A mechanism for flattening, trimming, punching and clamping trimming waste of pipe fittings

Abstract

The invention discloses a flattening trimming punching and clamping trimming waste material mechanism for a pipe fitting. The flattening trimming punching and clamping trimming waste material mechanism comprises a working table, the working table is provided with a pipe fitting supporting seat, the pipe fitting supporting seat is provided with an arc-shaped supporting groove matched with the pipe fitting, a clamping pressing block and a pushing pressing block which can move up and down are arranged on the pipe fitting supporting seat, an extrusion sliding block is installed on one side of the arc-shaped supporting groove, a fixed die matched with the extrusion sliding block is installed on the other side of the arc-shaped supporting groove, and a trimming punching sliding block is installed in the middle of the extrusion sliding block. A punching rod is fixed on the trimming punching sliding block, the fixed die is provided with a first abdicating hole and a second abdicating hole which are matched with the trimming punching sliding block and the punching rod, the pushing pressing block pushes the extrusion sliding block and the trimming punching sliding block to move in the direction perpendicular to the axis of the pipe fitting, an upper clamping block and a lower clamping block which can both move up and down are installed on the fixed die on the upper side and the lower side of the first abdicating hole, and a second returning pressure spring is installed between the upper clamping block and the lower clamping block and the fixed die. The flattening trimming punching and clamping trimming waste material mechanism is high in processing efficiency and reliable in motion, and the product specification is good after the processing.

Description

technical field [0001] The invention relates to forming equipment for pipe fittings, in particular to a mechanism for flattening, trimming, punching, and clamping and trimming waste materials for pipe fittings. Background technique [0002] figure 1 Shown is a passenger car seat back frame 10a after molding, and its end 101a is made of figure 2 The end of the arm of the U-shaped pipe fitting 1a is processed by flattening, edge trimming, and punching. The existing processing equipment needs to clamp the workpiece three times and then perform flattening, edge trimming, and punching respectively. The problem is that the processing efficiency is low, and the trimming and punching positions are prone to deviations, and it is difficult to ensure consistent product specifications after processing. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mechanism for flattening, trimming, punching and clamping trimming wast...
