Abstract

The utility model relates to an electromagnet for a bending machine. The electromagnet for the bending machine comprises field coils, a disk body, a coiling-out plate and a connecting box. A plurality of disk-body holes are arranged in the disk body, the field coil is arranged in each disk-body hole, filling materials are arranged in a clearance between each field coil and the corresponding disk-body hole, the coiling-out plate is arranged below the disk body, coiling-out holes which correspond to the disk-body holes are arranged in the coiling-out plate, and the connecting box is arranged below the coiling-out plate. The electromagnet for the bending machine has the advantages that the electromagnet for the bending machine is simple in structure and long in service life; when the electromagnet for the bending machine is used, electromagnetic stability is high, magnetic conducting property is good, and holding force is large; and the structure of the bending machine is simplified, and hoisting and bending of a large-size workpiece are facilitated.

Description

A kind of bender electromagnet

Technical field

The utility model relates to a kind of electromagnet, refers more particularly to a kind of bender electromagnet.

Background technology

The bender that uses at present adopts two ends to set up post mostly, connect the structure of pressing beam on the column, the bender complex structure of this structure, steering program is loaded down with trivial details, simultaneously, because the existence of column, limited the bending length of bender, can't carry out bending for large component (length exceeds the workpiece of bender lathe length), in addition, this bender is when work, by pressing beam to compress from treating bending workpieces top, owing to pressing the restriction of beam, can only be positioned over first on the material drag frame of platform of machine tool sidepiece when large-scale workpiece is positioned over the operating position by boom hoisting, then by manually workpiece being pushed into platform of machine tool from the material drag frame, complex operation, labour intensity is large, inefficiency; Also there is now part producer to adopt magnechuck absorption workpiece, but the workpiece that at present magnechuck used of on the market bender can only sticking 10000N, just can't reach the effect of sticking for weight greater than the workpiece of 10000N, therefore, should further improve prior art.

The utility model content

The purpose of this utility model provides a kind of bender electromagnet, to overcome the deficiency of the above-mentioned aspect of existing product.

The purpose of this utility model is to be achieved through the following technical solutions:

The described a kind of bender electromagnet of the utility model embodiment, comprise magnetizing coil, disk body, outlet board and terminal box, described disk body is provided with some disk bodies hole, disk body is provided with magnetizing coil in the hole, between magnetizing coil and the disk body hole packing material is housed, the disk body below is provided with outlet board, and outlet board is provided with the wire hole corresponding with the disk body hole, the diameter of wire hole is less than the diameter in disk body hole, and the outlet board below is provided with terminal box.

Preferably, described disk body hole arrangement mode is array.

The beneficial effects of the utility model are: the utility model is simple in structure, high life, in use, the utility model electromagnetism stability is strong, magnetic property is good, holding force is large, and the utility model has been simplified the structure of bender, is convenient to lifting, the bending of large-scale workpiece.

Description of drawings

The below is described in further detail the utility model with reference to the accompanying drawings.

Fig. 1 is the structural representation that the described a kind of bender of the utility model embodiment is used electromagnet;

Fig. 2 is the transverse sectional view that the described a kind of bender of the utility model embodiment is used electromagnet.

Among the figure:

1, outlet board; 2, terminal box; 3, disk body; 4, magnetizing coil; 5, disk body hole; 6, wire hole; 7, packing material.

The specific embodiment

Shown in Fig. 1-2, the described a kind of bender electromagnet of the utility model embodiment, comprise magnetizing coil 4, disk body 3, outlet board 1 and terminal box 2, described disk body 3 is provided with some disk bodies hole 5, disk body hole 5 arrangement modes are array, be provided with magnetizing coil 4 in the disk body hole 5, in the gap between magnetizing coil 4 and the disk body hole 5 packing material 7 is housed, disk body 3 belows are provided with outlet board 1, outlet board 1 is provided with the wire hole 6 corresponding with disk body hole 5, the diameter of wire hole 6 is less than the diameter in disk body hole 5, and outlet board 1 below is provided with terminal box 2.

During concrete production, magnetizing coil 4 is placed in the disk body hole 5, be placed with packing material 7 in the gap in magnetizing coil 4 and disk body hole 5, outlet board 1 is fixed in the disk body 3, the wire of magnetizing coil 4 is passed wire hole 6, and be connected on the terminal box 2, during concrete the use, the terminal box 2 of electromagnet and the power supply of bender are linked together, during work electromagnet is switched on, make electromagnet suck work package, by bender workpiece is carried out bending, after finishing bending, electromagnet is cut off the power supply, finish whole working procedure.

Disk body 3 of the present utility model and outlet board 1 adopt Steel material to make, and the disk body 3 of steel has not only strengthened the hardness of disk body 3, in the service life of having improved electromagnet, also have good magnetic property simultaneously.Because the diameter of this wire hole 6 less than the diameter of disk body through hole 5, makes outlet board 1 have the effect of supporting magnetizing coil 4 simultaneously.The below of wire hole 6 is provided with terminal box 2 and comes the pass-out wire, and terminal box 2 also plays guardwire and the effect that is connected wire simultaneously.The packing material 7 of the gap location that magnetizing coil 4 and disk body hole are 5 adopts the epoxy resin filling with good heat-resisting, fire resistance.Packing material is magnetizing coil 4 fixedly, prevents that magnetizing coil 4 from rocking or walk, and improves the stability of electromagnetism.Bender of the present utility model is work top with the upper surface of electromagnet, this bender encloses the upper method that adds magnet excitation that adopts of design online with electromagnet, bender of the present utility model is reached more than the 30000N with the holding force of electromagnet, be more than 3 times of traditional electrical magnet.The principle that the utility model utilizes hot-wire coil to produce magnetic field will be treated the bending workpieces sticking on workbench, utilize fixing to workpiece of magnetic, save original pressure beam, simplify the structure of bender, be convenient to lifting, the bending of large-scale workpiece.

The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
