Description

Technical Field

[0001] This utility model relates to the technical field of gold jewelry processing equipment, and in particular to a quick pressing and forming device for gold chain links. Background Technology

[0002] Gold links are the basic units that make up gold necklaces and bracelets. Their processing and manufacturing include multiple processes such as pressing, fastening, and shaping. In the fastening and shaping process of the links, a special fastening and shaping device is used to apply pressure to the links through a mold to make them close and take shape.

[0003] Because gold chain links on the market come in a variety of styles, sizes, and shapes, it is necessary to frequently change the matching clamping claws when producing chain links of different specifications. However, existing clamping forming devices use bolts to fix the clamping claws, and the replacement process requires the use of wrenches for disassembly and assembly. This is not only cumbersome and time-consuming, but frequent disassembly and assembly can also easily lead to wear and tear on the connecting parts, thereby affecting the overall production efficiency and equipment stability.

[0004] In addition, when processing gold as a precious metal, some small fragments are inevitably generated. These gold fragments are valuable, but due to their small size and light weight, they are easily splashed and scattered throughout the equipment and even on the ground during processing due to mechanical vibrations. They are difficult to collect effectively, which not only wastes valuable raw materials and increases production costs, but also makes subsequent cleaning and recycling work very tedious.

[0005] Therefore, this utility model proposes a rapid pressing and forming device for gold chain knots to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of cumbersome and time-consuming operation of changing the pressing claws and low efficiency in the existing gold link quick pressing and forming device, as well as the easy loss of gold fragments generated during the pressing and forming process, resulting in material waste, this utility model aims to provide a gold link quick pressing and forming device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a quick snap-fit ​​forming device for gold chain links, including: a support frame, a drive rod, a mounting plate, a mounting column, and a pressure claw; as well as a recycling mechanism.

[0008] The recycling mechanism is fixed to the support frame and is used to collect the debris generated during the pressing and forming process of the pressure claw.

[0009] Preferably, the recycling mechanism includes a collection chamber, a negative pressure fan, a flexible tube, and a suction nozzle; the negative pressure fan is located inside the collection chamber, the flexible tube is connected to the collection chamber, the suction nozzle is connected to the end of the flexible tube, and the suction port of the suction nozzle faces the working area of ​​the pressure claw.

[0010] Preferably, the collection chamber is further provided with a support plate for installing the negative pressure fan, and a filter screen located on the air intake side of the negative pressure fan.

[0011] Preferably, the wall of the collection chamber is also provided with a metering window for observing the amount of debris inside and a discharge port for removing the debris.

[0012] Preferably, the mounting plate is provided with a mounting groove, and the mounting column is detachably connected to the mounting plate by snap-fitting into the mounting groove.

[0013] Preferably, the buckle is extended by the elastic force of the second spring to lock the mounting post.

[0014] Preferably, the device further includes a pressing block, a wedge rod linked to the pressing block, and a connecting rod; one end of the connecting rod contacts the inclined surface of the wedge rod, and the other end is linked to the buckle; the movement of the wedge rod drives the buckle to retract inward through the connecting rod to release the locking of the mounting post.

[0015] Preferably, the mounting post is further provided with a first spring for providing a restoring force to the wedge rod.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problems of cumbersome operation, long time consumption, and low efficiency when changing different specifications of pressure claws in the prior art by setting up the linkage of pressing block, wedge rod, connecting rod and buckle. It achieves the purpose of quick disassembly and replacement of pressure claws by hand, which significantly improves the flexibility of equipment use and production efficiency.

[0017] 2. This utility model solves the problem of gold fragments easily splashing and scattering during the pressing and forming process of gold chain links, resulting in the waste of precious metal raw materials, by setting up a recycling mechanism consisting of a negative pressure fan, a collection chamber, a flexible tube, and a suction nozzle. It achieves precise collection and recycling of gold fragments at the source, effectively avoids raw material loss, and improves economic efficiency. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figures 1 to 4 This utility model provides a quick pressing and forming device for gold chain links, which aims to solve the problems of easy loss of raw materials caused by the loss of debris during the processing of gold chain links and low efficiency in changing the mold of pressing claw 1 in the prior art.

[0022] like Figure 1 and Figure 2 As shown, the gold chain link quick snap-fit ​​forming device includes a support frame 12 as a mounting base, and a snap-fit ​​forming assembly that can slide up and down on the support frame 12. The snap-fit ​​forming assembly includes a drive rod 11, a mounting plate 10 fixedly connected to the lower end of the drive rod 11, a mounting post 3 detachably mounted on the mounting plate 10, and a pressing claw 1 fixed to the end of the mounting post 3. The pressing claw 1 is used to perform snap-fit ​​forming on the gold chain link. The device also includes a recycling mechanism 2 fixed to the support frame 12, which is used to collect the debris generated during the snap-fit ​​forming process in a timely manner.

[0023] To solve the above-mentioned technical problems, the technical solution of this embodiment is to provide a recycling mechanism 2 for immediate collection of debris, and to design a quick replacement mechanism in the mounting structure of the pressure claw 1.

[0024] Please refer to Figure 2 and Figure 4 The structure of recycling mechanism 2 will be described in detail below: The recycling mechanism 2 includes a collection chamber 201, a negative pressure fan 205 located inside the collection chamber 201 to generate negative pressure suction, a flexible tube 202 connected at one end to the collection chamber 201, and a suction nozzle 203 connected to the other end of the flexible tube 202. The suction nozzle 203 is preferably a flexible structure, and its suction port is precisely oriented towards the working area of ​​the pressing claw 1 when in use. This structural design allows the suction generated by the negative pressure fan 205 to efficiently suck the gold debris generated by the pressing claw 1 during pressing and cutting of raw materials into the collection chamber 201 through the flexible tube 202 and the suction nozzle 203, thus avoiding the loss of precious metal raw materials.

[0025] Please refer to Figure 3 and Figure 4 The quick-change mechanism for pressure claw 1 will be described in detail below: The mounting plate 10 has a mounting groove, and the mounting post 3 is detachably installed in the mounting groove through a quick-release locking structure. The quick-release locking structure includes a buckle 8 for directly engaging the mounting post 3, a connecting rod 7 for driving the buckle 8, a wedge rod 5 that is driven by the connecting rod 7, and a pressing block 4 that is fixedly connected to the wedge rod 5. When the pressure claw 1 needs to be replaced, pressing the pressing block 4 moves the wedge rod 5, and the inclined surface of the wedge rod 5 pushes the connecting rod 7, thereby driving the buckle 8 to retract inward and release the lock on the mounting post 3, thus realizing the quick disassembly and replacement of the mounting post 3 together with the pressure claw 1. This linkage mechanism composed of the pressing block 4, the wedge rod 5, the connecting rod 7 and the buckle 8 greatly simplifies the replacement operation and improves production efficiency.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to provide a stable installation foundation for the negative pressure fan 205 and optimize the internal structure of the collection chamber 201, please refer to... Figure 4 A support plate 204 is fixedly connected to the inner wall of the collection chamber 201, and the negative pressure fan 205 is fixedly installed on the support plate 204 by bolts. In order to prevent the sucked-in debris from damaging the negative pressure fan 205, a filter screen 206 is also fixed inside the collection chamber 201 and located on the suction side of the negative pressure fan 205. The filter screen 206 is used to intercept gold debris.

[0027] As another preferred embodiment, in order to facilitate operators to monitor the amount of debris recovered and clean it up in a timely manner, a metering window 207 is also provided on the side wall of the collection bin 201. Operators can intuitively observe the accumulation of debris inside through the metering window 207. At the same time, a discharge port 208 is provided at the bottom of the collection bin 201. When the amount of debris reaches a certain level, the discharge port 208 can be opened to remove and recycle the debris.

[0028] For further optimization of the quick-change mechanism, please refer to... Figure 3 To achieve automatic locking of the buckle 8, a second spring 9 is fitted around the outer periphery of the buckle 8. The elastic force of the second spring 9 continuously pushes the buckle 8 toward the extended position. Once the mounting post 3 is inserted into place, the buckle 8 automatically pops out and securely locks itself in place.

[0029] As a further optimization of the quick-change mechanism, in order to ensure that the pressing block 4 and the wedge rod 5 can automatically reset after operation, a first spring 6 is provided in the internal cavity of the mounting post 3. One end of the first spring 6 abuts against the wedge rod 5, and the other end abuts against the inner wall of the mounting post 3, so as to provide the elastic force for the wedge rod 5 to reset.

[0030] Working principle: During installation, the mounting post 3 can be inserted into the mounting groove on the inner wall of the mounting plate 10. The buckle 8 extends and firmly locks in place under the elastic action of the second spring 9, completing the fixed installation. The support frame 12 provides stable support for the drive rod 11. The drive rod 11 drives the mounting plate 10 connected at the bottom to move down, completing the snap-fit ​​operation. When changing different pressure claws 1 to meet the snap-fit ​​requirements of different sizes, press the pressing block 4 to move the wedge rod 5 on the rear side backward. The first spring 6 can provide the wedge rod 5 with the elastic force to reset, ready for the start of the next operation. Then, through the inclined plane characteristics, the connecting rod 7 drives the buckle 8 to continuously retract inward, releasing the buckle 8 from the locking of the mounting plate 10, completing the replacement of pressure claws 1 of different specifications. After the recycling mechanism 2 is started, the negative pressure fan 205 generates negative pressure suction, which is transmitted to the suction nozzle 203 through the flexible tube 202. The suction nozzle 203 with adjustable curved tube can accurately target the area where debris is generated when the chain links are pressed and formed and the gold raw materials are cut, sucking the debris into the collection chamber 201. The support plate 204 fixed to the inner wall of the collection chamber 201 provides the installation base for the negative pressure fan 205, while the filter screen 206 fixed to the inner wall of the collection chamber 201 can intercept debris and prevent debris from entering the negative pressure fan 205 and causing damage. The operator can observe the amount of debris stored in the collection chamber 201 through the metering window 207. When the amount of debris raw materials reaches a certain amount, the discharge port 208 can be opened to take out the gold debris collected in the collection chamber 201 for recycling, completing one recycling process.
