DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0039] like Figure 1 As shown, a flange stamping process according to an embodiment of the present invention has the following specific steps:

[0040] S1: Use a laser cutting machine or a cutting machine to cut out a ring-shaped iron plate blank of appropriate size from the raw iron plate;

[0041] S2: Using a stamping machine to stamp the iron plate blank, so that the iron plate blank is formed into a predetermined flange plate shape, and at the same time, a flange hole is punched out on the iron plate blank;

[0042] S3: Weld the flange body to the side wall of the plate, then perform shot blasting on the surface of the flange plate to clean the oxides and impurities on the flange surface and eliminate the welding stress between the flange body and the plate;

[0043] S4: Polish the flange to increase the smoothness of the flange surface. After polishing is completed, the flange can be packaged to complete the flange processing.

[0044] like Figure 2 As shown, the specific working steps of the stamping equipment in S1 are as follows:

[0045] S11: Control the stepper motor so that the stepper motor drives the rotating block 9 to rotate, and the punching slot 11 faces the position of the first punching block 5, and then the annular iron plate blank is placed at the top position of the punching slot 11 through the loading assembly;

[0046] S12: Start the electric push cylinder, so that the push rod 2 pushes the punching plate 3 to move downward, and the first punching block 5 cooperates with the punching groove 11 to punch the annular iron plate blank, and at the same time, the second punching block 6 cuts a flange hole on the iron plate blank;

[0047] S13: Control the stepper motor to drive the rotating block 9 to rotate 180 degrees, so that the stamping groove 11 containing the flange plate is toward the bottom position of the rotating block 9, and then release the flange plate so that the flange plate falls onto the top of the swing block 13;

[0048] S14: The position of the flange plate is monitored by a laser sensor to determine the rotation direction of the servo motor that drives the swing block 13 to rotate, and then the flange plate is dumped into the first collecting bin 15 to collect the flange plate.

[0049] like Figures 3 to 5As shown, a flange stamping device is suitable for any of the above-mentioned flange stamping processes, including a stamping machine body 1; a push rod 2 is slidably connected to the inside of the stamping machine body 1; the sliding of the push rod 2 is driven by a pneumatic cylinder or a hydraulic cylinder; the bottom end of the push rod 2 is fixedly connected to a stamping plate 3; the top of the stamping plate 3 is fixedly connected to a positioning rod 4; the positioning rod 4 is slidably connected to the inside of the stamping machine body 1; the bottom of the stamping plate 3 is fixedly connected to a first stamping block 5; the bottom of the first stamping block 5 is fixedly connected to a plurality of second stamping blocks 6, and the second stamping blocks 6 are regularly arranged in a circular array at the bottom of the first stamping block 5; the stamping machine body 1 is fixedly connected with a processing table 7 by fixing bolts 8; the processing table 7 is set at the position corresponding to the stamping plate 3; the internal rotation of the stamping machine body 1 is connected with a rotating block 9; two stamping grooves 11 are provided on the outer wall of the rotating block 9; the stamping grooves 11 are symmetrically arranged on the outer wall of the rotating block 9; a stepper motor is fixedly connected to the outer wall of the stamping machine body 1; the output end of the stepper motor is fixedly connected to the first rotating shaft 10; the end of the first rotating shaft 10 is fixedly connected to the side wall of the rotating block 9; during operation, when it is necessary to stamp the flange plate, it is first necessary to control the stepper motor to drive the rotating block 9 to rotate, so that the stamping The pressing groove 11 is facing the position corresponding to the first punching block 5, and then the annular iron plate blank can be placed on the top of the punching groove 11 through the loading equipment, and then the electric push cylinder can be driven to drive the push rod 2 to push downward, and then the iron plate blank is punched out of shape through the cooperation of the first punching block 5 and the punching groove 11, and at the same time, a flange hole is punched out on the iron plate blank through the punching of the second punching block 6. The length of the second punching block 6 can be set to adapt to the thickness of the iron plate blank. After the stamping is completed, the stepper motor can be driven to drive the rotating block 9 to rotate through the first rotating shaft 10, so that the rotating block 9 rotates and another punching groove 11 is facing the position corresponding to the first punching block 5. At the same time, multiple second punching blocks 6 are used to punch the flange plate at the same time, which can effectively avoid the situation where the rotating iron plate blank is easily rotated at different angles, resulting in different spacings between the flange holes. At the same time, the first rotating shaft 10 is driven to rotate by a stepper motor, and then the rotating block 9 is driven to rotate. The flange plate can be unloaded while stamping, which reduces the unloading steps and makes the flange plate production efficiency higher. To ensure the normal rotation of the rotating block 9, the diameter of the rotating groove opened inside the stamping machine body 1 and the processing table 7 must be adapted to the shape of the rotating block 9 and the diagonal length, so that the rotating block 9 can rotate normally inside the rotating groove.

[0050] like Figures 5 and 6As shown, a servo motor is fixedly connected to the side wall of the stamping machine body 1; the output end of the servo motor is fixedly connected to a second rotating shaft 12; the end of the second rotating shaft 12 is fixedly connected to a swing block 13; the swing block 13 is rotatably connected to the inside of the stamping machine body 1; the swing block 13 is set at a position corresponding to the bottom of the rotating block 9; a plurality of detection rods 14 are fixedly connected to the top of the swing block 13; the detection rods 14 are set at positions corresponding to the second stamping block 6; the top of the detection rod 14 is set in a cone shape; the inside of the stamping machine body 1 is slidably connected to two first collecting drawers 15; the two first collecting drawers The drawers 15 are arranged at positions on both sides of the rotation direction of the corresponding swing block 13; the interior of the stamping machine body 1 is slidably connected to two second collecting drawers 16; the second collecting drawer 16 is arranged at a position corresponding to the bottom of the first collecting drawer 15; the bottom of the first collecting drawer 15 and the interior of the stamping machine body 1 are provided with filter holes, and the filter holes are provided at positions corresponding to the second collecting drawers 16; a laser sensor is installed inside the stamping machine body 1; during operation, when the rotating block 9 rotates, driving the disc of the processed flange to rotate to the position corresponding to the bottom of the rotating block 9, the disc will fall vertically and then fall on the swing block 13. When the disc falls on the top of the swing block 13, if the detection rod 14 passes through the flange hole of the disc, it can be determined that the disc is qualified. If the flange hole of the disc is blocked by the detection rod 14 and does not contact the top of the swing block 13, it can be determined as a defective product. The laser sensor is set at the position corresponding to the top surface of the swing block 13. Within a certain period of time, after the laser sensor detects that an object has fallen on the top of the swing block 13, the servo motor will drive the swing block 13 to deflect to the first collecting drawer 15 on one side through the second rotating shaft 12, and pour the disc on the top of the swing block 13 into one of the first collecting drawers 15. If no object is detected falling into the top of the swing block 13, the servo motor will drive the swing block 13 to deflect to the first collecting drawer 15 on the other side through the second rotating shaft 12, so that the collection of qualified and defective products on the plate can be more convenient. At the same time, by providing filter holes in the first collecting drawer 15 and the inside of the stamping machine body 1, the punched round iron pieces can fall into the inside of the second collecting drawer 16, making it more convenient to collect the punched scraps. When the empty slot corresponding to the swing block 13 is provided in the inside of the stamping machine body 1, it is necessary to pay attention to not blocking the rotation of the swing block 13, and at the same time not blocking the round patches from falling.

[0051] like Figure 5As shown, fixed magnetic blocks 17 are fixedly connected to the side walls of the first collecting drawer 15 and the second collecting drawer 16; magnetic blocks are fixedly connected to the inside of the stamping machine body 1; the fixed magnetic blocks 17 on the side walls of the first collecting drawer 15 or the second collecting drawer 16 and the magnetic blocks on the side walls of the stamping machine body 1 are grouped in pairs, and are all arranged to attract each other; during operation, when the first collecting drawer 15 and the second collecting drawer 16 are placed inside the stamping machine body 1, the fixed magnetic blocks 17 are adsorbed and fixed to the magnetic blocks, so that the first collecting drawer 15 and the second collecting drawer 16 can be placed more stably inside the stamping machine body 1.

[0052] like Figure 5 and Figure 7 As shown, the interior of the rotating block 9 is slidably connected to a sliding block 18; the sliding block 18 is arranged at a position corresponding to the interior of the stamping groove 11; a spring is fixed between the sliding block 18 and the side wall of the rotating block 9; the top of the sliding block 18 is fixedly connected to an adsorption magnetic block 19; the adsorption magnetic block 19 and the bottom surface of the stamping groove 11 are in the same plane; a pushing inclined groove 20 is provided inside the rotating block 9; the interior of the stamping machine body 1 is slidably connected to a pushing inclined block 21; the sliding of the pushing inclined block 21 is driven by an electric push rod; the pushing inclined block 21 is arranged at a position corresponding to the pushing inclined groove 20; a through hole is provided inside the rotating block 9, which is provided inside the rotating block 9 between the pushing inclined block 21 and the pushing inclined groove 20; the sliding block 18 An anti-slip block 22 is fixed to the side wall; the anti-slip block 22 is slidably connected to the inside of the rotating block 9; during work, during the stamping process of the disc plate, the disc plate is adsorbed by the adsorption magnetic block 19, which can make the disc plate better maintain stability during the processing process. When the rotating block 9 drives the disc plate to rotate so that the disc plate is toward the position of the rotating block 9, the electric push rod can be driven so that the electric push rod pushes the pushing inclined block 21, and then the pushing inclined block 21 cooperates with the pushing inclined groove 20 to push the sliding block 18, so that the sliding block 18 is retracted into the inside of the rotating block 9, thereby making the adsorption magnetic block 19 disengage from the disc plate. When the adsorption magnetic block 19 is disengaged from the disc plate, the disc plate can fall vertically, so that the disc plate can fall on the top of the swing block 13 more accurately.

[0053] like Figure 8As shown, the interior of the fixing bolt 8 is slidably connected to a sliding plate 23; the bottom of the sliding plate 23 is fixedly connected to a connecting rod 24; the end of the connecting rod 24 is fixedly connected to a contact block 25; a spring is fixed between the top of the sliding plate 23 and the inner side wall of the fixing bolt 8; during operation, when the processing table 7 and the stamping machine body 1 are fixed by the fixing bolt 8, in the process of screwing the fixing bolt 8 into the threaded hole, the contact block 25 will first contact the bottom of the threaded hole, and then continue to screw into the fixing bolt 8, the contact block 25 is blocked and will squeeze the sliding plate 23 through the connecting rod 24, so that the sliding plate 23 squeezes the spring, and the sliding plate 23 is pushed by the elastic force of the spring, which can make the friction between the thread on the surface of the fixing bolt 8 and the thread inside the threaded hole greater, so that the fixing bolt 8 can better fix the processing table 7.

[0054] like Figure 6 As shown, a group of positioning blocks 26 are fixedly connected to the side walls of the rotating block 9 and the swinging block 13; the two groups of positioning blocks 26 are respectively arranged at symmetrical positions of the first rotating shaft 10 and the second rotating shaft 12; during operation, when the first rotating shaft 10 and the second rotating shaft 12 drive the rotating block 9 and the swinging block 13 to rotate, by fixing the positioning blocks 26 on the side walls of the rotating block 9 and the swinging block 13, the positioning blocks 26 can be driven to rotate inside the stamping machine body 1 when the rotating block 9 and the swinging block 13 rotate, thereby making the rotating block 9 and the swinging block 13 more stable during the rotation process.

[0055] like Figure 6 As shown, a plurality of balls 27 are provided between the positioning block 26 and the stamping machine body 1; the side walls of the balls 27 are in contact with the side walls of the stamping machine body 1 and the positioning block 26; during operation, when the positioning block 26 rotates inside the stamping machine body 1, the sliding friction between the stamping machine body 1 and the positioning block 26 can be converted into rolling friction through the rolling of the balls 27, thereby making the friction between the stamping machine body 1 and the positioning block 26 smaller, and reducing the wear between the stamping machine body 1 and the positioning block 26.

[0056] like Figure 5 and Figure 7 As shown, a scraper 28 is fixedly connected to the side wall of the stamping machine body 1; the scraper 28 is arranged at the position corresponding to the adsorption magnetic block 19; during operation, in the process of rotation of the rotating block 9, when the disc inside the stamping groove 11 falls, the scraps remaining after the disc is stamped may be adsorbed and remain on the surface of the adsorption magnetic block 19. By arranging deformable scrapers 28 made of rubber material inside the stamping machine body 1, the scraper 28 can be extended into the interior of the stamping groove 11 when the stamping groove 11 passes through the scraper 28, and the scraps adsorbed on the surface of the adsorption magnetic block 19 are scraped and pushed off, effectively avoiding the scraps remaining on the surface of the adsorption magnetic block 19, which is easy to affect the subsequent processing.

[0057] During operation, when it is necessary to stamp the flange plate, first it is necessary to control the stepper motor to drive the rotating block 9 to rotate so that the stamping groove 11 faces the position corresponding to the first stamping block 5, and then the annular iron plate blank can be placed on the top of the stamping groove 11 through the feeding equipment, and then the electric push cylinder can be driven to drive the push rod 2 to push downward, and then the iron plate blank is punched out of shape through the cooperation of the first stamping block 5 and the stamping groove 11, and at the same time, the flange hole is punched out on the iron plate blank through the stamping of the second stamping block 6. The length of the second stamping block 6 can be set to adapt to the thickness of the iron plate blank. After the stamping is completed, the stepper motor can be driven to drive the rotating block 9 to rotate through the first rotating shaft 10, so that the rotating block 9 Rotate and point the other punching groove 11 toward the position corresponding to the first punching block 5. The flange plate is punched simultaneously by multiple second punching blocks 6, which can effectively avoid the situation where the rotating iron plate blank is easily rotated at different angles, resulting in different spacings between flange holes. At the same time, the first rotating shaft 10 is driven to rotate by a stepper motor, and then the rotating block 9 is driven to rotate. The flange plate can be unloaded while stamping, reducing the unloading steps and making the flange plate production efficiency higher. To ensure the normal rotation of the rotating block 9, the diameter of the rotating groove opened inside the stamping machine body 1 and the processing table 7 must be adapted to the shape of the rotating block 9, so that the rotating block 9 can rotate normally inside the rotating groove.

[0058] When the rotating block 9 rotates, driving the disc of the processed flange to rotate to the position corresponding to the bottom of the rotating block 9, the disc will fall vertically and then fall on the position of the top of the swing block 13. When the disc falls on the top of the swing block 13, if the detection rod 14 passes through the flange hole of the disc, it can be determined that the disc is qualified. If the flange hole of the disc is blocked by the detection rod 14 and does not contact the top of the swing block 13, it can be determined as a defective product. The laser sensor is set at the position corresponding to the top surface of the swing block 13. Within a certain period of time, after the laser sensor detects that an object has fallen into the top of the swing block 13, the servo motor will drive the swing block 13 to deviate to the first collecting drawer 15 on one side through the second rotating shaft 12. Turn, pour the disc on the top of the swing block 13 into the inside of one of the first collecting drawers 15. If no object is detected falling into the top of the swing block 13, the servo motor will drive the swing block 13 to deflect to the first collecting drawer 15 on the other side through the second rotating shaft 12, so that the collection of qualified and defective discs can be more convenient. At the same time, by opening filter holes in the first collecting drawer 15 and the inside of the stamping machine body 1, the punched round iron sheets can fall into the inside of the second collecting drawer 16, making it more convenient to collect the punched scraps. When opening an empty slot corresponding to the swing block 13 in the stamping machine body 1, it is necessary to pay attention to not blocking the rotation of the swing block 13, and at the same time not blocking the round patches from falling.

[0059] When the first collecting drawer 15 and the second collecting drawer 16 are placed inside the stamping machine body 1 , the first collecting drawer 15 and the second collecting drawer 16 are more stable when placed inside the stamping machine body 1 through the adsorption and fixation of the fixing magnetic block 17 and the magnetic block.

[0060] During the stamping process of the disc plate, the disc plate is adsorbed by the adsorption magnetic block 19, which can make the disc plate more stable during the processing process. When the rotating block 9 drives the disc plate to rotate so that the disc plate is toward the position of the rotating block 9, the electric push rod can be driven so that the electric push rod pushes the pushing inclined block 21, and then the pushing inclined block 21 cooperates with the pushing inclined groove 20 to push the sliding block 18, so that the sliding block 18 is retracted into the interior of the rotating block 9, thereby separating the adsorption magnetic block 19 from the disc plate. When the adsorption magnetic block 19 is separated from the disc plate, the disc plate can fall vertically, so that the disc plate can fall on the top of the swing block 13 more accurately.

[0061] When the processing table 7 and the stamping machine body 1 are fixed by the fixing bolt 8, during the process of the fixing bolt 8 being screwed into the threaded hole, the contact block 25 will first contact the bottom of the threaded hole, and then when the fixing bolt 8 continues to be screwed in, the contact block 25 is blocked and will squeeze the sliding plate 23 through the connecting rod 24, so that the sliding plate 23 squeezes the spring, and the sliding plate 23 is pushed by the elastic force of the spring, which can make the friction between the thread on the surface of the fixing bolt 8 and the thread inside the threaded hole greater, so that the fixing bolt 8 can better fix the processing table 7.

[0062] When the first rotating shaft 10 and the second rotating shaft 12 drive the rotating block 9 and the swing block 13 to rotate, by fixing the positioning block 26 on the side walls of the rotating block 9 and the swing block 13, the positioning block 26 can be driven to rotate inside the stamping machine body 1 when the rotating block 9 and the swing block 13 rotate, thereby making the rotating block 9 and the swing block 13 more stable during the rotation process.

[0063] When the positioning block 26 rotates inside the punching machine body 1, the sliding friction between the punching machine body 1 and the positioning block 26 can be converted into rolling friction through the rolling of the ball 27, thereby reducing the friction between the punching machine body 1 and the positioning block 26 and reducing the wear between the punching machine body 1 and the positioning block 26.

[0064] During the rotation of the rotating block 9, when the disc inside the stamping groove 11 falls down, the scraps remaining after stamping the disc may be adsorbed and remain on the surface of the adsorption magnetic block 19. By arranging a deformable scraper 28 made of rubber material inside the stamping machine body 1, the scraper 28 can be extended into the interior of the stamping groove 11 when the stamping groove 11 passes through the scraper 28, and the scraps adsorbed on the surface of the adsorption magnetic block 19 are scraped and pushed off, effectively avoiding the scraps remaining on the surface of the adsorption magnetic block 19, which may easily affect subsequent processing.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
