Description

Technical Field

[0001] The invention relates to the technical field of magnesium ingot processing, and in particular to a magnesium ingot cutting and powder making device and a use method thereof. Background Art

[0002] Magnesium is a low-density, corrosion-resistant material that is mainly used in the automotive manufacturing industry, light industry, metallurgical industry, chemical industry, electronics industry, and instrument manufacturing industry. Magnesium chips, as a kind of crumbly magnesium, can be used in water treatment, reducing agent, flash powder, illuminant, catalyst, etc., and are an important industrial material. The raw material for the production of magnesium powder is magnesium ingots, which are obtained by cutting and grinding the magnesium ingots. The current magnesium ingot cutting method is to repeatedly cut the surface of the magnesium ingot with a tool, and at the same time use a press device to press the magnesium ingot to prevent it from loosening during the cutting process.

[0003] There are still some deficiencies in the prior art when chipping magnesium ingots: In the prior art, when the cylindrical cutter roller body drives the cutter head to cut chips, friction between the cutter head and the magnesium ingot generates heat, resulting in excessive temperature of the cutter head, which is easy to damage the cutter head and affect the subsequent cutting operation of the magnesium ingot. After magnesium ingot cutting is completed, magnesium chips are obtained. Magnesium chips are ground into magnesium powder. The particle size of magnesium powder is not uniform during the grinding process, which seriously affects the use of magnesium powder in the later stage.

The large-particle magnesium powder carried by the cold air is filtered by the filter screen 39 and falls into the discharge hole 19 along the return pipe 40, and is ground again to ensure the uniformity of the particle size of the magnesium powder. In addition, the trapezoidal block 41 can not only guide the magnesium powder, but also play a wind shield role for the return pipe 40, thereby preventing more air from leaking to the outside through the return pipe 40.

[0028] Example 2: Reference Fig.11 , improved on the basis of Example 1: a baffle 44 is fixed to the inner wall of the top of the air inlet pipe 36, and a plurality of tension springs 45 are fixed to one side of the baffle 44, and one end of the plurality of tension springs 45 are fixedly connected to the filter screen 39, and the filter screen 39 is raised to slide in the air inlet pipe 36 by the guide rail slider, and a pull rope 48 is provided on the side of the filter screen 39 away from the baffle 44, and one end of the pull rope 48 extends to the top of the air inlet pipe 36 and is fixed with a magnet block 46, and the magnet block 46 can slide on the top of the air inlet pipe 36 through the slider guide rail, and an electromagnet 47 matched with the magnet block 46 is fixed to the top of the air inlet pipe 36, and the magnetic attraction between the electromagnet 47 and the magnet block 46 is greater than the maximum tension value of the tension spring 45; when the filter screen 39 filters magnesium powder, the magnetic attraction between the magnet block 46 and the electromagnet 47 can be intermittently controlled by intermittently energizing and de-energizing the electromagnet 47, so that the filter screen 39 can be controlled to vibrate back and forth, which is used to shake off the magnesium powder attached to the filter screen 39, so as to facilitate grinding again in the later stage.

[0029] A method for using a magnesium ingot cutting and powder making device comprises the following steps: S1. Place the magnesium ingot on the top of the workbench 1, rotate the screw 6 to drive the U-shaped frame 5 to move downward, press the magnesium ingot through the rubber roller 8, and the limit plates 9 at both ends of the rubber roller 8 limit the magnesium ingot, and two gantries 4 are provided, so that the magnesium ingot can be limited, and then the magnesium ingot is pushed toward the cylindrical knife roller 11 through the cooperation of the hydraulic cylinder 2 and the push plate 3 to perform the magnesium ingot chip cutting operation. In addition, a plurality of rubber rollers 8 are provided. When the magnesium ingot chip cutting is completed, the magnesium ingot for the next chip cutting can be placed under other rubber rollers 8, so that the first chip cutting tool group 17 and the second chip cutting tool group 18 at different positions on the outer wall of the cylindrical knife roller 11 can perform alternate chip cutting operations, so as to avoid the first chip cutting tool group 17 and the second chip cutting tool group 18 from being too high in temperature, and ensure the service life of the first chip cutting tool group 17 and the second chip cutting tool group 18; S2, the grinding roller 26 and the rotating shaft 25 are driven to rotate by the motor, and the rotating shaft 25 drives the hollow rotating rod 10 and the cylindrical knife roller 11 to rotate through the synchronous wheel and the synchronous belt to perform chip cutting operation. During the chip cutting process, the coolant tank 12, the hollow rotating rod 10, and the cylindrical knife roller 11 form a coolant circulation system through the water pump 13, the liquid inlet pipe 14, the through hole 15 and the liquid outlet pipe 16, which is used to cool the first chip cutting tool group 17 and the second chip cutting tool group 18 on the outer wall of the cylindrical knife roller 11, and reduce the temperature of the first chip cutting tool group 17 and the second chip cutting tool group 18; S3, the first cutter head and the second cutter head in the first chip cutting tool group 17 and the second chip cutting tool group 18 are arranged in a staggered manner, so that the magnesium ingot can be cut into strip-shaped magnesium chips during chip cutting. At this time, the cooperation between the grinding roller 26 and the arc groove 28 can grind the magnesium chips. In addition, the movement of the grinding plate 23 is controlled by the rotation of the threaded rod 21, so as to control the distance between the grinding roller 26 and the arc groove 28, and the grinding particle size of the magnesium powder can be controlled; S4, start the vibration motor 43 to drive the sieve plate 30 to vibrate, so as to screen the magnesium powder on the sieve plate 30. The magnesium powder with small particle size falls on the discharge plate 29, and the magnesium powder is collected. The magnesium powder with larger particle size enters the air inlet box 34 through the cooperation of the sieve plate 30 and the return port 35. The blower 42 blows the air and the magnesium powder upward along the air inlet pipe 36. The coolant in the coolant tank 12 can just cool the passing air, and then the first chip cutting tool group 17 and the second chip cutting tool group 18 can be further cooled by the cold air. In addition, the large particle size magnesium powder carried by the cold air is filtered by the filter screen 39 and falls into the discharge hole 19 along the return pipe 40 to be ground again; S5. When the filter 39 filters the magnesium powder, the magnetic attraction between the magnet block 46 and the electromagnet 47 can be intermittently controlled by intermittently energizing and de-energizing the electromagnet 47, so that the filter 39 can be controlled to vibrate back and forth, so as to shake off the magnesium powder attached to the filter 39, so as to facilitate further grinding later. In addition, the trapezoidal block 41 can not only guide the magnesium powder, but also play a wind shield role for the return pipe 40, so as to prevent more air from leaking to the outside through the return pipe 40.

[0030] However, as is well known to those skilled in the art, the working principles and wiring methods of the blower 42, vibration motor 43, electromagnet 47, water pump 13 and hydraulic cylinder 2 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.
