Description

Technical Field

[0001] This utility model relates to the field of forging tool technology, specifically an adjustable forging frame. Background Technology

[0002] In valve forging, the mandrel frame is a key tool for expanding and forming annular forgings. Shaped like a horse, it is used to fit the heated billet onto the mandrel during forging. Pressure is applied to the outer circumference of the billet using a forging hammer or press, while the billet rotates with the mandrel, causing the metal to stretch evenly and achieving a thinner wall and larger inner diameter. The use of the mandrel frame effectively controls the roundness and dimensional accuracy of the annular forgings, preventing uneven deformation during forging. It is particularly suitable for machining high-precision annular structures such as sealing surfaces and connecting parts in valve manufacturing, significantly improving the structural strength and assembly compatibility of valve components. It is an important auxiliary tool for achieving efficient forming of annular parts in valve forging processes.

[0003] The existing forging frames for valve rings have fixed lengths and outer diameters for the mandrels they are used with. Therefore, when different lengths and outer diameters of mandrels are needed to forge valve rings of different sizes, different forging frames are required, resulting in low applicability. To address this, we propose an adjustable forging frame. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable forging frame that can be adjusted according to mandrels of different lengths and outer diameters to be suitable for forging valve ring parts of different sizes, thus improving applicability. This solves the problem that existing forging frames for valve ring parts have fixed mandrel lengths and outer diameters, requiring different frames to be used when forging valve ring parts of different sizes with mandrels of different lengths and outer diameters, resulting in low applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable forging frame, comprising a base plate and a support block. Sliding plates are slidably mounted on both sides of the upper surface of the base plate. A through groove is provided on the lower surface of each of the two sliding plates. Nuts are fixedly mounted on the two sliding plates above the through grooves. A screw is movably inserted into each of the two nuts, and a friction plate is rotatably connected to one end of the screw inside the through groove. Supporting vertical plates are fixedly mounted on the upper surface of each of the two sliding plates near their inner sides. Slots are provided on the upper surface of each of the two supporting vertical plates. An arc-shaped groove is provided on the upper surface of the support block. An insert plate is fixedly mounted on the lower surface of the support block, and the insert plate is located inside the slot.

[0006] Preferably, the front and rear surfaces of the base plate are provided with straight grooves, and the front and rear surfaces of the two sliding plates are fixedly installed with L-shaped plates, with the ends of the L-shaped plates located inside the straight grooves. The sliding plates slide through the L-shaped plates and the straight grooves, and the straight grooves are located on the front and rear surfaces of the base plate. In this way, during the forging process of the valve ring, the falling debris is not easy to enter the straight grooves.

[0007] Preferably, scrapers are fixedly installed on the inner walls of the two through grooves near the sides of the friction plate, and the lower surface of the scraper is in contact with the upper surface of the base plate. During the movement of the sliding plate, the scraper can scrape off the debris remaining on the upper surface of the base plate to avoid hindering the contact between the friction plate and the base plate and reducing the firmness of the sliding plate after it is fixed.

[0008] Preferably, a triangular plate is fixedly installed on the upper surface of both sliding plates near the outer side of the supporting vertical plate, and the inner side of the triangular plate is fixedly connected to the outer side of the supporting vertical plate. The triangular plate improves the structural strength between the supporting vertical plate and the sliding plate.

[0009] Preferably, each of the two supporting vertical plates has a through hole near the upper surface on its inner side, and a fixing bolt is inserted into the through hole. The insert plate has a through hole on its inner side, and the fixing bolt passes through the through hole. The insert plate is fixed inside the slot by the fixing bolt to prevent the insert plate from slipping out of the slot.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting a base plate, sliding plate, nut, screw, through groove, friction plate, support vertical plate, slot, support block, arc groove, and insert plate, achieves the ability to adjust the frame according to mandrels of different lengths and outer diameters, thus adapting to the forging of valve ring parts of different sizes and improving applicability. The two sliding plates move on the upper surface of the base plate to adjust the distance between the two support vertical plates to accommodate mandrels of different lengths. After the sliding plates are adjusted, the screw is turned to make the friction plate contact the base plate and fix the sliding plates. For mandrels of different outer diameters, support blocks of different sizes can be replaced by inserting the insert plate into the slot to match the size of the arc groove with the outer diameter of the mandrel, thereby adapting to mandrels of different lengths and outer diameters and forging valve ring parts of different sizes.

[0012] 2. By setting a scraper, this utility model can remove the debris remaining on the upper surface of the base plate during the movement of the sliding plate, so as to avoid hindering the contact between the friction plate and the base plate and reducing the firmness of the sliding plate after it is fixed.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0019] like Figures 1-4As shown, this utility model proposes an adjustable forging frame, including a base plate 1 and a support block 7. Sliding plates 4 are slidably installed on both sides of the upper surface of the base plate 1. Straight grooves 12 are provided on both the front and rear surfaces of the base plate 1. L-shaped plates 11 are fixedly installed on both the front and rear surfaces of the two sliding plates 4, with the ends of the L-shaped plates 11 located inside the straight grooves 12. The sliding plates 4 slide through the L-shaped plates 11 and the straight grooves 12. Since the straight grooves 12 are located on the front and rear surfaces of the base plate 1, debris falling during the forging of the valve ring is less likely to enter the straight grooves 12. Through grooves 3 are provided on the lower surfaces of the two sliding plates 4, extending to both sides of the sliding plates 4. Nuts 10 are fixedly installed on the two sliding plates 4 above the through grooves 3. Screws 9 are movably inserted into the two nuts 10, penetrating the sliding plates 4, with one end of the screw 9 inside the through groove 3 rotatably connected to... There is a friction plate 13, and the screw 9 is rotatably connected to the friction plate 13 via a bearing. Supporting vertical plates 5 are fixedly installed on the upper surface of the two sliding plates 4 near the inner side. The supporting vertical plates 5 are perpendicular to the sliding plates 4. The upper surface of the two supporting vertical plates 5 is provided with a slot 18. The upper surface of the support block 7 is provided with an arc-shaped groove 8. The end of the spindle is placed inside the arc-shaped groove 8 to support the spindle. The lower surface of the support block 7 is fixedly installed with an insert plate 14, and the insert plate 14 is located inside the slot 18. The inner side of the two supporting vertical plates 5 near the upper surface is provided with a through hole 16. The through hole 16 extends to the outer side of the supporting vertical plate 5, and a fixing bolt 15 is inserted into the through hole 16. The inner side of the insert plate 14 is provided with a through hole 17. The through hole 17 extends to the outer side of the insert plate 14, and the fixing bolt 15 passes through the through hole 17. The fixing bolt 15 fixes the insert plate 14 inside the slot 18 to prevent the insert plate 14 from slipping out of the slot 18.

[0020] In use, the two sliding plates 4 move on the upper surface of the base plate 1 to adjust the distance between the two supporting vertical plates 5 to accommodate mandrels of different lengths. After the sliding plates 4 are adjusted, the screw 9 is turned to make the friction plate 13 contact the base plate 1, thus fixing the sliding plates 4. For mandrels of different outer diameters, support blocks 7 of different sizes can be replaced by inserting the insert plate 14 into the slot 18 to make the size of the arc groove 8 match the outer diameter of the mandrel, thereby adapting to mandrels of different lengths and outer diameters, and forging valve ring parts of different sizes. Example 2

[0021] like Figures 1-3As shown, the adjustable forging frame proposed in this utility model, compared with the first embodiment, further includes two scrapers 2 fixedly installed on the inner walls of the through grooves 3 near the friction plate 13 on both sides, and the lower surface of the scraper 2 is in contact with the upper surface of the base plate 1. Triangular plates 6 are fixedly installed on the upper surfaces of the two sliding plates 4 near the outer side of the supporting vertical plate 5, and the inner side of the triangular plate 6 is fixedly connected to the outer side of the supporting vertical plate 5. The triangular plate 6 improves the structural strength between the supporting vertical plate 5 and the sliding plate 4.

[0022] In this embodiment, during the movement of the sliding plate 4, the scraper 2 can scrape off the debris remaining on the upper surface of the base plate 1 to avoid hindering the contact between the friction plate 13 and the base plate 1 and reducing the firmness of the sliding plate 4 after it is fixed.

[0023] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
