Endpiece redundance is clipped, the waste of raw material is caused.In addition, due to the cantilever method of clamping of this clamping device, lean on
The part of nearly bending section does not support well so that tubing the phenomenon that bending section is susceptible to drawing crack in bending.
Utility model content
Technical problem to be solved in the utility model is：A kind of stock utilization making bending machine bending tubing is provided
The pipe clamping apparatus of the bending machine feeding trolley greatly improved.
In order to solve the above technical problems, technical solution used by the utility model is：The tubing of bending machine feeding trolley
Clamping device, including it is hinged on the push oil cylinder on trolley body top, the piston rod end for pushing oil cylinder is hinged with push rod, pushes away
The other end of bar is sent to be hinged on the lower hinged seat that clamp axle sleeve exit is set in trolley body；Clamp axle sleeve stretches out small
Sliding sleeve is equipped with pushing clamping sleeve on the part of vehicle ontology, and the promotion slot that annular is equipped at the position of push rod is corresponded on pushing clamping sleeve,
Push rod is equipped with the embedded drive block for pushing slot, and pushing clamping sleeve stretches out center in the end of clamp axle sleeve and is equipped with connecting seat, connection
Seat is connect by several wing plates uniformly distributed around central shaft with pushing clamping sleeve, and connecting seat is equipped with driving tube；If clamping jaw fixed seat by
The dry rest shoe between wing plate is connected with clamp axle sleeve, and clamping jaw fixed seat is equipped with the tensioner of tubulose, and tensioner is far from folder
One end inner wall of pipe sleeve is in coniform, if one end far from clamp axle sleeve in tensioner is equipped with the axial arranged tensioning slot in arterial highway
Mouthful；Driving tube is stretched into across clamping jaw fixed seat in tensioner, and driving tube end is and tensioner inner circle taper matching ends
Taper.
As a preferred solution, the drive block is equipped with and pushes the matched scroll wheel of slot.
As a preferred solution, the tensioner periphery is equipped on the part equipped with tensioning notch and is encircled into annulus
With with the matched convex block of pipe fitting inner wall to be tensioned.
The utility model has the beneficial effects that：Tensioning clamping is carried out to tubing due to being stretched into inside tubing using tensioner,
Can directly clamping by bending pipes position, avoid processing after also need material waste caused by cutting off extra section；In addition by
It plays a supporting role to tubing in tensioner, considerably reduces tubing and the situation of drawing crack occur in bending.
Since drive block is equipped with and pushes the matched scroll wheel of slot so that drive block can more swimmingly drive push-tight
Set.
Due to tensioner periphery equipped with tensioning notch part on be equipped be encircled into annulus with pipe fitting inner wall to be tensioned
Matched convex block not only reduces machining accuracy, and makes tensioning clamping more reliable.

Specific implementation mode
Below in conjunction with the accompanying drawings, the specific embodiment of the utility model is described in detail.
As shown in Figs 1-4, the pipe clamping apparatus of bending machine feeding trolley, including it is hinged on pushing away for 1 top of trolley body
Oil cylinder 2, the piston rod end of push oil cylinder 2 is sent to be hinged with push rod 3, the other end of push rod 3, which is hinged on, to be arranged in trolley
On ontology 1 on the lower hinged seat 5 in 4 exit of clamp axle sleeve；Clamp axle sleeve 4 stretches out sliding sleeve on the part of trolley body 1 and is equipped with
Pushing clamping sleeve 6, corresponds on pushing clamping sleeve 6 at the position of push rod 3 and is equipped with the promotion slot of annular, and push rod 3 is equipped with embedded push
The drive block 7 of slot, drive block 7 are equipped with and push the matched scroll wheel of slot 8.Pushing clamping sleeve 6 stretches out in the end of clamp axle sleeve 4
Center is equipped with connecting seat 9, and connecting seat 9 is connect with pushing clamping sleeve 6 by several wing plates 10 uniformly distributed around central shaft, set on connecting seat 9
There is driving tube 11；Clamping jaw fixed seat 12 is connected by several rest shoes 121 between wing plate 10 with clamp axle sleeve 4, and clamping jaw is solid
