Disassembly-free and hole-free mold width adjustment device for sheet turning and forming machine

Abstract

A disassembly-free and hole-free mold width adjustment device for a sheet turning and forming machine comprises a main shaft, two pressing rollers and a widened wheel, the main shaft is erected on a bearing base, the two pressing rollers are arranged on the main shaft in a sleeving mode, and inner step holes are formed in the opposite surfaces of the two pressing rollers; the widened wheel is formed by combining two half-round wheels, outer steps matched with the inner step holes are arranged on the two planes of the widened wheel, and the widened wheel is arranged on the main shaft in a clamping and sleeving mode and is located between the two pressing rollers; the pressing rollers and the widened wheel are fixed to the main shaft in a pressed mode through fastening assemblies. In the use process, the fastening assemblies are screwed and fastened, and the pressing rollers and the widened wheel are pressed tightly; when the product specification needs to be replaced, users just need to unscrew the fastening assemblies, increase or reduce the widened wheel appropriately and screw the fastening assemblies, the mold change time can be greatly shortened, the labor intensity can be lowered, mold adjustment can be realized without the main shaft, the mold width can be fast increased or reduced without any bolts or auxiliary clamping devices, damage to base metal can be eliminated, and the product quality can be improved.

Description

technical field [0001] The invention relates to the field of thin plate forming machines, in particular to a non-unloading and non-porous mold width adjustment device for a thin plate forming machine. Background technique [0002] The thin plate forming machine is a multi-purpose machine in the construction and machinery industries. Due to the different shapes and widths of the processed products, it is necessary to disassemble all dozens of roller wheels every time the product specification is changed, and then install (or reduce) the dies before proceeding. Installation and height adjustment (need some trial materials) are time-consuming and wasteful. Some manufacturers use semi-circular mold screw clamps to fix, and its disadvantage is that it will leave traces on the base metal plate. Contents of the invention [0003] The invention aims to provide a non-unloading and non-porous mold width adjustment device for a sheet car forming machine. [0004] In order to achiev...
