Description
Technical field
The utility model belongs to mould.
Background technology
The mode of static conductive rod is to adopt turning process in the existing processing vacuum switch tube, the blank that turning is used generally is a diameter than the part external diameter oxygen-free copper bar of big 3～4mm also, there is following deficiency: 1,, make waste of raw materials big because the waste material that turning is fallen is many; 2, during operating cost, production efficiency is low.
Summary of the invention
The purpose of this utility model provides a kind of extrusion molding dies that is used for processing the vacuum switch tube static conductive rod, can save material and reduces the operating time.
The utility model is achieved in that by upper die and lower die to be formed, said patrix comprises upper plate and is positioned at the upper padding plate of upper bolster, punch and retainer plate, wherein, upper padding plate is between upper plate and punch and retainer plate, the male cone (strobilus masculinus) of punch and the inner conical surface of retainer plate are interference fit, and be connected with upper bolster by nut, upper bolster is connected with upper plate by screw, said counterdie comprises lower shoe and the lower bolster that has centre bore, be positioned at the push rod of centre bore, be positioned at the upper cavity die and the lower cavity die of guard ring and following guard ring, and the jacking block that is positioned at lower cavity die, wherein, the inner conical surface of the male cone (strobilus masculinus) of upper cavity die and lower cavity die and last guard ring and following guard ring is all interference fit, push rod and jacking block are for being threaded, and last guard ring is connected with lower shoe by screw with following guard ring and lower bolster.
Above-mentioned lower surface of going up guard ring respectively is provided with the step of the identical size of a circle with the upper surface of following guard ring, and is with the centring ring that plays the role of positioning on these two steps.
The gap of said interference fit is-0.08～-0.12mm, the work fit clearance of said punch and upper cavity die is 0.05～0.08mm, the gap of said jacking block and lower cavity die is 0.08～0.10mm.
The utility model changes the processing mode that has static conductive rod in the vacuum switch tube now into extrusion forming process by turning process by adopting special extrusion molding dies, has the following advantages: the first, save material, and reduce cost of parts.In 50 yuan of oxygen-free copper bar market average prices, adopt extrusion forming process than adopting turning process and save copper material 1.2Kg/ spare (is that the static conductive rod of Φ 70 is an example with a kind of outside diameter), thereby reduce 60 yuan/part of cost of parts; The second, reduce workman's operating time, significantly increase work efficiency.Process a same part, but adopt one of about one minute extrusion molding of extrusion forming process, than save about 20 minutes with turning process.If one hour production cost is by 15 yuan of calculating, 5 yuan/part then can save production cost.Promptly adopt extrusion forming process to amount to and to reduce by 65 yuan/part of cost of parts.One secondary mould is in its working life in the phase, but an extrusion molding 3000-4000 part blank.And the cost of a secondary mould is much smaller than the production cost of saving.
