Abstract
The invention discloses a stretched thinned terrace die for an air-conditioner fin and relates to a punching stretching processing mould field, a groove is arranged on the outer wall, the connection position of the circumference of the outer wall and the groove is provided with an arc uplifting part. The contact area of the stretched thinned terrace die and the hole wall of the fin can be reduced through the structure, thereby avoiding the surface blacking of the product, and simultaneously, the wear of the terrace die is reduced.
Description
Technical field
The present invention relates to the punch of punching stretch processing mold field, especially tension-thining.
Background technology
A kind of fin of air-conditioning need to carry out punching man-hour and leave simultaneously certain thickness flange around the hole adding, and then carries out tension-thining for flange at vertical direction and processes, thereby improve the height of flange.The punch of present tension-thining mould as shown in Figure 1, the practical function that its tension-thining is processed partly is the smooth straight face of cylinder 101, makes the distortion of flange generation tension-thining by the extruding of the 101 pairs of flange inwalls in the face of cylinder.But the contact area of the punch of tension-thining and fin hole wall is large in process, and the hole inwall excessively turns black because rubbing easily, gently then causes product appearance bad, can form powdery granule at fin surface when serious.The transition face 102 of punch front portion is chamfering structure simultaneously, and corner angle partly have wearing and tearing after long-term the use.
Summary of the invention
The deficiency that the applicant is worn and torn easily for the existing equipment transition face that contact area is large, product appearance is relatively poor, punch is anterior in processing air-conditioner fin process, carry out Improvement, the punch of another kind of air-conditioner fin tension-thining is provided, can reduce the contact area of tension-thining punch and fin hole wall, stop the product surface blackout, reduce simultaneously the wearing and tearing of punch.
Technical scheme of the present invention is as follows:
A kind of punch of air-conditioner fin tension-thining, outer wall offers groove, and the junction of the circumferential and described groove of outer wall is with the circular arc protrusion.
Its further technical scheme is:
Described outer wall is with the twice groove, and the junction of the circumferential and described twice groove of outer wall is respectively with the circular arc protrusion;
The head of described punch and the transition face of described outer wall are circular arc.
Beneficial effect of the present invention is as follows:
Outer wall is offered groove, the junction of the circumferential and described groove of outer wall is with the circular arc protrusion, so just can reduce the contact area of tension-thining punch and air-conditioner fin hole wall, reduce the frictional heating of process, stop blackout, and can reduce stripping force, improve the crudy of air-conditioner fin; The wearing and tearing of process convex mould can also be reduced with the circular arc protrusion in the junction of the circumferential and described groove of the circular arc transition face of the head of punch and outer wall and outer wall, prolong die life.
Description of drawings
Fig. 1 is the front view of existing tension-thining punch.
Fig. 2 is front view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
As shown in Figure 2, outer wall of the present invention offers groove 3-1 and groove 3-2, and the junction of the circumferential and described twice groove of outer wall is with circular arc protrusion 4.The outer wall of punch is adding the effect that has guide-localization man-hour, will cause the tension-thining punch can not play the effect of guiding, location when the groove of offering is wide, thereby narrower near the groove 3-1 of tension-thining punch end, groove 3-2 is wider in another road, reduce groove to the impact of the guide-localization effect of punch, guarantee crudy; The groove of offering has reduced the contact area of tension-thining punch and fin hole wall, reduces the heating of process, stops blackout; Reduce simultaneously stripping force, improve the quality of products; The stress that the junction can be eliminated with the circular arc protrusion in the junction of the circumferential and described groove of outer wall is concentrated, and reduces punch wearing and tearing in use.
Nose of punch 1 passes through circular arc 2 transition with the transition face of described outer wall, so can reduce the wearing and tearing of process convex mould, prolongs die life.
Claims (3)
1. the punch of an air-conditioner fin tension-thining, it is characterized in that: outer wall offers groove, outer wall circumferentially with the junction of described groove with the circular arc protrusion.
2. the punch of air-conditioner fin tension-thining as claimed in claim 1 is characterized in that: described outer wall is with the twice groove, outer wall circumferentially with the junction of described twice groove respectively with the circular arc protrusion.
