Description

Technical Field

[0001] The invention relates to the technical field of heat treatment of steel wire ropes, and in particular to a heat treatment device for steel wire ropes. Background Art

[0002] The main varieties of steel wire ropes include phosphate coated steel wire ropes, galvanized steel wire ropes, stainless steel wire ropes and smooth steel wire ropes, which are made of wire rods and rope cores as the main materials and grease as the auxiliary materials. In the steel wire rope production process, the most critical links are wire drawing, heat treatment and wire rope production. Among them, heat treatment is to improve the internal structure of steel wire, so that the steel wire has excellent drawing performance, and it is also an important process that determines the mechanical properties of steel wire. Strengthening the technical management of heat treatment process and heat treatment operation is the key to improving the quality of steel wire.

[0003] Annealing is a metal heat treatment process that heats the metal to a certain temperature, keeps it for a sufficient time, and then cools it at an appropriate speed, usually slowly, and sometimes controlled cooling. Its purpose is to reduce the hardness of the metal and improve machinability; reduce residual stress, stabilize size, reduce deformation and crack tendency; refine grains, adjust structure, eliminate structural defects; make the material structure and composition uniform, and improve material properties.

[0004] During the heat treatment process of the steel wire rope, it is necessary to perform annealing treatment on it. Most of the steel wire rope heat treatment equipment in the prior art anneals the steel wire rope after stretching and forming through an annealing furnace. In order to improve the processing efficiency, when the steel wire rope is sent into the annealing furnace, multiple strands of steel wire rope will be arranged side by side and annealed simultaneously through the annealing furnace. The disadvantage of this solution is that it is not convenient to distribute the multiple strands of steel wire rope in a centralized manner. Due to the difference in temperature at different positions in the annealing furnace, the annealing effects of the multiple strands of steel wire rope arranged side by side are different, which affects the mechanical properties of the finished steel wire rope.

[0037] like Figures 1 to 13 As shown: A heat treatment device for steel wire ropes includes an annealing furnace 1. The annealing furnace 1 includes a furnace body 10, a base 11 and a pair of door bodies 12. The bottom of the furnace body 10 is fixedly connected to the top of the base 11. The two door bodies 12 are respectively hinged to the two ends of the furnace body 10. Through the holes in the door bodies 12, the steel wire rope body 13 is passed through the door body 12, thereby passing through the furnace body 10, and annealing the steel wire rope through the furnace body 10. The steel wire rope body 13 can be subjected to assembly line annealing operation in cooperation with a winding mechanism. It also includes a pair of centralized tightening components 2, a driving component 3 and a resistance adjustment component 4. The two centralized tightening components 2 are respectively installed on the two door bodies 12, so that the two centralized tightening components 2 work simultaneously, tightening the parts of multiple steel wire rope bodies 13 passing through the furnace body 10 to the outer periphery of the shell, and distributing them in a circular pattern, so that the annealing temperature of the steel wire rope body 13 is relatively balanced, and the stress performance of the steel wire rope body 13 is improved. The centralized tightening assembly 2 includes a shell 20, a plurality of arc blocks 21, a plurality of bandages 22, a plurality of snap rings 23, a tightening mechanism 24, a lifting mechanism 25 and a blocking mechanism 26. One end of the shell 20 is fixedly connected to the door body 12. The plurality of arc blocks 21 are symmetrically distributed on both sides of the shell 20. A plurality of semicircular grooves 200 are provided on the periphery of the shell 20. A groove 210 is provided on the top of the arc block 21. The groove 210 and the semicircular groove 200 form an annular structure. The two arc blocks 21 are rotatably connected through the bandage 22. The bottom of both sides of the shell body are rotatably connected to the arc block 21 through the bandage 22. One end of the snap ring 23 is fixedly connected to the arc block 21. A plurality of penetrating arc grooves 120 are provided on one side of the door body 12. The periphery of the snap ring 23 is slidably connected to the arc groove 120. The snap ring 23 and The outer periphery of the wire rope body 13 is rotatably connected. When the wire rope body 13 is annealed, multiple wire rope bodies 13 are respectively passed through multiple clamping rings 23, and the outer periphery of the wire rope body 13 is fitted with the groove 210. Then, the arc blocks 21 on both sides are driven to move through the tightening mechanism 24. As the tightening mechanism 24 continues to work, the remaining arc blocks 21 are driven by the bandage 22. At the same time, the clamping ring 23 slides along the arc groove 120, so that the multiple arc blocks 21 are moved in sequence to fit with the outer periphery of the shell. At this time, the outer periphery of the wire rope body 13 is fitted with the semicircular groove 200, and multiple arc blocks 21 and bandages 22 are wrapped around the outer periphery of the shell, thereby driving multiple wire rope bodies 13 to move to the outer periphery of the shell, so that the part of the wire rope body 13 located in the furnace body 10 is distributed in a circle and heated evenly. The tightening mechanism 24 includes a pair of steel cables 240, one end of which is rotatably connected to the opposite side of the two arc blocks 21 on both sides, a lifting mechanism 25 is installed on the shell, and the lifting mechanism 25 is used to increase the position of the bending part of the steel cables 240, and a blocking mechanism 26 is installed on the door body 12. The two mechanisms are used to block the arc groove 120. When the clamp ring 23 is located at the bottom of the arc groove 120, multiple arc blocks 21 are horizontally distributed at the bottom of the shell, and it is convenient to pass multiple steel wire rope bodies 13 through the arc blocks 21 to fix them. When the clamp ring 23 is located at the top of the arc groove 120, multiple arc blocks 21 are circumferentially distributed around the shell.At this time, the portion of the steel wire rope body 13 located in the furnace body 10 is distributed in a circular pattern.

[0038] like Figures 1 to 13 As shown: The tightening mechanism 24 also includes a capstan 241 and a rotating shaft 242. The capstan 241 is coaxially connected to the outer periphery of the rotating shaft 242. The rotating shaft 242 is rotatably connected to the inner wall of the shell. The other end of the steel cable 240 passes through the side wall of the shell and is fixedly connected to the outer periphery of the capstan 241. The capstan 241 is rotated to reel in the steel cable 240. The steel cable 240 is shortened and one end of the steel cable 240 drives the arc blocks 21 on both sides to move, thereby driving the arc blocks 21 and the bandage 22 to fit the outer periphery of the shell, completing the centralized tightening of the steel wire rope body 13.

[0039] like Figures 1 to 10 As shown: The lifting mechanism 25 includes a sleeve 250 and a pair of tension springs 251. The bottom of the sleeve 250 passes through the top wall of the shell and is slidably connected thereto. Both sides of the top of the sleeve 250 are arc-shaped structures. The steel cable 240 passes through the sleeve 250 and contacts the top thereof. Two tension springs 251 are symmetrically distributed at both ends of the sleeve 250. One end of the tension spring 251 is fixedly connected to the top wall of the shell 20, and the other end of the tension spring 251 is fixedly connected to the bottom of the sleeve 250. When the steel cable 240 is loosened, the arc block 21 returns to a horizontal distribution, and the sleeve 250 slides upward by the tension provided by the tension spring 251, pushing the steel cable 240 upward to avoid friction between the steel cable 240 and the outer periphery of the shell, so that the multiple arc blocks 21 are reset in sequence to avoid contact between multiple wire rope bodies 13. When the steel cable 240 is tightened, as the arc block 21 fits against the outer periphery of the shell, the sleeve 250 is squeezed by the steel cable 240 and moves downward, so that the tension spring 251 is stretched, thereby ensuring that the two arc blocks 21 at the top are fully fitted with the outer periphery of the shell.

[0040] like Figures 1 to 10 As shown: The lifting mechanism 25 also includes a block 252, a pair of racks 253, a gear 254, a push block 255 and a pair of thrust springs 256. The push block 255 passes through the side wall of the shell and is slidably connected thereto. One end of the push block 255 is in conflict with one of the bandages 22. The gear 254 is rotatably connected to the inner wall of the shell. The two racks 253 are symmetrically distributed on the top and bottom of the gear 254 and mesh with the gear 254. One of the racks 253 is fixedly connected to the other end of the push block 255, and the other rack 253 is fixedly connected to the block 252. The block 252 is snap-fitted with the bottom of the sliding sleeve 250. The thrust spring 256 is installed in the shell. The thrust spring 256 is used to provide horizontal thrust to the push block 255. When the sleeve 250 rises to the top, the thrust spring 256 pushes out the push block 255 to make it move horizontally, driving the rack 253 to move. At the same time, through the meshing transmission between the rack 253 and the gear 254, the two racks 253 move in opposite directions, pushing the clamping block 252 to engage with the bottom of the sleeve 250, so that the sleeve 250 is stably at the top. When the steel cable 240 is wound, the arc block 21 fits with the shell in turn. When the bandage 22 and the push block 255 collide with each other, they are pushed to slide into the shell, so that the clamping block 252 is separated from the bottom of the sleeve 250. At this time, the sleeve 250 slides into the shell, ensuring that multiple steel wire rope bodies 13 move in sequence.

[0041] like Figures 1 to 7 As shown: Two thrust springs 256 are symmetrically distributed at both ends of the rack 253 at the bottom, so that the sliding sleeve 250 is balanced and moves stably. One end of the thrust spring 256 is fixedly connected to the push block 255, and the other end of the thrust spring 256 is fixedly connected to the inner wall of the shell. When the push block 255 slides into the shell, the thrust spring 256 is compressed, and the clamping block 252 is clamped with the bottom of the sliding sleeve 250. When the bandage 22 is separated from the push block 255, the thrust spring 256 rebounds to provide horizontal thrust to the push block 255, so that the clamping block 252 is separated from the sliding sleeve 250.

[0042] like Figures 1 to 13 As shown: The blocking mechanism 26 includes a plurality of chain plates 27 and a plurality of return springs 28. The top of the chain plate 27 is fixedly connected to one end of the snap ring 23, the bottom of the chain plate 27 is fixedly connected to the bottom of the arc groove 120, one end of the return spring 28 is fixedly connected to the top of the chain plate 27, and the other end of the return spring 28 is fixedly connected to the bottom of the chain plate 27. When the arc block 21 slides up along the arc groove 120, the return spring 28 is stretched, and the chain plate 27 moves with the arc block 21 and blocks the arc groove 120, thereby preventing the temperature in the furnace body 10 from leaking through the arc groove 120. When the steel cable 240 is relaxed, the return spring 28 rebounds and drives the arc block 21 to slide and reset along the arc groove 120, so that it returns to horizontal distribution.

[0043] like Figures 1 to 13 As shown: The chain plate 27 includes a plurality of arc plates 270 and a plurality of connecting rods 272. The arc plates 270 are slidably connected to the arc groove 120. The plurality of arc plates 270 are arranged in an interlaced manner. One side of two adjacent arc plates 270 is hinged to each other. A pair of slide grooves 271 are provided at one end of the arc plate 270. The two ends of the connecting rod 272 are slidably connected to the slide grooves 271 on the two arc plates 270, respectively. The top arc plate 270 is fixedly connected to the snap ring 23, and the bottom arc plate 270 is fixedly connected to the bottom of the arc groove 120. The two arc plates 270 can rotate relative to each other, and the connecting rod 272 slides in the slide groove 271, so that the two arc plates 270 are always connected while rotating relative to each other, so that the chain plate 27 can be unfolded and conform to the shape of the arc groove 120, so that when the snap ring 23 moves upward, the chain plate 27 is unfolded to block the arc groove 120, and when the snap ring 23 moves downward, the chain plate 27 is retracted.

[0044] like Figures 1 to 11 As shown: The driving assembly 3 includes a motor 30, two groups of pulleys 31 and a transmission rod 32. One end of the motor 30 is fixedly connected to one of the door bodies 12. The output shaft of the motor 30 passes through the door body 12 and is coaxially connected to one end of the rotating shaft 242. The two groups of pulleys 31 are respectively installed on the two door bodies 12. The other end of the rotating shaft 242 passes through the door body 12 and is coaxially connected to the pulley 31. The other two pulleys 31 are coaxially connected to the two ends of the transmission rod 32 respectively. The outer periphery of the transmission rod 32 is rotatably connected to the base 11. The two pulleys 31 on the door body 12 are driven by a belt. When the motor 30 is powered on, its output shaft drives one of the rotating shafts 242 to rotate, and at the same time drives one of the pulleys 31 to rotate. The two pulleys 31 are driven by a belt, thereby driving the pulley 31 at the bottom to rotate, and then driving the transmission rod 32 to rotate, and at the same time, another group of pulleys 31 drives another rotating shaft 242 to rotate, thereby driving the two centralized tightening assemblies 2 to work at the same time.

[0045] like Figures 1 to 11 As shown: The resistance adjustment assembly 4 includes a pair of rollers 40, the two rollers are spaced apart from each other, the rollers 40 are rotatably connected to the base 11, and the opposite sides of the two rollers 40 are in contact with the outer periphery of the wire rope body 13. The wire rope body 13 is passed between the two rollers 40, and the wire rope body 13 is clamped by the two rollers 40, which can play a fixing role. At the same time, the rollers 40 can rotate with the movement of the wire rope body 13, so as to realize the assembly line heat treatment of the wire rope body 13.

[0046] like Figures 1 to 11 As shown: The resistance adjustment assembly 4 also includes a pair of resistance discs 41 and a hydraulic rod 42. One end of the hydraulic rod 42 is fixedly connected to the base 11, and the telescopic end of the hydraulic rod 42 is fixedly connected to one of the resistance discs 41. The protrusions on the two resistance discs 41 are in contact with each other, and the other resistance disc 41 is coaxially connected to one side of the top roller. When the hydraulic rod 42 is operated, one of the resistance discs 41 is pushed closer to the other resistance disc 41. The protrusions on the two resistance discs 41 are in contact with each other to increase the friction force, which can increase the friction force of the roller 40 on the wire rope body 13, so that the wire rope body 13 remains taut and the annealing effect is improved.
