Description

Technical Field

[0001] The invention relates to the technical field of diaphragm stamping, in particular to a diaphragm stamping forming device for a metal sealing valve seat. Background Art

[0002] The valve seat diaphragm refers to the diaphragm structure that plays a sealing and isolating role in the valve. It is usually made of elastic materials such as rubber, fluororubber, polytetrafluoroethylene, etc. It has good sealing and corrosion resistance. When the valve seat diaphragm is formed, stamping equipment is needed to perform stamping processing;

[0003] In the stamping and forming equipment in the prior art, after the sensor diaphragm is stamped and formed, the upper mold is separated from the lower mold, so that the first electric push rod can push the diaphragm upward through the top block, and then the movable plate is driven to move by the adjusting component, so that the movable plate can drive the plug plate to move to the outer wall of the top block, and then the fixed block is driven to rotate by the lifting mechanism, so that the plug plate can be moved upward, so that the diaphragm is separated from the top block and moved to the upper end of the plug plate, and because the movable plate is in an inclined position, the diaphragm can slide on the upper end of the movable plate, and at the same time, the movable plate is driven to reset by the adjusting component, and guided by the guide block, the diaphragm can slide down to complete the demoulding work of the diaphragm, which not only saves the inconvenience caused by manual demoulding, but also can effectively improve the demoulding efficiency of the diaphragm, thereby improving the production efficiency of the sensor diaphragm;

[0004] However, in the prior art, when the upper mold of the stamping equipment moves downward, the punching opening is formed, and the upper mold moves upward and is separated from the lower mold. After separation, the punched diaphragm is taken out. This does not make full use of the time wasted in the process of the upper mold moving up and down. Therefore, there is room for improvement.

[0038] The transmission structure includes a fixed column 20 connected to the top of the rotating column 12, a first connecting rod 19 is connected to the middle of one side of the lifting plate 9 near the fixed column 20, a lifting sleeve 21 is connected to one end of the first connecting rod 19, and the lifting sleeve 21 is movably sleeved on the fixed column 20, and the fixed column 20 is provided with two first vertical grooves 23 and two second vertical grooves 26, the first vertical grooves 23 and the second vertical grooves 26 are arranged at intervals, and a first driving groove 24 is provided on one side of the top of the first vertical groove 23, and the first driving groove 24 The upper end of the lifting sleeve 21 is connected to the top of one of the second vertical slots 26 adjacent to the first vertical slot 23, and a second driving slot 25 is provided on the other side of the top of the first vertical slot 23. The upper end of the second driving slot 25 is connected to the top of another second vertical slot 26 adjacent to the first vertical slot 23. A plug rod 22 is fixedly inserted into the position near the top of the side of the lifting sleeve 21. One end of the plug rod 22 is slidably arranged at the top of the second vertical slot 26. When the diaphragm in the lower mold 3 in the sleeve 15 placed on the support plate 4 is stamped, the first electric push is started. The rod 8 drives the lifting plate 9 to move downward on the first vertical rod 6, thereby driving the upper mold 10 to pass through the through-hole 11, and stamping the diaphragm in the lower mold 3. The support plate 4 supports the lower mold 3, so that the stamping work can be smoothly carried out in the lower mold 3 and the placement sleeve 15. The downward movement of the lifting plate 9 drives one end of the insertion rod 22 on the lifting sleeve 21 to slide down from the first driving groove 24 to the second vertical groove 26 through the first connecting rod 19. The insertion rod 22 slides downward in the second vertical groove 26 In the process, the rotating column 12 remains in position, so that the upper mold 10 moves downward, and the stamping work can be carried out smoothly. After stamping, the lifting plate 9 and the upper mold 10 move upward as a whole, driving one end of the insertion rod 22 on the lifting sleeve 21 to slide from the second vertical groove 26 to the first driving groove 24.

The storage cylinder 27 is located directly above the corresponding lower mold 3. When the rotating column 12 drives the baffle 17 and the lower mold 3 to rotate as a whole, when the baffle 17 rotates close to the bottom of the storage cylinder 27, the baffle 17 blocks the diaphragm to be stamped stored in the storage cylinder 27. When the rotating column 12 rotates the empty lower mold 3 to the bottom of the storage cylinder 27, the bottom diaphragm in the storage cylinder 27 falls into the lower mold 3, and automatic loading is performed.

When the rotating column 12 drives the corresponding diaphragm punched in the lower mold 3 to rotate, it drives the through rod 34 to slide to the convex strip 36. When the through rod 34 slides on the inclined surface of the convex strip 36, it drives the first driving frame 32 to move downward on the first fixed frame 31, compressing the first spring 33, and driving the corresponding flip rod 14 and the placement sleeve 15 to rotate half a circle as a whole through the second gear. The lower mold 3 moves downward on the placement sleeve 15, and the gravity of the lower mold 3 and the gravity of the diaphragm are used to facilitate the falling of the formed diaphragm from the lower mold 3, and automatic unloading is performed. The limiting sleeve 16 on the placement sleeve 15 limits the lower mold 3 to avoid the problem of the lower mold 3 falling directly from the placement sleeve 15.

[0041] The pushing structure includes a second fixing frame 38 installed on the side of the chassis 1, the second fixing frame 38 is arranged close to the second vertical rod 29, a second electric push rod 39 is installed on the top of the second fixing frame 38, a top plate 40 is installed on the top of the output shaft of the second electric push rod 39, two fourth vertical rods 41 are connected to the edge below the top plate 40, the fourth vertical rods 41 movably pass through the second fixing frame 38, a sleeve 42 is movably sleeved on the bottom end of each fourth vertical rod 41, a fixing strip is sleeved on the upper inner wall of the second fixing frame 38 on the two fourth vertical rods 41, a second spring 44 is sleeved on the fourth vertical rod 41, two ends of the second spring 44 are respectively connected to the fixing strip and the top of the sleeve 42, a pushing sleeve 43 is installed on the top of the two sleeves 42, and a knocking structure is provided on the fixing strip;

After the corresponding placement sleeve 15 and the lower mold 3 are turned over as a whole, in order to avoid the situation that the formed diaphragm cannot be unloaded due to being clamped to the lower mold 3 and the placement sleeve 15, the second electric push rod 39 can be started to drive the top plate 40 to move downward, and the pushing sleeve 43 is driven downward by the fourth vertical rod 41 and the sleeve 42. The downward movement of the pushing sleeve 43 can be used to push the lower mold 3 in the placement. The placing sleeve 15 moves downward until the limiting sleeve 16 is supported on the placing sleeve 15. Then, the top plate 40 continues to move downward. Since the position of the pushing sleeve 43 remains unchanged, the sleeve 42 moves upward relatively on the fourth vertical rod 41, squeezing the second spring 44 to compress. The upward movement of the sleeve 42 drives the second driving frame 61 at one end of the connecting plate 62 to move upward, and drives the rotating shaft 56 to rotate through the first gear 60. The lever 59 on the second fixed sleeve 57 at one end of the rotating shaft 56 drives the driving rod 58 to automatically drive the rotating tube 52 and the rotating handle 53 to rotate as a whole, and through the fixed rod 54 and the curved rod 55, in cooperation with the elastic force of the third spring 50, the knocking rod 48 and the knocking block 51 can be automatically driven to move up and down as a whole to automatically knock on the lower mold 3, so that the diaphragm formed in the lower mold 3 can be discharged more smoothly, and the situation of discharge jamming can be reduced.

[0045] The implementation principle of the diaphragm stamping and forming equipment of the metal sealing valve seat in the embodiment of the present invention is as follows: during stamping, the first electric push rod 8 is started to drive the lifting plate 9 to move downward on the first vertical rod 6, thereby driving the upper mold 10 to pass through the through-hole 11, and the diaphragm is stamped and formed in the lower mold 3. The support plate 4 supports the lower mold 3, so that the stamping work can be smoothly carried out in the lower mold 3 and the placement sleeve 15. The downward movement of the lifting plate 9 drives one end of the insertion rod 22 on the lifting sleeve 21 to slide down from the first driving groove 24 to the second vertical groove 26 through the first connecting rod 19. During the process of the insertion rod 22 sliding downward in the second vertical groove 26, the rotating column 12 remains in position, so that the upper mold 10 moves downward and the stamping work can be carried out smoothly. After stamping, the lifting plate 9 and the upper mold 10 move upward as a whole, driving one end of the insertion rod 22 on the lifting sleeve 21 to slide from the second vertical groove 26 to the first driving groove 24. As the lifting plate 9 drives the insertion rod 22 to continue to move upward, one end of the insertion rod 22 squeezes part of the groove wall in the first driving groove 24, pushing the rotating column 12 to rotate until one end of the insertion rod 22 slides to the upper end of the second driving groove 25. Then the first electric push rod 8 drives the lifting plate 9 and the upper mold 10 to move downward as a whole, driving one end of the insertion rod 22 to slide downward in the second driving groove 25, and by squeezing the groove wall of the second driving groove 25, driving the rotating column 12 to continue to rotate, driving the baffle 17 to rotate close to the bottom of the storage tube 27, the baffle 17 blocks the diaphragm to be stamped stored in the storage tube 27, and when the rotating column 12 rotates the remaining lower mold 3 to the bottom of the storage tube 27, the bottom diaphragm in the storage tube 27 falls into the lower mold 3, and the remaining diaphragm is automatically transported to the first fixed frame 2 for stamping. At the same time, the stamped diaphragm rotates toward the second fixed frame 38, and the rotating column 12 drives the through rod 34 to slide to the convex strip 36. The through rod 34 slides on the inclined surface of the convex strip 36, driving the first driving frame 32 to move downward on the first fixed frame 31, compressing the first spring 33, and driving the corresponding flip rod 14 through the second gear. The lower mold 3 moves downward on the placement sleeve 15, and the gravity of the lower mold 3 and the gravity of the diaphragm are used to facilitate the falling of the formed diaphragm from the lower mold 3. When the diaphragm is stuck and cannot be unloaded smoothly, the second electric push rod 39 can be started to drive the top plate 40 to move downward, and the top plate 40 drives the pushing sleeve 43 to move down to the limiting sleeve 16, and the knocking block 51 is pressed against the lower mold 3, and the top plate 40 continues to move downward. Since the position of the pushing sleeve 43 remains unchanged, the sleeve 42 moves upward on the fourth vertical rod 41, squeezing the second spring 44 to be compressed. The upward movement of the sleeve 42 drives the second driving frame 61 at one end of the connecting plate 62 to move upward, and drives the rotating shaft 56 to rotate through the first gear 60. The lever 59 on the second fixed sleeve 57 at one end of the rotating shaft 56 drives the driving rod 58, which can automatically drive the rotating tube 52 and the rotating handle 53 to rotate as a whole, and through the fixed rod 54 and the curved rod 55,With the elastic force of the third spring 50, the knocking rod 48 and the knocking block 51 can be automatically driven to move up and down as a whole to automatically knock the lower mold 3, so that the diaphragm formed in the lower mold 3 can be unloaded more smoothly and the situation of unloading jamming can be reduced, so that the stamping and forming of the diaphragm can be completed.

[0046] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
