Description

Technical Field

[0001] This utility model belongs to the field of tin-phosphor bronze strip production technology, specifically relating to tin-phosphor bronze strip production equipment, and particularly to annealing equipment and cold rolling system for high-resilience tin-phosphor bronze strip. Background Technology

[0002] Traditional bell-type annealing furnaces typically employ a "bell-shaped" structural design, consisting of a liftable upper cover (furnace cover) and a fixed base (furnace platform). Copper strip coils are horizontally stacked on the base, and the upper cover is precisely fastened to the sealing surface of the base using hoisting equipment to form a sealed annealing chamber. This equipment is widely used in the field of high-precision copper strip production, and has extremely high requirements for temperature uniformity, atmosphere control, and sealing during the annealing process.

[0003] During the loading operation, the upper cover (or lower cover) needs to be vertically lifted from its initial position to a preset height using a crane or lifting equipment so that operators can hoist the copper strip coil to the base or remove the finished strip coil from the base. Due to the large overall mass of the upper cover (or lower cover) (usually several tons or even tens of tons), uneven center of gravity distribution, and deviation between the hoisting point and the geometric center, lateral offset or longitudinal swaying is very likely to occur during the hoisting process. This unsteady motion not only increases the difficulty of operation and safety risks, but also directly causes periodic impact loads on the sealing contact surface between the upper cover and the base. When the offset exceeds the design tolerance range, rigid collisions or friction will occur in local areas of the sealing surface, causing irreversible damage such as peeling of the surface coating, decrease in flatness, or even micro-cracks. In severe cases, it may even be necessary to stop the machine for maintenance and replacement of the sealing components, which significantly reduces the equipment utilization rate and production efficiency.

[0004] Therefore, how to prevent the sealing contact surfaces of the upper cover and the base from wearing each other is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0006] This disclosure provides at least a high-resilience tin-phosphor bronze strip annealing equipment and a cold rolling system to solve the technical problem of mutual wear between the sealing contact surfaces of the upper cover and the base.

[0007] In a first aspect, embodiments of this disclosure provide an annealing apparatus and cold rolling system for high-resilience tin-phosphor bronze strip, comprising: a base and a cover adapted to the base, wherein ear blocks are provided on both sides of the cover and a guide ring is provided at the center of the ear blocks; a pair of guide rods symmetrically arranged on both sides of the base, and the cover moves up and down along the guide rods via the guide rings; a limiting seat fixed to the bottom of the guide rods, and a buffer element adapted to the guide rings is embedded inside the limiting seat; wherein the cover is adapted to move downward along the guide rods until the guide rings are inserted into the limiting seat and squeeze the buffer element, so that the cover falls on the mounting surface of the base.

[0008] In one optional embodiment, the top surface of the limiting seat is provided with an annular groove, and the top edge of both the inner wall and the outer wall of the annular groove is provided with a chamfered surface.

[0012] In one alternative embodiment, the cavity is filled with lubricating oil.

[0013] In one alternative embodiment, the inner wall of the mounting groove facing the center of the annular groove is provided with through holes.

[0014] In one optional embodiment, an oil drain hole is provided on the inner wall of the annular groove, which is connected to the through hole one by one; wherein, the guide ring squeezes the buffer to reduce the cavity volume, so that the lubricating oil is sprayed from the oil drain hole onto the inner wall of the guide ring, and moves along the guide rod through the guide ring to coat the lubricating oil.

[0015] In one alternative embodiment, the diameter of the oil drain hole gradually decreases along the direction away from the center of the annular groove.

[0028] Research has revealed that during the loading phase, the upper cover (or lower cover) needs to be vertically lifted from its initial position to a preset height using a crane or lifting equipment so that operators can hoist the copper strip coils to the base or remove the finished strip coils from the base. Due to the large overall mass of the upper cover (or lower cover) (usually several tons or even tens of tons), uneven center of gravity distribution, and deviation between the hoisting point and the geometric center, lateral offset or longitudinal swaying is very likely to occur during hoisting. This unsteady motion not only increases the difficulty of operation and safety risks, but also directly causes periodic impact loads on the sealing contact surface between the upper cover and the base. When the offset exceeds the design tolerance range, rigid collisions or friction will occur in local areas of the sealing surface, causing irreversible damage such as peeling of the surface coating, decreased flatness, or even micro-cracks. In severe cases, it may even be necessary to stop the machine for maintenance and replacement of the sealing components, significantly reducing equipment uptime and production efficiency.

[0029] Therefore, how to prevent the sealing contact surfaces of the upper cover and the base from wearing each other is a technical problem that urgently needs to be solved in this field.

[0030] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] like Figures 1 to 3 As shown, some embodiments provide annealing equipment and cold rolling system for high-resilience tin-phosphor bronze strip, including a base 1 and a cover 2 adapted to the base 1. The cover 2 has lugs 21 on both sides, and a guide ring 22 is provided at the center of the lugs 21. The upper and lower halves of the guide ring 22 extend to the outside of the lugs 21. In addition, the cover 2 is provided with a lifting hole and is connected to a lifting device. After the lifting device lifts the cover 2 to a certain height, it feeds the material onto the base 1, and then the lifting device lowers the cover 2 onto the mounting surface of the base 1.

[0034] To prevent the cover 2 from shifting during vertical movement, a pair of guide rods 3 are provided on both sides of the base 1. The guide rods 3 are symmetrically arranged on both sides of the base 1. The cover 2 moves up and down along the guide rods 3 via the guide ring 22. A limiting seat 4 is fixed to the bottom of the guide rods 3, and a buffer 5 adapted to the guide ring 22 is embedded inside it. The cover 2 is adapted to move downward along the guide rods 3 until the guide ring 22 is inserted into the limiting seat 4 and squeezes the buffer 5 so that the cover 2 lands on the mounting surface of the base 1. Before the cover 2 moves downward to the mounting surface of the base 1, the guide ring 22 first extends into the limiting seat 4 and abuts against the buffer 5 to generate a squeezing force. While limiting, it further achieves the buffering effect, which not only avoids the wear of the mounting surface caused by the overall shift of the cover 2, but also reduces the instantaneous force of the cover 2 landing on the mounting surface of the base 1 through the ring groove, further reducing wear during assembly.

[0035] The following describes the composition and structure of the limiting seat 4. The top surface of the limiting seat 4 is provided with an annular groove 41. The inner wall and the top edge of the outer wall of the annular groove 41 are provided with chamfered surfaces 42. The annular groove 41 is adapted to the guide ring 22. The chamfered surfaces 42 facilitate the guide ring 22 to move into the depth of the annular groove 41.

[0036] The buffer component 5 not only provides a buffering and pressure relief effect, but also replenishes the inner surface of the guide ring 22 with oil, preventing dry friction when it moves up and down along the guide rod 3. Specifically, the buffer component 5 includes a rubber ring 51, which has a cavity 52 inside. The cavity 52 is filled with lubricating oil.

[0037] In addition, there are clamping grooves 43 on both sides of the annular groove 41, and the buffer 5 is embedded in the clamping groove 43. The bottom surface of the annular groove 41 is provided with a deformation groove 44. The guide ring 22 is adapted to squeeze the buffer 5, so that part of it extends into the deformation groove 44. The rubber ring 51 is clamped in the clamping groove 43, and its bottom surface abuts against the bottom surface of the annular groove 41. When the rubber ring 51 is squeezed by the guide ring 22, the overall weight of the cover 2 will also be concentrated on the rubber ring 51, and part of the rubber ring 51 will bulge into the deformation groove 44. During this process, the volume of the cavity 52 will deform, and then some of the lubricating oil inside will be conveyed outward. The setting of the conveying channel is described in detail below. The inner wall of the clamping groove 43 facing the center position of the annular groove 41 is evenly distributed with through holes 46. An oil drain hole 45 is provided on the inner wall of the annular groove 41. An oil drain hole 45 (lubricating oil outlet) is provided on the inner wall side of the annular groove 41. A through hole 46 (lubricating oil inlet) is provided on the inner wall of the mounting groove 43 on the same side as the inner wall side of the annular groove 41. Under pressure, lubricating oil enters the channel through the through hole 46 and acts on the inner surface of the guide ring 22 through the oil drain hole 45. The oil drain hole 45 and the through hole 46 are connected one by one. The diameter of the oil drain hole 45 gradually decreases in the direction away from the center of the annular groove 41. The guide ring 22 squeezes the buffer member 5 to reduce the volume of the cavity 52, so that the lubricating oil is sprayed from the oil drain hole 45 onto the inner wall of the guide ring 22. The guide ring 22 moves along the guide rod 3 to coat the lubricating oil.

[0038] Some embodiments also provide a cold rolling system including: a plurality of annealing devices as described above, specifically, the cold rolling system includes multiple annealing devices for processing copper strip coils at different temperatures.

[0039] In summary, by setting the limiting seat 4 and the buffer 5, the buffering effect is further achieved while limiting the position. This not only avoids wear on the mounting surface caused by the overall offset of the offset cover 2, but also reduces the instantaneous force of the cover 2 falling on the mounting surface of the base 1 through the annular groove, further reducing wear during assembly. In addition, by filling the buffer 5 with lubricating oil, the buffering effect is further improved. Furthermore, the inner wall of the guide ring 22 can be lubricated to prevent dry friction when the guide ring 22 moves along the guide rod 3, effectively reducing operating noise.
