Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical equipment and relates to an automatic installation die device for a corrugated pipe forming machine. Background Art

[0002] A corrugated pipe forming machine based on a die is a device that precisely processes pipes through a die to form a regular corrugated structure, and is widely used in fields such as automobiles, construction, and chemical industry. Its core lies in die design and manufacturing, and the die directly determines the dimensional accuracy, shape consistency, and strength performance of the corrugated pipe. The die usually adopts high-strength alloy or wear-resistant ceramic materials, featuring high wear resistance and long service life. At the same time, precision machining ensures the uniformity of corrugation spacing and depth. During the forming process, the die cooperates with the forming unit to plastically process the pipe through mechanical pressure or hydraulic expansion to complete corrugation forming. The development of modern technology has promoted the evolution of the die towards modularization and intelligence, making it possible to quickly replace the die and adjust parameters in real time to meet the production requirements of different corrugation specifications. In addition, die optimization also focuses on material utilization rate and reduction of springback to improve production efficiency and reduce scrap rate. The forming technology based on the die lays a technical foundation for green manufacturing and industrial automation while achieving high-precision and high-consistency corrugated pipe manufacturing.

[0003] A corrugated pipe forming machine usually consists of more than 16 dies on one side, and a total of more than 32 dies need to be installed on the corrugated pipe forming machine. Each die weighs about 50 kg. Currently, for the installation of dies of different models on all corrugated pipe forming machines on the market, manual labor cooperates with a hoist to lift the die and align it with the die mounting plate on the corrugated pipe forming machine and then fix it one by one. Through actual tests, 3 workers are required to install the die, and it takes more than 11 hours to install all 32 common dies on the corrugated pipe forming machine. Under normal circumstances, manufacturers producing corrugated pipes need to frequently replace dies of different models according to orders. In terms of time, the installation time is too long, seriously affecting production efficiency. More importantly, in terms of safety, in the face of the weight of a single common die of 50 kg, when workers make mistakes, it will cause irreversible harm to the workers, resulting in economic losses to the manufacturer's production and equipment maintenance.

Then, the clamping unit 6 drives the mold A to be installed to move to the mold mounting plate B to be installed by moving along the Z-axis and Y-axis. The swinging assembly drives the mold A to be installed to swing until its bottom is aligned with the slot B1 of the mold mounting plate B to be installed, and then moves the mold A to be installed along the X-axis until its bottom is inserted into the slot of the mold mounting plate B to be installed, completing the installation of the mold A. Finally, control the two jaws 61 to move in the opposite direction to release the installed mold A and prepare to install the next mold A.

[0041] Regarding the support 1: As Figure 1 and Figure 5 shown, the support 1 includes two columns 11. The columns 11 are vertically fixed on the ground, and the two columns 11 are arranged along the Y-axis direction. The Y-axis moving unit 2 is fixed on the two columns 11. Specifically, the lower end of the column 11 is fixed on the ground through the adjusting plate 111, and the top has a Y-axis positioning shaft 112 for positioning the position of the Y-axis moving unit 2.

The Y-direction driving motor 32 drives the Y-axis gear to rotate, thereby driving the moving trolley 31 of the X-axis moving unit 3 to move along the Y-axis guide rail 22 through the Y-axis rack 24.

[0043] Preferably, the Y-axis moving unit 2 further includes two buffers 26. The buffers 26 are fixed to the Y-axis frame 21 through buffer brackets 261. The two buffers 26 are respectively arranged at both ends of the Y-axis guide rail 22 and are used to limit the movement of the moving trolley 31 of the X-axis moving unit 3 for protection.

[0049] Each stopper 52 is connected to the swing arm 51 through a spring 54, and the spring force is used to control the floating of the fixture unit 6 relative to the swing arm 51, that is, if the spring 54 is in a compressed state, the greater the degree of compression of the spring 54, the more difficult the floating, and the smaller the degree of compression, the easier the floating. If the spring 54 is in a tensile state, the greater the length of the spring 54 being stretched, the easier the floating, and the smaller the degree of stretching, the more difficult the floating. During the working state, if there is an error in the alignment between the mold A and the mold mounting plate B of the molding machine, at this time, the spring 54 between the two stoppers 52 and the swing arm 51 in the swing assembly can adjust the error to avoid equipment jamming.
