Description
Technical field
The invention belongs to Workpiece shaping process equipment, particularly relates to improved non-bacterial meningitis necking system and its in workpiece necking
Application in processing.
Background technology
Necking down process is a kind of by the square of advance stretch forming, circular blank and pipe fitting, by necking die by its mouth
A kind of forming technology that portion reduces.The scope of necking down process institute converted products than wide, mainly include canister end socket,
Cartridge case, gun shell, steel gas bottle, vertical pipe of bicycle frame, saddle saddle pipe, steel pipe drawing etc..
Require that embedded boxing makes for some canister end sockets, but have the necking equipment of pattern in the market
In the presence of following technological deficiency：First, plurality of specifications workpiece (needing to make the mould of dimension according to workpiece size) can not be processed；
Second, necking is second-rate and yield rate is low；Third, processing efficiency is low.
Existing market mainly has the necking equipment of classification：
First, the primary structure for having pattern necking equipment includes：Hydraulic cylinder Ding Lun mechanisms, hydraulic cylinder clamp system, finishing die
Tool, actuating unit.Its operation principle is that the workpiece of stretch forming is placed in above shaping dies, and hydraulic cylinder clamp system stretches out folder
Tight blank, hydraulic cylinder Ding Lun mechanisms ejection extruding workpiece makes its deformation, then provides torque driven mold by actuating unit and rotate, and comes
Complete the all-round necking processing of workpiece.The above-mentioned problems of the prior art is shown first, one set of die can only the chi of work sheet one
The workpiece of very little specification (appearance and size), processing cost remains high caused by mould cost is high；Second, clamp system uses liquid
Cylinder pressure, cost is higher, complicated；Third, power set are using motor, reductor, complicated, space-consuming is big, rotating speed not
It is adjustable.
2nd, the primary structure of non-bacterial meningitis necking equipment includes：It is workbench, hydraulic cylinder clamping device, active pinch roller, driven
Pinch roller, horizontal and vertical track, compress hydraulic cylinder, rotate servomotor, shift servo motor and programmable control system.Its work
It is that workpiece is placed in workbench as principle, and allows it between active pinch roller and driven pinch roller, hydraulic cylinder clamping device folder
Clamping of workpieces simultaneously limits it and moved up and down, and compressing hydraulic cylinder ejection workpiece pressing makes its deformation, then by operating personnel according to outside workpiece
The corresponding program of shape size establishment, control rotate servomotor and drive workbench to rotate, the driven pinch roller of shift servo motor driven
Longitudinally, laterally moved with active pinch roller, to complete the all-round necking processing of workpiece.Mainly asked existing for above-mentioned prior art
Topic one is to rotate control servomotor and mobile control servomotor to need programme-control, and fitness is poor, and workpiece rotates coherent
Property it is relatively low, blank is produced linear deformation during necking, influence the product quality after necking machine-shaping,
And then influence the sealing effectiveness of canister.Second, power set and linear moving apparatus are by Serve Motor Control, execution
Corresponding blank size is needed to program, inconvenient for operation, processing efficiency is relatively low；Third, workpiece easily produces on workbench
Transverse direction and longitudinal direction displacement；Fourth, clamp system uses hydraulic cylinder, cost is higher, complicated.
Necking equipment is mostly to have pattern equipment for dome-shaped end socket workpiece necking processing on existing market.Power source is held
Units are motor, reductor, complicated, space-consuming is big, rotating speed is non-adjustable, high equipment cost.
The Patents documents that applicant retrieves are as follows：
A kind of reducing device is disclosed in the application for a patent for invention of Application No. 201410685758.3, mainly solves circular arch
The necking processing of shape end socket class part, its technical scheme are to have pattern equipment, including main shaft, slide, multiple slides, annular elastomeric
Spring, wedge-shaped mandrel, the top-pressure part for workpiece pressing and the roller of necking work.It is basis that the prior art, which has problem one,

End socket chamfered edge, end socket necking etc..The technical scheme of wherein end socket necking is：End socket is positioned on positioning disc, cylinder steps up
Equipment promotion piston rod steps up the end socket of shrinkage waiting open, and now cylinder steps up the column head of equipment and the dome outer wall phase of end socket
Cut, rolling element is tangent with head skirt, and necking rolling element rotates together with end socket, realizes all-round necking.The technical scheme is deposited
Technological deficiency one to be use cylinder clamping workpiece, equipment complexity, cost are higher；Second, side surface of workpiece inwall and setting circle
Disk does not contact, and workpiece is yielding in rolling process；Third, being needed to do the positioning disc of correspondingly-sized according to specification of workpieces, processing is made
Valency is high.
With regard to applicant understand scope for, in existing national standard or industry specifications for necking process equipment, plus
Product performance index after work technique and machine-shaping does not carry out specification or constraint, because using the workpiece master after necking down process processing
It is used to make casing class product, its final products is mainly realized by welding procedure, for necking class workpiece in welding
The depth of parallelism of platform and its bottom surface has higher requirements and otherwise should will make product hermeticity and U.S. without obvious deformation after part necking
Sight degree is affected, and for these reasons, ensures workpiece choke bit parallel degree after processing and it is deformed without obvious, in satisfaction
The necking processing request for stating workpiece is not only the design difficulty of necking process equipment, and is also the main research and development side of the kind equipment
One of to.
With city infrastructure and real estate industry develop rapidly and the increasingly increase of mining demand, be
Dumper provides unprecedented development space, and the market demand of dumper matching component hydraulic oil container also gradually increases.
Conventional hydraulic fuel tank end socket uses embedded seam weld technique with casing, and the technique has problems with：When currently without
Reliable lossless detection method, welding quality can only lean on technique sample and destructive testing inspection；Second, at its lap joint
Tensile strength and fatigue strength are relatively low；Third, seam-welding equipment power is big, equipment investment is big, maintenance difficult, and high-power welding machine is to electricity
Net produces larger load.Using embedded boxing (CO2Gas shielded arc welding) can then solve the deficiency of above welding procedure.As used
Embedded boxing, then need it is a kind of can manufacture, high yield rate, necking quality is good, is applicable the contracting of different dimensions workpiece
Jaws equipment.Existing necking equipment can not meet its production requirement.
