Abstract
The invention relates to a stamping and forming method. Blank to be stamped is arranged on a concave die and under a convex die of a die, and the convex die is stamped downwards to form a product from the blank. The stamping and forming method is characterized in that a plastic film is pasted at one side of the blank to be stamped opposite to the concave die. The stamping and forming method disclosed by the invention has the advantages that: 1. clean stamping and forming without pollution is realized to an end socket, a mould and an operation area; 2 the raw materials are easily obtained, and the cost is low; and 3 no effect exists on subsequent trimming and welding.
Description
(1) technical field
The present invention relates to a kind of impact forming method.
(2) background technology
In the punch process of plate; Usually before punching press, on blank or die surface, apply various lubricants; Thereby play the rubbing action between blank and mould isolation minimizing blank surface and mould and the effect of cooling die, improved the service life of mould and the surface quality of workpiece.But adopt the method that applies lubricant can cause mould bonding greasy dirt to cause serious oil pollution in the work-yard.And rammed product bonding greasy dirt, thereby particularly need the product of follow-up side cut or welding sequence to make because the bonding greasy dirt causes running into high temperature and catches fire and smolder, contaminated environment also causes potential safety hazard.
(3) summary of the invention
For addressing the above problem, the present invention provides a kind of impact forming method, realizes the purpose that clean drawing is not polluted working environment and eliminated safe hidden trouble.
For this reason, the present invention adopts following scheme to achieve the above object:
A kind of impact forming method places blank to be punched on the die of mould under the punch, and the downward punching press of punch is characterized in that so that blank forms product: said blank to be punched is towards the one side of the die layer of plastic film of having applied ointment or plaster.
Above-mentioned a kind of impact forming method is characterized in that: said plastic sheeting is to be that plastering agent is applied on the surface of blank to be punched with water.
Above-mentioned a kind of impact forming method is characterized in that: the thickness of said plastic sheeting is between 0.020mm-0.030mm.
Above-mentioned a kind of impact forming method is characterized in that: the thickness of said plastic sheeting is 0.025mm.
Above-mentioned a kind of impact forming method is characterized in that: said plastic sheeting cuts and leaves surplus according to the appearance and size of blank.
Above-mentioned a kind of impact forming method is characterized in that: said surplus is at least 30mm.
The invention has the advantages that: 1, realize clean drawing, end socket and mold and not pollution of operation field; 2, raw material obtains easily, and cost is low; 3, to follow-up side cut and not influence of welding.
(4) description of drawings
Fig. 1 is end cover blank and plastic sheeting released state sketch map;
Fig. 2 is the sketch map when end cover blank is carried out punching press.
(5) specific embodiment
End socket is an indispensable vitals in the many industry pressure vessel and equipments of petrochemical industry, food pharmaceutical.End socket is the end cap on the pressure vessel, is a main pressure-containing member of pressure vessel.The quality of end socket is directly connected to the long-term safety reliability service of pressure vessel.Small-sized end socket can be one time punching molded, and present embodiment is done further detailed explanation with the one time punching molded method of small-sized end socket to the present invention.
The first step, pad pasting, as shown in Figure 1.
1, selecting the thickness of plastic sheeting 1 is 0.025mm.
2, after end cover blank 2 is ready to, cut plastic sheeting 1 according to end cover blank 2 diameters, as surplus, plastic sheeting 1 can be cut into circular or square plastic sheeting 1 than the big 30mm～40mm of end cover blank 2 diameters.
3, the outer ring beyond about 60% diameter on 2 one faces of end cover blank, brushing running water 3, and plastic sheeting 1 sticked.
Second step, drawing, as shown in Figure 2.
The end cover blank 2 that 1, will post plastic sheeting 1 places on the mould on the forcing press, and end cover blank 2 posts the one side of plastic sheeting 1 towards die 5, and another side is towards punch 4.
2, press the routine operation method and realize punch forming, process end socket.
When 3, taking out end socket, can be collected in the trash receptacle, keep operationlocation's cleaning with being about to plastic sheeting 1 defective material.
4, the end socket that takes out can directly send the side cut operation to carry out following process.
Be necessary to be pointed out that at this above embodiment only is used for the present invention is further specified; Can not be interpreted as the restriction to protection domain of the present invention, the those of ordinary skill in this field can essence according to the present invention be made some nonessential improvement and adjustment to above embodiment.
