Abstract
The utility model relates to a vertically pre-bent device of rib cold benders, which is composed of an orbit, a middle machine frame, a side machine frame, a power source, side lower clamping heads, side upper clamping heads, a side clamping oil cylinder, middle upper clamping heads, a middle clamping oil cylinder, middle lower clamping heads, a support screw, a worm wheel, a worm screw, etc., wherein the power source can be a motor, a hydraulic motor or a hand wheel. As a combined driving mechanism which is composed of the worm wheel, the worm screw and the support screw is adopted to drive the side lower clamping heads to move up and down in the side machine frame, the clamping surfaces of the two side lower clamping heads and the clamping surfaces of the middle lower clamping heads can be arranged on different planes, and a height difference is arranged. When rib sectional material is clamped, the sectional material which is filled between middle clamping heads and the two side clamping heads is vertically bent in advance. When ribs are bent and processed, the side bending phenomenon of the sectional material can be eliminated. The utility model has the advantages of simple and simple mechanism, convenient installation, operation and use, etc. The utility model is suitable for processing the components of the rib, the cross beam, the longitudinal bone, etc. of ships, etc., which have curved shapes.
Description
Technical field
The utility model relates to a kind of shipbuilding equipment, especially relates to the vertical pre-bending device of a kind of cold-frame bender.
Background technology
Most of hull frames all are asymmetric section bars, when three fulcrums are crooked, generally by the clamping of machine frame at two sides chuck, by mid frame and chuck thereof moving forward and backward in orbit, apply bending force on preceding (back) direction, promptly section bar are carried out horizontal curvature.But, after the shape bending resilience, the flexural deformation on obtaining horizontal direction, also produced disadvantageous flexural deformation in vertical direction, be referred to as " side sway " usually.For eliminating this disadvantageous " side sway " distortion, make generally that to have certain height between both sides lower chuck and the middle lower chuck poor, form vertical pre-bending, after the horizontal curvature resilience, offset " side sway " phenomenon that rib occurs, obtain smooth rib workpiece, improve the forming quality of rib clod wash processing, reduce follow-up correction work.As the cold-frame bender of Japanese fuji, proofread and correct " side sway " with the mode that places pad, its shortcoming is that pad is spurred by frictional force, damages easily, and troublesome poeration.The cold-frame bender of Britain HUGH SMITH (ENG) LTD in the mid frame bottom of complexity, is provided with the mechanism of vertical pre-bending oil cylinder in addition, and in order to smoothing rib, there is the shortcoming of maintenance difficult in mechanism's complexity of this device.
Summary of the invention
The purpose of this utility model is to provide a kind of vertical pre-bending device of simple in structure, easy to operate cold-frame bender.
The purpose of this utility model is achieved in that by track, mid frame, side frame, power source, side lower chuck, side upper grip, side clamping cylinder, middle upper grip, middle clamping cylinder, middle lower chuck, supporting screw, worm gear, worm screw etc. to be formed.
The side lower chuck is installed on the forming mill side frame, and worm screw is installed on the side frame, and power source is connected with worm screw, and worm gear is supported by the side frame lower end.By the screw pair of worm gear and supporting screw, supporting screw can move up and down.The combination transmission mechanism driving side lower chuck of being made up of worm screw, worm gear and supporting screw moves up and down in side frame.In clamping cylinder connect in upper grip drive it and move up and down, the side clamping cylinder connects the side upper grip and drives it and move up and down.Structure on two side frames is identical, is arranged symmetrically in the mid frame both sides.Power source can be motor, hydraulic motor or handwheel
The course of work of the present utility model is such: the worm screw rotation on the drive power source side frame, worm screw drives the worm gear rotation of being supported by the side frame lower end, screw pair by worm gear and supporting screw, supporting screw is moved up and down, drive the side lower chuck by supporting screw again and realize rising and descending.Make the clamping area of the clamping area of two side lower chucks and middle lower chuck thus not on same plane, a difference in height is arranged.After the middle upper grip that the side upper grip that the side clamping cylinder drives, middle clamping cylinder drive is pushed down fabircated shapes, just the rib section bar has been carried out vertical prebuckling.General rib section bar panel is down the time, if just curved, the both sides lower chuck will move down, if recurvation, then the both sides lower chuck should move up.The size of vertical pre-bending amount can be regulated, thereby can realize eliminating " side sway " phenomenon that occurs after the resilience of rib shape bending.
The utility model has been owing to adopted the combination transmission mechanism driving side lower chuck of being made up of worm screw, worm gear and supporting screw to move up and down in side frame, and it is simple and reliable to have a mechanism, is convenient to installation and advantage such as easy for operation.
