Description

Technical Field

[0001] The invention relates to the technical field of flange forging, in particular to a forging device for a high-strength metal flange. Background Art

[0002] Flanges are parts used to connect pipes or pipes to valves, and forged flanges are the products with the best mechanical properties among flange products. Forged flanges are generally forged from carbon steel, alloy steel or stainless steel in forging equipment. The forging process of large high-strength metal flanges mainly consists of the following steps: first, the blank is heated and placed on the forging table, then the blank is continuously rotated by manual or other equipment and the surface of the blank is hammered by a forging hammer so that the blank gradually becomes cylindrical, then the blank is placed in a cylindrical mold and hammered to flatten the blank and improve the roundness, then the cylindrical mold is inserted into the middle of the blank and the cylindrical mold is punched with a hydraulic hammer, then the ring-shaped blank is taken out of the mold and the edge is hammered with a hydraulic hammer to form a flange, then the size and roundness of the blank are adjusted by a ring rolling machine and then cooled, and then the required forged flange is formed after drilling.

[0003] During the forging process, the surface of the blank is gradually cooled down due to the contact with the air. At the same time, due to the different cooling degrees between the inside and the surface of the blank, the material with a lower temperature on the surface is easily affected by the mechanical impact force during the hammering process and falls off. If these detached debris are gathered in large quantities on the upper surface of the forging table, it will affect the placement accuracy of the blank and the mold. At the same time, it is easy to be re-mixed into the blank, which will destroy the stress balance in the blank and cause the mechanical properties of the blank to decrease. Therefore, these peeled debris need to be cleaned up in time during the forging process.

[0004] The patent publication number is CN117415272A, and the patent name is "A metal flange forging equipment and its use method". The patent provides a device for cleaning debris. Specifically, the flying debris is magnetically adsorbed by a magnetic chip cleaning device arranged around the blank processing area. However, this method has at least two disadvantages. First, the debris still has a high temperature while flying in the air just after being peeled off the blank. Therefore, the surface of the debris has almost no magnetism and is difficult to be magnetically adsorbed. Secondly, the blank processing area is surrounded by the magnetic chip cleaning device, which seriously occupies a large amount of working space and affects the processing operation of the blank. Therefore, it is of low practicality and difficult to meet production needs.

[0005] Therefore, we need a high-strength metal flange forging equipment to solve the problem of lack of rapid cleaning equipment for magnetic debris in the existing forging flange processing process, which can effectively improve the processing accuracy and quality of flange products in the forging process. Summary of the invention

DETAILED DESCRIPTION

[0039] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figures 1 to 14The present invention provides a high-strength metal flange forging device, including a machine base 1, a horizontal adjustment device 21, a collecting device 3, a matching speed increasing device 8 and a controller 17. A flange workpiece blank 12 is placed on the machine base 1 through a die 13, and a hydraulic hammer 16 is driven by a hydraulic push rod 15 on the machine base 1 to forge the flange workpiece blank 12. The die 13 has different models for use in different stages of forging. The specific forging process of the flange workpiece blank is as follows: first, the heated flange workpiece blank 12 is placed on the machine base 1, and the blank is continuously rotated and the hydraulic hammer 16 is used to forge the flange workpiece blank 12. The flange workpiece blank 12 is hammered repeatedly so that it is nearly cylindrical. The rotation of the flange workpiece blank 12 can be performed by the operator holding a corresponding clamp. After the flange workpiece blank 12 is hammered nearly cylindrical, the cylindrical mold 13 is manually placed vertically in the machine base 1, and then the flange workpiece blank 12 is inserted into the cylindrical mold 13. Then, the hydraulic hammer 16 is continued to hammer the flange workpiece blank 12, so that the flange workpiece blank 12 can fill the cylindrical mold 13. In this way, the flange workpiece blank 12 can be formed by using the cylindrical mold 13. The flange workpiece blank 12 is shaped into a cylindrical shape, and then another cylindrical mold 13 is inserted into the center of the cylindrical flange workpiece blank 12, and the cylindrical mold 13 is hammered by a hydraulic hammer 16, so that a through hole is punched in the center of the flange workpiece blank 12 by the cylindrical mold 13, and then the cylindrical mold 13 and the cylindrical mold 13 are inverted and a support base for supporting the cylindrical mold 13 is placed at the bottom of the cylindrical mold 13, and then the flange workpiece blank 12 is hammered from above by a hydraulic hammer 16 to make it fall off from the bottom of the cylindrical mold 13, and then the cylindrical mold 13 is removed. The die 13, the cylindrical die 13 and the base for supporting the cylindrical die 13 are arranged, and then the flange workpiece blank 12 is rearranged, and then the edge of the flange workpiece blank 12 is hammered by the hydraulic hammer 16 and the position of the flange workpiece blank 12 is manually adjusted during the hammering process to form a flange on the flange workpiece blank 12. At this time, the flange workpiece blank 12 formally completes the forging process and becomes a flange workpiece prototype. Subsequently, the ring rolling machine is used to further adjust the size and roundness of the flange workpiece prototype, and then the required flange workpiece can be formed after cooling and drilling processes.

[0041] See also Figure 1 and Figure 2 The horizontal adjustment device 21 includes a guide rail 212 fixedly installed at the front and rear ends of the machine base 1, and a screw motor 211 is fixedly installed at the end of the guide rail 212. The screw motor 211 drives the collecting platform 14 to move left and right along the guide rail 212 through a screw.

[0042] See also Figure 1 , Figure 3 , Figure 6 , Figure 7 and Fig.14 The collecting device 3 includes a bearing shaft 303 rotatably mounted on the left and right sides of the collecting platform 14, and at least four bar electromagnet units 302 for collecting magnetic debris are arranged in a circular array on the bearing shaft 303. The bar electromagnet unit 302 is powered by the power supply device 4. When the bar electromagnet unit 302 is powered by the power supply device 4, the bar electromagnet unit 302 can absorb the magnetic debris close to itself and located on the upper surface of the base 1.

[0043] See also Figure 1 , Figure 4 and Figure 8 The cooperating speed increasing device 8 includes a cooperating mounting seat 801 fixedly mounted on the collecting platform 14, and a first connecting wheel 802, a second connecting wheel 803 and a third connecting wheel 804 meshingly connected in sequence are mounted on the cooperating mounting seat 801 through bearings, a rack 213 is integrally formed on the guide rail 212, and the rack 213 is meshingly connected with the second cooperating wheel 805, the second cooperating wheel 805 is coaxially fixed with the third connecting wheel 804, and an end gear 301 meshingly mounted with the first connecting wheel 802 is coaxially mounted on the bearing shaft 303. When the screw motor 211 drives the collecting platform 14 to move left and right along the guide rail 212, the second cooperating wheel 805 will generate a relative rotation with the rack 213. The movement is carried out, so that the second matching wheel 805 is used to drive the third connecting wheel 804, the second connecting wheel 803 and the first connecting wheel 802 to rotate in turn, and then the first connecting wheel 802 is used to drive the end gear 301 to rotate, so that the end gear 301 is used to drive the bearing shaft 303 and the bar electromagnet unit 302 to rotate. At this time, the bar electromagnet unit 302 can be used to follow the movement of the collecting table 14 and adsorb the magnetic debris on the upper surface of the base 1, and the bar electromagnet unit 302 follows the rotation of the bearing shaft 303 to make the magnetic debris adsorbed more evenly, thereby avoiding the magnetic debris from gathering in the bottom area of ​​the bearing shaft 303 and affecting the adsorption effect.

[0044] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 , controller 17, the controller 17 is fixedly mounted on the machine base 1, and the controller 17 is electrically connected to the hydraulic push rod 15, the screw motor 211 and the power supply device 4.

[0045] See also Figure 3 , Figure 6 , Figure 7 , Fig.12 , Fig.13 and Fig.14The power supply device 4 includes a power supply connection seat 403 fixedly mounted on the collection table 14, and a pair of power supply rings 402 electrically connected to the controller 17 are installed on the power supply connection seat 403. The coil winding of each bar-shaped electromagnet unit 302 is rotatably mounted with the power supply contact 304 and the power supply ring 402 to realize power supply. Each power supply contact 304 has two mutually isolated contact points for respectively fitting the two power supply rings 402 and respectively connecting to the positive and negative poles of the coil winding of the bar-shaped electromagnet unit 302. In this way, only two power supply rings 402 are needed to be connected to the controller 17. 7 or the positive and negative poles of the external power supply device can realize the normal power supply to the coil winding on each bar-shaped electromagnet unit 302. The middle part of the collection platform 14 is hollow, and the power supply ring 402 is provided with an interruption end 401 that does not perform power supply operation on the side facing the collection platform 14. The collection platform 14 is provided with a scraping device 2 for scraping the magnetic debris on the bar-shaped electromagnet unit 302 into the collection platform 14. The scraping device 2 includes an intermediate bracket 202 fixed inside the collection platform 14, and a convenient magnetic debris falling into the collection platform 1 is provided in the middle of the intermediate bracket 202. 4, and the upper and lower ends of the intermediate bracket 202 are provided with scrapers 203 for scraping the magnetic debris on the bar-shaped electromagnet unit 302 so that the magnetic debris falls into the collecting table 14. When the power supply contact 304 rotates to the area corresponding to the interruption end 401, the power supply ring 402 will no longer supply power to the power supply contact 304, and the corresponding bar-shaped electromagnet unit 302 will lose its magnetism. Since the interruption end 401 is arranged on the side facing the collecting table 14, the bar-shaped electromagnet unit 302 will move to the area facing the collecting table 14. When the magnetism is lost in the corresponding area, the magnetic debris originally adsorbed on the bar electromagnet unit 302 by magnetic force will fall into the interior of the collecting table 14 under the combined action of gravity, the centrifugal force of the magnetic debris itself and the scraper 203, and the magnetic debris falling on the intermediate bracket 202 will also pass through the discharge hole 201 and enter the bottom of the internal cavity of the collecting table 14. At the same time, no matter whether the bearing shaft 303 is rotating forward or reverse at this time, the scraper 203 can scrape the magnetic debris on the surface of the bar electromagnet unit 302 which has lost its magnetism into the interior of the collecting table 14.

[0046] See also Figure 1 , Figure 8 , Fig. 9 , Fig.10 and Fig.11A pair of clamping arms 10 for clamping the flange workpiece blank 12 or the mold 13 is provided on the machine base 1, and the pair of clamping arms 10 are driven by a clamping drive device 6 to adjust the clamping position. A position adjustment device 5 for adjusting the height of the clamping arms 10 and the clamping drive device 6 is also provided between the clamping drive device 6 and the machine base 1. The clamping drive device 6 includes a support rod 607 fixed to the position adjustment device 5, and a guide rod 606 is fixedly installed on the support rod 607. The two clamping arms 10 are respectively slidably installed at both ends of the guide rod 606, and an intermediate rotating wheel 603 is rotatably installed in the middle of the guide rod 606. The upper and lower ends of the intermediate rotating wheel 603 are respectively provided with deviating from the center axis of the intermediate rotating wheel 603. The eccentric push rod 602 is hingedly installed with the clamping arm 10 through the hinge rod 11, the middle part of the guide rod 606 is fixedly installed with an adjusting motor 605, and the output end of the adjusting motor 605 drives the first worm 604, the middle part of the guide rod 606 is rotatably installed with a first worm wheel 601 that is meshed with the first worm 604 and the intermediate rotating wheel 603, and the adjusting motor 605 is electrically connected to the controller 17, the position adjustment device 5 includes a guide seat 504 fixed on the top of the machine base 1, and a moving seat 503 is slidably installed on the guide seat 504, a horizontal adjustment push rod 502 is fixedly installed on the guide seat 504, and the output end of the horizontal adjustment push rod 502 drives the moving seat 503 to move along the guide seat 504 The movable seat 503 is fixedly mounted with a height-adjusting push rod 501, and the output end of the height-adjusting push rod 501 is fixedly connected to the support rod 607 and is used to adjust the height of the clamping arm 10 and the clamping drive device 6. When the position of the mold 13 or the flange workpiece blank 12 needs to be adjusted, the movable seat 503 is first pushed along the guide seat 504 by the horizontal adjustment push rod 502, and then the height position of the clamping arm 10 is adjusted by the height-adjusting push rod 501, and then the intermediate rotating wheel 603 is driven to rotate by the adjustment motor 605. Since the position of the eccentric push rod 602 will change after the intermediate rotating wheel 603 rotates, the eccentric push rod 602 can be used to drive the articulated rod 11 to move. The hinge rod 11 is used to drive the clamping arm 10 to slide along the guide rod 606, and the distance between the two clamping arms 10 can be changed. When the two clamping arms 10 are close to each other, the mold 13 or the flange workpiece blank 12 can be clamped. When the two clamping arms 10 are away from each other, the two clamping arms 10 can release the mold 13 or the flange workpiece blank 12. At the same time, the distance that the clamping arm 10 moves along the guide rod 606 can be accurately changed by changing the rotation of the intermediate rotating wheel 603 to different angles, so that molds 13 or flange workpiece blanks 12 of different sizes can be clamped in a targeted manner. Therefore, it is suitable for processing flange workpieces of different sizes.Moreover, since a worm gear transmission mechanism consisting of a first worm 604 and a first worm wheel 601 is provided between the adjusting motor 605 and the intermediate rotating wheel 603, the first worm 604 and the first worm wheel 601 can also form a self-locking structure, so that during the process of clamping the mold 13 or the flange workpiece blank 12, even if the adjusting motor 605 stops working, the mold 13 or the flange workpiece blank 12 can still be effectively clamped tightly by the clamping arm 10, thereby avoiding the risk of the mold 13 or the flange workpiece blank 12 falling. After the mold 13 or the flange workpiece blank 12 is clamped by the clamping arm 10, the position of the mold 13 or the flange workpiece blank 12 can be changed by the height adjustment push rod 501 and the horizontal adjustment push rod 502, especially during the processing, the mold 13 or the flange workpiece blank 12 can be temporarily adjusted. The material 12 is lifted to a specified height position from the top surface of the machine base 1, so that the horizontal adjustment device 21 can drive the bar electromagnet unit 302 to quickly collect the magnetic debris on the machine base 1 during the processing, avoiding the accumulation of magnetic debris affecting the position placement accuracy of the mold 13 and the flange workpiece blank 12, and also avoiding the magnetic debris being re-mixed into the flange workpiece blank 12, causing the flange workpiece blank 12 to have an uneven texture and thus affect the material properties. In addition, it should be noted that if a cleaning layer composed of rubber or plastic materials is set on the surface of the bar electromagnet unit 302, the wavy texture or bristle structure set on the surface of the cleaning layer can be used to sweep the non-magnetic debris on the top of the machine base 1 into the collection table 14 for collection, thereby realizing the cleaning of the non-magnetic debris.

[0047] The forging equipment designed in this embodiment can use the hydraulic push rod 15 to drive the hydraulic hammer 16 to hammer the flange workpiece blank 12, and cooperate with different types of molds 13 to shape the flange workpiece blank 12, so as to realize the forging processing of the flange workpiece, and in the process of processing, the position adjustment device 5 and the clamping drive device 6 can be used to jointly drive the clamping arm 10 to adjust the position of the mold 13 or the flange workpiece blank 12, and in the process of changing the position of the mold 13 or the flange workpiece blank 12, the horizontal adjustment device 21 can be used to push the collecting table 14 to move left and right along the guide rail 212, so as to use the bar electromagnet unit 302 installed on the collecting table 14 to adjust the magnetic field on the base 1. The magnetic debris can be cleaned and collected, thereby avoiding the influence of these magnetic debris on the processing process. In addition, in the present scheme, the screw motor 211 not only drives the collection table 14 to move along the guide rail 212, but also can indirectly utilize the cooperation speed increasing device 8 to drive the bearing shaft 303 to rotate, and indirectly cooperate with the power supply device 4 to affect the process of the bar electromagnet unit 302 sending the magnetic debris to the collection table 14. Therefore, the function of the screw motor 211 is enriched, unnecessary control steps and control structures are reduced, and the equipment structure design is more sophisticated, which solves the problem of lack of rapid cleaning equipment for magnetic debris in the existing forging flange processing process, and can effectively improve the processing accuracy and the quality of flange products in the forging process.

When the collecting table 14 moves along the guide rail 212, the first matching wheel 706 will also move relative to the rack 213, so that the first matching wheel 706 drives the second bevel gear 705, the first bevel gear 703 and the first pulley 704 to move in sequence, and then the first pulley 704 drives the second pulley 222 to rotate through the transmission belt 701, and the second pulley 222 can drive the conveyor belt 221 to move through the conveying roller 223. When the magnetic debris enters the bottom of the inner cavity of the collecting table 14, the magnetic material will fall onto the conveyor belt 221, and then When the conveyor belt 221 starts to move, the magnetic debris on the conveyor belt 221 will move along the conveyor belt 221 toward the end of the collecting table 14. During the movement, the magnetic debris on the conveyor belt 221 will gradually enter the discharge port 18 along the edge of the inclined scraper blade 19 under the scraping of the inclined scraper blade 19. Then the magnetic debris enters the collecting box 20 through the discharge port 18 and is collected. This makes it convenient for subsequent maintenance personnel to clean the magnetic debris, further solves the problem of lack of rapid cleaning equipment for magnetic debris in the existing forging flange processing process, and can effectively improve the processing accuracy and the quality of flange products in the forging process.

[0049] Example 3: Please refer to Figure 1 , Figure 8 and Fig. 9On the basis of the second embodiment, a flipping device 9 for flipping the flange workpiece blank 12 or the mold 13 is provided on the clamping arm 10, and the flipping device 9 includes a flip shaft 901 rotatably mounted at the end of the clamping arm 10, and a flip clamping plate 902 for clamping the flange workpiece blank 12 or the mold 13 is fixedly mounted on the end of the flip shaft 901, an angle adjustment motor 904 electrically connected to the controller 17 is fixedly mounted on the clamping arm 10, and the output end of the angle adjustment motor 904 drives a second worm 905, a second worm wheel 906 meshing with the second worm wheel 905 is rotatably mounted on the clamping arm 10, and a sprocket 90 is coaxially mounted on the second worm wheel 906. 7, the sprocket 907 and the flip shaft 901 are connected by a transmission chain 903, and the angle adjustment motor 904 is used to adjust the inclination angle of the mold 13 or the flange workpiece blank 12, which is mainly used in two links of the processing process. The first link is when the flange workpiece blank 12 with a non-cylindrical shape is just placed on the machine base 1, it is necessary to gradually hammer the flange workpiece blank 12 into a cylindrical shape through the hydraulic hammer 16. At this time, it is necessary to adjust the placement angle of the flange workpiece blank 12 during the hammering process through the flip device 9, so that the surface of the flange workpiece blank 12 that needs to be hammered can correctly enter the bottom of the hydraulic hammer 16. The second link is when the flange workpiece blank 12 is punched When it needs to be discharged from the cylindrical mold 13, the mold 13 needs to be flipped by the flipping device 9. During the above flipping process, the angle adjustment motor 904 will drive the second worm 905 to rotate, and the second worm 905 will drive the second worm wheel 906 to rotate, and the second worm wheel 906 is coaxially fixed with the sprocket 907. Therefore, the sprocket 907 can drive the flip shaft 901 to rotate through the transmission chain 903, and the flip shaft 901 can drive the flip clamping plate 902 to rotate, so that the flip clamping plate 902 is used to drive the mold 13 or the flange workpiece blank 12 to rotate. At the same time, the worm gear transmission mechanism composed of the second worm 905 and the second worm wheel 906 also It has a self-locking function, which can effectively prevent the mold 13 or the flange workpiece blank 12 from driving the flip shaft 901 to rotate in the opposite direction, so that there is no need for the angle adjustment motor 904 to continue working after working to the specified rotation angle. During the above-mentioned flipping process, the mold 13 and the flange workpiece blank 12 can also be lifted to a specified height by the height adjustment push rod 501, so as to facilitate the bar electromagnet unit 302 to clean and collect the magnetic debris located on the machine base 1 from below the mold 13 or the flange workpiece blank 12, further solving the problem of lack of rapid cleaning equipment for magnetic debris in the existing forging flange processing process, and can effectively improve the processing accuracy and the quality of flange products during the forging process.

[0051] Step 1: First, input the size information of the flange workpiece blank 12 to be processed into the controller 17 and input the corresponding workflow, then correctly place the flange workpiece blank 12 on the machine base 1 and issue a forging instruction through the controller 17, then the hydraulic push rod 15 will push the hydraulic hammer 16 to hammer forge the flange workpiece blank 12, and at the same time, the clamping arm 10 will cooperate with the flipping device 9 under the drive of the position adjustment device 5 and the clamping drive device 6 to adjust the position of the flange workpiece blank 12 or the die 13 at different stages during the forging process;

[0052] Step 2: When the clamping arm 10 adjusts the position of the flange workpiece blank 12 or the mold 13, the height adjustment push rod 501 will lift the flange workpiece blank 12 or the mold 13 upward to a specified height and retain it for a specified time. At the same time, the horizontal adjustment device 21 will drive the bar-shaped electromagnet unit 302 to collect the magnetic debris above the machine base 1 and send it to the collection table 14;

[0053] Step 3: The magnetic debris entering the collecting table 14 will also be conveyed by the conveyor belt 221 to the collecting box 20 for centralized storage, so that the collecting box 20 can be replaced and cleaned manually during the maintenance of the forging equipment, thereby facilitating the maintenance process.
