Thin-wall pipe fitting pipe end forming cutting-off die

Abstract

The invention relates to a cutting-off die, in particular to a thin-wall pipe fitting pipe end forming cutting-off die, and belongs to the technical field of exhaust pipe machining tools. The thin-wall pipe fitting pipe end forming cutting-off die comprises an upper die body and a lower die body which are correspondingly arranged up and down. The upper die body is provided with an upper pipe fitting cavity, and two end pipe port positions of the upper pipe fitting cavity are connected with upper die inserts through connecting pieces. The lower die body is provided with a lower pipe fitting cavity, and two end pipe port positions of the lower pipe fitting cavity are connected with lower die inserts through connecting pieces. Punch installing bases are arranged on the side faces of two end pipe ports of the lower pipe fitting cavity of the lower die body and connected with punch assemblies through connecting pieces. The lower die body is connected with two cutter assemblies, and the twocutter assemblies are connected to the two end pipe port positions of the lower pipe fitting cavity correspondingly. By means of the thin-wall pipe fitting pipe end forming cutting-off die, pipe fitting air inlet and outlet flaring and cutting-off can be finished through one-time positioning, and one device replaces multiple devices to finish multiple procedures through one-time positioning; through one-time clamping, flaring forming of the two ends of a pipe fitting is finished, and product consistency is good; a production line is shortened, and the occupied field is small; and the machiningcost is reduced.

Description

technical field [0001] The invention relates to a cutting die, in particular to a thin-walled pipe end forming cutting die, which belongs to the technical field of exhaust pipe processing fixtures. Background technique [0002] In the mass production process of automobile exhaust system components, manifold pipe fittings have many processing procedures, high processing cost, long production cycle, low production capacity, poor product consistency, and different lengths, which are difficult to meet the requirements of robot welding; thus the design of the pipe End forming and cutting molds meet the requirements of batch processing. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a thin-walled pipe end forming and cutting die, which can ensure that multiple processing procedures can be completed in one clamping of the thin-walled pipe, improves the processing efficiency, and is suitable for mas...
