Abstract
Description
technical field
[0001] The invention relates to the technical field of auto parts processing, in particular to a straight pipe variable diameter processing equipment for auto parts processing. Background technique
[0002] In automobile pipeline fittings, in terms of oil transportation, exhaust and other aspects, variable diameter tubes are needed. The variable diameter tubes can be used for pressure regulation and distance adjustment. The general variable diameter tubes are heated by the heater. Use a jig to take it out, and then use a tapered die to stamp the reduced diameter.
[0003] After retrieval, for example, the patent No. CN107035145B discloses a variable-diameter mold pipeline device and a diameter-variable method for easy pouring and demoulding, including a mold pipeline, and the mold pipeline is cut into two symmetrical four-piece pipeline segments along the axial direction , are respectively the first pipe sector, the second pipe sector, the third pipe sector ...
