SU53825A1 - Automatic second hand machine - Google Patents

Description

Automated machines for making second-hand carving by carving are known in which a series of consecutive dies and a feeding device are used.

In the proposed automatic machine, instead of a separate punch for punching holes in the needle for the tube - footer, the tube itself is used; the riveting of the latter, in order to keep it in the arrow, is made by the punch while simultaneously carving the arrow itself.

In FIG. 1 shows a general view of an automatic machine for making the second hands; FIG. 2 - a device for feeding the tape; FIG. 3 - side view of it; FIG. 4 - a mechanism for feeding the tube; FIG. 5.5 incision of it; FIG. b-matrix and stamp for inserting the tube-footer in the tape in the section; FIG. Figure 7 depicts a punch for carving an arrow and flaring a tube-footer; FIG. 8 is a cross-section of the core according to FIG. 7; FIG. 9 is a section through CD of FIG. 7; FIG. 10 depicts a matrix for carving an arrow and flapping a tube-footer; FIG. P - section of the matrix in EF FIG. ten; FIG. 12 is a section through MN of FIG. ten.

On a common frame 7, three sliders are located in the guides for the production of sequential manufacturing of the second hand, receiving movement from the crankshaft 5, located in the upper part of the machine.

The slider 2 feeds the cut off tube and punches a hole in the tape with it; the slider 3 performs the operation of carving the arrow and flares the tube in it. The slider 4 serves to feed the tape.

The tube is fed by a feed mechanism 24 (Figs. 1, 4 and 5), which is mounted on the frame of the machine. Ratchet 10 is provided with end and outer teeth; the latter are engaged with the dog 12, mounted on the slider. During the course of the slide, the dog 12 rotates the ratchet 10 by one tooth; at the same time, the ball 13 hits the top of the ratchet end tooth and transmits the pressure through the clip 14 to the plate 26, under which the tube passes from the drum 6 (Fig. 1); the plate clamps it, the movement of the tube stops, and the slider, continue to go up, picks up the die inside (see Fig. 6), the end of the tube

which is adjusted by end-teeth, tapering toward the center, and a ratchet seated on the eccentric sleeve 9 (Fig. 5), the offset of which determines the length of the tube. The stamp (FIG. B) in which the end of the tube is clamped is

the vice of two sponges 8 VI 9.

Inside the vise is a knife 7 with a hole for the tube, as well as in the sponge 9. When the tube has reached the desired length, the vise is shifted by means of a perpendicular crankshaft 23 passing through the knife and one vise sponge. When the slider moves down, the rake actuates the knife, which cuts the tube with lateral movement and serves as a stop for it when piercing the tape. Down, slide the slider through the matrix 25 (FIG. 6) into the tape in the hole with a clamped piece of tube and leave the last one in it.

The inserted tube moves to the middle slide, the stamp (fig. 10) of which is in the shape of an arrow with a hole for the tube; A thrust needle 21 (Figs. 11 and 12) passes inside the hole, which serves to push out the arrow after carving and flaring. The slider lowers the die, the pipe into the hole of the shaped punch 20, which makes an arrow carving, and at the same time the lever / 5 connected to the connecting rod / b, extends the expansion plug from the die // (Fig. 1, 8 and 9) which, having flared the tube, goes down, freeing a hole in the matrix for the passage of the arrow. When the slider is raised upward, the thrust needle 21 of the stamp using the lever 17, interacting with the ejector 22 and driven from the cam on the disk 18 (Fig. 1), leaves the punch 20 (Fig. 10) and throws the finished arrow out of the die 27 (Fig .7).

The feed is made as follows. Slider 4, lowering down, roller 28 presses on the carriage under which the ribbon passes, and the latter is clamped; upon further lowering of the slide, the roller spring compresses and allows the protrusion 29 to approach the carriage 30, the bevelled edge moves the latter to the right side, moving the belt along with it. After the slider is raised, the carriage 31 returns to its original position. , with arrow carving (slider 5). The slider 4 is raised at this time. When the slider 2 and 5 are raised, the slider 4 is lowered and feeds the tape.

The subject matter of the invention.

Claims (3)

1. An automatic machine for making seconds of hand by carving, consisting of a series of consecutive dies and a feeding device, characterized in that the tube-footer is used as a punch for a tube-footer, for flapping the end of which, in order to keep it in the arrow, a counter-punch was used. 2. In the machine tool according to claim 1, a slider is used with clamping jaws for a punch in the form of a tube, equipped with a feeding device consisting of a fixed clamp 14, which serves to hold the tube when raising the slider and is controlled by a ratchet 10 and a pawl 12. 3. In the machine tool according to claim 1, use a tape feeding device consisting of a carriage that interacts with the roller 28 of the slider 4 to press the belt during the feeding process and with the bevelled protrusion 29 of the slider for translational movement. to the author's testimony of K.
