Description

(54) C-TELAZH FOR FILING A WIRE MATERIAL IN HEATERS

one

The invention relates to the mechanization of technological processes and can be used to mechanize the supply of round rods to heaters and to issue heated rods for subsequent technological operations, such as winding spiral springs, cutting the rod into dimensional parts and other operations.

A known automated rack with a pneumatic agitator, comprising an inclined platform on which the tie rod, pneumatic actuator, pneumatic drive frame, frame and stop plate, cutting discs rotating from the cylinders, and drive rollers 1 are placed on the crane.

However, the rack is characterized by unreliable operation, since the bar to be cut-off can slip the stream of feed rollers by inertia, because there is no reliable stop. In this case, the bar is removed along the stream, which is not always possible, and the issuance of the bar is not adjustable in height.

The closest in technical essence to the present invention is a rack containing an inclined storage with stops, two-arm lever shut-off devices, one

the shoulder of which, facing the workpieces, is made in the form of a sector, and the roller conveyor 2. However, two pneumatic cylinders do not provide synchronous operation of the lever shut-off devices and the rod may not get into the stream

 the roller table, the issuance of the rod is carried out only along the stream, which is not always possible, for example, when winding spiral springs in a hot condition, where the heated rod lies on the contact electric heaters and cannot move along them in the longitudinal direction, as a result of which the said rack for feeding the bar in the transverse direction would require an additional mechanism with an actuator, since the lever shutoffs

 they just drop the bar and cannot remove it from the stream. At the same time, the live rolls are not adjustable in height, which limits technological capabilities, for example, winding springs of various sizes requires

Claims (2)

20. adjustment of the output bar in height and its free transverse movement along the roller table. In addition, the adjustment of the lugs is separate, which creates errors and inconvenience in operation, besides there are no lugs at the stream of feed rollers and the rods can slip through it by inertia. The aim of the invention is to increase the reliability of the rack. The goal is achieved by the fact that in the rack containing an inclined drive with stops, two shoulders lever cutters, one shoulder of each of which facing the blanks, is made in the form of a sector, and the roll table, the other shoulder of each lever cutter is L-shaped, the roll table is installed an inclined storage device, and also provided with a sectional lodgment with locks at the ends installed along the rack from the L-shaped arms of the lever snapping-down devices that pass between the sections of the cage. The stops of the inclined storage device are adjustable from a common drive. The roller conveyor is height adjustable. Clamps are made in the form of fork arms. FIG. 1 shows a rack, a general view; in fig. 2 shows section A-A in FIG. 1. The rack for feeding the bar material to the heaters contains a base 1, on which the inclined storage device 2 is fixed, and 3 cutters 4 rotatable from one power cylinder 4. One arm of the lever cutters 4 is made in the form of a sector and interacts with round bars 5, and the other is L-shaped and interacts with a thermally insulating lodgment 6, fixed on the base 1 and closing from above by a thermally insulating casing 8, which is rotatable from the power cylinder 7. On the inclining drive 2, the stops 9 are mounted, handles 10 on a scale of 11 to the required diameter of the rod 5 using screw pair 12 and a system of levers 13, and end plate 14 for aligning the ends of the car. Under the accumulator 2 a lifting roller table 15 is mounted, equipped with a counterweight 16 and an actuator 17. To securely lay the bars 5 into the heaters 18 and into the cradle 6, at its ends on the base 1, latches 20, rotatable from the power cylinders 19, are mounted, made in the form of arms with a fork at . Outside the rack is closed by a casing 21. The rack works as follows. The bar material is placed with a crane onto an inclined storage device 2, rolled into a row and leveled along the end plate 14. Align stops 9 on a scale of 11 to the required bar diameter 5, i.e. so that the cut-offs 4, when rotated upward, seized only one bar 5. The command from the control panel turned the lever-cutters 4, lifting the bar 5, which rolls down to the L-shaped ends of the cutters 4 into the heat-insulating lodgement of the bi-heaters 18. They lower the levers - locks 20 and adjust The position of the rod 5 in the cradle 6 and in the heaters 18. The thermo-insulating casing 8 is closed, the latches 20 are raised, the heaters 18 are turned on. After the bar 5 is heated to the desired temperature, the heaters 18 are turned off, the thermo-insulating the cover 8 is opened, the cut-offs 4, turning in the opposite direction, take the bar 5 from the cradle 6 and from the heaters 18, it rolls down onto the non-driven roller conveyor 15 under the inclined drive 2, from where it is fed to the next operation. The cycle is over. The rack allows the bars to be reliably supplied to the heaters and removed to the roller conveyor, while ensuring minimum dimensions of the rack. Formula of invention 1. A rack for feeding bar material to heaters containing an inclined storage device with stops, two shoulders lever cut-off devices, one shoulder of each of which, facing the blanks, is made in the form of a sector, and roller conveyor, characterized in that the other shoulder of each lever cutter is L-shaped, the roller table is installed under the inclined drive, and is also equipped with a sectional lodgement with locks at the ends installed along the rack from the L-shaped arms of the lever compartments Catel extending between the sections of the cradle. 2. A rack according to claim 1, characterized in that the stops of the inclined storage device are adjustable from the common drive. 3. A rack according to claim 1, characterized in that the roller conveyor is height adjustable. 4. The rack according to claim 1, characterized in that the latches are made in the form of fork arms.
