Problems solved by technology

[0002] At present, the upper roller and the two lower rollers of the large three-roller bending machine are fixed. If the above-mentioned three-roller bending machine is to be bent into a full circular shell, such as the 80×3500 three-roller bending machine, the upper roller is huge. (6 meters long, 1.3 meters in diameter) and weighs 73 tons. It cannot be moved manually, causing the upper roller to wrap the shell ring in it. The entire circular shell ring cannot be taken out due to the constraints of the upper roller. At least two halves can be bent and then spliced ​​into a full circle, which is a waste of manpower and materials, and can not meet the design dimensional accuracy and mechanical properties, and cannot meet the needs of some products

Embodiment Construction

[0019] The traction system of the three-roller bending machine, taking the 80×3500 three-roller bending machine as an example, includes a pulling-out mechanism, a supporting mechanism, a wedge iron wedge mechanism, and an electrical control part.

[0020] The pull-out mechanism includes a motor 1, a reducer 2, two lead screws 4, two nuts 5, a horizontal bar 6, a large end cap 7, a roller 10, a roller seat 11, a bottom platform 12, and the like. The pulling-out mechanism of upper roller 9 is positioned at front frame 26 outsides, is used for pulling out, sending upper roller 9. A 37KW motor with a speed of 1480r / min is used. The motor 1 is installed on the bracket 13. The output shaft of the motor 1 is connected to the input shaft of two reducers 2 with the same speed ratio of 48.57 through the synchronous belt 3. The two reducers 2 The output shafts are respectively connected to two T160×24 lead screws 4, and the two ends of each lead screw 4 are supported on bearings, and one...

Abstract

A pull system for three-roller plate bender is composed of a bent object pulling out unit having a upper roller linked in leading screw and nut drive mode and driven by motor and speed reducer, a supporting unit consisting of motor, speed reducer, gear, rack bar, sliding body, and square guide, and a wedging unit comprising cylinder and iron wedge. Its advantages are smooth pulling out, uniform speed, and no jamming.

Description

(1) Technical field [0001] The invention relates to large-scale plate bending equipment, in particular to a three-roller bending plate pulling system composed of an upper roll pulling out mechanism, a supporting mechanism, and a wedge iron wedge tightening mechanism. (2) Background technology [0002] At present, the upper roll and the two lower rolls of the large three-roller bending machine are fixed. If the above-mentioned three-roller bending machine is to be bent into a full circular shell, such as the 80×3500 three-roller bending machine, the upper roll is huge. (6 meters in length, 1.3 meters in diameter) and weighs 73 tons. It cannot be moved manually, causing the upper roller to wrap the shell ring in it. The entire circular shell ring cannot be taken out due to the constraints of the upper roller. At least two halves can be bent and then spliced ​​into a full circle, which wastes manpower and materials, fails to achieve design dimensional accuracy and mechanical pr...
