Description
Punching folding combined shaper for metal thin plate is mechanical, electric, the hydraulic pressure of collection, pneumatics
In one, collect corner cut, punching, bending, flanging function in the metal forming equipment of a machine,
What be mainly used in sheet metal once-combinedly washes off the processing that is shaped, as outer case in the household electrical appliance
The once-forming processing of " U " shape part.
Thin plate " U " shape part is the inside and outside box parts of typical household electrical appliances, generally to pass through corner cut,
Punching, the long limit of folding, folding minor face four procedures are finished.At present, both at home and abroad to thin plate " U "
The production technology equipment branch two big classes that the shape part is shaped and takes.One class is to adopt many general units
Produce, equipment is arranged by certain technological process, at goods by manually being transported to from last process
Next procedure.This mode of production is selected common apparatus for use, and go into operation soon, invest and economize, but institute
Need table of equipment number is many, the staff is many, floor space is big, because of repeatedly locating and carry, system
The low precision of part, turnover are slow, at the bottom of the productivity ratio, especially large-area thin plate spare more is difficult to turnover
Carrying and location are a kind of relatively backward modes of production.Its production process general as
Fig. 9.
Another kind of is to adopt Special Automatic production line, and each station is arranged sequentially, in system
Product are from the next station of a station automatic stream.Its advantage is that workpiece changes preface, production automatically
Rate height, precision height, personnel selection are lacked, and are fit to produce in enormous quantities; The problem that exists is disposable throwing
Money is high, production cycle is long, any fault on the production line must be shut down or stop production, take up an area of
Bigger.Its production process is general as Figure 10.
Punching folding combined shaper for metal thin plate provided by the invention, corner cut, punching, bending, the flanging function of each station on the Special Automatic line are integrated in a machine, make at goods and need not to transfer once-forming in week between each station, be used to replace many general units or Special Automatic line to produce on a fairly large scale, small investment, go into operation fast, take up an area of little, personnel selection less, the precision height, and have higher productivity ratio and certain versatility, adapt to the new demand that every profession and trade is produced typical thin plate " U " shape part.
