Description

Technical Field

[0001] This utility model relates to the field of feeding structure technology, specifically to a swing arm double feeding structure for an electric-driven powder metallurgy pressing and molding machine. Background Technology

[0002] The electric-driven powder metallurgy pressing and forming machine is a special processing equipment that uses a high-performance servo motor as the core drive unit and relies on a precision ball screw to achieve precise power transmission and accurate displacement control. By applying stable high pressure to the metal powder raw material, it causes the powder particles to be tightly bonded and densely formed in a customized mold cavity.

[0004] In the feeding stage of an electric-driven powder metallurgy pressing and forming machine, the existing technology often uses the back-blowing method to achieve powder feeding. Although it can meet the basic feeding requirements, it has obvious limitations when adapting to a dual feeding mechanism. It is necessary to configure independent back-blowing components for the two feeding channels, which not only increases the number of parts and structural complexity of the equipment, but also requires more space for installation and layout, resulting in an increase in the overall size of the equipment, and ultimately driving up the manufacturing cost and purchase price of the equipment. Therefore, in order to address the above problems, a swing arm dual feeding structure for an electric-driven powder metallurgy pressing and forming machine is proposed. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0018] Please see Figures 1-7 This utility model provides a technical solution: A swing-arm double-feeding structure for an electrically driven powder metallurgy pressing and molding machine includes a molding machine 1 and an arc-shaped track 2. A carbox assembly 4 and a vibration control assembly 6 are slidably connected to the inner side of the arc-shaped track 2. A storage assembly 5 is installed inside the carbox assembly 4. The carbox assembly 4 includes a first arc-shaped track plate 41. An assembly groove 42, a guide groove 43, and a ramp 45 are opened on the inner side of the first arc-shaped track plate 41. The storage assembly 5 includes a storage shell 51. A first permanent magnet block 52 is fixedly connected to the inner side of the storage shell 51 near the upper end. A storage trough 53 is opened on the inner side of the storage shell 51. An extension cylinder 54 is fixedly connected to the position of the storage shell 51 near the lower end. A connecting rod 55 is fixedly connected to the inner side of the extension cylinder 54. A sealing block 56 is fixedly connected to the bottom end of the connecting rod 55. A first slope 57 is opened at the upper end of the sealing block 56. A second slope 58 is opened at the lower end of the sealing block 56.

[0019] As a further implementation of this solution, an arc-shaped track 2 is fixedly connected to the inner side of the molding machine 1. The arc-shaped track 2 is set to be arc-shaped. An electric telescopic rod 3 is rotatably connected to the right side of the lower mold of the molding machine 1. An assembly block is fixedly connected to the piston rod end of the electric telescopic rod 3. The electric telescopic rod 3 is fixedly connected to the right-side box car assembly 4 through the assembly block. Through the above settings, the arc-shaped track 2 is adapted to the sliding trajectory of the box car assembly 4 and the vibration control assembly 6 to realize the function of swing arm feeding. The assembly block ensures that the electric telescopic rod 3 and the box car assembly 4 are firmly connected, which can realize the precise translation of the feeding mechanism, ensure that the feeding position is precisely aligned with the mold groove, and improve the feeding accuracy and process continuity. As a further implementation of this solution, there are two box car components 4. The two box car components 4 are separated by a fixing block. The front and rear ends of the first arc-shaped rail plate 41 are slidably connected between the two arc-shaped rails 2. With the above settings, the double box car component 4 is designed to meet the dual feeding requirements without the need to add an independent feeding component. The fixing block enhances the structural stability, and the sliding connection ensures smooth movement of the feeding mechanism, reducing the complexity of the equipment and the space occupied. As a further implementation of this solution, sliders are fixedly connected to both sides of the storage shell 51. The storage shell 51 is embedded in the assembly groove 42. The sliders of the storage shell 51 are slidably connected to the inside of the guide groove 43. Through the above arrangement, the sliding cooperation between the sliders and the guide groove 43 enables the storage shell 51 to move up and down in a directional manner, avoiding deviation that could lead to poor material feeding or raw material leakage. At the same time, it limits the range of motion of the storage shell 51, preventing the extension cylinder 54 from disengaging from the ramp 45 and ensuring the stability of equipment operation. As a further implementation of this solution, the bottom end of the storage shell 51 is fixedly connected to the top end of the spring 44, and the bottom end of the spring 44 is fixedly connected to the assembly groove 42 opened in the first arc-shaped rail plate 41. There is a movable gap between the storage shell 51 and the lower end of the assembly groove 42. Through the above settings, the spring 44 plays a buffering role, which can alleviate the impact force when the storage shell 51 moves, avoid excessive collision damage with the first arc-shaped rail plate 41, extend the service life of the unloading component, and provide sufficient space for the lifting and lowering of the storage shell 51 to ensure smooth unloading action. As a further implementation of this solution, the second slope 58 of the sealing block 56 can fit against the inner side of the groove 45. A gap is left between the sealing block 56 and the extension cylinder 54. Through the above settings, the fit between the second slope 58 and the groove 45 achieves sealing during raw material storage, preventing raw material overflow and leakage. The reserved gap provides a channel for raw material flow during feeding, ensuring that the raw material enters the mold quickly and accurately, taking into account both leakage prevention and feeding efficiency. As a further implementation of this solution, the vibration control component 6 includes a second arc-shaped rail plate 61, which is slidably connected between two arc-shaped rails 2. A folding plate 62 is fixedly connected to the top of the second arc-shaped rail plate 61, and the folding plate 62 is fixedly connected to the housing of the servo motor 63. A turntable 64 is fixedly connected to the end of the main shaft of the servo motor 63, and a second permanent magnet block 65 is fixedly connected to the inner side of the turntable 64. The second permanent magnet block 65 is aligned vertically with the first permanent magnet block 52 and magnetically attracted. Through the above settings, the magnetic attraction can accurately drive the material storage shell 51 to rise and fall, eliminating the need for a complex transmission structure, reducing the number of parts and equipment complexity. The sliding connection ensures the accurate positioning of the vibration control component 6, improves the controllability and consistency of the feeding action, changes the original back-blowing feeding method, and reduces cost input.

[0020] Workflow: During use, raw materials are filled into the storage tank 53. Before this, the sealing block 56 is attached to the inner side of the slope 45 via the second slope 58. The sealing block 56 and the connecting rod 55 are fixed to the storage shell 51, providing support for the storage shell 51. The sealing block 56 prevents the raw materials inside the storage tank 53 from overflowing. After the raw materials are assembled, the electric telescopic rod 3 is activated to move the entire box truck assembly 4 and the entire storage assembly 5 to the left. When the left end of the storage assembly 5 is aligned with the lower mold... After the grooves are aligned, the electric telescopic rod 3 is stopped, and the vibration control assembly 6 is moved to the right until the second arc-shaped rail plate 61 is in contact with the side of the first arc-shaped rail plate 41. At this point, the servo motor 63 is started, which drives the turntable 64 and the second permanent magnet block 65 to rotate. When the second permanent magnet block 65 is aligned with the first permanent magnet block 52, the second permanent magnet block 65 will generate a magnetic attraction force on the first permanent magnet block 52. The magnetic attraction force between multiple first permanent magnet blocks 52 and multiple second permanent magnet blocks 65 can... Overcoming the gravity and friction of the storage shell 51 under full load, the storage shell 51 moves upward. The storage shell 51 slides inside the assembly groove 42 and guide groove 43. The extension cylinder 54 extends into the slope groove 45. The range of motion of the storage shell 51 will not cause the extension cylinder 54 to detach from the slope groove 45, thus preventing the raw material from entering the assembly groove 42. When the sealing block 56 moves upward, the raw material will enter the slope groove 45 through the gap between the sealing block 56 and the extension cylinder 54, and then fall into the groove of the mold. The spring 44 can buffer the movement of the storage shell 51 to prevent the storage shell 51 from being damaged due to excessive collision with the first arc-shaped rail plate 41. After the material is unloaded, the vibration control component 6 is pushed to reset. At the same time, the electric telescopic rod 3 is controlled to move the box car component 4 away from the lower mold. The upper mold of the molding machine 1 is controlled to move downward, thereby extruding and molding the raw material inside the groove of the lower mold. Based on the same principle, the raw material inside the next storage component 5 is unloaded and stamped again.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
