Description
Technical field
The utility model relates to a kind of production equipments of automobile fitting component, are especially a kind of stretch bending module of bending machine.
Background technique
Bending machine is that a straight tube bending is gone out multiple elbows to form the machine of automobile oil pipe.Since a straight tube needs
Pipeline section in multiple and different positions is bent in different directions different angle ability formed automobile oil pipe, so, bending machine possesses top
A variety of different types of modules such as curved, stretch bending and twist and warping, and above-mentioned various types of modules be laid in bending machine different location,
Different angle and different height, to adapt to the complicated molding demand of automobile oil pipe.
As shown in Figure 1, the stretch bending module of the bending machine of the prior art includes fixed frame 101, pulling-down driving cylinder 102 and branch
Seat, fixed frame 101 are installed on the support, and fixed frame 101 is rotatably mounted benchmark idler wheel 103, the cylinder body of pulling-down driving cylinder 102
It is fixed on fixed frame 101, the piston rod of pulling-down driving cylinder 102 is rotatably mounted stretch bending idler wheel 104；Under original state, draw
Curved idler wheel 104 externally protrudes out in benchmark idler wheel 103, and the straight tube for needing to bend is located between two idler wheels.
Its course of work is that the straight tube bent is needed with clamp, and the pipeline section for making the straight tube need to bend is located at two
Between idler wheel, the movement of pulling-down driving cylinder, so that piston rod contracting, and then stretch bending idler wheel is driven inwardly to pull the pipeline section, while base
Quasi- idler wheel resists pipeline section again, in this way, the duct section two idler wheel comprehensive function positions is bent.
The stretch bending module of the bending machine of the prior art has the following deficiencies: the stretch bending idler wheel running track due to the prior art
It is linear, so the maximum bending angle of stretch bending module is no more than 90 degree；Although and twisting and warping the bending angle energy of module
More than 90 degree, but the internal structure for twisting and warping module is complicated, needs to assemble barrel shell, lower pressure bearing, cylinder rotary core and barrel shell axis
Just being able to achieve translation is rotation to a series of parts such as square shaft, the main shaft concentric with square shaft, upper pressure bearing to limit, therefore is made
Assembling process complexity is made, it is at high cost, it is time-consuming and laborious；Moreover, discussing this concept of bending side again, a straight tube is bent into two-section
Afterwards, two-section pipeline section just constitutes a plane i.e. bending side, and bending side, which can regard vertical with the wheel shaft of benchmark idler wheel as, puts down
Face, the lateral position of the stretch bending module of the prior art and lengthwise position are that fixation can not be adjusted, it is clear that are unable to satisfy automobile
The complicated molding demand of oil pipe.
Utility model content
The technical problems to be solved in the utility model, which is to provide, can make the maximum bending angle of straight tube be more than 90 degree and structure
A kind of stretch bending module of relatively simple bending machine.

After using the above structure, a kind of stretch bending module of bending machine of the utility model compared with prior art, has following
Advantage:
The course of work of above-mentioned stretch bending module are as follows: with clamp straight tube and that the pipeline section bent is needed to be located at stretch bending rolling
Before between wheel and benchmark idler wheel, under original state, benchmark idler wheel leans backward, and stretch bending idler wheel and linkage idler wheel are respectively positioned on benchmark idler wheel
Side, at this point, the piston rod of pulling-down driving cylinder retracts, post-tensioning sliding block and then drive straight trough retrogressing, the idler wheel so that post-tensioning links, in turn
So that rotation plectrum is rotated around benchmark idler wheel, stretch bending idler wheel is caused also to rotate backward around benchmark idler wheel, straight tube is by stretch bending idler wheel
Pusher is resisted by benchmark idler wheel again simultaneously, therefore bending occurs, and since the motion profile of stretch bending idler wheel is rotation, and rotary arc
Degree is significantly more than 90 degree, so that the angle that straight tube is bent also significantly increases, hence it is evident that has been more than 90 degree, moreover, compared to existing
The twist and warping module of technology internal structure complexity, it is bright that the module of the application increases only linkage idler wheel, rotation plectrum and straight trough, structure
Aobvious simple, assembling manufacturing also facilitates, at low cost, time saving and energy saving.
As an improvement, fixed frame bottom is equipped with bracket, support is equipped with a lifting driving cylinder, goes up and down the piston of driving cylinder
A lifting column is fixed on bar, lifting column is slidably matched on the support, and the bottom of bracket is fixed at the top of lifting column；In this way,
Driving lifting driving cylinder drives stretch bending module significantly to go up and down, to realize stretch bending module through lifting column, bracket, fixed frame
And the significantly adjusting of bending side lengthwise position, the practicability of the module has further been expanded, it is multiple further to adapt to automobile oil pipe
Miscellaneous molding demand.
As a further improvement, support is made of column, cantilever and connection frame, cantilever is fixed with column, goes up and down driving cylinder
It is mounted on connection frame, sets threaded hole at the top of connection frame, waist-shaped hole is through on cantilever, connection frame and cantilever are passed through across waist-shaped hole
And the bolt for screwing in corresponding threaded hole is fixed；Cantilever is equipped with the rectangular opening that passes through for lifting column, rectangular opening and lifting column it
Between exist for lifting column transverse shifting gap；In this way, since lateral sliding can occur with rectangular opening for lifting column, and bolt
Its lateral position can be slid laterally and locked with waist-shaped hole, so, using the structure, it can significantly adjust stretch bending mould
The practicability of the module has further been expanded in the lateral position of block and bending side, further adapt to automobile oil pipe complexity at
The demand of type.
As further improving, waist-shaped hole is made of upper layer hole and lower layer hole, and upper layer boring ratio lower layer hole is wide, bolt head
It is accommodated in the hole of upper layer and bolt shank is accommodated in lower layer hole；In this way, bolt head completely interior can be received in cantilever, avoid
Bolt head protrudes the installation for interfering with bracket and fixed frame, so that total is more compact orderly.
