Description

Conduit connection terminal one-time-shaped mould

Technical field

The utility model belongs to a kind of mould, is specially a kind of conduit connection terminal one-time-shaped mould.

Background technology

The manufacture process of conduit connection terminal is divided into punching, cut limit, the operation such as take all of, in above-mentioned process, due to the backwardness of mould, make in process some operation need workman manually to complete or many moulds of needs could be realized, make the low and quality of production efficiency be difficult to ensure, add the research that lacks relation between the each modular construction of pair of wire connection terminals and overall performance, make the overall quality of binding post fail to increase always.Traditional conduit connection terminal is in the time making, generally that copper sheet is put into mould through punching press for several times, be washed into a planar shaped basic material with square pin, and then by artificial, the copper sheet of going out is carried out to further bending, make its one end be closed into cylinder, the other end is half-open circle, this processing mode needs extensive work to carry out curved circle and finishing is processed, and operating efficiency is very low.

Utility model content

The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, easy to operate, conduit connection terminal one-time-shaped mould that can disposal molding.

In order to achieve the above object, the technical scheme adopting is: a kind of conduit connection terminal one-time-shaped mould, and the combination die that it comprises multiple upper die and lower die, patrix entirety is punch, counterdie entirety is die; Combination die is provided with locating hole module, uropore module, side module, square pin module, trailing edge module, muscle line module, upper semi-circle module, lower half circle module, blanking module and waste material module successively by charging order; The mid point of side module and the adjacent module 1.5 times of workpiece distances of being separated by.

Locating hole module, uropore module, side module and trailing edge module are plane knife edge die, cut away the waste material just as upper male mould after matched moulds.

Side's pin module is the square-foot shaping mould of three cut-outs, and square-foot direction is downward.

Muscle line module is muscle line extrusion forming mold.

Upper semi-circle module and lower half circle module are bending and forming die.

Blanking module is knife edge die, cuts material for workpiece finished product.

Waste material module is knife edge die, and clout is cut.

Adopt the beneficial effect of technique scheme to be: this conduit connection terminal one-time-shaped mould is by inner multiple combination dies, by charging by first locating, cut off again, the step of last moulding, wherein side module single stepping has completed the side processing of adjacent two workpiece, the operations such as the multi-section mould that conventional art is needed, artificial revolving die and artificial brake forming once complete, and have greatly reduced processing cost and process-cycle; The shortcoming such as workpiece size deviation, the machining accuracy of having avoided revolving die and cause are low.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is explained.

Conduit connection terminal one-time-shaped mould, the combination die that it comprises multiple upper die and lower die, patrix entirety is punch, counterdie entirety is die; Combination die is provided with locating hole module 1, uropore module 2, side module 3, square pin module 4, trailing edge module 5, muscle line module 6, upper semi-circle module 7, lower half circle module 8, blanking module 9 and waste material module 10 successively by charging order; Side module 3 and the mid point of the adjacent module 1.5 times of workpiece distances of being separated by.The setting of side module 3 has taken into full account the symmetry of processing work, and the cut-out size of waste material, and the side that single stepping has completed adjacent two workpiece cuts off, and has promoted working (machining) efficiency.

Wherein locating hole module 1, uropore module 2, side module 3 and trailing edge module 5 are plane knife edge die, cut away the waste material just as upper male mould after matched moulds.First charging positions hole punching press, facilitates follow-up matched moulds link to add the accuracy to size of labor and materials, is secondly uropore punching press and side punching press; Side punching press scope is large, intensity is high, and is knife edge die, is applicable to being configured in the front stage casing of mould, and too forward charging precision is inadequate, after leaning on very much, can affect other profiled part.

The side's of being pin module 4 after side module 3, square pin module 4 is the square-foot shaping mould of three cut-outs, and square-foot direction is downward, and therefore the module after square pin module 4 is required to be the reserved tapping channel of sagging square pin; Be trailing edge module 5 more afterwards, now first one-step forming of workpiece, should not remake rupturing operation to workpiece afterwards again;

Muscle line module 6, upper semi-circle module 7 and lower half circle module 8 after side's pin module 4 are all shaping moulds, and wherein muscle line module 6 is muscle line extrusion forming mold, and upper semi-circle module 7 and lower half circle module 8 are bending and forming die; Geometric molding mould is mainly the shape of shaping workpiece, therefore need to after cutting workpiece operation, carry out.Upper semi-circle module 7 is inverted " U " shape radius bend mould, and before its workpiece, tail end half circular diameter that is shaped is inconsistent, needs prearrangement of deformation amount scope between the mould of the front and back of change in radius, otherwise workpiece easily damages while being bent; The patrix of lower half circle module 8 is the same with upper semi-circle module 7, and it is just in time contrary that its counterdie and patrix close, and be circle in the middle of after matched moulds; As larger in workpiece size, casing buckling shaping mould intermediate demand adds core rod.

Moulding of workpiece after lower half circle module 8, blanking module 9 afterwards, waste material module 10 are all knife edge dies, and blanking module 9 cuts material for workpiece finished product, and waste material module 10 cuts off clout to be convenient to process.

This conduit connection terminal one-time-shaped mould, need to use step-by-step movement feeder, and each matched moulds feed length is a width of the workpiece, feeding when parting, stops feeding when matched moulds, after progressive die through matched moulds straight forming repeatedly, improving product working (machining) efficiency, has saved processing cost.
