Abstract
The utility model relates to a fine punching device for thin materials, which comprises a punching die and a punching head. The fine punching device is characterized in that the punching die is an elliptical groove, the punching head is an elliptical lug, at least one oil penetrating hole is arranged on the end surface of the punching head, and the oil penetrating hole is connected with an oil conveying pipe. Three oil penetrating holes are arranged on the end surface of the punching head of the fine punching device for thin materials. The utility model has the advantages that under the condition of small fit tolerance, the pulling and damaging force for ultrathin aluminum alloy sheets which are punched can be greatly reduced in the punching process to ensure the forming quality when pipe penetrating holes are punched by the ultrathin aluminum alloy sheets.
Description
Technical field
The utility model relates to a kind of decompressor, particularly a kind of precision stamping device that is used for thin material.
Background technology
At present during the radiating fin in producing refrigerating machine, need make the coil pipe hole in the radiating fin upper punch, in order to guarantee the radiating effect of radiating fin, the coil pipe hole of radiating fin must be met certain tolerance with cooperating of coil pipe, the big conjugation reduction of radiating fin with coil pipe, form a thermal resistance, influence the distributing of heat of medium in the coil pipe, little then in process of production coil pipe in perforation procedure, can't finish smoothly, also the radiating fin top disorderly may be damaged, former pipe perforation is general than being easier to punching out.But now in order to improve the efficient of heat radiation, adopted the coil pipe of some special pipes, as flat tube, elliptical tube, in order to finish flat tube, the perforation of elliptical tube, the requirement of the dimensional accuracy in punching press poling hole is higher on radiating fin, because radiating fin is ultra-thin aluminum alloy sheet, for guaranteeing the dimensional accuracy of punching press, tolerance fit between its male and female drift is very little, when utilizing existing drift on the radiating fin that thin material is made, to carry out punching press, easily draw the damage radiating fin when the punching press greatly, thereby can't finish the required precision of above-mentioned size because of relative frictional force.
Summary of the invention
The purpose of this utility model is to solve in the prior art to adopt the existing damage problem of drawing in the poling hole of the very little decompressor of tolerance fit on punching out ultra-thin aluminum alloy sheet for the dimensional accuracy that guarantees punching press, and a kind of precision stamping device that is used for thin material is provided.A kind of precision stamping device that is used for thin material of the utility model design, comprise punch die, staking punch, it is characterized in that: punch die is oval indent deep gouge, and staking punch is an oval plush copper, have an oil seepage hole on the end face of staking punch at least, oil seepage hole connects a petroleum pipeline.Oil seepage hole on the end face of staking punch has three.The utility model has the advantages that under the very little situation of tolerance fit, in the time of reducing punching press significantly to the ultra-thin aluminum alloy sheet that is stamped draw damage power, guarantee the forming quality of ultra-thin aluminum alloy sheet when punching press poling hole.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
The specific embodiment
Comprise punch die 1, staking punch 2 among the figure, it is characterized in that: punch die 1 is oval indent deep gouge, and staking punch 2 is an oval plush copper, has an oil seepage hole 3 on the end face of staking punch 2 at least, and oil seepage hole 3 connects a petroleum pipeline 4.Oil seepage hole 3 on the end face of staking punch 2 has three.
In process of production, can be according to the material property of the aluminum alloy flake of punching press, the number and the oil impregnate amount of design oil seepage hole 3, when 2 pairs of the staking punch of the punch die 1 of the very little oval indent deep gouge of tolerance fit and oval plush copper are pressed, aluminum alloy flake is sandwiched in wherein, because the speed that moves up and down of staking punch 2 is very fast, and tolerance fit is less, then easily aluminum alloy flake is produced and draw damage, if there is lubricating oil to be exuded to staking punch 2 surfaces from oil seepage hole 3, then can reduce significantly staking punch 2 move up and down in to the aluminum alloy flake punch-out draw damage power, can guarantee stamping quality.
Claims (2)
1, a kind of precision stamping device that is used for thin material comprises punch die, staking punch, it is characterized in that: punch die is oval indent deep gouge, and staking punch is an oval plush copper, has an oil seepage hole on the end face of staking punch at least, and oil seepage hole connects a petroleum pipeline.
2, by the described a kind of precision stamping device that is used for thin material of claim 1, it is characterized in that: the oil seepage hole on the end face of staking punch has three.
