[0037] The clamping piece 11 comprises a fixed plate 111 fixedly installed on the workbench 100, one side of the fixed plate 111 is fixedly connected with a telescopic rod 112, and the telescopic end of the telescopic rod 112 is connected with the first guide roller 10; the first guide roller 10 is rotatably installed in a rectangular mounting frame, and the telescopic end of the telescopic rod 112 is connected with the mounting frame; a second elastic piece 113 is fixedly connected between the fixed plate 111 and the first guide roller 10 and outside the telescopic rod 112, the second elastic piece 113 is preferably a rectangular spring, and the telescopic rod 112 is also rectangular in shape; the rectangular shape prevents the second guide roller 40 from shaking in position during telescopic movement, and the rectangular second elastic piece 113 can ensure that its strength is higher than that of ordinary strength, and the material is high-temperature resistant; and the surface of the first guide roller 10 is provided with a recessed groove for abutting the surface of the drill rod; the recessed groove can enable the drill rod with a diameter within a certain range to be clamped and held in the circumferential direction; 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, and the size is not limited;

[0038] A vibrating part 20 for removing the oxide scale on the surface of the heated part of the drill rod by abutting contact is movably arranged at the end of the guide roller on the workbench 100; the vibrating part 20 comprises vibrating balls 21 and moving rods 22; one side of the vibrating ball 21 is provided with an annular moving piece 23 for driving the vibrating ball 21 to perform circumferential movement; the vibrating balls 21 are provided in multiple groups and are uniformly distributed in the circumferential direction of the annular moving piece 23; the multiple groups of vibrating balls 21 form a striking center, and the striking center does not coincide with the center of the annular moving piece 23;

[0039] The annular moving piece 23 comprises an annular frame 231 installed on the workbench 100 through a mounting seat; a moving ring 232 is rotatably installed on one side of the annular frame 231; a driven gear 233 is installed on the outer wall of the moving ring 232; a driven ring 234 is fixedly connected to one side of the moving ring 232; a plurality of limiting frames 235 are fixedly installed on the outer wall of the driven ring 234; the moving rods 22 are slidably installed on the limiting frames 235; the number of the limiting frames 235 matches the number of the moving rods 22; a first elastic piece 236 is arranged between the limiting frames 235 and the moving rods 22 to provide telescopic conditions for the moving rods 22; the first elastic piece 236 is preferably a spring; a driving gear 237 is rotatably installed on the mounting seat and is in meshing connection with the driven gear 233; the driving gear 237 is driven by a first power device, which is preferably a motor;

[0040] When the drill rod needs to be forged, the drill rod can be lifted by a forklift or a lifting device (a crane) and placed into the guide gap 101 between the two groups of first guide rollers 10. When placed, the first elastic member 236 is pressed and stressed, and the recessed groove on the surface of the first guide roller 10 also clamps the circumference of the drill rod. The first guide roller 10 rotates to move the drill rod in the direction of rotation. Until the heated section of the drill rod enters the annular frame 231, at this time, the first power device is started to drive the driving gear 237 to rotate, which drives the driven gear 233 to drive the moving ring 232 to move in a circle. After the moving ring 232 rotates, the limiting frame 235 fixedly connected to the moving ring 232 rotates together, and finally the moving rod 22 and the vibration ball 21 vibrate up and down along the circumferential direction of the drill rod under the action of the second elastic member 113. The center of the drill rod is on the same straight line as the center of the annular frame 231, and the centers of the multiple vibration balls 21 do not coincide with the center of the annular frame 231. That is, the vibration ball 21 acts on the surface of the drill rod at a composite vibration frequency during the movement of the drill rod, so that the drill rod is subjected to eccentric vibration. The wideband vibration of eccentric vibration rather than fixed frequency is more likely to resonate with the oxide skin, causing the oxide skin to shake violently and accelerate the separation from the surface. The irregular impact of eccentric vibration can break the "adsorption strengthening", so that the oxide skin on the surface of the drill rod can be removed by the vibration ball 21 at the beginning of the forging of the drill rod.

[0041] Example two

[0042] With reference to Figures 1-4 , the workbench 100 is provided with a guide conveying unit 30 for guiding and processing the moving drill rod on the side close to the vibration ball 21.

[0047] With reference to Figure 5 and Figures 10-11 , the centering assembly 5 comprises a centering plate 51 coaxially connected with the driven disc 324, and a centering groove 52 is formed in the center position of the centering plate 51, and the second guide roller 40 is rotatably arranged on the top of the centering plate 51; one side of the second guide roller 40 is provided with a motor (not marked in the figure), and the motor and the driving member of the first guide roller 10 are driven by the same controller, so that the second guide roller 40 can continuously transport the drill rod after the first guide roller 10 transports the drill rod, until the drill rod is transported to the forging position; a driving plate 53 is rotatably connected in the centering groove 52, and the driving plate 53 is driven by a switching member 54, and a limiting groove 55 is formed in the driving plate 53, a clamping rod 56 is slidably connected in the centering plate 51, and a limiting column 57 is fixedly connected to the bottom of the clamping rod 56, and the limiting column 57 is connected with the limiting groove 55, and the clamping rod 56 is gathered / dispersed to clamp / separate the drill rod by rotating the driving plate 53 through the switching member 54;

[0048] The mounting plate 31 is provided with a receiving table 200 between the forging table, and the bottom of the receiving table 200 is provided with a collecting opening 201, and one side of the receiving table 200 is provided with an opening 202, and the surface of the receiving table 200 in contact with the drill rod is arc-shaped, which can fit the drill rod and remove the oxide skin on the surface of the drill rod when moving towards the forging table;

[0049] Referring to FIG. 1, Figure 2 and 12 - Figure 13 The re-removing unit 6 includes a frame 61 symmetrically arranged on both sides of the workbench 100, and the frame 61 is provided with a moving groove 62; and a forging table for placing the drill rod is arranged between the oppositely arranged frames 61; the forging table is a prior art for placing the drill rod to be forged, and a forging host is placed on the ground on the side of the forging table opposite to the workbench 100, which is used for forging the front end of the drill rod, and will not be described in detail here. The connecting frame 63 is slidably connected with the moving block 64 in the moving groove 62, the side wall of the connecting frame 63 is tangent to the circumferential direction of the drill rod, and a plurality of cleaning brushes 65 are arranged on the connecting frame 63 in a direction tangent to the drill rod. The moving block 64 drives the cleaning brushes 65 to approach / away from the drill rod through the third power device, the moving block 64 and the third power device are provided with a pushing block 66, and the moving block 64 is slidably connected to the pushing block 66. The third elastic member 67 is arranged between the side wall of the pushing block 66 and the moving block 64, and the elasticity of the third elastic member 67 is greater than the friction between the pushing block 66 and the moving block 64. The third power device is preferably a hydraulic cylinder, and the extension stroke of the hydraulic cylinder is set according to the distance from the forging table, so that the cleaning brushes 65 are not affected by the forging vibration of the forging host on the drill rod when they are not in contact with the forging position of the drill rod, avoiding the adhesion of the oxide skin on the cleaning brushes 65. The material of the cleaning brushes 65 is high-temperature-resistant aluminum oxide, silicon carbide or alloy steel, which can be replaced according to the actual use after long-term use and wear, avoiding affecting the cleaning effect;

[0050] It should be noted that the switching member 54 in the present application is a gear transmission, and a motor is installed on the centering plate 51 to drive the gear, but the switching member 54 is not limited, for example, the telescopic rod 112 can also be used to drive the driving plate 53 to rotate;

[0051] When the drill rod is guided and conveyed by the first guide roller 10, the position that needs to be forged gradually contacts the second guide roller 40, and the drill rod continues to move forward under the re-conveying of the second guide roller 40, sequentially passes through the receiving table 200 and finally makes the forged front end fall on the forging table. When passing through the receiving table 200, the two sides of the receiving table 200 rub against the drill rod, thereby removing the oxide skin on the forged surface of the drill rod again, and the removed oxide skin is collected through the bottom collecting port 201 first (it should be noted that the oxide skin collected at the bottom of the receiving table 200 will be periodically cleaned and treated, and the oxide skin inside is concentrated through the opening and closing port 202 for treatment);

[0052] At this time, the mounting plate 31 is lifted upward under the lifting action of the hydraulic cylinder, and the second guide roller contacts the last end of the drill rod at the same time of lifting, first tilting the one end of the drill rod upward, and finally making the drill rod separate from the second guide roller under the rotation of the second guide roller. It should be noted that the last end of the drill rod does not contact the end of the receiving table 200 at this time, so that the end of the drill rod has a clamping space. The hydraulic cylinder continues to lift the mounting plate 31, and the centering plate 51 and the rotating disc 321 all pass through the workbench 100 and make the centering plate 51 face the axis of the drill rod (the stroke of the hydraulic rod is fixed, so that the axis of the centering plate 51 and the receiving table 200 are on the same horizontal line). Subsequently, the switching piece 54 is started, the switching piece 54 drives the driving plate 53 to rotate in the forward direction, so that the limiting column 57 located in the limiting groove 55 moves, and finally a plurality of clamping rods 56 gather towards the axis of the drill rod, realizing clamping of the drill rod. Conversely, the switching piece 54 drives the driving plate 53 to reverse, and the clamping rod 56 is driven to disperse in the circumferential direction of the drill rod, thereby realizing separation of the drill rod;

[0053] At this time, the third power device is used to push the connecting frame 63 to move along the moving groove 62, so that a plurality of cleaning brushes 65 on the connecting frame 63 roll the oxide skin on both sides of the drill rod again (the rolling period is short, and only the outer wall is cleaned). Since the cleaning brush 65 can rotate, the oxide skin can be rubbed, thereby improving the cleaning efficiency. The cleaning brush 65 at this time is subjected to the extrusion force of the drill rod, so that the third elastic piece 67 is in a compressed state. The cleaning brush 65 of the present application is preferably 2 groups, but is not limited to this, and can be reasonably added according to the diameter of the drill rod;

[0054] When the re-cleaning of the drill rod is completed, the third power device is retracted until it does not affect the forging host and cannot contact it, and does not affect the area change after the drill rod is forged, and the drill rod needs to be rotated by the rotating disc 321 to rotate the driving column 322 into the wheel groove 325 (rotated by 90 degrees), and the abutting plate 323 is matched with the rotating disc 321 to rotate into the arc-shaped avoiding groove 326, so as to realize the stable positioning of the driven disc 324, so that the driven disc 324 rotates, which drives the centering plate 51 to rotate, so that the clamping rod 56 and the drill rod are also correspondingly rotated. When the rotating disc 321 rotates, the third power device drives the cleaning brush 65 to move towards the drill rod, so as to cooperate with the forging of the drill rod to clean the surface 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 adapt to the shape of the cleaning brush 65, so that the cleaning effect is better.

[0055] It should be noted that the pushing block 66 is rhombus-shaped and the third elastic element 67 is also vertically arranged, so that the third elastic element 67 can be compressed to clean the circumferential tangent of the drill rod, thereby expanding the cleaning area.

[0056] The working principle of the present application is as follows:

[0057] Guiding and conveying, the drill rod is lifted by a forklift or a lifting device (a trolley) and is placed into the guiding gap 101 between the two groups of first guide rollers 10 and is pressed by the first elastic element 236, so as to remove part of the oxide scale;

[0058] Primary removal, the heated section of the drill rod is placed into the annular frame 231, at this time, the first power device is started to drive the driving gear 237 to rotate and finally drives the vibration ball 21, so that the vibration ball 21 performs a composite vibration movement around the circumference of the drill rod, thereby achieving better removal of the oxide scale;

[0059] Clamping and centering, the drill rod is guided by the second guide roller 40 again, and a space is reserved at the end of the drill rod to be positioned with the clamping rod 56, so that the clamping rod 56 is centered and fixed, thereby reducing the forging deformation, and the forging section is roughly cleaned by the cleaning brush 65;

[0060] Turnover forging, the rotating disc 321 drives the driven disc 324 to rotate by 90 degrees each time, so that the drill rod can be uniformly forged in the circumferential direction, and the cleaning brush 65 is used for cleaning again after each rotation, and finally the forging is completed.

[0061] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
