Cast-rolling coil stripping trolley with elastic support

Abstract

The invention belongs to the technical field of aluminum foil production equipment, and particularly discloses a cast-rolling coil stripping trolley with elastic support, wherein the cast-rolling coilstripping trolley comprises a coil stripping trolley lifting oil cylinder and a coil stripping trolley tray; an elastic buffer piece is arranged between the coil stripping trolley lifting oil cylinder and the coil stripping trolley tray. Compared with the prior art, the cast-rolling coil stripper car with the elastic support has the advantages that a group of belleville springs are additionally arranged between the top of a piston rod of the cast-rolling machine coil stripping trolley and the tray base of the coil stripping trolley, and the compression space of the belleville springs just meets the thickness of a cast-rolling rolled plate. Through the characteristic that the belleville springs contract slowly when being steessed, the thickness of the rotating wall of a coil is reduced when the trolley unloads coils, force applied to a trolley riding wheel is increased, and thus cast-rolled coil surface deep pressing damage is eradicated. And the detection rate of the cast-rolled coiled plate surface quality defects can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of aluminum foil production equipment, and specifically discloses a cast-rolling coil unloading trolley with elastic support. Background technique [0002] In the production process of aluminum foil, the cast-rolled finished coil needs to be unloaded. In the related art, the unloading trolley of the casting and rolling mill is used to unload the coils. In the related art, the top of the piston rod of the coil unloading trolley of the casting and rolling mill is in rigid contact with the tray base of the coil unloading trolley, and there is no space for expansion and contraction. Therefore, when the coil is unloaded, the pallet of the trolley is in direct contact with the surface of the cast-rolled coil, and the pressure of the oil cylinder is constant, and there is no retraction space. Deep indentations are caused on the outer three layers of the cast-rolled coil, which affects the quality of the cast-rolle...

Problems solved by technology

Therefore, when the coil is unloaded, the pallet of the trolley is in direct contact with the surface of the cast-rolled coil, and the pressure of the oil cylinder is constant, and there is no retraction space. Deep indentations are caused on the outer three layers of the cast-rolled coil, which affects the quality of the cast-rolled coil surface and causes quality defects. The detected rise is 70%, and the height of the trolley needs to be adjusted during the roll cutting process to avoid scratching the inner ring of the roll
