Abstract
The invention discloses a method for laminating main transformer cores of a locomotive, which adopts technology of a positioning hole and a positioning pin, and performs two processes of laminating core column silicon-steel sheets and plugging iron yoke silicon-steel sheets independently without interference. Cores are stood in U shape; and after coils are sleeved, upper iron yoke silicon-steel sheets are directly inserted into the cores. The method improves the flatness and seaming quality of a silicon-steel sheet laminated surface, can form flow operation, saves once laminating and once detaching processes of the upper iron yoke silicon-steel sheets, and saves the working hours.
Description
Technical field
The invention belongs to electric locomotive manufacturing technology field, relate in particular to a kind of method for laminating main transformer core of locomotive.
Background technology
The AC transmission electric power locomotive main transformer is a single-phase transformer, and the iron core of transformer is normally formed by the silicon steel sheet stack of 0.3～0.5mm.Core configuration is " mouth " font, is become with 2 iron yoke pieces by 2 iron core column, and iron core column and iron yoke are folded the thick 150～300mm that is generally.
Prior art the iron core method for laminating be the silicon steel sheet that on the iron core overturn platform, stacks iron core column and iron yoke simultaneously, after putting " " shape by drawing with one deck silicon steel sheet, adjust the seam between iron core column and iron yoke silicon steel sheet, reduce the stack gap as far as possible, to reduce the core loss that seam produces, descend the silicon steel sheet of one deck to put after adjusting again, so the silicon steel sheet with the one-level one-level successively stacks, and last stack becomes complete iron core.After stack is finished, install and fix the iron core folder, and utilized the iron core tipping arrangement that the iron core of finishing is vertically placed, carried out the colligation of iron core column again.After colligation is finished, remove iron core upper clamping piece and upper yoke silicon steel sheet, in order to mounting coil and device body insulation assembling.Can make disposable finishing of complete iron core though do like this, but there is following problem: 1, the iron core of finishing according to the prior art method, before carrying out mounting coil, must remove the upper clamping piece and the upper yoke silicon steel sheet of iron core earlier, again the upper yoke silicon steel sheet is successively turned back to iron core after mounting coil is good, such technological process causes the waste in man-hour; 2, need 4 people to work at least and can finish the stack of 1 transformer core, complex operation, inefficiency on the 1st; 3, need frequently stack face to silicon steel sheet to carry out the evenness finishing in the stack process and the abutment joint place constantly adjusts, so producers' skilled operation degree difference is bigger to the performance impact of iron core, is difficult for guaranteeing the stable or the like of properties of product.
Summary of the invention
Purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, provides a kind of and increase work efficiency, improve the method for laminating main transformer core of locomotive of technological process, stabilized product quality.
The objective of the invention is existing like this: a kind of method for laminating main transformer core of locomotive is characterized in that taking following steps:
1) on silicon steel sheet, offers location hole, correspondingly on iron core column stack platform and iron core overturn platform, add the closed assembly alignment pin;
2) location hole is corresponding with alignment pin, stack iron core column silicon steel sheet;
3) with polyester belt iron yoke silicon steel sheet is tightened in advance;
4) on the iron core overturn platform, two iron core column of folding are fixed;
5) slit according to iron core column is inserted into iron yoke silicon steel sheet between two iron core column successively, and fastening good lower clamping piece is installed, and makes it into as a whole;
6) " ㄩ " shape iron core that stands up;
7) suit coil;
8) the upper yoke silicon steel sheet is inserted iron core;
9) fastening upper clamping piece is installed.
After adopting the solution of the present invention, the employing of location hole and alignment pin has improved the evenness and the seam quality of silicon steel sheet stack face; Stack iron core column silicon steel sheet and this two procedures of plug-in mounting iron yoke silicon steel sheet all only need a people to finish, and two procedures all can independently carry out, and do not disturb mutually, can form continuous productive process; Save a lamination and a demolishing process of upper yoke silicon steel sheet, saved man-hour.
Description of drawings
Accompanying drawing 1 is the schematic diagram of the embodiment of the invention.
Embodiment
In order to guarantee the stable of iron core performance quality, by offering location hole (5) at silicon steel sheet and adding the closed assembly alignment pin at iron core column stack platform and iron core overturn platform, improve the evenness and the seam quality of silicon steel sheet stack face, get rid of of the influence of artificial quality as much as possible, improved the stability of product quality greatly properties of product.For realizing the continuous productive process of iron core stack, the stack mode that breaks traditions adopts earlier stack iron core column (3) silicon steel sheet separately, inserts the method for iron yoke silicon steel sheet (2) after finishing again.Because two iron core column are duplicate, so only 1 people of need just can stack on a little platform, with polyester belt (6) it is tightened in advance after finishing and changes next procedure again over to.Next on the iron core overturn platform, two iron core column of folding (3) are required to fix according to drawing, slit according to iron core column (3) is inserted into iron yoke silicon steel sheet (2) between two iron core column (3) successively, and fastening good lower clamping piece (7) is installed, make it into as a wholely, this procedure equally also only needs a people to finish.Two procedures all can independently be carried out, and does not disturb mutually, forms continuous productive process.
The waste in man-hour that causes for avoiding the upper yoke poststack to tear open again, iron core rises immediately and no longer builds up " " shape, but change " ㄩ " shape into, after promptly having inserted the lower yoke silicon steel sheet, and install lower clamping piece and just carry out iron core and stand up, so just can directly carry out the suit of coil (4), after finishing, the suit of coil (4) the upper yoke silicon steel sheet can be inserted iron core, save a lamination and a demolishing process of upper yoke silicon steel sheet, saved man-hour.At last, fastening upper clamping piece is installed.
Claims (1)
1. method for laminating main transformer core of locomotive is characterized in that taking following steps:
1) on silicon steel sheet, offers location hole, correspondingly on iron core column stack platform and iron core overturn platform, add the closed assembly alignment pin;
2) location hole is corresponding with alignment pin, stack iron core column silicon steel sheet;
3) with polyester belt iron yoke silicon steel sheet is tightened in advance;
4) on the iron core overturn platform, two iron core column of folding are fixed;
5) slit according to iron core column is inserted into iron yoke silicon steel sheet between two iron core column successively, and fastening good lower clamping piece is installed, and makes it into as a whole;
