Description

Image: stantion refers to the field of stacking, in particular to threading threading and he head and the head.

A machine for threading with a mechanism for opening a thread-cutting head, known as a yoke with a yoke and acting through a rod and having a fist mounted on it with a bar: oh carrying the workpiece is known.

 orders | These machines do not provide for threading different sizes.

In the proposed machine, for a cut: 1: and threads of different sizes, the opening mechanism is made in two levers fixed on one front axle shaft, one of which is connected through a threaded coupling with a head clamp, on the shaft with the possibility of permutation and is connected with the power element. This, for example, the spring-loaded pusher g, a tooth is fixed on the second lever, interacting through the swivel and spring-loaded stop with the fist mounted on the capacity of the nepecTaiHOBKiH.

FIG. 1 shows the proposed machine, a general view; in fig. 2 - section Io A-A on fit. I; in fig. 3 - the mechanism of opening, adjusted for instant opening of the head in the position “the head is closed; in fig. 4 - the same, in the position of “the head is open; in fig. 5 - Mechanism. Uncover, adjusted to open the head at a speed determined by the speed of the working nodal box and the head is closed; on . b - the same, in the new “head is open.

On the frame / machine to form a thread, the headstock 2 is not necessary, with the thread-forming head 3 fixed on the spindle.

A carriage 4 with a clamping device mounted on it, a device 5 for mounting and securing the machined 1-product ii is movably fixed on the guide posts. On the 1.

A bracket 7 is mounted on the butt-end of the headstock, on the axis 8 of which there is a hanger .9 covering the head 5 n connected to the outer ring of the head and two fingers W mounted on the side walls of the clamp 9 iHa p entering the annular groove on the outer side rings.

On the other hand, the collar 9 by means of hinges // II 12 II of the threaded sleeve 13 is connected to the lever 14. fixedly mounted on the rotary shaft 15, located in the ladder} 6 of the bed.

On the same shaft 15, a double-arm lever 17 is fixedly mounted, one end of which is connected with the push rod 19 by means of the hinge 18 to the pushrod 19. The free end of the pushrod 19 is provided with a buffer 20 and is in the support 21, which is made of glass, and installed on the machine

possible axial movement. Inside supports 21 us.yozlei alurtizator 22.

In, the outer end of the support 21 rests on the compression spring 1 1-3, the female ram 19 abutting its own second: the eye of the barrel 24, sitting on the thread of the ram 19.

The second two-arm lever 17 has a deep longitudinal groove 25 through which the rod 26 controls in the longitudinal direction of the release: both the opening and closing of the thread-forming head and the axis 27 in the transverse direction, carrying in its middle part the hardened tooth 28.

On 1st floor, on both sides, 77, are installed with the possibility of stopping the stop - left - 29 and right 30.

On the staple 26 there is also a fist 31, which is used for acting on the roller 32 of the Bolt 33, sitting on the shaft 34 and equipped with a tooth 35 on one side and a spring 36 on the other and an adjustable Vinto stop. 37. In the middle part of the bar, two more stops 38 and 39, which are located on both sides of the arm 40, are mounted with the possibility of stopping. They are still fixed on the KgipeTka 4 and provided with an opening (slot) through which the bar 26 passes freely.

At the end of the rotary shaft 15, the handle 41 is manually operated and opened and closed by the thread-cutting head.

A carving machine, if necessary, can operate in the mode of opening the thread-forming head, or open the head at a speed due to the working feed rate. In both cases, there should be an obechopech, the corresponding paste-building installation.

The adjustment of the machine on the cutting-edge opening of the thread-forming head is performed as follows.

Grossline: handles 41 through shaft 15, lever 14, clutch 13 and collar 9 NDT cover the thread-forming head. In this way, it pushes the lever 17 fixed on the shaft 15, turning back, cocks the spring 23 and, at the end of the rotation, the fi x is locked in the extreme position with the H01 by means of a turning stop 33, which carries: at the end a tooth 35, into which the spring acts 23, the tooth 28 of the rotary lever 77 abuts.

In this position, replacement of deforming barefoot can be made. This means; the coincidence of the 10-gauge 10 of the collar 9 with the annular groove of the outer ring of the closed thread-forming head is ensured by adjusting the threaded mufta 13.

The closed thread-forming head is equipped with an installation for the secondary stop 39 for moving the caretch 4 to be installed, in the initial position of the carriage 4, which ensures convenient loading of the parts and .М111.

A knob on the anvil 31 on the pole 26 relative to the roller 32 determines the moment of opening the head.

The stop 30 is installed from the stop 29 on the distance, by the stroke of the length of the stroke of the end of the lever 17, and the opening of 1-tin.

The position of the shock absorber 22 relative to the buffer 20 is adjusted by moving the support 21. The force of the opening of the shaped head of the device is increased by the nut 24.

It is installed in the device 5.

Nris moving carriage 4 forward proskhod; 1t. Cutting. On the workpiece. The length of the cutting is determined by the stop 38. The carriage of the brace 40 is pressed against the stop 38, which is variable from 26 to the SITTING on the fist. The fist 31 presses the roller 32, turning the bounce 33 around the axis 34. At the same time, the tooth 35 jumps off the tooth 28, releasing a rych.g 17, which rotates the shaft 15, rych.g 14 and a clamp 9 under the influence of springI1Ny 2-3. instant disclosure of the head.

Adjustment of the machine on the mode of opening the heads with the speed determined by the speed of the working feed is made by setting the unor 30 to the end of the lever 17. This should ensure a minimum gap between the head of the lever and the end of the stops 29 and 30 With the nut 24, the spring is 23, and the adjusting screw 37 rotates the stop 33 on the axis 34 and the tooth 35 of the stop 33 is engaged with the tooth 28 of the lever 17. When working in this mode, the valve 4 of the stem 40 pushes the stop 38, by moving the pole 26 with seats on it.
