Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a riveting mold with multiple buffering effects. Background Art

[0002] The riveting die is a key tool used in the riveting process. Its main function is to use external force to connect or overlap the participating parts in a certain order and manner to form a whole. Riveting dies are widely used in aerospace, automobile manufacturing, construction engineering, electronic equipment and other fields, especially in occasions requiring high-precision connections and lightweight structures. Riveting dies have the characteristics of high precision, high efficiency, and high reliability, and can meet the requirements of different industries for connection quality and production efficiency. Compared with traditional connection methods, the riveting process has the advantages of fast connection speed, simple operation, and no thermal deformation. It is particularly suitable for materials that are easily affected by heat, such as aluminum alloys.

[0003] Some existing riveting dies are not equipped with corresponding buffer structures when in use. The dies are prone to direct collision when closing the dies, which will generate large impact force and noise, especially when closing quickly or positioning inaccurately, which may aggravate the wear of the dies and even damage the dies.

[0004] For example, a riveting mold with an anti-drifting function disclosed in announcement number CN218503145U is convenient for operators to disassemble and replace the anti-drifting function, the limiter function and the limiter function with less effort through the anti-drifting function, the auxiliary function, the limiter function, the riveting mold 2 and the limiter function. At the same time, the anti-drifting function, the pressure limiter function, the limiter function and the limiter function can also effectively prevent the device from drifting during use through the anti-drifting function, the pressure limiter function, the limiter function and the limiter function, thereby ensuring the quality of the product.

[0005] The patented riveting die has been carefully designed to prevent deviation, including anti-drift components, limit components, and multiple adjustment mechanisms. However, the die has obvious deficiencies in reducing collisions between dies, namely, the lack of a buffer structure. When riveting die 2 is closed with riveting die 1, the two are in direct contact, and no buffer structure of any kind is provided. This direct closing method may cause greater impact force and noise between the dies, especially when closing quickly or positioning is inaccurate, which may aggravate the wear of the dies and even damage the dies.

[0006] Therefore, it is necessary to invent a riveting die with multiple buffering effects to solve the above problems. Utility Model Content

[0038] Working principle of this utility model:

[0039] Refer to the instruction manual Figure 1-5When using the utility model, firstly, the workpiece to be riveted is accurately placed in the riveting groove 21 of the lower module 13 to ensure that the position of the workpiece is correct;

[0040] Before starting the riveting operation, start the infrared transmitter 26 and the infrared receiver 27 to put them in working state. The infrared transmitter 26 will emit infrared rays downward, and the infrared receiver 27 will continuously monitor and receive these infrared signals. When the infrared signal is transmitted normally, it means that there is no obstacle on the workbench 1 and the operation can be carried out safely. If the transmission of the infrared signal is blocked, it means that an object appears on the workbench 1 at this time. The infrared receiver 27 will immediately detect this change. Once the infrared receiver 27 detects that the infrared signal is blocked, it will send a signal to the control panel 28. After receiving the signal, the control panel 28 will immediately suspend the entire riveting operation process to prevent possible Accidents: After the operation is suspended, the operator needs to check whether there are any obstacles on the workbench 1 and remove them. This step is very critical because it ensures that the transmission of infrared signals can be restored. When the obstacles are removed and the infrared transmission is restored, the infrared receiver 27 will receive stable infrared signals again. At this time, the control panel 28 will detect this change and allow the operator to restart the riveting operation. During the entire riveting operation, the infrared transmitter 26 and the infrared receiver 27 will continue to work and continuously monitor whether there are any obstacles on the workbench 1. This continuous monitoring mechanism ensures the safety of the operation and effectively avoids accidents when the operator is using the mold.

[0041] The control panel 28 controls the No. 1 electric push rod 22 to start working, pushing the upper mold carrier plate 5 to move downward along the guide rod 11. During this process, the No. 2 spring 12 begins to be compressed and contracted, providing the first buffer for the descent of the mold;

[0042] As the upper mold assembly 3 continues to descend, the upper mold block 7 comes into contact with the No. 1 rubber pad 17 on the top of the lower mold block 13. At this time, the No. 1 rubber pad 17 plays a buffering role, avoiding a direct collision between the upper mold block 7 and the lower mold block 13.

[0043] When the upper module 7 continues to descend, the telescopic rod 6 begins to shrink, and at the same time, the outer spring No. 1 8 also begins to shrink, providing a second buffering effect, further reducing the impact force during mold closing;

[0044] During the mold closing process, the positioning pile 9 at the bottom of the upper module 7 is gradually inserted into the positioning hole 14 at the top of the lower module 13. As the positioning pile 9 is inserted, the damper 15 in the positioning hole 14 begins to be compressed and gradually shrinks, providing a third buffer for the mold closing, further reducing the impact force and noise during mold closing;

[0045] When the riveting protrusion 20 at the bottom of the upper module 7 is fully matched with the riveting groove 21 of the lower module 13, the riveting of the workpiece is completed;

[0046] The No. 1 electric push rod 22 is controlled by the control panel 28 to work in reverse, and the upper mold assembly 3 is lifted to the initial position. Then, the No. 2 electric push rod 24 is controlled by the control panel 28 to start working, pushing the push plate 25 to move upward, thereby pushing the riveted workpiece out of the riveting groove 21 to facilitate the unloading operation.
