Abstract
The invention relates to a clamping method for an iron core and an iron yoke of a transformer and dedicated tooling, and belongs to the technical field of transformer production. The technical scheme is that the dedicated tooling comprises an upper clamping beam (1), a lower clamping beam (2) and clamping screws (3). Holes which are mutually matched are arranged at four corners of the upper clamping beam and the lower clamping beam. The four clamping screws penetrate into the holes at the four corners respectively and fastened through bolts to form a frame structure. Holes of the upper clamping beam and the lower clamping beam are long round holes and are used for adjusting the distances among the clamping screws. Threads at ends of the clamping screws are used for adjusting the space between the upper clamping beam and the lower clamping beam and suitable for iron cores of different diameters. According to the clamping method for the iron core and the iron yoke of the transformer and dedicated tooling, clamp parts of the iron core and the iron yoke are clamped through the coordination of a hydraulic jack, and accordingly, the iron core clamping force is increased, laminated sheets are prevented from moving relative to the clamping parts during the rising of the iron core, and noise and losses of the transformer are reduced during the operation of the iron core. Internal distances of the clamping parts can be well controlled, the deformation of the clamping parts is reduced, the iron core clamping force is increased, the working efficiency is improved, and the manual operation burden is reduced.
Description
Technical field
The present invention relates to a kind ofly for transformer core iron yoke clamping means and special tooling, belong to the transformer production technical field.
Background technology
In transformer production, transformer core clamping force in manufacturing process must guarantee, and is inadequate such as clamping force unshakable in one's determination, easily causes many-sided impact such as core loss, noise, particularly important in high-power transformer.Can play certain clamping effect by clamping the frocks such as clamp, clamped beam behind the clamper for iron core standing, before standing up, because manpower can not all tighten bolt and puts in place, and the reason such as part core clamping distortion, can not guarantee that clamping force unshakable in one's determination reaches right pressure.Often occur behind the clamper for iron core standing seam large, alter the quality problems such as sheet, noise exceed standard, zero load exceeds standard, have a strong impact on product quality and image, also increased stand up rear repair time and production cost unshakable in one's determination simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of for transformer core iron yoke clamping means and special tooling, save time, laborsaving, guarantee product quality simultaneously, distance in the control folder reduces the deflection of folder, increase clamping force unshakable in one's determination, solve the problems referred to above that background technology exists.
Technical scheme of the present invention is: a kind of for transformer core iron yoke clamping special tooling, comprise clamped beam, lower clamped beam and clamping screw, on four angles of upper clamped beam and lower clamped beam, the hole of mutual coupling all is set, four clamping screws penetrate respectively in the hole at four angles, pass through bolted, consist of frame type structure, the hole of upper clamped beam and lower clamped beam is slotted hole, be used for regulating the distance between clamping screw, the end thread of clamping screw, the spacing that is used for regulating upper clamped beam and lower clamped beam, the iron core of suitable different-diameter.
A kind ofly adopt above-mentioned special tooling for transformer core iron yoke clamping means, be placed on lower yoke window unshakable in one's determination place before clamper for iron core standing, the position is in center, window place; Spacing according to clamped beam and lower clamped beam on the thickness adjusting special tooling unshakable in one's determination; Hydraulic jack is arranged between core clamping and the upper clamped beam, clamps core clamping by hydraulic jack, measure distance in the core clamping in clamping process, interior distance stops to clamp after reaching requirement; Fastening iron yoke tape and feet unshakable in one's determination clamp iron yoke unshakable in one's determination fully, then with the jack pressure release, remove special tooling, and after finishing, iron core stands up.
After upper clamped beam and lower clamped beam install, wide according to lamination, calculate required clamping force, then select the hydraulic jack of coupling, thereby control iron yoke clamping force unshakable in one's determination.
Good effect of the present invention: cooperate by hydraulic jack, clamp yoke clip piece unshakable in one's determination, distance reaches norminal size in the folder thereby make, and increases clamping force unshakable in one's determination, prevents the relative folder displacement of time-out lamination unshakable in one's determination, reduces transformer noise and loss when iron core moves.Can well control distance in the folder, reduce the deflection of folder, increase clamping force unshakable in one's determination, increasing work efficiency alleviates the manual operation burden
