SU6428A1 - Method and device for inserting foals into the mold - Google Patents

Description

The proposed method of inserting wire into a mold is that through the end of the mold it is machined

1, the hole in the model is inserted into the cavity & tzhi / installed over or

 ; Under the flask model, where it enters / into the receiver, holding or simply supporting the wire, the end of which, after cutting it with scissors hidden under the model's surface, becomes a foal ./;,

For the implementation of the proposed method serves as a device shown in the drawing, where figl depicts a vertical section of the device, fig. 2 is a vertical section of a flask with a clamping device, fig. 21 is a horizontal section of the jig; FIG. 3 and 4 variants of the receiver (stop) and FIG. 5-consecutive operations of the proposed adjustment during the operation of the machine with the lower pressing.

The draw is a straight piece of wire 1, fixed in a special receiver on the binding 3 flasks 4 (Fig. 2). Shl Pok has no colt, but in spite of this, she can neither surrender nor warp, so hold her receiver in. which she got into the moment of formation of the wire, through the hole 7, from the surface of Yodioli 6, which lies on the plate 5 (Fig. 1).

The colt 1 was cut off from the wire 2-2 with scissors, hidden by iodine on the surface of the model, with a fixed knife 8 and a knife 9 {working from any mechanism.

Below, on the slider 10, a vise is arranged movable in a vertical direction, which in a timely manner seizes or releases the wire 2-2 when an appropriate mechanism is applied to them. The transmission system from this central mechanism to the jaws of every vice is the same arbitrary. The drawing shows a diagram of a spigot with a rotary sponge P, attached to the sponge 12 with the help of a pull rod 13. The movement of the slider 10 can occur from the lever 14. Still below are fixed vices 16 that are usually used for wire products, through which the wire can be dragged upward, since then their compression is weakened by the hubok pressed by the spring 17.

On 1tlitu 5 or on covering

-. its pod box 22 is placed in a flask L, which is so centered that over the holes 7 of the model b there are stallion receivers fixed on bindings 3 or near the walls of the flask. The receiver serves as a foothold for the foal and for support — so-so-rebeyka — not — folded — on its side / The designs of the receivers can be extremely varied / dependent | 1 on the molding conditions. FIG. 1. shows a receiver made in the form of tides 18 and 19 to the binding 3. In the tide 18 there is a funnel-shaped opening, continued by the groove 20, against which there is a spring 21 (Fig. 1 and 2).

When the end of the wire is 2-2 on the jl. u goes at the level of the cut plane | I of scissors 8-9, which happens fi every time after cutting the foal inserted in the previous flank, the mobile vise is in the lower position (Fig. 1). The vise seizes the wire and begins to rise, pulling it through the fixed vise 16, where it comes from the straightening rollers (turned on

- 7; , , drawing), / 4a "and applied 1 t €. in the state-owned and other machines. Scissors 8-9 freely pass wire 2-2 to the top. Its end passes through the hole 7 of the model, gets into the hole of the receiver, passes through the groove 20, spin 21, thanks to its twisted shape, and reaches the thrust

tide 19. At this point, the vise stops in the top position (dotted line 15) (Fig. 1). Their jaws open and the vise then returns down, but the wire cannot, as it is held by the fixed vise 16 (Fig. 2).

(The movable vise is not necessary to be controlled from the central mechanism, it is possible to have a self-gripping vise, like | 1b, but their work is less clear).

Then, cutting the wire with scissors 8-9, after which the knife 9 returns to its original position, clearing the way for a new wire pass.

Flask packing is done in the usual order-by-hand or machine. When the molded flask is removed from the model plate, the free ends of the foals come out of the holes 7. The foal cannot fall out of shape, even if its grip to the ground is not large / I / Ipy the gum 21 presses its groove 20. This type of receiver. use with relatively short and thick foals.

A variant of the receiver of the same type represents the finger 23, screwed into the gaiter rib perpendicular to the plane of the model plate (Fig. 3). At its end there is a small beard 24 with a hole, further there is a groove 25 and an emphasis 26. The small beard 24 may be absent, and the receiver begins with a groove. In this case, the spring holds the foal not so securely, but the possibility of clogging is less.

In some cases (thin wire and comparatively long foal) you can do without a spring. Such a receiver is a hook 27 screwed into the flask cover (Fig. 4). The draw goes through hole 28 and rests on pad 29, where a recess or notch can be made. The stall is prevented from falling to the ground.

It is useful to use a wire that has been passed through, knurled rollers to roughen it.

When working without a spring, you can fight the same way without passing the foal through the receiver's hole, putting it in the cover and covering the flask, while the ground will support it from all sides. If tape is used instead of wire, the latter is useful to give a grooved profile.

It is not at all necessary to insert the foal before the flask is filled with earth — it is sometimes more convenient to pierce it through the ground.

In the drawing, model plate 5 is depicted in the form of a movable pressing plate of a molding machine “with the bottom pressing. She walks in the bottom box 22, which, in the case of applying the proposed method to the specified machine, is a support for the fixed vise 16. The sequential operation of such a machine, in combination with the machine insert of foals, is shown schematically in FIG. five.

I.-Model plate above (at the level of the face of the flask). Movable vice in the lower position (relative to the model plate). The end of the wire at the level of the opened scissors. It puts on empty flask.

Ii. - Model plate at the top. The vise rose to the top position. The end of the wire reached the stop of the receiver.

III.-Model stove lowered to its lower position.

IV.-In the flask poured ground. Above the press cover.

V.-Model plate. Up and condensed the ground. The grip was lowered (which, however, could have happened at 11 or IV operations).

VI.-Scissors cut off the foal.

When the flask is ready, the scissors will open, restoring the initial state.

The subject of the patent.

The method of inserting the foals into the mold, characterized in that the end of the wire or tape is inserted into the cavity placed above (or under) the mold box through a particular hole in the model, is held or simply rests on the receiver arranged in the flask / and after cutting hidden under the surface of the model with scissors becomes the colt.

2. A device for carrying out in paragraph 1 of the method of inserting foals into a mold, characterized by the use of a lever vice 11-14 (Fig. 1) / reinforced in the slider 10 of the sub box 22 and inserting the wire 2 through the hole 7.b model b Flasks 4, where the end of the wire is held using a clamping device 18-21 (Fig. 2) or an emphasis 24-29 (Fig. 3 and 4), after which it is cut off using scissors 8-9 installed under the model wall (Fig. 1 and, than fixed movable vice 16 with a spring 17 is installed under said movable vice 11-14,
