Abstract
The utility model discloses a novel transmission shaft spline spindle nose forges mould, including shaping die and tight die of clamp, forming die is equipped with shaping die cavity, its characterized in that: the die cavity of the forming female die is provided with an inner circular surface and a step surface in the circumferential direction, and the inner diameter of the step surface is larger than that of the inner circular surface. And a circular arc chamfer is arranged at the transition position between the inner circular surface and the step surface. The utility model discloses reduce the machining cutting allowance, improve material utilization rate, realize energy saving and consumption reduction, reduce material cost reduces and forges the degree of difficulty. The utility model discloses the forging machining allowance of processing is less, has improved the production efficiency of machining greatly, has practiced thrift machining cutter cost. And an arc chamfer is arranged at the transition position between the inner circular surface and the step surface, so that the forging piece can be smoothly demoulded even if the clamping female die does not work.
Description
Technical field
The utility model relates to the power transmission shaft forging mold, especially relates to a kind of splined driveshaft spindle nose forging mold.
Background technology
Traditional splined driveshaft spindle nose adopts flat forging form, and is as shown in Figure 1, and forging mold comprises clamping die 1, molding concave die 2, and molding concave die 2 middle parts are mold cavity 3, and the mold cavity 3 of this section is the circular cylindrical cavity of diameter phi 1.Because the diameter of this outside diameter and shaped article differs bigger, also need pass through further cut through the excircle of workpiece that forges.Therefore, the shortcoming of this spindle nose is following:
1. because the raw material diameter does not wait, if the raw material diameter is little, it is not tight then to clamp the die folder, can cause forging to be bonded on the punch, is difficult for the demoulding.
2. part to be cut is many, and machined metal cutting amount is big.
3. waste raw material.
4. part to be cut also need absorb heat in heating, and material heating energy consumption is high.
The utility model content
The purpose of the utility model is to provide a kind of novel splined driveshaft spindle nose forging mold that reduces the machined cutting output, reduces material heating energy consumption.
The technical scheme of the utility model is:
Novel splined driveshaft spindle nose forging mold; Comprise molding concave die and clamp die; Said mould is provided with the molding concave die mold cavity, it is characterized in that: said molding concave die mold cavity is provided with inner headed face and step surface in a circumferential direction, and the internal diameter of said step surface is greater than the internal diameter of inner headed face.
Transition position is provided with circular arc chamfering between inner headed face and the step surface.
The utility model reduces the machined chipping allowance, improves stock utilization, realizes saving energy and reduce the cost, and reduces material cost, reduces and forges difficulty.The forging allowance of the utility model processing is less, has improved mach production efficiency greatly, has practiced thrift the machine tool cost.Transition position is provided with circular arc chamfering between inner headed face and the step surface, even it is inoperative to clamp die, forging is the demoulding smoothly also.
Description of drawings
Fig. 1 is the structural representation of existing splined driveshaft spindle nose forging mold;
Fig. 2 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 2, the utility model comprises clamping die 1, molding concave die 2, is the mold cavity 3 of mould in the middle of the molding concave die 2, and mold cavity 3 comprises the step surface 5 of inner headed face 4 and right-hand member, and inner headed face 4 internal diameters are Φ 2, and step surface 5 internal diameters still are Φ 1, Φ 2＜Φ 1.Excessive part between the step surface 5 of inner headed face 4 and right-hand member adopts circular arc chamfering.
Below be the utility model and the comparing result that has a certain splined driveshaft spindle nose now:
1, consumption reduction aspect: existing splined driveshaft spindle nose, the single-piece cutting stock weight is 7.85Kg, the single-piece forge weight is 7.81Kg; And the single-piece cutting stock weight 7.55Kg of the utility model, single-piece forge weight 7.54Kg, the aspect is seen from saving material; The single-piece cutting stock weight has reduced 0.3Kg; Practice thrift 1.96 yuans for every, this product is by 120,000 of annual consumptions, and raw material can be practiced thrift 23.52 ten thousand yuan/year.
2, energy-conservation aspect: calculate from the energy consumption of heating blank; What adopt is Frequency Induction Heating; The about 0.5Kw.h of per kilogram blank heating energy consumption (0.5 degree), every with regard to saves energy 0.15 degree, and can practice thrift the electricity charge every year: * 12 ten thousand=1.17 ten thousand yuan of * 0.65 yuan/degree of 0.15 degree.The electricity charge are practiced thrift 1.17 ten thousand yuan/year;
Can know from above two aspects, just reduce cost 2.06 yuan at 1 forging of every production aspect saving energy and reduce the cost.
3, machined chipping allowance aspect: traditional splined driveshaft spindle nose forging allowance is bigger.The forging allowance of the utility model processing is less, has improved mach production efficiency greatly, has practiced thrift the machine tool cost.
4, transition position is provided with circular arc chamfering between inner headed face and the step surface, even it is inoperative to clamp die, forging is the demoulding smoothly also.
Claims (2)
1. novel splined driveshaft spindle nose forging mold; Comprise molding concave die and clamp die; Said mould is provided with the molding concave die mold cavity, it is characterized in that: said molding concave die mold cavity is provided with inner headed face and step surface in a circumferential direction, and the internal diameter of said step surface is greater than the internal diameter of inner headed face.
2. novel splined driveshaft spindle nose forging mold according to claim 1, it is characterized in that: transition position is provided with circular arc chamfering between inner headed face and the step surface.
