Description
Technical field
The invention belongs to field of machining, and in particular to a kind of bending device of metal sheet.
Background technology
The features such as sheet metal component has lightweight, intensity high, low cost, good scale of mass production performance, in electronic apparatus, leads to
The fields such as letter, auto industry, medicine equipment are widely applied.Particularly in computer housing, mobile phone, MP3, the metal of tabular
It is essential part.As the application of sheet metal component is more and more extensive, the demand of sheet metal component is also increasing, processing
The requirement of precision also more and more higher.
In sheet metal component process, mainly bender mould is placed on stamping machine, is then placed into metal sheet
Metal sheet is bent in bending mold, in bending process, the active force between upper and lower mould is put on metal sheet,
Metal sheet is produced plastic deformation, different upper die and lower die are selected according to the shape of sheet metal component in processing, work as metal
When plate is more complicated, the shape of bending is also more complicated, now needs frequently to change mold and lower mould, the mistake of replacing
What journey compared wastes time and energy；And in process, work piece can the heat production after plastic deformation, now decontrol work piece,
The rebound performance of work piece is most strong, can cause the precision of the sheet metal component after machining and reduce.
The content of the invention
The invention is intended to provide a kind of metal sheet decompressor, to realize the quick replacement of lower mould, processing effect is improved
Rate.
In order to achieve the above object, base case of the invention is as follows：A kind of metal sheet decompressor, including by up to
Under the hydraulic pressure platform, frame and the board that are sequentially connected, the hydraulic pressure platform is slidably connected with the upper end of frame, the lower end of frame and board
It is fixedly connected, and hydraulic pressure platform is arranged on the surface of board, is detachably provided with mold on the lower surface of the hydraulic pressure platform, institute
The rotating shaft for being horizontally disposed with board and having and rotated with board and be connected is stated, and the lower mould of some different models is circumferentially installed in rotating shaft
Tool, lower mould is vertical with rotating shaft, and mold is set towards rotating shaft；Also include hollow gag lever post, the gag lever post is passed through
Lower mould is detachably connected with board, and gag lever post is horizontally disposed；The center of the lower mould is provided with first through hole, and spacing
The second through hole of gag lever post and first through hole is communicated with bar, also including annular seal, the seal is fixedly mounted on
First through hole lower end；One end of the gag lever post is provided with blasthole, and the other end of gag lever post is provided with apopore, at blasthole
Be provided with laser generator, be socketed with transparent glass reinforced plastic pipe in the gag lever post and first through hole, and glass reinforced plastic pipe outer wall
Inwall with gag lever post and first through hole is contacted, and the upper end of first through hole is provided with transparent glass epoxy.
The principle of base case：Before operation, start hydraulic pressure platform, moved on hydraulic pressure platform, mold on hydraulic pressure platform lower surface with
Lower mould is separated, and then dismantles the gag lever post on board, removes gag lever post；Then rotating shaft, rotating shaft is driven in rotating shaft
Lower mold rotation, now selects required lower mould, then by corresponding lower mold rotation to the underface of mold, under making
Mould is relative with mold, and gag lever post then is passed through into lower mould, and the two ends of gag lever post are connected with board, now make first through hole
Relative with the second through hole, the seal at first through hole is contacted with the second through hole, first through hole is sealed with the second through hole；Then
To water flowing at the blasthole of gag lever post, water is now also contained in first through hole, open laser generator, now the glass in gag lever post
Glass steel pipe is reflected light, is totally reflected in water with the time, and light travels to the second through hole, first from gag lever post
Glass reinforced plastic pipe in through hole proceeds reflection to light, and the light after reflection is gathered in shape on the glass epoxy of the upper end of first through hole
Into luminous point；Then work piece is placed on lower mould, makes the light in the center of the folding line of work piece and first through hole
Point is overlapped, and then starts hydraulic pressure platform, and hydraulic pressure platform is moved down, and mold overlaps with lower mould, and work piece is bent, and now flows
Water is cooled down to work piece；Then moved on hydraulic pressure platform, take out work piece, be further continued for the processing of next workpiece.
The advantage of base case：The 1st, the lower mould of some different models is circumferentially installed in rotating shaft, and rotating shaft can be with respect to machine
Platform is rotated, and lower mold rotation can be driven during rotation, selects different lower moulds relative with mold, it is to avoid to lower mould
The replacing for being capable of achieving lower mould is dismounted, the process of replacing is very simple and quick, can reduce replacing construction, improved processing effect
Rate；2nd, when gag lever post passes through lower mould, lower mould is relative with mold, so effectively lower mould can be carried out it is spacing, it is anti-
Rotating shaft is rocked when only processing, the stability of intensifier；3rd, water inlet and apopore are respectively equipped with the two ends of gag lever post, while
Gag lever post is provided with the second through hole connected with first through hole, the heat quilt that work piece and lower mould are produced in process
Water is taken away, and is easy to reduce work piece quick cooling and shaping the rebound performance of work piece, improves machining accuracy；4th, it is spacing
Transparent glass reinforced plastic pipe is equipped with bar and first through hole, effectively the light that laser generator is produced can be reflected, it is to avoid
Light decrease fast；The glass epoxy that the upper end of first through hole is set, can make light in first through hole internal reflection, and light is reflected in fiberglass
On plate, light, light-transmissive workpiece with holes are have accumulated on glass epoxy, and then conveniently work piece with holes is positioned.
Whole device realizes the conversion of lower mould by quick rotation, eliminates the process that mould is constantly dismounted, effectively
Improve the quick band of the water energy in processing efficiency, and gag lever post and go down the heat that mould and work piece are produced in process
Amount, quickly by work piece cooling and shaping, reduces the rebound performance of work piece, improves machining accuracy.
Preferred scheme one：Based on scheme preferred scheme, also including geometrical clamp, the geometrical clamp is fixedly mounted on machine
The lower end of platform, and geometrical clamp upper surface and shaft contacts.By above-mentioned setting, in rotating shaft, geometrical clamp connects with rotating shaft
Touch, allow the rotation that rotating shaft is smooth, when mold moves down pressing work piece, now can be delivered to for active force by rotating shaft stress
On geometrical clamp, and then countershaft is supported, and makes device more stable in process.
Preferred scheme two：Preferably one preferred scheme, is equipped with stopper slot on the two ends of the gag lever post, and
Board is provided with the limited block offseted with stopper slot.By above-mentioned setting, when the limited block on board is embedded into stopper slot, limit
Position bar can be just fully mounted on board, while first through hole is connected with the second through hole, need not now be rotated further by gag lever post makes the
One through hole aligns with the second through hole, simplifies operating procedure, can quickly be adjusted.
Preferred scheme three：Preferably two preferred scheme, two ends and the board of the gag lever post are snapped connection.It is logical
Above-mentioned setting is crossed, gag lever post is snapped connection with board, convenience is by the fast quick-detach of gag lever post and board and is quickly connected, can be effective
Improve processing efficiency.
