Abstract
The invention relates to a die forging forming method of a basin-shaped blank, belonging to the field of plastic molding. The method is characterized by comprising the following steps: preheating a female forming die to 200-300 DEG C; clamping the female die to the anvil surface of a forging hammer by utilizing an operating machine; taking out a bar material heated to the forming temperature from a heating furnace and putting the bar material in the female die; hammering the bar material to upset the bar material to be in the shape of a blank and to fill the die cavity of the female die; and aligning the center of a indenting punch head with the center of the formed blank to indent; and finally hammering the forming punch head to reversely extrude the blank to fill the die cavity of the female die; overturning for 180 degrees; and slightly striking the female die to take out the forge piece. The bar material is stainless steel, aluminum alloy or titanium alloy. The method has the characteristics of simple mould structure, convenience for manufacturing, short period, low cost and the like; and compared with free forging, the method provided by the invention has the advantages that the forming quality is good, the precision of the forge piece is high, the production efficiency is high, the forge piece is approximate to the outline of the part, the process redundancy is small, and the material utilization rate is high.
Description
Affiliated field
The method of a kind of basin shape of the present invention part blank moulding is specially a kind of basin shape part blank loose tooling forging forming method, belongs to the Plastic Forming field.
Background technology
Basin shape part mainly contains two kinds by the method for forging and molding at present: a kind of is that open die forging is shaped, it is open die forging annular forging piece base, because it only uses upper and lower anvil piece and some simple general utility tools on the forging equipment, have simple to operate, technological flexibility is big, the shaping characteristic that waits with short production cycle is applicable to little in batches forging production.Shortcoming is that allowance is big, and forging tolerance is big, and precision is low, and the production efficiency of forging is low, and labour intensity is big, and the stock utilization of part is on the low side.Another is a die-forging forming, makes the blank distortion obtain the forging method of required size forging by particular manufacturing craft (forging die) on forging equipment exactly.Because the appearance and size of basin shape part is generally bigger, adopt the tonnage of die-forging forming equipment needed thereby big, die manufacturing cycle is long, the cost height of forging die, investment is big, only is applicable in batch to produce.
Summary of the invention
At the problems referred to above, the invention provides a kind of a kind of cambic forging method between die forging and open die forging.Specifically may further comprise the steps:
(1) shaping female mold is preheating to 200 ℃～300 ℃, place on the anvil face of forging hammer with the machine of manipulation clamping former, to be heated to forming temperature (the forming temperature difference of different materials, as stainless steel material about 1150 ℃～1180 ℃, the forming temperature of titanium alloy is usually between 940 ℃～960 ℃, and aluminium alloy is about 460 ℃～480 ℃) bar from heating furnace, take out and be placed in the former, and the center of bar and the center of former are aligned, as shown in Figure 1;
(2) the hammering bar makes it jumping-up and is formed into blank shape and is full of cavity impression, as shown in Figure 2, overturns 180 ° and touches former, and shaping blank is come off from former, and shaping blank melts down heating again;
(3) shaping female mold is preheating to 200 ℃～300 ℃, place on the anvil face of forging hammer with the machine of manipulation clamping former, the shaping blank that is heated to forming temperature taken out from heating furnace be placed in the former, carry out pcketing with pcketing drift centrally aligned shaping blank center, guarantee pcketing drift center and blank center offset distance≤3mm, the pcketing degree of depth is identical with forming punch working portion length, as shown in Figure 3, overturn 180 ° and touch former, shaping blank is come off from former, shaping blank melts down heating again;
(4) shaping female mold is preheating to 200 ℃～300 ℃, place on the anvil face of forging hammer with the machine of manipulation clamping former, the shaping blank that is heated to forming temperature taken out from heating furnace be placed in the former, forming punch is just put along the pcketing position, the hammering forming punch makes blank be full of cavity impression by backward extrusion, as shown in Figure 4, overturn 180 ° and touch former, take out forging as shown in Figure 5.
Above-mentioned bar is stainless steel, aluminium alloy, titanium alloy.
The loose tooling forging shaping that the present invention adopts is a kind of cambic forging method between die forging and open die forging.It is on flat-die hammer, use general utility tool and movably simple die make metal forming, compare with die forging, it is simple to have a mould structure, easily manufactured, characteristics such as the cycle is short, and cost is low are compared with open die forging, the quality that is shaped is good, forging precision height, production efficiency height, forging are more near the part profile, allowance is little, the stock utilization height.
