Abstract

The invention discloses a method and a device for plastically connecting metal pipes and plates with one another, and belongs to the technical field of material connection. The device comprises a maledie, an edge pressing ring and a female die. The device and the method have the advantages that the pipes and the plates which are required to be connected with one another are prefabricated, then the pipes can be placed in the female die, the plates can be clamped by the female die and the edge pressing ring, the male die can revolve at the high speeds and can rotate along the axes of the pipesat the low speeds, and the plasticity of the pipes can be enhanced by the aid of friction effects; plastic deformation portions of the plates can be promoted by rolling of the male die to flow into annular grooves of the pipes, and accordingly the pipes and the plates can be quickly and efficiently plastically connected with one another in a green manner; the device is high in production efficiency, low in cost and suitable for mass production and is environmentally friendly; plastic forming modes are adopted by the method for connecting the metal pipes and the plates with one another by the aid of the device, the annular grooves are filled with materials for the plates, connectors are good in quality, high tensile stress can be borne, and the problem of difficulty in connecting plate metal with heterogeneous pipes difficult to weld can be solved by the aid of the method and the device.

Description

technical field [0001] The invention belongs to the technical field of material connection, and in particular relates to a plastic connection method and device between metal pipes and plates. Background technique [0002] In modern industry, pipe parts and plate parts are widely used in manufacturing. The traditional connection between plates and pipes mainly adopts welding process, but there are disadvantages such as low production efficiency, poor repeatability, and environmental pollution. In addition, for materials with poor weldability, it is difficult to realize the connection between the pipe and the plate by welding. Contents of the invention [0003] In order to solve the above-mentioned defects, the present invention provides a plastic connection method and device between metal pipes and plates. The connection method is simple to operate, high in reliability, and strong in practicability; the connection device for realizing the connection method has a simple str...
