[0002] A riveting machine (also known as a riveting machine, a rotary riveting machine, a riveting machine, a rolling riveting machine, etc.) is a new type of riveting equipment developed based on the principle of cold rolling. It refers to a mechanical equipment that can rivet objects together with rivets. During the riveting process, by applying pressure to the rivet, one end of the rivet forms an expanded shape inside the workpiece, thereby firmly connecting the components together. This connection method has the advantages of high reliability, easy operation and cost-effectiveness, so it is widely used.

[0003] However, conventional riveting machines have some obvious limitations in operation. For example, they can usually only assemble rivets of one specification, and every time the rivet specification is changed, the current die needs to be manually removed and replaced with a new one. This process is not only time-consuming and labor-intensive, but also prone to equipment damage or reduced work efficiency due to improper operation.

[0004] In addition, on high-speed production lines, the need to frequently change molds has greatly reduced the continuity and flexibility of production and seriously affected work efficiency, which is a considerable challenge for the modern manufacturing industry that pursues high efficiency and diversified production.

[0005] Therefore, it is necessary to further improve and perfect the prior art to overcome these deficiencies, and the present invention is made based on this situation. Utility Model Content

[0006] The utility model aims to overcome the deficiencies of the prior art and provide a quick die-changing tooling for a riveting machine which has a simple structure, is easy to operate and can conveniently and quickly replace the die.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Aiming at the low efficiency problem of replacing dies of traditional riveting machines, the utility model aims to create a quick die-changing tooling that can simplify the replacement process and shorten the replacement time.

[0025] like Figures 1 to 4The quick die-changing tooling for a riveting machine shown in the figure comprises a base 1 installed on the riveting machine and located below the riveting head, and a rotating base 2 that can rotate horizontally is rotatably connected to the base 1. The rotating base 2 is provided with a plurality of dies 3 arranged around its rotation center, and these dies are designed to have different specifications and shapes according to work requirements to adapt to different riveting tasks.

[0026] A locking structure 4 is installed between the rotating seat 2 and the base 1. Its function is to ensure that the rotating seat 2 can be firmly locked in the appropriate position when the mold 3 is aligned with the rivet head, to prevent displacement during the riveting process, and to ensure the riveting quality. The design of the locking structure 4 not only ensures the stability of the rotating seat, but also keeps the entire mold change process simple and fast.

[0027] The tooling is compact in design and realizes the function of rapid mold replacement, which greatly improves production efficiency and equipment adaptability. It is especially suitable for occasions where molds need to be replaced frequently to meet different production requirements.

[0028] The tooling has a simple structure, low cost, and is very easy to operate. During operation, the user only needs to simply unlock the locking structure 4 and then manually rotate the rotating seat 2 until the required mold 3 is located directly below the riveting head. After the mold alignment is completed, the rotating seat 2 is locked again by the locking structure 4, and the mold replacement is completed.

[0029] Such a design will allow operators to quickly change different molds without using additional tools or performing tedious operations, thereby improving mold change efficiency, greatly simplifying the operating steps, and reducing the difficulty of operation, thereby effectively shortening downtime and improving the flexibility and response speed of the production line.

[0030] In detail, the locking structure 4 is mainly composed of three core components: a fixed block 41, a latch 42 and an elastic reset member 43. That is, the locking structure 4 includes a fixed block 41 fixed on the base 1, and a latch 42 is slidably connected to the fixed block 41 in the up and down directions. The latch 42 is a key component in the locking structure, which is responsible for directly locking or unlocking the rotating seat 2. Its design needs to allow it to switch freely between different positioning holes 21 while ensuring stability in the locked position. Each positioning hole 21 corresponds to a mold 3, ensuring that the mold 3 can accurately align the rivet head.

[0031] An elastic reset member 43 is provided between the latch 42 and the fixed block 41 to elastically press the latch 42 upward. The elastic reset member 43, which is usually a spring, is an important component to ensure that the latch 42 can be automatically reset. The lower surface of the rotating seat 2 is provided with a plurality of positioning holes 21 for the latch 42 to be inserted from bottom to top. The latch 42 is a key component to achieve the locking function. It can switch between different positioning holes 21 and ensure the accurate positioning of the rotating seat 2 when changing molds. When the latch 42 is inserted into different positioning holes 21, the different corresponding molds 3 are aligned just below the rivet head.

[0032] When the mold needs to be replaced, the operator only needs to manually press the latch 42 downward to compress the spring to disengage from the current positioning hole 21, and then manually rotate the rotating seat 2 to the position where the desired mold 3 is aligned with the rivet head. After releasing the latch 42, the spring automatically pushes the latch upward until it is inserted into the newly aligned positioning hole 21, achieving fast and stable locking.

[0033] This unlocking and locking process is not only simple and easy, but also greatly reduces the time and labor intensity required for mold change, improving work efficiency. Through this design, operators can quickly and accurately change molds to meet different production needs, while ensuring the stability of the production process and riveting quality.

[0034] It is worth noting that the design of the locking structure 4 is not limited to the latch structure described above, but may include other mechanisms with similar functions to achieve a quick and stable connection and release between the rotating seat 2 and the base 1. For example, these alternative locking structures may include but are not limited to:

[0035] 1) Wedge-locking mechanism: This mechanism may involve a wedge-shaped block that can slide along the fixed block and enter the wedge-shaped groove under the rotating seat, which can be locked by hammering or manual pressure. To release, the wedge block can be pried up or pulled back to release the lock.

[0036] 2) Quick clamping device: For example, a quick release lever similar to a bicycle seat tube can be used to clamp or release the swivel seat by flipping the lever, which is simple and quick to operate.

[0037] 3) Magnetic locking: A locking structure that uses magnetic force to maintain the rotating seat in the correct position, and releases the connection by applying external force to overcome the magnetic attraction. It is suitable for occasions where frequent mold changes are required.

[0038] 4) Locking pin and swivel nut combination: The locking pin can be inserted into the positioning hole, and the swivel nut can be screwed into the threaded hole on the fixed block to fix the locking pin. Quick locking and unlocking can be achieved by releasing and tightening the swivel nut.

[0039] 5) Pneumatic or hydraulic actuators: These automated locking structures use pneumatic or hydraulic force to drive a locking device, which can be remotely controlled and is suitable for production environments with a high degree of automation.

[0040] 6) Snap-on connector: Similar to the snap-on connectors used on some electronic devices, this design allows the swivel to lock with a simple push action and unlock with a push-to-release mechanism.

[0041] 7) Screw clamp: By rotating a knob or handle, the clamp is screwed in or out to lock and unlock the swivel seat.

[0042] The choice of these locking structures will depend on the specific application requirements, including the required locking strength, ease of operation, cost, reliability and ease of maintenance. When designing, it should also be considered whether these locking mechanisms are compatible with the existing riveting machine system and whether they can improve production efficiency and operator comfort.

[0043] More specifically, the mold 3 and the rotating seat 2 are detachably connected and a first detachable connection structure is provided between the two. The detachable connection design between the mold 3 and the rotating seat 2 not only improves the applicability and flexibility of the riveting machine, but also greatly increases the production efficiency of the machine and the convenience of mold replacement. The limited installation positions designed for the rotating seat 2 means that the utilization and functionality of each installation position must be maximized without expanding the size of the machine. By introducing the first detachable connection structure, each installation position can be used with different molds 3, which not only expands the scope of application of the riveting machine, but also provides users with more operating options and flexibility.

[0044] Specifically, the first detachable connection structure is mainly composed of the mounting hole 22 on the upper surface of the rotating seat 2 and the plug connector 31 at the lower end of the mold 3. This design allows the mold 3 to be easily inserted into the mounting hole 22 on the rotating seat 2 through the plug connector 31 at its lower end to achieve quick connection. In order to ensure the stability of the connection and the fixity of the mold during use, the side of the rotating seat 2 is designed with a threaded hole 23 at the position corresponding to each mounting hole 22. By installing the first fastener 5 in the threaded hole 23, the plug connector 31 can be tightened to ensure the stability of the mold 3 during operation.

[0045] The first fastener 5 is preferably a screw or a jackscrew. The design of the first fastener 5 takes into account both the stability of the connection and the convenience of disassembly. The operator can tighten or loosen the first fastener 5 with simple tools, such as a screwdriver or a wrench, to complete the rapid replacement of the mold 3. This design not only reduces the time required for mold replacement, but also greatly reduces the complexity of the operation and improves production efficiency.

[0046] In addition, the design of the first detachable connection structure also takes into account durability and reliability in long-term use. The size, shape and material selection of the mounting hole 22 and the plug connector 31, as well as the strength design of the threaded hole 23 and the first fastener 5, are all required to ensure that the connection structure will not fail due to wear during repeated mold replacement, thereby ensuring the long-term stable operation of the equipment.

[0047] More specifically, the center of the rotating seat 2 is provided with an axial hole 24, the axial hole 24 is provided with a rotating shaft screw 6, the rotating shaft screw 6 is sleeved with a bushing 7, and the lower end of the rotating shaft screw 6 is installed on the base 1. This configuration provides necessary rotation support for the rotating seat 2. The bushing 7 on the rotating shaft screw 6 mainly plays the role of friction reduction and positioning, ensuring that the rotating seat 2 moves smoothly during rotation, reducing wear and extending the service life. At the same time, the tight installation of the lower end of the rotating shaft screw 6 and the base 1 ensures the stability and reliability of the entire structure.

[0048] More specifically, the base 1 and the press riveting machine are detachably connected. The detachable connection design between the base 1 and the press riveting machine increases the flexibility of machine layout and maintenance. Through this design, the base 1 can be quickly disassembled and reassembled, which is convenient for upgrading, repairing or moving the press riveting machine between different production lines.

[0049] In further design details, a strip hole 11 is provided in the middle of the base 1, which provides a mechanism for fixing the base 1 to the press. The strip hole 11 is designed to allow a second fastener 8 (usually a screw) to pass through it to achieve a firm connection between the base 1 and the press. Since the strip hole 11 is usually longer than an ordinary hole, it provides adjustment space, allowing the position of the base 1 to be fine-tuned during installation to ensure that the rotating seat 2 can be accurately aligned under the press head.
