Description

Technical Field

[0001] This utility model relates to the field of ring forging forming, and more specifically, to a mold for partial loading forming of an irregular cross-section ring forging. Background Technology

[0002] The irregular cross-section ring forging local loading forming die is a type of die used in the forging field. Irregular cross-section ring forgings are gradually formed by die limiting and local loading. The core is to use the cooperation of different die components to forge simple blanks into ring parts with complex irregular cross-sections.

[0003] After forging, the ring forging will undergo lateral deformation. Sometimes, the middle position of the ring forging will get stuck on the outer wall of the limiting punch, making it difficult to demold the ring forging and affecting work efficiency. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a local loading forming mold for irregular cross-section ring forgings. This mold can achieve the cooling and shrinking of the limiting punch by allowing liquid water to pass through the first and second water channels, and the downward movement of the pusher plate driven by the vertical block through the transfer block, so that the workpiece after forging is separated from the limiting punch and demolded.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A partial loading forming mold for an irregular cross-section ring forging includes a forging assembly and a base. An outer ring mold is installed at both output ends of the base, and an inner ring mold is installed on the inner wall of the outer ring mold. The upper middle part of the base is used to prevent the forging part from being forged, and a demolding device is installed at the lower end of the forging assembly. The forging assembly includes a pressure rod, a limiting plate is installed at the lower end of the pressure rod, and a through hole is provided in the middle of the limiting plate; The demolding device includes a forging plate with a fixed frame mounted on its upper end. A through hole is formed in the center of the forging plate, and a sliding hole is formed below the through hole in the center of the forging plate. A limiting punch is mounted in the center of the fixed frame, and a first and second water channel are connected in the center of the limiting punch. A transfer block is slidably connected to the outside of the limiting punch in the center of the through hole. A pusher plate is mounted at the lower end of the transfer block, and a vertical block is mounted at the outer end of the transfer block. The sliding hole matches the pusher plate, and the vertical block corresponds to the through hole. Liquid water flows through the first and second water channels, causing the limiting punch to cool and shrink. The vertical block, driven by the transfer block, moves the pusher plate downwards, causing the forged workpiece to separate from the limiting punch and be demolded.

[0007] Furthermore, the fixing frame is fixedly installed with the limiting plate, and the upper end of the vertical block is wedge-shaped, so that the fixing frame can drive the limiting plate to move, and the upper end of the vertical block is not easily deformed when subjected to impact.

[0008] Furthermore, the forging assembly can introduce liquid water into the first water channel, and the forging assembly can extract the liquid water inside the first water channel through the second water channel, so that the liquid water can pass through the first water channel and the second water channel to cool down the limiting punch.

[0009] Furthermore, the base, inner annular mold, forging plate, pusher plate, and limiting punch can form the required forging shape of the workpiece, so that the workpiece can be forged and formed.

[0010] Furthermore, the limiting plate can cover the upper end of the outer annular mold, and the inner annular mold can be replaced, so that the slag block is not easily splashed outward from the middle of the outer annular mold during the forging process, and the inner annular mold can be flexibly replaced according to the required forging shape.

[0011] Compared with existing technologies, the advantages of this utility model are: (1) In this scheme, liquid water passes through the first water channel and the second water channel to cool and shrink the limiting punch, and the vertical block drives the pusher plate to move downward through the transfer block, so that the workpiece after forging is separated from the limiting punch and demolded.

[0012] (2) The worker can strike the upper end of the vertical block with a hammer to apply a downward force to the vertical block, thereby causing the limiting punch to be demolded from the workpiece after forging. Attached Figure Description

[0018] Example 1 This embodiment illustrates the structure of the device and its beneficial effects: Please see Figure 1-6 A partial loading forming mold for an irregular cross-section ring forging includes a forging assembly 1 and a base 3. Both output ends of the base 3 are equipped with an outer ring mold 4, and an inner ring mold 5 is installed on the inner wall of the outer ring mold 4. The upper middle part of the base 3 is protected with a forging part 6, and a demolding device 2 is installed at the lower end of the forging assembly 1. The forging assembly 1 includes a pressure rod 101, a limiting plate 102 is installed at the lower end of the pressure rod 101, and a through hole 103 is provided in the middle of the limiting plate 102; The demolding device 2 includes a forging plate 201, a fixed frame 202 installed on the upper end of the forging plate 201, a through hole 203 in the middle of the forging plate 201, a sliding hole 204 in the middle of the forging plate 201 located below the through hole 203, a limiting punch 205 installed in the middle of the fixed frame 202, a first channel 206 and a second channel 207 in the middle of the limiting punch 205, the first channel 206 and the second channel 207 being connected, a transfer block 208 slidably connected to the outside of the limiting punch 205 located in the middle of the through hole 203, a pusher plate 209 installed at the lower end of the transfer block 208, a vertical block 210 installed at the outer end of the transfer block 208, the sliding hole 204 matching the pusher plate 209, and the vertical block 210 corresponding to the through hole 103.

[0019] Please see Figure 3-5 The fixing frame 202 is fixedly installed with the limiting plate 102, and the upper end of the vertical block 210 is wedge-shaped, which allows the fixing frame 202 to drive the limiting plate 102 to move, and the upper end of the vertical block 210 is not easily deformed when subjected to impact. The forging assembly 1 can introduce liquid water into the first water channel 206, and the forging assembly 1 can extract the liquid water inside the first water channel 206 through the second water channel 207, so that the liquid water can pass through the first water channel 206 and the second water channel 207 to cool the limiting punch 205.

[0020] Please see Figure 1 The base 3, inner annular mold 5, forging plate 201, pusher plate 209, and limiting punch 205 can form the required forging shape of the workpiece 6 to be forged, so that the workpiece 6 can be forged and formed. The limiting plate 102 can cover the upper end of the outer annular mold 4, and the inner annular mold 5 can be replaced, so that the slag block of the workpiece 6 is not easily splashed outward from the middle of the outer annular mold 4 during the forging process, and the inner annular mold 5 can be flexibly replaced according to the required forging shape.

[0021] Example 2 This embodiment illustrates the working principle of the device: During forging, the workpiece 6 to be forged is installed on the upper side of the base 3. The output end of the base 3 drives the outer annular mold 4 and the inner annular mold 5 to move to the outside of the workpiece 6 to form an annular mold of the shape to be forged. Then, the forging assembly 1 drives the demolding device 2 to move downward and the forging plate 201 to move downward. When the pusher plate 209 contacts the upper surface of the workpiece 6 to be forged, the workpiece 6 pushes the pusher plate 209 into the middle of the sliding hole 204. Then, the forging plate 201 continues to move downward. The forging plate 201 and the pusher plate 209 perform forging operations on the workpiece 6 to be forged. The workpiece 6 to be forged fits against the inner wall of the inner annular mold 5, completing the irregular forging work of the workpiece 6 to be forged. Afterwards, the output end of the base 3 drives the outer annular mold 4 and the inner annular mold 5 to separate from the workpiece 6 to be forged. The forging assembly 1 drives the demolding device 2 to move upward. If the workpiece 6 to be forged is not separated from the limiting punch 205 after forging, liquid water is passed through the first water channel 206 and the second water channel 207 through the forging assembly 1, so that the liquid water cools down the limiting punch 205. The limiting punch 205 shrinks after cooling down. At the same time, the worker strikes the upper end of the vertical block 210 with a hammer, so that the vertical block 210 drives the pusher plate 209 to move downward through the transfer block 208. The pusher plate 209 pushes the workpiece 6 to be forged after forging to complete the demolding operation with the limiting punch 205. Liquid water passes through the first water channel 206 and the second water channel 207, causing the limiting punch 205 to cool and shrink. The vertical block 210 drives the pusher plate 209 to move downward through the transfer block 208, so that the workpiece after forging is separated from the limiting punch 205 and demolded.

[0022] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
