Abstract
A large casing machining process includes bending plate into main bent part and side bent parts according to the required sizes, punching plate into punched round corner parts by die set according to the required sizes of the casing, and welding the bent parts and the punched parts to form the large casing. Because of no need of large dies and large punching equipment, the present invention has greatly reduced cost.
Description
Technical field: the present invention relates to a kind of processing method of casing, particularly relate to a kind of processing method of large scale casing.
Background technology: the hood on excavator and other engineering machinery is a vitals that is related to the complete machine moulding.In those early years, China not too payes attention to the industrial modeling of product, and hood adopts the panel beating welding to form mostly.In recent years, along with the enhancing of people's aesthetic consciousness, the hood of the orthodrome transition of employing mould production has become the inexorable trend of era development.But, adopt traditional mould production also to produce some problems.Generally speaking, the hood on the engineering machinery is a cuboid, and size is big (length is near 2000mm, about width 1000mm, highly near 300mm).The large scale product is if adopt the unitary mould processing like this, and essential two overlap stretching dies, and the size of mould is big, and not only mold materials consumption is many, and requires the hydraulic press of large-tonnage (more than 800 tons).
Technology contents: it is less that technical problem to be solved by this invention provides a kind of mould therefor size, the processing method of the machining large-sized casing that die cost is low.
The technical solution adopted in the present invention is such, because the large scale casing is the solid of a rule, its fillet partly can be separated, residue partly can be divided into several panel beating bodies: the housing of broad and side thereof partly are that main body and narrower housing side are side surface body, and they form main bent part spare and side bending part by bending; The fillet of large scale casing partly is stamped to form with mould, with itself and the corresponding welding of main bent part spare and side bending part, the large scale casing.
The steps include: sheet material is gone out main bent part spare and side bending part by large scale chassis body and side required size bending; With sheet material by the fillet of large scale casing partly required size stamp out partly stamping parts of fillet with mould, again with the partly corresponding welding of stamping parts, main bent part spare and side bending part of fillet, the large scale casing.
Owing to adopted technique scheme, the fillet of large scale casing is partly separated processing, like this, only need carry out bending to large scale chassis body and side main body, and fillet stamping parts processing partly only needs small mould, with the partly corresponding welding of stamping parts, main bent part spare and side bending part of fillet, like this, whole processing and making process, need not large mold and large-scale pressing equipment, die size greatly reduces, and die cost descends significantly than unitary mould, and the requirement of pressing equipment is greatly reduced.After the large scale casing that processes was in this way handled by polishing and paint, the product that presentation quality and unitary mould process was suitable.
Description of drawings: Fig. 1 is the Engine Casing structural representation that this processing method processes.
The specific embodiment:,, its fillet partly can be considered as the stamping parts that cuts out by rotary body because Engine Casing is the tetragonal body of a rule for Engine Casing.
Sheet material is gone out main bent part spare 1 and side bending part 6,7 by the bending of Engine Casing required size; With sheet material by the Engine Casing fillet partly required size stamp out by mould and revolve body, by mould rotary body is cut out stamping parts 2,3,4,5 by axial quarter then; With stamping parts 2,3,4,5 and bending part 1,6, the 7 corresponding weldings of side bending part, Engine Casing.
Because removing the bending part of fillet is to be formed by the sheet material bending, its size is adjustable, that is to say, the length of whole hood and width are adjustable, and this is very favourable for new product development.
This invention also applicable to the processing of miscellaneous equipment, so long as fillet is partly separated, is bent into bending part with main body and side from integral body, with bending part and fillet stamping parts welding partly, just belong to protection scope of the present invention.
Claims (3)
1, a kind of processing method of large scale casing, the fillet of regular geometric body large scale casing is partly separated, residue partly can be divided into several panel beating bodies: the housing of broad and side thereof and be side surface body partly for main body and narrower housing side, and they form main bent part spare and side bending part by bending; The fillet of large scale casing is partly come out with the small mould punching press, again with the partly corresponding welding of stamping parts, main bent part spare and side bending part of fillet, the large scale casing, it is characterized in that: above-mentioned processing method is finished like this: sheet material is gone out main bent part spare and side bending part by the bending of large scale casing required size; With sheet material by the fillet of large scale casing partly required size stamp out large scale casing fillet stamping parts partly by mould, with the partly corresponding welding of stamping parts, main bent part spare and side bending part of fillet, the large scale casing.
2, the processing method of large scale casing according to claim 1, it is characterized in that: described fillet partly stamping parts is processed with following method: sheet material is struck out rotary body by fillet part required size by mould, with mould the axial equal portions of rotary body are cut out stamping parts then.
3, the processing method of large scale casing according to claim 2 is characterized in that: with mould the axial quarter of rotary body is cut out stamping parts.
