Abstract

The invention discloses a novel plate shearer based on an optimized crank-rocker mechanism. The novel plate shearer based on the optimized crank-rocker mechanism comprises a main shaft of the plate shearer, an upper knife rest and a plate shearer wall plate; the novel plate shearer based on the optimized crank-rocker mechanism further comprises an actuating device, a transmission device, and a blade gap adjusting mechanism; and the actuating device comprises a switched reluctance speed regulation motor and a transmission shaft, the switched reluctance speed regulation motor is connected with the transmission shaft, the transmission device is connected with the actuating device, and the blade gap adjusting mechanism is connected with the upper knife rest. The novel plate shearer based on the optimized crank-rocker mechanism can accurately adjust the blade gap, namely, can continuously adjust the shear angle so as to guarantee the accuracy of processing; and meanwhile enables the actuating device of the plate shearer to achieve stepping speed regulation so that the shearing efficiency is improved.

Description

technical field [0001] The invention relates to a novel shearing machine, which belongs to the field of sheet metal processing equipment. Background technique [0002] The driving devices of the existing shearing machines mostly use conical rotor motors or other asynchronous motors, and their biggest shortcoming is that they cannot realize speed regulation. Simultaneously, in the eccentric wheel and the eccentric link mechanism of the existing plate shearing machine, there is generally sliding friction between the eccentric wheel and the eccentric link, which not only seriously weakens the service life of parts such as the eccentric wheel and the eccentric link, but also It consumes a lot of power and is accompanied by harsh grinding noise. In addition, it can be seen from patents CN2023567U and CN200998795Y that most of the cutter gap adjustment mechanisms of the current shearing machine are a small gear meshing with a large sector gear. The disadvantage is that th...

[0002] The driving devices of existing shearing machines mostly use conical rotor motors or other asynchronous motors, and their biggest shortcoming is that they cannot realize speed regulation

Simultaneously, in the eccentric wheel and the eccentric link mechanism of the existing plate shearing machine, there is generally sliding friction between the eccentric wheel and the eccentric link, which not only seriously weakens the service life of parts such as the eccentric wheel and the eccentric link, but also Consumes a lot of power and is accompanied by harsh grinding noise

In addition, it can be seen from patents CN2023567U and CN200998795Y that most of the cutter gap adjustment mechanisms of the current shearing machine are a small gear meshing with a large sector gear. The disadvantage is that the gear rotation cannot realize the precise and fine adjustment of the knife edge gap, that is, the continuous adjustment of the shear angle cannot be realized.

In addition, the transmission mode of the existing shearing machine is chain transmission, which has low efficiency, severe vibration and shock during the working process, and produces a lot of noise at the same time, which affects the service life of the transmission parts
