Forming press for manhole cover machining

Abstract

This utility model relates to the field of manhole cover processing technology, specifically a molding and pressing machine for manhole cover processing. It includes an operating table with a bottom mold for manhole cover processing bolted inside. After the manhole cover is processed, cylinder B inside the operating table moves a transmission plate, causing the transmission plate to move a top rod longitudinally upwards. This, in turn, causes the transmission plate to move the manhole cover on one side of the rubber plate out of the bottom mold. Motor A outside the operating table drives a bidirectional lead screw to rotate via a reducer A. Threaded blocks A and B move axially towards each other outside the bidirectional lead screw. Threaded block A then moves drive rod A, and threaded block B moves drive rod B, causing the blades inside drive rods A and B to contact the surface of the manhole cover. This removes and grinds the side scraps of manhole covers of different specifications, improving processing efficiency. Simultaneously, the rubber plate at the top of the top rod seals the top of the bottom mold, preventing the removed side scraps from falling into the bottom mold.

Description

Technical Field

[0001] This utility model relates to the field of manhole cover processing technology, specifically to a molding and pressing machine for manhole cover processing. Background Technology

[0002] Manhole covers are used to cover deep wells in roads or homes to prevent people or objects from falling in. They can be classified by material into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. They are generally round or square and can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc.

[0003] Patent No. 202220460166.1 discloses a molding and pressing machine for manhole cover production and processing. This device has the ability to automatically demold and conveniently modify the shape, thereby effectively reducing the labor intensity of workers and improving the convenience and efficiency of manhole cover processing by the molding and pressing machine.

[0004] However, existing molding and pressing machines for manhole cover production use grinding rods and T-shaped trimming blades to cut and grind off excess scraps from the manhole cover. However, the positions of the blades and grinding rods need to be manually adjusted by the workers, which cannot be adapted to different specifications of manhole covers, thus affecting the processing efficiency of manhole covers. At the same time, after the excess scraps from the manhole cover are cut off, they fall into the bottom mold. If they are not cleaned in time, they will affect the processing quality of the subsequent manhole covers and the service life of the bottom mold. Therefore, a molding and pressing machine for manhole cover processing is proposed. Utility Model Content

[0005] To address the problems in the background art, this utility model provides a molding press machine for manhole cover processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a molding and pressing machine for processing manhole covers, including an operating table. A bottom mold for processing manhole covers is bolted to the inside of the operating table. A top rod is inserted into the bottom of the bottom mold. A transmission plate is rotatably connected to the bottom of the top rod through a bearing. A rubber plate is screwed to the end of the top rod away from the transmission plate. A cylinder B for providing power is bolted to the bottom of the inner side of the operating table, and the power output end of the cylinder B is bolted to the bottom of the transmission plate. A motor A for providing power is bolted to the outside of the operating table, and a reducer A is flanged to one side of the motor A. A double-acting lead screw is keyed to one side of the reducer A, and threaded blocks A and B are threaded to the outside of the double-acting lead screw. A drive rod A is welded to the outside of threaded block A, and a drive rod B is welded to the outside of threaded block B. A blade for processing manhole covers is screwed to the outside of drive rod A, and a grinding block for grinding manhole covers is screwed to the outside of drive rod B. Support sleeves are welded to the bottom of both drive rod A and drive rod B, and a fixing rod is slidably connected to the inside of the support sleeve.

[0007] Specifically, after the manhole cover is processed, cylinder B inside the operating table drives the transmission plate to move, which in turn drives the top rod to move longitudinally upward. This causes the transmission plate to move the manhole cover on one side of the rubber plate out of the bottom mold. Then, motor A outside the operating table drives the double-acting screw to rotate through reducer A. Threaded blocks A and B outside the double-acting screw slide in the corresponding slots inside the operating table, causing them to move axially towards each other outside the double-acting screw. Threaded block A then drives drive rod A to move, and threaded block B drives drive rod B to move. This causes the blade inside drive rod A and the grinding block on drive rod B to contact the surface of the manhole cover, facilitating the removal and grinding of side scraps from manhole covers of different specifications, thus improving the processing efficiency of the manhole cover.

[0008] When the push rod moves the manhole cover out of the bottom mold, the rubber plate at the end of the push rod seals the top of the bottom mold, preventing the side scraps removed from the manhole cover from falling into the bottom mold and improving the processing quality of the manhole cover.

[0009] By adopting the above technical solution, the operating table is bolted to a fixed frame, and the fixed frame is bolted to a cylinder A. The cylinder A is bolted to a drive plate, the drive plate is bolted to a motor B, the motor B is flanged to the power output end, the reducer B is keyed to the inside of the reducer B, the reducer B is slidably connected to an outer rod, the outer rod is screwed to a damper at the height of the screw, and the bottom of the outer rod is bolted to a pressure mold.

[0010] When processing manhole covers, the manhole cover to be processed is first placed into the bottom mold in the operating table. Then, cylinder A in the fixed frame drives the drive plate to move, so that motor A below the drive plate drives the inner rod to move through reducer A. Then, the inner rod retracts inside the outer rod, and then the outer rod drives the bottom mold to move downward, so that the mold contacts the manhole cover in the bottom mold, thus facilitating the processing of the manhole cover.

[0011] By adopting the above technical solution, a damper is bolted inside the outer rod.

[0012] Specifically, when the inner rod retracts into the outer rod, the inner rod presses against the damper inside the outer rod. The contraction of the damper buffers the impact force, thus facilitating the protection of motor B.

[0013] By adopting the above technical solution, the inner side of the outer rod is symmetrically provided with limiting grooves to limit the movement of the inner rod.

[0014] Specifically, when the inner rod retracts into the outer rod, the inner rod slides within the limiting groove opened inside the outer rod. At the same time, the limiting groove limits the inner rod to prevent it from shifting.

[0015] By adopting the above technical solution, the input terminals of motor B, cylinder A, motor A, and cylinder B are all electrically connected to the power supply terminal of an external power source.

[0016] Specifically, by connecting to an external power source, the electrical equipment can operate normally, and all electrical equipment is controlled by a PLC controller.

[0017] The beneficial effects of this utility model are:

[0018] (1) The molding and pressing machine for manhole cover processing described in this utility model, after the manhole cover is processed, the cylinder B in the operating table drives the transmission plate to move, so that the transmission plate drives the top rod to move longitudinally upward, and then the transmission plate drives the manhole cover on the rubber plate side to move out of the bottom mold. Then the motor A outside the operating table drives the double screw to rotate through the reducer A. The threaded block A and the threaded block B move towards each other in the outer axis of the double screw. Then the threaded block A drives the drive rod A to move, and the threaded block B drives the drive rod B to move, so that the blade in the drive rod A and the grinding block on the drive rod B respectively contact the surface of the manhole cover, thereby facilitating the removal and grinding of the side scraps of manhole covers of different specifications, and improving the processing efficiency of manhole covers.

[0019] (2) The forming and pressing machine for manhole cover processing described in this utility model, when the top rod moves the manhole cover out of the bottom mold, the rubber plate at the end of the top rod seals the top of the bottom mold, so as to prevent the side scraps removed from the manhole cover from falling into the bottom mold and improve the processing quality of the manhole cover.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] To improve the processing efficiency of manhole covers, as one embodiment of this utility model, such as Figures 1 to 4 As shown, the manhole cover forming and pressing machine of this utility model includes an operating table 11. A bottom mold 5 for manhole cover processing is bolted inside the operating table 11. A top rod 25 is inserted into the bottom of the bottom mold 5. A transmission plate 26 is rotatably connected to the bottom of the top rod 25 via a bearing. A rubber plate 6 is screwed to the end of the top rod 25 away from the transmission plate 26. A power cylinder B24 is bolted to the bottom inner side of the operating table 11, and the power output end of the cylinder B24 is bolted to the bottom of the transmission plate 26. A power motor A8 is bolted to the outside of the operating table 11. A reducer A19 is connected to a flange on one side of machine A8. A double-acting lead screw 21 is connected to a key on one side of reducer A19. Threaded blocks A20 and B22 are externally threaded onto the double-acting lead screw 21. A drive rod A9 is welded to the outside of threaded block A20, and a drive rod B10 is welded to the outside of threaded block B22. A blade 7 for machining well covers is fixed to the outside of drive rod A9 with screws. A grinding block 27 for grinding well covers is fixed to the outside of drive rod B10 with screws. Support sleeves 23 are welded to the bottom of both drive rods A9 and B10, and a fixing rod 18 is slidably connected to the inside of the support sleeves 23.

[0028] During use, after the manhole cover is processed, the cylinder B24 inside the operating table 11 drives the transmission plate 26 to move, which in turn drives the top rod 25 to move longitudinally upward. This causes the transmission plate 26 to move the manhole cover on one side of the rubber plate 6 out of the bottom mold 5. Then, the motor A8 outside the operating table 11 drives the double-acting screw 21 to rotate through the reducer A19. The threaded blocks A20 and B22 outside the double-acting screw 21 slide in the grooves opened at corresponding positions inside the operating table 11, causing the threaded blocks A20 and B22 to move axially towards each other outside the double-acting screw 21. This causes the threaded block A20 to drive the drive rod A9 to move, and the threaded block B22 to drive the drive rod B10 to move. This causes the blade 7 inside the drive rod A9 and the grinding block 27 on the drive rod B10 to contact the surface of the manhole cover, which facilitates the removal and grinding of the side scraps of manhole covers of different specifications, thereby improving the processing efficiency of the manhole cover.

[0029] When the push rod 25 moves the manhole cover out of the bottom mold 5, the rubber plate 6 at the end of the push rod 25 seals the top of the bottom mold 5, preventing the side scraps removed from the manhole cover from falling into the bottom mold 5 and improving the processing quality of the manhole cover.

[0030] For example, in order to process manhole covers, such as... Figure 2 As shown, this utility model also includes a fixed frame 1 bolted to the outside of the operating table 11, and a cylinder A2 bolted to the inside of the fixed frame 1. A drive plate 3 is bolted to the end of the cylinder A2. A motor B12 is bolted to the inside of the drive plate 3. A reducer B13 is connected to the power output flange of the motor B12. An inner rod 14 is keyed to the inside of the reducer B13. An outer rod 16 is slidably connected to the outside of the inner rod 14. A damper 17 is installed at the height of the screw on the inside of the outer rod 16. A pressure mold 4 is bolted to the bottom of the outer rod 16.

[0031] When processing a manhole cover, the cover to be processed is first placed into the bottom mold 5 inside the operating table 11. Then, the cylinder A2 inside the fixing frame 1 drives the drive plate 3 to move, so that the motor A8 below the drive plate 3 drives the inner rod 14 to move through the reducer A19. Then, the inner rod 14 retracts inside the outer rod 16, and then the outer rod 16 drives the bottom pressing mold 4 to move downward, so that the pressing mold 4 contacts the manhole cover inside the bottom mold 5, thus facilitating the processing of the manhole cover.

[0032] To protect motor B12, for example, such as Figure 2 As shown, the present invention also includes a damper 17 bolted inside the outer rod 16.

[0033] When in use, when the inner rod 14 retracts into the outer rod 16, the inner rod 14 presses against the damper 17 inside the outer rod 16. The damper 17 retracts and buffers the impact force, thus facilitating the protection of the motor B12.

[0034] To prevent the inner rod 14 from shifting, for example, such as Figure 2 As shown, the present invention also includes a limiting groove 15 symmetrically provided on the inner side of the outer rod 16 to limit the inner rod 14.

[0035] When in use, as the inner rod 14 retracts into the outer rod 16, the inner rod 14 slides within the limiting groove 15 opened in the outer rod 16. At the same time, the limiting groove 15 limits the inner rod 14 to prevent it from shifting.

[0036] For electrical equipment to function properly, for example, such as Figures 1 to 4 As shown, this utility model also includes the fact that the input terminals of the motor B12, cylinder A2, motor A8, and cylinder B24 are all electrically connected to the power supply terminal of an external power source.

[0037] When in use, the electrical equipment works normally by connecting to an external power source, and all electrical equipment is controlled by the PLC controller.

[0038] In use, the manhole cover to be processed is first placed into the bottom mold 5 inside the operating table 11. Then, the cylinder A2 inside the fixing frame 1 drives the drive plate 3 to move, causing the motor A8 below the drive plate 3 to drive the inner rod 14 to move through the reducer A19. The inner rod 14 then retracts within the outer rod 16, and the outer rod 16 drives the bottom pressing mold 4 to move downwards, so that the pressing mold 4 contacts the manhole cover inside the bottom mold 5 for processing. After processing, the cylinder A2 inside the fixing frame 1 drives the drive plate 3 longitudinally upwards, causing the pressing mold 4 to separate from the manhole cover. Then, cylinder B24 in the operating table 11 drives the transmission plate 26 to move, causing the transmission plate 26 to drive the push rod 25 to move longitudinally upward. The push rod 25 is installed in the bearing seat of the transmission plate 26 through a deep groove ball bearing, and the bearing seat is welded to the inner wall of the transmission plate 26. Then, the transmission plate 26 drives the manhole cover on one side of the rubber plate 6 to move out of the bottom mold 5. Subsequently, cylinder A2 drives the drive plate 3 longitudinally downward, so that the pressing mold 4 contacts the manhole cover, so that the manhole cover is fixed between the pressing mold 4 and the push rod 25. Then, the motor B12 in the drive plate 3 drives the inner rod through the reducer B13. Rotation of rod 14 causes the inner rod 14 to drive the mold 4 to rotate via the outer rod 16. Simultaneously, the push rod 25 rotates within the transmission plate 26, causing the push rod 25 and the manhole cover within the mold 4 to rotate. Motor A8 outside the operating platform 11 drives the bidirectional lead screw 21 to rotate via reducer A19. The bidirectional lead screw 21 is mounted in the bearing seat of the operating platform 11 via a deep groove ball bearing. The bearing seat is welded to the inner wall of the operating platform 11. Threaded blocks A20 and B22 outside the bidirectional lead screw 21 slide within corresponding slots in the operating platform 11, allowing the threaded blocks A20 and B22 to slide. Block B22 moves axially towards each other on the outer side of the double-acting screw 21, which in turn drives the drive rod A9 to move. The threaded block B22 drives the drive rod B10 to move, so that the blade 7 in the drive rod A9 and the grinding block 27 on the drive rod B10 come into contact with the surface of the manhole cover. This facilitates the removal and grinding of the side scraps of manhole covers of different specifications, improving the processing efficiency of the manhole cover. At the same time, the rubber plate 6 at the end of the top rod 25 seals the top of the bottom mold 5, preventing the side scraps removed from the manhole cover from falling into the bottom mold 5, thus improving the processing quality of the subsequent manhole cover.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
