Abstract
The invention provides a quick die change device and a quick die change method for a rolling die, and solves the problems of difficult die change, low efficiency, large safety risk and the like caused by limited operation space, heavy weight of the rolling die, multiple times of installation and disassembly in the die change process of the rolling die.
Description
Technical Field

In order to reduce inventory risk and accelerate capital operation, the matched major industry factories of the parts approach to the objective of zero inventory management, wherein the time for changing the lines of the required products is short so as to meet the production modes of multiple varieties and small batches.
The rolling type generally follows the principle of deformation distribution of 'one-roll centering, two-roll forming and three-roll finishing', and different first-roll, second-roll and third-roll process curves are designed according to the shape of a product rim. Each procedure of rolling mould is divided into an upper roll and a lower roll, in order to be flexible in adjustment, the upper roll and the lower roll are respectively designed into an inner roll, a middle roll and an outer roll, and a set of complete rolling moulds comprises 18 pieces. The rolling die pieces average about 43kg, with the individual outer rolls weighing between 60-65 kg. In the traditional method for changing the rolling die, workers move one by one on a rolling machine shaft over the shoulder height, and the workers move the same one by one downwards during disassembly, so that the die changing efficiency is low. For the rim line subjected to automatic modification, the front of the rolling process is an automatic device, and no person stands in the space, so that the rolling die needs to be lifted to extend out farther when being installed and disassembled, and the danger that the die drops and smashes people is extremely high. The rim line which is not automatically transformed has a place where workers stand, so that the installation is relatively convenient, but the model rolling weight, particularly the outside rolling weight, still has greater safety risk and labor intensity when the mold changing lifts the counter shaft.
