However, this method requires at least two operators to cooperate with each other to manually operate. It is relatively easy for the smaller "shrimp elbow", but it is not easy to complete the larger "shrimp elbow" even if two people operate it.

The invention relates to the field of machining auxiliary equipment, in particular to preforming equipment for a mitre elbow of a ventilating duct. The preforming equipment for the mitre elbow of the ventilating duct is characterized in that the equipment at least comprises a base, at least three buckling devices and supports of the buckling devices; each buckling device is fixedly connected to one end of the corresponding support, and the other end of each support is supported on the base; the buckling devices and the supports are distributed in a central symmetry mode. The preforming equipment for the mitre elbow of the ventilating duct has the advantages that manual operation can be replaced by a mechanical means, and thus the labor intensity of operators is relieved. All mechanisms on the equipment are arranged reasonably and can be disassembled and assembled independently so that replacement can be conducted rapidly and conveniently by the operators when the mechanisms are damaged or the mechanisms need to be replaced. The pre-buckling effect of pneumatic buckling heads on elbow sections is good, and the connection strength between the two elbow sections is effectively guaranteed.
Description
technical field [0001] The invention relates to the field of processing auxiliary equipment, in particular to a preforming equipment for dried shrimp bends in ventilation pipes, which is used for preparatory processing before the snapping of dried shrimp bends. Background technique [0002] At present, the "shrimp elbow" processing of domestic ventilation pipes mostly adopts "hydraulic shrimp elbow machine" or "mechanical shrimp elbow machine" forming equipment for occlusal processing. However, they all encountered the problem of preparatory crimping of the bent joints before occlusal. Preliminary crimping refers to the pre-withholding of several points at the connecting ends of the two bent joints to ensure that the two bent joints are relatively fixed, so as to facilitate the subsequent "hydraulic shrimp" Elbow machine" or "mechanical shrimp elbow machine" processing. [0003] The traditional pre-clamping method is all done by hand. The steps are to put one elbow with a m...
