A method for processing iron handicrafts comprises the following steps:

The first step is to place the iron raw material between the two clamping blocks 13, and the iron raw material is automatically clamped and fixed by the clamping limit mechanism;

In the second step, the servo motor 7 is started to make the rotating plate 35 rotate intermittently by ninety degrees. By setting the grinding mechanism, the auxiliary lifting mechanism and the blowing mechanism, the grinding of the iron raw material, the ultrasonic cleaning of the iron raw material after grinding, the air drying of the iron raw material after cleaning and the collection of the iron raw material after cleaning and air drying are completed in succession.

When the present invention is used, in the initial state, the second conductive block 37 and the second conductive rail 34 are in contact with each other, and the circuit of the electromagnet 20 is connected with magnetism, so that the iron material abuts against the bottom of the lower block 47 and is located between the two clamping blocks 13. Since the electromagnet 20 has a magnetic attraction to the iron material and the magnetic attraction is large enough, the iron material and the lower block 47 move upward. By setting the first guide rod 21 and the limit block 16, the first guide rod 21 and the limit block 16 move upward, the first spring 22 is compressed, and the lower block 47 moves upward to drive the clamping block 13 to move upward. By setting the abutment block 14, the two clamping blocks 13 are close to each other, the second spring 43 is compressed, and the two clamping blocks 13 close to each other clamp the iron material. The magnetic attraction of the electromagnet 20 to the iron material can also attract and fix the iron material.

By starting the servo motor 7, the hollow shaft 8 is intermittently rotated by ninety degrees. The rotation of the hollow shaft 8 drives the rotating plate 35 and the first fixed cylinder 17 and the second fixed cylinder 18 to rotate, thereby driving the clamped iron raw material to intermittently rotate by ninety degrees. When the hollow shaft 8 rotates by ninety degrees for the first time, the iron raw material rotates to the front of the grinding block 12, the planetary gear 25 rotates until it is about to mesh with the ring gear 38, the first conductive block 36 on the first fixed cylinder 17 rotates to contact with the first conductive rail 33, and the second conductive block 37 is still in contact with the second conductive rail 34. Through the controller (not shown), the circuit of the hydraulic cylinder 10 and the grinding motor 30 is connected, the grinding motor 30 is started to rotate the grinding shaft 31 and the grinding block 12, and the hydraulic cylinder 10 completes a telescopic action, so that the rotating grinding block 12 moves in the direction close to the iron raw material, thereby grinding the iron raw material. After grinding, the grinding block 12 moves in the direction away from the iron raw material and returns to the initial position;

After the grinding block 12 returns to the initial position, the servo motor 7 causes the hollow shaft 8 to continue to rotate ninety degrees. During this rotation, the first conductive block 36 is no longer in contact with the first conductive rail 33, and the second conductive block 37 is still in contact with the second conductive rail 34. The planetary gear 25 and the ring gear 38 are meshed with each other. The rotation of the planetary gear 25 drives the reciprocating screw 39 to rotate. The rotation of the reciprocating screw 39 causes the threaded block 40 to move downward from the highest position. By setting the through rod 41, the upper block 15 moves downward, thereby driving the ground iron raw material to move downward and gradually enter the ultrasonic cleaning box. 32, the upper block 15 moves downward to drive the block 19 to move downward, and the piston rod 46 is set to make the piston 45 slide downward, and the air is sucked into the second fixed cylinder 18 through the suction pipe 29 after being filtered. When the hollow shaft 8 continues to rotate 90 degrees (rotated 180 degrees from the initial position), the planetary gear 25 moves to the half position of meshing with the ring gear 38, and the threaded block 40 moves downward to the lowest position, so that the polished iron raw material moves downward to the lowest position and is completely immersed in the cleaning liquid in the ultrasonic cleaning box 32, thereby removing surface dirt;

Then the hollow shaft 8 rotates ninety degrees again. During the rotation, the planetary gear 25 and the ring gear 38 continue to mesh with each other. The rotation of the planetary gear 25 drives the reciprocating screw 39 to rotate. The rotation of the reciprocating screw 39 causes the threaded block 40 to move upward from the lowest position. By setting the through rod 41, the upper block 15 moves upward, thereby driving the iron raw material after grinding and cleaning to move upward and gradually away from the ultrasonic cleaning box 32. The upward movement of the upper block 15 drives the block 19 to move upward. By setting the piston rod 46, the piston 45 slides upward, and the air sucked into the second fixed cylinder 18 is squeezed into the box body 4 through the second ventilation pipe 28, the hollow shaft 8 and the first ventilation pipe 5 times, and is sprayed out through the nozzle on the box body 4. The sprayed air can clean the iron raw material after grinding and cleaning. Auxiliary drying is performed. When the hollow shaft 8 rotates another 90 degrees (rotated 270 degrees from the initial position), the planetary gear 25 moves to no longer mesh with the ring gear 38, and the threaded block 40 moves upward to the highest position, so that the iron raw material after grinding and cleaning moves upward to the highest position and is located directly above the collection box 6. The piston 45 slides upward to the initial position, but at this time the second conductive block 37 is no longer in contact with the second conductive rail 34, and the circuit of the electromagnet 20 is no longer connected, so that the iron raw material is no longer subjected to magnetic attraction. The elastic force generated by the compression of the first spring 22 and the second spring 43 causes the two clamping blocks 13 to move away from each other, and the iron raw material is no longer clamped and fixed, and falls into the collection box 6 due to gravity (there are buffer protection measures in the collection box 6);

Finally, the servo motor 7 causes the hollow shaft 8 to rotate 90 degrees again to return to the initial position, so that the second conductive block 37 contacts the second conductive rail 34 again, and the circuit of the electromagnet 20 is connected again, and this cycle repeats.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
