Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of nut processing technology, and more specifically, to a high-speed nut stamping forming machine. Background Technology

[0002] In the process of the booming development of modern manufacturing, nuts, as an indispensable basic component of various mechanical equipment, building structures and electronic products, have seen a continuous increase in demand. The production efficiency and quality of nuts are directly related to the overall efficiency and product quality of many downstream industries.

[0003] Traditional nut processing technology has revealed many limitations in the face of today's large-scale and diversified market demands. Early nut stamping equipment had a slow stamping speed, with only a few stamping times per minute, resulting in extremely low production efficiency and making it difficult to meet the current fast-paced production requirements. For example, some simple manual stamping devices require workers to manually place nut blanks one by one and operate the stamping, resulting in very limited output per day.

[0004] In the positioning and clamping process, the traditional method is not accurate enough. For example, if the nut blank is fixed by a simple fixture, the blank is very easy to shift during the stamping process. This will not only cause the nut size deviation, but may also lead to a large number of defective products. Moreover, traditional fixtures can usually only be used for nut blanks of a single specification. Once different specifications of nuts need to be produced, the entire set of fixtures must be changed manually. This process is cumbersome and time-consuming, which greatly affects the continuity of production.

[0005] The versatility of equipment has also become a major problem restricting production. In the past, stamping equipment could only process nuts of specific models and sizes. When market demand shifted to other specifications of nuts, the equipment could not adapt, and companies had to purchase new equipment, which undoubtedly increased production costs significantly.

[0006] As the manufacturing industry places increasingly stringent demands on the efficiency and quality of nut production, it is imperative to develop a forming machine that can achieve high-speed stamping, has precise positioning and clamping functions, and can adapt to the production of nuts of various specifications. This will not only help improve the market competitiveness of nut manufacturers and reduce production costs, but also provide a solid guarantee for the efficient and stable development of the entire manufacturing industry. Utility Model Content

[0034] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] like Figures 1-4 As shown, it illustrates a high-speed stamping forming machine for nuts according to this disclosure, comprising:

[0036] Processing table 1, with a stamping head 2 installed on the upper surface of processing table 1;

[0037] Positioning and clamping assembly 3 is mounted on the processing table 1;

[0038] The driving clamping assembly 4 is disposed on the lower end face of the processing table 1;

[0039] The positioning and clamping assembly 3 includes a positioning groove 3-1, which is located on the processing table 1. A nut groove 3-2 is provided inside the positioning groove 3-1. A sliding frame 3-3 is inserted into the inner side wall of the positioning groove 3-1. A clamping plate 3-4 is provided at the end of the sliding frame 3-3. A stamping cylinder 3-5 is provided on the upper end face of the stamping head 2. A stamping head 3-6 is provided at the telescopic end of the stamping cylinder 3-5. The stamping head 3-6 is positioned corresponding to the positioning groove 3-1.

[0040] The drive clamping assembly 4 includes a drive disk 4-1, which is set on the bottom surface of the processing table 1. The drive disk 4-1 is driven to rotate by a motor. The drive disk 4-1 is provided with a drive spiral pattern 4-2. The bottom of the sliding frame 3-3 is provided with a meshing groove 4-3, which meshes with the drive spiral pattern 4-2.

[0041] In some examples, the press head 2 adopts a right-angle bent structure. This structural design ensures the stability of the press head 3-6 in the vertical direction during stamping, and also makes the installation and arrangement of the press cylinder 3-5 more reasonable. The press head 2 is connected to the processing table 1 by high-strength bolts. Each connection point is equipped with a spring washer and a flat washer to prevent the bolts from loosening under the vibration during the stamping process. The upper end face of the press head 2 is machined with a special mounting groove for mounting the press cylinder 3-5. The lower end of the stamping cylinder 3-5 is provided with a cylinder platform 6, which is fixedly connected to the stamping head 2 by welding. The welding process adopts carbon dioxide gas shielded welding, and the weld is uniform and firm, ensuring the connection strength between the cylinder platform 6 and the stamping head 2. When installing the stamping cylinder 3-5, a special installation tool must be used to ensure that the axis of the stamping cylinder 3-5 coincides with the axis of the stamping head 3-6, and the error is controlled within ±0.03mm to ensure that the force transmission is uniform and accurate during the stamping process.

[0042] The positioning groove 3-1 is located on the processing table 1 and is the position for placing the nut blank. Inside the groove is a nut groove 3-2, which consists of multiple hexagonal grooves of varying sizes to accommodate nut blanks of different specifications. A sliding frame 3-3 is inserted into the inner wall of the positioning groove 3-1. The bottom of the sliding frame 3-3 extends out of the processing table 1 and is movably inserted into the positioning groove 3-1, allowing it to slide freely within the groove. A clamping plate 3-4 is installed at the end of the sliding frame 3-3. Several sliding frames 3-3 and clamping plates 3-4 are evenly distributed on the inner wall of the positioning groove 3-1. When the nut blank needs to be clamped, multiple clamping plates 3-4 can simultaneously apply pressure to the nut blank from different directions, ensuring the nut blank remains stable during the stamping process.

[0043] The drive disk 4-1 is set on the bottom surface of the processing table 1 and is driven to rotate by a motor. The drive disk 4-1 is provided with a drive spiral pattern 4-2, and the bottom of the sliding frame 3-3 is provided with a meshing groove 4-3. The meshing groove 4-3 meshes with the drive spiral pattern 4-2. When the motor drives the drive disk 4-1 to rotate, the drive spiral pattern 4-2 will interact with the meshing groove 4-3, so that the sliding frame 3-3 will move linearly in the positioning groove 3-1, realizing the clamping or loosening action of the clamping plate 3-4 on the nut blank.

[0044] like Figures 1-4 As shown, this embodiment proposes a nut groove 3-2 composed of multiple hexagonal grooves, and the sizes of the multiple hexagonal grooves in the nut groove 3-2 are all different.

[0045] In some examples, the operator selects a suitable hexagonal nut groove 3-2 within the positioning groove 3-1 according to the specifications of the nut to be processed.

[0046] For example, such as Figure 3 As shown, the bottom of the sliding frame 3-3 extends out of the processing table 1, and the sliding frame 3-3 is movably inserted between the positioning groove 3-1.

[0047] In some examples, the drive vortex pattern 4-2 on the drive disc 4-1 interacts with the meshing groove 4-3 at the bottom of the sliding frame 3-3, causing multiple sliding frames 3-3 to slide simultaneously along the dovetail groove of the positioning groove 3-1 toward the center of the positioning groove 3-1.

[0048] For example, such as Figure 3 As shown, there are several sliding frames 3-3 and clamping plates 3-4. Multiple sliding frames 3-3 and multiple clamping plates 3-4 are evenly arranged on the inner wall of the positioning groove 3-1. A stamping groove 5 is provided in the stamping head 3-6. The internal contour of the stamping groove 5 is hexagonal. The stamping groove 5 corresponds to the position of the nut groove 3-2.

[0049] In some examples, the telescopic end of the stamping cylinder 3-5 drives the stamping head 3-6 to move downward, and the stamping groove 5 in the stamping head 3-6 stamps the nut blank in the positioning groove 3-1.

[0050] For example, such as Figure 4 As shown, the stamping head 2 has a right-angle bent structure. The stamping head 2 is connected to the processing table 1 by bolts. The lower end of the stamping cylinder 3-5 is provided with a cylinder platform 6, which is fixedly connected to the stamping head 2.

[0051] In some examples, the lower end of the stamping cylinder 3-5 is provided with a cylinder platform 6, which is fixedly connected to the stamping head 2 by welding. The welding process adopts carbon dioxide gas shielded welding, and the weld is uniform and firm, ensuring the connection strength between the cylinder platform 6 and the stamping head 2.

[0052] When using the equipment, the operator selects a suitable hexagonal nut groove 3-2 in the positioning groove 3-1 according to the specifications of the nut to be processed. Using a special feeding tool, such as tweezers or a vacuum nozzle, the nut blank is carefully placed into the selected nut groove 3-2, ensuring that the center of the nut blank coincides with the center of the nut groove 3-2, with the error controlled within ±0.1mm.

[0053] The operator presses the clamping button on the equipment's control panel, and the motor starts and gradually accelerates to the set speed. The motor starts using a soft start method to reduce the impact on the power grid and the mechanical vibration of the equipment.

[0054] The motor drives the drive disc 4-1 to rotate. The drive spiral pattern 4-2 on the drive disc 4-1 interacts with the meshing groove 4-3 at the bottom of the sliding frame 3-3, causing multiple sliding frames 3-3 to slide simultaneously along the dovetail groove of the positioning groove 3-1 towards the center of the positioning groove 3-1. During the sliding process, the position of the sliding frame 3-3 is monitored in real time by a displacement sensor installed on the sliding frame 3-3. When the sliding frame 3-3 moves to the set clamping position, the motor stops rotating. At this time, the clamping plate 3-4 tightly clamps the nut blank. The clamping force can be adjusted by the motor. The output torque of the machine can be achieved by setting an elastic buffer device between the sliding frame 3-3 and the positioning groove 3-1. During the equipment debugging stage, multiple tests need to be conducted according to different specifications of nut blanks to determine the appropriate clamping force. It is necessary to ensure that the nut blank does not shift during the stamping process, but also to prevent damage to the nut blank due to excessive clamping force. After confirming that the nut blank has been clamped, the operator presses the stamping button on the control panel, and the stamping cylinder 3-5 starts to work. The starting process of the stamping cylinder 3-5 adopts a gradual loading method, that is, it starts at a lower speed. A small pressure is applied to bring the stamping head 3-6 into contact with the nut blank. The pressure and speed are then gradually increased until the set stamping parameters are reached. The telescopic end of the stamping cylinder 3-5 drives the stamping head 3-6 downwards. The stamping groove 5 inside the stamping head 3-6 stamps the nut blank in the positioning groove 3-1. During the stamping process, pressure and displacement sensors installed on the stamping cylinder 3-5 monitor the stamping pressure and stroke in real time to ensure that the stamping process meets the process requirements. After stamping is completed, the operator presses the release button on the control panel. The machine reverses, and the drive plate 4-1 rotates in the opposite direction, causing the sliding frame 3-3 to drive the clamping plate 3-4 to loosen the nut. During the loosening process, the position of the sliding frame 3-3 is monitored by the displacement sensor to ensure that the clamping plate 3-4 completely loosens the nut. Using unloading tools, such as pneumatic push rods or mechanical grippers, the formed nut is removed from the positioning groove 3-1 and placed in the designated collection container. During the unloading process, care should be taken to avoid damaging the formed nut. At the same time, debris and waste in the positioning groove 3-1 should be cleaned in time to prepare for the next loading.

[0055] This high-speed nut stamping forming machine achieves precise positioning and stable clamping of the nut blank through the positioning and clamping assembly 3 and the drive clamping assembly 4. The high-speed stamping forming of the nut is completed using the stamping head 2. Its nut groove 3-2 is designed with multiple hexagonal grooves of different sizes, which can adapt to the production needs of nuts of different specifications, exhibiting high versatility and production efficiency. Strictly following the above implementation methods during the installation, commissioning, and use of the equipment can ensure normal operation and stable stamping quality. Furthermore, regular maintenance and timely replacement of vulnerable parts can extend the equipment's service life and improve the company's production efficiency.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
