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 the transformer core stack, be used for the cushion block that the core lamination process is used for the supporting iron core stem stem, and be adsorbed on the roll-over table unshakable in one's determination, belong to the transformer production technical field.
Background technology
In the core lamination process of transformer, the adjusting cushion block of support iron stem stem uses strap or adhesive tape to fix.Behind the clamper for iron core standing, cushion block is easy to drop, and has great potential safety hazard.Cushion block is random to drop, and may injure the operator by a crashing object, also very easily injures iron core by a crashing object; In addition, the cushion block that drops can not recyclingly cause great waste after damaging.
Summary of the invention
The purpose of this invention is to provide a kind of magnetic force cushion block for the transformer core stack, safe, convenient, with low cost, do not drop, reusable, supporting iron core stem stem when being used for the transformer stack solves the problems referred to above that background technology exists.
Technical scheme of the present invention is: a kind of magnetic force cushion block for the transformer core stack, and in the phenolic aldehyde cushion block, inlay forever strong magnet, and wrap up the place of inlaying of strong magnet forever with galvanized steel plain sheet; The cross section of strong magnet is trapezoidal forever, first at square groove that is complementary with trapezoidal forever strong magnet of phenolic aldehyde cushion block lower end processing, in the square groove with forever strong magnet embedding cushion block, wrap up the place of inlaying of strong magnet forever with the thick galvanized steel plain sheet of 1mm, and strong magnet and galvanized steel plain sheet are fixed on the phenolic aldehyde cushion block forever with 401 resin glues; When core lamination, the magnetic force cushion block there are the one side of magnetic force and roll-over table unshakable in one's determination to contact, are used for being adsorbed on roll-over table crossbeam unshakable in one's determination.
Good effect of the present invention: do not exist because of what cushion block dropped and causes in the clamper for iron core standing process and to smash iron core, break the problems such as cushion block; Easy to use, reduced unnecessary waste, reduced getting potential safety hazard in the production.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described by embodiment.
A kind of magnetic force cushion block for the transformer core stack is inlayed forever strong magnet 2 in phenolic aldehyde cushion block 1, and wraps up the place of inlaying of strong magnet forever with galvanized steel plain sheet; The cross section of strong magnet is trapezoidal forever, first at square groove that is complementary with trapezoidal forever strong magnet of phenolic aldehyde cushion block lower end processing, in the square groove with forever strong magnet embedding cushion block, wrap up the place of inlaying of strong magnet forever with the thick galvanized steel plain sheet of 1mm, and strong magnet and galvanized steel plain sheet are fixed on the phenolic aldehyde cushion block forever with 401 resin glues; When core lamination, the magnetic force cushion block there are the one side of magnetic force and roll-over table unshakable in one's determination to contact, are used for being adsorbed on roll-over table crossbeam unshakable in one's determination.
Claims (1)
1. magnetic force cushion block that is used for the transformer core stack is characterized in that: inlay forever strong magnet (2) in phenolic aldehyde cushion block (1), and wrap up the place of inlaying of strong magnet forever with galvanized steel plain sheet; The cross section of strong magnet is trapezoidal forever, first at square groove that is complementary with trapezoidal forever strong magnet of phenolic aldehyde cushion block lower end processing, in the square groove with forever strong magnet embedding cushion block, wrap up the place of inlaying of strong magnet forever with the thick galvanized steel plain sheet of 1mm, and strong magnet and galvanized steel plain sheet are fixed on the phenolic aldehyde cushion block forever with 401 resin glues; When core lamination, the magnetic force cushion block there are the one side of magnetic force and roll-over table unshakable in one's determination to contact, are used for being adsorbed on roll-over table crossbeam unshakable in one's determination.
