Abstract
Description
Technical Field
[0001] This utility model relates to the field of corrugated pipe processing technology, specifically a corrugated pipe raw material cylinder grinding mechanism. Background Technology
[0002] Corrugated pipe is a type of pipe with a corrugated shape. Metal corrugated pipe has high strength and is suitable for some applications with high pressure and temperature requirements. The raw material cylinder of corrugated pipe is the metal pipe before it is processed and formed. Its surface is smooth and flat, and it needs to be cut into sections according to the length of the corrugated pipe to be produced.
[0003] After the corrugated pipe's raw material cylinder is cut, its ends often have burrs and sharp edges, so it needs to be polished to keep it flat and smooth for subsequent connection. However, the raw material cylinder is often accompanied by flying debris during polishing, which can scratch the workers and is not convenient for subsequent cleaning and collection. In addition, some existing polishing mechanisms require the raw material cylinder to be manually held close to the polishing mechanism for processing. When polishing the other end, the position of the raw material cylinder needs to be manually adjusted, which is very inconvenient.
[0004] In order to avoid the flying debris during the grinding of the corrugated pipe material cylinder, which is difficult to collect, and to eliminate the need for manual holding of the material cylinder during grinding, this application proposes a grinding mechanism for the corrugated pipe material cylinder. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a corrugated pipe raw material cylinder grinding mechanism that simultaneously grinds both ends of the raw material cylinder, while the debris generated during grinding is limited by the shielding box to reduce the range of its splashing.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrugated pipe raw material cylinder grinding mechanism, including a worktable, with shielding boxes provided on both the left and right sides of the top of the worktable. Silicone sheets are fixedly connected to the inner walls of the opposite ends of the shielding boxes. Motors are fixedly connected to the middle of the opposite ends of the shielding boxes. The driving end of the motor passes through the inner wall of the shielding box and is fixedly connected to a sleeve. Sliding bolts are slidably connected to the inner walls of the opposite ends of the sleeves. Grinding discs are fixedly connected to the opposite ends of the sliding bolts. A clamping platform is fixedly connected to the middle of the top of the worktable. Cylinders are fixedly connected to the inner walls of the front and rear sides of the top of the clamping platform. Clamping blocks are fixedly connected to the driving ends of the cylinders.
[0007] Further description: A collection box is fixedly connected to the rear end of the workbench. A negative pressure fan is fixedly connected to the inner wall of the bottom middle of the collection box and runs through both the inner and outer sides of the collection box. An interception box is provided on the inner wall of both the left and right sides of the negative pressure fan at the top of the collection box. Here, the negative pressure fan is an existing technology device with the bottom as the air outlet and the top as the air intake, which can generate strong negative pressure airflow.
[0008] Further description: Each of the top inner walls of the shielding box is fixedly connected to an air inlet cylinder, which extends through both the inner and outer sides of the shielding box. Each air inlet cylinder is fixedly connected to a diffuser hood at its bottom. Here, the bottom of the air inlet cylinder is open, the inner wall is hollow, and the diffuser hood guides the airflow and expands the range.
[0009] Further description: The inner walls of both the left and right ends of the collection box are slidably connected with air guide pipes, and one end of each air guide pipe is fixedly connected to the upper rear end of the air inlet cylinder; here, the air guide pipes are bent in multiple places, and the bending angle is 90°.
[0010] Further description: Electric push rods are installed on both the left and right sides of the top of the workbench at the rear of the shielding box. The drive end of each electric push rod is fixedly connected to a traction frame. The front end of each traction frame is fixedly connected to the lower part of the rear end of the shielding box on the opposite side. Here, the electric push rods are existing technology and are used to push objects to move along a straight path.
[0011] Further description: The top of the workbench has sliding grooves in the middle of the left and right sides, and the bottom of the shielding box is fixedly connected to a movable block. The outer wall of the movable block is slidably connected to the inner wall of the sliding groove. Here, the movable block and the sliding groove work together to provide the running trajectory for the shielding box.
[0012] Further description: Each sleeve has a pressure sensor fixedly connected to the inner wall of the opposite end, and each sleeve has a spring fixedly connected to the opposite end of the sliding bolt. The other end of each spring is fixedly connected to the opposite end of the grinding disc. Here, the spring generates elastic potential energy after being compressed, which will drive the grinding disc to reset.
[0013] Further description: The opposite ends of the clamping blocks are all arc-shaped, and the opposite ends of the clamping blocks are all diagonal; here, the opposite ends of the clamping blocks are diagonal, which can prevent the raw material cylinder from shifting vertically when clamping it.
[0014] Beneficial effects:
[0015] 1. In this utility model, the corrugated pipe raw material cylinder is clamped and fixed by the cooperation of the clamping table, cylinder, and clamping block, eliminating the need for manual holding during grinding. Then, with the cooperation of the electric push rod, traction frame, shielding box, sliding groove, and movable block, the shielding boxes on both sides move towards both ends of the raw material cylinder. Then, with the cooperation of the shielding box, silicone sheet, motor, sleeve, sliding bolt, and grinding disc, the two ends of the raw material cylinder are ground synchronously. The debris generated during grinding is limited by the shielding box, which reduces the range of its splash, making it easier to collect and clean. Furthermore, the shielding box prevents debris from splashing into the working environment and accidentally injuring nearby workers.
[0016] 2. In this utility model, through the cooperation of sleeve, sliding bolt, spring, and pressure sensor, the grinding disc continues to abut against one end of the raw material cylinder under the continuous push of the electric push rod. Under the reaction force, the sliding bolt touches the pressure sensor, causing it to generate an electrical signal that is transmitted to the control platform, which then controls the electric push rod on that side to stop running. This avoids the gap between the grinding disc and one end of the raw material cylinder and ensures a close fit. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] Please see Figure 1 , Figure 3 as well as Figure 4 - Figure 6 A corrugated pipe raw material cylinder grinding mechanism includes a worktable 1. A shielding box 4 is provided on both the left and right sides of the top of the worktable 1. A silicone sheet 14 is fixedly connected to the inner wall of the middle of opposite ends of each shielding box 4. Electric push rods 7 are installed on both the left and right sides of the top of the worktable 1 at the rear of the shielding boxes 4. A traction frame 8 is fixedly connected to the drive end of each electric push rod 7. The front ends of the traction frames 8 are fixedly connected to the lower part of the rear ends of the shielding boxes 4 on opposite sides. Sliding grooves 9 are provided in the middle of both the left and right sides of the top of the worktable 1. Movable blocks 10 are fixedly connected to the bottom of each shielding box 4. The outer walls of the movable blocks 10 are... A motor 16 is fixedly connected to the inner wall of the sliding groove 9 and the middle of the opposite end of the shielding box 4. The driving end of the motor 16 passes through the inner wall of the shielding box 4 and is fixedly connected to the sleeve 17. The inner wall of the opposite end of the sleeve 17 is slidably connected to the sliding bolt 18. The opposite end of the sliding bolt 18 is fixedly connected to the grinding disc 15. The top center of the worktable 1 is fixedly connected to the clamping table 3. The inner walls of the front and rear sides of the top of the clamping table 3 are fixedly connected to the cylinder 11. The driving end of the cylinder 11 is fixedly connected to the clamping block 12. The opposite end of the clamping block 12 is arc-shaped and the opposite end of the clamping block 12 is diagonal.
[0028] To further explain, before grinding the raw material cylinder, the raw material cylinder needs to be placed between the two clamping blocks 12. Then, the two cylinders 11 are started, and the driving end of the cylinder 11 begins to push the clamping block 12 to move in the opposite direction, thereby achieving a stable clamping of the raw material cylinder. Next, the two electric push rods 7 are operated, and their driving ends push the traction frame 8, which drives the shielding box 4 to move in the opposite direction. During this process, the movable block 10 at the bottom of the shielding box 4 will slide smoothly along the inner wall of the sliding groove 9. Then, both ends of the raw material cylinder will pass through the silicone sheets 14 on both sides. The silicone sheets 14 are elastic. When the raw material cylinder passes through, it will open the inner edge of the silicone sheet 14. Then, the inner edge of the silicone sheet 14 will fit against the outer wall of the raw material cylinder until one end of the raw material cylinder abuts against the grinding disc 15 on the corresponding side.
[0029] By starting the motors 16 on both sides, their drive ends drive the grinding disc 15 to rotate through the sleeve 17 and the sliding bolt 18, thereby grinding one end of the attached raw material cylinder. The debris generated during the grinding process will be confined within the range of the grinding disc 15 and scattered, effectively reducing the range of debris splashing.
[0030] Example 2
[0031] Please see Figure 2 , Figure 7Further, based on the first embodiment, a collection box 2 is fixedly connected to the rear end of the workbench 1. A negative pressure fan 22 is fixedly connected to the inner wall of the middle part of the bottom of the collection box 2 and runs through both the inner and outer sides of the collection box 2. An interception box 21 is provided on the inner wall of both the left and right sides of the negative pressure fan 22 at the top of the collection box 2. An air inlet 5 is fixedly connected to the inner wall of the top of the shielding box 4 and runs through both the inner and outer sides of the shielding box 4. A diffuser hood 13 is fixedly connected to the bottom of the air inlet 5. Air guide pipes 6 are slidably connected to the inner walls of both the left and right ends of the collection box 2. One end of the air guide pipe 6 is fixedly connected to the upper side of the rear end of the air inlet 5. A touch pressure sensor 20 is fixedly connected to the inner wall of the opposite end of the sleeve 17. A spring 19 is fixedly connected to the opposite end of the sleeve 17 located outside the sliding bolt 18. The other end of the spring 19 is fixedly connected to the opposite end of the grinding disc 15.
[0032] To further explain, when the raw material cylinder is clamped, it is placed manually, so it is difficult to ensure that the distances from both ends of the raw material cylinder to the center of the cylinder are consistent. However, when the electric push rod 7 pushes the grinding disc 15 against one end of the raw material cylinder, the resulting reaction force will cause the grinding disc 15 to drive the sliding bolt 18 to slide into the sleeve 17, while squeezing the spring 19, until the sliding bolt 18 reaches the end of the inner wall of the sleeve 17 and touches the pressure sensor 20. After the pressure sensor 20 is subjected to external force, it will generate an electrical signal and transmit it to the control platform. According to the preset program logic, the control platform will control the electric push rod 7 on that side to stop running. In this way, it can be ensured that the grinding disc 15 is tightly fitted to one end of the raw material cylinder, avoiding gaps.
[0033] When the shielding boxes 4 on both sides move towards the two ends of the raw material cylinder, the air guide pipes 6 will also move accordingly and slide inward on the inner walls of the two ends of the collection box 2. When the grinding disc 15 grinds the two ends of the raw material cylinder, the negative pressure fan 22 is started to form a negative pressure airflow in the collection box 2. The negative pressure airflow passes through the filter part of the interception box 21 and is then extended by the air guide pipes 6, so that the negative pressure airflow is distributed at the diffuser 13, sucking in the debris generated by grinding the raw material cylinder. The debris will move along the negative pressure airflow to the interception box 21 and be intercepted by the filter of the interception box 21. After the grinding is completed, the power of the negative pressure fan 22 is turned off, and then the interception box 21 is pulled out from the collection box 2 to clean up the intercepted debris.
[0034] Working principle: First, the raw material cylinder is placed between the two clamping blocks 12. Then, the two cylinders 11 are activated, causing the driving ends of the cylinders 11 to push the clamping blocks 12 to move in opposite directions and clamp the raw material cylinder. Next, the two electric push rods 7 are operated, causing their driving ends to push the traction frame 8 and move the shielding box 4 in opposite directions. The movable block 10 at the bottom of the shielding box 4 slides on the inner wall of the sliding groove 9. At the same time, as the two shielding boxes 4 move towards the two ends of the raw material cylinder respectively, the air guide pipe 6 will also be displaced. The material cylinder slides inward along the inner walls of both ends of the collection box 2, while the two ends of the material cylinder pass through the silicone sheets 14 on both sides until one end of the material cylinder abuts against the corresponding grinding disc 15. Under the continuous push of the electric push rod 7, the grinding disc 15 continues to abut against one end of the material cylinder, and under the reaction force, the grinding disc 15 drives the sliding bolt 18 to slide into the sleeve 17, while compressing the spring 19, until the sliding bolt 18 reaches the end of the inner wall of the sleeve 17 and touches the pressure sensor 20. At this time, the pressure sensor 20 is subjected to external force and will generate The generated electrical signal is transmitted to the control platform. According to the program logic, the control platform controls the electric push rod 7 on that side to stop running. In this way, the gap between the grinding disc 15 and one end of the raw material cylinder can be avoided, and they can be kept in close contact. Then, the motors 16 on both sides are started, and their drive ends drive the grinding disc 15 to rotate through the sleeve 17 and the sliding bolt 18, thereby grinding one end of the raw material cylinder. The debris generated during grinding is confined to the range of the grinding disc 15, thereby reducing the range of debris splashing. At the same time, the negative pressure fan 22 is started, so that no negative pressure airflow is generated in the collection box 2. After passing through the filter part of the interception box 21, the negative pressure airflow is distributed at the diffuser 13 through the transmission and extension of the air guide pipe 6, and the debris generated by the raw material cylinder during grinding is sucked in. The debris will move to the interception box 21 with the negative pressure airflow and be intercepted by the filter of the interception box 21. After the grinding is completed, the power of the negative pressure fan 22 is turned off, and then the interception box 21 is pulled out of the collection box 2 to clean up the intercepted debris.
