Description

Technical Field

[0001] This utility model relates to the field of chain production technology, specifically to a ring pressing and guiding device for a circular ring chain. Background Technology

[0002] Circular link chains, as a common chain structure, are widely used in decoration, mechanical transmission, and connection applications. They are made from a variety of materials, such as stainless steel, carbon steel, and brass, with the appropriate material chosen based on specific needs in different applications. The manufacturing process of circular link chains involves pressing short bars of equal length into rings using a stamping machine, then nesting and connecting these rings to form a continuous chain structure. Subsequent processes include ring pressing and welding to ensure the chain's strength and integrity.

[0003] However, in the current production situation, some small workshops still use manual production methods. Taking the ring pressing process as an example, workers need to frequently flip the chain rings and perform stamping and shaping operations. Because this process is manual, the workers' fingers are in frequent and close contact with the stamping machine punch, and if the operation is not careful, it can easily cause serious personal injury accidents. This manual operation method not only poses safety hazards, but also has low production efficiency. Utility Model Content

[0004] This invention provides a guide device for pressing rings in a circular chain, which solves the problems of safety hazards and low production efficiency of manual ring pressing mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A circular chain pressure ring guiding device is provided with a guide seat, which has a square shape. The top of the guide seat is provided with a positioning horizontal groove and a positioning vertical groove. Both ends of the positioning horizontal groove are provided with V-shaped flares. Multiple auxiliary support blocks are provided inside the positioning vertical groove, and each auxiliary support block is provided with a rotating shaft.

[0007] Preferably, a left sliding groove and a right sliding groove are respectively provided at both ends of the positioning longitudinal groove, and an auxiliary support block is provided in both the left sliding groove and the right sliding groove.

[0008] Preferably, a left support is provided in the left slide groove, the left support is configured as a U-shaped frame structure, and a plurality of auxiliary support blocks are provided in the left support, with the rotating shaft of each auxiliary support block being installed on the left support.

[0009] Preferably, a right support is provided in the right slide groove, the right support is configured as a U-shaped frame structure, and multiple auxiliary support blocks are provided in the right support, with the rotating shaft of each auxiliary support block installed on the right support.

[0010] Preferably, the auxiliary support block is configured as a cylindrical structure, and a recessed contact surface is provided in the middle of the auxiliary support block.

[0011] Preferably, the left support is elastically installed in the left slide groove, and the right support is elastically installed in the right slide groove.

[0012] Preferably, a left support spring is provided in the left slide groove, one end of which is connected to the inner wall of the left slide groove, and the other end of which is connected to the outer wall of the left support. A right support spring is provided in the right slide groove, one end of which is connected to the inner wall of the right slide groove, and the other end of which is connected to the outer wall of the right support.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0014] 1. The circular chain pressing guide device described in this utility model, by setting a guide seat, positioning horizontal groove, positioning vertical groove, auxiliary support block and other structures, allows workers not to directly contact the punch of the punching machine during the circular chain pressing process. They only need to place the circular chain on the guide seat and pull it at both ends of the guide seat to complete the pressing operation. This effectively avoids the safety hazards caused by contact between fingers and punch and greatly improves the safety of the production process.

[0015] 2. The circular link chain pressing ring guiding device described in this utility model can accurately position and stably support the chain, making the pressing ring operation more standardized and efficient. Compared with manual frequent flipping of the chain rings for stamping and shaping, using this device can reduce operation steps, shorten production time, and thus improve overall production efficiency.

[0016] 3. The circular ring chain pressure ring guiding device described in this utility model has a cylindrical shape and recessed contact surface design for the auxiliary support block, which can better fit circular ring chains of different specifications. In addition, the flexible installation method of the left and right supports allows the device to automatically adjust the support position according to the actual situation of the chain, which enhances the adaptability of the device to different chains and improves the versatility of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, a circular link chain pressing ring guiding device includes a guide seat 1, which has a square shape. The top of the guide seat 1 has a positioning transverse groove 2 and a positioning longitudinal groove 3. Both ends of the positioning transverse groove 2 have V-shaped flares. Multiple auxiliary support blocks 5 are arranged inside the positioning longitudinal groove 3, and each auxiliary support block 5 has a rotating shaft 6 inside. Furthermore, each end of the positioning longitudinal groove 3 has a left sliding groove 7 and a right sliding groove 8, and each of the left and right sliding grooves 7 and 8 contains an auxiliary support block 5. This design facilitates the positioning of the circular link chain by the auxiliary support blocks 5, allowing the circular link chain to move stably within the sliding grooves and providing better support for the chain. This allows the operator's fingers to stay away from the punch of the stamping machine and the dangerous operating area; the stamping and shaping operation can be achieved by pulling the circular link chain at both ends of the guide seat 1. Because the auxiliary support block 5 supports the lower part of the circular chain in the positioning groove 3, the stability of the circular chain can be maintained during stamping and forming, which solves the drawback of the traditional method of requiring operators to hold the circular chain at close range to stabilize it, and improves the safety of production.

[0023] Furthermore, a left support 9 is provided in the left slide groove 7. The left support 9 is a U-shaped frame structure, and multiple auxiliary support blocks 5 are provided in the left support 9. The rotating shaft 6 of each auxiliary support block 5 is mounted on the left support 9. The U-shaped frame structure of the left support 9 provides a stable mounting base for the auxiliary support blocks 5, ensuring the stability of the auxiliary support blocks 5 during operation. At the same time, the multiple auxiliary support blocks 5 work together to better support the circular link chain.

[0024] Similarly, a right support 10 is provided in the right slide groove 8. The right support 10 is a U-shaped frame structure, and multiple auxiliary support blocks 5 are provided in the right support 10. The rotating shaft 6 of each auxiliary support block 5 is installed on the right support 10. The right support 10 and the left support 9 cooperate with each other to provide all-round support for the circular link chain, ensuring the stability of the circular link chain during the pressing process.

[0025] In terms of structural design, the auxiliary support block 5 is set as a cylindrical structure with a recessed contact surface 11 in the middle. The cylindrical shape of the auxiliary support block 5 facilitates installation and rotation, and the recessed contact surface 11 can better fit the shape of the circular chain, increase the contact area with the circular chain, improve the support effect on the circular chain, and prevent the circular chain from shifting during the pressing process.

[0026] To enable the device to better adapt to different states of the circular chain, the left support 9 is elastically installed in the left slide groove 7, and the right support 10 is elastically installed in the right slide groove 8. This elastic installation allows the left and right supports 10 to automatically adjust their positions according to the shape and stress of the circular chain, enhancing the adaptability and stability of the device.

[0027] Specifically, a left support spring 12 is installed in the left slide groove 7, with one end connected to the inner wall of the left slide groove 7 and the other end connected to the outer wall of the left support 9. A right support spring 13 is installed in the right slide groove 8, with one end connected to the inner wall of the right slide groove 8 and the other end connected to the outer wall of the right support 10. The left and right support springs 13 provide elastic support forces to the left and right supports 10 respectively, enabling the left and right supports 10 to move flexibly when subjected to the force of the chain, and to return to their original positions after the force disappears, ensuring the normal operation of the device.

[0028] Working principle: When using the circular chain pressing guide device provided by this utility model, the circular chain to be pressed is first placed on the positioning groove 2 of the guide seat 1. The V-shaped flared openings 4 at both ends of the positioning groove 2 can easily guide the circular chain into the positioning groove 2, playing a preliminary positioning role.

[0029] After the circular chain is placed, part of the circular chain will be above the positioning groove 3. At this time, the auxiliary support block 5 inside the positioning groove 3 begins to function. The auxiliary support block 5 is installed on the left support 9 and the right support 10, which are located in the left slide groove 7 and the right slide groove 8 respectively, and are elastically installed through the left support spring 12 and the right support spring 13.

[0030] When the circular chain is placed on the auxiliary support block 5, the recessed contact surface 11 in the middle of the auxiliary support block 5 will fit tightly against the circular chain, providing stable support for the circular chain. Since the auxiliary support block 5 has a rotating shaft 6 inside and is installed on the left and right supports 10, the auxiliary support block 5 can rotate with the movement of the circular chain during placement and movement, reducing friction between the circular chain and the auxiliary support block 5 and ensuring the smoothness of the circular chain during the pressing process.

[0031] During the ring pressing operation, the punch of the stamping machine is aligned with the part of the circular link chain to be pressed, and the stamping machine is started to perform the ring pressing operation. During this process, the guide seat 1 can accurately position the circular link chain, preventing it from shifting during the stamping process. Simultaneously, the elastic mounting structure of the left and right supports 10 allows the auxiliary support block 5 to automatically adjust its position according to the force applied to the circular link chain, always maintaining stable support and ensuring the smooth progress of the ring pressing operation.

[0032] After completing the ring pressing operation, remove the pressed circular chain to begin the next round of ring pressing.

[0033] In summary, the circular link chain pressing guide device provided by this utility model effectively solves the safety hazards and low production efficiency problems associated with manual pressing through its unique structural design. In practical applications, it provides a safer and more efficient operating method for the production of circular link chains. Specifically, when pulling the circular link chain for stamping and shaping, the operator can pull at both ends of the guide seat 1, avoiding the drawbacks of traditional methods that require close-range hand-holding to stabilize the circular link chain for stable stamping and shaping. This device has promising application prospects.
