Abstract
The invention relates to a magnetic cushion block used in lamination of transformer cores, belonging to the field of transformer production technology. The invention adopts the technical scheme that a permanent magnet(2) is embedded in a phenolic aldehyde cushion block(1) and the insertion joint of the permanent magnet is wrapped by a galvanized steel sheet; the cross section of the permanent magnet is trapezoidal; first, a square groove matching with the trapezoidal permanent magnet is processed at the lower end of the phenolic aldehyde cushion block; then the permanent magnet is embedded into the square groove of the cushion block, the insertion joint is covered by the galvanized steel sheet with the thickness of 1mm; and finally, the permanent magnet and the galvanized steel sheet are fixed on the phenolic aldehyde cushion block through 401 resin adhesive. In the process of laminating the transformer cores, the magnetic side of the magnetic cushion block contacts with a transformer core roll-over table to be adsorbed on a cross grider of the transformer core roll-over table. The magnetic cushion block has the positive effects that the transformer cores can not be squashed and the cushion block can not break when the cushion block falls off in the process of lifting the transformer cores; and the magnetic cushion block is convenient to use, reduces waste and reduces the hidden safety hazards in production.
Description
Technical field
The present invention relates to a kind of magnetic force cushion block for transformer core stack, in core lamination process for the cushion block of supporting iron core stem stem, and to be adsorbed on roll-over table unshakable in one's determination, to belong to technical field of transformer production.
Background technology
In the core lamination process of transformer, the adjustment cushion block of support iron stem stem uses strap or adhesive tape to fix.After clamper for iron core standing, cushion block is easy to drop, and there is great potential safety hazard.Cushion block is random to drop, and may injure operator by a crashing object, also very easily injure iron core by a crashing object; In addition, the cushion block dropped can not recycle and cause great waste after damaging.
Summary of the invention
The object of this invention is to provide a kind of magnetic force cushion block for transformer core stack, safe, convenient, with low cost, do not drop, reusable, for supporting iron core stem stem during transformer stack, solve the problems referred to above that background technology exists.
Technical scheme of the present invention is: a kind of magnetic force cushion block for transformer core stack, inlays strong magnet forever in phenolic aldehyde cushion block, and wrap up strong magnet forever with galvanized steel plain sheet inlay place; The cross section of strong magnet is trapezoidal forever, first process a square groove matched with trapezoidal strong magnet forever in phenolic aldehyde cushion block lower end, by in the square groove of the cushion block of strong magnet embedding forever, that wraps up strong magnet forever with the galvanized steel plain sheet that 1mm is thick inlays place, and with 401 resin glues will strong magnet and galvanized steel plain sheet be fixed on phenolic aldehyde cushion block forever; There are by magnetic force cushion block the one side of magnetic force and roll-over table unshakable in one's determination to contact, for being adsorbed on roll-over table crossbeam unshakable in one's determination when core lamination.
Good effect of the present invention: clamper for iron core standing process do not exist cause because cushion block drops smash iron core, break the problems such as cushion block; Easy to use, decrease unnecessary waste, decrease in production and obtain potential safety hazard.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention front view;
Fig. 2 is the end view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
In figure: phenolic aldehyde cushion block 1, forever strong magnet 2.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the present invention will be further described.
For a magnetic force cushion block for transformer core stack, in phenolic aldehyde cushion block 1, inlay strong magnet 2 forever, and wrap up strong magnet forever with galvanized steel plain sheet inlay place; The cross section of strong magnet is trapezoidal forever, first process a square groove matched with trapezoidal strong magnet forever in phenolic aldehyde cushion block lower end, by in the square groove of the cushion block of strong magnet embedding forever, that wraps up strong magnet forever with the galvanized steel plain sheet that 1mm is thick inlays place, and with 401 resin glues will strong magnet and galvanized steel plain sheet be fixed on phenolic aldehyde cushion block forever; There are by magnetic force cushion block the one side of magnetic force and roll-over table unshakable in one's determination to contact, for being adsorbed on roll-over table crossbeam unshakable in one's determination when core lamination.
Claims (1)
1. for a magnetic force cushion block for transformer core stack, it is characterized in that: in phenolic aldehyde cushion block (1), inlay strong magnet (2) forever, and wrap up strong magnet forever with galvanized steel plain sheet inlay place; The cross section of strong magnet is trapezoidal forever, first process a square groove matched with trapezoidal strong magnet forever in phenolic aldehyde cushion block lower end, by in the square groove of the phenolic aldehyde of strong magnet embedding forever cushion block, that wraps up strong magnet forever with the galvanized steel plain sheet that 1mm is thick inlays place, and with 401 resin glues will strong magnet and galvanized steel plain sheet be fixed on phenolic aldehyde cushion block forever; There are by magnetic force cushion block the one side of magnetic force and roll-over table unshakable in one's determination to contact, for being adsorbed on roll-over table crossbeam unshakable in one's determination when core lamination.
