Description

Improved non-bacterial meningitis necking system

Technical field

The utility model belongs to workpiece shaping process equipment, particularly relates to improved non-bacterial meningitis necking system.

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 embedded boxing to make for some canister end sockets, but have the necking equipment of pattern currently on the market There are following technological deficiency：First, plurality of specifications workpiece (needing to make the mould of dimension according to workpiece size) cannot 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 one ruler of work sheet 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, gear reducer, complicated, occupied space 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 moves 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, and shift servo motor drives driven pinch roller Longitudinally, laterally moved with active pinch roller, to complete the all-round necking processing of workpiece.It is above-mentioned existing in the prior art mainly to ask 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, easily make during necking at fillet blank produce linear deformation, influence the product quality after necking machine-shaping, And then influence the sealing effect 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, gear reducer, complicated, occupied space 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 solution 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.The prior art is basis there are problem one Part specifications need to do specific sliding block, process different size and abnormal workpieces cost is higher；Second, workpiece is placed in wedge-shaped mandrel On, by the top-pressure part workpiece pressing on top, while workpiece is moved down with wedge-shaped mandrel, and wedge-shaped mandrel struts three sliding blocks, Three shoe contact side surface of workpiece inner walls, pair of rollers workpiece carry out all-round rolling.Workpiece move down it is no spacing, with batch work Part limiting stand position is inconsistent, causes the depth of parallelism of workpiece choke to be not easy to ensure.

A kind of production of embedded air reservoir seal head is disclosed in the application for a patent for invention of Application No. 201710182589.5 Device.The invention is similarly the necking work for solving dome-shaped end socket class part, which is an assembly line, including punching press, End socket chamfered edge, end socket necking etc..The technical solution 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 cylinder steps up the column head of equipment and the dome outer wall phase of end socket at this time Cut, rolling element is tangent with head skirt, and necking rolling element rotates together with end socket, realizes all-round necking.The technical solution is deposited Technological deficiency one to be use cylinder clamping workpiece, equipment complexity, cost are higher；Second, side surface of workpiece inner wall 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 babinet 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 babinet, and the technique is in the presence of there are 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) it 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 in the contracting of different dimensions workpiece Jaws equipment.Existing necking equipment can not meet its production requirement.
