Description
Technical field
The invention belongs to field of machining more particularly to a kind of plate processing devices.
Background technology
During modelling, it is often necessary to plank are bent into inverted trapezoidal to meet making needs.Traditional plank
Bending mode is that directly plank is bent using trigger squeeze, however for the harder plank of material, in bending process due to
It is too big by the pressure of trigger squeeze, plank easily by dabbing, weigh wounded, cause the plank finally bent out undesirable.To understand
Certainly this problem coats drawing oil to lubricate plank, so as to protect plank in plate surface.It oils in actual production to plank
General using manually oiling, the efficiency that oils is low, and labour is big, is not easy to the batch bending of plank.
Invention content
The purpose of the present invention is to provide a kind of plate processing device, to improve plank bending quality.
In order to achieve the above object, base case of the invention is：Plate processing device, including rack, bending part, cleaning
Portion and the portion that oils, wherein：
Bending part, including the mold, fixed case and telescoping cylinder set gradually from top to bottom, the mold is equipped with groove,
Two limiting plates for fixed plate are additionally provided on mold, the fixed case is fixed in rack, the both sides up and down of fixed case
It is open, the briquetting with the groove match is fixed in fixed case, the both sides of the fixed case are also opposite to be equipped with for plank
By intercommunicating pore, the telescoping cylinder is also secured in rack, steady brace between telescoping cylinder and the mold；
Oil portion, and including fuel reserve tank and oil pump, the support base for being used to support the mold is equipped in the fuel reserve tank, described
Oil inlet pipe is communicated between oil pump and fuel reserve tank, flowline is equipped between the oil pump and the limiting plate；
Cleaning part, the pushing mechanism including being arranged on the toilet seat of the fixed case both sides and for pushing plank are described
Toilet seat is equipped with the cleaning chamber for accommodating plank, and the cleaning chamber level runs through and, the cleaning identical with groove shapes
Chamber is equipped with oil-scrapping sheet, and the pushing mechanism includes cylinder and push rod, and one end and the cylinder of the push rod are fixed, the other end and institute
It is opposite to state intercommunicating pore.
The principle of the present invention is：Plank to be bent is put on mold, limiting plate limits plank, starts oil
Drawing oil in fuel reserve tank is extracted on plank by pump, oil pump, and upper oil lubrication is carried out to plank.After oiling, start telescoping cylinder, pull rod
It is moved under the action of telescopic rod to briquetting direction, briquetting is then moved downward plank to groove inner bending relative to mold, made
Plank is bent into the shape with groove match.After plank bending forming, start cylinder, cylinder pushes push rod, and push rod will be bent
Plank afterwards is pushed into the cleaning intracavitary of toilet seat, the plank after bending oil-scrapping sheet and plate surface during cleaning chamber movement
It is in contact, so as to which the drawing oil on plank be scraped, that completes plank goes oil processing.
The beneficial effects of the present invention are：
1st, the groove match of briquetting and mold, after plank to be processed is put on mold, pull rod is in the effect of telescoping cylinder
Lower driven mold moves upwards, and briquetting is opposite to be moved downward with mold and push plank, plank is folded into groove, due to pressure
Block can coordinate with groove, therefore plank can be bent out the shape identical with groove by briquetting completely into groove.
2nd, the setting of limiting plate avoid plank to groove bend during, plank because position shakiness be upturned due to lead
Plank is caused to bend underproof problem.
3rd, after plank bending, push rod moves under the action of cylinder to pressing plate direction, one end and fixed case due to push rod
On intercommunicating pore it is opposite, plank is pushed into the cleaning chamber of toilet seat by push rod movement, and plank is in cleaning chamber movement, oil-scrapping sheet just phase
Plank is moved round about and wipes the drawing oil adhered on plank off.After push rod can also detect the bending simultaneously
Whether plank is qualified, and push rod is qualified if it can push plank, if cannot push unqualified.
4th, after plank is put on mold, the drawing oil in fuel reserve tank can be coated in plate by oil pump by oil inlet pipe and flowline
Material surface so as to be lubricated processing to plank, prevents from being pulled in plank bending process, effectively reduces rejection rate.
Further, the one end of the push rod far from cylinder and the groove match.
The one end of push rod far from cylinder can with groove match, since the shape processed required for plank is and the groove
Shape is identical, therefore after plank bending, push rod can be completely attached to plank, consequently facilitating shifting plank onto cleaning intracavitary.
Further, the frizing end of the oil-scrapping sheet is equipped with protective case.
The setting of protective case scratches plate surface during drawing oil being scraped to avoid oil-scrapping sheet, influences beauty.
Further, the bottom of the toilet seat be equipped with the accommodating chamber that connects of cleaning chamber, the accommodating chamber with it is described
Return duct is communicated between fuel reserve tank.
Drawing oil on plank is just instilled in accommodating chamber after being scraped by oil-scrapping sheet, by return duct by the stretching in accommodating chamber
Oil is flowed back into fuel tank and is reused, and avoids causing the waste of drawing oil.
Further, the limiting plate is arc-shaped.
The limiting plate of arc avoids plank plank slip during bending that bending effect is caused to reduce or even do not conform to
Lattice.
Further, the pull rod for two and is oppositely arranged on the mold.
Two pull rods are oppositely arranged on mold, ensure that mold movement under the action of pull rod is more steady.
