Description

one

This invention relates to automatic heating devices.

Known induknionny heater containing the store with a sloping table, loading device of the gate type, the upper and lower heating heads with inductors, a cut-off device, a supporting comb. However, this heater is applicable for heating billets of wide sizes.

The purpose of the invention is to carry out the loading of inductors by nolosovy billets of various sizes in width, length and thickness. This is achieved by the fact that the inclined table is pivotally fixed with the possibility of its movement, the loading device is equipped with noskom pushers arranged alternately with the cutter stops in the slots of the supporting comb, and the heating heads are made with guides and fixed on horizontal rods.

On the fit. 1 shows an induction heater; in fig. 2 — node I in FIG. one.

On the housing / there is a magazine 2 with an inclined table 3 for blanks 4, a loading device of a slide type 5, made in the form of a frame, a cutter 6, a supporting comb 7 with slots and a transfer device 8 with a connecting rod 9.

Four round hollow rods 10 are mounted on the wall of the cornea / are mounted. On the two upper rod members there are mounted heating heads // for displacement, each of which includes inductor 12 with section 13, with guides 13 beneath the workpiece 4, provided with a cut-off support M, a locking device ( on hell, not shown) and the mechanism for adjusting the head 15 but the thickness of the workpiece. On the two lower rods, the heating heads 16 are arranged for movement, each of which includes an inductor 17 with an I 18 guide under. billet 4 and locking device. The inclined table 3 of the store 2 with its upper part is mounted on the axis 19, and the lower part

associated with a rotary eccentric shaft 20.

On the working surface of the inclined table

there is a stand-up stop bolt 21 for

proper laying of long blanks l

removable stop collar 22 for short workpieces. On the upper plane of the frame of the loading device 5, three pairs of nlosky pushers 2 are fixed, the working profile of each of which has a bearing surface of 24 n pushing tooth 25.

The workpieces are placed on the working surface of the table on the edge up to the stop by the ends of the thrust collar 21 or 22, while the bottom blank rests on the supporting surface 24 of the pushers 23 of the loading device 5. Cutter 6

made in the form of a bracket 26 and speakers protruding from the supports 27. The profile of each support is made in the form of a yukoba, passing under the bottom blank and having a front tooth 28 with a skew. The cutter is equipped with a device 25 for its movement.

An induction heater for heating the strip blanks operates as follows.

The loading device of the spherical type 5 from the transfer device 8 with the power of the rod 9 performs the swing movement. During its working stroke, the pushing teeth 2 of the pushers 23 grip the lower billet from the magazine 2 and push it between the guides 13 of the heating heads 11 and the upper Bentness of the support comb 7, pressing this billet down the bevels downslope 6 down the bevels 26 along the bevel 26. In addition to the lower one, they are prevented from moving by the cutting stops 14 of the guide / 3 heating heads 11. When the loading device returns, the workpiece is kept from sliding down by the stop teeth 28 of the cutter 6, which: and the workpiece above the stops 27 is lifted to its original position with the help of TOOL 29. The E-return end of the loading device 5, the package of blanks, moving along the inclined table 5, sits on the supporting surfaces 24 of the plungers 23 and the feed cycle of the blanks is caught at a given pace. The loading device has a constant stroke regardless of the width of the workpiece. When included in the network T.V.CH. The inductors 12 and 17 of the billet, which are passed between the heating heads, are heated to the required temperature and are given out one by one for the next operation. The adjustment of the heater to the thickness of the workpiece is performed by the adjustment mechanism 15, which raises and lowers the heads,

i.e., it establishes a necessary (depending on the thickness of the workpiece) gap simultaneously between the inductors 12 and 17, between the guides 13 and 18, between the cutting edge 14, the guides 13 of the heating head And and the support comb 7. After installation, the head is fixed by a locking device. The guides 18 of the heating head 16 are not adjustable and are flush with the top.

the plane of the supporting comb 7. After moving along the rods 10, the lower heads are fixed with a locking device. Adjustment of the heater across the width of the workpiece is carried out by raising or lowering the lower part of the inclined table 3 of the magazine 2, which turns in its upper part on the axis 19. This changes the distance between the working surface of the inclined table 3 and the squeezing stop 14 of the guides 13 of the head

1- The position of the inclined table 3 is changed by turning the eccentric shaft 20 at a certain angle.

Subject invention

Induction heater containing an inclined table magazine, a spindle-type loading device, upper and lower heating heads with inductors, a slam-shut, and a supporting comb, different in THAT, for the purpose of single-loading inductors with BAND blanks of a wide range of sizes in width, length and thickness , the inclined table is fixed pivotally with the possibility of its movement, the loading device is equipped with flat pushers arranged alternately with the cutter stops in the slots of the support comb, and the heating Body heads are made with guide arms and fixed on horizontal rods.
