Internal threaded pipe forming and receiving integrated production line

Abstract

The invention discloses an internal threaded pipe forming and receiving integrated production line. The production line comprises a placement device for receiving and releasing a metal hollow pipe tobe machined, a rotary forging head making machine for extruding the head section of the pipe into a solid shape, a spinning forming machine for performing internal thread forming machining on the pipeobtained after head making machining is performed, and a drawing device for performing drawing treatment on the pipe obtained after internal thread forming is performed. Particularly, the productionline further comprises a straightening device for performing straightening treatment on the pipe obtained after drawing treatment is performed, a length measuring device for measuring the length of the straightened pipe, a tension device for performing tension drawing treatment on the straightened pipe, a forming device for bending the pipe, and a take-up device for performing take-up operation onthe pipe. The production line can machine the pipe into a regular coil pipe, a user can conveniently use the pipe finally, and the yield and the production efficiency of the pipe are effectively ensured.

Description

technical field [0001] The invention relates to the technical field of metal pipe processing, and specifically provides an internally threaded pipe forming and receiving integrated production line. Background technique [0002] At present, in the field of precision seamless copper pipe processing, such as attached figure 1 and 2 The specific processing steps of the shown processing line are as follows: 1) first place the metal hollow pipe to be processed in the shape of a disk that has been transferred from the previous pass in the discharge frame of the discharge device 1, and the discharge frame is positioned Placed on the supporting plate 10A, and the supporting plate 10A can be rotated under the drive of the power unit (such as the combination of the frequency conversion motor 11A and the gear reducer) (see the attached Figure 4 shown); then the head section of the hollow pipe is inserted into the swaging head making machine 2 to realize that the head section of the h...

Problems solved by technology

[0006] However, since the above-mentioned traditional processing method adopts the "frame-to-frame" production method, it will cause the receiving box * The finished tube inside is rather messy, see attached image 3 As shown, this on the one hand will result in the receiving box * The finished tubes inside cannot be directly supplied as products after annealing, because the coils need to be annealed and packaged before they can be shipped to the user manufacturers; on the other hand, because the receiving frame * The finished pipe in the pipe needs to be transferred to the subsequent equipment for further processing. However, due to technical and usage reasons, it will be produced by dividing into small coils many times during processing, so the pipe will inevitably be produced in the subsequent production. Defects such as collisions, scratches, and random curls reduce the production efficiency and yield of pipes
