Windscreen wiper steel bar bending equipment and method thereof

Abstract

The invention discloses windscreen wiper steel bar bending equipment and a method thereof. Bending operation of a steel bar is achieved by arranging a first cam mechanism, meanwhile, a second cam mechanism is arranged between the first cam mechanism and a middle-position cutting servo, and by means of movement of the second cam mechanism, bending stress generated when the steel bar passes through the first cam mechanism is eliminated. The middle-position cutting servo is arranged on a middle-position cutting transmission device, a steel bar cutting-off servo is arranged on a steel bar cutting-off transmission device, the middle-position cutting servo and the steel bar cutting-off servo can act on a first transmission track of the middle-position cutting transmission device and a second transmission track of the steel bar cutting-off transmission device respectively, and a cutting point and a cutting-off point are controlled, so that the cutting length of the steel bar is convenient to control, and on the other hand, shaking of the steel bar during cutting or cutting off can be reduced, and the accuracy of the cutting and cutting-off positions of the steel bar is guaranteed.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a bending device and method for a wiper steel bar. Background technique [0002] Since both the front windshield and the rear windshield of the car have a certain curvature, the wipers arranged on the front and rear windshields also need to match the curvature of the glass. At present, the steel bar bending machine is usually used to complete the bending operation of the steel bar on the wiper; The line needs to be adapted according to the curvature of the front and rear windshields of each model, so the steel bar bending machine must take into account the general performance, and the traditional steel bar bending machine can basically meet the general performance requirements. Traditional steel bar bending machines include domestic and imported two categories. Among them, domestic bending machines have single functions, poor precision, unstable product performance, and products are pr...

Problems solved by technology

Traditional steel bar bending machines include domestic and imported two categories. Among them, domestic bending machines have single functions, poor precision, unstable product performance, and products are prone to deformation after long-term use; compared with Under the circumstances, the imported bending machine has complex structure, high precision, and the performance of the products produced is more stable, but the imported bending machine is expensive, which has caused a greater burden on small and medium-sized enterprises
