Description

A kind of bending machine
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 by promoting to embrace a tube overcoat before push-and-pull hoop, the compressing jaw tightens up clamping pipe, oil cylinder or cylinder by the push-and-pull hoop after pulling embrace an overcoat, jaw opens and unclamps pipe.In the bend pipe process, after oil cylinder or cylinder hold out against, jaw just can be clamped pipe, the pressure of oil cylinder or cylinder acts on material folding by the push-and-pull ring all the time and embraces on the tube, on feeding trolley, must overcome push-and-pull ring and material folding during the inclination angle, space of turne tube and embrace frictional force between the tube, just need bigger strength, the damage that also easily brings the feeding trolley part.
Summary of the invention
The technical problem to be solved in the present invention 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, material folding is embraced tube and is comprised an armful tube overcoat, embraces a tube core, jaw, it is characterized in that: the jaw of described 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 can move forward and backward in embracing the tube overcoat.
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 to compress 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
Below in conjunction with accompanying drawing two kinds of embodiments of the present invention are described.
Accompanying drawing 1 is the schematic diagram of one embodiment of the present invention.
Accompanying drawing 2 is schematic diagrames of another embodiment of the invention.
The specific embodiment
Accompanying drawing 1 shows one embodiment of the present invention.In the present 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 the present embodiment, flexible member 9 is a clamp spring 9.Jaw 4 is installed in by 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, embracing tube core 10 rear portions is installed in the dolly main body 2 by bearing, 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.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 pulls back pulling block 8, and pulling block 8 pulls back embraces tube overcoat 6, moves 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 sent pulling block 8 enough distances forward, 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.Adjust adjusting nut 12 at the front and back position of embracing on the tube core 10, can adjust the clamping force of 4 pairs of pipes of jaw.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 by 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 the present 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 the present embodiment, flexible member 9 is a clamp spring 9.Jaw 4 is installed in by 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 by 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 sent pulling block 8 enough distances backward, 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 by bearing, be easier to so rotate corner handwheel 3, and the feeding trolley part is not fragile yet.
