Description

Technical Field

[0001] This utility model relates to the field of enameled wire processing equipment, specifically a self-locking and unhooking box cover device. Background Technology

[0002] Cleaning enameled wire with a water cleaning system before annealing is a crucial step to ensure the quality of subsequent annealing and the performance of the enameled wire. The main reasons are as follows: Removing surface oil and impurities to avoid annealing defects; removing residual contaminants from rolling / drawing: Enameled wire production involves rolling and drawing processes, during which lubricants (such as machine oil and emulsions) are used to reduce friction and protect the molds. If these oils remain on the surface of the copper (or aluminum) wire, they will decompose at high temperatures during annealing, producing carbides and volatiles. Carbides adhering to the surface will form black spots and an oxide layer, resulting in a rough wire surface and affecting the adhesion of subsequent coatings. Volatiles accumulating in the annealing furnace may contaminate the furnace body and even enter the cooling system with the wire, causing secondary pollution. During storage and transportation in the workshop, the wire may absorb dust, metal shavings, and other impurities. These impurities may react with copper at high temperatures to form oxide inclusions, reducing the wire's conductivity and mechanical strength.

[0003] A cover is installed on the cleaning tank to ensure the safety of operators when cleaning the inside of the tank or performing bare wire handling inside the tank. The cover is usually fixed by a nitrogen spring. During long-term use, the nitrogen spring is an energy storage element that provides thrust through the expansion force of the internal high-pressure nitrogen (usually 10-15MPa). Its performance directly depends on the integrity of the seal and the nitrogen pressure. During long-term use, the seals (such as sealing rings and guide sleeves) are easily affected by high pressure, friction (when the piston rod extends and retracts), and the cleaning tank environment (water vapor, corrosion from cleaning agents), which will gradually age and wear down, leading to seal failure. After nitrogen leakage, the internal pressure drops, the supporting force decreases accordingly, and the cover is easy to fall off after being pushed up, causing industrial accidents.

[0019] Please see Figure 1-6This utility model provides a self-locking and unhooking box cover device, including a washing box 1, a central seat 2 fixedly connected to the middle of the washing box 1, and a cover 4 installed on both sides of the central seat 2 via hinges 3. The cover 4 covers the washing box 1, and a locking tongue 52 is installed on the cover 4. A lock seat 51 is installed on the central seat 2. The lock seat 51 and the locking tongue 52 are combined to form a self-locking and unhooking mechanism 5. A support seat 510 is provided on the lock seat 51. The bottom of the support seat 510 is bolted to the central seat 2. A support 511 is movably installed on the upper part of the support seat 510. A locking piece 514 is fixedly connected to the end of the support 511. A lock buckle 516 is fixedly provided at the bottom of the lock piece 514. A lock cylinder 523 is engaged inside the lock buckle 516. A locking piece 522 is connected to the end of the lock cylinder 523.

[0020] In a preferred embodiment, the lock base 51 also includes a support stud 512, a connecting pin 513, an inclined surface 515, an upper connecting pin 517, a lower connecting pin 518, a lock cylinder 5181, a mating pin 5182, a spring 519, and a stabilizing plate 500. The connecting pin 513 passes through a through-hole bolt on the end of the support 511 and is connected to the support base 510. The support 511 and the connecting pin 513 are movably connected.

[0021] A support stud 512 is installed on the support base 510. The support stud 512 is supported at the bottom of the support base 511. A bevel 515 is opened at the end of the locking plate 514 away from the support base 511. An upper connecting post 517 is fixedly connected to the surface of the locking plate 514. A stabilizing plate 500 is installed on the surface of the locking plate 514. A connecting post 5182 is fixedly connected to the inner wall of the stabilizing plate 500.

[0022] like Figure 4 , Figure 5 and Figure 6 As shown: the inclined surface 515 is inclined, the locking cylinder 523 is cylindrical, when the outer ring surface of the locking cylinder 523 acts on the inclined surface 515, the locking piece 514 is subjected to force and moves upward. When the locking cylinder 523 moves to the bottom of the locking piece 514, the locking piece 514 moves downward under the action of gravity, so that the latch 516 locks the locking cylinder 523, completing the fixing of the cover plate 4; the bottom of the support 511 is limited and supported by the support stud 512.

[0023] In a preferred embodiment, a lock cylinder 5181 is provided on the docking post 5182, and a lower connecting post 518 is installed on the side of the lock cylinder 5181 away from the docking post 5182. Above the lower connecting post 518 is an upper connecting post 517, and the upper connecting post 517 and the lower connecting post 518 are connected by a spring 519.

[0024] The locking tongue 52 includes a docking seat 521, a locking piece 522 and a locking cylinder 523. The bottom of the locking piece 522 has a slot, and a fixing bolt is inserted inside the slot. The fixing bolt passes through the slot and is bolted to the docking seat 521. The docking seat 521 is "L" shaped, and the bottom of the docking seat 521 is bolted to the cover plate 4.

[0025] like Figure 5 As shown: The distance between the locking piece 522 and the docking seat 521 can be adjusted by the fixing bolt inserted inside the slot. By tightening or loosening the fixing bolt, the locking piece 522 and the docking seat 521 can be fixed or released. In this way, the opening of the cover plate 4 can be adjusted accordingly.

[0026] In a preferred embodiment, the support 511 rotates around the connecting pin 513 as the fulcrum. The lock seat 51 and the lock tongue 52 are connected through the lock cylinder 523 and the lock buckle 516. The lock buckle 516 is C-shaped and has an arc-shaped slot. The lock cylinder 523 is cylindrical.

[0027] like Figure 4 , Figure 5 and Figure 6 As shown: The latch 516 supports the lock cylinder 523 through its arc-shaped slot. When the cover plate 4 is released, the latch 516 and the lock cylinder 523 can lock the cover plate 4 firmly, thus ensuring the stability of the cover plate 4 when it is stationary and preventing the cover plate 4 from accidentally falling and injuring the staff.

[0028] Unpainted bare wires continuously shuttle through the washing tank 1. After being cleaned inside the tank 1, the unpainted bare wires will accumulate dirt over time. When cleaning the inner wall of the tank, the operator needs to open the cover 4. During the opening process, the cover 4 is fixed or released directly by the self-locking hook mechanism 5 to prevent the cover 4 from falling accidentally and causing a safety accident. In addition, when the operator needs to perform the "pulling the wire" operation (pulling the wire: pulling the bare wire from one end of the tank to the other end), the operator also needs to open the cover 4.

[0029] Working principle: When the cover 4 on the washing tank 1 needs to be opened, the cover 4 is installed on both sides of the central seat 2 in the middle of the washing tank 1 via hinges 3. When the cover 4 is opened, the locking tongue 52 on the cover 4 moves, and the locking cylinder 523 at the end of the locking tongue 52 moves towards the locking plate 514. When the locking cylinder 523 collides with the inclined surface 515, the locking plate 514 moves upward under force. At this time, the locking plate 514 and the support 511 can deflect around the connecting pin 513. When the locking cylinder 523 continues to move forward and passes through the latch 516, the locking plate 514 moves downward under the action of gravity, so that the locking cylinder 523 is engaged inside the latch 516, completing the fixing of the cover 4. The opening and closing of the cover 4 is simpler and faster. Furthermore, the fastening method using the latch 516 and locking cylinder 523 provides higher security, making it less likely for the cover plate 4 to fall accidentally. This replaces the connection method using a nitrogen spring, freeing up both hands for operation and ensuring the safety of operators when cleaning enameled wires inside the washing chamber 1. After cleaning, the cover plate 4 is pushed forward, and the locking cylinder 523 on the cover plate 4 continues to move forward, allowing the locking cylinder 523 to pass through the receiving space between the lower connecting column 518 and the locking piece 514, while simultaneously pressing down on the lower connecting column 518. As the lower connecting column 518 moves downward, it compresses the spring 519. When the locking cylinder 523 disengages from the lower connecting column 518, the spring 519 returns to its original position, completing the unhooking of the cover plate 4, allowing the cover plate 4 to cover the washing chamber 1 again.
