Description

Technical Field

[0001] This utility model relates to the field of forging processing, and in particular to a general-purpose V-shaped anvil. Background Technology

[0002] V-shaped anvils are one of the important tooling tools used for elongating forgings in forging processing. Existing V-shaped anvils mainly consist of an upper anvil and a lower anvil. The lower anvil has a V-shaped opening for placing the forging, while the upper anvil can be a flat anvil with a flat bottom or a concave V-shaped groove. However, in existing V-shaped anvils, the upper and lower anvils are independent units. If the upper or lower anvil is damaged, the entire upper or lower anvil needs to be replaced separately, increasing the practical cost. Moreover, the current V-shaped anvil has a single function, which can only be used for elongating forgings. Of course, in actual forging processing, some operators also use the V-shaped groove on the V-shaped anvil to place the forging billet that needs to be separated into the V-shaped groove of the V-shaped anvil and separate it with a separating knife.

[0003] The current material separation method involves one operator using a manipulator to clamp the forging billet and place it on a V-shaped anvil or a lower flat anvil, while another operator holds a material separation knife and places it on the forging billet. The press is then started to press down, and the upper flat anvil installed at the bottom of the press presses the material separation knife to draw a mark on the billet. Then, the operator uses the manipulator to clamp and rotate the forging billet, while the other operator holds the material separation knife, aligns it with the previous mark, and starts the press down again to press out a second mark through the upper flat anvil. This process is repeated until a circle of marks is pressed out on the forging billet, thus separating the material.

[0004] The drawbacks of this material separation method are as follows: at least one operator is required to hold the material separation knife and visually align the forging blanks before cooperating with the press to separate them. This results in low work efficiency, and the alignment accuracy of the material separation marks is often not high, affecting the surface quality of the subsequent forgings. Furthermore, the machining allowance needs to be designed to be relatively large. In addition, the material separation knife needs to be held by the worker, so the weight of the material separation knife must be considered and it cannot be designed to be too large or too heavy. The worker needs to be close to the forging blank to operate, and the forging blank to be separated is usually heated to a high temperature of over 1000 degrees Celsius. The operator's manual approach to the material separation is labor-intensive, and the ambient temperature is very high, resulting in low safety and very low efficiency. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a universal V-shaped anvil that can be used to facilitate the drawing of forgings and to facilitate the cutting of forging blanks.

The top of the V-shaped insert is provided with a V-shaped groove, and the bottom of the V-shaped groove has an arc-shaped structure.

[0009] Furthermore, the V-groove is provided with a cutting edge that conforms to its contour shape. The cross-section of the cutting edge is triangular, and it is integrated with the V-shaped insert to form a material separating blade insert.

[0010] Furthermore, the top two sides of the V-shaped groove have symmetrical fixing grooves, and the bottom of the fixing groove is provided with a threaded connection hole; the top two ends of the V-shaped insert are provided with mutually symmetrical flange joints, the flange joints are embedded in the fixing grooves, and the top of the flange joints is provided with a fixing hole that is vertically connected. The fixing hole and the threaded connection hole correspond vertically and are connected together by screws.

[0011] Furthermore, the bottom center of the V-shaped groove is provided with a top hole that extends downward through the bottom of the V-shaped anvil.

[0012] Furthermore, the upper anvil seat has an upper slot at its bottom and an upper block at its top, the upper block being horizontally engaged with the upper slot; the lower anvil seat has a lower slot at its top and a lower block at its bottom, the lower block being horizontally engaged with the lower slot.

[0013] Furthermore, both the upper and lower card slots are dovetail grooves; the bottom width of the upper card slot is greater than the top width of the upper card block; the top width of the lower card slot is greater than the bottom width of the lower card block.

[0014] Furthermore, the upper anvil base has an upper center groove at the bottom of the upper slot on both sides, and an upper center block at the top of the upper flat anvil base on both sides of the upper block. The upper center blocks and the upper center grooves are fitted together vertically. The lower anvil base has a lower center groove at the top of the lower slot on both sides, and a lower center block at the bottom of the V-shaped anvil base on both sides of the lower block. The lower center blocks and the lower center grooves are fitted together vertically.

[0015] Compared with the prior art, the advantages of this utility model are: this universal V-shaped anvil has a simple structure, and the upper and lower anvils are designed to be detachable, which facilitates the replacement of components and the local replacement after component damage, thus saving usage costs; V-shaped inserts or dividing blade inserts can be assembled on the V-shaped anvil according to processing needs.

[0030] Example

[0031] Please refer to the instruction manual attached. Figures 1 to 3 As shown, the instruction manual is attached. Figures 1 to 3 The illustration shows a specific embodiment of a general-purpose V-shaped anvil of this utility model, mainly used for drawing forgings and separating forging billets, which can improve its versatility and separation accuracy. Specifically, the general-purpose V-shaped anvil includes an upper anvil 1 and a lower anvil 2, which are correspondingly mounted on the lower platen of the press by bolts. The upper anvil 1 is mounted on the upper platen of the press by bolts. See the appendix of the specification. Figure 4As shown, the upper anvil 1 consists of a detachable upper anvil seat 11 and an upper flat anvil 12. The upper anvil seat 11 is fixed to the bottom of the upper template of the press by bolts, and the upper flat anvil 12 is disposed at the bottom of the upper anvil seat 11. The upper flat anvil 12 is inserted into the bottom of the upper anvil seat 11. Specifically, the bottom of the upper anvil seat 11 is provided with an upper retaining groove 111, which is arranged laterally along the left and right length direction of the upper anvil seat 11. The upper retaining groove 111 is a dovetail groove that passes through the front and rear ends of the upper anvil seat 11. The top of the upper flat anvil 12 is provided with an upper retaining block 121. The upper locking block 121 is a dovetail block that inserts into either end of the upper locking groove 111. The upper locking block 121 and the upper flat anvil 12 are integrally formed, and the upper locking block 121 and the upper locking groove 111 are inserted into each other horizontally. To ensure the accuracy of the assembly position of the upper flat anvil 12 on the upper anvil base 11, an upper centering groove 112 is provided at the bottom of the upper anvil base 11 on the left and right sides of the upper locking groove 111. The upper centering groove 112 extends through the left and right sides of the upper anvil base 11. Correspondingly, the top of the upper flat anvil 12 is located on the left and right sides of the upper locking block 121. The upper anvil 11 and the upper flat anvil 12 are provided with an upper centering block 122, which corresponds vertically to the upper centering groove 112. The upper centering block 122 and the upper centering groove 112 are interlocked vertically. The front and rear end faces of the combined upper anvil 11 and upper flat anvil 12 are flush vertically. To avoid the upper locking groove 111 and the upper locking block 121 from colliding and interfering when the upper anvil 11 and upper flat anvil 12 are assembled vertically, the bottom width of the upper locking groove 111 is greater than the top width of the upper locking block 121. When the upper flat anvil 12 is assembled on the upper anvil 11, the upper centering groove 112 and the upper... The centering block 122 is installed vertically, and the upper locking block 121 is inserted into the upper locking groove 111. After the upper anvil 11 and the upper flat anvil 12 are assembled vertically, the upper flat anvil 12 is moved horizontally to the left or right, so that one end of the upper locking block 121 on the top of the upper flat anvil 12 mates with one end of the upper locking groove 111. A gap is thus formed between the other end of the upper locking block 121 and the corresponding end of the upper locking groove 111. A limiting block with a matching structure is then inserted into this gap to fix the upper flat anvil 12 to the bottom of the upper anvil 11. See the attached instruction manual. Figure 5As shown, the lower anvil 2 consists of a detachable lower anvil seat 21 and a V-shaped anvil seat 22. The lower anvil seat 21 is fixed to the lower template of the press by bolts, and the V-shaped anvil seat 22 is located on top of the lower anvil seat 21. To facilitate the fixed connection between the V-shaped anvil seat 22 and the lower anvil seat 21 and for easy disassembly, a lower retaining groove 211 is provided on the top of the lower anvil seat 21. The lower retaining groove 211 is a dovetail groove, which is arranged laterally along the left and right length direction of the lower anvil seat 21, and the lower retaining groove 211 passes through the front and rear ends of the lower anvil seat 21. The V-shaped anvil seat 2... 2. A lower locking block 221 is provided at the bottom. The lower locking block 221 is a dovetail block, which is integrally formed with the V-shaped anvil 22 and can be horizontally inserted into the lower locking groove 211. To avoid the lower locking groove 211 and the lower locking block 221 from colliding and interfering when the V-shaped anvil 22 and the lower anvil 21 are assembled vertically, the top width of the lower locking groove 211 is greater than the bottom width of the lower locking block 221. To ensure the installation accuracy of the V-shaped anvil 22 on the top of the lower anvil 21, a lower fixing point is provided at the top of the lower anvil 21 on the left and right sides of the lower locking groove 211. The lower fixed center groove 212 extends horizontally through both ends of the lower anvil 21. The bottom of the V-shaped anvil 22 is provided with lower fixed center blocks 225 located on either side of the lower locking block 221. The lower fixed center blocks 225 correspond vertically to the lower fixed center groove 212 and are vertically interlocked with it. When the V-shaped anvil 22 is assembled on the lower anvil 21, the lower fixed center blocks 225 and the lower fixed center groove 212 are first vertically interlocked together, and simultaneously the lower locking block 221 is inserted into the lower locking slot 211. After the V-shaped anvil 22 and the lower anvil 21 are assembled vertically, the V-shaped anvil 22 is moved horizontally to the left or right, so that one end of the lower locking block 221 at the bottom of the V-shaped anvil 22 engages with one end of the lower locking groove 211. At this time, a gap is formed between the other end of the lower locking block 221 and the corresponding end of the lower locking groove 211. Then, a matching limiting block is inserted into this gap to fix the V-shaped anvil 22 on the top of the lower anvil 21. It should be noted that the upper flat anvil 12 corresponds vertically to the V-shaped anvil 22. See the appendix of the instruction manual. Figure 3 and 5 As shown, the V-shaped anvil 22 has an upward-opening V-shaped groove 226 at its center, which is connected front to back. The part of the metal forging blank 4 to be processed is placed in the V-shaped groove 226. Specifically, to improve the versatility of this embodiment and enable it to have the functions of drawing and separating materials, the bottom center of the V-shaped anvil 226 has an upward-opening V-shaped groove 222. A V-shaped insert 3 is provided in the V-shaped groove 222 to fit into it. See the appendix of the specification. Figure 6As shown, the top of the V-shaped insert 3 is provided with a V-shaped groove 32. The V-shaped insert 3 is used for drawing the forging. The heated forging can be placed in the V-shaped groove 32. In order to better match the placement of the forging, the bottom of the V-shaped groove 32 has an arc-shaped structure. It should be noted that V-shaped inserts 3 with different opening angles of the V-shaped groove 32 can be embedded in the V-shaped insert 222. The appropriate V-shaped insert 3 can be selected according to the forging of different specifications, thereby improving its adaptability and reducing the overall processing and manufacturing cost of the V-shaped anvil.

[0032] To enable the universal V-shaped anvil of this utility model to have a material dispensing function, please refer to the appendix to the specification. Figure 7 As shown, the V-groove 32 is provided with a cutting edge 33 that conforms to its outline shape. The cross-section of the cutting edge 33 is triangular. It is integrated with the V-shaped insert 3 to form a material separating insert 5. The material separating insert 5 is an independent functional body used for separating the forging blank 4. In addition to having a cutting edge 33, its structure is the same as that of the V-shaped insert 3 and it can be embedded in the V-groove 222.

[0033] To ensure that the V-shaped insert 3 can be securely installed within the V-shaped groove 222, please refer to the instruction manual appendix. Figure 3 As shown, the V-shaped groove 222 has symmetrical fixing grooves 223 on both sides of its top, and the bottom of the fixing groove 223 is provided with a threaded connection hole; see the attached specification. Figure 3 As shown in Figures 6 and 7, the top two ends of the V-shaped insert 3 are provided with symmetrical flanged joints 31. The flanged joints 31 are embedded in the fixing groove 223. The top of the flanged joints 31 is provided with a fixing hole that is vertically connected. The fixing hole and the threaded connection hole are vertically aligned and connected together by screws. Correspondingly, the V-shaped insert 3 and the material separating blade insert 5, which has a similar overall structure to the V-shaped insert 3, are fixedly connected to the V-shaped groove 222 on the V-shaped anvil 22 by screws, which also facilitates disassembly. For easy removal of the V-shaped insert 3 or the material separating blade insert 5 from the V-shaped groove 222, please refer to the appendix of the instruction manual. Figure 3 As shown, the bottom center of the V-shaped groove 222 is provided with a top hole 224 that penetrates downward through the bottom of the V-shaped anvil 22. When disassembling the V-shaped insert 3 or the material separating knife insert 5, the V-shaped anvil 22 is moved horizontally out of the lower anvil 21, at least so that the part of the V-shaped anvil 22 with the top hole 224 is moved out of the lower anvil 21. Then, the push rod that is engaged with the top hole 224 is inserted into the top hole 224 from below the bottom of the V-shaped anvil 22, and the V-shaped insert 3 or the material separating knife insert 5 in the V-shaped groove 222 is pushed upward out of the top of the V-shaped anvil 22, thereby realizing the disassembly of the V-shaped insert 3 or the material separating knife insert 5.

[0034] During the material separation process, a material separation blade insert 5 is installed in the V-shaped groove 222. The manipulator clamps the forging blank 4 and places it on the cutting edge 33 of the material separation blade insert 5. The press drives the upper anvil 1 to press down, and the operator rotates the forging blank 4. The cutting edge 33 marks a circle of cutting marks on the forging blank 4, thus separating the material. When using this structure for material separation, because the cutting edge 33 is an arc-shaped structure and is relatively long, the forging blank 4 often only needs to be rotated 3 times to complete one circle of material separation. During rotation, the groove of the already pressed mark on one side can be used for positioning with the cutting edge 33, which greatly increases efficiency and eliminates the need for workers to get close to operate, reducing the labor intensity of workers.

[0035] This universal V-shaped anvil has a simple structure. The upper anvil 1 and lower anvil 2 are designed to be detachable, which facilitates component replacement and local replacement after component damage, thus saving on usage costs. V-shaped inserts 22 or dividing blade inserts 5 can be installed on the V-shaped anvil base 22 according to processing needs. By installing V-shaped inserts 22, the forgings can be elongated. By installing dividing blade inserts 5, the forging blanks can be divided, ensuring the accuracy of the division. It has strong versatility, improves production efficiency, and reduces labor costs and labor intensity.

[0036] It should be emphasized that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
