In order to make the guardrail metal tubes beautiful and safe enough during use and prevent burrs on the surface of the metal tubes from scratching people, the metal tubes need to undergo necessary polishing and grinding. When making metal tubes for guardrails, it is often necessary to grind large quantities of metal pipes of the same specifications. The existing metal processing and grinding machines include automatic loading, feeding, grinding and unloading. The working principle is: the motor drives the polishing wheel or the grinding belt to rotate at a high speed, and the high-speed rotating polishing wheel or the grinding belt rubs against the surface to be polished, thereby achieving the purpose of removing burrs, paint pollution, oxide layer and shallow marks on the surface of metal pipes.

In this metal processing and polishing production line, the loading arm tightens the pull rope while flipping, and the pull rope is pulled up by force. The ejected rod passes through the baffle and falls on the receiving tray to drain the polishing liquid. The excess polishing liquid flows from the water outlet into the return pipe and sprays to the hollow sealing box through the overflow valve to clean the frosting cylinder on the inner wall of the hollow sealing box to reduce dust residue.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0020] Reference Figure 1-Figure 9 A metal processing and grinding production line includes a grinding box 1 filled with magnetic abrasive and polishing liquid, and also includes: a loading rack 2 fixedly installed on the grinding box 1, and rods 7 are stacked in the loading rack 2; a component box 3 sealedly installed in the grinding box 1, and a magnetic mechanism is arranged in the component box 3; a driving shaft 5 rotatably installed in the grinding box 1, one end of the driving shaft 5 is externally connected to a first motor 4, and the other end of the driving shaft 5 is provided with a magnetic disk 6, and the rods 7 are adsorbed on the magnetic disk 6.

[0021] Among them, see Figure 6The driving shaft 5 includes: two symmetrically arranged inclined plates 501, a connecting shaft 502 is rotatably installed between the two inclined plates 501, and a first connecting shaft 503 is fixedly installed on one side of the two inclined plates 501 away from the connecting shaft 502, and the two first connecting shafts 503 are respectively connected to the first motor 4 and the magnetic mechanism.

[0022] Through the arrangement of the above structure, the first motor 4 drives the first connecting shaft 503 and the magnetic mechanism to run simultaneously, and the rod 7 is adsorbed on the first connecting shaft 503 on one side. The disordered magnetic field generated by the magnetic mechanism makes the magnetic abrasive in the grinding box 1 constantly contact with the metal rod, thereby improving the surface finish and flatness of the workpiece, and the rod 7 is immersed in the polishing liquid, and the dust generated by its grinding will not escape, reducing the harm to the staff.

[0023] See also Figure 1 and Figure 3 and Figure 4 , wherein the magnetic mechanism includes: a bottom plate 8 fixedly installed in the component box 3, an L-shaped movable plate 9 is slidably installed on the bottom plate 8, a turntable 10 is rotatably installed on the L-shaped movable plate 9, and a ring-arranged magnet 11 is fixedly installed on the turntable 10; a worm wheel 12 and a worm 13 are rotatably installed on the side of the L-shaped movable plate 9, a first connecting shaft 503 on one side is coaxially installed in the worm 13, and the worm wheel 12 and the turntable 10 are connected through a bevel gear 14.

[0024] See also Figure 5 A keyway 5031 is provided on the first connecting shaft 503, and a latch 1301 adapted to the keyway 5031 is fixedly installed on the inner wall of the worm 13; an eccentric rod 1201 is fixedly installed on the worm wheel 12, and a connecting arm 15 is rotatably connected between the eccentric rod 1201 and the base plate 8.

[0025] See also Figure 1 and Figure 6 A connecting seat 504 is fixedly mounted on the connecting shaft 502 , a reciprocating rod 505 is rotatably mounted on the connecting seat 504 , the reciprocating rod 505 is slidably mounted on the component box 3 , and the magnetic disk 6 is fixedly mounted on the reciprocating rod 505 .

[0026] Through the arrangement of the above structure, the first motor 4 drives the first connecting shaft 503 to rotate and transmits the rotational force to the worm 13, and the worm 13 drives the meshing worm wheel 12 to rotate. A first extension shaft 1202 extending to the bottom of the turntable 10 is coaxially installed on the worm wheel 12, and a second extension shaft 1001 is also coaxially installed on the turntable 10. The bevel gear 14 is respectively fixedly installed on the first extension shaft 1202 and the second extension shaft 1001 and meshingly connected to transmit the rotational power to rotate the turntable 10. On the one hand, the turntable 10 drives the magnet 11 to rotate to generate a disordered magnetic field, so that the magnetic abrasive in the grinding box 1 rotates at a high frequency; on the other hand, the rotating worm wheel 12 is affected by the connecting arm 15 and slides back and forth on the bottom plate 8, thereby increasing the range of the magnetic field and improving the grinding efficiency.

[0027] At the same time, when the first connecting shaft 503 transmits power, the connecting seat 504 installed on the connecting shaft 502 drives the reciprocating rod 505 to slide back and forth on the component box 3, increasing the contact between the rod 7 and the magnetic abrasive, thereby improving the grinding efficiency.

[0028] See also Figure 1 and Figure 7 and Figure 8 A hollow sealed box 16 is fixedly installed on the component box 3, and an electromagnetic coil 17 and an automatic control unit are fixedly installed in the hollow sealed box 16. The electromagnetic coil 17 and the automatic control unit are electrically connected. A grinding cylinder 18 is rotatably installed in the hollow sealed box 16, and the grinding cylinder 18 is coaxially arranged with the electromagnetic coil 17; a first bevel gear 29 is fixedly installed at one end of the grinding cylinder 18, and a second bevel gear 30 is coaxially installed on the turntable 10, and the first bevel gear 29 is meshingly connected with the second bevel gear 30.

[0029] The automatic control unit includes a timer, a controller, a circuit board 19, and an infrared tube 20. The automatic control unit is connected to a power supply, and the controller is respectively connected to the timer and the circuit board 19 signals. The circuit board 19 is fixedly mounted on the side of the electromagnetic coil 17 away from the disk 6, and the infrared tube 20 is welded on the circuit board 19.

[0030] Through the arrangement of the above structure, the rod 7 being processed by the magnetic disk 6 slides in the hollow sealed box 16. On the one hand, the rod 7 contacts the grinding cylinder 18 on the inner wall of the hollow sealed box 16, and the surface of the rod 7 is polished by the grinding cylinder 18 during the reciprocating sliding of the rod 7. At the same time, the turntable 10 transmits the rotational force to the second bevel gear 30 when rotating, and the second bevel gear 30 drives the meshing first bevel gear 29 to rotate, and the rotating first bevel gear 29 drives the coaxially fixed grinding cylinder 18 to rotate. The radial grinding of the rod 7 is increased to improve the smoothness of the rod 7; secondly, after polishing for a certain period of time, the controller energizes the electromagnetic coil 17 to generate magnetism to adsorb the rod 7 originally adsorbed on the magnetic disk 6 to the center of the hollow sealing box 16, and the rod 7 is separated from the magnetic disk 6. The magnetic disk 6 can continue to adsorb the next rod 7 that needs to be polished, thereby realizing automatic loading. At the same time, when the rod 7 passes through the middle of the infrared tube 20, a high frequency electric frequency will be output, so that the rod 7 can be quickly ejected from the electromagnetic coil 17, thereby realizing rapid unloading.

[0031] It should be noted that the model of the timer is TM1637 and the controller is a PLC controller, both of which are existing mature technologies and will not be described in detail; and the timer, controller, circuit board 19, and infrared tube 20 form an effective electrical connection through existing technology to achieve intermittent power supply to the electromagnetic coil 17 at a preset frequency.

[0032] The length of the rod 7 is smaller than the distance between the magnetic disk 6 and the hollow sealing box 16 , and the staff can also manually insert the rod 7 into the hollow sealing box 16 .

[0033] See also Figure 1 and Fig.10 A liquid storage tank 31 is provided in the polishing box 1. The liquid storage tank 31 is located at the lower part of the polishing box 1. The top is connected to the component box 3 through an isolation net 32. The isolation net 32 ​​is located on the side of the hollow sealed box 16 away from the magnetic disk 6. A circulating air bag 35 is provided at the bottom of the bottom plate 8. The circulating air bag 35 is connected to the bottom of the liquid storage tank 31 through a first connecting pipe 34. The circulating air bag 35 is connected to the component box 3 through a second connecting pipe 36. The second connecting pipe 36 is located on the side of the hollow sealed box 16 close to the magnetic disk 6.

[0034] A filter screen 33 is provided in the liquid storage bin 31 .

[0035] The mesh opening of the isolation net 32 ​​ensures that the rod 7 does not fall and is not stuck on the isolation net 32. At the same time, the metal particles in the polishing liquid can also fall freely.

[0036] Both the first connecting tube 34 and the second connecting tube 36 are provided with a one-way valve. The one-way valve on the first connecting tube 34 allows the polishing liquid to only enter the circulating air bag 35 , and the one-way valve on the second connecting tube 36 allows the polishing liquid to only enter the second connecting tube 36 from the circulating air bag 35 .

[0037] During the grinding process, when the electromagnetic coil 17 generates an electromagnetic force to eject the rod 7, the metal particles contained in the polishing liquid in the component box 3 will also move forward under the action of the electromagnetic ejection force, that is, move towards the isolation net 32. The function of the isolation net 32 ​​is to prevent the rod 7 from falling into the liquid storage tank 31. However, when the electromagnetic ejection force disappears, a part of the metal particles contained in the polishing liquid will pass through the isolation net 32 ​​and fall into the liquid storage tank 31, and then fall on the filter net 33.

[0038] When the L-shaped movable plate 9 moves back and forth, it will periodically squeeze the circulating airbag 35, and the polishing liquid in the liquid storage tank 31 will be transported to the component box through the circulating airbag 35 through the second connecting pipe 36, so that the polishing liquid in the liquid storage tank 31 will circulate after being filtered through the filter net 33 and leaving the metal particles in the rear liquid storage tank 31.

[0039] At the same time, through the position of the second connecting tube 36 and the isolation net 32, the polishing liquid flows out from the second connecting tube 36, enters the isolation net 32, and circulates, cooperating with the electromagnetic force ejection of the electromagnetic coil 17 in the hollow sealing box 16, and further drives the metal particles in the polishing liquid to move toward the isolation net 32, thereby improving the filtering effect of the metal particles in the polishing liquid.

[0040] See also Figure 1 and Figure 2 The loading rack 2 includes: a loading plate 201 obliquely installed on the polishing box 1, a second connecting shaft 202 is rotatably installed on one side of the loading plate 201 located in the polishing box 1, torsion springs 205 are fixedly connected between the two ends of the second connecting shaft 202 and the loading plate 201, and equidistantly arranged loading arms 203 are fixedly installed on the second connecting shaft 202; a second motor 204 is fixedly installed on the outer side of the loading plate 201, the output end of the second motor 204 is fixedly connected to the second connecting shaft 202, and the input end of the second motor 204 is connected to the controller signal.

[0041] Through the arrangement of the above structure, when the controller energizes the electromagnetic coil 17, the second motor 204 is also intermittently connected to the circuit and drives the second connecting shaft 202 to rotate. The second connecting shaft 202 drives the loading arm 203 to flip and transfer the rod 7 to the polishing box 1 and it is adsorbed and fixed by the magnetic disk 6.

[0042] See also Figure 1 and Fig. 9A door frame 21 is fixedly installed in the polishing box 1, and a pull rope 22 is slidably installed on the door frame 21. A spoiler 23 is fixedly installed on one end of the pull rope 22, and the spoiler 23 is slidably installed on the component box 3. A material receiving assembly is arranged between the spoiler 23 and the component box 3; one end of the second connecting shaft 202 extends out of the loading plate 201 and is rotatably connected to the inner wall of the polishing box 1, and the other end of the pull rope 22 is fixedly connected to the loading arm 203 on the second connecting shaft 202.

[0043] The material receiving assembly includes: a connecting seat 24 fixedly mounted on the baffle 23, on which a first swing arm 25 is rotatably mounted; a supporting arm 26 fixedly mounted on the component box 3, on which two symmetrically arranged second swing arms 27 are rotatably mounted, and a material receiving tray 28 is rotatably mounted between the two second swing arms 27; the first swing arm 25 is rotatably connected to the adjacent second swing arms 27; the material receiving tray 28 is provided with a water outlet 2801 and a return pipe 2802 matched with the water outlet 2801, the output end of the return pipe 2802 faces the hollow sealing box 16, and an overflow valve is fixedly installed in the return pipe 2802.

[0044] Through the arrangement of the above structure, the loading arm 203 tightens the pull rope 22 while flipping, and the pull rope 22 is forced to pull up the baffle 23, and the ejected rod 7 passes through the baffle 23 and falls on the receiving tray 28 to drain the polishing liquid. The excess polishing liquid flows into the return pipe 2802 from the water outlet 2801 and is sprayed toward the hollow sealing box 16 through the overflow valve, so as to clean the frosted belt 18 on the inner wall of the hollow sealing box 16 and reduce dust residue.
