Description

The proposed wood copying machine, mainly intended for the manufacture of pads. In the schematic drawing of FIG. 1 shows a general view of the machine in front; FIG. 2 is a side view; FIG. 3 is a plan view; FIG. 4 is a view of the swing frame; and FIG. 5-13 details of the machine. The machine is provided with a frame C on the drive axis D (fig. 1-3, 5) carrying the axis, on which two cutting chucks 20 are located. Below the axis, in the frame C, there is a double screw DJ with right and left cut, corresponding to the cartridges 20.

Both the screw Z, and the axis Z) jj receive rotation by means of a corresponding transmission from the drive shaft (axis) D (FIG. 3). With the frame (7 articulated two levers Ci Ci, equipped with fork-shaped parts / (Fig. 8), serve to grip the trunnions of the nuts s (Fig. 1), moving but cut by the Vypta Dj and to grip the pins of the sleeves I (Fig. 1) on the bushings of the cutting cartridges 20. The arms c and Cj are used for axial movement of the cartridges by means of the rotating screw jbj.

frames C pa axis) are freely put on a 5-5-5G carrier lever K, the purpose of which is to change the transverse dimensions of the manufactured item according to the transverse dimensions of the model. This change is carried out by means of a permutation Wipti at the upper end of the lever and at its lower end by means of a head with a cruciform slit (r) (Fig. 5, 2), in which the axis r is set in different positions, bearing a freely mounted paired roller K .

To change the length of the item being processed on this model, a device consisting of a lever d (Fig. 4, 5, 9, 10, 11 and 2) is used, which is pivotally connected with frames C and K and connected in a certain place to the wing W (Fig. 13 and 1) by means of an arc (Fig. 12) provided with openings. The curtain is located on the lever djj, which is hingedly attached to the slide dj, which is worn with its end on the pin of the coupling G.

In the case that only one workpiece is required, screw D

together with the corresponding levers with and Cj is replaced by one screw

with only one thread, the lever system c, p djj replaces the fork rod, which is simultaneously connected with the nut s, frame K, and with the pins of the coupling M. of the incisal chuck 20. covered by frame K.

For the processing of blanks according to the finished model, the latter is laid between the 1 in. Scale of & JJ and fp and between the shninddel and & both I and I and 6j (fig. 3) lay the blanks in mutually opposing maneuvers, i.e. If, for example, the model represents a shoe-shoe and is installed between the centers with the toe to the left, then the blank closest to it is also set with the toe to the left, and the second, right-toe pair, respectively, the left and right double screw cuts T.

Due to the above-described adaptations, the model serves as a guide for moving the incisors and simultaneously both blanks are processed, as a result of which processing the product is an exact copy of the model.

The subject of the patent.

1. Wood copying machine designed for simultaneous processing of two blanks, characterized by shoveling use: a) Frame C (Fig. 4, 5, 1, 2, 3) carrying a DJJ axis with two chuck cartridges 20 (Fig. 1-6 ), as well as a double screw DI, respectively, with right and left cuts, and able to swing about the drive axis D, which informs the rotation to the indicated screw D and the axis D, with which frame, in addition, two

levers with Cj (Fig. 1, 2. 8), wrap around the forked parts of the nuts s on the thread of the screw J) and the axle of the couplings M on the hubs of the 20n cutter cartridges are suitable for axial movement of these cartridges by the action of the slices of the rotating inner of the D .Zi: (Figs. 1, 9, 10, 11, and 3), freely attached to the D axis and carrying the lever p, equipped, for the purpose of changing, with the same model, the transverse dimensions of the item being manufactured are permuted by the upper end of n on the lower-head with a cross-shaped slit Z (Fig. 5, 2). employee to be installed in it in different positions of the g axis, with a contact roll (ijp) freely mounted on it and c) devices for changing at this model, the length of the item being manufactured, which adaptation consists of a lever d (h Fig. 4, 5, 9-11, 2), which is connected in the required place, by means of the openings F of the arc (Fig. 12), with the link w (Fig. 13, 1) lever 2, in its queue fanged with a slider dj, put its end on the pin of the coupling M.

2. Modification of the machine described in paragraph 1 for the case of processing only one workpiece, characterized in that screw D with its corresponding levers c and Cj is replaced with a screw with only one thread, and instead of a lever system d. d, with / p, a fork-shaped rod connected simultaneously with the nut s of the specified screw, with the frame and with the studs of the coupling G of the chuck 20, covered by this frame K.
