Description

High fin section bar radiating piece cut the punch die tool

Technical field

The utility model relates to a kind of diel in the forming materials field, relate in particular to a kind of in type high fin section bar radiating piece, carry out punching or breach cut the punch die tool.

Background technology

In electronic apparatus,, usually these heater elements are installed on the metallic matrix, to increase its heat-sinking capability for strengthening the heat-sinking capability of heater element.The aluminium section bar radiating piece is generally use in this type of heat radiation part a kind of.For the demand of producing in enormous quantities, hole in this kind part or breach etc. all utilize the mode of mould punching press to process.This radiating piece mainly fin by wherein dispels the heat, and along with the increasing of the integrated degree of electronics, the caloric value of electronic component also strengthens thereupon in the circuit, for improving the heat-sinking capability of this radiating piece, the height of its fin is also being increased, and particularly when fin height during greater than 25 millimeters, adds man-hour with common diel, cause the fin part in the radiating piece can't cut off easily, and the finished product after the punching press also can't take out from mould because of flexural deformation.

The utility model content

The technical problem that the utility model solved is: provide a kind of be difficult for making the diastrophic high fin section bar radiating piece of fin cut the punch die tool.

The technical scheme that solves the problems of the technologies described above is: high fin section bar radiating piece cut the punch die tool, comprise punch and die, wherein, on die, be positioned to cut and dash the zone correspondence and be provided with the supporting construction that contacts cooperation with the sidewall of fin.

Further be that described supporting construction contacts cooperation with the sidewall of fin when the mould matched moulds.

Further be that described supporting construction adopts and the suitable support slot of fin shape size.

Further being, is anisopleual matched in clearance between fin and the support slot during mould matched moulds, and wherein a side is that the zero clearance cooperates.

Further be to be provided with angle between the bottom surface of punch and the land area.

Further be, on die, be positioned to cut and dash the support slot of stepping down that correspondence is provided with and the fin shape size is suitable outside the zone that stepping down during the mould matched moulds between support slot and the fin is matched in clearance.

The beneficial effects of the utility model are: adopt above-mentioned supporting construction can prevent the flexural deformation of fin; This mould simple in structure can directly be carried out local modification on existing mold, be applicable to cutting of various section bar heat radiation parts dashed processing.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described further.

As Fig. 1～Fig. 4, high fin section bar radiating piece of the present utility model cut the punch die tool, comprise punch 1 and die 2, wherein, on die 2, be positioned to cut and dash zone 4 correspondences and be provided with the supporting construction that contacts cooperation with the sidewall of fin 3.Above-mentioned cutting dashed zone 4 as shown in figs. 1 and 4, and its fin of containing 3 quantity decide according to the arranging density and punch 1 edge width of actual fin 3, and punch 1 edge width decides according to the design size of hole on the product or breach.Owing to cause the process of fin 3 flexural deformations at matched moulds, promptly partly begin to act on the radiating piece to punch 1 and die 2 relative these static processes, guarantee preferably that therefore supporting construction only contacts cooperation with the sidewall of fin 3 when the mould matched moulds from the cutting edge of punch 1.Like this, put into mould and position at mould at high fin section bar radiating piece, and cut and dash in the process of taking out from mould later, supporting construction and fin 3 are noncontacts, thereby are convenient to fast fin 3 be placed and extracted.

For simplified structure, be convenient to the manufacturing of mould, described supporting construction adopts and the suitable support slot 6 of fin 3 shapes size.Support slot 6 can be by being formed by the mold insert assembly unit, also can be directly on part by processing as machining modes such as line cuttings.During matched moulds, the cell wall of support slot 6 contacts cooperation with fin 3, thereby plays the supporting role to fin 3.Support slot 6 has in fact also played the effect of location to high fin section bar radiating piece, avoid designing on die 2 too much location structure such as alignment pin and location-plate etc. so again, has therefore played the effect of simplified structure.

In order to carry out the production of radiating piece by this mould of high efficiency utilization, require high fin section bar radiating piece can put into mould and location fast, cut to dash and can also from mould, take out fast later on.As described above, cause fin 3 flexural deformations, guarantee when therefore being preferably in the mould matched moulds to be anisopleual matched in clearance between fin 3 and the support slot 6, and wherein a side is that the zero clearance cooperates in the matched moulds process.Like this, in fact fin 3 cooperates with the side contacts that 6 of support slots cooperate in the zero clearance, and opposite side is provided with the gap.Like this, just can easily fin 3 be put into support slot 6 or take out from support slot 6.

In order in the matched moulds process, to make fin 3 contact cooperation, can adopt multiple mode with the cell wall of support slot 6 one sides.Such as, a side slide block mechanism can be set in mould, this slide block structure is formed by the slide block spare that is arranged in die 2 and with the punch 1 homodromous piece of carving, and carves and adopts the inclined-plane to be slidingly matched between piece and the slide block spare.In the matched moulds process, carve that piece descends and contact, and promote the vertical and matched moulds direction of slide block spare by the inclined-plane and move, thereby promotion fin 3 contacts with the cell wall of a side of support slot 6 with slide block spare.Above-mentioned side slide block mechanism structure more complicated as the scheme of another kind of simple possible, can will be provided with included angle between the bottom surface of punch 1 and the land area 7, and die face 7 is obliquely installed even punch 1 bottom surface is involutory.Because punch 1 is perpendicular to land area 7 motions during matched moulds, after between the bottom surface of punch 1 and the land area 7 included angle being set, punch 1 cutting edge to fin 3 can produce one with the perpendicular component of matched moulds direction, thereby make fin 3 contact cooperation with the cell wall of a side of support slot 6.

In die 2 location is installed for the ease of high fin section bar radiating piece, is positioned to cut on die 2 and dashes the support slot 5 of stepping down that correspondence is provided with and fin 3 shapes size is suitable outside the zone 4, stepping down during the mould matched moulds between support slot 5 and the fin 3 is matched in clearance.Position support slot 5 can play a supportive role to radiating piece on the matched moulds direction.

Embodiment

The high fin section bar radiating piece of a television set integrated package, long 130mm, wide 75mm, fin 3 highly are 32mm, die-cut 24.5mm on this part is wide for need, the breach that 15mm is dark.At the punch 1 and the die 2 of diel employing upper and lower settings, wherein the bottom surface of punch 1 becomes 6 ° of angles with horizontal plane; On die 2, lay respectively to cut and dash the support slot 6 that corresponding fins 3 are disposed with and fin 3 shapes size is suitable inside and outside the zone 4 and the support slot 5 of stepping down.This mould is when matched moulds, and fin 3 is close to the same side cell wall of support slot 6, and its gap is zero; Another side cell wall and fin 3 keep the gap width of 0.4mm; The both sides cell wall of support slot 5 of stepping down all keeps 0.2～0.5mm gap with fin 3.This mould work in-process has been obtained satisfied effect.
