The specific embodiment
Following with reference to description of drawings embodiment of the present invention.
See also Fig. 1 to Fig. 2; The invention provides a kind of railway fastening elastic rod shaping dies; Be applicable to specific ω type spring is shaped; Described railway fastening elastic rod (as shown in Figure 7) is through after spring blank 9 (as shown in Figure 6) heating with strip, sends into to suppress in this mould to form, and is pressed into finished product (like Fig. 8, shown in Figure 9) through the space fluctuating.
Concrete first embodiment as depicted in figs. 1 and 2, this shaping dies mainly comprises pedestal 1, support 3 and cope match-plate pattern 7.Pedestal 1 is being fixed with bottom roller frame 11; This bottom roller frame 11 is provided with ω type groove 11-1; And the upper roller frame 6 that cope match-plate pattern 7 setting cooperates with bottom roller frame 11, the position of said upper roller frame 6 and the corresponding and said upper roller frame 6 in bottom roller frame 11 positions have the pressure head 6-1 that the ω type groove 11-1 with bottom roller frame 11 adapts.
On bottom roller frame 11, also centrosymmetricly be provided with two U-shaped bending forks 10, it has two ends, and an end pivots with bottom roller frame 11 and is connected, and the other end then is provided with profile roll.
Said support 3 is positioned at the both sides of bottom roller frame 11, is hinged with a lever 4 on the said support 3, and said support 3 also is connected through a spring 2 elasticity with U-shaped bending fork 10, and said U-shaped bending fork 10 is resisted against on the end of said lever 4 all the time.
The top of said support 3 is provided with cam 5; Cope match-plate pattern 7 is provided with the pressure head corresponding with it 8; When pressure head 8 with after cam 5 contacts, can force cam 5 to be rotated, can drive lever 4 then around its pivotal point rotation; Lever 4 and free end and then jack-up fork 10 that U-shaped bending fork 10 backs contact carry out Bending Processing to the spring blank.
When adopting this Mould Machining spring, specifically to implement to machine through two-step method, the first step is to accomplish the plain bending shape; During use, the strip spring blank 9 after the heating is placed on the roller of bottom roller frame 11 and U-shaped bending fork 10, cope match-plate pattern 7 presses down; Upper roller frame 6 touches spring blank 9 backs and bottom roller frame 11 carries out bending forming to spring blank 9 together; After pressure head 8 fixing on the cope match-plate pattern 7 touched cam 5, cam 5 rotations drove lever 4,10 swings of U-shaped bending fork, and the roller of the head of its U-shaped bending fork 10 makes crooked spring blank 9 bending formings; Cope match-plate pattern 7 is up then, leans on spring 2 that U-shaped bending fork 10 is resetted.Like this, the spring of process bending and forming has possessed the ω shape, then; Second step is like Fig. 3 and shown in Figure 4; Also need put into patrix 12 and counterdie 13 formingspace undulations to the spring blank 9 of the plain bending shape that has been shaped, thus, the spring blank adopts two-step method to accomplish shaping.The present invention has also disclosed railway fastening elastic rod shaping auxiliary mould, comprises upper and lower mould, and formed inner space curved surface is consistent with the space curved surface of railway fastening elastic rod after the said upper and lower mould closure.
Accomplish in the shaping dies of plain bending shape in the first step; Roller structure has all been adopted in place contacting with the spring blank; When the plane complicated curved shape of shaping spring; Mainly adopted cam and leverage to promote fork and made spring blank bending forming, utilized spring to reset, guaranteed that the do action of a whole set of mould is reliable and stable.
Fig. 5 has disclosed second embodiment of railway fastening elastic rod shaping dies of the present invention, only is with the difference of first embodiment: cancelled cam 5, leaned on the pressure head 8 direct activation lever 4 completion Bending Processing on the cope match-plate pattern 7.Be provided with like this, whole shaping dies structure is simpler.
The present invention is before the first step is carried out the shaping of plain bending shape; Whether need heat the spring blank; Looking the material character of the spring blank that is adopted decides: if the material of spring blank is more crisp; Toughness is lower, puts into the plain bending shape shaping dies of the first step after then needing in advance the spring blank to be heated; If the spring blank material toughness that is adopted is better, then need not heat it, directly just can put into mould and carry out the shaping of plain bending shape.
The present invention is not limited to aforementioned embodiments, and those skilled in the art also possibly make other changes, but as long as function and the present invention of its realization are same or similar, all should belong to protection scope of the present invention under the enlightenment of technical spirit of the present invention.
