Bending double-shaft mechanism

Abstract

The invention discloses a bending double-shaft mechanism. The invention aims at providing a bending double-shaft mechanism which can realize the mass production and fast bending speed and is free from requiring physical power, which comprises a bending motor, a servo motor, a stander and a bracket, wherein the lower ends of the two shafts are provided with a distance block, a needle bearing is sleeved on the two shafts, the top parts of the two shafts are provided with clamping block which clamps the two shafts through screws, a left and a right air cylinders are fixed on a crossbeam above the two shafts, an axis block is arranged inside a motor shaft head, the motor shaft head is installed inside a square groove of a twisting block, the twisting block is provided with holes for holding the two shafts, the twisting block is horizontally arranged on a supporting plate, the bending motor is fixed on a motor plate, two slide shaft sleeves are welded on the motor plate, a transposition air cylinder is fixed on the bracket, the servo motor is installed on one end of a trough plate, the other end of the trough plate is fixed on the supporting plate, a ball screw is installed inside the trough plate and is connected with the servo motor through a coupler, and a feeding platform is fixed on a rolling nut behind the stander.

Description

Technical field: [0001] The invention relates to a bending biaxial mechanism, which is suitable for coil bending processing equipment for manufacturing condensers in the refrigerator industry, and is used for processing S-shaped plates and pipes with similar shapes. Background technique: [0002] The S-shaped bending required to be produced is as figure 1 , the existing bending is composed of the upper motor, the upper crank 3, the left bending shaft 4 to form the left bending assembly, the lower motor 7, the lower crank 6, and the right bending shaft to form the right bending assembly. , it is possible to break the motor shaft, so it can only be used for a small amount of pipe bending (called coil pipe in the industry), not competent figure 1 Bending of the sheet (lath-like) shown. (See figure 2 ), the manual bending is performed by clamping plate 12 to position the workpiece, after penetrating into the inner bending shaft 10, the hand push plate drives 8 to drive the b...

[0002] The S-shaped bending required to be produced is as figure 1 , the existing bending is composed of the upper motor, the upper crank 3, the left bending shaft 4 to form the left bending assembly, the lower motor 7, the lower crank 6, and the right bending shaft to form the right bending assembly. , it is possible to break the motor shaft, so it can only be used for a small amount of pipe bending (called coil pipe in the industry), not competent figure 1 Bending of the sheet (slat-like) shown

(See figure 2 ), the manual bending is performed by clamping plate 12 to position the workpiece, after penetrating into the inner bending shaft 10, the hand push plate drives 8 to drive the bending shaft 9 to bend once, and then withdraws from the inner bending shaft 10, and the workpiece is rotated 180 degrees with the clamping plate 12 Locate the next position and start the next bending (see image 3 ), its disadvantages are: physical effort, slow bending speed, not conducive to mass production
