Description

The invention relates to the processing of metals by pressure and can be used in the manufacture of wire products, in particular in the manufacture of single fishing hooks.

A known method of manufacturing small fishing hooks, in which a workpiece in the form of a needle with a tip at the end is placed in the feeder and each workpiece is supplied to the conveyor of the machine, made in the form of two spiral screws rotating in one direction and fed into its turns to the cutting position, where it is cut into required length. Then, the operations of notching the beard, bending the underbody and forming a ringlet are performed.

The disadvantage of this method is the low productivity, since at least three different automatic machines are required for the complete production of the hook, and the automatic machines are loaded manually.

Also known is a machine for the manufacture of fishing hooks, including wire feed, straightening, notch, bevel bending, hook forming and mechanism for transferring the workpiece from position to position using vehicles made in the form of two spiral screws.

However, the known machine is designed for the manufacture of double hooks and cannot be used for the manufacture of other hooks, for example, single

fishing hooks, since the mechanisms for locating the workpiece and forming the tip cannot be unified, and the mechanism for forming a single hook and a double hook is different.

The aim of the invention is to increase productivity, which is achieved by creating a technological base in the first operation, which makes it possible to carry out further automation of the process and significantly reduce manual labor on loading and unloading operations. The method saves a large number of grinding wheels, since the formation of a tip is carried out by flattening, followed by trimming instead of grinding. The machine allows you to save production space, free up a large number of staff. A significant economic effect occurs due to the reduction of metal consumption, energy consumption and labor costs in the manufacture of the machine.

This goal is achieved by a technical solution that presents a new method of manufacturing single fish hooks, including straightening and chopping the wire, flattening it, forming a ring, cutting the beard and bending the hook, and also transporting between processing positions. New in the method is that the operation of forming a ring, which serves as a technological base, is performed on a wire of unlimited length, the operations of forming the tip of one hook and cutting the workpiece of another hook are carried out simultaneously at the same position with the workpiece unchanged. This method can be carried out by a machine for manufacturing single fishing hooks, including wire-feed, flattening, cutting, notching, bevel bending, hooking, ring-forming and transporting means placed on the base and kinematically connected by means of a camshaft; The difference between the machine and the new method is that the ring-forming mechanism consists of a bracket mounted on the rod, mounted in the bracket of the central correction rod. The central mandrel bar is mounted to move vertically from the camshaft. A rotary sleeve with a bending protrusion at the end is placed on the mandrel bar. The sleeve is rotated from the rack and pinion gear and the lever associated with the camshaft. A guide strip is mounted at the end of the bracket, fixed to the upper plane of the bracket above the central mandrel bar. The mechanism for the formation of spikes and segments consists of a bracket mounted on the frame, on which a drive adjustable vertical cutter is mounted, and mounted on the base with the possibility of reciprocating movement

carrier carriage of a horizontal cutter mounted on its upper plane, mounted to interact with a vertical cutter, and a cutting disc knife mounted on its lateral face.

The method is carried out as follows.

The end of the wire of unlimited length is passed through the straightening mechanism,

0 then the feed mechanism feeds it to the conditioning mechanism. After preparing the wire, it is pushed through the guide sleeve into the b-mechanism for the formation of the tip and ring, where the protrusion on

In the 5th rotary sleeve, the end of the wire is rolled around the central shaft to form a ring. The carriage with a horizontal knife, in cooperation with a vertical knife, forms the tip of the hook and simultaneously cuts off the workpiece from the wire, and the circular knife cuts off the excess part of the flattened area, preparing the end of the wire for the next ring. The central rod is recessed, and

5, the transport turns tighten the workpiece into the slit of the longitudinal bars, where the workpiece is fixed on the ring.

In FIG. 1 is a kinematic diagram of an automaton; in FIG. 2 - formation mechanism

The single hook machine includes a drum for placing

5 coils 1 wire, wire feed mechanism 2, wire straightening drum 3, wire flattening mechanism 4, pinning and ringing mechanism 5, transport screws 6, drive 7, mechanism

0 8 notch barbs, mechanism 9 bend hook. On the lower plane of the plate, supports are mounted in which the camshaft 10 with cams rotates. The tip-forming and ring-forming mechanism 5 consists of a stand 11 on which a guide sleeve 12 and an adjustable vertical cutter 13 are mounted. On the base 14 there is a carriage 16 on which a horizontal adjustable cutter 16 is mounted. To the side wall of the carriage 15

the blade knife 17 is fastened. A gear roller 19 is mounted in the rack 18, inside of which there is a shaft 20, on which the spring 21 presses. There are guide rails 22 above the rack. There is a rack 23 in the groove of the rack 18, on the end of which a lever 24 is fixed. On the lower plane of the camshaft mount plate 10, a swing support of the arm 25 is mounted.

The electric motor through the drive 7 transmits the rotation to the camshaft 10 with cams, the movement of which through the levers is transmitted to the hook forming mechanisms. The feed mechanism 2 moves the wire from the bay through the straightening drum 3 to the flattening position. The wire is then pushed through the guide sleeve 12 into the tip and ring forming mechanism 5. Flattened

the bottom part of the wire falls between the blades of the horizontal cutter 16 and the vertical cutter 13, the cut of which forms the tip of the hook. At the same time, the second end of the workpiece is located in the lumen between the central shaft 20 and the protrusion located on the end of the pinion roller 19. When the pinion shaft 19 is rotated from the rack 23, a ring is formed using the lever 24. Under the action of the lever 25, the central rod 20 is recessed, compressing the return spring 21, and releases the ring of the workpiece, which is picked up by the transport screws 6 and transferred to the next position, where the beard is notched by mechanism 8. The circular knife 17 cuts off the second half of the cut, forming the necessary end face of the workpiece.
