Description
Technical field
The present invention relates to a kind of light-wall pipe linkage shaping mechanism, it is adaptable to every profession and trade Small Distance pipeline bending, be mainly used in refrigeration for refrigerator accessory industry, the pipeline bending such as vaporizer, condenser.
Background technology
In refrigeration for refrigerator accessory industry, vaporizer, condenser product are different according to specifications and models, and product can stretch out one or more and manage with the work being connected or install.Owing to connecting or mounting means difference, these pipe fittings are required for bending, and we are frequently encountered by some products that pipe bending is two or more than two, equidirectional, different radii, Small Distance, bending angle are inconsistent of living.
Current existing production technology uses some automatic bending tools or hand bending to put into row manual hand manipulation.Automatically bending tool, can only roll over some spacing, product that radius is bigger, when running into minor radius, Small Distance, uses automatic fixture bending, it is easy to pipe is rolled over flat and pipe can not be taken out, and bothers very much.Owing to being light-wall pipe minor radius bending, needing the way using imposed deformation to ensure the circularity of bending pipeline during bending, this bending method requires that fixed wheel and runner must be all grooved wheels, and runner is the deformation wheel of parabolic shape.Forging Process requires the spacing about 1mm between the deformation wheel edge of fixed wheel and rotation.Owing to space, bending part is less, letting live and take work in Forging Process can not penetrate from groove and pull out, and can only move runner, and the most manual bending all uses the alignment pin in the middle of plug runner, taking-up runner to let live and take work.
So, when running into light-wall pipe, Small Distance, minor radius bending, we generally use hand bending to put into row manual hand manipulation, and workman the most first takes down runner and puts into workpiece, then carries out bending.As it is shown in figure 1, during work, first pull out bearing pin 4, pipe 3 on product is put in the arc groove of fixed wheel 2, being penetrated by runner 5 by bearing pin 4 in the pin shaft hole of connecting plate 6, wherein fixed wheel 2 is penetrated connecting plate 6 by the hole above panel 1 and is connected with screw so that it is connecting plate 6 can be around its rotation again.In side, connecting plate 6 top equipped with handle 7, rotate handle 7 during bending and drive connecting plate 6, runner 5 to rotate together with bearing pin 4, carry out bending.Also need to realize with the separately bending of multiple bending tools when pipe of living is more.When to run into pipe bending alive be two or more than two, equidirectional, different radii, Small Distance, bending angle inconsistent time, generally workman first can break on one side pipe above, after following pipe bending, break by pipe above again, then it is put on another bending tool and carries out bending, after bending completes, then bearing pin 4 and runner 5 are taken off, product is taken out, completes product bending.Although being capable of at present that but bending manual operation labor intensity is big, complex operation, inefficiency, bending angle are not easily controlled plus moving pipe back and forth, pipe is deformed, linearity cannot ensure, is particularly easy to occur that product bending size is inconsistent, bending is flat, scrappage is high.
How to develop a kind of bending being capable of minor radius pipeline, and during bending, be difficult to pipeline folding that partially and to scrap be the target of those skilled in the art's sustained improvement and innovation.
Summary of the invention
The task of the present invention is that proposition is a kind of simple and compact for structure, it is adaptable to Small Distance, minor radius, a kind of light-wall pipe linkage shaping mechanism of many pipeline bendings.
The task of the present invention so completes, it is characterized in that: fixed wheel is set on panel, bending switch block penetrate from the back side of panel connected by washer screw fixed wheel fixing, the other end of described bending switch block is inserted the centre of switch block and is connected by roller pin, it is provided with the hole of assembly deflections wheel on switch block, is placed with packing ring in hole and connects from the bottom of switch block fixing with screw.Described fixed wheel and deformation wheel are highly consistent, the body of fixed wheel and deformation wheel are provided with the groove of bending pipeline, equipped with cylinder on described switch block.Bending switch block and switch block can rotate around it mutually, described switch block and bending switch block are profiled pieces, the shape of switch block such as " 7 " font, the head end of " 7 " font is pointed, described bending switch block is semicircle shape, the overhanging lug of this end face of semicircle inserts the centre of switch block, and the switch block tangent plane above lug is a plane.
The present invention has the effect that the technical program has simple in construction, not only solves that pipeline bending is flat, lives that pipe is many, space is little, different radii, minor radius, bending can not put in place in one-shot forming, bending technical barrier difficult, inefficient, operation complexity is loaded down with trivial details waits technical barrier.

Detailed description of the invention
nullThe technical program uses linkage as pipeline bending，A kind of light-wall pipe linkage shaping mechanism of many pipeline bendings，It is embodied as such as Fig. 2、Shown in Fig. 4，Fixed wheel 2 is set on panel 1，Bending switch block 8 penetrates from the back side of panel 1 and connects fixing by packing ring 14 screw 13 fixed wheel，The other end of described bending switch block is inserted the centre of switch block 12 and is connected by roller pin 9，Can rotate mutually，The hole of assembly deflections wheel 11 it is provided with on switch block 12，It is placed with packing ring 14 in hole and connects from the bottom of switch block fixing with screw 13，Described fixed wheel 2 and deformation wheel 11 are highly consistent，Described bending switch block 8 and switch block 12 can rotate around it mutually，Described deformation wheel can rotation，Furtherly，The groove of bending pipeline it is provided with on the body of fixed wheel 2 and deformation wheel，Equipped with cylinder 10 on described switch block.
Described switch block 2 and bending switch block 8 are profiled pieces, the shape of switch block 12 such as " 7 " font 15, the head end of " 7 " font is pointed, and described bending switch block is semicircle shape, the overhanging lug 17 of this end face of semicircle 16 inserts the centre of switch block 12, and above lug, the tangent plane of switch block is a plane.
The centre-to-centre spacing of described fixed wheel 2 and deformation wheel 11 just can be put pipe fitting 3 and blocked, and is spaced about 1mm between deformation wheel and fixed wheel edge at this moment.
When described pipe fitting needs bending, switch block 8 is promoted to rotate by cylinder 10, when when switch block rotates counterclockwise, pointed part thereon contacts the tangent plane of bending switch block 8, it is made to produce self-locking, can not open again, at this moment fixed wheel 2 and deformation wheel 11 open (as shown in Figure 4), the distance opened enough puts into pipe fitting, the groove of deformation wheel 11 and fixed wheel 2 put into by pipe fitting, cylinder promote moving block rotate clockwise drive fixed wheel 2 and deformation wheel 11 along with together with rotate, when switch block overlaps with the tangent plane on bending switch block, make it produce dead point and be no longer able to turn (as shown in Figure 6), pipe fitting achieves bending.
For realizing one time, the little space of this multi-pipeline bending and molding, employing takes, fixed wheel and deformation wheel are separated by square tube part, clamp during bending, clamping and flexing movement are linked and carries out, one action realizes, owing to this bending structure is compact, both ensure that a bending completes, met again pipeline closely spaced bending demand.
