Description

Technical Field

[0001] The present application relates to the field of jewelry processing, and in particular to a jewelry chain machine. Background Art

[0002] In jewelry processing, there will be scenes where necklaces and other jewelry need to be processed. The most traditional processing method is for the processing master to manually bend the rope-shaped metal material into a ring, and then splice the rings together. This processing method is very time-consuming and labor-intensive, so jewelry chain machines used to process jewelry came into being.

[0003] Traditional jewelry chain machines rely on a specific dividing mechanism to divide rope-shaped metal materials into equal small segments, and then the forming mechanism bends the small segments of metal materials into ring-shaped chain links. The position of the chain links is adjusted by the grabbing arm so that the metal material can pass through the chain links, so that the metal material is connected to the previous chain link while forming the chain link to form a complete jewelry chain. In the production process, in order to make the gap at the connection between the two ends of the chain link invisible and to make the chain link more stable, it is often necessary to weld the contact points at both ends of the chain link to form a complete ring. However, burn marks will be left during the welding process, and the shape will become irregular during the metal melting process, affecting the beauty of the entire jewelry chain.

[0004] Therefore, it is necessary to propose a jewelry chain machine that can reduce the gap between the two ends of the chain link without welding the chain link to solve the problem that the traditional jewelry chain machine connects the chain link by welding, which affects the appearance.

[0032] An embodiment of the present application provides a jewelry chain machine, comprising:

[0033] abutment;

[0034] A rotating mold table, the rotating mold table is rotatably connected to the base, the jewelry material is placed on the rotating mold table, the rotating mold table has a boss, and the jewelry material is located outside the boss;

[0035] A forming mechanism, the forming mechanism is arranged on the base, and the forming mechanism squeezes the jewelry material until the jewelry material adheres to the side surface of the boss to form a chain link;

[0036] The extrusion mechanism is arranged opposite to the rotating die table, and the extrusion mechanism extrudes the chain ring so that the two ends of the chain ring are closely fitted.

[0037] The jewelry chain machine provided above is designed with an extrusion mechanism. After the chain link is formed, the contact positions at both ends of the chain link are squeezed by the extrusion mechanism to make the two ends of the chain link fit tightly, thereby reducing the gap between the two ends of the chain link, solving the problem that the traditional jewelry chain machine connects the chain links by welding, which affects the appearance.

[0038] 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.

[0039] See also Figure 1-Figure 7 The embodiment of the present application provides a jewelry chain machine 100, including a base 1, a rotating mold table 2, a molding mechanism 3 and an extrusion mechanism 4, wherein the rotating mold table 2 is rotatably connected to the base 1, and the jewelry material is placed on the rotating mold table 2, and the rotating mold table 2 has a boss 21, and the jewelry material is located on the outer side of the boss 21. The molding mechanism 3 is arranged on the base 1, and the molding mechanism 3 squeezes the jewelry material until the jewelry material fits on the side of the boss 21 to form a chain link, which is arranged opposite to the rotating mold table 2. The extrusion mechanism 4 squeezes the chain link so that the two ends of the chain link fit tightly.

[0040] Specifically, the rotating mold table 2 is used to support the jewelry material and rotate it during the processing. The boss 21 on the rotating mold table 2 is one of the molds used for molding the jewelry material. The jewelry material is squeezed between the boss 21 and the molding mechanism 3. Finally, the jewelry material is deformed to form a chain link with an inner contour similar to the outer contour of the boss 21. The shape of the chain link can be changed by changing the outer contour shape of the boss 21, which provides convenience for processing jewelry of different shapes. The rotating mold table 2, as the name implies, can rotate around the base 1. The role of the rotation is to drive the chain link to rotate. By rotating the chain link while the molding mechanism 3 does not rotate, various parts of the chain link can be squeezed. , so that the chain links with more complex shapes can be processed. The characteristic of the forming mechanism 3 is that it is a device that can slide on the base 1, and uses a motor as a power source. Usually, multiple forming mechanisms 3 are arranged around the rotating mold table 2. When the jewelry material needs to be extruded, the forming mechanism 3 moves toward the rotating mold table 2 under the push of the power source and then extrudes the jewelry material on the rotating mold table 2. Multiple forming mechanisms 3 usually need to extrude the jewelry material in sequence, and extrude the jewelry material into chain links step by step like origami. This is usually achieved by controlling the starting sequence of the motor. The extrusion mechanism 4 is used to make the two ends of the chain link fit tightly to ensure the integrity and firmness of the chain link. This helps to prevent the chain link from breaking or cracking during use. The difference between the extrusion mechanism 4 and the forming mechanism 3 is that the shape of the extrusion mechanism 4 is more delicate. The forming mechanism 3 makes the chain link have a preliminary deformation, while the function of the extrusion mechanism 4 is to use the more precise mold on the extrusion mechanism 4 to shape the connection of the chain link, so that the connection of the chain link looks natural and smooth.

[0041] In a specific example, the extrusion mechanism 4 includes a transmission member 41 disposed on the base 1 and an extrusion member 42 drivingly connected to the transmission member 41 , and an extrusion groove 4211 is provided on the extrusion member 42 , and the chain ring is located in the extrusion groove 4211 for extrusion.

[0042] Specifically, the transmission member 41 is located on the base 1 and is usually driven by a motor. It is the power source of the extrusion mechanism 4 and is responsible for transmitting power to the extrusion member 42. The extrusion member 42 is connected to the transmission member 41 by transmission and is located below the transmission member 41. It is a key component in the extrusion mechanism 4 and is responsible for the actual extrusion operation. An extrusion groove 4211 is provided on the extrusion member 42, and its function is to accommodate the chain link and apply extrusion force. The shape and size of the extrusion groove 4211 should match the desired chain link shape to ensure the quality and shape of the chain link after extrusion. At the same time, changing the shape of the extrusion groove 4211 can also change the shape of the chain link connection to a certain extent. The extrusion groove 4211 can be adjusted from the perspective of appearance requirements. The chain link is placed in the extrusion groove 4211, and then the extrusion member 42 applies pressure to extrude the chain link into the desired shape. The existence of the extrusion groove 4211 ensures the accuracy and stability of the extrusion operation.

[0043] In a specific example, an extrusion head 421 is provided on the extrusion piece 42 , the extrusion groove 4211 is located on the extrusion head 421 , and the extrusion head 421 is detachably connected to the extrusion piece 42 .

[0044] Specifically, the extrusion head 421 is a part of the extrusion member 42 and is usually located at the top thereof. Its main function is to apply pressure to the extrusion groove 4211 to extrude the jewelry material. The extrusion head 421 usually has a specific shape and size to adapt to the extrusion grooves 4211 and jewelry materials of different shapes and sizes. Its design should take into account the uniform distribution of the extrusion force to ensure that the jewelry material is evenly extruded during the extrusion process to form a chain link that meets the requirements. The detachable connection design between the extrusion head 421 and the extrusion member 42 helps to maintain and replace the extrusion head 421 to adapt to different processing requirements or repair damaged parts. The connection between the extrusion head 421 and the extrusion member 42 usually adopts a threaded connection or other detachable connection method to facilitate disassembly and replacement. This design allows maintenance personnel to easily replace the extrusion head 421 with a model suitable for a specific processing task and clean and maintain it when necessary.

[0045] In a specific example, it also includes a first motor 5 arranged on the base 1 and a grabbing arm 6 that is transmission-connected to the first motor 5 , the first motor 5 is screw-connected to the grabbing arm 6 , and the first motor 5 pushes the grabbing arm 6 to move along the length direction of the grabbing arm 6 .

[0046] Specifically, the grabbing arm 6 plays a coordinating role in the production of the jewelry chain. The grabbing arm 6 grabs the formed chain link and moves it away from the rotating mold table 2 to facilitate the jewelry material to enter the rotating mold table 2 to produce the next chain link.

[0047] Further, first, the first motor 5 is started, and its rotation drives the screw rod to rotate, so that the grabbing arm 6 moves along its length direction. When the grabbing arm 6 reaches the target position, the motor stops rotating, and the grabbing arm 6 grabs the jewelry material. Then, the motor is started again, and the grabbing arm 6 moves the jewelry material to the next processing step or the removal machine.

[0048] In a specific example, a positioning gear 61 is provided on the grabbing arm 6, a sliding groove 11 is provided on the base 1, a positioning rack 13 is slidably connected to the sliding groove 11, the positioning gear 61 and the positioning rack 13 are transmission connected, a cylinder 15 is provided at one end of the sliding groove 11, the cylinder 15 pushes the positioning rack 13 to slide in the sliding groove 11, and drives the positioning gear 61 to rotate.

[0049] Specifically, the function of the positioning rack 13 is to drive the grabbing arm 6 to rotate through the transmission connection with the positioning gear 61. The rotation of the grabbing arm 6 plays an auxiliary role in connecting the chain links in the chain production. After the grabbing arm 6 grabs the chain link, the chain link can be rotated by rotating the grabbing arm 6, so that the chain link on the grabbing arm 6 and the chain link to be formed on the rotating mold table 2 form an angle difference, so that the two chain links can fit each other. When the two ends of the chain link on the rotating mold table 2 are not fitted together, the grabbing arm 6, driven by the first motor 5, inserts the rotated chain link into the unformed chain link, and then the forming mechanism 3 extrude the chain link to a preliminary forming to form a chain.

[0050] Furthermore, in the present design, the extrusion mechanism 4 squeezes the chain link grasped on the grabbing arm 6 to make the two ends of the chain link fit tightly. The specific steps are that the cylinder 15 drives the grabbing arm 6 to rotate through the positioning rack 13, thereby driving the chain link on the grabbing arm 6 to rotate. When the chain link rotates to the angle to be processed, the grabbing arm 6 drives the chain link to the movement path of the extrusion mechanism 4 under the drive of the motor. The extrusion member 42 receives the chain link into the extrusion groove 4211 for extrusion under the push of the transmission member 41. The advantage of designing the molding mechanism 3 and the extrusion mechanism 4 separately is to make full use of the space on the base 1.

[0051] In a specific example, an adjusting screw 12 is disposed on the sliding slot 11 . The adjusting screw 12 is located at an end away from the cylinder 15 , and the adjusting screw 12 extends into the sliding slot 11 .

[0052] Specifically, the function of the adjusting screw 12 is to limit the moving range of the positioning clip. After the adjusting screw 12 is inserted into the sliding groove 11, it is on the moving path of the positioning clip. During the sliding process of the positioning clip, it will contact the adjusting screw 12 and be blocked by the adjusting screw 12. The adjusting screw 12 thus achieves the effect of limiting the movement of the positioning clip. The moving distance of the positioning clip in the sliding groove 11 is adjusted by changing the depth of the adjusting screw 12 screwed into the sliding groove 11. The advantage of doing so is that the rotation of the positioning gear 61 is indirectly controlled. When the positioning clip stops moving, the positioning gear 61 will also stop moving. By changing the depth of the adjusting screw 12 inserted into the sliding groove 11, the rotation range of the grabbing arm 6 is controlled, thereby controlling the rotation range of the chain ring, so as to facilitate processing.

[0053] In a specific example, it further comprises a material dividing mechanism 7, wherein the material dividing mechanism 7 divides the jewelry material into shapes suitable for processing.

[0054] Specifically, the material dividing mechanism 7 is used to divide the raw jewelry material into suitable shapes and sizes for processing. The material dividing mechanism 7 is usually composed of a series of mechanical devices, including a cutter, a cutting plate, a guide device, etc., and its design purpose is to ensure that the raw material is divided according to the predetermined shape and size. First, the operator places the raw jewelry material in the feeding area of ​​the material dividing mechanism 7, and these raw materials are provided in the form of strips. The material dividing mechanism 7 usually includes positioning and guiding devices, whose function is to ensure that the raw material can be accurately positioned and guided during the dividing process. These devices usually consist of clamps, positioning pins, guide plates, etc., which can ensure that the position and direction of the raw material are accurate. Once the raw material is accurately positioned and guided, the dividing mechanism starts to operate. This usually includes a cutter or a cutting plate, whose function is to cut the raw material into a suitable shape and size. The cutter may be a rotating blade, a knife die or a knife wheel, etc., which cuts the raw material through corresponding movements. The cutting plate is fixed on the material dividing mechanism 7, and the raw material interacts with the blade through movement to achieve the purpose of cutting.

[0055] In a specific example, it further includes a transport mechanism 8 disposed on the base 1, the transport mechanism 8 transports the jewelry material to the rotating mold table 2, the transport mechanism 8 has a molding wheel 81, and the molding wheel 81 squeezes the jewelry material to shape the jewelry material.

[0056] Specifically, the transport mechanism 8 is a device for transporting jewelry materials from the feeding area to the rotating mold table 2 for subsequent processing. The material dividing mechanism 7 is located between the transport mechanism 8 and the rotating mold table 2 to cut the jewelry materials. The forming wheel 81 is an important component on the transport mechanism 8. Its function is to apply pressure to the jewelry materials during transportation to shape them. The forming wheel 81 usually has a certain pressure and shape, which can ensure that uniform pressure is applied to the jewelry materials to form the desired shape. Since jewelry materials are generally in the form of strips, the strip materials are easy to bend during transportation, and the forming wheel 81 is required to readjust the strip jewelry materials to be straight. The transport mechanism 8 is usually composed of a transmission device, a conveyor belt or a roller, etc., and its design is to achieve stable and accurate movement of jewelry materials from one position to another.

[0057] In a specific example, a transport pipe 9 is provided on the base 1 , and the processed chain links flow out of the outside through the transport pipe 9 .

[0058] Specifically, the transport tube 9 is a device for outputting the processed chain links from the working area of ​​the jewelry chain machine 100 to the outside. The transport tube 9 is usually a pipe or a conduit, and its design ensures that the chain links can flow smoothly from the inside of the machine to the outside, while preventing the chain links from being stuck or blocked. The processed chain will fall directly into the transport tube 9 and be discharged to the outside through the transport tube 9. This is because the opening of the transport tube 9 is directly set below the rotating mold table 2, and the opening is directly opposite to the position where the chain links are spliced. The spliced ​​chain links will fall into the transport tube 9 and be discharged to the outside.

[0059] In a specific example, the molding mechanism 3 includes a second motor 31 disposed on the base 1 and a top block 32 connected to the second motor 31 by a lead screw. A slide rail 14 is disposed on the base 1 , and the top block 32 is slidably connected to the slide rail 14 .

[0060] Specifically, the molding mechanism 3 is a device for molding jewelry materials, and its function is to process the jewelry materials into the shape of a chain link. The second motor 31 is the power source of the molding mechanism 3, and is used to drive the moving parts in the molding process. It is usually located on the base 1. The rotation direction and speed of the second motor 31 can be adjusted by the control system to achieve precise control of the molding process. The top block 32 is one of the moving parts of the molding mechanism 3, which is connected to the second motor 31 through a lead screw and is responsible for processing the jewelry material. The top block 32 is usually made of rigid material and can withstand the extrusion force during the molding process. The slide rail 14 is a guide device fixed on the base 1, and its function is to guide and support the movement of the top block 32. The slide rail 14 usually has a smooth surface and a precise manufacturing process to ensure that the top block 32 can move stably during the molding process. First, the processed jewelry material is sent to the processing area of ​​the molding mechanism 3. That is, the rotating mold table 2, and then the second motor 31 is started to drive the top block 32 to move along the slide rail 14 to process the jewelry material into the desired chain link shape. During the forming process, the top block 32 applies appropriate pressure to shape the jewelry material. Finally, after the forming is completed, the processed chain link is sent to subsequent processing steps or output.

[0061] 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.
