Description

Technical Field

[0001] This utility model relates to the field of powder forming machine technology, and in particular to a pin seat plate suitable for powder forming machines. Background Technology

[0002] During the operation of a powder forming machine, the pin seat plate is a key component, and its structural design directly affects the stability and production efficiency of the equipment.

[0003] Traditional pin-mounted base plates present numerous problems in pin installation. On one hand, the connection between the pin and the base plate is often quite simple. During equipment operation, vibration and other external forces can easily cause the pin to loosen, affecting the positional accuracy of the components connected to the pin and preventing the powder forming process from achieving the desired results. On the other hand, when it is necessary to adjust the position of the components connected to the pin to adapt to different powder forming process requirements or to adapt the position after mold installation or replacement, the traditional base plate structure is cumbersome to operate, usually requiring the complete removal of the pin, which greatly reduces equipment maintenance efficiency and increases downtime and production costs.

[0004] Therefore, we propose a pin seat plate suitable for powder forming machines. Utility Model Content

[0005] The main purpose of this utility model is to provide a pin seat plate suitable for powder molding machines. In order to prevent the pins from loosening and to avoid problems such as cumbersome operation in adjusting the position of components and adapting the position after mold installation and replacement, the stability, production efficiency and maintenance efficiency of the equipment are improved, and downtime and production costs are reduced. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A pin seat plate suitable for a powder forming machine includes a seat plate body, which is a circular plate structure. Four arc-shaped grooves are evenly distributed along the circumference of the seat plate body. Multiple mounting holes are provided at the upper part of each arc-shaped groove. Pin bodies are connected within each mounting hole. Each mounting hole is a stepped hole, including a large-diameter hole at the top and a small-diameter hole at the bottom. An arc-shaped plate is disposed inside the large-diameter hole, and an internal thread is provided on the inner wall of the small-diameter hole. An external thread is provided on the outer wall of the pin body, and the external thread connects to the internal thread. The pin body passes through the mounting hole and is threadedly connected to a fixing nut.

[0008] The outer wall of the fixing nut is provided with a plurality of limiting holes in a ring, and the inner wall of the arc plate is provided with a groove. A limiting ball that can be inserted into the limiting hole is provided in the groove. The end of the limiting ball away from the limiting hole is fixedly connected to the arc plate by a spring.

[0009] By adopting the above technical solution, since the external thread on the outer wall of the pin body is compatible with the internal thread on the inner wall of the small-diameter hole, the operator can pass the pin body through the mounting hole and rotate the pin body to make the external thread and internal thread connected, thus initially fixing the pin body in the mounting hole of the base plate body.

[0010] After the pin body passes through the mounting hole, a fixing nut is threaded onto its protruding part. The operator tightens the fixing nut to further enhance the connection stability between the pin body and the base plate body and prevent the pin body from loosening.

[0011] During the tightening of the fixing nut, when the limiting hole of the fixing nut rotates to the position corresponding to the limiting ball in the groove of the inner wall of the arc plate, the spring will push the limiting ball to insert into the limiting hole. After the limiting ball is inserted into the limiting hole, it will limit the fixing nut and restrict its rotation. When the base plate body is subjected to vibration or other external forces during the operation of the powder forming machine, this limiting structure can effectively prevent the fixing nut from loosening on its own, thereby ensuring the stable installation of the pin body.

[0012] Furthermore, the base plate body has a central hole at its center for mounting in conjunction with the rotating shaft of the rotary powder forming machine.

[0013] By adopting the above technical solution, the operator can accurately fit the center hole into the rotating shaft. Since the dimensional accuracy of the rotating shaft matches the design accuracy of the center hole, it can ensure that the base plate body is in the correct position in both the horizontal and vertical directions, guarantee the concentricity of the base plate and the rotating shaft, and avoid the base plate from shaking or becoming eccentric during rotation due to installation deviation, thereby affecting the accuracy and quality of powder forming.

[0014] Furthermore, a rubber pad is provided at the bottom end of the large-diameter hole.

[0015] By adopting the above technical solution, the rubber pad mainly plays the roles of buffering, sealing and auxiliary fixation.

[0016] Furthermore, the fixing nut is located inside the large-diameter hole, and the fixing nut is positioned directly above the rubber pad.

[0017] By adopting the above technical solution, when the fixing nut tightens the pin body, it squeezes the rubber pad. The elasticity of the rubber pad causes it to generate a reverse elastic force, which applies axial preload to the pin body, enhances the tightness of the connection between the pin body and the seat plate body, prevents loosening due to external forces such as vibration and impact during operation, and ensures long-term stability. At the same time, the tightening action, with the help of the rubber pad's characteristics, makes the external thread of the pin body fit more tightly with the internal thread of the small-diameter hole, eliminates thread gaps, and improves connection reliability.

[0018] When the vibration generated by the molding machine is transmitted to the pin seat plate, the rubber pad acts as a buffer element. Through elastic deformation, it converts the vibration energy into elastic potential energy, reduces the impact of vibration on the pin connection, reduces the risk of thread wear and loosening, and extends the service life of the pin and seat plate. For instantaneous impact forces during the powder molding process, such as the impact when the mold opens and closes, the rubber pad can quickly deform and buffer, preventing the impact force from acting directly on the fixing nut and pin, and ensuring that the pin seat plate works normally under complex working conditions.

[0019] In terms of sealing and protection, the fixing nut and the rubber gasket form a relatively sealed space in the large-diameter hole, which effectively prevents dust and impurities from entering the mounting hole, especially the threaded part of the pin, preventing thread wear and jamming, protecting the thread structure, and improving the reliability and stability of operation. In addition, the rubber gasket also has a moisture-proof function, reducing the contact between moisture in the air and the pin and the base plate body, preventing the metal parts from rusting and corroding, which is of great significance for extending the service life of the pin base plate in humid environments.

[0020] Furthermore, the outer diameter of the pin body matches the inner diameter of the arc-shaped groove, and the pin body is slidably connected to the arc-shaped groove.

[0021] By adopting the above technical solution, the outer diameter of the pin body matches the inner diameter of the arc-shaped slide, which gives the pin body a clear space to move in the arc-shaped slide. The arc-shaped slide, like a track, provides positional constraints for the pin body, ensuring that the pin body can only move along the trajectory of the arc-shaped slide. During the operation of the rotary powder forming machine, when it is necessary to adjust the position of the parts connected to the pin, the arc-shaped slide guides the movement of the pin body. When the position needs to be adjusted after the mold is installed or replaced to adapt to different powder forming process requirements, the pin body can move accurately to the appropriate position under the guidance of the arc-shaped slide, ensuring the accuracy of the position of the relevant parts.

[0022] This connection method makes it easier to replace parts connected by pins. Simply loosen the fixing nut on the pin body and slide it into the appropriate position in the arc-shaped groove, without having to completely remove the pin, thus improving the efficiency of equipment maintenance.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) This utility model provides a pin seat plate suitable for powder forming machines. Through a unique installation structure design, it significantly enhances the connection stability between the pin body and the seat plate body. The external thread on the outer wall of the pin body matches the internal thread on the inner wall of the small-diameter hole of the mounting hole, achieving initial fixation of the pin body. On this basis, a fixing nut is threadedly connected to the protruding part of the pin body and tightened to further strengthen the connection. More importantly, during the tightening of the fixing nut, when the limiting hole rotates to the position corresponding to the limiting ball in the groove of the inner wall of the arc plate, the spring pushes the limiting ball into the limiting hole, which plays a limiting role on the fixing nut. This effectively prevents the fixing nut from loosening on its own due to vibration or other external forces on the seat plate body during the operation of the powder forming machine, thereby ensuring the stable installation of the pin body and providing a solid guarantee for the stable operation of the equipment.

[0025] (2) This utility model provides a pin seat plate suitable for powder forming machines. The design of the pin body and the arc-shaped slide groove greatly improves the convenience of adjusting the position of the parts connected to the pin. The outer diameter of the pin body matches the inner diameter of the arc-shaped slide groove, giving the pin body a clear space to move within the arc-shaped slide groove. The arc-shaped slide groove acts like a precise track, providing positional constraints for the pin body and ensuring that it can only move along the trajectory of the arc-shaped slide groove. When the powder forming machine is working, if it is necessary to adjust the position of the parts connected to the pin to adapt to different powder forming process requirements, or to adapt the position after mold installation or replacement, the pin body can move precisely to the appropriate position under the guidance of the arc-shaped slide groove, ensuring the accuracy of the position of the relevant parts. Moreover, when replacing the parts connected to the pin, the operation is simpler. It is only necessary to loosen the fixing nut and slide the pin body to the appropriate position in the arc-shaped slide groove without completely removing the pin, which greatly improves the efficiency of equipment maintenance, reduces downtime, and lowers production costs.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] To prevent issues such as loose pins and cumbersome adjustments to component positions and repositioning after mold installation and replacement, thereby improving equipment stability, production efficiency, and maintenance efficiency, and reducing downtime and production costs, such as... Figure 1 , Figure 2 , Figure 3 As shown, a pin seat plate suitable for a powder forming machine includes a seat plate body 1, which is a circular plate structure. The seat plate body 1 has four arc-shaped grooves 2 evenly distributed along the circumference. The upper part of the arc-shaped grooves 2 is provided with multiple mounting holes 3. A pin body 6 is connected in the mounting holes 3. The mounting holes 3 are stepped holes, and the mounting holes 3 include a large-diameter hole 4 at the upper part and a small-diameter hole 5 at the lower part. An arc-shaped plate 9 is provided inside the large-diameter hole 4. An internal thread 7 is provided on the inner wall of the small-diameter hole 5. An external thread 8 is provided on the outer wall of the pin body 6. The external thread 8 is connected to the internal thread 7. The pin body 6 passes through the mounting holes 3 and is threadedly connected to a fixing nut 10.

[0032] The outer wall of the fixing nut 10 is provided with a plurality of limiting holes 11 in a ring, and the inner wall of the arc plate 9 is provided with a groove 12. A limiting ball 13 that can be inserted into the limiting hole 11 is provided in the groove 12. The end of the limiting ball 13 away from the limiting hole 11 is fixedly connected to the arc plate 9 by a spring 14.

[0033] When in use, since the external thread 8 on the outer wall of the pin body 6 is compatible with the internal thread 7 on the inner wall of the small diameter hole 5, the operator can pass the pin body 6 through the mounting hole 3 and rotate the pin body 6 to make the external thread 8 and internal thread 7 threadedly connected, thus initially fixing the pin body 6 in the mounting hole 3 of the base plate body 1.

[0034] After the pin body 6 passes through the mounting hole 3, a fixing nut 10 is threaded onto its protruding part. The operator tightens the fixing nut 10 to further enhance the connection stability between the pin body 6 and the seat plate body 1 and prevent the pin body 6 from loosening.

[0035] During the tightening of the fixing nut 10, when the limiting hole 11 of the fixing nut 10 rotates to the position corresponding to the limiting ball 13 in the groove 12 of the inner wall of the arc plate 9, the spring 14 will push the limiting ball 13 to insert into the limiting hole 11. After the limiting ball 13 is inserted into the limiting hole 11, it will limit the fixing nut 10 and restrict the rotation of the fixing nut 10. When the base plate body 1 is subjected to vibration or other external forces during the operation of the powder forming machine, this limiting structure can effectively prevent the fixing nut 10 from loosening on its own, thereby ensuring the stable installation of the pin body 6.

[0036] For example, such as Figure 1 As shown, the present invention also includes a center hole 15 at the center of the base plate body 1 for mounting in conjunction with the rotating shaft of the rotary powder forming machine.

[0037] During use, the operator accurately fits the center hole 15 into the rotating shaft. Since the dimensional accuracy of the rotating shaft matches the design accuracy of the center hole 15, it can ensure that the base plate body 1 is in the correct position in both the horizontal and vertical directions, ensuring the concentricity of the base plate and the rotating shaft, and avoiding the base plate from shaking or becoming eccentric during rotation due to installation deviation, thereby affecting the accuracy and quality of powder forming.

[0038] For example, such as Figure 2 As shown, the present invention also includes a rubber pad 16 provided at the bottom end of the large-diameter hole 4.

[0039] When in use, the rubber pad 16 mainly serves to cushion, seal, and provide auxiliary fixation.

[0040] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a fixing nut 10 located inside the large-diameter hole 4, and the fixing nut 10 located directly above the rubber pad 16.

[0041] When the fixing nut 10 tightens the pin body 6, it squeezes the rubber pad 16. The elasticity of the rubber pad 16 causes it to generate a reverse elastic force, which applies an axial preload to the pin body 6, enhances the tightness of the connection between the pin body 6 and the seat plate body 1, prevents loosening due to external forces such as vibration and impact during operation, and ensures the stability of long-term use. At the same time, the tightening action, with the help of the characteristics of the rubber pad 16, makes the external thread 8 of the pin body 6 fit more tightly with the internal thread of the small diameter hole 5, eliminates thread gaps, and improves the reliability of the connection.

[0042] When the vibration generated by the molding machine is transmitted to the pin seat plate 1, the rubber pad 16 acts as a buffer element, converting the vibration energy into elastic potential energy through elastic deformation, reducing the impact of vibration on the pin connection part, reducing the risk of thread wear and loosening, and extending the service life of the pin and seat plate body 1. For the instantaneous impact force in the powder molding process, such as the impact when the mold is opened and closed, the rubber pad 16 can quickly deform and buffer, avoiding the impact force from acting directly on the fixing nut 10 and the pin, ensuring that the pin seat plate 1 works normally under complex working conditions.

[0043] In terms of sealing and protection, the fixing nut 10 and the rubber gasket 16 form a relatively sealed space in the large-diameter hole 4, which effectively prevents dust and impurities from entering the mounting hole 3, especially the threaded part of the pin, preventing thread wear and jamming, protecting the thread structure, and improving the reliability and stability of operation. In addition, the rubber gasket 16 also has a moisture-proof function, reducing the contact between moisture in the air and the pin and the base plate body 1, preventing the metal parts from rusting and corroding, which is of great significance for extending the service life of the pin base plate in humid environments.

[0044] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a pin body 6 whose outer diameter matches the inner diameter of the arc-shaped groove 2, and the pin body 6 is slidably connected to the arc-shaped groove 2.

[0045] During use, the outer diameter of the pin body 6 matches the inner diameter of the arc-shaped slide 2, which gives the pin body 6 a clear space to move within the arc-shaped slide 2. The arc-shaped slide 2 acts like a track, providing positional constraints for the pin body 6 and ensuring that the pin body 6 can only move along the trajectory of the arc-shaped slide 2. During the operation of the rotary powder forming machine, when it is necessary to adjust the position of the parts connected to the pin, the arc-shaped slide 2 guides the movement of the pin body 6. When the position needs to be adjusted after the mold is installed or replaced to adapt to different powder forming process requirements, the pin body 6 can move precisely to the appropriate position under the guidance of the arc-shaped slide 2, ensuring the accuracy of the position of the relevant parts.

[0046] This connection method makes it easier to replace the parts connected by the pin. Simply loosen the fixing nut 10 of the pin body 6 and slide it into the appropriate position in the arc-shaped groove 2, without having to completely remove the pin, thus improving the efficiency of equipment maintenance.

[0047] It should be noted that this utility model is a pin seat plate suitable for a powder forming machine. The center hole 15 at the center of the seat plate body 1 is accurately fitted into the rotating shaft of the rotary powder forming machine. The matching dimensional accuracy of the two ensures that the seat plate body 1 is correctly positioned in the horizontal and vertical directions, and ensures the concentricity with the rotating shaft.

[0048] Since the external thread 8 on the outer wall of the pin body 6 is compatible with the internal thread 7 on the inner wall of the small diameter hole 5, the pin body 6 is passed through the mounting hole 3 and rotated so that the external thread 8 and the internal thread 7 are threadedly connected, thus achieving the initial fixation of the pin body 6 in the mounting hole 3 of the base plate body 1.

[0049] A fixing nut 10 is threaded onto the protruding part of the pin body 6 that passes through the mounting hole 3. The operator tightens the fixing nut 10 to enhance the connection stability between the pin body 6 and the base plate body 1.

[0050] During the tightening process of the fixing nut 10, when its limiting hole 11 rotates to the position corresponding to the limiting ball 13 in the groove 12 of the inner wall of the arc plate 9, the spring 14 pushes the limiting ball 13 into the limiting hole 11, restricting the rotation of the fixing nut 10 and preventing it from loosening on its own due to external force when the equipment is working.

[0051] When the rotary powder forming machine is in operation, if it is necessary to adjust the position of the component connected to the pin, since the outer diameter of the pin body 6 matches and slides with the inner diameter of the arc-shaped slide groove 2, the pin body 6 can be precisely moved to the appropriate position along its trajectory under the guidance of the arc-shaped slide groove 2, so as to meet the requirements of different powder forming processes, without the need to completely remove the pin.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
