Technical field
The present invention relates to a kind of bending machine, especially a kind of bending machine that feeding trolley is arranged.
Background technology
The bending machine that feeding trolley is arranged in the market, feeding trolley comprise that little vehicle main body, material folding embrace tube, and material folding is embraced tube and comprised and embrace a tube overcoat, embrace a tube core, jaw to also have an oil cylinder or cylinder.Oil cylinder or cylinder be through promoting to embrace a tube overcoat before push-and-pull hoop, the compressing jaw tightens up clamping pipe, oil cylinder or cylinder through the push-and-pull hoop after pulling embrace an overcoat, jaw opens and unclamps pipe.Bending process, the cylinder or cylinder top tight after the jaws to grip the pipe, cylinder or cylinder top tight force acting on the ring is always through the sliding tube clamp material hold on, turn the feed tube small car space inclination to be overcome hold ring and clamp the material sliding friction between the cylinder, a large force is required, but also easy to bring the car parts feeding damage.
Summary of the invention
The technical problem that the present invention will solve provides a kind of bending machine, does not need bigger strength, just can be on feeding trolley the inclination angle, space of turne tube, and the feeding trolley part is not fragile yet.
For solving the problems of the technologies described above; Bending machine of the present invention; Comprise fuselage, feeding trolley, feeding trolley comprises that little vehicle main body, material folding embrace tube, and material folding is embraced tube and comprised and embrace a tube overcoat, embrace a tube core, jaw; It is characterized in that: the jaw of said feeding trolley provides thrust to compress jaw by flexible member, and flexible member and jaw rotate synchronously.
As a kind of preferred structure of the present invention, armful tube mandrel of above-mentioned feeding trolley is to being fixed on the feeding trolley, and the elastic force of flexible member acts on to embrace outside the tube and puts, and outer being enclosed within of armful tube embraced on the core and can be moved forward and backward.
As another kind of preferred structure of the present invention, the tube overcoat of embracing of above-mentioned feeding trolley is axially fixed on the feeding trolley, and the elastic force of flexible member acts on to be embraced on the tube core, embraces the tube core and in embracing the tube overcoat, can move forward and backward.
During the feeding trolley clamp of above-mentioned bending machine; Owing to do not need oil cylinder or cylinder that thrust is provided; Jaw only provides thrust compressing jaw by flexible member, and flexible member and jaw rotate synchronously, so do not need bigger strength; Just can be on feeding trolley the inclination angle, space of turne tube, and the feeding trolley part is not fragile yet.
Description of drawings
To combine accompanying drawing to describe two kinds of embodiments of the present invention below.
Accompanying drawing 1 is the sketch map of one embodiment of the present invention.
Accompanying drawing 2 is sketch mapes of another embodiment of the invention.
The specific embodiment
Accompanying drawing 1 shows one embodiment of the present invention.In this embodiment, bending machine comprises fuselage 1, feeding trolley, and feeding trolley comprises that dolly main body 2, material folding embrace tube, loose metal device and corner handwheel 3.Material folding is embraced tube and is comprised that jaw 4, jaw open spring 7, embrace tube overcoat 6, embrace tube core 10, flexible member 9, adjusting nut 12.In this embodiment, flexible member 9 is a clamp spring 9.Jaw 4 is installed in through straight pin 5 and embraces tube core 10 front ends; Clamp spring 9 is being embraced between tube overcoat 6 and the adjusting nut 12; Adjusting nut 12 is installed in to be embraced on the tube core 10; Embrace tube core 10 rear portions and be installed in the dolly main body 2, embrace tube core 10 and be axially fixed on the feeding trolley, embrace tube overcoat 6 and embracing on the tube core 10 and can move forward and backward through bearing.Corner handwheel 3 is installed in the rear end of embracing tube core 10, rotates corner handwheel 3, can drive an armful tube core 10 and rotate.The loose metal device comprises loose metal oil cylinder 11 and pulling block 8.Loose metal oil cylinder 11 is fixed on the dolly main body 2.Dolly main body 2 can move forward and backward along track on fuselage 1.Before the clamp, loose metal oil cylinder 11 pulled backwards pulling blocks 8, pulling block 8 pulled backwards are embraced an overcoat 6, move behind the front end of armful tube overcoat 6, and jaw 4 is opening open-shaped attitude under spring 7 effects, and clamp spring 9 is compressed simultaneously.Pipe is put into jaw 4, and loose metal oil cylinder 11 is seen pulling block 8 enough distances forward off, and clamp spring 9 flicks, and clamp spring 9 promotes to embrace tube overcoat 6 and moves forward, and the front end of embracing tube overcoat 6 compresses jaw 4, and jaw 4 draws in holds pipe tightly.Adjustment adjusting nut 12 can be adjusted the clamping force of 4 pairs of pipes of jaw at the front and back position of embracing on the tube core 10.After jaw 4 is held pipe tightly, can begin bend pipe.In the bend pipe process, when the inclination angle, space of pipe need change, rotate corner handwheel 3, embrace tube core 10 and rotate, spring 9, armful tube overcoat 6, jaw 4, pipe rotate synchronously.Because this moment, loose metal oil cylinder 11 was no longer to embracing tube overcoat 6 application of forces, and to embrace tube core 10 rear portions be to be installed in the dolly main body 2 through bearing, be easier to so rotate corner handwheel 3, and the feeding trolley part is not fragile yet.
Accompanying drawing 2 shows another embodiment of the invention.In this embodiment, bending machine comprises fuselage 1, feeding trolley, and feeding trolley comprises that dolly main body 2, material folding embrace tube, loose metal device and corner handwheel 3.Material folding is embraced tube and is comprised that jaw 4, jaw open spring 7, embrace tube overcoat 6, embrace tube core 10, flexible member 9.In this embodiment, flexible member 9 is a clamp spring 9.Jaw 4 is installed in through straight pin 5 and embraces tube core 10 front ends; Clamp spring 9 is being embraced tube overcoat 6 and is being embraced between the tube core 10; Embrace tube overcoat 6 rear portions and be installed in the dolly main body 2, embrace tube overcoat 6 and be axially fixed on the feeding trolley, embrace tube core 10 and in embracing tube overcoat 6, can move forward and backward through bearing.Corner handwheel 3 is installed in the rear end of embracing tube overcoat 6, rotates corner handwheel 3, can drive an armful tube overcoat 6 and rotate.The loose metal device comprises loose metal oil cylinder 11 and pulling block 8.Loose metal oil cylinder 11 is fixed on the dolly main body 2.Dolly main body 2 can move forward and backward along track on fuselage 1.Before the clamp, loose metal oil cylinder 11 spurs pulling block 8 forward, and pulling block 8 spurs the afterbody 13 of embracing tube core 10 forward, embraces 10 reaches of tube core, and jaw 4 stretches out embraces tube overcoat 6, and jaw 4 is opening open-shaped attitude under spring 7 effects, and clamp spring 9 is compressed simultaneously.Pipe is put into jaw 4, and loose metal oil cylinder 11 is seen pulling block 8 enough distances backward off, and clamp spring 9 flicks; Clamp spring 9 promotes to embrace tube core 10 and moves backward; Jaw 4 is advanced for 6 lira to embracing the tube overcoat, and the front end of embracing tube overcoat 6 compresses jaw 4, and jaw 4 draws in holds pipe tightly.After jaw 4 is held pipe tightly, can begin bend pipe.In the bend pipe process, when the inclination angle, space of pipe need change, rotate corner handwheel 3, embrace tube overcoat 6 and rotate, spring 9, armful tube core 10, jaw 4, pipe rotate synchronously.Because this moment, loose metal oil cylinder 11 was no longer to embracing afterbody 13 application of forces of tube core 10, and to embrace tube overcoat 6 rear portions be to be installed in the dolly main body 2 through bearing, be easier to so rotate corner handwheel 3, and the feeding trolley part is not fragile yet.
