Abstract
The invention describes an inclined hot stamping molding method of a motor bracket, which is used for manufacturing an automobile motor bracket with high performance, low cost and light weight, and belongs to the field of hot stamping. According to the molding method, a hot stamping process is adopted to simplify the molding of the motor bracket into one-step stamping molding from previous steps of stamping two parts and welding; the performance of a stamping piece is improved and the weight of the stamping piece is reduced; in a molding process, a measure of inclining a molding piece for a certain angle is adopted to change the flowing of materials in a stamping process, so that the problems of forming cracks and drapes when the parts are horizontally placed on a horizontal plane in a stamping and molding process can be solved; and the molding quality is greatly improved.
Description
Technical field
This invention belongs to the drop stamping technical field, relates generally to drop stamping technique and drip molding punching press azimuth design method.
Background technology
The at present aggravation of energy crisis and environmental problem makes energy-saving and environmental protection, safety become the main direction of auto manufacturing's development.Automotive light weight technology is important means and the method that realizes energy-saving and emission-reduction, and super-high strength steel hot spare has the double dominant that alleviates car body weight and improve security.Drop stamping unimach plate stamping part can obtain the above intensity of 1500MPa, and forming accuracy is high, is used for the important spare part of automotive security spare and structural member and other occasions, can improve automobile security performance, alleviate tare and fuel-economy performance.
Existing electric motor of automobile support adopts the manufacture method that welds together again behind two part punchings, and as shown in Figure 1, forming process is many, part is heavy, cost is high.
The present invention addresses the above problem being intended to.The present invention adopts hot press-formed technology, can not only improve electric machine support intensity, reduce sheet thickness, and a step finish the shaping of electric machine support, saved operation and mould; Adopt first the angle of inclination manufacturing process in the drop stamping field, the defectives such as the fold that has occurred when having solved common horizontal positioned, drawing crack.
Summary of the invention
The present invention adopts the super-high strength steel hot technology for solving the problem that existing electric machine support forming process is many, part is heavy, can not only alleviate and change component weight, simplify production process, and can greatly improve its performance.Drop stamping is so that electric machine support can one step forming, and part as shown in Figure 2.
In the hot stamping die design process, when adopting the large planar horizontal of electric machine support to place, fold, serious, the drawing crack phenomenon of attenuate will appear in heat-punch member, can not finely be shaped, as shown in Figure 3.For this reason, the present invention adopts the large plane inclination of electric machine support certain angle to place, and molding die to improve flowing of material in the punching course, makes stamping parts satisfy instructions for use as shown in Figure 4.
Description of drawings
The present motor supporting structure of Fig. 1.
Fig. 2 drop stamping electric machine support.
The shaping of part when the large planar horizontal of Fig. 3 electric machine support is placed.
Fig. 4 molding die that tilts.
The specific embodiment
Further specify content of the present invention and specific implementation method below in conjunction with accompanying drawing.
Certain electric machine support wall thickness 5mm as shown in Figure 1 is about tensile strength 500MPa; Tilting, to adopt thickness when hot press-formed be the 22MnB5 material of 2mm, as shown in Figure 2, loss of weight 69%, tensile strength reaches 1500MPa.
First blank heating to 930 ℃, put into rapidly afterwards the mould punching that carries cooling system and be shaped in the hot press-formed process.Hot press-formedly adopt large plane to tilt 5 ° with mould, as shown in Figure 4.
The hot press-formed method of the inclination of a kind of electric machine support of the present invention has outstanding advantages, has important practical value.
Claims (5)
1. the hot press-formed method of the inclination of electric machine support is characterized in that adopting drip molding inclination certain angle in drop stamping technique and the forming process.
2. hot press-formed method shown in claim 1 is characterized in that the formation of parts material adopts the phase transformation strengthening unimach.
3. drop stamping technique as claimed in claim 1, it is characterized in that part blank is heated to more than the austenitizing, put into afterwards and carry the cooling system fast die-forming, make drip molding in the one-time process process, finish stamping and two physical processes of martensite phase transformation strengthening.
4. hot press-formed method as claimed in claim 1 is characterized in that the large plane of drip molding horizontal by certain angle, this angular range: 3 ° ~ 30 °.
5. the hot press-formed mould of using as claimed in claim 1, inside carries cooling system.
