Abstract
Description
Technical Field
[0001] This utility model relates to the field of precision stainless steel strip production and processing technology, and in particular to an electromechanical strip threading device. Background Technology
[0002] In the production of precision stainless steel strip, bright annealing is a special process that softens the steel strip through high-temperature solution heat treatment at temperatures above 1100℃. The annealing furnace operates continuously for 24 hours. If a strip breakage occurs, the furnace needs to be cooled down and the strip re-threaded. The furnace's lifespan is shortened due to frequent temperature changes and thermal expansion and contraction. Furthermore, it takes ten days to return to normal production conditions after cooling down and then heating up again, which affects production efficiency.
[0003] To solve this problem, the usual practice is to place a high-temperature resistant nickel-chromium wire inside the furnace. After the strip breaks, the nickel-chromium wire is used to thread the strip through, and the precision stainless steel strip is then manually pulled through the annealing furnace to soften it. However, this method has the following drawbacks:
[0004] 1. Manual pulling is time-consuming and labor-intensive, which will affect the production efficiency of precision stainless steel strips.
[0005] 2. Manual pulling will cause wear and tear on the nickel-chromium wire. Once the nickel-chromium wire breaks and becomes unusable, it needs to be replaced. However, nickel-chromium wire is expensive and has high operating costs, which will increase the overall production cost of the equipment. Utility Model Content
[0006] In response to the shortcomings of the existing production technology, the applicant provides an electromechanical threading device. By improving the structure of the electromechanical threading device, the production efficiency of precision stainless steel strips can be increased. At the same time, the wear of nickel-chromium wire can be reduced, thereby increasing the service life of nickel-chromium wire and reducing the overall production cost of the electromechanical threading device.
[0007] The technical solution adopted in this utility model is as follows:
[0008] An electromechanical threading device includes: a first nichrome wire, a drive mechanism, and two guide mechanisms. A precision stainless steel strip is mounted on the first nichrome wire. The first nichrome wire is wound around the drive mechanism, which passes through an annealing furnace. The drive mechanism drives the first nichrome wire to move, so that the first nichrome wire drives the precision stainless steel strip through the annealing furnace and undergoes softening treatment inside the annealing furnace. The two guide mechanisms are located at both ends of the first nichrome wire, and the first nichrome wire abuts against the guide mechanisms. The guide mechanisms are used to guide the first nichrome wire.
[0009] Therefore, by driving the first nickel-chromium wire through the drive mechanism, compared with the existing manual pulling method, this method has a simple structure, is easy to operate, can shorten the threading time, and thus improve the production efficiency of precision stainless steel strip. At the same time, through the design of two guide mechanisms, the first nickel-chromium wire is guided during its movement, thus avoiding friction between the first nickel-chromium wire and the annealing furnace wall, which would cause wear and damage to the first nickel-chromium wire, thereby increasing the service life of the first nickel-chromium wire and reducing the production cost of the entire electromechanical threading device.
[0010] As a further improvement to the above technical solution: the driving mechanism includes a driving member and a winding roller, the driving end of the driving member being connected to one end of the winding roller, and the first nichrome wire being wound on the winding roller. Thus, the rotation of the winding roller is controlled by the driving member to control the movement of the first nichrome wire.
[0011] For example, the driving component uses a motor.
[0012] As a further improvement to the above technical solution: the guiding mechanism includes a first fixed block, a guide roller, and a second fixed block arranged sequentially from top to bottom. The first fixed block and the guide roller are both connected to the annealing furnace, and the two ends of the guide roller are rotatably connected to the first fixed block and the second fixed block, respectively. Thus, the two guide rollers and the winding roller form a stable triangular support structure, ensuring that the first nichrome wire is in a triangular shape and passes through the annealing furnace in a straight line. This avoids friction between the first nichrome wire and the annealing furnace wall, preventing wear and damage to the first nichrome wire.
[0013] As a further improvement to the above technical solution: the transverse cross-section of the second fixing block is L-shaped. Thus, the L-shaped second fixing block provides a space between the second fixing block and the annealing furnace, which facilitates the installation and removal of the first nickel-chromium wire and the precision stainless steel strip.
[0014] It also includes: a second nickel-chromium wire, which passes through a precision stainless steel strip, and both ends of the second nickel-chromium wire are respectively connected to the first nickel-chromium wire.
[0015] As a further improvement to the above technical solution: the precision stainless steel strip has a through hole, through which the second nickel-chromium wire passes. Therefore, during the installation of the precision stainless steel strip, it is only necessary to pass the second nickel-chromium wire through the through hole and fix both ends of the second nickel-chromium wire to the first nickel-chromium wire (for example, by knotting).
[0016] As a further improvement to the above technical solution: The two ends of the annealing furnace are successively provided with velvet and felt from the inside out. Thus, the velvet and felt can seal the inlet and outlet of the annealing furnace, ensuring that heat dissipates from the furnace interior without affecting the entry and exit of the precision stainless steel strip.
[0017] As a further improvement to the above technical solution, it also includes: a support frame and a base, wherein the annealing furnace and the support frame are both mounted on the base, the driving component is connected to the support frame, and the other end of the winding roller is rotatably connected to the support frame.
[0018] The beneficial effects of this utility model are as follows:
[0019] The first nickel-chromium wire is driven by a drive mechanism. Compared with the existing manual pulling method, this method has a simple structure, is easy to operate, and can shorten the threading time, thereby improving the production efficiency of precision stainless steel strip. At the same time, through the design of two guide mechanisms, the first nickel-chromium wire is guided during its movement. This can avoid friction between the first nickel-chromium wire and the annealing furnace wall, which would cause wear and damage to the first nickel-chromium wire, thereby increasing the service life of the first nickel-chromium wire and reducing the production cost of the entire electromechanical threading device.
[0020] This utility model also has the following advantages:
[0021] 1. The present invention forms a stable triangular support structure between the two guide rollers and the winding roller, so that the first nickel-chromium wire is in a triangular state and passes through the annealing furnace in a straight state. In this way, friction between the first nickel-chromium wire and the annealing furnace wall can be avoided to prevent wear and damage to the first nickel-chromium wire; the L-shaped second fixing block provides a receiving space between the second fixing block and the annealing furnace, which facilitates the installation and disassembly of the first nickel-chromium wire and the precision stainless steel strip.
[0022] 2. This utility model can seal the inlet and outlet of the annealing furnace with velvet and felt, thus ensuring that the heat inside the annealing furnace can dissipate and without affecting the entry and exit of the precision stainless steel strip into and out of the furnace.

[0039] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0040] like Figures 1 to 6The diagram shows the preferred embodiment of this utility model. The electromechanical threading device of this embodiment includes: a first nickel-chromium wire 1, a driving mechanism 2, and two guiding mechanisms 4. A precision stainless steel strip is mounted on the first nickel-chromium wire 1. The first nickel-chromium wire 1 is wound around the driving mechanism 2, and the driving mechanism 2 passes through the annealing furnace 3. The driving mechanism 2 is used to drive the first nickel-chromium wire 1 to move so that the first nickel-chromium wire 1 drives the precision stainless steel strip through the annealing furnace 3 and undergoes softening treatment in the annealing furnace 3. The two guiding mechanisms 4 are located at both ends of the first nickel-chromium wire 1, and the first nickel-chromium wire 1 abuts against the guiding mechanism 4. The guiding mechanism 4 is used to guide the first nickel-chromium wire 1. Therefore, the first nickel-chromium wire 1 is driven to move by the drive mechanism 2. Compared with the existing manual pulling method, this method has a simple structure, is easy to operate, and can shorten the threading time, thereby improving the production efficiency of precision stainless steel strip. At the same time, through the design of two guide mechanisms 4, the first nickel-chromium wire 1 is guided during its movement. This can avoid friction between the first nickel-chromium wire 1 and the wall of the annealing furnace 3, which would cause wear and damage to the first nickel-chromium wire 1, thereby improving the service life of the first nickel-chromium wire and reducing the production cost of the entire electromechanical threading device.
[0041] In this embodiment, the driving mechanism 2 includes a driving member 201 and a winding roller 202. The driving end of the driving member 201 is connected to one end of the winding roller 202, and the first nichrome wire 1 is wound on the winding roller 202. Thus, the rotation of the winding roller 202 is controlled by the driving member 201 to control the movement of the first nichrome wire 1.
[0042] In this embodiment, the guiding mechanism 4 includes: a first fixing block 401, a guide roller 402, and a second fixing block 403 arranged sequentially from top to bottom. Both the first fixing block 401 and the guide roller 402 are connected to the annealing furnace 3. The two ends of the guide roller 402 are rotatably connected to the first fixing block 401 and the second fixing block 403, respectively. The second fixing block 403 has an L-shaped transverse cross-section. Thus, as... Figure 1 , 2 As shown in Figure 6, the two guide rollers 402 and the winding roller 202 form a stable triangular support structure, so that the first nickel-chromium wire 1 is in a triangular state and passes through the annealing furnace 3 in a straight state. In this way, friction between the first nickel-chromium wire 1 and the wall of the annealing furnace 3 can be avoided, thus preventing the first nickel-chromium wire 1 from being worn and damaged. The L-shaped second fixing block 403 provides a receiving space between the second fixing block 403 and the annealing furnace 3. This receiving space facilitates the installation and disassembly of the first nickel-chromium wire 1 and the precision stainless steel strip.
[0043] In this embodiment, the device further includes a second nickel-chromium wire 5, which passes through the precision stainless steel strip. Both ends of the second nickel-chromium wire 5 are connected to the first nickel-chromium wire 1. The precision stainless steel strip has through holes through which the second nickel-chromium wire 5 passes. Therefore, during the installation of the precision stainless steel strip, it is only necessary to pass the second nickel-chromium wire 5 through the through holes and fix both ends of the second nickel-chromium wire 5 to the first nickel-chromium wire 1.
[0044] In this embodiment, velvet 301 and felt 302 are arranged sequentially from the inside to the outside at both ends of the annealing furnace 3. Thus, the inlet and outlet of the annealing furnace 3 can be sealed by the velvet 301 and felt 302, thereby ensuring that the heat inside the annealing furnace 3 can be dissipated without affecting the entry and exit of the precision stainless steel strip into and out of the furnace.
[0045] In this embodiment, it also includes: a support frame 6 and a base 7. The annealing furnace 3 and the support frame 6 are both installed on the base 7. The driving component 201 is connected to the support frame 6, and the other end of the winding roller 202 is rotatably connected to the support frame 6.
[0046] The softening process of the precision stainless steel strip of this utility model is as follows: First, the precision stainless steel strip to be softened is placed at the inlet of the annealing furnace 3, and the precision stainless steel strip is fixed on the first nickel-chromium wire 1 by the second nickel-chromium wire 5; then, the drive unit 201 and the annealing furnace 3 are started, the drive unit 201 drives the winding roller 202 to rotate, and with the cooperation of the two guide rollers 402, the first nickel-chromium wire 1 moves, so as to transport the precision stainless steel strip to be softened from the inlet to the annealing furnace 3, and the softening treatment takes place in the annealing furnace 3; finally, with the continuous movement of the first nickel-chromium wire 1, the softened precision stainless steel strip is transported from the annealing furnace 3 to the outlet, and the precision stainless steel strip is removed from the first nickel-chromium wire 1, thus completing the softening treatment of the precision stainless steel strip.
[0047] In summary, this utility model drives the first nickel-chromium wire 1 to move through the drive mechanism 2. Compared with the existing manual pulling method, this method has a simple structure, is easy to operate, and can shorten the threading time, thereby improving the production efficiency of precision stainless steel strips. At the same time, through the design of two guide mechanisms 4, the first nickel-chromium wire 1 is guided during its movement. This avoids friction between the first nickel-chromium wire 1 and the wall of the annealing furnace 3, which would cause wear and damage to the first nickel-chromium wire 1, thereby increasing the service life of the first nickel-chromium wire and reducing the production cost of the entire electromechanical threading device.
