Description

Technical Field

[0001] The present invention relates to a processing device for cemented carbide materials, in particular to a mixing device for processing cemented carbide materials. Background Art

[0002] In the forming process of cemented carbide rods, raw materials such as tungsten carbide (WC) and cobalt (Co) are added and mixed in proportion, refined by a ball mill to ensure the uniformity of the powder, and the refined cemented carbide material is mixed with a forming agent. Subsequently, the water is removed by drying, and the material after water removal is pressed into shape and sintered at high temperature. The sintered workpiece is ground and polished and then can be stored in the warehouse.

[0003] When traditional equipment mixes materials, alloy powder and a forming agent are usually added to a stirring tank for stirring. However, with this stirring method, since the mass of the alloy powder is often greater than that of the solution and the forming agent, some alloy powder will sink to the bottom. Therefore, in the prior art, the strength of the stirring blades is enhanced and the output strength of the motor is increased to push the powder deposited at the bottom upwards. Even more, a gas ejection structure is provided at the bottom of the mixing equipment to stir the alloy powder with gas. However, in fact, the weight of the alloy powder is relatively heavy, especially at the bottom where there is a large amount of deposition. It is often difficult to guide the powder at the bottom upwards with gas. Moreover, some agglomerated powder not only easily hinders stirring, causing a large pressure on the stirring rods in the lower half, but also easily accumulates the temperature rise phenomenon caused by stirring the powder in the lower half position, which is likely to affect the chemical composition of the powder, resulting in a non-compliance of a certain characteristic of the formed workpiece.

[0004] Therefore, this case aims to provide a mixing device for processing cemented carbide materials, which can provide sufficient stirring strength in the lower half of the equipment, and at the same time can play a certain agitating effect on the powder during stirring, allowing more bottom powder to be added to the stirring areas in the middle and upper parts, improving the mixing effect and ensuring the uniformity of the mixing temperature. Summary of the Invention

[0005] The present invention provides a mixing device for processing cemented carbide materials, which can effectively solve the above problems.

[0006] The present invention is implemented as follows:

[0007] A mixing device for processing cemented carbide materials includes: a stable base, a mixing tank disposed on the stable base, a stirring structure disposed on the mixing tank, a powder inlet and a liquid inlet disposed at the top of the mixing tank. The mixing equipment further includes:

[0008] Lower powder docking structure. The stirring structure includes a driving motor and an upper stirring rod. The lower powder docking structure includes a limiting cylinder fixed to the inner bottom of the mixing tank. A lower stirring rod is movably installed inside the limiting cylinder. The lower stirring rod is clamped with the upper stirring rod. Stirring blades are arranged on the outer side of the lower stirring rod. An outer sleeve ring is arranged on the outer sides of the lower stirring rod and the upper stirring rod.

[0009] Underflow structure, including an annular platform located below the stirring blades. The annular platform is connected to the lower stirring rod and rotates with the lower stirring rod. Several groups of movable pressing frames are arranged at the upper end of the outer edge of the annular platform. A pressing rod is arranged inside the movable pressing frame. When the annular platform rotates, the pressing rods in several movable pressing frames are lifted upward, so as to poke the alloy powder at the bottom upward.

[0010] As a further improvement, the limiting cylinder includes a circular cavity cylinder for accommodating the lower stirring rod. A cushion seat is arranged at the bottom of the circular cavity cylinder. Several annular gaskets are arranged on the inner peripheral surface of the circular cavity cylinder.

[0011] As a further improvement, the annular gasket includes a clamping ring that fits the lower stirring rod. A limiting strip is arranged on the outer side of the clamping ring. The limiting strip is fixedly connected to the inner side wall of the circular cavity cylinder.

[0012] As a further improvement, an internal hexagonal stud is integrally formed at the top of the lower stirring rod. An internal hexagonal groove is opened at the lower end of the upper stirring rod. After the lower stirring rod is installed, the internal hexagonal stud is clamped in the internal hexagonal groove.

[0013] As a further improvement, the outer sleeve ring includes a middle guide seat sleeved outside the internal hexagonal groove. Several connecting ribs are arranged on the outer side of the middle guide seat. All the connecting ribs are installed on the outer guide seat.

[0014] As a further improvement, the annular platform includes an outer connecting disc fixed to the outer side of the lower stirring rod. A circular ring is arranged on the outer connecting disc. Several convex points are equidistantly and fixedly connected to the circular ring.

[0015] As a further improvement, several of the movable pressing frames are arranged in a circular array. The movable pressing frame includes a mounting hook welded to the inner side wall of the mixing tank. There is a movable cylinder at the end of the mounting hook. The pressing rod is slidably installed in the movable cylinder. The pressing rod is movably attached to the circular ring.

[0016] As a further improvement, the side of the pressing rod facing the rotation direction of the convex point is an inclined surface.

[0017] As a further improvement, the stirring blade includes an inner stirring part connected to the lower stirring rod. Outer stirring parts are arranged at both ends on the outer side of the inner stirring part. A sealing section is arranged in the gap between the outer stirring part and the outer edge of the inner stirring part. The head and tail ends of the outer stirring part are locked on the inner stirring part, and micropores with pore diameters smaller than the particle diameter of the alloy powder are formed on the outer stirring part.

[0018] As a further improvement, the thickness of the inner stirring part is greater than the thickness of the stirring section of the upper stirring rod.

[0019] The beneficial effects of the present invention are as follows:

[0020] In the existing mixing equipment for cemented carbide powder, in order to improve the stirring of the bottom alloy powder, generally the output power of the motor or the stirring power is increased. However, using this method is likely to cause re-deposition while increasing the wear of the output shaft, and the entire stirring shaft requires a large cost when being replaced. Therefore, through the lower powder docking structure provided in the present invention, the entire stirring structure is divided into an upper stirring rod and a lower stirring rod, so as to reduce the weight of the upper half of the entire stirring structure. Only the part for stirring the alloy powder in the lower half 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 needs to be replaced, which is more cost-saving. Moreover, the lower stirring rod is arranged in the limiting cylinder and is restricted by the limiting cylinder, so it will not deviate from the direction during the rotation process.

[0021] During the process of the limiting cylinder limiting the lower stirring rod, it not only limits through the inner wall of the circular cavity cylinder itself, but also an annular pad is arranged on the inner wall of the circular cavity cylinder. Thus, the lower stirring rod is tightly restricted in a region through the clamping ring and the limiting strip of the annular pad, having a certain activity effect while ensuring that the rotation of the lower stirring rod does not show a centrifugal phenomenon.

[0022] During the cooperation process of the upper stirring rod and the lower stirring rod, the two need to be set to be movable and also have a certain linkage relationship. Therefore, in the present invention, inner hexagonal grooves and inner hexagonal studs are respectively arranged 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.

[0023] In the above, the upper stirring rod and the lower stirring rod are arranged in sections. However, due to the different weights of the two and the force problem of the far and near settings, the cooperation position between the two is prone to cooperation fluctuations or even deformation. Therefore, in the present invention, an outer sleeve ring is arranged at the cooperation position of the upper stirring rod and the lower stirring rod. Through the middle guide seat, connecting ribs, outer guide seats and other structures of the outer sleeve ring, the vibration that may occur at the cooperation position between the two is dispersed to the entire tank body, thereby improving the practicability of the present invention.

[0024] Although the stirring structure in the lower part is made replaceable by means of segmented setting, if the phenomenon of alloy powder sinking is not improved, the powder deposited in large quantities will frequently contact the lower stirring rod, greatly shortening the service life of the lower stirring rod. Therefore, in the present invention, a downward through-flow structure is provided on the basis of the lower powder docking structure. During the stirring process of the lower stirring rod, it can drive the action of the annular platform connected thereto, thereby touching the pressure rod in the lifting movable pressure-applying frame, enabling the pressure rod to agitate the entire alloy powder accumulation layer, and further causing some alloy powder to overflow, thereby reducing the pressure on the lower stirring rod at the lower end, and further improving the overall service life of the entire stirring structure.

[0025] If only the pressure driven 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 is poor, and only a very small part of the alloy powder will rise. Therefore, when the lower stirring rod rotates, it will synchronously drive the annular platform to rotate, so that the bumps on the annular platform collide to drive the pressure rod in the movable pressure-applying frame to perform up-and-down piston motion, continuously pumping the alloy powder at the lower end upward, so that the alloy powder at the lower end gradually overflows. The powder after overflow will reduce the pressure on the lower stirring rod at the lower end, forming a virtuous cycle.

[0026] During the up-and-down displacement process of the pressure rod, if it is not guided, it will not be able to cooperate with the bumps after movement. Therefore, in the present invention, mounting hooks and movable cylinders are provided on the outer side of the movement track of the pressure rod. The pressure rod will be completely limited by the movable cylinder during the up-and-down movement process, so that it can only move up and down, and thus can operate more stably.

[0027] During the contact process between the stirring blades of the lower stirring rod and the alloy powder, it will be subject to a large resistance and cause damage to itself. In order to reduce the damage to the stirring blades themselves, the present invention divides the stirring blades into multiple segments, dividing them into an inner stirring part and an outer stirring part of the inner and outer layers. The inner stirring part only contacts the liquid, while the outer stirring part can contact both the liquid and the alloy powder. Therefore, only the outer stirring part is subject to wear, and the corresponding part can be replaced more accurately during maintenance, thereby improving the overall service life without affecting the mixing effect.

Therefore, the following detailed description of the implementation manners of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents the selected implementation manners of the present invention. All other implementation manners obtained by those of ordinary skill in the art based on the implementation manners in the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0041] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined. To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of the present invention.

[0042] Referring to Figures 1 to 9 As shown, a mixing device for processing cemented carbide materials includes: a stable base 10, a mixing tank 20 disposed on the stable base 10, a stirring structure 30 disposed on the mixing tank 20, a powder inlet and a liquid inlet disposed at the top of the mixing tank 20. The mixing device further includes: a lower powder docking structure 40, the stirring structure 30 includes a driving motor 31 and an upper stirring rod 32, the lower powder docking structure 40 includes a limiting cylinder 41 fixed to the inner bottom of the mixing tank 20, a lower stirring rod 42 is movably installed inside the limiting cylinder 41, the lower stirring rod 42 is clamped with the upper stirring rod 32, stirring blades 44 are disposed on the outer side of the lower stirring rod 42, and an outer sleeve ring 43 is disposed on the outer sides of the lower stirring rod 42 and the upper stirring rod 32; a downward flow-through structure 50, including an annular platform 51 located below the stirring blades 44, the annular platform 51 is connected to the lower stirring rod 42 and rotates with the lower stirring rod 42, several groups of movable pressing frames 52 are disposed at the upper end of the outer edge of the annular platform 51, a pressing rod 521 is disposed inside the movable pressing frame 52, and when the annular platform 51 rotates, the pressing rod 521 in several movable pressing frames 52 is lifted upward, so as to poke the alloy powder at the bottom upward.

[0043] During installation, the bottom cover of the mixing tank 20 is fitted 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 docked with the lower stirring rod 42 to form a complete structure, and then the forming agent and the alloy powder are fed through the powder inlet and the liquid inlet.

[0044] In existing mixing equipment for cemented carbide powder, in order to improve the stirring of the bottom alloy powder, generally the output power of the motor or the stirring power will be increased. However, using this method is likely to cause re-deposition while increasing the wear of the output shaft, and the entire stirring shaft requires a relatively high cost to replace. Therefore, in this embodiment, by providing the lower powder docking structure 40, the entire stirring structure is divided into the upper stirring rod 32 and the lower stirring rod 42, so as to reduce the weight of the upper half of the entire stirring structure. Only the part for stirring the alloy powder in the lower half is thickened and separately provided. During the long-term stirring process, even if the stirring structure is worn, only the lower part of the entire structure needs to be replaced, which is more cost-saving. Moreover, the lower stirring rod 42 is arranged in the limiting cylinder 41 and is restricted by the limiting cylinder 41, so it will not deviate from the direction during rotation.

[0045] During the process of the limiting cylinder 41 limiting the lower stirring rod 42, it includes several parts of limiting and fixing. Specifically, the limiting cylinder 41 includes a circular cavity 411 for accommodating the lower stirring rod 42. A cushion seat 412 is provided at the bottom of the circular cavity 411. A plurality of annular gaskets 413 are provided on the inner peripheral surface of the circular cavity 411. It is not only limited by the inner wall of the circular cavity 411 itself, but also an annular gasket 413 is provided on the inner wall of the circular cavity 411. Thus, through the clamping ring 4131 and the limiting strip 4132 of the annular gasket 413, the lower stirring rod 42 is tightly restricted in a region, having a certain degree of mobility while ensuring that the rotation of the lower stirring rod 42 does not show a centrifugal phenomenon.

[0046] Especially in the limiting and fixing of the annular gasket 413, it is specifically divided into two parts. The annular gasket 413 includes a clamping ring 4131 that fits with the lower stirring rod 42. A limiting strip 4132 is provided on the outer side of the clamping ring 4131. The limiting strip 4132 is fixedly connected to the inner side wall of the circular cavity 411. By fixing the clamping ring 4131 through the limiting strip 4132 and then fixing it to the lower stirring rod 42, the turnover degree of the lower stirring rod 42 can be maintained.

[0047] During the cooperation process of the upper stirring rod 32 and the lower stirring rod 42, they need to be movably arranged and have a certain linkage relationship. Therefore, in this embodiment, an internal hexagonal stud 421 is integrally formed at the top of the lower stirring rod 42, and an internal hexagonal groove 321 is opened at the lower end of the upper stirring rod 32. After the lower stirring rod 42 is installed, the internal hexagonal stud 421 is clamped in the internal hexagonal groove 321. The internal hexagonal groove 321 and the internal hexagonal stud 421 are respectively provided on the upper stirring rod 32 and the lower stirring rod 42, enabling them to cooperate with each other and not easily slip.

[0048] In the above, the upper stirring rod 32 and the lower stirring rod 42 are arranged in sections. However, due to the different weights of the two and the force-bearing problems caused by their different distances, there are prone to cooperation fluctuations or even deformation at their limiting positions. Therefore, the outer sleeve ring 43 in this embodiment includes a middle guide seat 431 sleeved outside the inner hexagonal groove 321. A plurality of connecting ribs 432 are arranged on the outside of the middle guide seat 431, and all the connecting ribs 432 are installed on the outer guide seat 433. By arranging the outer sleeve ring 43 at the matching position of the upper stirring rod 32 and the lower stirring rod 42, through the middle guide seat 431, connecting ribs 432, outer guide seat 433 and other structures of the outer sleeve ring 43, the vibration that may occur at their matching position is dispersed to the entire tank body, thereby improving the practicability of the present invention.

[0049] Although the purpose of making the stirring structure in the lower half part replaceable is achieved by the method of sectional arrangement, if the phenomenon of alloy powder sinking is not improved, the powder deposited in large amounts frequently contacts the lower stirring rod 42, which will greatly shorten the service life of the lower stirring rod 42. Therefore, a downward through-flow structure 50 is provided on the basis of the lower powder docking structure 40 in the present invention. During the stirring process of the lower stirring rod 42, it can drive the annular platform 51 connected thereto to move, thereby touching the pressure rod 521 in the lifting movable pressure-applying frame 52, enabling the pressure rod 521 to agitate the entire alloy powder accumulation layer, and then causing some alloy powder to overflow, thereby reducing the pressure on the lower stirring rod 42 at the lower end, and further improving the overall service life of the entire stirring structure.

[0050] If only the pressure driven 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 very small part of the alloy powder will rise. Therefore, the annular platform 51 in this embodiment includes an outer connection disk 511 fixed outside the lower stirring rod 42. An annular ring 512 is arranged on the outer connection disk 511, and a plurality of convex points 513 are fixedly connected to the annular ring 512 at equal intervals. When the lower stirring rod 42 rotates, it will drive the annular platform 51 to rotate synchronously, so that the convex points 513 on the annular platform 51 collide to drive the pressure rod 521 in the movable pressure-applying frame 52 to perform an up-and-down piston motion, continuously pumping the alloy powder at the lower end upwards, so that the alloy powder at the lower end gradually overflows. The powder after overflow will reduce the pressure on the lower stirring rod 42 at the lower end, forming a virtuous cycle.

[0051] During the up-and-down displacement of the pressure application rod 521, if it is not guided, it cannot cooperate with the bump 513 after movement. Therefore, a plurality of the movable pressure application frames 52 in this embodiment are arranged in a circular array. The movable pressure application frame 52 includes a mounting hook 522 welded to the inner side wall of the mixing tank 20. There is a movable cylinder 523 at the end of the mounting hook 522. The pressure application rod 521 is slidably installed in the movable cylinder 523. The pressure application rod 521 is movably attached to the annular ring 512. By arranging the mounting hook 522 and the movable cylinder 523 outside the movement track of the pressure application rod 521, the pressure application 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, and thus can operate more stably.

[0052] In order to enable the pressure application rod 521 to better cooperate with the bump 513 and avoid the bump 513 from getting stuck, one side of the pressure application rod 521 in this embodiment facing the rotation direction of the bump 513 is an inclined surface, so that it can be lifted during the rapid rotation of the bump 513.

[0053] During the process of the stirring blade 44 of the lower stirring rod 42 contacting the alloy powder, it will be subjected to a large resistance and cause damage to itself. In order to reduce the damage to the stirring blade 44 itself, the stirring blade 44 in this embodiment includes an inner stirring part 441 connected to the lower stirring rod 42. Outer stirring parts 442 are arranged at both ends of the outer side of the inner stirring part 441. A sealing section 443 is arranged in the gap between the outer stirring part 442 and the outer edge of the inner stirring part 441. The head and tail ends of the outer stirring part 442 are locked to the inner stirring part 441. Micropores with apertures smaller than the particle size of the alloy powder are provided on the outer stirring part 442. By dividing the stirring blade 44 into multiple sections and dividing it into the inner stirring part 441 and the outer stirring part 442 of the inner and outer layers, the inner stirring part 441 only contacts the liquid, while the outer stirring part 442 can contact both the liquid and the alloy powder. Therefore, only the outer stirring part 442 is worn. During maintenance, the corresponding parts can be replaced more precisely, so as to improve the overall service life without affecting the mixing effect.

[0054] Among them, the thickness of the inner stirring part 441 is greater than the thickness of the stirring section of the upper stirring rod 32.

[0055] The above is only the preferred implementation manner of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
