Description

Technical Field

[0001] This invention relates to the field of flange gasket punching equipment, specifically a rapid automatic punching device for processing sealing components. Background Technology

[0002] Flange gaskets are elastic / rigid elements sandwiched between the sealing surfaces of two flanges when connecting pipes and equipment flanges. Common types include soft gaskets: rubber gaskets (nitrile rubber, fluororubber), asbestos gaskets (to be phased out), graphite composite gaskets; semi-metallic gaskets: metal-clad gaskets (metal shell + non-metallic core material), corrugated composite gaskets; and metallic gaskets: copper gaskets, stainless steel gaskets, and lens gaskets (suitable for high-pressure and high-temperature conditions, such as chemical and power equipment).

[0003] Soft gaskets are mainly produced through compression molding. The pre-treated blank is placed into a custom mold (the mold cavity matches the shape of the finished gasket), and pressure (5-20 MPa) is applied using a hydraulic press while simultaneously controlling the temperature (e.g., for rubber gaskets, heating and vulcanization are required at 150-200℃). This causes the blank to conform to the mold, forming the "main sealing surface" of the gasket. After the main gasket is formed, bolt holes are machined using specialized equipment according to the parameters of the flange bolt holes (i.e., "punching") to ensure that the bolts can penetrate the gasket to fix the flange. Common punching equipment includes manual punching machines (manual crank + punch + positioning fixture); semi-automatic hydraulic punching machines (hydraulic driven punch + CNC positioning table); and fully automatic CNC machine tools (CNC system + multi-station mold + feeding mechanism).

[0004] For some manual punching machines / small-batch semi-automatic equipment, the operator usually places the shim blank on the "positioning fixture" of the punching machine (the fixture has a recessed jig groove that matches the inner hole / outer circle of the shim to ensure that the center of the blank is aligned with the center of the punch). Then, the operator manually or using a clamping plate gently presses the shim (for soft shims, the pressure needs to be controlled to avoid deformation; for metal shims, a little force can be applied to prevent displacement during punching). When punching, the operator manually moves the crank or starts the equipment. After punching one hole (some semi-automatic equipment can punch multiple holes at the same time), the operator rotates the shim (by using the indexing plate of the fixture to divide the angle equally according to the number of bolt holes, such as 90° for 4 holes). This process is repeated until all holes are processed. Finally, the operator manually removes the punched shim from the recessed jig groove.

[0005] The positioning fixture is the core component for positioning the shim blank, used to ensure the accuracy of the blank punching. Because the pressure needs to be controlled during the fixing of soft shims to avoid deformation, the positioning fixture for soft shims is usually a grooved jig (metal shims can be clamped using positioning clamps). When using a recessed positioning jig, the operator needs to calibrate it while placing the blank to ensure that the blank can fit perfectly into the jig groove. If the blank is not placed evenly, it will cause punching deviation. After the blank is punched, the operator still needs to manually remove the shim from the recessed jig groove. The jig groove usually also has a through hole larger than the center hole of the shim. That is, the center hole of the shim is often smaller than the through hole of the jig groove. The edge of the center hole of the shim is a protruding part relative to the through hole of the jig groove. The operator can remove the shim by grabbing the protruding part. Therefore, when punching and unloading soft shims, the calibration work during loading and the manual insertion into the jig groove to grab the shim during unloading will affect the efficiency of shim punching. Summary of the Invention

[0006] Therefore, the purpose of this invention is to provide a rapid automatic drilling device for processing sealing components, so as to solve the technical problems mentioned in the background above.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rapid automatic drilling device for processing sealing components, comprising a cabinet, an internal working plate connected to a drive assembly, and a punching fixture for supporting blanks on the side of the working plate. The punching fixture includes a fixture plate with multiple sets of circular punches on its top and a tapered guide surface on its top edge. A movable plate is movably mounted inside the cabinet via multiple sets of guide rods. A first telescopic assembly is installed inside the cabinet, with its output end connected to the top of the movable plate. A punching mechanism is mounted at the bottom of the movable plate, comprising a mounting frame with multiple sets of punch rods matching the circular punches at its bottom. A clamping table is movably mounted on the outside of the rod. The clamping table and the mounting frame are connected by a first spring. A correction block is mounted on the side of the clamping table by a second spring. The correction block matches the conical guide surface. A second telescopic assembly is installed inside the equipment cabinet. A connecting plate is connected to the top of the second telescopic assembly. A feeding mechanism is rotatably connected to the bottom of the connecting plate. The feeding mechanism includes a sleeve. A movable block is movably mounted inside the sleeve by a limit rod and a third spring. A top rod is provided on the side of the movable block. A fixed rod is rotatably connected inside the equipment cabinet. A pressing wheel for pushing the top rod is provided at the bottom of the fixed rod. A drive device is mounted inside the equipment cabinet by a crossbeam. A square drive shaft is connected to the bottom of the drive device. The square drive shaft and the fixed rod are movably connected through each other.

[0008] By adopting the above technical solution, the efficiency of punching the gasket blank can be improved by setting a punching mechanism. The punching mechanism includes multiple sets of punches, which can complete the punching of the gasket blank in one go. Furthermore, the pressing table of the punching mechanism is equipped with multiple sets of inwardly retractable correction blocks on its side. The top edge of the punching fixture used for positioning the blank is set with a tapered guide surface. The inner side of the tapered guide surface matches the blank size, enabling blank positioning, while the outer dimension of the tapered guide surface is larger than the blank, meaning the open-type fixture plate is more efficient. It allows workers to manually place the blanks without needing to precisely correct their placement. Even if there is an angle deviation in the blank placement and it is not fully embedded in the fixture plate but instead rests on one side of the tapered guide surface, when the punching mechanism descends, it causes multiple sets of correction blocks to descend as well. These blocks slide along the tapered guide surface, squeezing and pushing the offset blank into the fixture slot. In other words, when the punching mechanism and punching fixture are in contact during punching, they can automatically correct blanks with angle deviations, saving workers' time and improving the punching efficiency of the shims.

[0009] The present invention is further configured such that the working plate includes a loading station located on one side of the equipment cabinet window, a punching station located below the punching mechanism, an empty station, and a unloading station located below the unloading mechanism, and multiple sets of punching fixtures are evenly arranged on the side of the working plate, and the multiple sets of punching fixtures are rotated and switched between different stations.

[0010] Preferably, by setting up multiple sets of punching fixtures to rotate between different workstations, the punching process of the gaskets, including feeding, punching, and unloading, can be carried out simultaneously, thereby improving the punching efficiency of the gaskets.

[0011] The invention is further configured such that the top of the pressing table has multiple sets of second through holes that match the punch rod, and the top of the pressing table is provided with an extension rod, the first spring is sleeved on the outside of the extension rod, and the extension rod and the mounting bracket are movably connected through each other.

[0012] Preferably, by setting an extension rod to movably install the mounting bracket and the clamping platform, the height adjustment of the clamping platform is made more stable.

[0013] The present invention is further configured such that multiple sets of correction blocks are provided, and each set of correction blocks is movably mounted on the side of the pressing table by means of a second spring, and the multiple sets of correction blocks are evenly distributed.

[0014] Preferably, multiple sets of correction blocks are set to correct the billet that has a positional shift, so that the billet can be corrected no matter which direction it shifts.

[0015] The present invention is further configured such that the active blocks are provided in multiple groups, and the multiple groups of active blocks are evenly distributed.

[0016] Preferably, by setting multiple sets of evenly distributed movable blocks, the feeding mechanism can grip the pad more stably.

[0017] The present invention is further configured such that a first through hole is provided on the top of the fixture disk, the maximum diameter of the expansion of the plurality of movable blocks is smaller than the first through hole, and the maximum diameter of the expansion of the plurality of movable blocks is larger than the center hole of the blank.

[0018] Preferably, by precisely setting the expansion and contraction distances of multiple sets of movable blocks, they can pass through the central hole of the gasket when contracting and can grip the gasket when expanding.

[0019] The present invention is further configured such that a rotary valve is provided at the bottom of the extrusion wheel, the rotary valve being used to manually drive the extrusion wheel to rotate.

[0020] Preferably, by providing a rotary valve at the bottom of the extrusion roller, the feeding mechanism can be adjusted not only by the drive device but also manually.

[0021] The present invention is further configured such that a material support rod is installed inside the equipment cabinet via a linear moving module, the material support rod is located at the unloading station, and an unloading trough is provided inside the equipment cabinet, the unloading trough is located at the punching station.

[0022] Preferably, the material support rod is installed by setting a linear moving module. When the material support rod carries multiple pads, it can be driven to the window of the equipment cabinet by the linear moving module, making it convenient for staff to pick them up. The linear moving module can be a screw drive mechanism.

[0023] In summary, the present invention has the following main beneficial effects:

[0024] This invention improves the efficiency of punching gasket blanks by incorporating a punching mechanism. The punching mechanism includes multiple sets of punches, enabling the punching of the gasket blank in a single operation. Furthermore, the pressing table of the punching mechanism has multiple sets of inwardly retractable correction blocks on its side. The jig disc of the punching fixture used for positioning the blank has a tapered guide surface at its top edge. The inner side of the tapered guide surface matches the blank size for accurate positioning, while the outer side of the tapered guide surface is larger than the blank, meaning the open-type jig disc facilitates operation. The operator can manually place the blank without precise alignment. Even if there is an angle deviation in the blank placement and it is not fully embedded in the fixture plate but instead rests on the tapered guide surface, the punching mechanism descends, causing multiple sets of correction blocks to descend as well. These blocks slide along the tapered guide surface, squeezing and pushing the offset blank into the fixture slot. In other words, when the punching mechanism and punching fixture are in contact during punching, they can automatically correct blanks with angle deviations, saving operator time and improving the punching efficiency of the shims.

[0025] This invention utilizes a feeding mechanism to automatically feed punched shims from a punching fixture, thereby improving the efficiency of shim punching and feeding. The feeding mechanism mainly consists of a sleeve, an extrusion wheel, and multiple sets of movable blocks. The movable blocks are movably mounted on the side of the sleeve. By rotating the extrusion wheel, the retraction / extension state is controlled. When the feeding mechanism descends to pass through the punching fixture and the shim on top of it, the movable blocks first retract to ensure that the feeding mechanism can smoothly pass through the shim. Then, the movable blocks extend, and the feeding mechanism rises, bringing the shim out of the punching fixture along with it. This process can be repeated to stack multiple shims on the outside of the feeding mechanism, which can then be removed all at once. The feeding mechanism can not only automatically remove shims from the punching fixture but also stack shims removed multiple times, improving the efficiency of shim punching and feeding.

Figure 2 The work tray 2 includes a loading station located on one side of the window of the equipment cabinet 1, a punching station located below the punching mechanism 8, an empty station, and a unloading station located below the unloading mechanism 11. Multiple sets of punching fixtures 3 are evenly arranged on the side of the work tray 2. The multiple sets of punching fixtures 3 are located in different stations and rotate. By setting multiple sets of punching fixtures 3 to rotate between different stations, the punching work of the gasket, including loading, punching, and unloading, can be carried out simultaneously, thereby improving the punching efficiency of the gasket.

[0044] Please refer to the above embodiments for further details. Figures 3-7 The top of the pressing table 803 has multiple sets of second through holes 806 that match the punch 802, and the top of the pressing table 803 is provided with an extension rod 804.

[0047] Please refer to the above embodiments for further details. Figure 12 The top of the fixture disk 301 is provided with a first through hole 303. The maximum diameter of the expansion of the multiple sets of movable blocks 1104 is smaller than the first through hole 303, and the maximum diameter of the expansion of the multiple sets of movable blocks 1104 is larger than the center hole of the blank. By precisely setting the expansion and contraction distance of the multiple sets of movable blocks 1104, it can pass through the center hole of the gasket when it contracts and can grab the gasket when it expands.

[0048] Please refer to the above embodiments for further details. Figure 9 A rotary valve 1108 is provided at the bottom of the extrusion roller 1107. The rotary valve 1108 is used to manually drive the extrusion roller 1107 to rotate. By providing the rotary valve 1108 at the bottom of the extrusion roller 1107, the feeding mechanism 11 can be adjusted not only by the drive device 13, but also manually.

[0049] Please refer to the above embodiments for further details. Figure 1Inside the equipment cabinet 1, a material support rod 15 is installed via a linear motion module. The material support rod 15 is located at the unloading station. Inside the equipment cabinet 1, there is a material unloading chute 4 located at the punching station. The material support rod 15 is installed via a linear motion module. When the material support rod 15 carries multiple pads, it can be driven to the window of the equipment cabinet 1 via the linear motion module for easy access by the staff. The linear motion module can be a screw drive mechanism.

[0050] In practical operation, the present invention works as follows: First, the operator sequentially places multiple blanks of pads into the punching fixture 3 at the loading station. Then, the drive assembly at the bottom of the working plate 2 rotates the punching fixture 3 at the loading station to the punching station. The first telescopic assembly 7 is activated to push the movable plate 6 to slide down along the guide rod 5. The movable plate 6 then pushes the punching mechanism 8 down. The punching mechanism 8 descends and actively engages with the punching fixture 3 at the punching station. During the descent of the punching mechanism 8, multiple sets of correction blocks 808 of the punching mechanism 8 engage with the top edge of the conical guide surface 304 of the punching fixture 3. If the blank is misplaced, the punching mechanism 8 continues to descend, using the multiple sets of correction blocks 808 to squeeze and push the blank so that it is smoothly fitted into the fixture plate 301, while punching. During the descent of mechanism 8, due to the reverse force of the tapered guide surface 304 on multiple sets of correction blocks 808, the multiple sets of correction blocks 808 will also compress the second spring 807 and retract into the interior of the pressing table 803 until the correction blocks 808 are completely retracted into the interior of the pressing table 803. At this time, the pressing table 803 is just in contact with and gently presses the blank. At this time, the mounting frame 801 continues to descend, which will drive multiple sets of punches 802 to further pass through the second through hole 806 of the pressing table 803. The mounting frame 801 slides along the extension rod 804 to compress the first spring 805. The multiple sets of punches 802 pass through the second through hole 806 and through the 320 of the punching fixture 3 to complete the punching work on the blank. The waste generated by punching falls into the discharge trough 4 and is collected by the waste bucket. Then the punching mechanism 8 is reset.

[0051] Meanwhile, at the unloading station, the second telescopic component 9 operates, causing the connecting plate 10 to descend. The connecting plate 10 then drives the unloading mechanism 11 connected to it to descend. Simultaneously, the drive device 13 operates, causing the square transmission shaft 14 to rotate. The square transmission shaft 14 drives the fixed rod 1106 of the unloading mechanism 11 to rotate. The rotation of the fixed rod 1106 adjusts the extrusion wheel 1107, preventing it from extruding the top rod 1105 on the side of the multiple movable blocks 1104. Consequently, under the reset action of the third spring 1103, the multiple movable blocks 1104 slide and retract along the limit rod 1102 into the sleeve 1101. At this point, the unloading mechanism 11 can smoothly pass through the center hole of the gasket. When the height of the multiple movable blocks 1104 of the unloading mechanism 11 drops below that of the gasket, the drive device is restarted. 13 drives the square drive shaft 14 to rotate, causing the extrusion wheel 1107 to press the top rod 1105 of the multiple sets of movable blocks 1104, that is, to make the multiple sets of movable blocks 1104 extend out of the sleeve 1101. The diameter of the movable blocks 1104 in the extended state is still smaller than the diameter of the first through hole 303. At this time, the second telescopic component 9 is activated in the reverse direction to drive the unloading mechanism 11 to rise. The extended multiple sets of movable blocks 1104 can be used to grab and raise the gasket together. When the gasket is grabbed multiple times, the gaskets that already exist outside the unloading mechanism 11 will be supported on the top of the gasket inside the punching fixture 3 of the unloading station when the multiple sets of movable blocks 1104 retract. Then, together with the gasket inside the punching fixture 3 of the unloading station, they are grabbed out. In this way, multiple punched gaskets can be stacked together.

[0052] When the unloading mechanism 11 is carrying a certain number of pads, the working plate 2 is controlled to rotate to avoid the support rod 15. Then the height of the unloading mechanism 11 drops so that multiple sets of pads can be loosened and fitted onto the outside of the support rod 15. Then the linear moving module at the bottom of the support rod 15 drives the support rod 15 to approach the worker, and the worker can take out the stacked pads.

[0053] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, but such modifications, substitutions, and variations are protected by patent law as long as they are within the scope of the claims of the present invention.
