Abstract
The invention discloses a precision bending die for power terminals. The precision bending die comprises an upper die and a lower die corresponding to the upper die, a first bending gap, a second bending gap and a bending retaining gap are further arranged between the upper die and the lower die and are sequentially arrayed, the first bending gap is used for primarily bending a product portion to be bent, the second bending gap is used for secondarily bending the bent product portion, and the bending retaining gap is used for retaining the shape of the portion after the portion is secondarily bent. The precision bending die has the technical advantages that a product is finally bent and formed by two separate procedures, a bending process is simple, a bent area cannot rebound easily or deform by a positioning and retaining effect of a retaining area, and precision of doubly bent legs of the bent area, precision between the two legs and precision between two contacts are effectively controlled.
Description
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of precision voltage source terminal Bending Mould.
Background technology
Technology of die manufacturing is the basis of modernized mould industry development; Have moulding fast, can realize batch machining; Machining accuracy is guaranteed, and wherein Bending Mould is meant in cold stamping processing, metal or nonmetallic materials is processed into a kind of special process equipment of part.Bending (Bending) metal blank at first passes through strain under the pressure of bender patrix or counterdie, get into plastic deformation then; In the incipient stage of plastic bending, plate is a free bend, along with patrix or counterdie exerting pressure to plate; Plate and counterdie V-type groove inner surface are close to gradually; Radius of curvature and bending moment arm also diminish gradually simultaneously, continue pressurization and stop up to stroke, make upper and lower mould and sheet material be close to full the contact at 3.
Power supply terminal is a kind of wiring terminal terminal; Single hole, diplopore, socket are arranged, the branch of hook, and existing power supply terminal member; In the course of processing, require between two bending legs, bipod, better precision of control between two contacts; Existing all is to adopt numerous and diverse work flow, and in the process of washing off, is difficult to guarantee higher precision, therefore requires bigger to Mould design.
Summary of the invention
Technical problem to be solved by this invention provides power supply terminal Bending Mould accurate between simple, easy to control flex area two bending legs of a kind of bending technique, bipod, between two contacts.
To achieve these goals, the invention provides a kind of precision voltage source terminal Bending Mould, comprise patrix and the counterdie corresponding, also be provided with between said patrix and the counterdie and be used for the product bending part is carried out between first bending of a bending with patrix;
Be used for and carry out between second bending of secondary bending at the position after the bending between first bending;
And be used for the position shape after the secondary bending is carried out between the bending maintenance of shape maintenance;
Be arranged in order between said first bending, between second bending and between the bending maintenance.
Above-mentioned precision voltage source terminal Bending Mould, preferred, comprise between said first bending being used for the product bending part, be bent into one less than 90 ° of angles first on bending projection and first time bending projection.
Above-mentioned precision voltage source terminal Bending Mould, preferred, comprise between said second bending being used for the product bending part, be bent into one equal 180 ° of angles second on bending projection and second time bending projection.
Above-mentioned precision voltage source terminal Bending Mould, preferred, between keeping, institute's bending comprises being used for fixing the going up of keeping in product bending part kept projection and keep projection down.
Technique effect of the present invention is: through being divided into secondary with the final bending and molding of product; Bending technique is simple; Through keeping the district to keep, make flex area be difficult for resilience and distortion at last, effectively controlled precision between two bending legs, bipod of flex area, between two contacts.

Embodiment
Below, in conjunction with accompanying drawing the present invention is done further explanation.
Shown in Fig. 1-3; The present invention provides and the invention provides a kind of precision voltage source terminal Bending Mould; Comprise patrix and the counterdie corresponding with patrix; Also be provided with between first bending between said patrix and the counterdie, between second bending and between the bending maintenance, be arranged in order between said first bending, between second bending and between the bending maintenance, be used between said first bending bending is carried out in the product bending part; Be used for the secondary bending is carried out at the position after bending between first bending between said second bending, be used between said bending keeps that the position shape after the secondary bending is carried out shape and keep; Comprise bending projection 1 and first time bending projection 2 on first between said first bending, bending projection 1 and first time bending projection 2 are bent into one less than 90 ° angle with the product bending part on said first; Comprise bending projection 3 and second time bending projection 4 on second between said second bending, on said second bending projection 3 and first time bending projection 4 with the product bending part, be bent into one equal 180 ° the angle; Comprise between institute's bending maintenance keeping projection 5 and the following projection 6 that keeps, said upward maintenance projection 5 is fixed maintenance with the following projection 6 that keeps with the product bending part.
In product Bending Processing process; Through bending projection 1 in first between first bending and first time bending projection 2 bending part is bent into one less than 90 ° angle; Could the bending part be bent into an angle that equals 180 ° through bending projection 3 in second between second bending and second time bending projection 4 like this; The product that keeps projection 5 and keep projection 6 will be bent into 180 ° down of going up between keeping through bending at last positions maintenance; Make flex area not yielding, effectively control precision between two bending legs, bipod of flex area, between two contacts, at last through the power supply electronic that processes referring to shown in Figure 4.
Though oneself discloses the present invention as above with preferred embodiment, the present invention is defined in this.Any those skilled in the art are not breaking away from the spirit and scope of the present invention, all can do various changes and modification, so protection scope of the present invention should be as the criterion with claim institute restricted portion.
