Description

Technical Field

[0001] The present application relates to the technical field of assembly mechanisms, and in particular to a pressing assembly mechanism and a pipe feeding assembly system. Background Art

[0002] In the current production process, the existing press-fit assembly mechanism has obvious limitations. This mechanism only has the ability to stamp and assemble the side panel on one end of the pipe fitting, which has caused a series of problems in actual production. When the side panels need to be assembled on both ends of the pipe fitting, due to the single function of the mechanism, it has to be processed twice, that is, it needs to be completed through two independent processes. There is a time interval between the two processes, and each process requires preliminary work such as equipment debugging and material preparation, which undoubtedly greatly increases the time consumed by the entire production process, resulting in very low production efficiency.

[0003] In addition, from the perspective of each link of the processing, the steps of expanding the ends of the pipe fittings, installing the side panels, and sealing are implemented separately under the existing production mode. Each step requires special equipment to complete, which means that a large number of equipment with different functions are needed. The use of multiple equipment not only increases the cost of equipment procurement, but also requires more manpower, material and financial resources in equipment maintenance, maintenance, storage, etc. At the same time, the increase in the number of equipment also makes the layout of the production workshop more complicated, increasing the difficulty of production management. Therefore, from the perspective of reducing costs and improving efficiency, it is urgent to develop an integrated device for assembling side panels at both ends of pipe fittings. Through this device, the synchronous processing of each step of the side panel assembly at both ends of the pipe fittings can be realized, thereby effectively solving the current problems of high cost and low efficiency.
