Abstract
The utility model relates to a pipe end necking-down apparatus, which can make the end of the thin wall metal pipe into a cone, being applied to the installation and connection of thin wall metal pipes. The utility model is composed of a machine body (1), an elasticity cover(2), a propulsion loose piece (3) and an actuating mechanism (4) which can be a hand-operating mechanism or a pneumatic mechanism.
Description
The utility model relates to a kind ofly can be processed into the end of thin metallic tubd conical pipe end shrink mouth device, is used for the installation of bonding thin wall metal pipeline.
In " connection of thin-wall stainless steel and cutting method " (application number 00130741.X) patent of my application, during installation, require pipe end is processed into taper shape earlier, carry out bonding with the pipe fitting that has with tapering then.But in the market, Shang Wuke is for the isolated plant that can finish the tapered processing of pipe end that directly adopts.
The purpose of this utility model will provide a kind of pipe end shrink mouth device exactly, is used for specially the end of thin metallic tubd is processed desired taper shape.
The purpose of this utility model is achieved in that in a device that is made of body, elastic sleeve, thrust loose piece and actuating unit, being positioned at the elastic sleeve of body, is to match with internal thread on the body by the external screw thread on the latter end to be fixed on the body.The leading portion of elastic sleeve is served as reasons and is formed a many resilient strip cylindraceous and constitute.The outer surface of elastic sleeve front end is a taper seat, and the internal conical surface of the same tapering on this outer conical surface and the thrust loose piece that makes it to produce radial contraction matches.The inner surface of elastic sleeve front end forms the taper seat of the tapering that requires for making pipe end.The thrust loose piece with can make it to produce reciprocating actuating unit and be connected.Actuating unit can be man-operated mechanism, also can be pneumatic mechanism.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1: vertical semi-section structural representation of pipe end shrink mouth device.
Among the figure: 1, body 2, elastic sleeve 3, thrust loose piece 4, actuating unit 5, pipe
Fig. 2: the drawing in side sectional elevation of elastic sleeve
Elastic sleeve (2) is fixed on by being threaded on the body (1).Its end is equipped with a locking nut, makes it further fixing.The inside and outside circle cone angle of elastic sleeve (2) front end, the gap between resilient strip and thrust loose piece (3) move back and forth distance, all according to the desired circular cone size of pipe end and the condition that just is in contact with one another and forms a cone when reaching this size between resilient strip calculate.The bar number of resilient strip increases along with the increase of pipe diameter, adopts six in the present embodiment.In the present embodiment, actuating unit (4) is to adopt manual lead-screw drive mechanism.When reversing leading screw, then promote to be attached thereto the thrust loose piece (3) that connects and move forward with hand.Because thrust loose piece (3) matches by taper seat with elastic sleeve (2), along with thrust loose piece (3) moves forward, the resilient strip on the elastic sleeve (2) just produces radial contraction, thereby presses to pipe (5), makes pipe end form desired taper shape.
Claims (1)
- A kind ofly the end of thin metallic tubd can be processed into conical pipe end shrink mouth device, it is characterized in that: it is made of body (1), elastic sleeve (2), thrust loose piece (3) and actuating unit (4); Be positioned at the elastic sleeve (2) of body, be to match with internal thread on the body (1) by the external screw thread on the latter end to be fixed on the body (1), the leading portion of elastic sleeve (2) is served as reasons and is formed a many resilient strip cylindraceous and constitute, the outer surface of elastic sleeve (2) front end is a taper seat, the internal conical surface of the same tapering on this outer conical surface and the thrust loose piece (3) that makes it to produce radial contraction matches, and the inner surface of elastic sleeve (2) front end forms the taper seat of the tapering that requires for making pipe end; Thrust loose piece (3) with can make it to produce reciprocating actuating unit (4) and be connected, actuating unit (4) can be man-operated mechanism, also can be pneumatic mechanism.
