Description

Technical Field

[0001] This application relates to the field of drill rod processing technology, and in particular to a guiding device for drill rod processing. Background Technology

[0002] Drill rods are tools used in tunneling engineering to connect drill bits and rock drills. The main processing step for drill rods is forging. Drill rod forging is a key process that achieves densification of the drill rod structure and improves its performance through heating, plastic deformation, and cooling. The core objective is to optimize the hardness, strength, and wear resistance of the working ends (impact end and connection end) of the drill rod while ensuring dimensional accuracy.

[0003] According to patent number CN214236130U, a guiding device for forging drill rods includes a worktable (100). A first hydraulic rod is fixedly installed inside the worktable (100). A sliding block is fixedly connected to the right end of the first hydraulic rod. A barrel is fixedly connected to the top of the sliding block. A fixed disk is fixedly connected inside the barrel. A spiral disk is rotatably connected inside the fixed disk. A spiral groove is formed inside the spiral groove. Four clamping blocks are slidably connected inside the spiral groove. All four clamping blocks are slidably connected to the inside of the fixed disk. A servo motor is rotatably connected to the left side of the barrel. The output shaft of the servo motor is fixedly connected to a first rotating rod via a coupling. The right end of the first rotating rod passes through the barrel and is fixedly connected to the inside of the spiral disk. This invention can effectively and automatically guide drill rods for forging, while reducing the workload of workers and improving processing efficiency.

[0004] However, during the implementation of the relevant technical solutions, at least the following technical problems were found: Oxide scale is generated at the heated part of the drill rod, which is produced by the high temperature of the oxide on the outside of the drill rod. During the forging process, the drill rod deforms and the oxide scale falls off. The drill rod upsetting and thickening device does not treat the fallen oxide scale. If the fallen oxide scale is not treated, it will cause the oxide scale to adhere to its surface during the forging process, affecting the finished product of the drill rod. Summary of the Invention

[0005] This application provides a guiding device for drill rod processing, which solves the problem in the prior art where residual oxide scale left by high temperature on the surface of the drill rod easily adheres to the surface during forging, affecting the quality of the finished product.

[0009] Furthermore, the intermittent flipping assembly includes: a rotating disk, rotatably mounted on a mounting plate via a second power device, with a drive column fixedly connected to the rotating disk and a bonding plate coaxially connected to the rotating disk; a driven disk, rotatably mounted on the mounting plate, with the driven disk and the rotating disk's axis on the same horizontal line, and the driven disk having a wheel groove, the drive column matching the wheel groove, and an arc-shaped clearance groove between two adjacent sets of wheel grooves on the driven disk, the arc-shaped clearance groove cooperating with the bonding plate to limit the position of the driven disk; the drive column enters the wheel groove to cause the wheel groove to rotate cyclically.

[0010] Furthermore, the centering assembly includes: a centering plate, coaxially connected to the driven disk, with a centering groove at the center of the centering plate, and a second guide roller rotatably disposed on the top of the centering plate; a drive plate, rotatably disposed within the centering groove and driven to rotate by a switching component, with a limiting groove provided on the drive plate; a clamping rod, slidably disposed within the centering plate, with its bottom connected to the limiting groove via a limiting post; the switching component causes the drive plate to rotate, causing the clamping rod to converge / disperse to clamp / separate the drill rod.

[0011] Furthermore, the re-removal unit includes: a frame symmetrically arranged on both sides of the workbench, the frame having a moving groove; and a forging press for placing the drill rod between the opposing frames; a connecting frame slidably connected in the moving groove via a moving block, the side wall of the connecting frame being tangent to the circumference of the drill rod, and multiple sets of cleaning brushes arranged on the connecting frame in the direction tangent to the drill rod, the moving block driving the cleaning brushes closer to / away from the drill rod via a third power device.

[0016] The technical solution provided in this application has at least the following technical effects or advantages:

[0017] (1) In this application, the first guide roller and the vibrating part are used so that when the drill rod is transmitted along the first guide roller, the eccentric effect between the vibrating ball and the drill rod causes the force of the vibrating ball on the surface of the drill rod to vibrate irregularly. This not only impacts the surface of the drill rod from multiple directions but also penetrates into dead corners and loosens it. Therefore, it effectively solves the problem that oxide scale easily adheres to the surface of the existing drill rod after high temperature treatment.

[0018] (2) This application uses a second guide roller, a second removal unit, an intermittent flipping assembly and a centering assembly. By utilizing the mutual cooperation between the drive column and the wheel groove, the clamping rod switches positions after it has no rotation. This not only effectively cooperates with the forging device for forging, but also cooperates with the cleaning brush to remove oxide scale from the surface of the forged drill rod. Therefore, it effectively solves the problem of oxide scale adhering to the surface of the drill rod during the forging process, thereby improving the processing quality of the drill rod.

[0033] This application discloses a guiding device for drill rod processing. The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] To better understand the above technical solution, the following will provide a detailed explanation of the above technical solution in conjunction with the accompanying drawings and specific implementation methods.

[0035] Example 1

[0036] Reference Figures 1-4 A guiding device for chisel processing includes a worktable 100 and a first guide roller 10 rotatably mounted on the worktable 100. The number of first guide rollers 10 is arranged in multiple sets, and a guiding gap 101 is formed between two sets of first guide rollers 10 arranged opposite to each other for guiding and feeding chisels of different diameters. A clamping member 11 is provided on one side of the guide roller.

[0037] The clamping member 11 includes a fixing plate 111 fixedly mounted on the workbench 100, and a telescopic rod 112 fixedly connected to one side of the fixing plate 111. The telescopic end of the telescopic rod 112 is connected to a first guide roller 10, which is rotatably mounted within a rectangular mounting frame. The telescopic end of the telescopic rod 112 is connected to the mounting frame. A second elastic element 113 is fixedly connected between the fixing plate 111 and the first guide roller 10, and outside the telescopic rod 112. The second elastic element 113 is preferably a rectangular spring. The shape of 12 is also rectangular. The rectangle prevents the second guide roller 40 from wobbling during telescopic movement. The second elastic element 113 is rectangular, which ensures that its strength is higher than that of ordinary elements. It is also made of high-temperature resistant material. The surface of the first guide roller 10 is provided with a recessed groove for fitting the surface of the drill rod. The recessed groove can allow drill rods with a diameter within a certain range to be inserted and circumferentially clamped. It should be noted that the recessed groove of the first guide roller 10 can be set according to the diameter of the drill rod to be forged as needed, and its size is not limited.

[0038] A vibrating part 20 is movably installed on the worktable 100 at the end of the guide roller to perform preliminary removal of oxide scale on the surface of the drill rod by pressing the heating part against it. The vibrating part 20 includes a vibrating ball 21 and a moving rod 22. A ring moving member 23 is provided on one side of the vibrating ball 21 to drive it to perform circumferential motion. There are multiple sets of vibrating balls 21, which are evenly distributed in the circumferential direction of the ring moving member 23. The multiple sets of vibrating balls 21 form a striking center, and the striking center does not coincide with the center of the ring moving member 23.

[0039] The annular moving component 23 includes an annular frame 231 mounted on the workbench 100 via a mounting base. A moving ring 232 is rotatably mounted on one side of the annular frame 231, and a driven gear 233 is mounted on the outer wall of the moving ring 232. A driven ring 234 is fixedly connected to one side of the moving ring 232, and multiple sets of limiting frames 235 are fixedly mounted on the outer wall of the driven ring 234. The moving rod 22 is slidably mounted on the limiting frame 235, and the number of limiting frames 235 matches the number of moving rods 22. A first elastic element 236 is provided between the limiting frame 235 and the moving rod 22 to provide extension and retraction conditions for the moving rod 22. The first elastic element 236 is preferably a spring. A driving gear 237 is rotatably mounted on the mounting base and meshes with the driven gear 233. The driving gear 237 is driven by a first power device, which is preferably a motor.

[0040] When forging is required, a forklift or lifting device (overhead crane) can be used to lift the drill rod and place it into the guide gap 101 between the two sets of first guide rollers 10. Simultaneously, the first elastic element 236 is compressed, and the grooves on the surface of the first guide rollers 10 clamp the circumference of the drill rod. The rotation of the first guide rollers 10 causes the drill rod to move in its rotational direction until the heated section of the drill rod enters the annular frame 231. After entering the annular frame 231, the first power device is activated, driving the drive gear 237 to rotate. The drive gear 237 transmits power to the driven gear 233, thereby driving the moving ring 232 to perform circumferential motion. After the moving ring 232 rotates, the limiting frame 23 fixedly connected to the moving ring 232... 5. Following its rotation, the moving rod 22 and the vibrating ball 21 eventually extend and vibrate up and down along the circumference of the drill rod under the action of the second elastic element 113. The center of the drill rod and the center of the ring frame 231 are on the same straight line, while the centers of the multiple sets of vibrating balls 21 do not coincide with the center of the ring frame 231. That is, during the movement of the drill rod, the vibrating balls 21 act on the surface of the drill rod with a composite vibration frequency, thereby enabling the drill rod to be subjected to eccentric vibration. The wide-band vibration of the eccentric vibration, rather than a fixed frequency, is more likely to resonate with the oxide scale, causing the oxide scale to shake violently and accelerate its removal from the surface. The irregular impact of the eccentric vibration can break this "adsorption strengthening", thus enabling the oxide scale on the surface of the drill rod to be removed by the vibrating ball 21 at the initial stage of forging the drill rod.

[0041] Example 2

[0042] Reference Figures 1-4 A guide conveying unit 30 for guiding the moving chisel is provided on the side of the workbench 100 near the vibrating ball 21. The guide conveying unit 30 includes a mounting plate 31 that can be lifted and lowered on the workbench 100. The workbench 100 has a moving groove 62 at the position of the mounting plate 31, which can facilitate the lifting and lowering of the mounting plate 31. A hydraulic cylinder is installed at the bottom of the workbench 100. The telescopic end of the hydraulic cylinder is fixedly connected to the mounting plate 31, which can operate the mounting plate 31 to pass through the moving groove 62 from the bottom of the workbench 100 and be lifted onto the workbench 100.

[0043] Reference Figure 2 , Figure 6 , Figure 8 The mounting plate 31 is provided with an intermittent flipping assembly 32 for switching after the drill rod rotates 90 degrees in each direction. A second guide roller 40 is provided on one side of the mounting plate 31, and a centering assembly 5 for the drill rod is provided at the bottom of the second guide roller 40, and a re-removal unit 6 for removing the circumferential oxide scale of the drill rod during the forging process.

[0044] The intermittent flipping assembly 32 includes a rotating disk 321 rotatably mounted on a mounting plate 31 via a second power device, and a drive column 322 is fixedly connected to the rotating disk 321, and a bonding plate 323 is coaxially connected to the rotating disk 321.

[0045] The end of the workbench 100 is provided with a re-removal unit 6 for removing the circumferential oxide scale from the drill rod during the forging process;

[0046] Reference Figures 1-2 and Figure 8 The intermittent flipping assembly 32 includes a rotating disk 321 rotatably mounted on a mounting plate 31 via a second power device. A drive column 322 is fixedly connected to the rotating disk 321, and a bonding plate 323 is coaxially connected to the rotating disk 321. A driven disk 324 is rotatably mounted on the mounting plate 31, and the axis of the driven disk 324 and the rotating disk 321 are on the same horizontal line. A wheel groove 325 is formed on the driven disk 324, and the drive column 322 matches the wheel groove 325. The open end of each wheel groove 325 is provided with a guide surface 327 to facilitate the entry of the drive column 322. An arc-shaped clearance groove 326 is formed between two adjacent sets of wheel grooves 325 on the driven disk 324. The arc-shaped clearance groove 326 cooperates with the bonding plate 323 to limit the position of the driven disk 324. The drive column 322 enters into the wheel groove 325 to make the wheel groove 325 rotate 90 degrees.

[0047] Reference Figure 5 and Figures 10-11 The centering assembly 5 includes a centering plate 51 coaxially connected to the driven disk 324, and a centering groove 52 is provided at the center position of the centering plate 51. The second guide roller 40 is rotatably disposed on the top of the centering plate 51. A motor (not shown in the figure) is provided on one side of the second guide roller 40. This motor and the drive component of the first guide roller 10 are driven by the same controller, so that the second guide roller 40 can continue to continuously convey the drill rod after the first guide roller 10 has conveyed it. The drill rod is conveyed to the forging position. A drive plate 53 is rotatably connected in the centering groove 52, and the drive plate 53 is driven by the switching component 54. A limit groove 55 is opened on the drive plate 53. A clamping rod 56 is slidably connected in the centering plate 51. A limit post 57 is fixedly connected to the bottom of the clamping rod 56. The limit post 57 is connected to the limit groove 55. The drive plate 53 is rotated by the switching component 54 to make the clamping rod 56 gather / disperse to clamp / separate the drill rod.

[0048] A receiving platform 200 is installed between the mounting plate 31 and the forging table. The bottom of the receiving platform 200 is provided with a collection port 201, and one side of the receiving platform 200 is provided with an opening and closing port 202. The surface of the receiving platform 200 that contacts the drill rod is arc-shaped, which can fit the drill rod while allowing the oxide scale on the surface of the drill rod to be rubbed off when the drill rod moves toward the forging table.

[0049] Reference,1- Figure 2 and 12 - Figure 13 The re-removal unit 6 includes frames 61 symmetrically arranged on both sides of the workbench 100, each frame 61 having a movable groove 62. A forging platform for placing the drill rod is provided between the opposing frames 61. The forging platform is existing technology and is used to place the drill rod to be forged. A forging host is placed on the ground on the side of the forging platform opposite to the workbench 100 to forge the front end of the drill rod. Details are omitted here. A connecting frame 63 is slidably connected to the movable groove 62 via a movable block 64. The side wall of the connecting frame 63 is tangent to the circumference of the drill rod. Multiple sets of cleaning brushes 65 are arranged on the connecting frame 63 in the direction tangent to the drill rod. The movable block 64 drives the cleaning brushes 65 closer to / away from the drill rod via a third power device. The movable block 64 and... A push block 66 is provided between the third power devices, and the moving block 64 is slidably connected to the push block 66. A third elastic element 67 is provided between the side wall of the push block 66 and the moving block 64, and the elasticity of the third elastic element 67 is greater than the friction between the push block 66 and the moving block 64. The third power device is preferably a hydraulic cylinder, and the extension and retraction stroke of the hydraulic cylinder is set according to the distance from the forging table, so that the cleaning brush 65 is not affected by the vibration of the forging host on the forging of the drill rod when it is not in contact with the forging position of the drill rod, thus avoiding the oxide scale from adhering to the cleaning brush 65. The cleaning brush 65 is made of high temperature resistant alumina, silicon carbide or alloy steel, and can be replaced according to the actual use after long-term wear, thus avoiding affecting the cleaning effect.

[0050] It should be noted that the switching component 54 in this application is a gear drive, and a motor is installed on the centering plate 51 to drive the gear. However, the switching component 54 is not limited. For example, it can also be a telescopic rod 112 that extends and retracts to make the drive plate 53 rotate.

[0051] As the drill rod is guided and conveyed by the first guide roller 10, the position to be forged gradually comes into contact with the second guide roller 40. Under the further conveying of the second guide roller 40, the drill rod continues to move forward, passing through the receiving platform 200 in sequence and finally having its forging front end land on the forging platform. When passing through the receiving platform 200, the two sides of the receiving platform 200 rub against the drill rod, thereby removing the oxide scale from the forging surface of the drill rod again. The removed oxide scale is first collected through the bottom collection port 201 (it should be noted that when the oxide scale collected at the bottom of the receiving platform 200 is to be cleaned periodically, the oxide scale inside is collected and processed through the opening and closing port 202).

[0052] At this time, the mounting plate 31 rises upward under the lifting action of the hydraulic cylinder. Simultaneously, the second guide roller contacts the very end of the chisel, first tilting one end of the chisel upward. Then, under the rotation of the second guide roller, the chisel finally disengages from the second guide roller. It should be noted that at this point, the very end of the chisel does not contact the end of the receiving platform 200, thus providing a clamping space for the end of the chisel. The hydraulic cylinder continues to lift the mounting plate 31, causing both the centering plate 51 and the rotating disk 321 to pass through the worktable 100, with the centering plate 51 facing directly towards... With the axis of the drill rod in the center (the stroke of the hydraulic rod is fixed so that the centering plate 51 and the axis of the receiving platform 200 are on the same horizontal line), the switching component 54 is activated. The switching component 54 drives the drive plate 53 to rotate clockwise, thereby moving the limiting post 57 located in the limiting groove 55. Finally, multiple sets of clamping rods 56 are brought together toward the axis of the drill rod to clamp the drill rod. Conversely, the switching component 54 drives the drive plate 53 to rotate counterclockwise, which drives the clamping rods 56 to disperse in the circumferential direction of the drill rod, thereby separating the drill rod.

[0053] At this point, the connecting frame 63 is first moved along the moving groove 62 by the third power device, so that the multiple sets of cleaning brushes 65 on the connecting frame 63 can be used to brush the oxide scale on both sides of the drill rod again (the brushing cycle is short, and it only roughly cleans the outer wall). Since the cleaning brushes 65 can rotate, they can achieve friction against the oxide scale, thereby making the cleaning efficiency higher. At this time, the cleaning brushes 65 will be subjected to the squeezing force of the drill rod, so that the third elastic element 67 is in a compressed state. The cleaning brushes 65 in this application are preferably two sets, but not limited to, and can be reasonably added according to the diameter of the drill rod.

[0054] After the drill rod is cleaned again, the third power device retracts until it is so that it does not affect the forging host and does not affect the change in the area of ​​the drill rod after forging. During forging, the drill rod needs to be rotated by the rotating disk 321 to make the drive column 322 rotate into the wheel groove 325 (rotate 90 degrees). The fitting plate 323 cooperates with the rotating disk 321 to rotate into the arc-shaped clearance groove 326, so as to achieve stable limiting of the driven disk 324, thereby making the driven disk 324 rotate. The rotation of the driven disk 324 will drive the centering plate 51 to rotate, which can drive the clamping rod 56 and the drill rod to rotate accordingly. When the rotating disk 321 rotates, the third power device drives the cleaning brush 65 to move towards the drill rod, thereby cleaning its surface in conjunction with the forging of the drill rod. At the same time, since the front end of the drill rod has been deformed, the third elastic element 67 can make the cleaning brush 65 adapt to its shape, thereby improving the cleaning effect.

[0055] It should be noted that the push block 66 is rhomboid and the third elastic element 67 is also set perpendicular to the rhomboid, which enables the third elastic element 67 to be compressed and cleaned along the circumferential tangent of the drill rod, thereby expanding its cleaning area.

[0056] How this application works:

[0057] The guide conveyor uses a forklift or lifting device (overhead crane) to lift the drill rod and place it into the guide gap 101 between two sets of first guide rollers 10, where it is squeezed by the first elastic element 236 to remove part of the oxide scale.

[0058] During the initial removal, the heated section of the drill rod enters the annular frame 231. At this time, the first power device is activated, driving the drive gear 237 to rotate and ultimately transmitting the transmission to the vibrating ball 21, causing the vibrating ball 21 to perform a compound vibration motion around the circumference of the drill rod, thereby achieving better removal of oxide scale.

[0059] The clamping and centering process guides the chisel through the second guide roller 40 again, leaving space at its end for positioning with the clamping rod 56. The clamping rod 56 then centers and fixes the chisel to reduce forging deformation. Meanwhile, the forging section is roughly cleaned by the cleaning brush 65.

[0060] The forging process involves rotating the rotating disk 321 to drive the driven disk 324 to rotate 90 degrees each time, thereby enabling uniform circumferential forging of the drill rod. After each rotation, the drill rod is cleaned again by the cleaning brush 65, and finally the forging is completed.

[0061] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.

[0062] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present application, based on the technical solution and concept of the present application, should be covered within the scope of protection of the present application.
