Description
Technical field
Leading for pad is stretched the present invention relates to a kind of technical field of automobile die guider, more particularly to suitable for press
To device.
Background technology
At present, generally in automobile stamping forming process, to ensure the surface quality of vehicle exterior cladding element and improving sheet material
Tensile property, stamping machine is typically equipped with die cushion device, the stamping parts being molded for ejection die intracavitary；And it is more first
The press entered, sheet material is all to utilize stretching pad reverse-drawing shaping.Therefore must have very high for the stationarity that ejection is padded in stretching
It is required that.
Stretching pad is commonly called as lower air cushion, on forcing press, when plate is stretched, and stretching pad is used to clamping and fixing stretching
Part, to avoid tensioning member fringe margin.Meanwhile, stretching pad is used as material beating device in sliding block backhaul, and tensioning member is sent into transmission plane.Have
When, stretching pad may be used as material beating device use.Modern stretching pad typically all uses hydraulic pressure or pneumatic actuation.
There are following several ways in stretching mat structure arrangement generally in press base：
A) stretching one supporting plate of rim strip
B) multiple stretching one supporting plate of rim strip
C) multiple stretchings are padded and respectively come with a supporting plate
First two structure arrangement claims single crown configurations, and the third claims many crown configurations.The stretching pad of many crown configurations
It can act respectively, pressure-pad-force can also be adjusted respectively, thus the need for complicated drawing process can be met.
Stretching pad provisioned in CPA-3-100 (the former line of punching press 11) automated production bar line uses a stretching rim strip
Single apical cap form of one pallet, air pressure control.The ejection height of stretching pad is the motor driving worm and gear by bottom to adjust
Section, when mould is determined, stretching pad ejection height should be adjusted to fixed value, in process of production stretching pad apical cap rising be by
Baric systerm realizes, compressed air enters cylinder piston bottom, driving piston rise after by intermediate connector by apical cap
Jack-up, and after apical cap jack-up then can direct jack-up mobile work platform bottom top rod, so as to realize that stretching pad rises function, decline
When piston base do not supply, whole stretching pad drops down onto bottom by deadweight.
Intermediate connector knockdown is found in use to cause drawing cushion function to fail.On intermediate connector
The connecting bolt of the bulb cover plate in portion and stretching pad apical cap is broken, and bulb cover plate drops in cylinder head, and guide sleeve is tilted, its with
Bottom connecting bolt fracture.
The reason for causing problem above has at 2 points：One is former design problem, but the defect in the design of modification mechanism will consume
When effort, have a strong impact on front and produce, therefore do not consider；Two be design in terms of mould due to mould in itself make it or it is many or
There is unbalance loading less, so this respect reason is actual not to have operability.
The content of the invention
The brief overview of one or more aspects given below is to provide to the basic comprehension in terms of these.This general introduction is not
The extensive overview of all aspects contemplated, and it is also non-to be both not intended to identify the key or decisive key element of all aspects
Attempt to define the scope in terms of any or all.Its unique purpose is to provide the one of one or more aspects in simplified form
A little concepts think the sequence of more detailed description given later.
It is an object of the invention to solve the above problems there is provided the guider of press stretching pad, stretching pad is optimized
In guide frame, recovered drawing cushion function, improved the safety coefficient of connector, saved maintenance man-hours and maintenance cost.
The technical scheme is that：A kind of guider, it is characterised in that the guider include top bulb,
Intermediate connector, bottom bulb and bottom linker；Apical cap is connected with top bulb, and top bulb passes through intermediate connector and bottom
Portion's bulb connection, bottom bulb is connected by bottom linker with straight spur unit；Is opened up in the side of intermediate connector
One oilhole, the top surface of intermediate connector and bottom surface are all the arcwall face of outwardly convex, are opened along the length direction of intermediate connector
If penetrating into the second oilhole of bottom surface from top surface, the first oilhole and the second oilhole insertion；First sphere of top bulb and centre
The top surface matching of connector, the second sphere of bottom bulb is matched with the bottom surface of intermediate connector.
In one embodiment, first group of radiation from the centre of sphere to external radiation is opened up on the first sphere of the top bulb
Oil groove and first group of annulus oil groove, first group of radiation oil groove, first group of annulus oil groove and second oilhole are all mutually communicated.
In one embodiment, shoulder hole is provided with the center of the relative another side of the sphere of top bulb first,
The top bulb is connected by the screw element being located in shoulder hole with the apical cap.
In one embodiment, the second sphere of the bottom bulb also includes second group of radiation from the centre of sphere to external radiation
Oil groove and second group of annulus oil groove, the second spoke group are penetrated oil groove, second group of annulus oil groove and second oilhole and are all mutually communicated.
In one embodiment, the bottom linker is ladder shaft-like, and cylindrical in the bottom linker is provided with axle
Hole and/or pin-and-hole and/or fabrication hole, the axis hole and/or pin-and-hole of the straight spur unit output end and the bottom linker
Cylindrical axis hole and/or pin-and-hole position correspondence.
In one embodiment, the guider is the guider that press stretches pad.
In one embodiment, the bottom for stretching pad in the press is additionally provided with buffer unit.
Present invention contrast prior art has following beneficial effect：
1) the intermediate connector top surface in guider and the design of the arcwall face of bottom surface and and forward and backward bulb part are passed through
Mating spherical surfaces, be oriented to it and produce certain Flexible Transmission, it is to avoid the fracture of the bolt part between preceding hat and anterior bulb.
2) oilhole that radiation oil groove, annulus oil groove and the intermediate connector set in top bulb and bottom bulb is set is passed through
It is logical, top bulb, the radiation oil groove that bottom bulb is set, annulus oil are penetrated into by oil filler again from the oilhole of intermediate connector
Groove, makes its top bulb and the sphere of bottom bulb obtain sufficient lubrication, it is to avoid during jacking connector and top bulb,
Dry friction is produced between the bulb of bottom, while improving lubricating condition, the tangential stress of unbalance loading is reduced.
3) it can be ensured by the axis hole of the cylindrical setting of piston connector, pin-and-hole and straight spur unit output shaft is had
The reliable connection of effect, while the fabrication hole in the cylindrical setting of bottom linker can ensure that bottom linker is effectively easily torn open
Remove.
4) in order to improve stress condition, the reload buffer device on the lathe bed for stretching rebasing portion bears the part of apical cap
Weight, it is possible to absorb vibrations during compressor operation.
Optimized in terms of improving lubricating condition and increasing force part, installed lubrication hole additional and be lubricated.It is such
Structure optimization causes junction shear resistance to improve 4 times, and the improvement of lubricating condition causes cross shear to be kept to original one
Half, general safety coefficient improves 8 times.High repairing entrusted to other units expense is not only saved, maintenance work in the future is also reduced
Amount, greatly reduces equipment on-line outage rate, have received good effect.
