Description

Technical Field

[0001] The invention belongs to the technical field of sealing ring processing, and in particular relates to a stamping forming method for a sealing ring belt of a high-pressure pneumatic angle seat valve seat. Background Art

[0002] A high-pressure pneumatic angle seat valve is a valve that uses a pneumatic actuator to drive the movement of the valve core to control the flow of the medium in the pipeline. The sealing ring is a key component in the angle seat valve. It is located between the valve seat and the valve core and plays a sealing role to prevent the medium from leaking from the gap between the valve seat and the valve core when the valve is closed. In a high-pressure pneumatic angle seat valve, the sealing ring needs to withstand higher pressure, so its material and processing method are very important.

[0003] The sealing ring belt of the high-pressure pneumatic angle seat valve seat is generally formed by stamping equipment, and there are many types of sealing rings. Therefore, the punch head needs to be removable and replaceable during the stamping process. The punch head of the existing stamping equipment is generally fixed by bolts or hanging platforms. The advantages of the bolt fixing method are easy disassembly and low processing and manufacturing costs. However, the staff needs to explore the interior of the equipment to install and disassemble the punch head, which is more dangerous. The advantages of the hanging platform fixing method are firmness, easy processing, and good strength, but the disadvantage is that it is inconvenient to disassemble. If the punch needs to be replaced, the upper die must be completely disassembled.

[0004] Therefore, we propose a high-pressure pneumatic angle seat valve seat sealing ring band stamping forming method to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the punching head of the existing stamping equipment generally adopts a bolt fixing method or a hanging table fixing method. The advantages of the bolt fixing method are easy disassembly and low processing and manufacturing cost, but it requires staff to probe into the interior of the equipment to install and disassemble the punching head, which is relatively dangerous. The advantages of the hanging table fixing method are firmness, easy processing and good strength, but the disadvantage is that it is inconvenient to disassemble. If the punch needs to be replaced, the upper mold must be completely disassembled. A high-pressure pneumatic angle seat valve seat sealing ring band stamping forming method is proposed.

[0006] The purpose of the present invention can be achieved by the following technical solution: comprising the following steps: Step 1: First, place the material to be stamped of the sealing ring belt of the high-pressure pneumatic angle seat valve seat on the lower die on the upper surface of the base, and then start the hydraulic cylinder, which drives the upper mounting seat and the upper die inside it to move vertically downward, so that the upper die contacts the lower die, thereby realizing the stamping and forming of the sealing ring belt of the high-pressure pneumatic angle seat valve seat; The lever is then pushed down to push the other end of the lever upward, and the horizontal lifting plate and the trapezoidal lifting block are then pushed upward, so that the trapezoidal lifting block pushes the two upper L-shaped wedge-shaped movable plates to the front and rear sides respectively, so that the two L-shaped wedge-shaped movable plates respectively drive the connected locking plug plates to move out of the locking plates, so that the locking plates lose the locking and fixing effect inside the mounting plate, and at the same time, the lever will synchronously drive the oblique connecting plate to move upward, and the oblique connecting plate will then drive the front sealing plate to move upward into the interior of the upper mounting seat, so that the front sealing plate loses its blocking effect on the ejection plate. Step 3: At this time, the upper mold can be moved upward, so that the upper mold drives the plug-in plate to move upward, and then the plug-in plate drives the locking plate to move out of the mounting plate, and then the upper mold can be moved forward horizontally and moved out of the upper mounting seat as a whole, and then a new upper mold of the corresponding model is horizontally inserted into the interior of the upper mounting seat; Step 4.

At the same time, the front end of the mounting plate will squeeze the push block forward, so that the push block pushes the wedge-shaped lifting block and the ejector plate upward through the push rod and the wedge-shaped horizontal moving block, so that the upper part of the ejector plate moves out of the plug-in board and abuts against the inner wall of the upper mounting seat. At this time, without external force, the front sealing plate The elastic force of the spring three is released to push the front sealing plate downward, so that the lower end of the front sealing plate is pushed out of the interior of the upper mounting seat, and the rear side of the front sealing plate is abutted against the front end of the ejection plate, further improving the front and rear fixing effect of the plug-in plate. At the same time, when there is no external force, the spring six pushes the locking plug plate inside the mounting plate into the interior of the locking plate, so that the locking plate cannot move in the vertical direction, and then fixes the locking plate inside the mounting plate, completing the installation of the upper mold, and then facilitating the subsequent stamping and forming of the sealing ring.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on 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.

[0019] Example: See Figure 1 - Fig. 9 As shown, a high-pressure pneumatic angle seat valve seat sealing ring band stamping forming method is implemented based on a high-pressure pneumatic angle seat valve seat sealing ring band stamping forming device, the device includes a base 1 and an upper mounting seat 5, and the upper mounting seat 5 is arranged above the base 1, and columns 2 are arranged at the four corners of the upper surface of the base 1, and a top plate 3 is arranged at the upper end of the column 2. A hydraulic cylinder 4 is arranged in the middle of the upper surface of the top plate 3, and the telescopic end of the hydraulic cylinder 4 is fixedly connected to the upper surface of the upper mounting seat 5, wherein a buffer component is arranged on the circumferential surface of the lower end of the column 2, which can buffer the upper mounting seat 5 when the hydraulic cylinder 4 drives the upper mounting seat 5 to stamp, thereby reducing the influence of the vibration generated when the device is working on the upper mounting seat 5;

[0020] The upper mold 7 is fixed to the interior of the upper mounting seat 5 through the plug-in plate 6, and the interior of the upper mounting seat 5 is provided with a mounting plate 8. A locking plate 601 is provided on the rear lower surface of the plug-in plate 6. The locking plate 601 is plugged into the interior of the mounting plate 8, and locking plug plates 801 are plugged into the interior of the front and rear sides of the locking plate 601. The upper end of the locking plug plate 801 is arc-shaped and the lower end is right-angled. The two locking plug plates 801 are movably installed in the interior of the mounting plate 8 through springs 6 802. L-shaped wedge-shaped movable plates 803 are provided on the lower surfaces of the two locking plug plates 801. A trapezoidal lifting block 804 is provided below the L-shaped wedge-shaped movable plate 803. The trapezoidal lifting block 804 is provided. When being able to move vertically upward, its two inclined surfaces can respectively abut against the two L-shaped wedge-shaped movable plates 803, thereby driving the two L-shaped wedge-shaped movable plates 803 to move horizontally, so that the two L-shaped wedge-shaped movable plates 803 can smoothly drive the two locking plug plates 801 to move out of the locking plate 601. The lower surface of the trapezoidal lifting block 804 is provided with a horizontal lifting plate 805, and the lower surface of the horizontal lifting plate 805 is movably mounted inside the mounting plate 8 through a positioning rod 806. The setting of the positioning rod 806 can limit the horizontal lifting plate 805, so that the horizontal lifting plate 805 can only move vertically, and will not deviate during the up and down movement to affect subsequent use; It should be noted that the upper end of the locking plug plate 801 is set at an arc shape and the lower end is set at a right angle. When the locking plate 601 is inserted vertically downward into the interior of the mounting plate 8, the locking plate 601 will squeeze the locking plug plate 801 into the interior of the mounting plate 8, so that the locking plate 601 can be smoothly inserted into the interior of the mounting plate 8. Then, after the locking plate 601 is inserted into the interior of the mounting plate 8 as a whole, the locking plug plate 801 is inserted into the interior of the locking plate 601 under the action of spring six 802. At this time, because the lower end of the locking plug plate 801 is set at a right angle, the locking plate 601 can no longer move upward out of the mounting plate 8, so that the locking plate 601 is fixedly installed inside the mounting plate 8, and then the plug-in board 6 is fixedly installed on the mounting plate 8.

[0021] The front side of the mounting plate 8 is in contact with a push block 602, and the push block 602 is movably mounted inside the rear side of the plug-in board 6 through a spring five 604, the front end of the push block 602 is connected to a push rod 603 through a spring five 604, the front end of the push rod 603 is provided with a wedge-shaped horizontal moving block 605, the front end of the wedge-shaped horizontal moving block 605 is in contact with a wedge-shaped lifting block 606, the upper end of the wedge-shaped lifting block 606 is provided with an ejector plate 607, and the ejector plate 607 is movably mounted inside the upper end of the plug-in board 6, the upper end of the ejector plate 607 is located above the plug-in board 6 and in contact with the inner wall of the upper mounting seat 5; It should be noted that Figure 4When the upper part of the middle ejector plate 607 is moved out of the plug-in board 6, the spring five 604 is not in the extreme compression state. When the plug-in board 6 is subsequently disassembled, the plug-in board 6 will move upward first. At this time, the ejector plate 607 will be pressed into the interior of the plug-in board 6, and then the ejector plate 607 will push the wedge-shaped horizontal moving block 605 and the push rod 603 to move horizontally backward through the wedge-shaped lifting block 606. Because the rear side of the push block 602 is still in contact with the front surface of the mounting plate 8, the push block 602 cannot be pushed backward. At this time, the push rod 603 will continue to compress the spring five 604, so that the ejector plate 607 can smoothly enter the interior of the plug-in board 6, and then the plug-in board 6 can be smoothly disassembled and assembled.

[0022] A lever 504 is provided below the horizontal lifting plate 805, and the upper surface of the lever 504 on the side away from the horizontal lifting plate 805 is in contact with the L-shaped lifting plate 501, and one end of the L-shaped lifting plate 501 extends to the outside of the upper mounting seat 5, and the L-shaped lifting plate 501 is movably mounted inside the upper mounting seat 5 by a spring 502. The setting of the spring 502 can push the L-shaped lifting plate 501 upward when there is no external force, so that the lower end of the L-shaped lifting plate 501 does not contact the upper surface of the lever 504, so as to prevent the L-shaped lifting plate 501 from accidentally touching the lever 504 after being subjected to the vibration generated when the device is working, so that the lever 504 rotates unnecessarily. A side seal is provided on the lower surface of the L-shaped lifting plate 501 on the side away from the lever 504 The upper mounting seat 505 is provided with a second spring 505, and the other end of the second spring 505 is connected to the inner part of the upper mounting seat 5. The setting of the second spring 505 can pull the lever 504 back to a horizontal state when the lever 504 is not subjected to an external force, so that the far end of the lever 504 does not contact the horizontal lifting plate 805, thereby preventing the lever 504 from affecting the horizontal lifting plate 805. The lowering plate 805 produces unnecessary movement. The front end of the lever 504 close to the horizontal lifting plate 805 is provided with an oblique connecting plate 506, and the front end of the oblique connecting plate 506 is provided with a front sealing plate 507. The setting of the oblique connecting plate 506 can synchronously drive the oblique connecting plate 506 to move upward when the lever 504 is rotated, so that the oblique connecting plate 506 can drive the front sealing plate 507 to move upward into the interior of the upper mounting seat 5, thereby making the front sealing plate 507 lose its limiting effect on the plug-in plate 6. The upper end of the front sealing plate 507 is movably mounted inside the front end of the upper mounting seat 5 by a spring three 508, and the lower end of the front sealing plate 507 abuts against the front end of the ejection plate 607. The setting of the spring three 508 can make the front sealing plate 507 not subject to external force. The lower end of the front sealing plate 507 moves out of the upper mounting seat 5, and then seals the front end of the plug-in slot of the upper mounting seat 5 to prevent external dust and impurities from entering the interior of the upper mounting seat 5, and at the same time limits and blocks the ejection plate 607 to improve the plug-in and fixing effect of the plug-in board 6. The rear side of the upper mounting seat 5 is movably connected with a push plate 510 through a spring four 509, and the front side of the push plate 510 abuts against the rear outer surface of the plug-in board 6. After the plug-in board 6 is installed in the upper mounting seat 5, the push plate 510 is pushed forward by the elastic force of the spring four 509, exerting a forward force on the plug-in board 6. Then, because of the blocking of the front sealing plate 507, the front sealing plate 507 and the front end of the ejection plate 607 are more closely attached, further improving the plug-in and fixing effect of the plug-in board 6 in the upper mounting seat 5. It should be noted that the fulcrum of the lever 504 is set on the side close to the L-shaped lifting plate 501, and the oblique connecting plate 506 is set on the side close to the horizontal lifting plate 805, so that when the lever 504 rotates, the oblique connecting plate 506 and the horizontal lifting plate 805 can move vertically upward at the same time.

[0023] The mounting plate 8 is provided with a movable groove 19 inside, and the locking plug plate 801, the spring 6 802, the L-shaped wedge-shaped movable plate 803, the trapezoidal lifting block 804, the horizontal lifting plate 805 and one end of the lever 504 are all arranged inside the movable groove 19. The setting of the movable groove 19 provides a plug-in space for the locking plug plate 801, so that the locking plug plate 801 can be smoothly inserted into the mounting plate 8, and provides a moving or rotating space for the L-shaped wedge-shaped movable plate 803, the trapezoidal lifting block 804, the horizontal lifting plate 805 and the lever 504, so that the L-shaped wedge-shaped movable plate 803 can be smoothly moved horizontally, the trapezoidal lifting block 804 and the horizontal lifting plate 805 can be smoothly moved vertically, and the lever 504 can be smoothly rotated. The upper mounting seat 5 is provided with a movable groove 2 10 and a movable groove 3 11 inside. , and the rear ends of the movable groove 2 10 and the movable groove 3 11 are connected, wherein one end of the lever 504 is arranged inside the movable groove 1 9, and the other end is arranged inside the movable groove 2 10, so the movable groove 1 9 and the movable groove 2 10 are connected, and the end of the lever 504 close to the L-shaped lifting plate 501, the L-shaped lifting plate 501, the spring 1 502 and the spring 2 505 are all arranged inside the movable groove 2 10. The setting of the movable groove 2 10 provides a movable space for the L-shaped lifting plate 501 and the lever 504, so that the L-shaped lifting plate 501 can move vertically smoothly, and the lever 504 can rotate smoothly. The oblique connecting plate 506 is arranged inside the movable groove 3 11. The setting of the movable groove 3 11 provides a movable space for the oblique connecting plate 506, so that the oblique connecting plate 506 can move vertically smoothly.

At this time, the L-shaped lifting plates 501 located on the left and right ends of the upper mounting seat 5 on the outside of the upper mounting seat 5 are first pressed down to make the L-shaped lifting plate 501 move downward, and then the lower end of the L-shaped lifting plate 501 presses down one end of the lever 504 to lift the other end of the lever 504 upward, and then the horizontal lifting plate 805 and the trapezoidal lifting block 804 are pushed upward to make the trapezoidal The lifting block 804 pushes the two upper L-shaped wedge-shaped movable plates 803 to the front and rear sides respectively, so that the two L-shaped wedge-shaped movable plates 803 respectively drive the connected locking plug plates 801 to move out of the locking plate 601, so that the locking plate 601 loses the locking and fixing effect inside the mounting plate 8, and at the same time, the lever 504 also synchronously drives the oblique connecting plate 506 to move upward, and the oblique connecting plate 506 drives the front sealing plate 507 to move upward into the interior of the upper mounting seat 5, so that the front sealing plate 507 loses the blocking effect on the ejection plate 607; Step 3: At this time, the upper mold 7 can be moved upward, so that the upper mold 7 drives the plug-in board 6 to move upward, and then the plug-in board 6 drives the locking plate 601 to move out of the mounting plate 8, and then the upper mold 7 can be moved forward horizontally and moved out of the upper mounting seat 5 as a whole, and then a new upper mold 7 of the corresponding model is horizontally inserted into the interior of the upper mounting seat 5; Step 4, when the upper mold 7 drives the plug-in board 6 to move into the upper mounting seat 5, the rear end of the plug-in board 6 will first push the push plate 510 backwards, and then after the plug-in board 6 is moved into the upper mounting seat 5 as a whole, the plug-in board 6 is moved downward, and the plug-in board 6 drives the locking plate 601 to be inserted into the interior of the mounting plate 8. At the same time, the front end of the mounting plate 8 will squeeze the push block 602 forward, so that the push block 602 pushes the wedge-shaped lifting block 606 and the ejection plate 607 upward through the push rod 603 and the wedge-shaped horizontal moving block 605, so that the upper part of the ejection plate 607 moves out of the plug-in board 6 and abuts against the inner wall of the upper mounting seat 5.

The lifting block (804) is pushed upward, so that the trapezoidal lifting block (804) pushes the two upper L-shaped wedge-shaped movable plates (803) to the front and rear sides respectively, so that the two L-shaped wedge-shaped movable plates (803) respectively drive the connected locking plug plates (801) to move out of the locking plate (601), and at the same time, the lever (504) synchronously drives the oblique connecting plate (506) to move upward, and the oblique connecting plate (506) then drives the front sealing plate (507) to move upward into the interior of the upper mounting seat (5); Step 3: At this time, the upper mold (7) is moved upward, so that the upper mold (7) drives the plug-in plate (6) to move upward, and then the plug-in plate (6) drives the locking plate (601) to move out of the mounting plate (8), and then the upper mold (7) can be moved horizontally forward and moved out of the upper mounting seat (5) as a whole, and then a new upper mold (7) of the corresponding model is horizontally inserted into the interior of the upper mounting seat (5); Step 4. When the upper mold (7) drives the plug-in board (6) to move into the interior of the upper mounting seat (5), the rear end of the plug-in board (6) first pushes the push plate (510) backwards, and then after the plug-in board (6) is moved as a whole into the interior of the upper mounting seat (5), the plug-in board (6) is moved downward, and the plug-in board (6) drives the locking plate (601) to be inserted into the interior of the mounting plate (8). At the same time, the front end of the mounting plate (8) squeezes the push block (602) forward, so that the push block (602) pushes the wedge-shaped lifting block (606) and the ejection plate (607) upwards through the push rod (603) and the wedge-shaped horizontal moving block (605), so that the upper part of the ejection plate (607) moves out of the plug-in board (6) and abuts against the inner wall of the upper mounting seat (5). At this time, In the absence of external force, the elastic force of the spring three (508) above the front sealing plate (507) is released, pushing the front sealing plate (507) downward, so that the lower end of the front sealing plate (507) is pushed out of the interior of the upper mounting seat (5), and the rear side of the front sealing plate (507) is abutted against the front end of the ejection plate (607). At the same time, in the absence of external force, the locking plug plate (801) inside the mounting plate (8) is pushed into the interior of the locking plate (601) by the spring six (802), so that the locking plate (601) cannot move in the vertical direction, and then the locking plate (601) is fixed inside the mounting plate (8), completing the installation of the upper mold (7), and then carrying out the subsequent stamping and forming of the sealing ring.
