Plate shearing machine with multiple shearing speeds

Abstract

The invention relates to a novel plate shearing machine with multiple shearing speeds. The novel plate shearing machine comprises an electric appliance part, a brake motor, a three-stage gear speed-variable transmission device and a machine body part, wherein the electric appliance part is used for commanding the brake motor to drive a main shaft to rotate through the three-stage gear speed variation, and a chain rod arranged on the outer side of a composite sleeve of an eccentric wheel pulls an upper cutter holder to move vertically, so as to realize shearing purposes. The novel plate shearing machine has the advantages that 1, the torque is increased through the three-stage gear speed variation so as to solve the requirement of shearing power, a standby one-stage small gear of which the number of variable teeth is changed is displaced along with the brake motor so as to realize the requirement of multiple shearing speeds, and the brake motor operates during shearing and stands during non-shearing so as to save energy; 2, the back part of a sliding arm seat of the upper cutter holder is provided with a fixing seat which is matched with a tightening bolt, a thrust nut and a locking nut for use, then the lower end of the sliding arm seat can move to the left and right, and an upper cutter blade and a lower cutter blade are adjusted to a reasonable gap according to requirements so as to reduce burrs of the sheared plates; and 3, a plate pressing structure is provided with a leg pressing shaft so as to avoid the impact by the sheared plate, and a plastic sleeve of the leg pressing shaft has no scratch on the sheared plate.

Description

Technical field [0001] The invention relates to a new sheet metal shearing machine, that is, a multi-shear speed shearing machine. Background technique [0002] At present, the shearing machines mainly used in the market are Q12 hydraulic shearing machine, Q11 mechanical shearing machine and Q11DK electric control shearing machine. They are the mainstream products selected by customers in production, and hydraulic shearing machines are prone to oil leakage. , Seals are easily damaged, maintenance is difficult, mechanical shears are noisy, clutch parts are easy to wear, difficult to maintain, and the three types of hydraulic, mechanical, and electronically controlled shears all have a single shear speed. Contents of the invention [0003] The purpose of the present invention is to provide a new multi-shear speed shearing machine, which adopts a three-stage speed change gear in the structural design, integrates the deceleration and transmission, and replaces the reducer and ...
