Abstract
Provided is a stamping process method for a revolving body metal extruded part refined blank. According to the method, the characteristics of the high efficiency of stamping equipment and the high precision of a mold are combined, the problems that a mechanic refined blank process is low in production efficiency and poor in blank manufacturing precision consistency are effectively solved, and the limitation that the precision of a traditional revolving body metal extruding refined blank part can be achieved only through a machining method is broken through; the application range is wider, no machining procedure exists in the whole production process, processing procedures are fewer, and the machining precision consistency is good; and the material utilization rate is high, and the stamping process method is suitable for machining the metal extruded part refined blank on a large scale.
Description
Technical field
The invention belongs to machining stamping technology field, particularly revolving body metal extrusion refines base Sheet Metal Forming Technology, is particularly useful for T-shaped revolving body metal extrusion and refines the cold extrusion shaped processing of base.
Background technology
Current revolving body metal extrusion is refined base and is mainly taked two kinds of machining mode, and the first is for large part, makes with bar size, cut-out, planar end surface, fine cylindrical; The second is for smallclothes, makes with deburring after steel wire cylindrical grinding, cut-out, the flat rear mill both ends of the surface of batch dress.It is minimum that first kind of way single-piece machine adds production efficiency; After second way clamping, to add production efficiency higher for batch machine, but should limit due to clamping size, process the wire stock of minor diameter only, narrower by scope, need repeatedly grinding in mill both ends of the surface, the uniformity of size is larger by the impact of clamping quality and grinding skin location basal plane.
Summary of the invention
Object of the present invention is exactly the deficiency in order to overcome above-mentioned background technology, provides a kind of revolving body metal extrusion to refine base Sheet Metal Forming Technology method.
Revolving body metal extrusion of the present invention refines base Sheet Metal Forming Technology method, and its step is as follows:
1) blanking
Forcing press blanking, cuts into joint material on forcing press by bar, the two-sided trimming allowance that stays of joint material is the 2% ~ 4%mm saving material diameter;
2) shaping tack
Joint material is placed in the shaping mould with cutting edge, forcing press carries out upsetting squeeze, upsetting squeeze cylindrical and highly reach blank given size, extruding reduction of area is less than 25%, die gap placed by blank is 2% ~ 6% of blank diameter, be squeezed into modular angle degree 20 ° ~ 40 °, excess waste is extruded outside mould;
3) trimming
Blank after shaping tack is put into shaving die excision tack cylindrical excess waste, reach blank size required precision;
4) check
Size and appearance test is carried out, blank shapes and dimensional uniformity is good, steady quality is reliable by artwork.
The present invention efficiently solves low, the base precision uniformity poor of production efficiency that mechanic's essence blank-making technology exists, breaching traditional revolving body extruding metal finished blank can only lean on machine-tooled method just can reach the limitation of its precision, the scope of application is wider, and whole production process is without any machined sequence, manufacturing procedure is few, machining accuracy uniformity is good, stock utilization is high, is applicable to metal extrusion in enormous quantities and refines base processing.

Detailed description of the invention
Embodiment
The revolving body metal extrusion that the present embodiment is mainly used in the existing three kinds of first-born products of fuse of company refines base Sheet Metal Forming Technology method, and its concrete steps are as follows:
1 blanking
With
the blanking of steel wire forcing press, cuts into the joint material of length 12.6mm ~ 13mm on forcing press by the steel wire of alignment;
2 shaping tack
Put into shaping tack mould by after micro-for joint material painting extruding oil, J23-16 gap-framepress carries out upsetting squeeze, and excess waste is extruded outside mould, and the workpiece end diameter after shaping tack is
length 6.5mm, outside diameter is
length 6.5mm, overall length 13 ± 0.055mm; Extruding reduction of area is 17.19%, and the bilateral gap of blank and die is 0.2mm, and be squeezed into modular angle degree 30 °, excess waste is extruded outside mould;
3 trimmings
Put into shaving die upside down by little for the blank after shaping tack, J23-16 gap-framepress carries out trimming, the large end of blank after excision shaping tack
excess waste beyond circumference;
4 inspections
Size and appearance test is carried out by artwork.
The present embodiment is mainly used in the existing three kinds of first-born products of fuse of company, adopt the present embodiment method to produce and can reduce cylindrical grinding (3h/ thousand), outer circular test, the folder that frames up (0.5h/ thousand), face grinding (1.9h/ thousand), vibrator deburring (3.9h/ thousand), height detection, totally 6 procedures, increase trimming 1 road stamping procedure (2h/ thousand), save 5 procedures, (reducing production process 4 road, inspection process 2 road).Base production efficiency improves 4.65 times (9.3 ÷ 2 × 100%), saves processing charges (with reference to fuse head 500,000 output in 2015 estimation): save processing charges=annual production × thousand hour norm × saving man-hour=500,000 × 37.4 yuan/thousand h × (3h/ thousand × 0.5h/ thousand × 1.9h/ thousand × 3.9h/ Qian Jian ?2h/ thousand)=500,000 × 37.4 yuan/thousand h × (9.3h/ Qian Jian ?2h/ thousand)=136510 yuan.
The production efficiency of the present embodiment is 30 times of unit processing: machined 0.5/min; Punching press 15/min; That after clamping, batch machine adds 5 times: the machined 3/min of production; Punching press 15/min: and cost is low, due to the few efficiency impact extrusion pressure processing cost of operation only 0.1 yuan/part, and machined needs 0.5 yuan/part ~ 3 yuan/part; The raw material of 1/3 can be saved than machined.
