Secondary knocking device for aluminum ingot de-molding of aluminum ingot production line

Abstract

The invention discloses a secondary knocking device for the aluminum ingot de-molding of an aluminum ingot production line, and aims to solve the problems of manpower waste, cost increase and low safety of a manual de-molding manner. The device comprises monitoring equipment, a cylinder, a crank, a rotating shaft, a connecting rod and a knocking hammer, wherein the free end of a piston rod of the cylinder is connected with one end of the crank in a rotating manner; the rotating shaft is fixedly connected with the other end of the crank; one end of the connecting rod is fixedly connected with the rotating shaft, and the knocking hammer is arranged at the other end of the connecting rod; after an aluminum ingot which is not smoothly de-molded in a die is monitored by the monitoring equipment, the piston rod of the cylinder extends or retracts to drive the crank to rotate to further drive the knocking hammer through the connecting rod to upwards raise / downwards knock the die to separate the aluminum ingot from the die. When the device is used for knocking the die with the aluminum ingot which is not smoothly de-molded at a de-molding position, a worker is not required to be arranged at the position, so that manpower waste is avoided, production cost is reduced, the de-molding rate of the aluminum ingot is ensured, and the running safety of the device is improved.

Description

technical field

[0001] The invention relates to an aluminum ingot demoulding device in an aluminum ingot casting production line, in particular to a knocking device for secondary knocking on a mold when the aluminum ingot is demoulding. Background technique

[0002] In the aluminum ingot casting production line, the high-temperature aluminum liquid formed by electrolysis flows into the mold and is initially cooled to form the aluminum ingot. The demoulding device separates the preliminarily formed aluminum ingot from the mold, so that the aluminum liquid can be cast in the mold for the next time. However, the aluminum ingot demoulding device cannot guarantee that the demoulding rate of the aluminum ingot reaches 100%. Occasionally, the aluminum ingot cannot be separated from the mold at the demoulding position, so that the aluminum ingot remains in the mold after passing the demoulding position. It will lead to two situations: 1. The aluminum ingot stays in the mold all the...
