Description

Technical Field

[0001] The present invention relates to the technical field of flange forging, and in particular to automated forging equipment for mechanical flanges. Background Art

[0002] Flanges are parts that connect shafts to each other and are used to connect pipe ends. They are also used at the inlet and outlet of equipment to connect two devices. Flanges are used in pairs, with a sealing gasket added between the two flanges and then fastened with bolts. The existing flange production process is mainly divided into two processes: forging and casting. The forging process generally consists of blanking, heating, forging, and cooling after forging. Special forging equipment is required in the forging process.

[0003] The existing flange forging equipment has the following technical defects when in use. First, when using the die, it currently relies on experienced masters to manually clamp and place it on the workpiece, which easily leads to errors in the workpiece produced, and is time-consuming and labor-intensive with a low degree of automation; second, during the forging process, adhesion occurs between the die and the workpiece. Powdered release agent is often applied to the inner surface of the die before the workpiece is formed, but the current application method is manual, inefficient, and the application is not uniform enough, shortening the service life of the die; third, after the workpiece is forged, it will fit tightly in the forging die and cannot be directly removed manually. Removal is time-consuming and labor-intensive, resulting in low work efficiency.

[0004] To sum up, considering that the existing equipment cannot meet the work requirements, we propose an automated forging equipment for mechanical flanges. Summary of the Invention

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0042] like Figure 1-9As shown, this embodiment provides an automated forging equipment for mechanical flanges, including a workbench 1, with legs welded at the four corners of the bottom of the workbench 1 to play a supporting role. The upper side of the workbench 1 is connected to a top seat 3 through two groups of support arms 2, and a working cylinder 4 is vertically installed in the middle of the top seat 3. The upper end of the working cylinder 4 is connected to the compression cylinder 6 through a vent pipe 5. The compression cylinder 6 is vertically installed on the upper end surface of the top seat 3, and the compression cylinder 6 passes through the top seat 3 and is downwardly installed with a crank connecting rod driver 13. When the crank connecting rod driver 13 is working, it compresses or inhales the gas in the compression cylinder 6. The interior of the working cylinder 4 is movably provided with a telescopic rod 11 that passes downward through the top seat 3, and the lower end of the telescopic rod 11 is welded with an air hammer 12. The air hammer 12 acts on the forging die 20 or the die part 62.

[0043] Furthermore, a forging die 20 is installed at the middle position of the upper end surface of the workbench 1, and a workpiece for the air hammer 12 to act on is placed in the forging die 20. Figure 1 and 2 shown.

[0044] Specifically, the upper end surface of the forging die 20 is provided with a pressure-bearing surface 21, which plays a force-bearing role. A forging groove 22 for placing a workpiece is opened in the middle position of the upper end surface of the forging die 20, and an inner groove 23 is opened in the middle position of the forging groove 22. The lower end of the forging die 20 extends into the interior of the workbench 1 and is provided with a material pipe 26. The inner groove 23 and the material pipe 26 are connected, as shown in FIG. Figure 3 and 5 shown.

[0045] Furthermore, the lower end of the material pipe 26 is obliquely connected to a material guide pipe 27 to guide the material. A mixing seat 28 is installed at one end of the material guide pipe 27 away from the material pipe 26. Figure 3 and 4 shown.

[0046] Among them, the mixing seat 28 is provided with an airflow mixing chamber inside. The end of the mixing seat 28 away from the guide pipe 27 is connected to the pressure tank 30 through the pulse tube 29. The pulse tube 29 is equipped with an electromagnetic pulse valve, which is intermittently opened and closed. The pressure tank 30 is set through the outer surface of the workbench 1. The airflow mixing chamber is connected to the guide pipe 27 and the pulse tube 29 respectively. Figure 3 and 4 shown.

[0047] The bottom of the mixing seat 28 is provided with a sealed discharge cover 31 with a sealing ring around it. After the sealed discharge cover 31 is opened, the material is dropped from the bottom surface of the workbench 1. Figure 4 shown.

[0048] Furthermore, a wheel housing 32 is installed on the upper end surface of the mixing seat 28, and a material dividing wheel 33 is fitted inside the wheel housing 32 to fully fit and prevent material leakage. Figure 3 and 6 shown.

[0049] In this embodiment, a roller 34 is splined in the middle of the dividing wheel 33. One end of the roller 34 is fixed to the inner wall of the wheel housing 32 through the first bearing seat 35, which plays a connecting and fixing role. The other end of the roller 34 is connected to the first servo motor 36 through a coupling. Two sets of quantitative wheel grooves 37 are symmetrically opened on the wheel surface of the dividing wheel 33 to play a quantitative role. Figure 6 shown.

[0050] In this embodiment, a feed port is provided at the top of the wheel housing 32, and the size and shape of the feed port match those of the metering wheel groove 37. The upper end of the feed port is connected to a storage hopper 38, and the storage hopper 38 is located inside the workbench 1. A feeding cover 39 is movably provided on the upper end surface of the storage hopper 38. A discharge port is provided at the bottom of the wheel housing 32, and the size and shape of the discharge port match those of the metering wheel groove 37, and the discharge port is connected to the airflow mixing chamber.

[0051] Furthermore, the upper end surface of the workbench 1 is symmetrically provided with two sets of limit grooves 60 located at the rear side of the forging die 20, which play the role of limit guide. A bidirectional screw drive structure 7 is installed on the limit groove 60. Figure 2 shown.

[0052] Furthermore, a discharge platform 61 is fixed between the two sets of limit grooves 60, and a die 62 is placed on the discharge platform 61 to act on the middle position of the workpiece. The bottom area of ​​the die 62 is larger than the area of ​​the upper end surface of the discharge platform 61. Figure 7 shown.

[0053] Specifically, the bidirectional screw drive structure 7 includes a bidirectional screw 71, a second bearing seat 72, a screw motor 73, a forward spiral pattern 74, a reverse spiral pattern 75 and a clamp 8, as shown in FIG. Figure 7 shown.

[0054] In this embodiment, the bidirectional screw rod 71 is horizontally arranged inside the workbench 1. One end of the bidirectional screw rod 71 is fixed to the inner wall of the workbench 1 through the second bearing seat 72, which plays a connecting and fixing role. The other end of the bidirectional screw rod 71 is connected to the screw motor 73 through a coupling. The bidirectional screw rod 71 is symmetrically distributed with forward spiral patterns 74 and reverse spiral patterns 75. A group of clamps 8 are installed at the positions of the forward spiral patterns 74 and the reverse spiral patterns 75.

[0055] Specifically, the clamp 8 includes a moving seat 81, a screw nut sleeve 82, a guide rod 83 and a clamping seat 84. Figure 8 shown.

[0056] In this embodiment, a screw nut sleeve 82 acting on the forward spiral pattern 74 or the reverse spiral pattern 75 is installed in the middle position inside the moving seat 81, and a nut with spiral motion is arranged inside the screw nut sleeve 82. A guide rod 83 is vertically welded to the upper end of the moving seat 81, and the guide rod 83 moves linearly in the limiting groove 60. A clamping seat 84 is fixed to the upper end of the guide rod 83.

[0057] Furthermore, the clamp 8 further includes a guide groove 85, a connecting block 86, a curved clamping piece 87, a hydraulic rod 88 and a hydraulic cylinder 89, as shown in FIG. Figure 8 and 9 shown.

[0058] In this embodiment, a guide groove 85 is provided on the upper end surface of the clamping seat 84, which serves to limit the movement of the connecting block 86. A connecting block 86 is movably arranged in the guide groove 85, and a curved clip 87 is welded to the outside of the guide groove 85 on the inner side of the connecting block 86. The two sets of curved clips 87 act symmetrically on the die 62, and the curved surface of the curved clip 87 is fully fitted with the outer surface of the die 62.

[0059] In this embodiment, a hydraulic rod 88 is horizontally welded to the end of the connecting block 86. The hydraulic rod 88 extends outward from the inside of the hydraulic cylinder 89. The hydraulic cylinder 89 is horizontally fixed inside the clamping seat 84. The hydraulic rod 88 drives the connecting block 86 to move to the position of the forging die 20.

[0060] Furthermore, the curved clip 87 acts on the lower outer side of the die 62. The die 62 is a frustum structure with a smaller top and a larger bottom, which facilitates die pressing of the workpiece.

[0061] When this embodiment is in use, the air hammer 12 is first lowered to the upper end of the forging die 20 and contacts the pressure-bearing surface 21 to form a seal. Then the first servo motor 36 is turned on, the roller 34 rotates and drives the dividing wheel 33 to rotate half a circle. During this process, the metering wheel groove 37 at the top of the dividing wheel 33 is filled with the release agent powder falling from the storage hopper 38, and then moves downward to the bottom of the dividing wheel 33, and the powder in the metering wheel groove 37 is discharged downward from the discharge port into the air flow mixing chamber. At the same time, the electromagnetic pulse valve is opened, and the air in the pressure tank 30 flows into the air flow mixing chamber through the pulse tube 29, blowing the falling release agent powder, and entering the guide pipe 27. After passing through the material pipe 26, it is sprayed into various areas of the forging die 20 (including the inner surface of the forging groove 22, the inner surface of the inner groove 23 and the lower end face of the air hammer 12), forming a uniform coverage on the surface.

[0062] The workpiece is then placed into the forging groove 22 of the forging die 20 near the middle position, and then the crank connecting rod driver 13 is started. The air in the compression cylinder 6 is squeezed into the working cylinder 4 through transmission, causing the telescopic rod 11 to move downward, and the air hammer 12 directly hammers and forges the workpiece, repeatedly (the position of the workpiece must be continuously adjusted during the hammering process) until the workpiece fits completely in the forging groove 22 and is flush with the pressure-bearing surface 21. At this time, the workpiece is shaped in the inner groove 23 to form a flange connection.

[0063] After that, the die 62 is placed on the unloading table 61, and the screw motor 73 is started to drive the bidirectional screw 71 to rotate, causing the clamps 8 at the positions of the positive spiral pattern 74 and the reverse spiral pattern 75 to move toward each other along the limit groove 60, respectively using the curved clamping piece 87 to contact the outer side of the die 62, together forming a clamping and centering calibration effect on the die 62, and then simultaneously starting the two groups of hydraulic cylinders 89, the hydraulic rod 88 extends outward, driving the connecting block 86 and the curved clamping piece 87 to move linearly, carrying the die 62 away from the unloading table 61, and moving to the middle area of ​​the workpiece (the die 62 and the center of the workpiece are aligned, that is, the longest stroke of the hydraulic rod 88 Position), then move the air hammer 12 downward again to hammer the die 62, so that the die 62 passes through the groove and partially enters the workpiece (in this process, the die 62 and the curved clip 87 will slide relative to each other). At this time, let the two sets of clamps 8 return to their positions on both sides, and the curved clip 87 is away from the die 62. Continue to use the air hammer 12 to hammer the die 62 until the die 62 passes through the entire workpiece. The waste material and the die 62 fall downward into the material pipe 26, slide along the material guide pipe 27, and enter the air flow mixing chamber of the mixing seat 28. Open the sealed unloading cover 31, and the waste material and the die 62 are discharged from the bottom surface of the workbench 1. Example 2

[0064] On the basis of the first embodiment, after the workpiece is forged, it will fit tightly in the forging die 20 and cannot be directly removed manually. It is time-consuming and laborious to remove it. In addition, during the powder spraying process, some release agent powder will adhere to the wall of the material pipe 26 and the inner groove 23, causing pollution after a long time. In order to solve the above technical problems, we have the following design, such as Figure 10-12 shown.

[0065] Specifically, a cam seat 40 is fixed just below the material pipe 26, and the cam seat 40 is fixed to the bottom of the workbench 1. A rotating shaft 46 is rotatably provided in the middle position of the inner portion of the cam seat 40. A cam 47 is sleeved on the rotating shaft 46. The cam 47 includes a cam portion 48. One end of the rotating shaft 46 is fixed to the inner wall of the cam seat 40 through a third bearing seat 49, which plays a role in connection and fixing. The other end of the rotating shaft 46 is connected to a second servo motor 50 through a coupling. The second servo motor 50 is arranged to pass through the outer surface of the cam seat 40, as shown in FIG. Figure 10 and 11 shown.

[0066] Among them, a wheel seat 51 is provided above the cam 47. The wheel seat 51 is located in the middle position inside the outer sleeve 41. The outer sleeve 41 and the cam seat 40 are fixed. A mounting groove 52 is provided on the lower end surface of the wheel seat 51. A contact wheel 53 is rotatably provided in the mounting groove 52 to contact the wheel surface of the cam 47 (part of the contact wheel 53 extends out of the mounting groove 52). A push rod 54 is vertically welded to the upper end of the wheel seat 51. Figure 12 shown.

[0067] Among them, an annular spacer 55 is fixed inside the outer sleeve 41, and a rod hole 56 for the push rod 54 to pass through is opened in the middle position of the annular spacer 55, which plays a limiting and guiding role. A spring 57 is fixed between the annular spacer 55 and the wheel seat 51 and is sleeved on the outside of the push rod 54 to ensure the contact force between the cam 47 and the contact wheel 53. Figure 12 shown.

[0068] The push rod 54 extends upward into the interior of the material pipe 26 , and a cleaning rubber sleeve 58 is installed on the upper end of the push rod 54 . The cleaning rubber sleeve 58 has deformation restoration capability and friction force.

[0069] Furthermore, a guide cylinder 42 is fixed to the upper end of the outer sleeve 41, which acts on the push rod 54 and plays a role of limiting guidance. Figure 10 shown.

[0070] When this embodiment is in use, after the forging and perforation is completed, the second servo motor 50 is started to drive the rotating shaft 46 to rotate one circle, thereby causing the cam 47 to make a circular motion. The cam portion 48 of the cam 47 exerts pressure on the contact wheel 53 during the upward movement, thereby causing the wheel seat 51 and the push rod 54 to move upward. The upper end of the push rod 54 enters the interior of the material pipe 26 from the bottom of the material pipe 26, and then enters the inner groove 23 of the forging die 20 upward, applying thrust to the lower end face of the workpiece, thereby pushing the entire workpiece out of the forging die 20. During the upward linear movement of the push rod 54, the cleaning rubber sleeve 58 contacts the wall of the material pipe 26 and the inner surface of the inner groove 23 in turn to scrape off the residual powder, and then the push rod 54 returns to its original position under the action of the spring 57.
