Description
Technical Field
The invention belongs to the technical field of additive manufacturing, and particularly relates to a mechanical additive repairing process.
Background
The metal material is easy to appear 'gnawing knife' and other phenomena in the machining process, so that the surface of the material has the defects of 'pits', and the like, and the quality is influenced.
At present, aiming at defects such as pits and the like caused by the phenomena such as knife biting and the like, the adopted repairing method mainly comprises the steps of welding additive materials, and ensuring the size of the materials through machining after welding.
However, some metal materials have poor welding performance and cannot be subjected to welding additive; some metal materials (such as rollers) are extremely easy to generate thermal stress and other influences on the body after welding, and are also unsuitable for welding additive materials.
Disclosure of Invention
The invention aims to solve the problems and provide a mechanical material-increasing repair process for overcoming the defects of pit and the like caused by the phenomena of cutter biting and the like of a metal material with poor welding performance or thermal stress after welding.
The technical scheme for realizing the aim of the invention is as follows: a mechanical material-increasing repair process adopts a mechanical roller device to squeeze redundant allowance of other parts of a metal material to pit defects; the mechanical roller device comprises a cutter bar, a pin shaft, a thrust bearing, a quenching roller and a nut; the pin shaft is arranged in a groove at the front part of the cutter bar and is fixed by the nut; the thrust bearing is connected with the pin shaft, the quenching roller is arranged on the outer side of the thrust bearing, and an arc flange is arranged at the peripheral end part of the quenching roller.
The metal material is a roller; the quenching roller 4 is made of quenched steel, and the hardness of a matrix is 63-68 HRC.
A sleeve is further arranged between the pin shaft and the groove at the front part of the cutter bar.
A gasket is further arranged between the thrust bearing and the front part of the cutter bar.
The invention has the positive effects that:
(1) The mechanical material-increasing repairing process of the invention is to squeeze the redundant allowance of the rest parts of the metal material to the pit defect part by designing a novel mechanical roller device, so that the metal material meets the inch requirement, and the problem of pit defect and the like caused by the phenomenon of cutter gnawing and the like in the machining process is solved.
(2) Compared with the traditional welding additive repairing process, the mechanical additive repairing process solves the additive repairing problem of the metal material with poor welding performance or thermal stress after welding, and has the advantages of low cost, short period and no welding defect.
