Description

Technical Field

[0001] This utility model relates to the technical field of flange processing, and in particular to a forging blank device for flange processing. Background Technology

[0002] A flange is an important component used to connect pipes, valves, pumps and other equipment. A flange, also called a flange disc or flange, is a disc-shaped part that usually has several holes around its perimeter for fixing and connecting other components.

[0003] The forging equipment for flange processing requires placing the blank in the upper die for forging to form a round disc shape. Then, the disc-shaped blank is punched. However, punching in the market requires lifting the upper die and blank first, then placing the lower die at the bottom of the upper die, and then using the die core for punching to complete the initial processing of the flange blank. Since workers need to process large quantities of flange blanks of the same model, they need to frequently lift the upper die and blank, which increases the workload of the workers. Utility Model Content

[0004] The purpose of this utility model is to provide a forging blank device for flange processing in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a workbench and a housing of a forging device are included. The workbench is fixedly installed on the upper end of the housing by bolts. The bolt installation position can be adjusted as needed. A mold for manufacturing flanges is placed on the upper end of the workbench. A support assembly is installed inside the housing. An elastic device is installed in the middle of the support assembly. An auxiliary assembly for use with the mold is installed on the upper end of the elastic device.

[0006] The auxiliary component includes a movable column, the upper end of which is detachably fitted with a stepped column, which can be slidably connected. During the striking process, the upward movement of the stepped column will not detach it from the movable column. A through hole for use with the stepped column is opened in the middle of the worktable, and a round hole for use with the movable column is opened in the middle of the worktable. A fixing rod is fixedly installed at the lower end of the movable column, and a drive component is provided on one side of the movable column. This device only processes small flanges, and the size of this device can be adjusted according to actual needs.

[0007] Since the workbench is detachable and the stepped columns are replaceable, when different models of flanges need to be manufactured, the workers can first disassemble the workbench, then take out the stepped columns, and then replace them with different stepped columns, thereby increasing the ability to manufacture different models of products and improving the practicality of the device.

[0008] Furthermore, the support assembly includes two support columns fixedly installed inside the box. A support plate is fixedly installed in the middle of the support column, and a support rod is fixedly installed at the upper end of the support plate to cooperate with the fixing rod. The number and shape of the support columns can be increased as needed. The support columns are mainly used to support the top of the box and prevent the top of the box from deforming. The box is a thickened metal box.

[0009] During the hammering process, the fixed rod is positioned directly above the support rod, thus the support rod supports the fixed rod, the fixed rod supports the movable column, and the movable column supports the stepped column, preventing the stepped column from falling. Consequently, the upper surface of the stepped column is at the same height as the upper surface of the worktable. When a hole needs to be drilled, the operator controls the drive assembly to rotate the movable column, which in turn rotates the fixed rod, causing the fixed rod to detach from the upper end of the support rod. At this point, the operator places the mold core in the middle of the mold and uses hydraulic impact to push the mold core to the center of the flange blank. After hammering for a certain period, the mold core enters the circular hole in the center of the worktable, completing the initial processing of the flange blank. Because the stepped column in the middle of this device can be raised and lowered, the operator does not need to lift the mold; the mold core can be used directly, reducing the operator's workload.

[0010] Furthermore, the elastic device includes a guide cylinder fixedly installed in the middle of the support plate. A movable block is slidably and rotatably installed inside the guide cylinder. A guide rod is fixedly installed at the upper end of the movable block. A first spring is placed between the lower end of the movable block and the bottom of the guide cylinder. The upper end of the guide rod is fixedly installed with a fixed rod. The guide cylinder and the movable block are not completely sealed.

[0011] The inner wall of the guide cylinder is provided with a limiting groove, and two sets of teeth are fixedly provided on both sides of the limiting groove. The teeth have an outer right trapezoidal cross-section. The side wall of the movable block is equipped with a limiting group that works with the teeth.

[0012] The limiting group includes a slider and a second spring. The side wall of the movable block is provided with a storage groove for use with the limiting group. The slider is slidably connected to the storage groove.

[0013] In practical applications, when the operator controls the drive assembly to rotate the movable column, the movable column drives the fixed rod to rotate, the fixed rod drives the guide rod to rotate, the guide rod drives the movable block to rotate, and the movable block causes the limit group to shift, thus allowing the slider to enter the upper end of one set of teeth. When the movable column descends, it drives the fixed rod to descend, the fixed rod drives the guide rod to descend, and the guide rod drives the movable block to descend. The slider then enters the tooth group, preventing the movable block from rising, and consequently, preventing the movable column from rising. This avoids accidents caused by the spring device suddenly raising the movable column when breaking through the flange blank. After processing is completed, the drive assembly drives the movable column to rotate, causing the slider to disengage from the teeth. The first spring then pushes the movable block to rise, allowing the movable column to return to its original position along with the stepped column. Subsequently, the drive assembly continues to rotate, moving the fixed rod to the top of the support rod, allowing the next flange to be processed.

[0014] A damping rubber ring can be installed between the guide rod and the guide cylinder to slow down the upward speed of the guide rod.

[0015] Furthermore, the drive assembly includes a rack and an electric telescopic rod. The electric telescopic rod is fixedly installed inside the housing. The outer wall of the movable column is provided with a toothed groove for use with the rack. The electric telescopic rod can be of the Ti MOTION JP4 model. The rack is slidably connected to one of the support columns.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention relates to a forging blank device for flange processing. Since the worktable is detachable and the stepped columns are replaceable, when different models of flanges need to be manufactured, the operator can first disassemble the worktable, then take out the stepped columns, and then replace them with different stepped columns, thereby increasing the ability to manufacture different models of products and improving the practicality of the device.

[0018] This flange forging device features a fixed rod positioned directly above a support rod during hammering. The support rod supports the fixed rod, which in turn supports a movable column, which in turn supports a stepped column, preventing the stepped column from falling. This ensures the upper surface of the stepped column is at the same height as the upper surface of the worktable. When drilling is required, the operator controls the drive assembly to rotate the movable column, which in turn rotates the fixed rod, causing it to detach from the upper end of the support rod. The operator then places the die core in the center of the mold and uses hydraulic impact to push the die core to the center of the flange blank. After hammering for a certain period, the die core enters the circular hole in the center of the worktable, completing the initial processing of the flange blank. Because the stepped column in the middle of this device can be raised and lowered, the operator can directly use the die core without lifting the mold, reducing workload. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Reference Figure 1-6A forging blank device for flange processing includes a worktable 1 and a housing 6. The worktable 1 is fixedly installed on the upper end of the housing 6 by bolts. The bolt installation position can be adjusted as needed. A mold 2 for manufacturing flanges is placed on the upper end of the worktable 1. A support assembly 5 is installed inside the housing 6. An elastic device 4 is installed in the middle of the support assembly 5. An auxiliary assembly 3 for cooperating with the mold 2 is installed on the upper end of the elastic device 4.

[0029] Auxiliary component 3 includes a movable column 301, with a stepped column 304 detachably mounted on the upper end of the movable column 301. The stepped column 304 can be slidably connected, and will not detach from the movable column 301 during the upward movement of the stepped column 304 during the striking process. A through hole for use with the stepped column 304 is opened in the middle of the worktable 1, and a round hole for use with the movable column 301 is opened in the middle of the worktable 1. A fixing rod 302 is fixedly installed at the lower end of the movable column 301, and a drive component 303 is provided on one side of the movable column 301. This device only processes small flanges, and the size of this device can be adjusted according to actual needs.

[0030] Since the workbench 1 is detachable and the stepped column 304 is replaceable, when different models of flanges need to be manufactured, the workers can first disassemble the workbench 1, then take out the stepped column 304, and then replace it with different stepped columns 304, thereby increasing the ability to manufacture different models of products and improving the practicality of the device.

[0031] Furthermore, refer to Figure 1 and Figure 2 The support component 5 includes two support columns 501 fixedly installed inside the box 6. A support plate 502 is fixedly installed in the middle of the support column 501. A support rod 503 is fixedly installed at the upper end of the support plate 502 to cooperate with the fixing rod 302. The number and shape of the support columns 501 can be increased as needed. The support columns 501 are mainly used to support the top of the box 6 and prevent the top of the box 6 from deforming. The box 6 is a thickened metal box.

[0032] During the hammering process, the fixed rod 302 is located directly above the support rod 503, thus the support rod 503 supports the fixed rod 302, the fixed rod 302 supports the movable column 301, and the movable column 301 supports the stepped column 304, preventing the stepped column 304 from falling. Therefore, the upper surface of the stepped column 304 is at the same height as the upper surface of the worktable 1. When a hole needs to be drilled, the operator controls the drive assembly 303 to rotate the movable column 301, which in turn rotates the fixed rod 302, causing the fixed rod 302 to detach from the upper end of the support rod 503. At this point, the operator places the mold core in the middle of the mold 2 and uses hydraulic impact to push the mold core to the middle of the flange blank. After hammering for a certain period, the mold core will enter the round hole in the middle of the worktable 1, thus completing the initial processing of the flange blank. Because the stepped column 304 in the middle of this device can be raised and lowered, the operator does not need to lift the mold 2 to directly use the mold core, reducing the workload of the operator.

[0033] Furthermore, refer to Figure 3-6 The elastic device 4 includes a guide cylinder 401 fixedly installed in the middle of the support plate 502. A movable block 403 is slidably and rotatably installed inside the guide cylinder 401. A guide rod 402 is fixedly installed at the upper end of the movable block 403. A first spring 404 is placed between the lower end of the movable block 403 and the bottom of the guide cylinder 401. The upper end of the guide rod 402 is fixedly installed with the fixed rod 302. The guide cylinder 401 and the movable block 403 are not completely sealed.

[0034] The inner wall of the guide cylinder 401 is provided with a limiting groove 4011, and two sets of teeth 4012 are fixedly provided on both sides of the limiting groove 4011. The teeth 4012 have a right-angled trapezoidal shape in cross section. The side wall of the movable block 403 is equipped with a limiting group 405 that is used in conjunction with the teeth 4012.

[0035] The limiting assembly 405 includes a slider 4052 and a second spring 4051. The side wall of the movable block 403 is provided with a storage groove for use with the limiting assembly 405. The slider 4052 is slidably connected to the storage groove.

[0036] In practical applications, when the operator controls the drive component 303 to rotate the movable column 301, the movable column 301 drives the fixed rod 302 to rotate, the fixed rod 302 drives the guide rod 402 to rotate, the guide rod 402 drives the movable block 403 to rotate, and the movable block 403 causes the limit group 405 to shift, thereby causing the slider 4052 to enter the upper end of one set of teeth 4012. When the movable column 301 descends, it drives the fixed rod 302 to descend, which in turn drives the guide rod 402 to descend, which in turn drives the movable block 403 to descend, and the slider 4052... It will enter the tooth assembly, so the movable block 403 cannot rise, and thus the movable column 301 cannot rise. This avoids the accident caused by the spring device 4 suddenly raising the movable column 301 when breaking through the flange blank. At the same time, after the processing is completed, the drive assembly 303 drives the movable column 301 to rotate, so that the slider 4052 disengages from the tooth 4012. Then the first spring 404 pushes the movable block 403 to rise, so that the movable column 301 drives the stepped column 304 to return to its original position. Then the drive assembly 303 continues to rotate, so that the fixed rod 302 moves to the top of the support rod 503, so that the next flange can be processed.

[0037] A damping rubber ring can be installed between the guide rod 402 and the guide cylinder 401 to slow down the upward speed of the guide rod 402.

[0038] Furthermore, refer to Figure 3 The drive assembly 303 includes a rack 3031 and an electric telescopic rod 3032. The electric telescopic rod 3032 is fixedly installed inside the housing 6. The outer wall of the movable column 301 is provided with a toothed groove 3011 that is used in conjunction with the rack 3031. The electric telescopic rod 3032 can be of the TiMOTION JP4 type. The rack 3031 is slidably connected to one of the support columns 501.

[0039] Working principle: During the hammering process, the fixed rod 302 is located at the top of the support rod 503, thus the support rod 503 supports the fixed rod 302, the fixed rod 302 supports the movable column 301, and the movable column 301 supports the stepped column 304, preventing the stepped column 304 from falling. Therefore, the upper surface of the stepped column 304 is at the same height as the upper surface of the worktable 1. When a hole needs to be drilled, the operator controls the drive component 303 to rotate the movable column 301, which in turn rotates the fixed rod 302. This causes the fixed rod 302 to detach from the top of the support rod 503. At this point, the operator places the mold core in the middle of the mold 2 and uses hydraulic impact to push the mold core to the middle of the flange blank. After hammering for a certain period, the mold core enters the round hole in the middle of the worktable 1, thus completing the initial processing of the flange blank. Because the stepped column 304 in the middle of this device can be raised and lowered, the operator does not need to lift the mold 2 to directly use the mold core, reducing the workload of the operator.

[0040] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
