Abstract
The invention discloses a punch bridge casing producing craft. It first dose steel plate blanking, then heats to 840-860 deg. and keeps the temperature 30 min to do heat press-bending, then it heat adjusts and presses the weld groove above 800 deg., at last it welds the two press-bending shaped units into a unit.
Description
Technical field
The present invention relates to automobile press axle housing moulding process.
Background technology
Axle housing is the important spare part of automobile axle, generally adopts cast steel casting or steel plate it by punch and weld.Steel plate it by punch and weld at present general technology is: 920 ℃ of steel plate cutting-be heated to and be incubated 30 minutes-hot pressing curved-thermal recalibration-cut bevel for welding-normalized treatment-welding (two of bent into shape weld together), change other manufacturing procedure again over to.Because every bevel for welding cuts with vapour and cuts out in this technology, also needs normalized treatment after cutting, make the process complexity, the production cycle is longer, and production efficiency is lower.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, the press axle housing and production process that a kind of process is simple, production efficiency is high is provided.
The present invention realizes by the following technical solutions:
This press axle housing and production process at first is a steel plate cutting, be heated to 840--860 ℃ and to be incubated 30 minutes and to carry out hot pressing curved then, thermal recalibration and pressure welding connect groove under temperature more than 800 ℃ again, and two with bent into shape weld together moulding along bevel for welding at last.
Bevel for welding suppresses among the present invention, and carries out simultaneously with thermal recalibration, has saved the normalized treatment operation in the former technology, has the advantages that process is simple, production efficiency is high, production cost is low, can raise the efficiency 20-30%.
Description of drawings
Fig. 1 is steel plate cutting figure of the present invention.
Fig. 2 is that hot pressing of the present invention curves the type schematic diagram.
Fig. 3 is the vertical view of Fig. 2.
Fig. 4 is that thermal recalibration of the present invention and pressure welding connect the groove schematic diagram.
Fig. 5 is along the cutaway view of B-B line among Fig. 4.
Fig. 6 is the vertical view of Fig. 4.

The specific embodiment
Embodiment:
Fig. 1, Fig. 2, Fig. 4, Fig. 7 have provided each operation schematic diagram of technology of the present invention.At first steel plate is pressed expanded view blanking shown in Figure 1, can adopt numerical control vapour to cut equipment, digital control laser cutting equipment etc. and finish.Then with under plate be heated to 840--860 ℃ and be incubated 30 minutes after to carry out hot pressing by corresponding mould on forcing press curved, reach Fig. 2 and shape shown in Figure 3.This moment, the steel temperature can reduce, and being not less than under 800 ℃ the situation, carried out thermal recalibration and pressure welding and connect groove, reached Fig. 4, Fig. 5 and shape shown in Figure 6.The bevel for welding that extrudes as shown in Figure 5, it is 20 ° groove that all there is angle both sides.At last two of bent into shape are welded together moulding by shown in Figure 7 along bevel for welding.
Claims (1)
1, a kind of press axle housing and production process is characterized in that:
This technology at first is steel plate cutting, is heated to 840-860 ℃ and to be incubated 30 minutes and to carry out hot pressing curved then, and thermal recalibration and pressure welding connect groove under temperature more than 800 ℃ again, and two with bent into shape weld together moulding along bevel for welding at last.
