Description

one

The invention relates to the manufacture of sleeves, having an outer protective metal braid and shielding copper braid, in particular shielding sleeves with a polymer tube, and can be used to prepare their ends for connection to the reinforcement.

A device for flanging is known comprising a central support element and a crimping punch 1 mounted coaxially with it.

However, this device does not provide good quality flanging.

The purpose of the invention is to improve the quality of flanging.

The goal is achieved by the fact that the device is equipped with a rotary body mounted on the crimping punch with a lead and a guide finger mounted on the supporting element, while the crimping punch is made in the form of telescopically mounted sleeves that interact with the hull leash and with longitudinal grooves that interact finger support element.

FIG. 1 shows the device, a general view in section; in fig. Fig. 2-5 sequential bend transitions of the braid of the end of the shielding sleeve with a fluoroplastic tube on the example of a circuit with three moving telescopic sleeves.

The device contains a sleeve 3 mounted in a rack 1 by means of a bolt 2 with a central support element 4 and a guide pin 5 mounted on it. On the sleeve 3 there is a rotary body 6 fixed from axial movement by a screw 7 and provided with a driver 8, between the central support element 4 and housing 6 is located flanging rtyaHcoH in the form of telescopic sleeves 9 with screw and longitudinal grooves.

The device works as follows.

Billet - sleeve 10 with sleeve 11 is put on the central support element 4 and with the help of a folding stop

5 12 is held against axial movement. Next, turn the housing 6 at a certain angle, while the lead 8 acts on the screw groove of the telescopic sleeves 9 and leads them into axial movement. The front part of the inside of the telescopic sleeves 9 enters the gap between the fluoroplastic tube and the copper braid, pushing the latter in the radial direction (Fig. 3). With a further rotation of the holder, the middle telescopic sleeve comes into play, increasing the angle of the bend of the braid. Then the outer telescopic sleeve comes into operation, bringing the angle of the limb to 90 (Fig. 5). The ends of the sleeves are combined in one flatness

The number of telescopic sleeves may be different, depending on the length of the perimeter of the bent-off sheath ring. To ensure consistent movement, the telescopic sleeves are made with screw grooves having annular and screw portions that are offset relative to each other around the circumference by design angles from the axis of the fixing grooves.

The use of the device ensures uniformity of otgodA braid around the perimeter of the bent cylinder, which

improves the quality of sleeves and increases productivity.

invention formula

A device for flanging the braid of sleeves, containing a central support element and a crimping punch mounted coaxially with it, which is equipped with a swiveling body with a leash and on it in order to improve the flanging quality. mounted with a guide pin on the central support element, while the crimping punch is made in the form of telescopically mounted bushes with screw grooves in contact with the leash of the body and with longitudinal grooves in contact

with finger support element.
