Description

A door cover automatic locking device for a metal baler

technical field

The utility model relates to the field of metal waste baling, in particular to an automatic locking device for a door cover of a metal baler.

Background technique

Metal baler is a large-scale construction machinery and equipment that extrudes scrap iron, scrap aluminum, wire, pipe, plate and other scraps into bales with specific shape, density and size. During the process of extruding scrap metal, the door must be kept closed to extrude the scrap. The current automatic locking mechanism of the door cover of the metal baler is insufficient in strength, the door is not firmly locked, and the bolt shaft is easily dislocated, which makes the locking and centering difficult, the failure rate is high, and the reliability is poor.

The existing metal baler door cover self-locking devices mostly use double hydraulic cylinders to drive two bolt shafts to lock and open the door. The shaft is hinged on the door cover support seat. The door cover support seat has a large volume because it supports double hydraulic cylinders. The end of the piston rod is connected to the door cover through the hinge shaft, and the left and right lock rods are connected to the end of the piston rod. on the two locking levers. The two hydraulic cylinders simultaneously drive the movable sliding seat to move so that the bolt shaft moves forward to lock or retract the door cover to open.

The existing metal baler door cover locking mechanism often increases the safety factor by increasing the pressure and volume, which makes the setting of the safety factor unreasonable: setting an excessive safety factor in the area with a small load will not only lead to waste of materials and increase the cost ; and it will also complicate the structure, which is not conducive to the overall optimization. However, where the stress is concentrated, such as the sliding seat, the thickness is set too small, which is easy to damage the sliding plate; in addition, the preloading pressure required during the door cover locking process is small, and one hydraulic cylinder can meet the pressure requirements. There is no mechanism to prevent one end of the door cover locking mechanism from being lifted, which may easily dislocate the pin shaft, or the designed anti-warping mechanism is too complicated, which wastes manpower and material resources.
