Description

Technical Field

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

[0002] Metal powder molding equipment is a specialized machine that applies pressure to press metal powders, such as iron, copper, stainless steel, and aluminum, into blanks or parts with specific shapes and densities. This process shapes the metal powder, providing the basic blanks for subsequent sintering, machining, and other processes. It controls the dimensional accuracy, density uniformity, and surface quality of the blanks, influencing the performance of the final product. The metal powder molding equipment operates by using high-pressure fluid generated by a hydraulic system to drive a punch in conjunction with a mold, applying pressure to the metal powder to shape it into a blank of a specific shape. It is a core piece of equipment in fields such as powder metallurgy, hard alloys, and magnetic materials. Because the powder moves with other powder particles during the molding process, it is necessary to perform centralized powder movement operations.

[0003] In related technologies, during the use of metal powder molding equipment, a downward-sloping guide rail is generally installed at the discharge position of the metal powder molding equipment to move and guide the molded powder block.

[0004] However, in the current use of metal powder molding equipment, the guide rail can only guide the powder block downwards after molding. The powder that moves with the powder block will move to other stations through the guide rail, which can easily cause powder waste and affect the powder concentration effect of the metal powder molding equipment.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4This utility model provides a technical solution: a molding equipment for metal powder processing, including a molding press 1 and a material discharge concentrating mechanism. A punch 2 is installed on the top of the inner side of the molding press 1, and a mold 3 is installed on the bottom of the inner side of the molding press 1. While guiding the material at the top of the mold 3 for discharge, the powder moving with the material is filtered and concentrated, avoiding the situation where the powder is difficult to concentrate when the material moves during the use of the mold 3, resulting in waste of powder material. Therefore, the powder discharge concentration effect of the molding press 1 and the mold 3 is improved.

[0031] Reference Figures 1-4 In a preferred embodiment, the material collection mechanism includes a material discharge seat 4, which is movably connected to the front side of the mold 3. A material discharge plate 5 is fixedly connected to the inner wall of the material discharge seat 4. A collection port 6 is opened at the top of the material discharge plate 5. A filter screen 7 is movably connected inside the collection port 6. A collection strip 8 is fixedly connected to the bottom of the inner wall of the collection port 6. The material collection mechanism is fixedly connected to the top of the material discharge seat 4. When the formed powder block moves forward out of the mold 3, the material discharge seat 4, in conjunction with the material discharge plate 5, receives and guides the powder block. At the same time, the collection port 6, in conjunction with the collection strip 8 and the filter screen 7, collects and guides the powder block. During the movement of the final block, the powder is filtered and concentrated. The concentrated powder removal mechanism includes a powder removal frame 9, a powder removal plate 10, and powder removal brushes 11. The powder removal frame 9 is fixedly connected to the top of the discharge seat 4, the powder removal plate 10 is movably connected to the inner side of the discharge seat 4, and the powder removal brushes 11 are installed on both sides of the bottom of the powder removal plate 10. When the filter screen 7 works in conjunction with the discharge plate 5, the powder adhering to the surface of the powder block that is guided and moved at the top of the discharge plate 5 can be removed, thus avoiding the situation where the discharge plate 5 has difficulty removing the powder adhering to the surface of the powder block, thereby improving the powder removal effect of the discharge plate 5.

[0032] Reference Figures 2-3 In a preferred embodiment, a screw cylinder 12 is fixedly connected to the top of the material support frame 9, and a screw holder 13 is threadedly connected inside the screw cylinder 12. The bottom of the screw holder 13 is connected to the top of the material support plate 10, which can connect and support the material support plate 10 and the material support frame 9, and provide a medium for the user to adjust the position of the material support plate 10. This improves the flexibility of the material support plate 10. A connecting groove 14 is opened on the top of the material support plate 10, and a connecting seat 15 is magnetically connected inside the connecting groove 14. The top of the connecting seat 15 is fixedly connected to the bottom of the screw holder 13, which can rotate and prevent separation between the screw holder 13 and the material support plate 10, thus preventing the screw holder 13 from separating from the material support plate 10 during use. This improves the connection effect between the screw holder 13 and the material support plate 10.

[0033] Reference Figures 2-3In a preferred embodiment, a receiving port 16 is provided at the bottom right side of the discharge seat 4. The receiving port 16 is movably connected to a receiving box 17 located at the bottom of the discharge plate 5. This allows for the centralized collection of powder filtered and concentrated by the filter screen 7 and the collection port 6, enabling users to perform unified processing of the concentrated powder. This improves the receiving and holding capacity of the discharge seat 4. A magnetic plate 18 is embedded and connected to the front left side of the receiving box 17, and a magnetic suction plate 19, which is magnetically connected to the magnetic plate 18, is embedded and connected to the front right side of the discharge seat 4. This allows for magnetic positioning of the receiving box 17 and the discharge seat 4, preventing the receiving box 17 from being difficult to position during use. This improves the ease of positioning the receiving box 17.

[0034] Reference Figures 2-4 In a preferred embodiment, a fixing bracket 20 is fixedly connected to the rear side of both sides of the discharge seat 4, and a fixing plate 21 is movably connected to the inner side of the fixing bracket 20. This allows for the installation and fixing of the discharge seat 4 and the mold 3, avoiding the situation where the discharge seat 4 is difficult to install and fix to the front side of the mold 3. This improves the ease of installation and fixing of the discharge seat 4. The outer side of the fixing bracket 20 is provided with a screw hole 22, and the screw hole 22 is internally threaded with a stud 23 connected to the fixing plate 21. This provides a medium for the user to apply a clamping force to the fixing plate 21, avoiding the situation where the fixing plate 21 is difficult to fix. This improves the force application and fixing effect of the fixing plate 21.

[0035] Specifically, the working process or working principle of this metal powder processing molding equipment is as follows: During use, the hand-held ejector seat 4 is moved to the front of the mold 3, and the rear side of the ejector seat 4 contacts the front side of the mold 3, ensuring that the ejector seat 4 fits snugly against the mold 3. Then, the hand-held stud 23 is rotated to apply an inward threaded thrust to the fixing plate 21 by rotating the threaded hole 22, causing the fixing plate 21 to move inward and contact the surface of the mold 3, tightly abutting against the fixing frame 20, thus clamping and fixing the ejector seat 4 to the front of the mold 3. Then, the hand-held... The receiving box 17 is installed at the bottom of the discharge plate 5 through the receiving port 16, preparing for the subsequent centralized reception and containment of powder. At this time, the magnetic plate 18 and the magnetic suction plate 19 contact each other, performing magnetic positioning between the receiving box 17 and the discharge seat 4. Subsequently, according to the actual size of the powder block formed by the mold 3 and the punch 2 during operation, the hand-held screw frame 13 rotates in conjunction with the screw barrel 12 and the material guide frame 9, applying a lifting and lowering threaded thrust to the material guide plate 10, causing the material guide plate 10 to drive the material guide brush 11 to adjust the material guide height. In preparation for the subsequent brushing of powder off the surface of the powder block by the brush 11, the connecting seat 15 moves with the screw frame 13 inside the connecting groove 14 to connect the screw frame 13 and the brushing plate 10 to prevent separation. After the molding machine 1, together with the punch 2 and the mold 3, performs molding of the external powder, the powder block moves forward out of the mold 3. The discharge seat 4, together with the discharge plate 5, receives and guides the powder block that has moved out of the mold 3. When the powder block moves forward after being guided by the discharge plate 5, the brush 11 brushes the powder attached to the surface of the powder block. At the same time, the collection port 6, together with the collection strip 8 and the filter screen 7, filters and collects the powder that moves with the powder block and falls off the surface of the powder block. The powder block after being filtered by the filter screen 7 continues to move forward, while the powder moves downward through the filter screen 7 and the collection port 6 due to gravity. At this time, the receiving box 17 receives and contains the powder collected by the filter screen 7 and the collection port 6 so that the user can perform unified processing of the collected powder later.

[0036] It should be noted that the molding machine 1, punch 2 and mold 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
