A split support structure for the upper and lower shaft systems of a fin forming machine

Abstract

The invention relates to a split supporting structure of an upper-and-lower shaft system of a fin forming machine. The split supporting structure of the upper-and-lower shaft system of the fin forming machine is characterized in that guide sleeve assemblies I are installed in round holes, a lower die plate of guiding stand columns is installed in cooperation with the guiding stand columns through the round holes, guide sleeve assemblies II are installed in round holes, an upper die plate is installed in cooperation with the guiding stand columns through the round holes, the number of the guide sleeve assemblies I is four, the guide sleeve assemblies I are fixed to the lower die plate through screws III, the number of the guide sleeve assemblies II is four, the guide sleeve assemblies II are fixed to the upper die plate through screws II, and upper die plate springs and upper die plate spring distance rings are installed on the guiding stand columns arranged between the lower die plate and the upper die plate; each upper die plate spring is installed between the corresponding upper die plate spring distance ring and the corresponding guide sleeve assembly II, a lower die plate spring guide rod is installed on each guide sleeve assembly I, each lower die plate spring guide rod is fixed to the corresponding upper die plate spring distance ring through screws I, spring guiding threaded rods are installed on the lower die plate, a die spring is installed on each spring guiding threaded rod, and a side plate is installed on the lower end face of each spring guiding threaded rod. The split supporting structure of the upper-and-lower shaft system of the fin forming machine is good in stability, low in noise, long in service life and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of fin forming machines, in particular to a split support structure for the upper and lower shaft systems of the fin forming machine. Background technique [0002] At present, the upper platen and the lower platen reset device in the frame system of the existing high-speed fin forming machine generally adopt an integrated spring return structure. This structure causes the weight of the upper platen and the spring compression force to act on the lower shaft system and the die stamping. In the system, the lower shaft system and the stamping system of the lower die are subject to great force. At the same time, it also leads to excessive fatigue of the cam surface in the lower shaft system, resulting in wear and pitting, bending deformation of the main shaft, and fracture in severe cases; and the excessive load of the lower die system, resulting in low stamping frequency; loud noise. A high-speed fin forming m...
