Abstract
The modified drift has wear-resistant characteristic, and twice are towards sword (20,21) before and after being characterized in having on the front end (13) of body (11), and the centre is separated by an annular groove (23), and the diameter of back blast blade (21) is slightly less than preshoot sword (20).
Description
The present invention a kind ofly carries out cold worked metal-working punch to metal, especially a kind of modified drift of prolonging life tools of being suitable for.
As everyone knows, the cold working of metal can be finished by punching press or perforation, with drift or similar tool metal is axially cut, and drift passes metal, and unwanted material is washed out.This process and instrument are of many uses, for example can be with thick towards processing nut and other goods first.
Prior art discloses diversified drift.For example Briggs has just been showed a kind of drift in 295, No. 227 United States Patent (USP)s, and the curved of this drift increases gradually towards sword, like this, main drift, promptly Zui Xiao drift can make other part bendings of metal, by the sword that dashes of back it is washed out.
Fu Leite has also showed a kind of drift 2,522 in No. 440 United States Patent (USP)s, and this drift can once be finished perforation, fraising and polishing, and its each metal machined surface is arranged one by one, and each operation is finished one by one when cutter passes workpiece.Punching press not only is used for metal processing, also can be used for other field, and Acker is gloomy 3,143, has just talked about this point in No. 026 United States Patent (USP); Punching press also can be adopted rotation mode, and Johnson has set forth this point 4,273 in No. 015 United States Patent (USP).
Fraising technology also is important, and it is reciprocating to workpiece with cutter, and metal is washed out.1,318, No. 489 United States Patent (USP)s of the visible Donaldson of illustration of fraising technology and 1,441, No. 502 United States Patent (USP)s of Hooke.
Purpose of the present invention just is to solve some problems that run on the piercing process.
Punch press generally all has a drift, and with the drift alignment pieces and do axially-movable, drift just washes out metal in by workpiece.A problem that runs into is exactly that drift can produce wearing and tearing in the middle of using, so that can not finish predetermined work effectively.Will shut down the replacing drift this moment.Here, difficulty is conspicuous, at first run into be exactly downtime obviously very uneconomical, secondly, drift is relatively more expensive, frequent replacing can make the total cost of production of producer increase to some extent.
But it is found that and to design a kind of modified drift, can overcome the sort of " wearing and tearing " problem that often runs into of mentioning just now at least to a certain extent.
People also find, the life-span of this drift is than the long three-to-four-fold of common drift, but the continuous operation long period need not shut down the drift of changing wearing and tearing, reduced cost.
Therefore, purpose of the present invention just provides a kind of so follow-on long wearing punch.
In development process, it is found that,, just can prolong the actual life of drift greatly if design two at least towards sword at the front end of drift.If preshoot sword diameter is a bit larger tham back blast blade, after the wearing and tearing of preshoot sword work a period of time, back blast blade just can continue workpiece is carried out punching press, has therefore prolonged working life, has reduced and has shut down the time of changing drift, has reduced cost.
People find that also first road separates towards an available annular groove between the sword towards the sword and second road.Be coated with back-up coat on the drift, when drift wore and tore, back-up coat was peeled off sometimes.Is with annular groove when the back-up coat of preshoot sword is peeled off or damaged with the purpose that first road and second road separate towards sword, the unlikely back blast blade that passes to.
Certainly, know, use twice towards sword, be not limited in this, also can use the sword that dashes more than the twice although the present invention only mentions.
Therefore, it is exactly main purpose of the present invention that the modified long wearing punch with above-mentioned characteristic is provided, and can increase further understanding of the present invention referring to following brief description of drawings.
Fig. 1 is the side view of modified drift.
Fig. 2 is that the blade that dashes of modified drift divides the part side-looking enlarged drawing that disconnects.
Fig. 3 is the cutaway view along the 3-3 line of Fig. 2.
At first see Fig. 1, the modified drift of numeral shown in 10 is elongated cylinder, and front and back end 13,12 is relative, and main body is 11, and thicker part divides 14 against the rear end 12, and thin part 15 is against front end 13.
It should be noted that this drift uses on punch press usually, thicker part divides 14 to be fixed in a usual manner on the plunger holder of punch press, can change.Concrete condition is not here dilated, and is very familiar because be engaged in the common laborer of this technology for how this drift being fixed on the punch press.
See Fig. 1 and Fig. 2 again, can see on the front end 13 of drift 10 that preshoot sword 20 and back blast blade 21 are arranged.These twice are similar substantially towards sword, and its shape is same as the thicker part branch, and diameter is greater than 15 parts.Twice have inclined-plane 20a and 21a on sword, according to Fig. 2 and Fig. 3, be coated with back-up coat P on the inclined-plane, and whole drift 10 is made by high-speed steel S basically.
Preshoot sword 20 and back blast blade 21 are by annular groove 23 separately.As previously mentioned, be used for metal is washed out from workpiece towards sword 20, in the time of certain of working life, back-up coat P may be cracked or be peeled off.Annular groove 23 will towards sword 20 with separate towards sword 21, reduce the damage of preshoot sword.
The diameter of back blast blade 21 is less than preshoot sword 20, and yes prevents the damage or the wearing and tearing of back blast blade 21 for its purpose, up to preshoot sword 20 be worn can't use till.
When using the modified drift, it should be noted that thicker part divides 14 should be fixed on the anchor clamps of punch press, uses drift reciprocating on workpiece then, utilize punch die that metal is swept away.Work so repeatedly after certain number of times, preshoot sword 20 will be worn, and diameter will reduce, so that the work that can't be satisfied with.Do not need to carry out any change this moment, do not need to shut down yet.As long as continue workpiece is put into punch press, back blast blade 21 will be proceeded punching press.So neither need to shut down, also reduced the expense of changing drift.
It should be noted that not deviating from spirit of the present invention and not exceeding under the situation of scope of accessory claim, can improve drift.
For example, as previously mentioned, this drift is not restricted to former and later two towards sword, can have more towards sword.In general this drift is mainly used in stamped metal, but also can be useful for the punching press other materials.
Though it should be noted that in addition said preceding back blast blade all is a ring-type among the present invention,, also can adopt other structures according to the different requirements of press work.
