Description
Technical field
The present invention relates to a kind of bending machine, relate in particular to a kind of bending machine for quick Fabrication leisure chaise longue support frame.
Background technology
In chair manufacturing technology field, price war has become topmost competitive method.As also bought then oneself assembling of spare and accessory parts, will in price war, be on a sticky wicket, therefore, enterprise need to have the own ability of developing respective accessory.Steel pipe price is relatively cheap and intensity is high, and the stressed rear strength of steel pipe can be disperseed along tube wall, and therefore intensity even exceedes raw steel member, is good a kind of material.Therefore we need to carry out various cold working to steel pipe and make it bending or bending, finally form our needed shape, for the making of chair frame.
Application number is that 201410006424.9 Chinese invention patent discloses a kind of bending machine, it comprises the workbench of base and base top, five mould wheels, the first hydraulic motor and the second hydraulic motors, the oil cylinder of loosing core, wherein, described workbench top is provided with five points two parallel mould wheels that arrange of row, described mould wheel is by the first fluid motor-driven of workbench below, and each mould wheel is provided with the groove with tubing shape adaptation; Described workbench rear is guide rail, the described oil cylinder of loosing core is arranged on guide rail and under the driving of the second hydraulic motor and can slides along guide rail, the described oil cylinder front end of loosing core offers to place the bearing groove of tubing, and the core_pulling pole of this bearing groove projecting inward one and tubing shape adaptation certainly, described core_pulling pole end is between two row's moulds wheels.This bending machine, owing to driving wheel and driven pulley are arranged on to the top of workbench simultaneously, drives driving wheel and driven pulley by hydraulic motor, tubing can be curved to relatively large radius, from radius 1.5m to infinitely great.
Obviously such bending machine can not meet production, and therefore we need to develop the bending machine that is applicable to make leisure chaise longue support frame ourselves.
Summary of the invention
The present invention will solve the problems of the technologies described above, thereby a kind of bending machine that is applicable to make leisure chaise longue support frame is provided.
The technical scheme that the present invention addresses the above problem is as follows:
The bending machine of quick Fabrication leisure chaise longue support frame, it,, for straight pipe is rolled into arc or circle, comprising: feed mechanism, for driving straight pipe to advance; And bending mechanism, the feeding direction and follow feeding of it to make it bend to arc or circle of the pipe that forcibly changing is straight; Described feed mechanism comprises between group and coordinates up and down and drive some wheels that straight pipe is advanced in word order group.
The present invention adopts the principle of forcibly changing direction of feed, and straight pipe is bent, and makes just one-step forming of leisure chaise longue support frame.
As technique scheme preferably, described bending mechanism comprises the top of the some wheels that are arranged on word order or the break-in of below wheel.
As technique scheme preferably, described wheels comprise takes turns and lower whorl, on described, take turns and be installed on frame highly adjustablely, described lower whorl is fixedly mounted on described frame, thereby regulate the spacing of taking turns on described with lower whorl by the height of taking turns on regulating, thereby adapt to the bending of the different straight pipe of caliber.
The present invention adopts the spacing that regulates the height of upper wheel to regulate to take turns on described with lower whorl, thereby adapts to the bending of the different straight pipe of caliber.
As technique scheme preferably, take turns on described by screw body and realize highly adjustable the frame that is installed on.
As technique scheme preferably, described feed mechanism also comprises drive disk assembly, described drive disk assembly comprises gear, takes turns with each lower whorl on each and is connected a gear by rotating shaft, and be connected in the upper lower gear of individual wheels and be meshed.
As technique scheme preferably, described feed mechanism also comprises that regulates wheels, described adjusting wheels are made up of three wheels, wherein two are positioned at the homonymy of straight pipe direction of advance, another is positioned at heteropleural, these three wheels connect gear by rotating shaft equally, and the wheel that is arranged in heteropleural is meshed by described gear with arbitrary wheel of two wheels that are positioned at homonymy, pass through chain transmission in the same way between two wheels of homonymy.
As technique scheme preferably, in three wheels of described adjusting wheels, comprise that wheel in an adjusting, one regulate lower whorl and a pre-break-in wheel; The height that arranges of described pre-break-in wheel is greater than in described adjusting and takes turns lower than the radius of wheel in described adjusting or pre-break-in wheel, thereby make straight pipe entering the first changed course effect through described pre-break-in wheel before described break-in wheel, thereby make straight pipe entering the preliminary bending of generation before described break-in wheel.
The present invention adopts pre-break-in wheel to make the less bending of the first occurrence degree of straight pipe, the larger bending of effect occurrence degree of then taking turns by break-in, thus alleviate the stressed of break-in wheel.
As technique scheme preferably, wheel and regulate the core wheel of lower whorl not on same vertical curve in described adjusting, thus form oblique wheels.
The present invention regulates and takes turns and regulate lower whorl to form oblique wheels, and this is to regulate lower whorl to provide a fulcrum for having an effect of pre-break-in wheel in order to make, and is the equal of to utilize to regulate lower whorl that straight pipe is compressed.Make it not escape in the time processing through pre-break-in wheel; In like manner, pre-break-in wheel also has such effect, because when break-in wheel arranges time too far, the power of the forcibly changing direction producing will become less than normal, make straight steel pipe become indefinite toward any break-in in the time of feeding, and pre-break-in wheel can be offered help in time, the nyctitropic power that changes diminishing is compensated.
As technique scheme preferably, described break-in wheel is connected in described frame by a support; Scalable or the described pre-break-in wheel of described stent length is fixed on described support movably, thereby makes described break-in wheel adjustable with the spacing of described pre-break-in wheel, thereby makes described bending machine can be made into the different circular arc of radius or circle.
As technique scheme preferably, also comprise driving mechanism, described driving mechanism comprises power set, described power set pass to described rotating shaft by chain or belt by power.
As technique scheme preferably, described pre-break-in wheel and the gear being attached thereto are connected in frame by screw component respectively, and two screw mandrels of described screw component lock in the same way by chain and sprocket wheel.
The present invention has following beneficial effect:
The present invention has adopted the principle of forcibly changing direction of feed, and straight pipe is bent, and makes just one-step forming of leisure chaise longue support frame; Also adopt the spacing that regulates the height of upper wheel to regulate to take turns on described with lower whorl, thereby adapt to the bending of the different straight pipe of caliber; And the compensating action that utilizes adjusting lower whorl and pre-break-in to take turns, straight pipe is not escaped in the time there is pressure break-in; The present invention also bends to the different circular arc of radius or circle by regulating the position of break-in wheel to realize.
