Description

Technical Field

[0001] This utility model relates to the technical field of box-type annealing furnaces, and in particular to a wire rod annealing rack for a box-type annealing furnace. Background Technology

[0002] The box-type annealing furnace wire rod annealing rack is a device used to support and fix wire rods during the annealing process. Its design and use are crucial for ensuring annealing quality, improving production efficiency and safety.

[0003] Chinese patent document CN222434528U discloses a fastener coil annealing rack, including a feed rack and a feed rack. Both the feed rack and the feed rack include cylindrical support cylinders. A circular base plate is fixed to the bottom of each support cylinder, with the inner hole of the base plate smaller than the inner hole of the support cylinder. The height of the feed rack is less than 1.8m, and the height of the feed rack is less than 1.5m. The feed rack is stacked on top of the feed rack. Multiple conical stiffening plates are vertically fixed to the inner wall of the support cylinder of the feed rack. Several vertical stiffening ribs are provided at the upper end of the conical stiffening plates. Several ventilation holes are provided on the support cylinders of both the feed rack and the feed rack. A lifting mechanism is provided at the top of both the feed rack and the feed rack. This utility model solves the problem in the prior art where multiple coils of raw material are placed on one rack during annealing, causing the bottom support plate of the rack to easily deform and be damaged during long-term use, making it difficult to stably place and support the raw material.

[0004] The existing technology has the following problems:

[0005] The support cylinder and the base plate on the annealing material rack are fixedly connected. When the material is placed into the annealing furnace, multiple wire rod materials are often attached to the outside of one support cylinder. Since the weight of each wire rod material can reach several tons, it is difficult to remove the material from the outside of the support cylinder, which may cause bumps or collisions with the lifting equipment and shaking of the material rack. Utility Model Content

[0006] This invention provides a box-type annealing furnace wire rod annealing rack to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A box-type annealing furnace wire rod annealing rack includes a chassis, a central cylinder movably sleeved on the inner side of the chassis, a number of annularly distributed support feet fixedly connected to the lower side of the chassis near the edge, a fixing mechanism fixedly connected to the upper and lower sides of the central cylinder, a reinforcing ring fixedly connected to the upper side of the chassis near the inner edge, and a number of annularly distributed vent holes opened on the outer side of the central cylinder.

[0009] The fixing mechanism includes a support base, the upper side of which is fixedly connected to the lower side of the central cylinder near the inner edge. Several ring-shaped support plates are fixedly connected to the outer side of the support base near the upper side. A pick-and-place slot is provided on the upper side of the chassis near the inner edge.

[0010] Preferably, each of the trays has an insertion hole at the center of its upper side, and a number of ring-shaped insertion rods are fixedly connected to the lower side of the chassis near its inner edge, with the outer side of each insertion rod movably sleeved on the inner side of the insertion hole.

[0011] Preferably, a number of annularly distributed inclined platforms are fixedly connected to the lower side of the chassis near the outer edge.

[0012] Preferably, a plurality of ring-shaped blocks are fixedly connected to the lower side of the chassis.

[0013] Preferably, a first chamfer is provided on the bottom side of each of the several blocks near the pick-up / placement slot.

[0014] Preferably, a fixing seat is fixedly connected to the upper side of the central cylinder near the outer edge, and the upper side of the fixing seat is provided with a plurality of annularly distributed placement grooves, and the upper side of the placement groove is provided with a second chamfer near the edge.

[0015] Preferably, soft graphite felt is provided on the upper side of several of the trays, the upper side of the fixing seat, and the lower inner surface of several mounting slots.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model provides a box-type annealing furnace wire rod annealing rack. Based on the cooperation of the chassis, central cylinder, fixing mechanism, support base, pallet, pick-up and drop slot, insertion hole, insertion rod, stop block, first cutting angle and inclined platform, the chassis is lifted by a hydraulic lifting device and then rotated so that the pick-up and drop slot is aligned with the pallet. This allows the central cylinder to be directly lifted and the chassis and central cylinder to be separated, thereby allowing the wire rod raw material to be quickly removed from the central cylinder, achieving the purpose of rapid unloading.

[0018] 2. This utility model provides a box-type annealing furnace wire rod annealing rack. Based on the cooperation of the chassis, central cylinder, fixing mechanism, support seat, tray, fixing seat, placement groove and second chamfer, multiple annealing racks are stacked on each other, and the support seat and fixing seat are adjusted to avoid the problem of a single annealing rack being subjected to a large weight. At the same time, it avoids the problem of the components being misaligned and unstable due to direct stacking. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5 As shown, a box-type annealing furnace wire rod annealing rack includes a base plate 1, a central cylinder 2 movably sleeved on the inner side of the base plate 1, a number of annularly distributed support feet 3 fixedly connected to the lower side of the base plate 1 near the edge, a fixing mechanism 4 fixedly connected to the upper and lower sides of the central cylinder 2, a reinforcing ring 5 fixedly connected to the upper side of the base plate 1 near the inner edge, and a number of annularly distributed vent holes 6 opened on the outer side of the central cylinder 2.

[0027] The fixing mechanism 4 includes a support base 41. The upper side of the support base 41 is fixedly connected to the lower side of the central cylinder 2 near the inner edge. Several ring-shaped trays 42 are fixedly connected to the outer side of the support base 41 near the upper side. A pick-and-place slot 43 is opened on the upper side of the chassis 1 near the inner edge.

[0028] It should be noted that the structural design of the chassis 1 and the central cylinder 2 is consistent with that of the components with the same function in the reference case. When assembling the chassis 1 and the central cylinder 2, the chassis 1 is fitted onto the outside of the central cylinder 2 from the top, so that the support plate 42 and the pick-and-place slot 43 are misaligned. This allows the support plate 42 to lift the chassis 1 when the central cylinder 2 is lifted. When the chassis 1 and the central cylinder 2 are disassembled, the chassis 1 can be lifted and then rotated so that the support plate 42 is aligned with the pick-and-place slot 43, allowing the central cylinder 2 to be lifted and directly removed from the chassis 1.

[0029] like Figure 4 As shown, several trays 42 have insertion holes 44 in the middle of their upper sides. Several ring-shaped insertion rods 45 are fixedly connected to the lower side of the chassis 1 near the inner edge. The outer side of the insertion rods 45 is movably sleeved on the inner side of the insertion holes 44.

[0030] It should be noted that the insert rod 45 is inserted into the inside of the insertion hole 44 to limit the chassis 1 and the center cylinder 2, so that the chassis 1 and the center cylinder 2 cannot rotate relative to each other.

[0031] like Figure 2 As shown, several ring-shaped inclined platforms 411 are fixedly connected to the lower side of the chassis 1 near the outer edge.

[0032] It should be noted that the structure of the inclined platform 411 allows the inclined platform 411 to be pushed by a push rod, causing the chassis 1 to rise.

[0033] like Figure 4 As shown, several ring-shaped blocks 46 are fixedly connected to the lower side of the chassis 1.

[0034] It should be noted that the side of the blocks 46 that is far apart from each other is coplanar with the inner side of the pick-and-place slot 43 that is close to the blocks 46, so that when the tray 42 is in contact with the side of the blocks 46, the tray 42 and the pick-and-place slot 43 are perfectly aligned.

[0035] like Figure 4 As shown, a first chamfer 47 is provided on the bottom side of several blocks 46 near the pick-up and put-down slot 43.

[0036] It should be noted that the first chamfer 47 is set to prevent the chassis 1 from rotating excessively, which would cause the bottom of the stop block 46 to overlap with the upper side of the support plate 42 when the chassis 1 is lowered again, resulting in interference with the support plate 42.

[0037] like Figure 5 As shown, a fixing seat 48 is fixedly connected to the upper side of the central cylinder 2 near the outer edge. Several annularly distributed mounting grooves 49 are provided on the upper side of the fixing seat 48, and a second chamfer 410 is provided on the upper side of the mounting grooves 49 near the edge.

[0038] It should be noted that when multiple annealing racks are stacked on top of each other, the support base 41 of the upper annealing rack is movably sleeved on the inner side of the fixed base 48, and the tray 42 is movably sleeved on the inner side of the placement groove 49. The second chamfer 410 is used to avoid interference at the edge with the movement of the support base 41 and the tray 42.

[0039] like Figure 5 As shown, soft graphite felt is provided on the upper side of several trays 42, the upper side of the fixing seat 48, and the lower inner surface of several mounting slots 49.

[0040] It should be noted that the soft graphite felt has high temperature resistance and is a soft material, which prevents collisions between multiple annealing racks when they are stacked or installed between the base 1 and the center cylinder 2.

[0041] The working principle of this utility model is as follows: First, when assembling the chassis 1 and the center cylinder 2, the chassis 1 is sleeved onto the outside of the center cylinder 2 from the top, so that the support plate 42 and the pick-and-place slot 43 are misaligned. This allows the support plate 42 to lift the chassis 1 when the center cylinder 2 is lifted. When the chassis 1 and the center cylinder 2 are disassembled, the chassis 1 can be lifted and then rotated so that the support plate 42 is aligned with the pick-and-place slot 43, allowing the center cylinder 2 to be lifted and directly removed from the chassis 1. The insertion rod 45 is inserted into the inner side of the insertion hole 44 to limit the chassis 1 and the center cylinder 2, preventing relative rotation between them. The chassis 1 is lifted by a hydraulic lifting device and then rotated so that the pick-and-place slot 43 is aligned with the support plate 42, allowing the center cylinder 2 to be lifted directly. This separates the chassis 1 and the center cylinder 2, thus allowing the wire rod to be removed. The raw material is quickly removed from the central cylinder 2 to achieve rapid unloading. Finally, when multiple annealing racks are stacked, the support base 41 of the upper annealing rack is movably sleeved on the inner side of the fixed base 48, and the support plate 42 is movably sleeved on the inner side of the placement groove 49. The second chamfer 410 is used to avoid interference at the edge with the movement of the support base 41 and the support plate 42. The soft graphite felt has high temperature resistance and is a soft material, so that when multiple annealing racks are stacked or installed between the chassis 1 and the central cylinder 2, collisions are avoided. By stacking multiple annealing racks, the support base 41 and the fixed base 48 are adjusted to avoid the problem of a single annealing rack being subjected to a large weight. At the same time, it avoids the problem of the parts being misaligned and unstable due to direct stacking.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
