[0018] like Figure 1 , Figure 2 and Figure 3 As shown, a preferred embodiment of the present invention provides a billet tail end deburring device, comprising a roll group, a device mounting frame 2, a burr detection mechanism 3 and a deburring mechanism.
[0019] The roll group includes an upper perforated roll 11 and a lower perforated roll 12, which are conical in shape. An entrance guide sleeve 13 is provided on the front side of the upper perforated roll 11 and the lower perforated roll 12. The entrance guide sleeve 13 is arranged horizontally, with one end (right end) of the entrance guide sleeve 13 close to the roll group, and the other end (left end) of the entrance guide sleeve 13 away from the roll group. The entrance guide sleeve 13 is in the shape of a circular tube with openings at both ends for guiding the steel billet 5 to pass through. The upper perforated roller 11 and the lower perforated roller 12 are both connected to the main transmission shaft of the punching machine, and the upper perforated roller 11 and the lower perforated roller 12 are driven to rotate by the main transmission shaft of the punching machine; the billet pushing mechanism 51 pushes the billet 5 from front to back through the entrance guide sleeve 13, so that the head end of the billet 5 contacts the rotating upper perforated roller 11 and the lower perforated roller 12, and the billet 5 is clamped between the upper perforated roller 11 and the lower perforated roller 12, and the upper perforated roller 11 and the lower perforated roller 12 drive the billet 5 to rotate and move forward for rolling.
[0020] like Figure 4As shown, a plug 14 is provided between the upper perforated roller 11 and the lower perforated roller 12, and a pair of guide plates 15 are provided on both sides of the plug 14. The plug 14 is placed between the pair of guide plates 15. The upper perforated roller 11, the lower perforated roller 12, the plug 14 and the guide plates 15 form a closed hole type. The guide plates 15 are all fixed on the working frame of the perforator between the upper perforated roller 11 and the lower perforated roller 12. The plug 14 is connected to the push rod 141. The billet pushing mechanism 51 pushes the billet 5 from front to back and pushes the billet 5 into the perforation of the perforator. When the billet 5 is bitten by the upper perforated roller 11 and the lower perforated roller 12, the billet 5 is rotated in the circumferential direction under the rotation of the upper perforated roller 11 and the lower perforated roller 12, and the plug 14 penetrates into the billet 5 to implement pipe expansion rolling and roll it into a hollow rough pipe.
[0021] A connecting frame 21 is provided on the side of the device mounting frame 2 facing the roll group. The connecting frame 21 is provided with a through hole for the steel billet 5 to pass through. The opening at the other end of the inlet guide sleeve 13 is connected to the through hole of the connecting frame 21. Specifically, a flange can be provided at the other end of the inlet guide sleeve 13. The inlet guide sleeve 13 is fixed to the connecting frame 21 by the flange and screws, so that the opening at the other end of the inlet guide sleeve 13 is connected to the through hole of the connecting frame 21. Figure 1 As shown, the billet pushing mechanism 51 pushes the billet 5 to move horizontally, so that the billet 5 passes through the through hole of the connecting frame 21 and the inlet guide sleeve 13 in sequence.
[0022] The burr detection mechanism 3 is installed on the device mounting frame 2, and is used to detect burrs on the tail end of the steel billet 5. The burr detection mechanism 3 includes an adjustment component installed on the device mounting frame 2 and a burr detection component assembled with the adjustment component. The adjustment component includes an adjustment screw 31 and a first threaded sleeve 32 and a second threaded sleeve 33 that are threadedly connected to both ends of the adjustment screw 31.
[0023] The adjusting screw 31 passes through the device mounting frame 2 from top to bottom, the first screw sleeve 32 is connected to the upper end of the adjusting screw 31 by threading, and the second screw sleeve 33 is connected to the lower end of the adjusting screw 31 by threading. By rotating the adjusting screw 31, the first screw sleeve 32 and the second screw sleeve 33 can be moved in a direction of approaching or moving away from each other, thereby adjusting the distance between the first screw sleeve 32 and the second screw sleeve 33. The first screw sleeve 32 and the second screw sleeve 33 are symmetrical structures, and the first screw sleeve 32 and the second screw sleeve 33 are both provided with a first assembly arm 34 and a second assembly arm 35 at intervals along the radial direction of the steel billet 5, and a reference detection point 341 is provided on the first assembly arm 34.
[0024] The burr detection assembly detects the burrs on the billet 5 by measuring the distance between the reference detection point 341 and the outer peripheral surface of the billet 5. The burr detection assembly includes a floating measuring rod 36 arranged on the first assembly arm 34, a rolling wheel 37 rotatably connected to the floating measuring rod 36, and a displacement sensor 38 arranged on the second assembly arm 35. The floating measuring rod 36 is assembled on the first assembly arm 34 and can move along the radial guide of the billet 5. A measuring rod reset spring 361 is arranged between the first assembly arm 34 and the second assembly arm 35. The measuring rod reset spring 361 is sleeved on the floating measuring rod 36. The end of the floating measuring rod 36 close to the billet 5 is rotatably connected to the rolling wheel 37. The rolling wheel 37 is in rolling contact with the billet 5, and the axis of the rolling wheel 37 extends in the front-rear direction. The displacement sensor 38 is connected to the floating measuring rod 36 and is used to detect the floating amount of the floating measuring rod 36. The displacement sensor 38 can be a laser displacement sensor.
[0025] like Figure 5 As shown, the deburring mechanism is used to remove burrs at the tail end of the billet 5, and includes a cutter head 41 and a cutter head driving component 42 connected to the cutter head 41. The cutter head driving component 42 can drive the cutter head 41 to move radially along the billet 5 so that the cutter head 41 abuts against the outer peripheral surface of the billet 5; when the burr detection component detects the burrs at the tail end of the billet 5, the cutter head 41 removes the burrs at the tail end of the billet 5 during the process of the upper perforating roller 11 and the lower perforating roller 12 driving the billet 5 to rotate.
[0026] Preferably, if Figure 3 As shown, the cutter head drive 42 is assembled on the device mounting frame 2. The cutter head drive 42 can be an electric push rod or a hydraulic cylinder. The cutter head drive 42 and the displacement sensor 38 can be connected to the PLC controller for communication. When the burr detection component detects the burr at the tail end of the billet 5, the displacement sensor 38 sends the detected floating amount of the floating measuring rod 36 to the PLC controller, and the PLC controller controls the cutter head drive 42 to drive the cutter head 41 to extend and retract, so that the cutter head 41 is against the outer peripheral surface of the billet 5, so that during the rotation of the billet 5, the cutter head 41 removes the burr at the tail end of the billet 5.
[0027] Alternatively, if Figure 6 As shown, a notch 131 and a notch 2 132 are respectively provided on the side and the bottom of the inlet guide sleeve 13. The deburring mechanism can be arranged at the notch 131 near the inlet guide sleeve 13. The notch 131 is used for the cutter head driving member 42 and the cutter head 41 to pass through. The cutter head driving member 42 drives the cutter head 41 to move radially along the billet 5 so that the cutter head 41 can cut off the burrs at the tail end of the billet 5. The notch 2 132 is used to collect the burrs cut off.
[0028] The above-mentioned billet tail end deburring device of the present invention is used in conjunction with a punching machine. When in use, the billet pushing mechanism 51 pushes the sawed billet 5 to move from the back to the front, so that the billet 5 passes between the two rolling wheels 37 located on the inner side of the device mounting frame 2 and sequentially passes through the through hole of the connecting frame 21 and the inlet guide sleeve 13. The billet pushing mechanism 51 passes the billet 5 out from the right end of the inlet guide sleeve 13, so that the head end of the billet 5 contacts the rotating upper punching roller 11 and the lower punching roller 12, and the billet 5 is sandwiched between the upper punching roller 11 and the lower punching roller 12, and the upper punching roller 11 and the lower punching roller 12 drive the billet 5 to rotate and move forward for rolling. When the outer circumferential surface of the tail end of the billet 5 contacts the two rolling wheels 37, the burr detection component detects the burrs on the outer circumferential surface of the tail end of the billet 5. When there are burrs on the outer circumferential surface of the billet 5, the corresponding floating measuring rod 36 will float in the direction away from the billet 5, and the displacement sensor 38 detects the floating amount of the floating measuring rod 36 to detect the burrs; the cutter head driving component 42 drives the cutter head 41 to move radially along the billet 5, so that the cutter head 41 abuts against the outer circumferential surface of the billet 5, and removes the burrs at the tail end of the billet 5 during the rotation of the billet 5.
[0029] The above-mentioned billet tail end deburring device drives the billet 5 to rotate during the rolling process through the upper perforated roller 11 and the lower perforated roller 12, detects the burrs at the tail end of the billet 5 using the burr detection mechanism 3, and removes the burrs at the tail end of the billet 5 after sawing using the cutter head 41 of the deburring mechanism, effectively avoiding the burrs from being brought into the hole mold of the continuous rolling mill for rolling, reducing product defects caused by burrs, and improving product quality and yield rate.
[0030] Any details not mentioned in the above specific embodiments of the present invention belong to the known technologies in the art and can be implemented with reference to the known technologies.
[0031] The above is based on the ideal embodiment of the present invention. Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
