Description

Technical Field

[0001] The present invention relates to the technical field of die forging, and specifically relates to a die forging device with adjustable forging surface and its forging method. Background Art

[0002] Forging is the combination of forging and stamping. It is a forming processing method that uses the hammer head, anvil block, punch of a forging machine or applies pressure to the blank through a die to make it plastically deformed, so as to obtain a workpiece with the required shape and size. During the forging process of a workpiece, a forging die and a forging device are required.

[0003] In the prior art, such as the "forging press for a forging die" with the Chinese patent number: CN219335836U, it includes a box body and a mounting seat arranged on the box body. A bracket is fixedly installed at the top of the box body. An installation groove is opened at the top of the bracket. A hydraulic rod is fixedly installed on the inner wall of the installation groove inside the bracket. The vertically downward telescopic end of the hydraulic rod is fixedly installed with a punch head.

[0004] However, in the above patent, although the forging surface of the die blank can be adjusted to a certain extent, the moving direction of the mounting seat is too single and can only move back and forth in one direction. If the direction where the position of the die blank needs to be forged and the moving direction of the mounting seat are not on the same straight line, it is necessary to continuously adjust the position of the die blank on the processing table. Moreover, the clamping device on the mounting seat is driven by a screw rod. If the number of forging times of the die in the processing factory is large, workers need to constantly turn the screw rod to load and take the workpiece, which increases the labor intensity of the workers, is inconvenient, and has limitations in use.

If the position of the forging surface needs to be adjusted, it is necessary to continuously adjust the position of the workpiece on the processing table. Moreover, the clamping device on the mounting seat is driven by a screw rod. If the number of forging times of the die in the processing factory is large, workers need to constantly turn the screw rod to load and take the workpiece, which is inconvenient and has limitations in use.

[0006] To achieve the above object, the present invention provides the following technical solutions: A forging surface adjustable die forging device and its forging method, including a base, a first slide bar is fixedly connected above the base, a slider is slidably connected to the outer wall of the first slide bar, an installation plate is slidably connected to the outer side wall of the slider, a first moving groove and a second moving groove are opened on one side of the installation plate, two places in the middle above the base are rotatably connected with rotating rods, a first gear is fixedly connected to the outer walls of the two rotating rods, a disc is fixedly connected to one end of the two rotating rods, an extrusion block is fixedly connected to one side of the two discs, one extrusion block is located inside the first moving groove, and the other extrusion block is located inside the second moving groove. Two driving motors are fixedly connected to two places in the middle above the base, and the output ends of the two driving motors are fixedly connected with second gears. The diameter of the second gear is smaller than that of the first gear, and one side of the two second gears meshes with one side of the two first gears.

[0007] Preferably, a protective cover is fixedly connected above the installation plate, a reduction motor is fixedly connected inside the protective cover, a screw rod is fixedly connected to the output end of the reduction motor, a moving block is threadedly connected to the outer wall of the screw rod, and the moving block is slidably connected to one side inside the protective cover.

[0008] Preferably, a connecting rod is rotatably connected to one side inside the protective cover, a support rod is rotatably connected to one end of the connecting rod, one end of the support rod is rotatably connected to the moving block, and the other end of the support rod is rotatably connected to a fixed rod.

[0009] Preferably, a second slide bar is slidably connected to one side of the fixed rod, a limiting hole is opened in the middle of one side of the second slide bar, and a clamping block is fixedly connected to one side of the second slide bar.

[0010] Preferably, a limiting rod is slidably connected to one side of the fixed rod, and one end of the limiting rod is clamped inside the limiting hole.

[0011] Preferably, an installation frame is fixedly connected to one side of the fixed rod, and the limiting rod is slidably connected to the installation frame.

[0012] Preferably, a spring is installed inside the installation frame, the limiting rod is located inside the spring, and one end of the spring is fixedly connected to the outer wall of the limiting rod.

[0013] Preferably, a safety block is fixedly connected to one end of the limiting rod, a fixed block is fixedly connected to one side of the safety block, and a pull ring is fixedly connected to one side of the fixed block.

[0014] Preferably, a mounting frame is fixedly connected above the base, a reinforcing rib is fixedly connected below one side of the mounting frame, one side of the reinforcing rib is fixedly connected to one side of the base, a hydraulic cylinder is fixedly connected above the mounting frame, a forging head is fixedly connected to the output end of the hydraulic cylinder, a mounting seat is fixedly connected above the mounting plate, and support feet are fixedly connected below the base.

[0015] A forging method for an adjustable forging surface die includes the following steps:

[0016] S1. Place the die blank to be forged on the top of the mounting seat, then start the reduction motor. The reduction motor drives the screw to rotate. When the screw rotates, it will drive the moving block to move. When the moving block moves, it will drive the connecting rod, the support rod and the fixed rod to rotate. One ends of the two fixed rods approach each other, that is, the two clamping blocks approach each other, so as to complete the clamping of the die blank.

[0017] S2. After the die blank is clamped, if it is necessary to forge different positions of the die blank, start the driving motor. The rotation of the output end of the driving motor will drive the first gear and the second gear to rotate. Because one side of the first gear and the second gear meshes, and the upper part of the rotating rod is fixedly connected to the disc, when the driving motor rotates, it will drive the disc to rotate. When the disc rotates, the extrusion block will extrude the inner walls of the first moving groove and the second moving groove. Because the opening directions of the first moving groove and the second moving groove are perpendicular to each other, that is, by starting two driving motors to drive two discs to rotate, the mounting plate can be moved in two different directions, so as to achieve the purpose of forging different positions of the die blank.

[0018] S3. After the position of the die blank is adjusted, start the hydraulic cylinder. The output end of the hydraulic cylinder moves downward, which will drive the forging head to move downward and extrude the die blank, so as to complete the forging of the die blank.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In the present invention, after the driving motor runs, through the rotation of the disc, the extrusion block above the disc can extrude the inner wall of the moving groove. Because the opening directions of the two moving grooves are perpendicular to each other, the rotation of the two discs can drive the mounting plate and the mounting seat to move in two directions and the moving directions are perpendicular to each other. Due to the two-way movement of the mounting plate, when debugging the forging surface of the die blank, that is, forging different positions of the die blank, through the two-way movement of the mounting plate, the position of the die blank can be adjusted more conveniently, so as to debug the forging surface of the die blank, and the use convenience of the device is improved.

[0021] 2. In the present invention, through the design of the clamping mechanism, when workers clamp the mold blank, they do not need to rotate the bolt back and forth for many turns, reducing the labor intensity of the workers. At the same time, due to the opposite movement of the two clamping plates, the mold blank can always be in the middle position of the mounting seat, reducing the possibility of the mold blank offset during clamping and improving the use stability of the device.

[0022] 3. In the present invention, since the clamping block and the fixing rod are slidably connected and then clamped in the middle, through this design, when replacing the clamping block after one side of it is worn after long-term use, only need to pull the pull ring to release the clamping of the limiting rod in the limiting hole, which improves the use convenience of the device.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. Embodiment 1

[0033] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、and Figure 5 As shown in, a forging device with adjustable forging surface and its forging method include a base 1. A first sliding bar 11 is fixedly connected above the base 1. A slide block 12 is slidably connected to the outer wall of the first sliding bar 11. A mounting plate 13 is slidably connected to the outer side wall of the slide block 12. A first moving groove 14 and a second moving groove 15 are formed on one side of the mounting plate 13. Two places in the middle above the base 1 are rotatably connected with rotating rods 16. First gears 17 are fixedly connected to the outer walls of the two rotating rods 16. One ends of the two rotating rods 16 are fixedly connected with discs 18. Extrusion blocks 19 are fixedly connected to one side of the two discs 18. One extrusion block 19 is located inside the first moving groove 14, and the other extrusion block 19 is located inside the second moving groove 15. Two driving motors 2 are fixedly connected to two places in the middle above the base 1. Second gears 21 are fixedly connected to the output ends of the two driving motors 2. The diameter of the second gear 21 is smaller than that of the first gear 17. One side of the two second gears 21 meshes with one side of the two first gears 17.

[0034] In this embodiment, if it is necessary to forge different positions of the mold blank, the driving motor 2 is started. The rotation of the output end of the driving motor 2 will drive the first gear 17 and the second gear 21 to rotate. Since one side of the first gear 17 and the second gear 21 is meshed, and the upper part of the rotating rod 16 is fixedly connected to the disc 18, when the driving motor 2 rotates, the disc 18 will be driven to rotate. When the disc 18 rotates, the extrusion block 19 will extrude the inner walls of the first moving groove 14 and the second moving groove 15. Since the opening directions of the first moving groove 14 and the second moving groove 15 are perpendicular to each other, after the driving motor 2 operates, through the rotation of the disc 18, the extrusion block 19 above the disc 18 can extrude the inner walls of the first moving groove 14 and the second moving groove 15. Since the opening directions of the two moving grooves are perpendicular to each other, the rotation of the two discs 18 can drive the mounting plate 13 and the mounting seat 39 to move in two directions and the moving directions are perpendicular to each other. Since the mounting plate 13 moves bidirectionally, when debugging the forging surface of the mold blank, that is, forging different positions of the mold blank, through the bidirectional movement of the mounting plate 13, the position of the mold blank can be adjusted more conveniently, so as to more conveniently debug the forging surface of the mold blank, improving the usability of this device. Embodiment Two

[0035] Figure 1 and Figure 6 As shown in Figure 6 , a protective cover 22 is fixedly connected above the mounting plate 13. A reduction motor 293 is fixedly connected inside the protective cover 22. The output end of the reduction motor 293 is fixedly connected with a screw rod 292. A moving block 26 is threadedly connected to the outer wall of the screw rod 292. The moving block 26 is slidably connected to one side inside the protective cover 22. One side inside the protective cover 22 is rotatably connected with a connecting rod 23. One end of the connecting rod 23 is rotatably connected with a support rod 24. One end of the support rod 24 is rotatably connected with the moving block 26. The other end of the support rod 24 is rotatably connected with a fixed rod 25. A second sliding strip 27 is slidably connected to one side of the fixed rod 25. A limiting hole 28 is opened in the middle of one side of the second sliding strip 27. A clamping block 291 is fixedly connected to one side of the second sliding strip 27.

[0036] In this embodiment, the mold blank to be forged is placed on the top of the mounting seat 39. Subsequently, the reduction motor 293 is started. The reduction motor 293 drives the screw rod 292 to rotate. When the screw rod 292 rotates, it will drive the moving block 26 to move. When the moving block 26 moves, it will drive the connecting rod 23, the support rod 24 and the fixed rod 25 to rotate. One ends of the two fixed rods 25 approach each other, that is, the two clamping blocks 291 approach each other, thus completing the clamping of the mold blank. Through the opposite movement between the two clamping blocks 291, compared with the traditional bolt clamping, the mold blank can be clamped more quickly. Embodiment Three

[0037] According to Figure 1 、Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown in Figure 6 , Figure 7 , Figure 8 , a limiting rod 3 is slidably connected to one side of a fixing rod 25. One end of the limiting rod 3 is clamped inside a limiting hole 28. An installation frame 29 is fixedly connected to one side of the fixing rod 25. The limiting rod 3 is slidably connected to the installation frame 29. A spring 31 is installed inside the installation frame 29. The limiting rod 3 is located inside the spring 31. One end of the spring 31 is fixedly connected to the outer wall of the limiting rod 3. One end of the limiting rod 3 is fixedly connected to a safety block 32. One side of the safety block 32 is fixedly connected to a fixing block 33. One side of the fixing block 33 is fixedly connected to a pull ring 34. An installation frame 35 is fixedly connected above the base 1. A reinforcing rib 36 is fixedly connected to the lower part of one side of the installation frame 35. One side of the reinforcing rib 36 is fixedly connected to one side of the base 1. A hydraulic cylinder 37 is fixedly connected above the installation frame 35. The output end of the hydraulic cylinder 37 is fixedly connected to a forging head 38. An installation seat 39 is fixedly connected above the installation plate 13. Support feet 4 are fixedly connected below the base 1.

[0038] In this embodiment, if one side of the clamping block 291 is worn after long-term use and needs to be replaced, pull the pull ring 34. After the pull ring 34 is pulled, the limiting rod 3 will squeeze one end of the spring 31. At this time, the spring 31 will undergo elastic deformation and contract, and the limiting rod 3 will also slide inside the installation frame 29. After one end of the limiting rod 3 completely disengages from the inside of the limiting hole 28, the limit of the second sliding strip 27 in the fixing rod 25 can be released, and then the clamping block 291 can be pulled out from the inside of the fixing rod 25. Embodiment 4

[0039] A forging method for a forging surface adjustable die includes the following steps:

[0040] Step 1: Place the die blank to be forged on the top of the installation seat 39. Then start the reduction motor 293. The reduction motor 293 drives the screw rod 292 to rotate. When the screw rod 292 rotates, it will drive the moving block 26 to move. When the moving block 26 moves, it will drive the connecting rod 23, the support rod 24 and the fixing rod 25 to rotate. One ends of the two fixing rods 25 approach, that is, the two clamping blocks 291 approach each other, so as to complete the clamping of the die blank.

[0041] Step 2: After the mold blank is clamped, if it is necessary to forge different positions of the mold blank, start the driving motor 2. The rotation of the output end of the driving motor 2 will drive the first gear 17 and the second gear 21 to rotate. Since one side of the first gear 17 and the second gear 21 is meshed, and the upper part of the rotating rod 16 is fixedly connected to the disc 18, when the driving motor 2 rotates, it will drive the disc 18 to rotate. When the disc 18 rotates, the extrusion block 19 will extrude the inner walls of the first moving groove 14 and the second moving groove 15. Since the opening directions of the first moving groove 14 and the second moving groove 15 are perpendicular to each other, that is, by starting two driving motors 2 to drive two discs 18 to rotate, the movement of the mounting plate 13 in different directions can be completed, so as to achieve the purpose of forging different positions of the mold blank.

[0042] Step 3: After the position of the mold blank is adjusted, start the hydraulic cylinder 37. The output end of the hydraulic cylinder 37 moves downward, which will drive the forging head 38 to move downward and extrude the mold blank, thereby completing the forging of the mold blank.

[0043] Usage method and working principle of this device: Before use, the user first checks whether this device is damaged. After confirming that this device is not damaged, place the mold blank to be forged on the top of the mounting seat 39. Then start the reduction motor 293. The reduction motor 293 drives the screw rod 292 to rotate. When the screw rod 292 rotates, it will drive the moving block 26 to move. When the moving block 26 moves, it will drive the connecting rod 23, the support rod 24 and the fixed rod 25 to rotate. One ends of the two fixed rods 25 approach each other, that is, the two clamping blocks 291 approach each other, thereby completing the clamping of the mold blank. After the mold blank is clamped, if it is necessary to forge different positions of the mold blank, start the driving motor 2. The rotation of the output end of the driving motor 2 will drive the first gear 17 and the second gear 21 to rotate. Since one side of the first gear 17 and the second gear 21 is meshed, and the upper part of the rotating rod 16 is fixedly connected to the disc 18, when the driving motor 2 rotates, it will drive the disc 18 to rotate. When the disc 18 rotates, the extrusion block 19 will extrude the inner walls of the first moving groove 14 and the second moving groove 15. Since the opening directions of the first moving groove 14 and the second moving groove 15 are perpendicular to each other, that is, by starting two driving motors 2 to drive two discs 18 to rotate, the movement of the mounting plate 13 in different directions can be completed, so as to achieve the purpose of forging different positions of the mold blank. After the position of the mold blank is adjusted, start the hydraulic cylinder 37. The output end of the hydraulic cylinder 37 moves downward, which will drive the forging head 38 to move downward and extrude the mold blank, thereby completing the forging of the mold blank.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
