Description

Technical Field

[0001] The invention relates to the technical field of flange forging, and in particular to a forging die for an automobile intake and exhaust connection flange. Background Art

[0002] As the connecting parts of the engine intake and exhaust pipes, the intake and exhaust connecting flanges are usually subjected to high temperatures, pressures and vibrations. Therefore, strict requirements are placed on their mechanical properties and durability during design and manufacturing. In order to improve the strength of the flanges, extend their service life and ensure the reliability of the connection, the traditional casting process has been gradually replaced by the forging process. The forging process has the advantages of improving material density and strengthening metal structure, which can significantly improve the mechanical properties of the flanges, especially in terms of compressive strength, corrosion resistance and high temperature resistance. Therefore, in response to the production needs of automobile intake and exhaust connecting flanges, high-precision forging molds have been developed to achieve efficient and large-scale production of flange components.

[0003] A Chinese patent (publication number: CN117000937B) discloses a forging die for neck flange forgings. This device uses a forging head to press the blank into the die cavity, preventing die jumps during the forging process. This improves the stability of the blank during the forging process and the quality of the resulting neck flange forgings. However, the device cannot adjust the forging die specifications before actual use, resulting in the die being capable of forging only a single flange model. This inability to reasonably adjust the die specifications based on production needs increases the limitations of the forging die. Furthermore, the need to manufacture a larger number of forging die models for different flange specifications increases production costs. Summary of the Invention

[0007] Furthermore, the surface of the adjusting gear is meshed with a latching tooth, and the upper and lower surfaces of the latching tooth are fixedly connected to a limiting block 1, and the limiting block 1 is slidably plugged into the base.

[0008] Furthermore, two groups of mounting holes are opened inside the adjusting ring, and the inner walls of the two groups of mounting holes are fixedly connected with fixing rods. The upper surface of the adjusting ring is fitted with an anti-sticking plate, and the anti-sticking plate is fitted with the inner wall of the mounting hole, and the anti-sticking plate is clamped with the fixing rod.

[0009] Furthermore, two groups of columns are fixedly installed on the upper surface of the base, the upper ends of the two groups of columns are fixedly connected to fixed blocks, the surface of the base is fixedly connected to a connecting block, and the connecting block is fixedly connected to the fixing block.

[0010] Furthermore, a bracket is fixedly installed on the lower surface of the fixed block, a forging hammer is fitted on the lower surface of the bracket, a receiving block 1 is fixedly connected to the upper surface of the forging hammer, two groups of clamping blocks 2 are fixedly connected to the surface of the receiving block 1, and both groups of clamping blocks 2 are fitted with the inner wall of the bracket.

[0011] Furthermore, a driven gear is fixedly mounted on the surface of the forging hammer, a servo motor is fixedly mounted on the upper surface of the bracket, a driving gear is fixedly connected to the output shaft of the servo motor, and the driving gear is meshed with the forging hammer.

[0012] Furthermore, a power machine is fixedly mounted on the upper surface of the fixed block, and multiple groups of clamping blocks 1 are fixedly connected to the surface of the receiving block 1, and the multiple groups of clamping blocks 1 are all in contact with the inner wall of the output end of the power machine.

[0014] Furthermore, a controller is fixedly mounted on the surface of the base.

[0015] The beneficial effects of the present invention are as follows: 1. When the present invention adjusts the specifications of the mold, an air flow is introduced into the interior of the receiving block 2 through the air pump, and the air flow enters the interior of the telescopic tube through the receiving block 2. As the air pump continues to introduce air, the air pressure inside the telescopic tube gradually increases, causing the telescopic tube to extend. The extension of the telescopic tube drives the two groups of telescopic blocks to extend outward at the same time, causing the spring to stretch, so that the telescopic blocks fit with the bottoms of the multiple groups of adjustment rings, and the hydraulic rod 1 is started. The hydraulic rod 1 drives the fixed plate, the receiving block 2, the telescopic blocks and the multiple groups of adjustment rings to move vertically upward, thereby adjusting the size of the forged flange. The tooth plate is driven to move horizontally by rotating the adjustment gear, so that the bottom surface of the tooth plate fits with the output end of the hydraulic rod 2, and the adjustment is continued by rotating. The gear makes the tooth plate fit with the bottom surface of multiple groups of adjustment rings, and the hydraulic rod 2 is started. The tooth plate and multiple groups of adjustment rings are driven by the hydraulic rod 2 to move vertically upward, thereby adjusting the diameter of the forged flange. The height difference generated by the vertical upward movement of the inner adjustment component and the outer adjustment component is used to adjust whether the flange has a neck and the neck depth. The setting of this component effectively avoids the problem that the die cannot be adjusted before flange forging, and can achieve the effect of adjusting the diameter, caliber and neck depth of the forged flange. At the same time, it improves the versatility of the forging die, reduces the limitations of flange forging, and can also fine-tune the forging die according to production needs during actual use, thereby reducing the forging cost of the flange.

[0016] 2. When the forging hammer is replaced according to the present invention, first, the forging hammer is placed at the bottom of the bracket, and the forging hammer is rotated so that the clamping block 2 fixedly connected to the surface of the clamping block 1 rotates to the inner wall of the bracket, so that the driven gear is meshed with the driving gear, the power machine is started, and the output end of the power machine is gradually fitted with the surface of the receiving block 1. When the output end of the power machine is fitted with the surface of the bracket, the servo motor is started, and the driving gear is driven by the servo motor to rotate, so that the driven gear meshed with the surface of the driving gear drives the forging hammer to rotate following the driving gear, so that the multiple groups of clamping blocks 1 fixedly connected to the surface of the receiving block 1 are all fitted with the inner wall of the output end of the power machine, and at the same time, the clamping block 2 is separated from the inner wall of the bracket, so that the forging hammer can move vertically with the power machine, thereby forging the flange through the forging hammer. The arrangement of this assembly effectively avoids the problem of being unable to disassemble and assemble the forging hammer during flange forging, and can achieve the effect of replacing the forging hammer accordingly following the change of the mold, while improving the efficiency of flange forging and reducing mold loss.

The receiving seat 34 is fixedly connected to the base 1, the air pump 36 is fixedly connected to the receiving seat 34, the receiving block 2 35 is fixedly connected to the air pump 36, and one end of the telescopic tube 38 is fixedly connected to the receiving block 2 35 is fixedly connected, the other end of the telescopic tube 38 is fixedly connected to the telescopic block 32, the telescopic block 32 is fixedly connected to the receiving block 2 35, one end of the spring 39 is fixedly connected to the receiving block 2 35, the other end of the spring 39 is fixedly connected to the telescopic block 32, the fixed plate 33 is fixedly connected to the receiving block 2 35, the fixed plate 33 is fitted with the telescopic block 32, the hydraulic rod 1 37 is fixedly connected to the receiving seat 34, the output end of the hydraulic rod 1 37 is fixedly connected to the fixed plate 33, and the adjusting ring 31 is fitted with the base 1; An external adjustment assembly 5 is provided inside the base 1 , and the external adjustment assembly 5 includes an adjustment gear 53 , a tooth plate 54 and a hydraulic rod 55 .

[0021] When forging the flange, the diameter, caliber and neck depth of the flange need to be adjusted according to the use requirements to meet different use requirements. When adjusting the mold specifications, air is introduced into the interior of the receiving block 2 35 through the air pump 36, and the air enters the interior of the telescopic tube 38 through the receiving block 2 35. As the air pump 36 continues to be introduced, the air pressure inside the telescopic tube 38 gradually increases, causing the telescopic tube 38 to extend. The extension of the telescopic tube 38 drives the two groups of telescopic blocks 32 to extend outward at the same time, causing the spring 39 to stretch, so that the telescopic block 32 fits with the bottom of the multiple groups of adjustment rings 31, and the hydraulic rod 1 37 is started. The hydraulic rod 1 37 drives the fixed plate 33, the receiving block 2 35, the telescopic block 32 and the multiple groups of adjustment rings 31 to move vertically upward, thereby adjusting the caliber of the forged flange.

[0022] Example 2, as Figure 5 、 Figure 6 As shown, on the basis of the above embodiment, it also includes: the adjusting gear 53 is rotatably connected to the base 1, the hydraulic rod 2 55 is fixedly connected to the base 1, the tooth plate 54 is meshed with the adjusting gear 53, the tooth plate 54 is slidably connected to the base 1, the hydraulic rod 2 55 is fixedly connected to the base 1, the hydraulic rod 2 55 and the tooth plate 54 are located in the same vertical plane, the surface of the adjusting gear 53 is meshed with a tooth 52, the upper and lower surfaces of the tooth 52 are fixedly connected to the limit block 1 51, the limit block 1 51 is slidably plugged into the base 1, and the tooth plate 54 is driven to move horizontally by rotating the adjusting gear 53, so that the bottom surface of the tooth plate 54 fits with the output end of the hydraulic rod 2 55, and the adjustment is continued to be rotated. The gear 53 makes the tooth plate 54 fit with the bottom surface of the multiple groups of adjustment rings 31, and the hydraulic rod 2 55 is started. The hydraulic rod 2 55 drives the tooth plate 54 and the multiple groups of adjustment rings 31 to move vertically upward, thereby adjusting the diameter of the forged flange. When the adjustment of the tooth plate 54 is completed, the two groups of limit blocks 1 51 are both clamped to the inside of the base 1, so that the locking teeth 52 between the two groups of limit blocks 1 51 are clamped with the adjusting gear 53, thereby limiting the tooth plate 54 to avoid the tooth plate 54 from being offset during use. The height difference generated by the vertical upward movement of the inner adjustment component 3 and the outer adjustment component 5 is used to adjust whether the flange has a neck and the neck depth.

[0023] Example 3, as Figure 4As shown, on the basis of the above embodiment, it also includes that two groups of mounting holes 41 are opened inside the adjusting ring 31, and the inner walls of the two groups of mounting holes 41 are fixedly connected to the fixing rod 4, and the upper surface of the adjusting ring 31 is fitted with an anti-sticking plate 42, and the anti-sticking plate 42 is fitted with the inner wall of the mounting hole 41, and the anti-sticking plate 42 is clamped with the fixing rod 4. After the mold specifications are adjusted, the anti-sticking plates 42 of the same specifications are inserted into the inner walls of the mounting holes 41 according to the adjusted height of each group of adjusting rings 31, so that the anti-sticking plates 42 are installed on the upper surface of the adjusting ring 31. Since there are gaps between each group of adjusting rings 31, the anti-sticking plates 42 are used to prevent circular marks from being generated on the forged flange surface during forging.

[0024] Example 4, as Figure 1-Figure 3 As shown, on the basis of the above embodiment, it also includes: two groups of columns 11 are fixedly installed on the upper surface of the base 1, and the upper ends of the two groups of columns 11 are fixedly connected to the fixed blocks 14, the surface of the base 1 is fixedly connected to the connecting block 12, the connecting block 12 is fixedly connected to the fixed block 14, and the lower surface of the fixed block 14 is fixedly installed with a bracket 13, and the lower surface of the bracket 13 is fitted with a forging hammer 21, and the upper surface of the forging hammer 21 is fixedly connected with a receiving block 1 24, and the surface of the receiving block 1 24 is fixedly connected with two groups of clamping blocks 26, and the two groups of clamping blocks 26 are both fitted with the inner wall of the bracket 13. Through the sliding groove opened inside the bracket 13, the forging hammer 21 can be temporarily installed on the bottom of the bracket 13, thereby facilitating the installation of the forging hammer 21 and the power machine 15.

[0025] Example 5, as Figure 2 、 Figure 3 As shown, on the basis of the above embodiment, it also includes: a driven gear 2 is fixedly installed on the surface of the forging hammer 21, a servo motor 23 is fixedly installed on the upper surface of the bracket 13, and a driving gear 22 is fixedly connected to the output shaft of the servo motor 23, and the driving gear 22 is meshed with the forging hammer 21.

The surface of the base 1 is fixedly installed with a controller 16, and the driving gear 22 is driven to rotate by the servo motor 23, so that the driven gear 2 meshed with the surface of the driving gear 22 drives the forging hammer 21 to rotate with the driving gear 22. The connection relationship of the forging hammer 21 is controlled by the rotation of the driving gear 22, and whether the forging hammer 21 is fixed to the bottom of the bracket 13 or the output end of the power machine 15 is controlled by different rotation angles.

[0026] Example 6: Figure 7As shown, on the basis of the above embodiment, it also includes that the lower surface of the adjusting ring 31 is fixedly connected to the limiting rod 56, and the internal sliding connection of the limiting rod 56 is a plurality of groups of limiting blocks 57, and the limiting rod 56 is slidably connected to the base 1. When the adjusting ring 31 moves vertically, the limiting rod 56 fixedly connected to the bottom of the adjusting ring 31 moves vertically following the adjusting ring 31. When the adjustment of the adjusting ring 31 is completed, air flow is introduced into the limiting rod 56, so that the internal air pressure of the limiting rod 56 gradually increases, so that the plurality of groups of limiting blocks 57 slidably connected to the surface of the limiting rod 56 all move outward, so that the limiting blocks 57 are clamped to the inner wall of the base 1, thereby fixing the vertical position of the adjusting ring 31 and preventing the adjusting ring 31 from shifting during forging.
