Description

Technical Field

[0001] The present application relates to the field of metallurgy technology, and in particular to a metal powder processing and grinding device. Background Art

[0002] In the field of metallurgy, metal powder is a basic raw material. It is made into fine particles by mechanical grinding, chemical methods or physical methods. The mainstream method for grinding metal powder is ball mill. For example, a pre-crushing and feeding device of a metal powder ball mill disclosed in "CN201810862095.6" is provided with a sealed drum, multiple steel balls and metal raw materials (large in volume) built in. When rotating, the steel balls are driven to a high position and finally allowed to fall freely and hit the metal material heavily, playing the role of crushing and grinding. However, this method also has certain shortcomings. For example, in a relatively closed space, the heat of metals colliding with each other is difficult to dissipate, and it cannot be cooled evenly, which may affect the mechanical properties of the metal powder. The metal raw materials tumble with the drum, which easily causes the already ground particles to mix with the unground particles, prolonging the grinding time and reducing the working efficiency of the device. At the same time, this is not conducive to accurately controlling the size of the metal powder and has poor adaptability. Therefore, this patent is committed to overcoming the above-mentioned shortcomings and designing and developing a metal powder processing and grinding device. Summary of the Invention

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. This device has been redesigned to have the function of continuously grinding metal materials. A support seat is provided to support the blanking plate, and a second motor is provided to drive the blanking plate, so that the metal material can automatically fall onto the upper surface of the blanking plate along the feed hopper under the action of gravity. The fixed block is driven to rotate by a first motor, thereby driving the multiple groups of connecting columns and steel balls that are movably sleeved inside the fixed block to rotate around the axis of the fixed block. The fixed ring, connecting frame and roller installed on the top of the inner wall of the box are used to support the movable seat, so that the connecting columns and steel balls can move up and down. A movable groove is provided at the bottom of the movable seat, so that when the movable seat rotates relative to the roller, it is relative to the roller. As for movement, during the rotation of the moving seat, the roller moves relatively along the bottom of the moving seat to the inside of the drop groove, and the vertical design of the drop groove is used to form a huge support drop between the roller and the moving seat. The moving seat, which has lost the support of the solid part, moves downward rapidly under the elastic force of the spring and the gravity of the steel ball, so that the steel ball quickly hits the metal material on the surface of the blanking plate, thereby crushing the metal material. Then, through the stabilizing groove and the reset groove, the moving seat is reset under the support of the roller during the continued rotation, and the spring is re-compressed to store energy, so that the steel ball can repeatedly hammer the blanking plate, and cooperate with the reverse rotation of the blanking plate to fully hammer, grind and crush the material.

[0019] 2. Then, through the incremental inclination design of the top of the blanking plate with a low middle and high periphery, centrifugal force is generated during the rotation of the blanking plate, pushing the metal material to the outside of the blanking plate surface, dispersing the material, and increasing the contact area between it and the steel ball. At the same time, the ground metal powder is filtered using a filter screen fixedly installed on the outside of the blanking plate, so that the metal powder ground to the right size can be filtered in time, thereby improving the utilization rate of the blanking plate. The metal powder thrown to the edge of the blanking plate by the centrifugal force begins to fly due to the vibration generated by the heavy hammering of the steel ball on the blanking plate, and returns to the hammering area of ​​the steel ball along the inclined surface of the top of the blanking plate, thereby effectively improving the working efficiency of the device.

[0020] 3. This device is also designed with an air cooling system to cool the surface grinding workpiece of the blanking plate. By installing multiple sets of inclined plates with inclined designs at the bottom of the limit plate and air troughs at the top of the limit plate, upward negative pressure is generated, thereby increasing the air circulation efficiency near the blanking plate, and continuously absorbing the heat generated by the hammering of steel balls and grinding of metal materials upward and discharging it along the heat dissipation port. A through hole is opened in the middle of the limit plate, and an air hole is opened in the middle of the fixed block. The hot air enters the air hole and the feed hopper through the through hole and the bellows, forming a "chimney effect", thereby accelerating the rate at which the hot air rises, thereby effectively ensuring the cooling effect of the device.

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] See also Figure 1-Figure 7 This embodiment discloses a metal powder processing and grinding device, including a box body 1, a feed hopper 2, and

[0033] The fixed block 12 is rotatably mounted on the upper portion of the inner wall of the box body 1. The internal movable sleeve of the fixed block 12 is connected to multiple groups of connecting columns 14. The bottom of the connecting column 14 is fixedly mounted with a steel ball 15. The outer side of the box body 1 is provided with a motor 4. The motor 4 drives the fixed block 12 to rotate. The outer surface of the connecting column 14 is fixedly mounted with a limit plate 16. A spring 19 is elastically connected between the fixed block 12 and the connecting column 14. The top of the connecting column 14 is fixedly connected to the movable seat 8. The bottom of the movable seat 8 is provided with multiple groups of movable grooves 9.

[0034] The support base 20 is fixedly mounted on the bottom of the inner wall of the box body 1. The bottom of the support base 20 is mounted with a second motor 21. The output shaft of the second motor 21 is connected to a blanking plate 22 via a spline transmission. The outer surface of the blanking plate 22 is fixedly mounted with a filter screen 24.

[0035] A fixing ring 7 is fixedly installed on the top of the inner wall of the box body 1, and a plurality of connecting frames 10 are fixedly connected to the bottom of the fixing ring 7. A roller 11 is rotatably installed on the inner side of the connecting frame 10, and the outer surface of the roller 11 rolls against the bottom of the movable seat 8;

[0036] This device has been redesigned to have the function of continuously grinding metal materials. A support seat 20 is provided to support the blanking plate 22, and a motor 21 is provided to drive the blanking plate 22, so that the metal material can automatically fall onto the upper surface of the blanking plate 22 along the feed hopper 2 under the action of gravity. A motor 14 is provided to drive the fixed block 12 to rotate, thereby driving the multiple groups of connecting columns 14 and steel balls 15 that are movably sleeved inside the fixed block 12 to rotate around the axis of the fixed block 12. The fixed ring 7, the connecting frame 10 and the roller 11 installed on the top of the inner wall of the box body 1 are used to support the movable seat 8 in rotation, so that the connecting column 14 and the steel ball 15 can move up and down. A movable groove 9 is provided at the bottom of the movable seat 8 so that when the movable seat 8 rotates relative to the roller 11, it rotates with the roller 1 1 relative motion, during the rotation of the movable seat 8, the roller 11 moves relative to the bottom of the movable seat 8 to the inside of the drop groove 91. The vertical design of the drop groove 91 forms a huge support drop of the roller 11 on the movable seat 8. The movable seat 8, which has lost the support of the solid part, moves downward rapidly under the elastic force of the spring 19 and the gravity of the steel ball 15, so that the steel ball 15 quickly hits the metal material on the surface of the blanking plate 22, thereby crushing the metal material. Then, through the stabilizing groove 92 and the reset groove 93, the movable seat 8 is reset under the support of the roller 11 during the continued rotation, and the spring 19 is re-compressed to store energy, so that the steel ball 15 can repeatedly hammer the blanking plate 22. Cooperating with the reverse rotation of the blanking plate 22, the material can be fully hammered, ground and crushed.

[0037] Then, through the incremental inclination design of the top of the blanking plate 22 with a low middle and high periphery, centrifugal force is generated during the rotation of the blanking plate 22, pushing the metal material to the outside of the surface of the blanking plate 22, dispersing the material, and making its contact area with the steel ball 15 larger. At the same time, the ground metal powder is filtered using the filter screen 24 fixedly installed on the outside of the blanking plate 22, so that the metal powder ground to the right size can be filtered in time, thereby improving the utilization rate of the blanking plate 22. The metal powder thrown to the edge of the blanking plate 22 by the centrifugal force begins to jump up due to the vibration generated by the heavy hammering of the steel ball 15 on the blanking plate 22, and returns to the hammering area of ​​the steel ball 15 along the inclined surface at the top of the blanking plate 22, thereby effectively improving the working efficiency of the device.

[0038] Among them, the right side of the box body 1 is fixedly installed with a protective shell 3, the motor 1 4 is fixedly installed at the bottom of the protective shell 3, the output shaft of the motor 1 4 is fixedly installed with a gear 1 6 located inside the protective shell 3, and the outer surface of the fixed block 12 is fixedly installed with a gear 2 13, and the gear 1 6 is meshed with the gear 2 13;

[0039] The protective shell 3 is arranged on the outside of the box body 1, and drives the fixed block 12 to rotate through gear 1 6 and gear 2 13, so that the connecting column 14 and the steel ball 15 can be driven to rotate, and move up and down with the cooperation of the moving seat 8 and the roller 11, hammering and grinding the metal material on the surface of the blanking plate 22.

[0040] Among them, a plurality of heat dissipation vents 5 are provided on the central circumference of the outer surface of the box body 1, a group of through holes 26 and a plurality of air ducts 27 are provided in the middle and periphery of the limiting plate 16, a plurality of inclined plates 17 are fixedly connected to the outer edge of the bottom of the limiting plate 16, a through-type air duct 25 is provided in the middle of the fixed block 12, a bellows 18 is fixedly connected between the fixed block 12 and the limiting plate 16, and the feed hopper 2 is fixedly installed on the top of the box body 1, and the feed hopper 2 is adapted to pass through the inside of the movable seat 8 and the air duct 25;

[0041] This device is also designed with an air cooling system to cool the surface grinding workpiece of the blanking plate 22. By installing multiple sets of inclined plates 17 with inclined designs at the bottom of the limiting plate 16 and air grooves 27 opened at the top of the limiting plate 16, upward negative pressure is generated to increase the air circulation efficiency near the blanking plate 22, and the heat generated by the steel balls 15 hammering and grinding the metal materials is continuously absorbed upward and discharged along the heat dissipation port 5. A through hole 26 is opened in the middle of the limiting plate 16, and an air hole 25 is opened in the middle of the fixed block 12. The hot air enters the air hole 25 and the feed hopper 2 through the through hole 26 and the bellows 18, forming a "chimney effect", thereby accelerating the rate at which the hot air climbs upward, thereby effectively ensuring the cooling effect of the device.

[0042] The movable groove 9 includes a drop groove 91, a stabilizing groove 92 and a reset groove 93. The drop groove 91 is vertically arranged, the stabilizing groove 92 is horizontally arranged and higher than the bottom of the movable seat 8, and the reset groove 93 is inclined. The drop groove 91, the stabilizing groove 92 and the reset groove 93 are distributed in a clockwise direction along the outer surface of the movable seat 8.

[0043] like Figure 7 As shown, when the movable seat 8 rotates in the direction of the arrow on its surface, the roller 11 provides rolling support for the bottom of the movable seat 8. When the roller 11 moves relatively to the drop groove 91, the vertical design of the drop groove 91 causes the movable seat 8 to drop rapidly from a high position to the lowest position. At the same time, under the elastic force of the spring 19, the force with which the steel ball 15 hammers downward on the metal material on the surface of the blanking plate 22 is increased.

[0044] Among them, the rotation direction of the fixed block 12, the connecting column 14 and the movable seat 8 is counterclockwise. When the roller 11 is separated from the movable groove 9 and rolls against the bottom of the movable seat 8, the spring 19 is compressed to the limit;

[0045] The rotation direction of the fixed block 12, the connecting column 14 and the movable seat 8 is counterclockwise, which is equivalent to the rotation direction of the roller 11 being clockwise. In the reference system of relative motion: the roller 11 moves along the bottom of the movable seat 8 toward the drop groove 91, the stabilization groove 92 and the reset groove 93 in sequence. When the roller 11 moves relatively to the reset groove 93, the movable seat 8 as a whole is supported by the roller 11 again and resets upward.

[0046] Among them, the bottom of the blanking plate 22 is provided with a slide groove, and the spline on the outer surface of the output shaft of the motor 2 21 is adapted to the slide groove, so that the blanking plate 22 can move up and down relative to the motor 2 21;

[0047] When the steel ball 15 hammers the blanking plate 22 downward, the blanking plate 22 needs to leave enough sinking space to cope with the energy impact of the steel ball 15 on the one hand, and needs to leave a buffer space on the other hand. When the blanking plate 22 is hammered by the steel ball 15 and vibrates, the material can be loosened upward to increase the contact area between the metal material and the steel ball 15.

[0048] Among them, the top of the motor 21 is fixedly connected with a buffer pad 23, and the bottom of the blanking plate 22 abuts against the buffer pad 23, and the buffer pad 23 is made of a rubber block;

[0049] When the blanking plate 22 is hammered by the steel ball 15, it moves downward. At this time, the buffer pad 23 is squeezed and deformed, and absorbs most of the energy from the steel ball 15. The remaining energy is used for the blanking plate 22 to vibrate up and down to shake off the metal material.

[0050] The middle of the top surface of the blanking plate 22 is horizontally arranged, and the height of the top of the blanking plate 22 is gradually increased from the middle to the edge. The distance between the steel ball 15 and the surface of the blanking plate 22 is less than the depth of the moving groove 9.

[0051] The top of the blanking plate 22 is designed to be low in the middle and high around the edges, so that the centrifugal force generated by the blanking plate 22 is partially offset by the gravity component force generated by the material on the surface of the blanking plate 22 along the inclined direction, which can effectively maintain the retention time of the material in the hammering area on the surface of the blanking plate 22.

[0052] The outer surfaces of the fixed ring 7 and the movable seat 8 are adapted to each other. When the movable seat 8 moves to the lowest point, the top of the movable seat 8 is higher than the bottom of the fixed ring 7.

[0053] During the up and down movement of the movable base 8 , the fixed ring 7 provides guidance and adaptation, and the connecting frame 10 and the roller 11 provide rotational support for the movable base 8 .

[0054] The rotation direction of the blanking plate 22 is opposite to that of the fixed block 12, and the steel ball 15 is made of tungsten alloy;

[0055] The blanking plate 22 moves in opposite directions to the fixed block 12 , which can improve the dispersion of the metal material on the surface of the blanking plate 22 , while increasing the contact area between the metal material and the steel balls 15 , thereby improving the grinding efficiency of the device.

[0056] Working principle:

[0057] When the device is working, the roller 11 is located at the bottom of the moving seat 8 and is not in contact with the moving groove 9. At this time, the connecting column 14, the steel ball 15 and the moving seat 8 are in the highest position. The metal material is put along the feed hopper 2 and passes through the air hole 25, the bellows 18 and the through hole 26 and falls on the upper surface of the blanking plate 22. The motor 21 is started and drives the blanking plate 22 to rotate clockwise, and the metal material is dispersed by centrifugal force. At the same time, the motor 1 4 is started and drives the fixed block 12 to rotate clockwise through the gear 1 6 and the gear 2 13, which drives the connecting column 14, the steel ball 15, the limit plate 16 and the moving seat 8 to rotate clockwise. Figure 1 、 Figure 4 As shown, since the fixed ring 7 is fixed, the movable seat 8 performs a circular motion relative to the connecting frame 10 and the roller 11. At this time, the roller 11 passes through the drop groove 91, the stabilizing groove 92 and the reset groove 93 in the form of relative motion:

[0058] Hammering stage: The roller 11 moves relative to the bottom of the movable seat 8 through the drop groove 91. Since the drop groove 91 is designed to be vertical, when the movable seat 8 rotates, it instantly loses the rolling support of the roller 11 and falls rapidly under the action of the rebound force of the spring 19 and the gravity of the connecting column 14 and the steel ball 15. As a result, the steel ball 15 hammers heavily on the surface of the blanking plate 22 to crush the metal material on the surface of the blanking plate 22.

[0059] Rotation stage: When the roller 11 moves relatively to the stable groove 92, the fixed block 12 drives the steel ball 15 to rotate as a whole. The height of the steel ball 15 remains unchanged during this stage, and the steel ball 15 stirs the material on the surface of the blanking plate 22;

[0060] Reset stage: When the roller 11 moves relatively to the reset groove 93 and supports the movable seat 8 as a whole on the inclined surface of the reset groove 93, the movable seat 8, the connecting column 14 and the steel ball 15 move upward and reset, and the spring 19 is recompressed. At this time, the movable seat 8 rotates again to the position where its bottom rolls against the outer surface of the roller 11;

[0061] Every time the steel ball 15 hits the blanking plate 22, the blanking plate 22 moves downward and compresses the buffer pad 23 for cushioning. At the same time, the blanking plate 22 vibrates as a whole, shaking off the metal material, and the rotating buffer pad 23 generates centrifugal force, driving the material toward the outer edge of the upper surface of the blanking plate 22. At this time, the metal powder that is hammered by the steel ball 15 and reaches the standard volume is filtered through the filter screen 24 and falls down, while the metal material that does not meet the volume standard falls back to the hammering area of ​​the steel ball 15 under the vibration of the blanking plate 22 for re-grinding.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
