Description

Technical Field

[0001] The utility model belongs to the technical field of processing of a lifting bucket of an elevator, and in particular relates to a cold stamping and denting device for the lifting bucket. Background Art

[0002] The elevator is an indispensable raw material lifting equipment in the refractory production process. After a long period of operation, the elevator bucket needs to be regularly repaired or replaced with a new one to ensure the long-term and stable operation of the elevator. Figure 1 As shown, the lifting bucket is V-shaped, and side plates are welded on both sides of the lifting bucket to form a V-shaped space for holding materials. The lifting bucket is usually fixed on the chain of the elevator by nuts, and the driving motor and reducer are used to drive the lifting bucket on the chain to rotate, so as to achieve the purpose of lifting and transporting refractory raw materials. During the mechanical processing of the lifting bucket, the rectangular plate is first bent to form a V-shaped lifting bucket body, and then the side plates are welded on both sides of the V-shaped lifting bucket body. When installing the lifting bucket, bolts are used to pass through the installation surface A of the lifting bucket and fix it to the chain. In order to improve the tightness of the installation of the lifting bucket installation surface A and the chain, a gasket is usually added to the installation surface A. However, adding a fastening gasket to the installation surface A will cause the flatness of the installation surface A of the lifting bucket and the chain to be insufficient, thereby affecting the horizontal posture of the lifting bucket, thereby affecting the lifting amount of the refractory raw materials lifted by the lifting bucket, and at the same time causing vibration during the operation of the elevator, affecting the stability of the lifting operation.

[0003] In the prior art, in order to solve the problem that the installation surface A of the lifting bucket and the chain installation are not flat enough when a fastening gasket is added to the installation surface A, a method of machining a countersink on the installation surface A of the lifting bucket using a machine tool (commissioned to a peripheral processing enterprise) is used to provide a concave recess for the flat installation of the fastening gasket. However, the main technical problem of the above method is that the material properties of the lifting bucket body plate are easily damaged by mechanical processing, which affects the service life of the lifting bucket and requires an increase in the equipment investment cost of the machine tool. Based on the above technical problems existing in the prior art, the inventor has developed a cold stamping and denting device for the lifting bucket, which can well solve the above technical problems existing in the prior art.
