Abstract

The invention relates to electrical engineering, in particular to cable technology. The purpose of the invention is to improve the quality of the curled products by reducing the length of the transition sections. The machine contains two swiveling heads 4, in which the rocker arms 10 are mounted. On the arms of the rocker arms 10, the twisting rollers 6 are symmetrically mounted, while the rocker arms 10 are connected to the elements 11 of the synchronization of rocker arms. This embodiment allows us not to stop the swirling rollers in the process of operating the machine and not to change the frequency of the wind (L and thus get a transition section of the minimum length. 6 Il.

Description

one

The invention relates to the technology of twisting long products, namely to SZ machines twisting cable products.

The aim of the invention is to improve the quality of the curled products by reducing the length of the transition sections.

FIG. 1 shows the SZ machine twisting long products, the general view; in fig. 2 and 3 show a kinematic diagram of a swirling head and the sequential position of its links in FIG. 4-6 - sequential schemes of the machine.

The SZ twisting machine of lengthy models contains the output sensors 1, the input caliber 2 installed in the technological sequence, two kinematically interconnected and with the drive 3 rotations swirl heads 4, each of which is installed in one plane along two guides 5 and two twisting 6 rollers , output caliber 7, gov 8 and receiving device 9.

Rocker arms 10 are located in each swiveling head 4 associated with rocker arm 10 synchronization elements 11. Turning rollers 6 are mounted symmetrically on the arms of the rocker arms 10, the axis of rotation of which is perpendicular to the axis of rotation of the heads 4.

SZ machine twisting long products works as follows

The curled article 12 is 1 according to FIG. 1. After charging, the drive 3 rotates the swirl heads and simultaneously drives the 8 and the receiving 9 devices, which remain on during the machine operation. At the same time, the cable product 12 has a constant speed of linear movement. During operation of the machine, both rocker arms 10 periodically rotate at a certain angle with the help of elements 11, which ensure synchronism of intermittent rotational movements of both rocker arms 10. When the beam 10 is rotated to the position shown in FIG.

When rotating the twisting heads 4 in the plane, the perpendicular p77219J

In this case, it begins to twist after the entrance gauge 2 in the right, and before exit gauge 7 in the left direction.

5 After the product A is filled with zones A, B and C (Fig. 1) twisted in the right direction, the rocker arms 10 rotate in the opposite direction and are set to the position

10 depicted in FIG. 3. In this position of the rocker arms, the cable product 12 passes freely between rollers 5 and 6 and fills A, B and C without receiving a twist.

15 After filling the zones A, B and C with the untwisted piece of the rocker arm 10, it is again rotated to the position shown in FIG. 2 and the cycle repeats.

20 In FIG. 4, 5, 6 shows successive patterns of operation of the SZ twist machine during one cycle of operation. FIG. 4 twisting rollers 6, coupled with the product 12,

25 made it twisting in zone A in the right direction, in zone B - in the left. In zone B, the product was not twisted and entered into it from zone A twisted in the right direction.

30 FIG. 5, the product 12, twisted in the right direction, filled the entire zone B and the front of the right twist approached the beginning of the zone B. In FIG. 6 after turning the rocker arms 10 to the position

35 ensuring the uncoupling of the twisting rollers with the product 12, the latter exited from the zone B with the right twist direction and entered the receiving device 9. The zone B is 40 with the accumulator and its length determines the size of the section of the product 12 twisted in one direction.

Since the twisting rollers during operation of the SZ machine twist does not stop and do not change the rotational speed, the twisting of the product 12 begins and interrupts in the short time required for the rotation of the rocker arm 10 at an angle of 10-20, and the transitions in which the product has a distorted pitch twisted or not twisted at all, have a minimum length.
