Tool gap adjusting mechanism

Abstract

The invention belongs to the technical field of shearing equipment, and particularly relates to a tool gap adjusting mechanism. The tool gap adjusting mechanism comprises a machine frame, a fixed tooland a sliding tool, wherein the fixed tool and the sliding tool are arranged oppositely; the fixed tool is fixedly connected with the machine frame; the sliding tool is slidably connected with the machine frame; the tool gap adjusting mechanism further comprises a driving mechanism arranged on the machine frame or arranged outside the machine frame; the driving mechanism is in driving connectionwith a screw rod through a transmission assembly; the screw rod is sleeved with a sliding block; the sliding block is in threaded connection with the screw rod; the tool gap adjusting mechanism further comprises a pushing block; and by rotating the screw rod, the sliding block can be pressed on the pushing block, the cross-sectional area of the end, close to the screw rod, of the pushing block islarger than that of the end, away from the screw rod, of the pushing block, inclined surfaces are pushed to be connected with the two ends of the pushing block, and by sliding the pushing block, the inclined surfaces can be pushed to press on the sliding tool. The tool gap adjusting mechanism is convenient to operate when a tool gap is adjusted, meanwhile, the adjustment precision is high, the tool gap adjustment range is large, and thus the applicable range of the tool gap adjusting mechanism is enlarged.

Description

technical field [0001] The invention belongs to the technical field of shearing equipment, and in particular relates to a tool gap adjustment mechanism. Background technique [0002] The flying shear is an important equipment responsible for cutting in the flying shear line. The adjustment mechanism for adjusting the tool gap in the prior art generally has the problems of low adjustment accuracy and inconvenient adjustment. [0003] For example, a Chinese utility model patent discloses a tool gap adjustment device for a pendulum shearing machine [application number: 200720066913.9]. This utility model includes an upper knife and a knife holder. The knife rest is arranged in the frame of the shearing machine, the rear end of the knife rest is provided with a knife rest shaft, and the eccentric sleeve is set on the knife rest shaft, and the eccentric sleeve is connected with a The eccentric wheel is connected, and the eccentric wheel is fixedly arranged in the end face of a s...

Problems solved by technology

[0004] The utility model uses the cooperation of the adjustment gear and the sector gear to change the orientation of the eccentric wheel, and uses the eccentric wheel to adjust the radius of gyration of the upper knife, so as to realize the adjustment of the gap between the upper knife and the lower knife. The adjustment accuracy of this adjustment method is still needs to be improved
