Problems solved by technology

[0002] In order to connect and fix the round pipe, embedded nuts are usually installed in the two pipe ends of the round pipe respectively. After the bolt passes through the bracket and is screwed into the embedded nut, the round pipe can be fixed on the bracket. The outer wall of the embedded nut In order to fit the cylindrical surface of the inner wall of the pipe end, the embedded nut is usually fixed to the pipe end by welding after being embedded in the pipe end of the round pipe. After the embedded nut is welded and fixed in the pipe end, it needs to be fixed. The solder joints at the pipe ends are ground, so fixing the embedded nuts in the pipe ends by welding will greatly increase the labor cost

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0015] Such as figure 1 As shown, the fixing method of the embedded nut at the pipe end is as follows:

[0016] (1) The outer diameter of the embedded nut 2 needs to be determined according to the inner diameter of the tube end of the round tube 1, so that the outer diameter of the embedded nut 2 is slightly larger than the inner diameter of the tube end of the round tube 1, so that when the embedded nut 2 is embedded in the end of the round tube 1 Can interfere with the pipe end; in this embodiment, the outer diameter of the embedded nut 2 is 0.1-0.3mm larger than the inner diameter of the pipe end of the round pipe 1;

[0017] (2) Three anti-rotation through grooves 3 arranged along the height direction of the embedded nut 2 are uniformly processed on the outer wall of the embedded nut 2;

[0018] (3) Prepare the push mold 4 that can ...

Abstract

The invention discloses a pipe end embedded nut fixing method which comprises the following steps: (1) determining the external diameter of an embedded nut according to the internal diameter of the pipe end of a circular pipe, wherein the embedded nut can be in interference fit with the pipe end when being embedded in the pipe end of the circular pipe; (2) processing at least two splining through grooves in the outer side wall of the embedded nut; (3) preparing a push-press die capable of embedding the embedded nut in the pipe end of the circular pipe in a push-press manner; and (4) driving the push-press die to move towards the pipe end of the circular pipe by a push-press device to enable the embedded nut to be embedded in the pipe end of the circular pipe under push and press of a push-press disc. As the embedded nut is in interference fit with the pipe end, the pipe end and the pipe wall at the splining through grooves are not strutted open outwards to be sunken in the splining through grooves inwards; and after the embedded nut is embedded in the pipe end of the circular pipe, a pressing plate on the push-press disc presses a circle of pipe wall at a pipe port inwards to reduce the diameter of the pipe port. With adoption of the pipe end embedded nut fixing method, the embedded nut can be rapidly and reliably fixed at the pipe end of the circular pipe.

Description

technical field [0001] The invention relates to the field of production technology of pipe fittings, in particular to a method for fixing embedded nuts at pipe ends. Background technique [0002] In order to connect and fix the round pipe, embedded nuts are usually installed in the two pipe ends of the round pipe respectively. After the bolt passes through the bracket and is screwed into the embedded nut, the round pipe can be fixed on the bracket. The outer wall of the embedded nut In order to fit the cylindrical surface of the inner wall of the pipe end, the embedded nut is usually fixed to the pipe end by welding after being embedded in the pipe end of the round pipe. After the embedded nut is welded and fixed in the pipe end, it needs to be fixed. The solder joints at the pipe ends are ground, so fixing the embedded nuts in the pipe ends by welding will greatly increase the labor cost.
