Sealing annealing device for wire and cable production

Abstract

This utility model relates to the field of wire and cable manufacturing technology, and provides a sealing annealing treatment device for wire and cable production, including: an annealing chamber, a sealing plate, a support mechanism, and a translation mechanism. The sealing annealing treatment device for wire and cable production provided by this utility model forms a first seal through a high-temperature resistant silicone sealing ring on the inner side of the sealing plate and an annular groove on the opening surface of the annealing chamber. Through the compression action of a telescopic cylinder, the sealing ring undergoes elastic deformation to fill the gap between the contact surfaces, effectively preventing external air from entering and preventing cable oxidation during annealing. The slot formed by the boss, the stop bar, and the inner wall of the gantry, in conjunction with the telescopic cylinder, constitutes a second mechanical seal. The locking structure restricts the lateral displacement of the sealing plate, further enhancing the sealing reliability. Furthermore, the slot width is slightly larger than the boss thickness, allowing the sealing plate to be finely positioned during closure, compensating for manufacturing errors or dimensional changes caused by thermal expansion, and ensuring that the sealing ring is always in an optimal compression state.

Description

Technical Field

[0001] This utility model relates to the field of wire and cable production technology, specifically to a sealing annealing treatment device for wire and cable production. Background Technology

[0002] A cable is an electrical or signal transmission device, typically consisting of several or groups of conductors (each group containing at least two conductors) twisted together in a rope-like manner. Each group of conductors is insulated from each other and is often twisted around a central core, with the entire cable covered by a highly insulating outer layer.

[0003] Traditional annealing equipment has a simple sealing structure. Under high temperature and pressure fluctuations, tiny gaps easily form on the sealing surface, allowing oxygen to seep in, causing the cable surface to oxidize, reducing conductivity and mechanical strength. At the same time, traditional sealing plates are only fixed by vertical guide rails or cylinders, lacking lateral restraint. Under the impact of gas pressure or mechanical vibration in the annealing chamber, the sealing plates are prone to lateral displacement, disrupting the alignment between the sealing ring and the groove, and causing local leakage. To address these issues, we propose a sealing annealing treatment device for wire and cable production. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide a sealing annealing treatment device for wire and cable production, which solves the technical problems of sealing annealing treatment devices for wire and cable production in related technologies / prior technologies.

[0005] According to one aspect, at least one embodiment of the present invention provides a sealed annealing treatment apparatus for wire and cable production, comprising: an annealing chamber, a sealing plate, a support mechanism, and a translation mechanism; The support mechanism includes a gantry frame, auxiliary pulleys, slings, a winch body, a U-shaped base, a T-shaped guide rail, and an angle plate. The gantry frame is fixed to the opening side of the annealing box by the angle plate. The sealing plate is slidably installed on the inner side of the gantry frame. The winch body is installed on the top surface of the annealing box. Its slings pass around the auxiliary pulleys and connect to the U-shaped base. The U-shaped base is slidably connected to the T-shaped guide rail. The U-shaped base and the sealing plate are linked by a translation mechanism. The translation mechanism includes a telescopic cylinder, a stop bar, a boss and a reinforcing plate. The piston rod of the telescopic cylinder is connected to the sealing plate through the reinforcing plate. The boss and the sealing plate are integrally formed. The stop bar is set on the inner wall of the gantry frame. The boss is inserted into the slot formed by the stop bar and the inner wall of the gantry frame. A sealing ring is provided on the inner side of the sealing plate. When closed, the sealing ring is engaged with the notch of the annealing box opening and is squeezed by the telescopic cylinder to fill the gap of the contact surface.

[0006] For example, in a sealed annealing treatment device for wire and cable production provided in at least one embodiment of the present invention, the gantry frame and the annealing box are fixedly connected by two corner plates. The corner plates are in the form of right-angled triangles, and their right-angled sides are respectively welded to the back of the gantry frame and the side wall of the annealing box.

[0007] For example, at least one embodiment of the present invention also provides a sealing annealing treatment device for wire and cable production, wherein the T-shaped guide rail is provided along the vertical direction of the gantry frame, and the end face of the U-shaped seat is provided with a groove that matches the T-shaped guide rail.

[0008] For example, in the sealing annealing treatment device for wire and cable production provided in at least one embodiment of the present invention, the winch body is an electric winch, the sling is a steel wire rope, and the preload of the sling is adjusted by the brake of the winch body.

[0009] For example, in the sealing annealing treatment device for wire and cable production provided in at least one embodiment of the present invention, the reinforcing plate is a square steel plate, and the end of the piston rod of the telescopic cylinder is provided with a flange connected to the reinforcing plate.

[0010] For example, in the sealing annealing treatment device for wire and cable production provided in at least one embodiment of the present invention, the baffle is fixed to the inner wall of the gantry by welding, and a slot is provided between the end face of the baffle and the inner wall of the gantry. The width of the slot is greater than the thickness of the boss, so as to allow fine-tuning of the positioning when the sealing plate is closed.

[0011] For example, in the sealing annealing treatment device for wire and cable production provided in at least one embodiment of this utility model, the sealing ring is made of high-temperature resistant silicone and has a trapezoidal cross-section.

[0012] For example, in the sealing annealing treatment apparatus for wire and cable production provided in at least one embodiment of the present invention, the notch on the opening surface of the annealing box is an annular groove that matches the sealing ring.

[0013] The beneficial effects of this utility model are as follows: In this invention, the high-temperature resistant silicone sealing ring on the inner side of the sealing plate forms the first seal with the annular groove on the opening surface of the annealing chamber. Through the squeezing action of the telescopic cylinder, the sealing ring undergoes elastic deformation to fill the gap between the contact surfaces, effectively blocking external air from entering and preventing cable oxidation during the annealing process. The slot formed by the boss, the stop bar, and the inner wall of the gantry, together with the telescopic cylinder, constitutes the second mechanical seal. The locking structure restricts the lateral displacement of the sealing plate, further enhancing the sealing reliability. Moreover, the slot width is slightly larger than the boss thickness, allowing the sealing plate to be finely positioned when closed, compensating for manufacturing errors or dimensional changes caused by thermal expansion, and ensuring that the sealing ring is always in the optimal compression state.

[0022] like Figures 1-4 As shown, it illustrates a sealing annealing treatment device for wire and cable production according to an embodiment of the present invention, including an annealing box 1, a sealing plate 2, a support mechanism 3, and a translation mechanism 4.

[0023] In some examples, the support mechanism 3 includes a gantry frame 31, auxiliary pulleys 32, slings 33, a winch body 34, a U-shaped base 35, a T-shaped guide rail 36, and corner plates 37. The gantry frame 31 is fixed to the opening side of the annealing box 1 via the corner plates 37. The sealing plate 2 is slidably installed on the inner side of the gantry frame 31. The winch body 34 is installed on the top surface of the annealing box 1, and its slings 33 pass around the auxiliary pulleys 32 and connect to the U-shaped base 35. The U-shaped base 35 is slidably connected to the T-shaped guide rail 36, and the U-shaped base 35 and the sealing plate 2 are linked by a translation mechanism 4. The gantry frame 31 and the annealing box 1 are fixedly connected by two corner plates 37. The corner plates 37 have a right-angled triangular structure, and their right-angled sides are welded to the back of the gantry frame 31 and the side wall of the annealing box 1, respectively. The T-shaped guide rail 36 is installed along the vertical direction of the gantry frame 31, and the end face of the U-shaped base 35 has an opening that connects to the T-shaped guide rail 37. The guide rail 36 is matched with a groove. The winch body 34 is an electric winch. The sling 33 is a steel wire rope, and the preload of the sling 33 is adjusted by the brake of the winch body 34. The right-angled sides of the right-angled triangular plate 37 are welded to the back of the gantry 31 and the side wall of the annealing box 1, respectively. The stability of the triangular structure effectively disperses the weight of the sealing plate 2 borne by the gantry 31 and the gas pressure inside the box during the annealing process, avoiding the weld cracking or deformation caused by long-term stress at the connection between the gantry 31 and the annealing box 1. At the same time, the U-shaped seat 35 is slidably connected to the T-shaped guide rail 36 through the groove. The vertical design of the T-shaped guide rail 36 restricts the lateral displacement of the U-shaped seat 35, ensuring that the sealing plate 2 is always aligned with the opening of the annealing box 1 during the lifting process, avoiding the misalignment of the sealing ring 5 and the annular groove due to offset, which may cause local leakage.

[0024] In some examples, the translation mechanism 4 includes a telescopic cylinder 42, a stop bar 43, a boss 44, and a reinforcing plate 41. The piston rod of the telescopic cylinder 42 is connected to the sealing plate 2 via the reinforcing plate 41. The boss 44 is integrally formed with the sealing plate 2. The stop bar 43 is located on the inner wall of the gantry frame 31, and the boss 44 engages with the slot formed by the stop bar 43 and the inner wall of the gantry frame 31. The reinforcing plate 41 is a square steel plate. The end of the piston rod of the telescopic cylinder 42 is provided with a flange that connects to the reinforcing plate 41. The stop bar 43 is fixed to the inner wall of the gantry frame 31 by welding, and a slot is provided between the end face of the stop bar 43 and the inner wall surface of the gantry frame 31. The width of the slot is greater than the thickness of the boss 44 to allow for fine-tuning of the positioning when the sealing plate 2 is closed. The first elastic seal is achieved when the telescopic cylinder 42 pushes the sealing plate 2 to close. Its piston rod transmits pressure to the sealing plate 2 through the reinforcing plate 41, causing the high-temperature resistant silicone sealing ring 5 on the inner side to be squeezed and elastically deformed, filling the microscopic gap between the sealing plate 2 and the annealing box 1, blocking external air from entering and preventing cable oxidation. The second mechanical locking seal is formed by the slot formed by the boss 44, the stop bar 43, and the inner wall of the gantry 31. The slot width is larger than the thickness of the boss 44, allowing the sealing plate 2 to be finely positioned when closed. At the same time, mechanical interference restricts the lateral displacement of the sealing plate 2, preventing the sealing ring 5 from separating from the annular groove due to vibration or pressure impact, further improving the sealing reliability.

[0025] In some examples, a sealing ring 5 is provided on the inner side of the sealing plate 2. When closed, the sealing ring 5 is engaged with the notch of the opening surface of the annealing box 1 and is squeezed by the telescopic cylinder 42 to fill the gap of the contact surface. The sealing ring 5 is made of high temperature resistant silicone with a trapezoidal cross-section. The notch of the opening surface of the annealing box 1 is an annular groove that matches the sealing ring 5. The trapezoidal cross-section design of the sealing ring 5 causes it to deform non-uniformly when under pressure, with the deformation at the bottom being greater than that at the top, forming a "wedge" sealing effect, which better fills the micro-protrusions of the annular groove. At the same time, the inclined side of the trapezoidal structure can guide the gas pressure to be evenly distributed, avoiding local high pressure that could lead to sealing failure. Meanwhile, the high temperature resistant silicone material can still maintain elasticity in the high temperature environment of annealing, avoiding the hardening and cracking of traditional rubber seals at high temperatures, and ensuring long-term sealing reliability.

[0026] This embodiment provides a support mechanism 3 and a translation mechanism 4. The gantry frame 31 in the support mechanism 3 slides the sealing plate 2 onto the opening of the annealing box 1. The telescopic cylinder 42 in the translation mechanism 4 connects the sealing plate 2 to the U-shaped seat 35. An angle plate 37 increases the contact area between the gantry frame 31 and the annealing box 1 to improve the overall structural stability. Therefore, after starting the winch body 34 mounted on the top surface of the annealing box 1, the hoisting cable 33 is wound up. The hoisting cable 33 passes around the auxiliary pulley 32 at the top of the gantry frame 31, pulling the U-shaped seat 35 upwards along the T-shaped guide rail 36 on the surface of the gantry frame 31. The sealing plate 2, connected to the U-shaped seat 35 by the telescopic cylinder 42, also slides upwards along the gantry frame 31, opening the annealing box 1. After placing the electrical wires and cables inside the annealing box 1, the winch body 34 is then used to... The preload of the sling 33 is gradually reduced. Under the weight of the sealing plate 2, it slides down the gantry 31 until the sealing plate 2 blocks the opening of the annealing box 1. Then, the telescopic cylinder 42 is activated, and its piston rod pushes the sealing plate 2 towards the annealing box 1. At this time, the protrusion 44, which is integrally formed with the sealing plate 2, can be inserted into the slot formed between the stop strip 43 and the inner wall of the gantry 31. The sealing ring 5 on the inner side of the sealing plate 2 is inserted into the notch of the opening surface of the annealing box 1. Under the force of the telescopic cylinder 42, the sealing ring 5 is also squeezed, filling the gap between the sealing plate 2 and the contact surface of the annealing box 1, thereby ensuring the sealing degree of the entire annealing box 1 after the sealing plate 2 is closed, so as to meet the annealing requirements of wires and cables. At the same time, a reinforcing plate 41 is set at the connection between the sealing plate 2 and the piston rod of the telescopic cylinder 42 to improve the structural strength of the sealing plate 2.
