Double-headed spinning system and double-headed spinning method

Abstract

The invention relates to a double-headed spinning system and a double-headed spinning method, and belongs to the technical field of pipe processing. The double-headed spinning system comprises a double-headed spinning device, a pipe end trimming device and a pipe transferring system, wherein the pipe transferring system comprises a pipe transferring clamp jaw; the double-headed spinning device comprises a pipe spinning clamp die and two spinning machine heads; and in the process that the pipe transferring system transfers a pipe processed through the double-headed spinning device to the pipe end trimming device, the pipe transferring clamp jaw is controlled to clamp a pipe clamped on the pipe spinning clamp die before the pipe spinning clamp die releases the clamping on the pipe, and a pipe end trimming clamp die is controlled to clamp the pipe conveyed by the pipe transferring clamp jaw before the pipe transferring clamp jaw releases the clamping on the pipe. According to the spinning system, the processing efficiency on spinning the pipe at two ends is ensured, the follow-up processing quality of the pipe is effectively ensured, and the double-headed spinning system and the double-headed spinning method can be widely applied to the manufacturing fields such as refrigeration, automobiles and aviation.

Description

technical field [0001] The invention relates to pipe processing equipment, in particular to a double-head spinning system and a double-head spinning method suitable for the double-head spinning system. Background technique [0002] like figure 1 As shown, it is a perspective view of a conventional muffler 01, which includes a tubular body 010 and necking structures 011 and 012 located at both ends of the tubular body 010. In the prior art, one end of the straight pipe section 010 is usually spun on a spinning machine to spin out a semi-finished pipe material with a shrinkage structure 011, and the end surface of the pipe is spun with a spinning wheel before spinning. Positioning process, and after spinning, based on the clamping of the tube material spinning clamp, use the tube end trimming unit installed on the spinning head to perform the inner hole and / or flat end surface of the tube end after spinning / or trimming of the inner and outer corners; and then use the spinni...

Problems solved by technology

[0005] in production figure 1 In the process of the muffler with the structure shown in the figure, it is necessary to transport the pipe material between the two spinning machines, which makes the pipe material transfer system more complicated, or the pipe material is turned around on the same spinning machine, and the Resulting in lower production efficiency; and after each spinning process, the second tube material treatment that is different from the spinning process is performed, for example, it is necessary to trim the end of the uneven tube material produced by spinning or the original existing tube material, and there is the problem of multiple positioning
