[0030] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar expressions used herein are for illustrative purposes only.

[0032] The embodiment of the present application provides a precious metal hammer bead forming machine, comprising:

[0033] abutment,

[0034] A lower pressing member is placed flat on the table surface of the base and extends upward along the first direction;

[0035] An upper pressing member, arranged opposite to the upper pressing member, located on a side of the lower pressing member away from the base, and extending downward along the first direction;

[0036] A material slot, wherein the material slot is recessed and formed on any one or both sides of the upper pressing part and the lower pressing part facing each other;

[0037] The stamping mechanism pushes the upper pressing part to be pressed together with the lower pressing part along the first direction. When viewed along the first direction, the material whose projection overlaps with the material groove is stamped by the upper pressing part and the lower pressing part into a product corresponding to the concave shape of the material groove.

[0038] The precious metal hammer bead forming machine provided above sets a material trough between the upper and lower pressing parts, and introduces a stamping mechanism to apply pressure to the upper pressing part so that the upper and lower pressing parts are pressed against each other. When the material enters the material trough, the stamping mechanism will stamp the material into a product with the same shape as the material trough, thereby automating the precious metal hammer forging.

[0039] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0040] See also Figure 1-Figure 5 An embodiment of the present application provides a precious metal hammer bead forming machine 100 , including a base 10 , a lower pressing part 20 , an upper pressing part 30 , a material trough 40 and a stamping mechanism 50 .

[0041] Among them, the lower pressing part 20 is placed flat on the table top of the base 10 and extends upward along the first direction 80; the upper pressing part 30 is arranged opposite to the upper pressing part 30, and is located on the side of the lower pressing part 20 away from the base 10, and extends downward along the first direction 80; the material groove 40 is recessed and formed on any one or both sides of the upper pressing part 30 and the lower pressing part 20; the stamping mechanism 50 pushes the upper pressing part 30 to be pressed together with the lower pressing part 20 along the first direction 80, and when observed along the first direction 80, the material whose projection overlaps with the material groove 40 is stamped by the upper pressing part 30 and the lower pressing part 20 into a product corresponding to the recessed shape of the material groove 40.

[0042] Specifically, the base 10 provides basic support and stability for the equipment. It ensures the stability and reliability of the equipment during operation and prevents vibration from interfering with the molding process. The lower pressing part 20 and the upper pressing part 30 constitute the pressing system of the molding machine, which is used to clamp and press the precious metal raw materials. Through the synergistic effect of these two parts, the stable clamping and precise molding of the raw materials are achieved, ensuring the accuracy and consistency of the products.

[0043] Furthermore, the material trough 40 provides a mold for forming the raw material, so that the formed precious metal can be stamped along a specific concave shape. The material trough 40 can be set to be only on one side of the upper pressing part 30, only on one side of the lower pressing part 20, or both the upper pressing part 30 and the lower pressing part 20. The design of the material trough 40 ensures that the formed product meets the expected shape, and improves the precision and consistency of the forming. The stamping mechanism 50 drives the upper pressing part 30 and the lower pressing part 20 to move relative to each other, realizes the stamping forming of the precious metal raw material, realizes an automated stamping process, improves production efficiency, and ensures high-quality forming of the product through precise control of the stamping mechanism 50.

[0044] Furthermore, the upper pressing part 30 and the lower pressing part 20 are in place on the base 10 and maintain a relatively stable position. The material trough 40 provides a mold of a specific shape, so that the precious metal raw material can be placed therein and prepared for molding. The stamping mechanism 50 is started, pushing the upper pressing part 30 to press with the lower pressing part 20 along the first direction 80, forming a stamping effect on the precious metal raw material. The concave shape of the material trough 40 ensures that the molded product is consistent with the expected shape. During the whole process, the design based on the above characteristics enables the equipment to automatically complete the molding process of the precious metal hammer beads, thereby improving production efficiency and product quality.

[0045] In a specific embodiment, the hammer bead forming machine also includes a feeding mechanism 60, which is arranged on the base 10. The feeding mechanism 60 includes a pushing component 61 and a rotating component 62. The pushing component 61 is placed flat on the table top of the base 10, and the rotating component 62 is arranged on the pushing component 61 to drive the material to rotate.

[0046] Specifically, the introduction of an automated feeding mechanism 60 is used to accurately feed the precious metal raw materials into the working area of ​​the hammer bead forming machine, thereby improving production efficiency, reducing manual operations, ensuring the accurate position of the raw materials, and facilitating the automation of the entire production process. The push assembly 61 is a key component of the feeding mechanism 60, and is placed flat on the table of the base 10 to feed the precious metal raw materials to the working area of ​​the hammer bead forming machine. The smooth movement of the push assembly 61 ensures the accurate positioning of the raw materials, and improves the accuracy and consistency of the forming.

[0047] Furthermore, the rotating assembly 62 is arranged on the pushing assembly 61, and is used to drive the precious metal raw material to rotate so that it is evenly stressed during the forming process. The design of the rotating assembly 62 ensures that the precious metal raw material is evenly stressed during the stamping process, improves the uniformity of the forming, and prevents deformation or irregular shapes.

[0048] Furthermore, the introduction of the rotating assembly 62 ensures that the precious metal raw material is uniformly stressed during the stamping process, making the cutting more complete. This helps to avoid incomplete or irregular cutting edges and improves the overall quality of the formed product. Through the action of the rotating assembly 62, the raw material can be better evenly distributed with force during the stamping process, thereby reducing the unevenness of the residual connection points or cuts. Since the cutting is more complete, the scrap rate of the product is relatively low. This helps to improve production efficiency and reduce the waste of resources caused by scrap. The integrity of the cutting is ensured by the rotating assembly 62, which helps to ensure the shape consistency of the formed product and meet the demand for high consistency of precious metal products.

[0049] In a specific embodiment, the pushing assembly 61 includes a housing 611, a feeding member 612 and

[0050] The cylinder 613 , the shell 611 is disposed on the base 10 , the feeding piece 612 is disposed in the shell 611 and penetrates the shell 611 , and the cylinder 613 is disposed in the shell 611 and abuts against the feeding piece 612 .

[0051] Specifically, the shell 611 is the external protection structure of the push assembly 61, which is fixed on the base 10, provides support and protection for other components, protects the internal components from interference from the external environment, and ensures the stability and life of the equipment. The feeder 612 is the core component of the push assembly 61. It passes through the shell 611 and is connected to the cylinder 613, and is responsible for pushing the precious metal raw materials into the working area of ​​the hammer bead forming machine. The cylinder 613 is the power source of the push assembly 61. By controlling the movement of the cylinder 613 to push the feeder 612, the automatic movement of the push assembly 61 is realized, the production efficiency is improved, and the need for manual operation is reduced.

[0052] In a specific embodiment, the feeding member 612 includes a telescopic portion 612a, a connecting portion 612b and a pushing portion 612c which are arranged in sequence, the pushing portion 612c is arranged on a side of the shell 611 close to the stamping mechanism 50, the telescopic portion 612a is arranged on a side away from the pushing portion 612c, and the output shaft of the cylinder 613 resists the pushing portion 612c.

[0053] Specifically, the telescopic portion 612a is a telescopic structure of the feeding member 612, which is used to adjust the length of the feeding member 612 and control the range of motion of the push assembly 61. The connecting portion 612b connects the telescopic portion 612a and the push portion 612c to ensure that the three parts work together to achieve a smooth feeding process. The push portion 612c is the end of the feeding member 612 and is responsible for feeding the precious metal raw material into the working area of ​​the stamping mechanism 50. Through the precise movement of the push portion 612c, the accurate position of the raw material is ensured, and the accuracy and consistency of the molding are improved.

[0054] Furthermore, the output shaft of the cylinder 613 is a moving part of the cylinder 613, which contacts the push part 612c and converts the movement of the cylinder 613 into the movement of the push part 612c. Through the movement of the output shaft, the cylinder 613 controls the drive of the push part 612c, thereby realizing the automatic movement of the entire feeding member 612.

[0055] In a specific embodiment, the rotating assembly 62 includes a gear 621 and a push rod 622 , the gear 621 is disposed on the housing 611 and fits the telescopic portion 612 a , the push rod supports the gear 621 , and the push rod 622 moves back and forth along the first direction 80 .

[0056] Specifically, the wheel is the core component of the rotating assembly 62, which is used to transmit power and motion. Through the design of the gear 621, an effective connection between the pushing assembly and the rotating assembly 62 is achieved, ensuring uniform force transmission during the pushing process. The pushing rod 622 connects the gear 621 and the pushing assembly 61, and is responsible for pushing the precious metal raw material to rotate under the action of the gear 621. Through the design of the pushing rod 622, precise control of the precious metal raw material is achieved, ensuring the stability and consistency of the rotational motion.

[0057] Furthermore, when the push rod 622 starts to move back and forth, the gear 621 also starts to rotate because it abuts against the gear 621. Since the gear 621 is in contact with the telescopic portion 612a, the rotation of the gear 621 drives the movement of the telescopic portion 612a. Through the synergistic effect of the telescopic portion 612a and the connecting portion 612b, the push assembly moves back and forth along the first direction 80, thereby realizing the rotation of the precious metal raw material.

[0058] In a specific embodiment, it is defined that when the push rod 622 is extended, it is a first state 622a, and when the push rod 622 is retracted, it is a second state 622b:

[0059] When in the first state 622a, the push rod 622 pushes the gear 621 to rotate, driving the feeding mechanism 60 to rotate, thereby driving the material to rotate;

[0060] When in the second state 622 b , after the push rod 622 is retracted, the gear 621 is stationary, and the stamping mechanism 50 pushes the upper pressing member 30 to press the lower pressing member 20 .

[0061] Specifically, in the first state 622a, the push rod 622 is pushed out and connected to the gear 621, so that the gear 621 starts to rotate. The movement of the gear 621 is realized by pushing out the push rod 622, driving the rotation of the feeding mechanism 60, thereby driving the precious metal raw material to rotate. In the second state 622b, the push rod 622 is retracted and separated from the gear 621, so that the gear 621 is stationary, and the stamping mechanism 50 starts to move. After the push rod 622 is retracted, the gear 621 stops rotating, and the stamping mechanism 50 pushes the upper pressing part 30 to press the lower pressing part 20, completing the stamping forming of the precious metal raw material.

[0062] In a specific embodiment, an elastic member 614 is disposed on the telescopic portion 612 a , and the elastic member 614 is sleeved on the telescopic portion 612 a to restore the pushing assembly 61 to an initial state.

[0063] Specifically, the presence of the elastic member 614 makes the telescopic portion 612a have a certain elasticity, which can be deformed during the pushing process and then quickly return to the initial state. Such a design ensures that when the pushing component 61 is moving, the telescopic portion 612a can adapt to different degrees of deformation and quickly return to the initial state after the pushing is completed, ensuring a continuous and stable production process. The elastic member 614 is sleeved on the telescopic portion 612a, encapsulating the telescopic portion 612a so that it can be evenly stressed and protecting the elastic structure of the telescopic portion 612a. By sleeve-mounting the elastic member 614, it is ensured that the external force on the telescopic portion 612a is evenly distributed.

[0064] Furthermore, when the push assembly 61 is working, the telescopic portion 612a is deformed due to the external force, and the elastic member 614 is compressed or stretched. After the push assembly 61 is finished moving, the external force is reduced or disappears, and the elastic member 614 quickly acts, so that the telescopic portion 612a quickly returns to its initial state. This process ensures that the push assembly 61 can quickly return to the ready state after each production cycle to carry out the next round of production.

[0065] In a specific embodiment, the pushing assembly 61 further includes a limiting member 63 , and the limiting member 63 is disposed above the pushing portion 612 c and is used to limit the pushing distance of the pushing portion 612 c .

[0066] Specifically, the limiter 63 is located above the push portion 612c, and is mainly used to limit the push distance of the push portion 612c to ensure the accuracy and consistency of the push. Through the existence of the limiter 63, the movement range of the push portion 612c can be controlled to prevent excessive or insufficient pushing, and ensure that the precious metal raw materials pushed each time can reach the predetermined position. When the push assembly 61 starts to move, the push portion 612c pushes as the push rod 622 extends. The movement of the push portion 612c is carried out within a certain distance. When the push portion 612c reaches the limit position set by the limiter 63, the limiter 63 takes effect. The limiter 63 will apply resistance to the push portion 612c or stop the movement of the push portion 612c to ensure that the push portion 612c does not exceed the specified range. After the push assembly 61 completes its work, the push rod 622 retracts, and the push portion 612c returns to the initial position to prepare for the next push.

[0067] In a specific embodiment, the limiting member 63 is threadedly connected to the housing 611 .

[0068] Specifically, the limiter 63 is connected to the housing 611 by a thread, so that the limiter 63 can be fixed on the housing 611 to ensure that it will not loosen or fall off by itself. Through the threaded connection, the position of the limiter 63 can be easily adjusted and fixed, which improves the maintainability and stability of the system. By rotating the limiter 63, its threaded part matches the thread of the housing 611. The limiter 63 rotates counterclockwise or clockwise so that its thread is tightly combined with the thread of the housing 611. Through rotation adjustment, the relative position of the limiter 63 and the housing 611 can be changed, thereby adjusting the limit range of the push assembly 61. When the desired limit position is reached, the limiter 63 is fastened to the housing 611 to keep the relative position unchanged.

[0069] In a specific embodiment, an elastic block 70 is disposed between the upper pressing member 30 and the lower pressing member 20 .

[0070] Specifically, the presence of the elastic block 70 between the upper pressing part 30 and the lower pressing part 20 plays a role in buffering and absorbing impact force, so that the precious metal raw materials of different shapes and sizes can be adapted during the stamping process. Through the design of the elastic block 70, the collision of the upper and lower pressing parts 20 during the stamping process can be slowed down, the impact force can be reduced, the integrity of the precious metal raw materials can be protected, and the molding accuracy of the product can be improved.

[0071] Furthermore, when the stamping mechanism 50 pushes the upper pressing part 30 to apply pressure to the lower pressing part 20, the elastic block 70 is compressed. The compression of the elastic block 70 absorbs the impact force when the upper and lower pressing parts 20 collide, and plays a buffering role. When the stamping process is completed and the upper pressing part 30 and the lower pressing part 20 are separated, the elastic block 70 quickly returns to its original state to prepare for the next stamping process.

[0072] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
