SU295593A1 - DEVICE FOR EXTENDING THE END OF A PIPE AND ASSEMBLY OF IT WITH A COUPLER - Google Patents

Description

The invention relates to the field of mechanical engineering, in particular to tooling for assembling and flaring.

The known devices for the same purpose, comprising a housing with an abutment located in it, a clamping element and a flaring head, do not impoverish the mechanized process of assembling the tube with the sleeve and flaring the tube end.

The purpose of the invention is to eliminate this drawback. This is achieved in that the firing pin is provided with a flaring nodnruzhineinoy sleeve for centering the coupling but the inner diameter and is mounted in the plunger, connected to said cylinder and unor vynolnen iodiruzhiiennyh as two sliders relative to the housing with the slots for coupling orientation is.hodnom iolozheiii provided with rollers, interacting with the pusher.

The proposed device is shown in the drawing.

The device consists of a body /, spring-mounted relative to the body, an adjustable stop for a tube in the form of sliders 2 with grooves 3, which serve to orient the coupling in the initial position, and rollers 4, pneumatic pressure washers 5 with an outer nozzle in the form of an elastic sleeve 6 at the end of the striker and a single pusher 7, centered on the striker and

having a hole in which sleeve 6 is located. The device also contains a clamp 8 for a tube. The spring surface of the pusher is performed by the profile with which roller 4 interacts. In the hole of the pusher there is a collar 9, limiting the leftmost and empty sleeve 6 and another collet 10, which limits the position of the spindle 5 relative to the mass of 7 pn. The pneumatic wound is rigidly connected to the rod // pneumo box. The device works as follows; 11m.

In the initial position, spring-loaded sliders 2 are collapsed and grooves 3 hold the assembled clutch 12. This clutch doesn’t fit into the groove on top of the hopper pack-packer (not shown) located just above the head and containing the clutches irimming under gravitational forces to each other.

In the same position, the windshield wrench 5 with the nozzle is in the extreme right position of P1I1. The tube 13 is fed to the unor at the end of the sliders 2 and the jaws are clamped 8. The pneumatic cylinder is turned on, the rod of which is left to the left but the drawing of pneumatic chambers 5 with the sleeve 6 and the pusher 7, due to which the sleeve with the tube is assembled.

coupling to the stop at the end of the tube. At the same time, the rollers 4 slide along the profile of the pusher 7, whereby the slide blocks 2 are consumed, releasing the clutch. In this position, the pusher 7 is in contact with the center with its internal cone. Prp further advances p: current 11 pusher pusches the clutch from sleeve 6 and simultaneously pushes it onto the tube as far as it will go into the jaws of the clamp 8. Prp long-distance rod movement // sleeve 6i TO; Icatel 7 stand in place, and the pneumatic caliper continue to move with a rod, razvalnovyvaet tube. The spring of the pusher is compressed until that time until the tore of the hammer 5 does not uirets into the collar of the 10 pushers. From this point on, the assembly and flaring operation is being pumped up.

During the return stroke of the rod, the impeller, the pusher and the coupling operate in reverse

sequence and become the original position.

Subject invention

A device for expanding the end of the pipe and assembling it with a sleeve, containing a cornus with an abutment located therein, a clamping element and a flaring head driven by, for example, an Inevmatich cylinder, characterized in that, in order to mechanize the process, the expanding head is provided with a spring-loaded sleeve for centering the coupling on the inner diameter and mounted in a pusher connected to the specified iHJM cylinder, and the mount is made in the form of two slots mounted around the body of the sliders with grooves for orientation of the coupling in the original position, provided with rollers, vzapmodeystvuyuschimp with a pusher.
