The utility model completes preparation of three-compound rivet contact which automatically completes copper silver and silver alloy materials, and production efficiency and utilization rate of materials are high.

Description

The three composite rivet contact cold headers

Technical field

Utility model relates to a kind of cold headers, refers in particular to a kind of three composite rivet contact cold headers that manufactured copper covers silver and silver alloy three composite rivet contact that are used for.

Technical background

For saving rare precious metals (silver) resource, part had begun to adopt three composite rivet contact already with bank.At present, known three composite rivet type contact production technology is: be that the two compound cold headers of 30 types are produced two joint products by two composite rivet contact machines earlier, again by manually with silver and silver alloy flat sheet welded on the plane of rivet foot, finish the production of three composite rivet contact product.But there are 3 deficiencies in the preparation method that this copper covers silver and silver alloy three composite rivet contact: (1) artificial welding efficiency is low; (2) silver and silver alloy plain film adopt the sheet metal blanking moulding usually, and its lumber recovery is extremely low, have influenced the contact rate of finished products greatly; When (3) manually welding, the easy cross flow of scolder influences the contact electrical property of product to the working face of product.

The utility model content

For overcoming the above-mentioned defective that prior art exists, the utility model provides a kind of three composite rivet contact cold headers, and it can the disposable three composite rivet contact preparation work that copper covers silver and silver alloy, production efficiency and the stock utilization height finished automatically.

For achieving the above object, the technical solution adopted in the utility model is: a kind of three composite rivet contact cold headers, it comprises the two compound cold headers of 30 types, the two compound cold headers of this 30 type are mainly received box by slubbing mould pin, left-cut tool, quiet mould bases, left avertence core barrel, bed die, bed die pin, right avertence core barrel, right-cut tool, funnel, product collection and are constituted, in a side of bed die a newly-increased eccentric pipe and the newly-increased wire-sending device of a cover are set, make the S guide rail of the two compound cold headers of 30 types into three rank guide rails.

The utility model is by the improvement to the two compound cold headers of 30 types, realize that wherein one shears the process of two sections materials to cutting knife, wherein one cutter sheared two sections material, beat in the process in system, by adjusting the position of bed die pin, three sections material upsetting distortion in bed die, it is as follows to make the process of beating: right-cut tool is sheared the copper material, move to silver-colored line position, the silver line is sent into right-cut tool by newly-increased wire-sending device and is sheared, filamentary silver is sent into left-cut tool by newly-increased wire-sending device and is sheared, left-cut tool and right-cut tool move to the bed die center simultaneously and pause, three sections material left-cut tool and right-cut tool being sheared by slubbing mould pin head in the bed die hole, and jumping-up distortion in the bed die hole, left-cut tool, right-cut tool and slubbing mould pin are reset to initial position, it is contact foot desired location that the three compound charge bars that the bed die pin will be laminated with are delivered to the bed die front end, the upsetting of part material is shaped to the three composite rivet nose shape outside the bed die hole, at last, finish head part by the bed die pin, three composite contacts that moulding is finished eject bed die, fall into the product collection naturally through funnel and receive in the box.

The utility model utilizes the two compound cold headers of existing 30 types, and it is done necessary improvement, just can disposablely finish the three composite rivet contact preparation work that copper covers silver and silver alloy automatically.Three sections material upsetting distortion in bed die improve the bond strength that silver is covered in contact foot.The good effect of this method is: the production cycle of having improved stock utilization and shortening three composite contacts; The rate of finished products that drops into material reaches more than 80%, and production efficiency is at 3000/hour～5000/hour.
