Description

Technical Field

[0001] The utility model relates to the technical field of ingot processing equipment, and in particular to a upsetting cover plate, a spherical upsetting cover plate assembly and a flat upsetting cover plate assembly. Background Art

[0002] The existing upsetting cover plate is usually designed as a round cake shape with four pin holes. Pins are inserted into the pin holes for the overhead crane to lift the upsetting cover plate during forging. However, during upsetting, the ingot needs to be placed on the workbench of the hydraulic press first, and then the upsetting cover plate is placed on the ingot. This requires pulling the workbench out of the press body of the hydraulic press, and then the overhead crane cooperates to place the upsetting cover plate on the ingot, and then the workbench is reset. The process is complex and the efficiency is low. And when placing the upsetting cover plate, workers also need to visually check whether it is aligned by eyes. Visual inspection by human eyes will have a certain angular error, and repeated alignment will reduce the production efficiency. After upsetting, the workbench still needs to be pulled out of the press body, and then the overhead crane cooperates to lift the upsetting cover plate out. The auxiliary time in the whole upsetting process is relatively long, and the forging efficiency is low. Summary of the Utility Model

[0003] The utility model aims to solve the problem of low efficiency caused by using the existing upsetting cover plate during ingot upsetting.

[0004] To solve the above problems, the utility model provides an upsetting cover plate, which includes a cover plate body and a tong handle. The cross-sectional outer contour of the cover plate body perpendicular to its thickness direction is rectangular. The two end faces of the cover plate body in its thickness direction are respectively a first plate surface and a second plate surface. One end of the tong handle is connected to the cover plate body, and the end of the tong handle connected to the cover plate body is located between the first plate surface and the second plate surface.

[0005] The upsetting cover plate provided by the utility model has the following technical effects compared with the prior art, but is not limited to:

[0006] When the ingot needs to be upset, after the ingot is placed on the workbench of the hydraulic press in advance, instead of pulling the workbench outwards, the cover plate body can be placed on the ingot by operating the clamping tong handle, so as to carry out subsequent upsetting processing. After the upsetting processing is completed, it is not necessary to pull the workbench outwards, but the upsetting cover plate can be removed by operating the clamping tong handle. Compared with the overhead crane lifting the upsetting cover plate, the upsetting cover plate of the utility model can cooperate with the operating machine, improving the forging efficiency of the ingot. In addition, since the cross-sectional outer contour of the cover plate body is rectangular, it can quickly measure the side distance accurately with the two side columns of the hydraulic press and align it, quickly place the upsetting cover plate above the center position of the ingot, avoiding the problem of repeated alignment, further shortening the auxiliary time in the upsetting process, and having higher forging efficiency.

[0007] Further, the first plate surface is a plane, and / or, the second plate surface is recessed to form a spherical concave surface, and a blind hole is provided at the lowest point of the spherical concave surface.

[0008] Further, the radius of the spherical concave surface is 1700 mm, the diameter of the blind hole is 350 mm, and the depth of the blind hole is 80 mm.

[0009] Further, a first rounded corner is provided at the connection between the blind hole and the spherical concave surface, and the radius of the first rounded corner is 30 mm - 40 mm.

[0010] Further, the cross-sectional outer contour of the cover plate body perpendicular to its thickness direction is square. The cover plate body includes four plate side surfaces located between the first plate surface and the second plate surface, and one end of the clamp handle is connected to the center of one of the plate side surfaces.

[0011] Further, the ratio of the side length of the square to the thickness of the cover plate body is 3.50 - 4.00.

[0012] Further, the ratio of the length of the clamp handle to its diameter is 1.90 - 2.00.

[0013] Further, a second rounded corner is provided between adjacent two of the plate side surfaces, and the radius of the second rounded corner is 1240 mm - 1260 mm.

[0014] The present utility model further provides a spherical upsetting cover plate assembly, including the upsetting cover plate as described above and a lower upsetting leakage tray. The second plate surface of the upsetting cover plate is recessed to form a spherical concave surface, the spherical concave surface faces the lower upsetting leakage tray, and the axis of the lower upsetting leakage tray is collinear with the center of the spherical concave surface.

[0015] Since the technical improvement and technical effect of the spherical upsetting cover plate assembly are at least the same as those of the upsetting cover plate, the spherical upsetting cover plate assembly will not be described in detail herein.

[0016] The present utility model further provides a flat upsetting cover plate assembly, including the upsetting cover plate as described above. There are two upsetting cover plates, and the first plate surfaces of the two upsetting cover plates are arranged oppositely.

[0017] Since the technical improvement and technical effect of the flat upsetting cover plate assembly are at least the same as those of the upsetting cover plate, the flat upsetting cover plate assembly will not be described in detail herein. Description of the Drawings

[0030] See Figure 1-2 , a upsetting cover plate according to an embodiment of the present utility model includes a cover plate body 1 and a clamp handle 2. The outer contour of the cross-section (XY cross-section) of the cover plate body 1 perpendicular to its thickness direction is rectangular. The two end faces of the cover plate body 1 in its thickness direction are a first plate surface 11 and a second plate surface 12 respectively. One end of the clamp handle 2 is connected to the cover plate body 1, and the end of the clamp handle 2 connected to the cover plate body 1 is located between the first plate surface 11 and the second plate surface 12.

[0031] Among them, the outer contour of the cross-section refers to the shape of the outermost edge of the cross-section of the cover plate body 1.

[0032] In this embodiment, when upsetting the ingot, after placing the ingot on the workbench of the hydraulic press in advance, instead of pulling out the workbench outward, the cover plate body 1 can be placed on the ingot by operating the manipulator 4 to clamp the clamp handle 2 for subsequent upsetting processing. After the upsetting processing is completed, instead of pulling out the workbench outward, the upsetting cover plate can be removed by operating the manipulator 4 to clamp the clamp handle 2. Compared with the overhead crane for lifting the upsetting cover plate, the upsetting cover plate of the present utility model can be used in cooperation with the manipulator 4, improving the forging efficiency of the ingot.

[0033] In addition, since the outer contour of the cross-section of the cover plate body 1 is rectangular, it can quickly measure the side distance accurately with the two side columns of the hydraulic press and quickly place the upsetting cover plate above the center position of the ingot, avoiding the problem of repeated alignment, further shortening the auxiliary time during the upsetting process and having higher forging efficiency.

[0034] See Figure 2 , optionally, the first plate surface 11 is a flat surface, and / or, a spherical concave surface 13 is formed by recessing the second plate surface 12, and a blind hole 14 is provided at the lowest point of the spherical concave surface 13.

[0035] In this embodiment, the two end faces of the cover plate body 1 in its thickness direction are respectively the first plate surface 11 and the second plate surface 12, where the first plate surface 11 is also the upper end face of the cover plate body 1, and the second plate surface 12 is also the lower end face of the cover plate body 1. Among them, the first plate surface 11 is a flat surface. Thus, when it is necessary to perform flat upsetting on the ingot, the manipulator 4 can be used to hold the tongs 2, so that the first plate surface 11 of the cover plate body 1 faces the ingot below, and then flat upsetting can be performed on the ingot through the first plate surface 11.

[0036] In this embodiment, a spherical concave surface 13 can be formed by recessing the second plate surface 12. Thus, when it is necessary to perform spherical upsetting on the ingot below, the manipulator 4 can be used to hold the tongs 2, so that the second plate surface 12 of the cover plate body 1 faces the ingot below, and then flat upsetting can be performed on the ingot through the spherical concave surface 13.

[0037] In the prior art, during spherical upsetting, after some ingots are processed by methods such as metallurgy or casting, there may be defects on the surface of their materials, that is, there are deposition piles at the bottom of the ingot. During spherical upsetting, the deposition piles at the bottom of the ingot move towards the ingot body due to the extrusion deformation of the body, which will cause the deposition piles to remain in the finished product.

[0038] Based on the above problems, in this embodiment, a blind hole 14 is provided at the lowest point of the spherical concave surface 13. Among them, as Figure 2 shown, the lowest point of the spherical concave surface 13 refers to the position on the Z-axis of the spherical concave surface 13 that is closest to the first plate surface 11. Thus, when it is necessary to perform spherical upsetting on the ingot, as Figure 3 shown, this upsetting cover plate can be used in combination with the lower upsetting leakage plate 3. First, place the lower upsetting leakage plate 3 on the workbench of the hydraulic press, and then place the deposition pile at the bottom of the ingot in the lower upsetting leakage plate 3 until the ingot abuts against the lower upsetting leakage plate 3 vertically; then use the manipulator 4 to hold the tongs 2 to place the cover plate body 1 on the ingot and align the cover plate body 1 with the ingot; then spherical upsetting can be performed on the ingot. As Figure 4 shown, due to the design of the blind hole 14, it provides a drainage and guiding space for the upward deformation and movement of the deposition pile at the bottom of the ingot body. Therefore, when the ingot is subjected to spherical upsetting, the part of the ingot containing the deposition pile will move upward and deform and enter the blind hole 14, and thus the residue of the deposition pile in the finished product can be significantly reduced.

[0039] When performing flat upsetting, two upsetting cover plates can be used in combination, as Figure 5As shown, a upsetting cover plate can be placed on the operating table of the hydraulic press by the manipulator 4 first, and the first plate surface 11 of the upsetting cover plate is arranged upward; then the ingot is placed on the lower upsetting cover plate; then another upsetting cover plate is placed on the ingot by the manipulator 4, and the first plate surface 11 of this upsetting cover plate is arranged downward, that is, the first plate surfaces 11 of the two upsetting cover plates are arranged oppositely; finally, the ingot can be upset flat through the upper upsetting cover plate, as Figure 6 shown. When upsetting flat between the two upsetting cover plates, it is not necessary to hoist the lower platform (the lower upsetting cover plate) and the upper upsetting cover plate by the overhead crane. The manipulator 4 directly clamps the handle 2 of the upsetting cover plate and easily places the upsetting cover plate in the required position, saving a lot of time and improving production efficiency.

[0040] Optionally, the radius of the spherical concave surface 13 is 1700 mm, the diameter of the blind hole 14 is 350 mm, and the depth of the blind hole 14 is 80 mm.

[0041] In this embodiment, the radius of the spherical concave surface 13 can be determined according to the products that can be upset by the 4500T at present and that do not affect the reciprocating movement of the manipulator 4 on the workbench. The radius of the spherical concave surface 13 can be 1700 mm, while the diameter of the blind hole 14 is 350 mm and the depth is 80 mm. For the blind hole 14 with such dimensions, on the one hand, it is convenient for machining, and on the other hand, it can meet the requirements during the spherical upsetting of most ingots.

[0042] See Figure 2 , optionally, a first rounded corner 16 is arranged at the connection between the blind hole 14 and the spherical concave surface 13, and the radius of the first rounded corner 16 is 30 mm - 40 mm.

[0043] In this embodiment, the outer end edge of the blind hole 14 and the spherical concave surface 13 are smoothly transitioned, specifically, a first rounded corner 16 is arranged. The first rounded corner 16 ensures that when the ingot is upset, the ingot can smoothly enter the blind hole 14 to reduce the residue of the deposition pile in the finished product. Among them, the radius of the first rounded corner 16 ranges between 30 mm and 40 mm, and it does not cause a large impact on the dimensions of the spherical concave surface 13 and the blind hole 14. For example, the radius of the first rounded corner 16 is 30 mm, 35 mm, 40 mm, etc., and 35 mm is preferred.

[0044] See Figure 1-2 , optionally, the cross-sectional outer contour of the cover plate body 1 perpendicular to its thickness direction is square. The cover plate body 1 includes four plate side surfaces 15 between the first plate surface 11 and the second plate surface 12, and one end of the handle 2 is connected to the center of one of the plate side surfaces 15.

[0045] In this embodiment, the cross-sectional outer contour of the cover plate body 1 is specifically a square. In this way, after determining the size of the spherical concave surface 13, the size and weight of the cover plate body 1 can be reduced as much as possible. One end of the pliers handle 2 is fixed at the center of a side plate. In this way, the entire upset cover plate is a symmetric structure, and the symmetry plane is a vertical plane coplanar with the axis of the pliers handle 2. On this basis, first, the upset cover plate can be uniformly stressed. Second, after the manipulator 4 clamps the pliers handle 2, through the flipping action, the first plate surface 11 and the second plate surface 12 can be swapped, and after the swapping, the upset cover plate does not need to be aligned again.

[0046] Optionally, the ratio of the side length of the square to the thickness of the cover plate body 1 is 3.50 - 4.00.

[0047] In this embodiment, the size of the cover plate body 1 can be determined according to the products that can be upset by 4500T currently and that do not affect the back-and-forth movement of the manipulator 4 on the workbench. Among them, the ratio range of the side length of the square to the thickness of the cover plate body 1 is between 3.50 and 4.00, so that there is enough space on the second plate surface 12 of the cover plate body 1 to open the spherical concave surface 13 to ensure that the spherical concave surface 13 and the blind hole 14 can meet the design depth requirements, and at the same time ensure that the structural strength of the cover plate body 1 itself is sufficient. For example, the side length of the square can be 1750mm, 2000mm or 2200mm, and the thickness of the cover plate body 1 can be the corresponding 500mm, 530mm or 550mm. Among them, it is preferred that the side length of the square is 2000mm and the thickness of the cover plate body 1 is 530mm, and the corresponding ratio is 3.77.

[0048] Optionally, the ratio of the length to the diameter of the pliers handle 2 is 1.90 - 2.00.

[0049] In this embodiment, the length of the pliers handle 2 can be 665mm, 700mm or 740mm, and the diameter can be the corresponding 350mm, 360mm or 370mm. Among them, the preferred length of the pliers handle 2 is 700mm, and the preferred diameter is 360mm, so the ratio is preferably 1.94 to ensure that the pliers handle 2 has a certain length for the manipulator 4 to clamp, and the diameter of the pliers handle 2 is 360mm to ensure that the pliers handle 2 has a certain thickness to prevent the connection between the pliers handle 2 and the cover plate body 1 from breaking.

[0050] See Figure 1 , optionally, a second fillet 17 is provided between two adjacent side plates 15, and the radius of the second fillet 17 is 1240mm - 1260mm. The radius of the second fillet 17 can be 1240mm, 1250mm or 1260mm, and is preferably 1250mm.

[0051] In this embodiment, a second chamfered corner 17 is provided between adjacent plate sides 15 to prevent the edges of the cover plate body 1 from being knocked and to prevent the cover plate body 1 from accidentally injuring the staff. Among them, when the side length of the square is 2000 mm, the radius of the second chamfered corner 17 can be 1250 mm to ensure that the setting of the second chamfered corner 17 does not encroach on the opening area of the spherical concave surface 13 and is also convenient for its own processing and forming.

[0052] It should be noted that in addition to being able to perform flat upsetting and spherical upsetting, the upsetting cover plate also has other functions. Specifically, the plate side 15 can be used as a narrow anvil for spreading forging. When performing spreading forging, the upsetting cover plate is erected and clamped by the manipulator 4. At this time, the upsetting cover plate is equivalent to a narrow anvil, and the upper anvil of the hydraulic press cooperates with the rotary table for spinning, which can be used for spreading and the edge opening of the head plate blank.

[0053] To sum up, the upsetting cover plate of the present utility model has a simple shape, is easy to manufacture and produce, is convenient to place, can improve production efficiency, reduce production costs, and has multiple functions. It can not only save the placement space of auxiliary tools, but also greatly save a sum of auxiliary tool expenses.

[0054] Another embodiment of the present utility model provides a spherical upsetting cover plate assembly, including the upsetting cover plate as described above and a lower upsetting leak tray 3. A spherical concave surface 13 is formed by the depression of the second plate surface 12 of the upsetting cover plate. The spherical concave surface 13 faces the lower upsetting leak tray 3, and the axis of the lower upsetting leak tray 3 is collinear with the center of the spherical concave surface 13.

[0055] Since the technical improvement and technical effect of the spherical upsetting cover plate assembly are at least the same as those of the upsetting cover plate, the spherical upsetting cover plate assembly will not be described in detail herein.

[0056] Another embodiment of the present utility model provides a flat upsetting cover plate assembly, including the upsetting cover plate as described above. There are two upsetting cover plates, and the first plate surfaces of the two upsetting cover plates are arranged opposite to each other.

[0057] Since the technical improvement and technical effect of the flat upsetting cover plate assembly are at least the same as those of the upsetting cover plate, the flat upsetting cover plate assembly will not be described in detail herein.

[0058] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0059] Although the present utility model is disclosed as above, the protection scope of the present utility model disclosed is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model disclosed, and these changes and modifications will all fall within the protection scope of the present utility model.
