Description
Technical field
The present invention relates to a kind of wrinkle resistant piece of bending machine, and in particular to a kind of wrinkle resistant piece for automobile exhaust tube bending machine.
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.Machine is in addition to possessing bend pipe function, moreover it is possible to used oil cylinder as hydraulic jack, relative to numerical controlled bending of pipe
For equipment have it is cheap, the characteristics of easy to use, bending machine market occupies leading products position at home.Bending machine enters
The bending of row tubing is as the bending of plate.In the case of pure bending, external diameter is D, and wall thickness receives moment of face M for the pipe of t
Effect when bending, tube wall tension stress σ 1 is acted on the outside of neutral line, and tube wall is thinning；Neutral line inner side tube wall tension stress
σ 1 is acted on, and tube wall is thickening.And the shape of cross section from circle by the effect of F1 with joint efforts and F2 due to being changed into approximate ellipsoidal, when
When deflection is excessive, outside tube wall can be cracked, and inner side tube wall occurs corrugation.The deformation extent of tubing, depending on relative
The size of radius of curvature R/D and relative thickness t/D numerical value, R/D and t/D values are smaller, represent that deformation extent is bigger.To ensure pipe fitting
Forming quality, it is necessary to control deformation extent in tolerance band, the tube bending forming limit depends not only on the mechanical property of material
Energy and bending method, and further contemplate the use requirement of pipe fitting.
The fine copper part that wrinkle resistant piece of existing bending machine is typically chosen generally copper alloy is fabricated by, and uses this wrinkle resistant
Block cost is higher, and wrinkle resistant piece itself belongs to running stores again, and slightly abrasion is accomplished by changing, and frequent replacement cost is too high and more
Waste.
The content of the invention
The technical problems to be solved by the invention are that wrinkle resistant piece of replacement cost of existing bending machine is higher, it is therefore intended that provide one
Wrinkle resistant piece for automobile exhaust tube bending machine is planted, existing wrinkle resistant piece is solved and is manufactured by fine copper, and wrinkle resistant piece easily weares and teares, frequently
Replacement cost is too high and the problem that more wastes.
The present invention is achieved through the following technical solutions：
A kind of wrinkle resistant piece for automobile exhaust tube bending machine, including preceding copper billet and latter wrinkle resistant piece, the preceding copper billet is pure by tradition
Wrinkle resistant piece of cutting of copper is formed, and wrinkle resistant piece of edge of traditional fine copper is cut perpendicular to the face in conduit axis direction, is taken and is wherein close to
A part for pipeline rout end, in this section at the distance with tube contacts face 0.5mm cut, cut surface and this portion
Identical with the face shape of tube contacts in point, it is preceding copper billet with the part with the face of tube contacts to be scaled off, described
Wrinkle resistant piece is that the hardware constituted with traditional wrinkle resistant piece of fine copper is matched with preceding copper billet afterwards.By tradition, wrinkle resistant piece is divided into two parts,
Be referred to as preceding copper billet with the part that tube contacts are easily worn and torn, preceding copper billet use with traditional wrinkle resistant block of identical material, it is and former
The part that will not be worn in the course of the work is referred to as latter wrinkle resistant piece, using new metal material inexpensively, preceding
After copper billet abrasion, only need to pull down wrinkle resistant piece preceding copper billet is changed can just be continuing with.
The preceding copper billet with latter wrinkle resistant piece on be also provided with the screw that matches, preceding copper billet is fixed by screws in latter wrinkle resistant piece
On.Using preceding copper billet and the latter wrinkle resistant piece dismounting and replacing being easy to preceding copper billet of being screwed, can be operated at the construction field (site),
The saving time.
The installation screw matched with bending machine is also provided with described latter wrinkle resistant piece.It is easy to be arranged on all kinds of by new wrinkle resistant piece
On angle pipe equipment.
Described latter wrinkle resistant piece uses QSn4-0.3 material manufactures using the manufacture of 40Cr Steel materials, preceding copper billet.40Cr steel is machine
One of most popular steel of tool manufacturing industry.There is good comprehensive mechanical property, good low-temperature impact is tough after modifier treatment
Property and low notch sensitivity；QSn4-0.3 tin bronzes have mechanical property high, corrosion resistance and high resiliency, can well cold
Pressure processing is born under state, also pressure can be carried out under hot adds.Work
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of wrinkle resistant piece for automobile exhaust tube bending machine of the present invention, is only that frequently part uses property high to tube contacts
Can material, low cost；
2nd, a kind of wrinkle resistant piece for automobile exhaust tube bending machine of the present invention, can continue to make after abrasion by changing the part of abrasion
With economizing on resources.
