Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of rolling technology for large titanium alloy rings, specifically a tooling for pre-rolling transfer and heat preservation of large titanium alloy rings. Background Technology
[0002] Titanium alloys have unique material properties, including a narrow rolling deformation temperature range and sensitivity to temperature changes, making them prone to cracking. Traditional rolling processes address temperature drop issues through rapid transfer methods, such as robotic arms, rapid loading / unloading machines, and dedicated high-speed cranes. However, the cranes and hoists used in large-scale ring rolling production lines are too slow to meet the required transfer time for titanium alloy rolling.
[0003] To address the temperature drop issue before titanium alloy rolling, the traditional approach is to maximize the ring transfer speed and shorten the time from the furnace to the rolling mill platform. However, increasing the speed using large overhead cranes and large lifting devices requires considerable cost and yields minimal results. Furthermore, using loading and unloading machines has maximum size and weight limitations, making it impossible to handle the loading and unloading of large and extra-large rings. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a tooling for pre-rolling transfer and heat preservation of large titanium alloy rings. This solution takes a different approach, namely, adding heat preservation measures during the transfer process. It can meet the rolling temperature requirements of large non-ferrous metal rings without requiring large investments or modifications to existing equipment, effectively reducing the temperature drop of the rings before rolling and improving the success rate of rolling.
[0005] To achieve the above objectives, this utility model employs the following technical solution:
[0006] A fixture for pre-rolling transfer and insulation of large titanium alloy rings includes a top body, a sliding top plate, a dimension extension top plate, and insulation side plates. The sliding top plate is slidably installed in the top body and can slide outward and retract to both sides of the top body. The dimension extension top plate is movably installed on both sides of the top body. The insulation side plates are fixed to the bottom outer sides of the sliding top plate and the dimension extension top plate. The top body includes two guide beams, and two lifting beams are fixedly connected to the two guide beams. An insulation plate is fixedly arranged at the lower part of the guide beams, and lifting points are provided on the lifting beams.
[0007] A slide rail is fixedly installed on one side of the two guide beams that are close to each other. The slide rail has two layers, and two connecting bottom beams are fixedly connected between the two guide beams.
[0008] The sliding top plate includes a frame, and the frame is provided with a second heat insulation board.
[0009] The size expansion top plate includes expansion module one, expansion module two, and expansion module three. Expansion module one and expansion module two are respectively fixedly connected to one side of expansion module three, and several expansion modules three are inserted and installed together.
[0010] The insulation side panel includes a perforated steel plate frame, and an insulation plate is provided inside the perforated steel plate frame.
[0011] Compared with the existing technology, the beneficial effects of this utility model are:
[0012] This invention can keep the billet warm during the transfer process through the design of the heat-insulating tooling structure, and immediately keep the ring warm and isolated after it comes out of the furnace. It can keep the ring warm from the time it comes out of the furnace until the start of rolling without making a large investment or modification to the existing equipment. It can meet the rolling temperature requirements of large non-ferrous metal rings, effectively reduce the temperature drop of the ring before rolling, and improve the success rate of rolling.

[0024] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0025] Combined with appendix Figures 1-10 A tooling for pre-rolling transfer and heat preservation of large titanium alloy rings includes a top body 1, a sliding top plate 2, a size extension top plate 3, and heat preservation side plates 4. The sliding top plate 2 is slidably installed in the top body 1 and can slide outward and retract to both sides of the top body 1. The size extension top plate 3 is movably installed on both sides of the top body 1. The heat preservation side plates 4 are fixed to the bottom outer sides of the sliding top plate 2 and the size extension top plate 3. The top body 1 includes two guide beams 11, and two lifting beams 12 are fixedly connected to the two guide beams 11. A heat preservation plate 13 is fixedly arranged at the lower part of the guide beams 11, and the lifting beams 12 are provided with lifting points 120. Two lifting beams 12 are arranged in parallel and perpendicular to the guide beam 11. The lifting beams 12 are welded and fixed to the guide beam 11 by reinforcing ribs. Two lifting points 120 are provided on both sides of each lifting beam 12. The lifting beams 12 are perforated to reduce weight. The outer frame of the insulation board 13 is welded to the bottom of the guide beam 11 by angle steel. The guide beam 11 is longer than the insulation board 13. The gap between the two guide beams 11 on both sides is used to limit the relative position of the lifting arm and ensure that the lifting device will not shake when it is clamped. The insulation board 13 serves as heat insulation.
[0026] A slide rail 110 is fixedly installed on one side of the two guide beams 11 that are close to each other. The slide rail 110 has two layers, and two connecting bottom beams 111 are fixedly connected between the two guide beams 11. Two sliding top plates 2 that slide to both sides are slidably installed in the two layers of slide rails 110. The two layers of slide rails 110 are staggered, so that the two sliding top plates 2 overlap and do not interfere with each other during movement. The connecting bottom beams 111 serve to reinforce the top body 1 and improve the overall structural strength of the top body 1.
[0027] The sliding top plate 2 includes a frame 20, and an insulation plate 21 is provided in the frame 20. The edge of the frame 20 located inside the top body 1 and the outer edge of the slide rail 110 can be fixedly provided with pulleys to reduce the resistance when the sliding top plate 2 slides in the slide rail 110. At the same time, the fixed pulleys can play a limiting role to prevent the sliding top plate 2 from falling off the slide rail 110. The pulleys are made of high temperature resistant metal wheels.
[0028] The size-expanding top plate 3 includes expansion module one 31, expansion module two 32, and expansion module three 33. Expansion module one 31 and expansion module two 32 are respectively fixedly connected to one side of expansion module three 33, and several expansion modules three 33 are inserted and installed together. The size-expanding top plate 3 is also made of a welded metal frame with an internal insulation board, and the insulation board is an aluminum silicate insulation board. In use, the appropriate expansion module can be selected according to the blank size to adjust the size of the insulation cover to accommodate more product specifications.
[0029] The insulation side panel 4 includes a perforated steel plate frame 40, within which an insulation board 41 is installed. The insulation side panel 4 is formed by bending a perforated steel plate to create a frame, with an aluminum silicate insulation board inserted inside. The steel plate frame improves the overall strength of the insulation board, the perforations reduce weight, and provide perforations for fixing the insulation board. The width and height of the insulation side panel 4 can be modified according to the product dimensions. During installation, it is suspended by chains or welded to the main body of the extended top plate 3.
[0030] Assembly of the insulation cover:
[0031] ①For example Figure 6 As shown, the top main body is now suspended from the bottom of the ring lifting device using four hand-operated hoists. The overall height and level of the insulation cover are adjusted using the hand-operated hoists according to the height of the rolled titanium alloy product. To ensure insulation performance, a clearance of 150-200mm is typically left between the upper surface of the ring and the insulation cover.
[0032] ②For example Figure 7 As shown, insert the two sliding top plates into the top body and confirm that the pushing and pulling is smooth. Select a suitable insulation cover size expansion module according to the outer diameter of the ring blank, and assemble it so that the insulation cover is slightly larger than the outer diameter of the blank to improve the insulation effect.
[0033] ③ Select an appropriate height for the insulation side panel based on the height of the ring blank, and install the insulation side panel onto the outside of the frame from step 2. Ensure they are tightly connected to reduce heat leakage at the joints.
[0034] Usage process:
[0035] ①For example Figure 8 As shown, assemble the insulation cover that matches the size of the blank and assemble it with the lifting device. Pull out the movable top plate, open the lifting device clamps to the appropriate position, and the crane carries the lifting device to the position above the blank exiting the furnace and stops to wait.
[0036] ②For example Figure 9 As shown, after the ring blank is heated to the specified temperature, the trolley is removed from the furnace and stops in its designated position. The lifting device immediately descends to the clamping position, the clamping legs grip it, and at the same time, the movable top plate is pushed to make the insulation side plate of the movable top plate fit tightly against the outer wall of the ring. Once the clamping legs are in place, the insulation cover has also completed its sealing and insulation work.
[0037] ③ For example Figure 10 As shown, once the lifting device is securely clamped, it can be raised to transfer the titanium alloy billet to the ring mill rolling platform. After the billet settles, the lifting device's clamp legs are opened. The movable top plate does not open with the clamp legs, continuing the insulation process. Once the clamp legs are fully open, the lifting device is raised, lifting the insulation cover away from the titanium alloy billet. The entire insulation process is complete, and the ring rolling operation begins.
[0038] The method for manufacturing and using the heat insulation cover described in this patent can meet the rolling temperature requirements of large non-ferrous metal rings without requiring major investment or modification of existing equipment.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
