathering plate and the second gathering plate away from each other, so that the wire body can pass smoothly through the heating space.

[0008] Furthermore, the driving mechanism includes a linkage unit disposed between the first gathering plate and the second gathering plate. The linkage unit includes a linkage gear rotatably connected to the housing. A first rack is fixedly connected to the first gathering plate, and a second rack is fixedly connected to the second gathering plate. The first rack and the second rack are respectively meshed on both sides of the linkage gear. An adjusting block is fixedly connected to the first gathering plate, and a driving part is disposed between the housing and the adjusting block.

[0009] Furthermore, the driving unit includes a driving block slidably connected to the housing, a driving rod fixedly connected to the driving block, and a connecting spring provided between the driving rod and the housing. The adjusting block is provided with a driving groove adapted to the driving block, and the driving block slides through the driving groove to drive the adjusting block to slide upward. A locking part is also provided between the housing and the adjusting block.

[0010] Furthermore, the locking part includes a locking rod slidably connected to the housing, a locking block fixedly connected to the locking rod, a locking spring provided between the locking block and the housing, and a locking groove adapted to the locking block on the adjusting block. The elastic force of the locking spring drives the locking block to engage in the locking groove, thereby fixing the adjusting block.

[0011] Furthermore, a positioning element is provided between the first gathering plate and the second gathering plate; the positioning element includes a plurality of limiting blocks fixedly connected to the first gathering plate and the second gathering plate, each of the limiting blocks being slidably connected to the box body through a limiting groove; and a compression spring is provided between each limiting block and the box body, the elastic force of the compression spring driving the first gathering plate and the second gathering plate to move closer to each other.

[0012] Furthermore, a protective plate is fixedly connected to the first gathering plate, and a protective frame is fixedly connected to the second gathering plate, with the protective plate and the protective frame being slidably connected.

[0013] Furthermore, the protective frame is provided with an adapter groove that is compatible with the wire body, and a protrusion is fixedly connected to the protective plate, with the protrusion slidably connected to the adapter groove.

[0014] Furthermore, the heating part includes a heating plate, on which multiple sets of heat-conducting fins are fixedly connected.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the heating equipment for stainless steel wire can heat the wire body during transportation, so it is not necessary to heat the wire body when the wire body is stopped. This improves the working efficiency of the heating equipment and makes the wire body heat more evenly during the heating operation, thus meeting the work requirements.

[0016] Furthermore, heating the wire rod body can reduce its strength to a certain extent, thus facilitating the subsequent rolling process and achieving better results.

[0017] Furthermore, the heating equipment, through the cooperation between the carbon brush conductive component and the copper sleeve, is able to heat austenitic non-magnetic wires, thus further expanding the applicability of the heating equipment.

[0018] Beneficial effects: When heating stainless steel wire, an external power supply connects to the carbon brush conductive component, allowing the component to provide a large current and low voltage. This large current is then sequentially transmitted to the copper sleeve, shaft, and conductive roller assembly. The conductive roller assembly includes two sets of first and second conductive rollers, arranged vertically in pairs within each set. During wire transfer, the first and second conductive rollers apply a certain pressure to the wire and maintain constant contact to establish a good conductive path. Furthermore, the equipment body is equipped with a temperature sensor, specifically based on existing technology. Two sets of rollers are spaced apart on the left and right sides of the wire. An external temperature sensor monitors the temperature of the wire body between the two sets of first and second conductive rollers. The current and voltage of this section are controlled according to the temperature change to form a closed-loop control. This allows for heating of the wire between the two sets of first and second conductive rollers. This not only allows for continuous heating of the wire body but also enables heating of this section of wire in a short time, meeting the heating requirements of stainless steel wire. Furthermore, it offers high heating efficiency, fast speed, good stability, and more uniform heating. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-10This utility model provides a technical solution: a heating device for stainless steel wire, including a support frame 1 and a housing 2 mounted on the support frame 1. The support frame 1 has multiple sets of support legs at its bottom, each with an anti-slip pad to improve the stability of the heating device during operation. The housing 2 houses the wire body 3, and also contains a conductive roller assembly 19. The conductive roller assembly 19 includes a first conductive roller and a second conductive roller rotatably connected to the housing 2. Specifically, there are two sets of the first and second conductive rollers, respectively located on both sides of the device. A transmission space is formed between the first and second conductive rollers for transmitting the wire body 3. The housing 2 is equipped with a heating mechanism for heating the wire body 3.

[0033] In the embodiments provided by this utility model, the heating mechanism includes copper sleeves 20 mounted on the first and second conductive rollers. Specifically, the first and second conductive rollers are connected to a power component via rotating shafts, providing power for their rotation. More specifically, the copper sleeves 20 are mounted on the rotating shafts, and each copper sleeve 20 is equipped with a carbon brush conductive component 21. Specifically, the carbon brush conductive component 21 is electrically connected to an external power source, providing a heat source for heating the copper sleeves 20, thereby transferring heat to the first and second conductive rollers, allowing them to be heated and thus heating the wire body 3. Specifically, this heating device, through the cooperation between the carbon brush conductive component 21 and the copper sleeves 20, can heat austenitic non-magnetic wires, further improving the applicability of the heating device.

[0034] When heating the stainless steel wire, an external power supply is connected to the carbon brush conductive component 21, which provides a large current and low voltage. This large current is then sequentially transmitted to the copper sleeve 20, the rotating shaft, and the conductive roller assembly 19. The conductive roller assembly 19 includes two sets of first conductive rollers and a second conductive roller. The first and second conductive rollers in each set are arranged vertically, two to a group. During the transmission of the stainless steel wire, the first and second conductive rollers apply a certain clamping force to the wire and remain in contact to establish a good conductive path. The equipment body is also equipped with a temperature sensor, specifically based on existing technology. Two sets of first and second conductive rollers are spaced apart on the left and right sides of the wire. An external temperature sensor monitors the temperature of the wire body 3 between the two sets of first and second conductive rollers. The current and voltage of this section are controlled according to the temperature change to form a closed-loop control. This can heat the wire between the two sets of first and second conductive rollers. This not only allows for continuous heating of the wire body 3, but also allows for heating of this section of wire in a short time, meeting the heating requirements of stainless steel wire. Furthermore, it offers high heating efficiency, fast speed, good stability, and more uniform heating.

[0035] This utility model also provides another embodiment, in which the heating mechanism further includes a first gathering plate 4 and a second gathering plate 5 vertically slidably connected inside the housing 2. Both the first gathering plate 4 and the second gathering plate 5 are provided with heating elements, forming a heating space. A wire body 3 is installed inside the housing 2; and the housing 2 is provided with a driving mechanism for driving the first gathering plate 4 and the second gathering plate 5 away from each other, so that the wire body 3 can smoothly pass through the heating space.

[0036] Specifically, the heating mechanism in this embodiment includes a first gathering plate 4 and a second gathering plate 5 vertically slidably connected inside the housing 2. Both the first gathering plate 4 and the second gathering plate 5 are equipped with heating elements, forming a heating space. A wire body 3 is installed inside the housing 2, and specifically, the wire body 3 is in operation. Specifically, when the first gathering plate 4 and the second gathering plate 5 approach each other, the heating elements on both sides heat the wire body 3, thus better concentrating heat. When the wire body 3 passes through the heating space, this method provides a better heating effect compared to the prior art where the wire body 3 directly passes through the housing 2, thereby greatly improving the heating efficiency of the heating equipment and consequently increasing the production efficiency of the wire body 3. Furthermore, the housing 2 is equipped with a driving mechanism to move the first gathering plate 4 and the second gathering plate 5 away from each other, allowing the wire body 3 to pass smoothly through the heating space. Therefore, during use, the driving mechanism moves the first gathering plate 4 and the second gathering plate 5 away from each other, leaving sufficient space for the wire body 3 to pass smoothly through the heating space, meeting the heating needs of the wire body 3 and resulting in better performance.

[0037] In another embodiment of this utility model, the driving mechanism includes a linkage unit 6 disposed between the first gathering plate 4 and the second gathering plate 5. The linkage unit 6 includes a linkage gear 6.3 rotatably connected to the housing 2. A first rack 6.1 is fixedly connected to the first gathering plate 4, and a second rack 6.2 is fixedly connected to the second gathering plate 5. The first rack 6.1 and the second rack 6.2 are respectively meshed on both sides of the linkage gear 6.3. An adjusting block 14 is fixedly connected to the first gathering plate 4, and a driving part 15 is disposed between the housing 2 and the adjusting block 14. Therefore, when it is necessary to install the wire body 3, the first gathering plate 4 is slid upward by the driving part 15, and the second gathering plate 5 is driven downward by the cooperation between the first rack 6.1, the second rack 6.2, and the linkage gear 6.3, thus leaving enough space to install the wire body 3 and meeting the working requirements.

[0038] In another embodiment of this utility model, the driving unit 15 includes a driving block 15.1 slidably connected to the housing 2. A driving rod 15.2 is fixedly connected to the driving block 15.1, and a connecting spring 15.3 is provided between the driving rod 15.2 and the housing 2. The adjusting block 14 has a driving groove 15.4 adapted to the driving block 15.1. The driving block 15.1 slides through the driving groove 15.4, driving the adjusting block 14 to slide upward. Specifically, both the driving block 15.1 and the driving groove 15.4 are wedge-shaped. During use, when the driving rod 15.2 drives the driving block 15.1 to slide inside the driving groove 15.4, the adjusting block 14 will drive the first gathering plate 4 to slide upward. A locking part 16 is also provided between the housing 2 and the adjusting block 14. When the first gathering plate 4 slides upward to the predetermined position, the adjusting block 14 is fixed by the locking part 16, thereby fixing the state of the first gathering plate 4 and the second gathering plate 5, resulting in better performance.

[0039] In another embodiment of this utility model, the locking part 16 includes a locking rod 16.3 slidably connected to the housing 2, a locking block 16.1 fixedly connected to the locking rod 16.3, a locking spring 16.4 provided between the locking block 16.1 and the housing 2, and a locking groove 16.2 adapted to the locking block 16.1 is provided on the adjusting block 14. The elastic force of the locking spring 16.4 drives the locking block 16.1 to engage in the locking groove 16.2, thus fixing the adjusting block 14. After the wire body 3 is heated, the locking rod 16.3 is driven to slide away from the locking groove 16.2, so that the locking block 16.1 slides out from the locking groove 16.2.

[0040] In another embodiment of this utility model, a positioning element is provided between the first gathering plate 4 and the second gathering plate 5. The positioning element includes a plurality of limiting blocks 11 fixedly connected to the first gathering plate 4 and the second gathering plate 5. Each limiting block 11 is slidably connected to the housing 2 through a limiting groove, thereby improving the stability of the first gathering plate 4 and the gathering plate when sliding. Furthermore, a compression spring 12 is provided between each limiting block 11 and the housing 2. The elastic force of the compression spring 12 drives the first gathering plate 4 and the second gathering plate 5 to move closer to each other, meeting the working requirements.

[0041] In another embodiment of this utility model, a protective plate 7 is fixedly connected to the first gathering plate 4, and a protective frame 8 is fixedly connected to the second gathering plate 5. The protective plate 7 and the protective frame 8 are slidably connected. Therefore, when the elastic force of the compression spring 12 drives the first gathering plate 4 and the second gathering plate 5 to approach each other, the protective plate 7 is engaged with the door of the protective frame 8, which plays a certain sealing role and prevents impurities from entering the interior of the first gathering plate 4 and the second gathering plate 5.

[0042] In another embodiment of this utility model, the protective frame 8 is provided with an adapter groove 18 that is adapted to the wire body 3, and the protective plate 7 is fixedly connected with a protrusion 17. The protrusion 17 is slidably connected to the adapter groove 18, which further improves the sealing performance of the first gathering plate 4 and the second gathering plate 5.

[0043] In the embodiments provided by this utility model, each limiting block 11 is provided with a limiting telescopic rod 13 between it and the box 2, thereby improving the stability of the first gathering plate 4 and the second gathering plate 5 when they slide.

[0044] In another embodiment of this utility model, the heating part includes a heating plate 9, and multiple sets of heat-conducting fins 10 are fixedly connected to the heating plate 9, so as to heat the wire body 3.

[0045] In another embodiment of this utility model, a through groove is provided on the housing 2, and the wire body 3 is slidably connected to the housing 2 through the through groove. The through groove and the adapter groove 18 are on the same horizontal line, so as to facilitate the wire body 3 to enter the housing 2 for heating operation.

[0046] It should be noted that all electrical equipment involved in this application can be powered by batteries or external power sources.
