Description
?
Technical field
The present invention relates to a kind of processing method, relate in particular to a kind of current transformer aluminium shell one-shot forming processing method and process equipment thereof.
Background technology
Current transformer be a kind of utilize electrified wire around the action principle of the magnetic field effect that produces of space obtain the electric equipment of corresponding proportion electric current.Develop rapidly along with science and technology; Current transformer has been penetrated in the daily life; Adopt amorphous, nanometer crystal alloy soft magnetic materials to process mostly, carry out embedding with the aluminium shell then, and be fixedly mounted on the components and parts frame of the on-the-spot switch cubicle of wiring through the locating hole of shell.Existing aluminium shell moulding process is to adopt Mould Machining, carries out blanking earlier and repeatedly stretches and form, and its processing needs multiple kinds of molds, like the cover half of aluminium shell and the cylindrical of aluminium shell, the punch die of interior circle, machine-shaping step by step, more than the operation and efficient low; And the electric power Current Transformer is wide in variety; Each kind has various specifications, and required quantity is few again, so just need different shape, all size mould come to process accordingly; The expense that its mould drops into is bigger, causes product not have the market competitiveness.In addition, the operation of this processing method is many, and the process-cycle is long, and cost is high, the product disqualification rate is high.
Summary of the invention
The object of the invention will solve above-mentioned deficiency exactly, provide a kind of efficient high, drop into low, and can be with the one-time formed processing method of current transformer aluminium shell; Another object of the present invention provides a kind of process equipment of realizing this method.
In order to achieve the above object, the present invention provides a kind of one-shot forming processing method of current transformer aluminium shell, may further comprise the steps:
(1) aluminum profile extrusion is become the circular aluminium sheet of design size;
(2) position of adjustment cutter and cover half;
(3) the circular aluminium sheet after (1) processing is placed on cover half die tip and fixing;
(4) start cutter with the outside of aluminium shell with the inner edge drawing and forming and cut, flatten then at the bottom of the shell, take off at last expect finished product.
In order to reach one-time formed purpose, in the said step (4), start outside drawing and forming cutter earlier, with the outside drawing and forming of aluminium shell, rotary cutter cuts into the cylindrical of aluminium shell with cutting off tool the size of design; Rotary cutter with the inner edge drawing and forming of inner edge drawing and forming cutter with the aluminium shell, cuts into the interior circle of aluminium shell with cutting off tool the size of design more then.
The product that processes can meet the requirements in order to make, appearance looks elegant, and is convenient to the current transformer of packing into, and is in the said step (4), with outside drawing and forming cutter that the base pressure of aluminium shell is flat.
Adopt this technology to come processing electric current transformer aluminium shell, only need adjust relevant device according to design size earlier, swing handle again stretches three kinds of cutters successively and cuts the finished product that promptly gets the aluminium shell.This technique processing method is easy, practice thrift cost and one-shot forming, and efficient is high.
In order to realize one-shot forming processing method of the present invention; Process equipment of the present invention comprises base, and base upper surface one end is installed with cover half; The other end is connected with movable base through guide rail; Described movable base upper surface is provided with cutter and handle, the affixed feed handwheel in the end of movable base, and described cutter and movable base flexibly connect.
Movable base of the present invention can move to all around on base, to adjust it and to decide the distance between the chess; Cutter is connected with movable base through bearing, can swing handle comes the stretching or the cutting position of rotary cutter; The distance that the affixed feed handwheel in the end of movable base comes trimming tool bit and cover half.
Can reach one-time formed purpose in order to process the aluminium shell, described cutter is made up of outside drawing and forming cutter, inner edge drawing and forming cutter and cutting off tool, and these three kinds of cutters are triangularly arranged on movable base.Rotation through handle rotates successively three kinds of cutters, outside drawing and forming, inner edge drawing and forming and the cut-out of aluminium shell, the pressure end is once accomplished, and do not need more mold exchange.
Because the current transformer aluminium shell sizes size of processing can change, the feed handwheel preferably includes horizontal cutter handwheel and the vertical cutter handwheel of sending to sent to, laterally or is vertically adjusting cutter.
The prioritization scheme of such scheme is that described cutter is connected through bearing with movable base, and described cover half comprises the holder of mould and clamping mould.
After adopting above-mentioned process equipment,, can swing handle come the stretching or the cutting position of rotary cutter, can reach continuously and process once because cutter is connected with movable base through bearing; And a kind of product only needs a mould, adds man-hour mould to be placed and decide on the chess, rotates the purpose that relevant cutter reaches the cutting of stretching, makes the one-shot forming of aluminium shell ability, and do not need numerous and diverse operation of multiple working procedure, brief time and cost.In addition; The distance that the affixed feed handwheel in the end of movable base comes trimming tool bit and cover half so just can be processed the aluminium shell of all size size, only needs the distance between adjustment cutter and the cover half to get final product; And do not need other mold exchange again, avoided the investment and the waste of die sinking tool.
Beneficial effect of the present invention has:
1, processing method of the present invention row simple to operate, easy;
2, aluminium shell processing method of the present invention has reduced mould, reduces cost of investment;
3, processing method operation of the present invention is simple, with short production cycle, and product is one-shot forming ground, has improved production efficiency greatly.
4, process equipment accuracy of the present invention is high, and the aluminium shell qualification rate that processes is high, has reduced waste, remarkable in economical benefits.
