Description

Technical Field

[0001] This utility model belongs to the field of ingot casting technology, specifically relating to a stop device for preventing the slippage of round ingots. Background Technology

[0002] Titanium and titanium alloys have high specific strength, excellent corrosion resistance, good hot working properties and biocompatibility, and are widely used in aerospace and biomedical fields.

[0003] Currently, most titanium and titanium alloy ingots produced in industry are produced using vacuum arc remelting (VAR). Before ingot preparation, appropriate raw materials are usually selected according to composition standards, and the process involves proportioning calculation, weighing and mixing, electrode block pressing, arc remelting welding, vacuum arc remelting, and machining (such as sampling, peeling, and sawing risers) to complete the production and storage of the ingots.

[0004] Compared to traditional metals (such as copper, aluminum, and steel), titanium and titanium alloys have higher raw material costs, and the introduction of foreign materials must be strictly controlled during the ingot production process. Typically, after the ingot is removed from the furnace, the ingot number and grade are marked on the head end face. Then, a crane lifts the ingot and places it horizontally on an I-beam channel fixed to the ground. The upper surface of the I-beam channel is covered with stainless steel, which has a smooth surface and low friction with the ingot. Since the round titanium alloy ingot is not stable when placed horizontally on the I-beam channel, wooden blocks are usually used to support it and prevent it from sliding.

[0005] The tapping temperature of titanium and titanium alloy ingots is 300~400℃, and the weight of the ingots ranges from 40 to 8000 kg. Wooden blocks used to prevent the ingots from sliding may spontaneously combust at high temperatures or introduce other impurities that adhere to the outer surface of the ingots, thus introducing inclusions and affecting product quality. Furthermore, if the wooden blocks fall onto the channel steel, the titanium alloy ingots may slide to the ground and hit workers, posing a significant risk to their lives and potentially causing accidents. Utility Model Content

[0006] The purpose of this utility model is to provide a stop device for preventing the slippage of round ingots, which solves the problem in the prior art where wooden blocks spontaneously combust at high temperatures or other debris adheres to the outer surface of the ingot, resulting in inclusions that affect product quality.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] In a first aspect, this utility model provides a stop device for preventing the slippage of a circular ingot, comprising a first stop, a second stop, and a wedge-shaped baffle;

[0009] The first stop block has a first groove, and the second stop block has a second groove. The first groove and the second groove together form a T-shaped groove.

[0010] The top of the first and second blocks are provided with through holes. The stud passes through the through holes at the top of the first and second blocks. The first and second blocks slide through the stud to set the distance between the first and second blocks.

[0011] A wedge-shaped baffle is connected above the first and second blocks.

[0012] A further improvement of this invention is that both the first stop and the second stop are detachable.

[0013] A further improvement of this invention is that the outer contour shapes of the first block and the second block are similar to the outer contour shape of a human ear.

[0014] A further improvement of this invention is that the stud is fixed by a nut.

[0015] A further improvement of this utility model is that the nut is a stainless steel nut.

[0016] A further improvement of this invention is that the stud is a stainless steel stud.

[0017] A further improvement of this invention is that both the first stop and the second stop are pure titanium stops.

[0018] A further improvement of this invention is that the wedge-shaped baffle is a pure titanium baffle.

[0019] A further improvement of this utility model is that the diameter of the through hole opened at the top of the first stop and the second stop is 10mm±5mm.

[0020] A further improvement of this utility model is that the first stop block, the second stop block, and the wedge-shaped baffle are integrated into one unit.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0031] To further understand the present invention, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the embodiments are merely illustrative and not intended to limit the scope of the invention.

[0032] This invention proposes a stop device for preventing the slippage of round ingots, which includes a first stop, a second stop, and a wedge-shaped baffle. The first stop has a first groove, and the second stop has a second groove, which together form a T-shaped groove. Through holes are formed at the top of both the first and second stops, through which studs pass. The first and second stops slide via the studs, and the distance between them is set. Compared to existing technologies, this invention effectively solves the problems of spontaneous combustion of wood blocks at high temperatures or the introduction of other impurities adhering to the outer surface of the ingot, leading to inclusions that affect product quality.

[0033] Example 1:

[0034] This embodiment discloses a stop device for preventing the slippage of a circular ingot. The structural schematic diagram and three-view diagram of the stop device for preventing the slippage of a circular ingot are shown below. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution of this embodiment is described in detail below:

[0035] The stop device used in this embodiment to prevent the circular ingot from sliding includes a first stop 1, a second stop 2, and a wedge-shaped baffle 6.

[0036] The first stop block 1 has a first groove, and the second stop block 2 has a second groove. Together, the first and second grooves form a T-shaped groove 3. The T-shaped groove 3 has a width of 65mm, a height of 62mm, rounded corners of 5mm at both ends, and a thickness of 5mm. In this embodiment, the dimensions of the T-shaped groove 3 can be appropriately adjusted according to the actual dimensions of the I-beam channel steel to ensure a tight fit between the first stop block 1 and the second stop block 2 and the I-beam channel steel.

[0037] The top of the first stop 1 and the second stop 2 are provided with through holes (the diameter of the through holes at the top of the first stop 1 and the second stop 2 is 10mm±5mm). The stud 4 passes through the through holes at the top of the first stop 1 and the second stop 2. The first stop 1 and the second stop 2 slide through the stud 4 to set the distance between the first stop 1 and the second stop 2.

[0038] A wedge-shaped baffle 6 is connected above the first stop 1 and the second stop 2. The wedge-shaped baffle 6 has a height of 90mm, a width of 20mm, and a length of 70mm. The wedge-shaped baffle 6 can directly contact the hot-cast ingot, thereby effectively preventing the ingot from sliding.

[0039] In this embodiment, both the first stop 1 and the second stop 2 can be disassembled, which makes the maintenance process simpler and faster for maintenance personnel. Maintenance personnel can quickly locate the stop with problems, thereby shortening the maintenance time and improving work efficiency.

[0040] In this embodiment, both the first stop 1 and the second stop 2 are pure titanium stops. Pure titanium stops are not only highly corrosion resistant, but also easy to process and weld.

[0041] In this embodiment, the outer contours of the first block 1 and the second block 2 are similar to the outer contour of the human ear, which not only facilitates processing and installation, but also enhances the stability of the blocks.

[0042] Specifically, the total height of the outer side of the ear-shaped block is 170 mm, with the upper end being 70 mm high and 50 mm thick, and the lower end being a cuboid with a height of 110 mm, a bottom length of 45 mm, and a thickness of 50 mm.

[0043] In this embodiment, the stud 4 is fixed by the nut 5. The nut 5 is a stainless steel nut. The stud 4 is also a stainless steel stud. Stainless steel nuts not only possess high strength and rigidity, enabling them to withstand significant tightening forces, but also offer excellent anti-loosening properties. Stainless steel studs not only possess high strength, enabling them to withstand significant tensile and torsional forces, but also exhibit good corrosion resistance.

[0044] In this embodiment, the wedge-shaped baffle 6 is a pure titanium baffle. Pure titanium baffles are not only highly corrosion-resistant, but also easy to process and weld.

[0045] In this embodiment, the first stop 1, the second stop 2, and the wedge-shaped baffle 6 are integrated into one unit, which not only enhances the overall stability of the stop device used to prevent the circular ingot from sliding, but also reduces connection points and gaps, making maintenance more convenient and thus reducing maintenance costs.

[0046] The working principle of the stop device for preventing the slippage of round ingots according to this utility model is explained as follows:

[0047] First, remove the nuts and studs on both sides of the A and B ear-shaped stops (also called the first stop 1 and the second stop 2). Separate the stop device used to prevent the round ingot from sliding into two parts. According to the size and direction of the I-shaped channel steel, fit the first stop 1 and the second stop 2 tightly with the upper surface of the channel steel. The first stop 1 and the second stop 2 should be aligned with the straightness of the I-shaped channel steel. The stud 4 passes through the center of the first stop 1 and the second stop 2. Use the nuts to apply force to combine the A and B ear-shaped stops with the I-shaped channel steel into a whole. This ensures that the first stop 1 and the second stop 2 are in close contact with each other and will not slide arbitrarily. The height of the stop to prevent the ingot from sliding is 90mm, and the end of the stop that contacts the ingot has a 5mm rounded corner. This not only reduces the damage to the surface of the ingot, but also prevents ingots of different diameters from sliding on the I-shaped channel steel. During the ingot production process, if the positions of the first stop 1 and the second stop 2 need to be moved, the studs 4 and nuts 5 at both ends of the A and B ear-shaped stop blocks can be opened to easily separate the first stop 1 and the second stop 2 from the I-shaped channel steel. The operation is simple and quick, which can achieve non-slip and centralized and orderly placement of the ingots, which not only ensures product quality, but also reduces the risk of hot ingots falling and injuring people.

[0048] This utility model relates to a stop device for preventing the slippage of round ingots. It is primarily applicable to the fixed placement of round ingots from vacuum consumable arc melting of refractory non-ferrous metals such as titanium and titanium alloys. This device allows freshly melted titanium and titanium alloy ingots to be grouped according to different ingot numbers, thus preventing the round ingots from sliding on the channel steel. Using an anti-slip ingot stop device on the upper surface of the I-beam channel steel (this utility model for preventing the slippage of round ingots), ingots of different numbers and grades can be confined within a certain area, thereby preventing on-site safety accidents and facilitating the traceability of subsequent ingots, improving on-site production management. Furthermore, this device can be easily disassembled, allowing the stops (first stop 1 and second stop 2) to quickly separate from the I-beam channel steel. The operation is simple and effective, confining ingots of different weights and diameters within a certain range, thus avoiding the risk of fire caused by wooden blocks or other padding materials, and the risk of hot ingots sliding to the ground and injuring people.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
