Description

A kind of bend forming blank and press-moulding die thereof
Technical field
The present invention relates to pipe fitting processing technique field, be specifically related to a kind of bend forming blank and press-moulding die thereof.
Background technology
Along with progress and the expanding economy of society, fluid line is widely used in every field, its consumption can be rated as basic part, the elbow consumption as fluid line connecting portion is also increasing, imbalance between supply and demand is more and more outstanding, enhances productivity and becomes industry problem demanding prompt solution.The structure of pipeline connecting bend is generally divided into weld ell and shaping elbow, and straight tube material is normally first cut into inclined-plane pipe nipple by the angle of elbow by weld ell, then by two or more pipe nipple docking welding fabrication; And shaping elbow is generally straight tube or straight tube pipe nipple are bent on forcing press or mechanical bend on bending machine, then by two ends excision forming.Traditional elbow-making adopts single piece pressure brake forming mostly.Above-mentioned bending molding process or production efficiency are low, or quality is also difficult to be ensured reliably, up to now, there is no efficient and can the technical method of Reliable guarantee quality.
Summary of the invention
Problem to be solved by this invention is the above-mentioned deficiency overcoming technology, provides a kind of production efficiency high, and can ensure elbow blank and the press-moulding die thereof of Forming Quality.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of bend forming blank, and be multiple elbow conjoined structure, it comprises end and integral angle head part, and otch is left at elbow disjunctor position.
Described end is straight tube-like structure, and both ends are coaxial.
For suppressing a mould for above-mentioned bend forming blank, comprise upper die and lower die, its die joint is curved-surface structure.
Described counterdie two-end part arranges elastic locating mechanism respectively.
Described elastic locating mechanism comprises active module and pull bar, and active module and pull bar are positioned at the step through-hole that counterdie two-end part is arranged respectively, and pull bar installs Compress Spring, and pull bar lower end is threaded stop nut.
The invention has the beneficial effects as follows:
1) bend forming blank of the present invention adopts multiple elbow conjoined structure, be beneficial to the efficiency of elbow press forming operation, once compacting can obtain 7 disjunctors, 9 disjunctors ... the concatemer bend forming blank of 20 disjunctors, than prior art production efficiency can improve more than 20 times; And this structure also to be provided convenience condition to high efficiency cutting, without the need to carrying out one-piece elbow clamping, cutting, can realize continuous cutting.
2) end at bend forming blank two ends of the present invention adopts straight tube-like structure, and both ends are coaxial, is beneficial to the compacting quality reliably ensureing bend forming blank.
3) mould of concatemer bend forming blank of the present invention, for adapting to the warp architecture of concatemer bend forming blank, its upper and lower mould die joint adopts curved-surface structure, at counterdie two-end part, elastic locating mechanism is set, what effectively can ensure that concatemer elbow blank suppresses carries out smoothly, and can reliably ensure the quality of products; As long as in use patrix to be connected to the lower end of press ram, by straight tube Material Containment to be pressed in the die cavity of counterdie, just can be compressing fast.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the structural representation of bend forming blank in the present invention;
Fig. 2 is the structural representation of bend forming blank compacting tool set in the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described.
Embodiment one
As shown in Figure 1 and Figure 2, bend forming blank of the present invention, be the conjoined structure of multiple elbow 1, it comprises end 2 and the integral angle head part at two ends, and otch 3 is left at the position of each elbow 1 phase interconnect.Form concatemer bend forming blank thus, only need cut at otch 3 position after shaping, arrange a little and obtain elbow finished product.This structure is beneficial to the efficiency of elbow press forming operation, once compacting can obtain 7 disjunctors, 9 disjunctors ... the concatemer bend forming blank of 20 disjunctors, than prior art production efficiency can improve more than 20 times.
For suppressing the mould of above-mentioned concatemer bend forming blank, be made up of patrix 4 and counterdie 5, for adapting to the warp architecture of concatemer bend forming blank, its die joint 7 is curved-surface structure, as long as patrix 4 to be connected to during use the lower end of press ram, by straight tube Material Containment to be pressed in the die cavity 6 of counterdie 5, just can be compressing fast.
Embodiment two
Referring to Fig. 1, Fig. 2, the bend forming blank of the present embodiment is the conjoined structure of multiple elbow 1, and it comprises end 2 and integral angle head 1 part at two ends, and otch 3 is left at the position of each elbow 1 phase interconnect.The end 2 at bend forming blank two ends adopts straight tube-like structure, and both ends 2 are coaxial, and this straight-tube portion is reserved stub bar.This kind of structure is convenient to tubing to be pressed and is inserted mould and follow-up compacting, is beneficial to the compacting quality ensureing bend forming blank, and the stub bar that elbow cutting produces also can be used for making other product.
For suppressing the mould of above-mentioned concatemer bend forming blank, be made up of patrix 4 and counterdie 5, for adapting to the warp architecture of concatemer bend forming blank, its die joint 7 is curved-surface structure.Because the die joint 7 of this mould is curved surface, when suppressing bending larger elbow blank, the staggered straight tube groove higher or lower than end of die cavity 6 fluctuation, when the die cavity 6 of counterdie 5 put into by straight tube material to be pressed, by load in the groove of intermediate peak, and when starting to suppress, then the groove at patrix 4 die cavity 5 crest position is first pressed in straight tube material to be pressed, therefore the first stress deformation in crest position of pressing process always patrix 4, counterdie 5 die cavity 6, until just entering in the die cavity 6 of two-end part close to straight tube material to be pressed time shaping.But when the middle part distortion of straight tube material to be pressed, the easy warpage of two ends straight tube, causes accurately successfully falling in the die cavity of two-end part, easily produces compacting waste product.Therefore, present embodiment arranges elastic locating mechanism at counterdie 5 two-end part.Elastic locating mechanism comprises active module 9 and pull bar 10, and active module 9 and pull bar 10 are positioned at the step through-hole 8 that counterdie 5 two-end part is arranged respectively, pull bar 10 install Compress Spring 11, and pull bar 10 lower end is threaded stop nut 12.Before carrying out the compacting of concatemer elbow, by turn stop nut 12, make the groove on active module 9 top concordant with the groove at the crest position of counterdie 5 die cavity 6.Like this, put straight tube material to be pressed then first to fall in the groove of active module 9, drive in the process that presses down of patrix 4 at press ram, straight tube material two ends to be pressed can be in the groove at active module 9 top all the time, spacingly thus can guarantee carrying out smoothly of pressing process.And pressing down along with patrix 4, active module 9 drops to its bottom face and contacts with limited step 13, stops declining, now the groove at active module 9 top and the die cavity 6 of mould ends concordant, form complete die cavity 6 with mould ends, reliably can ensure the compacting quality of concatemer elbow blank thus.
Although illustrate above preferred embodiment of the present invention and describe, so that principle of the present invention and application to be described, should be appreciated that, the present invention otherwise can realize on the basis of not departing from these principles.
