Embodiment
Present embodiment is the utility model preferred implementation, and other all its principles are identical with present embodiment or approximate with basic structure, all within the utility model protection range.
The utility model mainly comprises head 1 and the afterbody that links together, in the present embodiment, head 1 cross section is annular, the afterbody cross section is waist shape, in the present embodiment, afterbody comprises two first contact planes 2 that are arranged in parallel and two second contact planes 3, second contact plane 3 is outwards outstanding arc, the roughness of first contact plane 2 and second contact plane 3 is below Ra1.6, afterbody has two screwed holes 4, and in the present embodiment, two screwed holes 4 are through hole, two screwed holes 4 are opened on first contact plane 2, and head 1 and afterbody connecting portion have fabrication hole 5.
The course of processing of the present utility model comprises following part:
1, cold extrusion: the utility model adopts the copper rod of Φ 6.8 as base-material, utilize cold-extrusion technology that the afterbody of copper rod is squeezed into the tail shape identical with the tail shape of the utility model finished product, be about to the afterbody extrusion modling, form primary blank, the head 1 of primary blank remains the copper rod of Φ 6.8;
2, pier is thick: the head 1 to primary blank applies axial pressure, makes its head 1 diameter chap, forms secondary blank, and head 1 diameter of secondary blank is more than or equal to head 1 diameter of finished product;
3, turning, endoporus: turning processing is carried out in head 1 outside of secondary blank, head 1 car of secondary blank is become and the identical cylinder of finished product head 1 diameter, and head 1 inner car is gone out the endoporus identical with finished product, endoporus machine-shaping soon;
4, bore fabrication hole 5: get out fabrication hole 5 in head 1 and afterbody junction;
5, end face milling: the end face of head 1 and afterbody and two first contact planes 2 of afterbody are carried out finish-milling processing, because two first contact planes 2;
6, towards thread Pilot hole: thread Pilot hole is gone out in screwed hole 4 positions at afterbody;
7, bottom outlet deburring: the burr at bottom outlet edge is removed;
8, tapping: process screw thread in the thread Pilot hole inboard, form screwed hole 4;
9, shake grinding and polishing light: semi-finished product are put into special-purpose shake grinding machine, utilize abrasive material stone vibration friction that the piece surface burr is removed.
10, fine finishining: utilize the manual burr of removing fabrication hole 5 the inners, promptly form finished product.
Electric connector contact requires two plane roughness of afterbody all to require to reach Ra1.6, general Milling Process all can stay clearly tool marks at product surface, precision can't reach Ra1.6, need finish-milling processing just can reach, and Milling Process can produce burr at the periphery of product surface, excessive burr can cause the contact between the contact unreliable, it is big that contact resistance becomes, when bigger electric current passes through contact, can produce bigger heat, performance to electric connector will have a negative impact, and need increase one procedure in the back and remove the wedge angle burr.For the utility model can adopt cold-extrusion technology processing, several procedures of traditional diamond-making technique are integrated into one procedure, just can be by one cold-extrusion shaping operation with two contact plane processed, and can improve the precision of contact surfaces effectively and prevent the generation of corner burr.The processing of employing cold-extrusion technology, make contact can obtain desirable surface roughness and dimensional accuracy, cold extrusion processing back part precision can reach the IT7-IT8 level, surface roughness can reach Ra0.2-Ra0.6, its precision is directly by the decision of the precision of mould, thereby avoided the influence of the technical merit of operative employee in the cutting process to the product precision.
Because the maximum cylindrical of general electric connector contact is Φ 9.5, adopt the electric connector contact of traditional handicraft processing, need copper rod blanking with Φ 10.0, carry out cut then, the utilance of material is lower, is generally 40.3%, and the utility model can adopt cold extrusion processing, only need process with the copper rod of Φ 6.8, the utilance of material can reach about 80%.The utility model adopts cold extrusion processing, is to utilize the plastic flowing of material and obtain required shape and size, has avoided a large amount of cut, has greatly only reduced raw-material waste.
Manufacturing procedure of the present utility model is less, use equipment is also few, thereby avoided traditional electric connector contact in the course of processing, to need frequently to change process equipment, frequent clamping location, workman's the amount of labour is bigger, and add building site stability and also be difficult to guarantee, be difficult to realize the problem of automated production, the utility model can adopt cold-extrusion technology processing, reduce cutting output significantly, and clamping times can reduce thereupon also, working strength of workers alleviates greatly, realize automated production easily, production efficiency is than high several times of common process.
