Abstract
A thin-wall copper square tube minor radius elbow forming tool is a simple tool for minor radius elbow forming operation in following processing processes of thin-wall copper square tubes and is composed of a bent mould, a clamp block, an auxiliary pushing device, a hard mould core and a crease-resistant block. The auxiliary pushing device and the crease-resistant block are respectively arranged on two sides of the hard mould core, the front end of the hard mould core is of a bendable chain structure, simultaneously the crease-resistant block and the bent mould are in the integral lamination design, a forming wheel is arranged in the middle of the lamination design, a clamp block is arranged at the front portion of the auxiliary pushing device, and a gap is reserved between the auxiliary pushing device and the clamp block. The thin-wall copper square tube minor radius elbow forming tool is simple in process, convenient to process, easy to assembly and simultaneously capable of effectively guaranteeing forming quality of thin-wall copper square tube minor radius elbows.
Description
Technical field
The utility model relates to thin-walled copper square tube minor radius bending tube forming technology, is specially a kind of resistance that is used for when bend pipe, overcoming, the thin-walled copper square tube minor radius bending tube forming instrument of raising amount article rate.
Background technology
The Along with people's growth in the living standard, the design of bathroom hardware industry personalization of product is more and more, and the rectangular tube delivery port is in a large number in our product; Elbow radius for common is bigger, and technology difficulty is also little, but for elbow radius is little and the bend pipe angle is big shown in the figure one product; In the whole machining process process, should guarantee that workpiece is not broken, the wrinkling Deformation control that makes workpiece again is in acceptable scope (being generally below the 0.05mm); And polishing back profile does not have tangible distortion (Deformation control is below 0.3mm); Thereby technology difficulty improves greatly, causes the finished product process more problem to occur, is in particular in that the bend pipe resistance is big; Wrinkling distortion is serious, and amount article rate is low.
The utility model content
The technical problem that the utility model solved is to provide a kind of thin-walled copper square tube minor radius bending tube forming instrument; This is a kind of minimizing resistance; Improve the quick machining tool of the type of flow of material, can be used for solving minor radius, the bend pipe problem of big bent angle thin-walled square tube.
The technical problem that the utility model solved adopts following technical scheme to realize:
Thin-walled copper square tube minor radius bending tube forming instrument is by curved mould, fixture block, auxilliary pushing away; The die core, wrinkle resistant is waited composition, wherein; Auxilliary pushing away and the wrinkle resistant both sides that lay respectively at the die core, die core front end is bent chain structure, simultaneously; Is the integral type stack-design at wrinkle resistant with curved mould, and the centre position of its lamination is provided with briquetting roller; And push away the front portion and be provided with fixture block auxilliary, and auxilliary push away and fixture block between leave the gap.
In the utility model, the parallel position of the briquetting roller in wrinkle resistant should be between fixture block and auxilliary pushing away.
In the utility model, the die core is to be contained in workpiece lumen, guarantees that material is not out of shape to inner chamber when bend pipe, also reduces the bend pipe resistance simultaneously.Wrinkle resistant then opposite with the die core, is to guarantee material not distortion laterally when bend pipe, also can reduce the bend pipe resistance.
In order to guarantee processing needs, adopted auxilliary push away, die core and wrinkle resistant three designs guarantee, assist that to push away be under the effect of hydraulic coupling, in curved mould bend pipe, promote unfashioned material and go ahead, and reduce the bend pipe resistance.
Beneficial effect: the method that the utility model structural design adopts theory analysis to combine with computer modeling technique, the material flowing law of analysis bend pipe deformation process is from confirming optimal processing parameter; With singly open, embedded protected mode designs high-precision composite die up and down, improves anti-deformation, wrinkling ability, reduces the difficult demoulding; Interior system die core clamps; After add the method for auxiliary pull apparatus, control material flowing velocity prevents the wrinkling and attenuation in the bend pipe process.
Description of drawings
The product sketch map that Fig. 1 can realize for the utility model structure.
Fig. 2 is the sketch map of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Sketch map referring to the preferred embodiment of the thin-walled copper square tube minor radius bending tube forming instrument of Fig. 2; Add man-hour; At first be that fixture block 2 is under the effect of hydraulic coupling; Along the clamping direction clamping work pieces, briquetting roller 6 rotates in the drive lower edge of hydraulic pressure for curved mould 3, workpiece and fixture block 2, and workpiece will be processed into the shape of Fig. 1 under the effect of mould.But in the bend pipe process, often cause pipe fitting fracture because of resistance is excessive, therefore install additional and auxilliaryly push away 1, auxilliary to push away 1 be under the effect of hydraulic coupling, promotes undeformed material and flow.
Reduce the bend pipe resistance, auxilliary 1 the speed of pushing away is adjustable, has only to the speed that promotes could reduce the bend pipe resistance to greatest extent when best.Through the pitch of adjustment die core 5, guaranteeing to reduce resistance on the indeformable basis.During wrinkle resistant 4 briquetting roller 6 rotations in curved mould 3 is motionless, only fitting under the very tight situation with curved mould 3, could both guarantee outwards distortion of workpiece, can reduce resistance again.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
