Description

Technical Field

[0001] This utility model relates to the field of powder processing and molding technology, and more specifically, to a powder forming device for forming powder materials. Background Technology

[0002] Traditional metal powder metallurgy is a process that uses various metal powders as raw materials, and manufactures finished products and metal materials through pressing, sintering, and necessary post-processing. In the 1930s, metal powder metallurgy successfully manufactured porous oil-impregnated bearings. With the use of inexpensive iron powder, powder metallurgy began to be applied on a large scale in industries such as automobiles and textiles. However, existing equipment on the market currently has several problems in the production process: the seals in the feed cylinder are prone to wear, and impurities from the wear can easily mix with the raw materials, leading to defects in the finished products; production efficiency is low; the equipment has a short service life; and there is no automatic feeding device, so production can only be completed manually, which cannot meet the needs of continuous production.

[0003] Existing technologies have proposed improved structural forms to address the problems of low productivity and short equipment lifespan. Patent application number 201921861467.X, entitled "Powder Material Extrusion Molding Equipment," provides a powder material extrusion molding equipment. This equipment uses a tilting cylinder to vertically raise the material cylinder, allowing manual placement of the mixed powder material into the cylinder's internal cavity before extrusion molding. While this improves efficiency to some extent and automates some processes, in practical engineering, the vertical operation of the extrusion cylinder on the frame, due to the structural limitations of the frame in the vertical direction, cannot meet the demands of high-pressure extrusion molding. Furthermore, the particle size, shape, and frictional characteristics of the powder necessitate manual intervention during feeding, preventing fully automated deployment and thus impacting the efficiency of powder molding production.

[0004] In view of this, there is an urgent need for a powder forming device that is not affected by the inherent characteristics of powder particle size, shape, and friction, requires no manual intervention, can effectively avoid the clogging problem that easily occurs when powder enters the mold cavity, can provide greater forming pressure, and can automatically complete the entire process of powder feeding and extrusion, greatly improving production speed and efficiency, reducing labor input, and having a simple structure, convenient operation, strong practicality, and easy promotion and use. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a powder forming device that is not affected by the inherent characteristics of powder particle size, shape, and friction, requires no manual intervention, effectively avoids the clogging problem that easily occurs when powder enters the mold cavity, can provide greater forming pressure, and the entire process of powder feeding and extrusion is completed automatically, greatly improving production speed and efficiency, reducing labor input, and having a simple structure, convenient operation, strong practicality, and easy promotion and use.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0007] A powder forming device includes a frame, a first telescopic part, a second telescopic part, a forming part, and an inlet hopper. The forming part is embedded and fixed within the frame. The first telescopic part extends horizontally through the frame and into the internal cavity of the forming part, and is configured to expand and contract with respect to the volume of the forming cavity. The inlet hopper is located at the top of the forming part and is in a cut-off communication with it. The second telescopic part is located between the forming part and the inlet hopper and is drivably connected into the inlet hopper. Thus, powdered material, after being precisely metered in the cut-off communication between the inlet hopper and the forming part, enters the forming part. The first telescopic part, positioned horizontally, provides greater molding pressure to change the volume of the cavity inside the molding part, thereby compressing the powder and finally processing it into parts. Furthermore, driven by the second telescopic part, it ensures that the material in the inlet hopper is not affected by the inherent characteristics of the powder's particle size, shape, and friction. Without manual intervention, it effectively avoids the clogging problem that easily occurs when the powder enters the cavity. The entire process of powder feeding and extrusion is completed automatically, greatly improving production speed and efficiency, reducing labor input, and featuring a simple structure, convenient operation, strong practicality, and ease of promotion and use.

[0008] Furthermore, it also includes a fixing part disposed between the molding part and the first telescopic part, wherein the first telescopic part extends into the internal cavity of the molding part after passing through the fixing part, and is configured to be compressible and expandable with respect to the internal molding cavity of the molding part.

[0009] Furthermore, the fixing part includes a first mounting plate, a second mounting plate, and at least two connecting rods, wherein the first mounting plate and the second mounting plate are arranged at intervals and parallel to each other, and the connecting rods are arranged between the first mounting plate and the second mounting plate at intervals.

[0012] Furthermore, it also includes a coupling and a rotary shaft disposed between the second telescopic cylinder and the agitator plate, wherein one end of the rotary shaft is rotatably connected to the second telescopic cylinder via the coupling, and the other end disposed opposite to it is fixed to the agitator plate and is configured to move together.

[0013] Furthermore, the molding part includes a molding cavity and an extrusion plate that is spaced apart from the molding cavity by an extrusion rod, wherein one end of the extrusion rod is connected to the extrusion plate; the other end of the extrusion rod is disposed opposite to the extrusion plate and penetrates the internal cavity of the molding cavity, and is compressibly arranged to extend and retract relative to the molding cavity.

[0014] Furthermore, the molding cavity includes a cavity body, an extrusion cavity, and a connecting plate, wherein the cavity body is fixed to the frame via the connecting plate; the extrusion cavity is formed on the cavity body and extends along the length of the cavity body.

[0015] Furthermore, the inlet hopper includes a mounting flange, a guide trough, and a mounting block. The guide trough is a channel formed by welding a panel and a support rib, and has an overall funnel shape. The mounting flange is located at the top of the guide trough, and one end of the mounting block is connected to the bottom end of the guide trough, while the other end of the block extends toward the forming part.

[0016] Furthermore, it also includes a third telescopic section disposed on the top of the frame, located between the frame and the first telescopic section.

[0017] The powder forming device provided in the above embodiments, through the connecting rod set between the first mounting plate and the second mounting plate, leaves a certain working space between the first telescopic part and the forming part, which facilitates the installation and maintenance of the telescopic part of the first telescopic part; the movable part of the first telescopic cylinder compresses the powder inside the forming part in a very convenient manner along the horizontal direction, with good mechanical properties and can provide sufficient compression force to meet the extrusion molding under high pressure; the coupling and rotary shaft set between the second telescopic cylinder and the stirring plate can compensate for the offset (including axial offset, radial offset, angular offset or combined offset) caused by inaccurate manufacturing and installation, deformation or thermal expansion during operation, as well as the impact during the transmission process; under the action of the rotary shaft, the linear motion of the telescopic cylinder is converted into the rotary motion, which in turn drives the stirring plate to rotate in the inlet hopper, thereby improving the stirring effect on the powder in the inlet hopper; through the stirring plate fixed inside the inlet hopper, Driven by the second telescopic cylinder, the moving end of the cylinder moves inside the inlet hopper, thus stirring the powder in the hopper. This prevents the powder from being affected by its particle size, shape, or inherent frictional characteristics, effectively avoiding clogging problems that easily occur when the powder enters the mold cavity without manual intervention. This ensures that the entire process of powder feeding and extrusion can be completed smoothly and automatically, greatly improving production speed and efficiency while reducing labor input. The second dustproof ring, which is fitted onto the extrusion rod and located at the connection between the extrusion rod and the molding cavity, effectively reduces the risk of powder leakage during operation, ensuring consistency in the powder molding process.

[0026] like Figure 1As shown in the illustration, a powder forming apparatus according to a partially exemplary embodiment includes a frame 50, a first telescopic part 20, a second telescopic part 30, a forming part 40, and an inlet hopper 70. The forming part 40 is fixedly embedded inside the frame 50. The first telescopic part 20 extends horizontally through the frame 50 and into the internal cavity of the forming part 40, and is configured to be compressibly and expandably connected to the internal forming cavity of the forming part 40. The inlet hopper 70 is located at the top of the forming part 40 and is in a cut-off communication with it. The second telescopic part 30 is located between the forming part 40 and the inlet hopper 70 and is drivably connected into the inlet hopper 70. Thus, powdered material is directly cut into the inlet hopper 70 and the forming part 40. After precise measurement, the powder enters the forming section 40. Under the action of the first telescopic section 20 set in the horizontal direction, a large forming pressure is provided to change the volume of the cavity inside the forming section 40, thereby compressing the powder and finally processing it into parts. Furthermore, driven by the second telescopic section 30, it can ensure that the material in the inlet hopper 70 is not affected by the inherent characteristics of the powder particle size, shape, and friction. Without manual intervention, it can effectively avoid the clogging problem that easily occurs when the powder enters the cavity. The entire process of powder feeding and extrusion is completed automatically, which greatly improves the production speed and efficiency, reduces labor input, and has a simple structure, is easy to operate, and is highly practical and easy to promote and use.

[0027] In this embodiment, to improve the reliability of the compression operation and enhance the convenience of installation and maintenance of the compression system, a fixing part 10 is further included, disposed between the forming part 40 and the first telescopic part 20. The first telescopic part 20 passes through the fixing part 10 and extends into the internal cavity of the forming part 40, and is configured to expand and contract with the volume of the internal forming cavity of the forming part 40. Specifically, the fixing part 10 includes a first mounting plate 11, a second mounting plate 12, and at least two connecting rods 13. The first mounting plate 11 and the second mounting plate 12 are spaced apart and parallel, and the connecting rods 13 are disposed between the first mounting plate 11 and the second mounting plate 12, spaced apart. Thus, by using the connecting rods 13 disposed between the first mounting plate 11 and the second mounting plate 12, a certain amount of working space is provided between the first telescopic part 20 and the forming part 40, facilitating the installation and maintenance of the telescopic portion of the first telescopic part 20.

[0028] In this embodiment of the application, the first telescopic portion 20 can be of various suitable structures, preferably, such as Figure 2As shown, the first telescopic part 20 includes a top block 22 fixed to the movable end of the first telescopic cylinder 21 and moving together with the movable end of the first telescopic cylinder 21. Driven by the first telescopic cylinder 21, the top block 22 extends and retracts, thereby changing the volume of the internal cavity of the molding part 40 and compressing the powder inside the molding part 40. Preferably, the fixed end of the first telescopic cylinder 21 is connected to the fixed part 10, and the movable end of the first telescopic cylinder 21 extends horizontally through the fixed part 10 and then extends towards the molding part 40. Preferably, to avoid powder loss due to assembly gaps or other reasons during the compression of powder by the top block 22, a sealing ring 23 is also provided on the top block 22. This sealing ring 23 is located on the movable end of the first telescopic cylinder 21, away from the fixed end of the first telescopic cylinder 21. Furthermore, in order to ensure the consistency of the finished powder product and avoid errors caused by the loosening of the top block 22 under high pressure, an anti-loosening nut 24 is also provided against the end side of the top block 22. The anti-loosening nut 24 is located on the end side of the top block 22 near the fixed end of the first telescopic cylinder 21.

[0029] In summary, the first telescopic part provided by this utility model, through the connecting rod set between the first mounting plate and the second mounting plate, leaves a certain working space between the first telescopic part and the forming part, which facilitates the installation and maintenance of the telescopic part of the first telescopic part; through the movable part of the first telescopic cylinder along the horizontal direction, it can compress the powder inside the forming part very conveniently, with good mechanical properties and can provide a large enough compression force to meet the extrusion molding under high pressure.

[0030] In the preferred embodiment of this application, such as Figure 1 and Figure 3 As shown, to optimize the overall footprint of the powder forming device, the second telescopic part 30 is fixed to the top surface of the frame 50 and is arranged perpendicularly to the first telescopic part 20. Specifically, it includes a second telescopic cylinder 31 and a stirring plate 32. The fixed end of the second telescopic cylinder 31 is connected to the frame 50, and the stirring plate 32 is disposed inside the inlet hopper 70 and is fixed integrally with the movable end of the second telescopic cylinder 31 extending into the inlet hopper 70, and they move together. Thus, by means of the stirring plate 32 fixed inside the inlet hopper 70, driven by the second telescopic cylinder 31, it can move inside the inlet hopper 70 with the movable end of the second telescopic cylinder 31, thereby agitating the powder in the inlet hopper 70. This prevents the powder from being affected by the inherent characteristics of particle size, shape, and friction, and effectively avoids the clogging problem that easily occurs when the powder enters the mold cavity without manual intervention. This ensures that the entire process of powder feeding and extrusion can be completed smoothly and automatically, greatly improving production speed and efficiency, and reducing labor input.

[0031] Optionally, to improve the mixing effect of the powder, a coupling 33 and a rotating shaft 34 are also included between the second telescopic cylinder 31 and the stirring plate 32. One end of the rotating shaft 34 is rotatably connected to the second telescopic cylinder 31 via the coupling 33, and the other end is fixed to the stirring plate 32 and moves together with it. Specifically, one end of the coupling 33 is connected to the movable end of the second telescopic cylinder 31, and the other end is drivably connected to the rotating shaft 34.

[0032] Optionally, to ensure the continuity and reliability of the transmission, a spacer 35 is also included at the connection between the coupling 33 and the rotary shaft 34. Preferably, a first dustproof ring 36 is also included on the end side of the spacer 35. The first dustproof ring 36 is coaxial with the rotary shaft 34 and is located on the far end of the first dustproof ring 36 away from the second telescopic cylinder 31.

[0033] In summary, the second telescopic part provided by this utility model, through the coupling and rotary shaft set between the second telescopic cylinder and the stirring plate, can compensate for offsets (including axial offset, radial offset, angular offset, or combined offset) caused by inaccurate manufacturing and installation, deformation during operation, or thermal expansion, as well as impacts during transmission. Under the action of the rotary shaft, the linear motion of the first telescopic cylinder is converted into a rotary motion, which in turn drives the stirring plate to rotate in the inlet hopper, thereby improving the stirring effect on the powder in the inlet hopper. Through the stirring plate fixed inside the inlet hopper, driven by the second telescopic cylinder, it can move inside the inlet hopper with the moving end of the second telescopic cylinder, thereby realizing the stirring of the powder in the inlet hopper. This makes the powder unaffected by the inherent characteristics of powder particle size, shape, and friction, and effectively avoids the clogging problem that easily occurs when the powder enters the cavity without manual intervention. It ensures that the entire process of powder feeding and extrusion can be completed smoothly and automatically, greatly improving production speed, increasing production efficiency, and reducing labor input.

[0034] In the preferred embodiment of this application, such as Figure 1 and Figure 4 As shown, the forming section 40 includes a forming cavity 41 and an extrusion plate 42 spaced apart from the forming cavity 41 by an extrusion rod 43. One end of the extrusion rod 43 abuts against the extrusion plate 42; the other end, which is opposite to it, penetrates the internal cavity of the forming cavity 41 and is compressibly extendable relative to the forming cavity 41. Thus, the extrusion plate, through the extrusion rod, can compress the internal cavity of the forming cavity, thereby compressing the powder in the forming cavity. Combined with the first telescopic part, this achieves bidirectional extrusion of the powder in the internal cavity of the forming cavity, thereby providing sufficient extrusion pressure to form the powder.

[0035] Optionally, the molding cavity 41 includes a cavity body 411, an extrusion cavity 412, and a connecting plate 413. The cavity body 411 is fixed to the frame 50 via the connecting plate 413. The extrusion cavity 412 is formed on the cavity body 411 and extends along the length of the cavity body 411. Specifically, the extrusion cavity 412 is an upward-opening groove. Preferably, the connecting plate 413 is detachably connected to the frame 50 via a threaded post 414, which penetrates the connecting plate 413 and extends along the length of the cavity body 411.

[0036] Optionally, to avoid the risk of powder leakage during operation due to the extrusion rod 43 penetrating and extending into the internal cavity of the molding cavity 41, a second dustproof ring 44 is included, which is sleeved on the extrusion rod 43 and disposed on the outer peripheral surface of the connection between the extrusion rod 43 and the molding cavity 41. Further, to ensure the stability and reliability of the connection, a washer 45 and a sealing ring 46 are included, which are sleeved on the extrusion rod 43 and disposed between the extrusion plate 42 and the second dustproof ring 44. The sealing ring 46 fixes the second dustproof ring 44 to the outer peripheral surface of the connection between the extrusion rod 43 and the molding cavity 41 through the washer 45. Further, to ensure the safety of the extrusion rod 43 during operation, a protective cover 47 is included, which is sleeved on the extrusion rod 43 and fixedly connected to the frame 50. Preferably, the protective cover 47 is coaxially arranged with the extrusion rod 43.

[0037] In summary, the forming part provided by this utility model, by ringing around the extrusion rod and setting a second dustproof ring at the connection between the extrusion rod and the forming cavity, can effectively reduce the risk of powder leakage during the operation of the extrusion rod and ensure the consistency of the powder forming process; the extrusion plate can compress the internal cavity of the forming cavity through the extrusion rod, thereby compressing the powder in the forming cavity, and then, together with the first telescopic part, realizes bidirectional extrusion of the powder in the internal cavity of the forming cavity, thereby providing a sufficiently large extrusion pressure to achieve powder forming.

[0038] In the preferred embodiment of this application, such as Figure 1 As shown, to provide stable and smooth extrusion pressure to the forming section, at least one third telescopic cylinder 60 is also included, fixed to the frame 50 and drivenly connected to the extrusion plate 42. Specifically, the fixed end of the third telescopic cylinder 60 is embedded and fixed inside the frame 50, and the movable end of the third telescopic cylinder 60 is integrally connected to the extrusion plate 42 and moves together with it. Optionally, there are two third telescopic cylinders 60, respectively connected to both ends of the extrusion plate 42. Preferably, the third telescopic cylinders 60 are symmetrically connected to the two end sides of the extrusion plate 42 along the axis of the extrusion rod 43.

[0039] In the preferred embodiment of this application, such as Figure 5As shown, the inlet hopper 70 includes a mounting flange 71, a guide channel 72, and a mounting block 73. The guide channel 72 is a channel with a funnel shape, formed by welding a panel and supporting ribs. The mounting flange 71 is located at the top of the guide channel 72. One end of the mounting block 73 is connected to the bottom end of the guide channel 72, and the other end extends towards the forming section 40. Optionally, to ensure the reliability and safety of the connection, a mounting block 74 is also included, penetrating the side wall of the guide channel 72 and fixed integrally with it, moving in tandem with it. The mounting block 74 has a through hole machined inside to maintain communication with the guide channel 72. Thus, by setting the guide channel in the shape of a funnel, the powder can automatically enter the forming section under gravity after entering the guide channel. The mounting block, which communicates with the guide channel, facilitates the rapid installation and fixation of the second telescopic cylinder while ensuring the overall strength of the entire device.

[0040] In the preferred embodiment of this application, such as Figure 1 and Figure 6 As shown, to reduce the impact of residual powder from the first telescopic part 20 on the consistency of the molded product, a third telescopic part 80 is also included, located on the top of the frame 50 between the frame 50 and the first telescopic part 20. Specifically, the fixed end of the third telescopic part 80 is mounted on the frame 50, and the movable end of the third telescopic part 80 is extendable downwards in the vertical direction. Preferably, the third telescopic part 80 is located directly above the travel path of the movable end of the first telescopic part 20. In this embodiment, the third telescopic part 80 is mounted on the second mounting plate 11 of the fixed part 10, directly above the travel path of the top block 22 of the first telescopic part 20. Thus, by using the third telescopic part located directly above the top block of the first telescopic part, the powder remaining on the side of the top block end of the first telescopic part can be peeled off under the action of the movable end of the third telescopic part, thereby reducing the risk of poor product consistency caused by the reduction of molding powder due to the removal of residual powder from the top block after compression.

[0041] Specifically, the third telescopic section 80 includes a mounting bracket 81, a pusher block 82, and a third telescopic cylinder 83. The mounting bracket 81 is disposed on the top surface of the frame 50 and extends upwards vertically. The fixed end of the third telescopic cylinder 83 is disposed on the top of the mounting bracket 81, and the movable end of the third telescopic cylinder extends downwards vertically. The pusher block 82 is disposed on the end side of the movable end of the third telescopic cylinder 83 and moves with the movable end of the third telescopic cylinder 83. Furthermore, to ensure safety during operation, a fastening nut 84 is also included at the connection between the pusher block 82 and the movable end of the third telescopic cylinder 83. Thus, by using the pusher block disposed on the movable end of the third telescopic cylinder, powder residue remaining on the top block of the first telescopic section can be easily peeled off, thereby reducing the risk of molding quality defects caused by residue after compression of the top block.

[0042] In summary, the third telescopic part provided by this utility model, through the pusher block set on the movable end of the third telescopic cylinder, can conveniently peel off the powder remaining on the top block of the first telescopic part, thereby reducing the risk of molding quality defects caused by the residue after the top block is compressed; through the third telescopic part set directly above the top block of the first telescopic part, under the action of the movable end of the third telescopic part, the powder remaining on the side of the top block end of the first telescopic part can be peeled off, thereby reducing the risk of poor product consistency caused by the reduction of molding powder due to the removal of the residual powder on the top block after compression.

[0043] Furthermore, regarding the selection of the telescopic cylinder in the preferred embodiment of this utility model, it can be a pneumatic cylinder, a hydraulic cylinder, or a combination thereof, or a mechanical structure that achieves the same function. The specific structural design of the telescopic cylinder should be readily conceived by those skilled in the art, and therefore will not be described in detail here.

[0044] Furthermore, the specific implementation methods of some control systems for powder forming devices, as well as the structures, principles, or other structural shapes that convert electrical signals into manipulation and visual scenes to achieve equivalent functions, should be easily conceived by those skilled in the art, and therefore will not be elaborated upon here.

[0045] In addition, it includes cables and other auxiliary equipment. For example, control switches, which should be easily conceived by those skilled in the art, will not be described in detail here.

[0046] The powder forming apparatus provided in the above embodiments of this application has at least the following characteristics:

[0047] The powder forming device provided in this embodiment of the application, through the connecting rod set between the first mounting plate and the second mounting plate, leaves a certain working space between the first telescopic part and the forming part, which facilitates the installation and maintenance of the telescopic part of the first telescopic part; the movable part of the first telescopic cylinder compresses the powder inside the forming part in a very convenient manner along the horizontal direction, with good mechanical properties and can provide sufficient compression force to meet the extrusion molding under high pressure; the coupling and rotary shaft set between the second telescopic cylinder and the stirring plate can compensate for the offset (including axial offset, radial offset, angular offset or combined offset) caused by inaccurate manufacturing and installation, deformation or thermal expansion during operation, as well as the impact during the transmission process; under the action of the rotary shaft, the linear motion of the telescopic cylinder is converted into the rotary motion, which in turn drives the stirring plate to flip in the inlet hopper, thereby improving the stirring effect on the powder in the inlet hopper; through the stirring plate fixed inside the inlet hopper Driven by the second telescopic cylinder, the moving end of the cylinder moves inside the inlet hopper, thus stirring the powder in the hopper. This prevents the powder from being affected by its particle size, shape, or inherent frictional characteristics, eliminating the need for manual intervention and effectively preventing clogging issues that can easily occur when the powder enters the mold cavity. This ensures that the entire process from feeding to extrusion is completed automatically, greatly improving production speed and efficiency while reducing labor input. The second dustproof ring, fitted around the extrusion rod and located at the connection between the extrusion rod and the molding cavity, effectively reduces the risk of powder leakage during operation, ensuring consistency in the powder molding process. The extrusion plate, through the extrusion rod, compresses the internal cavity of the molding cavity, thereby compressing the powder within the cavity. Combined with the first telescopic part, this achieves bidirectional extrusion of the powder within the molding cavity, providing sufficient extrusion pressure to form the powder.

[0048] The above description is merely a specific embodiment of this utility model. The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should all be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
