Technical field
The utility model is related to a kind of metal pipe bender with Auxiliary support unit.
Background technology
Bending machine can substantially be divided into CNC tube bending machine, hydraulic pipe bender etc..It is mainly used in power construction, rail-road road is built
If boiler, bridge, ship, furniture, decoration etc. and are built at the pipe laying of aspect, with function it is many, rational in infrastructure, operate it is simple
Single the advantages of.
Its defect be metal tube in BENDING PROCESS, stress situation that its crooked position is received is complicated, fold easily occurs
Or section is oval phenomenon, has a strong impact on bending quality.
The content of the invention
Problem to be solved in the utility model is to provide a kind of metal pipe bender with Auxiliary support unit, overcomes
Deficiency of the prior art.
In order to solve the above technical problems, the technical solution adopted in the utility model is:Metal with Auxiliary support unit
Tube bending machine, including base plate, two support wheels, hydraulic jack and pushing block units, the hydraulic jack are fixed on the base plate,
Push rod is connected with the hydraulic jack, the pushing block unit is detachably connected with the end of the push rod;
The pushing block unit includes middle pushing block and respectively positioned at the side pushing block of the middle pushing block both sides, and the centre pushes away
There is the first arc tube seat on the front end face of block, there is the second arc tube seat on the front end face of the side pushing block, the centre pushes away
After block and side pushing block splicing, the first arc tube seat and the second arc tube seat can form one;
The side of the middle pushing block has and has axostylus axostyle in axial trough, the axial trough, and the side pushing block side has can stretch
Enter the axial trough and the axle sleeve being placed on the axostylus axostyle, there is torsion spring, the two of the torsion spring between the axostylus axostyle and the axle sleeve
End be individually fixed on the axostylus axostyle and the axle sleeve, when the torsion spring in the raw when, in the first arc tube seat
Tangent line at the heart and the tangent line at the second curved pipe groove center are same straight line;
The support wheel is respectively positioned at the both sides of the pushing block unit.
Further, have on the base plate and adjust slide opening with the one-to-one arc of the support wheel, the support wheel
Bottom has flap, and one end of the flap is rotatably connected with the surface of the base plate, and the bottom of the flap is near described
There is the guiding standing screw that the arc can be passed through to adjust slide opening, the bottom tool of the guiding fixing bolt at the flap other end
The upper surface for having nut, the nut can contradict with the lower surface of the base plate.
Further, the both sides of the middle pushing block are respectively provided with gathering sill, and the side of the side pushing block is described with that can stretch into
Guide post in gathering sill.
The utility model has the advantages and positive effects that:Due to using above-mentioned technical proposal, metal tube can be bent
Position provides supporting function, it is to avoid fold or section occurs under stress in crooked position turns into oval phenomenon.

Specific embodiment
As Figure 1-3, the utility model provides a kind of metal pipe bender with Auxiliary support unit, including base plate
1st, two support wheels 5, hydraulic jacks 2 and pushing block units, hydraulic jack 2 is fixed on base plate 1, and push rod is connected with hydraulic jack 2
3, pushing block unit is detachably connected with the end of push rod 3;
Pushing block unit includes middle pushing block 8 and is located at the side pushing block 9 of the middle both sides of pushing block 8, the front end of middle pushing block 8 respectively
There is the first arc tube seat 10 on face, there is the second arc tube seat 11, middle pushing block 8 and side pushing block 9 on the front end face of side pushing block 9
After splicing, the first arc tube seat 10 and the second arc tube seat 11 can form one;
The side of middle pushing block 8 has and has axostylus axostyle 13 in axial trough 12, axial trough 12, and the side of side pushing block 9 has can stretch into axle
Groove 12 and the axle sleeve 14 being placed on axostylus axostyle 13, have torsion spring (not shown), the two ends point of torsion spring between axostylus axostyle 13 and axle sleeve 14
Be not fixed on axostylus axostyle 13 and axle sleeve 14, when torsion spring in the raw when, the tangent line of the center of the first arc tube seat 10 and
The tangent line of the center of two arc tube seat 11 is same straight line;
Support wheel 5 is respectively positioned at the both sides of pushing block unit.
When using, support wheel 5 and pushing block unit jointly clamp workpiece, and now workpiece is in linear state, the first arc
The center of the center of tube seat 10 and the second arc tube seat 11 contradicts with the outer wall of workpiece, as pushing block unit is in hydraulic jack 2
Pushed ahead under drive, the position that workpiece is located at middle pushing block 8 bends, now side pushing block 9 is acted in the elastic force of torsion spring
Under, reverse thrust is played to workpiece, this plays support to the position on workpiece against crooked place both sides to a certain extent
Effect, when side pushing block 9 is spliced into an entirety completely with middle pushing block 8, workpiece completes bending process, and the structure makes work
The rounder and more smooth smooth-going of madial wall of the bending part of part, is not likely to produce fold.
Have on base plate 1 and adjust slide opening 4 with the one-to-one arc of support wheel 5, the bottom of support wheel 5 has flap 5, turn
One end of plate 5 is rotatably connected with the surface of base plate 1, and the bottom of flap 5 has at the other end of flap 5 and can be adjusted through arc
The guiding standing screw 17 of slide opening 4 is saved, the bottom for being oriented to fixing bolt has nut 7, and the upper surface of nut 7 can be with base plate 1
Lower surface is contradicted.Said structure causes position-adjustable of the support wheel 5 on base plate 1.
The both sides of middle pushing block 8 are respectively provided with gathering sill 15, and the side of side pushing block 9 has the guiding that can be stretched into gathering sill 15
Bar 16.
Embodiment of the present utility model has been described in detail above, but the content is only of the present utility model preferable
Embodiment, it is impossible to be considered as limiting practical range of the present utility model.It is all according to present utility model application scope made it is equal
Deng change and improvement etc., all should still belong within patent covering scope of the present utility model.
