Abstract
Provided is a modified machine core shaft for machining an aluminium pipe. The modified machine core shaft comprises a first core shaft member and a second core shaft member, wherein an axial threaded hole is formed in the end face of one end of the first core shaft member, a threaded segment is arranged at one end of the second core shaft member, the second core shaft member is connected with the first core shaft member through the threaded segment and the axial threaded hole, and a central axis of the first core shaft member coincides with that of the second core shaft member. The first core shaft member and the second core shaft member are in threaded connection to form the modified machine core shaft. The first core shaft member and the second core shaft member can be machined respectively, and when hot processing is carried out, quenching deformation is small. The first core shaft member and the second core shaft member are connected in a threaded mode after positioned, and concentricity is good. The first core shaft member and the second core shaft member are in threaded connection to form the modified machine core shaft, the modified machine core shaft is convenient to disassemble, and production efficiency is improved.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to the machinery for the processing and packing aluminum pipe, particularly a kind of modification machine mandrel for the processing aluminum pipe.
Background technology:
Wrapping aluminum pipe adopts the modification machine to carry out the processing of inside pipe wall in production line, and the modification machine utilizes mandrel to extend in the aluminum pipe, the length of finishing aluminum pipe.In the prior art, modify the length of mandrel of machine all between 450 millimeters～500 millimeters, wherein the diameter of part mandrel is below 35 millimeters, elongated mandrel easy deformation like this, and machining and heat treatment is suitable difficulty all.
Summary of the invention:
The purpose of this utility model is to provide a kind of modification machine mandrel for the processing aluminum pipe, and described this modification machine mandrel for the processing aluminum pipe will solve prior art and be difficult to process technical problem for the elongated mandrel of modification machine.
This modification machine mandrel for the processing aluminum pipe of the present utility model, comprise first a mandrel member and second a mandrel member, wherein, be provided with an axial thread hole in the one end end face of the described first mandrel member, one end of the described second mandrel member is provided with a thread segment, the second mandrel member is connected the central axes of the central axis of the first mandrel member and the second mandrel member by described thread segment with the axial thread hole with the first mandrel member.
Further, described axial thread hole is bellmouth, and an end of the second mandrel member at thread segment place is tapered.
Further, be provided with a radial direction through hole in the first mandrel member, be provided with screw thread in the described radial direction through hole, the second mandrel member at one end is provided with a keyway or radial hole, be provided with a screw in the radial direction through hole, described screw front end extends in the keyway or radial hole of the second mandrel member.
Operation principle of the present utility model is: the first mandrel member and the second mandrel member constitute one by the back that is threaded and modify machine mandrel.The first mandrel member and the second mandrel member can be processed respectively, and quenching distortion is little during heat treatment.The first mandrel member and back, second mandrel member location are with being threaded good concentricity.
The utility model and prior art are compared, and its effect is actively with tangible.The utility model utilizes the first mandrel member and the second mandrel member to constitute one by the back that is threaded and modifies machine mandrel.The first mandrel member and the second mandrel member can be processed respectively, and quenching distortion is little during heat treatment.Back, the first mandrel member and second mandrel member location is with being threaded, good concentricity, and convenient disassembly has improved production efficiency.
