Description

Technical Field

[0001] This utility model relates to the technical field of alloy ball pressing equipment, specifically a preparation mechanism for alloy ball pressing. Background Technology

[0002] Alloy balls are spherical materials made by fusing two or more metals or metals with non-metals. They possess the excellent properties of multiple components, such as high strength, wear resistance, and corrosion resistance, and are widely used in bearings, grinding, medical devices, and other fields. Their functions vary depending on the application: reducing friction in bearings, efficiently crushing materials during grinding, and ensuring stable transmission in precision instruments. Due to the high hardness and complex composition of alloy materials, traditional casting is prone to defects such as porosity and segregation, while pressing can use molds to apply pressure to make the material dense and precisely control its size and performance. This is especially suitable for mass production of high-precision alloy balls, meeting the stringent requirements of industry for consistency and reliability. Existing alloy ball pressing preparation mechanism: Mix alloy raw materials according to the formula ratio. If it is in powder form, it needs to be dried and impurities removed. Fill the pretreated material into the concave mold cavity. Apply axial or radial pressure through a hydraulic press or special pressing equipment to make the material densify in the mold and form a spherical profile. After pressing, the formed alloy ball is taken out of the mold through the ejection mechanism. Most existing alloy ball pressing preparation mechanisms use ejector pins to push the formed alloy balls out from inside the lower die. The contact point between the ejector pin and the alloy ball may leave indentations or scratches. For brittle alloys, the ejection force may cause micro-cracks, reducing the product strength. This ejection method requires through holes corresponding to the ejector pins to be opened inside the lower die. During the pressing process, the ejector pins are prone to clogging due to powder, causing the ejection action to be stuck and affecting the continuity of production. Traditional ejector pin ejection is limited by the ejector pin layout and is difficult to adapt to alloy balls of different specifications. Therefore, we propose an alloy ball pressing preparation mechanism. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a preparation mechanism for pressing alloy balls. The demolding process is stable, there is no local stress, dimensional accuracy and internal integrity are ensured, the adaptability is strong, and the overall continuity of the alloy ball pressing work is improved. It can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a preparation mechanism for pressing alloy balls, comprising a box body, wherein each of the four slide rods is provided with a sliding rod, and a pressure plate is slidably connected between each of the four slide rods; an upper mold is fixedly connected to the lower surface of the pressure plate; a guide groove is provided on the front side of the box body; and a discharge mechanism is also included. The discharge mechanism includes a chute, a slider, a rotating column, and a mounting frame. The left and right inner walls of the guide channel are respectively provided with chute, and sliders are slidably connected inside the chute. A rotating column is rotatably connected to the side of the slider near the center of the box. A mounting frame is fixedly connected between the two rotating columns. The lower mold is connected inside the mounting frame by bolts. A support plate is provided between the left and right inner walls of the guide channel. The support plate is set in conjunction with the mounting frame. The demolding process is smooth and there is no local stress, which ensures dimensional accuracy and internal integrity. It has strong adaptability and improves the overall continuity of alloy ball pressing.

[0005] Furthermore, a microcontroller is provided on the left side of the enclosure. The input terminal of the microcontroller is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0006] Furthermore, the discharge mechanism also includes a guide rod, a lead screw, and a bellows. The guide rod is disposed between the front and rear inner walls of the right slide groove, and the lead screw is rotatably connected between the front and rear inner walls of the left slide groove. The left slider is threadedly connected to the lead screw. A bellows is provided between the front and rear inner walls of the left slider and the front and rear inner walls of the left slide groove. The lead screw is located inside the bellows to realize the sliding of the lower mold.

[0007] Furthermore, the discharge mechanism also includes a gear and a rack plate. The gear is fixedly sleeved on the outside of the rotating column on the right side, and the bottom wall of the slide groove on the right side is provided with a rack plate. The gear and the rack plate are installed together to realize the tilting and flipping of the lower mold.

[0008] Furthermore, a motor is installed inside the housing. The rear end of the motor's output shaft is fixedly connected to the front end of the lead screw, and the input end of the motor is electrically connected to the output end of the microcontroller to provide material discharge drive.

[0009] Furthermore, it also includes a support base, the lower surface of which is fixedly connected to the top of the four sliding rods. The upper end of the support base is equipped with a cylinder, the telescopic end of which is fixedly connected to the upper surface of the pressure plate. The air inlet of the cylinder is connected to the air outlet of an external air pump to provide a driving force for pressing the alloy ball.

[0010] Furthermore, a vibration motor is installed on the front side of the mounting bracket, and the input end of the vibration motor is electrically connected to the output end of the microcontroller to achieve rapid demolding of the molded alloy ball.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This alloy ball pressing preparation mechanism has the following advantages: The motor drives the lead screw to rotate. Because the slider is threadedly connected to the lead screw, the mounting frame and the lower die move forward as a whole inside the slide. When the mounting frame moves to the front end of the guide channel, as the slider continues to move, the gear rolls along the rack plate, driving the rotating column to rotate. This causes the mounting frame and the lower die to flip to an inclined state. The vibration motor is then started, and the vibration of the mounting frame causes the formed alloy ball to fall out of the lower die, realizing the discharge of the alloy ball. Compared with the traditional ejection method, this avoids mechanical damage, protects product precision, and ensures the continuity of alloy ball pressing work. Attached Figure Description

Detailed Implementation

[0014] 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.

[0015] Please see Figure 1-3This embodiment provides a technical solution: a preparation mechanism for pressing alloy balls, including a housing 1, with slide rods 2 respectively provided on the upper surface of the housing 1, and a pressure plate 3 slidably connected between each of the four slide rods 2. An upper mold 4 is fixedly connected to the lower surface of the pressure plate 3. A guide groove 6 is provided on the front side of the housing 1. It also includes a discharge mechanism 7. A microcontroller 10 is provided on the left side of the housing 1. The input terminal of the microcontroller 10 is electrically connected to an external power supply. It also includes a support base 11. The lower surface of the support base 11 is fixedly connected to the top ends of the four slide rods 2. A cylinder 1 is provided at the upper end of the support base 11. 2. The telescopic end of cylinder 12 is fixedly connected to the upper surface of pressure plate 3. The air inlet of cylinder 12 is connected to the air outlet of external air pump. The operator puts the alloy raw material into the mold cavity of lower mold 5 to complete the material preparation before pressing. The external air source supplies air to cylinder 12 through the conveying pipe to start the cylinder. The telescopic end of cylinder pushes pressure plate 3 to slide down along slide rod 2. Pressure plate 3 drives upper mold 4 to move down synchronously and close with lower mold 5 to apply pressure to the alloy raw material in the mold cavity to complete the pressing and forming of alloy ball. After pressing, cylinder 12 drives upper mold 4 to reset and wait for the next material discharge operation. The discharge mechanism 7 includes a chute 71, a slider 72, a rotating column 73, and a mounting frame 74. The left and right inner walls of the flow channel 6 are respectively provided with chute 71, and sliders 72 are slidably connected inside each chute 71. A rotating column 73 is rotatably connected to the side of each slider 72 near the center of the housing 1. A mounting frame 74 is fixedly connected between the two rotating columns 73. A lower mold 5 is bolted to the inside of the mounting frame 74. A support plate 9 is provided between the left and right inner walls of the flow channel 6. The support plate 9 cooperates with the mounting frame 74 (during the pressing process, the bottom surface of the mounting frame 74 contacts the upper surface of the support plate 9, preventing the mounting frame 74 from causing the lower mold 5 to deflect, while providing bottom support for the mounting frame 74 and the lower mold 5 to avoid damage). The force point is only on the rotating column 73). The discharge mechanism 7 also includes a guide rod 75, a lead screw 76, and a bellows 77. The guide rod 75 is located between the front and rear inner walls of the right slide 71. The lead screw 76 is rotatably connected between the front and rear inner walls of the left slide 71. The left slider 72 is threadedly connected to the lead screw 76. A bellows 77 is provided between the front and rear inner walls of the left slider 72 and the front and rear inner walls of the left slide 71. The lead screw 76 is located inside the bellows 77. The discharge mechanism 7 also includes a gear 78 and a rack plate 79. The gear 78 is fixedly sleeved on the outside of the right rotating column 73. A rack plate 79 is provided on the bottom wall of the right slide 71. The gear 78 and the rack plate 79 are fitted together. The interior of the housing 1 A motor 8 is provided, with its output shaft rear end fixedly connected to the front end of a lead screw 76. The input end of the motor is electrically connected to the output end of a microcontroller 10. A vibration motor 13 is mounted on the front side of a mounting bracket 74, with its input end electrically connected to the output end of the microcontroller 10. During the alloy ball production pressing, the lower die 5 is fixedly mounted on the mounting bracket 74 with bolts, maintaining coaxial alignment with the upper die 4. The microcontroller 10 starts the motor 8, and the output shaft of the motor 8 drives the lead screw 76 to rotate. The left slider 72, due to its threaded connection with the lead screw 76, slides forward along the left slide groove 71, while the right slider 72 slides synchronously along the guide rod 75, causing the mounting bracket 74 and the lower die 5 to move forward as a whole. During this process, the bellows 77... As the slider 72 moves and extends, it prevents raw material debris from contaminating the lead screw 76. When the mounting frame 74 moves forward, the central axes of the two rotating columns 73 are collinear. When this central axis passes the foremost point of the upper surface of the support plate 9, the gear 78 on the right rotating column 73 meshes with the rack plate 79 (to prevent the mounting frame 74 from tilting forward or backward due to lack of bottom support). As the slider 72 continues to move, the gear 78 rolls along the rack plate 79, driving the rotating column 73 to rotate, causing the mounting frame 74 and the lower mold 5 to flip to an inclined state. Then, the microcontroller 10 starts the vibration motor 13, and the vibration of the mounting frame 74 causes the formed alloy ball to fall out of the lower mold 5 and slide out and be collected through the guide groove 6.

[0016] The working principle of the alloy ball pressing preparation mechanism provided by this utility model is as follows: During alloy ball production and pressing, the lower mold 5 is fixedly installed on the mounting frame 74 by bolts, and is coaxially aligned with the upper mold 4. The operator puts the alloy raw material into the mold cavity of the lower mold 5 to complete the material preparation before pressing. The external air source supplies air to the cylinder 12 through the conveying pipe to start the cylinder. The cylinder extension end pushes the pressure plate 3 to slide down along the slide rod 2. The pressure plate 3 drives the upper mold 4 to move down synchronously and close with the lower mold 5, applying pressure to the alloy raw material in the mold cavity to complete the pressing and forming of the alloy ball. After pressing, the cylinder 12 drives the upper mold 4 to reset, waiting for the next material discharge operation. The microcontroller 10 starts the motor 8. The output shaft of the motor 8 drives the lead screw 76 to rotate. The left slider 72, because it is threadedly connected to the lead screw 76, slides forward along the left slide groove 71. The right slider 72 slides synchronously along the guide rod 75, driving the mounting frame 74 and the lower mold 5 to move forward as a whole. During this process, the corrugated pipe 77 moves and extends with the slider 72 to avoid the raw material breaking. When the mounting bracket 74 moves forward, the central axes of the two rotating columns 73 are collinear. When this central axis passes the foremost point of the upper surface of the support plate 9, the gear 78 on the right rotating column 73 meshes with the rack plate 79 (to prevent the mounting bracket 74 from tilting forward or backward due to lack of bottom restraint support during forward movement). As the slider 72 continues to move, the gear 78 rolls along the rack plate 79, causing the rotating column 73 to rotate, thus tilting the mounting bracket 74 and the lower mold 5. In the state, the microcontroller 10 starts the vibration motor 13, and the mounting bracket 74 vibrates to cause the formed alloy ball to fall out of the lower mold 5 and slide out through the guide groove 6 for collection (in order to prevent the vibration motor 13 from winding, so that the maximum rotation angle of the rotating column is 180 degrees, the gear 78 and the rack plate 79 are key limiting components. The number of teeth of the gear 78 and the effective meshing length of the rack plate 79 are matched, so that the rolling distance of the gear 78 from the initial meshing point to the final meshing point corresponds exactly to half a turn of the gear 78).

[0017] It is worth noting that the microcontroller 10 disclosed in the above embodiments can be a PIC16F877A, the motor 8 can be a Y180L-615, and the vibration motor 13 can be a HY-0.1. The microcontroller 10 controls the operation of the motor 8 and the vibration motor 13 using methods commonly used in the prior art.
