Description

Technical Field

[0001] The invention relates to the technical field of metal piece cutting, in particular to a metal piece cutting device with an edge trimming function. Background Art

[0002] Metal cutting equipment plays a vital role in industrial production and carries far-reaching significance. These devices can efficiently and accurately cut a variety of metal materials, meeting the manufacturing industry's demand for high-precision and high-efficiency processing. With the continuous advancement of technology, the application prospects of these devices will be broader, providing strong support for the future development of the manufacturing industry.

[0003] Although cutting equipment has been vigorously developed, burrs are prone to occur during cutting, and with long-term use, the cutting head will suffer from wear and chipping. The metal cutting equipment currently on the market is difficult to ensure the flatness and roughness of the cutting edge, and with the transmission of the transmission mechanism, the metal parts will be displaced and swing, which makes it easy to produce bevel edges during cutting. Summary of the invention

[0004] The object of the present invention is to provide a metal piece cutting device with edge trimming function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a metal cutting device with edge trimming function, comprising a main base, on which a first electric transmission wheel and a second electric transmission wheel are rotatably installed respectively, a lower cutting table is installed on the main base, a deviation correction and positioning component is slidably installed on the lower cutting table, an edge repair component is installed on the lower cutting table, a hydraulic drive component is installed on the main base, a cutting head is installed on the hydraulic drive component, a fixing component is installed on the main base, a sliding hole is provided on the lower cutting table, a third electric telescopic rod is installed in the lower cutting table, and a push rod is installed on the third electric telescopic rod; the deviation correction and positioning component comprises a threaded transmission rod and a transmission gear, the transmission gear is rotatably installed on the lower cutting table, the threaded transmission rod is slidably installed on the lower cutting table through the sliding hole, the threaded transmission rod is provided with threads, and the threaded transmission rod is threadedly connected to the transmission gear.

[0006] A control system is installed in the main base, and the control system is used to control the entire metal cutting equipment.

[0007] The deviation correction and positioning assembly also includes a deviation correction rack, which is slidably installed on the lower cutting table, the deviation correction rack is meshed with the transmission gear for transmission, a positioning telescopic rod is slidably installed in the deviation correction rack, a detection positioning head is installed at one end of the positioning telescopic rod, a transmission pressure rod is installed on the threaded transmission rod, a downward pressure spring is installed at the bottom end of the transmission pressure rod, a positioning plate is installed at the bottom end of the downward pressure spring, and a reset spring is installed between the transmission pressure rod and the lower cutting table.

[0008] After the transmission pressure rod is subjected to the pressure of the lower pressure beam, it overcomes the elastic force of the reset spring and moves downward, and the transmission pressure rod drives the threaded transmission rod to descend, and the threaded transmission rod drives the transmission gear to move. Since the transmission gear is rotatably installed on the lower cutting table and cannot move, under the action of the thread, the transmission gear converts the vertical movement into rotation, and the transmission gear drives the correction rack to slide through rotation, and the correction rack drives the detection positioning head to approach the side of the metal part through the positioning telescopic rod.

[0009] The detection and positioning head includes a correction frame, a correction wheel is rotatably installed in the correction frame, a measuring wheel assembly is slidably installed in the correction frame, and the measuring wheel assembly is located on both sides of the correction wheel; the measuring wheel assembly includes a detection shell and a correction measuring rod, one end of the correction measuring rod passes through the correction frame and is installed with a piston head, the detection shell is installed on the correction frame, the piston head is slidably installed in the detection shell, a transmission slide is slidably installed in the detection shell, a first piezoelectric element is installed in the detection shell, the transmission slide is fitted with the first piezoelectric element, the other end of the correction measuring rod is rotatably installed with a detection wheel, and a detection spring is installed between the correction measuring rod and the correction frame. The elastic coefficient of the detection spring is smaller than the elastic coefficient of the positioning spring.

[0010] As the detection positioning head gradually approaches the side of the metal part, the measuring wheel assembly on the detection positioning head first contacts the metal part, and the detection wheel on the measuring wheel assembly is squeezed by the metal part, driving the correcting measuring rod to retract, and the correcting measuring rod drives the piston head to slide in the detection shell and compress the medium in the detection shell. After the medium is compressed, the pressure in the detection shell increases, and the transmission slide is compressed to squeeze the first piezoelectric element. The first piezoelectric element generates an electric charge after being compressed, and the charge is transmitted to the control system through the wire. The control system records and analyzes the electrical signal. When the detection spring is fully compressed, the detection The measuring wheel is flush with the correcting wheel. At this time, the detection wheels and the correcting wheels on both sides squeeze the metal part together. Under the equal squeezing force on both sides, the metal part is gradually centered. The control system analyzes the centering of the metal part through the size of the electrical signals of multiple groups of first piezoelectric elements. When the electrical signal is within the error range, it proves that the metal part is in the center state. If the error between the electrical signals is too large, it means that the metal part is not centered or the metal part is asymmetrical. The control system sends an alarm to the staff, and the staff debugs the equipment and measures and checks the size of the metal parts, thereby achieving the correction and size screening of the metal parts.

[0011] When the metal part is centered, as the transmission pressure rod descends, the positioning plate just contacts with the upper surface of the metal part, and the control system drives the output shaft of the hydraulic device to further extend, pushing the lower pressure beam to descend, and the lower pressure beam drives the transmission pressure rod to descend, and the transmission pressure rod drives the positioning plate to continue to descend. Since the positioning plate fits the surface of the metal part and cannot descend, the lower pressure spring is compressed under the pressure at both ends. After the lower pressure spring is compressed, a reaction force is generated on the positioning plate. Under the action of the reaction force, the positioning plate presses and tightens the metal part. At this time, the threaded transmission rod drives the detection positioning head forward through the transmission gear. Since the detection positioning head is in contact with the side of the metal part and cannot move, the positioning spring begins to be compressed. After the positioning spring is compressed, a reaction force is generated on the detection positioning head, so that the detection positioning head presses and tightens the two sides of the metal part, thereby achieving the purpose of positioning and tightening the metal part on all sides. When the lower pressure spring is compressed to a certain amount, the cutting head on the lower pressure beam cuts the plate-shaped metal part, and the cutting head is displaced from one side of the lower cutting table. The shear force generated by the dislocation cuts the metal part, and the cutting is just completed after the lower pressure spring is fully compressed.

[0012] The edge repair component includes a repair bracket and a repair motor. The repair bracket is slidably connected to the lower cutting table. The repair motor is installed on the lower cutting table. The output shaft of the repair motor passes through the lower cutting table and is connected to a screw rod. The screw rod is rotatably connected to the lower cutting table. The screw rod is provided with threads. The screw rod is threadedly connected to the repair bracket. An edge detector is installed on the repair bracket.

[0013] The edge repair component also includes a grinding motor and a second rotating shaft. The grinding motor is installed on the repair bracket. The output shaft of the grinding motor passes through the repair bracket and is connected to the first rotating shaft. The first rotating shaft is installed with a first grinding roller. The bottom end of the first rotating shaft is installed with a first gear. The first rotating shaft is rotatably connected to the repair bracket. The second rotating shaft is rotatably installed on the repair bracket. The second rotating shaft is installed with a second grinding roller. The second rotating shaft is installed with a second gear. The second gear is meshed with the first gear for transmission.

[0014] After the inspection is completed, the control system turns on the first electric telescopic rod and the third electric telescopic rod. The output shaft of the third electric telescopic rod drives the pushing rod to extend. The pushing rod cooperates with the L-shaped baffle to clamp the cut finished metal parts front and back. The output shaft of the first electric telescopic rod drives the electric gripper to extend, and the electric gripper clamps the two sides of the finished metal parts. The control system turns on the electric gripper, and the electric gripper gripper retracts to clamp the finished metal parts, and then resets the third electric telescopic rod. The control system controls the repair motor to reverse, and the repair motor drives the screw rod to rotate in the opposite direction, so that the edge repair component slides in the opposite direction. When the edge repair component moves to the defective part, the control system starts the grinding motor, and the output shaft of the grinding motor drives the first shaft to rotate, the first shaft drives the first gear and the first grinding roller to rotate, the first gear drives the second gear to rotate, the second gear drives the second shaft to rotate, and the second shaft drives the second grinding roller to rotate. The first grinding roller moves while grinding the cut surface of the metal part, and the second grinding roller moves while grinding the cut surface of the finished metal part. After the cut surface of the metal part is polished, the edge detector moving in the opposite direction performs a second detection on the polished edge, and repeats from then on until the edge of the metal part is corrected. The control system controls the electric gripper to reset, and controls the L-shaped baffle to descend through the second electric telescopic rod, and then uses the second electric transmission wheel to transport the finished metal part.

[0015] The edge detector includes a spring telescopic rod, which is embedded in the repair bracket, a detection frame is installed on the spring telescopic rod, a slide rail is provided on the detection frame, and a detection block is slidably installed on the detection frame through the slide rail; a slide groove is provided on the detection block, and the detection block is slidably connected to the slide rail through the slide groove, and a friction plate is provided on the detection block, and a measuring wheel hole and a contact hole are respectively provided on the detection block. The friction plate is made of a high friction coefficient material.

[0016] After the cutting is completed, the control system controls the cutting head to lift and maintain the clamping state of the fixed column, the control system starts the repair motor, the repair motor drives the screw to rotate, the screw drives the repair bracket to slide linearly along the screw direction, the repair bracket drives the edge detector to slide, and the detection block on the edge detector begins to contact the cutting surface on the metal plate as it slides, and the friction plate on the detection block produces friction with the cutting surface. Under the action of friction, the detection block and the detection frame produce relative displacement, and the friction spring on one side of the detection frame is compressed. At this time, the detection block is close to one side of the compressed friction spring, and the iron core column on it passes through the induction coil, and the induction coil generates an induced electromotive force. When burrs appear on the cross section of the metal part, the friction between the friction plate and the cross section of the metal part will increase, thereby increasing the distance that the iron core column passes through the induction coil, generating a larger induced electromotive force. The control system records and analyzes the changes in the induced electromotive force through the wire, and analyzes the roughness of the cross section of the metal part by comparing the induced electromotive force with the standard value. At the same time, the specific location of the burr can be analyzed according to the time node of the change in the induced electromotive force.

[0017] The edge detector also includes a measuring wheel rod, which passes through the measuring wheel hole, a flatness measuring wheel is rotatably installed between the measuring wheel rods, a detection contact is installed at one end of the measuring wheel rod, a measuring wheel spring is installed between the measuring wheel rod and the detection block, an induction head is slidably installed in the contact hole, a diaphragm is installed in the contact hole, a second piezoelectric element is installed between the diaphragms, an iron core column is installed on the detection block, the iron core column is slidably connected to the detection frame, an induction coil is wound on the detection frame, and a friction spring is installed between the detection block and the detection frame.

[0018] When the edge detector slides, the flatness measuring wheel rolls on the cross-section of the metal part. When a bulge appears on the cross-section, the flatness measuring wheel will bump. When the flatness measuring wheel is displaced, it will drive the detection contact to displace. When the flatness is unqualified, the detection contact will be displaced to a large extent, and when it moves to the position of the sensing head, the detection contact will squeeze the sensing head. After the sensing head is compressed, it squeezes the diaphragm. The diaphragm squeezes the second piezoelectric element inside. The compressed second piezoelectric element generates an electrical signal. The control system records and analyzes the time node when the electrical signal is generated, so as to obtain the position of the bulge. The staff will detect the cutting head in the relative position according to the position point to detect whether the cutting head has defects, so as to detect the flatness of the cutting edge and the wear of the cutting head.

[0019] The hydraulic drive component includes a positioning column, which is installed on the main base. A crossbeam is installed on the top of the positioning column, and a hydraulic device is installed on the crossbeam. The output shaft of the hydraulic device passes through the crossbeam and is installed with a downward pressure beam. The downward pressure beam is slidably connected to the positioning column, and a cutting head is installed on the downward pressure beam; the fixed component includes a first electric telescopic rod and a second electric telescopic rod, both of which are installed on the main base, an electric gripper is installed on the output shaft of the first electric telescopic rod, and an L-shaped baffle is installed on the output shaft of the second electric telescopic rod.

[0020] The control system controls the first electric transmission wheel to transport the plate-shaped metal part. When one end of the metal part contacts the L-shaped baffle, it stops. The control system starts the hydraulic device. The output shaft of the hydraulic device drives the pressure beam to slide down along the positioning column. After the pressure beam slides down a certain distance, it contacts the transmission pressure rod.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The descent of the lower pressure beam is converted into the displacement of the detection and positioning head, and the detection and positioning head is used to correct the metal part. The correction condition is detected by the detection and positioning head. The multiple detection wheels on the detection and positioning head convert the centering condition of the metal part into a detectable electrical signal. The control system analyzes the centering condition of the metal part by analyzing the size of the electrical signal. When the electrical signal is within the error range, it proves that the metal part is in the center state. If the error between the electrical signals is too large, it means that the metal part is not centered or the metal part is asymmetrical, thereby achieving the effect of metal part correction and size screening.

[0023] 2. Use the flatness measuring wheel to detect the protrusions on the cutting surface of the metal part, convert the protrusions into the displacement of the flatness measuring wheel, and then convert the displacement into a recognizable electrical signal. The control system records and analyzes the time node when the electrical signal is generated to obtain the position of the protrusion. The staff will detect the cutting head in relative position according to the position point to detect whether there is any defect in the cutting head, thereby achieving the detection of the flatness of the cutting edge and the wear of the cutting head.

[0024] 3. Use the edge detector to detect the cut surface of the metal part, rub the detection block against the cut surface of the metal part, convert the cross-section roughness detection into the friction force detection, and then convert the friction force into a detectable electrical signal. By analyzing the electrical signal, the roughness of the cross section of the metal part is analyzed, and the specific location of the burr is analyzed according to the time node of the change of the induced electromotive force, thereby realizing the detection and positioning of the burr.

[0025] 4. The electric gripper, L-shaped baffle and positioning plate cooperate with each other to achieve the position adjustment and fixed clamping of the finished metal parts; the first grinding roller and the second grinding roller are used to grind and trim the metal parts to be cut and the cut surfaces of the finished metal parts at the same time, and then the reverse moving edge detector is used to perform a second inspection on the grinding edge to ensure the quality of the trimming.

[0026] 5. The positioning plate and the detection positioning head cooperate with each other to achieve the purpose of positioning and tightening the metal parts on all four sides. The metal parts are cut through the shear force generated by the displacement of the cutting head and one side of the lower cutting table, so that the metal parts can be cut while being tightened on all four sides, ensuring the neatness of the cut edges of the metal parts.

[0047] The edge repair component 6 also includes a grinding motor 611 and a second rotating shaft 610. The grinding motor 611 is installed on the repair bracket 64. The output shaft of the grinding motor 611 passes through the repair bracket 64 and is connected to the first rotating shaft 66. The first rotating shaft 66 is installed with a first grinding roller 65. The bottom end of the first rotating shaft 66 is installed with a first gear 67.

The second grinding roller 69 is installed on the second rotating shaft 610. The second gear 68 is installed on the second rotating shaft 610. The second gear 68 is meshed with the first gear 67 for transmission.

[0048] The working principle of the present invention is as follows: the control system controls the first electric transmission wheel 1 to transport the plate-shaped metal parts. When one end of the metal parts contacts the L-shaped baffle 74, it stops. The control system starts the hydraulic device 51. The output shaft of the hydraulic device 51 drives the pressure beam 52 to slide down along the positioning column 54. After the pressure beam 52 slides down a certain distance, it contacts the transmission pressure rod 41.

[0049] After the transmission pressure rod 41 is subjected to the pressure of the lower pressure beam 52, it overcomes the elastic force of the reset spring 45 and moves downward, and the transmission pressure rod 41 drives the threaded transmission rod 44 to descend, and the threaded transmission rod 44 drives the transmission gear 47 to move. Since the transmission gear 47 is rotatably installed on the lower cutting table 8 and cannot move, under the action of the thread, the transmission gear 47 converts the vertical movement into rotation, and the transmission gear 47 drives the correction rack 46 to slide through the rotation, and the correction rack 46 drives the detection positioning head 43 to approach the side of the metal part through the positioning telescopic rod 48.

[0050] As the detection positioning head 43 gradually approaches the side of the metal part, the measuring wheel assembly 433 on the detection positioning head 43 first contacts the metal part, and the detection wheel 4331 on the measuring wheel assembly 433 is squeezed by the metal part, driving the correcting measuring rod 4332 to retract, and the correcting measuring rod 4332 drives the piston head 4334 to slide in the detection shell 4335 and compresses the medium in the detection shell 4335. After the medium is compressed, the pressure in the detection shell 4335 increases, and the transmission slide 4336 is compressed to squeeze the first piezoelectric element 4337. The first piezoelectric element 4337 generates an electric charge after being compressed, and the charge is transmitted to the control system through the wire, and the control system records and analyzes the electrical signal. When the detection spring 4333 is fully compressed, the detection wheel 4331 is flush with the correcting wheel 432. At this time, the detection wheels 4331 and the correcting wheels 432 on both sides squeeze the metal part together. Under the equal squeezing force on both sides, the metal part is gradually centered. The control system analyzes the centering of the metal part through the size of the electrical signals of multiple groups of first piezoelectric elements 4337. When the electrical signal is within the error range, it proves that the metal part is in the center state. If the error between the electrical signals is too large, it means that the metal part is not centered or the metal part is asymmetrical. The control system sends an alarm to the staff, and the staff debugs the equipment and measures and checks the size of the metal part, thereby achieving the correction and size screening of the metal part.

[0051] When the metal part is centered, as the transmission pressure rod 41 descends, the positioning plate 410 just contacts the upper surface of the metal part, and the control system drives the output shaft of the hydraulic device 51 to further extend, pushing the lower pressure beam 52 to descend, and the lower pressure beam 52 drives the transmission pressure rod 41 to descend, and the transmission pressure rod 41 drives the positioning plate 410 to continue to descend. Since the positioning plate 410 is in contact with the surface of the metal part and cannot descend, the downward pressure spring 42 is compressed under the pressure at both ends. After the downward pressure spring 42 is compressed, a reaction force is generated on the positioning plate 410. Under the action of the reaction force, the positioning plate 410 presses and tightens the metal part. At this time, the threaded transmission rod 44 passes through the transmission gear The wheel 47 drives the detection and positioning head 43 to extend forward. Since the detection and positioning head 43 is in contact with the side of the metal part and cannot move, the positioning spring 49 begins to be compressed. After the positioning spring 49 is compressed, a reaction force is generated on the detection and positioning head 43, so that the detection and positioning head 43 presses and tightens the two sides of the metal part, thereby achieving the purpose of positioning and tightening the metal part on all four sides. When the lower pressure spring 42 is compressed to a certain amount, the cutting head 9 on the lower pressure beam 52 cuts the plate-like metal part, and the cutting head 9 is offset from one side of the lower cutting table 8. The shear force generated by the offset cuts the metal part. After the lower pressure spring 42 is fully compressed, the cutting is just completed.

[0052] After the cutting is completed, the control system controls the cutting head 9 to lift and maintain the clamping state of the fixed column, and the control system starts the repair motor 61, and the repair motor 61 drives the screw rod 62 to rotate, and the screw rod 62 drives the repair bracket 64 to slide linearly along the direction of the screw rod 62, and the repair bracket 64 drives the edge detector 63 to slide, and the detection block 633 on the edge detector 63 begins to contact the cutting surface on the metal plate as it slides, and the friction plate 6331 on the detection block 633 generates friction with the cutting surface. Under the action of friction force, the detection block 633 and the detection bracket 6313 generate relative displacement, and the friction spring 635 on one side of the detection bracket 6313 is compressed. At this time, the detection The measuring block 633 is close to one side of the compressed friction spring 635, and the iron core column 634 on it passes through the induction coil 632. The induction coil 632 generates an induced electromotive force. When burrs appear on the cross section of the metal part, the friction between the friction plate 6331 and the cross section of the metal part will increase, thereby increasing the distance that the iron core column 634 passes through the induction coil 632, generating a larger induced electromotive force. The control system records and analyzes the changes in the induced electromotive force through the wire, and analyzes the roughness of the cross section of the metal part by comparing the induced electromotive force with the standard value. At the same time, the specific location of the burr can be analyzed based on the time node of the change in the induced electromotive force.

[0053] When the edge detector 63 slides, the flatness measuring wheel 636 rolls on the cross section of the metal part. When a bulge appears on the cross section, the flatness measuring wheel 636 will be bumpy. When the flatness measuring wheel 636 is displaced, it will drive the detection contact 639 to displace. When the flatness is unqualified, the detection contact 639 is displaced to a large extent, and when it is displaced to the position of the sensing head 6310, the detection contact 639 squeezes the sensing head 6310. After the sensing head 6310 is compressed, it squeezes the diaphragm 6311. The diaphragm 6311 squeezes the second piezoelectric element 6312 inside. The compressed second piezoelectric element 6312 generates an electrical signal. The control system records and analyzes the time node when the electrical signal is generated, so as to obtain the position of the bulge. The staff detects the cutting head 9 in the relative position according to the position point to detect whether the cutting head 9 is defective, thereby achieving the detection of the flatness of the cutting edge and the wear of the cutting head 9.

[0054] After the detection is completed, the control system turns on the first electric telescopic rod 71 and the third electric telescopic rod 82. The output shaft of the third electric telescopic rod 82 drives the pushing rod 81 to extend. The pushing rod 81 cooperates with the L-shaped baffle 74 to clamp the cut finished metal parts front and back. The output shaft of the first electric telescopic rod 71 drives the electric gripper 72 to extend. The electric gripper 72 clamps the two sides of the finished metal parts. The control system turns on the electric gripper 72. The gripper of the electric gripper 72 retracts to clamp the finished metal parts, and then resets the third electric telescopic rod. The control system controls the repair motor 61 to reverse, and the repair motor 61 drives the screw 62 to rotate in the opposite direction, so that the edge repair component 6 slides in the opposite direction. When the edge repair component 6 moves to the defective part, the control system starts the grinding motor 611, and the output shaft of the grinding motor 611 drives the first rotating shaft 66 to rotate, the first rotating shaft 66 drives the first gear 67 and the first grinding roller 65 to rotate, the first gear 67 drives the second gear 68 to rotate, the second gear 68 drives the second rotating shaft 610 to rotate, the second rotating shaft 610 drives the second grinding roller 69 to rotate, the first grinding roller 65 moves while grinding the cut surface of the metal part, and the second grinding roller 69 moves while grinding the cut surface of the finished metal part. After the cut surface of the metal part is polished, the edge detector 63 moving in the opposite direction performs a secondary detection on the polished edge, and repeats from then on until the edge of the metal part is corrected. The control system controls the electric gripper 72 to reset, and controls the L-shaped baffle 74 to descend through the second electric telescopic rod 73, and then uses the second electric conveying wheel 3 to transport the finished metal part.
