Description

Technical Field

[0001] The invention relates to a hard alloy material processing device, in particular to a mixing device for hard alloy material processing. Background Art

[0002] The forming process of cemented carbide rods is to add tungsten carbide (WC) and cobalt (Co) and other raw materials in proportion, refine them through a ball mill to ensure uniform powder, and mix the refined cemented carbide material with a forming agent, then dry to remove moisture. The material after moisture removal is pressed into shape and sintered at high temperature. The sintered workpiece is ground and polished before being put into storage.

[0003] When mixing materials in a conventional device, alloy powder and molding agent are usually added to a mixing tank for mixing. However, with this mixing method, since the mass of the alloy powder is often greater than that of the solution and the molding agent, part of the alloy powder will sink to the bottom. Therefore, the prior art increases the strength of the stirring blades and the output strength of the motor to move the powder deposited at the bottom to the top. What's more, a gas ejection structure is provided at the bottom of the mixing device to stir the alloy powder by gas. However, in fact, the weight of the alloy powder is relatively heavy, especially at the bottom where more powder is deposited. It is often difficult to guide the powder at the bottom upward by gas, and the partially agglomerated powder is not only likely to hinder the mixing and put a large pressure on the stirring rod in the lower part, but also easily causes the temperature rise caused by the mixing of the powder to accumulate in the lower part, which is likely to affect the chemical composition of the powder, thereby causing a certain feature of the formed workpiece to fail to meet the standard.

[0004] Therefore, this case aims to provide a mixing equipment for cemented carbide material processing, which can provide sufficient stirring intensity in the lower part of the equipment, and at the same time can have a certain agitation effect on the powder during stirring, so that more bottom powder can be added to the middle and upper stirring areas, thereby improving the mixing effect and ensuring the uniformity of the mixing temperature. Summary of the invention

The lower stirring rod is clamped with the upper stirring rod. The outer side of the lower stirring rod is provided with stirring blades. The outer sides of the lower stirring rod and the upper stirring rod are provided with an outer sleeve ring. The downward flow structure includes an annular table located below the stirring blade, the annular table is connected to the lower stirring rod and rotates with the lower stirring rod, a plurality of groups of movable pressure frames are arranged at the upper end of the outer edge of the annular table, a pressure rod is arranged on the inner side of the movable pressure frame, and when the annular table rotates, the pressure rods in the plurality of movable pressure frames are driven to lift up, thereby poking the alloy powder at the bottom upward.

[0007] As a further improvement, the limiting cylinder comprises a circular cavity cylinder for accommodating the lower stirring rod, a cushion seat is arranged at the bottom of the circular cavity cylinder, and a plurality of annular cushions are arranged on the inner circumference of the circular cavity cylinder.

[0008] As a further improvement, the annular gasket includes a clamping ring that fits the lower stirring rod, and a limit strip is arranged on the outer side of the clamping ring, and the limit strip is fixedly connected to the inner side wall of the circular cavity.

[0009] As a further improvement, a hexagonal screw is integrally formed at the bottom of the lower stirring rod, and a hexagonal slot is provided at the upper end of the upper stirring rod. After the lower stirring rod is installed, the hexagonal screw is clamped in the hexagonal slot.

[0010] As a further improvement, the outer ring includes a middle guide seat sleeved on the outside of the inner hexagonal groove, and a plurality of connecting ribs are arranged on the outside of the middle guide seat, and all the connecting ribs are installed on the outer guide seat.

[0011] As a further improvement, the annular platform comprises an outer connecting plate fixed on the outer side of the lower stirring rod, and an annular ring is arranged on the outer connecting plate, and a plurality of convex points are fixedly connected to the annular ring at equal intervals.

[0012] As a further improvement, a plurality of the movable pressure frames are arranged in a circular array, the movable pressure frame comprises a mounting hook welded to the inner wall of the mixing tank, a movable cylinder is provided at the end of the mounting hook, the pressure rod is slidably mounted in the movable cylinder, and the pressure rod is movably fitted on the annular ring.

[0013] As a further improvement, the side of the pressure rod facing the rotation direction of the protrusion is an inclined surface.

[0014] As a further improvement, the stirring blade includes an inner stirring part connected to a lower stirring rod, outer stirring parts are provided at both ends of the outer side of the inner stirring part, a sealing section is provided in the gap between the outer stirring part and the outer edge of the inner stirring part, and both ends of the outer stirring part are locked on the inner stirring part, and micropores with a pore size smaller than the particle size of the alloy powder are opened on the outer stirring part.

[0015] As a further improvement, the thickness of the inner stirring portion is greater than the thickness of the stirring section of the upper stirring rod.

[0016] The beneficial effects of the present invention are: In the existing cemented carbide powder mixing equipment, in order to improve the stirring of the bottom alloy powder, the output power or stirring power of the motor is generally increased. However, this method is prone to cause re-deposition and increase the wear of the output shaft. In addition, the entire stirring shaft requires a large cost to replace. Therefore, the present invention divides the entire stirring structure into an upper stirring rod and a lower stirring rod through the setting of a lower powder docking structure, thereby reducing the weight of the upper half of the entire stirring structure. Only the part of the lower half that stirs the alloy powder is thickened and separately set. During a long stirring process, even if the stirring structure is worn, only the lower half of the entire structure can be replaced, which is more cost-effective. The lower stirring rod is set in a limiting cylinder and is restricted by the limiting cylinder and will not deviate from the direction during rotation.

[0017] In the process of limiting the lower stirring rod by the limiting cylinder, it is not only limited by the inner wall of the circular cavity itself, but also an annular pad is provided on the inner wall of the circular cavity, so that the lower stirring rod is tightly confined to an area through the clamping ring and the limiting strip of the annular pad, which has a certain activity effect and can ensure that the rotation of the lower stirring rod does not appear centrifugal.

[0018] In the process of the upper stirring rod and the lower stirring rod cooperating, the two need to be movable and have a certain linkage relationship. Therefore, in the present invention, hexagonal grooves and hexagonal studs are respectively provided on the upper stirring rod and the lower stirring rod, so that the two can cooperate with each other and are not prone to slipping.

[0019] In the above, the upper stirring rod and the lower stirring rod are arranged in sections, but due to the different weights of the two and the force problems of the long and short arrangements, the matching fluctuations and even deformations are likely to occur at the limit positions of the two. Therefore, the present invention arranges an outer sleeve ring at the matching position of the upper stirring rod and the lower stirring rod, and disperses the vibrations that may occur at the matching position of the two to the entire tank body through the middle guide seat and connecting ribs, external guide seat and other structures of the outer sleeve ring, thereby improving the practicality of the present invention.

[0020] Although the stirring structure of the lower part can be replaced by a segmented arrangement, if the phenomenon of alloy powder sinking is not improved, a large amount of deposited powder will frequently contact the lower stirring rod, which will greatly shorten the life of the lower stirring rod. Therefore, the present invention arranges a lower flow-through structure on the basis of the lower powder docking structure. During the stirring process of the lower stirring rod, the annular table connected to it can be driven to move, thereby touching and lifting the pressure rod in the movable pressure frame, so that the pressure rod can agitate the entire alloy powder accumulation layer, and then let part of the alloy powder overflow, thereby reducing the pressure on the lower stirring rod at the lower end, and thus improving the overall life of the entire stirring structure.

[0021] If only the pressure brought by the stirring blades on the lower stirring rod is used to form a vortex force to drive the alloy powder to overflow, the effect will be poor, and only a small part of the alloy powder will rise. Therefore, when the lower stirring rod rotates, it will synchronously drive the annular table to rotate, so that the bumps on the annular table collide and drive the pressure rod in the movable pressure frame to do up and down piston movement, continuously pumping the alloy powder at the lower end upward, so that the alloy powder at the lower end gradually overflows, and the overflowing powder will reduce the pressure of the lower stirring rod at the lower end, forming a virtuous circle.

[0022] During the up and down displacement of the pressure rod, if it is not guided, it will no longer be able to cooperate with the protrusion after the movement. Therefore, the present invention arranges a mounting hook and a movable cylinder outside the movable track of the pressure rod. During the up and down movement of the pressure rod, the pressure rod will be completely limited by the movable cylinder, so that it can only move up and down, thereby being able to operate more stably.

[0023] When the stirring blades of the lower stirring rod are in contact with the alloy powder, they will encounter greater resistance and cause damage to themselves. In order to reduce the damage to the stirring blades themselves, the present invention divides the stirring blades into multiple sections, and divides them into an inner stirring part and an outer stirring part of an inner and outer layer. The inner stirring part only contacts the liquid, while the outer stirring part can contact the liquid and the alloy powder at the same time, so that only the outer stirring part is worn. During maintenance, the corresponding parts can be replaced more accurately, thereby improving the overall service life without affecting the mixing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the embodiments of the present invention, all belong to the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0036] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as referring to the purpose, technical solutions and advantages of the methods. To be more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work indicate or imply relative importance or implicitly indicate the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0037] Reference Figures 1 to 9 As shown, a mixing device for cemented carbide material processing comprises: a stabilizing seat 10, a mixing tank 20 arranged on the stabilizing seat 10, a stirring structure 30 is arranged on the mixing tank 20, a powder feed port and a liquid feed port are arranged on the top of the mixing tank 20, and the mixing device further comprises: a lower powder docking structure 40, the stirring structure 30 comprises a driving motor 31 and an upper stirring rod 32, the lower powder docking structure 40 comprises a limiting cylinder 41 fixed to the bottom of the mixing tank 20, a lower stirring rod 42 is movably installed on the inner side of the limiting cylinder 41, and the lower stirring rod 42 is connected to the upper The stirring rod 32 is clamped, and a stirring blade 44 is arranged on the outer side of the lower stirring rod 42. An outer sleeve ring 43 is arranged on the outer side of the lower stirring rod 42 and the upper stirring rod 32; the lower flow structure 50 includes an annular platform 51 located below the stirring blade 44, and the annular platform 51 is connected to the lower stirring rod 42 and rotates with the lower stirring rod 42. A plurality of groups of movable pressure frames 52 are arranged on the upper end of the outer edge of the annular platform 51, and a pressure rod 521 is arranged on the inner side of the movable pressure frame 52. When the annular platform 51 rotates, the pressure rods 521 in the plurality of movable pressure frames 52 are driven to lift up, thereby poking the alloy powder at the bottom upward.

[0038] During installation, the bottom cover of the mixing tank 20 is matched with the main body of the mixing tank 20, and then the stirring structure 30 and the top cover of the mixing tank 20 are locked to the main body of the mixing tank 20, so that the upper stirring rod 32 of the stirring structure 30 is connected with the lower stirring rod 42 to form a complete structure, and then the forming agent and alloy powder are fed from the powder feed port and the liquid feed port.

[0039] In the existing cemented carbide powder mixing equipment, in order to improve the stirring of the bottom alloy powder, the output power or stirring power of the motor is generally increased. However, this method is prone to cause re-deposition and increase the wear of the output shaft. In addition, the entire stirring shaft requires a large cost to replace. Therefore, in this embodiment, the lower powder docking structure 40 is set up to divide the entire stirring structure into an upper stirring rod 32 and a lower stirring rod 42, thereby reducing the weight of the upper half of the entire stirring structure. Only the part of the lower half that stirs the alloy powder is thickened and set separately. During the long-term stirring process, even if the stirring structure is worn, only the lower half of the entire structure can be replaced, which is more cost-effective. The lower stirring rod 42 is set in the limit cylinder 41 and is restricted by the limit cylinder 41. It will not deviate from the direction during rotation.

[0040] In the process of limiting the lower stirring rod 42 by the limiting cylinder 41, several parts of limiting and fixing are included. Specifically, the limiting cylinder 41 includes a circular cavity 411 for accommodating the lower stirring rod 42. A cushion seat 412 is arranged at the bottom of the circular cavity 411, and a plurality of annular pads 413 are arranged on the inner circumference of the circular cavity 411. Not only is the limiting effect achieved by the inner wall of the circular cavity 411 itself, but an annular pad 413 is also arranged on the inner wall of the circular cavity 411, so that the lower stirring rod 42 is tightly limited to an area by the clamping ring 4131 and the limiting strip 4132 of the annular pad 413, which has a certain activity effect and can ensure that the rotation of the lower stirring rod 42 does not appear centrifugal.

[0041] In particular, in the limiting fixation of the annular pad 413, it is specifically divided into two parts. The annular pad 413 includes a clamping ring 4131 that fits with the lower stirring rod 42. A limiting strip 4132 is arranged on the outer side of the clamping ring 4131. The limiting strip 4132 is fixed to the inner wall of the circular cavity 411. The clamping ring 4131 is fixed by the limiting strip 4132 and then fixed to the lower stirring rod 42, so that the turnover of the lower stirring rod 42 can be maintained.

[0042] In the process of cooperation between the upper stirring rod 32 and the lower stirring rod 42, the two need to be movably arranged and have a certain linkage relationship. Therefore, a hexagonal stud 421 is integrally formed at the bottom of the lower stirring rod 42 of the present embodiment, and a hexagonal groove 321 is provided at the upper end of the upper stirring rod 32. After the lower stirring rod 42 is installed, the hexagonal stud 421 is clamped in the hexagonal groove 321. The hexagonal groove 321 and the hexagonal stud 421 are respectively provided on the upper stirring rod 32 and the lower stirring rod 42, so that the two can cooperate with each other and are not prone to slipping.

[0043] In the above, the upper stirring rod 32 and the lower stirring rod 42 are arranged in sections, but due to the different weights of the two and the force problems of the long and short arrangements, the matching fluctuations and even deformations are likely to occur at the limit positions of the two. Therefore, the outer sleeve ring 43 of this embodiment includes a middle guide seat 431 arranged on the outside of the hexagonal groove 321, and a plurality of connecting ribs 432 are arranged on the outside of the middle guide seat 431. All of the connecting ribs 432 are installed on the external guide seat 433. By setting the outer sleeve ring 43 at the matching position of the upper stirring rod 32 and the lower stirring rod 42, and through the structures such as the middle guide seat 431, the connecting ribs 432, and the external guide seat 433 of the outer sleeve ring 43, the vibrations that may occur at the matching position of the two are dispersed to the entire tank body, thereby improving the practicality of the present invention.

[0044] Although the stirring structure of the lower part can be replaced by a segmented arrangement, if the phenomenon of alloy powder sinking is not improved, a large amount of deposited powder will frequently contact the lower stirring rod 42, which will greatly shorten the life of the lower stirring rod 42. Therefore, the present invention provides a lower flow-through structure 50 on the basis of the lower powder docking structure 40. During the stirring process of the lower stirring rod 42, the annular table 51 connected thereto can be driven to move, thereby touching and lifting the pressure rod 521 in the movable pressure frame 52, so that the pressure rod 521 can agitate the entire alloy powder accumulation layer, thereby allowing part of the alloy powder to overflow, thereby reducing the pressure on the lower stirring rod 42 at the lower end, thereby improving the overall life of the entire stirring structure.

[0045] If only the pressure brought by the stirring blades 44 on the lower stirring rod 42 is used to form a vortex force to drive the alloy powder to overflow, the effect is poor, and only a small part of the alloy powder will rise. Therefore, the annular table 51 of this embodiment includes an external connecting plate 511 fixed to the outside of the lower stirring rod 42, and an annular ring 512 is provided on the external connecting plate 511. The annular ring 512 is fixedly connected with a plurality of protrusions 513 at equal intervals. When the lower stirring rod 42 rotates, it will synchronously drive the annular table 51 to rotate, so that the protrusions 513 on the annular table 51 collide and drive the pressure rod 521 in the movable pressure frame 52 to perform up and down piston movement, continuously pumping the alloy powder at the lower end upward, so that the alloy powder at the lower end gradually overflows, and the overflowing powder will reduce the pressure of the lower stirring rod 42 at the lower end, forming a virtuous cycle.

[0046] During the up and down displacement of the pressure rod 521, if it is not guided, it will no longer be able to cooperate with the protrusion 513 after the movement. Therefore, the plurality of movable pressure frames 52 of this embodiment are arranged in a ring array, and the movable pressure frame 52 includes a mounting hook 522 welded to the inner wall of the mixing tank 20, and a movable cylinder 523 is provided at the end of the mounting hook 522. The pressure rod 521 is slidably installed in the movable cylinder 523, and the pressure rod 521 is movably fitted on the annular ring 512. By arranging the mounting hook 522 and the movable cylinder 523 outside the movable track of the pressure rod 521, the pressure rod 521 will be completely limited by the movable cylinder 523 during the up and down movement, so that it can only move up and down, thereby being able to operate more stably.

[0047] In order to make the pressure rod 521 cooperate better with the protrusion 513 and prevent the protrusion 513 from getting stuck, the side of the pressure rod 521 in the present embodiment facing the rotation direction of the protrusion 513 is an inclined surface, so that it can be lifted up during the rapid rotation of the protrusion 513.

[0048] When the stirring blade 44 of the lower stirring rod 42 contacts with the alloy powder, it will encounter greater resistance and cause damage to itself. In order to reduce the damage to the stirring blade 44 itself, the stirring blade 44 of this embodiment includes an inner stirring part 441 connected to the lower stirring rod 42, and both ends of the outer side of the inner stirring part 441 are provided with outer stirring parts 442. The gap between the outer stirring part 442 and the outer edge of the inner stirring part 441 is provided with a sealing section 443, and both ends of the outer stirring part 442 are locked on the inner stirring part 441. The outer stirring part 442 is provided with micropores with an aperture smaller than the particle size of the alloy powder. By dividing the stirring blade 44 into multiple sections, it is divided into an inner and outer layer of an inner stirring part 441 and an outer stirring part 442. The inner stirring part 441 is only in contact with the liquid, while the outer stirring part 442 can be in contact with the liquid and the alloy powder at the same time, so that only the outer stirring part 442 is worn. During maintenance, the corresponding parts can be replaced more accurately, thereby improving the overall service life without affecting the mixing effect.

[0049] The thickness of the inner stirring portion 441 is greater than the thickness of the stirring section of the upper stirring rod 32 .

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
