Abstract
The utility model discloses a chain die structure comprising a male die and a female die. The male die is provided with male die side faces and a male die cutting edge face. The female die is provided with female die side faces and a female die cutting edge face. The male die side faces are vertical to the male die cutting edge face, and the female die side faces are vertical to the female die cutting edge face. Hardening layers, with a thickness of 0.1mm, are arranged on the female die cutting edge face and the female die cutting edge face. The die structure as proved by punching and producing, punching time of the male die and the female die pieces are exponentially prolonged, die repairing time is reduced, and frequency of changing the male die and the female die is further reduced (if the hardening layer is worn away, the die can be processed by laser and used continuously). Owing to interaction of the hardening layer and matrix toughness, strength of the cutting edge faces is guaranteed, abrasion in punching process is reduced, and continuously punching of the die is benefited; and die steel with fine toughness can be selected as the matrix, so that when the male die is processed, length of the male die can be increased limitedly, and the die-steel-made matrix is adaptable to slender male dies.
Description
Technical field
The utility model relates to the blanking die of the carrier bar of a kind of mould, particularly a kind of chain.
Background technology
The fields such as existing automobile engine silenet chain require the carrier bar profile of chain and counterpart to have motion, and the required precision in hole almost reaches finishing requirements; Therefore require to improve mould and die accuracy, adopt simultaneously minimum blade clearance; Punch and die are in the punching process like this, and their wear extenies are multiplied, and the frequency that repairs a die of part is increased, and punch and die replacement frequency also have increase in various degree simultaneously, have reduced production efficiency, produce order delivery and lag behind.
The utility model content
In order to solve the above problems, the purpose of this utility model is to provide a kind of mould structure of chain, makes the punching time lengthening of mould, has reduced the time of repairing a die, and has reduced the more frequency of mold exchange.
The utility model adopts following technical scheme:
A kind of mould structure of chain, comprise punch and die, punch side and punch cutting edge face are arranged on punch, die side and cutting edge of die face are arranged on die, the punch side is vertical with punch cutting edge face, the die side is vertical with the cutting edge of die face, is provided with quench-hardened case on described punch cutting edge face and cutting edge of die face, and quench-hardened case thickness is 0.1mm.
The mould structure of chain of the present utility model becomes to produce proof through punching, and the punching time of part punch and die extends at double, has reduced the time of repairing a die.Reduce the frequency (as the quench-hardened case wearing and tearing totally, laser treatment, continue to use again) of changing punch and die.
Due to toughness and the quench-hardened case interaction of matrix, guaranteed like this intensity of cutting edge face, reduce wear in the punching process, be beneficial to the continuous punching of mould, and matrix can be selected toughness mould steel preferably, like this when the processing punch, can limited increase punch length, be fit to use elongated male die.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As Fig. 1, a kind of mould structure of chain, comprise punch 5 and die 6, punch side 3 and punch cutting edge face 1 are arranged on punch 5, die side 4 and cutting edge of die face 2 are arranged on die 6, and punch side 3 is vertical with punch cutting edge face 1, and die side 4 is vertical with cutting edge of die face 2, be provided with quench-hardened case 7 on described punch cutting edge face 1 and cutting edge of die face 2, quench-hardened case 7 thickness are 0.1mm.
Select suitable a kind of mould steel, processing characteristics combined influence according to technological requirement and mould, processing punch side 3 with die side 4 with respect to punch cutting edge face 1 is vertical with cutting edge of die face 2 separately, and perpendicularity should guarantee to guarantee simultaneously the roughness of each side at Ra0.8 once in the 0.01mm scope.Processing is during punch, increases 0.01mm on original profile basis, and namely 0.01mm(blade clearance Z-0.01mm is reduced in the blade clearance); When in like manner processing die, concave die cavity reduces 0.01mm in original size, and namely the blade clearance reduces 0.01mm(blade clearance Z-0.01mm again); The punch that processes like this and the fit clearance of die have reduced 0.02mm (blade clearance Z-0.02mm) on original reasonable basis again; For following process lays the foundation.
After part punch and die Precision Machining, with laser scanning punch cutting edge face 1 and cutting edge of die face 2, make this Surface absorption luminous energy, rise to rapidly high temperature, and then undergo phase transition, then pass through cooling fast so that the piece surface modification; Make it process the surface and strengthened, improve hardness, intensity, wearability, the heat-resisting quantity of piece surface, change the combination property of mould punching part cutting edge, improve the punching ability.After punch cutting edge face 1 and cutting edge of die face 2 are processed by laser quenching, the distortion of trace is arranged, obtain hardness, quench-hardened case 7 that wearability is higher, the thickness of the present embodiment quench-hardened case 7 is set to 0.1mm, can have so enough wearabilities to make again the laser quenching cost less; Matrix beyond quench-hardened case still keeps original toughness of material, to guarantee normally carrying out of under repeated stock effect punching.
Part punch cutting edge face 1 and and 2 laser quenchings of cutting edge of die face process, although obtained more satisfactory quench-hardened case, part quench-hardened case part has also produced micro-deformation, needs mutually to grind; The mutual facing-up mill of part, the adverse effect of bringing to punching to eliminate micro-deformation.
Become to produce proof through punching, the punching time of part punch and die extends at double, has reduced the time of repairing a die.Reduce the frequency (as the quench-hardened case wearing and tearing totally, laser treatment, continue to use again) of changing punch and die.
Toughness and quench-hardened case interaction due to matrix, guaranteed like this intensity of cutting edge face, reduce wear in the punching process, be beneficial to the continuous punching of mould, and matrix can be selected toughness mould steel preferably, like this in processing during punch, can limited increase punch length, be a good selection using elongated male die.
