Description

Technical Field

[0001] This invention relates to the field of paper gating pipe manufacturing technology, specifically to a paper gating pipe equipment and process for casting. Background Technology

[0002] Paper gating pipes, also known as paper gate pipes or paper casting pipes, are hollow paper pipes used in casting production to transport molten metals such as iron, steel, and aluminum. The manufacturing process of paper gating pipes involves using special paper, cardboard, and adhesives as raw materials, and going through processes such as rolling, forming, drying, cutting, and coating to mass-produce these high-temperature resistant paper pipes.

[0003] In the existing technology for manufacturing paper gating tubes, the inner diameter, wall thickness, outer diameter, and length of the paper gating tube are determined by the forming mold, mandrel, and die head of the tube rolling machine. Paper gating tubes produced by the same set of molds have completely consistent diameters, wall thicknesses, and lengths. However, customers require paper gating tubes with completely different lengths. When cutting paper gating tubes with a traditional cutter, the cutting stroke is fixed, making it impossible to achieve equidistant cutting. The position of the paper gating tube relative to the cutter needs to be repeatedly adjusted to achieve fixed-distance cutting, making the cutting of paper gating tubes inconvenient. At the same time, after cutting, the tube ends are uneven, which can easily lead to burrs, chipping and peeling of the refractory coating, etc. Burrs and detached powder from the paper gating tube ends after processing can easily enter the casting cavity with the molten metal, causing slag inclusions and porosity defects in the casting, affecting the stability of the casting gating system, thus making the use of the equipment inconvenient.

[0004] Therefore, there is a need for a paper gating tube equipment for casting to solve the problems in the existing paper gating tube processing device that cannot perform equidistant cutting of paper gating tubes and that the unevenness of the tube opening after cutting affects the stability of the casting gating system.

[0012] A further improvement of the technical solution of the present invention is that: the cutting assembly further includes a second spring telescopic rod and a capacitive thickness sensor, the capacitive thickness sensor is located on one side of the cutting blade, the second spring telescopic rod is fixed on one side of the blade holder, and one end of the second spring telescopic rod is fixed to the surface of the capacitive thickness sensor.

[0013] A further improvement of the technical solution of the present invention is that: the cutting processing mechanism further includes a grinding component, the grinding component includes a storage slot, a movable seat, a positioning shaft, a support plate, a connecting slot, and a connecting strip. The storage slot is located on the other side of the top of the workbench. The movable seat is slidably inserted into the inner cavity of the storage slot. The positioning shaft is slidably inserted through both sides of the movable seat. Both sides of the positioning shaft are fixed to the inner wall of the movable seat.

One end of the top of the connecting strip is fixed to the surface of the bottom of the movable seat, and the other end of the top of the connecting strip is fixed to the surface of the bottom of the slide.

[0014] A further improvement of the technical solution of the present invention is that: the grinding assembly further includes a second threaded rod, a support rod, a connecting seat, a third motor, a roller seat, a grinding roller, and a movable shaft.

The movable shaft is rotatably connected to the top of the roller seat, and the grinding roller is fixedly sleeved on the outer circumferential surface of the movable shaft.

[0015] A process for producing paper gating pipes for casting includes the following steps:

[0016] S1: The paper sprue tube body formed from the mold is clamped and positioned through the output end of the hollow rotating gripper;

[0017] S2: Adjust the grinding roller to fit the surface of the paper sprue tube body. Adjust the distance between the contact shaft and the center of the rotating disk according to the cutting length of the paper sprue tube required by the customer. The contact plate is positioned by the magnetic attraction generated by the electromagnetic block and the magnetic rod.

[0018] S3: Make the grinding roller rotate on its own axis and make a circular motion around the opening of the paper sprue tube body to grind the initial opening of the paper sprue tube body.

[0019] S4: Start the motor to make the contact shaft move in a circular motion. The contact plate applies a reaction force to the contact block, causing the slide to slide a set distance along the guide rail. Simultaneously, the cutting component and the grinding component move the same distance along with the slide, completing one fixed-distance movement.

[0020] S5: After the fixed-distance movement, the capacitive thickness sensor first contacts the surface of the paper sprue pipe body to detect the wall thickness of the paper sprue pipe body, and transmits the thickness data to the external controller to adjust the hydraulic cylinder to control the cutting depth of the cutting blade.

[0021] S6: Start motor 2 and hollow rotating gripper to make the cutting blade make a circular cut on the paper gating pipe body. After the cutting is completed, turn off motor 2, hydraulic cylinder and hollow rotating gripper.

[0022] S7: After cutting, the cut pipe opening is polished again by the polishing roller, and the above steps are repeated to complete the fixed-distance cutting and pipe opening polishing of multiple sections of paper gating pipe, thus completing a single batch processing.

[0023] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0024] 1. This invention, through a movable component, enables the slide to slide intermittently along the surface of the guide rail by the same distance. This allows the cutting component to perform fixed-distance cutting of the paper sprue tube body according to customer requirements, enabling the paper sprue tube body to be cut into multiple paper sprue tube bodies of the same length and size as required by the customer. This improves the applicability of the device and makes it easy to operate, increasing the efficiency of cutting and processing the paper sprue tube body and shortening the time for fixed-distance cutting, thereby improving the ease of use of the device.

[0025] 2. The present invention, through the cutting component, allows for easy adjustment of the cutting blade to automatically move away from the paper sprue body as the sliding block moves horizontally, thereby preventing damage to the outer circumferential surface of the paper sprue body due to friction caused by direct sliding of the cutting blade. After the sliding block moves, the cutting blade automatically adheres to the required cutting position on the outer circumferential surface of the paper sprue body. At the same time, it can control the cutting depth of the cutting blade for paper sprue bodies of different thicknesses to improve the quality of cutting the paper sprue body, thereby further improving the applicability of the device.

[0026] 3. The present invention, through the grinding component, can grind the opening of the paper gating tube body before each cutting of a section of the paper gating tube body, thereby ensuring that the opening of the paper gating tube body will not be uneven and prone to burrs. This avoids the situation where burrs and detached powder from the paper gating tube opening after processing can easily enter the mold cavity with the molten metal, causing slag inclusions and porosity defects in the casting. This helps to ensure the stability of the casting gating system, thereby further improving the applicability of the device. Attached Figure Description

[0038] The present invention will be further described in detail below with reference to embodiments:

[0039] Example 1, First aspect, such as Figure 1 - Figure 10 As shown, the present invention provides a paper gating tube device for casting, including a workbench 1, a mounting base 2 fixed on one side of the top of the workbench 1, a hollow rotating gripper 3 fixed on one side of the mounting base 2, the output end of the hollow rotating gripper 3 being rotatably connected to the inner wall of the mounting base 2 through the gating base 2, a paper gating tube body 4 fixed on one side of the hollow rotating gripper 3, and a cutting processing mechanism connected to both ends of the paper gating tube body 4 at the top of the workbench 1.

[0040] The cutting mechanism includes a cutting component and a moving component located at one end of the paper gating tube body 4. The moving component includes a guide rail 5, a slide 6, a mounting frame 8, a motor 9, a rotating disk 10, and a distance fixing component. The guide rail 5 is fixed at one end of the top surface of the worktable 1. The slide 6 is slidably fitted onto the surface of the guide rail 5. The mounting frame 8 is fixed at the top surface of the slide 6. The motor 9 is fixed at the top of the slide 6 at the middle position of the mounting frame 8. The output end of the motor 9 is rotatably connected to the inner wall of the mounting frame 8. The rotating disk 10 is located at the top of the mounting frame 8, and its bottom surface is fixed to the output end of the motor 9 at the middle position. The distance fixing component is connected to the mounting frame 8 and the rotating disk 10.

[0041] When it is necessary to cut the paper sprue tube body 4 formed from the mold at a fixed distance according to the customer's required size, the paper sprue tube body 4 can be clamped and fixed by one side of the hollow rotating jaw 3, and the rotating disk 10 can be rotated by starting the motor 9, so that the fixed distance component can make the slide 6 intermittently slide along the surface of the guide rail 5 by the same distance. Thus, when the cutting component cuts the paper sprue tube body 4, it can realize the fixed distance cutting operation of the paper sprue tube body 4 according to the customer's requirements, so that the paper sprue tube body 4 can be cut into multiple paper sprue tube bodies 4 with the same length and size as required by the customer.

[0042] The distance-fixing component includes a sleeve frame 11, a rod groove 14, a threaded rod 15, a threaded sleeve 16, an abutment shaft 17, and an abutment block 18. The sleeve frame 11 is fitted onto the top surface of the rotating disk 10. The rod groove 14 is located at the bottom of the sleeve frame 11 on the rotating disk 10. The threaded rod 15 is rotatably connected to the inner wall of the rod groove 14. The threaded sleeve 16 is threadedly connected to the outer circumferential surface of the threaded rod 15. The abutment shaft 17 is fixed at the top of the threaded sleeve 16. The abutment shaft 17 is slidably inserted into the inner wall of the sleeve frame 11. The abutment block 18 is fixed at one end of the sleeve frame 11. The sleeve frame 11 is slidably inserted into the top surface of the mounting bracket 8.

[0043] When the threaded rod 15 is rotated, the inner wall of the groove 14 can act as a stop and limit against the threaded sleeve 16. Under the cooperation of the threaded structure between the threaded sleeve 16 and the inner wall of the threaded rod 15, the threaded sleeve 16 can move horizontally towards or away from the center of the rotating disk 10, thereby adjusting the distance between the abutting shaft 17 and the center of the rotating disk 10. When the rotating disk 10 rotates, the abutting shaft 17 can make a circular motion. As the abutting shaft 17 abuts against the inner wall of the sleeve frame 11, and under the limiting effect of the mounting bracket 8 on the sleeve frame 11, the sleeve frame 11 can reciprocate in a direction parallel to the axis of the paper sprue tube body 4, thereby driving the abutting block 18 to reciprocate in a direction parallel to the axis of the paper sprue tube body 4.

[0044] The distance-fixing component also includes a shaft groove 7, a motion seat 19, a contact plate 20, a mounting plate 21, a spring telescopic rod 22, a magnetic rod 23, and an electromagnetic block 24. The shaft groove 7 is located on the top of the workbench 1, on one side of the guide rail 5. The motion seat 19 is slidably inserted into the inner cavity of the shaft groove 7. The magnetic rod 23 passes through the middle of the motion seat 19 and is fixed to both sides of the inner wall of the shaft groove 7. Two electromagnetic blocks 24 are symmetrically fixed to the inner wall of the motion seat 19 at both ends of the magnetic rod 23. The two electromagnetic blocks 24 are in contact with the outer circumferential surface of the magnetic rod 23. The contact plate 20 is fixed to the top surface of the motion seat 19. The mounting plate 21 is fixed to one side of the mounting frame 8. The spring telescopic rod 22 is fixed to the surface of the mounting plate 21. The side of the spring telescopic rod 22 away from the mounting plate 21 is fixed to the surface of the contact plate 20.

[0045] When the motor 19 is started, the contact shaft 17 needs to rotate clockwise to ensure that it rotates clockwise. During this process, the contact block 18 reciprocates along the axis parallel to the center line of the paper gating tube body 4. When the position of the slide 6 needs to be adjusted to change the cutting position, the electromagnetic block 24 is energized so that it can magnetically attract and position itself with the magnetic rod 23. This allows the moving seat 19 and the contact plate 20 to be restricted by the magnetic action of the magnetic rod 23 and the electromagnetic block 24, preventing them from moving. When the sleeve 11 moves to the center of the top of the rotating disk 10... When in position, the abutment block 18 will abut against the surface of the abutment plate 20. When the sleeve frame 11 moves to the other side of the top of the rotating disk 10, it can apply a force to the slide block 6 under the action of the abutment block 18 and the abutment plate 20, so that it can slide a certain distance along the surface of the guide rail 5. The sliding distance is related to the distance between the threaded sleeve 16 and the center position of the rotating disk 10. By adjusting the distance between the threaded sleeve 16 and the center position of the rotating disk 10, the position range of the reciprocating motion of the sleeve frame 11 can be adjusted, thereby adjusting the single displacement range of the slide block 6 under the action of the abutment block 18 and the abutment plate 20.

[0046] When the slide block 6 can slide a certain distance, it can drive the mounting plate 21 to slide a certain distance in the horizontal direction, causing the spring telescopic rod 22 to deform. After the slide block 6 has completed its displacement, the electromagnetic block 24 is de-energized, so that there is no longer a magnetic attraction between the electromagnetic block 24 and the magnetic rod 23. Thus, under the action of the spring telescopic rod 22's rebound force, the moving seat 19 can slide along the outer circumference of the magnetic rod 23 to the position where the spring telescopic rod 22 can return to its original length. After the sleeve frame 11 moves back and forth in the horizontal direction, the slide block 6 will move again by the same range under the action of the contact block 18 and the contact plate 20. Thus, the single displacement range of the slide block 6 can be adjusted according to customer needs, so that the cutting component can cut a batch of paper sprue tube bodies 4 of different lengths at a fixed distance. This improves the applicability of the device and makes it easy to operate, which can improve the efficiency of cutting and processing the paper sprue tube bodies 4 and shorten the time for fixed-distance cutting of the paper sprue tube bodies 4, thereby improving the ease of use of the device.

[0047] In Example 2, the second aspect is that the cutting assembly includes an abutment shell 12, a connecting strip 13, a limiting seat 25, a blade holder 26, a second motor 27, a cutting blade 28, and a hydraulic cylinder 29. The abutment shell 12 is located at the top of the sleeve frame 11. The connecting strip 13 is fixed at the top of the abutment shell 12. The limiting seat 25 is fixed on both sides of the mounting bracket 8 at the bottom of the rotating disk 10. The abutment shell 12 and the top surface of the limiting seat 25 are slidably inserted and connected. The hydraulic cylinder 29 is fixed in the inner cavity at one end of the connecting strip 13. The blade holder 26 is fixed on the surface of one end of the output end of the hydraulic cylinder 29. The second motor 27 is fixed on the surface of the blade holder 26, and its output end is rotatably connected to the inner wall of the blade holder 26. The cutting blade 28 is fixedly sleeved on the outer peripheral surface of the output end of the second motor 27.

[0048] When the sleeve frame 11 moves horizontally from a position close to the mounting plate 21 to a position away from the mounting plate 21, the sliding block 6 is positioned at a certain distance due to the contact between the contact block 18 and the contact plate 20. This allows the connecting strip 13 and the cutting blade 28 to be displaced a certain distance. When the sleeve frame 11 moves from a position away from the mounting plate 21 to a position close to the mounting plate 21, the contact block 18 can separate from the contact plate 20. Furthermore, under the contact between the contact shaft 17 and the inner wall of the contact shell 12, it abuts against the limiting seat 25. Under the limiting action of the contact shell 12, the contact shell 12 can drive the connecting strip 13 to move closer to the paper sprue tube body 4 until the cutting blade 28 adheres to the inner wall of the motor 27. By starting the motor 27, the cutting blade 28 can rotate, thereby allowing the cutting blade 28 to apply a cutting force to the paper sprue tube body 4. By activating the hollow rotating gripper 3, the paper sprue tube body 4 can be rotated and subjected to the cutting action of the cutting blade 28, thus completing the cutting action of the paper sprue tube body 4.

[0049] The cutting assembly also includes a spring telescopic rod 30 and a capacitive thickness sensor 31. The capacitive thickness sensor 31 is located on one side of the cutting blade 28, and the spring telescopic rod 30 is fixed on one side of the blade holder 26. One end of the spring telescopic rod 30 is fixed to the surface of the capacitive thickness sensor 31.

[0050] When the cutter head 26 moves towards the paper sprue tube body 4, the capacitive thickness sensor 31 first contacts the surface of the paper sprue tube body 4. After the cutting blade 28 contacts the surface of the paper sprue tube body 4, the capacitive thickness sensor 31, under the resistance of the paper sprue tube body 4, causes the spring telescopic rod 30 to deform. Under the rebound force of the spring telescopic rod 30, the capacitive thickness sensor 31 is pressed tightly against the outer circumference of the paper sprue tube body 4. The thickness of the paper sprue tube body 4 can be detected by the capacitive thickness sensor 31. The capacitive thickness sensor 31 can transmit the thickness dimension of the paper sprue tube body 4 to an external controller, and based on the thickness of the paper sprue tube body 4... The extension length of the output end of the size control hydraulic cylinder 29 is adjusted so that the cutting blade 28 can automatically move away from the paper sprue tube body 4 when it moves horizontally with the slide 6, thus preventing damage to the outer circumference of the paper sprue tube body 4 due to friction caused by direct sliding of the cutting blade 28. After the slide 6 is displaced, the cutting blade 28 automatically fits against the outer circumference of the paper sprue tube body 4 at the required cutting position, thereby further improving the ease of use of the device. At the same time, after the slide 6 is displaced within a set range, the cutting blade 28 can control the cutting depth of the cutting blade 28 according to the paper sprue tube body 4 of different thicknesses to improve the quality of cutting the paper sprue tube body 4, thereby further improving the applicability of the device.

[0051] In embodiment 3, the third aspect, the cutting processing mechanism further includes a grinding assembly, which includes a storage slot 32, a movable seat 33, a positioning shaft 34, a support plate 35, a connecting slot 47, and a connecting strip 48. The storage slot 32 is located on the other side of the top of the workbench 1. The movable seat 33 is slidably inserted into the inner cavity of the storage slot 32. The positioning shaft 34 is slidably inserted through and into both sides of the movable seat 33. Both sides of the positioning shaft 34 are fixed to the inner wall of the movable seat 33. The support plate 35 is fixed to the top of the movable seat 33. The connecting slot 47 is located at the bottom of the storage slot 32 and the slide 6. The connecting strip 48 is slidably inserted into the middle of the two limiting ring grooves 46. One end of the top of the connecting strip 48 is fixed to the surface of the bottom of the movable seat 33, and the other end of the top of the connecting strip 48 is fixed to the surface of the bottom of the slide 6.

[0052] The movable seat 33 is located in the inner cavity of the storage slot 32 and can only slide along the outer circumferential surface of the positioning shaft 34, so that the movable seat 33 and the support plate 35 can slide smoothly in the horizontal direction. Due to the connecting action of the connecting strip 48, after the slide 6 slides a certain range, the movable seat 33 can slide a range of the same length as the slide 6 each time.

[0053] The grinding assembly also includes a threaded rod 36, a support rod 37, a connecting seat 38, a motor 39, a roller seat 40, a grinding roller 41, and a movable shaft 42. The threaded rod 36 is threadedly connected to one side of the support plate 35, and the support rod 37 is slidably inserted into the other side of the support plate 35. The connecting seat 38 is located on one side of the threaded rod 36 and the support rod 37, and the surfaces of the threaded rod 36 and the connecting seat 38 are rotatably connected. One side of the support rod 37 is fixed to the surface of the connecting seat 38. The motor 39 is fixed to one side of the connecting seat 38, and the output end of the motor 39 is rotatably connected to the surface of the connecting seat 38. The roller seat 40 is fixedly sleeved on the outer circumferential surface of the output end of the motor 39. The movable shaft 42 is rotatably connected to the top of the roller seat 40, and the grinding roller 41 is fixedly sleeved on the outer circumferential surface of the movable shaft 42.

[0054] Due to the limiting action of the contact between the support rod 37 and the support plate 35, the connecting seat 38 can only slide in the horizontal direction. By rotating the threaded rod 36, the position of the connecting seat 38 in the horizontal direction can be adjusted under the cooperation of the threaded structure of the support plate 35. This allows the connecting seat 38 to move closer to the paper sprue tube body 4 when the cutting blade 28 is positioned at the position of the first cut on the outer circumference of the paper sprue tube body 4, by rotating the threaded rod 36, until the grinding roller 41 is in contact with the tube opening of the paper sprue tube body 4. Before cutting, the motor 39 can be started to make the roller seat 40 rotate, so that the grinding roller 41 can be in contact with the tube opening of the paper sprue tube body 4 and rotate to grind the tube opening of the paper sprue tube body 4.

[0055] The grinding assembly also includes a worm 43, a worm wheel 44, a limiting ring groove 46, and a limiting block 45. The worm 43 is fixed at one end of the motor 39. The worm wheel 44 is fixedly sleeved on the outer circumferential surface of the worm 43. The worm wheel 44 and the movable shaft 42 are meshed together. The limiting ring groove 46 is opened on the side of the connecting seat 38 near the roller seat 40. The limiting block 45 is slidably inserted into the inner cavity of the limiting ring groove 46 and fixed to the surface of the roller seat 40.

[0056] When the motor 39 is started, the worm 43 is in a rotating state. Under the meshing action of the worm 43 and the worm wheel 44, the movable shaft 42 is in a rotating state. This causes the grinding roller 41 to rotate while making a circular motion. Under the friction between the grinding roller 41 and the opening of the paper gating tube body 4, the opening of the paper gating tube body 4 is ground. The opening of the paper gating tube body 4 is ground before each section is cut, which ensures that the opening of the paper gating tube body 4 will not be uneven and prone to burrs. This avoids the burrs and detached powder from the paper gating tube opening after processing from easily entering the mold cavity with the molten metal, causing slag inclusions and porosity defects in the casting. This helps to ensure the stability of the casting gating system and further improves the applicability of the device.

[0057] A process for producing paper gating pipes for casting includes the following steps:

[0058] S1: The paper sprue tube body 4 formed from the mold is clamped and positioned through the output end of the hollow rotating gripper 3.

[0059] S2: Adjust the grinding roller 41 to fit against the surface of the paper sprue tube body 4. Adjust the distance between the contact shaft 17 and the center of the rotating disk 10 according to the cutting length of the paper sprue tube required by the customer. The contact plate 20 is positioned by the magnetic attraction between the electromagnetic block 24 and the magnetic rod 23.

[0060] S3: The grinding roller 41 rotates while making a circular motion around the opening of the paper sprue tube body 4 to grind the initial opening of the paper sprue tube body 4.

[0061] S4: Start motor 9 to make the contact shaft 17 move in a circle. The contact plate 20 applies a reaction force to the contact block 18, causing the slide 6 to slide a set distance along the guide rail 5. Simultaneously, the cutting component and the grinding component move the same distance along with the slide 6, completing one fixed-distance movement.

[0062] S5: After the fixed-distance movement, the capacitive thickness sensor 31 first contacts the surface of the paper sprue tube body 4 to detect the wall thickness of the paper sprue tube body 4, and transmits the thickness data to the external controller to adjust the hydraulic cylinder 29 to control the cutting depth of the cutting blade 28.

[0063] S6: Start motor 27 and hollow rotating gripper 3 to make the cutting blade 28 perform a circular cut on the paper gating tube body 4. After the cut is completed, turn off motor 27, hydraulic cylinder 29 and hollow rotating gripper 3.

[0064] S7: After cutting, the cut pipe opening is polished again by the polishing roller 41, and the above steps are repeated to complete the fixed-distance cutting and pipe opening polishing of multiple sections of paper gating pipe, thus completing a single batch processing.
