  • Publication number: 20230330734
    Abstract: A heavy-load and high-precision transmission mechanism applicable to sheet-metal bending equipment, which includes pressing arms, connecting rods, hinged supports, pressing arm lifting assemblies and pressing arm lifting driving assemblies. The pressing arms are symmetrically arranged on a top part of a rack. A front end part of each pressing arm facing an upper cross beam is hinged with the cross beam through the connecting rod. An intermediate part of each pressing arm or a rear end part of each pressing arm away from the cross beam is hinged on the rack through the hinged support. The rear end part or the intermediate part of each pressing arm is provided with a set of pressing arm lifting assemblies. Each set of pressing arm lifting assemblies is connected with a set of pressing arm lifting driving assemblies. Each set of pressing arm lifting driving assembly includes an all-electric servo motor.

  • Patent number: 11554406
    Abstract: A high-precision heavy-load numerically-controlled flanging machine comprises a machine frame, an edge pressing assembly, a flanging beam and a flanging beam transmission mechanism that comprises an inclined slide rail, an inertia block and two crank-connecting rod mechanisms; the flanging beam is provided with a driving inclined plane; the inclined slide rail is mounted on the machine frame; the inertia block is provided with two non-parallel inclined planes, wherein one inclined plane of the inertia block is slidably mounted on the inclined slide rail to form a sliding pair I, and the other inclined plane of the inertia block is in sliding fit with the driving inclined plane of the flanging beam to form a sliding pair II; cranks of the two crank-connecting rod mechanisms are hinged on the machine frame.
