Summary of the invention
The applicant, for above-mentioned existing issue, is studied improvement, and the Forging Technology of a kind of electrical equipment support is provided, and not only makes presentation quality, service property (quality) meet user demand, and has simplified production and processing technology, has reduced cost of manufacture.
The technical solution adopted in the present invention is as follows:
A Forging Technology for support for electrical equipment, its forging step is as follows:
The first step: get the raw materials ready: offer extrusion die according to electrical equipment by the shape of support, and utilize extrusion die extruding to form blank;
Second step: blanking: sawing blank is to length 36-37.5mm, width 158 ± 0.5mm;
The 3rd step: heating and thermal insulation: section bar is heated to 460 ± 10 DEG C from room temperature with 30～40min, insulation 30～45min;
The 4th step: bending: section bar described in above-mentioned the 3rd step is passed through to bender bending;
The 5th step: polishing is repaired: the blank after utilizing polissoir to bending carries out sanding and polishing;
The 6th step: post bake: blank is heated to 460 ± 10 DEG C from room temperature with 30～35min, insulation 30～40min;
The 7th step: forging mold preheating: forging mold is preheated to 150 °～200 DEG C with 30min～60min;
The 8th step: finish-forging: in the time that blank drops to 380～460 DEG C at room temperature, blank is put into 400 tons of forging molds under double helix friction press, forge one-shot forming and form forging;
The 9th step: trimming: utilize 80 tons of open type punch press that unnecessary forging overlap is removed in edger.
The tenth step: solid solution: the forging after described trimming is put into the material frame that quenches, by suspender, the quenching material frame with forging is put into glowing furnace, 530 ± 5 DEG C of molten design temperatures, temperature retention time is 3～5h, insulation finish after by the quenching material frame with forging put into water tank carry out cooling fast, until forging hangs out after being cooled to room temperature;
The 11 step: timeliness: by the tenth step quench after forging together with quench material frame put into aging furnace, heating-up temperature is 170 ± 5 DEG C, temperature retention time 8～10h, insulation finish after by the quenching material frame with forging hang out and air cooling to room temperature;
The 12 step: machined and subsequent treatment: utilize CNC by the 11 step gained forging process to drawing requirement; And forging is carried out to polishing, plating on request.
Beneficial effect of the present invention is as follows:
(1) at electrical equipment with having replaced original casting technique by aluminum alloy forged technique in the manufacture process of support, reduce the possibility that it produces defect in manufacture process, the performance of electrical equipment support is greatly improved, electrical equipment at outer surface dense structure, smooth, pore-free after forging, avoids occurring the problems such as tissue looseness, pore, roughness be poor with support raw material in the past.
(2) in the manufacture that can realize electrical equipment support in the manufacture process of support by a secondary mould, post bake for electrical equipment, greatly shortened product process-cycle, reduced production cost, and the product mechanical property after forging doubles than cast article, meets routine use demand.
