Abstract
A cold extrusion technology for machining copper radiator includes machining die set, providing copper rod, installing said die set to extruding machine, and cold extrusion of said copper rod.
Description
Technical field
The invention belongs to a kind of processing technology thereof method of component of machine, be meant the copper core external diameter cold-extrusion technology method of heavy-duty rectifier spare radiator especially.
Background technology
Power rectifier device radiator copper core is a critical component of radiator, when processing and fabricating radiator copper core, all is to adopt the technological method for processing of solid bar truck processing external diameter to the size that requires generally, and blank dimension is greater than part nominal dimension 4-5mm.Lathe clamping copper core end face is 3mm, because the copper product plastic property is good, Vehicle Processing is under the situation of running up; The time have workpiece to fly out, the knot security bring hidden danger.And because processing dimension is excessive, (φ 70 * 54.5, and φ 80 * 74.5) utilization rate of raw materials is 78.9%-84% only, and waste of material is big, technology cost height.And must change head-clamp when adopting the Vehicle Processing external diameter to the technological method for processing of the size that requires tightly could the whole outer surface car is good, when turning around car, very easily produce seam and influence the performance of product.So necessary this is improved.By retrieval to domestic patent documentation, has only on September 8th, 1999, publication number is that 2337677 patent documentation discloses " a kind of power semiconductor radiator ", but this document only is described from the structure of power semiconductor with radiator, still finds no the report about power rectifier device radiator copper core processing technology aspect.
Summary of the invention
The objective of the invention is to, at the deficiency of existing processing and fabricating radiator copper core technology, it is simpler to propose a kind of processing technology, effective, no seam, and the new copper radiator processing technology thereof method of saving material.
According to implementer's case that purpose of the present invention proposed be: adopt cold-extrusion technology to replace former Vehicle Processing technology, make extrusion die according to radiator copper core is outer through desired size, extrusion die is installed on the conventional extruder, will be a bit larger tham the outer copper rod material of radiator copper core then and directly squeezes out required radiator copper core by extruder and extrusion die through the 0.2-0.8 millimeter.
By the exploratory experiment of repeated multiple times, trial production, test data, it is feasible adopting cold extrusion to replace former Vehicle Processing technology, adopts extrusion process can make utilization rate of raw materials rise to 93.3%, 95.9%.And push the seam that the radiator copper core that comes out no longer includes Vehicle Processing, and also no longer include turning processing lines, therefore to improving the thermal conductivity of product, the thermal resistance that reduces thermal diffusivity has good effect.And have following advantages:
1, productivity ratio, security raising, labour intensity descend
Existing 1.5 minutes/part of cold extrusion, 15 minutes/part of former Vehicle Processing, the worker improves several times.
Former rough turned piece easily flies out, and has now deducted rough turn technology, has therefore improved security.
2, stock utilization improves, and has reduced production cost
Push no copper scale, stock utilization is than former raising 11.9%--14%.
According to two kinds of products: copper core ZS179A-31-01, copper core ZS392-100-211 analyze.
One, former blank blank size φ 70 * 54.5+0.5 φ 80 * 74.5+0.5
Bad weight of hair is respectively 1.87Kg 3.34Kg
Two, improve back blank blank size φ 64.5 * 54+0.5 φ 75.5 * 74+0.5
Bad weight fraction of hair is 1.57Kg 2.96Kg in addition
Three, cost of raw material contrast
1.87Kg--1.57Kg=0.3Kg 0.3Kg * 36 yuan=10.8 yuan/kg
3.34Kg-2.96Kg=0.38Kg 0.38Kg * 36 yuan=13.68 yuan/Kg
Four, save production cost respectively 10.8 yuan/part, 13.68 yuan/part
3, thermal resistance value test data: (6m/S)
127 * 127 specification thermal resistance value≤0.037～0.047 ℃/W (design load) measured value is 0.0405 ℃/W
145 * 145 specification thermal resistance value≤0.035～0.045 ℃/W (design load) measured value is 0.038 ℃/W
168 * 168 specification thermal resistance value≤0.033 ℃/W (design load) measured value is 0.0318 ℃/W
Above data declaration copper core cold-extrusion technology from material property, crystalline phase, be worked into welding, quality, productivity ratio, labour intensity, economic production work and the every index that all helps reality than rate, safety analysis meets Design Requirement Drawing, possessed production specifications at present.
