Description

Known machines for attaching the bottom of the shoe to the nails.

The described machine, in contrast to the known ones, is equipped with a mechanism for the manufacture of nails of various lengths in accordance with the thickness of the fastened parts. This mechanism is made in the form of dies for the formation of the head and the tip of the end and an adjustable stop mounted on a spring-loaded anvil and interacting with the rod connected by a lever with a gear rack with rollers feeding the wire for the nails.

FIG. 1 schematically shows a general view of the machine; in fig. 2 is a nail manufacturing scheme.

All mechanisms of the machine are driven from a block / cams driven by an electric motor through a gearbox via a belt transmission 2.

Between the sleeve 3 and the stop lever 4 with the anvil clamped fastened portion of the bottom of the shoe; a size corresponding to the thickness of the bottom of the shoe is established by the lever 5.

When the cams rotate the cams, the roller 6 of the lever 7, which is connected at one end with a spring-loaded rod 8, with the spring 9, is lowered into the recess 10, and the rod 8 moves up to the stop of the adjustment head // into the sleeve 2 fixed on the lever 5; when the adjusting head L is moved upwards, the length of the bending part of the nail increases, and when moved downwards it decreases.

The other end of the lever 7, when lowering the rod 8, moves upwards and carries the gear rack 13 attached to it kinematically interacting with the ratchet wheel M, which freely rotates on the pinion of the pinion gear 15 as the rail 13 moves upwards. When the rail 13 moves downward, the ratchet wheel 14 engages with the roller of the gear 15 and turns it at a predetermined angle.

The gear 15 is engaged with the gear 16 of the roller 16 and rev. No. 97853-2 -.

sharpens the latter by the same amount, and with it the nails will be fed to the required length and for nails, which is pressed to the grooved groove of the roller 16 by a driven roller (not shown in the diagram) equipped with a corresponding groove.

The matrixes 17 of the mechanism for making nails receive movement in a horizontal plane from the main shaft of the machine through levers 18 swinging from the action of the corresponding cams of block 1. Matrices 17 clamp the end of the wire and feed it under the shearing knife 19, then under the hammer mechanism to form the nail head and then under the hammer mechanism for driving a nail.

Under the action of a spring (not shown in the diagram), the cutting knife 19 fits close to the wire 20, between the dies 17 and the guide sleeve 21. Then, when the slide 22 moves, driven in the horizontal plane from the cam block 1 and connected to the sleeve 21, measured The end of the wire is cut by the knife 19. In this case, the slider 22, by means of the guide sleeve 21, moves the wire to the pliers 23 to form a sharpening point.

The hammer 24, mounted on the base 25, mounted in the slider 22, moves to the dies 17, after which it is directed downwards by the lever 26, which oscillates from the block / cams.

When the hammer 24 moves down, the latter forms a nail at the cut wire billet sandwiched between the dies 17. At this time, two levers 27 under the action of the corresponding block cams / allow the pliers 23 to move horizontally to sharpen the end of the wire for the next nail, after which the nippers unclench springs (not shown in the diagram).

Upon further movement of the slider 22, the base 25 moves with it, and the hammer 24 takes up position above the dies 17. At this time, the dies 17, under the action of the spring, expand and the finished nail passes into the sleeve 3, which is in contact with the bottom of the shoe. Hammer 24, through the base 25 of the lever 26, receives a vertical downward movement and clogs the nail, which passes through the fastened bottom of the shoe and, falling on the anvil of the horn-support 4, bends on the inside of the insole.

At the time of nailing, the levers 27 re-compress the nippers 23, which, by means of corresponding protrusions and a groove, perform the cutting operation of a burr at the molded blade at the upper end of the wire for the next nail. The movement of the molded end of the wire to the nippers for deburring is performed by the slider 22.

The mechanism for depressing the thrust lever 4 operates from the rod 29, which is connected to the pedal 30 and is moved in the vertical direction from the block / cams.

The roller 31, periodically turning at a certain angle, advances the bottom edge of the shoe-to a predetermined rod, and its advancement occurs at the moment of depressing the stop lever 4. In this case, the rotation of the roller 31 is carried out as follows.

Using a lever (not shown in the drawing) associated with the block / cams, the rail 32 moves in a horizontal direction and, in engagement with the bristles 33 interacting with the ratchet wheel, rotates the shaft on which the drive bar 34 is mounted. , being in engagement with the bristles 35, transmits the rotation of the roller 31.
