Description

Technical Field

[0001] This utility model relates to the field of gold and jewelry processing technology, specifically to a forging device for gold and jewelry materials. Background Technology

[0002] Gold jewelry refers to jewelry made primarily of gold. Gold is a bright, reddish-yellow metal that is soft, dense, and malleable. It is one of the rarest, most precious, and highly valued metals. In the process of making gold bracelets, forging blocks of gold into long strips of a specific size is an important preliminary step. Due to the softness of gold, traditional forging devices have many problems.

[0003] An existing patent (publication number: CN213195463U) discloses a material forging device for gold jewelry production, including a forging furnace. An installation plate is fixedly installed inside the forging furnace. A first motor is fixedly installed on the top outer surface of the installation plate. The output shaft of the first motor extends to the bottom of the installation plate via a coupling and is fixedly connected to a rotating shaft. An annular sliding groove is formed inside the installation plate. Two sets of sliding blocks are slidably installed inside the annular sliding groove. A rotating disk is fixedly installed on the adjacent sidewalls of the two sets of sliding blocks. The top outer surface of the rotating disk is fixedly connected to one end of the rotating shaft. A high-temperature torch is fixedly installed on the bottom outer surface of the rotating disk. A lifting mechanism is provided inside the forging furnace. A support platform is fixedly installed on the bottom outer surface of the forging furnace. A forging platform is fixedly installed on the top outer surface of the support platform. Two sets of forging grooves are formed on the forging platform and are centrally symmetrical.

[0004] Although the aforementioned patent saves time by calcining gold jewelry on one side and forging it on the other, thus avoiding the need to repeatedly shut off the heat source and switch forging methods, it has certain drawbacks. It directly forges the gold raw material, and lacks flexible positioning and clamping during forging, which can lead to errors and substandard dimensions. Furthermore, the clamping position needs to be constantly changed to adapt to different forging stages when forging gold from blocks to bars. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a forging device for gold and jewelry materials, which has the advantage of flexibly positioning and clamping raw materials during the forging process, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gold jewelry material forging device, comprising a frame and a worktable mounted on the upper surface of the frame, wherein the upper surface of the worktable is provided with a positioning component for positioning raw materials and a forging component for forging raw materials; The positioning component includes two transverse moving slots mounted on the upper surface of the worktable. A transverse moving block is slidably connected to the inner wall of each transverse moving slot. A longitudinal moving slot is located above the transverse moving slots, with both ends connected to the transverse moving blocks. A longitudinal moving block is slidably connected to the inner wall of the longitudinal moving slot. A fixing seat is fixed to the side of each longitudinal moving block. A clamping cylinder is mounted on the outer side of the fixing seat. An elastic chuck is mounted at the output end of the clamping cylinder. The elastic chuck is made of polytetrafluoroethylene (PTFE), which is soft and heat-resistant, allowing it to firmly clamp the gold block without scratching the gold surface. A pressure sensor is installed inside the elastic chuck, which monitors the clamping force in real time and feeds the signal back to the control system. By adjusting the clamping force of the clamping cylinder, excessive clamping force can be prevented from deforming the gold. The pressure sensor is connected to an external control device.

[0007] Furthermore, the forging assembly includes a lifting plate, a forging cylinder is mounted on the upper surface of the lifting plate, and a forging hammer is mounted on the output end of the forging cylinder.

[0008] The above scheme uses a forging cylinder to drive a forging hammer to reciprocate forging the gold raw material. The forging cylinder is controlled by a pneumatic proportional valve, and the forging force can be precisely adjusted by the control system to avoid excessive force that could damage the gold.

[0009] Furthermore, the forging assembly also includes a hydraulic lifting rod installed on the upper surface of the workbench, the other end of which is connected to the lifting plate. A plug is fixed on the upper surface of the workbench, and the plug passes through the lifting plate.

[0010] The above solution uses a hydraulic lifting rod to move the forging cylinder and forging hammer head up and down, meeting the forging needs of gold blocks of different thicknesses.

[0011] Furthermore, a heating assembly is provided inside the fixing base. The heating assembly includes two mounting plates disposed inside the fixing base. Multiple vertically arranged resistance heating plates are mounted on one side of the two mounting plates that are close to each other. An adjusting cylinder is mounted on the outer side of the fixing base, and the output end of the adjusting cylinder is connected to its corresponding mounting plate.

[0012] With the above solution, the multiple resistance heating plates installed on the inner side of the mounting plate adopt zoned heating, which can select the heating area according to the size of the gold block, avoiding energy waste. The heating components heat the gold raw material from both sides, reducing the hardness of the gold, reducing work hardening, and facilitating forging and shaping.

[0013] Furthermore, a temperature sensor is installed on the inner top wall of the fixing base, and the temperature sensor is located above the resistance heating plate.

[0014] The above scheme uses a temperature sensor to monitor the temperature of the gold material at the heating position of the resistance heating plate and feeds the temperature signal back to the control system. When the temperature exceeds the set range, the external control device controls the resistance heating plate to stop heating, preventing the gold from melting due to excessive temperature and affecting the forging operation.

[0015] Furthermore, a lateral adjustment motor is installed at the end of the lateral moving slot on the left side, and a lateral adjustment threaded rod is installed at the output end of the lateral adjustment motor. The lateral adjustment threaded rod is threadedly connected to the lateral moving block.

[0016] The above scheme allows the lateral adjustment motor to drive the lateral adjustment threaded rod to rotate, thereby moving the lateral moving block.

[0017] Furthermore, a longitudinal adjustment motor is installed at the end of the longitudinal moving groove, and a longitudinal adjustment threaded rod is installed at the output end of the longitudinal adjustment motor. The longitudinal adjustment threaded rod is threadedly connected to the longitudinal moving block.

[0018] The above scheme enables the longitudinal adjustment motor to drive the longitudinal adjustment threaded rod to rotate, thereby moving the longitudinal moving block.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This gold jewelry forging device, through the setting of a positioning component, clamps the gold raw material with an elastic chuck driven by a clamping cylinder before forging. A pressure sensor can monitor the clamping force in real time and feed the signal back to the control system. By changing the clamping force of the clamping cylinder, it prevents excessive clamping force from deforming the gold while ensuring the stability of the gold raw material during forging. A temperature sensor monitors the heating of the gold raw material. When the gold raw material is heated to a suitable temperature, it is immediately transferred to the forging area for forging, reducing work hardening and facilitating the forging and shaping of the gold raw material.

By changing the clamping force of the clamping cylinder 304, the system can prevent the gold from deforming due to excessive clamping force. The pressure sensor 306 is connected to the signal of an external control device.

[0024] Please see Figure 1 , Figure 2 and Figure 3The forging assembly 4 includes a lifting plate 401, on the upper surface of which a forging cylinder 402 is mounted. A forging hammer 403 is mounted at the output end of the forging cylinder 402. The forging cylinder 402 drives the forging hammer 403 to reciprocate forging the gold raw material. The forging cylinder 402 is controlled by a pneumatic proportional valve, and the forging force can be precisely adjusted by the control system to avoid excessive force that could damage the gold. The forging assembly 4 also includes a hydraulic lifting rod 404 mounted on the upper surface of the workbench 2. The other end of the hydraulic lifting rod 404 is connected to the lifting plate 401. An insert rod 405 is fixed on the upper surface of the workbench 2 and passes through the lifting plate 401. The hydraulic lifting rod 404 can drive the forging cylinder 402 and the forging hammer 403 to move up and down, meeting the forging requirements of gold blocks of different thicknesses.

[0025] Please see Figure 2 , Figure 3 and Figure 4 The fixing base 303 is equipped with a heating component 5. The heating component 5 includes two mounting plates 501 disposed inside the fixing base 303. Multiple resistance heating plates 502 arranged vertically are mounted on the side of the two mounting plates 501 that are close to each other. An adjusting cylinder 503 is mounted on the outer side of the fixing base 303. The output end of the adjusting cylinder 503 is connected to its corresponding mounting plate 501. The multiple resistance heating plates 502 mounted on the inner side of the mounting plate 501 adopt zone heating, which can select the heating area according to the size of the block of gold, avoiding energy waste. The heating component 5 heats the gold raw material from both sides, reducing the hardness of the gold, reducing work hardening, and facilitating forging and shaping.

[0026] Please see Figure 2 , Figure 3 and Figure 4 A temperature sensor 504 is installed on the inner top wall of the fixed base 303. The temperature sensor 504 is located above the resistance heating plate 502. The temperature sensor 504 monitors the temperature of the gold raw material at the heating position of the resistance heating plate 502 and feeds the temperature signal back to the control system. When the temperature exceeds the set range, the external control device controls the resistance heating plate 502 to stop heating to prevent the gold from melting due to excessive temperature and affecting the forging operation.

[0027] Please see Figure 1 , Figure 2 and Figure 4A horizontal adjustment motor 307 is installed at the end of the horizontal moving slot 301 on the left side. A horizontal adjustment threaded rod 308 is installed at the output end of the horizontal adjustment motor 307.

The vertical adjustment threaded rod 310 is threadedly connected to the vertical moving block. The vertical adjustment motor 309 can drive the vertical adjustment threaded rod 310 to rotate, thereby driving the vertical moving block to move.

[0028] It should be noted that before the operation begins, the threshold values ​​of the pressure sensor 306 and the temperature sensor 504 need to be input into the external control device. During the operation, the external controller will adjust the clamping force of the elastic chuck 305 based on the information fed back by the pressure sensor 306, ensuring that the gold material is kept stable during the forging process without being damaged. At the same time, the controller will control the heating time and temperature of the heating component 5 based on the information fed back by the temperature sensor 504, and coordinate with the positioning component 3 to transfer the gold material heated to the appropriate temperature to the position of the forging component 4 in a timely manner.

[0029] The working principle of the above embodiment is as follows: When in use, the block of gold is placed under the fixed base 303. The threshold values ​​of the pressure sensor 306 and the temperature sensor 504 are input into the external control device. The horizontal adjustment motor 307 and the vertical adjustment motor 309 drive the vertical moving groove 302 and the fixed base 303 to move. The fixed base 303 moves above the block of gold. The adjusting cylinder 503 drives the mounting plate 501 to approach the block of gold. The resistance heating plate 502 heats the gold material. During the heating process, the temperature sensor 504 monitors the temperature of the gold material in real time and feeds the temperature signal back to the control system. When the temperature exceeds the set range, the external control device controls the resistance heating plate 502 to stop heating to prevent the gold from melting due to excessive temperature and affecting the forging operation.

[0030] After the heating process is completed, the fixed base 303 moves, driving the clamping cylinder 304 to move. The clamping cylinder 304 drives the elastic chuck 305 to clamp the block of gold and move the gold material to the bottom of the forging component 4. During the clamping process, the pressure sensor 306 can monitor the clamping force in real time and feed the signal back to the control system. The external control device changes the clamping force of the clamping cylinder 304 to prevent the gold from deforming due to excessive clamping force.

[0031] The hydraulic lifting rod 404 drives the lifting plate 401 to descend, the lifting plate 401 drives the forging cylinder 402 to descend, and the forging cylinder 402 drives the forging hammer 403 to forge the heated gold material. During the forging process, the positioning component 3 moves and adjusts the gold material continuously, and feeds the material continuously during the movement and adjustment process, sending the heated gold material to the forging hammer 403 for forging. After the forging is completed, the material is flipped 90 degrees and put back in for forging. The operation is repeated many times until the final shape is formed.
