All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The deburring device for the powder injection molded green body of the present embodiment is used for deburring the powder injection molded green body.
As shown in fig. 1 and 2, the deburring apparatus for powder injection molded green bodies of the present embodiment includes: a magnetic force generating mechanism (not shown), a bracket 1, a suspension unit 2, a plurality of charging containers 3, and a plurality of grinding media 4 having magnetic permeability. The magnetic force generating mechanism is used for generating a magnetic field and can be magnetic grinding equipment on the market, and can generate a strong magnetic field with low rotation; one end of the bracket 1 is fixedly connected with the magnetic force generating mechanism, and the suspension unit 2 is rotatably connected to the other end of the bracket 1, in other words, the suspension unit 2 is connected with the other end of the bracket 1 and the suspension unit 2 can rotate relative to the bracket 1; the plurality of charging containers 3 are uniformly distributed on the suspension unit 2 along the circumferential direction, a plurality of grinding media 4 with magnetism conductivity are arranged in any charging container 3, the grinding media 4 can be stainless steel needles with radial dimensions of 0.3-0.5 mm and axial dimensions of 5-8 mm, the stainless steel needles can be made of one or more of 304 stainless steel, 316 stainless steel, 304L stainless steel or 316L stainless steel, the stainless steel has weak magnetism, and the stainless steel can rotate under the action of a magnetic field generated by a magnetic force generating mechanism so as to impact powder injection molding green bodies, thereby achieving the function of deburring the powder injection molding green bodies.
The working principle of the deburring device for the powder injection molding green body is as follows: when the charging container 3 is arranged on the bracket 1 through the suspension unit 2, a plurality of grinding media 4 in the charging container 3 are attracted by a low-rotation powerful magnetic field generated by the magnetic force generating mechanism and move around to strike the powder injection molding green compact, so that the deburring purpose of the powder injection molding green compact is realized; because the suspension unit 2 is rotatably connected with the bracket 1, when a plurality of grinding media 4 generate circumferential motion under the action of a revolving magnetic field, the suspension unit 2 can rotate relative to the bracket 1 under the drive of the grinding media 4,
thus, the burrs can fall down to the bottom of the charge container 3 due to centrifugal rotation after being impacted by the grinding media 4 off the green compact,
therefore, the influence of the fallen burrs on the movement of the grinding medium 4 can be avoided, the impact rate of the grinding medium 4 and other burrs which are not separated from the green body is improved, and the deburring efficiency and effect are improved.
More specifically, the charging container 3 of this embodiment has a smaller volume than the charging barrel of the conventional magnetic grinding apparatus, so that the phenomenon that the green bodies are mutually impacted and damaged due to the fact that too much powder is filled in the same charging container 3 to form the green bodies by injection can be avoided, and in addition, due to the smaller sectional area of the charging container 3, the travel of the grinding medium 4 along the circumferential direction under the action of the magnetic field is shorter, and therefore repeated movement of the grinding medium 4 in the charging container 3 is facilitated, and the deburring efficiency is improved. Since the volume of the single charge container 3 is small, in order to avoid inefficiency of the deburring device in a single operation, the present embodiment adopts a plurality of charge containers 3 simultaneously disposed at the suspension unit 2 to improve the production efficiency of a single operation of the magnetic force generating mechanism.
By adopting the scheme, the deburring device for the powder injection molding green body of the embodiment has the following advantages:
the burring device of this embodiment is used for carrying out the burring to the powder injection shaping unburned bricks, can make the burr just can get rid of at the initial stage, avoid the burr to become part of product through high temperature solidification, because the intensity of unburned bricks is less than the intensity of sintering back product, for avoid loading too many unburned bricks in charge container 3 and lead to the extrusion each other between the unburned bricks, the striking appears damaging, the volume control of charge container 3 of this embodiment is in certain within range, in addition, in order not to influence the burring efficiency of burring device, this embodiment has set up a plurality of charge containers 3 that can the simultaneous operation, guarantee that the burring device also can carry out the burring to a large amount of unburned bricks when single operation.
Specifically, as shown in fig. 1, the stand 1 of the present embodiment may include a base 11 and a support rod 12. The base 11 is fixedly connected with the magnetic force generating mechanism, one end of the supporting rod 12 is fixedly connected with the base 11, and the other end of the supporting rod 12 is rotatably connected with the suspension unit 2. Further, in order to improve the smoothness of rotation of the suspension unit 2 during the operation, the support rod 12 and the suspension unit 2 may be connected by using the bearing 5.
Specifically, when the loading container 3 is mounted on the suspension unit 2, there is a distance between its bottom and the base 11 of the support 1, which distance may be between 5 and 10 mm. This distance ensures that the charge container 3 does not get too small from the base 11, which would lead to interference of the bottom of the charge container 3 with the base 11 of the holder 1 when the suspension unit 2 is tilted at an angle, which would affect the rotation of the charge container 3 (or suspension unit 2), and that the distance ensures that the charge container 3 does not get too large from the base 11, which would lead to insufficient force of the low revolving magnetic field on the grinding medium 4 in the charge container 3, which would affect the deburring effect.
Specifically, as shown in fig. 2 and 3, the suspension unit 2 of the present embodiment is provided with a plurality of (e.g., 2 to 6) mounting holes 21 for accommodating the charging containers 3, the number of the plurality of mounting holes 21 is identical to the number of the plurality of charging containers 3, and a boss 31 may be provided on an outer wall of any one of the charging containers 3, and an outer dimension of the boss 31 is larger than an inner dimension of the mounting holes 21, so that the charging containers 3 may be suspended in the mounting holes 21 through the boss 31. More specifically, the suspension unit 2 may be a substantially uniform-thickness plate member in which a plurality of mounting holes 21 are uniformly provided (distributed in the circumferential direction), so that when the charging container 3 charged with an equal amount of green compact and grinding medium 4 is placed on each mounting hole 21, the suspension unit 2 is easily kept balanced from tilting to affect its rotation. Preferably, the mounting hole 21 of the present embodiment may be a circular through hole, the charging container 3 may be cylindrical, a boss 31 is provided near the opening of the charging container 3, the outer diameter of the portion of the charging container 3 for penetrating into the mounting hole 21 may be slightly smaller than the aperture of the mounting hole 21, and the outer diameter of the boss 31 is larger than the aperture of the mounting hole 21, so, when deburring is required, only the charging container 3 filled with the green compact and the grinding medium 4 needs to be inserted into the mounting hole 21, and the charging container 3 may be placed on the suspension unit 2 through the boss 31, at this time, the charging container 3 and the suspension unit 2 are not fixedly connected, but may be relatively movable.
With the above-described arrangement, when the grinding media 4 in the charging container 3 is moved by the magnetic force, the charging container 3 can also be rotated relative to the suspension unit 2 by the movement of the grinding media 4, that is, the plurality of charging containers 3 of the present embodiment can not only revolve with the suspension unit 2, but also the single charging container 3 can rotate relative to the suspension unit 2. By adopting the scheme, the deburring efficiency of the deburring device of the embodiment can be greatly improved. In addition, the charging container 3 and the suspension unit 2 of the present embodiment are not fixedly connected, so that the charging container 3 can be quickly placed on the suspension unit 2 or quickly removed from the suspension unit 2, which is beneficial to improving the convenience of the operation.
Specifically, as shown in fig. 4 to 7, the grinding media 4 of the present embodiment may be cylindrical or non-cylindrical. The grinding media 4 may comprise a body and at least one projection provided on the body, the end of the projection remote from the body having an included angle α that is less than or equal to 30 °. More specifically, the grinding media 4 of the present embodiment may be circular, triangular, drop-shaped, star-shaped, etc. in cross-section to accommodate the deburring requirements of green bodies of different shapes.
Specifically, the charging container 3 of the present embodiment may be further provided with a liquid medium, and the liquid medium may be one or more of water and an organic solution, and the organic solution may be ethanol. By adopting the scheme, the deburring effect of the device can be improved. Specifically, the grinding medium 4 is a small mass block which can be attracted by magnetic force, and is guided by the rotation direction of the magnetic force generating mechanism to rapidly rotate and drive the liquid medium to rotate, and in the charging container 3, the surface of the injection molding green compact with larger mass is impacted by a plurality of grinding mediums 4 and the liquid medium to generate the effects of grinding and removing burrs of the material.
Specifically, the total volume of the components contained in the charge container 3 of the present embodiment is not more than 70% of the volume of the charge container 3. Preferably, the green body in the charge vessel is calculated as volume ratio: grinding medium: liquid medium=20:5:40, the number of green bodies in the charging container 3 can be further reduced (even if only one green body is placed in one charging container 3) when the mass of the individual green bodies is large. In this way, the situation that the same charging container 3 is filled with excessive green bodies to cause the collision of the green bodies to each other, so that the green bodies are damaged is avoided, and meanwhile, the material in the charging container 3 is prevented from splashing.
Specifically, as shown in fig. 8, the deburring device for powder injection molding green bodies of the present embodiment further includes a motor 6, the motor 6 being provided on the bracket 1 to be connected to the suspension unit 2, the motor 6 being capable of driving the suspension unit 2 to rotate. Under the condition that no external force is applied, along with the movement of the grinding media 4, the rotation direction and rotation speed of the suspension unit 2 are mainly determined by the acting force of the revolving magnetic field generated by the magnetic force generating mechanism on the grinding media 4, and the suspension unit 2 is driven to rotate by adopting the motor 6, so that the rotation speed and the rotation direction of the suspension unit 2 can be adjusted according to the deburring requirement (the rotation direction can be adjusted to be opposite to the rotation direction of the revolving magnetic field), and the deburring effect of a green body can be improved. More specifically, the motor 6 can drive the suspension unit 2 to rotate slowly, so that the rotation direction of the suspension unit 2 is opposite to the direction of the magnetic force generating mechanism, and the speed difference generated by the two can increase the acceleration impact of the grinding medium 4 in the charging container 3, thereby improving the impact grinding effect of burrs on the surface of the green body.
The principles and embodiments of the present invention have been described in detail with reference to specific examples, which are provided to facilitate understanding of the method and core ideas of the present invention; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in accordance with the ideas of the present invention, the present description should not be construed as limiting the present invention in view of the above.
