Shearing machine with speed detection feedback device

Abstract

Disclosed is a plate shearing machine with speed detection and feedback devices. The plate shearing machine comprises a machine frame. An upper tool rest is arranged at the bottom of the machine frame, an upper blade is installed at the bottom of the upper tool rest, and press devices are installed in the upper tool rest and controls press movement of the upper blade. A lower blade is arranged below the upper blade and fixedly arranged on a workbench. The speed detection devices are symmetrically arranged on the portions, located on the two sides of the upper blade, of the machine frame, auxiliary speed adjustment devices are arranged below the speed detection devices, and signals of the speed detection devices are transmitted to the press devices and the auxiliary speed adjustment devices. According to the plate shearing machine with the speed detection and feedback devices, the speed is detected by the use of the speed detection devices on the sides of the upper blade, the signals are transmitted when speed fluctuation happens, the speed of the upper blade is adjusted, and adjustment can be conducted by relying on the press devices of the upper blade, and can also be conducted by the use of the auxiliary speed adjustment devices when the press device cannot timely conduct adjustment.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a shearing machine with a speed detection and feedback device. Background technique [0002] Shears are commonly used plate cutting equipment. After shearing, the shearing machine should be able to ensure the straightness and parallelism requirements of the shearing surface of the sheared plate, and minimize the distortion of the plate to obtain high-quality workpieces. During the cutting process of the shearing machine, the change of the downward speed of the upper blade needs to be within a certain range, especially when the upper blade and the lower blade start to cut, the speed of the upper blade needs to be well controlled, and the entire upper blade is the most It is best not to tilt or have different speeds on both sides, which will easily affect the quality of the sheared product and even affect the use of the equipment.
