Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments in this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application. Example

[0025] like Figure 1-4 As shown, this embodiment illustrates a gold jewelry stamping mechanism, comprising a worktable 1, a reciprocating drive mechanism, a mold mechanism, a stamping mechanism, a steel stamping die 12, and a controller 2. The reciprocating drive mechanism is mounted on the worktable 1; the mold mechanism is connected to the reciprocating drive mechanism and is equipped with a pressure sensor 10; the stamping mechanism is suspended above the worktable 1; the steel stamping die 12 is connected to the stamping mechanism; and the controller 2 is electrically connected to the reciprocating drive mechanism, the stamping mechanism, and the pressure sensor 10. The stamping mechanism drives the steel stamping die 12 to be inserted into the mold mechanism.

[0026] The die mechanism is used to hold the block-shaped gold jewelry that needs to be extruded and shaped.

[0027] The reciprocating drive mechanism provides the power source for the movement of the mold mechanism. The reciprocating drive mechanism drives the mold mechanism to move directly below the steel stamp mold, which facilitates the insertion of the steel stamp mold into the mold mechanism when it moves down.

[0028] The stamping mechanism serves as the power source for the movement of the stamping die. It drives the die to move vertically. When the die needs to be inserted into the mold mechanism, the stamping mechanism drives it downwards. Once the die has completed the stamping process, the stamping mechanism moves it upwards to reset and disengage from the mold mechanism. This allows the reciprocating drive mechanism to move the mold mechanism away from below the die, facilitating the removal of the block of gold jewelry from within the mold mechanism.

[0029] It should be noted that the controller has an upper limit on the pressure. When the stamping die drives the steel stamping die to extrude the block of gold jewelry and the movable template, the pressure sensor monitors the extrusion force in real time and transmits the monitored data to the controller. When the monitored pressure reaches the set upper limit, the controller controls the impact mechanism to stop extruding the steel stamping die downwards and moves the steel stamping die upwards to reset.

[0030] One structure of a reciprocating drive mechanism is given, such as Figure 1 , 2 As shown, the reciprocating drive mechanism includes a guide rod 6, a lead screw 21, a threaded guide sleeve 22, a sliding sleeve 7, a slide table 8, and a lead screw drive motor 19. The lead screw 21 and the guide rod 6 are arranged parallel to each other at intervals; the threaded guide sleeve 22 is installed on the lead screw 21 and threadedly connected to the lead screw 21; the sliding sleeve 7 is sleeved on the guide rod 6; one end of the slide table 8 is connected to the threaded guide sleeve 22, and the other end is connected to the sliding sleeve 7, which is used to support the mold mounting mechanism; the lead screw drive motor 19 is connected to the lead screw 21 for transmission.

[0031] One type of screw mounting structure: one end of the screw 21 is rotatably connected to the first bearing seat 3, and the other end passes through the second bearing seat 20 and is connected to the screw drive motor 19 for transmission.

[0032] One type of guide rod installation structure: The two ends of the guide rod 6 are mounted on the worktable 1 via support bases 4.

[0033] To ensure accurate positioning, a first limit sensor 5 and a second limit sensor 26 are installed. The first limit sensor 5 and the second limit sensor 26 are installed at intervals on the guide rod 6, and both the first limit sensor 5 and the second limit sensor 26 are electrically connected to the controller 2.

[0034] The sliding sleeve 7 moves along the guide rod. When the sliding sleeve 7 touches the second limit sensor 26, it stops moving. At this time, the slide table moves the mold mechanism directly below the steel stamp mold. When the sliding sleeve 7 touches the first limit sensor 22, it stops moving. At this time, the slide table moves the mold mechanism away from directly below the steel stamp mold, which makes it easier to remove the block gold jewelry from the mold mechanism.

[0035] One structure of the mold mechanism is given, such as Figure 1 , 3 As shown in Figure 4, the mold mechanism includes a stamping die 9, a storage cylinder 23, a spring 24, and a movable template 11. The stamping die 9 has a storage groove 93 with an open top, which is used to store and install the pressure sensor 10. A first through hole 94 is opened at the bottom. The storage cylinder 23 is installed at the bottom of the first through hole 94. One end of the spring 24 passes through the pressure sensor 10, inserts into the storage cylinder 23 through the first through hole 94, and the other end protrudes from the top surface of the pressure sensor 10. A fixed shaft 25 is installed at the bottom of the movable template 11. The fixed shaft 25 is inserted into the spring 24 and extends into the storage cylinder 23.

[0036] like Figure 3 , 4 As shown, the stamping die 9 has a first die opening 91 at one end and a second die opening 92 at the other end. The first die opening 91 and the second die opening 92 allow the movable template to expose the storage groove, which facilitates workers to place and remove block-shaped gold jewelry from the movable template.

[0037] It should be noted that when the device is idle, the spring 24 supports the movable template above the pressure sensor 10, which makes it easy to place the block gold jewelry on the movable template. Similarly, it also makes it easy to remove the engraved block gold jewelry from the movable template.

[0038] The fixed axis 25 penetrates the pressure sensor 10 and is inserted into the storage cylinder 23, which facilitates the restriction of the position of the movable template. When the movable template is subjected to a downward squeezing force, the fixed axis and the storage cylinder cooperate to guide the movable template to move downward.

[0039] like Figure 4 As shown, the pressure sensor 10 is provided with a second through hole 101, through which the spring can pass through the pressure sensor.

[0040] Understandably, one end of spring 24 is connected to the storage cylinder, and the other end is connected to the fixed shaft. While the stamped die compresses the block gold jewelry, the movable template 11, and the fixed shaft 25 towards the bottom of the storage groove 93, the compression spring 24 undergoes elastic deformation, possessing elastic potential energy. It compresses until the movable template adheres to the pressure sensor. The pressure sensor monitors the compressive force in real time. When the monitored pressure exceeds the set upper limit, the stamping mechanism drives the stamped die to move upwards and reset. Spring 24 then pushes the movable template upwards and resets, disengaging the movable template from the pressure sensor. The movable template protrudes above the bottom of the storage groove, facilitating the removal of the block gold jewelry from the movable template.

[0041] It should be noted that the bottom of the storage tube is spaced apart from the top surface of the worktable, so the storage tube will not touch the worktable when it moves. The storage tube is used to store the fixed shaft and spring.

[0042] To facilitate the placement and removal of block gold jewelry, the movable template 11 has U-shaped grooves 111 at both ends. The U-shaped grooves at both ends allow fingers to be inserted easily, enabling quick handling of the block gold jewelry and allowing for rapid placement and removal of the block gold jewelry from the movable template.

[0043] In some optional embodiments, an installation structure for the stamping mechanism is provided, which includes a support frame 18, a suspension rod 181, and a clamp 16. One end of the support frame 18 is mounted on the worktable 1, and the other end is provided with a suspension rod 181 that is spaced parallel to the worktable 1. The clamp 16 is mounted on the suspension rod 181 and is used to support the stamping mechanism.

[0044] In some alternative embodiments, one structure of the stamping mechanism is provided. The stamping mechanism includes a telescopic drive 17, a chuck 14, and a connecting shaft 13. The telescopic drive 17 is provided with a telescopic rod 15; the chuck 14 is mounted on the telescopic rod 15; one end of the connecting shaft 13 is clamped and connected to the chuck 14, and the other end is connected to the stamping die 12.

[0045] It should be noted that the chuck is a commonly used clamping tool. The chuck is connected to the connecting shaft, which facilitates the detachable installation of the connecting shaft.

[0046] The telescopic drive component can be a pneumatic cylinder or a hydraulic cylinder.

[0047] According to the above embodiments, the working principle of this utility model is as follows:

[0048] By controlling the lead screw drive motor 19 to drive the lead screw 21 to rotate, the lead screw 21 drives the threaded guide sleeve 22 to move towards the first bearing seat 3. At the same time, the threaded guide sleeve 22 drives the slide table 8 and the slide sleeve 7 to move. The slide table 8 drives the mold mechanism to move towards the front end of the worktable 1. When the slide sleeve 7 touches the first limit sensor 5, the controller controls the lead screw drive motor 19 to stop working.

[0049] The staff can then place the block of gold jewelry on the movable template 11, and then control the screw drive motor 19 to drive the screw 21 to rotate in the opposite direction through the controller. While the screw 21 drives the threaded guide sleeve 22 to move toward the screw drive motor 19, the slide table 8 and the slide sleeve 7 move with the threaded guide sleeve 22. When the slide sleeve 7 touches the second limit sensor 26, the controller 2 controls the screw drive motor 19 to stop working, and the screw 21 stops rotating. At this time, the stamping die 9 and the movable template 11 are located directly below the stamping die 12.

[0050] Controller 2 controls the telescopic drive component 17 to operate. The telescopic drive component 17 drives the telescopic rod 15 to extend downward, causing the stamping mold 12 to move towards the movable template 11. The stamping mold 12 extrudes the block-shaped gold jewelry and moves the movable template 11 downward. The movable template moves the fixed shaft 25 downward while simultaneously compressing the spring 24. When the movable template 11 moves downward and comes into contact with the pressure sensor 10, the spring 24 is compressed and stored in the storage cylinder 23. The pressure sensor 10 monitors the pressure in real time and transmits the data to the controller. When the pressure reaches the set upper limit value, the controller controls the telescopic drive component 17 to extend and retract. When rod 15 retracts upwards to reset, telescopic drive component 17 drives the telescopic rod upwards for 3-6 seconds. At this time, the steel stamping mold 12 disengages from the stamping mold 9. Simultaneously, controller 2 controls lead screw drive motor 19 to work, which drives lead screw 21 to rotate. Lead screw 21 drives threaded guide sleeve 22 to move towards the front end of the worktable. When sliding sleeve 7 touches the first limit sensor 5, controller controls lead screw drive motor 19 to stop working, and slide table 8 and stamping mold 9 stop moving. The block-shaped gold ornament engraved by the steel stamping mold can then be taken out, completing the engraving of the block-shaped gold ornament and enhancing its aesthetics.

[0051] It should be noted that when the stamping die 12 moves upward, the spring 24 pushes the movable template 11 upward for elastic reset. The spring pushes the movable template away from the pressure sensor. The spring can support the movable template at the middle of the stamping die height direction, which facilitates the removal of the block-shaped gold ornaments on the movable template through the first die opening and the second die opening.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
